可编程控制器是一种应用很广泛的自动控制装置，它将传统的继电器控制技术、计算机技术和通讯技术融为一体，具有控制能力强、操作灵活方便、可靠性高、适宜长期连续工作的特点，非常适合温度控制的要求。21648
在工业领域，随着自动化程度的迅速提高，用户对控制系统的过程监控要求越来越高，人机界面的出现正好满足了用户这一需求。人机界面可以对控制系统进行全面监控，包括过程监测、报警提示、数据记录等功能，从而使控制系统变得操作人性化、过程可视化，在自动控制领域的作用日益显著。
本文主要介绍了基于西门子公司S7-200系列的可编程控制器和亚控公司的组态软件组态王的训练室温度控制系统的设计方案。编程时调用了编程软件STEP 7 -Micro WIN中自带的PID控制模块，使得程序更为简洁，运行速度更为理想。利用组态软件组态王设计人机界面，实现控制系统的实时监控、数据的实时采样与处理。实验证明，此系统具有快、准、稳等优点，在工业温度控制领域能够广泛应用。

Abstract
Fire smoke indoor heat training room for requirements on training of the real-time data monitoring，including the collection, sorting, transmission（Between IPC and PLC）；And the integrated control field device.The training of indoor temperature monitoring and control is a very important component.In order to make the training room effect is distinct，to improve the training intensity.The general environment temperature can be increased to 30 to 70 ℃ or so.
Programmable Logic Controller (PLC) is a kind of automatic control equipment which is widely used in the industrial manufacture. It merges the traditional control technology, computer and communication technologies with a strong ability to control, flexible operation, high reliability and suitable for long-term characteristics of continuous work. It is very suitable for temperature control requirements.
In the industrial field, with the rapid increase in the degree of automation, it is more and more important to monitor the process of control system for the users. The emergence of human-machine interface meets the needs of users. Man-machine interface can comprehensively monitor the control system, including process monitoring, alarm, data logging and other functions, so that the control systems have become user-friendly operation, the process of visualization and it will play more and more important part in the field of automatic control.
This essay mainly introduces a design of temperature control system with SIMATIC programmable logic controller (PLC) and configuration software Kingview which is developed by Beijing Yakong Company. When programming, we use the PID control arithmetic software module which is contained in the program software STEP 7 -Micro WIN so that the program looks easier and operates more quickly. In order to monitor the control system and process data in actual time, we designed Human MachineInterface(HMI)with the configuration software Kingview. The result of experiment proves that this temperature control system could run quickly, accurately and have good stability, which is the advantage of the control system. This control system has been widely used in the industrial temperature control field.
With the continuous development of automatic science and technology, high-precision, intelligent, user-friendly temperature control system is the inevitable trend of development at home and abroad.
