Description

THE AUTOMATIC BRAKING APPARATUS FOR WAITING ELECTRIC POWER AND MULTI- OUTLET USING IT

Technical Field

[1] The present invention relates to an automatic braking apparatus for a waiting electric power and a multi-outlet using the same, and in particular to an improved automatic braking apparatus for a waiting electric power and a multi-outlet using the same in which an electric power can be effectively saved in such a manner that a light and shade, a presence of human, a current consumption and a remote controller infrared ray signal are recognized, so that a system can be controlled. Background Art

[2] In the description of the present invention, the term "waiting electric power" represents an electric power which is consumed after TV, VTR, audio system, computer, etc. are turned off using a remote controller or a power switch until a plug is connected. The above waiting electric power is called a waiting electric power or a thief electric power.

[3] Generally, in a waiting mode, consumption electric power occupies about 80% of the entire consumption power in the case of copy machine or video system. In the case of an old type computer monitor, the consumption of power is same when it is used or it is not used.

[4] In Korea, the electric power wasted during the waiting time is above 10% of the commercial use of electric power, reaching to the value of about 760billion won per year. This cost equals to the cost needed when constructing two thermoelectric power plants.

[5] In common companies, the thusly wasted electric power of personal computers and peripherals corresponds to five hours among nine working hours per a day. When it is added to the consumption electric power caused when finishing work or going to bed, the consumption electric power corresponds to above 80% of the total use of electric power. Namely, a large amount of electric power is wasted.

[6] Many people think that a screen saver is a power saving system. However, it is known that the consumption is equally about 150Wh when a screen saver is activated or is not activated.

[7] In a state that the power is turned off when personal computers and peripherals are not used, even when the power is turned off, when the cord is not pulled out, the waiting electric power of 10-30% is continuously consumed. A lot of energy consumption is caused by the waiting electric power consumed as the power cord is not pulled out when personal computers and peripherals are not used and the consumption electric power which is consumed when the above apparatuses remain turned-on. A certain environmental problem may occur, and the life spans of expensive apparatuses may decrease.

[8] As a conventional mechanical apparatus related with a control technology for a power saving adapted to an AC outlet for a power saving apparatus, there is an apparatus capable of braking a waiting electric power by manually setting an electric power supply time and a braking time using a certain mechanical apparatus. When a power supply time and a braking time are set in the above apparatus, it is designed to continuously work within the set time range, so that an applicable field and region are limited.

[9] Among various apparatus which are used in an office, as an apparatus capable of supporting a main apparatus, there are a computer, a printer which supports the computer, a hub which allows computers to be shared, and a scanner which reads images and changes the read images into data.

[10] When a user turns on a switch installed at a front side of a computer body so as to use the computer, a common AC power supplied through an outlet is supplied to a power supply of a body in accordance with a signal of the switch, so that the computer body operates. At the same time, the power is supplied from the power supply to the monitor, so that the user can do a desired work or a certain image work.

[11] In addition, the computer and peripherals are used at home. As an example that the computer is used together with peripherals at home, there is a home theater.

[12] In the case of the home theater, as main apparatus, there is a television set or a projector. As its peripheral, a VCR or a DVD player is connected. Speakers needing an additional power supply are connected with an audio system.

[13] As described earlier, in the case of a main apparatus and peripherals, which support the main apparatus, the electric power should be selectively switched on or off so as to use the peripherals, so that many inconveniences occur.

[14] Almost users turn off only the main apparatus due to the above-described inconveniences, while maintaining the powers of the peripherals turned-on. Therefore, the waiting electric power increases, and the rates of the electric power increase thereby.

[15] So as to overcome the above problems, as shown in Figure 1, a control circuit based on a multi-outlet of Korean patent registration publication No. 10-0316067 is developed. The above control circuit comprises a main tap 1 inserted into a power plug of a main apparatus, a plurality of sub-taps 2 into which a power plug of each subsystem used based on the main apparatus is inserted, and a controller 3 which judges whether the AC is supplied to the main apparatus through the main tap 1 or not and prevents the AC from being supplied to the sub-taps 2 when it is judged that the AC is not supplied to the main apparatus and allows the AC to be supplied to the sub-taps 2 when it is judged that the AC is supplied to the sub-taps 2.

