Abstract:
The unmanned flying body is provided with a gas detector, a distance meter, and an altitude controller. The gas detector emits diagonally downward to the forward side in a moving direction of the unmanned flying body a detecting light frequency-modulated by a predetermined modulation frequency setting a predetermined frequency as a central frequency. The gas detector receives the light, returned from a measurement target to which the detecting light is emitted (an area on a pipe member for transferring gas, irradiated with the detecting light), as first light. The measurement target is checked for gas leakage based on the received first light. The distance meter measures the distance between the gas detector and the measurement target. The altitude controller controls the flight altitude of the unmanned flying body based on the measured distance.

Claim (Index 1):
A gas detection device for detecting from above gas leakage from a pipe member extending in a predetermined direction for transferring gas, the device comprising:\n an unmanned flying body; a gas detector provided in the unmanned flying body and configured to emit a detecting light diagonally downward to a forward side in a moving direction of the unmanned flying body to a measurement target, which is checked for gas leakage, on the pipe member extending in the predetermined direction, receive a light returned from the measurement target, to which the detecting light is emitted, as first light, and check the measurement target for gas leakage based on the received first light, the detecting light being frequency-modulated by a predetermined modulation frequency setting a predetermined frequency as a central frequency; a distance meter provided in the unmanned flying body and configured to measure a distance between the gas detector and the measurement target; and a hardware processor that is provided in the unmanned flying body and caused to control flight altitude of the unmanned flying body based on the distance measured by the distance meter.
