摘要
Modbus协议是一种完全开放的通讯协议,广泛应用于各类控制系统和智能仪表设备。结合冶炼厂现场实际情况,将Modbus协议应用于冶炼烟气全流程监控项目中,搭建了基于Modbus的通讯网络,将全厂的DCS控制系统,PLC系统,以及智能仪表设备互相联通,实现互联互通互操作,将烟气的相关数据进行分析和处理,并利用这些数据实现烟气的全流程闭环控制。所提技术为冶炼厂的自动化和信息化建设,提供了数据支持和信息保障,对提高有色冶金企业烟气监控的自动化水平至关重要。
Modbus protocol is a completely open communication protocol,which is widely used in various control systems and intelligent instrumentation.Combined with the actual on-site situation of the smelter,Modbus protocol is applied to the whole process monitoring of smelting off-gas,and a communication network based on Modbus is built to link the DCS control system,PLC system and intelligent instrumentation of the whole plant to each other,realizing interconnection and interoperation.Related data of off-gas are analyzed and processed,and these data are used to realize the whole process closed-loop control of off-gas.The proposed technology provides data and information support for the automation and information construction of the smelter,and it is very important for improving the automation level of off-gas monitoring in non-ferrous metallurgy enterprises.
