In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It should also be understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

Furthermore, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. That is, the appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather mean "one or more but not all embodiments" unless specifically stated otherwise.

The first embodiment is as follows:

during operation of the elevator, certain actions of the user, called tampering, disturb the operation of the elevator. Common tampering acts are: the elevator is closed by the action of pressing the buttons of each floor at will by hands, feet or other objects which continuously shield the light curtain of the elevator to prevent the elevator door (including the landing door and the car door) from being closed, or in the process of closing the door, the landing door and the car door are re-opened by the above means, and in the next process of closing the door, the action is repeated to prevent the elevator door from being closed. In the existing method, only the behavior of invalid calls can be recognized, and the disturbance behavior aiming at the elevator light curtain cannot be recognized.

In order to solve the technical problem, the embodiment of the application provides a shielding behavior identification method, which is applied to an elevator system, wherein the elevator system is respectively communicated with an elevator light curtain and a weighing device to acquire relevant information of the elevator light curtain and the weighing device, and then whether a tampering behavior exists in an elevator is judged according to the acquired relevant information. Specifically, after the elevator system acquires the triggering time of the elevator light curtain (i.e., the time when the elevator light curtain starts to be shielded, or the time when the elevator light curtain starts to be shielded and the time when the elevator light curtain finishes to be shielded), the elevator system acquires a corresponding weight value from the weighing device according to the acquired triggering time, and finally determines whether the elevator has a tampering behavior by combining the weight value.

Because when the elevator light curtain is sheltered from the back, there is the user to get into the elevator usually, or walk out the elevator, and the user gets into or walks out the elevator and will change the weight value of elevator, consequently, cuts apart the weight value according to the triggering moment that the action of sheltering from the elevator light curtain obtained, carries out the discernment of behavior of being in disorder according to the weight value that cuts apart the acquisition again, can effectively discern the behavior of being in disorder to the elevator light curtain.

The following describes an occlusion behavior identification method provided in an embodiment of the present application with reference to the drawings.

Fig. 1 shows a flowchart of a first occlusion behavior identification method provided in an embodiment of the present application, which is applied to an elevator system, and is detailed as follows:

and S11, acquiring the triggering time of the elevator light curtain, wherein the triggering time is the time when the elevator light curtain starts to be shielded or the time when the elevator light curtain finishes to be shielded.

The elevator light curtain is an elevator door safety protection device made according to the photoelectric sensing principle, and the working principle is as follows: when no obstacle exists in the elevator door to the obstacle exists, the level detected by the elevator light curtain changes (from 0 to 1), and the subsequent moment when the level changes is sent to the elevator system as the moment when the elevator light curtain starts to be shielded by the elevator light curtain; when the elevator door is internally blocked to be free from the blockage, the level detected by the elevator light curtain is changed (from 1 to 0), and the subsequent time when the level is changed is sent to the elevator system by the elevator light curtain as the time when the elevator light curtain is blocked.

In some scenes, if the user gets in and out of the elevator at normal walking speed, the elevator light curtain will detect the moment when the elevator light curtain starts to be shielded and the moment when the elevator light curtain finishes to be shielded in a short time, at this moment, the elevator system can obtain the moment when the elevator light curtain starts to be shielded in a short time, and the moment when the elevator light curtain finishes to be shielded, namely, the elevator system will obtain 2 trigger moments in a short time. Certainly, if a plurality of people get in and out of the elevator, the elevator system will continuously obtain a plurality of time information (for example, the time when a plurality of elevator light curtains start to be shielded and the time when a plurality of elevator light curtains end to be shielded) from the elevator light curtain, that is, obtain a plurality of trigger times.

In some scenes, if a user puts hands or feet in the two elevator doors for a long time, the elevator light curtain can only determine the moment when the elevator light curtain starts to be shielded and cannot determine the moment when the elevator light curtain finishes being shielded in a short time. At the moment, the elevator system can only acquire the trigger moment corresponding to the moment when the elevator light curtain starts to be shielded, namely 1 trigger moment.

In this embodiment, the elevator light curtain can send the trigger time it has obtained to the elevator system in real time.

In some embodiments, considering that the elevator light curtain is usually started after the elevator reaches the stopping floor and is not started during the operation of the elevator, this embodiment can acquire the triggering time only after the elevator reaches the stopping floor, that is, step S11 described above includes:

and acquiring the triggering time of the elevator light curtain after the elevator reaches the current stopping layer.

Here, the stop floor means a floor that can be reached by the elevator, and for example, if the floor that can be reached by the elevator a is a single floor and the floor that can be reached by the elevator B is an even floor, the floors of the single floors such as the floor 3, the floor 5, and the floor 7 are all floors that can be reached by the elevator a, and the floors of the even floors such as the floor 2, the floor 4, and the floor 6 are all floors that can be reached by the elevator B. If the floor at which the elevator A currently stops is the floor 3, the current stopping floor corresponding to the elevator A is the floor 3.

In the embodiment, the elevator can only stop at one floor at a time, so that the triggering time of the current stopping layer is only obtained, and the shielding behavior of the current stopping layer can be accurately analyzed subsequently.

And S12, acquiring the weight value of the elevator collected by the weighing device based on the trigger moment.

Wherein, weighing device sets up on the elevator for gather the weight value of this elevator. Specifically, the weighing device may perform the collecting operation at a preset frequency, or may perform the collecting operation after receiving the trigger signal.

In this embodiment the weight value obtained by the elevator system is related to the obtained triggering moment, which is related to the beginning and the end of the shielding of the elevator light curtain, i.e. the behavior of shielding the elevator light curtain. Because the user all needs to pass through the lift-cabin door in business turn over the elevator, consequently, the user is passed in and out the elevator and all can be detected by elevator light curtain, and behind the user business turn over the elevator, can make the weight of elevator change usually, promptly, obtains corresponding weight value according to the trigger moment who obtains and is favorable to follow-up more accurate discernment result that obtains.

