  As a standby power reduction system for reducing standby power of electric devices such as a television and an air conditioner, a system having an intelligent tap table has been proposed (for example, see Patent Document 1). This intelligent tap table has switch means for supplying and stopping power supply to electrical equipment (for example, a television), and a power control unit for controlling the switch means, and a power-on signal is input to the intelligent tap table. Then, the power control unit turns on (closes) the switch unit based on the power-on signal, and power from the power source (for example, an indoor power line) is supplied to the electric device. In this standby power reduction system, whether or not there is a person is detected by a human sensor, and when it is detected that there is no person, the control unit generates an off control signal based on the detection signal from the human sensor, The off control signal is sent to the electrical equipment and intelligent tap table. On the electric device side, the electric device is turned off based on the off control signal. Also, on the intelligent tap table side, the switch means is turned off (opened) based on this off control signal, thereby stopping the power supply to the electrical equipment, and thus using the detection signal of the human sensor. Standby power consumption can be reduced.

  In this embodiment, a first controller 32 for controlling the electric device 2 (for example, a television) is further provided, and a second controller 34 for controlling the power supply unit 8 is also provided. The first controller 32 includes a signal transmission unit 36, a state determination unit 38 and an operation control signal generation unit 40. The signal transmission means 36 transmits an infrared signal as will be described later, and the state determination means 38 determines the state of the electrical device 2 based on the detection signal of the current detection sensor 28 of the power supply unit 8, and the operating current flows. When the electric device 2 is in operation, it is determined that the electric device 2 is in an operating state. When the standby current is flowing, it is determined that the electric device 2 is in a standby state. Determine. Further, the operation control signal generating means 40 generates an operation signal, a standby signal, a non-operation signal, etc. as described later.

  The first controller 32 further includes timer means 42 and memory means 44. The timer means 42 measures various predetermined times described later. In the memory unit 44, the relationship between the determination state of the state determination unit 38 and the control signals (operation signal, standby signal, and non-operation signal) generated by the operation control signal generation unit 40 is registered as a control map. .

  In this embodiment, the first controller 32 is provided with infrared transmission means 46 (which constitutes the first infrared transmission means) and infrared reception means 48 (which constitutes the first infrared reception means). The first infrared transmission means 46 sends an infrared signal toward the second infrared reception means 16 of the electrical device 2, and the first infrared reception means 48 receives the infrared signal from the second infrared transmission means 27 of the remote controller 4. Receive.

  The second controller 34 includes a connection signal generating unit 45 that generates a connection signal and a connection disconnection signal generating unit 47 that generates a connection disconnection signal. When this connection signal is sent to the relay means 30, the relay means 30 is closed, and power is sent to the electrical equipment 2 through the power supply system 6. When the disconnection signal is sent to the relay unit 30, the relay unit 30 is opened, and the supply of power through the power supply system 6 is stopped.

  The first control controller 32, the second control controller 34, and the remote controller 4 are further provided with a communication module for communicating (that is, transmitting and receiving) various signals. The first controller 32 is provided with a first main communication module 50, the second controller 34 is provided with a second main communication module 52 that communicates with the first main communication module 50, and The remote controller 4 is provided with a sub communication module 54 (which constitutes a first sub communication module) that communicates with the first main communication module 50. As the first and second main communication modules 50 and 52 and the sub communication module 54, for example, a wireless network module known per se can be used.

  Next, with reference mainly to FIG. 2 and FIG. 3, the control when the power switch 18 of the remote controller 4 is input will be described. When the power switch 18 of the remote controller 4 is input, the process proceeds to step S1 where an input signal (that is, a power input signal) from the remote controller 4 is sent to the first control controller 32 via the sub-communication module 54 and the first main communication module 50. To the second control controller 34 via the first main communication module 50 and the second main communication module 52. Further, this input signal (infrared power input signal) is sent to the first controller 32 via the second infrared transmission means 27 and the first infrared reception means 48.

  When the power input signal is sent to the second controller 34 in this way, the current detection sensor 28 of the power unit 28 is connected to the power supply system 6 (specifically, the power supply system 6 (specifically, the power supply system) based on the signal from the second controller 34. The current flowing through the cord 14) is detected (step S2), and the detection signal of the current detection sensor 28 is sent to the first controller 32 via the second controller 34, the second main communication module 52, and the first main communication module 50. Be sent.

