Technical Field

[0001] The present invention belongs to the field of intelligent device management, and in particular is a cabinet intelligent lock security management system based on physical ID association. Background Art

[0002] The door locks used in the traditional power cabinet management model are traditional locks composed of a mechanical lock body and a metal key. They are prone to rust and wear, which increases the maintenance cost of the locks. There is no record of the opening and closing process, and the person responsible cannot be traced when problems occur. When staff go out for inspection, they need to carry a large number of keys. When they arrive at the site, they may not be able to complete their work because they bring the wrong key, which affects work efficiency. Due to the difficulty of supervision, the access control of most power cabinets has been damaged or the cabinet door locks have been open for a long time, which hides potential safety hazards of electricity.

[0003] Power cabinets contain a large amount of critical power operation data and sensitive data such as user power usage information. In the existing intelligent management of power cabinets, there are insufficient security measures, which affect the transmission, storage and processing of data. In serious cases, they may even be attacked by cyber attacks and cause data leakage, which will not only affect the normal operation of the power system, but also may cause serious damage to user privacy and corporate commercial interests. Summary of the invention

[0005] To achieve the above-mentioned purpose, the first aspect of the present invention provides a cabinet smart lock security management system based on physical ID association, including: a smart lock device end, a mini-program end and an intelligent management and control platform. Among them, the smart lock device end is used to execute the switch operation of the lock and feedback status information; the mini-program end communicates and controls the smart lock device and provides an operation interface for the user; the intelligent management and control platform performs intelligent management and monitoring of cabinet equipment assets.

[0006] Preferably, the smart lock device includes:

[0009] (3) Motor drive module: After the lock device receives the operation command from the applet, it controls the motor to rotate forward or reverse through the main controller to realize the opening and closing lock operation;

[0010] (4) Storage module: stores device ID, Bluetooth name and MAC address;

[0011] (5) Step-down power supply module: used to step down the working voltage from the 12V interface DC power supply to 3.3V;

[0017] Preferably, the device ID sets the cabinet code and the smart lock code to the same identifier as the device ID. The device ID can be written into the storage chip of the lock device by program burning or mini-program writing. After the mini-program establishes a Bluetooth connection with the lock device, the lock device can read the device ID from the storage chip and send it to the mini-program end in the form of a data packet.

[0018] Preferably, the Bluetooth communication module is used for communication between the mini program and the lock device, including: using the AES-256 symmetric encryption algorithm to encrypt and decrypt data packets exchanged during the communication process, using the HTTPS protocol for network communication between the mini program and the server, and using the SHA-256 algorithm for one-way encryption of the data storage process.

[0019] Preferably, the mini program end includes: a message module for viewing messages pushed by the system; an operation module for users to search and operate smart lock devices; a work module, including five functional sub-modules: permission approval, operation records, smart devices, application for permissions and authorization management; a contact module: used to manage department information and users under the department; including: creating or joining a department, viewing or modifying department information; my module: including device registration, device permission, password change, logout and avatar upload sub-functions.

[0021] The mini program in the present invention is developed based on the application development framework, components and API provided by the WeChat official account. The WeChat mini program has strong cross-platform compatibility and can run on mobile terminals with Android, IOS and Windows operating systems. Developers do not need to develop and maintain applications on multiple platforms, which greatly reduces the cost and difficulty of application development.

[0025] The server in the present invention adopts a development model with front-end and back-end separation. The development of the front-end and back-end is relatively independent. If the requirements change, as long as the interface and data format remain unchanged, the front-end and back-end can be maintained and optimized and upgraded separately. The system architecture design with front-end and back-end separation is to facilitate developers to write codes, while improving the flexibility and scalability of the system. After the front-end and back-end projects are completed, the dependencies in the configuration file can be called to realize the integrated operation of the front-end and back-end projects.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

In order to reduce the difficulty of the work of power inspectors, a unique interactive design is made for the Bluetooth communication process between the mini-program and the smart lock on the power cabinet. At the same time, there are dual prompts of voice and text during the operation.

[0029] (3) In view of the security risks existing in the system, a system security system is constructed using cryptography and access control models. The AES symmetric cryptographic algorithm in cryptography is used to encrypt the Bluetooth communication process, the SHA one-way cryptographic algorithm is used to encrypt database storage, and the HTTPS in the asymmetric cryptographic system is used to encrypt the network communication layer between the applet and the server, thus ensuring the asset security of the power cabinet and the security of related data information.