In some embodiments, if the memory of the weighing apparatus is small, the weighing apparatus only records the weight value detected by the weighing apparatus within the last time (for example, the last 2 minutes), or records the last limited weight value, that is, no matter how many weight values the weighing apparatus has collected, but if the memory of the weighing apparatus is small, the weighing apparatus only records the limited weight value. For example, only the last 5 weight values detected by the elevator system are recorded, and at most 5 weight values can be obtained by the elevator system from the weighing device.

Of course, if the weighing device has more memory, the weighing device may record the weight value for a longer time (such as the last 10 minutes), which is not limited herein.

And S13, identifying whether the behavior of shielding the elevator light curtain is a disturbing behavior or not according to the weight value.

In this embodiment, whether the behavior of sheltering from elevator light curtain that the weight value that obtains corresponds is the behavior of disturbing through the characteristic law that whether the characteristic of the weight value that the analysis obtained accords with the weight value that various behaviors of disturbing correspond, judges the weight value that obtains whether the behavior of sheltering from elevator light curtain is the behavior of disturbing. Wherein, the characteristic rule of the weight value that various behavior of disturbing corresponds can be confirmed through following mode: and carrying out curve fitting on the weight values corresponding to various tampering behaviors, or analyzing the weight values, and the like.

In this application embodiment, because the moment of triggering is the moment that the elevator light curtain begins to be sheltered from, perhaps, for the moment that the elevator light curtain finishes being sheltered from, that is, when the elevator system acquires the moment of triggering, indicate that there is the action of sheltering from to the elevator light curtain, consequently, when obtaining the weight value of elevator according to the moment of triggering that obtains, only acquire the weight value that there is the action of sheltering from to correspond, like this, when the weight value of follow-up acquireing carries out the discernment of behavior of disturbing, can effectively discern the behavior of disturbing in order to the elevator light curtain to improve the degree of accuracy of discernment.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

Example two:

fig. 2 shows a flowchart of a second occlusion behavior identification method provided in an embodiment of the present application, where step S21 is used to define step S11 of the first embodiment, step S22 and step S23 are used to define step S12 of the first embodiment, and step S24 is used to define step S13 of the first embodiment, and details are as follows:

and S21, acquiring the triggering time of the elevator light curtain.

In some embodiments, the step S21 includes:

The stopping floor refers to a floor where the elevator can reach, and the current stopping floor refers to a floor where the elevator stops currently.

Step S22, if the number of the trigger time is odd within the time period from the time when the elevator reaches the current stop floor to the current time, calculating the shielding duration of the latest shielding behavior according to the current time and the latest acquired trigger time; if the number of the acquired triggering moments is even within the time period from the moment when the elevator reaches the current stop floor to the current moment, the shielding duration of the latest shielding behavior is calculated according to the moment when the newly acquired elevator light curtain finishes being shielded and the moment when the newly acquired elevator light curtain starts being shielded.

In this embodiment, if in the period from the time when the elevator stops to the current time, the elevator system acquires odd number of trigger times from the elevator light curtain, which indicates that in the last blocking behavior, the elevator light curtain only detects that the elevator light curtain starts to be blocked, but does not detect that the elevator light curtain ends to be blocked (only a rising edge occurs, and no falling edge occurs), that is, the last blocking behavior may be a tampering behavior in which a user intentionally blocks the elevator light curtain by using hands, feet, or the like, and then the blocking duration during which the elevator light curtain is blocked is calculated according to the latest acquired trigger time and the current time. For example, if the latest acquired trigger time (i.e., the latest starting time of the elevator light curtain to be blocked) is 7 point 06 minute 1 second, and the current time is 7 point 07 minute 5 seconds, the blocking time of the elevator light curtain to be blocked is 1 minute 4 seconds.

Of course, if the number of the acquired trigger times is an even number in the time period from the time when the elevator reaches the current stop floor to the current time, it indicates that the current time is the time when the elevator light curtain ends being shielded, or indicates that the last shielding action is finished and no new shielding action is generated, at this time, the shielding duration of the latest shielding action is calculated according to the time when the latest acquired elevator light curtain ends being shielded and the time when the latest acquired elevator light curtain starts being shielded.

Step S23, if the shielding duration is greater than a preset duration threshold, acquiring at least two first weight values within the shielding duration, where the first weight values are acquired by the weighing apparatus at a preset frequency.

The preset time threshold may be 20 seconds, and the preset frequency may be 10Hz (hertz).

In this embodiment, it is considered that the internal memory of the weighing device is limited, and therefore, after the weighing device collects the weight value of the elevator at a preset frequency, only a limited weight value is stored. For example, assuming that the weighing apparatus only stores 2 weight values, a1 and a2, a1 is the larger weight value and a2 is the smaller weight value, after a new weight value is detected, the new weight value is compared with a1 and a2, respectively, if the new weight value is greater than a1, the new weight value is assigned to a1, if the new weight value is less than a2, the new weight value is assigned to a2, otherwise, the new weight value is discarded. Of course, if the weighing device only stores 2 weight values, the subsequent elevator system can only obtain 2 weight values from the weighing device.

And S24, if the first weight values are equal, identifying the behavior of shielding the elevator light curtain in the current stop layer as a disturbing behavior.

In this embodiment, if it is determined that the obtained first weight values are equal, for example, if a1 and a2 are equal, it indicates that no goods and no person enter or exit the elevator, that is, the user intentionally shields the elevator light curtain, and at this time, it is determined that the shielding behavior is a tampering behavior.

