Abstract: A work machine loads materials onto a conveyance vehicle. A system for controlling the work machine includes a detection device that detects an operation of the conveyance vehicle, and a controller that controls the work machine. The work machine includes a work implement attached to a rotating body. The controller acquires operation data indicative of an operation of the conveyance vehicle from the detection device.

Abstract: A system controls a work machine that loads materials onto a conveyance vehicle. The system includes a controller and a detection device. The controller controls the work machine in an automatic control mode in which work is performed automatically. The detection device detects a presence of a person in a peripheral region of the work machine. The automatic control mode includes a loading mode in which the work machine is caused to move to perform loading work for loading onto the conveyance vehicle, and an other mode other than the loading mode. The controller causes the automatic control mode to transition from the other mode to the loading mode when a predetermined transition condition is satisfied. The predetermined transition condition includes non-detection of a person by the detection device.
