論文題目：基于PLC的電阻爐控制
摘 要
本文介紹了一種電阻爐的控制方案,從軟、硬件兩方面闡述了系統的組成和功能,主要對溫度控制系統做了介紹。本系統以FP0系列PLC為控制核心,利用PLC的強大功能,首先能順利地進行金屬材料的熱處理工藝,同時電氣裝置也能夠按照設計要求穩定運行。本系統還使用觸摸屏代替普通按鈕，加強了人機互動，既能隨意修改程序段中的數值，又能實現熱處理工藝過程的自動跟蹤和監控，實現熱處理工藝優化。本系統外部電路簡單，控制精度較高，運算速度快，具有微型化和低功耗的優點。 關鍵詞：PLC;觸摸屏;電阻爐;溫度控制
A Resistance Furnace Control Bad On PLC
Abstract
This paper prents the applications of a control scheme in the resistance furnace. It mainly explains the composition and function of temperature control system in software and hardware aspects. Taking FP0 ries PLC as control core, this system can carry out heating process for metallic materials while ensure electrical installations operate stably accordance with the design requirements using the powerful function of PLC. The system also us touch screen instead of the ordinary push button, enhance the interaction between human and computer. It can modify the numerical value in the program gment freely, and realize the optimization of heating process by automatic tracking and monitoring during heating treatment process. The system has the following advantages as simple external circuit, high control accuracy, high computing speed, low power consumption and miniaturization.
Keywords: PLC, Touch Screen, Resistance Furnace, Temperature Control
