Abstract
According to the records that the too-high temperature rise of equipment leaded to accidents easily, the temperature monitoring system based on ZigBee and GPRS, RS232 technology is designed. The perception layer uses the heterogeneous network topology by adding appropriate heterogeneous nodes to ordinary ones, which are much better than the ordinary in computing power, storage capacity, etc, and this topology structure extends transmission distance. Both of them use CC2530 chips, and the heterogeneous nodes are not only responsible for collecting temperature data, but also responsible for forwarding data from ordinary nodes. The sink nodes send alarm messages to staff by GPRS, and forward data from heterogeneous nodes to a PC via RS232. The system uses Visual Studio for software design to realize the function of data processing, display and storage, in order to achieve real-time monitoring of substation equipment and early warning.
