Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following detailed description of the various aspects of the present invention will be given with reference to the accompanying drawings. It should be understood that the various embodiments described below are for illustration only and are not intended to limit the scope of the present invention.
The typhoon information detector provided by the embodiment of the invention is a downward-projecting typhoon information detector and can be applied to stratospheric airships. Fig. 1 is a schematic view of an application scenario of a downcast typhoon information detector according to an embodiment of the present invention. As shown in fig. 1, the scene is a scene using a stratospheric airship launching detector, and the scene comprises a downcast typhoon information detector and a stratospheric airship. When the typhoon information detector is thrown, the downward throwing type typhoon information detector is hung on the stratospheric airship, the stratospheric airship flies to a designated throwing position above typhoons, and the downward throwing device is started to enable the detector to be separated from the stratospheric airship, and after the detector is separated from the stratospheric airship, the detector falls into typhoons to collect weather information in the typhoons. After the detector collects the weather information in the typhoon, the collected weather information can be sent to the information processing equipment, and the information processing equipment further analyzes the collected weather information to further study the physical process of typhoon weather.
Typhoon systems have a complex internal circulation structure with a diameter of 200-300 km and a height of about 15km, and the flying height of a general aircraft is difficult to reach above typhoons and requires a large take-off site. The stratospheric airship has the characteristics of high running height, vertical take-off and landing, long dead time, long hovering time or fixed point monitoring, can be lifted above typhoons by using a small take-off field, and is convenient to control the throwing height and the throwing position. However, as described above, the stratospheric airship has a limited load, and the conventional detector has an excessively large overall weight due to the use of a complicated ice crystal particle information acquisition device, and thus cannot be applied to a scene put in by the stratospheric airship.
The embodiment of the invention fully considers the overall weight of the detector, redesigns the detector structure and the collection mode of typhoon ice crystal particles, so that the detector has lighter overall weight and can be applied to the scene of stratospheric airship throwing.
Embodiment one
The present embodiment provides a typhoon information detector. Fig. 2 is a schematic diagram of the overall structure of a typhoon information detector according to an embodiment of the present invention. As shown in fig. 2, the typhoon information detector provided in this embodiment includes: a film float ball 110, and a main body detecting unit 120.
The membrane float ball 110 is a non-inflatable float ball, which is a standard ball type, pre-filled with gas for floating the probe inside the typhoon and adsorbing ice crystal particles inside the typhoon. The film float ball 110 is transparent and has an observation area 111 disposed thereon.
The body probe 120 is hermetically connected to the membrane float ball 110, with a first end 121 extending into the interior of the float ball 110 and a second end 122 remaining outside the float ball 110.
The main body detecting section 120 includes: an imaging device 210, and an information transmitting device 220.
The image capturing device 210 is disposed on the first end 121 of the main body detecting unit 120, and is configured to capture an optical image of the observation area 111.
The information transmitting means 220 is provided on the second end 122 of the main body detecting section 120 for transmitting the optical image of the observation area 111 to the information processing apparatus to acquire ice crystal particle information inside typhoons from the optical image of the observation area 111 by the information processing apparatus.
According to the typhoon information detector provided by the embodiment of the invention, the transparent film floating ball is adopted, the observation area is arranged on the film floating ball, the imaging device is used for shooting ice crystal particles adsorbed in the observation area, the overall weight of the detector for acquiring ice crystal particle information in typhoons can be reduced, and the detector can be used on stratospheric airships.
Wherein the film float ball 110 is used to float the probe and adsorb ice crystal particles inside typhoons, and is a non-inflatable float ball made of film material.
In practice, the observation region 111 may be placed on top of the thin film float sphere 110 to adsorb more ice crystal particles. The film float ball 110 may be made of a transparent polyester film (PET) material. The PET polyester film material has good adsorptivity and high transparency, can better adsorb ice crystal particles, and is convenient for shooting ice crystal particle information. The membrane float ball 110 may be provided as a standard ball type. The buoyancy around the standard spherical floating ball is balanced, and the standard spherical floating ball is not easy to topple in a complex circulation environment in typhoon, so that the detector can stably float in typhoon. The gas pre-filled inside the thin film float ball 110 may be an inert gas such as helium, hydrogen, etc. to improve safety while improving the float ability.
Second embodiment
In the above embodiment, the collected ice crystal particle information inside the typhoon may include: morphology information, concentration information, etc. of ice crystal particles. In one embodiment, the collected ice crystal particle information inside the typhoon may further include: dimensional information of ice crystal particles.
The present embodiment provides another typhoon information detector to collect the scale information of ice crystal particles inside typhoons. The entire structure of the typhoon information detector provided in this embodiment is substantially the same as that of the first embodiment, and is different from that of the first embodiment in that a scale grid is further provided on the observation area of the typhoon information detector provided in this embodiment.
