EMERGENCY ALARM SYSTEM USING WIRELESS SIGNAL

摘要

PURPOSE: An emergency signal system using a wireless signal is provided to perceive a location and an ID(Identification) of a wireless terminal user. CONSTITUTION: Cells have specific locations by being divided into determined sections. A transmitter(100) is installed to each cell, and delivers signals including cell identifying signals corresponding to the specific locations. A wireless terminal(110) mounts a self specific identifying signal, and transmits the self specific identifying signal to the transmitter(100), or transmits a signal including the cell identifying signals and the self specific identifying signals. A control center(120) equips an analyzer. The analyzer receives the signals transmitted from the transmitter(100) or the wireless terminal(110), and analyzes the specific identifying signal of the wireless terminal(110) and the cell location identifying signal, then decides an ID(Identification) and a location of a wireless terminal user.
