IoT-based smart lighting control device and its method {APPARATUS FOR IoT BASED SMART LIGHTING CONTROL AND THE CONTROL METHOD THEREOF}

The present invention relates to an IoT-based smart lighting control device and method thereof, and more particularly, to a smart phone for lighting control in a network environment using a gateway and an external server directly requesting a session to each lighting device provided in the premises. It is possible to reduce the power consumption of each lighting device and the occurrence of traffic due to transmission of a session request by collectively transmitting it to the gateway without transmitting. Also, the lighting status of each lighting device under session management through the gateway can be reduced. IoT that allows the verified user to remotely control the operation of the lighting device through TCP/IP communication using a smartphone or an external server, and then run the lighting device through short-range wireless communication in accordance with the user's remote control at the gateway. It relates to a smart lighting control device based and a method thereof.

In general, a fluorescent lamp or an incandescent lamp has been mainly used as a lighting device, and in recent years, it is gradually changing to a light emitting diode (LED) that is eco-friendly, consumes little power, and has high light efficiency.

The lighting device may be individually connected to a switching device and controlled on/off, or a plurality of lighting devices may be connected to a switching device through a single wire to be controlled on/off at the same time. In this case, the control of the lighting device includes, in addition to basic on/off control, dimming control that changes the illuminance or intensity of the light source, the illuminance of the light source according to the user's emotion, color temperature, and emotional lighting control including a combination thereof. I can.

In addition, in addition to controlling the lighting device on/off by wire as described above, it can be controlled on/off by short-range wireless communication methods such as infrared, Bluetooth, and beacons through a remote controller, and externally in an environment using a gateway. A located user can control on/off the lighting device connected to the gateway through a smartphone or an external server.

At this time, when the user wants to control the operation of the lighting device in the premises through the gateway from the outside, the communication connection or operation status of the lighting device must be checked. To this end, it is necessary to always maintain a session between the smartphone and the external server and each lighting device in the premises connected to the gateway.

This procedure is called keep-alive, and the general keep-alive procedure is to periodically send packets without payload in order to always maintain a session between end devices (i.e., smartphones and external servers and each lighting device in the premises). If there is no packet exchange with each other for the specified time or if there is no response to the keep-alive packet, the connection is disconnected.

The main reason for using Keep Alive is to detect whether one of the end devices is in a state where communication is not possible, and arrange the connection state that is open only to one side, thereby preventing unnecessary operation and always receiving event packets from the other party. This is to keep the session going.

However, the method of implementing the keep-alive operation as described above is not only a network environment using a public IP, but also a smart phone or external servers in a network environment using a network address translation (NAT) device that shares IP. Since each lighting device in the department and the premises must always maintain a one-to-one session, each lighting device in the premises must be in a standby state at all times, so power consumption increases and power management cannot be easily performed. There is a problem that traffic increases due to direct transmission of keep-alive requests to the lighting device periodically.

Also, in the case of lighting devices controlled through short-range wireless communication such as Bluetooth, even if a remote control system is implemented based on the gateway environment, the lighting control signal transmitted through TCP/IP communication (wired and wireless Internet) from the outside and the communication method are different. The operation of the lighting device could not be controlled based on an external lighting control signal, and there was a problem in that the driving method of the lighting device had to be changed for remote control.

Therefore, in the present invention, in a network environment using a gateway, a smartphone for lighting control and an external server do not directly transmit a session request to each lighting device provided in the premises, but collectively transmit a session request to the gateway, so that each lighting device The purpose of this study is to propose a method to reduce the power consumption and traffic generation due to transmission of session requests.

In addition, in the present invention, when the user remotely controls the operation of the lighting device through TCP/IP communication (wired/wireless Internet), the gateway drives the lighting device through short-range wireless communication such as Bluetooth according to the user's remote control. The purpose of this study is to propose a method to easily control the lighting equipment in the premises through data conversion of TCP/IP communication or short-range wireless communication.
