Description

[0001] This application claims the priority of a Chinese patent filed with the Chinese Patent Office on December 29, 2023, with application number 202311871856.1 and application name “A latex balloon height control method and latex balloon”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the field of balloon technology, and in particular to a latex balloon height control method and a latex balloon. Background Art

[0003] In recent years, with the continuous development and utilization of near-space resources, latex balloons have great development potential in various aspects such as regional disaster prevention, environmental monitoring, and regional communications due to their low price and portability. Latex balloons generally use natural rubber as the main material and add various additives to make the balloon skin. They are filled with hydrogen or helium with a density less than that of air to gain buoyancy and rise. After the balloon is released and reaches near-space, atmospheric environmental factors and space environmental factors (such as: atmospheric density, wind direction, wind speed, temperature, humidity, electric field strength, electron density, ion density, etc.) will affect the flight of the balloon. In order to achieve greater application value using latex balloons, it is necessary to achieve high controllability of latex balloons. Since latex balloons have excellent stretchability and are difficult to store pressure inside, the prior art generally estimates the amount of air to be inflated based on the target flight altitude of the floating balloon before release, and then carries the floating balloon into the air via another carrying balloon. This is because during the ascent, the balloon is greatly affected by external environmental factors such as unstable airflow in the sky, extremely variable ambient temperature (up to -80°C at high altitude), and solar radiation, and these influencing factors change all the time and cannot be calculated or predicted. The prior art has the problem of being unable to accurately control the floating balloon to fly at a set altitude, and also unable to actively control the altitude of the latex balloon during the high-altitude flight stage.

[0021] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0022] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be understood by people with ordinary skills in the field to which this disclosure belongs.

[0023] To facilitate understanding of the latex balloon height control method provided in the embodiment of the present application, its application scenario is first described. The latex balloon height control method provided in the embodiment of the present application is used to control the leveling effect of the leveling balloon. After rising to the leveling height, the current latex balloons are often unable to achieve precise leveling flight, because the balloon is greatly affected by the external environment during the ascent, with the temperature as low as -80°C. In addition, solar radiation also has an impact, and such impacts change all the time and cannot be calculated or predicted. For this reason, the embodiment of the present application provides a latex balloon height control method to improve the control effect of the leveling balloon during leveling. The following is a detailed description of it in conjunction with specific drawings and embodiments.

[0024] It is difficult to achieve high controllability of latex balloon aircraft, that is, to control the rise and fall of the balloon, because due to the weight and battery energy limitations of latex balloons, it is impossible to use fans to pump and deflate air at high altitudes like airships and plastic balls. At present, the development technology of deflation devices for latex balloons is not mature. Due to the excellent expansion performance of latex balloons, it is difficult to accumulate pressure inside the ball, and the pressure difference between the inside and outside is small. The technology of relying on pressure sensor sensing to achieve deflation is difficult to apply directly, and the quantitative and timing judgment of ejection is also relatively complicated. In addition, the latex balloon carries a small load mass, and the lightweight technology of the device is also a difficulty in design and production. At the same time, the device must also take into account multiple functions such as safe descent and no conflict with the route.

[0025] To this end, the embodiment of the present application provides a control method for a latex balloon, which realizes the rise and fall control of the balloon by means of jettisoning the capsule and deflation of the valve, respectively, so as to realize the adaptive control of the height of the latex balloon aerostat at high altitude. The height control method for the latex balloon provided by the embodiment of the present application is described in detail below.

[0026] refer to Figure 1 As shown, Figure 1 A flow chart of a latex balloon height control method provided in an embodiment of the present application is shown.

[0027] The latex balloon height control method comprises the following steps: Step 001: Obtain the altitude information of the flat-floating balloon; Specifically, when obtaining the altitude information of the floating balloon, it can be obtained through the positioning module on the floating balloon, and the positioning module can be a passive / GPS positioning module. When in use, the acquired altitude information can be transmitted to the chip of the floating balloon through the positioning module to obtain the altitude information of the floating balloon. In the embodiment of the present application, the altitude information can also include the latitude and longitude information of the floating balloon to obtain the accurate position of the floating balloon.

