Description
Technical Field
The invention relates to elevator control, in particular to a control processing method of an elevator running mode.
Background
In the actual use process of the elevator, the regular traveling of passengers often makes the operation of the elevator present certain regularity, which can be called as a habit of taking the elevator, for example, every working day is about 7 o' clock in the morning, the elevator can respond to the elevator taking request of a certain passenger and stop at a certain floor, the passenger enters the car and then moves to a bottom floor hall and then opens the car door, and the passenger leaves the elevator. For the identification of such elevator riding habits, reference is made to the invention patent application with application number 201910449301.5. For this application scenario, the existing elevator generally operates from its current location to the floor where the passenger is located after receiving the passenger's elevator-taking request signal. In view of the foregoing manner of response, passengers need to wait for a certain amount of time before entering the car in order for the elevator car to travel from its current location to the passenger's floor, which increases the waiting time of the passengers undoubtedly.
In order to solve the above-mentioned passenger waiting problem, chinese patent invention No. CN104150291B proposes to match the current time with the historical operating time of the elevator, and when the matching is successful, control the elevator to move to the corresponding floor for waiting for a call, thereby shortening the waiting time of the passenger.
In the implementation mode provided by the patent, when an external call signal is not received within the preset waiting time, the elevator matches the current date and time with the operation database through the matching rule, if the current date and time are matched with the corresponding floor, the elevator operates to the corresponding floor to wait for the call, and if the current date and time are not matched with the corresponding floor, the elevator operates to the initial floor to wait for the call, so that the control of waiting for the elevator is realized. However, the above-mentioned processing method has the following disadvantages:
a. although there is no external call within the preset waiting time, the preset waiting time may be a busy stage of the elevator, such as a certain time before the peak time of an office building, and this situation is not suitable for starting the waiting elevator-taking control mode;
b. the elevator matches the current date and time with the operation database every time, the calculation amount is large, and the requirement on hardware capability is high.
In view of the above, it is a technical problem to correct the passenger's elevator riding habits and to ensure that different elevator operation modes are started at appropriate times to overcome the above-mentioned drawbacks.
Disclosure of Invention
The invention aims to provide a control processing method of an elevator running mode, which can solve the problems that the elevator in the prior art improperly enters a waiting elevator running mode before a busy stage to influence the elevator riding experience of passengers and the processing process of the elevator running mode consumes a large amount of calculation.

2, setting that the time interval between the current starting time and the finishing time of the previous operation cycle of the elevator in a time interval does not exceed a time threshold;
and 3, the elevator riding habit model with centralized trend parameters in the set time period exists.
Further, in the starting condition of the waiting elevator-taking running mode, when only the last condition is not met, self-learning is carried out according to the elevator running data, if an elevator-taking habit model is obtained, the waiting elevator-taking running mode is entered, and otherwise, the conventional running mode is still kept; and when the rest conditions are not met, maintaining the normal operation mode.
The elevator operation cycle refers to the process from the departure floor to the stop floor of the elevator car, and the operation cycle threshold is set according to the probability that a passenger taking request signal taking a non-waiting floor as an elevator taking floor appears in the elevator waiting passenger taking period and/or an elevator taking request signal taking the elevator taking time corresponding to the non-elevator taking habit as the elevator taking time appears in the elevator waiting passenger taking period.
The time threshold is set according to the probability that the passenger taking request signal taking the non-waiting floor as the elevator taking floor occurs in the elevator waiting passenger taking period and/or the passenger taking request signal taking the elevator time corresponding to the non-elevator taking habit as the elevator taking time occurs in the elevator waiting passenger taking period.
Wherein further the time interval is an average interval of at least two time intervals between the moment of elevator start and the moment of completion of the previous run cycle.
In the above method, the specific steps of step 3 are as follows:

Preferably, the selection method of the elevator is: the n elevator taking habits are sorted according to the sequence of the elevator taking times, m elevators are selected from back to front, and when m is larger than 1, one elevator is selected optionally or according to a traditional allocation algorithm, wherein n is a natural number larger than 1, m is a natural number and m is larger than or equal to 1 and is smaller than n.
Further, in step a2, when the boarding timing of the passenger matches the boarding habit, the boarding request signal is automatically registered for the passenger according to the boarding habit.
Preferably, the automatically registered ride request signal is confirmed or modified by the passenger.
Preferably, the relevant indication button is also lighted at the same time as the automatic registration of the boarding request signal.
In the above method, in step a1 and step a2, when the boarding habit is not met at the boarding floor or the boarding timing of the passenger, the boarding habit is identified based on the number of occurrences and distribution of boarding requests that do not meet the boarding habit.
Preferably, the elevator riding habit is identified according to the following steps:
step S1, judging whether the self-learning elevator-taking habit needs to be re-learned, if so, turning to step S2, otherwise, switching to a conventional operation mode;