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0035] See also Figure 1-Figure 3 The first aspect of the present invention provides a cabinet smart lock security management system based on physical ID association, including:

[0036] The three subsystems are the smart lock device, the mini program and the smart management and control platform. The smart lock device is used to execute the lock switch operation and feedback the status information; the mini program communicates and controls the smart lock device and provides an operation interface for the user; the smart management and control platform performs intelligent management and monitoring of cabinet equipment assets.

[0037] Smart lock devices include:

[0038] (1) Main controller module: As the central processor of the smart lock, it is used to schedule various functional modules and coordinate the overall operation;

[0039] (2) Bluetooth communication module: used for communication between the applet and the lock device, transmitting information between the two. The applet can issue instructions to read the lock device information and control the lock device to open or close. Fu Ruikun's Soc-FR8016HA low-power Bluetooth chip is selected as the main control chip of the smart lock device. FR8016HA integrates the main controller and Bluetooth communication module required for IoT products and provides a stable Bluetooth connection. Including: using the AES-256 symmetric encryption algorithm to encrypt and decrypt the data packets exchanged during the communication process, using the HTTPS protocol for network communication between the applet and the server, and using the SHA-256 algorithm for one-way encryption of the data storage process.

[0040] The server-side program is deployed in the cloud server of Tianyi Cloud. The cloud server needs to be registered after purchase. The cloud server will open port 443 only after the registration application is approved. The following steps can complete the configuration of HTTPS communication between the mini program and the server.

[0041] Step 1: Purchase a domain name on Alibaba Cloud's official website and register it;

[0042] Step 2: After filing, bind the domain name with the website's IP address and port number;

[0043] Step 3: Apply for a digital SSL certificate and bind the SSL certificate with your domain name and other identity information for server authentication and data transmission encryption;

[0044] Step 4: After the certificate is issued, a digital certificate file containing the public key will be generated. The CA certificate and private key are configured in the reverse proxy server Nginx in the server.

[0045] The SHA-256 algorithm is mainly used to encrypt sensitive data in the database. For example, when encrypting sensitive data user passwords, the account and password entered by the user when registering a new account are converted into a byte array and transmitted to the server via HTTPS communication. After receiving the transmitted password, the server uses the byteArrayToHexString function in the SHA256Util class to convert the byte array into a hexadecimal string, and then adds the random salt generated in the SaltUtil class to the password string in the PasswordUtil class, and uses the encrypt function to encrypt it one-way to generate the ciphertext of the current password, which is stored in the password and salt fields of the sys_user table together with the random salt. The user enters the account password on the login interface of the applet. After receiving the data, the server uses the SHA-256 algorithm to recalculate the salted hash value of the password with the received password and the value of the salt field in the database. If it is consistent with the password field, the login can be successful.

[0046] (3) Motor drive module: After the lock device receives the operation command from the applet, it controls the motor to rotate forward or reverse through the main controller to realize the switch lock operation; the durable GM14-030 motor is selected to realize the switch action of the cabinet smart lock.

The circuit integrates an H-bridge drive circuit designed with MOS tubes. It has fewer external devices, lower cost, and higher reliability of the whole machine. The power supply voltage range of the chip is 2.2V-6.5V. It has four drive functions: forward, reverse, brake and standby, which can meet the different working requirements of smart lock devices. The control logic is rich and can almost meet all requirements of motor speed control.

The device ID can be written into the storage chip of the lock device by program burning or applet writing. After the applet establishes a Bluetooth connection with the lock device, the lock device can read the device ID from the storage chip and send it to the applet end in the form of a data packet. The AT24C01A storage chip is selected as the hardware storage module. The chip provides a 1024-bit serial electrically erasable programmable read-only memory EEPROM. Data is not lost after power failure and can be used to store data in low-power devices.

[0048] (5) Step-down power module: used to step down the operating voltage from the 12V interface DC power supply to 3.3V; the power chip used in the step-down power module is PW2162, which is a fully integrated, high-efficiency 2A synchronous rectification step-down converter that operates in a wide voltage input range of 4.5V to 16V.

It controls the sound and light status of the equipment by controlling the opening and closing of the MMBT5551 transistor, thereby realizing the prompt function of the equipment status.

[0051] (8) Bluetooth antenna module: used to enhance Bluetooth communication signals and communication quality;

[0052] (9) Independent watchdog module: performs a timed reset when the program runs away or an infinite loop occurs.
