电力负荷监控系统双微机工作方式研究

A Power Load Monitoring System with a Dual-Microcomputer

以湖北省推广应用的无线电力负荷监控系统为例,论述了双机可靠性的设计思想、双机系统的硬件和软件结构、双机通信、双机同步、双机切换和DOS环境下软件设计等有关问题.提出了以文件为中心的双机系统数据一致性、功能命令一致性和键盘操作一致性的实现策略.

With the radio power load monitoring as an example, the dual-microcomputer design, including the reliability design idea, the structure of hardwares and softwares for the dual-microcomputer , the synchronization, the fault switching and software design under thd communication and DOS environment are discussed. For a dual-microcomputer system with files as its center, the strategy for realizing data consistence, function command consistence and keyboard operation consistence are proposed. Specific features of the system for guaranteeing continued and reliable operation are described.
