论文题目：基于PLC的电阻炉控制
摘 要
本文介绍了一种电阻炉的控制方案,从软、硬件两方面阐述了系统的组成和功能,主要对温度控制系统做了介绍。本系统以FP0系列PLC为控制核心,利用PLC的强大功能,首先能顺利地进行金属材料的热处理工艺,同时电气装置也能够按照设计要求稳定运行。本系统还使用触摸屏代替普通按钮，加强了人机互动，既能随意修改程序段中的数值，又能实现热处理工艺过程的自动跟踪和监控，实现热处理工艺优化。本系统外部电路简单，控制精度较高，运算速度快，具有微型化和低功耗的优点。 关键词：PLC;触摸屏;电阻炉;温度控制
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
