Heavy-haul railway moving block system based on wireless communication

Abstract

The invention relates to the field of rail transportation and discloses a heavy-haul railway moving block system based on wireless communication. The heavy-haul railway moving block system comprises acommunication device, a positioning device, a train-mounted control device and a wireless block center. The train-mounted control device is located on a train and used for receiving train position information from the positioning device. The communication device is connected with the train-mounted control device and used for sending the train position information. The wireless block center is located on the ground and used for receiving the train position information and sending the driving permission according to the train position information. The communication device is further used for receiving the driving permission. According to the heavy-haul railway moving block system based on wireless communication, the number of rail installation transponders can be effectively reduced, the positioning precision and efficiency of the train can be effectively improved, the maintenance cost of the rail devices is reduced, meanwhile, the availability of a positioning system under a special environment is guaranteed, and the heavy-haul railway moving block system is perfect and practical.

Description

technical field [0001] The invention relates to rail traffic, in particular to a heavy-duty railway mobile block system based on wireless communication. Background technique [0002] Blocking means that after the train enters the section, it is isolated from the outside world, and the stations at both ends of the section will no longer depart to this section to prevent trains from colliding and rear-end collisions. This was the concept of early single-track railways, now known as semi-automatic blockades. With the development of technology, railways need to increase their transportation capacity, especially after the development of single-track railways into double-track railways, the concept of automatic blockage appears, that is, the interval between two stations is divided into several block sections, and only one block is allowed in each block section. The train runs. Blocking equipment is the railway section signal equipment set up to realize "in one section (blocking...

AI Technical Summary

Problems solved by technology

[0008] In the above-mentioned train positioning scheme, balises need to be arranged every kilometer, and multiple groups of balises need to be arranged in the station. In heavy-duty railways, the running lines are long, and most of the lines are located in mountainous areas and other difficult terrain areas. The layout and maintenance of balises will cost a lot

[0009] The initial positioning of traditional mobile block trains requires two transponders to locate. In heavy-duty railways, it is dangerous for trains to move without a position, and the running speed is low, so the departure efficiency cannot be improved.
