Abstract

The invention belongs to the technical field of fault detection equipment, and discloses a detection device, which comprises a plug assembly, a driving assembly, a connecting assembly and a detection unit, and is characterized in that the plug assembly comprises a plug, the plug is provided with a plurality of connecting paths which are arranged in parallel and are different from one another, and the plug is used for being electrically connected with a detected electric device; the driving assembly can drive the connecting assembly to be plugged with the plug, so that one of the plurality of connecting paths of the plug is communicated, the detection unit is electrically connected with the plug, and the detection unit is used for detecting electric power parameters of the detected electric device under different connecting paths. The detection device can detect each electric power parameter of the detected electric device in an omnibearing manner, so that risk items of the detected electric device are evaluated in an omnibearing manner according to each electric power parameter, and meanwhile, the problems of tedious operation steps, error detection or relatively large measurement errors caused by manual testing are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of fault detection equipment, in particular to a detection device. Background technique [0002] When assembling the engine, the wiring harness at the end of the ECU to the vehicle is generally a non-standard type. The main engine factory designs the wiring harness according to the electrical matching manual provided by the engine manufacturer and its own needs. Due to design errors or wiring errors, the ECU may have adverse effects and malfunction. [0003] Existing ECU wiring harness detection technology is mainly divided into functional confirmation and targeted detection after failure. The function confirmation is generally after the engine is assembled into the whole vehicle, the test run of the main engine factory and the ECU function confirmation by the engineer of the engine factory are tested. The targeted detection after the failure is to use traditional testing equipment (multimeter, oscilloscop...
