活性炭项目自动控制系统的设计

摘要

针对现有活性炭项目生产线因无法实时监控活性炭产品生产过程中的相关工艺参数而导致的所需人力多、产品质量波动大、产率低的问题,介绍了一种活性炭项目自动控制系统的构成、网络结构及人机界面设计.该系统通过工业以太网和现场总线技术将活性炭项目中各生产自动化子系统整合,实现了整个活性炭项目生产工序的顺序控制、闭锁联动、参数采集以及关键工艺参数的实时监控、关键工艺环节的自动调节功能.实际应用验证了该系统的可行性和有效性.%In order to solve problems of many manual labors required, unstable production quality and low production rate because correlative parameters cannot be real-timely monitored in producing process of active carbon production of existing production lines of active carbon, the paper introduced composition,network structure and design of man-machine interface of an automatic control system of active carbon project. The system integrates producing automatic subsystems of active carbon project through industrial Ethernet and field bus technologies and realizes functions of sequential control, close-down linkage,parameter collection, real-time monitoring of key parameters and automatic adjustment of key links of whole active carbon project. The actual application verified the system's feasibility and validity.
