Abstract
A lidar-based convergence deformation monitoring system for surrounding rock around a TBM shield region, including a data acquisition module. The data acquisition module includes: a lidar, a push-rod motor, an H-bridge circuit, a power supply module, an ARM chip, a guide rod, a linear bearing, a tempered glass cover and a protective case. The lidar and the push-rod motor are connected to a lidar connector to acquire raw data of the surrounding rock and store the raw data in the ARM chip. A middle portion of a top plate of the protective case allows the lidar to extend out of the protective case. The protective case is fastened to an inner wall of the TBM shield through two mounting brackets on both sides of the protective case, and the inner wall facilitates the lidar to extend out of the protective case to perform a measurement.
