In these high-rise buildings, elevators, as an indispensable vertical transportation tool, undertake the important mission of fast and safe movement of personnel and materials, and play a pivotal role in people's daily life and work. However, there are still some problems: 1. Traditional elevator control methods mainly rely on complex wired connections and fixed control system architecture. In order to achieve communication between the elevator car and each floor and precise control of the elevator operation, a large number of cables need to be laid inside the building, which not only makes the installation process extremely cumbersome, consumes a lot of manpower, material resources and time, but also increases the initial construction cost of the system; Second, due to the long-term use of cables and the influence of environmental factors, they are prone to aging and damage, which leads to unstable or even interrupted signal transmission, thus affecting the normal operation of the elevator. The maintenance and replacement of these cables is a difficult task that requires professional personnel to operate, which is not only time-consuming and labor-intensive, but also incurs high maintenance costs; 3. The fixed architecture of traditional control systems lacks flexibility and is difficult to adapt to changes in building usage functions or adjustments in user needs. Once the operation mode or control logic of the elevator needs to be modified, large-scale transformation and updating of hardware equipment is often required, which undoubtedly increases the difficulty and cost of system upgrades and improvements; To this end, an elevator control method, device, electronic device and storage medium based on Bluetooth networking are proposed.

[0023] Figure 1 is a flowchart of an elevator control method based on Bluetooth networking according to an embodiment of the present invention. It should be noted that if there are substantially the same results, the method of the present application is not based on Figure 1 The process sequence shown is limited. Figure 1 As shown: An elevator control method based on Bluetooth networking, comprising the following steps: Step 1: Obtain the Bluetooth modules in the elevator car, the elevator call panels on each floor, and the elevator control system, and build a Bluetooth network. Specifically, install high-performance, low-power Bluetooth 5.0 modules in the elevator car, the elevator call panels on each floor, and the elevator control system; initialize these Bluetooth modules, including device name, communication frequency band, encryption method, etc.; establish a Bluetooth network to ensure that the Bluetooth modules in the elevator car, the elevator call panels on each floor, and the elevator control system can discover and connect to each other; Step 2: Based on the intelligent load balancing mechanism, the communication load of each Bluetooth module is monitored in real time, and the data transmission path is dynamically adjusted according to the communication load of each Bluetooth module. Specifically, the load balancing monitoring module monitors the communication load of each Bluetooth module every [X] minutes (for example, 5 minutes); collects the load indicators such as the data transmission volume, number of connections, and processing delay of each Bluetooth module in the past [Y] hours (for example, 2 hours) as the historical load situation; and obtains the hardware specifications, processing capacity and other parameters of each Bluetooth module at the same time; Step 3: Obtain the user's elevator riding information, analyze and predict the user's elevator riding habits based on machine learning algorithms. Specifically, collect the user's elevator riding history data, including the elevator riding time, departure floor, destination floor, riding frequency, etc.; use machine learning algorithms such as decision trees, random forests or neural networks to analyze and model these data; predict the user's possible elevator riding needs in the future, such as the floors they may visit in a specific time period; Step 4: Based on the Bluetooth function of the user's mobile terminal, pair and connect with the Bluetooth module in the elevator call panel on the floor. Specifically, when the user is ready to take the elevator on the floor, turn on the Bluetooth function of the mobile terminal (such as a mobile phone); the mobile terminal automatically searches for nearby Bluetooth devices, finds the Bluetooth module in the elevator call panel on the floor, and initiates a pairing connection request for pairing connection; Step 5: Input the user's destination floor information into the mobile terminal and send it to the Bluetooth module in the elevator call panel. Specifically, after identity authentication is passed, the user enters the destination floor information on the application interface of the mobile terminal; the system performs a validity check on the input destination floor information. If the input floor does not exist or does not comply with the elevator operation rules (for example, a negative floor is entered or exceeds the highest floor of the building), an error prompt is issued to the mobile terminal, requiring the user to re-enter the information; Step 6: Based on the Bluetooth networking, the Bluetooth module transmits the received destination floor information to the elevator control system. Specifically, after the Bluetooth module in the elevator call panel receives the destination floor information input by the user, it uses the AES-256 encryption algorithm to encrypt the information, and transmits the encrypted destination floor information to the elevator control system through the Bluetooth networking; Step 7. According to the received destination floor information, the elevator control system dispatches the elevator car to the user's floor. Specifically, after receiving the encrypted destination floor information, the elevator control system decrypts and processes it; in combination with the current operating status of the elevator (such as the current floor, operating direction, registered destination floor, etc.) and the destination floor information of other users, an optimization scheduling algorithm is used for scheduling. For example, if there are multiple elevators to choose from, elevators that are closer to the user's floor and have a smaller load are prioritized to minimize the number of elevator stops. For example, users going to similar floors are assigned to the same elevator to shorten the average waiting time of users. By reasonably arranging the operating order and speed of the elevators, the operating efficiency of the elevators is improved; the selected elevator car is dispatched to the user's floor and stops when it reaches the destination floor.

[0024] In one embodiment, specifically, in step 2, the intelligent load balancing mechanism uses a weighted polling algorithm, and the weight of each Bluetooth module is dynamically adjusted according to its historical load and processing capacity. The weight calculation formula is: ; in, For the The weight of the Bluetooth module, For the The historical load of each Bluetooth module, For the The processing power of a Bluetooth module, and is the weight coefficient, and ; Assume that there are three Bluetooth modules A, B, and C, whose historical loads are L1, L2, and L3 respectively, and whose processing capacities are C1, C2, and C3 respectively. The weight coefficients are and are 0.6 and 0.4 respectively; then the weight WA of Bluetooth module A is calculated as follows: WA=0.6×L1+0.4×C1; Based on the weight of each Bluetooth module, a weighted polling algorithm is used to dynamically adjust the data transmission path. For example, when new data needs to be transmitted, a Bluetooth module with a higher weight is preferentially selected for transmission.

