        摘 要:為保障極寒天氣條件下輸電線路的安全運(yùn)行,基于 STM32 微控制器研究了一種輸電線路覆冰監(jiān)測系統(tǒng)。采用高精度拉力、傾角傳感器和微氣象傳感器采集數(shù)據(jù),再將數(shù)據(jù)代入輸電線路覆冰力學(xué)模型計(jì)算覆冰厚度,通過 NB-IoT 模塊將覆冰厚度、拉力、傾角等 9 個(gè)參數(shù)上傳至物聯(lián)網(wǎng)云平臺(tái),用戶可通過 PC 遠(yuǎn)程方式實(shí)時(shí)查詢覆冰厚度等關(guān)鍵參數(shù)。為進(jìn)一步降低輸電線路覆冰監(jiān)測系統(tǒng)的功耗,提出了一種間歇工作策略,分別測試了工作模式、低功耗模式和超低功耗模式下的系統(tǒng)功耗,實(shí)驗(yàn)結(jié)果表明,超低功耗模式下系統(tǒng)日均功耗為0.041 A•h,是工作模式日均功耗的9.47%,滿足監(jiān)測系統(tǒng)低功耗要求。

        Abstract: 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.
        Key words: STM32 microcontroller; icing monitoring system; transmission line; low power consumption; NB-IoT module
