Abstract: Considering the higher system requirements and the problem of slower access speed when the wireless embedded medical devices interact with database, this paper put forward a middleware that made wireless embedded devices interact with hospital database based on Socket and XML. This middleware established the communication link with embedded device by Wi-Fi, worked by receiving the request from wireless embedded devices to access the database, and converted the result set to XML document then returned back to the wireless embedded device. The experimental results show that this middleware can solve the interaction problem of wireless embedded devices and database in various operating systems and achieve higher efficiency.

摘要： 针对目前无线嵌入式医疗设备与网络数据库交互存在系统要求较高、速度较慢等问题，基于Socket及XML技术，提出了一种无线嵌入式设备与数据库交互的中间件系统。在Wi-Fi网络环境下，该系统采用Socket技术，接收嵌入式设备访问数据库的请求并对数据库进行操作，按指定的格式将获得的数据结果集转换为相应的XML文档并回送于嵌入式设备。实验结果表明，该中间件系统能有效解决多种操作系统平台下的无线嵌入式设备与网络数据库的交互问题，整体实现效率较高。
