Location tracking system
First Claim
1. A location tracking system in whicha main terminal mounted with a first wireless communication module and a plurality of sub-terminals, each of which is mounted with a second wireless communication module and has an identification code, are configured to conduct wireless communication within a preset range,the main terminal includes a deviation display part that displays the plurality of sub-terminals having the identification code in a different color when at least one of the sub-terminals deviates from a preset safety range and enters a deviation boundary range, andeach sub-terminal includes a warning sound output part that receives a control signal sent from the main terminal to output a warning sound when the deviation display part displays the deviation of the sub-terminal,wherein:
- the deviation display part includes a plurality of lamps that are displayed as numbers on a touch screen of the main terminal, and each of the lamps corresponds to one of the plurality of sub-terminals;
the plurality of lamps are arranged in rows and columns so as to be displayed on the touch screen of the main terminal in a manner that is neutral to distances of the corresponding sub-terminals from the main terminal;
each of the plurality of lamps is turned green or blue when the corresponding sub-terminal is within the preset safety range under the control of the first micro-computer, and red when the corresponding sub-terminal is within the deviation boundary range beyond the preset safety range under the control of the first micro-computer;
the main terminal further includes an enter key that outputs a signal for instructing the first micro-computer to output a control signal for a warning sound to all of the sub-terminals of which the corresponding lamps are turned red; and
each sub-terminal further includes a second micro-computer that controls the second wireless communication module and the warning sound output part when receiving the control signal for the warning sound from first wireless communication module by wireless.

Abstract
Provided is a location tracking system in which a main terminal and a plurality of sub-terminals are configured to conduct wireless communication within a preset distance range which the sub-terminals should keep from the main terminal, and in which the main terminal has a plurality of display parts displaying the respective sub-terminals, whereas each sub-terminal has a warning sound output part. Thereby, when any sub-terminal deviates from a boundary of the preset distance range, the sub-terminal deviating from the boundary of the preset distance range is configured to be immediately displayed on the main terminal and to output a warning sound. Thus, during an outdoor group event (e.g., domestic or foreign travel, mountain climbing, an excursion, etc.), both a leader and participants are able to easily recognize the deviation from the boundary, and any participant can be prevented from becoming accidentally separated from a group. Further, a schedule for the group event, information (e.g. tourist resort) corresponding to the schedule, and a list of the participants are stored in the main terminal and each sub-terminal so as to be readable. The leader and the participants are able to easily read the schedule for the group event at any time, and the participants can maintain closer familiarity through the reading of information among them.
