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