  Thus, when the detection signal from the current detection sensor 28 is supplied, the state determination unit 38 of the first control controller 32 determines the state of the electrical device 2 (for example, a television) (step S3). That is, when the current detection sensor 28 detects an operating current, the state determination unit 38 determines that the electrical device 2 is in an operating state and detects a standby current (or a non-operating current whose current is zero). The state discriminating means 38 discriminates that the electric device 2 is in the standby state (or inactive state).

  If it is determined that the electrical device 2 is in the operating state, the process proceeds from step S4 to step S5, and the standby operation of the electrical device 2 is performed. That is, the operation control signal generation means 40 generates a standby signal (step S6), and based on this standby signal, the input signal (infrared power input signal) received by the signal transmission means 36 from the remote controller 4 is the first infrared transmission means. 46 and the second infrared receiving means 16 are sent to the electric device 2, and the electric device 2 enters a standby state based on the supplied infrared power input signal (step S7).

  Then, when a predetermined time elapses after entering the standby state (for example, set to about 5 to 20 minutes and the timer means 42 counts the predetermined time), the process proceeds from step S8 to step S9, and the first controller 32 The operation control signal generation means 40 generates an operation stop signal (step S9), and this operation stop signal is sent to the second controller 34 via the first main communication module 50 and the second main communication module 52. . Then, the disconnection signal generation means 47 of the second controller 34 generates a disconnection signal based on the operation stop signal (step S10), and the relay means 30 is opened based on the connection disconnection signal. As a result, the supply of electric power to the electric device 2 through the electric power supply system 6 is stopped (step S11), and the electric device 2 becomes inoperative. As described above, after the standby state of the electrical device 2 is continuously maintained for a predetermined time, the power consumption becomes zero (zero) after being in a non-operational state, so that the standby power can be reduced to save energy. .

  When it is determined that the electric device 2 is in the standby state, the process proceeds from step S4 to step S14 through step S13, and the operation of the electric device 2 is performed. When the power switch 18 of the remote controller 4 is input in the standby state in step S7, the process proceeds to step S14 through step S8, step S12, step S2, step S3, step S4, and step 13. At this time, the operation control signal generation unit 40 generates an operation signal (step S15), and based on this operation signal, the input signal (infrared power input signal) received by the signal transmission unit 36 from the remote controller 4 is transmitted to the first infrared. The electric device 2 is supplied to the electric device 2 via the means 46 and the second infrared receiving device 16, and the electric device 2 is activated based on the supplied input signal (step S16).

  When it is determined that the electric device 2 is in an inoperative state, the process proceeds from step S4 to step S13 through step S13, and the operation of the electric device 2 is performed. That is, the operation control signal generating means 40 generates an operation signal (step S17), and this operation signal is sent to the second controller 34 via the first main communication module 50 and the second main communication module 52. Then, the connection signal generation means 45 of the second controller 34 generates a connection signal based on this operation signal (step S19), and the relay means 30 is closed based on this connection signal, thereby Electric power is supplied to the electrical equipment 2 through the supply system 6 (step S20).

  At this time, the operation control signal generation unit 40 generates an infrared standby signal (step S21), and the generated infrared standby signal is transmitted through the first infrared transmission unit 46 and the second infrared reception unit 16 to the electrical device 2. And the electric equipment 2 enters a standby state (step S22). Subsequently, the operation control signal generation unit 40 generates an infrared operation signal (step S23), and the generated infrared operation signal is sent to the electrical device 2 via the first infrared transmission unit 46 and the second infrared reception unit 16. Then, the electric device 2 is activated based on the infrared activation signal (S16). When the power switch 18 of the remote controller 4 is input while the power supply to the electric device 2 is stopped in this way, the electric power is supplied to the electric device 2 and further automatically after the electric device 2 enters the standby state. Therefore, even when the power supply is stopped, the electric device 2 can be put into an operating state as required by simply performing an input operation on the remote controller 4.

  In this embodiment, when the power switch 18 of the remote control 4 is input and operated in the power supply stop state, the electric device 2 is automatically activated after being put into a standby state. Instead, when the power switch 18 is input, the electric device 2 is set in a standby state, and then the power switch 18 is input again, based on the input signal (infrared power input signal) from the remote controller 4. May be put into an operating state as described above.