[16] When the AC is supplied to the main apparatus, the controller 3 detects the current of the AC flowing to the main apparatus and judges that the AC is supplied to the main apparatus.

[17] The above-described conventional circuit construction is so complicated, and the electric power is additionally needed so as to operate the circuit. Since a mechanical type relay is used, the life span of the apparatus decreases due to power noises and unstable contact points. Since multiple parts are used, the unit cost for fabrication increases, and competitive power decreases.

[18] As a prior art of the present invention, as shown in Figure 2, there is provided a current induction type switch apparatus of Korean patent publication No. 10-0367930. As shown in Figure 2, there are provided a main terminal 5 for supplying electric power to the apparatuses, and a power supply unit 10 for intermitting the power of the main apparatus connected with the main terminal 5 and controlling the power of the peripherals. Here, the power supply unit 10 induces voltage when load is applied at the main terminal 5, rectifies the induced voltage, generates a trigger pulse at the rectified voltage, generates an AC power and supplies to the main terminal 5. The power supply unit 10 comprises a current detector 11, a rectification/smoothing circuit 12, a zero cross 13 and an output 14.

[19] When an AC 110V/220V power is applied, the current detector 11 induces the applied current and converts the AC into the DC, and the rectification/smoothing circuit 12 generates a constant voltage so that the zero cross circuit 13 can be driven with a pulse type current detected by the current detector 11.

[20] The zero cross circuit 13 is a circuit for trigging the AC output with a constant voltage outputted from the rectification/smoothing circuit 12 and is designed to electrically generate a trigger pulse at near zero. In addition, the main terminal 5 receives a trigger signal from the zero cross circuit 13 and performs a turn-on so as to output the AC. There is further provided a sub-terminal 6, which is connected with the main terminal 5, and applies electric power to the sub-apparatuses and is controlled by the main terminal 5.

[21] As another prior art, according to the power saving type outlet of the Korean patent publication No. 1999-7636 (laid-open date: January 25, 1999), an integrated circuit capable of using a wide range frequency is connected with an outlet of a home electric appliance, so that various home electric appliances having different frequencies can be turned on/off with a remote controller having a certain frequency corresponding to each frequency. Namely, the prior art relates to a power saving outlet.

[22] However, various home electric appliances used at home or in office are not provided with a certain technology capable of turning on/off the power supply unit, which is designed based on a user environment information, a user's power use pattern, a presence of human, etc., so as to fully remove a waiting electric power for an operation of a remote controller and a consumption electric power at the time of no load used by various DC adaptors even when power is turned off in various home electric appliances. Disclosure of Invention Technical Problem

[23] Accordingly, it is an object of the present invention to provide an automatic braking apparatus for a waiting electric power which overcomes the above problems encountered in the conventional art.

[24] It is another object of the present invention to provide an automatic braking apparatus for a waiting electric power which is designed to implement an optimum automatic electric power supply by recognizing a human action environment information, namely, a surrounding light and shade, a use state of remote controller, and daily power consumption pattern, etc. so that the consumption of a waiting electric power can be fully decreased when various electric appliances are turned off and do not work.

[25] It is further another object of the present invention to provide a multi-outlet unit using an automatic braking apparatus for a waiting electric power which includes an infrared ray sensor, a photo electronic sensor, a human body detection sensor and a current sensor which are designed based on the surrounding environments of electric appliances.

