Problems solved by technology

The traditional detection method is to use manual measurement method. The tester uses a multimeter to conduct a continuity test, mark the two ends of the cable conduction respectively, and then carry out the crimping of the aviation plug / terminal at both ends of the cable. For electrical equipment, the accuracy of detection is often affected by factors such as the familiarity of the inspectors with the technical drawings of cable wiring definitions, the number of detection cables, and long-term testing that may easily lead to physical and mental exhaustion. It is prone to the risk of wrong wiring, which is time-consuming and laborious. Test efficiency is very low

Abstract

The invention provides an automatic cable wiring detection system. A relay switch matrix is connected with one end of a tested cable; an AD acquisition circuit is used for acquiring the on resistanceof a loop where the tested cable core is located in real time; a connection point at the other end of the tested cable core is automatically searched according to whether the on resistance is the sameas the resistance of the standard resistor, and automatic detection and matching of cable wiring are realized, so that the working intensity of detection personnel is reduced, wiring errors caused bymanual detection of the detection personnel are effectively avoided, and the wiring detection accuracy and the detection efficiency are improved; and the system is a wiring detection system which canavoid production faults, reduce the production cost and improve labor efficiency.

Description

technical field [0001] The invention belongs to the technical field of electrical testing, in particular to an automatic detection system for cable wiring. Background technique [0002] Cables are an important part of connecting and maintaining the normal operation of equipment and equipment. In the manufacturing, production, maintenance of military industries such as aviation, aerospace, weapons, and ships, as well as the production, operation, and maintenance of electrical equipment in civil fields such as transportation, electric power, and communications, Cable wiring needs to be tested. [0003] The connection cable of the equipment equipment is usually composed of a cable and an aviation plug / terminal, and the cable aviation plug / terminal is adapted and mated with the input and output interface aviation plug / terminal of the connected device. To ensure correct wiring of cables, wiring inspection is required. The traditional detection method is to use manual measuremen...