  Next, a standby power reduction system according to the second embodiment will be described with reference to FIGS. In the second embodiment, a human sensor for detecting a person and a configuration related thereto are added. In this embodiment, members substantially the same as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  4 and 5, in the second embodiment, a human sensor 102 is provided in association with the electric device 2, and the human sensor 102 may be attached so as to be integrated with the electric device 2. Or you may make it attach to the room in which the electric equipment 2 was installed. The human sensor 102 is provided with a second sub-communication module 104, and a detection signal from the human sensor 102 is sent to the first controller 32A via the second sub-communication module 104 and the first main communication module 50. Be sent.

  In relation to providing the human sensor 102, the first controller 32A further includes a human presence determination unit 106. The human presence determination means 106 determines that there is a person based on the detection signal when the human sensor 102 detects a person, and no person based on the detection signal when the human sensor 102 does not detect a person. Is determined. Other configurations of the second embodiment are substantially the same as those of the first embodiment described above.

  In the second embodiment, the control in the operating state of the electric device 2 is as follows. Referring to FIG. 6 together with FIG. 5, in the operating state of the electrical device 2, human detection is performed by the human sensor 102 (step S31), and the detection signal from the human sensor 102 is sent to the second sub-communication module 104 and It is sent to the first controller 32A through the first main communication module 50.

  When the detection signal from the human sensor 102 is sent in this way, the human presence determination means 106 of the first controller 32A determines whether or not there is a person. The process proceeds to step S33 via S32, and the operation state of the electric device 2 is continuously performed on the assumption that it is not necessary to perform the energy saving operation. Then, when the power switch 18 of the remote controller 4 is input in such an operating state, the process proceeds from step S34 to the power switch 18 operation routine of the remote controller 4, and in this routine, for example, the operation shown in FIG. To be carried out.

  If the person presence determination unit 106 determines that there is no person, the process proceeds from step S32 to step S35, and the state in which there is no person continues for a first predetermined time (for example, set to about 10 to 20 minutes, and the timer unit 42). When the first predetermined time is counted), the operation control signal generating means 40 generates an infrared standby signal (step S36). Thus, the infrared standby signal is sent to the electrical device 2 via the first infrared transmission means 46 and the second infrared reception means 16, and the electrical device 2 enters a standby state based on the infrared standby signal (step). S37).

  Even in this standby state, the human sensor 102 detects a person (step S38), and a state in which the human sensor 102 does not detect a person continues for a second predetermined time (for example, set to about 5 to 20 minutes). When the timer means 42 measures this second predetermined time), the process proceeds from step S39 to step S41 through step S40, and the operation control signal generation means 40 of the first control controller 32A generates an operation stop signal (step S41). ), The operation stop signal is sent to the second controller 34 via the first main communication module 50 and the second main communication module 52. Then, the disconnection signal generating means 47 of the second controller 34 generates a disconnection signal based on this operation stop signal (step S42), and the relay means 30 is opened based on this disconnection signal, As a result, the supply of power to the electrical equipment 2 through the power supply system 6 is stopped (step S43). As described above, when the state in which there is no person continues for the first predetermined time, the electric device 2 enters the standby state, and when the state in which there is no person continues in the standby state for the second predetermined time, the supply of power is stopped and the electric device is stopped. Since 2 becomes inactive, standby power can be reduced as described above.

  Further, when the human sensor 102 detects a person in the standby state of the electric device 2, the process proceeds from step S39 to step S44, and thus the person is detected, but the state where the power switch 18 of the remote controller 4 is not input is the third state. If it continues for a predetermined time (for example, set to about 5 to 20 minutes and the timer means 42 measures this third predetermined time), the process proceeds from step S44 to step S41 through step S45, and steps S2 and S43 are executed. Thus, the supply of electric power to the electric device 2 is stopped. When the power switch 18 of the remote controller 4 is input in this standby state, the routine proceeds from step S44 to a routine for operating the power switch 18 of the remote controller. In this routine, for example, the operation shown in FIG. 3 is executed.

  In the second embodiment, the control of the electric device 2 in the standby state is as follows. Referring to FIG. 7 together with FIG. 5, in the standby state of electric device 2, human detection by human sensor 102 is performed (step S51), and steps S52 to S58 based on the detection signal of human sensor 102 are performed. The control based on the detection signal (the control in step S52 to step S58) is substantially the same as the control in step S39 to step S45 in the flowchart of FIG. 6, and therefore the control will be described.
