Description

Technical Field

[0001] This invention relates to the field of elevator access control technology, and in particular to a method and system for automatically opening elevator access control. Background Technology

[0002] With the continuous advancement of modern building technology and the increasing demand for intelligent systems, elevators, as an important component of building transportation, have become a focus of attention for their safety and convenience. Traditional elevator control methods often rely on physical buttons or IC cards, which not only limits user flexibility but also increases management and maintenance costs.

[0003] To address these challenges, various technical solutions for automatic access control in elevators have emerged in recent years. These solutions are typically based on advanced wireless communication technologies such as Bluetooth and Wi-Fi, enabling contactless interaction between users and elevators. However, these solutions still have some shortcomings in practical applications, such as cumbersome pairing processes, low security, and poor user experience. Summary of the Invention

[0004] In view of this, the present invention proposes a method and system for automatically opening elevator permissions, which can effectively solve the defects of existing technologies such as cumbersome pairing process, low security and poor user experience.

[0005] The technical solution of this invention is implemented as follows:

[0006] A method for automatically granting access permissions to an elevator includes:

[0007] Users register via mobile app and obtain their device's Bluetooth MAC address, while also entering personal information and authorized floors. The registration information is then pushed to the cloud server for review by the property management system.

[0008] The property management system reviews the registration information submitted by the user, sets the user's access floors, and returns a specific key to the cloud server after the review is approved.

[0009] The elevator control system obtains user information through a cloud server and saves the user's MAC address, specific key, and authorized floors.

[0010] When a user uses the elevator for the first time, they pair the elevator's Bluetooth module with a mobile app. After successful pairing, the elevator's Bluetooth module sends the MAC address and a specific key from the pairing information to the elevator's main control unit for verification. Once the verification is successful, the pairing success status is retained.

[0011] Each time a user's mobile device approaches the elevator, the elevator's Bluetooth module actively discovers the paired mobile device and sends its Bluetooth MAC address and signal strength to the control module.

[0012] The operation and control module obtains user permission information through the elevator master control and grants corresponding external call or floor permissions, enabling users to normally call the elevator by pressing the external call button or select the floor they are authorized to by pressing the floor selector.

[0013] As a further optional solution to the method of automatically granting access to the elevator, the property management system reviews the registration information submitted by the user, sets the user's authorized floors, and after approval, the cloud server returns a specific key, specifically including:

[0014] The property management system back-end reviews the registration information submitted by users and sets the floors that users are allowed to access;

[0015] The cloud server generates a specific key and synchronizes the specific key and user permission information to the elevator main control system. The specific key is used to verify the user's identity.

[0016] Each time a user pairs up, the elevator master controller verifies the MAC address and a specific key. Once the verification is successful, pairing is allowed and the pairing information is saved.

[0017] As a further optional solution to the method of automatically granting access to the elevator, the cloud server generates a specific key, specifically including:

[0018] The cloud server first receives registration information pushed from the user's mobile device APP, including the user's Bluetooth MAC address, personal information, and authorized floor;

[0019] The received registration information is verified, and once the verification is successful, the information is stored in the server's database.

[0020] A specific key is generated based on the user's Bluetooth MAC address, personal information, access level information, and random numbers or timestamps within the cloud server.

[0021] The generated key is stored in a secure storage area on the cloud server and is associated with the user's registration information.

[0022] As a further optional solution to the method of automatically granting access to the elevator, the elevator Bluetooth module actively discovers paired mobile devices and sends the Bluetooth MAC address and signal strength to the control module, specifically including:

[0023] The elevator Bluetooth module determines the mobile phone signal strength by using the RSSI value. When the RSSI value reaches a preset threshold, it assumes that the user's mobile phone is close to the elevator and sends the Bluetooth MAC address and signal strength to the control module.

[0024] An automatic access control system for elevators includes:

[0025] The user registration module is used for user registration and obtaining the local device's Bluetooth MAC address, while also entering personal information and permission levels, and pushing the registration information to the cloud server;

[0026] The property management back-end module is used to review the registration information submitted by users, set the user's authorized floors, and send it to the cloud server after the review is approved. The cloud server generates and returns a specific key to the mobile APP and the elevator main control system.

[0027] The elevator main control module is used to receive and save the user's MAC address, specific key, and authorized floor information;

[0028] The Bluetooth pairing module is used to pair with the user's mobile device APP via Bluetooth. After successful pairing, the MAC address and specific key in the pairing information are sent to the elevator main control module for verification, and the pairing success status is retained after successful verification.

[0029] The mobile device discovery module is used to actively discover paired mobile devices and obtain their Bluetooth MAC addresses and signal strength each time a user's mobile device approaches the elevator.

[0030] The operation and control module is used to obtain user permission information through the elevator main control module based on the received Bluetooth MAC address, and accordingly grant the corresponding external call or floor permissions, so that the user can normally call the elevator by pressing the external call button or select the floor with permission by pressing the floor selector.

[0031] As a further optional solution to the aforementioned automatic elevator access control system, the property management back-end module includes:

[0032] The review unit is used by the property management system to review the registration information submitted by users and set the user's access floors.

