A measurement unit module includes a printed circuit board (PCB) and electronic components being mounted on a front face of the PCB, a plurality of measurement unit modules are arranged at intervals in an extending direction of a stripped flat cable, the stripped flat cable is electrically connected to back faces of the plurality of PCBs in sequence to form a measurement unit cluster, the measurement unit cluster is packaged and molded by an extrusion technology of silica gel to form the flexible sensing strip, and the flexible sensing strip can be wound into a sensing strip reel. The packaging structure has the beneficial effects that connection integrity between the measurement unit modules is enhanced, connection strength is improved, and reliability of a flexible clinometer is improved. The flexible sensing strip can be wound into the sensing strip reel so as to be convenient to carry and convey.

Packaging structure of flexible sensing strip for monitoring large deformation at deep position of sliding mass and monitoring method

In an unmanned system for monitoring lateral deformation of a landslide based on inertial measurement, a deformable coupling pipeline is disposed in a landslide mass. An unmanned trajectory tracer is provided with a battery, a motor wheel, an inertial sensor, and a single chip microcomputer that are electrically connected. The single chip microcomputer controls the motor wheel to drive the unmanned trajectory tracer to move back and forth in the deformable coupling pipeline. The single chip microcomputer controls the inertial sensor to measure a shape of the deformable coupling pipeline. Two monitoring piers are disposed at two ends of the deformable coupling pipeline respectively. The monitoring pier is provided with a GPS device and a communication device, the communication device is in communication connection with the single chip microcomputer, and the single chip microcomputer obtains the shape of the deformable coupling pipeline and sends to the communication device.
