and S110, flying the unmanned aerial vehicle carrying the hollow reflector array into a hazardous gas cloud cluster and hovering the unmanned aerial vehicle.
Specifically, Hollow mirrors (Hollow reflexers) are mirrors that can turn an incident light beam 180 ° back and are completely insensitive to the position and angle of the incident light, and are also called corner mirrors and Hollow conical mirrors. The hollow mirror, in which the light beam is externally reflected on all surfaces, is particularly advantageous because it avoids problems of material absorption, wavelength dispersion or optical path change, which are caused by a conventional glass retroreflector. As shown in fig. 2, before actual detection, a takeoff unmanned aerial vehicle (for example, 100 meters) at a certain distance flies into the hazardous gas cloud cluster with the hollow mirror array, and hovers in the hazardous gas cloud cluster.
And S120, the host machine transmits first infrared laser to the hollow reflector array by using the centering telescope, the hollow reflector array receives second infrared laser reflected by the first infrared laser to the dangerous gas cloud cluster and the dangerous gas cloud cluster, and the hollow reflector array reflects the second infrared laser to the detector of the host machine.

A tripod head is arranged between the main machine and the tripod, and a centering telescope is arranged on the tripod head and used for aiming at the emission direction of the infrared laser. When the unmanned aerial vehicle hovers in the dangerous gas cloud cluster, an operator adjusts a knob of the centering telescope to enable the center of a cross shape of a lens of the centering telescope to just fall on the middle position of a hollow retro-reflector array, a host machine transmits first infrared laser to the hollow retro-reflector array, the hollow retro-reflector array receives the first infrared laser and reflects the first infrared laser to the dangerous gas cloud cluster, when a chemical gas cloud cluster in a detection area reaches the minimum detection limit, gas molecules selectively absorb infrared rays with certain wavelengths, so that transition of vibration energy level and rotation energy level in the gas molecules to be detected is caused, second infrared laser reflected by the dangerous gas cloud cluster is different from the first infrared laser, the hollow retro-reflector array receives the second infrared laser reflected by the dangerous gas cloud cluster, and the second infrared laser is reflected to a detector of the host machine by the hollow retro-reflector array.
As an alternative embodiment, after the hollow mirror array reflects the second infrared laser light back to the detector of the host, the method further includes: the unmanned aerial vehicle moves a preset distance to any direction around; and the host machine reuses the centering telescope to transmit the first infrared laser to the hollow reflector array until the unmanned aerial vehicle finishes the flight detection of the preset area.

And S130, analyzing the spectral information of the second infrared laser by the host to obtain the type and concentration of the hazardous gas.
Specifically, after a detector of the host machine receives a second infrared laser, the host machine detects the condition that the second infrared laser is absorbed by hazardous gas to obtain an infrared absorption spectrum curve, wherein the abscissa of the infrared absorption spectrum curve is the wave number of the infrared laser, and the ordinate of the infrared absorption spectrum curve is the absorbance of the infrared laser after passing through a gas cloud cluster; and the host machine obtains the type of the hazardous gas according to the position of the absorption peak of the infrared absorption spectrum curve, and obtains the concentration integral of the hazardous gas according to the absorbance of the absorption peak. For example, when gas leakage occurs in toluene in a chemical industry park, the first infrared laser enters into hazardous gas and then reaches 3000cm-1，1460cm-1And 1380cm-1Has obvious absorption peak to form a second infrared laser reflected back to the host, and the host detects the infrared absorption to obtain the infrared absorption spectrum curve of toluene at 3000cm as shown in FIG. 3-1，1460cm-1And 1380cm-1The toluene gas is judged to be toluene gas according to the position of absorption, and the integral value of the concentration is calculated according to the degree of absorption.
As an optional embodiment, because detect the gas kind and the concentration distribution of danger gas cloud group, need unmanned aerial vehicle to hover and acquire infrared laser reflection in a plurality of positions and gather, consequently, accomplish after the flight detection to predetermineeing regional at unmanned aerial vehicle, the host computer gathers the kind and the concentration distribution that obtain the danger gas of predetermineeing regional according to the infrared absorption spectrum curve analysis of corresponding unmanned aerial vehicle each position. Further, because the problem of wind current, gas can drift along with the wind, and the host computer can be gathered according to the infrared absorption spectrum curve that corresponds each position of unmanned aerial vehicle and wind speed wind direction analysis at that time and obtain the kind and the concentration distribution of presetting regional dangerous gas, and the host computer transmits the kind and the concentration distribution of presetting regional dangerous gas to analysis display terminal and shows the concentration distribution diagram of dangerous gas. Under general conditions, the closer to the leakage point, the higher the concentration, thereby analyzing possible leakage points and variation trends, realizing real-time identification and tracking of hazardous gas and facilitating the field supervision personnel to take corresponding measures.
According to the technical scheme of the embodiment of the invention, the unmanned aerial vehicle is adopted to carry the hollow reflector array, so that real-time identification and tracking of the dangerous gas cloud cluster are realized, and hundreds of dangerous gases can be detected simultaneously. When the chemical gas in the monitoring area reaches the minimum detection limit, the device can accurately identify the type and the path integral concentration of the gas, display the detection result, move the unmanned aerial vehicle carrying the hollow retro-reflector left and right in the direction perpendicular to the light path, find the optimal retro-reflection point through the centering device, detect the concentration integral values on a plurality of light paths step by step, and then automatically judge the concentration distribution of the gas cloud cluster according to the detection result of the plurality of points, thereby analyzing possible leakage points and change trends, and realizing real-time identification and tracking of the hazardous gas.
