摘要/Abstract

摘要：

针对传统环境监测系统功耗高、维护成本高、不能实时监测的弊端，研制了一种以单片机为主控制芯片的基于 NB-IoT 技术的环境温湿度监测系统，并对主控制器的工作流程及通信模块的工作方式进行优化，降低系统功耗。利用NB-IoT通信技术进行数据传输，将温湿度传感器采集的数据信息通过基站和核心网发送给云平台，运用中国移动物联网开放平台（OneNET平台）实现终端设备与应用的相互连接。通过平台的拓展功能实现网页界面及手机应用程序的设计，最终实现对环境参数的远程实时监测，提高使用便捷度。

Abstract:

In view of the disadvantages of the traditional environmental monitoring system, such as high power consumption, high maintenance cost and no real-time monitoring, an environmental temperature and humidity monitoring system based on narrow band Internet of things (NB-IoT) technology was developed, which is mainly controlled by singlechip microcomputer.The work flow of the main controller and the working mode of the communication module were optimized to reduce the power consumption of the system.NB-IoT communication technology was utilized for data transmission to the cloud platform through the base station and core network.China Mobile IoT open platform (OneNET platform) was adopted to achieve the connection between the terminal device and the application, and expanded functions provided by the platform was used to design a mobile phone application to achieve the remote real-time monitoring of environmental parameters and improve the user’s convenience.

Key words: environmental monitoring, NB-IoT technology, OneNET, low power consumption, system design
