Abstract
Provided is a sensor for supplying and cutting off power, and more particularly, a counting apparatus and a method for recognizing entrance/exit directions which efficiently supply or cut off the power by sensing the number of entrance/exit users without an error.
Claims13
A counting apparatus for recognizing entrance/exit directions, comprising:
- a first sensing unit configured to be disposed within an object space, sense a moving body within a first sensing range which is configured to be at an entrance/exit side or toward an adjacent portion to the entrance/exit side;
- a second sensing unit configured to be disposed within the object space and sense a moving body within a second sensing range which is configured to be toward a space spaced apart from the first sensing range at a predetermined distance;
- a third sensing unit configured to be disposed within the object space and sense a moving body within a third sensing range which is configured to be toward a space between the first sensing range and the second sensing range;
- and
- a control unit configured to confirm whether the moving body is sensed by the first sensing unit or the second sensing unit when the moving body deviates from the third sensing range to increase a count of the moving body by +1 when the second sensing unit senses the moving body and reduce the count of the moving body by −1 when the first sensing unit senses the moving body.

A counting method for recognizing entrance/exit directions, comprising:
- sensing, by a first sensing unit, a moving body when the moving body is entered;
- sensing, by a third sensing unit, the moving body;
- confirming whether the first sensing unit or the second sensing unit senses the moving body when the moving body deviates from a third sensing range;
- increasing a count of the moving body by +1 when the second sensing unit senses the moving body;
- sensing, by the second sensing unit, the moving body when the moving body exits;
- sensing, by a third sensing unit, the moving body;
- confirming whether the first sensing unit or the second sensing unit senses the moving body when the moving body deviates from the third sensing range;
- and
- reducing the count of the moving body by −1 when the first sensing unit senses the moving body;
