Hand brake valve on-line performance detection test bed control system and application method thereof

Abstract

The invention discloses a hand brake valve on-line performance detection test bed control system which comprises an industrial personal computer PC, a data collection card AI module, an air pressure sensor, a data collection card DO module, a magnetic valve, an electrical proportional valve, a motion control card and a servo motor. The industrial PC is simultaneously connected with the data collection card AI module, the data collection card DO module and the motion control card, the data collection card AI module is connected with the air pressure sensor, the data collection card DO module is connected with the magnetic valve, and the magnetic valve is connected with an electrical control valve; the motion control card is connected with the servo motor, and the servo motor is used for controlling a handle of a hand valve; the air pressure sensor is arranged at an air outlet of the hand valve, and the electrical proportional valve is arranged at an air inlet of the hand valve. The hand brake valve on-line performance detection test bed control system can automatically carry out quick and stable testing on the sealing performance of the hand brake valve, interference of human factors in the process of testing is eliminated, and accuracy is improved greatly; meanwhile, the system improves data accuracy.

Description

Technical field [0001] The invention relates to the field of performance detection of automobile parts, in particular to a control system of a hand brake valve online performance detection test bench and a use method thereof. Background technique [0002] The hand brake valve is an important device in the automobile air brake system. The hand brake valve is an important mechanism for the car to stop and stop the car in place. As an indispensable part of automobile air brake system, hand brake valve is very important for its performance test. Traditional hand brake valve testing equipment mostly adopts 0.4-level combined instrument display and semi-automatic operation. Factors have a greater impact. [0003] Summary of the invention [0004] The purpose of the present invention is to overcome the shortcoming that the hand brake valve test equipment in the prior art has a greater influence of human factors, resulting in insufficient accuracy of its performance test, and to provide a...
