摘　　要：针对农产品冷链物流中存在的运力不足和无法混装小批量冷链农产品等问题,提出一种基于NB-IoT技术的智能保温箱解决方案。该方案基于半导体制冷片、PT100温度传感器和NB-IoT技术构建了系统的硬件部分,实现了远程温控和冷链物流追溯,同时利用串级模糊PID算法实现了全程精确控温。此外,基于Simulink搭建了智能保温箱温度控制系统模型,通过仿真对比验证了智能保温箱的温度控制效果。结果显示,与PID算法和模糊PID算法相比,保温箱应用的串级模糊PID算法具有更快的调节速度和更小的超调量,并在受到干扰时表现出更好的稳定性,为农产品冷链物流领域提供了高效可靠的温度控制方案。In allusion to the problems of insufficient capacity and the inability to mix and load small quantities of cold-chain agricultural products in cold-chain logistics of agricultural products,an intelligent incubator solution based on NB-IoT(narrow band Internet of Things)technology is proposed.In the solution,the hardware part of the system is built based on semiconductor refrigeration chip,PT100 temperature sensor and NB-IoT technology,which can realize the remote temperature control and cold chain logistics traceability.Meanwhile,the cascade fuzzy PID algorithm is used to realize the whole accurate temperature control.In addition,the temperature control system model of the intelligent incubator is constructed based on Simulink,and the temperature control effect of the intelligent incubator is verified by the simulation comparison.The results show that,in comparison with the PID algorithm and fuzzy PID algorithm,the cascade fuzzy PID algorithm applied to the incubator has faster regulation speed and smaller overshooting amount,and can show better stability when disturbed,which provides an efficient and reliable temperature control program for the field of cold chain logistics of agricultural products.
