配置、電路圖的設(shè)計、程序設(shè)計,控制對象數(shù)學(xué)模型的建立、控制算法的選擇和參數(shù)的整定、人機界面地設(shè) 計等。各種溫度系統(tǒng)都有自己的優(yōu)缺點,用戶需要根據(jù)實際需要選擇系統(tǒng)配置。隨著生產(chǎn)力 的發(fā)展和對溫度控制精度的要求不斷提高,溫度控制系統(tǒng)的控制技術(shù)得到了迅速發(fā)展。PLC master- slave control construction, constitutes an economic and reliable industrial heating furnace temperature control system. The furnace temperature control system is a large inertia system, generally uses the PID algorithm to control, and uses ladder diagram programming language of PLC to programme, in order to carry out the automatic control of the heating furnace work process. Using the configuration software KingView to design the upper puter interface to monitor the control system and realtime sample and process. It is able to get a friendly user interface, is a realtime temperature control system which has moderate application value. After the design, the system has a good stability, a high precision and a strong robustness. 【 Key words】 The heating furnace PLC PID Temperature control The upper puter 啊啊啊啊
