Abstract

A brake friction disc attrition degree detection system based on the elastic wave and the wireless network belongs to the test engineering technology field. The invention comprises a movable wireless network terminal, an elastic wave stimulating module, an elastic wave signal receiving and transmitting module, and a vehicle computing and decision module, the movable wireless network terminal transmits a detection instruction to the elastic wave stimulating module, the elastic wave stimulating module generates a stimulating wave, an elastic wave is generated in the friction disc and transmitted to the elastic wave signal receiving and transmitting module, the elastic wave signal receiving and transmitting module digitizes the elastic wave signal and transmits the elastic wave signal to the vehicle computing and decision module, and the vehicle computing and decision module acquires the arrival time and the practical transmitting speed of the elastic wave signal, to acquire the attrition degree of the friction disc with the comparison with the database in the vehicle computing and decision module and to transmit the attrition degree to the mobile wireless network terminal. The invention detects the attrition degree of the brake friction disc and transmits the attrition degree to the driver at proper time, to enhance the security of the vehicle running.

Description

technical field [0001] The invention relates to a system in the technical field of testing engineering, in particular to a brake friction plate wear degree monitoring system based on elastic waves and wireless networks. Background technique [0002] The method of periodic detection and maintenance of automobile brakes has obtained the most extensive application at present. When the car runs for a certain period or runs to a certain mileage, it is necessary to carry out inspection and maintenance of car performance and key components to ensure the safety of the car. The main disadvantage of this method is that the driver is usually not aware of the performance and health of these components outside of the regular maintenance inspection time. Brake pads are one of the most critical components for the safe driving of a car. If the degree of wear cannot be known in time, immeasurable losses may be caused. At present, there are two methods for detecting the wear degree of brake...
