地下管网主要包括下水道、化粪池等。由于管道内通风不良,造成可擦气体积累,当可燃气体浓度积累到爆炸限时,遇到明火则可能爆炸。本文针对下水道频繁爆炸的问题设计了地下管网气体危险源监控预警终端,该终端是地下管网气体危险源监控系统的一部分,、本监控系统由监控中心、通信网络和监控终端三部分组成?本监控终端实现了可燃、有毒有害气体的在线监测,减少了爆炸事故的发生。
Underground pipe network mainly includes sewers, septic tanks and so on. Due to poor ventilation in the pipeline, resulting in the accumulation of erasable gas, when the concentration of combustible gas accumulated to the explosion limit, the case of open flame may explode. In this paper, aiming at the problem of frequent explosion of sewer, a monitoring and warning terminal of underground pipeline gas hazard monitoring was designed. The terminal is a part of monitoring system of underground pipeline gas hazard. The monitoring system consists of monitoring center, communication network and monitoring terminal. The monitoring terminal to achieve flammable, toxic and harmful gases online monitoring, reducing the incidence of explosions.
