AI Technical Summary

Technical Problem

Existing automated testing systems typically only test one device at a time when testing airborne avionics, resulting in low testing efficiency and an inability to complete the testing of multiple devices within a limited time.

Method used

The airborne avionics parallel automatic test system is adopted to realize the parallel testing of multiple test objects through test control unit, interface adapter unit and test object unit. The identification resistor is used to identify professional information and model information, and the signal matching model is combined to match signal requirements with resource capabilities.

Benefits of technology

It significantly improved testing efficiency, shortened testing time, increased testing throughput per unit time, and improved the utilization rate of testing equipment.
