摘要:

在远程监测系统的上位机数据监测软件的设计中,上位机要对工业现场机器的运行情况进行实时监测,只有解决了和底层控制设备通信问题,才能实现对工业现场数据的实时采集,进而实现数据的存储、动态曲线的显示和数据报警等功能。在Visual Studio2012运行环境下,运用.NET技术,实现上位机数据监测软件与S7300之间的工业以太网通信。结合某企业铝轧机的应用需求,对基于西门子 S7300/400系列 PLC的远程监测系统进行了相关的研究与设计,通过工业以太网通信方式,上位机数据监测软件可以监测 S7300 PLC采集的铝轧机轴承温度、油雾风机速度、供油泵压力等参数,实验结果表明,软件能够实时地采集数据和控制工业现场的设备。

Abstract:

The remote monitoring system requires the realtime monitoring of the operation of the industrial field machine. Not until the communication problem of the underlying control equipment is solved can the realtime collection, storage, dynamic curve display, data alarm and other operations of the industrial field data be achieved. In this paper, the industrial Ethernet communication between the upper machine data monitoring software and S7300 is under the environment of Visual Studio2012 and supported by the .NET technology. And the remote monitoring system based on Siemens S7300/400 series PLC is studied combined with the application requirements of an enterprise of the aluminum rolling mill. Through the industrial Ethernet communication mode, the PC data monitoring software can monitor S7300 PLC to collect the aluminum rolling mill bearing temperature for the oil pump, oil mist fan speed, pressure, etc. Experiments verify that our software can collect realtime data and control the industrial field devices.

Key words: remote monitoring, industrial ethernet, TCP IP, PLC
