Missile-borne Multi-channel High Speed Test System Based on Parallel ARM

In order to solve the problem of high-speed real-time acquisition and storage of multi-channel data in missileborne environment and accurate control of time sequence, a multi-channel high-speed testing system was constructed withparallel ARM. According to the flight characteristics and high-speed sampling requirements of the projectile, a high-speeddata acquisition and storage system including storage control module, signal acquisition module and power managementmodule are designed to realize high speed data storage. The correctness of timing management and high speed acquisitionperformance of the system are verified by Hopkinson bar test and flight test. The results show that the system can completethe real-time acquisition and storage of multi-channel data within the working time range, and can meet the requirements ofreliability and stability.
