Description

[0001] ENVIRONMENT ADAPTIVE TYPE MULTI-TAP AND CONTROL METHOD THEREOF [0002]

The present invention relates to a multi-tap capable of blocking standby power and a control method thereof, and more particularly, to a multi-tap capable of blocking standby power by activating or deactivating a plug socket into which a plug of a household appliance is inserted, And an environment adaptive multi-tap for minimizing power consumption by selecting activation / deactivation of a plug socket according to a user's selection, and a control method thereof.

Generally, the majority of household appliances are designed to be automatically operated according to a user's selection behavior and a set operation or operating condition, and standby power is consumed. In addition, most home appliances do not have the function of controlling the power according to the conditions such as the presence of the user and the brightness of the surroundings, so they are continuously operated according to the setting of the power switch regardless of the absence of the user.

For example, when the user sets a desired room temperature, the heating / cooling device operates until the room temperature reaches the set temperature. When the room temperature reaches the set temperature, the heating / cooling device is automatically stopped.

Standby power is required for household appliances like these. In addition, when the operation temporarily stops due to carelessness of the user, for example, when the room temperature is the set temperature value and the user vacates the room while the driving is temporarily stopped, the room temperature There has been a problem in that electric power is consumed unnecessarily since the air conditioner is automatically operated according to the change. Therefore, in the case of such household appliances, standby power consumption and power consumption due to user's carelessness can be brought about. If not used, there is a risk of fire if the power switch is not turned off in time.

A variety of multi-tabs having functions for reducing power consumption of household appliances that are required by standby power have been developed. 10-1121150, " Standby power cutoff device and method "described below automatically measures and stores an initial standby power value in a standby state of an electronic device, thereby detecting an active state of the electronic device based on the stored initial standby power value The standby state is determined, and when the standby state is established, the standby power is completely cut off through the power cutoff unit.

However, conventional multi-tap devices that block the standby power as in the above prior art can not shut off the power supplied to the home appliances only when the user of the home appliances is not injured while the home appliances are operated while only the standby power is blocked. In other words, it was not possible to activate (AC power supply) or disable (AC power cutoff) the plug socket to which household appliance was connected in accordance with the surrounding environment. Therefore, when a heater, an air conditioner, or a heater using a lot of electric power by using a multi-tap according to the conventional technology is inadvertently operated, the risk of fire is high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. It should be understood, however, that the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It should be noted that the embodiments of the present invention described below are intended to sufficiently convey the spirit of the present invention to those skilled in the art.

The case 10 of the environmentally adaptive multi-tap 1 according to the embodiment of the present invention includes a front panel 10a inclined upwards in the front direction of the horizontal floor panel 10a as shown in Figs. 1a and 1b And a socket module 11 provided with at least one plug socket 12 is provided in the rear space portion where the bottom panel 10a and the front panel 10b face each other, 10).

On the upper surface of the front panel 10b, a mode switch 16 for setting the operation mode of the multi-tap 1 and selection switches 15a, 15b, 15c, 15d (corresponding to the number of plug sockets 12 for on / And a display unit 17 are provided. At this time, the USB port 18 is provided on one of the front surface, the rear surface, and the side surface of the case 10.

The inclination angle? Of the front panel 10b inclined upward in the rear direction from the front of the bottom panel 10a of the case 10 is determined by the clock function, day of week, temperature, etc. of the display unit 17, For example, an active state, and for convenience of use of the switches disposed in the operation mode selection unit 14, it is formed at 40 to 50 degrees, preferably at 45 degrees. It is preferable that the illuminance sensor 40 and the motion sensor 42 among the circuit components of the present invention incorporated in the socket module 11 are located on the front panel 10b.

The socket module 11 of the environmentally adaptive multi-tap 1 configured as described above is connected to an AC input line (ACC) through which an external AC power is input, and the circuit shown in FIG. 2 is mounted inside the AC input line .

2, an AC power input to a hot line (AC-IN) and a common line (AC-COM) of an AC input line (ACC) consisting of the pair of lines is input to an AC-DC converter And converted into a stable DC voltage (VCC) of a constant level. A USB port 18 is connected to an output terminal of the AC-DC converter 20 so that a product requiring USB power is easily coupled.

The hot line AC-IN of the AC input line ACC is connected to a plurality of plug sockets 12, for example, of the relay 31 in the activator 30 providing the power sources AC1 to AC4 of the plug socket It is connected to switch contact.

The switch contact of the relay 31 is switched to an "on" state when a current flows to a driving coil provided adjacent thereto, which is performed when the driving transistor 32 is turned on. For example, when the control unit 50 outputs a signal of logic "high" to an output port (PCi: a positive integer of 1, 2, 3, 4, So that the switch contact of the relay 31 is attached to activate the corresponding plug socket 12. [

Therefore, when the control unit 50 outputs a logic high to the output port PC1, the power source AC1 of the plug socket enters an activation mode for outputting the AC power of the AC input line ACC as it is, PC2) outputs a logic "high ", the power source AC2 of the plug socket enters an activation mode for outputting the AC power of the AC input line ACC as it is. Conversely, when the output port PCi transitions to logic "low", the power supply AC1 of the plug socket is inactivated.

A current sensor 33 for detecting a current flowing to the power supply line is coupled to the power source AC1 of the plug socket of the activator 30. The current sensor 33 may be a CT (current transfer) type current sensor that detects a current flowing through a power supply line in a non-contact manner. The sensed current value (CSi) of the corresponding plug socket 12 sensed by the current sensor 33 is input to the controller 50.

