基于CORBA的分布式多DCS数据采集系统的应用研究

Research on Multi Distributed DCS Data Acquisition System Based on CORBA

DCS系统可以通过不同的数据访问接口将分布式数据快速、有效的融合,使DCS不仅能够对生产设备进行控制,而且也能为生产管理信息系统提供数据支持。CORBA和Web的集成,能够产生性能优于传统的C/S、B/S模式的应用平台,在Web服务器上开发CORBA客户端,对CORBA服务进行调用,实现网关程序对负载进行调度,一方面简化了基于Web的CORBA应用程序的开发,另一方面也提高了服务对Web请求的响应速度。

DCS system through various data access will be rapid and effective integrate the distributed data,so that DCS can not only control the production equipment,but also for the production of management information system to provide data to support.With the integration of CORBA and Web,it can provide a new application platform with more portability and flexibility than the traditional Client/Server and Browser/Server modes.In the Web server on the development of CORBA client,CORBA services to make calls,and the gateway to load dispatching procedures,on the one hand simplifies the CORBA Web-based application development,while improving the services on the Web respond to requests for speed.
