摘要
介绍了无线射频技术及其在物品信息网中的应用,并针对将无线射频技术用在物品信息网中产生的海量数据难以处理的情况,设计了一种基于事件状态变化的数据过滤算法。该算法主要参考了Auto-IDCenter制订的SavantSpecification1.0,以其中提到的Savant为中间件的构架。算法靠功能列表和事件队列维护信息,过滤阅读器上报的重复信息,只向上层应用报告关于标签出现、消失等状态变化情况,采用gsoap工具包实现规范中要求的soap通信功能,并结合上层应用,实验证明算法的可行性。
The radio frequency identification and its application in the electronic product code system are introduced. To resolve the problem of processing great number of data produced in the electronic product code system, a data filter method is designed, which based on the event status change. And the middleware that complied with savant specification 1.0 is designed, which worked out by auto-ID center. This method used function lists and event queues to manage information. It removed redundancies and only report status changes of tags （for example, tag appeared or tag disappeared） to upper layer application. The method used gsoap tool to complete soap communication that specified in the savant specification 1.0.with upper layer application. At last combined with the upper layer application, experiment proved the feasibility of the method.
