Intelligent drainage is based on big data+online monitoring+digital hydraulic and water quality models, intelligent management and analysis of multi-source urban drainage data, auxiliary drainage design, planning and evaluation in the business application layer, and professional applications such as unified management of facilities, intelligent perception, intelligent early warning analysis, operation and maintenance, and emergency command and dispatching management.
With the rapid development of urbanization, the construction of urban drainage and waterlogging prevention system has not kept up with the pace of urban development, and there are still weak links such as insufficient disaster prediction and early warning capacity, imperfect management system and mechanism, and lagging drainage and waterlogging prevention planning. The direct economic loss and indirect loss brought by rainstorm and flood to the city are huge.
Due to insufficient scale of drainage pipe network, mixed connection and wrong connection, damage and defects, etc., The function of some pipelines to collect and transport rainwater and sewage is reduced, resulting in sewage overflow, rainwater and sewage can not "act on their own", causing pollution to urban water bodies, seriously affecting people's living environment and health.
Intelligent drainage and waterlogging prevention is based on the detection and positioning of underground drainage facilities, pipeline detection and hidden danger troubleshooting, real-time monitoring and perception of pipeline damage and other failures, to build a comprehensive information platform for the full life cycle management of drainage pipe networks, to timely warn and deal with underground pipeline abnormalities, and to ensure the safety of people's lives and property.
01 Detection
Carry out general survey of drainage pipe network and accessories according to relevant national and industrial standards, find out the current situation of drainage pipe network and facilities, and establish a basic database of drainage pipe network and facilities after data standardization; Use the drainage pipe network detection technology to check the drainage pipe network defects, form the drainage pipe network defect list and evaluation report, establish the defect database, and provide basic data support for smart drainage applications.

02 Facility management
Realize the unified management and update of element information of each constituent unit of "source, station, network, plant, river" from the source to the end, establish the "information, account book" management mode, provide an interactive system for data management, display, statistical analysis and scientific decision-making of drainage facilities, and play the role of drainage network information in urban planning, construction, operation and management.
03 IOT perception
According to the actual needs of sewage treatment, waterlogging prevention, black and odorous water treatment, etc IOT monitoring equipment such as water quality, flow, liquid level, rainfall and video shall be deployed in sewage plants, pumping stations, key nodes of pipe networks, hidden danger points, waterlogging prone points and drainage households, and IOT sensor networks covering "plants, stations and networks" shall be established to achieve long-term dynamic monitoring, improve the operation efficiency of drainage facilities and master the operation of drainage facilities.
04 Business Management
Build a business and work collaboration platform to achieve drainage planning and status quo "one map" management; Standardize the drainage permit process and realize the online management of drainage permit; Uniformly manage all kinds of information in the whole process of project construction, and supervise the implementation of quality and efficiency improvement projects; Reasonably divide the drainage units, supervise the implementation of the long-term mechanism of daily operation and maintenance management, form a smart drainage whole process management system, provide information application services for urban drainage business management, and optimize the drainage business management process.
05 Auxiliary decision-making
The digital model of urban drainage is established to provide simulation data support for the overall design of drainage pipe network engineering, urban waterlogging prevention, and sewage treatment quality and efficiency improvement; Through the big data visualization system, the urban drainage system is systematically evaluated, and the key information in each information system is summarized to realize the overall supervision and comprehensive evaluation of drainage and sewage treatment, assist managers to understand the current situation of drainage system and improve the scientific management level.
