Description

Technical Field

[0001] The invention relates to the technical field of elevator control, in particular to an intelligent dispatching method for a double-car elevator. Background Art

[0002] In today's rapidly developing urbanization process, the construction industry is showing a rapid development trend towards high-rise and super-high-rise buildings. As the population density in the central area of ​​the city continues to increase and land resources become increasingly scarce, high-rise and super-high-rise buildings are springing up like mushrooms after a rain, becoming an important way to solve the problem of urban space utilization.

[0003] In these high-rise buildings, elevators are a key tool for vertical transportation, and their importance is self-evident. However, traditional single-cabin elevators have exposed many insurmountable defects in the face of the growing demand for personnel transportation in high-rise buildings. Especially during peak hours in the morning and evening, when the flow of people is large and concentrated, the operating efficiency problem of single-cabin elevators is further magnified.

[0004] Specifically, traditional single-car elevators have the problem of long waiting times. During peak hours, a large number of people need to use the elevator, but the single car has a limited carrying capacity each time, which causes passengers to wait in the elevator hall for a long time, which not only affects people's travel efficiency, but also may cause crowds to gather, causing unnecessary safety hazards.

[0005] At the same time, the operation efficiency of single-car elevators is low. Since they need to stop frequently at multiple floors, and each stop takes a certain amount of time to complete the entry and exit operations of passengers, the actual effective time of the elevator running between floors is low. This inefficient operation mode is more obvious in buildings with more floors, greatly affecting the vertical traffic flow of people in the entire building.

[0006] In order to solve these problems, the technology of double-car elevator with the same shaft came into being. There are two main operating modes of the existing double-car elevator with the same shaft. The first is to make the two cars run at the same time through a rigid connection (such as patent CN219603002U), which is similar to increasing the single-time carrying capacity in principle. However, when the actual number of passengers is small, the simultaneous operation of the two cars will lead to a waste of capacity, because one of the cars may be unloaded most of the time, but it still needs to consume electricity and time to operate.

[0007] The second mode of operation is to operate in designated areas, that is, the upper car is limited to operate only in the designated high-rise area, and the lower car only operates in the designated bottom-level area, and a transfer layer is fixedly set in the middle layer (such as patent CN111422711A). This mode of operation can improve the transportation efficiency in a specific area to a certain extent, but when the number of passengers is small, there is a significant disadvantage: passengers going to high floors often need to transfer at the transfer layer, which increases their elevator ride time. Moreover, the setting of this fixed transfer layer lacks flexibility and cannot be dynamically adjusted according to the actual passenger flow and distribution. In some special cases, it may cause the waiting time of high-rise passengers to be further extended.

[0008] In summary, the existing elevator technology has certain limitations in vertical transportation of high-rise buildings. Therefore, there is an urgent need for a more intelligent, efficient and flexible dual-car elevator scheduling method that can adapt to different passenger flows and distributions. Summary of the invention

[0009] The purpose of the present invention is to provide an intelligent dispatching method for a dual-car elevator, which can accurately calculate the car running time, the stop time at each floor, the meeting time and the meeting floor of the two cars according to the real-time operation data of the cars during the elevator's upward peak period, and adaptively adjust the transfer floor, thereby significantly improving the elevator operation efficiency and reducing the waiting time of passengers.

[0010] In order to achieve the above object, the present invention is implemented through the following technical solutions: a dual-car elevator intelligent dispatching method, including an elevator intelligent dispatching system;

[0011] The dual-car elevator intelligent dispatching system consists of the following key modules:

[0012] Central control module: As the "brain" of the entire system, it is responsible for comprehensive dispatching and management. It can not only collect data from various modules in real time, but also perform complex processing and analysis on these data, including accurately calculating various time parameters related to car operation, and generating reasonable dispatching instructions based on these calculation results.

