Problems solved by technology

[0003] At present, there are mainly the following problems in the fault detection of the electronic control system of engineering vehicles: First, the cable of the actual vehicle electronic control system is connected to the power cabin, cockpit and passenger cabin, and the length is long, so it is very inconvenient to measure the vehicle status. However, the cables are often fixed in the car body, which is extremely inconvenient to disassemble and easily cause secondary damage; second, the cable detection mainly uses simple on-off equipment such as a multimeter for detection, and this process is cumbersome and the workload is heavy. Large, it takes a lot of detection time, which brings a lot of inconvenience to the actual operation; third, the cable is only a signal connection device, and the cause of the fault may be related to the sensor or controller. Only the detection of the cable often cannot find the cause of the fault, resulting in a waste of working time. It is necessary to re-check the cause of the fault

Abstract

The invention relates to a fault detection system for an electronic system of an engineering vehicle and a detection method for an electronic system of an engineering vehicle. The fault detection system comprises a cable detection unit and a control cable detection unit. The cable detection unit comprises an analog sensor signal module, wherein an input terminal of the analog sensor signal module is connected with a switch, a power supply is used for supplying power to the analog sensor signal module, and a power supply input terminal is connected with a charging interface and an electric quantity indicator lamp. An output terminal of the analog sensor signal module is connected with a wall penetrating joint or five joint modules. When the output terminal of the analog sensor signal module is connected with the wall penetrating joint, the analog sensor signal module is connected with a sensor signal cable in a driving cab through the wall penetrating joint of a vehicle. When the output terminal of the analog sensor signal module is connected with the five joint modules, analogy vehicle sensor signals are transported to a vehicle-mounted computer by sensor cables in a power cabin, the wall penetrating joint of the vehicle and the sensor signal cables in the driving cab to display sensor cable faults in the power cabin. The fault detection system and the fault detection method disclosed by the invention can be widely applied in the cable fault detection of electronic control systems of engineering vehicles and engineering machinery transmission.

Description

technical field [0001] The invention relates to a detection device and a detection method, in particular to a portable engineering vehicle electric control system fault detection device and a detection method. Background technique [0002] In recent years, the informatization level of engineering vehicle gearboxes has increased year by year, and the shift control of gearboxes has gradually changed from purely mechanical to circuit control. In the electronic control system of gearboxes, cables are an important part. When there is a problem with the electronic control system How to quickly detect the fault location and fault type is an important part of the actual vehicle maintenance guarantee. [0003] At present, there are mainly the following problems in the fault detection of the electronic control system of engineering vehicles: First, the cable of the actual vehicle electronic control system is connected to the power cabin, cockpit and passenger cabin, and the length is ...
