[0002] The A320 aircraft system health test refers to the regular testing of aircraft system-related circuits and components to ensure that the conductivity and insulation of the overall circuits and components meet the expected standards. Generally, the conductivity and insulation of the overall electrical loop of different components and related circuits of the aircraft system are measured at the aircraft computer socket. However, there is currently no dedicated measurement equipment in China for the components and circuits of the overall aircraft system. In actual work, workers usually use a multimeter to complete related testing work. The aircraft system health inspection work requires the inspection of multiple circuits and components of the system, and requires the participation of multiple people in the measurement work, including completing the actual measurement work, reading circuit drawings, providing lighting and construction tools, etc. The measurement workload is large, and it takes a long time to complete this work using a multimeter. In addition, the multimeter pen does not match the measurement jack, and cannot maintain sufficient and stable contact during measurement, resulting in poor contact, which directly affects the measurement accuracy. At the same time, there are many jacks inside the aircraft computer socket, and it is difficult to accurately find the two jacks that need to be measured. The space in the socket area at the rear of the aircraft computer is small, and the relevant measurement points are difficult to approach. In addition, the space in the socket area at the rear of the computer is deep, and the ambient light in the area is insufficient, which will affect the worker's line of sight during measurement, causing the worker to not be able to see the corresponding measurement jacks clearly, and measurement errors are prone to occur.
[0003] Therefore, affected by the above-mentioned multiple unfavorable factors, the measurement data of aircraft fault detection by the existing technology is not accurate, the error rate is high, the measurement work is time-consuming and labor-intensive, and it is very easy to cause the quality of regular aircraft inspections to be low, the troubleshooting work to be time-consuming and labor-intensive, and thus lead to flight delays.
