Design of Campus Security Information Identification System Based on ZigBee and CC2530 Module

With the development of information technology, more and more big data and Internet of Things related technologies have begun to integrate into the construction of campus information, and the construction of campus security information identification system is developing in the direction of automatic, intelligent, sharing and linkage. In this study, the intelligent campus security information needs are investigated, and the campus security system based on the Internet of Things is designed, and the overall design scheme is proposed. CC2530 chip is selected to be responsible for data processing and communication coordination. The main idea is to sense the environment through various terminal modules, that is, temperature sensors, smoke detection sensors, etc. Sensor nodes and coordination nodes independently establish a wireless local area network based on ZigBee protocol, and the sensor module in the sensor nodes distributed on the campus begins to power on and collect environment and security information continuously. The sensing node sends the detected information to the coordination node through multicast mode, and then the coordination node sends the detected information to the back-end control gateway through the serial port. STM32 displays security detection information through the TFT LCD module, which is processed by the system administrator; When the monitoring indicators exceed the normal range, the remote alarm function will be activated, and the back-end control gateway will send alarm information to the Android client.
