Clairvoyant in the air, the new "guardian Spirit" of Nanjing Section of Yangtze River

In order to further improve the digital information level of river water administration in Nanjing section of the Yangtze River and enhance the response ability of rapid maneuvers, Nanjing Yangtze River River Administration Office innovatively introduced UAV inspection methods on the basis of traditional inspection methods, realized convenient, dynamic, efficient and fine management, and effectively maintained the effectiveness of river management in Nanjing section of the Yangtze River.

During the on-site inspection, the staff, with a large screen remote control in hand, focused on the operation of a white drone to observe and monitor dikes, flood control works and their attached facilities within the scope of the Yangtze River management, projects occupied by enterprises and public institutions along the river, projects under construction along the river, and the protection area of the water source area along the river. At the same time, the screen on the remote control and the monitor of the external portable computer can clearly receive the images and monitoring data transmitted by the drone in real time.

According to the staff, the dispatched UAV, equipped with high-definition monitoring probe, can realize the remote image photography and camera function, in addition to the normal river management scope of static equipment and facilities monitoring, for a variety of hazards to the river safety of dynamic illegal behavior, can be found in time and remote forensics, to ensure accurate information in law enforcement action, rapid response, Save manpower, material and financial resources to a greater extent. In addition, it can also monitor the water environment in the monitoring area, accumulate analysis data through regular inspection, provide auxiliary decision-making for water environment governance, and effectively ensure the safety of water source.

"Currently, the Nanjing section of the Yangtze River has a long coastline and wide beachlands, which occupy project sites in multiple areas and uneven distribution. While the water administration patrol team is short of manpower, drones can not only effectively make up for the shortage of manpower, but also penetrate into hidden areas for surveillance." Nanjing Yangtze River management Office relevant person in charge of the introduction, "with the UAV patrol assistance, the staff is not subject to the constraints of time, space and terrain conditions, give full play to the flexibility of the UAV, mobility, safety and other advantages, rapid positioning, timely lock the illegal evidence, effectively avoid the scene environment and human factors interference, fast and efficient investigation of river water violations, Improve river inspection efficiency."

It is reported that the UAV inspection of the Nanjing section of the Yangtze River has been used in water administration law enforcement inspection, illegal sand mining in the river, flood control and rescue auxiliary command of the river, environmental monitoring of the water source along the river, supervision of projects under construction, supervision of shoreline remediation action and many other aspects. In 2019, more than 100 unmanned aerial vehicles were deployed to patrol the Yangtze River in Nanjing, and more than 20 cases of rectification were found, covering a total distance of more than 2,000 kilometers.

"By comparing and analyzing the high-resolution ground images taken by the drones, we can easily find new illegal activities on both sides of the river, such as new construction and garbage piling. In the past, some illegal construction, stacking located in complex terrain, hidden bank section, manual inspection is difficult to find. Unmanned aerial vehicle inspection is a clairvoyant inspection job. Now, it takes only a few hours to complete the inspection task, which used to take several days. Nanjing Yangtze River management Office relevant person delighted to tell reporters. Nanjing Yangtze River Channel Management Office takes advantage of the advantages of UAV inspection, such as fast information acquisition speed, wide inspection and monitoring range, and high data analysis accuracy, which effectively makes up for the shortage of patrol manpower, difficult access to blind areas and dead corners, lagging data processing and so on. Compared with the traditional inspection method, the work efficiency and effectiveness have been significantly improved. It further upgraded the modernization level of inspection and supervision in the scope of river management in Nanjing section of the Yangtze River, and created a new mode of "science and technology + inspection" in river management.