[0028] Step 002: obtaining the ascending speed status information of the flat-floating balloon according to the altitude information of the flat-floating balloon; Specifically, the speed state information of the floating balloon can be determined by the height information provided by the positioning module. For example, at t1, the height of the floating balloon is obtained as H1; at t2, the height of the floating balloon is obtained as H2, and the speed information of the floating balloon can be calculated according to the speed calculation formula and t1, t2, H1 and H2.

[0029] Step 003: determining the lifting and lowering state of the flat-floating balloon according to the lifting speed state information of the flat-floating balloon; Specifically, it can be determined whether the vehicle is in an ascending or descending state based on the ascending speed state information of the vehicle.

[0030] Step 004: according to the ascending and descending state of the flat-floating balloon, the ascending speed information of the flat-floating balloon and the set deflation or ejection strategy, the flat-floating balloon is deflated or ejected until the height of the flat-floating balloon is within the set height range.

[0031] Specifically, during control, different state control methods such as rising and falling are included, which are explained one by one below.

[0032] When the flat-floating balloon is in an ascending state, it is necessary to deflate the balloon. The strategy to be implemented during deflation is as follows: Step a: when the flat-floating balloon is deflated, when the rising speed of the flat-floating balloon is within a first set rising speed range, controlling the deflation time of the flat-floating balloon to reach 1 / 3 of the set time; Step b: when the rising speed of the flat-floating balloon is within the second set rising speed range, controlling the deflation time of the flat-floating balloon to reach 2 / 3 of the set time; Step c: when the rising speed of the flat-floating balloon is within a third set rising speed range, controlling the deflation time of the flat-floating balloon to reach a set time; The first set speed increase range is smaller than the second set speed increase range, and the second set speed increase range is smaller than the third set speed increase range.

[0033] When the floating balloon is in the descending state, it is necessary to jettison the balloon. The strategy implemented during jettisoning is as follows: When jettisoning the flat-floating balloon, the jettisoning is performed according to the jettisoning setting time controlled by the switch; The density of the jettisoned ballast and the weight of the equipment carried by the buoyant balloon satisfy the following requirements: The heavier the equipment a buoyant balloon carries, the greater the density of the ballast.

[0034] In the specific processing process, the control method uses the means of ejection and deflation to achieve the rise and fall control of the latex balloon. The ejection and deflation are performed through the preset program on the chip built into the flat-floating balloon. The specific process is to transmit the information of the Beidou / GPS positioning module to the chip (the specific information includes the altitude + longitude and latitude information), and judge whether the altitude, ascent speed and other conditions of the balloon system at this time meet the preset target altitude and ascent speed through the preset program, and control according to the above-set strategy. Exemplarily, when the ascent speed is relatively small, if the deviation between the ascent speed and the theoretical ascent speed is within ±0.5m, it is determined that the ascent speed meets the preset target, then the device system does not work and continues to monitor. If the deviation between the ascent speed and the theoretical ascent speed is within 0.5m~1m, it is considered that the ascent speed is too fast, and the deflation time will reach 1 / 3 of the set time. If the deviation between the ascent speed and the theoretical ascent speed is within 1m~1.5m, it is considered that the ascent speed is too fast, and the deflation time will reach 2 / 3 of the set time. If the deviation between the speed increase and the theoretical speed increase is greater than 1.5m, the speed increase is considered too fast and the deflation time is set to the set time. The speed increase unit is meters per second.

[0035] If the balloon is judged to be too low or continuously falling, the system will activate the jettison device to discard the load. When inflating, the inflation volume of the balloon is determined according to the weight of the equipment carried by the balloon. The inflation volume of the balloon and the weight of the equipment satisfy the following relationship: the heavier the equipment, the greater the inflation volume of the balloon.

