Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerospace model demonstration and simulation technology, and more specifically to a device for demonstrating the operation of Beidou satellites. Background Technology
[0002] The BeiDou Navigation Satellite System (BDS, also known as COMPASS) is a global satellite navigation system independently developed by China. It is the third mature satellite navigation system after GPS and GLONASS.
[0003] Unlike other satellite navigation systems, the BeiDou Navigation Satellite System adopts a unique "hybrid constellation of three orbits," including geostationary orbit (GEO), inclined geosynchronous orbit (IGSO), and medium Earth orbit (MEO) satellites, providing wider coverage.
[0004] To more conveniently and intuitively demonstrate the satellite operation principles of the BeiDou Navigation Satellite System, various static display models have been developed. However, when explaining the satellite operation principles, it is often necessary to use imagination or combine text, images, and video animations for explanation, which makes it difficult for the public to intuitively understand the structure of the BeiDou satellite operation system and the trajectory of BeiDou satellites.
[0005] Therefore, how to intuitively display the operational trajectories of BeiDou satellites in different orbits is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] In view of this, the present invention provides a device for demonstrating the operation of BeiDou satellites, which is used to intuitively and vividly display the orbital trajectories of BeiDou satellites in different orbits.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A device for demonstrating the operation of BeiDou satellites includes:
[0009] The Earth model and the satellite orbit assembly set around the Earth model are both fixed to the chassis by support rods. The satellite orbit assembly includes several independently set orbits. Each orbit is a closed ring structure and is provided with an orbital groove that is consistent with the orbital path. An orbital rack is installed in the orbital groove.
[0010] The satellite model includes a gear meshing with a track rack, a motor connected to and driving the gear to rotate, a battery power supply for the motor, and a motor drive module connected to the battery power supply and the motor. The motor drive module includes a wireless signal receiving module, a control chip connected to the output of the wireless signal receiving module, and a motor drive circuit module connected to the output of the control chip. The satellite model is secured to both sides of the track by a snap-fit structure and can move along the track groove under the rotation of the gear.
[0011] The control panel is equipped with a motor start / stop button and a wireless signal transmitting module connected to the motor start / stop button. The wireless signal transmitting module is wirelessly connected to the wireless signal receiving module of the satellite model.
[0012] Furthermore, the satellite orbit assembly includes several independently configured orbits: three medium Earth orbits, one geostationary orbit, and three inclined geosynchronous orbits.
[0013] Furthermore, each track in the satellite orbit assembly is fixed to the chassis by at least two support rods.
[0014] Furthermore, each track in the satellite orbit assembly is provided with a sliding groove on both sides, and the path of the sliding groove is consistent with the path of the track groove, so that the snap-fit structure of the satellite model can snap into the sliding groove and slide within the sliding groove.
[0015] Furthermore, the sliding groove is located in the middle of the track sidewall, and the groove width is less than or equal to one-tenth of the track sidewall width.
[0016] Furthermore, the control chip is an STM32F407VET6 chip.
[0017] Furthermore, both the wireless signal receiving module and the wireless signal transmitting module use the NRF24L01 monolithic radio frequency transceiver chip.
[0018] Furthermore, the satellite models in different orbits are painted with different colors of paint.
[0019] Furthermore, LED light strips are installed along both sides of each track. The LED light strips installed on different types of tracks use LED light strips with different lighting colors. The control chip of the LED light strips is connected to the operating console through a wireless transmission module.
[0020] Furthermore, the satellite model is also equipped with LED lights. The lighting color of the LED lights on each satellite model is the same as the lighting color of the LED light strip on the corresponding orbit. The control chip of the LED lights is connected to the control panel through a wireless transmission module.
[0021] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a device for demonstrating the operation of Beidou satellites, which has the following beneficial effects:
[0022] Compared with existing static display models, this application enables satellite models to continuously cycle on their respective orbits through independently set orbits and corresponding satellite model driving structures, thus providing a more intuitive display of the operational trajectories of BeiDou satellites in different orbits.
[0023] This application uses a wireless communication module to control the start and stop of the satellite model, making the control of the satellite model more convenient and faster.
[0024] This application enables the public to intuitively distinguish the movement trajectories of satellites in different orbits by setting LED light strips of different colors on different types of orbits and using satellite models painted in different colors. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] like Figures 1-5 As shown in the figure, this utility model embodiment discloses a device for demonstrating the operation of Beidou satellites, comprising:
[0038] Earth model 1 and satellite orbit assembly 2 set around the Earth model are both fixed to the chassis 4 by support rod 3. Satellite orbit assembly 2 consists of multiple closed ring orbits 200 that surround the Earth model and are independent of each other. Each orbit 200 is provided with an orbital groove 201 that is consistent with the orbital path. An orbital rack 202 is installed in the orbital groove 201.
[0039] In this new design, each orbit is set independently, meaning there is no physical intersection between any two orbits. This allows satellite models on any orbit to continuously cycle along their respective orbits. Specifically, each orbit has a different height (distance) from the Earth model, and the closest spatial distance between two adjacent orbits is greater than the height of the satellite model.
