In recent years, news reports have occurred a number of high-rise building facade or tile shedding incidents, resulting in casualties, causing social concern. The relevant departments of Hongkou District attach great importance to this. The pilot project adopts the technology of "5 G+ UAV + infrared thermal imaging "to carry out physical examination of high-rise buildings such as Lanqiao Building in North Bund Street, Yongde, Zhengxing Community, Quyang Road Street Post and Telecommunications Village in the area of jurisdiction, so as to eliminate the hidden dangers of falling off the facade of tall buildings and ensure the safety of the public.

At present, the design life of high-rise buildings (residential and office buildings) in our country is generally not less than 50 years, but due to the lack of regular inspection, maintenance, maintenance and repair and treatment of the initial diseases of the high-rise buildings, a large number of high-rise buildings will appear more serious leakage, external wall insulation materials or finishing materials shell, detachment and other diseases after 5-8 years of operation.

Since last year, Hongkou District in Shanghai has used drones to "check up" some high-rise buildings in the region, and to timely rectify and repair high-rise buildings that have found hidden safety problems. After analyzing the infrared image of Lanqiao building exterior wall taken by the UAV, Hongkou District found that there are a large number of abandoned air conditioning wall holes without waterproof sealing treatment or the holes in the wall connection of the outside air conditioner support, and the problems of cracking, shelling and detachment of exterior wall tiles may be caused by freeze-thaw and rust expansion damage caused by leakage.

To this end, the relevant departments immediately found the problem information, immediately feedback to the property department, time-limited rectification and repair. Through the cooperation of various departments and units, the outer facade of Lanqiao Building has been repaired and the hidden dangers of safety have been eliminated. "The use of drones for high-rise buildings'physical examination, timely detection of hidden dangers and to deal with, this has achieved good results ". Hongkou District City Transportation Center responsible person said that the traditional use of manual investigation, low efficiency, it is difficult to accurately find the problem and timely disposal. Now the introduction of "5 G+ UAV + infrared imaging "technology to inspect and detect the exterior walls of tall buildings can greatly improve the efficiency and reduce the cost of manpower and time, and promote the fine management and modern governance of the city.

A multi-rotor drone has circled over the Yongde and Zhengxing communities on the North Road of Sichuan Province. The surrounding area has a "panoramic view" of houses, and has passed through high-definition cameras, infrared thermal imaging technology, low-delay transmission capabilities, and returned video images. Hongkou District Urban Management Law Enforcement Bureau Sichuan North Road Street team members are seriously analyzing the video screen ," these blue objects should be colored steel plates, suspected of illegal construction ," some members said. The head of the team immediately informed the property to carry out operations to deal with.

5G UAV inspection, greatly improve the efficiency of inspection of illegal buildings. In the past, people rarely checked the facade of houses, even if the inspection, but also by the naked eye, it is easy to exist blind areas. Using 5 G+ UAV to + airborne infrared thermal imager, the damage to the outer facade of the house is clear at a glance, which makes up for the defects of the naked eye, especially the illegal buildings on some buildings, which will show the original form under the inspection of the UAV. "Through drones, our approach becomes three-dimensional, filling up air power, thereby helping us to improve the efficiency of inspections, more rapid detection of illegal buildings, and more energy to solve problems ." Sichuan North Road Street City Management team responsible person said.


The problem of falling off the facade or tile of high-rise buildings has been puzzling the public. In order to eliminate such hidden dangers, since last year, Hongkou District has introduced the "5 G+ UAV + infrared imaging "technology to scan the exterior walls and check hidden dangers for some high-rise residential buildings. After testing, Hongkou District has repaired some of the buildings found problems and eliminated hidden dangers in the bud. "This year Hongkou will continue to use the'5 G+ UAV + infrared imaging' technology, for high-rise buildings'physical examination, to achieve fine management, to protect the safety of the public ". Hongkou District City Transportation Center responsible person said.

Actually ,5 G UAV technology has a wide range of applications, bridge detection, traffic monitoring, river inspection and so on have its broad stage. With the development of 5 G, digital governance means to build a solid safety net for residents' lives.
