TECHNICAL FIELD

[0001] The application belongs to the technical field of bridge construction monitoring, and particularly relates to a bridge construction safety monitoring control device based on digital twinning and a use method thereof. BACKGROUND

[0002] The highway bridge construction in China is developing at an unprecedented scale. Concrete bridges appeared in the 1930s, and have been developing rapidly since the 1950s. Bridges have broad application prospects due to their large span, light weight, high bearing capacity, economic and reasonable design, and less investment in temporary facilities.

[0003] In recent years, with the rapid development of China's economy, technology and equipment manufacturing industry, the industrialization level of bridge construction in China has been greatly improved. In the traditional bridge construction industry, human factors account for a large proportion of the quality. How to monitor and control the bridge construction during the bridge construction process and timely adjust the construction plan has become a problem.

[0004] Digital twinning is a simulation process that fully utilizes physical models, sensor updates, operation history and other data, integrates multi-disciplinary, multi-physical, multi-scale and multi-probability, and completes mapping in a virtual space, thereby reflecting the whole life cycle process of the corresponding entity equipment.

[0005] With the maturity of the concept of digital twinning and the development of technology, a digital twinning world is being continuously built from components to complete machines, from products to production lines, from production to services, and from static to dynamic. Digital twinning transfers entity data to virtual space in real time, provides a virtual foundation for realizing digital, intelligent and networked industrial models, and provides a more clear exploration path for human future imagination. Digital twinning technology is also widely applied to bridge construction.

[0006] The patent application with the publication number CN117387559B provides a concrete bridge monitoring system and method based on digital twinning. The system updates the model in real time by collecting the bridge structure parameters of each detection node on the concrete bridge in real time, and collects the site monitoring parameters to monitor the deformation of the concrete bridge. Simulation models are respectively established and linked to the digital twinning model. The information interaction function of the digital twinning model is used to better and timely correct the simulation model according to the feedback deformation data, and realizes the function of artificial intelligence assisted safety prediction, which provides quality guarantee for construction. The application links the bridge informatization model to digital twinning, simulates the influence effect of internal force of the bridge through the algorithm prediction model, and the digital twinning model gives real-time feedback and regulation and control to the whole construction process, improves the information utilization rate in construction operation, and to a certain extent, guarantees the engineering quality and provides convenience for bridge construction control.

[0007] The patent application with the publication number CN114925562A provides a prefabricated bridge digital twin system and method, including five types of modules: physical entity module, digital twin, perception control module, data management module, and application service module. This technology is aimed at the full assembly of piers, beams, foundations, crash walls, and wet joints, supports, and bridge deck pavement. It establishes component-level, part-level, and system-level digital twins from the factory to the site assembly. It monitors the construction process based on Internet of Things technology and transmits the monitoring results to the digital twin in real time to obtain the digital twin system of the physical entity. Based on this, it makes predictions and scientific decisions for the prefabricated bridge construction process. The invention provides a scheme guide for the intelligent construction of prefabricated bridges.

[0008] The patent application with the publication number CN202582472U provides a prestressed concrete box girder shrinkage and creep self-identification monitoring system. It includes a data measurement unit for measuring the shrinkage strain of the prestressed concrete box girder, the strain of the prestressed concrete, and the temperature value of the measurement point. A data acquisition unit is used to collect the data measured by the data measurement unit and transmit it to the data control and creep identification unit. The data control and creep identification unit processes the data collected by the data acquisition unit, automatically separates the shrinkage and creep strain increment of the concrete, and gives the creep strain value accordingly. By processing the variable data measured by the data measurement unit collected by the data acquisition unit, the creep strain value of the concrete over time is obtained, and the development law of the measured shrinkage and creep strain of the bridge superstructure concrete is given, realizing accurate prediction of the long-term creep deformation of the long-span prestressed concrete box girder bridge.