In the embodiment of the application, the obtained trigger time is the trigger time in the period from the time when the elevator reaches the current stop floor to the current time, so that the trigger time obtained by an elevator system can accurately reflect whether the elevator is blocked on the current stop floor, and at least two weight values (namely, first weight values) obtained from the weighing device are equal when the blocking time is longer, so that the situation that no goods or personnel enter or exit the elevator in the period when an elevator light curtain is blocked is shown, otherwise, the first weight values obtained from the weighing device cannot be equal, namely, through the mode, whether the blocking behavior is a garbled behavior can be accurately identified.

In some embodiments, if, in a period from the time when the elevator reaches the current stop floor to the current time, the number of the obtained trigger times is greater than 1, the blocking duration is not greater than a preset duration threshold, and each trigger time generates a trigger signal, where the trigger signal is used to trigger the weighing device to collect the weight value of the elevator, so as to obtain a second weight value, the step S12 includes:

and acquiring second weight values corresponding to at least two adjacent trigger signals.

Correspondingly, the step S13 includes:

if each second weight value is equal and the second weight value is smaller than a preset weight threshold value, identifying the behavior of shielding the elevator light curtain in the current stop layer as a disturbing behavior.

The preset weight threshold is a weight value corresponding to the child, and for example, the weight threshold may be set to 40 kilograms (kg).

In this embodiment, when the elevator system acquires at least two trigger times, it indicates that at least one of the trigger times has a time when the elevator light curtain starts to be blocked and a time when the elevator light curtain ends to be blocked. The moment that each elevator light curtain begins to be sheltered from all generates a trigger signal to and, the moment that each elevator light curtain finishes being sheltered from all generates a trigger signal, and these trigger signals will be sent to weighing device, and every time this weighing device receives a trigger signal, this weighing device all carries out the collection action of weight value to the elevator.

In this embodiment, after acquiring at least two adjacent triggering times, the elevator system acquires adjacent second weight values corresponding to the triggering times from the weighing device, for example, acquires second weight values equal to the number of the triggering times, wherein the two adjacent second weight values are acquired by triggering the weighing device by two adjacent triggering signals. The second weight values obtained by the elevator system are equal, so that the situation that no goods or people enter and exit in the time period of the adjacent trigger moments is shown, and the second weight value is smaller than the preset weight threshold value, so that the situation that the current shielding action is repeatedly shielding the elevator light curtain by children is shown with a high probability. That is, according to the identification method, the disturbance behavior of repeatedly shielding the elevator light curtain can be accurately identified.

Of course, the elevator system may also acquire only the second weight value corresponding to the most recently acquired second predetermined number (which may be 3) of trigger moments from the weighing device after acquiring the first predetermined number (which may be 5) of trigger moments. Since the tampering behavior is a behavior of blocking the elevator light curtain for multiple times, after the first preset number of trigger times are obtained, only the second weight values corresponding to the second preset number of trigger times which are obtained recently are analyzed, and therefore, the accuracy of the identification result can be further improved.

In some embodiments, the step S13 further includes:

a1, if the second weight values are not equal, selecting two adjacent second weight values from the second weight values.

A2, if the maximum weight value is larger than a first preset multiple of a larger value of the two selected second weight values, and the minimum weight value is smaller than a second preset multiple of a smaller value of the two selected second weight values, identifying a behavior of shielding the elevator light curtain in the current parking layer as a disturbing behavior, wherein the maximum weight value and the minimum weight value are respectively a maximum first weight value and a minimum first weight value which are acquired by the weighing device between the two selected second weight values, the first preset multiple is larger than 1, and the second preset multiple is smaller than 1.

The first preset multiple may be set to 150%, and the second preset multiple may be set to 50%.

In this embodiment, it is considered that the detected weight values at different times are different, which may be caused by the elevator riding person jumping or running in the car, and these actions cause the weight values detected by the weighing device to have specific relationships. For example, assuming that a1 is the maximum weight value and a2 is the minimum weight value, two second weight values b1 and b2 are selected, and b1 is greater than b2. If the elevator system judges that a1 is larger than b1 × 150% and a2 is smaller than b2 × 50%, the elevator is judged to have jumping or running behavior, namely, the behavior of shielding the elevator light curtain is judged to be a disturbing behavior.

In this embodiment, it is also considered that when the selected second weight values are not equal, the corresponding blocking behavior may be a disturbing behavior such as jumping, and therefore, by further determining the different second weight values, the disturbing behavior of blocking the elevator light curtain can be further screened out.

In some embodiments, considering that the tampering behavior may also be a behavior corresponding to the same elevator-taking person moving back and forth in the elevator, the first weight value acquired by the weighing device at the pre-determined frequency may be analyzed to determine whether the shielding behavior is a behavior corresponding to the same elevator-taking person moving back and forth in the elevator. At this time, step S13 includes:

and B1, determining the increasing and decreasing change times according to the plurality of first weight values, wherein the increasing and decreasing change times are increased by 1 when the first weight values are changed from small to large or the first weight values are changed from large to small.

In this embodiment, if the elevator stops at one floor and 2 elevator passengers are continuously removed from the elevator so that the first weight value becomes smaller, the number of times of change is changed from 0 to 1 (if only 1 elevator passenger is removed from the elevator, the number of times of change is also changed from 0 to 1). Then, if someone (the number of people is not limited) needs to take the elevator, that is, to walk into the elevator from outside the elevator, and the first weight value becomes large, the number of times of change of increase and decrease becomes 2.

In some embodiments, in order to avoid a change in weight value caused by elevator shake or the like as a change in the first weight value, noise reduction processing may be performed on the plurality of obtained first weight values first. For example, a curve composed of a plurality of first weight values is filtered by a filter to filter out small-amplitude fluctuations in the curve.

And B2, determining the shielding times of the elevator light curtain, wherein the shielding times are equal to the numerical value obtained by rounding half of the acquired triggering time.

In this embodiment, if the number of the trigger times is 2, the shielding frequency of the elevator light curtain is 1, and if the number of the trigger times is 3, the shielding frequency of the elevator light curtain is 1. The shielding times can be calculated in the following way: and carrying out derivation calculation on a curve consisting of a plurality of first weight values to obtain a derivation curve, wherein the positive and negative change times corresponding to the derivation curve are the shielding times of the elevator light curtain.

