The present invention relates to a children tracking terminal system and a method using the same. The children tracking terminal system comprises a missing child prevention main terminal and a sub-terminal each having Bluetooth and GPS communication means. The children tracking terminal system computes the movement and direction of the main terminal and the sub-terminal by using the location and direction data of a GPS when a reception level between the main terminal and the-sub terminal is detected to be lower than a reference level by using Bluetooth. The children tracking terminal system of the present invention can display the movement and direction of the main terminal and the sub-terminal on a display in real time by using the location and direction data of the GPS when the reception level between the main terminal and the sub-terminal is detected to be lower than the reference level by using Bluetooth or Wi-Fi direct between the main terminal and the sub-terminal and can display a distance according to the location and direction of the main terminal and the sub-terminal on the display in real time. |
