[0040] See also Figure 2 , an embodiment of the present invention provides an elevator call control method, which may include the following steps:

[0041] S201, receiving a call request from a user for an elevator in a building, wherein the call request is sent via a mobile terminal or a fixed terminal, and the call request includes the user's current floor position and destination floor position;

[0042] In the elevator call control system, the user's call request is the starting point of the entire control process. Its accuracy and real-time performance directly affect the response efficiency and user experience of subsequent elevators. By receiving the user's call request, the system can ensure that the user's needs can be identified in a timely and accurate manner, and then corresponding scheduling and control can be carried out.

[0043] Specifically, the user can select the current floor location and the destination floor location on a mobile terminal (such as a mobile phone application) or a fixed terminal (such as an elevator call panel) and trigger a call request. The request can contain the user's identity information and timestamp so that the system can record and manage time. The user's call request data is sent to the elevator control center via a wireless network (such as Wi-Fi, Bluetooth or mobile network). The fixed terminal transmits data with the elevator control system via a wired network. During the data transmission process, information encryption measures are taken to ensure the security and privacy protection of user information.

[0044] After receiving the call request, the receiving module of the elevator control center first parses the requested data. The parsing process includes: verifying the integrity and validity of the request (such as whether the request contains the current floor and destination floor information); extracting the user's current floor location and destination floor location, as well as the timestamp of the request.

[0045] By sending a call request through a mobile terminal or a fixed terminal, users do not need to go to the elevator entrance in person and can conveniently call the elevator at any place; the current floor location and destination floor location contained in the user request enable the system to accurately locate the user's needs and avoid reduced scheduling efficiency due to information errors; the effective call request receiving mechanism provides the necessary basic data for subsequent elevator response time calculation and scheduling optimization, which helps to realize intelligent elevator management.

[0046] S202, calculating the request response time according to the call request and the current status information of each elevator in the building;

[0047] In the elevator call control method, calculating the request response time based on the call request and the current status information of each elevator in the building is a key step in the decision-making process. By calculating the response time, the response ability and efficiency of multiple elevators to user requests can be evaluated in real time, providing data support for subsequent elevator selection.

[0048] Specifically, the user's current floor location and destination floor location can be extracted, and the timestamp of the user's request can be recorded;

[0049] After receiving the user's call request, the system first needs to extract the user's current floor and destination floor information, and record the time when the request was generated. The timestamp is the basic data for subsequent algorithm calculations, which helps to evaluate the response time, ensure that the system can accurately identify user needs, and provide the necessary time benchmark for calculating the response time. The call request can be parsed, and the user's current floor and destination floor information can be stored in the database. At the same time, the system clock is used to record the moment the request was issued, and the timestamp is associated with the user data.

[0050] Query the current status information of each elevator in the building, the current status information includes the current floor position of the elevator, the current load of the elevator, the current running direction of the elevator, and the average speed of the elevator;

[0051] This step involves obtaining real-time status information of all elevators in order to calculate the response time. The status of each elevator has a direct impact on its ability to reach the user's floor. By fully understanding the operating status of the elevators, it is ensured that the calculated response time accurately reflects the actual availability of the elevators. Real-time status information can be obtained from the elevator controller through internal monitoring sensors and communication networks, and data such as the elevator's current floor position, load, running direction and average speed are collated and stored in the operation database.

[0052] Calculate the first time the elevator is expected to take to reach the user's floor based on the elevator's current floor position, the user's current floor position and the average speed of the elevator;

[0053] Based on the user's location and the current state of the elevator, the estimated time required for the elevator to reach the user's floor without considering other influencing factors is calculated. This process is the first step in calculating the response time. The calculation of the first time provides basic data for subsequent adjustments to the elevator scheduling plan. The first time can be obtained by calculating the ratio of the floor distance between the elevator's current floor position and the user's current floor position to the average speed of the elevator.

[0054] Estimate the floor dwelling time between the current floor position of the elevator and the current floor position of the user, and calculate the second time after removing the influence of other users getting on and off the elevator based on the first time and the floor dwelling time;

[0055] This step takes into account that when an elevator is transporting users, it may need to pick up and drop off passengers on certain floors, so it is necessary to estimate the floor dwell time to more accurately assess the actual arrival time. By calculating the second time, the performance of the elevator in actual operation can be better simulated, thereby providing a more accurate response time prediction.

[0056] The dwell time between the elevator's floor and the user's floor can be estimated through historical data or statistical models based on the average dwell time of the elevator on different floors, and added to the first time to obtain the second time.

