Vehicle fault online detection and early warning device based on internet of vehicles and vehicle fault online detection and early warning method thereof

Abstract

The invention provides a vehicle fault online detection and early warning device based on the internet of vehicles and a vehicle fault online detection and early warning method thereof. The device comprises a vehicle-mounted terminal, a remote server side, a vehicle owner mobile phone client side, a maintainer client side and a maintenance manufacturer client side. According to the detection method, the vehicle-mounted terminal acquires vehicle information, wherein the vehicle information includes the data of an OBD interface and the data acquired by a sensor so as to realize vehicle online real-time monitoring; the vehicle information is transmitted to the remote server side to perform big data intelligent analysis so that the existing problems of the vehicle are obtained and early warning is provided and faults can be avoided; besides, a vehicle maintenance scheme can be intelligently provided, and the data are fed back to the vehicle owner and the maintenance shop of the maintainer through the vehicle owner mobile phone client side, the maintainer client side and the maintenance manufacturer client side so that the vehicle owner can understand the situation of the vehicle in real time and take measures for fault prevention, the maintainer can view the data and the analysis result of the remote server side and thus maintenance is facilitated.
