基于物联网技术的供水信息系统设计与实现

摘要

Through analyses of the region water supply technical process as well as the collection of information and the management business in the process, a water supply information system is designed and realized based on intemet of things. In the development of application system, for wireless network, frequent disconnect high-delay, low reliability, and other characteristics, Web services technology is used to constructed a hierarchical model of wireless computing software, and focus on Wireless environment use of WSE to ensure security. System performance is improved by asynchronous Web services call, cache Web services, low-frequency access large volume of data and SOAP message response compression methods.%通过对城市供水工艺流程以及在此过程中信息收集与管理业务的分析，设计并实现了一个基于物联网技术的供水信息系统。在系统开发中，针对无线网络频繁断接、高延迟、低可靠性等特点，采用Web服务技术架构了一个分层无线计算软件模型。并重点介绍了在无线环境中采用WSE确保Web服务安全以及通过异步调用Web服务、缓存Web服务、大数据量低频率访问和SOAP响应压缩等方法提高系统性能的实现方法。
