针对物联网(IOT)发展所面临的层次间耦合性高、重用性低、海量数据处理难的问题,提出一种基于Web服务物联网中间件模型,采用XML文件实现配置与执行逻辑分离,利用物联网中“物”的应用属性为划分功能逻辑实现功能模块化,运用负载均衡实现分布处理海量数据,以角色权限设定确保信息安全.实验结果表明,该中间件模型降低了对物联网网关类型的依赖性,提高程序的复用性,实现了万级数据量的处理.根据该模型研发的中间件系统在车辆监控应用中,降低了应用开发成本,提高开发效率,并体现了系统的灵活可配置的实用效果.%To solve the problems in Internet of Things (IOT),such as high coupling between levels,low reusability and massive data processing difficulty,this paper proposed a Web service-based middleware model of IOT.It used XML file to configure and implement logical separation,achieved function modularization by the application of " object" in IOT,distributedly processed massive data by load balance,and ensured information security by role permissions setting.The experimental results show that,the middleware model reduces reliance on the type of gateway,improves the reusability of the program and achieves ten-thousand data processing.According to the application of middleware system developed by the model in the vehicle monitoring,the cost of development is reduced,the efficiency of development is improved and the system has a flexible configuration.
