Parameter monitoring system and method for rotating part

Abstract

The invention provides a parameter monitoring system and method for a rotating part. The system comprises a rotor assembly and a stator assembly. The rotor assembly is connected with a sensor arranged on a to-be-tested rotating part, and the rotor assembly and the to-be-tested rotating part rotate synchronously; the rotor assembly is also connected with the stator assembly; the rotor assembly is used for receiving detection signals sensed by the sensors, performing signal processing on the detection signals to obtain a first processing result, and sending the first processing result to the stator assembly through space optical communication; and the stator assembly is used for encoding the first processing result to obtain a second processing result, and sending the second processing result to the monitoring equipment, so that the monitoring equipment monitors parameters of the to-be-tested rotating part. Real-time online monitoring of parameters such as temperature and strain of the to-be-tested rotating part is achieved, transmission is achieved through space optical communication, interference is not likely to happen, the accuracy of parameter detection results is effectively improved, and the problem that in the prior art, wireless radio frequency is likely to be interfered is solved.

Description

technical field [0001] The invention relates to the technical field of parameter detection, in particular to a system and method for parameter monitoring of rotating components. Background technique [0002] Rotating components such as blades, disks, shafts, bearings, and rotating gears of engines and gas turbines work in harsh environments with high temperature, high rotation, and high vibration. The important data of the state is also a necessary measurement index for the design research and test verification of the rotating parts. The effectiveness, real-time and stability of the data acquisition and transmission of the parameters are related to the control, monitoring, operation, safety and maintenance of the entire life cycle of the equipment. To realize real-time monitoring and fault diagnosis of rotating parts, it is necessary to use a reliable sensing parameter detection system that does not hinder the normal operation of rotating parts to monitor the operating statu...