Detailed Description
In the existing elevator system, an external call signal is not received within a preset waiting time, the elevator automatically matches the current date and time with an operation database through a matching rule, if the current date and time are matched with a corresponding floor, the elevator operates to the corresponding floor to wait for calling (automatically enters a mode of waiting for passengers to ride the elevator), and if the current date and time are not matched with the corresponding floor, the elevator operates to an initial floor to wait for calling, so that the control of waiting for riding the elevator is realized. However, sometimes (for example, a certain time before the peak time of an office building) although there is no external call within the preset waiting time, the elevator is likely to need to be busy after the preset waiting time, and the mode is not suitable for entering the mode of waiting for passengers to take the elevator, and the computation amount of the control mode is large, and the requirement on the elevator is high.
In view of the above, it is a technical problem to correct the passenger's elevator riding habits and to ensure that different elevator operation modes are started at appropriate times to overcome the above-mentioned drawbacks.
The invention relates to a control processing method of an elevator operation mode, wherein the elevator operation mode comprises a normal operation mode and a waiting elevator operation mode, and the control processing method comprises the following steps:
step 1, judging the state of the elevator in a conventional operation mode according to elevator operation data, if the starting condition of the waiting elevator operation mode is met, turning to step 2, otherwise, still maintaining the conventional operation mode;
step 2, the elevator enters the waiting elevator taking operation mode and waits for the elevator taking floor corresponding to the elevator taking habit corresponding to the elevator taking moment closest to the current moment in the elevator taking habit model;
and 3, responding to the passenger taking elevator request according to the passenger taking elevator habit model and the passenger taking elevator request signal after receiving the passenger taking elevator request signal.
In step 1, the starting condition of the waiting elevator-taking operation mode may be any one of the following three cases:
1) the method comprises the following steps that two conditions are simultaneously met, wherein the condition 1 is that the number of operation cycles of an elevator in a set time interval does not exceed an operation cycle threshold value, and the condition 2 is that the elevator riding habit model with centralized trend parameters in the set time interval exists;
2) the method comprises the following steps that two conditions are simultaneously met, wherein the condition 1 is that the time interval between the current starting time and the finishing time of the previous running cycle of the elevator in a set time interval does not exceed a time threshold, and the condition 2 is that the elevator riding habit model with centralized trend parameters in the set time interval exists;
3) and three conditions are simultaneously met, wherein the condition 1 is that the number of the operation cycles of the elevator in a set time interval does not exceed an operation cycle threshold, the condition 2 is that the time interval between the current starting time and the finishing time of the previous operation cycle of the elevator in the set time interval does not exceed a time threshold, and the condition 3 is that the elevator riding habit model with centralized trend parameters in the set time interval exists.
In three conditions of starting conditions of the waiting elevator-taking operation mode, when only the last condition is not met (namely, the elevator-taking habit model with centralized parameters in the set time interval does not exist), self-learning is carried out according to elevator operation data, if the elevator-taking habit model is obtained, the waiting elevator-taking operation mode is entered, and otherwise, the conventional operation mode is still kept; and when the rest conditions are not met, maintaining the normal operation mode.
The elevator operation cycle refers to the process from the departure floor to the stop floor of the elevator car, the operation cycle threshold is set according to the probability that an elevator taking request signal taking a non-waiting floor as an elevator taking floor occurs in the elevator waiting period of the elevator and/or an elevator taking request signal taking the elevator taking time corresponding to the non-elevator taking habit as the elevator taking time occurs in the elevator waiting period of the elevator, the set time period is usually not too long, the situation that a local busy time period is included is avoided, and usually several minutes are taken as the best choice.
The time threshold is set according to the probability that an elevator taking request signal with a non-waiting floor as an elevator taking floor occurs during the elevator taking of the waiting passenger and/or an elevator taking request signal with an elevator taking time corresponding to a non-elevator taking habit as an elevator taking time occurs during the elevator taking of the waiting passenger, and the time interval is preferably an average interval (of course, a minimum interval) of at least two time intervals between the elevator starting time and the previous operation cycle completion time.
In step 1, the time for determining the starting condition of the waiting elevator taking operation mode may be set according to actual conditions, and it is not necessarily determined whether the starting condition is satisfied after each data update, for example, the time may be set at regular intervals or every time a certain number of elevator taking request signals are received. When the starting condition of the waiting elevator-taking operation mode is not judged, the last judgment result is used. Of course, the first operation requires a judgment because there is no judgment result.
In step 2, the elevator riding habit model is a model for describing elevator riding habits of passengers and predicting future elevator riding requests of the passengers, the elevator riding habits are general terms of rules of the elevator riding behaviors of the passengers which are periodically repeated, and one elevator riding habit refers to rules of a group of passengers which have the same periodic repetition. The elevator taking behavior at least comprises the elevator taking time and elevator taking floors of passengers, or also comprises the traveling direction and/or elevator taking times; the rule means that the taking times of the taking behaviors have certain time distribution characteristics, and other components of the taking behaviors with the same time distribution characteristics except the taking times are the same or have group characteristics.
The elevator taking behavior is characterized in that the distribution of at least one elevator taking floor on the elevator taking time has at least one peak area. In the patent application with reference to application No. 201910449301.5 entitled "method for identifying elevator passenger riding habits", the output information of the elevator riding habit model at least includes the occurrence time of the passenger riding needs and the passenger riding floors corresponding to the occurrence time, and may also include at least one of statistical parameters (central tendency parameter and discrete tendency parameter) corresponding to the riding behaviors. The input of the elevator taking habit model at least comprises a central tendency parameter (used for determining the occurrence time of the elevator taking behavior in the elevator taking behavior occurrence period) in the statistical parameters of the elevator taking behavior time distribution of passengers.
Specifically, the riding habit is expressed as a probability density curve, and the probability density curve may be in any shape as long as a certain specific region exists therein, and the probability density corresponding to the specific region is significantly larger than the probability density corresponding to a region adjacent to the specific region and different from the specific region. If the probability density corresponding to the specific area is significantly larger than that corresponding to the adjacent area, the specific area is called a peak area, and if the probability density of the peak area is a typical area, the specific area is called a typical distribution.
Other advantages and effects of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein it is shown in the accompanying drawings, wherein the specific embodiments are by way of illustration. In the following description, specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced or applied in different embodiments, and the details may be based on different viewpoints and applications, and may be widely spread and replaced by those skilled in the art without departing from the spirit of the present invention.

