The invention discloses an automobile fault positioning system, and the system comprises a single-chip microcomputer. The output end of the single-chip microcomputer is connected with an alarm unit and the input end of the single-chip microcomputer is connected with a data processing unit. The input end of the data processing unit is connected with the data collection unit, and the data processingunit comprises a signal conversion module, a signal extending module and a signal screening module. The signal conversion module, the signal extending module and the signal screening module are connected through signal lines. According to the invention, the vibration sensor is directly installed on a vehicle body, and is connected with a vehicle-mounted computer, thereby solving the problems thata conventional automobile fault positioning method cannot accurately judge the position of an abnormal sound source, cannot locate and eliminate the fault, and consumes a lot of time and labor.
Description
technical field [0001] The invention relates to the technical field of automobile detection, in particular to an automobile fault location system. Background technique [0002] With the development of the times, cars have become an indispensable means of transportation for people, and more and more people use cars as their first means of travel. However, car failures are inevitable, which not only greatly reduces the fun of driving and riding, More importantly, it will cause great hidden dangers to the safety of oneself and others. Once a traffic accident occurs, it will cause an irreparable situation. [0003] In the prior art, the method of locating a car fault is to let the car making the abnormal sound drive on a rough road section, find the approximate location of the abnormal sound, and then further investigate the source of the abnormal sound, so as to determine the source of the fault and troubleshoot the problem. repair. This method cannot accurately determine the...
