Intelligent elevator dispatching method based on coupling of ETD and impatience

Abstract

This invention relates to an intelligent elevator dispatching method based on ETD (Electronic Time Demand) and anxiety coupling, belonging to the field of elevator control technology. In application, the elevator passenger first applies a specific pressing action to the call button on the call device of the floor they are calling. Then, the elevator control device activates the identity recognition device to identify the passenger. Upon successful identification, the number of dedicated elevator request triggers is checked. If there are remaining dedicated elevators, a dedicated elevator dispatch instruction is generated. Finally, the nearest available elevator to the floor is assigned. If no elevator is available, the elevator with the shortest expected waiting time is calculated and it is directed to the floor directly. After the passenger enters and presses the target floor button, the elevator goes directly to that floor without stopping. Upon arrival, the dedicated elevator mode is automatically deactivated. This invention achieves precise matching between expected arrival time and actual arrival time through behavioral triggering, identity verification, quota management, and intelligent dispatching, effectively suppressing anxiety coupling, preventing the abuse of dedicated elevators, and improving the differentiated service efficiency of the elevator system.

Description

Technical Field

[0001] This invention relates to the field of elevator control technology, and in particular to an intelligent elevator dispatching method based on ETD and anxiety coupling. Background Technology

[0002] In the field of elevator traffic flow analysis and scheduling control, there is a close relationship between passenger waiting time and Expected Time of Departure (ETD). Here, "Departure" in ETD specifically refers to the moment when the elevator arrives at the calling floor, allowing passengers to enter and depart—that is, the passenger's expected elevator arrival time (which is also the moment the passenger can depart). Research shows that passengers experience dynamic anxiety while waiting for elevators. This anxiety is not only positively correlated with absolute waiting time but is also influenced by factors such as elevator response delays and deviations from expected stops. When elevator scheduling strategies fail to meet passengers' expectations for quick, direct access, anxiety accumulates rapidly, thereby reducing passenger satisfaction with the overall elevator service. For ease of description, this interaction between passenger emotions and actual elevator performance is termed "anxiety coupling."

[0003] Most existing elevator dispatching methods employ group control algorithms, scheduling based on minimizing the average or longest waiting time. Examples include traditional collective control, dynamic partitioning scheduling, or fuzzy neural network group control methods. While these methods optimize overall operational efficiency to some extent, they still have the following shortcomings: (1) It is difficult to meet the emergency passage needs of individual users. Ordinary group control strategies treat all elevator call requests the same way and cannot provide differentiated services for users with special fast passage needs (such as VIPs, emergency personnel, and people who are unwell). Even if users press the elevator call button repeatedly, the elevator still responds according to the existing task queue order, which causes the ETD to deviate significantly from the user's psychological expectations and amplifies the anxiety coupling effect significantly.

[0004] (2) Lack of dedicated elevator mechanisms triggered by behavioral intent. Although existing technologies include modes such as "VIP elevators" or "firefighter-only elevators," these usually require pre-setting via property authorization, dedicated keys, or remote settings via mobile apps. The operation is cumbersome and cannot be quickly initiated on-site in the elevator lobby. Users cannot easily and intuitively express their intention to receive the highest priority service in a timely manner, resulting in a significant delay between emergency needs and elevator response.

[0005] (3) Lack of identity verification and usage management. Although some high-end elevators have integrated card swiping or facial recognition functions, these are mainly used to restrict elevator access and are not linked to express elevator services and usage quotas. This makes it difficult to effectively prevent users from abusing the express elevator function and to suppress malicious repeated pressing, invalid calls, and other behaviors, which may instead exacerbate the system's scheduling chaos.

