Description

Technical Field

[0001] The invention relates to the technical field of elevator control, in particular to a method and equipment for elevator passenger traffic planning. Background Art

[0002] In modern urban life, high-rise buildings are increasing day by day. As key equipment for vertical transportation, the operation efficiency and passenger experience of elevators are crucial.

[0003] In the daily operation of commercial buildings and residential buildings, there are significant problems with the use of elevators during peak hours. For example, during the morning rush hour in commercial buildings, a large number of grassroots staff call for elevators, and passengers from all floors rush into the elevators in an unorderly manner, causing the passengers to interfere with each other when the elevators arrive at the stops on each floor, resulting in serious congestion and blockage. This situation greatly affects the operating efficiency of the elevator, causing the elevator to start and stop frequently, and stay on each floor for too long, which in turn greatly increases the waiting time for subsequent passengers waiting for the elevator.

[0004] Similarly, during the evening rush hour in residential areas, residents returning home from get off work call for the elevator in large numbers on the ground floor, and after rushing into the elevator, similar chaotic and crowded conditions occur when it stops at each floor.

[0005] The existing elevator control systems lack effective planning and management mechanisms for passenger flow in their designs. Most of them only focus on basic lifting and lowering operation control, and are unable to reasonably divert and guide passengers during peak hours, making it difficult to meet the needs of efficient and orderly elevator riding experience in actual use scenarios, which in turn leads to long-term problems such as poor elevator experience and low operating efficiency during peak hours. Summary of the invention

[0006] The purpose of the present invention is to provide a method and device for elevator passenger traffic planning, aiming to solve the problems of passenger congestion and low operating efficiency in elevators during peak hours. Through innovative methods and devices, orderly elevator riding is achieved, elevator operating efficiency is improved, and passenger elevator riding experience is enhanced.

[0007] The present invention is achieved through the following technical solutions:

[0008] ①Indication system

[0009] Design an intelligent indication system that can obtain passengers' destination floor information in real time, and combine the high, medium and low floor distribution and the current number of people in each area to make accurate station planning and dynamic prompts. By rationally arranging display devices in the car, it provides clear and intuitive station guidance for passengers, ensuring that passengers can stand and enter and exit the elevator in an orderly manner according to the plan, forming an efficient and orderly elevator traffic order.

[0010] ②Communication linkage

[0011] Establish a close communication link between the indication system, controller, group control system and destination floor selector system. The destination floor selector is deeply integrated with third-party floor registration equipment such as card reader, QR code recognition, video recognition, etc. to form an intelligent elevator traffic control system. In this system, all parties exchange data through high-speed and stable communication protocols to achieve real-time sharing and collaborative processing of passenger elevator call information, destination floor information and elevator operation status information, providing solid data support for subsequent accurate elevator dispatch and passenger management.

[0012] ③Real-time interactivity

[0013] The indication system is endowed with a high degree of real-time interactive capability. By building an advanced communication unit into the system, it is able to instantly obtain the real-time number of passengers and floor distribution information in each elevator after the group control system dispatches the elevator. Based on these dynamic data, the indication system can quickly adjust the station guidance strategy to ensure that passengers can get accurate and timely station guidance in different elevator riding scenarios, effectively avoiding passenger confusion and congestion caused by information lag.

[0014] ④ Elevator control computing and processing equipment

[0015] Core hardware architecture

[0016] The integrated display module and voice playback module are connected to the system via CAN bus or network lines, enabling remote flexible settings and precise control of indication functions.

[0017] The host controller processor is the core brain of the device, integrating large-capacity memory, high-speed USB interface, multi-type network interface and stable CAN communication module. These components work together to efficiently perform data communication, collection and storage operations.

[0018] The device has powerful data processing capabilities. Through the internal driver and advanced encoding and decoding modules, it can quickly convert the collected data into parallel or serial data streams and transmit them through specific buses (such as I 2 C, GPIO and I 2 S, etc.) output precise control signals to achieve accurate display of the display module and smooth voice prompt function of the voice playback module.

[0019] Expanded connectivity with external devices

[0020] The controller is designed with a flexible serializer module that can convert internal data into serial signals for seamless connection and stable communication with the elevator controller. At the same time, an interface for extended display is reserved to facilitate system function expansion according to actual application scenarios.

