The present invention provides a home network system for controlling an electronic device by a sensor.

Hereinafter, a home network system will be described with reference to FIGS. 1 to 4. FIG.

FIG. 2 is a configuration diagram of a communication module coupled to the home appliance 21 of FIG. 1, 4 is a waveform diagram showing an output signal of the heart rate sensor 140 of Fig. 2. Fig.

The home network system 10 includes a home gateway system 40 and a plurality of electronic devices 21.

As shown in the figure, the home gateway system 40 is connected to an external communication network and is connected to a plurality of electronic devices 21 through an internal communication network.

The home gateway system 40 interfaces data communicated between an external communication network and a plurality of electronic apparatuses 21.

One or more electronic devices 21 may be included, and three electronic devices 21 are shown in this embodiment.

At this time, the electronic device 21 may be a portable terminal 30 connected to the home gateway system 40, for example, a notebook computer, a smart phone, or the like.

Each electronic device 21 is connected to the home gateway system 40 by a plurality of various types of networks.

At this time, various types of networks can transmit / receive data with different transmission bandwidths, and a wireless scheme such as Zigbee, Bluetooth, geo-wave, or Wi-Fi can be applied according to the coverage of the home gateway system 40.

The electronic device 21 typically has a network function such as an Internet refrigerator, a digital TV, a set-top box, and the like, which can be connected to an external communication network such as a high-speed communication network in the home as a variety of multimedia services, Various home appliances and the like can also be considered.

Also, the electronic device 21 includes at least one lighting device controlled by a dimming device or the like connected to the home gateway system 40.

In addition, the electronic device 21 includes at least one sensing module 22 disposed in the home. The configuration of the sensing module 22 will be described later.

The home gateway system 40 includes a wireless communication unit 41 and a server 42 as shown in FIG.

The wireless communication unit 41 transmits a turn-on signal to the electronic device 21 controlled by wireless communication in the home in at least one wireless communication system.

The server 42 is connected to the wireless communication unit 41 and the external communication network and stores a device activation signal of the electronic device 21 transmitted to the wireless communication unit 41, Store the turn-on signal.

The server 42 may further include a storage unit for storing the device activation signal and the turn-on signal.

The server 42 may be connected to the portable terminal 30 through a cloud network, which is an external network, to control the electronic devices 21 in the home.

The electronic device 21 includes at least one sensing module 22 disposed in the home, and the sensing module 22 has the same configuration as that of FIG.

2, the sensing module 22 includes an input unit 110, a radio processing unit 120, a controller 130, and a heart rate sensor 140 connected to the antenna 101. [

The antenna 101 transmits the device activation signal to the home gateway system 40 via the wireless network.

The input unit 110 amplifies and filters the signal from the radio processing unit 120, and transmits the signal to the antenna 101.

The radio processing unit 120 processes a device operation signal generated from the controller 130, and generates and outputs a radio signal corresponding to the frequency.

The control unit 130 obtains an output signal from the heart rate sensor 140 and reads the output signal to generate a device operation signal for turning on the home appliance 21. [

The heart rate sensor 140 is a sensor for sensing the heartbeat of a person who is separated from the sensor, and may be a potential difference sensor or an electric field sensor.

That is, according to the heartbeat of a human body, a small potential difference in free space or a change in an electric field is sensed by a capacitive coupling method to output a voltage.

As described above, in the case of the home network system 10 having the sensing module 22 including the non-contact heart rate sensor 140, the heart rate sensor 140 generates an output signal depending on the presence or absence of a person in the home, The electronic device 21 can be turned on and off.

Hereinafter, the operation of the home network system 10 of the present invention will be described with reference to FIG. 3 and FIG.

When operation begins, the heart rate sensor 140 senses the heartbeat of a person in a free space, in the home, in an embodiment, and generates an output signal therefor.

The controller 130 of the sensing module 22 obtains an output signal from the heartbeat sensor 140 at a predetermined period (S10) and reads the presence or absence of a person.

The output signal of the heart rate sensor 140 is shown in FIG.

That is, the voltage of the sense capacitor coupled by the change of the electric field on the free space varies with time, and the output voltage varies.

When a person is present and a potential difference of the free space is largely generated according to the heartbeat, the output voltage becomes larger than the threshold voltage Vth.

At this time, if an output signal having a value equal to or greater than the threshold voltage (Vth) is obtained, it is determined that there is a person (S30).

If it is determined that a person is present, the controller 130 determines whether the first reference time T1 has elapsed since the device operation signal was output (S40).

If the first reference time T1 has elapsed, the control unit 130 generates a device activation signal (S50).

