Embodiment one:

during operation of the elevator, certain actions of the user, called as tampering actions, will disturb the operation of the elevator. Common tamper behavior is: the elevator door (comprising a landing door and a car door) is prevented from closing by the action of the elevator passengers pressing the buttons of each floor at will, continuously shielding the elevator light curtain by hands, feet or other objects, or re-opening the landing door and the car door by using the means in the closing process, and repeating the action in the next closing process so as to prevent the elevator door from closing. In the prior art, only the behavior of invalid calls can be identified, and the behavior of disturbing elevator light curtains cannot be identified.

In order to solve the technical problems, 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 related information of the elevator light curtain and the weighing device, and then whether the elevator has a tampering behavior is judged according to the acquired related information. Specifically, after the elevator system obtains the triggering time of the elevator light curtain (namely, the time when the elevator light curtain starts to be blocked, or the time when the elevator light curtain starts to be blocked and the time when the elevator light curtain ends to be blocked), the elevator system obtains a corresponding weight value from the weighing device according to the obtained triggering time, and finally judges whether the elevator has a disturbing behavior according to the weight value.

Because after the elevator light curtain is shielded, a user usually enters the elevator or leaves the elevator, and the weight value of the elevator can be changed when the user enters or leaves the elevator, the weight value is divided according to the triggering time obtained by the action of shielding the elevator light curtain, and then the tamper is identified according to the weight value obtained by the division, so that the tamper aiming at the elevator light curtain can be effectively identified.

The following describes a shielding behavior recognition method provided by an embodiment of the present application with reference to the accompanying drawings.

Fig. 1 shows a flowchart of a first shielding behavior recognition method according to an embodiment of the present application, where the method is applied to an elevator system, and is described in detail as follows:

step 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 blocked or the time when the elevator light curtain ends to be blocked.

The elevator light curtain is an elevator door safety protection device manufactured according to the photoelectric induction principle, and the working principle is as follows: when the elevator door is from no obstacle to no obstacle, the level detected by the elevator light curtain changes (from 0 to 1), and the subsequent time when the elevator light curtain changes the level is used as the time when the elevator light curtain starts to be blocked and is sent to an elevator system; when there is an obstacle in the elevator door to no obstacle, the level detected by the elevator light curtain also changes (from 1 to 0), and the elevator light curtain sends the time when the level changes to the elevator system as the time when the elevator light curtain is blocked.

In some scenarios, if a user enters and exits the elevator at normal walking speed, the elevator light curtain will detect the moment when it starts to be blocked and the moment when it ends to be blocked in a short time, at which time the elevator system can obtain the moment when the elevator light curtain starts to be blocked in a short time, and the moment when the elevator light curtain ends to be blocked, i.e. the elevator system will obtain 2 trigger moments in a short time. Of course, if a plurality of persons enter and exit the elevator, the elevator system will continuously obtain a plurality of time information (such as the time when a plurality of elevator light curtains start to be blocked, the time when a plurality of elevator light curtains end to be blocked) from the elevator light curtains, that is, obtain a plurality of trigger times.

In some scenarios, if a user traverses a hand or foot in two elevator doors for a long period of time, the elevator light curtain can only determine the moment when the elevator light curtain begins to be blocked in a short time, but cannot determine the moment when the elevator light curtain ends to be blocked. At this time, the elevator system can only acquire the trigger time corresponding to the time when the elevator light curtain starts to be blocked in a short time, namely, 1 trigger time.

In this embodiment, the elevator light curtain can send its obtained trigger moment 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 not started during the operation of the elevator, the triggering time can be obtained only after the elevator reaches the stopping floor, that is, the step S11 includes:

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

The stop floor refers to a floor that can be reached by an elevator, for example, if the floor that can be reached by an elevator a is a floor of a singular floor and the floor that can be reached by an elevator B is a floor of a double floor, then the floors of the singular floors such as floor 3, floor 5, and floor 7 are all floors that can be reached by an elevator a, and the floors of the double floors such as floor 2, floor 4, and floor 6 are all floors that can be reached by an elevator B. If the current stopping floor of the elevator A is floor 3, the current stopping floor corresponding to the elevator A is floor 3.