[0021] The peripheral module interface is highly compatible and can easily connect to various external devices such as gate machines, face detection equipment, IC card readers, person detection modules, etc., further enriching the system's data collection channels and control methods.

[0022] ⑤Dynamic station planning and display

[0023] With the help of group control floor selectors and elevator control systems, real-time monitoring and accurate collection of passenger flow information is carried out during peak hours. Through in-depth analysis of these data, intelligent and reasonable elevator dispatching operations are realized, and the real-time number of passengers in each elevator and the distribution of passengers' destination floors are accurately estimated.

[0024] The above key information is transmitted to the station planning instruction processor through a high-speed communication unit. Based on advanced algorithms, the station planning instruction processor quickly processes and precisely calculates the received data to generate detailed indication area planning and station display instructions.

[0025] These instructions are sent to the voice reminder module, the car station display module or the projection module. During the operation of the elevator, every time it arrives at a stop, the system can automatically sense and instantly update relevant parameters, such as the number of passengers in the current car and the change of the destination floor, and then quickly adjust the station planning and display content to achieve a truly dynamic station display.

[0026] The voice reminder unit has a variety of audio receiving methods. It can receive pre-customized audio files through the USB interface or the network, and accurately play the prompt voice according to the system instructions, clearly guiding passengers to enter and exit the elevator car in an orderly manner, avoiding congestion and chaos caused by poor communication.

[0027] ⑥ Space division inside the car

[0028] Based on the scientific average standing space standard, the space in the car is carefully divided into multiple standing grids. Each grid is an independent display prompt unit. By installing a high-precision display device on the floor of the car or using advanced projection display technology, the display content of the grid is adjusted in real time and dynamically according to the instructions issued by the elevator control computing and processing equipment. This grid-based space management method can flexibly guide passengers to stand reasonably in the car according to the actual number of passengers and the distribution of destination floors, maximize the use of the car space, and ensure the smooth entry and exit of passengers.

[0029] ⑦Backend administrator processing module

[0030] Build a powerful back-end administrator processing module to provide managers with an intuitive and convenient operation interface. Administrators can flexibly modify and set various system parameters and operating rules based on the information statistics database.

[0031] For example, administrators can accurately set the start and end times of peak hours according to the peak hour characteristics of different building types (commercial buildings or residential buildings); they can also customize display rules under different conditions for different elevator riding scenarios and needs, such as giving priority to passengers on specific floors to pass quickly during extreme peak hours. This highly flexible management method greatly improves the system's adaptability to diverse application scenarios and operating efficiency.

[0032] ⑧Outdoor display module

[0033] The hall display module is designed to match the car module, using the same core technology and algorithm logic to achieve accurate guidance for passengers who call the elevator. The hall display module can guide passengers who call the elevator to queue up in order according to the destination floor according to the current operating status of the elevator and the distribution of passengers in the car, ensuring that when the elevator arrives, passengers can enter the car quickly and orderly, further optimizing the orderliness and efficiency of the entire elevator process.

[0034] In summary, the present invention has the following beneficial effects:

[0035] Improved operating efficiency: Through precise elevator dispatching strategies and passenger station planning, the number of elevator stops and the length of time the elevator spends on each floor during peak hours are significantly reduced, thereby greatly improving the overall operating efficiency of the elevator and effectively shortening the average waiting time for passengers.

[0036] Optimized elevator riding experience: Reasonable standing guidance and dynamic display functions allow passengers to clearly understand their standing positions and entry and exit order during the elevator riding process, avoiding crowding and chaos, creating a comfortable and orderly elevator riding environment, and greatly improving the passengers' elevator riding experience.

[0037] Enhanced system flexibility: Administrators can flexibly adjust system settings according to actual conditions, so that the system can perfectly adapt to application scenarios of different building types, different peak hours and different elevator needs, ensuring that the system can perform at its best in various complex environments.

[0038] Optimal resource allocation: With the help of intelligent elevator traffic control systems, refined management and optimal allocation of elevator resources can be achieved, the transportation capacity of each elevator can be fully utilized, and the operating efficiency and service quality of the entire building's vertical transportation system can be improved.

