Problems solved by technology

[0003] However, at present, train braking faults such as unexpected emergency braking, natural braking and holding brakes often occur during train operation.
At present, the existing technology still stays in the manual inspection stage for the inspection of brake failure, and has not yet realized real-time monitoring.
For long trains, relying on manual confirmation of braking performance is prone to missed inspections, which will affect driving safety in severe cases
At the same time, train inspection operators work in the open air all year round, with high labor intensity and low labor efficiency, which greatly restricts the improvement of Daqin Railway transportation efficiency

Abstract

The invention provides a railway wagon air brake fault judging method and belongs to the technical field of train brake system fault judging. According to the railway wagon air brake fault judging method, the type of a train brake fault is judged according to a brake cylinder upstream air pressure, a brake cylinder downstream air pressure, a train pipe air pressure, a sub air cylinder air pressureand a changing speed of each pressure. According to the railway wagon air brake fault judging method, the type of a train brake system fault can be accurately judged, manual checking of a brake faultcan be reduced, the missing rate is greatly reduced, and the running safety is further enhanced; and meanwhile, the labor intensity of train overhauling personnel is reduced, the overhauling efficiency is enhanced, and the train transporting efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of train brake control, in particular to a method for judging air brake faults of railway wagons that can accurately judge the types of brake faults of trains. Background technique [0002] The Daqin Railway is an extremely important heavy-haul railway in my country. As early as April 2014, a 30,000-ton heavy-duty train test operation was realized, with a marshalling length of nearly 4 kilometers. In order to ensure the driving safety of trucks on the Daqin Railway, a ground-to-vehicle safety warning system (5T system) has been built along the Daqin Railway, which has realized the dynamic detection of the running safety of trucks by ground equipment and significantly improved the safety prevention capabilities of railway transportation. [0003] But at present, train braking failures such as train accidental emergency braking, natural braking and holding brake often occur in train operation. And present pri...
