A DESIGN OF WSN BASED LOCKING SYSTEM

This paper studied and designed a smart lock based on STM32F4 and CC2530 wireless module and proposed the overall design scheme of the system. By utilize the wireless transmission characteristics of ZigBee module, we can make the STM32F4 as the main control chip, and CC2530 as the wireless transmission module to realize the control of smart door lock. The smart lock consists of a smart lock device and a CC2530 wireless transmission module. The structure of the intelligent lock device mainly includes the module of door lock control chip, monitoring module, lock tongue drive module and power supply circuit. The intelligent lock device uses the STM32F4 microcontroller as the door lock control chip, sends an unlock instruction to the CC2530 module A by using the USART serial port, and then sends the received instruction to the CC2530 module B connected with the smart lock by the CC2530 module A. Control the opening and closing of the smart lock device.
