The power supply unit 9 includes a plurality of outlets for supplying power to the electric product 10. FIG. 2 is a configuration diagram of the numeric keypad 11 provided in the remote control device 2, and FIG. 3 is a block diagram of a control system in the remote control device 2. FIG. 4
FIG. 5 is an example of information output as an infrared instruction signal, and FIG. 5 is a block diagram showing a configuration of a main part of the power supply device main body 1.

The operation of this embodiment will be described below with reference to FIGS. First, when the user presses the numeric keypad 11 in the remote control device 2 to indicate the number of the electric product, and then presses the on key 12 or the off key 13 to turn on or off the power supply of the electric product, the remote control device 2
The instruction content is acquired by the remote controller control unit 15 inside, and information as shown in FIG. 4 is emitted from the light emitting unit 16 as an infrared instruction signal under the control of the remote controller control unit 15. 4A shows information for instructing power on of the second electrical product, and FIG. 4B shows information for instructing power off of the third electrical product. The infrared instruction signal blinks such information, for example. This is converted into a bit string. When the infrared instruction signal as described above is received by the light receiving section 3 of the power supply device main body 1, the light receiving section 3 converts the received infrared instruction signal into an electric signal and provides the electric signal to the code decoding section 4. 4
, The code information as shown in FIG. 4 is reproduced.
The reproduced code information is provided to the arithmetic unit 6 via the control unit 5, and the arithmetic unit 6 interprets what meaning the input code information has. That is, for example, in the case of the code information as shown in FIG. 4A, it is interpreted that the power-on of the second electrical product has been instructed, and the interpretation result is notified to the control unit 5.

The CPU 21 in the control unit 5 (hereinafter, refer to FIG. 5) sets data to the port 22 according to the notification. That is, if only the second electrical product (connected to the outlet 25b) is turned on, the output terminal D
Set so that only 2 becomes High level. Therefore, a switch (for example, a relay or a semiconductor switch) 24b is turned on by the driver 23b through the port 22, and the AC power input to the power supply unit 9 from the AC input terminal 26 is output only to the outlet 25b, and
Power is supplied to the second appliance. In the embodiment of the configuration of FIG. 1, the voltage output from the remote control device 2 to the outlet is specified, and the power supply unit 9 can supply the power of the specified voltage together with the power-on operation. is there. In this case, the power supply voltage to be supplied to each electrical product 10 may be set in the storage unit 7 in advance, and such a function will be described below.

FIG. 6 is a diagram showing an example of instruction information issued from the remote control device 2 for setting a voltage, and FIG. 7 is a diagram showing an example of a voltage table created in the storage section 7 of the power supply device main body 1. FIG. 8 is a block diagram showing another configuration of the main part of the power supply device main body 1. Hereinafter, an embodiment in which the power supply voltage is specified will be described with reference to FIGS. 6, 7, 8, and the like. FIG.
Is the instruction information issued from the remote control device 2 to set the voltage. For example, (a) shows that the voltage of the first electric product is 100 V, the voltage of the second electric product is 50 V, and the voltage of the third electric product is This means setting the voltage to 100V. In order to specify the contents of (a), first, 1 is input by the ten keys 11, then the set key 14 is pressed, and 100 is input by the ten keys 11. The same applies to the settings of the second and third electric devices. When the receiving unit 3 receives the infrared instruction signal, which is a bit string of the instruction information as shown in FIG. 6, the arithmetic unit 6 interprets the content, and the control unit 5 obtains the same as in the above-described embodiment. A voltage table as shown in FIG. 7 is created in the storage unit 7. When the voltage value is other than 100 V, the operation unit 6 calculates an off-timing value (described later) and sets it as shown in FIG.
The off-timing value may be calculated by the remote operation device 2 or another device, and the off-timing value may be directly transferred from the remote operation device 2 to the power supply device main body 1.

After such a voltage setting is performed and the set voltage value is displayed on the display unit 8, when the light receiving unit 3 of the power supply device main body 1 receives the instruction information shown in FIG. The CPU 21 in the control unit 5 acquires the voltage value of the second electrical product, that is, a value of 50 V, from the voltage table in the storage unit 7. Further, since the acquired voltage value is other than 100 V, the CPU 21 further acquires an off-timing value relating to the second electric appliance. Note that the off timing is point b shown in FIG. 9, and the off timing value is
This is the time from the ON timing a to the point b. That is, in order to realize a supply voltage of 50 V, power is supplied only during the period indicated by hatching in FIG. In FIG. 9B, 80
The off-point b for realizing the supply voltage of V is shown. As described above, while the off-timing varies depending on the voltage value, the on-timing a is always the zero cross point of the AC voltage waveform.

FIG. 8 is a block diagram of a main part of the power supply device main body 1 for realizing the voltage control as shown in FIG. As shown, the power supply unit 9 includes a step-down transformer 27 and a zero-cross detection circuit 28, and the control unit 5 includes a timer 29. When the zero-cross point of the AC voltage stepped down by the step-down transformer 27 is detected by the zero-cross detection circuit 28, the zero-cross detection circuit 28
The CPU 21 sets an off-timing value (for example, 5 ms) in the timer 29 and starts the timer 29 in response to an interrupt from the CPU 29. At this time, the CPU 21 sets D2 of the port 22 to High level, and power is supplied to the second electrical product 10. The timer 29 starts measuring 5 ms at the time of activation, and when the time elapses, causes the CPU 21 to generate an interrupt. Due to the interruption, the CPU 21 sets D2 of the port 22 to Low level, and the power supply to the second electrical product is stopped. Hereinafter, power supply of an effective voltage of 50 V is realized similarly. Thus, according to this embodiment, power supply on / off to an arbitrary electric product among a plurality of electric products can be operated by one remote control device. Further, the power supply voltage to be supplied can be set arbitrarily. Note that a configuration in which power supply on / off of one electric product is remotely controlled is also possible. In this case, there is no need for a means for specifying an electrical product in the remote control device, and no means for selecting an outlet for supplying power in the power supply device main body.

31, a storage unit 32 for storing instruction information and the like, a timer 33 for measuring the passage of the designated time, and the like.
The operation unit is newly provided with a timer key 17. Then, the instruction information is transmitted, for example, after the designated time. Therefore, when the remote control unit 15 recognizes that the timer key 17 has been pressed, the input time is set in the timer 33 and the timer 33 is activated. The instruction information input after the set time is stored in the storage unit 32. Thereafter, the timer 33 starts counting time, and upon detecting the elapse of the set time, generates an interrupt to the CPU 31 and outputs
U31 reads the instruction information stored in the storage unit 32, and transmits the instruction information to the power supply device main body 1 as in the first embodiment. In addition, instead of indicating the time until the call, it is also possible to configure so as to indicate the call time. In such a configuration, the timer 33 must include a clock circuit that outputs the current time, a register that stores the transmission time, and a comparison circuit that compares the current time with the transmission time. Then, after the input transmission time is stored in the register, when a match signal is output from the comparison circuit, the match signal is used as an interrupt signal and the CPU 31
And power on / off can be executed at a desired time.

It should be noted that the power supply device main body 1 has the same functions as the information device interface unit 34 and the remote control controller 15 without the remote control device 2 and interprets the instruction information from the information device in the power supply device body 1. It is also possible to process. According to this embodiment, for example, in a factory or the like in which a computer performs centralized control of various devices, it is possible to perform extremely fine power control, and thus to save power.
