摘要
针对具有标准协议输出的电梯物联网监测特点,设计了基于NB-IoT的电梯物联网智能监测终端。它采用ME3616型NB-IoT模组和STM32L432处理器,通过串行接口采集电梯运行信息,实现电梯运行状态的实时监测、困人报警和故障预警等功能。
According to the characteristics of elevator IoT monitoring with standard protocol output,an intelligent monitoring terminal of elevator IoT based on NB IoT is designed.Application of ME3616 NB IoT module and STM32l432 processor to collect elevator operation information through serial interface,so as the functions of real-time monitoring of elevator operation status,trapped alarm and fault warning are realized.