In step a3, the time interval between the boarding time and the current time in the boarding habit corresponding to the boarding floor where the elevator selected in the mode 2 is located is greater than or equal to the time taken by the elevator to respond to the boarding request of the passenger and return to the original waiting floor, so that there is enough time for the selected elevator to respond to the boarding request of the passenger and return to the original waiting floor.

Preferably, the above conventional allocation algorithm may use the shortest moving distance or time of the elevator car as a measure, and may also use energy saving as a measure.

Further, the registration result may be displayed statically (in any one of different sizes, fonts, patterns, colors, or the like or in a combination thereof) or dynamically (in size conversion, color conversion, luminance change, blinking, or the like), and may be transmitted to the passenger's mobile device, displayed on a display device at a landing, or displayed on a landing registration button, a destination floor registration and display device, or the like. The passenger may make modifications to the check-in results, such as: the modification information is entered using the input device of the passenger's mobile device and transmitted by the mobile device to the elevator.

Specifically, in step a1 and step a2, when the determination result is negative, the elevator boarding habit is identified as follows:
step S1, judging whether the self-learning elevator-taking habit needs to be re-learned, if so, turning to step S2, otherwise, switching to a conventional operation mode;
and step S2, relearning the elevator taking habit, if a new elevator taking habit model is obtained, saving the new elevator taking habit model and keeping a waiting elevator taking operation mode, otherwise, switching to a conventional operation mode.
In step S1, the condition that the boarding habit needs to be learned again is that at least one of the boarding timing and the boarding floors of the boarding request signal for n consecutive times does not conform to the boarding habit, or both the boarding timing and the boarding floors conform to the boarding habit but the correspondence relationship therebetween does not conform to the boarding habit and n exceeds a set threshold, where n is a natural number greater than 1.
In step S1, if it is not necessary to learn the boarding habit again, the waiting elevator waiting for passengers to board at the boarding floor according to the boarding habit model is switched to the normal operation mode and does not wait any more, and the waiting boarding operation mode is resumed after the boarding habit of passengers is met again at the boarding time, where n is a natural number greater than 1.
Example four
The present embodiment adds the functions of automatic registration and confirmation and modification of the registration result to the third embodiment, as shown in fig. 4, that is, in step a2, when the boarding time of the passenger conforms to the boarding habit, the passenger is automatically registered with the boarding request signal according to the boarding habit, and the relevant indication button and the like can be lighted. Wherein, the content of the automatically registered elevator taking request signal comprises the traveling direction and/or the destination floor of the passenger. The specific implementation is the same as the embodiment, and will not be described repeatedly.
