Train brake release system and train

Abstract

The invention discloses a train brake release system, and further discloses a train provided with the train brake release system. The train brake release system comprises an external input port for introducing compressed gas, a gas brake release device, an electronic type brake release device and a loop switching valve. The input end of the gas brake release device is connected with the output endof the external output port, and the gas brake release device is used for outputting the compressed gas when the compressed gas flowing through has preset air pressure, the electronic type brake release device adjusts original brake pressure according to a received brake release signal and obtains brake pressure after the adjustment, and the loop switching valve is connected with the electronic type brake release device or the gas brake release device according to the actual operating state of the train. The train brake release system can significantly improve the efficiency of brake release,does not require to waste expensive manpower, greatly reduces the probability of accidents, and enhances the safety and stability of the train. The train has the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of train braking, in particular to a train braking mitigation system and a train. Background technique [0002] With the continuous development of our country in the field of bullet trains and high-speed rail, more and more people are riding and opening trains, because people are pursuing more convenient, faster, more comfortable and safer travel methods. Therefore, how to ensure On the basis of the safety performance of high-speed rail and bullet trains, improving convenience and comfort as much as possible is the direction of continuous research by those skilled in the art. [0003] When we take the high-speed rail or the power supply of the train is abnormal due to a fault, the train will first increase the pressure of the brake cylinder due to the decrease in the pressure of the brake pipe. The braking force will stop quickly to prevent the train from running out of control and causing more serious cons...

But in this way, because the faulty train stops abnormally on the track, it is likely to affect the running of other trains. This situation is also quite dangerous, so the faulty train needs to be pulled to a safe area

[0004] However, due to the abnormal power supply of the faulty train, the wheels of each carriage are in a braking state, and the electronic brake release device commonly installed on the train cann
