Embodiment 1

[0031] Such as figure 1 The tunnel digital twin system shown is characterized in that it includes five components including a physical entity module, a twin model module, a perception control module, a data management module, and a service application module.

[0032] The physical entity module is represented by the tunnel structure, facilities, rock masses around the tunnel, and the geographical and geological environment. It is the basic component module and the object of attention and operation of a tunnel digital twin system in the present invention. According to the construction process of the tunnel physical entity and the For specific functions in the operation phase, the physical entity of the tunnel is divided into surrounding rock, support, lining, pavement, pipeline and electromechanical equipment.

[0033] Such as figure 2 As shown, the twin model module is used to describe the characteristics of the geometry, physics, behavior, and rules of the physical entity m...

Embodiment 2

[0038] The construction of the twin model module should be the mapping and expression of physical entity information, which includes but not limited to planning and design information, geographical environment information of the tunnel site, geological survey information, and calculation and analysis theory of tunnel design.

[0039] The twin model module includes a three-dimensional information model, an analysis calculation model, and a behavior evolution model. For the tunnels in the operation phase and the construction phase, the construction of the twin model should highlight the different characteristics of the two life cycle stages.

[0040] For tunnels during the construction period, the 3D information model should accurately reflect the design intent. At the same time, the geographic and geological information in the 3D information model needs to be continuously supplemented and corrected during the construction period. The corresponding analysis calculation model and ...

Embodiment 3

[0046] like image 3 The perception control module shown is used for real-time monitoring and adjustment of the running status of facilities inside the tunnel, including perception equipment, transmission equipment, and control equipment. The perception control module collects the operating data of the physical entity of the tunnel in real time through the sensing device, uploads the operating data of the physical entity to the data management module through the transmission device, and the user calls and views the data through the service application module, so as to grasp the operating status of the physical entity of the tunnel in real time ; For the healthy and safe operation of the tunnel, when it is necessary to adjust the facilities in the tunnel, the user triggers the corresponding command in the service application module, and the transmission device of the perception control module transmits the command to the control device, thereby adjusting the operating state of t...

Abstract

The invention discloses a tunnel digital twinning system which comprises a physical entity module, a twinning model module, a sensing control module, a data management module and a service application module. The physical entity module is a real tunnel and surrounding rock mass thereof, the twin model module depicts and describes a physical entity from multiple dimensions, multiple spatial scales and multiple time scales, and the sensing control module is used for collecting and transmitting operation monitoring data, automatically regulating and controlling the operation state of part of equipment and controlling the operation state of the part of equipment. The data management module provides accurate, comprehensive and timely data management support for the tunnel digital twin system, and the service application module develops multiple functions for tunnel operation management; according to the invention, scheme guidance is provided for tunnel intelligent construction and operation maintenance.

Description

technical field [0001] The present invention relates to the technical field of construction, operation and maintenance of construction engineering, in particular to the field of construction and operation monitoring of tunnel engineering, in particular to application tools and implementation methods for tunnel intelligent construction and operation monitoring, specifically a digital twin system for tunnels. Background technique [0002] Cracks, bulges, water leakage and other diseases often appear in the tunnel during the operation and management stage. At present, the discovery of the above diseases mainly depends on the inspection personnel's naked eyes or the use of instruments and equipment for related detection (Chongqing Jiaotong University. A tunnel based on 5G technology Internal intelligent cloud control system: 202011400906.4[P].2021-04-06.), this method can only take remedial measures after the problem occurs, and often needs to be based on a large number of discre...