[27] To achieve the above objects, in an apparatus of switching electric power of an electric appliance and braking a waiting electric power, there is provided a waiting electric power automatic braking apparatus, comprising a microcomputer which inputs a valid current value, controls an electric power supply and controls a system; a photo electronic sensor which generates a light and shade information so as to recognize a certain user's work environment; a light and shade recognition unit which is formed of a comparator for comparing a light and shade information with a reference value; a human body detection unit which transmits a human presence related signal to the mi- crocomputer using a human body detection sensor for thereby controlling an electric power supply in combination with an electric power control based on the presence of human and the type of a repeated standard electric power; an infrared ray detection unit which recognizes whether a user uses a remote controller-equipped electric appliance by recognizing an infrared ray sensor signal from a remote controller and the presence of a remote control signal from the microcomputer; a current sensor which measures a usual pattern information of the use of electric power; a signal converter which converts the current signal detected by the AC sensor into a valid value; and a current measuring unit formed of an AC adaptor, wherein the light and shade recognition unit, the human body detection unit, the infrared ray detection unit and the current measuring unit are connected with the microcomputer, respectively.

There is further provided an electric power rate measuring unit for measuring and displaying the electric power rate. The waiting electric power braking apparatus is adapted to a multi-outlet.

[31] Preferably, the multi-outlet includes the humidity sensor, the infrared ray sensor, the photo electronic sensor, the human body detection sensor and the current sensor. When the photo electronic sensor, the infrared ray sensor and the human body sensor are all off signals, the waiting electric power is disconnected.

[32] The blue tooth is connected with a television set, an audio set, etc. based on a wireless method.

Advantageous Effects

[33] As described above, in the present invention, it is possible to maximize the electric power saving effects so that the waiting electric power is removed in the case that the electric appliances are not used or it is not time for use of electric appliances.

[34] In particular, the repeating electric power supply time table as well as the surrounding light and shade, the presence of human and the input of the infrared ray signal, which are surrounding environmental elements, are recognized using the sensors using the state information concerning that the user does not use the electric appliances, so that the waiting electric power can be effectively removed.

[35] In addition, the turned on and off states of various electric appliances are auto- matically detected by the waiting electric power braking apparatus according to the present invention which includes the multi-outlet, so that unnecessarily consumed electric energy can be significantly decreased by disconnecting the waiting electric power or supplying the electric power. [36] The present invention provides protection functions, fire prevention effects and electromagnetic wave prevention effects, so that the electric appliances can be protected from over loads or surge.

Figure 12 is a perspective view illustrating a state that an automatic braking apparatus for a waiting electric power is adapted to a multimedia according to the present invention.

[52] As shown in Figure 3, there is shown a construction of an automatic braking apparatus for a waiting electric power according to the present invention, which includes a microcomputer 30 connected with a light and shade recognition unit 20, a power supply unit 40, a human body detection unit 60, a current measuring unit 70, a display unit 80, and an electric power rate display unit 90.

[53] The light and shade recognition unit 20 is a circuit formed of a CDS sensor (photo electronic sensor) for obtaining light and shade information of the current use environment, and an applied circuit of the same. Namely, it is an electric circuit capable of recognizing night time and day time or whether light is fully turned off or not.

[54] Here, the microcomputer 30 includes a control switch port (ml through m6) so as to provide a user input environment such as a manual input of an electric power supply/ disconnection, switches of various operation modes, and reset operation. A low power consumption type switching mode power supply unit 40 is connected with the AC connector 7 so as to supply an operation power of the system.

[55] The human body detection unit 50 is formed of a commonly used human body detection sensor (HIS) so as to recognize the presence of human. Since the logic signals detected by the human body detection sensor HIS changes to H or L based on the presence of human, it is possible to recognize the presence of human. The microcomputer 30, which controls the entire operations of the system, determines the supply of the electric power. When it is judged that there is human, the electric power is supplied. [56] Since almost home electric appliances use remote controller, the infrared ray detection unit 60 is formed of a remote controller receiving module 61, an integration unit 62, and a D-flip flop 63 for a signal process of a remote controller signal.

[57] In the present invention, there are provided a human body detection sensor for detecting the heat from a human body and an infrared ray sensor of a remote controller. The microcomputer having a certain program sets a constant time. The human body detection sensor and the infrared ray sensor operate by a relay output unit. When there is not a moving human, a reverse count starts at a set time. While the reverse count is being performed, when the presence of a moving human is detected, it is detected.

