LOCATION TRACE AND RELIEF SYSTEM USING A MOBILE TERMINAL FOR NOXIOUS GAS DETECTION, ESPECIALLY CONCERNED WITH INSTALLING A GAS DETECTION SENSOR IN A MOBILE TERMINAL WITH AN A/D CONVERTER IN ORDER TO DETECT NOXIOUS GAS

摘要

PURPOSE: A location trace and relief system using a mobile terminal for noxious gas detection is provided to minimize the rate of deaths from gas suffocation by attaching a gas detection sensor to a mobile terminal, converting gas detection into a signal through an A/D(Analog-to-Digital) converter, and announcing it to the mobile user. CONSTITUTION: A noxious gas detection sensor is installed in a mobile terminal. If noxious gas is detected, an A/D converter converts it into a signal and forwards the converted signal to the DSP(Digital Signal Processor) of the mobile terminal. The DSP executes various analyses for the detected gas through the forwarded signal and announces it to the mobile user with a beeper sound, vibration, or an indication on the LCD screen.
