가로등 시스템Street light system

본 발명은 가로등 시스템에 관한 것으로, 특히 LED를 사용함으로써 소모 전력을 감소시키고 인터넷 단말기 및 액세스 포인트를 이용하여 야외에서도 VoIP 통신이 가능한 가로등 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a street lamp system, and more particularly, to a street lamp system that reduces power consumption by using LEDs and enables VoIP communication outdoors using an Internet terminal and an access point.

최근에는, 인터넷을 이용한 인터넷 전화기의 사용이 증가하고 있다. 인터넷 전화기는 VoIP (Voice over Internet Protocol)을 이용한다. VoIP는 음성 데이터를 인터넷 프로토콜 데이터 패킷으로 변환하여 전송함으로써 음성 통화를 가능하게 한다. 인터넷 전화기는 다른 인터넷 전화기와의 통화뿐만 아니라, 전통적인 일반 전화기, 이동 전화기와의 통화가 가능하다. 인터넷 전화기는 확장성도 뛰어나며 기존 전화에 비하여 요금도 훨씬 저렴하다는 장점이 있어 널리 사용된다.In recent years, the use of the Internet telephone using the Internet is increasing. Internet phones use Voice over Internet Protocol (VoIP). VoIP enables voice calls by converting and transmitting voice data into Internet Protocol data packets. Internet telephones can talk with other conventional telephones, as well as with traditional telephones and mobile phones. Internet phones are widely used because they offer excellent scalability and far lower costs than traditional phones.

그러나, 인터넷 전화는 인터넷 접속이 가능한 지역에서만 사용이 가능하다. 인터넷 전화는 액세스 포인트(Access Point)를 통해 통신이 가능하므로, 액세스 포인트가 설치된 가정이나 사무실에서만 전화 통화가 가능하다. 따라서, 액세스 포인트가 설치되지 않은 야외에서는 인터넷 전화기의 사용이 불가능하다는 문제점이 있다.However, Internet telephony can only be used in areas with Internet access. Internet telephony can communicate through an access point, so telephone calls can only be made in a home or office with an access point. Therefore, there is a problem that it is impossible to use the Internet telephone in the outdoor where the access point is not installed.

상술한 문제점을 해결하기 위하여, 본 발명은 특히 LED를 사용함으로써 소모 전력을 감소시키고 인터넷 단말기 및 액세스 포인트를 이용하여 야외에서도 VoIP 통신이 가능한 가로등 시스템을 제공하는 것을 그 목적으로 한다.In order to solve the above problems, an object of the present invention is to provide a street light system that can reduce the power consumption by using LED in particular, and VoIP communication is possible even outdoors using the Internet terminal and access point.

도 2는 본 발명에 따른 가로등 시스템의 각 가로등의 구성을 도시한 블록도.Figure 2 is a block diagram showing the configuration of each street lamp of the street lamp system according to the present invention.

이하에서는, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 1은 본 발명에 따른 가로등 시스템을 도시한 개략도이다.1 is a schematic diagram illustrating a street lamp system according to the present invention.

도 1을 참조하면, 본 발명에 따른 가로등 시스템은 도로에 설치되어 인터넷 단말기(200)와 통신하는 복수개의 가로등(20a, 20b, 20c, 20d)을 포함한다. 복수개의 가로등(20a, 20b, 20c, 20d)을 포함하며, 각 가로등은 약 5 내지 15m의 간격으로 배치될 수 있다.Referring to FIG. 1, a streetlight system according to the present invention includes a plurality of streetlights 20a, 20b, 20c, and 20d installed on a road and communicating with an internet terminal 200. It includes a plurality of street lights (20a, 20b, 20c, 20d), each street light may be arranged at intervals of about 5 to 15m.

도 2는 본 발명에 따른 가로등 시스템의 각 가로등의 구성을 도시한 블록도이다.Figure 2 is a block diagram showing the configuration of each street light of the street lamp system according to the present invention.

