  ABSTRACT: This study investigates the automation upgrade of electrical performance testing for aerospace pyrotechnic devices, aiming to achieve automated testing and full-process digitalization. Through standardization of the testing, research on specialized adapters, automatic insertion technology for pins and holes, high-speed switching technique and data collection during the testing process, fully digital and automated electrical performance testing is implemented throughout the entire process. Field production verification indicates that the automated testing scheme achieves fully unmanned operation, reducing operator demand from 2 to 1. Overall production efficiency is improved by up to 6 times compared to manual testing. Compared with the over original forty types of electrical connectors, the system now uses only 5 specifications of specialized adapters to support automatic testing of over 100 pyrotechnic devices, reducing the number of specifications by more than 85%.