[0013] Car control module: Each car is equipped with an independent control unit, which acts like "limbs" to faithfully execute the instructions issued by the central control module and accurately feed back the real-time status of the car to the central control module, ensuring the system's precise control over the operating status of the car.

[0014] Sensor modules: Distributed on each floor and inside the elevator, they are like keen "senses" used to accurately detect key information such as the entry and exit of passengers, the position and speed of the elevator, and provide a data basis for the precise scheduling of the system.

[0015] Communication module: Like "nerves", it is responsible for ensuring smooth data transmission between modules, ensuring the real-time and accuracy of information during the transmission process, and is the key link for the collaborative work of the entire system.

[0016] User interface module: includes floor buttons, display screens in the car, and voice prompt systems. As a "window" for interacting with passengers, it can provide passengers with clear operating instructions and real-time elevator information.

[0017] Specific dispatching method for double-car upward peak period:

[0018] (1) Lower car time calculation and oncoming car analysis

[0019] The central control module first obtains the destination floor information of the current elevator below.

[0020] Starting from the lowest destination floor of the elevator below, the system calculates the arrival time at each floor based on factors such as the current speed of the car, the distance between floors, etc. Since the stop time is uncertain due to the entry and exit of passengers on each floor, the system will automatically recalculate the estimated arrival time for each of the remaining destination floors immediately after each stop.

[0021] While calculating the estimated arrival time of each floor, the system also calculates the meeting time of the lower and upper elevators, and determines the floors where the elevators may arrive. During this process, the system comprehensively considers factors such as the running direction, speed, and current position of the two elevators, and predicts the meeting situation through precise algorithms.

[0022] (2) Upper car time calculation and oncoming vehicle analysis

[0023] At the same time, the system calculates in real time the time required for the upper elevator to complete all current destination floors. Similar to the lower elevator, each time it stops at a floor, it will automatically recalculate the time required to complete the remaining destination floors.

[0024] In addition, the system will calculate the time and floor of the meeting between the upper car and the lower elevator on the return journey. This process involves comprehensive consideration of the running trajectory of the upper car and the subsequent operation of the lower car, ensuring a comprehensive analysis of the meeting situation.

[0025] (3) Transit layer determination and operation

[0026] When the meeting floor calculated by the system is in the leveling area, the floor will be automatically set as the transfer floor.

[0027] At this time, the lower elevator will automatically assign the remaining destination floors to the upper elevator, and the destination floor information will be automatically registered in the upper elevator, without any repeated operations by passengers. At the same time, the system will remind passengers in the car to prepare for transfer at the same station through voice, and the lower elevator can choose to remind passengers throughout the whole process or intermittently according to the actual situation to ensure that passengers can know the transfer information in time.

[0028] If the calculation shows that the meeting floor of the upper and lower elevators is in the non-leveling area, the floor where the lower elevator last leveled is the transfer floor. In this case, except for the different transfer floor determination method, other operations such as remaining destination floor allocation and passenger voice reminder are the same as when the meeting floor is in the leveling area.

[0029] (4) Car speed adjustment and avoidance operation

[0030] In order to ensure the safety of the car operation, the elevator above will automatically adjust its own operating speed according to the calculated meeting time, effectively avoiding possible collision accidents.

[0031] If the system calculates that the upper and lower elevators do not meet in the same operation, or the meeting floor is close to the top floor, the upper car will automatically give way to the lower car. After completing this service, the two cars will go to the first floor at the same time to prepare for the next round of service.

[0032] The present invention has the following beneficial effects:

[0033] 1. Significantly improve operational efficiency

[0034] Reduce passenger waiting time: The intelligent dispatching method of the dual-car elevator of the present invention can accurately calculate and dispatch according to real-time data. During the upward peak period, the operation tasks of the upper and lower cars are reasonably allocated through accurate calculation of the car running time, the stop time on each floor, the meeting time and the meeting floor. For example, when the system accurately determines the meeting floor and reasonably sets the transfer floor, it can quickly allocate passengers to different cars for transportation, avoiding the long waiting time caused by the unreasonable operation mode of traditional single-car elevators or existing dual-car elevators, and greatly reducing the waiting time of passengers in the elevator hall.

