Abstract

The invention discloses a method for detecting the pressure abnormity of an electric locomotive brake cylinder. The method involves a brake cylinder pressure sensor on a brake cylinder pipeline and atrain pipe pressure sensor on a train pipeline. The brake cylinder pressure sensor is used for collecting pressure signals in all brake cylinder pipelines. The train pipe pressure sensor is used for collecting pressure signals of train pipelines. The signal processing module collects train pipe pressure signals and brake cylinder pressure signals, collects brake controller position signals transmitted in a locomotive network and calculates and analyzes the train pipe pressure signals and the brake cylinder pressure signals to judge whether the pressure of a brake cylinder is abnormal or not. Thus, the real-time monitoring of the pressure abnormity of the brake cylinder of the locomotive as the attached and tracked vehicle is realized.

Description

technical field [0001] This patent only relates to the field of railway electric locomotives, in particular to a method for detecting abnormal pressure of brake cylinders of electric locomotives. Background technique [0002] The electric locomotive brake cylinder is the basic braking unit of the electric locomotive braking system and the key executive component of the air braking system, which plays a decisive role in the realization of safe and reliable air braking of the electric locomotive. At this stage, when the brake system or related components fail, the actual pressure value of the brake cylinder at each axis will be inconsistent with the theoretical output value required by the brake system, which is extremely harmful to driving safety. If the actual situation of the brake cylinder of the electric locomotive can be known in time and corresponding measures can be taken, the influence of the failure can be minimized and the driving safety can be guaranteed.
