STRS系统异构处理器通信中间件的设计与实现

Design and implementation of communication middleware of heterogeneous processors in STRS system

针对空间通信无线电系统(STRS)异构处理器间通信存在的实时性不高、冗余度较大、无法故障恢复等问题,将分布式数据分发服务(DDS)中间件技术引入到STRS架构中,实现STRS异构处理器波形应用组件之间基于发布/订阅模式的通信中间件。在完全兼容STRS标准规范的前提下,有效地提高了基于STRS的通信系统消息传递的实时性,降低了系统的复杂度和冗余度,提高了开发效率,节省了系统的开发和维护成本,实现了全局和局部模块的动态重构。

Aiming at the problems of low real-time performance,large redundancy,and inability to recover from faults in the communication between heterogeneous processors in the Space Telecommunication Radio System(STRS),the distributed data dis‐tribution service(DDS)middleware technology is introduced into the STRS architecture to realize the publish/subscribe modebased communication middleware between the STRS heterogeneous processor waveform application components.Under the prem‐ise of being fully compatible with the STRS standard specification,it effectively improves the real-time performance of the com‐munication system based on STRS,reduces the complexity and redundancy of the system,improves the development efficiency,saves the development and maintenance costs of the system,and realizes the dynamic refactoring of global and local modules.
