Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

도 1은 본 발명의 일 실시예에 따른 RFID를 이용한 위치 추적 시스템을 도시한 개념도이다.1 is a conceptual diagram illustrating a location tracking system using RFID according to an embodiment of the present invention.

본 발명은 RFID 기술을 이용하여 위치를 추적하는 시스템에 관한 것으로서, RFID(Radio Frequency IDentification) 기술이란 사물에 전자태그를 부착하고, 각 전자태그의 고유 아이디를 무선으로 인식하여, 해당 정보를 수집, 저장, 가공, 추적함으로써 사물에 대한 측위, 원격처리, 관리, 및 사물 간 정보교환 등의 서비스를 제공하는 기술로서 환경 감시, 군수, 의료 등 다양한 분야에서 활용되고 있다.The present invention relates to a system for tracking a location using an RFID technology. An RFID (Radio Frequency IDentification) technology attaches an electronic tag to an object, wirelessly recognizes a unique ID of each electronic tag, and collects corresponding information. It is a technology that provides services such as positioning, remote processing, management, and information exchange between objects by storing, processing, and tracking them, and is being used in various fields such as environmental monitoring, logistics, and medical care.

도 1에 도시된 바와 같이 본 발명의 일 실시예에 따른 RFID를 이용한 위치 추적 시스템은 크게 위치 추적 대상에 부착되는 RFID 태그(100)와 상기 RFID 태그(100)와 무선 통신을 수행하는 다수의 RFID 리더(200)와 상기 RFID 리더(200)와 유선 또는 무선 통신을 수행하며, 상기 태그(100)와 상기 리더(200)의 정보를 저장 및 분석하여 상기 태그(100)의 위치를 계산하는 서버(300) 및 상기 서버(300)로부터 위치 추적 정보를 수신하는 휴대용 단말기(400)로 구성될 수 있다.As shown in FIG. 1, a location tracking system using RFID according to an exemplary embodiment of the present invention has a large number of RFID tags 100 attached to a location tracking object and a plurality of RFIDs performing wireless communication with the RFID tag 100. The server 200 performs wired or wireless communication with the reader 200 and the RFID reader 200, and stores and analyzes information of the tag 100 and the reader 200 to calculate a location of the tag 100. 300 and a portable terminal 400 for receiving location tracking information from the server 300.

상기 RFID 태그(100)는 고유한 식별정보를 저장하고 하는 RFID 칩과, 작동에 필요한 전원을 공급하는 배터리와 안테나를 포함하여 구성된다. 바람직하게는 자체적으로 RF신호를 송신하고, 자체의 전원부로부터 모든 작동에 필요한 전원을 공급받고 데이터 전송이 가능한 능동형 태그(100)를 사용하는 것이 바람직하며, 상기와 같은 태그(100)는 위치 추적의 대상이 되는 사람 등에게 다양한 형태로 소지하게 할 수 있다.The RFID tag 100 includes an RFID chip for storing unique identification information, a battery for supplying power for operation, and an antenna. Preferably, it is preferable to use an active tag 100 which transmits RF signals by itself, receives power for all operations from its power supply unit, and can transmit data. You can have them in various forms.

다만, 위치 추적의 주대상이 어린아이나 노인 등인 경우를 고려하면, 들고 다닐 수 있는 카드나 지갑에 RFID 태그(100)를 장착하는 것은 분실의 위험이 있으므로 목걸이 또는 손목이나 발목에 착용할 수 있는 밴드에 장착하는 것이 바람직하다.However, considering the case where the main target of location tracking is a child or an elderly person, the RFID tag 100 is mounted on a portable card or a wallet, which can be worn on a necklace or a wrist or ankle because there is a risk of loss. It is preferable to mount on.

상기 RFID 리더(200)는 RFID 태그(100) 및 서버(300)와 유무선 통신을 할 수 있는 통신 모듈(미도시)을 구비하여 상기 구성요소들 사이의 통신을 중계하고, 자신의 식별 정보나 위치 정보 등을 서버(300)에 전송한다.The RFID reader 200 is provided with a communication module (not shown) capable of wired and wireless communication with the RFID tag 100 and the server 300 to relay communication between the components, and their identification information or location. Information and the like are transmitted to the server 300.