[0035] Optimize the car running path: During the calculation process, the uncertainty of the stop time at each floor is taken into account, and the estimated arrival time of the remaining destination floors and the meeting situation are recalculated after each stop. This enables the car to choose the optimal running path, reduce unnecessary stops and detours, and improve the overall operating efficiency. Compared with the fixed partition operation of existing double-car elevators, this method avoids the situation of empty cars or passengers transferring by detours due to unreasonable partitions, ensuring that each car can transport passengers in the most economical and efficient way in each operation.

[0036] 2. Improve passengers’ elevator experience

[0037] Intelligent voice prompts and transfer guidance: Through the voice prompt system in the user interface module, clear and timely voice prompts can be provided to passengers at key operation nodes. For example, when the system determines the transfer floor, it will accurately remind passengers in the car to prepare for transfer at the same station, and can choose full or intermittent voice reminders according to actual conditions. This intelligent voice prompt function allows passengers to clearly understand the operating steps during the elevator ride, avoiding anxiety and confusion caused by unclear transfer processes, and improving the comfort of passengers in the elevator.

[0038] Reduce the complexity of passenger operations: In the transfer layer operation, when the system determines the transfer layer, the lower elevator can automatically assign the remaining destination floors to the upper elevator and automatically complete the destination floor registration, without the need for passengers to repeat operations. This greatly simplifies the passenger operation process. Compared with traditional elevators, passengers do not need to judge the transfer floor and re-select the destination floor by themselves, making the elevator process more convenient and efficient.

[0039] 3. Enhance the safety of elevator operation

[0040] Automatic collision avoidance speed adjustment: The upper elevator can automatically adjust its operating speed according to the calculated meeting time, effectively avoiding possible collision accidents. Compared with the simple operation mode of existing double-car elevators, this speed adjustment mechanism based on precise calculation can more accurately ensure the safety of the cars during operation. Whether in normal operation or in complex meeting scenarios, it can ensure that the two cars maintain a safe distance, avoid safety accidents caused by car collisions, and ensure the safety of passengers and equipment.

[0041] 4.Flexibly adapt to different passenger flow situations

[0042] Dynamic transfer layer setting: This invention abandons the limitation of fixed transfer layers of existing double-car elevators, and can dynamically set transfer layers according to the real-time calculated meeting floor conditions. Whether meeting in a flat area or a non-flat area, the transfer layer can be reasonably determined, so that elevator scheduling can flexibly adapt to different passenger flow distributions and passenger needs. In different peak and off-peak periods and different passenger flow patterns, the elevator can be guaranteed to operate in the best way, giving full play to the capacity advantage of the double-car elevator, avoiding the problem of capacity waste or long waiting time for passengers due to changes in passenger flow.

[0043] 5. Optimize system resource utilization

[0044] Avoid waste of transport capacity: Existing double-carriage elevators are prone to waste of resources in certain operating modes, such as rigid connection and simultaneous operation when there are few passengers. The intelligent scheduling method of the present invention can reasonably arrange the operation of the cars according to actual passenger needs through accurate calculation and dynamic task allocation, avoiding empty or inefficient operation of the cars, making full and effective use of the transport capacity of the elevator system, reducing energy consumption, and improving the economy of the entire elevator system.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0053] A dual-car elevator intelligent dispatching method comprises the following steps:

[0054] Step S1, system startup: when the double-car elevator is at the upward peak period, the intelligent dispatching system is started, the system includes a central control module, a car control module, a sensor module, a communication module and a user interface module;

[0055] Step S2, data collection and initial calculation:

[0056] The central control module collects the destination floor information of the elevator below through the sensor module;

[0057] Starting from the lowest floor, the elevator below calculates the arrival time at each floor based on the current speed of the car and the distance between floors. The estimated arrival time at each floor is recalculated, and the time and floor for meeting the car above are calculated by comprehensively considering the direction, speed and current position of the car.

