Research and Monitoring of Metro Tunnel Deformation Based on Internet of Things

Abstract:

After a long subway tunnel operators will produce cross-sectional deformation. Articles designed vehicle laser ranging device for continuous measurement of tunnel wall to test their deformed state. The paper also describes the tunnel cross-section deformation measurement method, contour fitting principles and error analysis and networking technology for wireless data transmission methods. The detection system is designed to achieve a tunnel section of the structural safety testing and deformation that may occur timely disaster warning, the safe operation of the subway tunnel to provide effective protection.