특히, 본 발명의 경우에는 도 2에 도시된 바와 같이 다수의 RFID 리더(200)가 위치 추적 구역(해변)에 소정 간격으로 다수 배치되도록 한다. 위치 추적 대상이 되는 치매노인이나 어린아이는 RFID 태그(100)가 포함된 손목밴드나 목걸이를 착용함으로써 상기 다수의 RFID 리더(200)와 정보를 송수신하게 된다.In particular, in the case of the present invention, as shown in FIG. 2, a plurality of RFID readers 200 are arranged at a predetermined interval in a location tracking area (beach). Dementia elderly people or young children to be tracked by location is to send and receive information with the plurality of RFID reader 200 by wearing a wristband or necklace containing the RFID tag (100).

RFID 태그(100)의 위치를 정확하게 파악하기 위해서는, 리더(200)와 태그(100) 사이의 거리정보가 3개 이상 필요하다. 이를 위해 위치 추적 시스템의 리더(200)와 태그(100)가 무선신호의 전파 전달 속도를 이용하여 거리를 측정하게 되고 위치를 구하고자 하는 태그(100)는 3개 이상의 리더(200)와 무선통신이 가능하여야 한다.In order to accurately determine the position of the RFID tag 100, three or more pieces of distance information between the reader 200 and the tag 100 are required. To this end, the reader 200 and the tag 100 of the location tracking system measure the distance by using the radio wave propagation speed of the radio signal, and the tag 100 to obtain the location is wirelessly communicated with three or more readers 200. This should be possible.

그리고, 보다 정확하게 태그(100)의 위치를 파악하기 위해서는 태그(100) 주변으로 리더(200)를 많이 설치하는 것이 바람직하다.In addition, in order to more accurately grasp the position of the tag 100, it is preferable to install the reader 200 around the tag 100.

하지만 도 2에 도시된 바와 같이 해변가는 그 특성상 태그(100) 주변으로 3개 이상의 리더(200)를 설치하기 위해서는 백사장 내부에 리더(200)를 설치해야 하므로 현실적으로 구현하기 어려운 문제가 있었고 따라서 해변가에서 미아가 발생하거나 바닷물에 빠진 경우에 그 위치를 추적하기 어려운 문제가 있었다.However, as shown in FIG. 2, since the beach has to have a reader 200 installed inside the sandy beach in order to install three or more readers 200 around the tag 100, there is a problem that is difficult to realize in reality. In the event of a lost child or drowning in the sea, there was a problem that the location was difficult to track.

본 발명은 이러한 문제점을 해결하기 위한 것으로서, 소정의 구조물(500)을 설치하고 그 내부 또는 외부에 RFID 리더(200)를 설치한다. 도 3에서는 이러한 실시예로서 RFID 리더(200)가 구조물(500) 상부에 위치한 디스플레이(600)의 외측면에 설치된 것을 도시하고 있으나, 이에 한정되는 것은 아니고 상기 RFID 리더(200)를 디스플레이(600) 내부에 설치하거나 구조물(500) 내부에 설치할 수도 있다.The present invention is to solve this problem, install a predetermined structure 500 and install the RFID reader 200 inside or outside thereof. In FIG. 3, the RFID reader 200 is installed on the outer surface of the display 600 positioned above the structure 500, but the present invention is not limited thereto, and the RFID reader 200 is displayed on the display 600. It may be installed inside or installed inside the structure 500.

또한, 상기 구조물(500)은 다양한 형태로 제작될 수 있으나 해변에서의 안전을 고려하여 모서리가 없는 원기둥형으로 제작하는 것이 바람직하고, 보다 바람직하게는 파도에도 잘 쓰러지지 않도록 도 3에 도시된 바와 같이 하부로 갈수록 반경이 커지도록 제작할 필요가 있다.In addition, the structure 500 may be manufactured in various forms, but in consideration of safety on the beach, it is preferable to manufacture the cylinder without corners, and more preferably, as shown in FIG. It needs to be manufactured so that the radius becomes larger toward the bottom.

상기 구조물(500)의 재질은 시멘트와 혼화재와 섬유보강재와 물을 적정한 비율로 혼합한 고강도 콘크리트를 사용하는 것이 바람직하다. 다만 이러한 재질에 한정되는 것은 아니며, 상황에 따라 다양한 재질을 사용할 수 있다.As the material of the structure 500, it is preferable to use high-strength concrete mixed with cement, admixture, fiber reinforcement, and water at an appropriate ratio. However, the material is not limited thereto, and various materials may be used according to circumstances.

