Conductive slip ring online parallel test system and test method

Abstract

The invention relates to a conductive slip ring online parallel test system . The online parallel test system comprises a work switching module, a high-speed clock frequency multiplication module, a test signal generation module, a test signal feedback module, a test diagnosis module and a test information communication module; the work switching module controls initialization of the high-speed clock frequency multiplication module; clock signals output by the high-speed clock frequency multiplication module are used as clock references of the test signal generation module and the test diagnosis module; the test signal generation module generates a test signal input into conductive slip rings, the test signal feedback module receives the test signal output by the conductive slip rings, thetest diagnosis module records communication test fault information, and the test information communication module transmits diagnosis information. The conductive slip ring online parallel test systemis suitable for the online parallel test of the conductive slip rings, achieves the performance test of the plurality of conductive slip rings, improves the test efficiency of the conductive slip rings, and can improve the fault diagnosis accuracy and accuracy of the conductive slip rings.

Description

Technical field [0001] The invention belongs to the technical field of conductive slip ring testing for ship navigation systems, in particular to a conductive slip ring online parallel testing system and testing method. Background technique [0002] Inertial systems are widely used in sea, land, air, space, police and many other fields. With the continuous development of inertial technology, the accuracy of inertial systems is constantly improving. The rotating mechanism is an important part of the platform type, rotating modulation type and hybrid inertial system, and the conductive slip ring is also widely used in the inertial system along with the rotating mechanism. [0003] The conductive slip ring is mainly composed of brushes, slip rings, miniature bearings and some related structural parts. It is suitable for 360°unrestricted free rotation to ensure that the electrical signal between the fixed mechanism and the rotating mechanism of the equipment can be uninterrupted trans...

AI Technical Summary

Problems solved by technology

[0004] However, the working principle of the inertial system determines that the conductive slip ring has been in a state of wear for a long time since it was installed. When the conductive slip ring fails due to excessive wear, the signal path will be disconnected, and the inertial system will fail.
