Smart construction sites refer to the use of information technology to accurately design and construct construction simulations of engineering projects through a three-dimensional design platform, and around construction process management to establish an information ecosystem of interconnected collaboration, intelligent production, and scientific management of construction projects, and to use this data in Under the virtual reality environment and the Internet of Things, we conduct data mining and analysis on the engineering information collected, provide process trend predictions and expert plans, and realize visual intelligent management of engineering construction to improve the informatization level of engineering management, thereby gradually realizing green construction and ecological construction.
Smart construction sites implant more high-tech technologies such as artificial intelligence, sensing technology, and virtual reality into various objects such as buildings, machinery, personnel wearable facilities, and site entry and exit gates, and are widely interconnected to form the "Internet of Things". Integrate with the "Internet" to realize the integration of project management stakeholders and project construction sites. The core of the smart construction site is to use a "smarter" method to improve the way in which relevant organizations and personnel in the project interact with each other, so as to improve the clarity, efficiency, flexibility and response speed of interactions.

2. The significance of smart construction site construction
Wisdom can determine and change the quality of a city; smart cities determine and enhance the future city status and development level. As an advanced stage of urbanization, smart cities are characterized by the integration of large systems, interaction between physical space and cyberspace, and multi-party public participation and interaction to achieve urban innovation, thereby making urban management more refined, the urban environment more harmonious, and the urban economy more high-end. , city life is more livable.
The construction industry is a high-risk industry with many safety accidents. How to strengthen construction site safety management, reduce the frequency of accidents, eliminate various illegal operations and uncivilized construction, and improve the quality of construction projects is an important research topic for people in the industry and scholars.
In this context, with the continuous development of technology, the application of information technology, mobile technology, smart wearables and tools in the engineering construction stage has been continuously improved, and smart construction site construction has emerged as the times require.
The construction of smart construction sites is of great significance in realizing green construction, leading the application of information technology, and improving the comprehensive competitiveness of society.
3. Smart construction site technical support
Data exchange standard technology, in order to realize smart construction sites, it is necessary to exchange information and data between different project members and different software products. Because this information exchange involves a wide variety of project members, complex project stages and project life cycles With a long time span and a large number of application software products, only by establishing an open information exchange standard can all software products exchange information with each other through this open standard, and information between different project members and different application software can be realized. Flow, this object-based open information exchange standard format includes three standards: defining the format of information exchange, defining the exchange information, and ensuring that the exchanged information and the required information are the same thing.
BIM technology
BIM technology can effectively perform operation and maintenance management during the service life of the building. BIM technology has the ability to spatially locate and record data. When applied to the operation and maintenance management system, construction equipment components can be quickly and accurately positioned. Conduct accessibility analysis of materials, select sustainable materials, perform preventive maintenance, and develop effective maintenance plans. The combination of BIM and RFID technology can import building information into the asset management system, which can effectively manage the assets of the building. BIM can also perform space management and use building space rationally and efficiently.
Visualization technology
Visualization technology can turn scientific data, including measured values, images collected on site, or digital information involved and generated in calculations, into intuitive, graphic and image information representations of physical phenomena or physical quantities that change over time and space. In front of managers, enabling them to observe, simulate and calculate. This technology is the prerequisite for smart construction sites to achieve three-dimensional display.
3S technology
3S technology is the collective name for remote sensing technology (Remotesensing, RS), geographic information systems (Geography information systems, GIS) and global positioning systems (Global positioning systems, GPS). It is a combination of space technology, sensor technology, satellite positioning and navigation technology, computer technology, and communication technology. Combining modern information technology with multi-disciplinary and highly integrated collection, processing, management, analysis, expression, dissemination and application of spatial information, it is a centralized display platform for smart construction site results.
virtual reality technology
Virtual Reality (VR) is a technology that uses computers to generate a simulated environment and "immerse" users into the environment through a variety of sensing devices, allowing users to directly interact naturally with the environment. It allows designers who apply BIM to interact with computer-generated environments in a natural way with an immersive feeling, and experience a richer experience than the real world.
Digital construction system
Digital construction system refers to the integration of construction site information resources and breakthroughs in time and space by relying on the establishment of basic platforms such as digital geographical basic platform, geographical information system, remote sensing technology, construction site data collection system, construction site mechanical guidance and control system, and global positioning system. limitations, and establish an open information environment to enable various participants in engineering construction projects to exchange real-time information more effectively and use BIM model results for digital construction management.
Internet of Things (IOT)
The Internet of Things is an important part of the new generation of information technology, and its English name is: "The Internet of things". As the name suggests, the Internet of Things is the Internet where things are connected. This has two meanings: First, the core and foundation of the Internet of Things is still the Internet, which is an extension and expansion of the Internet based on the Internet; second, its user end extends and expands to any item to carry out information. exchange and communication. The Internet of Things is the “Internet of connected things.” The Internet of Things is widely used in the integration of networks through intelligent sensing, identification technology and ubiquitous computing. It is therefore known as the third wave of the development of the world's information industry after computers and the Internet.
cloud computing technology
Cloud computing is the product of the integration of computer technology and network technology such as grid computing, distributed computing, parallel computing, utility computing, network storage, virtualization and load balancing. It aims to integrate multiple relatively low-cost computing entities into a perfect system with powerful computing capabilities through the network, and distribute these powerful computing capabilities to end users. It is the best technical means to solve the transmission and processing of BIM big data.
Information management platform technology
The main purpose of information management platform technology is to integrate existing management information systems and make full use of data in BIM models for management interaction, so that all participants in project construction can work together on a unified platform.
Database technology and the application of BIM technology will rely on database technology that can support big data processing, including massive parallel processing (MPP) databases, data mining power grids, distributed file systems, distributed databases, cloud computing platforms, and the Internet. , and scalable storage systems.
Network communication technology
Network communication technology is the communication bridge for BIM technology applications and the channel for BIM data circulation, forming the basic network of the entire BIM application system. According to the actual project construction conditions, mobile phone networks, wireless WIFI networks, radio communications and other solutions can be used to meet the communication needs of project construction.
