Embodiment Construction

[0044] In order to further illustrate the technical means adopted by the present invention and its beneficial effects, a further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention.

[0045] Such as figure 1 Shown is the flowchart of the analysis method of the present invention, and the method may further comprise the steps:

[0046]Step 1: Obtain the fault codes and data streams of the car computer, and transmit the acquired fault codes and data streams to the cloud server through the smart terminal;

[0047] Step 2: the cloud server judges whether there is a fault code;

[0048] Step 3: if there is no fault code, the data flow obtained is stored as a normal data flow;

[0049] Step 4: if there is a fault code, the data flow obtained is stored as an abnormal data flow;

[0050] Step 5: set up abnormal number flow sample and normal data flow sample at cloud server, and calculate and analyze data flow...

Abstract

A cloud computing based analysis method of an automobile abnormal data stream comprises that a fault code, if there is, and the data stream of an auto computer are obtained and sent to a cloud servervia an intelligent terminal; the cloud server determines whether there is the fault code, and if no, the obtained data stream is stored as a normal data stream; if there is the fault code, the obtained data stream is stored as an abnormal data stream; an abnormal data stream sample and a normal data stream sample are established in the cloud server, and the data stream samples are calculated and analyzed; data items related to the fault code are found in the abnormal data sample; a fault-free data stream which needs testing is obtained, and compared with the abnormal data stream sample and thenormal data stream sample to obtain related critical data; the abnormal and normal data stream samples are added and perfected; and the possibility that the abnormal data stream related to the faultcode or automobile fault corresponds to the data item is counted in the abnormal data stream sample. Hidden troubles of the automobile are determined so that the automobile can run healthily.

Description

technical field [0001] The invention belongs to the technical field of automobile diagnosis, and in particular relates to an analysis method for abnormal data flow of automobiles based on cloud computing. Background technique [0002] In the field of automobile diagnosis technology, the car computer ECU self-diagnosis system will monitor the data of the car running status, and allow the car running status data to be read through the diagnostic interface DLC of the car computer ECU. Its data flow will change accordingly, collectively referred to as abnormal data. [0003] At present, the data flow analysis of automobile self-diagnosis system has become the most commonly used method for automobile fault diagnosis. However, at present, the diagnosis and analysis of the data flow mainly depends on the manual analysis and judgment of the maintenance technician with the help of the maintenance manual. It is impossible for the car owner to know the meaning of the data flow and the...
