Shield tunneling machine three-dimensional virtual simulation system and simulation method

Abstract

The invention discloses a shield tunneling machine three-dimensional virtual simulation system and a simulation method and mainly aims at solving the problems that a motion process of the shield tunneling machine can not be simulated in real time and roaming in the shield tunneling machine can not be realized in the prior art. According to the technical scheme, the simulation method comprises the following steps: firstly, constructing a shield tunneling machine three-dimensional model and optimizing; secondly, acquiring real-time working condition data of the shield tunneling machine by a sensor and transmitting to a data server; thirdly, acquiring data of the data server by a system server and carrying out data transformation, and transforming real-time working condition data of shield construction into data for driving the shield tunneling machine three-dimensional model to move; and fourthly, importing the shield tunneling machine three-dimensional model and the data for driving the shield tunneling machine three-dimensional model to move into a simulation environment to realize three-dimensional simulation of a shield tunneling machine construction process, historical playback of the shield tunneling machine construction process, roaming of a working scene of the shield tunneling machine and monitoring of a shield tunneling machine construction state, so that an operator knows the working principle and the actual working condition of the shield tunneling machine more directly and clearly. The simulation system and the simulation method which are disclosed by the invention can be applied to teaching and training of the working principle of the shield tunneling machine.

Description

technical field [0001] The invention belongs to the technical field of simulation, and in particular relates to a three-dimensional virtual simulation system of a shield machine, which can be used for simulating and monitoring the construction process of the shield machine in tunnel engineering. Background technique [0002] With the continuous development of national infrastructure, there are more and more tunnel projects, and shield construction is gradually promoted in the railway industry, such as Shiziyang Tunnel, Beijing Diameter Line, Zhongtianshan Tunnel, Changzhou-Zhuzhou-Tanshan, Pearl River Delta and other intercity railway tunnels The construction shall adopt the shield tunneling method. According to statistics, there are currently more than 30 cities in my country that are conducting preliminary planning, design, preparation and construction of rail transit. In the next 10 years, more than 5,000 kilometers of various shield tunnels will be built, so shield mach...

Problems solved by technology

[0006] The existing 3D virtual simulation system of shield machine, such as "Research on Web-based Subway Shield Tunnel Construction Monitoring System" originated from "National Engineering Safety and Protection Academic Conference, 2012", the system is based on Flex and Java platform, although the system realizes The 3D geological modeling based on the B / S mode enables real-time viewing of project progress, geological parameters, and shield parameters, as well as profile analysis and historical data analysis, and monitoring of shield machine and 3D geological information data. However, the three-dimensional visual monitoring of the shield machine has not been realized, the movement process of the shield machine cannot be simulated in real time, and the roaming and alarm functions in the shield machine cannot be realized.
