Description

Detailed Description of the Invention

[0001]

[Industrial field of use] The present invention relates to a system device in which a home electric appliance and an information device are combined in the HA (home automation) field.

[0002]

2. Description of the Related Art Conventionally, home electric appliances have been designed to be used alone and can be used in combination with other equipment to provide convenient functions.
It is not designed to have more advanced functions in combination. For example, it is a product that is used alone without being used in combination with other products or devices other than a combination with a remote control device such as a television, a refrigerator, a room air conditioner, a heating appliance, a washing machine, a microwave oven, and a lighting fixture. As an example, in an electronically controlled carpet of a heating appliance, a control unit is provided at a corner of the carpet, and is provided with convenient functions such as temperature adjustment, heating area switching, rapid heating, and off timer. However, when the room temperature is extremely low in the single product form, for example, high temperature setting is used to perform rapid heating with a wide heating area, and as the room temperature rises, the heating set temperature and heating area are adjusted appropriately. , Return to normal heating, etc.,
It was not possible to perform detailed control such as automatic operation of heating power on / off and reduction of electricity charges according to conditions such as driving, people being present, and people not being present. Also, as another example, even in the case of a lighting fixture, in order to avoid the trouble of forgetting to turn it off and turning on and off as necessary, it is unavoidable that it is left unsuited. There is a tendency to get rid of. Both examples show the limits of individual products.

SUMMARY OF THE INVENTION According to the present invention, the presence or absence of a person in a room is judged based on the output of a pressure sensor incorporated in an electronically controlled carpet, and the carpet heating is appropriately adjusted by itself. Providing a carpet and providing a wireless device on the carpet, wirelessly transmitting information such as whether or not a person is present in the room to a wireless controller. For example, the wireless controller determines whether the person is present. The purpose is to provide a carpet system that controls electronically controlled carpets wirelessly by taking into account information such as whether or not there is room temperature and the room temperature, and also operates room air conditioners, etc., and controls electric locks. And

[0004]

To achieve the above object, a heating setting section, a sensor section, a control section, an AC power supply section, a DC power supply section, a heater section, and a clock section are provided in an electronically controlled carpet.

Further, a carpet system is constituted by a carpet provided with a wireless unit on the electronically controlled carpet, a wireless controller, a tele controller, a room air conditioner, a lighting fixture, a ventilation fan, an electric lock, and a room temperature sensor.

[0005]

Since the present invention is configured as described above, for example, when a person steps on the carpet, the pressure sensor of the sensor section senses the pressure and outputs a pressure sensing signal. The control unit determines whether there is a person or not based on the signal from the pressure sensor and the information of the time counting unit. Further, the pressure detection signals of the plurality of pressure sensors are logically operated by the sensor unit and output as pressure information to the control unit. The control unit determines the presence of a plurality of persons from the pressure information. Based on that judgment,
Carpet heating is turned on or off partially or entirely, and automatic operation such as temperature adjustment is performed.

Next, the operation of the carpet system will be described. The wireless unit provided on the carpet transmits a wireless signal including information about whether or not a person is present to the wireless controller. The wireless controller instructs the telecontroller based on the information of the presence / absence of a person who demodulates and demodulates the signal and the information of the room temperature sensor, and controls, for example, the room air conditioner. In addition, the wireless controller performs simultaneous wireless communication with a plurality of ID (identification) numbers by an MCA (multi-channel access) method that automatically selects an empty channel, and based on information from a plurality of carpets, Judge whether there are people in the house or not.

When it is determined that there is no person, the timer unit 8 measures, for example, the time during which the information from the sensor unit is interrupted, and the signal output from the pressure sensor is output even after the set time of 3 minutes elapses. Since there is no such person, it can be judged that no one is present. In this case, turn off the heater.

The operation will be described based on an embodiment of a carpet provided with a wireless device according to the present invention. Control unit 4
Determines whether there is a person, a plurality of persons, or no person based on the information from the sensor unit, adds an ID (identification) number, and creates a signal including the determination. , To the wireless unit 10, and wirelessly transmitted from the wireless unit. In addition, the control unit demodulates the wireless signal with the ID (identification) number received by the wireless unit at any time, and controls each unit of the carpet for the heating operation.

Specifically, the carpet 10 transmits a radio signal, and the radio controller 30 receives the radio signal. For example,
When there is no person, the wireless controller via the tele-controller 20, the room air conditioner 21 and the lighting fixture 22.
Power off. It also controls the electric lock 25 provided at the entrance. When a person is present, the wireless controller starts the operation of the room air conditioner via the tele controller. In addition, in the information of the temperature sensor 40, for example,
If the room temperature is low, the carpet is wirelessly instructed to perform an area heating operation. When the room temperature is high, the carpet is wirelessly instructed to slightly lower the heating set temperature and heat the carpet. Furthermore, heating is stopped. Also, when there are a plurality of people, the carpet is wirelessly instructed to lower the heating set temperature slightly and heat the carpet. Similarly, sensor signals from the carpet can be used to control ventilation, lighting, and electric locks at the entrance.

In the single use, by laying the carpet in the room, the presence / absence of the resident can be surely determined, and accordingly, the heating control of the carpet itself can be automatically and appropriately performed. Next, in the usage incorporated in the system, in the HA (home automation) field, for example, in the information management system of a condominium or a dormitory, it is possible to confirm the presence / absence of the presence / absence of a resident.
It is considered important in safety management for disaster prevention and crime prevention. 2. Description of the Related Art Conventionally, a presence / absence management system is known, which uses a name tag to manually display / confirm presence / absence, or to read an ID (identification card) on a terminal device when a resident goes out. ing. However, if you inadvertently forget to operate the name tag or if you have an ID card,
Although there are problems such as frequent malfunctions and low reliability depending on the terminal device, the carpet of the present invention can detect the presence / absence of a resident reliably, and is therefore suitable for application in this field. Furthermore, since the carpet system of the present invention wirelessly transmits and receives information, it is not necessary to wire a new electric wire or the like in the home. According to the above description, in the carpet system to which the carpet of the present invention is applied, the room air conditioner, the lighting fixture, the ventilation fan, the electric lock, the carpet, etc. are controlled after grasping the presence / absence of a resident, and therefore it is comfortable. Therefore, it is possible to realize an economical and safe environment for disaster prevention and crime prevention. Therefore, the use of the HA system can be expanded.