Fig. 3 is a schematic view of an observation area of a typhoon information detector according to an embodiment of the present invention. As shown in fig. 3, in the present embodiment, since the scale grid is provided on the observation region 111, the captured optical image of the observation region 111 includes the scale grid image information of the observation region 111 and the ice crystal particle image information adsorbed to the observation region 111. The scale grid is a grid line marked with scales, and can be used for comparing with ice crystal particle information adsorbed on the observation area 111 to obtain the size information of the ice crystal particles. Thus, the size information of the ice crystal particles can be obtained from the scale grid image information of the observation region 111 and the ice crystal particle image information adsorbed to the observation region 111 in the optical image of the observation region 111. Where the ice crystal particles are typically in the millimeter scale, and correspondingly the smallest scale of the scale grid is below the millimeter scale, they may be imprinted on the observation region 111 using a microlithography process.
Specifically, during the process of the probe floating, the floating ball adsorbs ice crystal particles in the typhoon, and ice crystal particles are also adsorbed on the observation area 111. When the observation region 111 is set to be transparent and a scale grid is set thereon, ice crystal particles adsorbed to the observation region 111 and the scale grid around the ice crystal particles can be photographed through the transparent observation region 111 when the observation region 111 is photographed. The graduated mesh around the ice crystal particles may serve to align with the ice crystal particles, thereby providing information about the size of the ice crystal particles. In the subsequent resolving process, the scale grid information and the ice crystal particle information in the optical image are compared, so that the size information of the ice crystal particles can be resolved simply and rapidly without complex size resolving process.
According to the embodiment, the floating equipment is set to be the transparent floating ball, the scale grid is arranged in the observation area of the transparent floating ball, the imaging equipment is used for shooting the observation area provided with the scale grid, the ice crystal particle image adsorbed on the observation area provided with the scale grid is collected, the weight of the detector can be reduced, and meanwhile, the scale information of the ice crystal particles can be rapidly obtained, and complex operation is not needed.
In the present embodiment, the optical image of the observation area with high resolution is only required to be collected to collect ice crystal particle information inside typhoons. The resolution of the optical image of the observation area depends on the resolution of the camera device, in the implementation, the camera device with high resolution is arranged to collect the ice crystal particle information with high quality, and the mode of collecting the ice crystal particle information has a simple hardware structure, is easy to realize, does not need to carry out excessive complex hardware design and software design, and is convenient for production and application.
In practice, the camera may be a microscopic camera with a resolution on the order of millimeters. Typhoon ice crystal particles are typically on the order of millimeters in size. By adopting the millimeter-level microscopic image pickup device, the quality and the cost of the acquired image can be considered, and the cost is reduced while the quality of the acquired image is ensured. Of course, the image pickup device can also adopt other microscopic image pickup devices with resolution above millimeter level so as to improve the image acquisition quality.
Further, the main body detecting portion may further include: and the control device can be arranged at the first end of the main body detection part, can be integrated with the imaging device in one device and is used for controlling the imaging device to shoot the observation area when the detector reaches the flat-floating state, so as to obtain an optical image of the observation area in the flat-floating state. In the flat floating state, the detector slowly floats, and the relative movement of ice crystal particles and floating balls is small. By shooting the observation area in the flat-floating state, the image of the ice crystal particles in the obtained optical image cannot be blurred, and the collection quality of typhoon ice crystal particle information can be further improved.
Embodiment III
As can be seen from the application scenario of the embodiment of the present invention shown in fig. 1, the stratospheric airship generally flies to the target delivery height of the stratosphere above typhoons, and the detector is delivered at the target delivery height. After being put in, the detector continuously falls under the action of self gravity, and finally, the detector achieves a flat-floating state.
The membrane balloon of the above embodiment is a non-inflatable balloon, the interior of which is pre-filled with a gas. Compared with inflatable balloons such as rubber floating balloons, the size of the film floating balloon is basically unchanged after inflation, so that the distance from an observation area on the film floating balloon to an imaging device is relatively fixed, the focal length of the imaging device is convenient to set, the focal point of the imaging device is arranged on the observation area, and a high-quality image of the observation area is shot.
However, the tensile strength of the film float ball is limited, and the target throwing height is usually higher in the stratosphere, the higher the height is, the lower the air pressure is, and the film float ball is likely to burst due to the excessively low air pressure at the target throwing height. In addition, typhoon weather information needs to be detected at a certain height, and the detector needs to be in a flat state at the height so as to collect typhoon weather information. If the setting of the film floating ball is unreasonable, the film floating ball cannot reach a flat floating state at the target flat floating height, so that ideal typhoon weather information cannot be acquired.
The present embodiment provides a typhoon information detector having a structure substantially similar to that of the first embodiment or the second embodiment. Further, on the basis of the probe provided in the first or second embodiment, the thin film floating ball in the probe provided in the first embodiment has a first specification, where the first specification is a specification that the thin film floating ball cannot burst at the target throwing height, and the probe reaches the flat-floating state at the target flat-floating height, and is determined comprehensively according to the target throwing height, the target flat-floating height, and the allowable differential pressure of the thin film floating ball.
Fig. 4 is a schematic diagram of a specification determining process of a film floating ball according to an embodiment of the present invention. As shown in fig. 4, the first specification may be determined by the following method.