In the embodiment, the elevator is considered to stop at only one floor at a time, so that the triggering time of the current stopping layer is only acquired, and the follow-up accurate analysis of the shielding behavior of the current stopping layer is facilitated.

And step S12, acquiring the weight value of the elevator acquired by the weighing device based on the triggering moment.

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

In this embodiment the weight value acquired by the elevator system is related to the triggering moment acquired, which is related to the behavior of the elevator light curtain that starts to be blocked and ends to be blocked, i.e. to the blocking of the elevator light curtain. Because the user enters and exits the elevator and needs to pass through the elevator door, the user enters and exits the elevator and can be detected by the elevator light curtain, and the weight of the elevator is generally changed after the user enters and exits the elevator, namely, the corresponding weight value is obtained according to the obtained triggering time, so that the user can obtain more accurate identification results later.

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

Of course, if the memory of the weighing device is relatively large, the weighing device may record the weight value over a relatively long period of time (e.g., the last 10 minutes), which is not limited herein.

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

In this embodiment, whether the behavior of shielding the elevator light curtain corresponding to the obtained weight value is a tamper behavior is determined by analyzing whether the characteristics of the obtained weight value conform to the characteristic rules of the weight values corresponding to various tamper behaviors. Wherein, the characteristic rule of the weight value corresponding to various tamper behaviors can be determined by the following modes: curve fitting the weight values corresponding to the various tamper behaviors, or analyzing the weight values, and the like.

In the embodiment of the application, the triggering time is the time when the elevator light curtain starts to be blocked, or the time when the elevator light curtain ends to be blocked, namely, when the elevator system acquires the triggering time, the blocking behavior of the elevator light curtain is indicated, so that when the weight value of the elevator is acquired according to the acquired triggering time, only the weight value corresponding to the blocking behavior is acquired, and when the tamper behavior is identified according to the acquired weight value, the tamper behavior aiming at the elevator light curtain can be effectively identified, thereby improving the accuracy of identification.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.

Embodiment two:

fig. 2 shows a flowchart of a second method for identifying shielding behavior according to an embodiment of the present application, where step S21 of the present embodiment is used for defining step S11 of the first embodiment, step S22 and step S23 are used for defining step S12 of the first embodiment, step S24 is used for defining step S13 of the first embodiment, and the details are as follows:

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

In some embodiments, the step S21 includes:

The stopping layer refers to a floor which can be reached by the elevator, and the current stopping layer refers to a floor which the elevator stops currently.

Step S22, if the number of the triggering times is odd in the period from the time when the elevator reaches the current stopping layer to the current time, calculating the shielding duration of the latest shielding action according to the current time and the latest acquired triggering time; if the number of the acquired triggering moments is even in the period from the moment when the elevator reaches the current stopping layer to the current moment, calculating the shielding duration of the latest shielding action according to the moment when the latest acquired elevator light curtain is blocked and the moment when the latest acquired elevator light curtain starts to be blocked.

In this embodiment, if the elevator system obtains an odd number of trigger moments from the elevator light curtain from the moment of stopping the elevator to the current moment, it indicates that in the latest shielding action, the elevator light curtain only detects that the elevator light curtain starts to be shielded, but does not detect that the elevator light curtain ends to be shielded (only a rising edge occurs and does not have a falling edge), that is, the latest shielding action may be a disturbance action of deliberately shielding the elevator light curtain by a user's hand, foot, etc., and then, the shielding duration of the elevator light curtain to be shielded is calculated according to the latest obtained trigger moment and the current moment. For example, assuming that the latest acquired trigger time (i.e., the time when the elevator light curtain has been recently started to be blocked) is 7 points 06 minutes 1 second and the current time is 7 points 07 minutes 5 seconds, the blocking time when the elevator light curtain is blocked is 1 minute 4 seconds.

Of course, if the number of the acquired trigger moments is even in the 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 is blocked, or the last blocking action is finished and no new blocking action is generated, at this time, the blocking duration of the last blocking action is calculated according to the moment when the elevator light curtain is blocked and the moment when the elevator light curtain is blocked.

Step S23, if the shielding time length is greater than a preset time length threshold value, at least two first weight values in the shielding time length are obtained, wherein the first weight values are acquired by the weighing device at a preset frequency.