And B3, if the increase and decrease change times are not more than the shielding times, identifying the behavior of shielding the elevator light curtain in the current stop layer as a disturbing behavior.

In the embodiment, the behavior that a person enters or exits the elevator for multiple times can be identified through the mode, so that the behavior of disturbing shielding the elevator light curtain can be further screened out.

Example three:

fig. 3 shows a flowchart of a third method for identifying an occlusion behavior according to an embodiment of the present application, where step S32 is used to define step S11 of the first embodiment, step S33 and step S34 are used to define step S12 of the first embodiment, and step S35 is used to define step S13 of the first embodiment, and the following is detailed as follows:

and S31, acquiring a third weight value, wherein the third weight value is acquired by the weighing device at the moment when the elevator reaches the current stop floor.

In this embodiment, in order to facilitate distinguishing from the weight values obtained at different times in the above embodiments, the elevator stops at the current stop floor, and the weight value corresponding to the time when the elevator system stops, which is obtained from the weighing device by the elevator system, is referred to as a third weight value.

In some embodiments, in order to reduce the memory usage of the weighing device by the recorded weight values, the weighing device only collects the weight values of the elevator at certain times, e.g. only after the elevator has stopped at the current stopping floor, the elevator system then obtains the third weight values it recorded from the weighing device.

In this embodiment, since only one third weight value is recorded, it is not necessary to occupy more memory of the weighing apparatus.

And step S32, acquiring the triggering time of the elevator light curtain.

In some embodiments, the step S32 includes:

Step S33, if the number of the acquired trigger time is odd within the time period from the time when the elevator reaches the current stop floor to the current time, calculating the shielding duration of the latest shielding behavior according to the current time and the latest acquired trigger time; if the number of the acquired trigger time is even within the time period from the time when the elevator reaches the current stop floor to the current time, calculating the shielding duration of the latest shielding action according to the latest acquired time when the elevator light curtain is stopped being shielded and the latest acquired time when the elevator light curtain starts being shielded.

And step S34, if the shielding time length is longer than the preset interval time length, acquiring at least one fourth weight value, wherein each time the shielding time length is equal to an integer multiple of the preset interval time length, the weighing device acquires one fourth weight value.

In this embodiment, if only odd number of trigger times are obtained from the time when the elevator reaches the stop floor, that is, the time when the elevator light curtain finishes being shielded is not detected in the last shielding action, if the time from the time when the elevator light curtain starts being shielded to the current time (that is, the last shielding time) is longer, it indicates that the elevator light curtain is continuously shielded in the last shielding action. Therefore, when the elevator system only acquires odd number of trigger time, the shielding duration corresponding to the shielding action is counted according to the latest acquired trigger time and the current time, and when the counted shielding duration is a multiple (such as an integer multiple) of the preset interval duration, the weighing device performs a weight value acquisition action, that is, the elevator system also acquires each fourth weight value at preset intervals. For example, assuming that the preset interval duration is 10 seconds, when the elevator system acquires only 1 trigger time, and the blocking durations are 10 seconds, 20 seconds, and 30 seconds, respectively, the weighing device acquires and records a fourth weight value, that is, the elevator system acquires a fourth weight value every 10 seconds.

And step S35, if the third weight value is equal to any one of the fourth weight values, identifying the behavior of shielding the elevator light curtain in the current stop floor as a disturbing behavior.

In this embodiment, if the elevator system determines that the third weight value is not equal to the first obtained fourth weight value, the first obtained fourth weight value is assigned to the third weight value, but after the preset interval duration, the second fourth weight value can be obtained from the weighing device, the third weight value is continuously compared with the second obtained fourth weight value, and if the third weight value is equal to the second obtained fourth weight value, it is determined that the blocking behavior of the current landing floor is a tampering behavior.

In the embodiment of the application, because the weighing device only records a third weight value when the elevator reaches the stopping layer and records the fourth weight value of corresponding quantity when the shielding time is an integer multiple of the preset interval time, the weighing device does not need to record excessive weight values, and the memory of the weighing device is effectively saved. In addition, because the fourth weight value can be obtained when the shielding time length meets the correlation between the shielding time length and the preset interval time length, if the elevator system obtains one fourth weight value, the shielding time length is longer, and meanwhile, if the fourth weight value is equal to the third weight value, no goods or people enter and exit the elevator in the shielding time length, namely, the elevator light curtain can be accurately identified to at least shield the preset time interval according to the identification mode, and no goods or people enter and exit the elevator to correspond to the disturbing behavior.

In some embodiments, if the number of the acquired trigger times is greater than 1 and the blocking duration is not greater than the preset interval duration in the period from the time when the elevator reaches the current stop floor to the current time, the step S12 further includes:

and acquiring at least two fifth weight values, wherein the fifth weight values are acquired by the weighing device at the moment when the elevator light curtain is blocked.

Specifically, the elevator light curtain generates a trigger signal when detecting that the elevator light curtain is blocked, and sends the trigger signal to the weighing device, or the elevator light curtain generates a trigger signal when detecting that the elevator light curtain starts to be blocked and when the elevator light curtain is blocked, and only sends the trigger signal corresponding to the moment when the elevator light curtain is blocked to the weighing device, and the weighing device collects the weight value of the elevator once again. Or the elevator light curtain sends the trigger signal corresponding to the moment when the shielding is started and the trigger signal corresponding to the moment when the shielding is finished to the weighing device, but the weighing device only collects the weight value of the elevator according to the trigger signal corresponding to the moment when the shielding is finished. Alternatively, the weighing device collects the weight value of the elevator based on the trigger signal corresponding to the time at which the shielding operation is started and the trigger signal corresponding to the time at which the shielding operation is ended, but the elevator system only obtains the weight value (i.e., the fifth weight value) corresponding to the time at which the shielding operation is ended.