[0033] A specific key generation unit is used to generate a specific key on the cloud server and synchronize the specific key and user permission information to the elevator main control. The specific key is used to verify the user's identity.

[0034] The verification unit is used to verify the MAC address and a specific key each time a user is paired. Once the verification is successful, pairing is allowed and the pairing information is saved.

[0035] As a further optional solution to the aforementioned automatic elevator access control system, the specific key generation unit includes:

[0036] The receiving subunit is used by the cloud server to first receive registration information pushed from the user's mobile device APP, including the user's Bluetooth MAC address, personal information and permission level;

[0037] The verification subunit is used to verify the received registration information. After successful verification, the information is stored in the server's database.

[0038] The execution subunit is used to generate a specific key based on the user's Bluetooth MAC address, personal information, access level information, and random numbers or timestamps inside the cloud server.

[0039] The storage sub-unit is used to store the generated key in a secure storage area of ​​the cloud server and is associated with the user's registration information.

[0040] A computing device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described method for automatically granting access to elevators.

[0041] A computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the above-described method for automatically granting access to elevators.

[0042] The beneficial effects of this invention are as follows: Users only need to complete a one-time registration through a mobile device APP to automatically grant elevator access without the need for additional physical media. During use, the elevator can proactively detect the user's mobile device and grant the corresponding permissions without requiring additional user operation, thus improving ease of use. The review process through the cloud server and property management system ensures the authenticity and accuracy of user information. Authentication using a specific key prevents unauthorized users from accessing the elevator, improving system security. Data encryption and verification mechanisms during Bluetooth communication further guarantee the secure transmission of user information. The property management system can view and manage user registration information and permission settings in real time, simplifying the traditional manual review and permission allocation process. The elevator control system can automatically record and update user 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 control system to achieve intelligent and automated elevator control. Through intelligent permission management, it can reduce ineffective elevator operation and waiting time, thereby reducing energy consumption and emissions. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0044] Figure 1 This is a flowchart illustrating a method for automatically granting access permissions to an elevator according to the present invention.

[0045] Figure 2 This is a schematic diagram of the components of an elevator automatic access control system according to the present invention. Detailed Implementation

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] refer to Figures 1 to 2 A method for automatically granting access permissions to elevators, comprising:

[0048] Users register via mobile app and obtain their device's Bluetooth MAC address, while also entering personal information and authorized floors. The registration information is then pushed to the cloud server for review by the property management system.

[0049] The property management system reviews the registration information submitted by the user, sets the user's access floors, and returns a specific key to the cloud server after the review is approved.

[0050] The elevator control system obtains user information through a cloud server and saves the user's MAC address, specific key, and authorized floors.

[0051] When a user uses the elevator for the first time, they pair the elevator's Bluetooth module with a mobile app. After successful pairing, the elevator's Bluetooth module sends the MAC address and a specific key from the pairing information to the elevator's main control unit for verification. Once the verification is successful, the pairing success status is retained.

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

[0053] The operation and control module obtains user permission information through the elevator master control and grants corresponding external call or floor permissions, enabling users to normally call the elevator by pressing the external call button or select the floor they are authorized to by pressing the floor selector.

[0054] In this embodiment, users only need to complete a one-time registration via a mobile device app to automatically grant elevator access, eliminating the need for additional physical media. During use, the elevator proactively detects the user's mobile device and grants the corresponding permissions without requiring any additional user intervention, thus improving ease of use. The verification process through the cloud server and property management system ensures the authenticity and accuracy of user information. Authentication using a specific key prevents unauthorized user access to the elevator, enhancing system security. Data encryption and verification mechanisms during Bluetooth communication further guarantee the secure transmission of user information. The property management system can view and manage user registration information and permission settings in real time, simplifying the traditional manual review and permission allocation process. The elevator control system automatically records and updates user usage, providing data support for property management and facilitating subsequent optimization and management. This method combines the advantages of mobile device apps, cloud servers, and the elevator control system to achieve intelligent and automated elevator control. Through intelligent permission management, it reduces unnecessary elevator operation and waiting time, thereby lowering energy consumption and emissions.

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

[0056] The specific process of connecting to the mobile device: The BLE module is in a discoverable broadcast mode. When the mobile device approaches, it will actively connect to the paired BLE device. After the BLE module 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 management system reviews the registration information submitted by the user, sets the user's access floors, and after approval, the cloud server returns a specific key, specifically including:

[0058] The property management system back-end reviews the registration information submitted by users and sets the floors that users are allowed to access;

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

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

[0061] In this embodiment, the property management system reviews the registration information submitted by users. This step ensures that only qualified users can be granted elevator access, thereby effectively preventing unauthorized users from intruding. The specific key generated by the cloud server provides users with a unique identity. This key plays a crucial role in authentication during the subsequent pairing process. Only users with the correct key can successfully pair and access the elevator, further enhancing system security. Through the property management system, administrators can intuitively view and manage user registration information and permission settings. This centralized management approach simplifies the traditional manual review and permission allocation process, improving management efficiency. Simultaneously, the cloud server synchronizes specific keys and user permission information to the elevator control system, enabling the elevator system to 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 a mobile app to enjoy automatic access to the elevator. This contactless and automated method not only improves ease of use but also reduces user waiting and operation time. Furthermore, since the elevator control system can verify and save pairing information, users do not need to perform cumbersome pairing operations again after the first successful pairing and can directly access the elevator in subsequent uses, further enhancing the user experience. This technical solution combines the advantages of mobile app, cloud server, and elevator control system to achieve intelligent and automated elevator control.

