基于消息中间件的三层分布式铁路牵引供电信息系统

Three-layer Distributed Information System Based on Message Middleware on Railway Power Supply Systems

提出了采用基于客户 /消息中间件 /服务器的三层分布式网络结构 ,来开发铁路牵引供电调度信息系统 .首先分析了这种三层结构的模型、特点和优越性 ;然后详细阐述其关键技术消息中间件的设计和实现 ;最后对实际系统实现和投运后的性能指标进行了总结 .

To solve the complex information integration problem of railway power supply scheduling, a three-layer distributed structure based on Client/Message Middleware/Server to develop the railway power supply scheduling system is introduced. First, the model, its characteristics and advantages of the three-layer structure are analyzed. Then the design and implementation methods of the key technique of building message middleware are demonstrated. In the end, system implementation and main functional index are summarized. The introduced method has some applicable value in those information systems, in which there are complex network structures and interfaces.
