Design of Monitoring System for the Measurement of Surrounding Rock Deformation in Underground Tunnels [PDF]
2017 International Conference on Computer Technology, Electronics and Communication (ICCTEC), 2017 This study designs an automatic monitoring system for non-contact measurement of the surround rock deformation in underground tunnels in an unattended operation mode. This system can automatically and periodically monitor the deformation of the surrounding rocks in underground tunnels with low power consumption, and write the monitored deformation data
