Principles of Electronic Harness Fault Detection

For different electronic parts, the harness contains the number of wires and the number of colors are different, the number of wires can be from a few, dozens of roots to hundreds of roots, the color can be from a few, a dozen to dozens of species (including monochrome and bi-color), terminal wire harness fault detector (hereinafter referred to as the detector) once detected an open or short-circuit fault, it should be able to immediately display the type of fault, the fault wire color and location, so that the operator instantly Discovery and troubleshooting. In order to achieve the above functions, the following detection method: first of all the endpoints of the harness number, and the endpoint number by color grouping, and then by grouping the color and the endpoint number into the detector (a type of harness only need to enter once). Detector of the specific detection process is divided into short-circuit fault detection and open-circuit fault detection of two steps: set up a certain type of wiring harness A (red), B (blue), C (green) three groups of endpoints, the endpoints within the group is connected to the endpoints of the group, the group of endpoints and all the endpoints outside the group are not connected. Short-circuit fault detection: first detect any end point in group A and B, C group of endpoints between whether the conductor, if they are not pass, that the end point and B, C group of endpoints between the short-circuit fault; such as with a certain endpoints between the conductor, the detector will immediately display the type of fault, the fault wire color and endpoint number. Sequentially detect the other endpoints in group A and group B, C between the endpoints whether the conductivity can be realized short-circuit fault detection. Open-circuit fault detection: using a single cycle to detect whether the endpoints in the group is disconnected between the open-circuit fault detection can be realized.