[0057] Determine a magnification factor of a second time according to the current load of the elevator, and calculate a third time considering the load of the elevator based on the second time and the magnification factor;

[0058] The load of the elevator affects its running speed, so the second time needs to be adjusted according to the load to obtain a more realistic third time. This calculation ensures that the response time takes into account the actual capacity of the elevator and improves the accuracy of the prediction.

[0059] You can set a magnification factor based on the maximum load capacity of the elevator and the current load ratio (for example, when the load is close to the maximum load, the magnification factor is 1.5), and then calculate the third time: the third time = the second time × the magnification factor.

[0060] If the current running direction of the elevator is opposite to the direction in which the user called the elevator, the fourth time required for the elevator to reach the current floor position again is estimated. Based on the third time and the fourth time, the fifth time considering the running direction of the elevator is calculated as the request response time. Otherwise, the third time is used as the request response time.

[0061] When judging that the elevator is running in the opposite direction, this step can further estimate the time it takes for the elevator to reach the user's floor, making a more accurate response time assessment, ensuring that the system can handle complex scheduling scenarios and improving the accuracy of the response time. Based on historical data statistics, the floors that the elevator needs to stay at and the time it may stay at each floor when it reaches the current floor again can be estimated, thereby obtaining the fourth time, and the fourth time plus the third time can be added to obtain the fifth time.

[0062] By calculating the request response time, the system can promptly identify the elevator that best suits the request, thereby achieving fast and efficient elevator dispatch; this process can significantly reduce the user's waiting time, make the elevator's response more timely, meet user needs, and improve user satisfaction; real-time evaluation of the elevator's response time can provide a basis for data analysis for the elevator management system, helping to improve the elevator's operating efficiency.

[0063] S203, sorting all elevators according to the request response time, and selecting elevators whose request response time is lower than a preset threshold as preliminary response elevators;

[0064] In the elevator call control method, the steps of sorting all elevators according to the request response time and screening the preliminary response elevators are aimed at quickly identifying the elevator that can best meet the user's needs by comparing the response time of different elevators. This process is the core link to achieve efficient elevator dispatching. Through reasonable sorting and screening, it ensures that users can get the expected service in the shortest time.

[0065] Specifically, after calculating the request response time of each elevator, the system can aggregate these time data into a response time list. The response time of each elevator corresponds to its unique identifier (such as the elevator number), and the data structure can be in the form of a dictionary or array. Set a preset response time threshold, which can be adjusted based on system historical data, user needs, and building characteristics. The threshold, such as "30 seconds", means that any elevator whose response time exceeds this value is inappropriate.

[0066] Use a sorting algorithm (such as quick sort or merge sort) to sort the elevators in the response time list in ascending order. This will help the system identify the elevator with the shortest request response time, so that the elevator with the shortest response time is placed at the front of the list. Traverse the sorted response time list and check whether the response time of each elevator is higher than the preset threshold. For elevators that are lower than or equal to the threshold, add them to the preliminary response elevator list. This screening process is achieved through conditional judgment. If the number of preliminary response elevators exceeds the expected number (for example, more than 3), the system can implement further optimization strategies, such as screening again according to the load status, current direction, etc. of the elevators, to ensure that the final selected elevator can efficiently serve users in terms of comprehensive capabilities. The final screened preliminary response elevators are stored in a dedicated data structure, such as a queue or a collection, for subsequent secondary screening steps. The list contains all eligible elevator identifiers and their detailed status information (such as current floor, load status, etc.).

[0067] By sorting the response times, the system can quickly identify elevators with fast response speeds, optimize elevator scheduling, improve overall service efficiency, and reduce user waiting time; by screening out elevators with request response times higher than the preset threshold, it can avoid selecting elevators that may not respond in time due to load or other reasons, thereby improving the availability of elevators; users will be more likely to get timely elevator services to meet their needs, thereby enhancing their satisfaction with elevator use.

[0068] S204, performing a secondary screening on the preliminary responding elevators to obtain a final responding target elevator.

[0069] In the elevator call control method, the step of secondary screening of the initial response elevators is intended to further accurately identify the most suitable elevator to respond to the user's call request. This process comprehensively considers multiple factors such as elevator operation stability and environmental quality on the basis of the initial screening, making the selected target elevator more reliable and real-time.

