Abstract: In order to ensure the safety of construction and transportation, implement the overall consideration, coordination and order of railway track area dispatching, this article studied and designed the construction and dispatching system in railway track area. Combined with Beidou positioning, radio frequency, station graphics and other technical means, the system implemented the management of construction plan, construction request point, dispatching order and track laying project progress in the railway track area, provided powerful management means and reference basis for the personnel in the dispatching center, and helped the construction unit to reasonably arrange the construction organization and driving organization. It has been proved that the system has solved some outstanding problems, such as the large span of operation management in the railway track area, the high level of safety requirements for traffic construction dispatching, the difficulty of early warning and pre-control of work safety, and the lack of management in the whole process.
