Abstract

PROBLEM TO BE SOLVED: To secure opening-closing control by arranging an electromotive force circuit to detect electromotive force generated in a moving piece coil by a movement to a fixed piece when a door in a stopping condition is artificially pushed in the opening direction or the closing direction, and using the electromotive force as a trigger signal to control the door opening direction or the closing direction. SOLUTION: An automatic door control device 21 is composed of a controller 7, a moving piece coil current-carrying circuit 14, an electromotive force detecting circuit 15 or the like. The electromotive force detecting circuit 15 is connected to a moving piece coil 12a. Detected electromotive force is inputted to the controller 7. The electromotive force generated when a door is artificially moved in the opening direction or the closing direction when the door exists in a closing end position or an opening end position, is used as a trigger signal to control the door opening direction or the closing direction, and control of the door opening direction or the closing direction by the controller 7 is performed on the basis of a detecting signal of the electromotive force. Therefore, accuracy of control of the opening direction or the closing direction of an automatic door is enhanced, and reliability can be improved.

2. Description of the Related Art Just passing near an automatic door,
An automatic door control device for preventing the automatic door from opening and closing is disclosed in Japanese Patent Publication No. 8-19811. The automatic door control device includes a position detection unit that detects an open / close position of the door body, a drive unit that drives the door body to open and close, and a control unit that controls the drive unit based on a signal from the position detection unit. The control unit has an opening for driving the door in the opening direction when the control unit detects that the door has performed a predetermined movement from the closed position in the opening direction based on a signal from the position detection unit. It is configured to send a signal to the driving unit. According to this device, when the door moves by a predetermined amount in the opening direction from the closed position by the hand of the passerby, the control unit determines that the passer has the intention to open the door and pass by, Thereafter, the control unit activates the drive unit to automatically open the door.

The controller drives the door in the opening direction when it detects that the door has moved in the opening direction from the closed position based on a signal from the position detector. The opening signal is sent to the drive unit, and when it is detected based on a signal from the position detection unit that the door body has stopped or substantially stopped during driving in the closing direction, the door body is opened in the opening direction. An open signal for driving the driving unit is transmitted to the driving unit. According to this device, if a subsequent passerby enters while moving in the closing direction after the preceding passer has passed and the door body is fully opened, the subsequent passerby raises his hand. Just by inserting the door and stopping or substantially stopping the door, the control unit then reversely drives the driving unit to automatically open the door. Therefore, with these automatic door control devices, it is possible to prevent the automatic door from being opened only by passing near the automatic door.

However, in each of the above automatic door opening and closing devices, the position detector detects that the door has moved from the closed position to the open direction or that the door has been driven in the closed direction. The detection of the stop or the substantial stop during the operation is used as a trigger signal for the opening direction control of the control unit. For this reason, if the detection accuracy of the position detection unit is low, a slight movement of the door in the opening direction cannot be detected, and there is a possibility that the reliability of the opening direction control cannot be ensured. The present invention has been made to solve the above problems, and an object of the present invention is to provide an automatic door control device that can reliably perform opening and closing control with a simple configuration.
