(Embodiment 1) A first embodiment of the present invention will be described. FIG. 1 is a block diagram showing the configuration of this embodiment. The control device of the device according to the present embodiment includes a child device 30 and a parent device 35. Although a plurality of slave units 30 may exist, the description will be made here assuming that one slave unit is provided. The slave unit 30 relays electricity from the commercial power supply 11 and supplies it to the air conditioner 12, which is an example of a device connected to an AC power supply. In addition, child unit 30
Is a current measuring unit 13 composed of a current sensor or a current transformer for measuring a current flowing through the air conditioner 12.
An electric quantity detection unit 14 for measuring the power consumption of the air conditioner 12, a circuit power supply 17, a microcomputer 31
And a control output unit 22 including a terminal block, a connector, a lead wire, and the like, a human body sensor 23, a communication unit 32 including a transmission unit and a reception unit, and an antenna 33.
In the description of the embodiment, the description of the signal input means is omitted in the figure, but it is assumed that the human body sensor 23 is connected via the signal input means. The electric quantity detecting means 14 includes a voltage detecting means 15 such as a transformer and a current measuring means 15 including a circuit for processing a current value based on a value measured by the current measuring unit 13. The circuit power supply 17 is a power supply circuit that supplies power to a circuit in the slave 30. The microcomputer 31 includes a storage unit 19 and a power calculation unit 21. The master unit 35 includes a microcomputer 36 having a storage unit 37 and a control unit 38, a communication unit 39 including a transmission unit and a reception unit, and an antenna 40.

The operation will be described below. Air conditioner 12 is O
When in the N state, the current measurement unit 13 senses the current consumption of the air conditioner 12 and transmits the result to the current detection unit 15, and the current detection unit 15 transmits the current value to the microcomputer 31. On the other hand, the voltage detecting means 16 measures a voltage value of a commercial power supply or the like supplied to the slave unit 30 and transmits the voltage value to the microcomputer 31 as a voltage value applied to the air conditioner 12. These microcomputers 31
The power calculation means 21 calculates the power consumption of the air conditioner 12 based on the data transmitted to the air conditioner 12. The raw data of the power consumption, current, and voltage of the air conditioner 12 calculated by the power calculation unit 21 and the result calculated by the control unit 20 based on these data are as follows.
The microcomputer 3 via the communication means 32, the antenna 33, the antenna 40 of the base unit 35, and the communication means 39;
6 and transmitted to the storage means 37 and the control means 38. The storage means 37 stores data. The control means 38 detects the transition of the time zone in which the air conditioner 12 is used based on the transmitted time transition of the power consumption of the air conditioner 12 and the like, and based on the result, these air conditioners 12 Predict what time of day it will be used. That is, for example, in this home, although there is some temporal variation every day, the time period during which the air conditioner 12 is used is from 6:00 to 8:00, which is a breakfast time period, and from 11:00 to 13:00, which is a lunch time period, on weekdays. At time, it is detected from the time transition of the power consumption that the power consumption can be collected from 17:00 to 22:00, which is the time zone of dinner preparation, dinner time, and group gathering, and it is predicted that the power consumption will be continued in this time zone. As a result, the control means 38 turns on the control signal for controlling the air conditioner 12 in the time period in which it is predicted that the air conditioner 12 will be used, and conversely, controls the air conditioner 12 in the time period in which it is predicted that the air conditioner 12 is not used. The control signal is determined to be OFF, and the content of the control signal is transmitted to the microcomputer 31 via the communication means 39, the antenna 40, the antenna 33 of the slave unit, and the communication means 32. The microcomputer 31 transmits the transmitted control signal for controlling the air conditioner 12 to the control output unit 22.

As an example of specific processing for determining the control signal of No. 2,
Assuming a certain variable α, α−1 is set as a new α during a time period when the air conditioner 12 is not used, and α + 5 is set as a new α during a time period when the air conditioner 12 is used. As a result, when α becomes an arbitrary value β or less, it is predicted that the possibility of use of the air conditioner 12 is low in this time zone, and the air conditioner 12 is turned off.
A control signal for turning on the air conditioner 12 is output. When the control signal becomes equal to or more than β, the control signal for turning on the air conditioner 12 is output to the air conditioner 12 on the assumption that the possibility of use of the air conditioner 12 is high in this time zone. At this time, needless to say, α and β can be arbitrarily determined by numerical values, functions, and the like. In addition, when an extremely characteristic air conditioner use pattern can be detected, for example, depending on the day of the week or the season, a more accurate prediction can be made by recognizing this and performing a prediction.

As described above, the slave unit 30 and the master unit 35 of the controller of the apparatus of the present embodiment determine the transition of the use time of the air conditioner 12 from the transition of the power consumption of the air conditioner 12, and from this result, Predict the future use time zone.
Based on this result, by outputting a control signal for turning on / off the air conditioner 12, unnecessary power consumption during a time period when the air conditioner 12 does not need to be used is eliminated, thereby realizing power saving.

In the present embodiment, the slave 30 is a human body sensor 23.
The air conditioner 12 is controlled based on the information detected by. Specifically, the human body sensor 23 determines whether or not there is any person in the detection area, transmits the same to the microcomputer 36 of the master unit in the same manner as the power information, and sends the information to the control unit 38 and the storage unit 37 in the microcomputer 36. introduce. Storage means 37
Accumulates this information, and the control means 38 determines a control signal for controlling the air conditioner 12 based on this information. Control means 3
8 detects, based on the data from the human body sensor 23, the temporal transition of the presence / absence of a person in the area up to now,
Based on this result, it is predicted in what time zone there is a high possibility that a person is in the area. As a result, the control unit 38 outputs a control signal such as turning off the air conditioner 12 from the control output unit 22 or setting a power saving operation in a time period when there is a high possibility that no person is present in the area. The air conditioner 12 operates based on the control signal. As described above, the child device 30 and the parent device 3 of the device control device of the present embodiment are
No. 5 realizes power saving by estimating the presence / absence time of a person and eliminating unnecessary power consumption such as saving power during a time when no people are present. It is needless to say that the control signal is not limited to a simple ON / OFF command, and may transmit various information such as a change in set temperature and a timer setting. In addition, as a method of calculating the power consumption of the air conditioner 12, a calculation such as multiplying the current detection unit 15 and the voltage detection unit 16 by a value for each minimum time, such as several microseconds, is performed, and a method of integrating the unit time is used. Needless to say, you can ask. Needless to say, the voltage detection means is not provided as the electricity quantity detection means, and the output of the pseudo electricity quantity detection means may be based on the output of the current detection means. It goes without saying that the communication between the master unit 35 and the slave unit 30 is not limited to wireless communication, but may use any communication medium such as power line carrier communication or dedicated line communication.

In this embodiment, the slave unit is provided outside the air conditioner 12. However, the slave unit may be built in the air conditioner 12, so that the installation can be easily performed. The slave unit is connected between a device connected to the commercial power supply such as an air conditioner and the commercial power source.
