The intelligent construction site management system according to claim 1, characterized in that: The specific judgment process of judging whether the tower crane operator's corresponding working status is serious is as follows: comparing the tower crane operator's corresponding working status evaluation coefficient with the tower crane operator's working status evaluation coefficient threshold stored in the database; if the tower crane operator's corresponding working status evaluation coefficient is less than the tower crane operator's working status evaluation coefficient threshold, then it is judged that the tower crane operator's corresponding working status is not serious; otherwise, it is judged that the tower crane operator's corresponding working status is serious.
