Abstract (en)
[origin: EP1069541A2] A terminal unit (3) drives a buzzer controller (21)/LED controller (22) to give an alarm to an external when the terminal unit (3) detects the fact that an emergency information switch (23) has been depressed for a predetermined time or more. The terminal unit (3) informs a center computer (4) of an emergent state when the alarm to the external has been continued for a predetermined time. Further, the terminal unit (3) always reads a value of an acceleration sensor (17). Hence, the terminal unit (3) drives the buzzer controller (21)/LED controller (22) when recognizing the fact that the terminal unit (3) has been turned upside down for a predetermined time or more, and the terminal unit (3) informs the center computer (4) after the lapse of a predetermined time. <IMAGE>
