Embodiment 1

[0041] Such as Figure 1-Figure 2 As shown, the single-line laser UAV gas detection system includes a ground control station 1 and a UAV terminal. The ground control station 1 is connected to the data transmission link 2 of the UAV terminal through a wireless communication module. The human-machine terminal includes a drone body and a detection device arranged in the drone body.

[0042] The detection device includes a semiconductor laser drive module 4, a flue 6, a laser transmitter 5, a photoelectric sensor 7 capable of measuring single-line laser spectrum data, a data collection module 8 and a gas data analysis and control module 3.

[0043] The semiconductor laser drive module 4 is arranged in the drone body and is connected to the gas data analysis and control module 3, and is used for injecting current into the laser transmitter 5 for driving and frequency modulation according to the signal sent by the gas data analysis and control module 3. The semiconductor laser drive modu...

Embodiment 2

[0069] Such as Figure 3 to Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the detection device further includes a beam splitter 12 and a verification sensor 11 arranged on the side of the flue 6 with the laser transmitter 5. The beam splitter 12 is provided at the emitting end of the corresponding laser transmitter 5. There are two output ends of the beam splitter 12, one is connected to the check sensor 11, the other is connected to the flue 6 and is connected to the The photoelectric sensor 7 is opposite, and the check sensor 11 is connected to the gas data analysis and control module 3. The single-line laser light emitted by the laser transmitter 5 enters the beam splitter 12 and is divided into two light paths. A laser beam is received by the calibration sensor 11, which is a photoelectric sensor that detects the frequency and intensity of the single-line laser. The other laser beam passes through the flue 6 to scan the gas in it and i...

The detection method disclosed by the invention has the advantages of no influence from background gas, dust and window pollution and capability of automatically revising the influence of temperature pressure on the measurement.

Description

Technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a single-line laser unmanned aerial vehicle gas detection system and a detection method thereof. Background technique [0002] At present, with the development of UAV technology, gas detection technology is also used in UAVs. This simplifies the test steps when facing some special scenes (such as high altitudes, disaster locations, etc.) gas measurement operations, while protecting the safety of workers. [0003] However, the current UAV gas detection technologies are all gas-sensitive detection methods. This type of method has large errors when operating in the flying environment of the UAV, and is easily affected by the environment. The instrument flue is easy to plug and leak. The equipment needs frequent maintenance and other issues. [0004] The utility model patent No. 201420103431.6 discloses an unmanned aerial vehicle-borne chemical gas detection system. Although the use...
