Abstract

A train tail safety protection wireless digital control system comprises a driver control box, a train tail main unit, a plurality of wireless routers installed on each carriage. The driver control box, the train tail main unit and the wireless routers form a wireless digital communication network, so that the problem of signal dead zones is solved, comprehensive coverage of wireless communication signals is realized, information such as wind pressure and the like relevant to a train tail and relevant control commands are reliably transmitted, and mutual interference among the train tail safety protection wireless digital control system and other communication systems is avoided by means of a 2.4GHz ISM (industrial scientific medical) band. The train tail safety protection wireless digital control system is high in cost performance, beneficial to popularization and application and capable of thoroughly solving the problems of an existing train tail safety protection device, so that train running safety is powerfully guaranteed, and transport production efficiency of trains is improved.

Description

technical field [0001] The invention relates to a train tail safety protection device, in particular to a wireless digital control system for train tail safety protection. Background technique [0002] The safety protection device at the rear of the train is an important driving equipment to ensure the safety of railway transportation. Since 2002, the entire road has implemented the project of canceling the guard at the rear of freight trains and the length of the running train, and using the safety protection device at the rear of the train to realize the functions of marking the tail of the train, checking the wind pressure, braking the exhaust, and automatically alarming the abnormal wind pressure of the supervisor. The extensive use of train tail safety protection devices on railway freight trains has saved a lot of manpower, improved transportation production efficiency, and played a very important role in ensuring train safety. With the six major speed increases o...
