详细介绍了已应用于多个项目中的实时监控程序ＲＭＯＮ。它采用优先级调度算法和中断任务的概念，确保了并行任务的实时性。还介绍了延时算法和定时算法、设备管理和出错处理算法，给出了人机接口和单回路控制器应用两例。ＲＭＯＮ具有积木化和开放式结构，整个监控程序只占用约１Ｋ内存。 The RMON, a real-time monitor that has been applied to many projects, is introduced in detail. It uses the priority scheduling algorithm and the concept of interrupt tasks to ensure the real-time parallel tasks. Also introduced the delay algorithm and timing algorithms, device management and error handling algorithms, given the man-machine interface and single loop controller applications in two cases. RMON has a building block and open structure, the entire monitor only takes up about 1K memory.
