Referring to FIG. 1, the door opening/closing control device of the present invention includes a sensing unit 10, a control unit 20, and a door lock driving unit 30.

The sensing unit 10 detects the opening and closing direction and the opening and closing state of the door D and outputs a signal for operating the door lock driving unit 30 to the controller 20.

The control unit 20 controls the door lock driving unit 30 by determining a direction in which the door D is opened and a state in which the door D is opened and closed according to a signal detected by the detection unit 10.

The door lock driving unit 30 drives the door lock 310 installed on the outdoor floor where the door D is installed so as to appear and protrude to prevent the door D from being reopened while it is being closed.

Specifically, the sensing unit 10 includes a first sensor 110, a second sensor 120, and a third sensor 130 for sensing the opening and closing direction of the door D and the opening and closing state.

Referring to FIG. 2, the first sensor 110 and the second sensor 120 are installed on the outdoor floor where the door D is installed to detect the opening and closing of the door D, and transmit the detected signal to the control unit 30 ).

The first sensor 110 is installed at a position close to the door D on the outdoor floor, and the second sensor 120 is installed farther from the door D than the first sensor 110 on the outdoor floor. .

The positions of the first sensor 110 and the second sensor 120 are set according to the detectable range.

The third sensor 130 is installed on the door frame of the door D to detect the open/close state of the door D, that is, the closed state of the door D, and output the detected signal to the controller 30.

Various types of sensors capable of detecting the operation of the door D may be used as the first sensor 110, the second sensor 120, and the third sensor 130.

For example, a magnetic sensor, an infrared sensor, and a photo sensor may include at least one of a sensor capable of detecting an operating state of a door, and preferably a magnetic sensor. This does not limit the type of sensor, and of course, any sensor capable of sensing the opening and closing of the door D may be used without limitation.

When the control unit 20 receives the detection signal transmitted from the sensor unit 10 and detects that the door D is closed, the control unit 20 outputs a driving signal that operates the door lock driving unit 30 to prevent the door D from being opened. Make it possible.

Here, the controller 20 determines that the door D is opened when the detection signal is input in the order in which the movement of the door D passes through the first sensor 110 and reaches the second sensor 120, and When the detection signal is input in the order in which the movement of (D) passes through the second sensor 120 and reaches the first sensor 110, it is determined that the door D is closed.

Accordingly, when it is determined that the door D is closed, the control unit 20 can operate the door lock driving unit 30 to prevent the door D from reopening, and when the door D is completely closed, the third sensor According to the detection signal of 130, the control unit 20 returns the driving unit 30 to its original state, so that the door D can be opened later.

3 is a perspective view of a door lock driving unit according to an embodiment of the present invention, and FIG. 4 is a view showing a state in which the door is opened and closed according to the present invention.

Referring to FIG. 3A, the door lock driving unit 30 includes a solenoid 300 and a door lock 310.

The door lock driving unit 30 is located inside the floor between the first sensor 110 and the second sensor 120 on the outdoor side.

The solenoid 300 is installed inside the bottom surface between the first sensor 110 and the second sensor 120 and operates according to a control signal from the controller 20.

The door lock 310 is capable of appearing and protruding in the groove H formed on the bottom surface, so that the door D can be opened and closed by appearing and protruding from the groove H according to the operation of the solenoid 300.

That is, as shown in FIG. 4A, when a detection signal is input in the order in which the movement of the door D passes through the first sensor 110 and reaches the second sensor 120, the controller 20 ) Is determined to be closed, and the operation signal is not applied to the door lock driving unit 30.

Thereafter, as shown in FIG. 4B, when a detection signal is input in the order in which the movement of the door D passes through the second sensor 120 and reaches the first sensor 110, the controller 20 D) is determined to be closed, and applies an operation signal to the door lock drive unit 30, and when the solenoid 300 operates according to this operation signal, the door lock 310 rises and protrudes from the groove (H) and the door (D) By preventing the door (D) from being reopened in the open direction, reopening is prevented while the door (D) is closed.

The present invention as described above may be additionally installed in a key input device or a recognition device for recognizing a user's biometric information, for example, a fingerprint, a locking device including an iris recognition device, and may be installed independently without the locking device. .

So far, we have looked at the center of the preferred embodiment for the present invention.

The embodiments described in the present specification and the configurations shown in the drawings are related to one of the most preferred embodiments of the present invention, and do not represent all the technical spirit of the present invention, and thus various equivalents and modified It should be understood that there may be examples.

There may be embodiments in which various modifications and changes are possible.

For example, in the above description, it has been described that the first sensor 110 and the second sensor 120 are installed on the outdoor floor in order to detect the direction in which the door D is opened, but it is usually rotated around a hinge axis. A device that detects a pulse generated when the door is rotated, or the direction in which the door (D) is opened or closed by an electrical signal from a switching means that is electrically ON/OFF according to the opening and closing of the door (D). I can.

In addition, in the case of the third sensor 130 that detects the open/closed state of the door D, a device that detects a pulse generated when the door rotates, which is rotatably installed around the hinge axis, or the door D It goes without saying that the closed state of the door D can be detected by an electrical signal from the switching means that is electrically turned on/off according to the opening and closing.

As a changeable embodiment, FIG. 3B is a perspective view showing another embodiment of the door lock driving unit 30. Referring to this drawing, the door lock 310a is a configuration in which the door lock 310a rotates around the fixed shaft 311 and appears and protrudes, and the power of the solenoid 300a is operated to rotate the door lock 310a through the gear transmission unit 320. You will be able to.

The gear transmission unit 320 is composed of a rack 321 and a pinion 322, the rack 321 is operated forward and backward by a solenoid (300a), the pinion 322 meshed with the rack 321 has a fixed shaft The 322 is fixed so that the door lock 310a can be rotated.

In addition, although not shown in the drawing, as a power source for operating the door locks 310 and 310a, a motor is used in addition to the solenoids 300 and 300a, and a gear transmission unit capable of converting the rotational power of the motor into a linear reciprocating motion. It goes without saying that it is possible to rotate the door lock 310a by configuring the door lock 310 to lift or move the door lock 310 or by configuring a gear transmission that transmits rotational power of the motor.
