现场总线在水泥生产线中的应用极大方便了现场设备与控制系统间的通讯,其主要有三种应用形式:1)水泥生产线的许多设备有配套的控制装置,控制程序由设备生产厂家编写,DCS控制系统仅控制设备的启停,读取设备运行时的参数;2)大量仪表采集到的数据被送入DCS中进行处理,作为设备的连锁条件,当温度或压力超过设定值时跳停设备防止事故进一步扩大,同时数据在操作站上显示;3)控制系统
The application of field bus in cement production line has greatly facilitated the communication between field equipment and control system. There are mainly three application forms: 1) Many equipments in cement production line have matching control devices, and the control procedures are written by equipment manufacturers. DCS The control system only controls the starting and stopping of the equipment and reads the parameters of the equipment running; 2) The data collected by a large number of instruments are sent to the DCS for processing as the chain condition of the equipment, and the equipment will stop when the temperature or pressure exceeds the set value Equipment to prevent further expansion of the accident, while the data displayed on the operating station; 3) control system
