摘要：
The present invention relates to a device to automatically measuring a tree girth and a tree management system capable of efficiently manage trees grown by being dispersed in an extensive area using a measurement device. The device of the present invention comprises: a girth measurement unit which detects an increase and decrease of the tree girth as an angle value； a calculation means which calculates the tree girth by a predetermined algorithm by receiving the angle value from the girth measurement unit, outputting the calculated tree girth value； a storage means which stores the calculated tree girth value of the calculation means； and a transmission means which transmits the calculated tree girth value of the calculation means to the outside. The girth measurement unit outputs an angle value in accordance with a girth size of the tree by comprising: a reel which has a magnet attached to one side； a pulling means which rotates the reel in a forward direction if the tree girth increases as one end is wound on the reel and an other end surrounds the tree girth； a rewinding spring which applies elasticity to rotate the reel in a reverse direction； and an angle sensor which senses a rotational angle of the magnet. According to the present invention, the tree girth automatic measurement device has the effects of measuring the tree girth based on a mechanical composition, and using a battery for a long time by only being waken up during the measurement after a sleep mode； and reducing manufacturing costs by being formed in a simple structure.본 발명은 나무의 둘레(Tree Girth)를 자동으로 측정하는 장치와 이를 이용하여 광범위한 영역에 분산되어 재배되는 나무들을 효율적으로 관리할 수 있는 수목 관리 시스템에 관한 것이다. 본 발명의 장치는, 나무둘레의 증감을 각도값으로 검출하기 위한 둘레측정부와, 둘레측정부로부터 각도값을 입력받아 소정 알고리즘에 따라 나무둘레를 계산하고, 산출된 나무둘레값을 출력하는 연산수단과, 연산수단의 산출된 나무둘레값을 저장하는 저장수단과, 연산수단의 산출된 나무둘레값을 외부로 전송하는 전송수단을 포함하고, 둘레측정부는 일측에 마그넷이 부착된 릴과, 일단이 릴에 권취됨과 아울러 타단이 나무둘레를 감싸 나무둘레가 늘어나면 상기 릴을 순방향으로 회전시키기 위한 당김수단과, 릴을 역방향으로 회전시키기 위한 탄성력을 인가하는 리와인딩 스프링과, 마그넷의 회전각도를 감지하기 위한 각
