On-off automatic detection device for loops of collector ring

Abstract

The invention discloses an on-off automatic detection device for loops of a collector ring and belongs to the field of electric performance testing of an electromechanical device. The device is respectively connected with a loop lead and an electric brush lead of the detected collector ring through two complex programmable logic devices CPLD to establish a plurality of measuring loops and is used for realizing a man-machine operation interface by operating and controlling a computer; a used singlechip is used for realizing locking and gating of each measuring loop by an address latch and two decoders; and the singlechip is used for sequentially sending high-level data to an output pin at an initial end, i.e. the CPLD 1, of each measuring loop by built-in software and reading the level data transmitted back through the collector ring on all input pins at a tail end, i.e. the CPLD 2, of each measuring loop each time when sending one piece of high-level data so as to judge the state of the loops of the collector ring, i.e. switching-on or switching-off or shirt circuit. The device solves the problem of automatically detecting the on-off states of a plurality of loops of the collector ring. The on-off automatic detection device for the loops of the collector ring has high detection efficiency, is convenient to operate, is visual to display and has higher superiority for the collector ring with a large number of the loops.

Description

technical field [0001] The invention belongs to the field of electrical performance measurement of electromechanical devices, and relates to a detection device for detecting the on-off state of a circuit in an electro-mechanical device, in particular to a device capable of automatically detecting the on-off state of a confluence ring. Background technique [0002] The slip ring is an electromechanical device that transmits power and information between mechanisms with relative rotational motion. Its characteristic is that there can be multiple current channels on one circumference, and there will be no cable twisting due to the 360° rotation of the rotor fixed with it. Slip rings have been widely used now, especially in weapon systems such as airborne photoelectric stabilization, artillery control systems, and rotating radar antennas. According to different product requirements, the number of wires installed in the bus ring is also different. The bus ring used for airborne ...

AI Technical Summary

Problems solved by technology

This test method is complicated to operate and inconvenient to record, especially for the confluence ring with a large number of loops, it will increase the fatigue of the testers and cause test errors

The current bus ring automatic detection device is only used to detect the contact resistance, insulation resistance, dielectric strength and phase characteristics of the bus ring loop. It does not test the loop continuity of the bus ring, and cannot intuitively see whether the loop exists. Problems with short circuit or open circuit