[0006] Given the shortcomings of existing elevator dispatching methods, there is an urgent need to design an intelligent elevator dispatching method that can sense users' emergency passage intentions, allow users to instantly initiate dedicated elevator requests through simple and intuitive actions, and effectively prevent abuse. This method would achieve accurate matching between ETD (Emergency Time To Date) and actual arrival time without the need for additional equipment, and suppress the negative accumulation of anxiety coupling effects. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent elevator dispatching method based on ETD and anxiety coupling, in order to solve the problems existing in the current elevator dispatching method, such as the inability to perceive the user's intention to pass quickly, the lack of a dedicated elevator mechanism based on behavior triggering, and the lack of identity verification and frequency management, thereby effectively reducing the deviation between the passenger's expected arrival time and the actual arrival time, and suppressing the negative accumulation of anxiety coupling effect.

[0008] The technical solution of this invention is implemented as follows: An intelligent elevator dispatching method based on ETD and anxiety coupling is applied to an elevator system, which includes a call device, an elevator control device, and an elevator car. In use, passengers use the call device to instruct the elevator control device to move the elevator car to the called floor, and then use the elevator car's control panel to instruct the elevator control device to move the elevator car to the target floor. Specifically, the elevator system also includes an identity recognition device used in conjunction with the call device. The call device has a detection module that detects whether its own call button has been successfully pressed. The elevator control device binds the identity recognition device on the same floor to the call device. The elevator control device also contains user identity information and information on the user's remaining number of dedicated elevator requests. In use, the elevator is controlled to enter dedicated elevator mode through the following steps: S1: The passenger applies a specific pressing action to the call button on the call device of the floor where the elevator is called, triggering a dedicated elevator mode, and the call button is not currently in the call state; the specific pressing action is: within T1 seconds, T1 preferably in the range of 2 to 5, the call button is pressed more than M times, M≥2, and M is preferably 4; after the detection module of the call device detects that the call button has been successfully pressed more than M times, it sends a dedicated elevator request signal to the elevator control device; S2: After receiving the dedicated elevator request signal sent by the detection module, the elevator control device immediately controls the identity recognition device bound to the elevator call device where the detection module is located to start identifying the elevator passenger; if the identity recognition fails, the elevator control device will treat this elevator call as a normal elevator call. S3: After the identity recognition device completes the identity recognition and the recognition is successful, the elevator control device queries the remaining number of times the passenger can trigger the private elevator request. Each passenger can trigger the private elevator request N times per month, and N is preferably 2 to 4. If the remaining number of times is zero, the elevator control device will treat this call as a normal call. S4: If a passenger has remaining dedicated elevator request trigger counts, the elevator control device generates a dedicated elevator dispatch command and controls the elevator operation. Simultaneously, the elevator control device decrements the passenger's remaining dedicated elevator trigger counts for the current month by one. The specific process of the dedicated elevator dispatch command controlling elevator operation is as follows: The elevator control device selects the elevator closest to the called floor and that is currently idle, and controls it to run directly to the called floor. If there is no idle elevator, it calculates the estimated idle time of each running elevator, selects the elevator with the shortest estimated waiting time, and selects the elevator that is about to complete all its current tasks and become idle, and controls it to run directly to the called floor. After passengers enter the elevator, they press the target floor button on the car control panel, and the elevator immediately runs directly to that target floor without stopping at any other floors. S5: After the elevator reaches the target floor and the car door is fully opened, the elevator control device automatically controls the elevator to deactivate the private elevator mode and resume normal operation mode.

[0009] Furthermore, from the moment the specific pressing action ends in step S1 to the moment the identity recognition is successfully completed in step S2, the time interval shall not exceed T2 seconds, preferably 4 seconds; if the time interval exceeds T2 seconds, the elevator control device automatically determines that the identity recognition has failed.

[0010] Furthermore, in step S4, during the period from when the elevator control device generates the dedicated elevator dispatch command to when the dedicated elevator mode ends, the call button that triggers the dedicated elevator request is locked; during this locking period, any pressing operation on the call button will no longer generate any response; after the dedicated elevator mode ends, the call button will automatically unlock and resume normal call function.

