The application relates to an intelligent isolation bearing online
monitoring system, an installation process and a monitoring method. The
system integrates force value,
angular acceleration and displacement monitoring functions on the basis of an isolation bearing, is composed of an upper sealing plate, a rubber body, a lower sealing plate and a
monitoring system, is used for simultaneously monitoring vertical loads transmitted from an upper building to a lower foundation and
angular acceleration and horizontal displacement of the isolation bearing, and is composed of a ring-shaped
pressure sensor, an
inertial measurement unit (IMU), a displacement sensor, a
data acquisition and transmission module, a
cloud server and a monitoring platform. The
system adopts a full-sensor external
modular structure, is matched with a six-order Kalman fusion
algorithm, a multi-parameter
coupling early warning criterion, an IMU dynamic drift calibration model, and a special pre-tightening and anti-loosening installation process, is suitable for various working conditions, realizes synchronous acquisition of multi-dimensional parameters of a bearing,
data noise reduction fusion and
fault grading early warning, and can realize real-time monitoring of stress,
angular acceleration and displacement states of a building isolation bearing.
