摘　　要：针对目前高校测控实验仪功能单一,对测控系统的可靠性、实时性等不能很好地模拟等问题,研究和设计了一套配电测控模拟实验台,由上下位机系统构成。下位机以工控机为核心,配装简化的多任务实时操作系统,能够对16路开关量、64路模拟量及多个键盘任务进行实时检测和控制,并能够和上位机进行定时通信,将收集数据及时传送给上位机,进行汇总、分析和报表打印等。重点分析了下位机的实时多任务之间的关系,调度过程原理及简化的多任务实时操作系统的设计。Because of the poor function of the current universities monitoring and control laboratory system, it isn＇t satisfied to study reliability and real-time simulation. To meet our needs and work out such issues, we design a power disturbing measure and control lab simulation system which is consisted of server-client system, based on industry control PC and simplified multitask RTOS. The client system is able to measure and control as much as 16 ch digital and 64 ch analog signals, as well as some keyboard input tasks in real-time, and the client system is also able to communicate with server timely collected data will be transmitted to the server in time for summary, analysis and report. The paper focuses on the real-time multi-tasking relationship of the client, the principle of the process scheduling and design of simplified multi-tasking real-time operating system.
