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

摘要

Purpose: being arranged to minimize damage using a fire detector of an electronic nose sensor, by executing the inhibition of early stage and investigating fiery reason. Construction: a fan motor (10) includes a suction part (12) for collecting air. One sensor array (20) includes multiple sensors, in order to identify a predetermined pattern of a smell by aspirator. One detector/amplifier (30) change determining smell be data and detect and amplify confirmation smell data signals. One A/D converter (40) is used to detected data signal be converted to electric signals. Various patterns of one storage unit (50) as reference value storage fire smell. One display (60) is used to show the present state of sensor. One alarm (70) is used for a fire of alarming according to a contact state of a relay. One microcomputer (80) control fan motor and display determine that the state of fire has the detected signal mode of reference value of storage by comparing, adjust the contact of relay.
