无线射频识别技术在医疗垃圾管理系统中的应用

Design and Implementation of a RFID Middleware in Medical Trash Management Information System

RFID系统在医疗行业应用日益广泛,提出了一种RFID中间件系统的设计,系统由设备管理代理和事件过程管理器组成。事件过程管理器采用一种依赖时序的、基于Petri网的RFID复杂事件检测方法和基于订阅/发布的服务机制。另外,中间件系统能屏蔽低端各种RFID物理设备的多样性,为企业级应用提供动态灵活部署框架。通过基于该中间件技术的医疗垃圾管理系统的成功应用,验证了该中间件系统的设计,也明显改善医疗垃圾处理环节的监控和管理力度,提升了医院的信息化水平。

In this paper, we design a RFID middleware which is consist of device agent system and event server. The middleware is capable of isolating the innumerable diversity of RFID reader and providing a unify events notification service by applying a detection methods of RFID complex event, based on Petri network. Moreover, we implement the middleware in the hospital medical trash management system （MTMS）. The results are very promising indicating that （1） the middleware providing enough flexible in RFID hardware choosing and system integration and （2） the RFID middleware based MTMS system improved medical trash supervising ability dramatically.
