Abstract

The application provides an intelligent monitoring device and system for a wind tunnel measurement system. Via a switching module, sensor signals can be switched to a test loop circuit of an originalwind tunnel measurement system and a measurement module of the system; while an original wind tunnel test loop circuit is prevented from damage, original sensor signals of the wind tunnel measurementsystem can be switched and measured in real time; a performance assessment result of the sensor signals, a performance assessment result of conditioned and amplified signals and a result of comparisonbetween the sensor signals and the conditioned and amplified sensor signals can be obtained; intermediate state testing and comparison testing of wind tunnel experiments can be realized; via the intelligent monitoring device disclosed in the application, gain of a signal conditioning amplifier can be obtained according to the result of comparison between the sensor signals and the conditioned andamplified sensor signals; whether gain is deviated from preset gain of the signal conditioning amplifier can be determined, and credibility and validity of wind tunnel measurement system data can beimproved.

Description

Technical field [0001] The invention belongs to the technical field of monitoring of hardware equipment or systems, and particularly relates to an intelligent monitoring device and system suitable for a wind tunnel measurement system. Background technique [0002] In fluid mechanics, wind tunnel experiment refers to an aerodynamic experiment method in which an aircraft or other object model is placed in a wind tunnel to study the gas flow and its interaction with the model to understand the aerodynamic characteristics of the actual aircraft or other object model . [0003] The wind tunnel measurement system, as one of the core systems of wind tunnel experiments, provides high-precision, multi-channel, high-gain signal testing capabilities for aerodynamic experiments. Due to the complex working conditions of the experimental site and the lack of intermediate state tests and comparative tests, it is difficult to verify the validity of the measurement data of the current wind tunnel ...
