嵌入式环境下Web Service技术的实现

为了解决嵌入式系统与其他异构系统之间互联和集成的难题,提出了Web Service技术在低端嵌入式设备上的实现方法。以ARM Cortex-M3微处理器为核心,基于小型实时操作系统和嵌入式TCP/IP协议栈,详细阐述了Web Service的实现过程,包括HTTP接收,XML与SOAP协议的解析,以及同具体服务实现的绑定,并针对嵌入式环境下资源受限的特点,给出了相应的优化方法。使用专用测试软件进行的压力测试表明,该实现运行稳定,具有良好的可行性。

Implementation of Web Service Technology in Embedded Environment

To cope with the interoperability and integration between embedded system and other heterogeneous systems,a new approach of applying Web Service technology in low-end embedded equipments is proposed.Based on ARM Cortex-M3 microcontroller,miniature realtime operating system and embedded TCP/IP protocol stack,the implementation process of Web Service is elaborated,including HTTP message reception,XML/SOAP protocol parse and service function bind.Special care is taken to minimize resource consumption in this r...
