摘要
温度在现代工业生产制造中是一项很重要的工艺参数，广泛应用于工业生产的各种场合，如冶金、钢铁、铸造、食品、化工等各种环境，随着信息的发展，很多场合需要对这一工艺参数进行实时监控，查看历史，制作报表等，以便更好的分析生产中的情况。
传统的高精度温度监测控制一般是用高精度温控表，这种方式成本低，连接简单但是存在控制精度差，信息单一等缺点，无法满足系统化监控的效果。还有很多场合是基于单片机控制的，然而单片机控制的DDC 系统软硬件设计较为复杂, 特别是涉及到逻辑控制方面更不是其长处。
PLC（即可编程控制器）在工业控制领域内得到十分广泛地应用。PLC是一种基于数字计算机技术、专为在工业环境下应用而设计的电子控制装置，它采用可编程序的存储器，用来存储用户指令，通过数字或模拟的输入/输出，完成一系列逻辑、顺序、定时、记数、运算等确定的功能，来控制各种类型的机电一体化设备和生产过程。
本设计是利用西门子S7-200PLC采集温度数据加以计算处理，而后通过昆仑通泰（MCGS）人机界面的显示温度检测系统。完全可以应用于需要监控显示，信息采集报表制作的场合。

Abstract
The temperature in the modern industrial production is a very important process parameters, widely used in industrial production on various occasions, such as metallurgy, steel, foundry, food, chemical environment, with the development of information, many occasions requireon the process parameters in real time, view a history of making statements, in order to better analysis of the production
The traditional high precision temperature monitoring and control is commonly used in high precision temperature control table, this way of low cost, simple connection but has poor control accuracy, information and other shortcomings of the single, can not meet the system of monitoring result. There are many occasions are based on single chip microcomputer control, however, SCM control system hardware and software design of DDC is relatively complex, especially relates to the logic control more than their strengths.
PLC (programmable controller) in the field of industrial control has been very widely used. PLC is based on a digital computer technology, specifically for the industrial application environment and the design of the electronic control device, it uses a programmable memory, used to store a user's instruction, through digital or analog input / output, complete a series of logic, sequence, timing, counting, operations and other defining features, to control various types of mechanical and electrical equipment and integrated production process.
This design is the use of Siemens S7-200PLC collecting temperature data to be calculated, and then through the Kunlun Winton (MCGS) human-computer interface display temperature detection system. Can be used to monitor display, information collection and reporting
