导弹测试系统中的高速数据传输技术研究

摘要

导弹舵机测试要求具有高效率、大批量的连续数据传输能力,且总体测试的复杂性和参与测试部件不断增加,所以必须从硬件结构研究高速数据传输技术,同时缓解系统资源消耗压力.研究DMA、缓存、同步触发等高速数据传输技术,基于这些技术构建高速测试系统,并应用于某型导弹舵机频率特性测试及总体测试.理论研究及其应用表明,构建的高速测试系统具有数据流量大,传输效率高,系统资源消耗低,信号处理速度快等优点,可以满足导弹测试的数据传输要求,也可应用于其他有高速数据传输要求的系统.%Missile actuator test requires continuous data transmission capability with high efficiency and huge quantity,and its complexity and participating parts in general test increases gradually, so the high-speed data transmission technology must be studied from hardware while system resources consumption can be alleviated. The technologies of DMA, buffer and synchronous trigger Jn high-speed data acquisition system are researched. Based on them, the high-speed test principle is studied and applied to some missile actuator test The theory and application indicate that the constructed high-speed test system can meet the requirements of mass data flow, high transmission efficiency, low resources consumption and high-speed signal processing, and it can be used to other systems with high-speed data transmission.