[0011] Furthermore, in step S4, after the passenger enters the elevator car, the control panel can only register one target floor. If the target floor is registered incorrectly, the passenger can cancel the registration by pressing and holding the button for the incorrectly registered floor for more than 3 seconds (T3 is preferably 2), and then re-register the target floor.

[0012] Furthermore, in step S4, when there are no available elevators, the elevator with the shortest expected waiting time is calculated by the elevator control device based on the current position, running direction, current task list, and floor spacing of each task for each elevator.

[0013] Furthermore, in step S4, after the elevator arrives at the calling floor and fully opens the car door, if no passengers enter the elevator car within T4 seconds or do not operate the control panel after entering the elevator car (preferably T4 is 10), the elevator control device automatically cancels the special elevator mode, switches to normal operation mode, and rejoins the regular elevator dispatching; after switching to normal operation mode, passengers in the car can register for floors in the normal way, and the elevator responds in normal mode.

[0014] Furthermore, the elevator control device automatically resets the remaining number of private elevator requests for each passenger at midnight on the first day of each month, and the reset number is uniformly set to the preset N times.

[0015] Furthermore, the identity recognition device is a fingerprint recognition device or a facial recognition device.

[0016] Furthermore, the identity recognition device is also equipped with a speaker, which is used to remind the user in real time whether the private elevator trigger was successful, the identity recognition result, and the remaining number of private elevator trigger attempts.

[0017] Furthermore, each waiting hall on the second floor and above is equipped with an identity recognition device, and the elevator call devices on these floors are all equipped with the aforementioned detection module.

[0018] The beneficial effects of this invention are as follows: By using the specific pressing action of "pressing the call button multiple times in a short period of time," which aligns with the instinctive anxiety, the emergency passage intention of elevator passengers is transformed into a trigger signal in real time. This reduces the deviation between the expected arrival time (ETD) and the actual arrival time from several minutes to seconds, effectively suppressing the negative accumulation of the anxiety coupling effect. Combined with an identity recognition device and a monthly quota management system for dedicated elevators, this ensures that dedicated elevator services are only available to legitimate users and prevents abuse, protecting the fair use rights of ordinary users. When dispatching a dedicated elevator, priority is given to allocating an available elevator closest to the called floor. If no available elevator is available, the elevator with the shortest expected waiting time is calculated based on the elevator's location, direction of travel, task list, and floor spacing, minimizing the waiting time of the dedicated elevator while avoiding excessive interference with existing tasks. In dedicated elevator mode, the elevator does not stop at any other floors during operation, significantly shortening the single-trip time compared to ordinary group-controlled elevators. In summary, this invention systematically solves the problems of existing elevator dispatching systems, such as inability to detect emergency intentions, lack of rapid dedicated elevator mechanisms, susceptibility to abuse, and dispatching conflicts, through a closed-loop control system of "behavior triggering - identity verification - quota management - intelligent elevator dispatching - direct operation - anomaly rollback". It significantly improves the response efficiency and user satisfaction of elevator systems in differentiated service scenarios. Attached Figure Description

