Construction process management and control method based on digital twinning

Abstract

The invention discloses a construction process management and control method based on digital twinning, which comprises the following steps: inputting an entity involved in a construction project into a virtual space, generating a digital twinning model in the virtual space, and forming a one-to-one mapping relationship between elements of the digital twinning model and elements of the entity; real-time data of the entity is collected and preprocessed, the real-time data comprises process data, resource data, equipment data and disturbance data, the preprocessed real-time data is used for replacing elements of the corresponding digital twinborn model, and a real-time digital twinborn model is obtained; the real-time digital twin model is simulated by using a big data analysis method, and a construction progress predicted value is output; and the current construction plan is optimized according to the construction progress predicted value, and an optimized construction plan is output. According to the method, the digital twinborn model is built, the actual construction process is synchronously executed, the digital twinborn model is updated in real time, the digital twinborn model predicts the construction process in advance, and then construction parameters are optimized.

Description

technical field [0001] The invention relates to the field of engineering management, in particular to a digital twin-based construction process control method. Background technique [0002] Construction progress is the lifeline of an enterprise. Due to the influence of multiple factors, the control of construction progress has always been a difficult problem. Sometimes the construction progress control is in place, but the cost increases a lot. Accurate, scientific and effective construction progress control is an urgent problem to be solved. [0003] The digital twin is a simulation technology that integrates multi-physical quantities, multi-scale, and multi-disciplinary attributes, and can realize the interaction and combination of the physical world and the information world. Digital twins are currently most widely used in the field of engineering construction in China. A mirror image of a physical entity is generated in space, and combined with real data to predict the f...

Problems solved by technology

Although digital twin technology has been widely applied in the field of engineering construction, the research on digital twin system for construction process control is still in its infancy. First, the existing construction period is estimated based on experience without adding other disturbance factors; second, it is difficult to Timely monitoring of disturbance factors that affect the construction period during the construction process, let alone eliminate the impact of the disturbance on the construction process in time
