Description

Optical control remote control and remote control system using the same {Remote Control System by Photo Sensor}

The present invention relates to a remote control system (REMOTE CONTROL SYSTEM) for remote control of the operation of the electronic device through wireless communication, in particular, a photo sensor (PHOTO SENSOR) on one side of the remote controller (REMOTE CONTROLLER) ) And its control means to control the operation of the remote control according to the amount of light, contrast, color, etc. of the light output from a visual display device (e.g., a monitor, a display board, a liquid crystal display, an LED, etc.) or natural light (sunlight), The purpose of the present invention is to remotely control the operation of various devices through the visual display device.

As is well known, the wireless remote control system is a system for controlling the operation of main body devices (eg, televisions in the case of a television) located at a short distance or a long distance through a remote controller. It is used in almost all industries, from household goods such as air conditioners, remote control cars (REMOTE CONTROL CARs), toys, lights, and robots to industrial machines.

The core of the remote control system is a remote controller for wirelessly transmitting control commands and a remote controller receiving unit for receiving a signal transmitted from the remote controller.

As shown in FIG. 1, the remote controller 10 includes a switch manipulation unit 11 composed of a plurality of switches operated by a user; A transmitter 13 for wirelessly transmitting a control command; A control unit connected between the switch operation unit 11 and the transmission unit 13 to output a control command corresponding to a signal input through the switch operation unit 11 to transmit the control command to the main body of the electronic device through the transmission unit 13. 12, the remote control receiver 20 includes: a receiver 21 for receiving a signal transmitted from the transmitter 13; And a signal processor 22 for signal-processing the signal received through the receiver 21 to decode the operation command input by the user and transmitting the signal to the main body of the electronic device.

The remote control and the remote control receiver have a difference in the method of performing wireless communication according to the control distance. In general, the remote control uses an infrared method and a remote method uses an RF method. Most electronic devices encountered in daily life consist of infrared remote control.

Figure 2 shows the basic configuration of the remote control and the remote control receiver for wirelessly controlling the operation of the television using the infrared method.

In the case of Figure 2, when the user presses any one of the switches of the switch control unit (11a) consisting of a key matrix, it is detected by the transmitting IC (12a) to generate a corresponding signal and put on the infrared remote control receiver 20a Will be sent to.

Then, this is received by the receiving unit 21a of the remote control receiving unit 20a and converted into an electrical signal, and amplified and detected through the amplifying circuit 22a and the detecting circuit 22b, and then the waveform is formed through the waveform shaping circuit 22c. Will be shaped. The waveform shaped through the waveform shaping circuit 22c is inputted to the code judging circuit 22d to read which control command the switch pressed by the user indicates, and controls the operation of the television according to the reading result. Done.

That is, when any one of the switches in the switch control unit 11a of the remote controller 10a is pressed, it is detected by the transmitting IC 12a and outputs a signal indicating the pressed switch, and the output signal is a transmitter. The infrared light emitting diode of 13a is converted into an infrared signal and transmitted. Then, the infrared signal transmitted from the transmitter 13a is received by the light-receiving diode (hot diode) of the receiver 21a and converted into an electrical signal to perform amplification, detection, and waveform shaping operations, and then through the code discrimination circuit 22d. Determine which switch was pressed by the user.

After determining the switch pressed by the user by performing the above process, a signal indicating this is input to the control unit (microcomputer) of the electronic device (television). Then, the television control unit (not shown) controls the operation of the television according to the input signal to perform the operation indicated by the switch pressed by the user.

That is, by operating a switch for controlling the power ON / OFF, volume, channel, color, contrast, etc. through the remote control to transmit the corresponding signal wirelessly, it is received by the remote control receiver installed in the television Will control the operation of.

This control principle differs only in the transmitted signal and transmission method (RF method, infrared method), and is commonly used in other remote control systems.

For example, the RC car forwards, reverses, and rotates left and right commands, and in the case of a remote control toy, a command to control the operation of the corresponding toy, and in the case of a remote control industrial device, the control command is wirelessly transmitted. It controls the operation of RC cars, toys, and industrial equipment.

However, in the case of the conventional remote control as described above, since the operation is only relied on by the user's manual operation, there is no remote control around the user, or the user is difficult to operate the remote control due to other operations or other causes. In this case there was a problem that can not control the operation through the remote control.

For example, in the case of a lamp, a boiler, a fan, an air conditioner, or a television operated by a remote controller, the user cannot operate the remote controller until the user directly operates the remote controller. there was.

In addition, in the case of toys operated by the remote control, only the operation by the remote control is possible, and thus there is a problem that the efficiency of the fun or educational effect is reduced.

For example, in the case of RC cars or toys, it was inconvenient to continuously operate the switch at an appropriate time to perform continuous operation.

An object of the present invention is to solve the conventional problems as described above, in particular, according to the amount of light, contrast, color, etc. of light output from a visual display device such as a computer monitor, a liquid crystal display, an LED, an electronic sign, etc. By controlling the operation of the main body of the electronic device by controlling the operation of the light, the remote control of the main body of the electronic device only by the incident form of the light input to the light receiving unit, as well as control using the operation switch 'light control To provide a remote control and a remote control system using the same.

That is, an optical sensor and a control unit are mounted on one side of the remote controller so that a predetermined control command is output according to the display form output from the visual display apparatus or the incident form of natural light so that the operation of the main body of the electronic device can be performed through the visual display apparatus. It is to.

For example, in the case of the blind that is controlled by the remote control to control the lighting of the room, the control code is used to control the amount of natural light (sunlight) incident on the room automatically. In order to control the operation of the main body of the electronic device, one or more optical sensors are mounted on the rear surface of the remote controller and connected to each switch of the remote controller switch operation unit by OR logic, and a computer program is controlled to control the operation of the optical sensor at a specific position of the monitor. After configuring the screen corresponding to the attachment position to invert the contrast or change the color, and attaching the remote control to the screen display position of the monitor, the operation of the remote controller is controlled by controlling the operation of the remote controller according to the display form output to the monitor. You can control the operation.

In addition, when using other visual display devices such as a liquid crystal display, an LED, or an electronic sign, each control circuit corresponding to the display device controls the output form of the light and wirelessly controls the operation of the main body of the electronic device according to the output form. It is to.
