Train wireless electric pneumatic breaking control system and control method thereof

Abstract

The invention discloses a train wireless electric pneumatic breaking control system and a control method thereof. The train wireless electric pneumatic breaking control system is composed of a plurality of wireless electric pneumatic breaking control devices which are respectively installed into different vehicles of a train, and the plurality of wireless electric pneumatic breaking control devices in the same train build an independent wireless ad hoc network; each wireless electric pneumatic breaking control device is a wireless network node, the wireless electric pneumatic breaking control devices are in electric connection with vehicular power generators, and the gas circuits of the wireless electric pneumatic breaking control devices are communicated with air brake pipes of the vehicles. According to the train wireless electric pneumatic breaking control system and the control method thereof, the wireless electric pneumatic breaking control device closest to the front end of the train automatically fetches train braking control information from barometric changes of a vehicle brake pipe, and transfers air brake control information into radio signals, the radio signals are transmitted to other wireless electric pneumatic breaking control devices installed in the train through the wireless ad hoc network, and rapid air-filling and air-exhausting are conducted on the vehicle brake pipes, so that the speed of transmitting braking control information is improved, and the consistency of brake mitigation actions of the vehicles is improved.

Description

technical field [0001] The invention belongs to the technical field of railway train brake control, and in particular relates to a train wireless air brake control system and a control method thereof. Background technique [0002] Existing railway trains mainly use a pure air brake system, that is, the brake control is performed by using the pressure change of the brake pipe and the air brake control valve air path. Since the pure air brake transmits the braking information by the pressure fluctuation of the brake pipe, the wave speed is low, and the rear vehicles in the train have a long delay in obtaining the braking information, and the brake control valves of the front and rear rolling stock are driven by the brake pipe pressure wave to generate The braking action time of the brake system varies greatly, and the synchronization is poor. The greater the vehicle axle load, the longer the train formation, the greater the internal longitudinal force of the train caused by b...

AI Technical Summary

Problems solved by technology

Since the pure air brake transmits the braking information by the pressure fluctuation of the brake pipe, the wave speed is low, and the rear vehicle in the train has a long delay in obtaining the braking information, and the brake control valve of the front and rear rolling stock is driven by the brake pipe pressure wave to generate There is a large difference in braking action time and poor synchronization

The greater the vehicle axle load, the longer the train formation, the greater the internal longitudinal force of the train caused by braking, the greater the impact force on the rolling stock and the line, the greater the damage, and the risk of broken hooks and derailment
