Research and design of wireless sensor network gateway based on ZigBee

为了更好地实现传感器节点数据的采集和监测,提出了一种基于ZigBee的无线传感网络网关的设计方案。该网关系统以ARM Cortex-A8为主控模块,外接WiFi模块和ZigBee协调器,采用ZigBee协议建立无线传感器网络,而且通过WiFi模块接入互联网,实现对传感器节点数据的采集。实验结果表明,基于ZigBee的无线传感网络网关,使用简单,可以快速地实现对外部环境数据的采集,可扩展性强,可以广泛应用于消防楼宇监测、农业灌溉、机床设备监测等各个领域。

In order to better implement the sensor node data acquisition and monitoring , this paper puts forward a design scheme based on ZigBee wireless sensor network gateway. The gateway system based on ARM Cortex-A8 as master control module, and is connected with WiFi module and ZigBee coordinator. The ZigBee protocol is adopted to establish the wireless sensor network , and access to the Internet through WiFi module, realized the data collection of sensor nodes. The experimental results show that the wireless sensor network gateway based on ZigBee is easy to use and can quickly realize external environmental data collection. With the good extensibility , this system can be widely used in building , agriculture, machine tool and other fields.