[0036] The strategy of jettisoning is as follows: The ballast in the cabin is discharged through switch control. When jettisoning, the duration of the switch is certain, and the amount of gas is related to the density of the ballast. For example, if the amount of gas is low (the weight of the equipment carried is low), the density of the ballast is low, and the weight thrown is relatively low. Due to the small amount of gas, there will also be a significant speed impact. If the amount of gas is large (the weight of the equipment carried is large), the density of the ballast is large, and the weight thrown is large), the floating balloon will rise. On the contrary, if the floating balloon is too high or continues to rise, the system will start the deflation device to release the buoyancy gas inside the balloon to make the balloon system descend. Information such as the system height and position is sent out through the antenna and received on the ground.

[0037] The specific control strategy is as follows: according to the altitude data given by the positioning module, the real-time state of the balloon system's ascent speed is calculated. After reaching the predetermined flight leveling altitude (the boundary altitude of the region can be set, for example, 20,000 meters ± 500 meters; the carrying ball must be separated from the leveling balloon at 20,000 kilometers), the program monitors whether the accumulated ascent speed of the leveling system exceeds a preset value (0-999m) within the set detection time range (0-999s). If the altitude difference does not exceed the set value within the time range, the monitoring is repeated in a cycle. If the altitude difference is greater than the set value and is in an ascending state (accumulated as a positive value), the program controls the deflation switch to open, and the deflation time can be set to 0-999s; if the altitude difference is greater than the set value and is in a descending state, the program controls the jettison switch to open, and the jettison time is fixed each time. The jettison weight is controlled by adjusting the mass density of the ballast. After the deflation or jettisoning action is completed, a detection delay (0-999s) is performed before entering the monitoring state.

[0038] In addition, the device only performs deflation operations at the upper boundary of the set area, and only performs capsule jettisoning operations at the lower boundary of the set area. If it exceeds the upper / lower boundary, it will deflate / jet the capsule after each detection delay (if deflated, it will be deflated for a complete cycle;) until the system altitude returns to the set flight area.

[0039] It should be understood that in the above scheme, the control of deflation or ejection of the floating balloon 200 is performed when the floating balloon 200 is in a floating state. Figure 3 As shown, the latex balloon includes a floating balloon 200 and a carrying ball 100, the floating balloon 200 and the carrying ball 100 are connected through a fuse 300, and the floating balloon 200 is lifted into the air by the carrying ball 100 to enter the floating area. When the two are separated, the connecting rope connecting the carrying ball 100 and the floating balloon 200 is directly melted and separated by the fuse 300 (heating resistance wire); wherein, the carrying ball 100 continues to rise, while the floating balloon 200 flies horizontally within the set altitude range.

[0040] When deflation or jettisoning is performed, after the carrying ball 100 is separated from the floating balloon 200 for a set time, the floating balloon 200 is deflated or jettisoned according to the ascending state of the floating balloon 200, the ascending speed information of the floating balloon 200, and the set deflation or jettisoning strategy, until the ascending speed of the floating balloon 200 is within the set ascending speed range. That is, after the floating balloon 200 is separated from the carrying ball 100 for a certain time, the floating balloon 200 is controlled, thereby offsetting the influence of the ascending speed of the floating balloon 200 led by the carrying ball 100 on the judgment of the floating balloon 200.

[0041] In an optional solution, the moment when the carrying ball 100 is separated from the floating balloon 200 satisfies: when the height information of the floating balloon 200 exceeds the center value of the set height range, the carrying ball 100 is controlled to separate from the floating balloon 200. The above-mentioned height range refers to a height range set for the floating balloon 200, and the middle information of the height range is the center value of its height range. Exemplarily, the highest height is G1, the lowest height is G2, and the center value G=G2+(G1-G2) / 2. When the two are separated, they are controlled by the fuse 300. The fuse 300 includes a signal receiver, a heating resistor, a rope, a battery, and a heat preservation foam package. After reaching the center value of the set height range, a short-range communication instruction of a fuse is sent to the fuse 300 through the control chip. The fuse 300 will start the fuse rope to realize the separation of the carrying ball 100 and the floating balloon 200, and the fuse 300 will rise together with the carrying ball 100 to avoid affecting the horizontal flight of the floating balloon 200.

