基于NB-IoT技术的远程粮情监控系统设计

作为世界上的人口大国,粮食产量一直是我国关心的主要问题。为了解决粮食的安全存储问题和传统仓储环境监测系统灵活性差、功耗高的问题。该文设计了一种基于NBIoT技术的低功耗粮情环境远程监控系统。以STM32L476作为微控制器、BC35-G作为无线通信单元,对粮仓环境监控系统进行了软、硬件设计,使该系统具备实时采集和存储多传感器节点信息(如温度、湿度、烟雾浓度等)、无线传感器网络对数据分组转发、智能终端实时显示和远程控制,解决了以往监控系统的局限性。通过实地测试和反馈,该系统具有低功耗、可靠性高、灵活性强等特点,可实现对粮仓环境参数的实时监测与控制,能够较好地满足应用需求。

Design of Remote Grain Monitoring System Based on NB-IoT Technology

As a populous country in the world,food production has always been a major concern for our country. In order to solve the problem of safe storage of food and the poor flexibility and high power consumption of the traditional storage environment monitoring system. A low-power food environment remote monitoring system based on NBIoT technology was designed. Using STM32 L476 as the microcontroller and BC35-G as the wireless communication unit,the software and hardware design of the granary environmental monitoring system is implemented,so that the system can collect and store multi-sensor node information(such as temperature,humidity,smoke concentration,etc.) in real time. The wireless sensor network solves the limitations of the previous monitoring system by data packet forwarding,real-time display of intelligent terminals and remote control. Through field testing and feedback,the system has the characteristics of low power consumption,high reliability and flexibility,which can realize real-time monitoring and control of the environmental parameters of the granary,which can better meet the application requirements.
