1. Underground pipeline network, background of underground monitoring industry
The underground pipeline network is the lifeline of the city. In recent years, with the rapid development of cities, some places have experienced safety accidents such as water supply, drainage, gas, and heat pipeline leaks due to the relatively backward management level and technical means of underground pipeline networks, directly affecting the safety of people's lives and property and the safety of urban operation. In 2013, the State Council issued the "Opinions on Strengthening Urban Infrastructure Construction" (Guofa [2013] No. 36), and in 2014, the General Office of the State Council issued the "Guiding Opinions on Strengthening the Management of Urban Underground Pipeline Construction" (Guobanfa [2014] No. 27), emphasizing the conduct of urban underground pipeline surveys, the establishment of a comprehensive management information system for underground pipelines, meeting the needs of urban planning, construction, operation, and emergency response, and ensuring the safety of urban operation. In 2014, the Ministry of Housing and Urban Rural Development and six other departments jointly issued a notice to deploy and promote the survey of urban underground pipelines and the construction of comprehensive management information systems.
In the context of the promotion of the national "Internet plus" development strategy, there is no doubt that using the "Internet plus" thinking to carry out the informatization construction of urban pipe network safety operation management will become a new important topic. At present, modern information technologies such as Geographic Information Systems (GIS), Building Information Modeling (BIM), Internet of Things, cloud computing, big data, and Beidou high-precision positioning have been utilized in developed regions of China to construct safety operation monitoring systems for urban management. These systems have played an extremely significant role in environmental governance, transportation, public safety, emergency relief, and municipal law enforcement.
By utilizing the construction experience of safety operation monitoring systems in these areas and implementing IoT, real-time, and intelligent management through urban pipeline networks, the management level of urban pipeline network safety operation guarantee can be greatly improved, work efficiency can be enhanced, energy conservation and consumption reduction can be achieved, and significant economic and social benefits can be achieved.
2. The main purpose and problems to be solved in the underground pipeline network and underground monitoring industry
Integrate data on the safe operation of urban underground pipelines, coordinate the construction of underground pipeline safety operation monitoring systems with various professional pipeline management, digital city management, urban construction archives, and smart city management information platforms, and solve problems such as business segmentation and information silos.
Focusing on the construction of accident prevention, disaster prevention, and emergency response capabilities for important pipelines, key areas, and key parts, expanding the scope and content of underground pipeline monitoring, and improving the level of urban planning, construction, and management services.
Establish a working mechanism led by the government, coordinated by departments, and linked by pipeline property rights units, build a management system that coordinates comprehensive monitoring, industry monitoring, and regional monitoring, and comprehensively implement the operation and maintenance, safety investigation, and hidden danger elimination of underground pipeline networks.
3. Underground pipeline network, different types of sensors involved in the underground monitoring industry
(1) Drainage pipe network monitoring system: The drainage pipe network monitoring system realizes the monitoring and management of basic information and operating status of urban drainage pipe network online monitoring facilities. The monitoring device can collect data such as pipe network pressure, flow rate, and flow direction, support regular reporting and monitoring data over limit reporting, and can query real-time liquid level, flow rate, and other information of pipe network monitoring points. The monitoring device is mainly used for flow monitoring of domestic sewage, combined sewage or rainwater pipe networks. There are multiple composite technology sensors to choose from, and the combination of these monitoring technologies provides users with a multi-purpose monitoring platform.
