摘　　要：为了能够实现不同现场总线设备之间的互联和互操作,简化基于现场总线的系统开发过程,同时又能保证系统的实时性能,研究并提出了一种新的嵌入式系统下多现场总线融合的实时中间件实现方案。该方案参照Minimum CORBA和Real-tim eCORBA中间件的规范,实现了基于RTLinuxPro实时操作系统的嵌入式实时中间件,同时借鉴了软插件的设计思想,不仅使该实时中间件系统的实时性能显著提高,而且使得该系统具备了良好的可扩展性,实现现场总线的热插拔。To implement the intercommunication between different kinds of field-bus, simplify the development process and meet the real-time demand of the whole embedded system, an improved embedded system field-bus real-time middleware is presented. The system is based on the standards of minimum CORBA and real-time CORBA, and RTLinuxPro the hard real-time operating system. The software plug-in framework is also applied in the middleware. Favorable real-time performance and well-designed extensibility are demonstrated. And the hot-plug function of many field-bus devices is realized.
