Abstract

The invention discloses a detection system and a detection method for the shaking amount of the pointer of an aviation instrument, including detection equipment for realizing power supply to the aviation instrument and setting of the pointer state, the aviation instrument, and an instrument clamp for detecting a fixed aviation instrument Tooling and test cables also include light source, camera clamping tooling, camera cables, industrial cameras and computers. Industrial cameras are connected to computers through camera cables. Camera clamping tools are installed on instrument clamping tools. Between the cameras, the industrial camera is installed on the camera clamping tool; the industrial camera collects the image of the aviation instrument panel in real time and uploads it to the computer for analysis. The camera clamping tool realizes the fixation and focus adjustment of the industrial camera, and the camera cable realizes the power supply of the industrial camera And image transmission, the computer analyzes the image collected and uploaded by the industrial camera in real time, and calculates the amount of pointer shake.

Description

technical field [0001] The invention relates to the technical field of aviation product maintenance, in particular to a detection system and a detection method for the shaking amount of an aviation instrument pointer. Background technique [0002] In aviation equipment maintenance enterprises, there are strict regulations on the jitter of aviation instrument pointers. For example, the technical index of a certain type of emergency horizon meter requires that the jitter of the horizon should not be greater than ±0.15mm. The current detection method is mainly visual measurement, and the general detection method operation is described as follows: under good lighting conditions, the human eye observes the dial horizon vertically at a distance of 0.6m from the dial, and there should be no obvious beating. This detection method lacks quantitative standards for the determination of the test environment, human eye state, and test standards, and it is difficult to accurately determin...
