为防止下水道可燃气体积聚引发爆炸事故,利用无线传感器网络技术设计了市政下水道可燃气体监测系统。实测结果表明:气体传感器监测数据相对误差在2.0%以内,无线数据收发设备的年发送成功率达到98.0%,满足工程运用需求,系统具有较高的可靠性和稳定性。结合无线网络覆盖范围广、实时在线的特点,该系统实现了对不同区域下水道内可燃气体浓度的远程监测,为下水道的安全预警提供了有效依据。
In order to prevent the accumulation of combustible gas in sewer caused the explosion accident, the municipal sewer combustible gas monitoring system was designed by using wireless sensor network technology. The measured results show that the relative error of gas sensor monitoring data is less than 2.0% and the success rate of wireless data transceiving equipment is 98.0%. The system meets the requirements of engineering application and the system has high reliability and stability. Combined with the wide coverage and real-time online coverage of wireless network, this system realizes the remote monitoring of combustible gas concentration in sewers in different areas and provides an effective basis for sewer security warning.
