Design of Underground Wireless Sensor Network Node for Real-time Monitoring and Its Implementation

针对煤矿井下环境在线监测的要求,提出了一种井下实时监控无线传感器网络节点的设计方法,详细介绍了无线传感器网络节点的硬件组成和软件设计。该节点通过微控制器和无线传输模块实时采集、处理、传输井下工作面的瓦斯浓度、CO浓度、温度、湿度等数据。测试结果表明,该节点控制方便、工作稳定,能实现可靠的无线网络传输。

In view of request of on-line environment monitoring of coal mine underground, the paper proposed a design method of underground wireless sensor network node for real-time monitoring, introduced hardware composition and software design of the wireless sensor network node. The node can collect, process and transmit data of gas concentration, CO concentration, temperature and humidity of underground working face by microcontroller and wireless transmission module. The test result showed that the node is convenient to control and runs stably, which can realize reliable wireless network transmission.
