Abstract
The present invention provides a swing door opening/closing detection system capable of accurately discriminating an opening/closing position of door main bodies to accordingly prevent the malfunction of the door main bodies. The swing door opening/closing detection system includes: door main bodies 12, 14 which are rotatably provided and which rotate to open/close relative to an opening part 11; 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; a sensing part 30 (28) attached to the door main bodies 12, 14 to sense a person or an object in sensing areas on paths of the door main bodies 12, 14; a deformation part 42 deforming according to the rotational operation of the door main bodies 12, 14; and a discriminating part 40 (28) which discriminates the opening/closing position of the door main bodies 12, 14 based on a deformation amount of the deformation part 42 to control the control part 24 based on the discrimination result.
