摘要:
鉴于物联网(IOT)的应用在医疗行业日益广泛,提出一种适合IOT网络的系统设计方法TOA和对应中间件TOC。TOA将“人”、“物”及所有相关的智能系统都抽象成一个地位完全平等的IOT互联对象,统一了IOT网络环境中联网对象之间的交互模式。在TOC中间件系统设计实现中,采用XMPP协议进行消息交换,利用基于Pipe & Filter的Agent架构模式支持多样异构的智能设备,方便Agent的升级和扩充。通过在某医院医疗垃圾管理系统的成功应用,验证了TOA的设计思想和TOC中间件系统,取得了较好效果。

Abstract:
This paper designs Things Oriented Architecture(TOA) and Things Oriented Communication(TOC) middleware which is consist of device Agent, TOC client, and TOC server. TOC is capable of isolating the innumerable diversity of Internet of Things(IOT) objects and providing a unified interactive service and platform by applying Extensible Messaging and Presence Protocol(XMPP) and Pipe & Filter design mode. It implements TOC in the hospital medical trash management system. The results are very promising. It indicates that TOC can provide a unify system integration platform and enough flexible in IOT objects implementation.
