基于ZigBee的自习室人数智能查询系统设计与实现

为方便高校学生利用网络或者智能手机终端设备实时查询自习教室现有人数,设计实现了一种基于ZigBee技术的自习室人数智能查询系统.系统根据物联网（IOT）层次模型开发,分为感知层、网络层、平台层和应用层四个层次.感知层采用红外光电开关作为数据采集传感器;网络层采用ZigBee技术构建无线传感网,实现多点人数数据统计;平台层使用SQL SERVER数据库和IIS信息服务器;应用层设计web查询管理网站与移动终端查询软件,能够进行自习室人数查询.

Design and Implementation of Self-Study Room People Number Intelligent Query System Based on Zigbee

In order to give an easy way to find proper self-study room for college students through web or smart phone terminal, this paper realized a self-study room people number intelligent query system based on ZigBee technology. System model is developed according to Internet of Things （lOT）, including Sensor, Network, Plat- form, Application four layers. Sensor layer adopts infrared photoelectric switch for data acquisition ; Network lay- er uses the ZigBee technology to build a wireless sensor network for multi point toll; Platform layer uses the SQL SERVER database and IIS information server; Application layer design web query management website and mo- bile terminal inquiry software, which can supply query number of people of self-study room.
