Abstract

The invention relates to an air pressure braking system. The air pressure braking system comprises a controller, an air compressor, an air supply pipe, a pressure / air power generation device, a pneumatic motor, a pneumatic power generation device, a storage battery and a storage battery management system, wherein the controller comprises a micro-processing control unit and a control electromagnetic valve. The air pressure braking system is mainly applied to a pneumatic-electric conversion and control method of a freight train. According to the pneumatic-electric conversion and control method of the freight train, an air braking signal of the air pressure braking system is converted into a voltage signal; energy is stored by using the storage battery management system; power is supplied toa control device by using an energy storage system; and therefore, the braking of the freight train is accurately controlled.

Description

technical field

[0001] The present invention relates to the field of aerodynamic power generation control of freight trains, to the field of electronically controlled air brakes, in particular to an air-electric brake system and an air-to-electricity conversion and control method for freight trains, and in particular to using the original pressure of an air supply pipe for power supply , applied to train electronically controlled air brakes. Background technique

[0002] Railway freight is developing in the direction of fast freight. In order to ensure the safety and efficiency of railway transportation, the requirements for vehicle braking systems are also increasing.

[0003] In the past, railway freight trains have always used the air brake system, but in today's express freight trains, the air brake system has shown its shortcomings: longer braking distance, insensitive adjustment of empty freight, lack of vehicle anti-skid, etc. Equipment, as well as the excessive long...