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

In this embodiment, only a limited number of weight values are stored after the weighing device has acquired the weight value of the elevator at a preset frequency, considering the limited memory of the weighing device. For example, assuming that the weighing device stores only 2 weight values, a1 and a2, a1 being the larger weight value and a2 being the smaller weight value, after detecting a new weight value, comparing the new weight value with a1 and a2, respectively, if the new weight value is greater than a1, assigning the new weight value to a1, if the new weight value is less than a2, assigning the new weight value to a2, otherwise discarding the new weight value. Of course, if the weighing device stores only 2 weight values, the subsequent elevator system can only obtain 2 weight values from the weighing device.

And step S24, if the first weight values are equal, identifying the action of shielding the elevator light curtain in the current stopping layer as a tamper action.

In this embodiment, if the obtained first weight values are equal, for example, if a1 and a2 are equal, it indicates that no cargo and no personnel enter or exit the elevator, that is, the user deliberately blocks the elevator light curtain, and at this time, it is determined that the blocking behavior is a tamper behavior.

In the embodiment of the application, since the acquired trigger time is the trigger time of the elevator in the period from the time of reaching the current stopping floor to the current time, the acquired trigger time of the elevator system is indicated to accurately reflect whether the elevator is blocked at the current stopping floor, and since at least two weight values (namely first weight values) obtained from the weighing device are equal when the blocking time is longer, no goods or people enter or exit the elevator in the time period when the elevator light curtain is blocked, otherwise, the first weight values obtained from the weighing device cannot be equal, namely, whether the blocking behavior is a tamper behavior can be accurately identified through the mode.

In some embodiments, if the number of acquired trigger moments is greater than 1, the shielding duration is not greater than a preset duration threshold, and each trigger moment 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 the second weight value, in a period from the moment that the elevator reaches the current stopping floor to the current moment, the step S12 includes:

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

Correspondingly, the step S13 includes:

if the second weight values are equal and the second weight value is smaller than a preset weight threshold value, the behavior of shielding the elevator light curtain in the current stopping layer is identified as a tamper behavior.

The preset weight threshold is a weight value corresponding to the child, 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 there is at least a time when one elevator light curtain starts to be blocked and a time when at least one elevator light curtain ends to be blocked in these trigger times. Each elevator light curtain starts the moment of being sheltered from and all generates a trigger signal to each elevator light curtain finishes the moment of being sheltered from, and these trigger signals will send to weighing device, and every time this weighing device receives a trigger signal, this weighing device all carries out the collection action of a weight value to the elevator.

In this embodiment, after at least two adjacent trigger moments are acquired, the elevator system will acquire adjacent second weight values corresponding to these trigger moments from the weighing device, e.g. the same number of trigger moments, wherein the two adjacent second weight values are acquired by triggering the weighing device by two adjacent trigger signals. The second weight values acquired by the elevator system are equal, so that no goods or people enter or exit in the time period where the adjacent trigger moments are located, and the current shielding behavior is indicated to be the behavior that the children repeatedly shield the elevator light curtain in a large probability because the second weight values are smaller than the preset weight threshold. That is, according to the above-described identification method, the behavior of the tamper repeatedly blocking the light curtain of the elevator can be accurately identified.

Of course, the elevator system may also acquire only the second weight value corresponding to the second preset number (the second preset number may be 3) of trigger times acquired recently from the weighing device after acquiring the first preset number (the first preset number may be 5) of trigger times. Since the tamper behavior is usually the behavior of shielding the elevator light curtain for a plurality of times, after the first preset number of trigger moments are acquired, only the second weight values corresponding to the second preset number of trigger moments acquired recently are analyzed, so that the accuracy of the recognition 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, the behavior of shielding the elevator light curtain in the current stopping layer is recognized 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 larger than 1, and the second preset multiple is smaller than 1.

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

In this embodiment, when the detected weight values at different moments are different, it is possible that the elevator riding person jumps in the car or runs in the car, and these actions result in the weight values detected by the weighing device having a specific relationship. For example, let a1 be the maximum weight value, a2 be the minimum weight value, and two second weight values b1 and b2 are selected, respectively, and b1 is greater than b2. If the elevator system determines that a1 is greater than b1 by 150% and a2 is less than b2 by 50%, then the elevator is determined to have jumping or running behavior, i.e. the behavior of shielding the elevator light curtain is determined to be a tampering behavior.

