Smart engineering refers to the use of information means to carry out accurate design and construction simulation of engineering projects through the three-dimensional design platform, establish an interconnected, collaborative, intelligent production and scientific management information ecosystem of construction projects around the construction process management, and conduct data mining and analysis with the engineering information collected by the Internet of things in the virtual real environment, Provide process trend prediction and expert plan to realize visual and intelligent management of engineering construction, so as to improve the informatization level of engineering management, so as to gradually realize green construction and ecological construction.

Yunlian intelligent uses GIS technology and Internet of things (IOT) technology to restore the whole construction site as true as possible by combining the element status information of on-site equipment, personnel and environment management with 3D real map through intelligent devices such as mechanical housekeeper, oil tank cover, safety helmet, environmental monitor, intelligent gate and AI camera, So that construction managers can monitor the safety and efficiency of mechanical equipment and personnel in real time, grasp the overall construction progress, and master every project detail without running all day.

Intelligent engineering is a new concept of project life cycle management. It is based on the service mode of "Internet plus building big data", integrates cloud computing, big data and Internet of things, integrates relevant core resources, and conducts real-time monitoring of project management in a controllable, data visualization and visual intelligent system, and makes intelligent response according to actual situation. This is not only of great significance to safe and civilized construction, but also helps to promote the reform of construction methods, improve the scientific and technological innovation ability of the construction industry, how to strengthen the safety management of the construction site, reduce the frequency of accidents and effectively manage the impact of construction on the environment. The construction industry needs to keep pace with the times and seize the historical opportunity of the Internet era, Make use of existing mature technical resources and develop new intelligent systems to better serve the construction industry. Smart engineering is such a way to promote the quality and efficiency improvement of the construction industry and promote the transformation and upgrading of the construction industry.