[58] In addition, the current measuring unit 70 includes an AC adaptor 71 connected with an AC power, a current sensor 72 which measures an electric power consumed by an electric appliance connected with the outlet in real time and manages and stores the measured data, a signal shaping bridge circuit 73, and a buffer 74. Here, the power measuring unit 70 is a temporarily operating apparatus and measures the electric power only when the power supply/disconnection relay RLl is turned on. For reference, since the current sensor 72 is formed in a circular structure in which an electric cable passes through the center of the same. When electric power is applied to the electric cable, an electric field is formed around the cable based on Lorentz law. The intensity of the current generated based on the increase and down of the electric field is compared with the reference current. When the current flows more than the reference value, the current sensor 72 is turned on, and when the current flows less than the reference value, it is turned off and transfers a signal to the relay RLl.

[59] The display unit 80 is formed of a LCD so as to display certain information so that the entire operations are informed to the user. Generally, since the consumption electric power of the system according to the present invention needs less than 50OmW, the power saving effect is very significant as compared to the power consumption of the waiting electric power of common home electric appliances.

[60] In the present invention, the microcomputer 30 is connected with the light and shade recognition unit 20, the power supply unit 40, the human body detection unit 50, the infrared ray detection unit 60, the current measuring unit 70, the display unit 80, and the electric power rate display unit 90.

[61] In the present invention, in the user environment, the photo electronic sensor cdsl detects the light and shade information, and the infrared ray sensor D2 detects the input of the infrared ray signal, and the human body detection sensor HSl detects the presence of human, and the current sensor CSI detects the power consumption information in real time.

[62] When the remote controller is turned on, the infrared ray sensor D2 turns on the power, and the photo electronic sensor, the human body detection sensor and the current sensor turn off the power. Namely, in the case that the photo electronic sensor, the human body detection sensor and the current sensor are all low signals at the same time, the power is turned off, and the waiting electric power automatic braking apparatus is turned off. For example, when there is none in the house for a certain reason, at the evening time, the waiting electric power is automatically disconnected for a certain set time period.

[63] In the present invention, the sensors collect information generated, and recognize the time information only when the electric appliance are actually used, so that the AC is supplied or disconnected for thereby minimizing the consumption of the waiting electric power.

[64] The operation of the circuit according to the present invention will be described.

[65] When the electric power is supplied, a signal H is outputted from the relay port

Relay-o of the microcomputer 30, the relay drive transistor Ql is turned on, and the AC control relay RLl is turned on. The AC is supplied to the AC adaptor 71. When the electric appliance is connected with the AC adaptor 71 and operates normally, the AC load current flows. At this time, the current sensor 72 detects the AC load current. Here, the AC current value is not a constant DC value and is measured in purse shapes. The AC of the pulse shape is converted into a valid value of the DC through the bridge rectification circuit 73 of the next block.

[66] The thusly converted value is inputted into the electric power input port (Watt) of the microcomputer 30 through the buffer 74 of the next block and is converted into A/ D in the microcomputer 30 in digital signals, so that the electric power consumption is stored by time elapse. The electric power consumption rate is displayed as an electric power rate based on the mode set of the electric power rate display unit 90. If necessary, the electric power rate may be displayed in the unit of money based on the mode set.

[67] In addition, the light and shade recognition unit 20, which recognizes the surrounding light and shade among the user's environments, is designed to recognize a very dark state, namely, dawn time or a state that the light is fully extinguished because the electric appliance does not operate under the above condition. Since it is not need to keep the fax machine or computer server or refrigerator turned on for 24 hours, the electric power is controlled.

[68] As shown in Figure 4, in the left graph, when light is emitted, the photo electronic sensor cdsl has a resistance value (bright) of below IkW and nearly becomes a short circuit state in which light is not recognized. When the light is not present, the dark resistance increases up to above a few hundreds kW. Namely, the photo electronic sensor electrically becomes an open state, namely, a unlimited resistance state. As seen in the right graph, the voltage value increases above 2.5V in the dark state and decreases in the bright state.

