电热隧道窑炉温自动化测控系统的研究

A Study on Automatic Measurement and Control System of Electrothermal Tunnel Kiln

介绍了一种由计算机、智能仪表等组成的自动化电热隧道窑炉温测控系统。这套系统不仅可随时将炉内各点温度记录、存储备查,同时还可通过计算机模拟将炉内各点温度分布曲线通过显示器显示出来,并能与预先设定的曲线进行比较,实现超温报警、断偶显示等功能,且在高温恒温区采用多点控制。

The automatic measurement and Control system of electrothermal tunnel kiln,which is Composed of Computerand intelligent instrument,was introduced.Inthis system,the dot temperature is recorded and saved at any time,in the meanwhile,the kiln temperature Curve is imitated and Compared With the predetermined Curve.In addition,the system will alert the operator when kiln temperature exceeds the predetermined value and can display the information of the thermocouple that is disconnected.The multl dot controlol method which made the Control Curve more reasonable was adopted.