상기 구조물(500)의 높이는 3~3.5m 정도인 것이 바람직하나 이에 한정되는 것은 아니다. 구조물(500)의 높이가 너무 낮은 경우에는 사람의 손에 닿아 구조물(500) 상부에 설치된 장치들이 파손될 염려가 있고 바닷물에 잠길 염려가 있으며, 반대로 구조물(500)의 높이가 지나치게 높게 형성되면 구조물(500) 상부에 설치되는 디스플레이(600) 등을 육안으로 확인하기 어려운 문제가 있기 때문이다. The height of the structure 500 is preferably about 3 ~ 3.5m, but is not limited thereto. If the height of the structure 500 is too low, there is a risk that devices installed on the structure 500 may be damaged by being touched by human hands, and may be submerged in seawater. This is because it is difficult to visually check the display 600 installed on the upper part.

각각의 구조물(500)에는 상기 서버(300)와 유무선으로 통신하기 위한 통신모듈(미도시)이 설치될 수 있다. 통신모듈은 RFID 리더(200)에 포함될 수도 있지만 RFID 리더(200)와는 별도로 상기 서버(300)와 유무선으로 통신하기 위하여 구조물(500) 내부 또는 외부에 설치될 수 있다. 통신모듈은 서버(300)로부터 전송되는 정보를 수신하여 RFID 리더(200) 또는 디스플레이(600)에 제공하고, 반대로 RFID 태그(100) 및 RFID 리더(200)의 식별 정보, 위치 정보 등을 실시간으로 상기 서버(300)로 전송하게 된다.Each structure 500 may be provided with a communication module (not shown) for communicating with the server 300 by wire or wireless. The communication module may be included in the RFID reader 200 but may be installed inside or outside the structure 500 to communicate with the server 300 in a wired or wireless manner separately from the RFID reader 200. The communication module receives the information transmitted from the server 300 and provides the information to the RFID reader 200 or the display 600, and, conversely, identification information and location information of the RFID tag 100 and the RFID reader 200 are provided in real time. The server 300 transmits.

상기 디스플레이(600)는 도 3에 일 실시예로 도시된 바와 같이 구조물(500)의 상부에 설치될 수 있으며, 위치 추적 대상의 정보를 LCD, PDP, LED 등을 이용하여 시각적으로 제공한다. 다만 이러한 구조는 일 실시예이고 구조물의 외주면에 디스플레이를 매설하거나 구조물을 투명하게 형성하고 그 내부에 디스플레이를 설치하는 것도 가능하다.The display 600 may be installed on the upper portion of the structure 500, as shown in an embodiment of Figure 3, and provides a visual information of the location tracking target using the LCD, PDP, LED, and the like. However, such a structure is an embodiment and it is also possible to embed a display on the outer circumferential surface of the structure or to form the structure transparently and install the display therein.

또한, 상기 디스플레이(600) 외부 또는 내부에는 상기 RFID 리더(200)가 설치될 수도 있으며, 상기 RFID 리더(200)와 상기 디스플레이(600)는 유무선으로 연결됨으로써 상호간에 정보를 교환할 수 있다.In addition, the RFID reader 200 may be installed outside or inside the display 600, and the RFID reader 200 and the display 600 may be connected by wire or wireless to exchange information with each other.

예를 들어, 바닷가에서 RFID 태그(100)가 설치된 목걸이를 착용한 치매노인이나 어린아이가 실종된 경우 보호자가 신고하게 되면, 서버(300)에서 그 실종된 사람의 사진이나 나이, 보호자 연락처 등의 정보를 유무선 통신을 통해 다수의 구조물(500)에 설치된 디스플레이(600)를 통해 사람들에게 제공함으로써 신속하게 위치를 파악할 수 있도록 한다. 따라서 다수의 사람들이 실종된 사람의 얼굴을 확인할 수 있는 높이에 디스플레이(600)가 설치되어야 하기 때문에 상술한 바와 같이 구조물(500)의 높이는 3~3.5m 정도로 설치되는 것이 바람직하다.For example, when a dementia elderly person or a child wearing a necklace with RFID tag 100 installed on the beach is missing, the guardian reports, such as a picture or age of the missing person on the server 300, a guardian's contact number, etc. Information is provided to people through the display 600 installed in the plurality of structures 500 through wired or wireless communication so that the location can be quickly determined. Therefore, since the display 600 should be installed at a height where a large number of people can see the missing person's face, it is preferable that the height of the structure 500 is set to about 3 to 3.5 m as described above.

