Description

Universal remote control device, power supply and control methods

The present invention relates to a power supply device and a remote control device, and more particularly, to perform a universal remote control function, to supply or cut off power to a commercial household appliance according to a preset time, and to perform a predetermined function. An apparatus and a control method thereof are provided.

Recently, with the development of the residential environment, energy consumption is increasing due to the emergence of new home appliances and the combined use of various home appliances for a comfortable and convenient living environment, and measures for this are urgently required.

As a countermeasure against this, a method such as an outlet power supply control device or a power adapter system has been proposed.

First, the " wireless timer outlet power control device " described in Registration Utility Model 20-0227804 is composed of a plurality of wireless timer outlets and a dedicated remote controller to control the power supply of the wireless timer outlets with the remote controller. The "Wireless Timer Outlet Power Control Unit" allows the on / off control of the power supply of the wireless timer outlets individually, but the timer setting and display for the timer function is only possible at each timer outlet. Since it is installed behind a home appliance that is difficult to reach and the view is not secured, the setting and checking of the timer is inconvenient, and a setting input device or a display device must be provided for each timer outlet, thereby increasing manufacturing costs.

In addition, the "Wireless timer outlet power control device" only supplies or cuts power to the appliances connected to each timer outlet, so that appliances equipped with the standby mode (air conditioner, TV, audio, etc.) may be turned on or off. The appliance cannot be operated or stopped.

Therefore, there is a problem that can not expect energy savings due to the operation time of the home appliances. For example, in the case of an air conditioner, if the 10-minute operation and the 50-minute stop are repeatedly set during sleep, a considerable amount of energy is saved while maintaining proper cooling throughout the bedtime. The operating method of the air conditioner operates or stops automatically by comparing the set temperature with the present temperature. Therefore, if the set temperature is set low, the power consumption is considerable, and in general, various timer functions such as repetitive operation function by operation time interruption are not provided. It is not.

In addition, the conventional "wireless timer outlet power control device" because the home appliance immediately cuts off the power supplied without going through the standby mode, such a method has a problem that the life of the device may be shortened or broken.

In addition, the conventional "wireless timer outlet power control device" does not operate even if the user operates the device with a remote control attached thereto to operate the home appliance in a state in which power supply is cut off by a timer setting or a remote setting. There is a problem that can be mistaken and the inconvenience of having to operate the device again after supplying power.

In addition, the "wireless timer receptacle power control unit" has to operate an additional remote control for supplying or disconnecting another remote power together with a number of remote controls attached to various kinds of home appliances in the home, which leads to user complexity. There is a problem that further weights.

Next, the "wireless remote control power adapter system" described in the registered utility model 20-0231921 is composed of a plurality of adapters and a dedicated remote control, the power supply of the adapters can be individually supplied or cut off by the remote control, but the standby mode is provided. There is a problem in that energy savings due to the operation time of one home appliance cannot be expected.

In addition, the conventional "wireless timer outlet power control device" immediately cuts off the power supplied to the home appliance without going through the standby mode during operation, this method has a problem that the life of the device may be shortened or failure, and timer setting In the state that power supply is cut off by remote setting, even if the user operates the device with the remote control attached to it to operate the home appliance, it does not work. It has inconvenience to operate.

In addition, the conventional "wireless remote control power adapter system" has to operate a remote control for another remote power supply or shutdown and timer setting together with a number of remote controls attached to various kinds of home appliances in the home, There is a problem that further increases the complexity of use to the user.

Referring to FIG. 3, the power supply apparatus according to the embodiment of the present invention includes a power supply unit 210, an RF transceiver 220, an infrared light emitting unit 230, a storage unit 240, a power control unit 250, The outlet part 260, the switch part 270, the analog-digital converter 281, the voltage detector 282, the 1st current detector 283, and the 2nd current detector 284 are included.

The power supply unit 210 receives the commercial power and supplies power to each part in the power supply device. The storage unit 240 stores the first unique number or the second unique number as many as the number of outlets provided, and automatically generates and stores the same as necessary. This unique number is stored in advance in the outlet device, and a different unique number is assigned to every device and outlet. There is no unique number in the remote control device, and the unique number of the outlet is inputted into RF and stored in the memory and registered in the remote control device. If necessary, it can be stored in the remote control device and registered in the outlet device.

The RF transceiver 220 includes an RF antenna to perform a RF communication function.

The switch unit 270 includes at least one switch 271 and 272, and one-to-one correspondence with the first unique number or the second unique number to supply or cut off power to the outlets 261 and 262.

