摘要
极向场电源控制对操作系统实时性要求不断提高,有必要对其操作系统进行实时性能测试;极向场电源控制使用的是QNXRTOS,采用软件编程和硬件辅助协同的方法进行测试,给出了线程切换时间和中断延迟时间的具体测试流程并对测试结果进行分析;测试结果表明QNX RTOS满足极向场电源控制系统实时性要求;并且该测试方法具有一般性,可以用来对QNX系统其他实时性能进行测试。
As poloidal field power supply control system needs increasing high-performance of real-time operation system,it is necessary to test the performance of operation system.This paper tests Poloidal field power control system that adopts QNX RTOS(Real Time Operating System),using software programming and hardware-assisted collaborative approach.We introduce the specific testing procedures of thread switch time and interrupt time and analyze the test results.The results show that the QNX RTOS meet the real-time requirements of poloidal field power supply control system.It's a general measuring method and can be used for other relative testing.
