压力机群控系统的设计

文章详细介绍了压力机群控系统的实现，主要任务包括了上位机监控软件的开发、硬
件电路的设计和下位机的编程。系统上位机采用c++ Builder6.0 来进行监控程序的开
发，压力机群整个网络采用RS-485 的通信方式进行数据通信，控制板处理器选用集
成了A/D 和D/A 的高性能增强型MCU—aduc841,并充分的考虑了电磁干扰与可靠性
问题，同时下位机控制程序嵌入了嵌入式实时操作系统uC/OS-Ⅱ，以提高系统的实
时性与可靠性。

Abstract: This paper describe the realization of group control system for presses in detail,
including the development of monitoring software of host computer, the design of
hardware circuit and programming of the slave computer. The monitoring software is
programmed with c++ Builder6.0, the net of the system choose RS-485 communication
protocol; the control board select high-performance MCU—aduc841 which integrate
A/D&D/A and it is designed in the thinking of EMI and reliability fully, meanwhile in
order to improve the real-time and reliability of the system, the slave computer embed
the real time operating system uC/OS-Ⅱ.
