Abstract

The present invention relates to a device that can open or close a door or window by using an optical sensor. In general, an external transmitter (remote control, etc.) or an open / close device must be installed outside to open or close a door or window. Features of the invention is to generate an optical signal from the switchgear device so that the user can open and close the door or window without a separate switchgear from the outside only by the password entered into the nonvolatile memory 33 of the switchgear installed inside the user If there is only an object capable of refracting a signal such as a finger 202 is characterized in that it is configured to open and close the door or window through the optical signal receiving unit 20 and the conversion unit 21 without a separate transmission device.

Also, for security, the password was stored in the nonvolatile memory 33 of the switchgear so that the stored contents are not damaged even when the power is cut off. The number of the nonvolatile memory 33 is converted by converting the optical signal into a number in the conversion unit 21. It is characterized in that the system control unit 30 is configured to open and close the door or window only when it matches.

Description

Automatic Door / Window Opening / Closing system using optical sensor}

The present invention relates to a device that can open and close the door or window using an optical sensor, and relates to a device that can open and close the door or window without a separate switch from the outside only by the password initially input by the user.

In general, in order to open or close a door or window, a person must open or close a device that opens or closes with a key or directly inputs a password. In addition, in order to open or close the door or window wirelessly, a signal generating device (remote control, etc.) must be carried at all times. When controlling the opening and closing of the door with a wireless device, each individual must have a signal generating device, There may be a problem with the security of the door opener. In addition, in case of externally installed switchgear, such as digital door lock, if you repeatedly press the number button, a mark may be left on the frequently used number, which may cause a leak of the password, except for the wireless device mentioned above. Since it is installed outside, there is a risk of damage. Nevertheless, with the exception of the key, it is not easy to be widely used because the price is very expensive to configure the door opening and closing device with products such as wireless devices and digital door locks.

Therefore, the present invention is to solve such a problem, the present invention is to open and close the door or window only if there is an object that can reflect the signal, such as a finger by generating an optical signal inside without leaving a special external transmission device or switchgear outside For security, the password is entered in the nonvolatile memory of the switchgear, and the door or window can be opened and closed only when the password is matched.

In the case of doors or windows that are used by several people, each individual can enter the unique number and password into the nonvolatile memory to open or close the door or window. It can be left in memory.

In order to achieve the above object, the present invention is a door / window automatic opening and closing device using an optical sensor block 10 for transmitting the optical signal to the outside, receiving the optical signal (20) block for converting the number 21 (21) , The operation setting unit 31 for storing the password and the nonvolatile memory block 33, the system control unit 30 for controlling the operation and the overall operation, the block 34 for displaying the password, the door / window opening and closing device Block 40 for controlling the operation, the block 50 for driving the door / window opening and closing device.

The door / window opening and closing device using the optical sensor of the present invention configured as described above will be described below.

According to the present invention, after pressing the button of the operation setting block 31 to set a password, the signal of the optical signal generator 10 is covered by an object capable of reflecting and refracting a signal such as a finger, so that the signal is transmitted to the optical signal receiver 20. To be received.

When the optical signal is input, the operation display unit 34 blinks for several seconds, and the user confirms the optical signal input and forms the password input ready state.

While refracting a signal to a reflective object such as a finger through the optical signal generator 10 and the receiver 20, the optical signal converter 21 increases the number from 0 to 9 by the number and displays the motion display 34. When the reflective object such as a finger is removed, the increasing number stops, and finally, the number displayed on the operation display unit 34 is input to the nonvolatile memory 33.

As described above, when several passwords are input to the nonvolatile memory 33 and password input is completed, the passwords set on the operation display unit 34 are displayed in the order of input, and the user inputs the correct password. Enter the standby mode to form a password to receive.

When the user refracts the signal for several seconds or more in the standby mode through the optical signal generating unit 10 and the receiving unit 20, the optical signal generator 10 and the receiving unit 20 are configured to receive a password.

When the signal generated by the optical signal generator 10 is refracted by a finger or the like and input to the receiver 20, and the optical signal generation signal is refracted and input to the system controller 30 through the receiver 20, The system controller 30 is configured to select a desired number by increasing the number in the optical signal converter 21 during the time of the received signal. That is, the signal generated by the optical signal generator 10 By adjusting the time to be refracted to be used to select the desired number from 0 to 9. The generated signal is converted into a voltage through the receiving element 203 and the optical signal converter 21 of the optical signal receiver 20 It is converted and input to the system controller 30, and the system controller 30 is displayed on the password display segment 305 while increasing the number from 0 to 1 while the signal is input. When the user matches the first number of the password input in advance, if the object that refracts the optical signal such as a finger is removed, the signal generated by the optical signal generator 10 disappears and the optical signal receiver 20 Since the signal is no longer received, the system controller 30 stores the number displayed on the password segment 305 display inside the system controller 30 and lights the first LED of the password status indicator lamp 306 to indicate that the input is completed. In the same manner as described above, the number of passwords previously input is repeatedly input, and the system controller 30 is configured to verify whether the password matches the password input to the nonvolatile memory 33. do.

If the password matches in the operation system control unit 30, the driving unit 50 is formed to open or close the door or window through the operation control unit 40. In the system fishery, the first password is input and is refracted even after several seconds. If there is no optical signal, the system control unit 30 is configured to invalidate the input value and switch to the standby mode.

The memory block is configured of a nonvolatile memory so that the stored contents are not damaged even when the power is cut off.
