基于Profibus-DP的水泥自动配料系统设计

针对某水泥厂配料生产线使用的PLC控制系统存在连线多、距离远、故障点多等缺陷,提出了一种基于Profibus-DP的水泥自动配料系统的改造方案,详细介绍了系统的硬件与软件的设计。该系统以西门子S7-300 PLC为主控制器,具有配料系统运行状态监控、运行异常报警、运行参数修改、实时数据自动生成、历史数据报表查询或打印等功能。

Design of Cement Automatic Batching System Based on Profibus-DP

In view of existing defects of PLC control system used in cement batching production line of a cement plant,such as many connections,long distance,many fault points and so on,the paper proposed a reform scheme of cement automatic batching system based on Profibus-DP,and introduced design of the system's hardware and software in details.The system takes Siemens S7-300 PLC as main controller,which has functions of running condition monitoring,unusual running warning,running parameter revision,real-time data automatic production and inquiry or printing of historical data's report.