[0040] Satellite model 5 includes a gear 501 meshing with the track rack 202, a motor 502 connected to the gear and driving the gear 501 to rotate, a battery power supply 503 supplying power to the motor, and a motor drive module 504 connected to the motor 502 and the battery power supply circuit; the motor drive module 504 includes an internally configured wireless signal receiving module, a main control chip, and a motor drive circuit module; the satellite model is secured to both sides of the track by a snap-fit structure 505 and can move continuously along the track under the rotation of the gear;
[0041] The control panel 6 is equipped with a motor start / stop button and a wireless signal transmitting module connected to the motor start / stop button (the wireless signal transmitting module is located inside the control panel and is not shown in the figure). The wireless signal transmitting module is wirelessly connected to the wireless signal receiving module of the satellite model. In this embodiment, the motor start / stop button includes a motor start button 601 and a motor stop button 602, which are used to control the rotation and stop of the motor, and thus control the start and stop of the satellite model's operation.
[0042] In this embodiment, the satellite orbit assembly includes three medium Earth orbits, one geostationary orbit, and three inclined geosynchronous orbits.
[0043] To differentiate between different orbits, this application sets up three control consoles to achieve motion control of satellite models on different types of orbits.
[0044] like Figure 7 As shown, for geostationary orbit, the control panel 6 is equipped with a motor start button 601 and a motor stop button 602. Pressing the motor start button 601 generates a command signal and transmits it to the wireless signal transmitting module inside the control panel. The wireless signal module transmits the signal to the wireless signal receiving module of the corresponding satellite model in geostationary orbit. The wireless signal receiving module decodes the received signal and inputs it to the input terminal of the control chip. The output terminal of the control chip outputs a motor start level signal to the motor drive circuit module. The motor drive circuit module is connected to the power supply and the motor. Driven by the motor start level signal, the motor drive circuit module turns on the power supply of the motor, causing the motor to rotate, thereby driving the rotation of the gear at the output terminal of the motor. Since the satellite gear meshes with the track rack 202 of the orbit, the continuous cyclic movement of the satellite model in the orbit is realized.
[0045] Motor start / stop button 602, other operation buttons 603 are used for one-button control of LED light strip on / off, 604 is used to control LED light on / off, and 605 is the main control switch.
[0046] In this invention, the control chip functions by outputting high and low levels to the motor drive circuit based on the electrical signals received by the wireless signal receiving module, thereby controlling the rotation and stopping of the motor. In practical applications, the control chip is an STM32F407VET6 chip. Both the wireless signal receiving module and the wireless signal transmitting module can use the existing NRF24L01 monolithic RF transceiver chip, and the motor drive circuit uses an L298N drive circuit. In a specific embodiment, the specific circuit connections of the STM32F407VET6 control chip, the wireless signal receiving module based on the NRF24L01 monolithic RF transceiver chip, and the L298N motor drive circuit of the satellite model are as follows: Figure 8 , Figure 9 , Figure 10As shown.
[0047] In addition, a semi-enclosed electronic display screen 7 is set up on the outside of the demonstration device. The electronic display screen 7 is used to statically display the relevant principles of the operation of Beidou satellites or play video animations to explain them. It plays an auxiliary role in the demonstration while the satellite model is actually moving.
[0048] In this embodiment, each track 200 in the satellite track assembly is provided with a sliding groove 203 on both sides. The path of the sliding groove 203 is consistent with the path of the track groove 201, so that the snap-fit structure 505 of the satellite model can be snapped into the sliding groove and slide within the sliding groove.
[0049] Each track 200 in the satellite track assembly is fixed to the chassis by at least two support rods 3. The upper end of the support rod is fixed to the track. The fixed end of the support rod 3 and the track 200 avoids the sliding groove 203 on the side of the track and is away from the side of the satellite model 5, so that the satellite model is not disturbed by the support rods 3 during the cyclic movement.
[0050] To facilitate the fixing of the support rod and ensure relative stability, the sliding groove 203 is set in the middle of the track side wall, and the groove width is less than or equal to one-tenth of the track side wall width.
[0051] like Figure 6 As shown, to distinguish the movement of satellites in different types of orbits, the surface of the satellite model is painted with different colors for each type of orbit. Furthermore, LED light strips 204 are installed along both sides of each track. The LED light strips on different types of tracks use LED light strips with different lighting colors. The control chip of the LED light strip is connected to the control panel 6 via a wireless transmission module (both the control chip and the connected wireless transmission module are located on the LED light strip, not shown in the diagram). The control panel 6 is equipped with control buttons to turn the LED light strips on and off for different tracks. Activating the control button sends an on / off signal to the wireless transmission module of the LED light strip via the corresponding wireless transmission module. Based on the signal received by the wireless transmission module, the power supply to the LED light strip is turned on, thereby controlling the LED light strip's on / off state.
[0052] Furthermore, each satellite model 5 is equipped with LED lights 506. The lighting color of each satellite model's LED light 506 is the same as the lighting color of the corresponding LED light strip on the track. The control chip of the LED light is connected to the control panel 6 via a wireless transmission module. The control panel 6 is equipped with control buttons to control the on / off state of the LED lights on different satellite models. After the control button is activated, the on / off signal is sent to the wireless transmission module of the LED light via the corresponding wireless transmission module. Based on the signal received by the wireless transmission module, the power supply of the LED light is turned on, thereby controlling the on / off state of the LED light.
