<p><P>PROBLEM TO BE SOLVED: To provide a tailgating sensing device for much more accurately sensing tailgating with a simple configuration. <P>SOLUTION: The tailgating sensing device is provided with: an authentication device 11 for authenticating an authentication candidate based on authentication information unique to the authentication candidate; a load sensor group 12 composed of a plurality of load sensors for detecting weights or pressures to a plurality of load decision regions obtained by dividing a floor face of a tailgating detection region DA through which an authenticated person authenticated by the authentication device 11 passes when entering a security area SA into prescribed areas or less for each load decision region; a calculation means 13 for calculating the number of simultaneous groundings to the floor face in a predetermined tailgating decision time based on the detection region information showing the detection region as the load decision region where the weights or pressures have been detected by the load sensors; and a tailgating detection means 14 for comparing the number of simultaneous groundings with the number of estimated groundings of the authenticated person, and for detecting that a person other than the authenticated person exits in the tailgating detection region DA. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
