Hereinafter, with reference to the accompanying drawings will be described in detail for the practice of the present invention.

1 shows a configuration of an LED lighting system based home care network system according to the present invention.

Referring to FIG. 1, the LED lighting system-based home care network system includes a control device 100, an LED lighting system 200, a smart device 300, and a smart device 300 corresponding to a smart gateway (G / W). It includes a sensor 400 connectable through. In addition, the home care network system may be connected to a system such as an external institution that provides smart life care through an external server 500.

2 shows a detailed configuration of a control device and a smart device according to the present invention. First, the control device 100 includes a configured VLC system defining unit 110, a data collecting unit 120, a communication unit 130, and a control unit 140.

The VLC system definition unit 110 is configured to transmit and receive a signal through one or more smart devices 300 through visible light communication (VLC) through indoor LED lights. Here, the VLC system definition unit 110 receives capability information capable of performing VLC communication from one or more smart devices 300, and VLC communication with one or more smart devices 300 based on the capability information. Do this. Accordingly, the VLC system defining unit 110 may be referred to as a VLC communication setting unit 110.

Meanwhile, the data collector 120 is configured to collect user healthcare information collected by the at least one smart device 300 from the sensor 400 connected through the air interface through the VLC. Here, the sensor 400 is a biosensor and is configured to collect health care information (ie, biometric information) of the user.

The sensor 400 may measure a user's heart rate, body temperature, blood pressure, etc. in real time and transmit such sensing information (ie, biometric information) to one or more smart devices 300. In this case, the sensor 400 may not be directly connected to the control device 100, the LED lighting system 200, or an external server 500, and may be connected only to one or more smart devices 300 through a specific air interface.

In this case, the smart device 300 operates in a proxy mode for the sensor 400, and the specific wireless interface may be a short range communication interface such as Bluetooth or Zigbee. Alternatively, although the sensor 400 is not interfaced with the VLC, the sensor 400 may support a transparent mode that is directly interfaced with the control device 100 through another wireless interface. Here, the other wireless interface may be WiFi, UWB, or the like, which may be directly interfaced with the control device 100. However, what is limited to this interface can be freely changed depending on the application.
