Aiming at the common problems in traditional construction sites

such as information fragmentation

delayed supervision and low collaboration efficiency

this paper

based on the scenario of electric power engineering projects

proposes a“1+4+N”concept by leveraging big data

IoT and Computer Vision.It designs the system architecture of smart construction site system

and clarifies the system’s functional modules and implementation paths.Through application in typical projects

the technical feasibility of the system in terms of construction site perception

analysis

control and management is verified.The results show that the system has improved the construction site’s capabilities in safety risk prevention and control

quality process supervision

and construction schedule management.It provides theoretical references and engineering practice examples for the construction and promotion of smart construction site system.
