摘　　要：针对传统崩塌监测设备实时性、功耗和精度相矛盾的问题,文章采用基于STM32和高低精度传感器相结合的方法,实现高实时性、超低功耗、高精度的崩塌灾害监测,将崩塌灾害监测分为临灾预警和趋势监测。利用低精度传感器触发模式,设备以超低功耗工作状态实现崩塌监测临灾预警功能;利用高精度传感器触发模式,设备以周期性数据采集工作状态实现崩塌趋势监测功能。试验表明,高低精度双加速度计崩塌监测传感器,超低功耗状态可达13μA,唤醒状态可达31.92μA,临灾预警可在1 s内将预警命令发出,趋势监测倾斜角度可达0.1%FS。In response to the contradiction between real-time performance,power consumption,and accuracy of traditional landslide monitoring equipment,the article adopts a method based on STM32 and high and low precision sensors to achieve high real-time,ultra-low power consumption,and high-precision landslide disaster monitoring.The monitoring of landslide disasters is divided into emergency warning and trend monitoring.By using low precision sensor triggering mode,the device achieves collapse monitoring and disaster warning function in an ultra-low power consumption working state.By utilizing high-precision sensors,the equipment achieves the monitoring of collapse trends through periodic data collection of working status.Experiments have shown that the high-precision dual accelerometer collapse monitoring sensor can achieve an ultra-low power consumption state of 13μA and a wake-up state of 31.92μA.The disaster warning command can be issued within 1 s,and the trend monitoring tilt angle can reach 0.1%FS.
