【摘要】 针对目前OPC(Object Linking and Embedding for Process Control)组态软件大多只限于本地的监视和控制的情况,通过采用基于Web服务的OPC XML-DA新技术,设计了远程监控系统,使得远程用户可以使用浏览器或定制的客户端通过互联网或局域网实现对现场的远程监控。由于采用了标准的OPC接口和Web服务调用接口,方便了系统的扩展和升级。该系统已在变电站监控系统中成功地应用,结果证明,它满足了用户对远程监视和控制的需求。更多还原

【Abstract】 To the problem that,at present,OPC configuration softwares are mostly limited to local monitoring,a method of implementation of remote monitoring system based on OPC XML-DA technology is presented.Remote users can use IE or custom-built client to watch and control the local status through the Internet or Intranet.Because of using OPC standard interface and web service interface,the system can be easily expanded and upgraded.This system is used for monitoring system in the transformer substation.The practical results show that it satisfies user’s need for remote control.更多还原
