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 short circuit, open circuit, leakage or incorrect connection of electrical 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 wiring harness systems. Background technique [0002] In various electrical connections, it is necessary to make a large number of connecting wire harnesses, especially today when the functions of automobiles are becoming more and more advanced and intelligent. Vehicle electronic systems are becoming more and more complex, and the electrical control system wiring harnesses that follow are becoming more and more complex. The number is also increasing. The wiring harness is usually composed of multi-core wires, which are branched and routed according to their functions and requirements. For vehicle wiring harnesses, due to the complexity of the...