또한, 상기 디스플레이(600)와 상기 RFID 리더(200)는 해안가에 설치되는 경우 방수처리가 되어 있어야 하며, 강화 유리나 강화 플라스틱 등을 채용하여 물리적 화학적이 충격을 견딜 수 있도록 제작되어야 한다.In addition, the display 600 and the RFID reader 200 should be waterproof when installed on the shore, and should be manufactured to withstand the impact of physical and chemical chemicals by using tempered glass or reinforced plastic.

또한, 상기 디스플레이(600)를 이용하여 해변의 날씨나 파도 높이, 쓰나미 경보 등의 정보를 해변가의 사람들에게 보여 줄 수 있기 때문에 신속한 대응이 가능하게 되어 해변의 안전이 향상되며, 야간에는 상기 디스플레이(600)가 조명 역할을 함으로써 야간에 미아를 찾는 것을 용이하게 한다.In addition, since the display 600 can show information such as weather, wave height, tsunami warning, etc. of the beach to the people of the beach, it is possible to respond quickly to improve the safety of the beach, and the display at night ( The 600 acts as a light to facilitate finding a lost child at night.

상기 서버(300)는 3개 이상의 RFID 리더(200)로부터 상기 태그(100)와의 거리 정보를 수신하고 계산하여 상기 태그(100)의 위치를 파악한다.The server 300 receives the location information of the tag 100 from three or more RFID readers 200 and calculates the location information of the tag 100.

그리고 상술한 바와 같이 위치 추적 정보, RFID 태그(100)와 RFID 리더(200)의 식별정보, 보호자 정보 및 각종 날씨 상황이나 쓰나미 정보 등을 소정의 통신모듈을 구비하여 RFID 리더(200)나 디스플레이(600)로 제공하는 역할을 한다.Then, as described above, the RFID reader 200 or the display device having a predetermined communication module includes location tracking information, identification information of the RFID tag 100 and the RFID reader 200, guardian information, and various weather conditions or tsunami information. 600) serves to provide.

또한, 상기 서버(300)는 위치 추적 대상이 위치 추적 구역 외부로 이탈한 경우 이를 보호자에게 알리기 위한 메시지와 마지막 이탈 위치를 보호자 또는 관리인이 소지하는 휴대용 단말기(400)로 전송하는 기능을 구비할 수 있다. 따라서, 보호자나 관리인은 상기 서버(300)로부터 위치 추적 대상인 아이가 이탈하였다는 정보를 받게 되면, 마지막 이탈 위치를 서버(300)로부터 전송받음으로써 그 주위를 탐색하여 신속하게 위치를 파악할 수 있게 된다.In addition, the server 300 may have a function for transmitting a message for notifying the guardian and the last departure location to the portable terminal 400 possessed by the guardian or the manager when the location tracking object has moved out of the location tracking area. have. Therefore, when the guardian or the manager receives the information indicating that the child, which is the location tracking object, has escaped from the server 300, the last departure location is transmitted from the server 300, so that the guardian or the manager can quickly locate the location by searching the surroundings. .

본 발명은 상기와 같은 구조물(500)이 위치 추적 대상 구역에 소정 간격마다 설치되는 것을 특징으로 한다. 특히 해변의 경우에는 도 2에 도시된 바와 같이 해안선을 따라서 RFID 리더(200)를 포함하는 구조물(500)이 다수 설치됨으로써 백사장 내부에서 위치 추적 대상이 되는 어린아이 등의 위치를 정확하게 파악하도록 할 뿐만 아니라 바닷물에 빠진 아이의 위치까지도 추적할 수 있는 효과가 있다.The present invention is characterized in that the structure 500 is installed at predetermined intervals in the location tracking target area. Particularly, in the case of the beach, as shown in FIG. 2, a plurality of structures 500 including the RFID reader 200 are installed along the coastline to accurately determine the position of a child, etc., which is a location tracking target in the white sand. It also has the effect of tracking the location of the child in the sea.

RFID 리더(200)를 포함한 구조물(500)의 위치 및 간격은 위치 추적 대상이 되는 구역의 상황에 따라 적절하게 적용할 수 있으며, 해변과 같이 많은 인파를 수용해야 하는 곳에서는 내부에는 설치하지 않고 해당 구역의 둘레 부분에만 설치할 수도 있다.The location and spacing of the structure 500 including the RFID reader 200 may be appropriately applied depending on the situation of the area to be tracked, and in places where a large number of crowds are to be accommodated, such as a beach, the corresponding location is not installed. It may be installed only at the perimeter of the space.