[0019] Figure 1 The flowchart is for an example. Detailed Implementation

[0020] like Figure 1 As shown in this embodiment, an intelligent elevator dispatching method based on ETD and anxiety coupling is applied to an elevator system. This elevator system includes a call device, an elevator control device, and two elevator cars. In use, passengers use the call device to instruct the elevator control device to move one of the elevator cars to the called floor, and then use the elevator car's control panel to instruct the elevator control device to move the elevator car to the target floor. The elevator system also includes an identity recognition device used in conjunction with the call device. This identity recognition device is a facial recognition device. Property management can directly transmit the user's facial information already collected by the intelligent door opening system to the elevator control device, eliminating the need for repeated data collection by passengers and making it more convenient. The call device contains a detection module that detects whether its call button has been successfully pressed. This detection module is generally a microswitch or a touch sensor working in conjunction with a controller. To identify rapid, continuous pressing actions; typically, the first-floor waiting area is densely populated with scattered target floors, and opening a dedicated elevator could easily lead to resource abuse and long wait times for ordinary passengers; to balance system resources and user needs, the elevator system can choose to install identification devices in waiting areas on the second floor and above, and equip the call devices on these floors with the aforementioned detection module, thereby limiting the dedicated elevator function to the second floor and above, avoiding the impact of a dedicated elevator on the overall operating efficiency; the elevator control device binds the identification devices and call devices on the same floor, and when there are multiple call devices on the same floor, each call device can also correspond to an identification device set in its vicinity; the elevator control device also contains user identity information and information on the user's remaining number of dedicated elevator requests; when in use, the elevator is controlled to enter dedicated elevator mode through the following steps: S1: The passenger applies a specific pressing action to the call button on the call device of the floor where the elevator is called, triggering the dedicated elevator mode, and the call button is not currently in a call state; the specific pressing action is: within T1 seconds, T1=3, the call button is pressed more than M times, M=4; after the detection module of the call device detects that the call button has been successfully pressed more than M times, the light on the call button is in a flashing state, while the light on the call button is in a solid state during normal elevator calls, and a dedicated elevator request signal is sent to the elevator control device; this step is performed when the call button is not currently in a call state. If the call button is currently in a pressed and active state (i.e., there is already a normal elevator call registration), the elevator control device ignores the specific pressing action and does not respond to the dedicated elevator request; S2: After receiving the dedicated elevator request signal sent by the detection module, the elevator control device immediately controls the identity recognition device bound to the elevator call device where the detection module is located to start identifying the elevator passenger; if the identity recognition fails, the elevator control device will treat this elevator call as a normal elevator call. S3: After the identity recognition device completes the identity recognition and the recognition is successful, the elevator control device queries the remaining number of times the passenger can trigger the private elevator request. Each passenger can trigger the private elevator request N times per month, where N=3. If the remaining number of times is zero, the elevator control device will treat this call as a regular call. S4: If a passenger has remaining dedicated elevator request trigger counts, the elevator control device generates a dedicated elevator dispatch command and controls the elevator operation. Simultaneously, the elevator control device decrements the passenger's remaining dedicated elevator request counts for the month by one. At midnight on the first day of each month, the elevator control device automatically resets the remaining dedicated elevator request counts for each passenger, setting the reset count to a preset N. The specific process for controlling elevator operation with the dedicated elevator dispatch command is as follows: The elevator control device selects the elevator closest to the called floor and that is currently idle, and controls it to run directly to the called floor. If there is no idle elevator, it calculates the estimated idle time of each running elevator, selects the elevator with the shortest estimated waiting time, and selects the elevator that is about to complete all its current tasks and become idle, and controls it to run directly to the called floor. After passengers enter the elevator, they press the target floor button on the car control panel, and the elevator immediately runs directly to that target floor without stopping at any other floors. S5: After the elevator reaches the target floor and the car door is fully opened, the elevator control device automatically controls the elevator to deactivate the private elevator mode and resume normal operation mode.

[0021] To shorten the response time for entering dedicated elevator mode, improve elevator dispatch efficiency, and reduce user anxiety, such as... Figure 1 As shown, from the moment the specific pressing action ends in step S1 to the moment the identity recognition is successfully completed in step S2, the time interval shall not exceed T2 seconds, where T2=4; if the time interval exceeds T2 seconds, the elevator control device will automatically determine that the identity recognition has failed.