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

In some embodiments, considering that the tamper behavior may also be a behavior corresponding to the same elevator occupant moving in and out of the elevator, the weighing device may analyze the first weight value acquired by the frequency of the budget to determine whether the shielding behavior is a behavior corresponding to the same elevator occupant moving in and out of the elevator. At this time, step S13 includes:

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

In this embodiment, assuming that after the elevator is stopped at one floor, 2 passengers are continuously moved out of the elevator so that the first weight value becomes smaller, the number of increase/decrease changes is changed from 0 to 1 (if only 1 passenger is moved out of the elevator, the number of increase/decrease changes is also changed from 0 to 1). Then, if a person (the number of persons is not limited) needs to take the elevator, that is, walk from outside the elevator into the elevator, so that the first weight value becomes large, the number of increase/decrease changes becomes 2.

In some embodiments, in order to avoid a change in the weight value caused by elevator shake or the like as a change in the first weight value, the obtained plurality of first weight values may be subjected to noise reduction processing first. For example, a curve composed of a plurality of first weight values is subjected to a filter process using 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 trigger times is 2, the number of times of shielding the elevator light curtain is 1, and if the number of trigger times is 3, the number of times of shielding the elevator light curtain is 1. Wherein, the shielding times can be calculated by the following ways: and carrying out derivative calculation on a curve formed by a plurality of first weight values to obtain a derivative curve, wherein the positive and negative change times corresponding to the derivative curve are the shielding times of the elevator light curtain.

And B3, if the increasing and decreasing change times are not greater than the shielding times, identifying the behavior of shielding the elevator light curtain in the current stopping layer as a disturbing behavior.

In this embodiment, since the behavior of a person entering and exiting the elevator multiple times can be identified by the above method, the behavior of disturbing the light curtain of the elevator can be further screened out.

Embodiment III:

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

step S31, obtaining a third weight value, wherein the third weight value is obtained by collecting the weighing device at the moment when the elevator reaches the current stopping floor.

In this embodiment, in order to facilitate distinguishing from the weight values acquired at different times in the above-described embodiment, the elevator is stopped at the current stop floor, and the weight value acquired by the elevator system from the weighing device corresponding to the time of stopping is referred to as a third weight value.

In some embodiments, in order to reduce the occupation of the memory of the weighing device by the recorded weight values, the weighing device only acquires the weight values of the elevator at a specific moment, such as only recording a third weight value after the elevator has stopped at the current stop floor, the elevator system again acquiring its recorded third weight value from the weighing device.

In this embodiment, since only one third weight value is recorded, it is unnecessary to occupy more memory of the weighing device.

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 triggering times is an odd number in the period from the time when the elevator reaches the current stopping layer to the current time, calculating the shielding duration of the latest shielding action according to the current time and the latest acquired triggering time; if the number of the acquired triggering moments is even in the period from the moment when the elevator reaches the current stopping layer to the current moment, calculating the shielding duration of the latest shielding action according to the moment when the latest acquired elevator light curtain is blocked and the moment when the latest acquired elevator light curtain starts to be blocked.

Step S34, if the shielding time period is longer than the preset interval time period, at least one fourth weight value is obtained, wherein the weighing device acquires the fourth weight value every time the shielding time period is equal to an integer multiple of the preset interval time period.

In this embodiment, if only an odd number of trigger times are obtained from the time when the elevator arrives at the stop floor, that is, the time when the elevator light curtain ends to be blocked is not detected in the latest blocking action, if the time from the latest time when the 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 action. Therefore, when the elevator system only acquires the odd trigger time, the shielding time length corresponding to the shielding behavior is counted according to the latest acquired trigger time and the current time, and when the counted shielding time length is a multiple (such as an integer multiple) of the preset interval time length, the weighing device executes the acquisition action of one time of the weight values, namely, the elevator system acquires each fourth weight value at preset intervals. For example, assuming that the preset interval duration is 10 seconds, in case the elevator system only acquires 1 trigger moment, when the occlusion duration is 10 seconds, 20 seconds, 30 seconds, respectively.

