Abstract

The present invention provides an automatic door opening/closing detection system and an automatic door opening/closing detection method which are capable of preventing door main bodies from malfunctioning, for example, from being left open, even when the door main bodies are manually opened. An examplary automatic door opening/closing detection system includes: a pair of door main bodies 12, 14 opening/closing relative to an opening part; driving parts 20, 22 rotary driving the door main bodies 12, 14; a control part 24 controlling the rotary driving of the door main bodies 12, 14 by the driving parts 20, 22; and a sensing part discriminating an open position in which the door main bodies 12, 14 are open relative to the opening part, a closed position in which the door main bodies 12, 14 are closed relative to the opening part, and a partially open/partially closed position in which one of the door main bodies 12, 14 is open relative to part of the opening part and the other of the door main bodies 12, 14 is closed relative to part of the opening part, and controlling the control part 24 based on the discrimination result.

Claims

1. An automatic door opening/closing detection system comprising:

a pair of door main bodies opening/closing relative to an opening part;

a driving part driving said door main bodies;

a control part controlling the rotary driving of said door main bodies by said driving part;

a sensing part discriminating an open position in which said door main bodies are open relative to the opening part, a closed position in which said door main bodies are closed relative to the opening part, and a partially open/partially closed position in which one of said door main bodies is open relative to part of the opening part and the other of said door main bodies is closed relative to part of the opening part, and controlling said control part based on a result of the discrimination.

2. The automatic door opening/closing detection system according to claim 1,

wherein said sensing part further discriminates a position in which a person or an object exists on paths of said door main bodies, and controls said control part so as to stop the driving of said door main bodies when recognizing the position in which the person or the object exists on the paths of said door main bodies.

3. An automatic door opening/closing detection method comprising:

a position discriminating step of discriminating by a sensing part an open position in which a pair of door main bodies are open relative to an opening part, a closed position in which the door main bodies are closed relative to the opening part, and a partially open/partially closed position in which one of the door main bodies is open relative to part of the opening part and the other of the door main bodies is closed relative to part of the opening part; and

a control step of controlling, by a sensing part, a control part based on a result of the discrimination of the sensing part to control the driving of the door main bodies.

4. The automatic door opening/closing detection method according to claim 3,

wherein said position discriminating step further includes discriminating by the sensing part a position in which a person or an object exists on paths of the door main bodies, and

wherein said control step includes controlling the control part so as to stop the driving of the door main bodies when the sensing part recognizes the position in which the person or the object exists on the paths of the door main bodies.
