摘　　要：根据某军用雷达所用开关电源的要求,设计了一种安全可靠的开关电源检测系统。分别介绍了各个外部扩展模块的电路以及主要模块的驱动程序,最后分析了系统实时操作的实现,讨论了系统的资源分配,提出了驱动程序和操作系统的优化方案。该检测系统充分利用LCD附带的存储器,实现了缓存机制,提高了工作的安全性和实时性。投产后的使用表明,该检测系统运行稳定可靠。In accordance with the requirement of the switching power supply used in military radar, a reliable and safety test system for switching power supply has been designed. The circuits of each external expanding modules and the driving program of main modules are introduced respectively, the implementation of real-time operation of the system is also analyzed, the allocation of system resource is discussed ; and the optimal scheme of driving program and operating system is proposed. The system fully uses the attached storage of LCD to implement buffering mechanism for enhancing the security and real-time performance. The operation of final product shows that the system runs stably and reliably.
