Intelligent management system for use process of aero-engine high-altitude cabin test bed

Abstract

The invention provides an intelligent management system for the use process of an aero-engine high-altitude cabin test bed. The system comprises a sensor unit, a data collection module and a communication module; the sensor unit is connected with a data receiving module through a bus; the input end of the communication module is connected with the data collection module through a bus; the output end is connected with an aero-engine high-altitude cabin test run management main system through an optical fiber; the sensor unit transmits collected process data to the data collection module througha bus. The data collection module compares the accumulated service life of each parameter collected by the sensor with a preset service life, and carries out over-limit alarm of the service life. Bycomparing the instantaneous sampling value of each parameter acquired by the sensor with a preset threshold value, the over-limit alarm of the instantaneous sampling state is carried out. Through thereal-time monitoring of the two aspects, the early warning prompt can be provided more accurately and timely, the fatigue risk of the test bed is reduced, and the bed monitoring data support is provided for the test of the high-altitude cabin of the aero-engine.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to an intelligent management system for the use history of an aero-engine high-altitude cabin test bench. Background technique [0002] The aero-engine high-altitude cabin test bench is an essential test equipment for the high-altitude simulation test of the engine. During the high-altitude simulation test of the aero-engine, the engine is installed on the test bench, and the engine is simulated from low altitude to high altitude flight in the high-altitude cabin. The state change of the medium engine operation, which is subjected to a wide range of various load cycles during operation, especially the huge changes in all thrust, heat radiation and vibration of the aeroengine in the state of the aeroengine from idling to afterburner and full afterburner flight , The test bench is prone to fatigue, which seriously affects the safety of the engine test run. Therefore, it is necess...
