Embodiment 1

[0052] figure 1 The basic structural diagram of the airborne indoor gas telemetry system of the embodiment of the present invention is schematically given, as figure 1 As shown, the airborne indoor gas telemetry system includes:

[0053] Airborne follow-up device, the airborne follow-up device includes:

[0054] rotorcraft;

[0055] A first light source, such as a semiconductor laser; the first light source is used to emit a positioning beam; the first light source can be arranged on the roof of the monitoring vehicle;

[0056] At least three detectors, the at least three detectors are isolated from each other and arranged on the rotor UAV, respectively receive the light intensity of the positioning beam, and transmit it to the comparison module;

[0057] A comparison module, the comparison module is used to compare the light intensities received by at least three detectors respectively, and the deviation between the light intensities is transmitted to the control module; ...

Embodiment 2

[0082] An application example of the remote measurement system and method according to Embodiment 1 of the present invention in the detection of natural gas leakage in rooms on each floor of a residential building.

[0083] In this application example, the first light source adopts a laser and is installed on the roof of the monitoring vehicle; at least three detectors adopt four, are isolated from each other, and are symmetrically distributed (four-quadrant distribution), and are installed on a multi-rotor UAV; the telemetry device is only One of the light sources (i.e. the second light source) uses a DFB laser, and the wavelength of the measuring light includes 1651nm (corresponding to the absorption line of methane); the driving circuit of the laser outputs pulse current signals and continuous current signals to the laser, so that the laser emits The pulsed light signal for distance measurement and the continuous light signal for detection of absorption; the only detector in...

Embodiment 3

[0103] The gas remote measurement system and method of the embodiment of the present invention are different from the second embodiment in that there are at least three detectors, and the angle between adjacent detectors is 120 degrees, and they are separated.
