基于软PLC和Web的现场总线远程监控

REMOTE SUPERVISORY OF FIELD BUS CONTROL BASED ON SOFT PLC AND WEB

以互联网实现对远程控制的监控已成为工业控制的新趋势。在基于软PLC和现场总线技术的基础上,给出了通过Web对远程的控制过程进行监控的解决方案,在其中采用多层结构和Web服务技术提高了系统的性能,实现了在现场总线网络内网与Internet外网之间的信息交换。基于软PLC和Web的现场总线远程监控是一种有效的工业自动化和管理信息化的集成解决方案。

There is a new tendency in industrial control that to implement supervisory on remote control with Internet. On the basis of soft PLC and field bus technologies, this paper presents a solution of supervising remote control process through Web technology. Muhilayer and Web Service technology are applied in it to enhance system performance, the information exchange between the intranet of the field bus and the Internet is achieved. The conclusion is that remote supervisory of field bus based on soft PLC and Web is an effective integrated solution for industry automation and management informatisation.