[0042] When executing the deflation and ejection strategy of the flat-drift balloon 200, the following steps are also specifically included: Step 1: When the altitude information of the flat-floating balloon 200 is higher than the maximum ceiling value of the set altitude range, the flat-floating balloon 200 is deflated according to the set time until the altitude information of the flat-floating balloon 200 is lower than the maximum ceiling value of the set altitude range.

[0043] Step 2: When the altitude information of the level-drifting balloon 200 is lower than the minimum ceiling value of the set altitude range, the capsule is jettisoned according to the jettisoning setting time until the altitude information of the level-drifting balloon 200 is higher than the minimum ceiling value of the set altitude range.

[0044] In the above technical scheme, by obtaining the altitude information of the flat-floating balloon, and obtaining the ascent speed information and the ascending and descending status of the flat-floating balloon through the altitude information, and deflation or ejection of the flat-floating balloon according to the set deflation or ejection strategy, the flat-floating balloon can be controlled to drift within the set range, thereby ensuring the stability of the flat-floating balloon during drifting and improving the effect of controlling the drifting of the flat-floating balloon.

[0045] like Figure 2 As shown, the embodiment of the present application further provides a latex balloon, which includes a flat-floating balloon 10, and a positioning module 20 disposed on the flat-floating balloon 10 and used to obtain height information of the flat-floating balloon 10; It also includes a control chip 30, which obtains the ascent speed status information of the flat-drifting balloon 10 according to the altitude information of the flat-drifting balloon 10; determines the ascending and descending state of the flat-drifting balloon 10 according to the ascent speed status information of the flat-drifting balloon 10; and deflates or jettisons the flat-drifting balloon 10 according to the ascending and descending state of the flat-drifting balloon 10, the ascent speed information of the flat-drifting balloon 10 and the set deflation or jettisoning strategy until the ascending speed of the flat-drifting balloon 10 is within the set ascending speed range.

[0046] In the above technical scheme, by acquiring the altitude information of the floating balloon 10, and acquiring the ascent speed information and the ascending and descending status of the floating balloon 10 through the altitude information, and deflation or ejection of the floating balloon 10 according to the set deflation or ejection strategy, the floating balloon 10 can be controlled to drift within the set range, thereby ensuring the stability of the floating balloon 10 when drifting, and improving the floating control effect of the floating balloon 10.

[0047] In a specific feasible implementation scheme, the control chip 30 is also used for controlling the deflation time of the flat-floating balloon 10 to reach 1 / 3 of the set time when the rising speed of the flat-floating balloon 10 is within a first set rising speed range; controlling the deflation time of the flat-floating balloon 10 to reach 2 / 3 of the set time when the rising speed of the flat-floating balloon 10 is within a second set rising speed range; and controlling the deflation time of the flat-floating balloon 10 to reach the set time when the rising speed of the flat-floating balloon 10 is within a third set rising speed range; wherein the first set rising speed range is smaller than the second set rising speed range, and the second set rising speed range is smaller than the third set rising speed range.

[0048] In a specific possible implementation scheme, the control chip 30 is also used to jettison the ballast 10 by jettisoning the ballast for a set time controlled by a switch; wherein the density of the ballast jettisoned and the weight of the equipment carried by the ballast 10 satisfy the following conditions: The greater the weight of the equipment carried by the buoyant balloon 10, the greater the density of the ballast.

[0049] In a specific feasible implementation scheme, the control chip 30 is also used to deflate the flat-floating balloon 10 according to a set time period when the altitude information of the flat-floating balloon 10 is higher than the maximum ceiling value of the set altitude range, until the altitude information of the flat-floating balloon 10 is lower than the maximum ceiling value of the set altitude range.

[0050] The specific control method of the above control chip can be referred to Figure 1 The specific process in the method steps will not be repeated in detail here.
