In step 2, when alarm information is received, an alarm operation is performed (step 5). In the alarm operation, it is preferable that the vibration of the vibrator 31 and the sound output from the sound source unit 32 are output together with the change of the light emission state in the light emitting unit 40. It is more preferable to provide a timer function so that the alarm information changes with the passage of time from the start of the alarm operation. For example, in the first time zone from the start of the alarm operation, the light emission state of the light emitting unit 40 is changed, and then the vibration of the vibrator 31 and the sound output of the sound source unit 32 are performed. In this way, the wearer can grasp the dangerous situation by changing the alarm information as time elapses from the start of the alarm operation.
In the state of step 5, the control unit 26 monitors the presence or absence of impact detection by the impact detection unit 25 (step 6). When the signal from the impact detector 25 is not detected, the alarm operation is continued. When the control unit 26 detects a signal from the impact detection unit 25 when the wearer strikes the helmet 10, the alarm operation is stopped (step 7), a signal is transmitted from the transmission unit 26, and the wearer recognizes the alarm. This is notified to the remote person (step 8). In addition, after transmitting the response signal in step 8, it returns to step 2 and performs alarm monitoring.
