Abstract

PURPOSE: A door/window switching apparatus using an optical sensor is provided to open and shut a door and a window without an additional external transmitter by generating an internal optical signal and inputting a secret number. CONSTITUTION: A door/window switching apparatus is used for opening or shutting a door and a window by using signals of an optical signal generator(10) and an optical signal receiver(20). The door/window switching apparatus includes a system controller(30), a non-volatile memory(33), an optical signal converter(21), an operation controller(40), and a driver(50). The system controller is used for inputting a secret number into the non-volatile memory. The optical signal converter is used for converting a received optical signal to a number. The door and the window are opened and shut by the operation controller and the driver.

Description

Automatic Door / Window opening / closing system using optic sensor}

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

In general, in order to open or close a door or window, a device for opening or closing a key or entering a password must be installed outside. 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 by a wireless device, a signal generating device must be provided for each individual. Problems may arise in the security of the door opening and closing device. In addition, in the case of an externally installed switchgear, such as a digital door lock, pressing a number button repeatedly may leave a mark on a frequently used number, which may cause a leak of a password. Since the device is installed outside, there is a risk of damage. Nevertheless, except for the key, it is not easy to be widely commercialized because the price is very expensive to construct a door opening and closing device with a product such as a wireless device or a digital door lock.

Therefore, the present invention is to solve such a problem, the present invention is to provide an optical signal from the inside without having a special external transmission device or switchgear to the outside if there is an object that can reflect the signal such as a finger or door or window For security, the password is entered in the inactive memory of the switchgear, and the door or the window can be opened and closed only when the input password matches.

In case of doors or windows that are used by several people, each unique number and password can be entered in the inactive memory to open or close the door or window. I left it.

In order to achieve the above object, the door / window automatic opening and closing device using the optical sensor of the present invention, the block 10 for transmitting an optical signal to the outside, the block for receiving the optical signal (20) number conversion 21 , The operation setting unit 31 for storing the password and the inactive memory block 33, the system control unit 30 for controlling the operation and the overall operation, the block 34 for displaying the password, the operation of the door / window opening and closing device It consists of a block 40 for controlling the block, 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. Form to be received.

The operation display unit 34 blinks for a few seconds when an optical signal is input, confirms the optical signal input to the user, and forms a password input ready state.

The optical signal converter 21 transmits 0 to 9 as a number to the operation display unit 34 as long as the user is refracting the signal through the optical signal generator 10 and the receiver 20. When the reflective object such as a finger is removed from the desired number, the number of the optical signal converter is formed to be input to the inactive memory 33.

When the password is input to the inactive memory 33 as described above and the password input is completed, the password set in the operation display unit 34 is displayed in the input order to confirm whether the user entered 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.

The optical signal converter 21 transmits 0 to 9 as a number to the operation display unit 34 as long as the user is refracting the signal through the optical signal generator 10 and the receiver 20. When the reflective object such as a finger is removed from the desired number, the system control unit 30 is configured to verify whether the number of the optical signal converter matches the password inputted to the inactive memory 33.

If the password matches the operating system control unit 30 is formed to open and close the door or window through the operation control unit 40.

The memory block is configured as an inactive memory so that the stored contents are not damaged even when the power is cut off.
