Intelligent early-warning and service system for on-board faults

The invention relates to an intelligent early-warning and service system for on-board faults, and belongs to the technical field of on-board fault diagnosis. For the purposes of the intelligent early-warning and service system for the on-board faults, the problems that individual design is required in the prior on-board diagnostic terminal hardware and the construction is complex are solved. The intelligent early-warning and service system for the on-board faults comprises the steps that the OBD diagnostic socket of the early-warning and service system is connected to a standard OBD interface; information interaction is performed between the OBD diagnostic socket and an automobile micro-controller through a bluetooth communication module; the OBD diagnostic socket acquires automobile internal data by the automobile micro-controller, and the automobile internal data is sent to a user mobile phone terminal through the bluetooth communication module; the OBD diagnostic socket further receives a command from the user mobile phone terminal through the bluetooth communication module, and requests the corresponding data from the automobile micro-controller after the command is parsed, and sends the acquired corresponding data to the user mobile phone terminal; according to the received data, an on-line fault diagnosis is performed on the automobile by the remote service center, and the diagnose results are transmitted to the user mobile phone terminal. The intelligent early-warning and service system for the on-board faults is employed to early warning and service of on-board faults.
