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

为了解决弹载环境下多通道数据实时采集存储以及时序准确控制的问题,采用并行ARM设计,构建弹载多通道高速测试系统。根据弹丸飞行特性和高速采样要求,采用模块化设计,分别对电源管理、存储控制和高速存储进行算法设计,通过霍普金森杆和飞行试验验证了系统时序管理和高速采集存储的正确性。试验结果表明:该测试系统能够在工作时序范围内完成多通道数据的实时采集和存储,满足可靠性和稳定性的要求。

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.