Because when the elevator stops, the weighing device acquires a third weight value, and when the shielding action is just generated (namely the moment when the elevator light curtain starts to be shielded), the weight value of the elevator may not be changed, and the fifth weight value obtained by subsequent direct use is considered to be compared with the third weight value, so that the elevator system only acquires the weight value (namely the fifth weight value) corresponding to the moment when the elevator light curtain finishes to be shielded, and the accuracy of a subsequent identification result can be improved.

Correspondingly, the step S13 includes:

if at least two fifth weight values equal to the third weight value exist in the obtained fifth weight values, and the third weight value is smaller than a preset weight threshold, the behavior of shielding the elevator light curtain in the current stop layer is identified as a disturbing behavior.

Specifically, the comparison of the fifth weight value and the third weight value may be performed in the following manner: one is that the weighing device registers at least two fifth weight values and one third weight value, from which the elevator system acquires the at least two fifth weight values and the third weight value before comparing them. The other is that the weighing device only records two weight values, specifically, the weighing device firstly records a third weight value M, records a fifth weight value N1 when the shielding action is finished (the moment when the elevator light curtain is shielded is finished), compares the M and the N1, and sets a preset number of times X = X-1 (assuming that the original value of X is 2) if M and N1 are equal, namely, currently X =2-1; if M and N1 are not equal, a preset number X =2 is set, and let M = N1. And subsequently obtaining a new fifth weight value N2, comparing the N2 with the M, and when X =0 and M is smaller than a preset weight threshold, indicating that the current shielding behavior is that the child shields the elevator light curtain to prevent the elevator from closing the door, namely identifying that the current shielding behavior is a tampering behavior.

In this embodiment, because the weight value that this elevator corresponds when the third weight value is the elevator and parks, and the weight value that the moment that the fifth weight value was ended for sheltering from the action corresponds, consequently, through the comparison of third weight value and fifth weight value, can judge whether have goods or personnel business turn over elevator during sheltering from the action, if do not have goods or personnel business turn over elevator, and judge that the third weight value is less, then show that shelter from the elevator light curtain for children in the elevator many times at present, thereby can accurately discern that the current action of sheltering from is for the behavior of being confused. In addition, because the weighing device only needs to record a limited weight value, the memory required by the weighing device can be effectively saved.

In some embodiments, in order to facilitate the manager to know the tampering behavior existing in the elevator in time, after identifying the tampering behavior, the method further includes:

and sending the scrambling information to a designated terminal, wherein the scrambling information comprises the identifier of the elevator with the scrambling behavior.

In this embodiment, the designated terminal may be a mobile phone of an elevator worker, or a mobile phone of a property manager, or a monitor of an elevator. Because appointed terminal can obtain the sign of elevator in this disturbing information after can receiving the signal of disturbing, and then look over the condition that corresponds the elevator according to the sign of this elevator, consequently, elevator system sends the disturbing information for appointed terminal, is favorable to managers in time to follow up the disturbing action that the elevator exists, and then selects further operation to can improve the security of elevator.

In some embodiments, in order to reduce the effect of the tampering behavior on the elevator in time, after the sending of the tampering information to the designated terminal, the method includes:

receiving feedback information, wherein the feedback information comprises voice information or a door closing signal.

In this embodiment, the feedback information may be sent by the designated terminal, or may be sent by other devices. For example, suppose that the elevator system sends the tamper information to a mobile phone of an elevator worker, the elevator worker checks a corresponding monitoring video in a monitoring room of the elevator, and sends feedback information to the elevator system through equipment of the monitoring room, and the elevator system sends specific information to the elevator, for example, if the feedback information includes a door closing signal, the elevator system sends the door closing signal to the elevator, that is, remotely controls the elevator to close the door. If the feedback information comprises voice information, the elevator system sends the voice information to the audio equipment installed on the elevator, so that the audio equipment plays the voice information, and the purpose of remotely reminding people who send out the disorderly behaviors is achieved.

In some embodiments, further comprising:

if the tampering behavior is not recognized and the elevator door is closed, the weighing device is informed to stop collecting the weight value.

In this embodiment, judge that current the action of sheltering from is not the behavior of disturbing in case the elevator system is according to the weight value that obtains, and judge that the lift-cabin door has closed the door, for example, the layer door of elevator has closed, and the weight value of elevator can not change again after the lift-cabin door closes, consequently, this weighing device's resource can effectively be saved to weight value that this weighing device suspends to gather. And collecting the elevator when the elevator reaches a new stopping floor, or collecting the elevator again when the elevator light curtain is shielded.

Example four:

fig. 4 shows a block diagram of the occlusion behavior recognition device according to the embodiment of the present application, and for convenience of description, only the parts related to the embodiment of the present application are shown.

This shelter from action recognition device 4 is applied to elevator system, includes: a trigger time obtaining module 41, a weight value obtaining module 42 and a shielding behavior recognizing module 43, wherein:

the triggering time obtaining module 41 is configured to obtain a triggering time of the elevator light curtain, where the triggering time is a time when the elevator light curtain starts to be blocked or a time when the elevator light curtain finishes being blocked.

The elevator light curtain is an elevator door safety protection device made according to the photoelectric sensing principle, and the working principle is as follows: when no obstacle exists in the elevator door to the obstacle exists, the level detected by the elevator light curtain changes (changes from 0 to 1), and the subsequent moment when the level changes is sent to an elevator system as the moment when the elevator light curtain starts to be shielded by the elevator light curtain; when the elevator door is internally blocked to be free from the blockage, the level detected by the elevator light curtain is changed (from 1 to 0), and the subsequent time when the level is changed is sent to the elevator system by the elevator light curtain as the time when the elevator light curtain is blocked.

