Automatic door, automatic door control method, control device and train

Abstract

The invention relates to the technical field of automatic doors, and provides an automatic door, an automatic door control method, a control device and a train. The control method comprises the stepsthat the opening and closing state of the automatic door is obtained; when the automatic door is in a closed state, whether a trigger object exists in a first detection area or not is judged; if the trigger object exists in the first detection area, the automatic door is controlled to be opened; when the automatic door is in an opened state, whether a trigger object exists in a second detection area or not is judged; if the trigger object exists in the second detection area, the automatic door is controlled to be kept in the opened state; and the first detection area is positioned in the second detection area, and the range of the first detection area is smaller than that of the second detection area. According to the method, whether the automatic door is opened or not is judged through the first detection area, whether the automatic door is closed or not is judged through the second detection area, and through the design, convenience of two or more persons continuously passing throughthe automatic door can be improved on the basis of avoiding mistaken opening of the automatic door.

Description

Technical field [0001] The invention relates to the technical field of automatic door control, in particular to an automatic door, an automatic door control method, a control device and a train. Background technique [0002] Automatic door refers to a door that can be opened automatically when someone approaches and can be closed automatically when no one approaches. It is widely used in various buildings, vehicles, and industrial equipment. [0003] An automatic door is provided in the related art. The automatic door includes a controller, a photoelectric sensor switch, a driving device, and a door panel. The photoelectric sensor switch is used to detect whether a target is approaching in the area in front of the door panel, and transmit the detection result to the controller to drive The device drives the door panel to move under the control of the controller to realize the opening and closing of the automatic door. The control method of the above-mentioned automatic door is: wh...

Problems solved by technology

[0004] It can be seen from the above description that the detection result of the photoelectric sensor switch is the control basis for the controller to control the automatic door. However, when the detection area of ​​the photoelectric sensor switch is large, pedestrians who enter the detection area may not want to pass through the automatic door, which will cause the automatic door to fail. When the detection area of ​​the photoelectric sensor switch is small, the detection area needs to be re-triggered every time it passes through, resulting in unnecessary pauses when more than two people pass through the automatic door continuously
