Background
the current automobile time-sharing leasing (sharing) industry develops rapidly, but the daily use and damage of the automobile are much more serious than that of a common household automobile due to the characteristic of the shared automobile (shared assets or enterprise assets). The method not only causes great trouble to the maintenance of the automobile, but also brings great potential safety hazard to subsequent vehicle users under the condition of untimely maintenance.
maintenance of shared vehicles is currently generally performed only when the following situations arise: 1. detecting and maintaining the vehicle regularly; 2. gross macroscopic trauma to the vehicle; 3. the user reports the vehicle problem. However, the above situation only exposes a small part of the problems, and some problems which are at a high risk but not easily found by visual inspection are often left. Because the operation and maintenance personnel cannot know the real-time vehicle condition details of each vehicle every day, timely maintenance and repair of each vehicle every day cannot be achieved. It becomes extremely important to employ more effective monitoring means to determine whether the vehicle is in an abnormal state and to perform timely maintenance.

utility model purpose: the utility model discloses make the improvement to the problem that above-mentioned prior art exists, promptly the utility model discloses a sharing vehicle maintenance system based on signal processing. The utility model discloses an abnormal signal sampling sensor who installs on the automobile body of sharing car acquires the abnormal state of vehicle (for example the abnormal sound of transmission shaft, the friction abnormal sound that wheel hub deformation caused, the abnormal sound of loudspeaker etc.) to thereby compare various abnormal sound audio signal and deduce the problem place and report to the suggestion fortune dimension demand of backend server on the digital signal processor for on-vehicle T-box with the sound data transmission of abnormal state.
The technical scheme is as follows: a shared vehicle maintenance system based on signal processing, comprising:
The system comprises a plurality of abnormal signal sampling sensors, a vehicle-mounted T-BOX and a shared automobile, wherein the abnormal signal sampling sensors are arranged on an automobile body of the shared automobile and are used for acquiring audio signals of the shared automobile in real time and sending the audio signals to the vehicle-mounted T-BOX in real time;
the vehicle-mounted T-BOX is respectively connected with a plurality of abnormal signal sampling sensors in a wireless communication mode and comprises:
a second wireless data module;
The input end of the digital model processor is connected with the output end of the second wireless data module;
the input end of the main control unit is connected with the output end of the digital model processor;
the storage is connected with the main control unit and used for storing problem audio data;
and the 4G communication unit is in communication interconnection with the main control unit.
further, the abnormal signal sampling sensor includes:
An audio pickup module;
and the input end of the first wireless data module is connected with the output end of the audio pick-up module.
Further, the first wireless data module is a bluetooth low energy module.
further, the abnormal signal sampling sensor is installed on the inner side of a transmission shaft or a hub of the shared automobile.
