[0046] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] refer to Figure 1 to Figure 2 , a method for automatically opening elevator permissions, comprising:

[0048] The user registers through the mobile device APP and obtains the Bluetooth MAC address of the machine, enters personal information and authorized floors, and pushes the registration information to the cloud server for review by the property backend management system;

[0049] The property backend management system reviews the registration information submitted by the user and sets the user's permission floor. After the review is passed, the cloud server returns a specific key;

[0050] The elevator master controller obtains the user's information through the cloud server and saves the user's MAC address, specific key and authorized floor;

[0051] When the user uses the elevator for the first time, the user pairs the elevator's Bluetooth module through the mobile device APP. After the pairing is successful, the elevator Bluetooth module sends the MAC address and specific key in the pairing information to the elevator master control for verification. After the verification is passed, the pairing success status is allowed to be retained;

[0052] Every time a user's mobile device approaches the elevator, the elevator Bluetooth module actively discovers the paired mobile device and sends the Bluetooth MAC address and signal strength to the operation control module;

[0053] The operation control module obtains user authority information through the elevator master control and opens the corresponding hall call or floor authority, so that the user can normally press the hall call device to call the elevator or press the floor selector to select the authorized floor.

[0054] In this embodiment, the user only needs to complete a one-time registration through the mobile device APP to realize the automatic opening of the elevator's permissions, without carrying additional physical media. During use, the elevator can actively discover the user's mobile device and open the corresponding permissions without the user performing additional operations, which improves the convenience of use. The audit process of the cloud server and the property background management system ensures the authenticity and accuracy of the user information. The use of a specific key for identity authentication prevents unauthorized users from accessing the elevator, improving the security of the system. The data encryption and verification mechanism during the Bluetooth communication process further ensures the secure transmission of user information. The property background management system can view and manage the user's registration information and permission settings in real time, simplifying the traditional manual review and permission allocation process. The elevator master control system can automatically record and update the user's usage, providing data support for property management, and facilitating subsequent optimization and management. This method combines the advantages of mobile device APP, cloud server and elevator master control system, realizes the intelligence and automation of elevator control, and through intelligent permission management, it can reduce the ineffective operation and waiting time of the elevator, thereby reducing energy consumption and emissions.

[0055] It should be noted that the module of this solution is a dual-mode Bluetooth using classic Bluetooth and BLE Bluetooth. The MAC address of the classic Bluetooth of the mobile device is fixed, and the BLE Bluetooth address is variable. When the mobile device is used for the first time, it is connected to the module of this solution through the APP using classic Bluetooth. The module is connected to the MAC address of the mobile device. The module temporarily releases the BLE pairing mode for a period of time, and the APP then pairs with the module BLE through the BLE mode. After the pairing is successful, the module saves this BLE feature, which corresponds to the MAC address of the BT one by one.

[0056] The specific process of subsequent connection to the mobile device: The BLE module is in discoverable broadcast mode. When the mobile device approaches, it will actively connect to the paired BLE device. After the BLE module of this solution is connected to the mobile device, it will actively identify the BLE characteristics of the mobile device, the corresponding classic Bluetooth MAC address, and measure the BLE signal strength of the mobile device.

[0057] Preferably, the property backend management system reviews the registration information submitted by the user and sets the user's authorized floor. After the review is passed, the cloud server returns a specific key, which specifically includes:

[0058] The property backend management system reviews the registration information submitted by the user and sets the user's permission floor;

[0059] The cloud server generates a specific key and synchronizes the specific key and user authority information to the elevator master control. The specific key is used to verify the user's identity.

[0060] Each time a user pairs, the elevator master verifies the MAC address and specific key. After verification, pairing is allowed and the pairing information is saved.

[0061] In this embodiment, the property backend management system reviews the registration information submitted by the user. This step ensures that only qualified users are granted elevator access rights, thereby effectively preventing intrusion by illegal users. The specific key generated by the cloud server provides the user with a unique identity. This key plays a key role in identity authentication in the subsequent pairing process. Only users holding the correct key can successfully pair and access the elevator, further enhancing the security of the system. Through the property backend management system, managers can intuitively view and manage user registration information and permission settings. This centralized management method simplifies the traditional manual review and permission allocation process and improves management efficiency. At the same time, the cloud server synchronizes specific keys and user permission information to the elevator master control, so that the elevator system can obtain and update user information in real time, ensuring the accuracy and timeliness of user permissions. Users only need to complete the registration and pairing process through the mobile device APP to enjoy the automatic permission opening service of the elevator. This contactless and automated method not only improves the convenience of use, but also reduces the waiting and operation time of users. In addition, since the elevator master control can verify and save the pairing information, after the first successful pairing, users do not need to perform tedious pairing operations again, and can directly access the elevator in subsequent use, further improving the user experience. This technical solution combines the advantages of mobile device APP, cloud server and elevator master control system to realize the intelligence and automation of elevator control.

