一种远程监控系统结构的设计与实现

传统基于分布式对象模型的远程监控方法具有互操作性差、缺少灵活性、非防火墙友好等缺点.为了克服这些不足,提出了一种基于Web Service的远程监控系统结构.该远程监控结构利用OPC技术获取现场数据,通过过程网关将这些数据封装为Web Service,利用Web来建立远程监控系统.为了保证系统的安全性、可靠性,采用了安全审查、权限管理、冲突避免、日志管理等措施.最后,在这种远程监控系统结构的基础上,开发了一个远程监控系统的示例.系统实际运行效果表明,这种远程监控方式有其独特的优点.

Design and Implementation of a Remote Monitoring System Architecture

The traditional remote monitoring technology based on distributed object models has the disadvantages,such as lack of cooperation, lack of flexibility,and firewall friendlessness.To solve these problems, a remote monitoring system architecture based on Web Service was proposed.The architecture has used OPC technology to acquire the field data.The data is encapsulated as Web services in process gateway.Web is adopted to build remote monitoring systems.To assure systems' security and robustness,the architecture has provided some functions like security investigation,authority management,conflict avoiding,log management and so on.An example built on the remote monitoring architecture was given in the paper.The running of the example shows the characteristics of the architecture.
