Scientific monitoring is an important technical prerequisite for achieving early warning and active prevention of geological disasters. Combining international advanced experience and technological progress, the "three checks" system is composed of high-precision optical remote sensing+InSAR "census", airborne LiDAR+drone aerial photography "detailed investigation", ground investigation verification+monitoring "verification". Geological disaster monitoring has gradually developed from traditional point based manual monitoring to "sky air ground" multi-dimensional collaborative monitoring, and has gradually become the main direction of geological disaster risk identification and monitoring early warning development.
The MEMS IMU+GNSS combination monitoring system can achieve realtime dynamic transmission of core data for earthquake disaster monitoring, such as deformation acceleration, horizontal displacement, and inclination angle. The 24_hour real_time working feature greatly improves the timeliness of monitoring and has the ability to monitor and warn in advance, making disasters no longer sudden.
In geological hazard monitoring, inertial sensors can be used to measure parameters such as acceleration, angular velocity, and azimuth of disaster events such as earthquakes, landslides, and ground collapses. Specifically, acceleration refers to the speed at which an object's velocity changes and can be used to determine the intensity of an earthquake; Angular velocity refers to the speed at which an object rotates, which can be used to determine the direction and velocity of landslides or ground subsidence; Azimuth angle represents the direction of an object in three_dimensional space and can be used to help locate the location of a disaster. The measurement of these parameters can provide real_time feedback and early warning information in the event of disasters, which helps to take emergency measures in a timely manner and protect the safety of people's lives and property.
Safety engineering refers to a comprehensive engineering project that involves the safe design, management, and operation of buildings, engineering structures, equipment, systems, etc. through scientific and technological means. In buildings, inertial sensors can be used to monitor vibration and deformation, which can timely detect changes in the building and ensure its stability and safety. Inertial sensor is a type of sensor that determines the state and motion of an object by measuring its inertial force. It can detect changes in building movement, vibration, rotation, etc. Based on the detection results, it can be processed in a timely manner to predict and prevent building collapse and other safety accidents, ensuring personal and property safety. Therefore, inertial sensors play an important role in safety engineering, which can effectively improve the safety performance and service life of buildings.
