The present invention includes a GPS module communicating with a GPS satellite a post location setting unit which receives the coordinate data of a present location from the GPS module when a post location setting key is inputted and sets the information of the locations where posts are installed an electronic fence setting unit which calculates the coordinate data of a line connecting the posts based on the information of the locations where the posts are installed and sets the information of the location where an electronic fence is installed and a stimulation generating unit which receives the coordinate data of the present location from the GPS module at predetermined time intervals and generates at least one among electronic stimulation and vibration or sounds if the location where the electronic fence is installed is within a predetermined distance from the present location. The present invention sets the electronic fence based on the GPS information, generates sounds when animals approach the electronic fence, and applies vibration or electronic stimulation to the animals, thereby controlling the animals not to be escaped from a predetermined area and informing a user about the states of the animals. Furthermore, the present invention registers the locations of the virtual posts based on the GPS information and sets a boundary of an active region of animals, thereby reducing expenses for installing the fence and maintenance and being easily carried.COPYRIGHT KIPO 2014[Reference numerals] (210) Post location setting key (220) Post location inputting key (230) GPS module (240) Transmitting unit본 발명의 GPS위성과 통신하는 GPS모듈, 지주위치설정키가 입력되면 상기 GPS모듈로부터 현재 위치의 좌표데이터를 전달받아 지주가 설치된 위치정보로 설정하는 지주위치설정부, 상기 지주가 설치된 위치정보를 통해 지주 사이를 연결하는 선의 좌표데이터를 계산하여 전자울타리가 설치된 위치정보로 설정하는 전자울타리 설정부, 상기 GPS모듈로부터 일정시간 간격으로 현재 위치에 따른 좌표데이터를 수신하고, 상기 수신된 좌표 데이터와 상기 전자울타리로 설정된 위치정보가 일정 거리 이내이면 전기자극, 진동 또는 음향 중 적어도 하나를 발생시키는 자극 발생부를 포함한다.이를 통해 본 발명은 GPS 정보를 통해 전자울타리를 설정하고, 동물의 위치를 파악하여 동물이 전자울타리에 근
