Detailed ways

Referring to Fig. 1 and Fig. 2, the intelligent door lock system of the present invention includes two parts, a mobile terminal and an intelligent door lock. The mobile terminal is installed with a door lock control App program, and the App program is developed based on an existing common mobile phone operating system, such as an IOS operating system, Android operating system and Windows operating system, the user opens the door lock control App program, enters the account number and password to obtain control authority, and can send wireless remote control information to the smart door lock through the door lock control App program; the smart door lock receives the door lock control Wireless remote control information sent by the App program, and perform corresponding actions;

The smart door lock includes a communication module, a control module and a bolt driving mechanism:

The communication module is used to receive wireless remote control information. The communication module includes a WiFi sub-module and a ZigBee sub-module. The ZigBee sub-module is connected to the WiFi sub-module and the control module respectively. There is a ZigBee chip in the ZigBee sub-module; No., to eliminate the traditional wireless network channeling phenomenon, the WiFi sub-module and the control chip in the control module communicate with it through the protocol.
