Abstract
A site management system is provided with a server that acquires information about a construction machine and a construction machine operator at a construction site through a communication channel, and manages work conditions at the construction site. The server includes an information registration unit that acquires and registers position information, acceleration data, and gyro data of the construction machine and the construction machine operator, and a riding determination unit that determines a proximity state between the construction machine and the construction machine operator from the position information of the construction machine and the construction machine operator, and determines whether or not the construction machine operator is riding the construction machine from the acceleration data and gyro data of the construction machine operator in addition to the proximity state.
