Abstract

The invention relates to an intelligent multi-core cable harness detection device. The device consists of a programmable power supply, an intelligent multi-channel switch, a current-limiting resistor network, a multi-core converter, a current sampling module, an analog multiplexer, a single-chip, a computer and detection software. The device can automatically analyze short-circuit performance, open-circuit performance and conduction performance of a multi-core cable harness. A harness system state is determined through a harness performance testing matrix graphical detection result and by comparing the result with a pre-stored standard, and different fault types are indicated by colors; and meanwhile, a fault alarm can be sent by an alarm device with sound and changing light. The device has the characteristics of simple and convenient operation, high testing efficiency, high system extensibility and the like, and can be directly used for development of harness-related products, quality control and performance detection.

Description

technical field [0001] The invention belongs to the technical field of testing for short circuit, open circuit, leakage or incorrect connection of electric equipment and lines. The invention relates to an intelligent multi-core cable harness detection device, in particular to a detection and performance analysis device for complex automobile harness systems. Background technique [0002] In various electrical connections, it is necessary to make a large number of connection harnesses, especially today as the functions of automobiles are becoming more advanced and intelligent, the electronic systems of vehicles are becoming more and more complex, and the wiring harnesses of the electronic control systems that follow The number is also increasing. The wiring harness is usually composed of multi-core wires, which are bifurcated and routed according to functions and requirements. For the vehicle wiring harness, due to the complexity of the control object, the main wiring harne...
