Visual solution of digital twin landing high-speed railway bridge

At present, informatization has risen to the national strategy , It is also the inevitable trend of the development of high-speed railway bridge construction . With the help of video twins （ Real time digital twins ） technology , Build a real-time three-dimensional scene of the high-speed railway bridge construction site , Build a three-dimensional carrier of intelligent bridge integrated management and control system . Combined with data mining and Analysis Technology , Improve the management efficiency of high-speed railway bridge construction , So as to realize the informatization upgrading of site management .

Beijing Zhihui Yunzhou Technology Co., Ltd. was established in 2012 year , Focused on Innovation “ Video twins （ Real time digital twins ）” Technology R & D and application . at present , Zhihui Yunzhou relies on self-study “ Twin boat ” Digital twin exclusive engine , Launched “ pizza ” Low code PaaS Video twin development platform 、“ Instant coffee ” Video twin all-in-one machine and video twin industry solutions and other product lines .

With the leading technological foundation , Zhihui Yunzhou continues to help transform transportation digitalization , And promote the digital upgrading of industrial cooperation . The company has successively participated in the construction of many key projects , The application field involves smart cities 、 Wisdom park 、 Digital village 、 Industrial manufacturing 、 Rail transit 、 military 、 Snow project （ Safe city ）、 Judicial supervision 、 Emergency command 、 School 、 The hospital 、 Water conservancy 、 Power and other industry wide scenarios .

At present, the subsystems of the information management system of high-speed railway bridge construction site are isolated , Information “ Isolated island ” The phenomenon is serious , Lack of a unified and visual platform for centralized control of project information . Through the exploration and application of digital twin Technology , Combined with the actual needs of the construction site , Create a site twin based on digital twins , Realize real-time control on the construction site . Specific realizable applications include ：

1、 Intelligent video monitoring system

Video monitoring as an effective supplement to construction monitoring , Send back via video , It is helpful for engineering and technical personnel to know the progress and construction status of the construction site in time , Through intelligent identification technology, it can intelligently alarm the potential safety hazards on site , Further ensure the safety and quality of on-site construction .

2、 Intelligent management and control system for bridge monitoring

During the construction, the stress of the embedded bridge at the key position of the long-span high-speed railway bridge 、 Temperature monitoring sensor , Use data acquisition equipment to obtain sensor data , Then upload to the server through the network , And with BIM Model for Data Association Real time display of monitoring information , If the value exceeds the limit, it will give a real-time alarm , Finally, the real-time monitoring of the bridge safety status in the construction process is realized , At the same time, it provides data support for the later stress analysis of the bridge .

3、 be based on “ A picture ” Realize multi-level management

Through the high-precision three-dimensional model of high-speed railway bridge , Combining digital twins and three-dimensional geographic information technology , Unified management of all site projects , Carry out hierarchical loading management according to information and authority , Build on “ A picture ” Multi level project management . It is divided into : Company level control 、 Project level control 、 Production task level monitoring .

(1) Company level control

The company level control function will control the overall macro production progress of the company 、 output value 、 Sort out and count the safety warning information , Make a visual presentation .

(2) Project level control

The project level control function controls specific projects , Including the weather conditions at the project site, production output value, raw material consumption 、 Personnel distribution 、 Sensor safety monitoring and on-site video real-time monitoring and other functions .

(3) Production task level monitoring

This function is mainly to strengthen the process of the construction site 、 speed of progress 、 Quality and other multi-dimensional real-time management , From the basic information 、 Construction process project management 、 Sensor monitoring, etc 4 Three aspects of management . Through the basic information module, the bridge digital simulation and information structure tree management , Combined with the construction technology of different processes of the bridge , Realize three-dimensional construction technology training and disclosure . The project management module automatically associates the progress and inspection information of the project , Real time correlation of construction progress information of the project , Combined with 3D BIM Model , Visual monitoring and early warning of progress . The construction monitoring module correlates the bridge strain through integration 、 Displacement 、 Temperature and other monitoring sensor data , Upload to the smart site system based on the network , Three dimensional display of measured data , And sort out the data 、 Statistical analysis , Realize the safety and quality management during the construction of long-span high-speed railway bridges .
