Qinhuai River Management Office: With the help of high-tech means to improve the river management level of refinement

In the face of the new situation and new characteristics of the development of Qinhuai River management, under the leadership of Nanjing Water Resources Bureau, Nanjing Qinhuai River Management Office, as the management unit of Qinhuai River, keeps pace with The Times, improves the refinement level of river management by means of the Internet of Things, big data and other high-tech means, and delivers a satisfactory water management answer sheet.

The Municipal Qin Administration Department is in charge of 22.2 kilometers from Dongshan Bridge of Qinhuai River to Xiaguan Bridge (excluding Wudingmen control gate section), 15.13 kilometers from Xinlao estuary of Qinhuai River to Xinhe control Gate, with a total length of 37.33 kilometers. In view of the current situation that the existing staffing strength and inspection effectiveness cannot meet the requirements of river management, and the backward maintenance (cleaning) operation mode is difficult to adapt to the high standard of urban river environment, the Municipal Qin Administration Office makes full use of the Internet of Things and 5G technology to realize the interconnection of river facilities and fully perceive the dynamics of the river. Accurately perceive the changes of river pile position, and find the violation of river regulations in the first time. The intelligent video camera can not only record the dynamic changes of the river course in the whole process, but also identify suspected illegal acts invading the river range and provide early warning tips.

Big data analysis technology is used to analyze the subtle changes of the river course and the activities of the dike personnel. For example, the UAV or remote sensing aerial photography is used to compare and analyze the subtle changes of the river, and find the increase or decrease of floating objects on the river surface, the change of levee greening, whether there is illegal planting, and the relevant progress of river-related projects. Through the activity thermal map of dike personnel, the activity situation of a certain period of time can be analyzed and the input ratio of maintenance and cleaning personnel can be obtained.

Artificial intelligence technology is used to help the river maintenance operation. Artificial intelligence equipment such as unmanned cleaning ship and unmanned sweeper is developing continuously, which overcomes the disadvantages of traditional maintenance mode, implements uninterrupted river operation, and disposes of adverse factors such as weather and emotion.

A new mode is explored in river management. With the help of "Smart Nanjing" city comprehensive perception platform, Phase II construction is divided into sensing equipment layer, network layer, unified basic platform layer and application layer. The Qinhuai River channel supervision plate is a unified basic platform layer, including river water quality monitoring, water surface environment monitoring, dike video monitoring and data analysis and display system. 20 sets of special spherical cameras were installed and deployed at the main outfall, construction site and high incidence of illegal dumping of garbage in the new River of Qinhuai River and the outer Qinhuai River. Through docking with the municipal public security information system, the platform provided the existing monitoring data along the river for the use of river management, which made a breakthrough in the river data acquisition of the Municipal Qin Administration Office. Daily maintenance of embankments, treatment of illegal construction, maintenance and reinforcement of embankments, supervision of river-related projects, flood control materials and facilities along rivers and other river management scenarios have been realized.

With the development of modern technologies such as the Internet of Things, big data and artificial intelligence, it provides a solid guarantee for realizing real-time control of river dynamics, carrying out fine management of river embankments and constructing new river management modes. The Municipal Qin Administration Office will adhere to the information thinking, take top planning, step by step implementation and gradual improvement as the principle, actively promote the implementation of the "Smart Nanjing" project, carry out innovative exploration of river management dimension, improve the quality and effectiveness of river management, and make positive contributions to the construction of "innovative city and beautiful ancient capital".
