Access control method and system based on Bluetooth MESH networking core technology

Abstract

The invention discloses an access control method and system based on a Bluetooth MESH networking core technology. The system comprises a CPU main control chip module, a Bluetooth wireless networking module, a door lock electric control module, a keyboard input module and a power supply module. The method comprises the following steps: accessing lower-layer Bluetooth terminal equipment by utilizing Bluetooth module communication, and realizing point-to-point unlocking control and real-time feedback of door lock status information; connecting with other Bluetooth door locks and a Bluetooth gateway through the Bluetooth module communication, constructing an MESH network layer, realizing MESH route management, and carrying out information multi-hop transmission, so that a locking / unlocking control command pushed by a remote receiving server, server-side user right or door lock information change and a function of uploading local door lock status information through a Bluetooth MESH network are realized; and manually intervening unlocking by inputting a spare dynamic password by virtue of a keyboard, wherein the spare dynamic password can be set with a valid period at a server side according to the need, and safety and convenience of a door lock are guaranteed.

Description

technical field [0001] The invention relates to the field of access control systems, in particular to an access control management method and system based on the core technology of Bluetooth MESH networking. Background technique [0002] At present, in most college dormitories, traditional mechanical keys are still used as the way to open the dormitory. Every year when a large number of old students leave school, new students come in, and dormitory changes are involved, the school needs to spend a lot of energy on collecting and distributing dormitory keys, or replacing the lock cylinder, which costs a lot of manpower and material resources every year. [0003] Not only that, key management has many security holes, such as: [0004] (1) There is a lack of control over the entry and exit of each room (who, when, where, and what), and in the event of theft or personal accidents, it is impossible to verify; [0005] (2) The key is easy to be copied, and the loss cannot be rep...

AI Technical Summary

Problems solved by technology

[0004] (1) There is a lack of control over the entry and exit of each room (who, when, where, and what), and in the event of theft or personal accidents, it is impossible to verify;

[0005] (2) The key is easy to be copied, and the loss cannot be reported after being lost, and the risk is relatively high;

[0006] (3) Laboratories, training rooms, and classrooms are often used by different personnel in rotation. Even if one or two personnel manage them, they are often open, which may lead to theft or damage of valuable teaching aids;

[0007] (4) Teachers teach in multiple classrooms, laboratories, and training rooms, and it is inconvenient to carry multiple keys with them;

[0008] (5) In the dormitory, if the student forgets to bring the key, the administrator needs to accompany the administrator to open the door or lend the key to the student;

[0009] (6) In the dormitory, students often do not lock the door or forget to lock the door for convenience, and are easy to be taken advantage of;

[0010] (7) When the administrator or teacher wants to check the hygiene of the dormitory, etc., they will carry a large bunch of keys with them, which is inefficient and slow;

[0011] (8) Students lock the door of the dormitory and engage in behaviors prohibited by the school, which cannot be controlled;

[0012] (9) Whenever new students report and old students graduate and leave school, the work of collecting keys and changing lock cylinders will consume a lot of energy of the school, and the management is chaotic

[0013] Therefore, the access control system should be born. Although the traditional access control has the function of safely managing the entrance and exit, it cannot perfectly meet the needs of the school. It mainly has the following defects:

[0014] (1) There are many cables, the installation and construction are complicated, and the existing decoration needs to be destroyed, which is especially acute in the renovation project;

[0015] (2) The locks are mostly magnetic locks, which will deform when used on anti-theft doors, resulting in a decrease in suction, and long-term use on the door will cause deformation of the door;

[0016] (3) Relying on uninterrupted power supply, the system cannot be used after power failure, and the door cannot be closed normally; and the cost is high;

The main problems include: the operation of locking and unlocking is limited to a short-distance range of vision; the door lock is in an information island without a mobile phone connection, and the status information of the door lock cannot be updated synchronously; the single connection method between the door lock and the mobile phone cannot form a centralized batch management
