基于CORBA及多层C／S模式的分布式软件控制系统

针对某大型实验装置分布式计算机控制系统,为增加服务端程序的可移植性、可维护性,减轻客户端的开发难度,对传统的两层C/S模式进行层次重构,采用分布式软件技术及三层C/S控制模式能够实现子系统设备的有效控制及信息数据的实时传输,应用中间件CORBA技术能实现网络通讯的平台及地域无关性.实践表明,CORBA及多层C/S控制模式的分布式软件控制系统是大型实验装置理想的软件控制方案.

Research of Distributed Control Software System Based of CORBA and Multi-layer C/S Mode

For the distributed control system of some large-scale experiment equipment,in order to enhance transplant and maintainability of server program and debasing exploitation difficulty of client,the traditional two-layer C/S control mode is reconstructed in terms of hierarchy.Effective operation and real-time transmitting datum can be implemented with distributed software technology and C/S control mode.Irrespective characteristic of platform and field for net communication can be implemented with mediate CORBA technology.The application example shows that three-layer C/S distributed control mode for CORBA is a good software control scheme for large-scale experiment equipment.
