基于工业以太网的除尘风机节能控制系统设计
|
摘要
为解决卷烟工业现场集散控制系统中不同类型PLC之间无法直接进行数据交互等问题,基于工业以太网技术设计了除尘风机节能控制系统。利用上位机监控站服务器作为转换站点,通过工业以太网平等地将不同PLC接入监控数采系统,实现不同PLC之间的数据通讯。以南宁卷烟厂制丝车间3台除尘风机为对象进行测试,结果表明:采用节能控制系统后,日常生产为节能模式,检修时为旁路模式,两种模式可准确切换;在相同工况下3台除尘风机的节电率均在40%以上,年节电量达2.6万kW,节能效果显著。该技术可为工业现场不同协议PLC之间的数据交互提供支持。
For facilitating data communication between PLCs of different types in on-site distributed control system in cigarette industry, an energy saving control system for dust removal fan was designed on the basis of industrial Ethernet. The monitoring station server of host computer is used as a conversion station, and different PLCs are equally connected to the monitoring and controlling data acquisition system to realize the data communication between the PLCs via the industrial Ethernet. Three dust removal fans in the primary processing department in Nanning Cigarette Factory were tested in the energy-saving control system, normal production worked at energy-saving mode and during maintenance at bypass mode. The results showed that the two modes could be switched from one to the other reliably. Under the same working conditions, the electricity saving rate was above 40%, or 26 000 kW per year. This technology provides a support for the data exchange between PLCs under different protocols in industrial fields.
