Description

Technical Field

[0001] The present invention relates to the field of aerospace popular science demonstration devices, and in particular to a device for dynamically simulating and demonstrating the interstellar transfer of spacecraft. This device can vividly and intuitively display the orbit of the spacecraft's interstellar transfer (such as the transfer between the Earth and the Moon) and its orbital operation process. Background Art

[0002] In modern aerospace education and popular science activities, helping students and the public understand the principle of the orbital motion of spacecraft is an important goal. However, in current aerospace popular science education, the display of the orbital motion of spacecraft mostly stays at the stage of theoretical analysis and static models. Although these methods can reflect some situations of the orbital motion of spacecraft, it is difficult to intuitively display the dynamic changes of the spacecraft on the orbit, especially the key processes such as speed change, orbit transfer, and orbit adjustment.

[0003] The existing aerospace popular science equipment and demonstration methods have the following deficiencies: 1. Lack of dynamic display: Most of the existing demonstration devices can only display static models or simple animations of spacecraft, and cannot simulate the dynamic motion of the spacecraft on the orbit in real time.

[0004] 2. Lack of interactivity: Most of the existing demonstration devices do not have interactivity, and the audience cannot adjust the demonstration process by operating the device, thus affecting the demonstration effect.

[0005] 3. High complexity: Some of the existing demonstration devices have complex structures and cumbersome operations, and are not suitable for use in classroom education or popular science activities.

[0006] 4. Lack of intuitiveness: The existing demonstration devices are difficult to intuitively display the speed change and orbit adjustment process of the spacecraft in different orbital stages, and are difficult to help students and the public understand the complex orbital mechanics principle.

[0007] In addition, most of the existing aerospace popular science equipment focuses on the design and launch stages of spacecraft, and there is a lack of effective display means for the orbital motion process of spacecraft, especially the orbital motion process of transferring between the Earth and the Moon. The above deficiencies result in students and the public's understanding of the orbital motion of spacecraft staying at the abstract theoretical level and being difficult to form an intuitive understanding.

[0008] Therefore, there is a need for a device that can dynamically simulate and demonstrate the orbital motion process of the interstellar transfer of spacecraft (such as the transfer between the Earth and the Moon) to help students and the public better understand the principle of the orbital motion of spacecraft.

[0022] Compared with the prior art, the present invention has the following beneficial effects: (1) The device for dynamically simulating and demonstrating the interstellar transfer of a spacecraft provided by the present invention includes a first simulated planet, a second simulated planet, and a simulated orbit. The first simulated planet and the second simulated planet are respectively used to simulate two real planets. According to the real spatial positions, shapes, sizes, and the distance between the two simulated planets, the spatial positions, shapes, sizes, and the distance between the first simulated planet and the second simulated planet are set according to a preset reduction ratio.

The light strip is arranged on the simulated orbit and covers the entire simulated orbit. The light strip is electrically connected to the central control unit, and the central control unit can send a first control signal to the light strip. The first control signal is used to control the on / off, state change, light color, and light flashing speed of all the LED lights on the light strip. The position where the currently flashing LED light is located on the light strip represents the current position of the spacecraft running on the orbit. When the spacecraft moves forward to the position where the next LED light is located, the next LED light flashes, while the state of the previous LED light changes from flashing to constantly on. The light strip simulates the running speed of the spacecraft through the light flashing speed of its LED lights. The faster the light flashing speed of the light strip, the faster the running speed of the spacecraft; on the contrary, the slower the light flashing speed of the light strip, the slower the running speed of the spacecraft. Therefore, the device can dynamically display the running speed of the spacecraft and its speed change through the light flashing of the light strip.

The display screen is used to display the operation information of each stage of the simulated spacecraft running on the simulated orbit.

Each stage of the simulated spacecraft running on the simulated orbit includes a launch into orbit stage, an earth orbiting flight stage, a phasing orbit stage, an earth-moon transfer stage, a near-moon braking stage, a moon orbiting flight stage, and a landing and descent stage.

Description of the Drawings

[0027] The following further details the specific embodiments of the present invention with reference to the drawings. Figure 1 It is a schematic diagram of the simulated orbit of the device for dynamically simulating and demonstrating the interstellar transfer of a spacecraft provided by the embodiment of the present invention; Figure 2 It is a schematic diagram of the control relationship of the device for dynamically simulating and demonstrating the interstellar transfer of a spacecraft provided by the embodiment of the present invention; Figure 3 It is a schematic diagram of the central control unit of the device for dynamically simulating and demonstrating the interstellar transfer of a spacecraft provided by the embodiment of the present invention. Detailed Description of the Embodiment

[0028] To illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present invention.

[0029] As Figure 1 shown, this embodiment provides a device for dynamically simulating the interstellar transfer of a spacecraft, which includes a first simulated planet, a second simulated planet, a simulated orbit, a central control unit 10, and a light strip 20.

