自动控制系统(DCS)在制糖工艺中的应用

The Application of Automatic Control System (DCS) in Sugar Refining Process

以某糖厂糖线制糖工艺自动控制系统(DCS)为例,简述DCS系统的设计思路及实施方案.DCS系统负责对整个生产过程的输入、输出进行监视、控制、显示、报警、记录和存档,并在控制室实现工艺生产的全过程控制,即正常运行工况下的监视和控制以及异常工况下的报警和紧急事故处理.

This papertakes the automatic control system(DCS)of sugar production process ofa sugar mill as an example,and briefly describes the design idea and implementation scheme of DCS system.DCS system is responsible for monitoring,controlling,displaying,alarming,recording and arehiving the input and output ofthe whole production process,and realizes the whole process control of process production in the controlroom,that is,the monitoring and control under normal operation conditions and the alarm and emergency treatment under abnormal conditions.