[0045] Figure 6 The present invention is a schematic diagram of the structure of an elevator passenger traffic planning device. DETAILED DESCRIPTION

[0046] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application are clearly and completely described. Obviously, the embodiments described below are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] Reference Figures 1 to 6 , an elevator passenger traffic planning device, wherein: the traffic planning device includes a display module, a voice playback module, a host controller processor, a serializer module, an extended display interface, and a peripheral module interface;

[0048] The display module is connected via a CAN bus or a network line, and can remotely receive control instructions and display text, graphic and icon information;

[0049] The voice playback module is connected to the system audio output interface and can play voice prompts in multiple languages ​​and tones, with adjustable volume;

[0050] The host controller processor integrates a large-capacity memory, a high-speed USB interface, a stable and efficient network interface, and a CAN communication module, and can analyze and process received data, convert the data into parallel or serial data streams through the internal driver and encoding and decoding module, and output control signals according to a specific bus protocol;

[0051] The serializer module is used to convert the parallel data inside the device into a serial signal that complies with the elevator controller interface standard for communication;

[0052] The extended display interface is used to connect an additional display device;

[0053] The peripheral module interface is used to connect to external devices.

[0054] The external device includes one or more of a gate machine, a face detection device, an IC card reader and a person detection module.

[0055] The traffic planning equipment works in coordination with the group control system and the destination floor selector system, collects passenger flow data during peak hours through the group control selector and elevator control, including the time, location, destination floor, number and distribution of passengers in the elevator car, and transmits the data to the equipment; based on the collected passenger flow data, a preset intelligent algorithm is used to achieve reasonable elevator dispatching decisions, optimize the operation and scheduling of the elevator, and accurately estimate the real-time number of passengers and the changes in the distribution of the destination floors of each elevator during operation; and transmits the estimated key information to the station planning instruction processor in real time through the communication unit.

[0056] The station planning instruction processor generates instructions for area planning and station display based on the information received on the real-time number of elevator passengers and the distribution of destination floors using a built-in algorithm. The area planning and station display instructions are sent to the voice reminder module and the in-car station display module or projection module respectively through the signal transmission channel.

[0057] The voice reminder unit can receive pre-customized audio files through a USB interface or a network to implement intelligent voice synthesis, and can generate and play prompt voices according to system instructions; its voice playback is set with priority playback, and is used to give priority to playing important prompt voices at key elevator nodes.

[0058] Based on the average standing space standard for people, the space in the car is divided into several standing grids. Each standing grid serves as an independent display prompt unit and is equipped with an independent display control module for receiving and executing instructions from the elevator control computing and processing equipment. Through the car floor display device or the projection display device, the display content of each standing grid is adjusted according to the instructions of the elevator control computing and processing equipment, including the occupancy status of the grid, the passenger's destination floor information and the standing guide icon.

[0059] The division and display of the grids can be adaptively adjusted according to the actual number and distribution of passengers in the car. When there are fewer passengers, some grids can be merged, and when there are more passengers, the grid division can be refined.

[0060] It also includes a background administrator processing module, which is connected to the host controller processor through a network to provide an administrator with a visual operation interface. The administrator can access the information statistics database through this interface. The database stores the historical operation data of the elevator, passenger flow data, elevator demand data at different time periods, and various operating parameters and configuration information of the system; the administrator can modify and set various parameters and operating rules of the system according to the actual use of the building, the characteristics of peak hours, and the needs of special events.

[0061] The backend administrator processing module has a permission management function, which can ensure that only authorized administrators can perform system setting operations.

[0062] An elevator passenger traffic planning method comprises the following steps:

[0063] Step S1, designing an indication system, which can obtain the destination floor information of passengers by integrating with various control systems of the elevator, and combine the high, medium and low area distribution of the building floors and the number and distribution of people in each area at present, and use algorithms to generate real-time dynamic prompts and station planning schemes;

[0064] Step S2: The standing position planning scheme is presented to passengers through the display device and voice prompt system in the elevator car, guiding passengers to stand and enter and exit the elevator in an orderly manner according to the plan.