[0030] In a preferred implementation manner of this embodiment, the above device further includes a display screen 30.

[0031] The first simulated planet and the second simulated planet are respectively used to simulate two real planets. According to the real spatial positions, shapes, sizes of the two simulated planets and the distance between them, and set the spatial positions, shapes, sizes of the first simulated planet and the second simulated planet and the distance between them according to a preset reduction ratio. For example, the first simulated planet is used to simulate the real Earth, and the second simulated planet is used to simulate the real Moon. According to the real spatial positions, shapes, sizes of the Earth and the Moon and the distance between them, and set the spatial positions, shapes, sizes of the first simulated planet (i.e., the simulated Earth) and the second simulated planet (i.e., the simulated Moon) and the distance between them according to a preset reduction ratio (for example, the ratio is 1:100000000). In this embodiment, the first simulated planet and the second simulated planet are supported and fixed by a first support mechanism.

[0032] According to the orbital position, orbital shape and orbital parameters of a real spacecraft transferring between two real planets, and set the position and shape of the simulated orbit in three-dimensional space according to a preset reduction ratio; the simulated orbit is made of aluminum wire, so that the simulated orbit is easy to shape and does not affect the light display. For example, according to the orbital position, orbital shape and orbital parameters of a real spacecraft transferring between the Earth and the Moon, and set the position and shape of the simulated orbit in three-dimensional space according to a preset reduction ratio. In this embodiment, the simulated orbit is supported and fixed by a second support mechanism.

[0033] The light strip 20 includes a number of LED lights arranged at equal intervals (that is, the distance between any two adjacent LED lights is equal when the light strip 20 is arranged in a line), and each LED light on the light strip 20 can be in a flashing state or a constant-on state; each LED light on the light strip 20 can display different colors. The light strip 20 is arranged on the simulated orbit and covers the entire simulated orbit. In this embodiment, the light strip 20 adopts, for example, a WS2812B light strip.

[0034] The position of the currently flashing LED on the light strip represents the current position of the spacecraft in orbit. When the spacecraft moves forward to the position of the next LED, the next LED flashes, while the state of the previous LED changes from flashing to constant on. For example, at time t1, the spacecraft moves to point P1 on the simulated orbit, and the LED at point P1 flashes. At the next moment, i.e., time t2, the spacecraft moves to point P2 on the simulated orbit, and the LED at point P2 flashes. At this time, the state of the LED at point P1 changes from flashing to constant on. The light strip simulates the running speed of the spacecraft through the flashing speed of its LEDs. The faster the flashing speed of the light strip, the faster the spacecraft runs; conversely, the slower the flashing speed of the light strip, the slower the running speed of the spacecraft. For example, as Figure 1 shown, at the perigee point A, the flashing speed of the light strip is faster, indicating that the spacecraft runs faster here; at the apogee points B1 and B2, the flashing speed of the light strip is slower, indicating that the spacecraft runs slower here.

[0035] As Figure 2 shown, both the light strip 20 and the display screen 30 are electrically connected to the central control unit 10. The central control unit 10 can send a first control signal to the light strip 20. The first control signal is used to control the on / off, state change (such as changing from the flashing state to the constant on state), light color, and light flashing speed of all the LEDs on the light strip 20. The central control unit 10 can also send a second control signal to the display screen 30. The second control signal is used to control the on / off of the display screen 30 and its display content.

[0036] As Figure 3As shown, the central control unit 10 includes a single-chip microcomputer 11, a power supply module 12, and a storage module 13. The power supply module 12 and the storage module 13 are both electrically connected to the single-chip microcomputer 11. In this embodiment, for example, the single-chip microcomputer 11 uses an Arduino single-chip microcomputer, and Arduino Uno is selected as the control core. The WS2812B light strip 20 is connected to the Arduino single-chip microcomputer 11 through a general-purpose input / output port, that is, a GPIO (General Purpose Input Output) interface. The power supply module 12 uses a 9V DC power supply, and the power supply module 12 is built-in with a voltage stabilization circuit (not shown in the figure) to ensure that the power supply module 12 outputs a stable voltage. The power supply module 12 provides a stable 5V DC power for the single-chip microcomputer 11, and the power supply module 12 supplies power to all modules electrically connected to the central control unit 10 through the single-chip microcomputer 11, such as supplying power to the light strip 20, the display screen 30, the interaction module 40, and the sound module 50 respectively, to ensure the stable operation of the above-mentioned device. The storage module 13 uses an electrically erasable programmable read-only memory EEPROM (Electrically Erasable Programmable read only memory) to store the operation data and simulation parameters of the simulated spacecraft running on the simulated orbit. After the above-mentioned device is restarted, the storage module 13 can be restored to the initial settings.

[0037] In this embodiment, the single-chip microcomputer 11 of the central control unit 10 is loaded with an Arduino software program for controlling the light strip 20 and the display screen 30.