S101: providing a plurality of film floating balls with different specifications.
Wherein, can provide a plurality of film floating balls of different specifications from nominal sphere diameter, film thickness two dimensions. In addition to the parameters of these two dimensions, the other parameters between different film floating balls are all the same.
In practice, a plurality of empirical values of nominal spherical diameter and a plurality of empirical values of film thickness may be determined, and a plurality of film floating balls of different specifications may be provided based on the plurality of empirical values of nominal spherical diameter and the plurality of empirical values of film thickness. For example, nominal spherical diameters of 2 meters, 1.8 meters, 1.5 meters, respectively, and film thicknesses of, respectively, 2 meters, 1.8 meters, 1.5 meters may be provided: a 0.025, 0.02 float ball, i.e. a film float ball of (nominal ball warp, film thickness) = (2,0.025), (1.8,0.025), (1.5,0.025), (2,0.02), (1.8,0.02), (1.5, 0.02) can be provided.
S102: and determining the allowable differential pressure of each film floating ball according to the nominal ball diameter and the film thickness of each film floating ball in the plurality of film floating balls.
In practice, the allowable differential pressure of a membrane float ball may be calculated by the following formula:
wherein,,
represents the allowable differential pressure, D represents the nominal sphere diameter, t represents the film thickness, + the thickness of the film>
Represents the tensile coefficient, which is a coefficient related to the material of the film.
S103: and determining a plurality of candidate floating balls from the plurality of film floating balls according to the target pressure difference between the target throwing height and the target flat floating height.
Wherein the candidate float ball is a membrane float ball that allows a differential pressure above the target differential pressure. The target pressure differential is the difference in atmospheric pressure between the target launch altitude and the target fly altitude. The target delivery height is the height of the stratosphere delivery detector, which is the highest height reached by the detector. The target level is the height at which the weather information needs to be collected.
In the implementation, the atmospheric pressure of the target throwing height and the atmospheric pressure of the target leveling height may be obtained, a difference between the two atmospheric pressures is used as a target differential pressure, and a film float ball having a permissible differential pressure equal to or higher than the target differential pressure is selected from the provided plurality of film float balls based on the target differential pressure and the permissible differential pressure of each of the plurality of film float balls, and the float balls are used as candidate float balls.
S104: and calculating the theoretical flat floating height of each candidate floating ball in the plurality of candidate floating balls.
The theoretical flat floating height of each candidate floating ball is the height when the detector reaches the flat floating state after each candidate floating ball is adopted. At this height, the buoyancy of the float ball and the overall weight of the sonde are balanced.
In practice, the theoretical fly height of each candidate flying ball may be calculated by:
calculating the weight of each candidate floating ball when the gas rushing into the candidate floating ball reaches the nominal ball diameter;
determining the weight of the detector corresponding to each candidate floating ball according to the weight of each candidate floating ball and the weight of other parts of the detector;
calculating the height when the buoyancy of the floating ball is balanced with the integral weight of the detector according to the integral weight of the detector corresponding to each candidate floating ball and the buoyancy of each candidate floating ball under the nominal spherical diameter;
this height was taken as the theoretical fly height for each candidate flying ball.
S105: determining a target float ball from the plurality of candidate float balls according to the target float height and the theoretical float heights of the candidate float balls;
the candidate float ball with the smallest absolute value of the difference between the theoretical fly height and the target fly height, i.e. the candidate float ball with the closest theoretical fly height to the target fly height, can be used as the target float ball.
S106: and taking the specification of the target floating ball as the first specification.
In some cases, there may be a plurality of target floating balls determined by the above method. In this case, the specification of the target floating ball having the smallest nominal ball diameter may be regarded as the first specification. Therefore, when carrying the stratospheric airship, the space can be saved as much as possible, and the stratospheric airship can carry more equipment conveniently.
According to the embodiment of the invention, the target throwing height of the stratospheric airship, the target flat-floating height of the detector and the allowable pressure difference of the film floating ball are fully considered, and the specification of the film floating ball is set to be a first specification, so that the film floating ball cannot burst at the target throwing height, and stable typhoon weather information can be conveniently collected when the target flat-floating height reaches a flat-floating state.
In this embodiment, assuming that the target altitude of the probe is the highest altitude of the stratospheric airship mounted on the probe, in other embodiments, the highest altitude of the stratospheric airship may be obtained, when the highest altitude of the stratospheric airship is used as the highest altitude of the probe, the specification of the thin film floating ball is determined according to the highest altitude of the stratospheric airship, the target altitude and the allowable differential pressure of the thin film floating ball, and the determination method of the specification may refer to the method for determining the specification of the thin film floating ball, and the target altitude in the method may be replaced by the highest altitude of the stratospheric airship, which is not repeated herein.

However, the present invention is not limited to this, and in one embodiment, the position information of the probe, the temperature information, the humidity information, and the air pressure information in the typhoon are acquired in addition to the ice crystal particle information in the typhoon, thereby providing a multi-weather information acquisition probe.