The control unit 50 includes a memory 52 to which a program according to the power switching is mapped and controls the intensity of light emitted from the illumination sensor 40 and the motion sensor 42 according to a program mapped to the memory 52 (AC1 to AC4) of the plug sockets of the plug sockets 12 are controlled individually according to the analyzed result by analyzing the state of the illumination detection signal (light detection) and the motion detection signal and controlling the activators 30 according to the analyzed result Or collectively, and displays the result of the process through the display unit 17 connected to the output port.

The control unit 50 includes a plurality of touch light emitting buttons composed of a touch pad TCPi and a light emitting diode module LEDi disposed adjacent thereto and a mode switch 16 including a select switch 15i and a mode switch 16, (14) are connected.

The light emitting diode module LEDi includes red, blue, green, and yellow light emitting diodes that emit various colors by a lamp control signal (LCi) output from the controller 50.

At this time, the number of the selection switches 15i is set to the number of the plug sockets 12 shown in Fig. 1, and they have a 1: 1 correspondence relationship, thereby activating or deactivating the plug sockets 12 individually. Then, the mode switch 16 sets the operation mode of the multi-tap 1. Here, the operation mode is to select whether to activate or deactivate all the plug sockets 12 collectively.

The operation of the environment adaptive multi-map 1 having the above-described configuration will be described in detail with reference to the flowcharts of FIGS. 3 and 4. FIG.

When an AC voltage is input to the AC input line ACC connected to the environment adaptive multi-tap 1, the AC-DC converter 20 converts the DC voltage into a constant DC voltage and outputs a driving voltage Vcc. At this time, the controller 50 is initialized by inputting the driving voltage Vcc, and then, in step S1 of FIG. 3, it searches whether the mode switch 16 is selected. If the mode switch 16 is selected in step S1, the controller 50 controls the operation of the plug socket 12 according to the selection of the mode switch 16 and the selection switches 15a, 15b, 15c and 15d in step S2. Setting.

For example, when the user operates the power source AC1 of the plug socket continuously for 24 hours to set the operation mode to the individual lock mode and continues the selection switch 15a for selecting the power source AC1 of the plug socket for about 2 seconds The power is continuously supplied regardless of the sensing of the ambient light sensor 40 and the motion sensor 42, which will be described later. That is, the batch activation / deactivation operations are individually controlled.

If the mode switch 16 is not selected in step S1 of FIG. 3, the controller 50 determines whether the current operation mode is automatic in step S3. At this time, the operation mode is also set by the mode switch 16 described above, and the setting of the operation mode is stored in the memory 52. [ It defaults to automatic mode from the beginning.

If it is determined in step S3 that the current operation mode is the manual mode, the controller 50 determines whether the power sources AC1 to AC4 of the plug sockets are individually turned on or off according to the selection of the selection switches 15a, 15b, 15c, To be activated / deactivated. For example, if the selection switch 15a is selected, only the power supply AC1 of the plug socket is supplied with the activation control signal (" AC ") input to the activator 30 so that the AC power of the AC input line PC1) to logic "high ".

If it is determined in step S3 that the current operation mode is the automatic mode, the controller 50 determines whether the output reading light (illuminance) or motion of the illuminance sensor 40 and the motion sensor 42 is searched in step S5 . If no light or motion has been detected, the controller 50 determines that there is no user and that there is no user at step S6. In step S6, the control unit 50 determines whether a plug socket Disable power (ACi).

If it is determined in step S5 that the light or motion is searched, the controller 50 activates the multi-step in step S7. That is, the activator 30 is controlled so that the AC power of the AC input line ACC is supplied to the power source ACi of the plug socket as a whole. However, if there is a plug socket 12 that is individually set to the operation mode, the activator 30 connected to the plug socket 12 should not be controlled.

In step S7, the control unit 50 activates the multi-tap 1 and determines whether the motion is detected for a predetermined time by the output of the motion sensor 42 in step S8. At this time, if the movement has not been detected for a predetermined time, the process jumps to the above-described step S6 to deactivate the remaining power source ACi of the plug socket to be supplied with power at all times. If there is motion, .

It can be seen that the environment adaptive multi-tap 1 according to the embodiment of the present invention operates as follows.

First, the light sensor (ACi) of the plug socket is activated when the light sensor and the motion sensor detect the user and the light. That is, AC power of the AC input line ACC is supplied.

Second, the light sensor senses the light but disables the power (ACi) of the plug socket after a certain period of time if no user detection is detected by the motion sensor. That is, the AC power supply of the AC input line (ACC) is cut off.

Third, if the light sensor does not detect light, but there is user movement in the motion sensor, activate the power (ACi) of the plug socket.

Fourth, if the light sensor does not detect the light and the motion sensor can not detect the user, the ACi of the plug socket is disabled.

According to the above-described operation, the environment adaptive multi-tap 1 according to the embodiment of the present invention automatically cuts off the power of the remaining plug sockets in which the user has not set the operation individually according to the ambient illuminance and the presence or absence of the user, By supplying the AC voltage to the plug socket, it is possible to prevent unnecessary operation of home appliances due to user carelessness as well as standby power, thereby saving power consumption and preventing electric fire in advance.

Meanwhile, the controller 50 shown in FIG. 2 searches for a plug socket activated in step S10 at a predetermined period. If it is determined that there is an activated plug socket, the controller 50 reads the output of the current sensor 33 of the activator 30 of the plug socket 12 in step S11. In step S12, C.

If it is determined that the current sensed value output from the current sensor 33 exceeds the preset proper current value, the control unit 50 controls the activator 30 connected to the plug socket 12 in step S13 Outputs the output activation control signal PCi in a logic low and turns on or flickers the light emitting diode module LEDi provided in the vicinity of the corresponding selection switch 15i to notify the user of this state. At this time, the light emitting diode module LEDi may be turned on or off in a red or sequential manner.