[69] With the above characteristics, as seen on the circuit, when the resistor Rl has IkW, in the dark state, the internal resistance of the photo electronic sensor cdsl becomes a few hundreds kW, so that the photo electronic device output voltage Vcds becomes a supply voltage VCC.

[70]

[71] *Therefore, in this case, the photo electronic device output voltage Vcds is applied at the input (-) of the comparator OPI, and a divide voltage of the reference voltage resistors R2, R3 is applied at the input (+) of the comparator OPI. When the reference voltage Vref is set at 0.5V, the output voltage OPI-output of the comparator OPI becomes H when the photo electronic sensor cdsl has certain brightness, so that the microcomputer 30 can recognize surrounding brightness.

[72] At this time, the brightness can be adjusted by adjusting the variable resistor R3.

Figure 4 is a view illustrating the characteristics of the photo electronic sensor cdsl and the photo electronic device output voltage Vcds. As shown therein, in the case of darkness, the internal resistor of the photo electronic device is a few hundreds kW, and in the case of brightness, the internal resistance of the photo electronic device is a few tens kW.

[73] Figure 5 is a view illustrating an infrared ray receiving and signal process according to the present invention. The infrared ray receiving unit receives a remote control signal since almost electric appliances operate remotely. The user uses it for remotely controlling the electric appliance. When a remote control signal is inputted into the infrared ray receiving unit 61, the infrared ray signal of Figure 5 is detected. This signal is passed through the integration unit 62 and is integrated in an initial signal state. The integration is performed for the reason that it should operate with respect to any kinds of user s remote controllers irrespective of the code analysis of the remote control signal. Namely, it responses to any kinds of remote controllers. The thusly integrated signal (initial signal) is inputted into the D-flipflop 63 of the next block and is finally converted into the IR signal shown in the lower most portion of Figure 5. The signal is inputted into the infrared ray input port IR of the microcomputer 30. Here, the D-flipfop 63 is adapted for the reason that once a remote control signal is inputted, the next remote control signal is neglected.

[74] Figure 6 is a view illustrating a time-based electric power consumption and a standard electric power supply state according to the present invention. In the circuit of Figure 3, the current sensor 72 and the surrounding interface circuit measure the electric power. The time-based electric power consumption measured by the microcomputer 30 is shown in the graph. Here, the valid electric power Prms can be calculated by multiplying the measured AC valid current lrms with the 220V valid AC voltage value Vrms in the following equation.

[75]

[76] Prms = 220Vrms * lrms (measured value)

[77]

[78] The microcomputer recognizes the daily repeated electric power consumption and stores the great common divisor, namely, the value that the electric power time range is most wide and uses the stored value as a standard electric power supply time table. The above standard electric power supply table is shown in the graph of Figure 6. Here, the power on/off time and the time of the standard electric power supply are set in the microcomputer 30. A certain margin may be preferably provided at the left and right sides.

[79] Figure 7 is a view illustrating an electric power supply state based on the input of an infrared ray signal according to the present invention. There is shown a change of the electric supply in addition to the known standard electric power supply table when a remote control receiving signal is present. When the infrared ray signal is inputted at least one time, the electric power supply starts at the time of the input of the infrared ray signal based on the time table of the standard electric power supply.

[80] Namely, the electric power supply stops at the time when the final electric power disconnection time becomes same as the standard electric power supply condition. The electric power supply is determined based on the remote control signal input in consideration of the abnormal use of the electric power, not the standard electric power supply, when the electric appliance connected with the remote controller is used.

[81] Figure 8 is a view illustrating an electric power supply state based on a photo electronic device (cds) input signal according to the present invention. When the surrounding brightness becomes high under the user s environment at the standard electric power supply time (power connect time), it is estimated that the user will use the electric appliance (the upper most figure), and the electric power supply is resumed.

