Intelligent access control system and control method

Abstract

The invention discloses an intelligent access control system and a control method. The system comprises a power supply, a microcontroller, a bluetooth module, a wireless internet access module, a datatransmission module and a door lock control module. The power supply, the bluetooth module, the wireless internet access module, the data transmission module and the door lock control module are allconnected to the microcontroller. The intelligent access control system searches for bluetooth signals, automatically judges the distance from a mobile phone and the access control system after havingresearched an authorized bluetooth signal, and automatically opens the gate when the distance reaches a threshold value. The intelligent access control system supports mobile phone unlocking. Users don't need to equip special-purpose terminal equipment, and there is no need to install any APP on a mobile phone of a user for unlocking. In addition, user operation is simple, and the user only needsto open the bluetooth of a mobile phone and arrange the bluetooth to be visible. The opening of a door is also automatically controlled by the system, and users don't need to do any operation. The system of the invention is convenient and efficient.

Description

technical field [0001] The invention relates to the field of intelligent security technology, in particular to a control system and a control method for intelligent access control. Background technique [0002] With the rapid development of the mobile Internet, more and more intelligent devices have entered our lives, bringing us great convenience in all aspects of life.

[0003] At present, the industry uses the mobile phone Bluetooth to open the door, which is connected to the access control system through the mobile APP, and then the user completes the door opening operation. Although the smart access control is realized in this way, the user needs to install the APP on the mobile phone, and the APP needs to be opened before opening the door. Open the door The steps are more complicated. In addition, in places with poor signals such as elevators, the mobile phone may not be able to open the door due to no signal, which affects the normal access of users.