[0058] Step S3, upper car calculation:

[0059] Calculate the time required for the upper elevator to complete all current destination floors in real time, recalculate the time required to complete the remaining destination floors each time it stops at a floor, and calculate the time and floor for meeting the lower elevator on the return journey;

[0060] Step S4, transit layer determination and operation:

[0061] If the calculated meeting floor is in the leveling area, the floor will be set as the transfer floor. The lower elevator will automatically assign the remaining destination floors to the upper elevator and automatically register them. Passengers in the car will be prompted by voice to prepare for transfer at the same station. The lower elevator can choose to give full or intermittent voice reminders.

[0062] If the meeting floor is in the non-leveling area, the last leveling floor of the lower elevator is used as the transfer floor, and the remaining destination floor allocation and passenger reminder operations are performed in the same manner as the meeting floor in the leveling area;

[0063] Step S5, car operation adjustment:

[0064] The upper elevator automatically adjusts its running speed according to the calculated meeting time to avoid collision;

[0065] If the upper and lower elevators do not meet each other during the same operation or the meeting floor is close to the top floor, the upper car automatically gives way to the lower car. After completing this service, the two cars go to the first floor.

[0066] It should be noted that the present invention can effectively plan the operation path of the elevator, reduce unnecessary stops and detours, improve overall transportation efficiency, and reduce passenger waiting time through a series of data collection and calculation steps after the system is started, such as the central control module accurately obtaining the destination floor information of the elevator below and calculating the relevant time and meeting conditions. For example, during peak hours, the transfer floor can be quickly and accurately determined and the remaining destination floors can be allocated, so that passengers can reach the destination floor more quickly, avoiding the inefficiency caused by the disorderly operation or fixed partition operation of traditional elevators.

[0067] In the transfer layer determination and operation steps, the remaining destination layers are automatically allocated and voice prompts are given to passengers to transfer, which greatly simplifies the passenger operation process and reduces passengers' confusion and anxiety. For example, passengers do not need to manually select the destination layer again when transferring, and can get clear voice guidance, which improves the convenience and comfort of taking the elevator.

[0068] In the car operation adjustment steps, the upper elevator automatically adjusts its speed according to the meeting time, effectively preventing the occurrence of car collision accidents, ensuring the personal safety of passengers in the elevator and the normal operation of the elevator equipment. Compared with the traditional double-car elevator operation mode, it is more accurate and reliable in safety control.

[0069] The entire dispatching method performs dynamic calculations and decisions based on real-time data. Whether it is the determination of the meeting floor or the avoidance operation of the elevator car, it can be flexibly adjusted according to the actual passenger flow situation. Under different passenger flow intensities and distribution patterns, it can give full play to the capacity advantages of the double-car elevator and avoid waste of capacity or long waiting times for passengers due to fixed mode operation.

[0070] Due to the accuracy of scheduling, empty or unreasonable operation of the car is avoided, the utilization rate of the elevator system resources is improved, and energy consumption is reduced. For example, when there are fewer passengers, two cars will not operate ineffectively at the same time, which improves the economy of the elevator system.

[0071] Specifically, in the present embodiment, the central control module is used to comprehensively dispatch and manage the entire elevator system, including real-time collection and processing of data from the car control module and the sensor module; the central control module performs accurate time calculation based on the collected data, including the car running time, the stop time at each floor, the car meeting time and the meeting floor; the central control module generates reasonable dispatch instructions and sends them to the car control module through the communication module. It should be noted that the comprehensive dispatching and management functions undertaken by the central control module, including data collection, processing and instruction generation, are the core of the entire elevator intelligent dispatching. Its accurate time calculation and reasonable instruction generation can ensure the efficiency of the car operation, avoid the operation confusion and inefficiency caused by improper dispatching, and lay the foundation for the stable and efficient operation of the entire elevator system. Through the comprehensive processing of data from each module, the central control module can make the most suitable decision for the current passenger flow and car status, such as determining the transfer floor, assigning car tasks, etc., which not only improves the operation efficiency, but also ensures the good experience of passengers and the safety of elevator operation, while optimizing resource utilization, so that it can play the best performance under different working conditions.

