FIRE DETECTOR USING ELECTRONIC NOSE SENSOR, IN WHICH PREVIOUS ALARM IS EASILY REALIZED

摘要

PURPOSE: A fire detector using an electronic nose sensor is provided to minimize the damage by performing early suppression and looking into causes of the fire. CONSTITUTION: A fan motor(10) includes a suction part(12) for collecting air. A sensor array(20) includes a plurality of sensors in order to identify a predetermined pattern of a smell through the suction unit. A detector/amplifier(30) changes the identified smell as data and detects and amplifies data signals of the identified smell. An A/D converter(40) is used for converting the detected data signals to electric signals. A storage unit(50) stores various patterns of fire smells as reference values. A display(60) is used for displaying present states of the sensors. An alarm(70) is used for alarming a fire according to a contact state of a relay. A microcomputer(80) controls the fan motor and the display, determines a state of the fire by comparing the detected signal pattern with the stored reference values, and adjusts the contact of the relay.
