ABSTRACT

The single-chip microcomputer generates a 4-channel square wave input to the ABS-driven solenoid valve, it drives the continuous operation of the ABS system, which lays a foundation for the ABS system fault diagnosis research. It established a data acquisition system that collected vibration signals, sound signals, and pressure signals, and these signals can correspond to the opening process of the solenoid valve in time, and analyze and process, monitor and extract the characteristic parameters of the dynamic signal. This can reflect the mechanical movement of the solenoid valve and enable the detection of the failure of the ABS system.
