GAS-LEAKAGE ALARMING SYSTEM, CAPABLE OF DETECTING THE GAS LEAKAGE FROM A VEHICLE

摘要

PURPOSE: A gas-leakage alarming system is provided to enhance the measuring efficiency of a sensor and to extend the lifespan of the sensor since the sensor is formed to be able to measure every certain cycle.;CONSTITUTION: A gas-leakage alarming system comprises a first sensor(100), a second sensor(200), an alarming unit(300), and a control unit(400). The first sensor measures the amount of fuel flowing into from a gas tank, every certain cycle. The second sensor measures the amount of fuel consumed by the engine, every certain cycle. The alarming unit sounds the alarm if gas is leaked. The control unit measures the difference between the amount of fuel flowing into from a gas tank and that of fuel consumed by the engine. The control unit sounds the alarm if the difference is over a reference value. The control unit decreases the measured cycle of the first and second sensors if the number of alarm is over a certain value.;COPYRIGHT KIPO 2011
