Nanjing, born and thriving by water, was once known as the "Water City". The Yangtze River runs through the city, the Qinhuai River flows around the city, and rivers and lakes are scattered everywhere.

Currently, how can Nanjing better write 'water articles'? According to the "14th Five Year Plan for Water Development in Nanjing", Nanjing will focus on the overall goal of building a "happy river and lake",Accelerate the construction of a modern comprehensive guarantee system for water affairs.

In order to better build a "happy river and lake" and refine the supervision and maintenance of rivers, the Nanjing Water Facilities Management Center, a unit under the Nanjing Water Affairs Bureau, has introduced DJI Airport to conduct 7 × 24-hour unmanned automatic inspections of 7 rivers within the airport coverage area of 28 square kilometers. The focus is on AI intelligent recognition inspections of water surface garbage, construction site drainage, pump station facilities, safety facilities, and other ancillary facilities in the supervision area.

Daily monitoring:

High definition camera viewing

5G+AI intelligent recognition problem points

The Nanjing Water Facilities Management Center is mainly responsible for the river maintenance and supervision of 12 municipal districts in the city and functional areas. Traditional river inspections usually use manual hiking, which is time-consuming, laborious, and unable to fully view the river. At the same time, areas that are difficult to reach manually become blind spots for supervision.

After the introduction of DJI Airport, the staff utilizedAirport+5G+Beidou positioning+AI recognition fusion technologyTo achieve efficient inspection of river channels. DJI Airport is equipped with latitude and longitude M30T unmanned aerial vehicles. Staff use high-definition visible light zoom lenses to present detailed information about areas such as water surfaces, bank slopes, and exhaust outlets. At the same time, infrared cameras are used to monitor exhaust outlets.

After the drone collects data, it intelligently identifies problems through AI, generates work orders directly, and notifies staff to follow up and handle them in the first time, improving the speed of problem handling.

Emergency live broadcast:

Drones can take off at any time and operate automatically

Real time feedback of on-site situation

During river inspections, it is common to encounter situations such as emergency repairs of drainage facilities, urban waterlogging response, and special commemorative days. The traditional method requires personnel to be sent to the scene for inspection, which makes it difficult to achieve efficient emergency support, and is limited by the ground perspective, making it difficult to visually present individual problem points.

DJI Airport has the advantages of maneuverability, flexibility, efficiency, and intelligence, and can quickly achieve visual command and dispatch. In a sudden river incident, the staff remotely activated DJI Airport from the DJI Sikong 2 backend and controlled the drone through the "command flight" function. The drone quickly flew to the scene to conduct real-time live broadcasts of the situation, and the images were transmitted back to the water facility management center, providing important basis for remote command and decision-making.

Panoramic River VR:

Drones can easily obtain panoramic images with just one click

Overlay water facility information to assist command and decision-making

to understandmanydirectionMulti dimensional understanding of the river and surrounding environment requires obtaining a panoramic view of the river.

The drone provides a high-altitude perspective and can easily obtain a panoramic view of the river with just one click, maximizing the authenticity of the river scene and the accuracy of information. The staff use panoramic images for VR roaming, allowing them to view detailed information about the river in person. At the same time, the panoramic view can overlay relevant water facility information, so that when an emergency is detected,It can help staff have a more comprehensive understanding of their environment and make more accurate decisions.

DJI Airport conducts on-site flight inspections of rivers, dams, water facilities, etc., which not only ensures the safety of inspection personnel but also greatly improves inspection efficiency. In the face of special emergencies, DJI Airport can be remotely controlled, and drones can arrive at the scene in the first time to understand the situation and help the command center make accurate decisions.selfSince the deployment of DJI Airport, a total of 516 unmanned aerial vehicles have been flown, with an average of 4 operations per day. Any problems found have been pushed to relevant departments for resolution.

Through the "medium" of digital technology, the "quality" of regulatory development is formed. The addition of DJI Airport has brought new management models and more efficient working methods to the urban waterways of Nanjing, and has pressed the "acceleration button" for the construction of the Happy River and Lake in Nanjing.
