Description

technical field [0001] The invention relates to aviation cable inspection equipment, in particular to an intelligent detection system for the conduction and insulation of aviation wire harnesses. Background technique [0002] The complex and diverse cable network systems in large-scale system engineering such as aviation and aerospace provide power supply and signal transmission paths for the interconnection of hardware devices. In order to ensure the safety and reliability of power supply and signals, the entire aviation cable network needs to be checked before use. [0003] Traditional aeronautical conduction and insulation testing uses manual single-point-to-single-point and single-point-to-multipoint insulation inspections from each contact on each connector to all other contacts one by one. The detection method is complicated and takes a long time to detect. Moreover, the safety and reliability of traditional detection methods are poor, the coverage is not comprehensive...

AI Technical Summary

Problems solved by technology

[0003] Traditional aeronautical conduction and insulation inspections use manual one-by-one inspections of each contact on each connector to all the rest of the contacts to conduct single-point to single-point, single-point to multi-point insulation inspections. The detection method is complex and takes a long time to detect.

Moreover, the safety and reliability of traditional detection methods are poor, the coverage is not comprehensive, and the utilization rate of manpower, material resources, time and resources is low
