Sensor application: build a comprehensive underground pipe gallery intelligent monitoring system
The comprehensive pipeline corridor is generally built underground in the city to accommodate two or more types of urban engineering pipelines and ancillary facilities, and the municipal public pipelines such as electricity, tap water, heat, gas, telecommunications and network are laid centrally in the same structure according to the planning requirements, and the municipal public tunnel space with unified design, construction and management is implemented. It also has the functions of drainage, ventilation, lighting, communication and monitoring.
The main function of the comprehensive pipe gallery is to avoid repeated excavation of urban roads, reduce urban pollution, provide various energy and communications for urban operation, and ensure urban operation.
Whether the pipeline carried by the pipe gallery or its own ancillary equipment fails, it may cause the paralysis of some functions, so it is necessary to set up various sensors to monitor and control the operation of the internal facilities of the pipe gallery when building the comprehensive pipe gallery. It generally includes: auxiliary ground and internal power supply system, lighting system, fire fighting system, drainage and smoke exhaust system, ambient temperature and humidity, combustible gas detection, access control, intrusion detection, video, patrol, etc.
Based on sensor technology, Internet of Things communication technology, pipe gallery platform monitoring and control terminal, can achieve real-time monitoring of toxic and harmful gases, temperature and humidity, water pressure and other data in the urban intelligent pipe gallery environment, through the cloud platform, Internet of Things, staff can remotely view the real-time value of the monitoring data in the pipe gallery, timely access to information, once found abnormal. Avoid causing major accidents and disasters.
Long-term semi-closed pipe gallery, long-term fermentation of urban sewage and pipe gallery sump, may produce a certain amount of hydrogen sulfide, methane and carbon monoxide, accumulated over time, may also form hidden dangers. In daily management, it is also necessary to detect these gases which are harmful to human health.
