Method and system for judging braking state of train carriages

Abstract

The invention relates to a method for judging braking states of train carriages. The method comprises the following steps: collecting data packets which are obtained by storing brake cylinder pressure data collected by an electronic label arranged on each train carriage through a sensor, wherein the data packets comprise time marks; respectively taking out the data packets collected from the samecarriage, and acquiring a pressure variation equation of the carriage by utilizing the data packets; respectively setting a plurality of time points in the equation with the same time interval; comparing whether values acquired from each pressure variation equation on the time points are the same with each other or within the pre-set error, if so, judging that all the train carriages are in a normal braking state, or else, judging that all the train carriages are in an abnormal braking state. The invention further relates to a system for judging braking states of train carriages. The method and system for judging the braking states of the train carriages provided by the embodiment of the invention have the beneficial effect that the braking states of the train carriages can be automatically judged in real time.

Description

technical field [0001] The invention relates to a train vehicle, more specifically, to a method and system for judging the braking state of a train vehicle. Background technique [0002] With the rapid development of my country's railway high-speed passenger transport and heavy-duty trucks, the requirements for railway safety are also getting higher and higher. As the top priority of railway transportation, train driving safety is guaranteed by the stable, reliable and correct operation of the train braking system. At present, the speed of trains in our country has been increased many times, and the increased trains have put forward more stringent requirements for the stability and reliability of the braking system. If the brake system fails or has hidden dangers during driving, and cannot be discovered and dealt with in time, it will directly endanger the safety of vehicles, passengers and materials, and cause heavy losses. At present, the inspection of the brake devi...