Next, the operation of the remote control device and the power supply device according to the embodiment of the present invention having such a configuration will be described in detail. At this time, the plugs of the devices are plugged into the outlets of the power supply.

4 is an operation flowchart of a remote control apparatus according to an embodiment of the present invention.

As shown in Figure 4, after the power of the power supply unit 110 is applied to receive a desired function from the user (S410).

When the timer function is selected, the controller 150 receives the corresponding device and the reservation time from the input operator 190 and stores the received device and the reserved time in the memory 130.

The timer function used in the embodiment of the present invention is to supply or cut off the power as set by the user when the real time generated from the real-time generator reaches a preset time by the user. The unit is minutes, hours, daily, weekly, monthly. It can be set in units of years, and for each power supply.

In addition, the timer function according to the embodiment of the present invention enables not only supplying or cutting off power to the device, but also performing a function operation, a function stop, a preset function, and the like of the device including the infrared receiver or the RF transceiver.

In an embodiment of the present invention, by turning the operation button 198 to the left and right, the cursor is positioned at the time to be reserved, and the reservation setting is performed at the power-on time by pressing the operation button 198 (S430).

5 shows a display example of the timer reservation setting by the above method.

As shown in FIG. 5, after the corresponding device (TV) is selected, between 6 pm and 9 pm of the device are displayed on time by user selection (S430).

On the other hand, when the remote control function is selected, the controller 150 assigns the operation buttons 191 to 196 of the input operation unit 190 to the remote control function to turn on or off power to the corresponding device of the input operation unit.

Then, the controller 150 outputs a control signal to the outlet in response to the signal of the input operation unit to turn on or off the power of the device.

Here, the control unit 150 outputs a power supply signal to the power supply device 200 through the RF transceiver 160, and the power controller 250 through the RF transceiver 220 when the power-on signal. The signal is received, the storage unit 240 is checked with a unique number, and the switch 271 or 272 corresponding to the corresponding outlet is turned on, thereby supplying power to the device.

Then, the controller 150 transmits a control signal through the infrared light emitting unit 170 or the RF transceiver 160 after a predetermined time and outputs a power on signal to the corresponding device to turn on the device. This concept is illustrated in FIG. 6.

Therefore, power the device safely.

In the case of the power off, the control signal is output to the device in the reverse order of the power-on, and the device is turned off. Then, the power is cut off by outputting a power off signal to the power supply device. Turn off (S440).

Meanwhile, the controller 150 checks whether the time set for the memory 130 to be turned on / off is referred to with reference to the timer 140 (S450).

If the time is set in the memory 130 to be turned on / off, the controller controls the power on or off by the above process (S460).

Meanwhile, in order to reduce power consumption of the power supply itself, the power control unit 250, the memory unit 240, the voltage detector 282, the current detectors 283 and 284, and the RF transceiver 220 may enter a sleep mode. Make it work only when needed.

Standby power in home appliances, etc., is consumed when the device is not used, which is about 10% of Korea's domestic and commercial power consumption (Energy Management Statistics). For example, a TV that is turned on by an infrared remote control even when the TV is turned off means that the infrared receiver of the TV is operating to detect an infrared light signal, which is standby power.

The way to remove this standby power is to unplug the TV's power cord, which is generally annoying and rarely done. Therefore, in the present invention, the power supply (standby power) can be cut off at all during the time when the device is not used (generally, 12 pm to 6 am, etc.). In addition, in the embodiment of the present invention, when the device is turned off from the remote controller, the power supply may be cut off after a predetermined time after the device is turned off, and the device is operated by grasping a tendency of power consumption during operation and standby power consumption. If you go to standby (the user has finished using the device), you can shut off the power supply after a certain amount of time. Such matters may be achieved by controlling the power consumption by the controller 150.

In addition, in the case of a device without a standby mode, for example, the electric mat, the ondol bed, the heater, the cold / hot water machine, the food waste processor, the fan, and the like may interrupt the power supply through the timer setting.

On the other hand, in the case of a device having a standby mode (infrared light or RF remote control), typically, air conditioners, TVs, etc. save energy by performing a function operation / stop function of the device with the supply / interruption of the power supply with a timer.

In the embodiment of the present invention, since it is complicated to operate a plurality of power supplies (various devices connected to) by using a single remote controller, the remote controller is provided with a one-to-one operation button corresponding to the power supply and presses a button of the corresponding device. It operates as a remote control of the device (when remote control is operated, the control signal corresponding to this device is sent to the device, in the remote control mode), and in the timer mode, it operates as an input control unit for setting the timer of this device.

