Application of Triggered Inclination Monitoring Microsystem Base on Double MEMS Accelerometers in Geological Disaster Monitoring
2022 International Conference on Artificial Intelligence in Everything (AIE)(2022)
Abstract
Aiming at the contradiction between precision, power consumption and real-time performance of the inclination monitoring microsystem, and according to the engineering characteristics of slow deformation and accelerated deformation of creep landslide, a triggered inclination monitoring microsystem based on double MEMS accelerometers is proposed in this paper. The system can use the high-precision MEMS accelerometer to monitor periodically, so as to realize the trend monitoring of geological disasters. It can also use the low-precision MEMS accelerometer to trigger monitoring, so as to achieve imminent early warning of geological disasters. The results show that the proposed microsystem has an accuracy of ±0.02° in the range of ±30°. The power consumption current of the periodic monitoring process is about 0.01mA. After the triggering monitoring process meets the threshold condition, the response time is less than 1s.
