Abstract

The invention provides a fault diagnosis system. The fault diagnosis system includes an execution terminal, a controller, a fault diagnosis module, a first output terminal and a background server; the execution terminal is arranged in a vehicle and is connected with the controller, and monitors the operation signals of various components in the vehicle; the controller is connected with the fault diagnosis module, monitors the fault diagnosis module, and transmits monitored first monitoring signals and received operation signals to the fault diagnosis module; the fault diagnosis module monitors the controller, receives the first monitoring signals and the operation signals, and performs diagnosis; and the background server receives abnormal signals and judges the fault condition of the vehicle. Thus, the controller and the fault diagnosis module in the fault diagnosis system can monitor each other and give feedback to each other, so that errors in detection results caused by the damage of the controller or the fault diagnosis module can be avoided.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a fault diagnosis system. Background technique [0002] With the rapid development of my country's automobile industry, the number of automobiles, especially storage vehicles, is increasing day by day. The number of car maintenance and fault diagnosis is also increasing. At present, the users of storage vehicles are generally non-professionals, and they have little understanding of storage vehicles. Once a vehicle fails, it is impossible to judge the fault and follow up. Simple maintenance requires professional After-sales service personnel handle it, which will cause inconvenience for customers to use, and it will take a certain amount of time for after-sales personnel to diagnose and repair the fault, which will delay the construction period. [0003] At present, a fault diagnosis system is generally installed in the vehicle to solve the problem of fault diagnosis. Ho...
