摘要: 设计基于Windows系统的精确定时与多任务协调处理相结合的实时仿真测试系统。采用FPGA控制的PCI设备定时触发计算机外部中断的方法实现系统精确定时。按照由高到低的执行优先级,重新排列指令的发出、解析、存储等任务的执行顺序,避免出现定时中断无法响应的情况。实验结果证明,系统定时精度可达0.1 ms,测试任务均能按时执行、及时解析并正确储存,满足空间光学遥感器控制系统的实时仿真测试要求。

Abstract: A real-time simulation and detection system for control system of space optics remote sensing device is designed based on precise timing and multitask proportion method in Windows OS. Through external PCI device controlled by FPGA touching the computer external interrupt periodically, precise timing is realized. For work tasks order of transmitting, parse and saving is arranged newly by rule of PRI from high to low. Experimental results show that timing accuracy achieves 0.1 ms. All tasks can be executed punctually, parsed immediately and saved accurately, requirements of real-time simulation and detection are satisfied.

Key words: space optics remote sensing, simulation and detection, precise timing, multitask
