摘要
针对特殊商品的监管问题,介绍一种基于物联网技术的环境情景感知系统解决方案,叙述情景感知网关的开发过程。该网关硬件以嵌入式ARM处理器为核心,实现多信源感知以及环境情景信息的处理与传输。软件采用Linux操作系统,配合数字降噪、非线性补偿、参数映射等技术,获得高精度的感知数据。经应用证明,该系统不仅可完成分布式多信源环境情景的监测,还能通过对数据的深度挖掘,实现多种智能服务。
For the supervision of special goods, the solution is introduced for the environment context aware system based on Internet of Things（loT） technology. It specifically focuses on the design process of the context awareness gateway. The hardware of the gateway is based on ARM11 processor, which can perceive on the muiti-source, process and transmit environmental context information. The software of the gateway uses Linux operating system. The design can obtain high-precision sensing data by using digital filtering techniques, noolinear compensation technology and parameter mapping technology. The application verifies that the system not only can monitor the distributed multi-source environment context, but also can realize intelligent service through data mining deeply.
