摘要
为保障极寒天气条件下输电线路的安全运行,基于STM32微控制器研究了一种输电线路覆冰监测系统。采用高精度拉力、倾角传感器和微气象传感器采集数据,再将数据代入输电线路覆冰力学模型计算覆冰厚度,通过NB-IoT模块将覆冰厚度、拉力、倾角等9个参数上传至物联网云平台,用户可通过PC远程方式实时查询覆冰厚度等关键参数。为进一步降低输电线路覆冰监测系统的功耗,提出了一种间歇工作策略,分别测试了工作模式、低功耗模式和超低功耗模式下的系统功耗,实验结果表明,超低功耗模式下系统日均功耗为0.041 A·h,是工作模式日均功耗的9.47%,满足监测系统低功耗要求。
In order to ensure the safe operation of transmission lines under extremely cold weather,this paper designs a transmission line icing monitoring system based on STM32 microcontroller.The system uses high-precision tension,inclination sensors and micro-meteorological sensors to collect data,and puts data into the transmission line icing mechanical model to calculate the icing thickness.Then,9 parameters such as icing thickness,tension and inclination are uploaded to the Internet of Things cloud platform through NB-IoT module.Users can inquire in real time about key parameters such as icing thickness through PC remote mode.In order to further reduce power consumption of the transmission line icing monitoring system,the paper proposes an intermittent working strategy which tests the system power consumption of working mode,low power consumption mode and ultra-low power consumption mode respectively.According to the experimental results,average daily power consumption of ultra-low power consumption mode is 0.041 A•h which is 9.47%of that of the working mode,meeting the requirement of low-power consumption monitoring system.
