Background
The troposphere and stratosphere are the main areas of the earth's atmosphere, the areas of concentration where meteorological activity occurs. The troposphere is the layer of the atmosphere closest to the ground, and the mass of the troposphere accounts for about 75 percent of the total mass of the atmosphere, almost all water vapor and aerosol are concentrated in the troposphere, and the atmospheric process of the troposphere is closely related to the production and the life of human beings. The stratosphere is an airspace which is concerned by space scientific research and near-earth space flight in recent years, and the airspace has the advantages of dry atmosphere, less impurities, high visibility, less cloud and rain, stable temperature and zero humidity.

The high-altitude atmospheric motion is a main factor influencing the flight of the powered low-speed aircraft, and the detection of the characteristics of the high-altitude atmospheric motion has important significance on the design and flight control of the powered low-speed aircraft. The high-altitude atmosphere and the near-ground atmosphere have obvious differences in density, components, motion states and the like, the difference is larger when the heights are higher, the atmospheric motion characteristic detection means in the prior art mainly depends on Doppler laser radar remote sensing, and the remote sensing mode comprises space-based fixed track scanning and ground-based fixed point detection wind field vertical profile. Due to the particularity of the high-altitude atmosphere, the ground conventional atmosphere motion detection means is difficult to be suitable for the high-altitude atmosphere.
Therefore, how to realize the detection of the high-altitude atmospheric motion has become an urgent problem to be solved in the industry.

Specifically, the high-altitude atmospheric motion detection system described in the embodiment of the present invention is hung outside the powered low-speed aircraft, and the high-altitude atmospheric motion detection system is directly exposed to the high-rise atmosphere, so that the marker can be effectively and sufficiently mixed with the atmosphere after being released, and the marker mixed with the atmosphere can be directly captured.
The marker described in the embodiments of the present invention may refer to a marker which is gaseous or suspended particles at a low temperature, can be released and suspended by electronic control, and is easily detected, such as colored smoke or the like.
The detection device described in the embodiments of the present invention may refer to a device for identifying a marker corresponding to the marker, and the observation data of the device may be used to invert the motion state of the marker, such as a spectrum detection device, an ultrasonic detection device, or a visual sensor.
The marker detection described in the embodiment of the present invention specifically means that the motion information of the marker can be converted by imaging the marker at a high frame rate, fixing the inter-frame time, and changing the position of the marker in the adjacent frame images.
Because the detection device is rigidly connected with the dynamic low-speed aircraft and has the same motion state with the dynamic low-speed aircraft, the motion information of the marker detected by the detection device is the relative motion state of the detection device and the dynamic low-speed aircraft, but not the absolute motion state. The absolute motion state of the marker motion information can be obtained by compensating and correcting the relative motion state of the marker through the absolute motion state of the aircraft.
The embodiment of the invention obtains the atmospheric motion detection information through the marker motion information, and particularly means that the marker motion information is obtained by compensating and correcting the marker motion information through the flight speed of the dynamic low-speed aircraft.
According to the embodiment of the invention, the high-altitude atmospheric motion detection system is hung outside the low-speed aircraft and directly exposed in the high-rise atmosphere, the marker is released into the atmosphere through the marker release device according to the marker release instruction, and after the marker is fully mixed in the atmosphere, the motion state of the marker and the motion state of the atmosphere are converged under the driving of atmospheric motion, so that the motion state of the marker is detected through the detection device, the high-altitude atmospheric motion detection can be indirectly realized, and the problem that the high-altitude atmospheric motion detection cannot be effectively realized in the prior art is solved.

