設計了一套反應釜計算機控制系統(tǒng)，用以實現(xiàn)反應釜配料比值控制，以及反應釜溫度
—夾套溫度串級控制。選用研華工控機、RS232/485 轉(zhuǎn)換模塊，以及支持MCGS 組態(tài)及通
信功能的天辰智能儀表組成硬件系統(tǒng)；用MCGS 工控組態(tài)軟件編寫控制程序。實際運行結(jié)果表明，該系統(tǒng)能夠按照工藝要求正常運行，串級控制系統(tǒng)調(diào)節(jié)精度高，可靠性和工作效率均優(yōu)于簡單控制系統(tǒng)。

Abstract: A computer control system for reactor has been designed for realize materiel-allotment ratio control, and the string control about the Reactor temperature-interlayer temperature. Hardware system is composed of YanHua IPC, RS232/485 transitional module,and TianChen intelligent meters which support MCGS configuration and communication function;Using MCGS industrial control configuration software write the control programs.The practical running results indicate that the system can runs normally according to the technical requests, string controlling system has high adjustive precision, and its reliability and work efficiency are excelled the simple controlling system.
