The marshalling station is mainly engaged in the marshalling and disintegration of freight trains in railway stations. The North Marshalling Station in Chengdu is closest to us. With the development of China's railways, wireless communication technology has been widely used in the railway field. This paper first puts forward the scope and basis of the research, and then provides us with a systematic

This paper focuses on the application of wireless communication technology and LED display screen in the train wireless plane adjustment system, analyzes the feasibility and practicability of the system, and deeply studies the application of wireless communication technology. The paper also introduces the design principle and process in detail, and briefly introduces the device selection and management in the design of led display subsystem. This paper also carefully considers the selection of system equipment, and demonstrates its important role with a small case, further explaining the feasibility and advantages of wireless communication technology applied to marshalling stations. Finally, the design experience, economic value and application prospect of wireless plane adjustment system are summarized. Different from other research papers on wireless communication technology, this paper includes the analysis of LED display system design.