도 2를 참조하면, 본 발명에 따른 각 가로등은 제어부(100), 액세스 포인트(110), 광원 구동부(120) 및 광원(130)를 포함한다. 본 발명에 따른 각 가로등은 조도 센서부(140)를 더 포함할 수 있다.2, each street light according to the present invention includes a controller 100, an access point 110, a light source driver 120, and a light source 130. Each street lamp according to the present invention may further include an illumination sensor unit 140.

제어부(100)는 본 발명에 따른 가로등 시스템에 대한 전반적인 제어를 수행한다.The controller 100 performs overall control of the street lamp system according to the present invention.

구체적으로는, 제어부(100)는 인터넷 단말기(200)와 무선 통신을 수행하기 위하여 액세스 포인트(110)를 제어한다. 또한, 인터넷 단말기(200)와 액세스 포인트(110) 간에 무선 통신이 수행되면 광원 구동부(120)를 제어하여 광원(130)의 밝기를 조절한다.Specifically, the controller 100 controls the access point 110 to perform wireless communication with the Internet terminal 200. In addition, when wireless communication is performed between the Internet terminal 200 and the access point 110, the brightness of the light source 130 is adjusted by controlling the light source driver 120.

광원(130)은 하나 이상의 LED(Light Emitting Diode)를 포함한다. 상기 LED는 백색 LED인 것이 바람직하다. LED는 기존의 할로겐 램프에 비하여 전력 소모량이 현저히 적고, 유지 및 보수를 거의 필요로 하지 않는다. 따라서, 관리 비용을 최소화할 수 있다는 장점이 있다.The light source 130 includes one or more light emitting diodes (LEDs). It is preferable that the LED is a white LED. LEDs consume significantly less power than conventional halogen lamps and require little maintenance and repair. Therefore, there is an advantage that the management cost can be minimized.

광원 구동부(120)는 상기 복수개의 LED로 구성되는 광원(130)을 구동한다. 광원 구동부(120)는 제어부(100)의 제어에 따라 광원(130)을 ON/OFF하거나 밝기를 조절하는 기능을 한다. 예를 들어, 가로등 주변의 인터넷 단말기(200)가 액세스 포인트(110)를 통하여 인터넷으로의 접속을 시도하면, 제어부(100)는 광원 구동부(120)를 제어하여 광원(130)을 턴-온한다.The light source driver 120 drives the light source 130 including the plurality of LEDs. The light source driver 120 functions to turn on / off the light source 130 or adjust the brightness under the control of the controller 100. For example, when the Internet terminal 200 around the street lamp attempts to access the Internet through the access point 110, the controller 100 controls the light source driver 120 to turn on the light source 130. .

액세스 포인트(110)는 인터넷 단말기(200)와 무선 통신을 수행하며, 인터넷에 접속된다.The access point 110 performs wireless communication with the internet terminal 200 and is connected to the internet.

인터넷 단말기(200)는 Spype 등 VoIP 통신이 가능한 인터넷 전화인 것이 바람직하다. 또한 노트북 PC, UMPC 등 음성 통신이 가능한 하드웨어가 장착된 인터넷이 가능한 휴대용 PC일 수도 있다.The internet terminal 200 is preferably an internet phone capable of VoIP communication such as Spype. In addition, it may be a portable PC capable of internet with hardware capable of voice communication, such as a notebook PC or UMPC.

조도 센서부(140)는 주변 환경의 조도를 감지하고 감지된 조도를 전기적인 신호로 변환하여 제어부(100)에 전송한다. 제어부(100)는 조도 센서부(140)가 전송한 조도에 따라 광원 구동부(120)를 제어하여 광원(130)의 밝기를 조절한다. 예를 들어, 초저녁에는 광원(130)의 밝기를 상대적으로 어둡게 하고, 늦은 밤에는 광원(130)의 밝기를 상대적으로 밝게 할 수 있다.The illuminance sensor unit 140 detects the illuminance of the surrounding environment, converts the detected illuminance into an electrical signal, and transmits it to the control unit 100. The controller 100 controls the light source driver 120 according to the illuminance transmitted by the illuminance sensor unit 140 to adjust the brightness of the light source 130. For example, the brightness of the light source 130 may be relatively dark in the early evening, and the brightness of the light source 130 may be relatively bright in the late night.
