基于NB-IoT及ZigBee的无线传感器网络网关设计
|
摘要
为了使ZigBee网络数据能够通过无线方式直达远程控制中心,设计了基于NB-IoT及ZigBee的无线传感器网络网关。网关由ZigBee芯片CC2530和NB-IoT模块BC95组成,两者通过串口相连。ZigBee协调器是ZigBee网络的控制中心,收集各个节点的数据,并通过串口将数据发送给BC-95模块。BC-95模块通过NB-IoT网络将数据传输到云平台或者控制中心,云平台或者控制中心的指令通过NB-IoT网络到达ZigBee协调器,协调器再将指令转发到下属节点。实验表明,系统运行稳定,适用于无线传感器网络的诸多应用场合。
In order to enable ZigBee network data to reach the remote control center wirelessly, a wireless sensor network gateway based on NB-IoT and ZigBee is designed. The gateway consists of a ZigBee chip CC2530 and a NB-IoT module BC95, which are connected through a serial port. The ZigBee Coordinator, as the control center of ZigBee network, collects data from each node and sends the data to the BC-95 module through the serial port. The BC-95 module transmits data to the cloud platform or control center via the NB-IoT network. The commands of cloud platform or control center arrive at the ZigBee coordinator through the NB-IoT network, and then the coordinator forwards the commands to the subordinate nodes. Experiments indicate that the system is stable and suitable for many applications in wireless sensor networks.