[0065] Step S3: construct a communication linkage mechanism among the indication system, the controller, the group control system and the destination layer selector system, so that all parties can share data and instructions;

[0066] Step S4, the destination floor selector and one of the third-party floor registration devices among the card reader, QR code recognition, and video recognition form an intelligent elevator traffic control system, and the parties exchange data through a communication protocol;

[0067] Step S5: The indication system has real-time interactive capability, and can obtain dynamic information such as the real-time number of passengers, floor distribution, and operation status of the elevator after group control dispatch, and adjust the position guidance strategy and display content accordingly;

[0068] Step S6: A display module is set outside the elevator hall, which uses the same core technology and algorithm logic as the module inside the car. Through real-time communication with the elevator control system, it obtains information on the current operating status of the elevator, the distribution of passengers in the car, and the elevator call status of each floor, and provides guidance for passengers who call the elevator to queue up according to the destination floor.

[0069] The present invention has the following beneficial effects:

[0070] Improved operating efficiency: Through precise elevator dispatching strategies and passenger station planning, the number of elevator stops and the length of time the elevator spends on each floor during peak hours are significantly reduced, thereby greatly improving the overall operating efficiency of the elevator and effectively shortening the average waiting time for passengers.

[0071] Optimized elevator riding experience: Reasonable standing guidance and dynamic display functions allow passengers to clearly understand their standing positions and entry and exit order during the elevator riding process, avoiding crowding and chaos, creating a comfortable and orderly elevator riding environment, and greatly improving the passengers' elevator riding experience.

[0072] Enhanced system flexibility: Administrators can flexibly adjust system settings according to actual conditions, so that the system can perfectly adapt to application scenarios of different building types, different peak hours and different elevator needs, ensuring that the system can perform at its best in various complex environments.

[0073] Optimal resource allocation: With the help of intelligent elevator traffic control systems, refined management and optimal allocation of elevator resources can be achieved, the transportation capacity of each elevator can be fully utilized, and the operating efficiency and service quality of the entire building's vertical transportation system can be improved.

[0074] Practical application scenarios of the present invention:

[0075] 1. Data Collection Phase

[0076] External device data collection

[0077] Outside the elevator hall, there are a variety of third-party floor registration devices, including but not limited to card readers, QR code scanners and video recognition devices. The card reader can quickly read the IC card information held by the passenger to obtain his / her identity and authority data; the QR code scanner can accurately identify the elevator QR code on the passenger's mobile phone or other device, which contains relevant information such as the passenger's destination floor; the video recognition device uses advanced image recognition technology to perform facial recognition on the passenger and then associate his / her elevator record.

[0078] These external devices transmit the collected passenger call information and destination floor information to the group control system and destination floor selector system in real time through high-speed and stable communication lines. During the transmission process, an encrypted data transmission protocol is used to ensure the security and integrity of the data and prevent data leakage or tampering.

[0079] Elevator internal data feedback

[0080] High-precision sensors are installed inside the elevator, which can monitor the number of passengers in the car, passenger distribution and the operating status of the elevator (such as the current floor, running direction, etc.) in real time.

[0081] These internal monitoring data will also be fed back to the group control system in a timely manner, providing key basis for the group control system to conduct comprehensive data analysis and elevator dispatching decisions.

[0082] (II) Elevator dispatch and information processing stage

[0083] Intelligent elevator dispatching by group control system

[0084] After receiving all the data from the third-party floor registration equipment outside the hall and the internal sensors of the elevator, the group control system immediately starts the intelligent elevator dispatching algorithm. The algorithm comprehensively considers many factors such as the current position of the elevator, the running direction, the number of passengers in the car, the demand for elevator calls from passengers on each floor, and the distribution of destination floors.

[0085] Through weighted analysis and real-time calculation of these factors, the group control system determines the most optimized elevator dispatching plan, selects the elevator that best responds to the elevator call request, and sends the elevator dispatching command to the corresponding elevator controller. For example, during the morning rush hour in a commercial building, if there are many elevator calls for high-rise buildings and an elevator is currently traveling up without a load, the group control system will give priority to allocating high-rise elevator calls to that elevator.

[0086] Data transfer and integration

[0087] At the same time, the group control system transmits the elevator dispatch information, the number of passengers in each elevator, and the floor distribution to the station planning instruction processor through a dedicated communication unit in a high-frequency and low-latency manner. During the transmission process, a data verification mechanism is used to ensure the accuracy of data transmission. If a data transmission error is found, a retransmission operation will be performed immediately.

[0088] (III) Position planning and command output stage

[0089] Station planning instruction generation

[0090] After receiving the data from the group control system, the station planning instruction processor uses the built-in advanced algorithm for fine processing. The algorithm will calculate the best station planning plan based on the spatial layout of the car, the current passenger distribution, and the destination floor of the passengers who are about to enter the car.