The first reference time T1 may be longer than the period during which the controller 130 obtains the output signal.

The device activation signal is for turning on the electronic device 21 interlocked with the home network system 10, and the electronic device 21 may be an illumination device or an air conditioner, a TV, or the like.

When the device operation signal is generated, the control unit 130 turns on the wireless processing unit 120, processes the device operation signal into a wireless signal by the wireless processing unit 120, and transmits the wireless operation signal to the home gateway system 40 via the antenna 101. [ (S60).

The home gateway system 40 receives the device activation signal from the sensing module 22 through the wireless network and transmits a turn-on signal to the electronic device 21 through the wireless network at step S70.

At this time, both the operation signal of the device 42 received by the server 42 and the information of the turn-on signal of the output device are recorded (S80).

The electronic device 21 receiving the turn-on signal is turned on by the turn-on signal, and the electronic device 21 maintains the operation even if no other turn-on signal is obtained during the second reference time T2.

On the other hand, when the first reference time T1 has not elapsed in the sensing module 22, the device operation signal is not generated even if the output signal has a value larger than the threshold voltage Vth.

That is, power consumption due to the turn-on of the radio processing unit 120 can be reduced by maintaining the operation by the previous device operation signal during the first reference time T1.

The controller 130 of the sensing module 22 generates a device operation signal for an output signal greater than the threshold voltage Vth when the first reference time T1 elapses.

In the case of the home network system 10, the device activation signal may be transmitted to the dimming device or the switch device linked to the wireless network to control the electronic device 21 without being transmitted to the home gateway system 40 .

The dimming device or the switch device may be connected to the home gateway system 40 via a wired / wireless network to record the device activation signal and the turn-on signal.

In such a home network system 10, the sleep mode is set to control the sensing module and the electronic device, preferably the lighting device.

Hereinafter, a case where the sleep mode of the home network system 10 is set will be described with reference to FIG.

Referring to FIG. 5, the user can set the sleep mode in the home network system 10.

The sleep mode is defined as a mode for sensing the sleep state of the human body by sensing the heartbeat of the human body using the sensing module 22 and controlling the electronic device 21, preferably the lighting device accordingly.

When the sleep mode is applied to the home network system 10, the sleep mode is set in the sensing module 22 (S100).

When the sleep mode is set in the sensing module 22, the sensing module 22 senses the base heartbeat (S110).

The basal heart rhythm is the heart rhythm at the time of non-sleep of the human being present within the present sensing range.

Upon completion of the basal heartbeat sensing, the baseline heartbeat data is stored in a controller of the sensing module 22, and the baseline heartbeat is stored in the home gateway system.

The sensing module 22 defines the stored baseline heartbeat as a threshold value for determining the sleep / non-sleep state of the human body by setting the stored heartbeat rate as a non-sleeping heart rate at step S120.

Next, the sensing module 22 periodically senses the heartbeat of the human body as shown in FIG. 3 (S130).

The sensing method of the sensing module 22 is the same as that of Fig.

At this time, if the sleep mode is set, the threshold voltage of FIG. 3 becomes the threshold value of the base heartbeat, and it is determined whether the voltage value of the sensed heartbeat is different from the threshold voltage (S140).

If there is no difference from the threshold voltage or the difference is within the error range, the sensing module 22 determines that it is in a non-sleep state and generates a start signal for turning on the electronic device 21, preferably the lighting device ).

On the other hand, when the difference value exceeds the error range, it is determined that the apparatus is in a sleep state, and a device turn-off signal for turning off the lighting apparatus is transmitted (S160).

The device turn-on signal may be directly transmitted from the sensing module 22 to the lighting device according to the home network system 10, and the control information may be transmitted to the gateway system while directly controlling the lighting device, have.

On the other hand, as shown in FIG. 3, the device turn-off signal may be transmitted to the gateway system 40, and the gateway system 40 may transmit the turn-off signal to the lighting device.

In the case of the home network system 10 having the sensing module 22 including the heart rate sensor 140, the sleep mode can be set to control the lighting device according to whether the person is in the sleep state or not.

Hereinafter, another embodiment of the present invention will be described with reference to FIG.

6, the sensing module 22 includes an input unit 110, a radio processing unit 120, a controller 130, a heart rate sensor 140, and an auxiliary sensor 150 connected to the antenna 101 .

The antenna 101 transmits the device activation signal to the home gateway system 40 via the wireless network.

The wireless communication unit 430 processes the device operation signal generated from the controller 130, and generates and outputs a wireless signal corresponding to the frequency.

