Multi-channel independent judgment and vibration monitoring system with redundant settings

Abstract

The disclosure provides a vibration monitoring system with multi-channel independent judgment and redundant setting, mainly including: a signal input module, coupled to multiple vibration sensors, used to receive and process the first vibration signal input by multiple vibration sensors, through N road signal output channels output n road second vibration signals; the multi-channel independent early warning judgment indication module, the multi-channel independent alarm judgment indication module, and the multi-channel maximum value judgment indication module connected in parallel to the n road signal output channels are respectively used for Judging and indicating the second vibration signal exceeding the preset warning value and preset alarm value and its corresponding signal output channel, judging and indicating the signal output channel with the largest signal amplitude among the n signal output channels and its signal amplitude. The multi-channel vibration monitoring device provided by the present disclosure can use multiple independent channels to monitor vibration signals in parallel.

Description

technical field [0001] The present disclosure relates to the technical field of electronic power, in particular, to a vibration monitoring system with multi-channel independent judgment and redundant setting. Background technique [0002] Mechanical equipment running at high speed requires vibration monitoring. Aeroengines and gas turbines are high-temperature, high-speed power equipment, and vibration monitoring is particularly important during scientific research and testing. [0003] Existing vibration monitoring instruments include pure hardware circuit instruments and monitoring instruments using a single-chip microprocessor. The pure hardware circuit instrument is realized by circuits such as comparators, analog switches, and standard signal settings. It only has general early warning and alarm functions. Realize redundant monitoring and control; the monitoring instrument using a single-chip microprocessor is realized through the combination of hardware and software, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of this disclosure is to provide a vibration monitoring system with multi-channel independent judgment and redundant settings, which is used for vibration monitoring of aero-engine tests or other high-speed mechanical equipment vibration monitoring, so as to solve the problem of existing vibration monitoring equipment with single function or no Independent operation of multi-channel hardware, redundant monitoring combination setting and judgment strategy setting functions, etc., resulting in problems such as low reliability and limited adaptability
