Design of Detecting System for Anti-skid Valve of High Speed Locomotive
Based on the high-speed data acquisition technology,the PWM control technology and the sealing detec tion method of differential pressure,an anti-skid valve detecting system is designed.The detecting system can detect the action response time,the stage charging and exhausting air performance and the sealing performance of the antiskid valve.Under the condition of the simulation of the actual braking condition,the system controls the solenoid valve on-off by outputting the PWM with fast response performance.It realizes a high accuracy detection of the performance of the anti-skid valve.The repetitive experiments are performed on detecting system.The test data show that the maximum uncertainty of the stage charging and exhausting air performance is 0.834 kPa,and the sealing test is 0.011 kPa.