And step S35, if the third weight value is equal to any one of the fourth weight values, the action of shielding the elevator light curtain in the current stopping layer is identified as a disturbing action.

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 period, the elevator system can also obtain the second fourth weight value from the weighing device, then the elevator system continues to compare the third weight value with the second obtained fourth weight value, and if the third weight value is equal to the second obtained fourth weight value, then the current parking layer shielding behavior is determined to be a tamper behavior.

In the embodiment of the application, the weighing device records the third weight value only when the elevator reaches the stop layer, and records the fourth weight value of the corresponding quantity each time when the shielding time length is an integer multiple of the preset interval time length, so that the weighing device does not need to record excessive weight values, and the memory of the weighing device is effectively saved. In addition, the fourth weight value can be obtained when the shielding duration meets the correlation between the shielding duration and the preset interval duration, so that if the elevator system obtains the fourth weight value, the shielding duration is longer, and meanwhile, if the fourth weight value is equal to the third weight value, no goods or personnel enter or exit the elevator within the shielding duration, that is, the elevator light curtain can be accurately identified according to the identification mode to at least shield the preset time interval, and no tamper corresponding to the goods or personnel entering or exiting the elevator exists.

In some embodiments, if the number of acquired trigger moments is greater than 1 and the shielding duration is not greater than the preset interval duration in a period from the time when the elevator reaches the current stopping 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 the end of the shielding is detected and sends the trigger signal to the weighing device, or the elevator light curtain generates a trigger signal when the end of the shielding is detected and sends only the trigger signal corresponding to the end of the shielding to the weighing device, and the weighing device acquires the weight value of the elevator once again. Or the elevator light curtain sends the trigger signal corresponding to the moment of beginning to be blocked and the trigger signal corresponding to the moment of ending to be blocked 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 of ending to be blocked. Or, the weighing device collects the weight value of the elevator according to the trigger signal corresponding to the moment when the shielding starts, and also collects the weight value of the elevator according to the trigger signal corresponding to the moment when the shielding ends, but the elevator system only obtains the weight value (namely, the fifth weight value) corresponding to the moment when the shielding ends.

Since the weighing device has obtained a third weight value when the elevator stops, and the weight value of the elevator may not have changed when the shielding action is just generated (i.e. the moment when the elevator light curtain starts to be shielded), the elevator system only obtains the weight value corresponding to the moment when the elevator light curtain is blocked (i.e. the fifth weight value) in consideration of the comparison of the fifth weight value obtained by the subsequent direct use with the third weight value, and the accuracy of the subsequent recognition result can be improved.

Correspondingly, the step S13 includes:

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

Specifically, the comparison of the fifth weight value with the third weight value may be in the following manner: one is that the weighing device records at least two fifth weight values and one third weight value, from which the elevator system obtains and compares. 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 blocked), compares the M with the N1, and if M and N1 are equal, sets a preset times X=X-1 (assuming that the original value of X is 2), namely the current X=2-1; if M and N1 are not equal, the preset number of times x=2 is set, so that m=n1. And then obtaining a new fifth weight value N2, comparing the N2 with M, and when X=0 and M is smaller than a preset weight threshold value, indicating that the current shielding behavior is that the child shields the elevator light curtain so as to prevent the elevator from closing the door, namely identifying that the current shielding behavior is a tamper behavior.

In this embodiment, since the third weight value is the weight value corresponding to the elevator when the elevator stops, and the fifth weight value is the weight value corresponding to the moment when the shielding behavior ends, by comparing the third weight value and the fifth weight value, it can be determined whether there is a load or a person entering or exiting the elevator during the shielding behavior, if there is no load or person entering or exiting the elevator, and it is determined that the third weight value is smaller, it indicates that the current child shields the elevator light curtain in the elevator for multiple times, so that the current shielding behavior can be accurately identified as the tamper behavior. In addition, the weighing device only needs to record a limited weight value, so that the memory required by the weighing device can be effectively saved.

In some embodiments, to facilitate the manager to timely learn about the tamper behavior of the elevator, after identifying the tamper behavior, the method further includes:

the tamper information is transmitted to the specified terminal, the tamper information containing an identification of the elevator in which the tamper activity is present.

