<P>PROBLEM TO BE SOLVED: To provide an air conditioning control device properly detecting the presence or absence of a human in a room with a simple structure. <P>SOLUTION: A control section refers to temperature data detected by a plurality of infrared ray sensors arranged to detect respective temperatures of areas formed by dividing a space in the room in a row, that is, temperatures of elements E1-E8, in every predetermined measurement cycle (S1), determines a difference ΔT between previously measured temperature data T<SB POS="POST">n-1</SB>and presently measured data T<SB POS="POST">n</SB>with respect to the infrared ray sensors, and detects a value with the absolute value of the difference ΔT reaching a predetermined value or more as significant temperature difference data (S2). A human detection group is registered in the position of the infrared ray sensor having the positive code of the significant temperature difference data (S7), and a human detection group registered in the position of the infrared ray sensor concerned is removed with respect to the infrared ray sensor having the negative code of the significant temperature difference data (S8). <P>COPYRIGHT: (C)2012,JPO&INPIT |