[0022] To make this intelligent elevator dispatching method more reasonable, in step S4, from the time the elevator control device generates the dedicated elevator dispatching command until the dedicated elevator mode ends, the call button that triggered the dedicated elevator request is locked; during this locking period, any pressing operation on the call button will no longer generate any response; after the dedicated elevator mode ends, the call button will automatically unlock and resume normal call function. The end of the dedicated elevator mode includes the following two situations: one is that the dedicated elevator is completed normally, that is, after the elevator reaches the target floor and the car door is fully opened, the elevator control device automatically deactivates the dedicated elevator mode; the other is that the dedicated elevator is canceled. Regardless of how the dedicated elevator ends, after the dedicated elevator mode ends, the call button will automatically unlock and resume normal call function. When multiple dedicated elevator requests from different floors exist simultaneously and elevator resources are insufficient, the elevator control device responds sequentially according to the order of the request time. Subsequent dedicated elevator requests enter the waiting queue and are dispatched immediately after the current dedicated elevator is completed, while maintaining the direct access characteristic of the dedicated elevator mode; if there are multiple idle elevators, multiple dedicated elevator requests from different floors can be responded to simultaneously, and each dedicated elevator operates independently.

[0023] like Figure 1 As shown, in step S4, after a passenger enters the elevator car, the control panel only allows registration of one target floor. If the target floor is registered incorrectly, the passenger can cancel the registration by pressing and holding the button for the incorrectly registered floor for more than T3 seconds (T3=2), and then re-register the target floor. By limiting each dedicated elevator to registering only one target floor, the abuse of the dedicated elevator mode by passengers using multiple floors can be effectively prevented, guiding them to cherish each dedicated elevator trigger opportunity, thereby ensuring the singleness and directness of the dedicated elevator operation path and improving overall scheduling efficiency.

[0024] like Figure 1As shown, in step S4, when there are no available elevators, the elevator with the shortest expected waiting time is calculated by the elevator control device based on the current position, direction of travel, current task list, and floor spacing of each task. The estimated time for a running elevator to reach the calling floor is calculated as follows: the time required to complete the current task list + the time from the current floor after completing the current task list to the calling floor. The time required to complete the current task list refers to the total time required for the elevator to sequentially complete all its registered internal and external calls (i.e., all floors in the task list) from its current position and direction of travel. This time includes the travel time for each segment (calculated based on floor spacing and average elevator speed), as well as the door opening and closing time for each stop and the average passenger entry and exit time. The floor after completing the current task list refers to the floor the elevator finally stops at after sequentially completing the last stop in the task list. The time to reach the calling floor refers to the time required for the elevator to travel directly from the final stop floor after completing all tasks to the calling floor (calculated based on floor spacing and average speed, without intermediate stops). The elevator control system calculates the estimated waiting time for each operating elevator and selects the elevator with the lowest calculated value as the designated elevator for response. If multiple elevators have the same estimated waiting time, the elevator closest to the calling floor or traveling in the same direction is given priority.

[0025] like Figure 1 As shown, in step S4, after the elevator arrives at the called floor and the car door fully opens, if no passenger enters the elevator car within T4 seconds or does not operate the control panel after entering the elevator car, T4=10. The control panel gives a voice prompt urging the passenger to enter, and the elevator control device automatically cancels this special elevator mode. The remaining special elevator trigger count consumed by this special elevator request is not restored, and the system switches to normal operation mode and rejoins regular elevator dispatch. After switching to normal operation mode, passengers in the car can register for floors in the normal way, and the elevator responds in normal mode. In use, after the elevator car door is fully closed and the elevator starts running, cancellation or modification of the target floor is no longer accepted; cancellation and re-entry are only allowed before the elevator door is closed. This design avoids the following situation: passengers successfully trigger the special elevator through a specific pressing action and identity verification, but after the elevator arrives, they delay entering the car for some reason (such as temporarily leaving, answering a phone call, forgetting their intention, etc.), causing the elevator to stay at the called floor for a long time and unable to respond to other passengers' normal elevator calls, thus wasting system resources. By setting up an automatic rollback mechanism with a timeout of T4 seconds, the timeliness of the dedicated elevator service is ensured, while maintaining the overall operational efficiency of the elevator system.

[0026] To make this intelligent elevator dispatching method more convenient to use, the identity recognition device is also equipped with a speaker, which is used to remind the user in real time whether the elevator dispatch was successful, the identity recognition result, and the remaining number of elevator dispatches.