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, etc. Because appointed terminal can receive the disorder signal after, can acquire the sign of elevator from this disorder information, and then look over the condition of corresponding elevator according to the sign of this elevator, consequently, elevator system sends the disorder information for appointed terminal, is favorable to the manager in time to follow up the disorder action that the elevator exists, and then selects further operation to can improve the security of elevator.

In some embodiments, in order to be able to reduce in time the impact of the tampering act on the elevator, after the above-mentioned sending of the tampering information to the designated terminal, it comprises:

feedback information is received, the feedback information including voice information or a door closing signal.

In this embodiment, the feedback information may be sent by the above-mentioned designated terminal, or may be sent by another device. For example, assume that an elevator system sends tamper information to the mobile phone of an elevator worker who checks the corresponding monitoring video in the monitoring room of the elevator, and then sends feedback information to the elevator system via the equipment of the monitoring room, which in turn sends specific information to the elevator, e.g. if the feedback information comprises a door closing signal, the elevator system sends the door closing signal to the elevator, i.e. remotely controlling the door closing of the elevator. If the feedback information comprises voice information, the elevator system sends the voice information to audio equipment arranged on the elevator so that the audio equipment plays the voice information, and the purpose of remotely reminding people who send out the tamper behavior is achieved.

In some embodiments, further comprising:

if no tamper is identified and the elevator door is closed, the weighing device is informed to stop the collection of the weight value.

In this embodiment, if the elevator system determines that the current shielding behavior is not a tamper behavior according to the obtained weight value, and determines that the elevator door is closed, for example, the landing door of the elevator is closed, and the weight value of the elevator is not changed after the elevator door is closed, the weighing device pauses to collect the weight value, so that the resources of the weighing device can be effectively saved. Waiting until the elevator reaches a new stopping floor to start collection, or collecting again after the elevator light curtain is blocked.

Embodiment four:

corresponding to the shielding behavior recognition methods of the first, second and third embodiments, fig. 4 shows a block diagram of the shielding behavior recognition apparatus according to the embodiment of the present application, and for convenience of explanation, only the portions related to the embodiment of the present application are shown.

The shielding behavior recognition device 4 is applied to an elevator system, and includes: a trigger time acquisition module 41, a weight value acquisition module 42, and an occlusion behavior recognition module 43, wherein:

The trigger time obtaining module 41 is configured to obtain a trigger time of an elevator light curtain, where the trigger time is a time when the elevator light curtain starts to be blocked, or is a time when the elevator light curtain ends to be blocked.

In some embodiments, considering that the elevator light curtain is usually started after the elevator reaches the stopping floor and not started during the operation of the elevator, the triggering time can be obtained only after the elevator reaches the stopping floor, namely the triggering time obtaining module 41 is specifically used for:

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

And the shielding behavior recognition module 43 is used for recognizing whether the behavior shielding the elevator light curtain is a tampering behavior according to the weight value.

In some embodiments, the weight value acquisition module 42 includes: and the shielding duration calculation unit and the first weight value acquisition unit. Wherein:

the shielding duration calculation unit is used for calculating the shielding duration of the latest shielding action according to the current moment and the latest acquired triggering moment if the number of the acquired triggering moments is an odd number in the period from the moment that the elevator reaches the current stop layer to the current moment; if the number of the acquired triggering moments is even in the period from the moment when the elevator reaches the current stopping layer to the current moment, calculating the shielding duration of the latest shielding action according to the moment when the latest acquired elevator light curtain is blocked and the moment when the latest acquired elevator light curtain starts to be blocked.

The shielding duration here refers to the shielding duration of the elevator light curtain which is shielded once.

In this embodiment, if the elevator system only obtains the odd number of trigger moments from the elevator light curtain from the moment of stopping the elevator to the current moment, it indicates that in the latest shielding action, the elevator light curtain only detects that the elevator light curtain starts to be shielded, but does not detect that the elevator light curtain ends to be shielded (only the rising edge occurs, but there is no falling edge), that is, the near primary shielding action may be a disturbance action of deliberately shielding the elevator light curtain by a user's hand, foot, etc., and then, the shielding duration of the elevator light curtain is calculated according to the latest obtained trigger moment and the current moment. For example, assuming that the latest acquired trigger time (i.e., the time when the elevator light curtain has been recently started to be blocked) is 7 points 06 minutes 1 second and the current time is 7 points 07 minutes 5 seconds, the blocking time when the elevator light curtain is blocked is 1 minute 4 seconds.

