To verify whether or not an emergency stop terminal of a work machine which travels autonomously has any equipment failure before activation of an autonomous travel system.SOLUTION: An emergency stop system according to the present invention has at lease one of emergency stop terminals 60, 80 and a control machine 40. the control machine has an activation signal receiving unit 445 for receiving an activation signal indicating activation of an autonomous travel system, and a mode determining unit 441 for determining that when an operation of an emergency stop switch is received in a state that the activation signal is not received, it is a test mode. The emergency stop terminal has a stop control signal generating apparatus 63 for generating a stop control signal for driving an emergency stop apparatus mounted on the work machine based on a stop command signal. The stop control signal generating apparatus generates the stop control signal when receiving the stop command signal in the test mode, and returns, to the control machine, that the stop control signal can be generated without transmission to the work machine.SELECTED DRAWING: Figure 4