[0025] In one embodiment, specifically, in step 4, the pairing and connection process between the mobile terminal and the Bluetooth module in the elevator call panel includes multiple identity authentications, the identity authentication includes biometric identification and password verification, the biometric identification includes fingerprint, facial feature and iris feature identification; the calculation formula for the identity authentication pass probability P is: P = (F × Wf + Pw × Wp) / (Wf + Wp); Where F is the biometric matching degree, Wf is the biometric weight, Pw is the password matching degree, and Wp is the password weight; if P is greater than or equal to the preset threshold Th, the identity authentication is passed; After the Bluetooth module in the elevator call panel receives the pairing request, it automatically starts the multi-factor authentication process; First, biometric identification is performed. Users can choose to use fingerprints, facial features, or iris features for verification. Assuming fingerprint identification is used, the system will collect the user's fingerprint information and match it with the pre-stored fingerprint template to obtain the fingerprint matching degree F; then the user enters the password, and the system will compare the entered password with the preset password to obtain the password matching degree Pw; Assume that the biometric weight Wf is 0.7, the password weight Wp is 0.3, and the preset threshold Th is 0.8. The probability P of identity authentication passing is calculated as follows: P=(F×0.7+Pw×0.3) / (0.7+0.3); If P is greater than or equal to 0.8, the identity authentication is passed and the Bluetooth connection is established; otherwise, the connection is rejected and a prompt is issued to the user; In one embodiment, specifically, if the identity authentication fails, the connection establishment is rejected, and a prompt is issued to the user, and the number of authentication failures Nf is recorded; if Nf exceeds a set threshold Nmax, the connection function is temporarily locked, and the locking time Tlock is calculated as follows: Tlock = Nf × ΔT; Among them, ΔT is the lock time increment corresponding to the unit number of failures; Set the lock time increment ΔT corresponding to the number of unit failures to 5 minutes; Set the threshold Nmax of verification failure times to 5 times; 1. The first identity verification failed: User A is about to take the elevator and uses a mobile terminal to pair with the Bluetooth module of the elevator call panel and perform identity authentication; Because the password entered by user A is incorrect, the identity verification fails; The system refuses to establish a connection, sends a message to user A's mobile terminal saying "Authentication failed, please re-authenticate", and records the authentication failure. At this time, the number of authentication failures Nf is 1; 2. Second identity verification failed: User A re-enters the information for identity verification, but the fingerprint match does not meet the requirement and the verification fails again; The system rejects the connection again, issues a prompt, and updates the number of verification failures Nf to 2; 3. The third identity verification failed: User A still fails to pass the authentication because both the biometric and password verification do not match; The system continues to reject the connection, issues a prompt, and Nf is updated to 3 times; 4. The fourth identity verification failed: User A was in a hurry to take the elevator and was flustered when entering information, resulting in the fourth verification failure; The system rejects the connection as usual, issues a prompt, and Nf increases to 4 times; 5. The fifth identity verification failed: User A still fails to pass the identity authentication successfully; The system rejects the connection, issues a prompt, and temporarily locks the connection function because Nf (5 times) exceeds the set threshold Nmax (5 times); The lock time Tlock is calculated as: Tlock = 5 × 5 = 25 minutes. In the next 25 minutes, user A cannot establish a connection with the Bluetooth module of the elevator call panel through his mobile terminal; After the 25-minute lockout period, User A can retry authentication to establish a connection.

[0026] In one embodiment, specifically, in step five, if the destination floor information entered by the user is invalid, an error prompt is sent to the mobile terminal, requiring the user to re-enter the information; when the user enters the floor information, the validity of the input is verified in real time. For example, if the elevator only serves floors 1 to 10, then when the user enters "11", the application should immediately display an error prompt; when the user clicks the Submit button, the application will perform more stringent verification, which includes checking whether the input is a number, whether it is within the range of floors served by the elevator, whether it contains illegal characters, etc.

[0027] In one embodiment, specifically, in step six, the communication between the Bluetooth module in the elevator call panel and the elevator control system adopts encrypted transmission, and the encryption algorithm is the AES-256 algorithm; the AES (Advanced Encryption Standard) algorithm, especially the AES-256 version, is selected as the algorithm for encrypted communication. AES-256 is known for its high security, high efficiency and wide application, and can provide strong encryption protection to prevent data from being eavesdropped or tampered with during transmission.

[0028] In one embodiment, specifically, in step seven, the elevator control system optimizes the scheduling when scheduling the elevator car operation, combining the current operating status of the elevator and the destination floor information of other users. The optimized scheduling includes reducing the number of elevator stops and shortening the average waiting time of users. In order to improve the operating efficiency of the elevator, the control system will try to reduce the number of elevator stops by optimizing scheduling, which usually involves merging destination requests for multiple similar floors so that the elevator can serve more users in one operation. The control system will also consider the waiting time of users, and predict and evaluate the impact of different scheduling schemes on user waiting time through intelligent algorithms. When selecting a scheduling scheme, it will give priority to schemes that can shorten the average waiting time of users. According to actual needs, the control system can set different priorities for different types of requests. For example, emergency requests or requests from users with special needs (such as people with limited mobility) may be given higher priority.
