基于MCGSE的盘管温度控制系统设计

温度作为工农业生产的重要被控对象之一,一直是人们研究的主要对象.设计中选用在MCGS通用版的基础上开发的嵌入式组态软件MCGSE,对现场数据进行采集处理,融合动画显示、报警处理、流程控制和报表输出等功能,更方便用户解决实际工程问题,广泛应用于自动化领域.控制芯片选用可编程序控制器（PLC）S7-300,拥有模块化结构,配置易于分布式实现,电磁兼容性较好,能抗震动冲击,在多数实际工业控制场合满足需要,经济上也很可观.设计中选取盘管出水口温度作为控制对象,采用PID算法达到稳定、快速、准确的要求.

Pipe Temperature Control System Based on MCGSE

Temperature is one of the most important object of industrial and agricultural production which has been researched for many years.The SCADA （Supervisory Control and Data Acquisition） called MCGSE which developed based on the MCGS is used for collecting and processing the field data in the system,containing the functions of integration of animation display,alarm processing,process control and report output and other functions.It is convenient for the user to solve practical engineering problems so that it is widely used in the field of automation.The micro controller of the system is Programmable Logic Controller（PLC for short）-S7-300,which has a modular structure and is easy to distributed control.As a PLC,the S7-300 has the ability of anti-electromagnetic interference and resistance for shocking,which is very impressive and good to use for meeting the requirements of performance indicators in most of the actual industrial control applications.The temperature of water from the pipe is selected as the controlled object,which can be stable,rapid and accurate in control of PID.