[0072] Specifically, in this embodiment, the car control module is used to execute the instructions issued by the central control module to accurately control the operation of the car; the car control module feeds back the real-time status of the car, including the position, speed and running direction information to the central control module. It should be noted that the precise execution of the instructions of the central control module by the car control module ensures that the elevator car can operate according to the predetermined efficient operation plan. For example, the car start and stop, speed adjustment and other operations are accurately controlled to avoid operation delays or failures caused by execution deviations, ensuring the smooth progress of the entire scheduling process, thereby improving the overall operation efficiency of the elevator. The car control module feeds back the real-time status of the car to the central control module, so that the central control module can adjust the scheduling strategy in time according to the latest situation. For example, when the car speed changes or anomalies occur due to sudden situations, the central control module can respond quickly to ensure the safe operation of the elevator, and can also further optimize the subsequent scheduling arrangements and improve the adaptability to different working conditions.

[0073] Specifically, in the present embodiment, the sensor module is used to accurately detect the situation of passengers entering and exiting the car, including the number of passengers and the time of entry and exit; the sensor module monitors the position and speed of the car in real time, and provides an accurate data basis for the calculation and scheduling of the central control module. It should be noted that the sensor module accurately detects the situation of passengers entering and exiting the car and the position and speed of the car, which provides an accurate data basis for the calculation and scheduling of the central control module. Based on these data, the central control module can more accurately predict the car running time, the situation of meeting cars, etc., so as to formulate a more reasonable scheduling plan, improve the efficiency of elevator operation, and reduce the waiting time of passengers. For example, according to the number of passengers entering and exiting, the stop time of each floor can be more accurately estimated. The sensor module monitors the state of the car in real time, can promptly detect abnormal situations, such as car overspeed, abnormal stop, etc., and feedback the information to the central control module so that corresponding measures can be taken to ensure the safety of elevator operation, prevent accidents, and provide passengers with a safe and reliable elevator environment.

[0074] Specifically, in this embodiment, the communication module is used to ensure the real-time and accuracy of data transmission between the central control module, the car control module, the sensor module and the user interface module; the communication module adopts data transmission protocols and technologies to ensure smooth data interaction during the operation of the system. It should be noted that the communication module ensures the real-time and accuracy of data transmission between the modules, so that the entire elevator system can work in coordination. The instructions of the central control module can be quickly transmitted to the car control module, and the status information of the car control module and the data of the sensor module can also be fed back to the central control module in a timely manner, avoiding scheduling errors caused by data transmission delays or errors, and ensuring the efficiency and stability of elevator operation. Good communication functions promote the coordination between the modules of the system, so that the entire elevator intelligent scheduling system can respond quickly to various situations. For example, when the meeting situation changes, each module can quickly adjust the working state, optimize the operation of the car, improve the system's adaptability to complex working conditions, and further improve the overall performance of the elevator.

[0075] Specifically, in this embodiment, the user interface module is used to receive the destination floor selection information of the passenger through the floor button and transmit it to the central control module; the user interface module displays the elevator operation information in real time on the display screen in the car, including the current floor, the running direction and the destination floor; the user interface module provides passengers with clear elevator guidance through the voice prompt system, including transfer prompts and operation status prompts. It should be noted that the floor buttons, display screen and voice prompt system of the user interface module provide passengers with convenient operation methods and clear elevator information. Passengers can easily select the destination floor, and understand the elevator operation status, transfer information, etc. through the display screen and voice prompts, which reduces the difficulty and confusion of passengers' operation and improves the passengers' elevator experience. The voice prompt system provides passengers with safety prompts at key operation nodes, such as reminding passengers to pay attention to safety when the car door is about to close, informing passengers of precautions when transferring, etc., which enhances the information interaction between passengers and the elevator system, ensures the personal safety of passengers during the elevator process, and improves the safety and reliability of elevator use.