그리고 상기 구조물(500)에 포함된 RFID 리더(200)와 디스플레이(600) 등에는 전력이 공급되어야 하는데, 케이블을 통해 유선으로 전력을 공급할 수도 있으나, 해변과 같이 유선으로 전력을 공급하는 것이 용이하지 아니한 경우에는 무선으로 전력을 공급하거나 자가 발전 방식으로 전력을 생산하는 방법을 사용할 수 있다.In addition, the RFID reader 200 and the display 600 included in the structure 500 need to be supplied with electric power. The electric power may be supplied by wire through a cable, but it is not easy to supply electric power by wire like a beach. If not, it can be powered wirelessly or self-generated.

무선으로 전력을 공급하는 방법의 경우에는 전자기 유도현상을 이용하는 방법을 검토해 볼 수 있다. 다만 무선 전력 공급의 경우 전자기파에 의한 인체 영향 등을 고려해야 하므로 수많은 인파가 몰리는 해변에서 사용하기에는 적합하지 않을 수 있다.In the case of wirelessly supplying power, a method of using electromagnetic induction may be considered. However, the wireless power supply may not be suitable for use on a beach with a large number of crowds because it is necessary to consider the influence of the human body due to electromagnetic waves.

따라서 본 발명은 이러한 문제를 고려하여 자가 발전 방식으로서 태양광 발전이나 풍력 발전 등을 이용하여 전력을 자체적으로 생산하여 사용하도록 한다.Therefore, the present invention is to take into account this problem to produce and use the power itself by using solar power or wind power generation as a self-generation method.

상기 태양광 발전의 경우에는 도 4에 도시된 바와 같이 구조물(500)의 외주면에 다수의 솔라셀(700)을 배치하고 이를 통해 구조물(500) 내부의 배터리(800)를 충전한다.In the case of the photovoltaic power generation, as shown in FIG. 4, a plurality of solar cells 700 are disposed on the outer circumferential surface of the structure 500, and the battery 800 inside the structure 500 is charged therethrough.

상기 풍력 발전의 경우에는 도 5에 도시된 바와 같이 상기 구조물(500) 상부에 지주탑(910)과 로터(920)를 포함하는 소정의 풍력발전장치(900)를 설치함으로써 구조물(500) 내부의 배터리(800)를 충전하게 된다.In the case of the wind power generation as shown in FIG. 5 by installing a predetermined wind power generator 900 including the holding tower 910 and the rotor 920 on the structure 500 above the structure 500 The battery 800 is charged.

한편, 상기 구조물의 상부에는 상기 휴대용 단말기를 이동통신서비스에 연결하기 위한 기지국(미도시)이 설치될 수 있다.On the other hand, a base station (not shown) for connecting the portable terminal to the mobile communication service may be installed on the upper portion of the structure.

일반적으로 기지국은 핸드폰이나 스마트폰과 같은 휴대용 단말기(400)와 이동통신서비스 사이에서 신호를 중계하는 역할을 하는 것으로서 소정의 기지국 안테나와 증폭기 등으로 구성된다. 특히, 해변가는 기지국이 설치되기 어려운 환경이기 때문에 해변가에서 휴대용 단말기(400)의 신호 수신율이 저조하여 통화 품질이 떨어지고 통화 도중 자주 끊기게 되는 현상이 발생하였다. 본 발명에서는 이러한 문제점을 개선하기 위하여 상기 구조물의 상부를 이용하여 기지국을 설치함으로써 휴대용 단말기(400)의 통화 품질을 향상시킬 수 있도록 한다. 기지국에 필요한 전기는 상기에서 검토한 풍력 발전 또는 태양광 발전을 이용하여 획득할 수 있다.In general, the base station plays a role of relaying a signal between a mobile terminal 400 and a mobile communication service such as a mobile phone or a smart phone, and includes a predetermined base station antenna and an amplifier. In particular, since the beach is an environment in which the base station is difficult to install, there is a phenomenon that the signal reception rate of the portable terminal 400 is low at the beach, resulting in poor call quality and frequent disconnection during the call. In the present invention, to improve this problem, by installing a base station using the upper portion of the structure to improve the call quality of the portable terminal 400. The electricity required for the base station can be obtained by using the wind power generation or solar power generation discussed above.
