拖拉机作业仿真试验集散控制系统总体设计

A General Design of a Distributed Control System Applied in the Laboratory Simulative System of Tractor Working

介绍了拖拉机作业仿真试验台上的微机集散控制系统。它由一台微机作为上位机 (主机 )、4个80 C196 KC单片机控制模块作为下位机 (从机 ) ,以及处于下位的电涡流测功机控制柜组成。上位机用于集中监测和系统管理 ,下位机用于分散控制。上位机、下位机之间通过 RS 2 32

This paper introduced a distributed control system applied in the laboratory simulative system of tractor working. The system is composed of a PC as host computer and four 80C196KC single chip microcomputer controllers as slave computers, and an electric dynamometer control station situated in slave position as a part of the system. The host computer is used for centralized monitoring and system management, while the four slave single chip microcomputer controllers and the electric dynamometer control station are used for distributed control. The communication between host computer and slave computers is accomplished through their serial ports,RS232C.
