实时患者监护需要通信系统在异构医院部署中保持低延迟和高可靠性，同时具备可扩展性。本文提出一种基于中间件的监护系统，使用数据分发服务（DDS）协调分布式医疗组件间的数据交换。系统架构由部署在病房和病区级应用中的模块化DDS域参与者构成，通过分层数据总线结构连接。配置并评估了包括可靠（Reliable）和尽力而为（Best Effort）在内的服务质量（QoS）策略，以研究交付保障与通信开销之间的权衡。开发了原型实现来模拟临床监护工作流程，并开展了与基于套接字（socket）消息传递的对比实验。评估显示，在测试场景中，采用可靠QoS的DDS避免了数据包丢失，在网络负载下比套接字提供更可靠的交付。这些结果支持将DDS作为需要一致数据交付的实时临床通信的实用中间件选项。
英文摘要
Real-time patient monitoring requires communication systems that maintain low latency and high reliability while scaling across heterogeneous hospital deployments. This paper presents a middleware-based monitoring system that uses the Data Distribution Service (DDS) to coordinate data exchange among distributed medical components. The system architecture consists of modular DDS domain participants deployed across patient rooms and ward-level applications, connected through a layered data bus structure. Quality of Service (QoS) policies, including Reliable and Best Effort, are configured and evaluated to examine trade-offs between delivery guarantees and communication overhead. A prototype implementation is developed to emulate clinical monitoring workflows, and experiments are conducted in comparison with socket-based messaging. The evaluation indicates that DDS with Reliable QoS avoids packet loss in the tested scenarios and provides more dependable delivery than sockets under network load. These results support the use of DDS as a practical middleware option for real-time clinical communication where consistent data delivery is required.