[0038] In this embodiment, the display screen 30 uses an OLED screen. The display screen 30 is driven by an SSD1309 driver. The display screen 30 is connected to the Arduino single-chip microcomputer 11 through a serial peripheral interface, that is, an SPI (Serial Peripheral Interface) interface. The display screen 30 is used to display the operation information of each stage of the simulated spacecraft running on the simulated orbit. The operation information of each stage includes the name of the current stage, the real-time running speed and position of the simulated spacecraft; each stage of the simulated spacecraft running on the simulated orbit includes the launch into orbit stage, the circumterrestrial flight stage, the phasing orbit stage, the earth-moon transfer stage, the near-moon braking stage, the circumlunar flight stage, and the landing and descent stage; the display screen 30 can dynamically update its display content, and the content displayed on the display screen 30 is synchronized with the running state of the simulated spacecraft on the simulated orbit.

[0039] It should be noted that the central control unit 10 can control the LED lights on the light strip 20 to display different colors. Specifically, the central control unit 10 can control the LED lights on the light strip 20 to display different colors according to the various stages of the simulated spacecraft running on the simulated orbit. For example, the LED lights corresponding to the launch and orbit insertion section on the light strip 20 are displayed in red, the LED lights corresponding to the circumterrestrial flight section on the light strip 20 are displayed in orange, the LED lights corresponding to the phasing orbit section on the light strip 20 are displayed in yellow, the LED lights corresponding to the Earth-Moon transfer section on the light strip 20 are displayed in green, the LED lights corresponding to the near-Moon braking section on the light strip 20 are displayed in blue, the LED lights corresponding to the circumlunar flight section on the light strip 20 are displayed in purple, and the LED lights corresponding to the landing and descent section on the light strip 20 are displayed in white.

[0040] In a preferred implementation manner of this embodiment, the above device further includes an interaction module 40. The interaction module 40 is electrically connected to the central control unit 10. The interaction module 40 can receive the speed adjustment instruction manually input by the user and forward it to the central control unit 10. The central control unit 10 sends a third control signal (the third control signal is a flashing speed control signal) to the light strip 20 in response to the speed adjustment instruction from the user. The light strip 20 adjusts the flashing speed of the LED lights on the light strip 20 in real time according to the third control signal from the central control unit 10. For example, at time t1, the flashing speed of the LED lights on the light strip 20 is slow, that is, the running speed of the simulated spacecraft on the simulated orbit is slow. At this time, the simulated spacecraft is in the circumterrestrial flight stage, and the simulated spacecraft orbits around the first simulated planet (such as the simulated Earth) along a circular orbit but cannot transfer to the second simulated planet (such as the simulated Moon); at the next moment, that is, at time t2, if the user inputs a first speed adjustment instruction to the interaction module 40, and the first speed adjustment instruction makes the flashing speed of the LED lights on the light strip 20 become faster, that is, the running speed of the simulated spacecraft on the simulated orbit becomes larger, then the simulated spacecraft enters the phasing stage, that is, the simulated spacecraft orbits around the first simulated planet (such as the simulated Earth) along an elliptical orbit but cannot transfer to the second simulated planet (such as the simulated Moon); at the next moment, that is, at time t3, if the user continues to input a second speed adjustment instruction to the interaction module 40, and the second speed adjustment instruction makes the flashing speed of the LED lights on the light strip 20 continue to become faster, that is, the running speed of the simulated spacecraft on the simulated orbit continues to become larger, then the simulated spacecraft enters the interplanetary transfer (such as Earth-Moon transfer) stage, that is, the simulated spacecraft runs away from the first simulated planet (such as the simulated Earth) towards the second simulated planet (such as the simulated Moon)... The rest of the stages of the simulated spacecraft running on the simulated orbit can be deduced by analogy and will not be elaborated here.

[0041] In a preferred implementation manner of this embodiment, the interaction module 40 includes a plurality of buttons (not shown in the figure) for the user to input speed adjustment instructions and an LCD display screen (not shown in the figure). The LCD display screen is used to display the current setting state of the interaction module 40 and the instructions input by the user.

[0042] In a preferred implementation manner of this embodiment, the above device further includes a sound module 50. The sound module 50 is electrically connected to the central control unit 10. The central control unit 10 can send a fourth control signal to the sound module 50. The fourth control signal is used to control the sound module 50 to play sounds matching the simulated operating state of the spacecraft. For example, the sound module 50 can play the following sounds to the user: "The spacecraft is currently operating on an orbit at XX altitude", "The current operating speed of the spacecraft is XX km / s", "The spacecraft is currently at the perigee (or apogee)", "The spacecraft has started to adjust its orbit", "The operating speed of the spacecraft has started to increase"...

[0043] This embodiment takes the interplanetary transfer of a spacecraft between the Earth and the Moon as an example to introduce the device for dynamically simulating the interplanetary transfer of a spacecraft. However, those skilled in the art can understand that when the spacecraft transfers between other planets except the Earth and the Moon, the above device can also be applicable.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
