CORBA技术在分布式测控系统中的应用

Application of CORBA technology in distributed measure-control system

探讨了应用分布式对象计算技术CORBA解决现场控制层与其他层的信息交换问题,提出了基于CORBA的分布式控制系统实现的框架结构。讨论了底层CAN总线局域网,利用CORBA中的ORB使CORBAServer与CORBAClient在逻辑上实现分离的特性,用CORBAServer作为这个局域网与其它网络通讯的网关;在应用层,应用了CGI技术,把WebServer与CORBAClient集为一体,实现了远程WebClient与WebServer的交互功能,从而实现了CORBA技术在分布式远程测控系统中的应用。

The author studies the application of CORBA technology in solving the communication between the field control layer and another layer in distributed control system, and presents the framework of the CORBA-based distributed control system. In the field layer, the CAN-bus LAN is discussed. Using the character of separating CORBA server and CORBA Client by the ORB in the CORBA system, CORBA server is the gateway between the LAN and others. In the application layer, by using CGI, the Web server and CORBA client are integrated together, and the remote communication is realized between Web Server and Web client. The application of CORBA is realized in distributed remote measure-control system successfully.
