GAS DETECTION SYSTEM

摘要

A gas detection system includes: a gas detection radio wave transmission/reception unit (11) having at least one gas detection radio wave transmission means (111) and gas detection radio wave reception means (112); a reference radio wave transmission /reception unit (12) having at lest one reference radio wave transmission means (121) for emitting a reference radio wave and the same number of reference radio wave reception means (121) as the number of reference radio wave transmission means (121), for receiving the reference radio wave without passing through the gas detection object region; radio wave phase detection means (13) for detecting a phase difference between the gas detection radio wave received by the gas detection radio wave reception means and the reference radio wave received by the reference radio wave reception means; and gas-in-object region detection means (14) for detecting whether gas exists in the gas detection object region according to the phase difference detected by the radio wave phase detection means.
