There are many technical application characteristics in the intelligent upgrading and transformation of large-scale existing stadiums. Based on the guidance of the national sports "14th Five-Year Plan" policy and the series of standards for smart sports stadiums

this paper sorts out the key points of intelligent improvement

and revitalizes the stadiums through the reuse and compatibility of existing facilities. Combined with the specific projects of the 15th National Games

it realizes the intelligent upgrading and low-carbon energy conservation of the stadiums by applying technologies such as AI

the Internet of Things (IoT) and 5G. Additionally

it summarizes the application of key technologies and implementation methods in the intelligent upgrading of the stadiums.
