In daily railway inspection, large to a bridge, small to a screw, need to invest a lot of manpower and equipment. In particular, problems such as difficult operation of existing railway lines, difficult investigation in the field and mountainous areas, and difficult traceability of construction process management have caused too much trouble to operators. Can we solve these problems with non-contact sensing of drones? The reporter learned from China Railway Design Group Co., LTD. (abbreviated as China Railway Design), recently, the China Railway Design Surveying and Mapping Institute "based on UAV + intelligent sensing technology railway engineering comprehensive patrol application research" won the group's scientific and technological progress special prize. This research solves the problem of uav "on-line", and through the implementation of uav intelligent line patrol, it is accurate, fast and convenient.
Railway infrastructure equipment has the characteristics of many points, line length and large quantity. Existing railway lines uav operation has been the railway surveying and mapping of the area, the main reason is the uav flying above the railways are some drops hidden danger, to railways are top flight, but also to obtain the flight data meet the precision requirement, scientific research personnel through many experiments, created the existing drones side "sugar-coated berry" flight, The data are obtained from multiple angles on both sides of the existing railway line one by one, which avoids the flight operation of UAV directly above the railway, improves the observation Angle and ensures the accuracy of measurement. "Photos, videos and other inspection data taken by drones patrolling the site can be automatically sent back to the control center, and the background software can realize automatic comparison and recognition." Pointing to a cluster of bolts on a bridge, Wang Kai, an engineer at the Institute of Surveying and Mapping of China Railway Engineering Institute, said that in the past, accurate detection could not be achieved simply by using telescopes. Now even the smallest problems, as little as a centimeter of rust or a bolt falling off, can be detected.
In recent years, the video location and management of UAV railway patrol has been perplexing industry applications. After in-depth research, the research team of China Railway Engineering Has proposed a new method of UAV video positioning, which has realized the rapid positioning and integration of railway line patrol video and railway thematic information. Users can intuitively view the route direction and mileage position in the video through the system software. "Our scientific research team designed and built the uav railway integrated patrol application system by using cloud computing technology, realizing the cloud storage and management of uav video, direct projection, panoramic image, tilt model and other multi-source data, and realizing the integration of web and mobile applications." Wang kai introduced that uav +5G technology has been used to realize the remote live broadcasting of UAV video to meet railway emergency applications. based on the system platform, the application modules of expropriation and demolition project progress management, dangerous rock falling detection, filling and excavation amount analysis and other application modules have been developed, and a professional application platform with independent intellectual property rights has been built.