[0062] Preferably, the cloud server generates a specific key, specifically including:

[0063] The cloud server first receives the registration information pushed by the user's mobile device APP, including the user's Bluetooth MAC address, personal information and permission level;

[0064] Verify the received registration information, and after verification, store the information in the server's database;

[0065] Generate a specific key based on the user's Bluetooth MAC address, personal information, permission floor information, and the random number or timestamp inside the cloud server;

[0066] The generated key is stored in the secure storage area of ​​the cloud server and is associated with the user's registration information.

[0067] In this embodiment, after receiving the registration information pushed by the user's mobile device APP, the cloud server first verifies it to ensure the authenticity and integrity of the information. This step effectively prevents the intrusion of malicious users or illegal data and enhances the security of the system. The generated specific key is based on the user's Bluetooth MAC address, personal information, permission floor information, and random numbers or timestamps inside the cloud server. This multi-factor key generation method makes the key highly unique and random, and difficult to guess or crack, thereby further improving the security of the data; the generated key is stored in the secure storage area of ​​the cloud server and is associated with the user's registration information. This association ensures that each user has a unique key, and the key is associated with the user's The identity information is tightly bound. This design not only facilitates subsequent identity authentication and permission management, but also avoids confusion and misuse of keys. At the same time, since the key is generated based on multiple information factors of the user, even if a user's mobile device is lost or stolen, malicious users cannot access the elevator system by simply copying or forging the key, because the key is closely related to the user's identity information, and the key generated each time may be different; since the key is dynamically generated and associated with the user's registration information, the system can easily update and revoke user permissions. For example, when a user resigns or moves away, the property backend management system can simply update or delete the user's registration information, thereby automatically revoking his or her elevator usage rights without the need for additional key management operations.

[0068] It should be noted that a specific key is generated based on the user's Bluetooth MAC address, personal information, permission floor information, and the random number or timestamp inside the cloud server, including:

[0069] The user's Bluetooth MAC address, personal information, and permission floor information are preprocessed to extract key information. A custom hash function is used to hash the preprocessed key information to generate an intermediate key. The intermediate key and the preset key factor are used as input. A pseudo-random number generator inside the cloud server is used to generate a pseudo-random number as the final key. The pseudo-random number generator usually has high randomness and unpredictability and can be used to generate secure keys.

[0070] Preferably, the elevator Bluetooth module actively discovers the paired mobile device and sends the Bluetooth MAC address and signal strength to the operation control module, specifically including:

[0071] The elevator Bluetooth module determines the mobile phone signal strength through the RSSI value. When the RSSI value reaches the preset threshold, it is considered that the user's mobile phone is close to the elevator and the Bluetooth MAC address and signal strength are sent to the operation control module.

[0072] In this embodiment, the elevator Bluetooth module actively discovers paired mobile devices, and the user does not need to perform additional operations (such as pressing a button or scanning a QR code) to achieve automatic response of the elevator. This contactless and automated interaction method not only improves the convenience of use, but also reduces the waiting and operation time of the user, thereby improving the user interaction experience; using the RSSI value (received signal strength indication) to determine whether the user's mobile phone is close to the elevator is a fast and accurate method. When the RSSI value reaches the preset threshold, the system can assume that the user is ready to use the elevator and immediately send the Bluetooth MAC address and signal strength to the operation control module. This real-time response mechanism ensures that the elevator system can quickly identify and respond to the user's request, thereby improving the system's response speed and accuracy; judging the user's mobile phone signal strength by the RSSI value, the system can The corresponding function is only started when the elevator is in use, avoiding unnecessary energy waste. For example, when the user's mobile phone is away from the elevator, the system can maintain a low power consumption state to reduce energy consumption. This intelligent energy management method not only helps to save energy and protect the environment, but also extends the service life of the elevator system. The elevator Bluetooth module triggers the elevator response by identifying the paired mobile device. This identity authentication mechanism prevents unauthorized users from accessing the elevator to a certain extent. At the same time, since the system is based on Bluetooth communication, it has high anti-interference ability and stability, and can ensure stable operation in complex environments. This technical solution can support multiple paired mobile devices to approach the elevator at the same time and trigger a response, which means that during peak hours or when multiple people use the elevator together, the system can still accurately identify and respond to each user's request, avoiding response delays or errors caused by the increase in the number of users.
