Research On Monitoring System Of Underground Pipe Gallery

With the rapid development of China's economy,the construction of urban public infrastructure has been greatly developed.Underground pipe corridor integrates municipal,electric power,communication,gas,heat,water supply,drainage,fire protection and other pipelines into the underground tunnel of urban roads,which can be used for maintenance and maintenance of various pipelines inside the pipe corridor,avoiding traffic interruption and urban appearance damage caused by repeated road excavation and dense overhead line network.Underground pipe corridor is closely related to national economy and people's life.In order to ensure the safety of pipe corridor,real-time and automatic monitoring of its internal environment is required.The underground pipe corridor monitoring system designed in this paper realizes the automatic monitoring of pipe corridor temperature,humidity,oxygen concentration,harmful gas concentration,water depth,external biological invasion,pipeline leakage and other information,as well as the location of leakage point of water supply pipeline and fire prediction,which provides a guarantee for the safe operation of underground pipe corridor.This paper analyzes the underground pipe rack monitoring work environment,functional requirements and monitoring system was proposed based on Internet of overall scheme of utility tunnel monitoring system,mainly for environmental parameters monitoring has made the detailed design of the monitoring system of data acquisition module,data transmission module,data processing module,data storage module,human-computer interaction module of hardware,software design,realized the utility tunnel temperature,humidity,oxygen concentration and the concentration of harmful gases,water depth and external biological invasion and automatic monitoring of pipeline leak,using multi-sensor information fusion technology for underground utility tunnel fire,The leakage point of water supply pipeline is located by cross-correlation principle.The function of the system was tested and the expected goal was achieved.
