Abstract

The invention discloses an engineering vehicle electric control system fault detection method and device, and the method comprises the steps: enabling a single-chip microcomputer to collect the vehicle data of an engineering vehicle in real time through an engineering vehicle CAN bus and a sensor, and presetting a data safety value in a program of the single-chip microcomputer; when the vehicle data collected by the single-chip microcomputer exceeds a preset data safety value or the single-chip microcomputer detects a fault code, giving an alarm prompt, so a user or WeChat personnel can roughly judge or discover an error reason only according to the fault code and make a treatment in time. Management personnel can check fault codes of numerous engineering vehicles and monitor vehicle states through the server background. According to the invention, the fault detection efficiency of the engineering vehicle can be effectively improved, the economic loss of the engineering vehicle causedby fault shutdown is reduced, and the management efficiency and the operation benefit of the engineering vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of engineering vehicle fault detection, in particular to a fault detection method and device for an electric control system of an engineering vehicle. Background technique [0002] With the development of construction vehicle technology, the electronic control system of construction vehicles is becoming more and more complex, and the maintenance cost is high when a failure occurs, and it will also cause huge loss of work delay. In the prior art, the maintenance method for engineering vehicle failures still requires maintenance personnel to survey the engineering vehicles on the spot, check the sensors of the engineering vehicles and the operating status of the corresponding devices according to the fault warning of the electronic control system to troubleshoot and perform maintenance. However, due to the large number of engineering vehicles in large-scale infrastructure projects and their distribution on dif...
