Abstract
A work machine control system includes: a monitoring apparatus that detects a position and an action of a person in a monitored area set around a hydraulic excavator; and a controller that generates a control signal for limiting an action of the hydraulic excavator on the basis of a positional relation between the hydraulic excavator and a detected person detected by the monitoring apparatus, and controls the hydraulic excavator on the basis of the control signal. The controller determines which of a cooperating worker and a non-cooperating worker the detected person is, on the basis of an action of the detected person; and changes an allowable velocity of the work machine at a time of limiting an action of the work machine on the basis of a result of the determination or on the basis of the result of the determination and the action of the work machine.
