Abstract

The invention discloses an automobile vibration fault detection system and a detection data analysis method thereof. The automobile vibration fault detection system comprises a vibration signal acquisition device and a vibration signal processing device. The vibration signal acquisition device is arranged on an automobile. The vibration signal acquisition device comprises at least one acceleration sensor which is connected with the vibration signal input end of a controller. The wireless transmitting end of the controller is connected with a wireless transmitter. The vibration signal processing device comprises a wireless transmission device which is used for receiving the vibration signal transmitted by the wireless transmitter. The wireless transmission device is connected with a processor. The processor is also connected with a data analyzer and a data storage device. The data analyzer is used for performing data analysis on the vibration signal. The data storage device is used for storing the vibration signal. The beneficial effects are that the automobile operation safety factor is great, the vibration signal detection accuracy is high, the vibration signal processing speed is fast and the maintenance speed is fast.

Description

technical field [0001] The invention relates to the technical field of automobile vibration fault detection, in particular to an automobile vibration fault detection system and a detection data analysis method. Background technique [0002] With the development of science and technology, the development of detection instruments has been greatly promoted, and the development of small portable detection instruments with compact mechanism, superior performance, low price and easy operation is particularly rapid. [0003] In the automotive field, when a car breaks down, the vibration signal often changes during the running of the car. In the prior art, it is often found that the car failure is only found when there is a defect in the car response during the driving operation, and the car failure cannot be reported in advance, and the safety factor is low during the driving process of the car. [0004] Currently on the market, vibration detection also has the following defects: ...