[82] Namely, as seen in the graph, when it is recognized that light is inputted from the photo electronic device cds, the microcomputer 30 gets ready so as to supply electric power irrespective of the standard electric power supply state. At the time of the electric power supply time (04 to 22) at the lower most portion, since the electric power is not connected (namely, waiting electric power is present), when the power is turned on using the remote controller, the photo electronic sensor is turned on. Namely, the above construction is designed so as to prevent a problem that the electric power is not supplied even when the remote controller is turned on when there is not waiting electric power at night.

[83] Figure 9 is a view illustrating an electric power supply state based on the input of a current sensor 72 according to the present invention. The apparatus operates only when the current sensor 72 operates at the electric power supply start and the disconnection time based on the surrounding brightness under the work environment in a state that the standard electric power system is neglected based on the mode switch SW8 of the microcomputer 30. The above construction corresponds to an option that almost electric appliances are used when it is very dark. Namely, the current sensor operates at the electric power supply time (power connect time) shown at the lower most portion of Figure 9. It is known that certain electric power consumption (Pl through P3) occurs as a certain electric appliance is used as shown in the upper most portions in the figure.

[84] Figure 10 is a view illustrating an electric power supply state based on an input of a human body detection sensor (HSl) signal according to the present invention. The human body detection sensor HS 1 is designed to recognize a certain wavelength based on a heat temperature radiated from a human body when a human moves. This sensor is generally installed at a porch. In the present invention, the human body detection sensor is adapted so as to recognize the presence of the human, so that the electric power supply starts. The lower portion of the graph represents the electric power supply time table (power connect time). This table is set at the microcomputer 30, so that the electric power supply starts when the presence of the human is detected in cooperation with the standard electric power supply system.

[85] When the surrounding portions are dark, and no infrared signals and human are detected, namely, when the photo electronic sensor, the human body detection sensor and the infrared ray sensor all output low signals at the same time, the waiting electric power braking apparatus according to the present invention operates based on the standard electric power time table. Therefore, in the present invention, it is possible to minimize any inconveniences which may occur due to abrupt disconnection of electric power, while considering various surrounding environment elements.

[86] Figure 11 is a perspective view illustrating a state that the automatic braking apparatus for a waiting electric power is adapted to a multi-outlet according to the present invention.

[87] Here, the multi-outlet 100 adapting the waiting electric power automatic braking apparatus according to the present invention includes a controller 200, and a plurality of outlets 300. An electric power cable L is connected with an outlet body H.

[88] The controller 200 includes a blue tooth 210 which is a communication apparatus, a humidity sensor 240, and a current sensor 230 and is connected with the infrared ray sensor D2, the photo electronic sensor cdsl and the human body detection sensor HSl. An audio connection jack 220 connecting an external television set, audio system, etc. is attached to the controller 200. [89] The operation of Figure 11 will be described. When a certain button of the remote controller used at home is pressed, the outlet 300 is turned on, and the electric power is supplied to the electric appliance. In this case, the infrared ray sensor D2 manages the operation of the circuit.

[90] When the photo electronic sensor, the human body sensor and the current sensor are all off signals, the multi-outlet 100 is automatically turned off. Among the above three sensors, at least one sensor receives an on signal, the multi-outlet is not turned off.

[91] For reference, the DC adaptor according to the present invention supplies electric power of 3.3V. The humidity sensor 240 automatically adjusts the operation of a moisturizer. The audio connection jack 220 is connected with the television set or the audio jack and transfers audio signals based on a wireless method using a wireless system.

[92] Figure 12 is a perspective view illustrating a state that a waiting electric power automatic braking apparatus is adapted to a multimedia system according to the present invention. As shown therein, the multi-outlet 100 is connected with the audio system, television set and the speakers. The blue tooth 210 installed in the controller 200 of the multi-outlet 100 transfers audio signals in stereo based on a wireless method. It is possible to change the arrangements of speakers in various forms in combination with the blue tooth technology. Recently, the use of home theater increases, so that excellent sound quality speakers can be achieved with the use of decreased power consumption according to the present invention.
