Technical Seminar – Railway Line Control Survey and Track Geometry Survey
Track misalignment and degradation can affect passenger comfort during train operation. By utilizing technologies such as BeiDou satellite positioning and inertial measurement, precise measurement and control of the track misalignment can be achieved, thereby enhancing the quality of railway operations and safety management. This seminar will explore the construction of efficient and high-quality railway line control networks and precise track measurement systems, enabling high-quality maintenance and repair operations on metro under conditions of high tonnage and limited maintenance windows, which aims to provide convenient and efficient solutions for the maintenance and repair of intercity railways and urban rail transit systems worldwide.
Speaker
The Fifth Railway Survey and Design Institute Group Corporation, affiliated to China Railway Construction Corporation Limited, is a large-scale comprehensive survey and design enterprise with a long history, mainly engaged in survey and design, scientific research and development, technical consultation and other work in the fields of railways, urban rail transit, municipal engineering, etc. As the supporting unit of the Beidou Railway Industry Engineering Research Center of the National Railway Administration of China, the Institute can provide overall solutions ranging from the planning and design of railway precise survey networks, precision track measurement to track digital twin technology, ensuring efficient, safe, and reliable operation and maintenance of the railway system. The speaker at this symposium is Rao Xiong, the technical director of the Beidou Railway Industry Engineering Research Center and the deputy dean of the Science and Technology Institute of the Fifth Railway Survey and Design Institute Group Corporation.