In some scenes, if the user gets in and out of the elevator at normal walking speed, the elevator light curtain will detect the moment when the elevator light curtain starts to be shielded and the moment when the elevator light curtain finishes to be shielded in a short time, at this moment, the elevator system can obtain the moment when the elevator light curtain starts to be shielded and the moment when the elevator light curtain finishes to be shielded in a short time, that is, the elevator system will obtain 2 trigger moments in a short time. Of course, if a plurality of people enter and exit the elevator, the elevator system will continuously obtain a plurality of time information (for example, the time when a plurality of elevator light curtains start to be shielded and the time when a plurality of elevator light curtains end to be shielded) from the elevator light curtain, and the like, that is, obtain a plurality of trigger times.

In some scenes, if a user puts hands or feet in the two elevator doors for a long time, the elevator light curtain can only determine the moment when the elevator light curtain starts to be shielded and cannot determine the moment when the elevator light curtain finishes being shielded in a short time. At this time, the elevator system can only obtain the trigger time corresponding to the time when the elevator light curtain starts to be shielded in a short time, namely obtain 1 trigger time.

In some embodiments, considering that the elevator light curtain is usually started after the elevator reaches the stopping floor and is not started during the operation of the elevator, this embodiment can acquire the trigger time only after the elevator reaches the stopping floor, that is, the trigger time acquisition module 41 is specifically configured to:

And a weight value obtaining module 42, configured to obtain the weight value of the elevator collected by the weighing device based on the trigger time.

And the shielding behavior identification module 43 is used for identifying whether the behavior of shielding the elevator light curtain is a disturbing behavior according to the weight value.

In this application embodiment, because the moment of triggering is the moment that the elevator light curtain begins to be sheltered from, perhaps, for the moment that the elevator light curtain finishes being sheltered from, that is to say, when the elevator system acquires the moment of triggering, indicate to have the action of sheltering from to the elevator light curtain, consequently, when obtaining the weight value of elevator according to the moment of triggering that obtains, only acquire the weight value that has the action of sheltering from and correspond, like this, when the weight value of follow-up acquireing carries out the discernment of behavior of being confused, not only can effectively discern the behavior of being confused to the elevator light curtain, also can improve the degree of accuracy of discernment.

In some embodiments, the weight value obtaining module 42 includes: a shielding time length calculating unit and a first weight value obtaining unit. Wherein:

the shielding duration calculation unit is used for calculating the shielding duration of the latest shielding behavior according to the current time and the latest acquired trigger time if the acquired trigger time is an odd number in the period from the time when the elevator reaches the current stop floor to the current time; if the number of the acquired trigger time is even within the time period from the time when the elevator reaches the current stop floor to the current time, calculating the shielding duration of the latest shielding action according to the latest acquired time when the elevator light curtain is stopped being shielded and the latest acquired time when the elevator light curtain starts being shielded.

The shielding duration refers to the shielding duration of a single shielding of the elevator light curtain.

In this embodiment, if in the period from the time when the elevator stops to the current time, the elevator system only obtains odd number of trigger times from the elevator light curtain, which indicates that in the last blocking behavior, the elevator light curtain only detects that the elevator light curtain starts to be blocked, but does not detect that the elevator light curtain ends to be blocked (only a rising edge occurs, and no falling edge occurs), that is, the near blocking behavior may be a disturbing behavior in which the user intentionally blocks the elevator light curtain by using hands, feet, and the like, and then the blocking duration in which the elevator light curtain is blocked is calculated according to the newly obtained trigger time and the current time. For example, if the latest acquired trigger time (i.e., the latest starting time of the elevator light curtain to be blocked) is 7 point 06 minute 1 second, and the current time is 7 point 07 minute 5 seconds, the blocking time of the elevator light curtain to be blocked is 1 minute 4 seconds.

Certainly, if the number of the acquired trigger moments is an even number within a time period from the moment when the elevator reaches the current stop floor to the current moment, the current moment is the moment when the elevator light curtain finishes being shielded, or the last shielding action is finished and no new shielding action is generated, at this moment, the shielding duration of the latest shielding action is calculated according to the latest acquired moment when the elevator light curtain finishes being shielded and the latest acquired moment when the elevator light curtain starts being shielded.

The first weight value acquisition unit is used for acquiring at least two first weight values in the shielding time length if the shielding time length is greater than a preset time length threshold value, and the first weight values are acquired by the weighing device at a preset frequency.

In this embodiment, it is considered that the internal memory of the weighing device is limited, and therefore, after the weighing device collects the weight value of the elevator at a preset frequency, only a limited weight value is stored. For example, assuming that the weighing apparatus only stores 2 weight values, a1 and a2, a1 being the larger weight value and a2 being the smaller weight value, after a new weight value is detected, the new weight value is compared with a1 and a2, respectively, if the new weight value is greater than a1, the new weight value is assigned to a1, if the new weight value is less than a2, the new weight value is assigned to a2, otherwise, the new weight value is discarded. Of course, if the weighing device only stores 2 weight values, the subsequent elevator system can only acquire 2 weight values from the weighing device.

Correspondingly, the occlusion behavior identification module 43 is specifically configured to:

if each first weight value is equal, the behavior of shielding the elevator light curtain in the current stop layer is identified as a disturbing behavior.

In the embodiment of the application, the acquired trigger time is the trigger time in the time period from the time when the elevator reaches the current stop floor to the current time, so that the trigger time acquired by the elevator system can accurately reflect whether the elevator is blocked on the current stop floor, and at least two weight values (namely, first weight values) acquired from the weighing device are equal when the blocking time is long, so that no goods or personnel enter and exit the elevator in the time period when the elevator light curtain is blocked, otherwise, the first weight values acquired from the weighing device cannot be equal, that is, whether the blocking behavior is a nuisance behavior can be accurately identified through the above mode.

