Detection method of automobile brake block thickness real-time detecting system

Abstract

The invention discloses a detection method of an automobile brake block thickness real-time detecting system, and belongs to the field of an automobile braking system. The method comprises the steps: 1, thickness signal acquisition: a power switch S 1 of a sensor and a power switch S2 of a signal processing module are switched on, an eddy sensor and a signal processing module are powered on, a brake pedal is pressed on, a limit switch S 3 is switched off, the eddy sensor is used for detection, and thickness signals of brake blocks when the brake blocks are contacted with brake discs are obtained; 2, thickness signal data processing: a current signal obtained in the step 1 is converted into a voltage signal by a sampling resistor RL, and the voltage signal is input to the signal processing module to be processed; 3, data display and acousto-optic alarm: the real-time thickness h signals of the eight brake blocks of a left front wheel, a right front wheel, a left rear wheel and a right rear wheel of an automobile, which are obtained by processing in the step 2 are displayed by a display module. The method is simple in structure and high in measurement precision, and the safety mastering capacity of a driver is increased.