[0076] Example:

[0077] In actual application scenarios, when the double-car elevator enters the upward peak period, the intelligent dispatching system starts to operate.

[0078] The sensor module monitors the passengers entering and exiting the elevator on each floor, as well as the position and speed of the elevator in real time, and transmits this data accurately to the central control module through the communication module.

[0079] The central control module performs complex calculations based on the received data and the above scheduling method. For example, when calculating the arrival time of the elevator below at each floor, it will fully consider the possible changes in the stop time at each floor; when judging the meeting situation, it will take into account multiple factors such as the running trajectory of the elevator.

[0080] After the central control module generates accurate dispatching instructions, it sends the instructions to the car control module through the communication module. The car control module immediately executes the instructions to control the car's running speed, stop floors and other operations.

[0081] At the same time, the user interface module provides passengers with intuitive operation instructions and elevator information according to the operating status of the system. For example, when the transfer floor is determined, the passenger is prompted to transfer through voice, and the transfer-related information is displayed on the display screen to ensure that the passenger can complete the elevator process smoothly and safely.

[0082] Specifically, Figure 1 The workflow of each module of the system from passenger registration to completion of the ride is shown. The details are as follows:

[0083] The passenger first registers to take the elevator through the human-computer interaction interface, and the system enters the working state.

[0084] When passengers enter or exit the elevator, the car status (including passenger entry and exit, car load, etc.) is detected by sensors and the data is transmitted to the central control module.

[0085] The central control module completes the scheduling calculation based on the sensor data and then issues the operation instructions.

[0086] The communication module is responsible for transmitting the instructions of the central control module to the car control module to ensure that the car operates according to the instructions.

[0087] During the operation of the elevator, the information collected and feedback (including position, speed, operating status, etc.) of the upper and lower elevators are transmitted to the central control module through the communication module so that the system can monitor the operation of the elevator in real time.

[0088] Finally, the system prompts passengers to take the elevator through voice, and the LCD screen displays relevant elevator transfer information, providing passengers with a good elevator experience.

[0089] Figure 2 The specific dispatching process of a double-car elevator during the upward peak period is described in detail. The specific steps are as follows:

[0090] After the passenger registers the destination floor, the central module collects the registered destination floor information.

[0091] The system calculates the time it takes for the lower car to reach each destination floor starting from the lowest floor, and the time it takes for the upper car to reach each destination floor. During the calculation process, the estimated arrival time of the remaining destination floors will be recalculated every time the elevator stops at a floor.

[0092] At the same time, the system will also calculate the meeting time of the upper and lower elevators and the possible meeting floors.

[0093] When it is determined that the meeting floor is in the leveling area, the floor is set as the transfer floor; if it is in the non-leveling area, the last leveling floor of the lower elevator is set as the transfer floor.

[0094] After the transfer floor is determined, the lower car allocates the remaining destination floors to the upper car, and the upper car automatically registers the remaining destination floors.

[0095] The system prompts passengers to change elevators through voice, and the upper elevator adjusts its speed according to the meeting time to avoid collision.

[0096] If it is calculated that there is no chance of the upper and lower cars meeting each other or the meeting floor is close to the top floor, the upper car will give way to the lower car and after completing this service, the two cars will go to the first floor for the next round of service.

