本文介绍一种由管理计算机(TP805)和控制计算机(TP801B)构成的两级微型计算机群控设备的跟踪图示系统。描述了系统的组成、数据结构、信息流图和软件结构。群控对象的多路实时过程参数借助于双机通讯传送到管理计算机,并建立数据文件。系统在实时时钟管理下,由汇编语言图示软件在CRT上进行动态跟踪图示或静态的曲线重现;可方便地进行选择通道显示、拷贝打印曲线和参数,且实时性强,便于生产过程的监督管理。
This article describes a tracking computer system (TP805) and control computer (TP801B) composed of two-level micro-computer group control device tracking system. Describes the system’s composition, data structure, information flow diagram and software structure. The multi-channel real-time process parameters of the group control object are transmitted to the management computer by double-machine communication and a data file is established. System in real-time clock management, the assembly language graphics software on the CRT dynamic tracking icon or static curve reproduction; can be easily selected channel display, copy the print curve and parameters, and real-time, easy to manufacture Supervision and management.
