Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The shield tunnel intelligent monitoring system based on VR simulation technology includes:

[0028] Distributed optical fiber displacement sensor: arranged in the middle of the shield tunnel along the circular direction of the segment, see figure 1 , which is used to monitor the deformation of each segment of the shield tunnel ring, so as to detect the convergence deformation value of the shield tunnel structure. The distributed optical fiber displacement sensor is composed of bare fiber, cladding, coating layer and sheath structure. Its main advantage is that it can realize a large-capacity distributed layout, and the optical fiber in one layout can reach several kilometers. The main component of the core and the cladding is silica, the diameter of the bare fiber is about 8-10 μm, and the diameter of the cladding is about 100-200 μm...

Abstract

The invention relates to a shield tunnel intelligent monitoring system based on a VR simulation technology. The system is characterized by comprising a distributed optical fiber displacement sensor, adistributed optical fiber temperature sensor, a fiber grating displacement sensor, and a VR simulation device. The system comprises a data analysis unit and a VR virtual display unit which are connected with each other. The data analysis unit is connected with the distributed optical fiber displacement sensor. The distributed optical fiber temperature sensor is wirelessly connected with the optical fiber grating displacement sensor. The data analysis unit is used for calculating the structural internal force data of the shield tunnel in real time, and the VR virtual display unit is used for drawing a structural disease effect picture of the shield tunnel according to the structural internal force data obtained by the data analysis unit and displaying the structural disease effect pictureto a user in a VR form. Compared with the prior art, the method has the advantages that monitoring feedback is fast, the display effect is vivid, and application is not limited by the operation range.

Description

technical field [0001] The invention relates to a safety state monitoring technology in the traffic field, in particular to a shield tunnel intelligent monitoring system based on VR simulation technology. Background technique [0002] With the vigorous development of urban subways, the shield tunneling method has been widely used in the construction of subway tunnels as a safe, environmentally friendly and rapid construction method. However, during the construction and operation phase, the existing subway shield tunnel structure will be affected by factors such as the close construction of new buildings, vehicle vibration, diffuse current, and erosive media. Defects of different degrees, such as opening and misalignment, also began to appear frequently. Therefore, monitoring the structural safety status of the shield tunnel is an important prerequisite for ensuring the normal operation of the subway. [0003] Due to the many types of structural diseases of the shield tunnel...