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

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

if the first weight values are equal, the behavior of shielding the elevator light curtain in the current stopping layer is identified as a tamper behavior.

In some embodiments, if the number of acquired triggering times is greater than 1, the shielding time is not greater than a preset time threshold, and each triggering time generates a triggering signal, where the triggering 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 shielding behavior recognition module 43 is specifically configured to:

In some embodiments, the above-mentioned shielding behavior recognition module 43 is further configured to:

if the second weight values are not equal, selecting two adjacent second weight values 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 smaller than a second preset multiple of a smaller value of the two selected second weight values, the behavior of shielding the elevator light curtain in the current stopping layer is recognized as a tamper 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 greater than 1, and the second preset multiple is smaller than 1.

In some embodiments, considering that the tamper behavior may also be a behavior corresponding to the same elevator occupant moving in and out of the elevator, the weighing device may analyze the first weight value acquired by the frequency of the budget to determine whether the shielding behavior is a behavior corresponding to the same elevator occupant moving in and out of the elevator. At this time, the shielding behavior recognition module 43 includes:

and an increasing/decreasing number of times determining unit configured to determine the increasing/decreasing number of times based on the plurality of first weight values, wherein if the first weight value changes from small to large or the first weight value changes from large to small, the increasing/decreasing number of times is increased by 1.

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 by rounding half of the acquired triggering time.

And the shielding frequency comparison unit is used for identifying the behavior of shielding the elevator light curtain in the current stopping layer as a tamper behavior if the increasing and decreasing variation frequency is not greater than the shielding frequency.

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

and the third weight value acquisition module is used for 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 stopping layer.

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

if the number of the acquired triggering times is an odd number in the period from the time when the elevator reaches the current stopping layer to the current time, calculating the shielding duration of the latest shielding behavior according to the current time and the latest acquired triggering time; if the number of the acquired triggering moments is even in the period from the moment when the elevator reaches the current stopping layer to the current moment, calculating the shielding duration of the latest shielding action according to the moment when the latest acquired elevator light curtain is blocked and the moment when the latest acquired elevator light curtain starts to be blocked; if the shielding time period is longer than the preset interval time period, at least one fourth weight value is obtained, wherein the weighing device acquires the fourth weight value every time the shielding time period is equal to an integer multiple of the preset interval time period.

In this embodiment, if only an odd number of trigger times are obtained from the time when the elevator arrives at the stop floor, that is, the time when the elevator light curtain ends to be blocked is not detected in the latest blocking action, if the time from the latest time when the 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 action. Therefore, when the elevator system only acquires the odd trigger time, the shielding time length corresponding to the shielding behavior is counted according to the latest acquired primary time and the current time, and when the counted shielding time length is a multiple (such as an integer multiple) of the preset interval time length, the weighing device executes the acquisition action of one time of the weight values, namely, the elevator system acquires each fourth weight value at preset intervals. For example, assuming that the preset interval duration is 10 seconds, in case the elevator system only acquires 1 trigger moment, when the occlusion duration is 10 seconds, 20 seconds, 30 seconds, respectively.

if the third weight value is equal to any one of the fourth weight values, the behavior of shielding the elevator light curtain in the current stopping layer is identified as a tamper behavior.

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

In some embodiments, in order to facilitate the manager to know in time the tampering behaviour present in the elevator, the screening behaviour identifying means 4 further comprise:

and the tamper information sending module is used for sending tamper information to the appointed terminal, wherein the tamper information comprises the identification of the elevator with tamper behavior.

In some embodiments, in order to be able to reduce in time the impact of the tampering behaviour on the elevator, the screening behaviour identifying means 4 further comprises:

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

And the notification module is used for notifying the weighing device to stop collecting the weight value if no tamper behavior is recognized and the elevator door is closed.

It should be noted that, because the content of information interaction and execution process between the above devices/units is based on the same concept as the method embodiment of the present application, specific functions and technical effects thereof may be referred to in the method embodiment section, and will not be described herein.