In some embodiments, if, in a period from a time when the elevator reaches the current stop floor to a current time, the number of the acquired trigger times is greater than 1, the blocking time is not greater than a preset time threshold, and each trigger time generates a trigger signal, where the trigger signal is used to trigger the weighing device to acquire the weight value of the elevator, so as to obtain a second weight value, the weight value acquiring module 42 is specifically configured to:

Correspondingly, the occlusion behavior recognition module 43 is specifically configured to:

The preset weight threshold is a weight value corresponding to a child, and for example, the weight threshold may be set to 40 kilograms (kg).

In this embodiment, after acquiring at least two adjacent triggering instants, the elevator system will acquire adjacent second weight values corresponding to the triggering instants from the weighing device, for example, the second weight values equal to the number of the triggering instants, wherein the two adjacent second weight values are acquired by triggering the weighing device by two adjacent triggering signals. The second weight values obtained by the elevator system are equal, so that the situation that no goods or people enter and exit in the time period of the adjacent trigger moments is shown, and the second weight value is smaller than the preset weight threshold value, so that the situation that the current shielding action is repeatedly shielding the elevator light curtain by children is shown with a high probability. That is, according to the identification method, the disturbance behavior of repeatedly shielding the elevator light curtain can be accurately identified.

Of course, the elevator system may also acquire only the second weight value corresponding to the most recently acquired second predetermined number (which may be 3) of triggering times from the weighing device after acquiring the first predetermined number (which may be 5) of triggering times. Since the tampering behavior is a behavior of blocking the elevator light curtain for multiple times, after the first preset number of trigger times are obtained, only the second weight values corresponding to the second preset number of trigger times which are obtained recently are analyzed, and therefore, the accuracy of the identification result can be further improved.

In some embodiments, the occlusion behavior recognition module 43 is further configured to:

if the second weight values are not equal, two adjacent second weight values are selected from the second weight values; if the maximum weight value is greater than a first preset multiple of a larger value of the two selected second weight values, and the minimum weight value is less than a second preset multiple of a smaller value of the two selected second weight values, identifying a behavior of shielding the elevator light curtain in the current stop floor as a disturbing behavior, wherein the maximum weight value and the minimum weight value are respectively a maximum first weight value and a minimum first weight value acquired by the weighing device between the two selected second weight values, the first preset multiple is greater than 1, and the second preset multiple is less than 1.

In some embodiments, considering that the tampering behavior may also be a behavior corresponding to the same elevator-taking person moving back and forth in the elevator, the first weight value acquired by the weighing device at the pre-determined frequency may be analyzed to determine whether the shielding behavior is a behavior corresponding to the same elevator-taking person moving back and forth in the elevator. In this case, the blocking behavior recognition module 43 includes:

and an increasing/decreasing change frequency determining unit for determining the increasing/decreasing change frequency according to the plurality of first weight values, wherein the increasing/decreasing change frequency is increased by 1 when the first weight value is changed from small to large or the first weight value is changed from large to small.

In this embodiment, if the elevator stops at one floor and 2 elevator passengers are continuously removed from the elevator so that the first weight value becomes small, the number of times of change is changed from 0 to 1 (if only 1 elevator passenger is removed from the elevator, the number of times of change is also changed from 0 to 1). Then, if someone (the number of people is not limited) needs to take the elevator, that is, to walk into the elevator from outside the elevator, and the first weight value becomes large, the number of times of change of increase and decrease becomes 2.

In some embodiments, in order to avoid a change in weight value caused by elevator jitter or the like as a change in the first weight value, noise reduction processing may be performed on the obtained plurality of first weight values. For example, a curve composed of a plurality of first weight values is filtered by a filter to filter out small-amplitude fluctuations in the curve.

And the shielding frequency determining unit is used for determining the shielding frequency of the elevator light curtain, wherein the shielding frequency is equal to a numerical value obtained after rounding one half of the number of the acquired triggering moments.

In this embodiment, if the number of the trigger times is 2, the shielding frequency of the elevator light curtain is 1, and if the number of the trigger times is 3, the shielding frequency of the elevator light curtain is 1. The shielding times can be calculated in the following mode: and carrying out derivation calculation on a curve consisting of a plurality of first weight values to obtain a derivation curve, wherein the positive and negative change times corresponding to the derivation curve are the shielding times of the elevator light curtain.

And the shielding frequency comparison unit is used for identifying the behavior of shielding the elevator light curtain in the current stop layer as a disturbing behavior if the increase and decrease change frequency is not greater than the shielding frequency.

In the embodiment, the behavior that a person enters or exits the elevator for multiple times can be identified through the method, so that the behavior of disturbing shielding the elevator light curtain can be further screened out.

In some embodiments, the occlusion behavior recognition device 4 further comprises:

and the third weight value obtaining module is used for obtaining a third weight value, and the third weight value is obtained by acquiring the weighing device at the moment when the elevator reaches the current stopping layer.

In this embodiment, in order to facilitate the distinction between the weight values obtained at different times from the above-described embodiments, the elevator stops at the current stopping floor, and the weight value corresponding to the time at which the elevator system obtained from the weighing device stops is referred to as a third weight value.

Correspondingly, the weight value obtaining module 42 is specifically configured to:

if the number of the acquired trigger time is odd within the time period from the time when the elevator reaches the current stop floor to the current time, calculating the shielding duration of the latest shielding behavior according to the current time and the latest acquired trigger time; if the number of the acquired trigger moments is even within a time period from the moment when the elevator reaches the current stop floor to the current moment, calculating the shielding duration of the latest shielding action according to the moment when the newly acquired elevator light curtain finishes being shielded and the moment when the newly acquired elevator light curtain starts being shielded; and if the shielding time length is longer than the preset interval time length, acquiring at least one fourth weight value, wherein each time the shielding time length is equal to an integer multiple of the preset interval time length, the weighing device acquires one fourth weight value.

