Problems solved by technology

The fault code is limited to the OBD type, and it also detects the condition of the vehicle at that time, and cannot locate the fault that occurred before the vehicle
[0005] The above solution cannot store and collect fault codes in real time for big data analysis, and after the fault codes are collected, stored and uploaded in real time, new technical problems arise, that is, after the fault classification corresponding to the fault codes is obtained, it is purely Alarm, or just display, but how to selectively alarm for the fault classification corresponding to the fault code can not only enhance the alarm efficiency, but also improve the credibility of the alarm
And no matter what kind of fault all reports to the police, often can make car owner paralyzed, the real urgently needed report to the police is ignored

Embodiment 1

[0011] Embodiment 1: In order to obtain a kind of foresight or understanding of vehicle faults in a way that occurs at any time and processed at any time, this embodiment introduces a method of monitoring vehicle conditions in real time, especially vehicle fault codes (vehicle fault codes refer to automobile failures). Afterwards, the fault codes reflected by the ECU analysis of the car computer, generally the frequent fault codes are caused by the faulty sensor work) The method of real-time diagnosis of the car by big data analysis of changes, such as figure 1 and 2 Shown: a method for real-time collection of vehicle fault codes and historical data analysis and diagnosis, characterized in that each time the vehicle is ignited, the equipment collects fault codes, and the fault codes collected by the equipment in real time on the vehicle are uploaded to the cloud by the mobile communication network platform, the cloud platform receives the fault code data, stores the fault code...

Embodiment 2

[0012] Embodiment 2: the described method for classifying faults is:

[0013] S1. Distinguish the fault category against the fault knowledge base: the fault code category needs to refer to several knowledge bases, 1. Accompanying fault code table: the table for storing associated faults. The faults stored in this table are all non-important associated fault codes. Such failures are all accompanied by other failures, or caused by the addition of other components to the vehicle, and are not decisive failures. 2. Negligible high-frequency minor faults. This type of fault occurs frequently, but the degree of damage to the vehicle is extremely slight and can be ignored. The high-frequency can be defined by setting a high-frequency threshold, and those exceeding the threshold can be high-frequency. In the same way, minor faults can also be set by setting a minor threshold, and those below the minor threshold are minor faults. Major fault table, such faults will affect the driving ...

Embodiment 3

[0018] Embodiment 3: A device for real-time collection of vehicle fault codes and historical data analysis and diagnosis, characterized in that it includes equipment, a classification module, and a reminder module, and the equipment collects fault codes every time the vehicle is ignited, and the faults collected by the equipment in real time on the vehicle The code is uploaded to the cloud platform by the mobile communication network, the cloud platform receives the fault code data, stores the fault code data in the database, and the cloud platform combines the uploaded fault data with the stored fault history data for big data analysis. Classify the faults obtained by analyzing and diagnosing fault code data, and make fault reminders based on the classification. The device is used to execute and realize the method in Embodiment 1 and / or 2.

[0019] Due to the method of fault acquisition and judgment in the prior art, it is as if a patient goes to a hospital to see a doctor an...

Abstract

The invention provides a vehicle fault code real-time acquisition and historical data analysis and diagnosis method and device and belongs to the field of fault code acquisition. The method and device solve the problem about classified warning. The method is characterized by including the steps that each time a vehicle is started, a device collects a fault code, the device collects the fault code on the vehicle in real time, the fault code is uploaded to a cloud platform by a mobile communication network, the cloud platform receives fault code data, the fault code data is stored in a database, the cloud platform combines fault data uploaded last time and stored historical fault data for big data analysis, faults obtained by analyzing and diagnosing the fault code data are classified, and fault reminding is decided according to classification. The method has the effects that warning decisions are determined according to classification, and the phenomenon that warning creditability is reduced because of all warnings can be avoided.

Description

technical field [0001] The invention belongs to the field of fault code collection and relates to a method for collecting, analyzing and diagnosing fault codes. Background technique [0002] When the vehicle has a fault, especially an electrical fault (electrical fault refers to a fault that occurs on the ECU, circuit or induction components, which is different from a mechanical fault.), the general method is to go to a 4s shop or a repair shop for repairs. Inspection can quickly discover reproducible or frequently occurring faults, but there are some occasional or hidden faults, or faults that are not easy to locate quickly, and can only be repaired after knowing that they occur. Diagnostic products are mainly: [0003] Original diagnostic instrument: This method is mainly used by 4S shops to detect faults. This method is to use the original diagnostic instrument of the car manufacturer to connect to the car through a wired connection or wireless (Bluetooth and other tech...
