Claim:
An apparatus for recognizing an entry/exit direction of a moving body, comprising: a first moving body detection sensor positioned at an entrance side of a specific object space or a portion adjacent thereto; a second moving body detection sensor positioned in an inner side direction of the specific object space from a position where the first moving body detection sensor is positioned; and a control means connected to the first and second moving body detection sensors by wire/wireless so as to recognize as an entry of a moving body only when, after moving body detection signals of the first and second moving body detection sensors are received simultaneously or together for a first predetermined time, the moving body detection signal of the second moving body detection sensor is not lastly received, and to recognize as an exit of a moving body only when, after moving body detection signals of the first and second moving body detection sensors are received simultaneously or together for a first predetermined time, the moving body detection signal of the first moving body detection sensor is not lastly received.
