Abstract:
A moving body detection method for transmitting and receiving signals in such a manner that moving bodies can detect each other comprising:identifying a type of moving body to which a body belongs; transmitting an ID code for identifying a moving body and giving the moving body a priority with respect to each type as an ID code of a fixed period; receiving ID code signals for each moving body from other moving bodies; determining an ID code received from a moving body to determine if a neighboring upper order moving boy belongs to the same type; determining if an ID code of a higher order than a moving body is present or not within a prescribed distance; determining the presence of a moving body of a same type neighboring upper order moving body; and transmitting a response signal only when a same type neighboring upper order moving body is determined not to be present when a detection signal transmitted from a detection side moving body is received.
