基于物联网的疫苗冷藏箱温度监控系统的设计

Design of Vaccine Refrigerator Temperature Monitoring System Based on Internet of Things

目的为满足疫苗运输在最后一公里的信息可视化和透明化的需求,研究一款信息型智能包装的远程温度监控系统。方法通过结合物联网技术,设计一款基于GD32F330C8T6芯片为核心的子机节点与主机LoRa网关,以及基于Qt Creator 5.12软件和SQLite数据库编写的上位机软件,最终实现具体实例——远程温度监控系统,将子机节点硬件嵌入疫苗冷藏箱中,以及把多点测温探头置于箱内不同位置上,实现对疫苗冷藏箱温度的区间监控。结论通过该温度远程监控系统,用户可以实时监测运输车内不同冷藏箱内的温度情况,超温时系统可自动闭合主机继电器模块开启外部制冷器,实现了疫苗冷藏箱智能包装。

The work aims to develop a remote temperature monitoring system for information-based intelligent pack-aging to meet the needs of information visualization and transparency in the last kilometer of vaccine transportation.By combining the Internet of Things technology,a LoRa gateway between the sub computer node and the host comput-er based on the GD32F330C8T6 chip as the core,and the upper computer software based on the Qt Creator 5.12 software and SQLite database were designed.Finally,a specific example of remote temperature monitoring system was realized,and the hardware of the sub computer node was embedded in the vaccine refrigerator.The multi point temperature mea-suring probes were placed at different positions in the refrigerator to monitor the temperature range in the vaccine refri-gerator.Through the remote temperature monitoring system,users can monitor the temperature of different refrigerators in the transport vehicle in real time.The overtemperature system can automatically close the host relay module to open the external cooler,realizing the intelligent packaging of vaccine refrigerators.