[0091] For example, for a car that is about to have multiple passengers enter, the processor will rationally plan the standing positions in different areas of the car (such as the front area near the car door and the back area inside the car) according to the order of the passengers' destination floors, ensuring that passengers on higher floors are in the back row and passengers on lower floors are in the front row, making it convenient for subsequent passengers to enter and exit.

[0092] Command output and distribution

[0093] The station planning instruction processor generates detailed indication area planning and station display instructions based on the calculation results. These instructions are sent to the voice reminder module, the in-car station display module and the projection module respectively. During the instruction sending process, a priority queuing mechanism is adopted to ensure that important instructions (such as the exit reminder instructions for passengers who are about to arrive at the floor) can be delivered to the corresponding modules in priority and accurately.

[0094] (IV) Dynamic adjustment stage in the car

[0095] Preparation before arriving at the floor

[0096] When the elevator approaches each stop, the system accurately senses the elevator's operating status through the position sensor and speed sensor in the car. When it is a certain distance away from the target floor (such as 2-3 seconds in advance), the system automatically triggers the station adjustment mechanism.

[0097] Parameter update and display adjustment

[0098] The system updates the relevant parameters in the car in real time, including changes in the current number of passengers (such as passengers temporarily changing their destination floor in the car) and adjustments to the distribution of destination floors.

[0099] Based on the new parameters, the station planning instruction processor quickly recalculates the station planning and sends the updated station display instructions to the in-car station display module and projection module. These modules will immediately update the display content, such as changing the color or display pattern of the station grid to clearly prompt passengers to adjust their stations.

[0100] At the same time, the voice reminder module will play corresponding prompt voices according to the new station planning, such as "Passengers going to the 5th floor please move to the right side of the car", guiding passengers to adjust their positions in an orderly manner and ensure that when the elevator door opens, passengers can enter and exit the car quickly and smoothly.

[0101] (V) Off-site guidance stage

[0102] Data synchronization outside the hall

[0103] The off-hall display module obtains the current elevator operating status, passenger distribution in the car, and information about the floor to be reached through real-time communication with the group control system and the system in the car.

[0104] Elevator passenger guidance

[0105] Based on the acquired data, the hall display module uses the same station planning algorithm as the car module to calculate the optimal queue order for the passengers who call the elevator. For example, for a hall with three elevators, when one of the elevators is about to arrive and there are many passengers going to the upper floors in the car, the hall display module will prompt the passengers who call the elevator to go to the upper floors to queue in front of the elevator, and the passengers who go to the lower floors to queue in front of other elevators.

[0106] By combining intuitive graphics (such as arrow indicators, highlighted floor numbers, etc.) and voice prompts (such as "Passengers going to floors above the 10th floor, please queue up at the elevator on the left") on the display screen outside the hall, passengers who call the elevator are guided to queue up in an orderly manner according to their destination floor to wait for the elevator, avoiding passengers from blindly gathering outside the hall and scrambling for the elevator.

[0107] (VI) Administrator Setup Phase

[0108] Parameter setting interface

[0109] Administrators access the information statistics database through the user-friendly operation interface of the back-end administrator processing module. The interface provides clear menu options and operation instructions to facilitate administrators to perform various setting operations.

[0110] Flexible rule setting

[0111] Administrators can set the specific time range of peak hours based on the usage characteristics of the building and the rules of peak hours. For example, for commercial buildings, the morning peak hours can be set from 8:30 to 9:30 a.m. on weekdays, and the evening peak hours can be set from 5:30 to 6:30 p.m.; for residential buildings, the evening peak hours can be set from 7:00 to 8:00 p.m. on weekdays.

[0112] In addition, administrators can also customize display rules under different conditions for different peak hours and special situations. For example, on important event days in commercial buildings, rules can be set to prioritize the fast passage of passengers on the event floors; during the peak period of moving in residential buildings, rules can be set to provide special standing instructions for passengers carrying large items. Through these flexible settings, the system can better adapt to various complex usage scenarios, ensuring the efficiency of elevator operation and the comfort of passengers.

[0113] Case 1: Implementation scenario during morning rush hour in a commercial office building

[0114] In a 30-story commercial office building, during the morning rush hour on weekdays (8:00-9:30), people flow densely and are concentrated on the lower floors to enter the elevators and go to the office areas on the higher floors.