[0097] The following is an implementation example:

[0098] Suppose there is a 50-story high-rise building. During the morning rush hour, a large number of passengers are waiting on the 1st to 20th floors to take the elevator to different floors. The lower car starts to pick up passengers from the 1st floor, and some of them go to different floors such as the 10th, 15th, and 18th floors. After the central control module obtains the destination floor information of the lower car, it starts to calculate the time it takes for the lower car to arrive at each floor. During the calculation process, considering the time difference of passengers entering and exiting each floor, the estimated arrival time of the remaining destination floors is recalculated for each stop, and the meeting time and meeting floor with the upper car are calculated simultaneously.

[0099] The upper car may be performing a downward transportation task from a higher floor at this time, such as carrying passengers from the 40th floor to the 30th floor, the 25th floor, etc. The central control module also calculates the relevant time parameters of the upper car and takes into account the meeting situation with the lower car on its return journey.

[0100] Assume that after calculation, it is found that the upper and lower elevators will meet at the leveling area of ​​the 22nd floor. At this time, the system automatically sets the 22nd floor as the transfer floor. The lower elevator automatically assigns the remaining destination floors (such as the destination floors above the 18th floor) to the upper elevator, and these destination floor information are automatically registered in the upper elevator. The lower elevator prompts passengers to prepare to transfer at the 22nd floor through voice, for example: "Dear passengers, this elevator will transfer at the 22nd floor. Passengers going to the upper floors, please get ready."

[0101] The upper car adjusts its running speed according to the meeting time to ensure safe meeting. When meeting, passengers in the lower car transfer to the upper car in an orderly manner and continue to go to higher floors.

[0102] If in another case, the calculated meeting floor is in a non-leveling area, such as between the 23rd and 24th floors, the floor where the lower elevator last leveled (assuming it is the 22nd floor) is used as the transfer floor, and the lower car still assigns the remaining destination floor to the upper car and automatically registers it, and the voice prompts the passengers to transfer at the 22nd floor.

[0103] Through this implementation case, it can be seen that the dual-car elevator intelligent dispatching method of the present invention can effectively cope with the complex passenger flow during the upward peak period of high-rise buildings, improve the elevator operation efficiency, reduce the waiting time of passengers, enhance the passenger elevator experience, and ensure the safety of elevator operation. Through the collaborative work of the above modules, the dual-car elevator intelligent dispatching method of the present invention can efficiently dispatch elevators during the upward peak period of high-rise buildings, reduce the waiting time of passengers, and enhance the elevator experience.

A dual-car elevator intelligent dispatching method, characterized in that: The following steps are involved: Step S1, system startup: when the double-car elevator is at the upward peak period, the intelligent dispatching system is started, the system includes a central control module, a car control module, a sensor module, a communication module and a user interface module; Step S2, data collection and initial calculation: The central control module collects the destination floor information of the elevator below through the sensor module; Starting from the lowest floor, the elevator below calculates the arrival time at each floor based on the current speed of the car and the distance between floors. The estimated arrival time at each floor is recalculated, and the time and floor for meeting the car above are calculated by comprehensively considering the direction, speed and current position of the car. Step S3, upper car calculation: Calculate the time required for the upper elevator to complete all current destination floors in real time, recalculate the time required to complete the remaining destination floors each time it stops at a floor, and calculate the time and floor for meeting the lower elevator on the return journey; Step S4, transit layer determination and operation: If the calculated meeting floor is in the leveling area, the floor will be set as the transfer floor. The lower elevator will automatically assign the remaining destination floors to the upper elevator and automatically register them. Passengers in the car will be prompted by voice to prepare for transfer at the same station. The lower elevator can choose to give full or intermittent voice reminders. If the meeting floor is in the non-leveling area, the last leveling floor of the lower elevator is used as the transfer floor, and the remaining destination floor allocation and passenger reminder operations are performed in the same manner as the meeting floor in the leveling area; Step S5, car operation adjustment: The upper elevator automatically adjusts its running speed according to the calculated meeting time to avoid collision; If the upper and lower elevators do not meet each other during the same operation or the meeting floor is close to the top floor, the upper car automatically gives way to the lower car. After completing this service, the two cars go to the first floor.
