The invention provides a construction site intelligent safety supervision 
system and a control method thereof. The 
system comprises 
a site access control device, a safety fence device, a device control terminal, a smart 
tower and a remote 
server, wherein the intelligent 
tower is used for realizing construction site panoramic view monitoring, construction on-site sound collection, 
odor collection,on-site lighting and voice broadcast and realizing sound-light alarm under abnormal circumstances, and the remote 
server is in communication connection with the intelligent 
tower, the safety supervision terminal and an intelligent reporting terminal through a 
mobile communication network and transmits corresponding data to a safety supervision management center through an 
Internet network. With the construction site intelligent safety supervision 
system and the control method thereof of the invention, the image information and environmental information of a construction site can be acquired inreal time; the unified control of construction workers and construction equipment can be realized; auxiliary lighting can be realized; alarm prompts can be given out when an abnormal condition occurs, and the abnormal condition is reported to the a
