Abstract

The invention discloses an aviation instrument pointer jitter amount detecting system and the detection method thereof. The system comprises a detection device for realizing the setting of power supply to an aviation instrument and the pointer state, an aviation instrument, an instrument clamping tool for detecting and fixing the aviation instrument, and a testing cable as well as a light source, a camera clamping tool, a camera cable, an industrial camera and a computer. The industrial camera is connected with the computer through the camera cable. The camera clamping tool is installed on the instrument clamping tool. The light source is arranged between the aviation instrument and the industrial camera. The industrial camera is mounted on the camera clamping tool. The industrial camera conducts real-time acquisition of the images of the aviation instrument panel, and uploads the images to the computer for analysis. The camera clamping tool achieves the fixation and the focal length adjustment of the industrial camera. The camera cable achieves the power supply of the industrial camera and the image transmission. The computer image carries out real-time analysis on the images collected and updated by the industrial camera for the calculations of the jitter amount of the pointer.

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 jitter amount of aviation instrument pointers. Background technique [0002] In aviation equipment maintenance companies, there are strict regulations on the jitter of aviation instrument pointers. For example, the technical indicators of a certain type of emergency ground level require 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 jump. This detection method lacks quantitative standards for the determination of test environment, human eye conditions, and test standards, and it is difficult to accurately determine whether...