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

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

[0064] The received registration information is verified, and once the verification is successful, the information is stored in the server's database.

[0065] A specific key is generated based on the user's Bluetooth MAC address, personal information, access level information, and random numbers or timestamps within the cloud server.

[0066] The generated key is stored in a secure storage area on 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 intrusion by malicious users or illegal data, enhancing system security. The generated specific key is based on multiple factors, including the user's Bluetooth MAC address, personal information, access level information, and random numbers or timestamps generated internally by the cloud server. This multi-factor key generation method makes the key highly unique and random, difficult to guess or crack, thereby further improving data security. The generated key is stored in the secure storage area of ​​the cloud server and associated with the user's registration information. This association ensures that each user has a unique key, and the key is linked to the user's registration information. The tight binding of identity information not only facilitates subsequent identity verification and access management but also avoids key confusion and misuse. Furthermore, since the key is generated based on multiple user information factors, 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, as the key is closely related to the user's identity information and may be different each time it is generated. Because 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 leaves their job or moves out, the property management system can simply update or delete the user's registration information, automatically revoking their elevator access without requiring 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, access level information, and a random number or timestamp within the cloud server. Specifically, this includes:

[0069] The system preprocesses the user's Bluetooth MAC address, personal information, and access level information, extracts key information, and uses a custom hash function to hash the preprocessed key information to generate an intermediate key. The intermediate key and a preset key factor are used as input to generate a pseudo-random number as the final key through a pseudo-random number generator inside the cloud server. 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 paired mobile devices and sends the Bluetooth MAC address and signal strength to the control module, specifically including:

[0071] The elevator Bluetooth module determines the mobile phone signal strength by using the RSSI value. When the RSSI value reaches a preset threshold, it assumes that the user's mobile phone is close to the elevator and sends the Bluetooth MAC address and signal strength to the control module.

[0072] In this embodiment, the elevator's Bluetooth module actively discovers paired mobile devices, eliminating the need for users to perform additional operations (such as pressing buttons or scanning QR codes) to achieve automatic elevator response. This contactless and automated interaction method not only improves ease of use but also reduces user waiting and operation time, thereby enhancing the user experience. Using RSSI (Received Signal Strength Indicator) values ​​to determine if a user's phone is near the elevator is a fast and accurate method. When the RSSI value reaches a preset threshold, the system considers the user ready to use the elevator and immediately sends the Bluetooth MAC address and signal strength to the control module. This real-time response mechanism ensures the elevator system can quickly identify and respond to user requests, improving system response speed and accuracy. By determining the user's phone signal strength through RSSI values, the system can respond when the user truly needs it. The system activates relevant functions only when the elevator is in use, avoiding unnecessary energy waste. For example, when a user's phone is away from the elevator, the system can maintain a low-power state to reduce energy consumption. This intelligent energy management not only helps save energy and protect the environment but also extends the lifespan of the elevator system. The elevator's Bluetooth module triggers an elevator response by identifying paired mobile devices. This authentication mechanism prevents unauthorized users from accessing the elevator to some extent. At the same time, because the system is based on Bluetooth communication, it has high anti-interference capabilities and stability, ensuring stable operation in complex environments. This technical solution can support multiple paired mobile devices to approach the elevator simultaneously and trigger a response. This means that during peak hours or when multiple people are using the elevator together, the system can still accurately identify and respond to each user's request, avoiding response delays or errors caused by an increase in the number of users.

[0073] An automatic access control system for elevators includes:

[0074] The user registration module is used for user registration and obtaining the local device's Bluetooth MAC address, while also entering personal information and permission levels, and pushing the registration information to the cloud server;

[0075] The property management back-end module is used to review the registration information submitted by users, set the user's authorized floors, and send it to the cloud server after the review is approved. The cloud server generates and returns a specific key to the mobile APP and the elevator main control system.

[0076] The elevator main control module is used to receive and save the user's MAC address, specific key, and authorized floor information;

[0077] The Bluetooth pairing module is used to pair with the user's mobile device APP via Bluetooth.

[0083] The verification unit is used to verify the MAC address and a specific key each time a user is paired. Once the verification is successful, pairing is allowed and the pairing information is saved.

[0087] The execution subunit is used to generate a specific key based on the user's Bluetooth MAC address, personal information, access level information, and random numbers or timestamps inside the cloud server.

[0088] The storage sub-unit is used to store the generated key in a secure storage area of ​​the cloud server and is associated with the user's registration information.
