Abstract

The invention relates to a labview-based aeroengine ground stand test monitoring system, used for monitoring states in an aeroengine stand test, and comprises setting control parameters, sending control instructions, receiving and displaying state parameters in real time, and storing and analyzing experiment data. The system comprises a data collector and a computer with a labview exploitation platform. The system utilizes a serial port communication method to avoid data loss in high speed collection and data transmission processes, reliably controls an engine, and can store and analyze experiment data. The system can be used for state monitoring and performance analysis in an aeroengine preresearch phase ground green test process, and is an aeroengine ground green test monitoring system with complete functions.

Description

technical field [0001] The invention designs a host computer monitoring system, in particular to a labview-based aero-engine ground bench test state monitoring system, which is used for state monitoring and control during the aero-engine bench test. Background technique [0002] Testing is a basic method for people to understand the objective world through experiments to obtain qualitative or quantitative information about the subjects. In the development process of contemporary science and technology, testing work is the guarantee of the performance and quality of modern equipment systems. With the continuous improvement of the performance of aero-engines, more and more parameters are obtained in the engine bench test, and the requirements for the accuracy and speed of measurement and control are also getting higher and higher. The traditional method of manually recording test data can no longer meet the needs of modern aero-engines. Experimental requirements. Contents o...
