Intelligent access control system based on STC single-chip microcontroller and Bluetooth 4.0 communication module

Abstract

In order to solve problems that the key terminal of the existing access control system is difficult to store and easy to lose and the recognition rate is low in the prior art, the invention provides an intelligent access control system based on an STC single-chip microcontroller and a Bluetooth 4.0 communication module. The intelligent access control system includes a key terminal and a lock terminal. The key terminal is an electronic device provided with an APP program and a Bluetooth 4.0 communication module. The lock terminal includes a password inputting module, a door lock controller, anSTC single-chip microcontroller, and a Bluetooth 4.0 communication module; the STC single-chip microcontroller is in signal connection with the password inputting module and verifies and stores a password inputted by the password inputting module; the Bluetooth 4.0 communication module of the lock terminal establishes connection with the Bluetooth communication module of the key terminal. The STCsingle-chip microcontroller compares the received password with the password stored by the STC single-chip microcontroller; and the STC single-chip microcontroller sends the comparison result to the door lock controller. On the basis of the mode of combining the APP program with the Bluetooth communication technology, the door lock can be opened without a physical key and the two-way authentication of the key terminal and the lock terminal is realized through Bluetooth interaction, thereby preventing the lock terminal from being illegally opened.

Description

technical field [0001] The invention relates to an access control system, in particular to an intelligent access control system based on an STC single-chip microcomputer and a bluetooth communication module. Background technique [0002] With the rapid development of today's science and technology, the current access control system has further developed compared with the traditional access control system, and gradually formed a complete access control system. In many residential quarters, office buildings and other buildings, each user has a personal identification code formulated by the access control system. Users can pass through the access control system only with their unique passwords. Therefore, the access control system has also become a guarantee for users in the building. Necessary facilities for the safety of life and property. [0003] The predecessor of the development of the access control system is called the "electronic lock" stage. Although the appearance o...
