摘 要: 为解决ZigBee无线传感网系统中存在的传输距离短、信号弱、中继节点分布多和系统部署成本高等问题,设计了基于NB-IoT的无线通信系统。通过信息采集节点实时采集环境信息,然后通过NB-IoT网络将采集信息发送至基站,最终传输到云服务器,不同用户可以通过云服务器实现实时数据显示、数据查询等功能。与ZigBee通信方式相比,该系统具有无中继节点,部署灵活、传输距离长等特点。 In order to solve the problems of short transmission distance,weak signal,large number of relay nodes and expensive system deployment in the current ZigBee wireless sensor network system,a wireless communication system based on NB-IoT is designed.The system collects environmental information in real time through the information collection node,transmits the collected information to the base station through the NB-IoT network,and finally transmits to the cloud server.Different users can implement real-time data display and data query functions through the cloud server.Compared with the ZigBee communication method,it has the characteristics of no relay node,flexible deployment and long transmission distance.