[0115] Outside the elevator hall, employees scan the QR code generated by the mobile phone APP to call the elevator, and the card reader identifies the employee's access card to obtain the information of the office floor where he is located. The video recognition device also monitors the on-site personnel to ensure the comprehensiveness of the data. The data is quickly transmitted to the group control system and the destination floor selector system.

[0116] Based on the received information, the group control system comprehensively considers the current position, running direction and passenger load of each elevator, and allocates passengers going to high floors to the elevators that are going down and have fewer passengers in the car, and allocates passengers going to the middle and low floors to the elevators that are about to arrive and have enough space. For example, when an elevator is on the 15th floor and is going down, with only 5 passengers in the car, and at this time there are multiple passengers going to the 20th floor or above calling for the elevator, the group control system will allocate the elevator calls of these high-rise passengers to this elevator.

[0117] Inside the elevator, the sensor monitors in real time that there are 5 passengers in the car going to the 8th, 12th and 18th floors respectively. When a new passenger enters the car, the system automatically updates the passenger information and transmits this data to the station planning instruction processor. The station planning instruction processor calculates the station planning based on the new passenger destination floor distribution. For example, for the upcoming stop on the 10th floor, it will mark the area near the door as the exit area for passengers going to the 8th floor through the station display module in the car, and display the corresponding station instructions on the floor of the car through the projection module. At the same time, the voice reminder module plays the prompt tone "Passengers going to the 8th floor please prepare to exit at the door."

[0118] When the elevator stops at each floor, the system quickly updates the passenger information and station planning in the car to ensure that passengers can enter and exit the elevator efficiently and orderly. The display module outside the hall also guides the passengers who call the elevator to queue up in front of different elevators according to the destination floor according to the operation of the elevator, avoiding confusion and disorderly crowding.

[0119] Through this implementation method, the operating efficiency of elevators has been significantly improved during the morning rush hour in commercial office buildings. The average operating time of each elevator has been shortened by about 15%, the waiting time of passengers has also been greatly reduced, and the overall elevator experience has been greatly improved.

[0120] Case 2: Implementation scenario for high-rise residential buildings during evening peak hours

[0121] In a 40-story residential building, 6:00-8:00 p.m. is the evening rush hour for residents to go home.

[0122] Residents call the elevator in the elevator hall on the first floor by swiping a card or using facial recognition. The equipment outside the elevator hall transmits the residents' floor information to the group control system. The group control system allocates elevators reasonably according to the operating conditions of each elevator and the distribution of passengers in the car. For example, if there are three elevators, one has just descended from the high floor with a full load, one is empty on the middle floor, and the other is on the bottom floor with some passengers in the car going to the middle and high floors, the group control system will give priority to allocating new elevator call requests to the empty elevator on the middle floor to balance the load of each elevator.

[0123] Inside the elevator, when the car reaches a certain floor, the system quickly adjusts the station planning based on the passenger information collected by the destination floor selector. For example, if there are passengers going to the 10th, 20th and 30th floors in the car, when a new passenger enters and goes to the 25th floor, the station planning instruction processor will instruct the new passenger to stand near the middle of the car through the display module and projection module, and remind the new passenger through voice, "Passengers going to the 25th floor, please stand in the middle of the car."

[0124] At the same time, the display module outside the hall will remind residents who call for the elevator to queue up in front of the appropriate elevator according to the operation progress of the elevator and the distribution of passengers in the car. For example, when an elevator is about to arrive and there are many passengers going to the upper floors in the car, the display outside the hall will remind residents going to the upper floors to queue up in front of the elevator, and residents going to the middle and lower floors to wait in front of other elevators, avoiding elevator congestion and chaos caused by residents blindly following.

[0125] After a period of operation, the operating efficiency of the elevator in this high-rise residential building during the evening peak period has increased by about 20%, residents' satisfaction with the use of the elevator has been significantly improved, and complaints and congestion have been significantly reduced.

[0126] Through these two implementation cases, it can be seen that the elevator passenger traffic planning method and the device thereof of the present invention can effectively solve the elevator congestion problem during peak hours in different scenarios, improve operating efficiency and passenger experience, and have strong practicality and adaptability.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