[0070] Through comprehensive consideration of multiple dimensions, we ensure that the selected elevator can not only respond to user requests in a timely manner, but also have good performance during operation to avoid service interruptions caused by elevator failures or environmental problems; the target elevator that ultimately responds can provide users with a safer and more comfortable elevator experience and improve overall user satisfaction; through multi-dimensional data analysis and screening, it reflects the intelligence of the elevator dispatching system, which can better adapt to the usage needs and environmental conditions of different buildings.

[0071] Specifically, the operation stability index of each preliminary response elevator may be calculated according to the operation data of each preliminary response elevator;

[0072] The operation stability index is an important indicator for measuring elevator performance. It comprehensively considers factors such as the elevator's failure rate and fault recovery speed to quantify the elevator's operation stability. By calculating the operation stability index, the system can identify elevators with better operation performance, ensure reliability in responding to user requests, and reduce passenger waiting time caused by elevator failures.

[0073] Specifically, the average time between failures of elevator operation, the average time to repair after an elevator failure, and the failure rate of elevator operation can be calculated from the operation data of each preliminary response elevator;

[0074] This step aims to analyze the key performance indicators of the elevator during operation, including the time between failures, the time to repair the failure, and the failure rate. These data combined can effectively reflect the operational stability of the elevator. By quantifying the failure frequency and repair efficiency of the elevator, managers and systems can identify elevators with more stable operation, and make more reliable scheduling decisions based on this information, reducing the service risks caused by failures.

[0075] The operation stability index of each preliminary response elevator is calculated according to the mean time between failures, the mean repair time, and the failure occurrence rate.

[0076] After obtaining the relevant data of the elevator's fault, this step combines these data to calculate the operation stability index. This index is a quantitative evaluation of the stability performance of the elevator in actual operation. The operation stability index provides a direct basis for the dispatch of elevators. Elevators with high stability can better ensure the safety and reliability of users when riding the elevator, so these elevators should be given priority when responding to requests.

[0077] Specifically, a calculation formula for the operation stability index can be:

[0078] Among them, the is the operation stability index, is the mean time between failures, is the mean repair time, is the total running time, is the number of elevator failures during the total operating time. is the total number of elevator operations within the total operating time. , , is the corresponding weight coefficient.

[0079] Calculate the environmental quality index of each initial response elevator according to the environmental data in each initial response elevator;

[0080] The environmental quality index evaluates the comfort and safety inside the elevator, taking into account factors such as air quality, light, noise, etc., to comprehensively evaluate the riding experience of passengers in the elevator. By evaluating the environmental quality, the system is able to select elevators that not only have good operating performance but are also environmentally friendly to increase user satisfaction and riding experience.

[0081] Specifically, a calculation formula for the environmental quality index E can be:

[0082] in, is the comfort index, is the air quality index, is the noise level index, and a, b, and c are corresponding nonlinear adjustment indexes. The comfort index can be obtained based on the weighted sum of temperature and humidity, the noise level index can be obtained based on the quantitative evaluation of noise decibels, and the air quality index can be:

[0083] in, is the concentration of gas or particles in the i-th air, and at least includes carbon dioxide and smoke concentration, k_i is the corresponding weight factor, and m is the number of monitored gases and particles.

[0084] Calculating the comprehensive performance index of each preliminary response elevator according to the operation stability index and the environmental quality index;

[0085] The comprehensive performance index is an indicator for evaluating the overall performance of an elevator. It combines the two dimensions of operational stability and environmental quality, and directly reflects the comprehensive service capabilities of the elevator. By calculating the comprehensive performance index, the system can more comprehensively understand the actual performance of the elevator, making the process of selecting the target elevator more scientific and reasonable.

[0086] The calculation formula of the comprehensive performance index can be set, such as: Comprehensive performance index = α × operation stability index + β × environmental quality index, where α and β are weight coefficients, reflecting the system's emphasis on operation stability and environmental quality. By adjusting these two coefficients, the selection of elevators can be optimized to meet different usage requirements.

[0087] Based on the comprehensive performance index, a target elevator that obtains a final response is screened.

[0088] This step conducts a final screening of the preliminary response elevators based on the comprehensive performance index to ensure that the elevator with the best performance is selected as the user's response target. This process can ensure that the selected elevator has an efficient, stable and good riding experience when actually responding to user requests, thereby improving the overall efficiency of the elevator dispatching system.

[0089] The calculated comprehensive performance indexes of all elevators can be sorted, and the elevator with the highest comprehensive performance index can be selected as the target elevator for the final response. If further optimization is required, a performance threshold can also be set to ensure that the target elevator finally selected meets the preset comprehensive performance standard.
