采空区无线温度传感网络的通信系统设计

Communication System Design of Wireless Temperature Sensing Network in Goaf

在充分研究采空区煤炭自燃的监测方法后,确定了以温度作为监测煤炭自燃发生的指标,采空区环境复杂,干扰较多,对于采空区的通信系统性能要求较高。Zig Bee无线通信系统覆盖面广,抗干扰能力强,利用Zig Bee无线通信技术建立了采空区无线温度传感网络的通信系统。此通信系统主要由发射端、信道和接收端组成,通过测试某煤矿采空区的温度变化验证了此通信系统的信息传输性能良好。

After fully studying the monitoring method of spontaneous combustion in goal, it is determined that the temperature is the indicator to monitor the occurrence of coal spontaneous combustion. The environment of goaf is complex and there is a lot of interference, so high performance for the communication systemis requi-redingoaf. ZigBee wireless communication system covers a wide range andhas strong anti-interference ability, so ZigBee wireless communication technology is used to establish wireless temperature sensor network communi-cation system in goaf. The communication system is mainly composed of transmitting terminal, channel and receiving terminal. The transmission performance of this communication system is verified by testing the temper-ature change of a coal mine goaf.
