Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home appliance control device.

[0002]

2. Description of the Related Art Conventionally, electronic devices in a general house are usually controlled by a user using an operation unit of each device itself or a dedicated remote control attached to the device. In a home automation (HA) system that is expected to be widely used in the near future, it is common to provide an operation unit that collectively operates those devices, and that the operation unit is operated or automatically controlled by a user. . In the HA system, the controller and each device are basically connected by wire.

[0003]

However, in the case of the HA system, it is almost always used in a newly-built house, and a considerably large-scale construction is required for a house intended for renovation or when a system is to be added later. .

[0004]

Means for Solving the Problems and Action / Effects The invention according to claim 1 made in order to solve the above problems,
In a control device having means for transmitting data for controlling functional products in a house by radio waves, means for transmitting radio waves for human body detection, means for generating a signal for transmission as radio waves to the outside, A human body operation state grasping unit, comprising: means for receiving a signal transmitted from the outside as a radio wave; and signal generation means for obtaining a difference between the transmission signal and the frequency of the reception signal and generating a signal corresponding to the difference. Is built-in. According to the present invention, each device can be controlled in accordance with the operation state of the human body, so that unnecessary power can be saved in a place where there are no people.

[0005] The invention according to claim 2 is characterized in that the means for transmitting data by radio waves and the means for generating a signal to be transmitted to the outside as radio waves are also used. According to the present invention, since a radio signal carrying information for controlling a device and a sensor signal for detecting a human body for grasping the state of a human body are also used, one unit can share two functions, and cost is reduced. Can be reduced.

According to a third aspect of the present invention, in the equipment control device in a house, a means for processing data transmitted from a product in the house is added to a means for receiving a signal transmitted as a radio wave from outside. It is characterized by having done. ADVANTAGE OF THE INVENTION According to this invention, since the sensor signal for human body detection which grasps the state of a human body, and the radio signal which carried information, such as driving conditions, from an apparatus can be processed without providing another unit, the size of a unit can also be reduced. Cost reduction can also be realized.

The invention according to claim 4 is characterized in that the frequency of the transmitting means is 2.45 GHz to 12 GHz. According to the present invention, the frequency of the transmitting device is set to 2.45.
By setting the frequency to GHz or higher, it becomes possible to extract a Doppler signal for detecting a motion of a human body. In other words, if it is less than this, an accurate Doppler signal cannot be obtained. Further, by setting the frequency to 12 GHz or less, the signal itself is hardly attenuated due to the influence of water vapor and dust in the air, and as a result, accurate detection can be realized.

According to a fifth aspect of the present invention, in the control device for equipment in a house, a plurality of human body operation state grasping units are provided. According to the present invention, a microwave is used for the human body detecting means, and a transmitted radio wave is reflected from a measured object (here, a person), and a signal of a difference from the returned radio wave is processed to estimate a state of the human body. Therefore, if the human body operation state grasping unit is in the moving direction of the human body, a more accurate operation state can be grasped. The device that controls the device is in one place, and if the human body operation state grasping unit is arranged in a portion where people come and go, it is possible to realize an advanced HA system.

According to a sixth aspect of the present invention, in the control device of the equipment in the house, there is provided means for detecting a human abnormality from the human body operation state grasped by the human body operation state grasping unit. According to the present invention, even if it is determined that a person is present, if there is no evidence of movement for a long period of time, it is assumed that something is abnormal for some reason, and an alarm is sounded or the security company is notified. Measures such as reporting can be taken.

Embodiments of the present invention will be described below in detail with reference to the drawings.

Embodiment 1 FIG. 1 is a structural diagram of a wireless system in a house. FIG. 2 is a detailed diagram of the radio wave sensor. First, the configuration will be described. In a general house, there are various electric appliances including home appliances, and when each of them is controlled by one control box 1, data is exchanged wirelessly. Further, the control box 1 can transmit and receive radio waves for detecting a human body. The radio wave sensor 12 includes a transmitting unit 13 and a receiving unit 14.
The transmission unit 12 has a function of transmitting radio waves for detecting a human body and data for controlling devices. The receiving unit 13
Radio waves for human body detection and data for device control can be received.

Next, the operation will be described. Control box 1
Inside, there is a radio wave sensor 12, which transmits a radio wave for human body detection and data for device control alternately from the transmission unit 13 of the radio wave sensor 12, and communicates the state of human body operation and information with the device. ing. The radio wave sensor 12 constantly or at regular intervals checks the operating state of a person. The receiving unit 14 also alternately receives a radio wave for detecting a human body and data transmitted from the device, and controls the device in the house based on information on the operation of the human body. For example, in a room where no person 15 is present, the lighting 3 and the air conditioner 2 are turned off, and wasteful power can be saved. Further, in the case of the toilet 6, it is possible to turn on the power of the heating toilet seat function (not shown) and the deodorizing function (not shown) in the toilet seat 7 with the washing function at the same time when the person 15 enters the toilet 6. Energy saving can be realized. In addition, a crime prevention device 11 is provided on a wall portion near an entrance, either outdoors or indoors, and an internal sensor detects an intruder, which also has an excellent security function. In addition, AV equipment 4,
The electronic carpet 10 can also be controlled by the operation information of the human body. The control of the above-described devices is performed by the control box 1 transmitting radio waves carrying data information (not shown), receiving the data by each device, and further decoding the data, and the device itself performs the control. The data carries unique information such as an ID in order to prevent interference. Radio waves for human body detection and data for device control are alternately transmitted from the transmission unit 12 of the sensor 11 to communicate information on the state of human body operation and the device. The receiving unit 13 also alternately receives radio waves for human body detection and data transmitted from the device, and controls the device based on the state of operation of the human body.
