The utility tunnel is an underground aorta of the whole city, so perfect consideration and strict design must be carried out. When the detection equipment is selected, corresponding technical specification requirements should be referred to, such as GB50838 and 2015 technical Specification for urban comprehensive pipe gallery, GB50264 design Specification for industrial equipment and pipeline insulation engineering, and GBZ/T205 Specification for occupational hazard protection in enclosed space operation. According to the requirement of the specification, when the utility tunnel monitoring alarm system is designed, the control equipment in the pipe gallery is mainly divided into three types: lighting equipment (being convenient for inspect), fan equipment, fire control aggregate unit. In the above specifications, it is provided that for condition monitoring and control of ventilation equipment, drain pumps, electrical equipment, etc., the equipment control is preferably performed by in-situ manual, in-situ automatic and remote control. In the system, the invention mainly aims at pipeline and environment monitoring alarm and operation and maintenance management, can realize remote data monitoring and timely alarm, can lock the area in time after abnormity occurs, and can process in time after analysis to complete corresponding operation and maintenance work.

In the above-mentioned pipeline and environmental monitoring, in addition to the monitored temperature and humidity, more important are the necessary gas concentrations, such as methane, H, which may occur in gas pipelines in underground pipelines2S, etc., organic matters in the drainage pipeline are decomposed to generate a large amount of methane and H2S, once leakage occurs, the combustible gas content in the air increases significantly, with the greatest possibility of danger.
