基于标准SQL的RFID中间件技术研究

Research of RFID Middleware Based on Standard SQL

以数据库为中心,基于标准SQL,设计RFID中间件,利用标准SQL对各种语言和应用系统的支持,解决对底层硬件和上层应用的连接。在数据库中完成数据的采集、过滤、聚合操作,摒弃了ALE的复杂结构,降低了开发与部署成本,适用于中小企业快速推广RFID技术使用。此系统数据采集速度快,支持多种通信模式和数据格式,耦合度低、易于扩展。

According to the database, a Radio Frequency IDentification（RFID） middleware was designed based on the standard SQL. For the standard SQL support for various languages and application systems, the connection between the underlying hardware and upper layer application system become available. Be- cause the complex structure of ALE is abandoned, and accomplish, filtering, aggregation of the data were operated in the database ,the cost of development and deployment was reduced, it＇s suitable for small and medium-sized enterprise using RFID technology. The middleware has many features, for instance, high speed data acquisition, multiple communication mode and data format, low coupling, easy extension.