In this embodiment, only odd number of trigger times are obtained from the time when the elevator reaches the stop floor, that is, the time when the elevator light curtain is completely blocked is not detected in the latest blocking behavior, and if the time from the time when the latest elevator light curtain starts to be blocked to the current time (that is, the latest blocking time) is longer, it indicates that the elevator light curtain is continuously blocked in the latest blocking behavior. Therefore, when the elevator system only obtains odd number of trigger moments, the shielding duration corresponding to the shielding behavior is counted according to the latest obtained one-time moment and the current moment, and when the counted shielding duration is a multiple (such as an integer multiple) of the preset interval duration, the weighing device executes a weight value acquisition action once, that is, the elevator system also obtains each fourth weight value at preset intervals. For example, assuming that the preset interval duration is 10 seconds, when the elevator system acquires only 1 trigger time, when the blocking duration is 10 seconds, 20 seconds, and 30 seconds, respectively, the weighing device acquires and records a fourth weight value, that is, the elevator system acquires a fourth weight value every 10 seconds.

and if the third weight value is equal to any fourth weight value, identifying the behavior of the elevator light curtain in the current stop floor as the tampering behavior.

In this embodiment, if the elevator system determines that the third weight value is not equal to the first obtained fourth weight value, the first obtained fourth weight value is assigned to the third weight value, but after a preset interval duration, a second fourth weight value can be obtained from the weighing device, the third weight value is continuously compared with the second obtained fourth weight value, and if the third weight value is equal to the second obtained fourth weight value, it is determined that the shielding behavior of the current landing floor is a tampering behavior.

In the embodiment of the application, because the weighing device only records a third weight value when the elevator arrives at the stop floor, and the fourth weight value of corresponding quantity is recorded when the shielding time is an integer multiple of the preset interval time, therefore, the weighing device does not need to record excessive weight values, and the memory of the weighing device is effectively saved. In addition, because the fourth weight value can be obtained when the shielding time length meets the correlation between the shielding time length and the preset interval time length, if the elevator system obtains one fourth weight value, the shielding time length is longer, and meanwhile, if the fourth weight value is equal to the third weight value, it is indicated that no goods or personnel enter or exit the elevator in the shielding time length, namely, the elevator light curtain can be accurately identified according to the identification mode, the preset time interval is shielded at least, and no goods or the tampering behavior corresponding to the entering or exiting of the personnel are caused.

In some embodiments, if the number of the acquired trigger times is greater than 1 in the period from the time when the elevator reaches the current stop floor to the current time, the weight value acquiring module 42 further includes:

Specifically, the elevator light curtain generates a trigger signal when detecting that the elevator light curtain is stopped being shielded, and sends the trigger signal to the weighing device, or the elevator light curtain generates a trigger signal when detecting that the elevator light curtain is started being shielded and when the elevator light curtain is stopped being shielded, and sends the trigger signal corresponding to the time when the elevator light curtain is stopped being shielded to the weighing device, and the weighing device collects the weight value of the elevator once again. Or the elevator light curtain sends the trigger signal corresponding to the moment when the shielding is started and the trigger signal corresponding to the moment when the shielding is finished to the weighing device, but the weighing device only collects the weight value of the elevator according to the trigger signal corresponding to the moment when the shielding is finished. Alternatively, the weighing device collects the weight value of the elevator based on the trigger signal corresponding to the time at which the shielding operation is started and the trigger signal corresponding to the time at which the shielding operation is ended, but the elevator system only obtains the weight value (i.e., the fifth weight value) corresponding to the time at which the shielding operation is ended.

Specifically, the comparison of the fifth weight value and the third weight value may be performed in the following manner: one is that the weighing device registers at least two fifth weight values and one third weight value, from which the elevator system acquires the at least two fifth weight values and the third weight value before comparing them. The other is that the weighing device only records two weight values, specifically, the weighing device firstly records a third weight value M, records a fifth weight value N1 when the shielding action is finished (the moment when the elevator light curtain is shielded is finished), compares the M and the N1, and sets a preset number of times X = X-1 (assuming that the original value of X is 2) if M and N1 are equal, namely, currently X =2-1; if M and N1 are not equal, a preset number X =2 is set, and M = N1. And subsequently obtaining a new fifth weight value N2, comparing the N2 with the M, and when X =0 and M is smaller than a preset weight threshold, indicating that the current shielding behavior is that the child shields the elevator light curtain to prevent the elevator from closing the door, namely identifying that the current shielding behavior is a tampering behavior.

In some embodiments, in order to facilitate the manager to know the tampering behavior existing in the elevator in time, the blocking behavior recognition device 4 further includes:

and the scrambling information sending module is used for sending scrambling information to the designated terminal, wherein the scrambling information comprises the identifier of the elevator with the scrambling behavior.

In some embodiments, in order to be able to reduce the impact of tampering behavior on the elevator in time, the shielding behavior identification device 4 further comprises:

and the feedback information receiving module is used for receiving feedback information, and the feedback information comprises voice information or a door closing signal.

In this embodiment, the feedback information may be sent by the designated terminal, or may be sent by other devices. For example, suppose that the elevator system sends the tamper information to a mobile phone of an elevator worker, the elevator worker checks a corresponding monitoring video in a monitoring room of the elevator, and sends feedback information to the elevator system through equipment of the monitoring room, and the elevator system sends specific information to the elevator, for example, if the feedback information includes a door closing signal, the elevator system sends the door closing signal to the elevator, that is, remotely controls the elevator to close the door. If the feedback information comprises voice information, the elevator system sends the voice information to the audio equipment installed on the elevator, so that the audio equipment plays the voice information, and the purpose of remotely reminding a person who sends a disordering behavior is achieved.

and the notification module is used for notifying the weighing device to stop collecting the weight value if the tampering behavior is not identified and the elevator door is closed.
