As a representative of the new quality of productivity, the application of low altitude economy new scene is continuing to expand. august 14, a drone in qinhuaixinhe base station airport vacated slowly took off, began to subway line 7 xishanqiao station to yongchu road north of jiangshan avenue section of the section of the line for inspection. The reporter learned that this is the first time the Nanjing subway will be applied to the subway protected area drone intelligent inspection scene, also marks the subway protected area since then there is an “air eagle eye” escort.
What is a subway protected area? “Like nature reserves that protect plants and animals, there are actually 'protected areas' hidden around the subway, and they generally refer to the area covered by 50 meters to 150 meters around the perimeter of the subway line.” Nanjing Metro Transportation Facilities Protection Office refers to the transfer (information) section deputy director Feng Lirong told reporters, in order to protect the subway structural safety and operational safety, the Nanjing Metro in the rail transit line or structure of the perimeter of a specific range, set up the subway control protection zone and special protection zone.
Reporters on the scene to see, from the base station after the takeoff of the drone, in accordance with the preset route automatically adjust the flight attitude, PTZ angle, while automatically back to the cruise captured pictures and video. “The first flight interval is roughly 6.5 kilometers long, covering 1 level A, 9 level B, 2 level 2 projects and 9 regulatory airspace, complex geographic conditions, more insurance-related projects.” Feng Lirong introduced, the subway along the line of a number of construction projects and to be developed land, if the construction unit without permission, unauthorized construction, may have an impact on the subway structure and facility safety.
Up to now, the Nanjing Metro has a total of 13 operating lines, involving 11 lines under construction, the line mileage of 671 kilometers, the scope of the radiation protection zone is gradually expanding, the daily inspection also appears to be critical.
“Things like subway station entrances and exits, within 30 meters of ground level stations, and within 50 meters of the outer edge of the outer boundary line of tunnel structures are the focus of daily guarding inspections.” Nanjing Metro Transportation Facilities Protection Office of the Protected Areas Administrative Law Enforcement Brigade team member Xu Duo is a member of the protected area inspection team, daily responsible for metro line S3 Yaofangqiao to Pingliang Street along the protected area inspection. Reporter in Xu Dao's inspection terminal system to see, within the yellow line is the track area, within the red line is a special protection zone, the outermost is the control of the protected area, these areas are her daily inspection need to focus on.
Like this operation line Xu Duo at least 3 times a week to inspect. In order to more clearly see the current situation of the protection zone, Xu Dao daily need to walk through the inspection of these may affect the subway safety of various types of risk points. “Through daily inspections, identify and control the risk points in the protected area in advance, so that the subway operation is not affected by outside construction, foreign body invasion, etc., to ensure the safety of subway operations. Once the suspected risk points are found, actively maintain communication with the relevant responsible units to eliminate the risk points in time.” Xu Duo told reporters, Yufangqiao station to Pingliang Street station is about 2.4 kilometers, one-way inspection takes at least 40 minutes, “especially in the hot weather, a circle down, uniforms from the inside to the outside are all drenched in sweat.”
After about 20 minutes, the drone inspection ended back to the landing site, and the real-time video images captured back to the background. “Compared to manual inspection takes half a day, the drone can be unmanned state regularly perform inspection tasks, at the same time, by virtue of the low-altitude flying perspective advantage, can quickly find some of the more hidden construction behavior.” Feng Lirong told reporters, in order to explore the wisdom of means to assist the traditional manual inspection methods to increase efficiency and optimize the realization of the protected area supervision mode upgrade, “the next will rely on the wisdom of the background embedded AI algorithm recognition technology, so that the drone automatically identify the protected area piling equipment, excavators and other high-risk machinery and construction violations, to achieve the real-time analysis of the drone supervision screen and timely warning! , forming a closed-loop management mode of 'intelligent inspection - intelligent warning - scientific dispatch - emergency disposal'.”
Nanjing metro relevant person in charge said, will continue to grasp the opportunity of low altitude economic development, play rail transportation industry chain resource advantages, will further expand the pilot application of drone intelligent inspection in Nanjing metro protected area.
