Articles designed vehicle laser ranging device tbr continuous measurement of tunnel wall to test their defomaed state. The paper also describes the tunnel cross-section deltbrmation measurement method, contour titting 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.展开更多

This paper set up a wireless network (ZigBee protocol), sensor signal acquisition, wireless transmitting and receiving, serial communication software design of coordinator node and PC machine. Finally, we on-line debug each module of the system hardware and software. Experiments show that the network node data transmission accurate, reliable work, has basically met the design requirements.展开更多