The control unit 130 obtains an output signal from the heart rate sensor 140 and reads the detection signal to generate a device operation signal for turning on the home appliance 21. [

The heart rate sensor 140 is a sensor for sensing the heartbeat of a person who is separated from the sensor, and may be a potential difference or an electric field sensor.

As described above, in the case of the home network system 10 having the sensing module 22 including the non-contact heart rate sensor 140, the heart rate sensor 140 generates an output signal depending on the presence or absence of a person in the home, The electronic device 21 can be turned on and off.

The auxiliary sensor 150 may be a temperature sensor.

The temperature sensor reads the temperature change of the room in real time and transmits it to the control unit 130.

The control unit 130 may generate an on-off signal of a device operation signal, that is, an illumination device, an air conditioner, a boiler, or the like, by combining the output signals of the heart rate sensor 140 and the temperature sensor.

When a temperature sensor is included, even if a person is present in the room, if the temperature satisfies the threshold value, the device operation signal for the temperature control device may not be generated.

Hereinafter, the sleep mode of the home network system including the sensing module of FIG. 6 will be described with reference to FIG.

Referring to FIG. 7, the user can set the sleep mode in the home network system 10.

The sleeping mode is defined as a mode for sensing whether the user is sleeping by sensing the heartbeat and the temperature change of the human body using the sensing module 22, and controlling the electronic device 21, preferably the lighting device accordingly.

When the sleep mode is applied to the home network system 10, a sleep mode is set in the sensing module 22 (S200).

When the sleep mode is set in the sensing module 22, the sensing module 22 senses the basal heart beat and the basal body temperature (S210).

The basal heart rhythm is the heart rhythm at the time of non-sleep of the human being present within the present sensing range.

The basal body temperature refers to the temperature at the time of non-sleeping of the human body present within the present sensing range.

Upon completion of the basal heartbeat and basal body temperature sensing, the baseline heartbeat and baseline body temperature data are stored in a controller of the sensing module 22, and the baseline heartbeat and baseline body temperature are stored in the home gateway system.

The sensing module 22 defines the baseline heartbeat and hypothermic temperature to be stored as the heart rate during non-sleeping and the body temperature during non-sleeping, respectively, as a threshold value for determining the sleep / non-sleep of the human body (S220).

Next, the sensing module 22 periodically senses the heartbeat of the human body as shown in FIG. 3 (S230).

The sensing method of the sensing module 22 is the same as that of Fig.

At this time, if the sleep mode is set, the threshold voltage of FIG. 3 becomes the threshold value of the base heartbeat, and it is determined whether the voltage value of the sensed heartbeat is different from the threshold voltage at step S240.

If the difference from the threshold voltage does not occur or is within an error range, the heartbeat sensing is periodically performed (S250) while keeping the electronic device 21, preferably the lighting device, turned on.

On the other hand, when the difference value exceeds the error range, the sensing module 22 senses the temperature (S260).

If the temperature does not differ from the threshold value or falls within an error range, the electronic device 21, preferably the lighting device, is kept turned on (S290).

On the other hand, if the temperature difference also exceeds the threshold value and the error range is exceeded, it is determined that the apparatus is in a sleep state and a device turn-off signal for turning off the lighting apparatus is sent (S295).

The device turn-on signal may be transmitted directly to the lighting device from the sensing module 22 according to the home network system 10, and control information may be transmitted to the gateway system 40 while directly controlling the lighting device Can be recorded.

On the other hand, as shown in FIG. 3, the device turn-off signal may be transmitted to the gateway system 40, and the gateway system 40 may transmit the turn-off signal to the lighting device.

Accurate data can be obtained by sensing the heartbeat sensor 140 and the temperature sensor through the secondary sensor, and it is possible to control the lighting device according to whether a person is in a sleep state or not by setting a sleep mode.

Referring to FIG. 8, the electronic device 21A includes the sensing module 22 of FIG. 2 and is shown as an example of a lighting device.

That is, when the electronic device 21A is an illuminating device, a home network system 40 and a wireless communication module for performing transmission and reception through a wireless network are required.

The electronic device 21A of FIG. 6 includes the sensing module 22 as a wireless communication module.

When the sensing module 22 is attached to the electronic device 21A, the control unit 130 of the sensing module 22 receives an output signal from the heartbeat sensor 140 and the auxiliary sensor 150, And processes it in the radio processing unit 120 and outputs it.

At this time, when the home gateway system 40 generates and outputs a turn-on signal based on the device operation signal, the sensing module 22 receives the turn-on signal and transmits a turn-on signal to the control unit of the connected electronic device 21.

Therefore, the electronic device 21 can receive the control signal using the wireless processing unit 120 of the sensing module 22 without a separate wireless communication module, thereby reducing the cost.
