无线传感器网络在煤矿环境监测中的应用

Application of Wireless Sensor Network in Coal Mine Environmental Monitoring

煤矿中的突发事故具有一定的随机性和不确定性。利用无线传感器网络采集矿井中的温湿度和瓦斯体积分数数据,再将这些数据通过无线网络传输到矿井上的环境监测中心,并把这些数据通过动态曲线的形式实时直观地显示出来;尤其是在被监测的瓦斯体积分数超标的时候,还可发出报警信号。采集到的数据会备份到数据库中,通过对这些数据进行科学的分析归纳,总结其中存在的规律,能为预测事故和危机的发生提供强有力的数据支持。

The accident in coal mine has a certain randomness and uncertainty. Wireless sensor networks collect temperature, humidity and gas concentration in mine, and transmit the data to the environmental monitoring center through the wireless networks, display the data through dynamic real-time curve visually; It can give out alarming signal, especially when the gas concentration detected exceeds the safety value. The collected data hack - up to the database for scientific analysis in order to summarize some subsistent rules, providing strong data support for the prediction of accidents and crisis.