S1 is a logic input for controlling the marker releasing means to release the marker, S2 is a logic input for the detecting means to detect the marker, VIN and GND are power inputs, D1 is the marker releasing means, and D2 is the detecting means.
Specifically, the control device applies TTL level to the S1 interface, the marker release device D1 is turned on at this time, when the detection device D2 collects marker movement information, the observation result is sent to the control device through the S2 interface, the control device cancels the TTL level applied to the S1 interface, stops releasing the marker, and one-time observation is finished.
According to the embodiment of the invention, the detection devices and the marker release devices which are arranged differently can more effectively capture the motion information of the released marker, so that the realization of high-altitude atmospheric motion detection is facilitated.
On the basis of the above embodiment, the marker releasing device is a solid electronic ignition smoke generator, and the detecting device is a visual sensor.
The solid-state electronic ignition smoke generator described in the embodiment of the invention releases high-concentration red smoke. The fuming device consists of a fuming chemical agent, a combustion improver and an electronic igniter, fuming under the conditions of thin oxygen and low temperature can be realized through electronic control, and the chemical agent can be potassium perchlorate, rose essence, antimony trisulfide and Arabic gum.
According to the embodiment of the invention, the solid-state electronic ignition smoke generator can realize smoke generation under the conditions of thin oxygen and low temperature through electronic control, the release of the marker can be realized under the condition of high-altitude atmosphere, and the detection of high-altitude atmospheric motion is facilitated.
Fig. 5 is a schematic flow chart of a high-altitude atmospheric motion detection method according to an embodiment of the present invention, as shown in fig. 5, including:
step S1, obtaining a marker release instruction according to the control device;
step S2, the marker releasing device releases a plurality of markers into the atmosphere according to the marker releasing instruction and the preset time sequence;
and step S3, after the multiple markers are fully mixed with the atmosphere, detecting the markers by the detection device to obtain the marker motion information, so as to obtain the atmosphere motion detection information according to the marker motion information.
Specifically, the instruction for releasing the marker according to the preset time sequence in the embodiment of the present invention is to release the marker into the atmosphere at intervals according to a preset time, where the preset time may be determined according to a time when the detection device detects the marker in the historical experimental data.
Specifically, in the embodiment of the present invention, when the detection device detects the marker, it is further required to avoid the situation that the concentration of the marker is too low, and when the detection device detects that the concentration of the marker is too low, that is, the number of the markers is less than the preset value, information is fed back to the control device, so that the control device sends the marker release instruction again.
The marker detection described in the embodiment of the present invention specifically means that the motion information of the marker can be converted by imaging the marker at a high frame rate, fixing the inter-frame time, and changing the position of the marker in the adjacent frame images.
The embodiment of the invention obtains the atmospheric motion detection information through the marker motion information, and particularly means that the marker motion information is obtained by compensating and correcting the marker motion information through the flight speed of the dynamic low-speed aircraft.
According to the embodiment of the invention, the high-altitude atmospheric motion detection system is hung outside the low-speed aircraft and directly exposed in the high-rise atmosphere, the marker is released into the atmosphere through the marker release device according to the marker release instruction, and after the marker is fully mixed in the atmosphere, the motion state of the marker and the motion state of the atmosphere are converged under the driving of atmospheric motion, so that the motion state of the marker is detected through the detection device, the high-altitude atmospheric motion detection can be indirectly realized, and the problem that the high-altitude atmospheric motion detection cannot be effectively realized in the prior art is solved.
On the basis of the above embodiment, the step of detecting the marker by the detection device to obtain the motion information of the marker specifically includes:
performing high frame rate imaging with fixed inter-frame time on the marker through the detection device to obtain a plurality of detection picture information;
and analyzing the position change of the marker on the plurality of detection picture information to obtain the motion information of the marker.
Specifically, because the high frame rate imaging shot in the embodiment of the invention is fixed in time between frames, a series of continuous detection image information in time sequence can be obtained; the specific step of analyzing the position change of the marker on the plurality of detection picture information is to convert the position change of the marker in the adjacent frame images into marker motion information.
According to the embodiment of the invention, the position change of the marker in the adjacent frame image can be converted to obtain the marker motion information through the high frame rate imaging with fixed inter-frame time, so that the analysis of the marker motion information is effectively realized.
On the basis of the above embodiment, the step of obtaining atmospheric motion detection information according to the marker motion information specifically includes:
acquiring flight speed information of a high-altitude atmospheric motion detection system;
and carrying out compensation correction on the marker movement information according to the flight speed information of the high-altitude atmospheric movement detection system to obtain atmospheric movement detection information.
In the embodiment of the invention, the high-altitude atmospheric motion detection system is rigidly connected with the high-altitude atmospheric motion detection system, so that the flight speed information of the high-altitude atmospheric motion detection system is the same as the flight speed of the dynamic low-speed aircraft, and the flight speed information of the high-altitude atmospheric motion detection system can be obtained by means of satellite positioning technology, ground remote sensing and the like.
According to the embodiment of the invention, the marker motion information is compensated and corrected through the flight speed information of the high-altitude atmospheric motion detection system, so that more accurate atmospheric motion detection information is obtained.
On the basis of the above embodiment, before the step of detecting the markers by the detecting device after the plurality of markers are sufficiently mixed with the atmosphere, the method further includes:
acquiring diffusion acceleration information of the marker according to the detection device;
and judging the mixing condition of the marker and the atmosphere according to the diffusion acceleration information of the marker.
Specifically, after the marker is released, a viscous force is generated in the fusion process of the marker and the atmosphere, the viscous force between fluids is in direct proportion to the flow velocity gradient, and when the velocity difference is large, the viscous force is large, and the generated acceleration is also large. In the acceleration movement of the marker due to viscous force, the acceleration is gradually reduced along with the reduction of the flow velocity gradient, when the flow velocity gradient between the marker and the atmospheric flow velocity is 0, the acceleration disappears, and the marker and the atmospheric movement converge, namely, the marker is fully mixed. The motion state of the marker is observed in real time through the detection device, and when the marker gradually transits from acceleration to uniform motion, the marker and the atmosphere can be judged to be fully mixed.
According to the embodiment of the invention, the marker detection is carried out after the marker is judged to be fully mixed with the atmosphere, so that the monitoring accuracy and reliability are ensured.
