文章詳細介紹了壓力機群控系統(tǒng)的實現(xiàn)，主要任務(wù)包括了上位機監(jiān)控軟件的開發(fā)、硬
件電路的設(shè)計和下位機的編程。系統(tǒng)上位機采用c++ Builder6.0 來進行監(jiān)控程序的開
發(fā)，壓力機群整個網(wǎng)絡(luò)采用RS-485 的通信方式進行數(shù)據(jù)通信，控制板處理器選用集
成了A/D 和D/A 的高性能增強型MCU—aduc841,并充分的考慮了電磁干擾與可靠性
問題，同時下位機控制程序嵌入了嵌入式實時操作系統(tǒng)uC/OS-Ⅱ，以提高系統(tǒng)的實
時性與可靠性。

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.