Meanwhile, in the exemplary embodiment of the present invention, in the case of the infrared ray receiving device, the infrared ray transmitting unit 230 transmits an RF signal to the power supply device 200 remotely from which the infrared ray signal of the remote control device does not reach. The infrared light signal may be transmitted through the optical fiber 210 to operate the device (for example, a TV). This is illustrated in FIG. 7.

That is, you can turn off the volume control or power off the TV in the living room using the remote control in the room. The operation is briefly described as follows.

The control unit 150 of the remote control device 100 transmits a signal to turn on / off the power through the RF transceiver 160 to the power supply device 200.

Then, the signal is received through the RF transceiver 220, the power control unit 250 converts the RF signal into an infrared signal, the infrared signal for power on / off through the infrared light emitting unit 230 TV or air conditioner And so on.

Through this process, remote control is possible, and if necessary, control of a function operation / function stop, etc. of the device may be performed after power is supplied to the power supply device 200.

On the other hand, the advantages of using the optical fiber 210 without using the electrical wiring to the signal relay of the infrared transmitter 230 is as follows.

First, when the electric wiring is used, it is troublesome to draw two strands of the signal line, connect the infrared light emitting element to the end of the signal line, and draw it to the outside. However, since the optical fiber 210 draws only one strand and transmits the optical signal through the fiber 210, there is no need for an infrared light device at the end.

Second, in the case of electric wiring, there is a risk of electric shock when the coating is peeled off and the wire is exposed to the outside. However, the optical fiber 210 has no risk of electric shock.

In addition, in the embodiment of the present invention provided with a first unique number (the unique number of the power supply) and the second unique number (the outlet unique number) can be controlled by having a plurality of outlets in one power supply, respectively, Advantages of having a plurality of outlets is that it is possible to control a plurality of outlets with one case, RF wireless transceiver, control unit, etc., respectively, and the cost is reduced, and a power supply device 200 to be wirelessly communicated with the remote control device 100 (200). Since the number of) decreases, the wireless communication error can be reduced and the communication speed can be increased.

In the embodiment of the present invention, power consumption and integrated power can be measured, which is performed for each outlet in the power supply.

First, the instantaneous voltage v (t) is measured by the voltage detector 282, the instantaneous current i (t) is measured by the current detectors 283 and 284, and values obtained by multiplying each other by the power controller 250 are obtained. After integrating for the unit period (T) and dividing by the unit period to obtain the instantaneous power consumption (P), which is shown in Equation 1 below, the unit becomes ㎾.

In addition, the integrated power (E) is a cumulative value of the instantaneous power consumption used per unit time, the unit is ㎾h, it is obtained by the following equation (2).

The unit time refers to the time of the timer 140 of the remote control device 100 and wirelessly transmits the power to the power supply device 100 at a predetermined cycle.

The electric charge is calculated by the controller 150 by referring to the power unit price information stored in the memory 130 for the accumulated power E received wirelessly from the power supply device.

The progressive electric charge is calculated by the control unit 150 of the remote controller by referring to the power unit price information for each progressive section stored in the memory 130 for the accumulated power E received wirelessly from the power supply device 100, and calculated as necessary. May be performed by the power control unit 250.

In addition, in the embodiment of the present invention, the remote control device 100 is provided with a password lock function to protect the child from changing the timer setting, and the child may be used together with the plug lock device 290 shown in FIGS. 8 and 9. You can also limit the amount of time you spend watching TV or using your computer.

The password feature on the remote allows you to set the lock or unlock for each power supply.

8 or 9, the plug locking device 290 of the power supply is a physical means, and has a hole in the power supply 200 so that the plug and hole cannot be easily released. Tie up using a back to prevent the plug from coming off.

In addition, in the embodiment of the present invention, the instantaneous power, integrated power, electricity rate, and progressive electricity rate are displayed on the display unit 120 so that the user can save energy by checking the electricity usage in real time. In addition, there is an advantage that it can also prevent entering the progressive stage, instantaneous power has the advantage that the consumer can see the power consumption of the device at a glance induces manufacturers to lower power production of the device.

In addition, the infrared light receiving unit 180 may receive the transmission signal of the infrared light remote controller attached to various kinds of devices according to various manufacturers and register it in the remote control as necessary. It is preferable to store a lot of manufacturers or devices in the market in advance in the memory 130, but a rare manufacturer or device transmits the necessary functions of the remote control included with the device to the infrared light receiving unit to receive this signal and to the remote controller. This is to register and use in place of the remote control attached to the equipment.
