RESCUER LOCATOR USING BIDIRECTIONAL SIGNAL TRANSMITTER

摘要

A rescuer locator using a bidirectional signal transmitter wherein each rescuer who is dispatched to a disaster spot so as instantly recognize a dangerous state of other rescuers who had been dispatched for rescue or fire suppression, carries a signal transmitter which may be taken by another rescuer when in emergency and may be configured to ask help in such a way to transmit an emergency signal to a base unit installed at a control vehicle, and the signal transmitter equips with a motion detection sensor so as to automatically transmit signals to the base unit depending on the movements of a rescuer who is dispatched to a disaster spot, thus checking in real time a dangerous state of each rescuer.

1. A rescuer locator using a bidirectional signal transmitter, comprising:
a signal transmitter which includes at least one among a light emitting unit, a sound output unit and a vibration module, and a center button unit, a chip set, a signal transmission and reception module, a motion detection sensor and a timer and operates by a battery; a base unit which includes at least one among a display unit, a center button unit, a direction key unit, a sound output unit, a light emitting unit and a vibration module, and a chip set, and a signal transmission and reception module and operates by a battery; and an RFID tag and an RFID reader which are configured to display the position distribution of rescuers on the display unit of the base unit, in which the signal transmitter and the base unit operate with an RFID provided at a disaster spot, wherein a danger signal is wirelessly transmitted using a signal transmission and reception module and a center button unit which are disposed at the signal transmitter and the base unit, thus operating a sound output unit, a light emitting unit and a vibration module which are provided at the base unit or the signal transmitter, and in the signal transmitter, if there is not any motion for a predetermined time in a rescuer who has been dispatched to a disaster spot, a danger signal is first transmitted automatically from the signal transmission and reception module to the base unit at a time interval set by a chip set disposed at the signal transmitter, thus operating the display unit, the sound output unit, the light emitting unit or the vibration module which are provided at the base unit, and if any motion is not detected in a corresponding rescuer, the sound output unit, the light emitting unit or the vibration module of the base unit and the signal transmitter are second operated, thus searching the rescuer.
