Title: WARNING DEVICE, WARNING MANAGEMENT DEVICE, ATTACHMENT DEVICE, TERMINAL DEVICE, AND WARNING PROCESSING METHOD
Abstract:
When a short-distance wireless signal that is transmitted from a transmission unit (760A) of a warning device (700A) and includes identification information of the warning device (700A) is received, a reception unit (810) of a terminal device (800) sends the identification information to a control unit (830). The control unit (830) that has received this identification information calculates a detection result for the electric-field strength of a reception result by each of a plurality of antennas having mutually different directionality in reception sensitivity in the reception unit (810), and calculates, on the basis of a calculation result by an imaging unit (820), a direction (approach direction) in which a moving body (MV) approaches a person to be warned who is carrying the warning device (700A). The control unit (830) then transmits, to the warning device (700A) by way of a transmission unit (840B), approach information including the calculated approach direction and the identification information of the warning device (700A). At the warning device (700A) that has received this approach information, a control unit (720A) causes an actuator element of a warning unit corresponding to the approach direction to vibrate.
