[0026] See also Figure 1 , Figure 1is a schematic diagram of a satellite remote sensing experience system provided by an embodiment of the present invention. The satellite remote sensing experience system provided by the present invention comprises: a ball screen interactive display subsystem, a digital sand table display subsystem and a spaceship simulation subsystem; wherein the spaceship simulation subsystem is used to determine the scene ID to be switched to according to the user's selection, and the spaceship simulation subsystem switches to the scene selected by the user in response to the command of the process control subsystem; the ball screen interactive display subsystem and the digital sand table display subsystem respond to the command of the process control subsystem and can realize linkage display with the spaceship simulation subsystem;

[0027] The process control subsystem is respectively connected to the ball screen interactive display subsystem, the digital sand table display subsystem and the spacecraft simulation subsystem for communication. The process control subsystem is used to view the scene configuration information, generate commands for the process control subsystem that are linked to the ball screen interactive display subsystem and the digital sand table display subsystem according to the scene configuration information, and generate commands for the central control subsystem.

[0028] Specifically, the satellite remote sensing experience system provided in this embodiment can realize the linkage display of the ball screen interactive display subsystem, the digital sand table display subsystem and the spacecraft simulation subsystem when the user needs it;

[0029] The spherical screen interactive display subsystem realizes real-time and historical retrospective display on the spherical screen according to the input remote sensing images; displays satellites and constellations in combination with augmented reality devices according to the connected satellite operation data; and realizes constellation demonstration and satellite and constellation remote sensing process demonstration in combination with augmented reality devices according to the configuration data.

[0030] The digital sand table display subsystem can realize full-area viewing of the digital sand table based on remote sensing data and GIS data, and dynamically demonstrate remote sensing image processes and remote sensing image applications.

[0031] The spacecraft simulation subsystem simulates a spacecraft performing a remote sensing mission. Users can use the joystick to adjust the direction and field of view of the spacecraft's remote sensing payload, and allow users to manually take remote sensing photos of the earth to experience the remote sensing missions of satellites at different altitudes and speeds. It also supports space travel and remote sensing observations of other planets or celestial bodies.

[0032] Furthermore, the ball screen interactive display subsystem, the digital sand table display subsystem and the spaceship simulation subsystem realize linkage display through the process control subsystem and the scene management subsystem;

[0033] The process control subsystem is the central control core subsystem of all systems. It provides a unified calling interface for the interactive control of each display subsystem, which includes two parts: one is the control interface of the display scene, and the other is the control interface of the exhibition hall environment. At the same time, the process control subsystem also includes a satellite operation calculation simulation module, which will build a satellite operation demonstration model. By calling the satellite coordinate data of the comprehensive perception data management subsystem, it calculates the satellite's operation trajectory and realizes the simulation display of the satellite operation characteristics.

[0034] In an optional embodiment of the present invention, it also includes: a scene management subsystem, which is communicatively connected to the process control subsystem, and the scene management subsystem responds to the parameters of the scene ID to be switched to forwarded by the process control subsystem, and determines the scene configuration information based on the parameters of the scene ID to be switched to, so that the ball screen interactive display subsystem, the digital sand table display subsystem and the spaceship simulation subsystem can query the scene configuration information.

[0035] The scene management subsystem is used to store various scene parameter configurations of the ball screen interactive display subsystem, digital sand table display subsystem and spaceship simulation subsystem, parameter configurations for automatic scene switching, and preview functions for related configuration parameters; specifically including: scene configuration functions for the linkage of the ball screen interactive display subsystem and the digital sand table display subsystem, scene configuration functions for the linkage of the spaceship simulation subsystem and the ball screen interactive display subsystem and the digital sand table display subsystem; as well as configuration preview functions; in terms of interfaces, interfaces are provided for the process management subsystem, the ball screen interactive display subsystem, the digital sand table display subsystem and the spaceship simulation subsystem to obtain their respective configuration information.

[0036] It can be understood that the spaceship simulation subsystem determines the scene ID to be switched to according to the user's selection, and sends the parameters of the scene ID to be switched to to the process control subsystem. The process control subsystem matches the corresponding scene configuration information in the scene management subsystem according to the parameters of the scene ID to be switched to, and calls the corresponding process strategy according to the scene configuration information, generates a command for the process control subsystem, and the spherical screen interactive display subsystem and the digital sand table display subsystem respond to the command of the process control subsystem to determine whether to perform a linkage display with the spaceship simulation subsystem. In this way, the system architecture design for satellite flight status display is realized, and the linkage display of the spaceship simulation subsystem, the spherical screen interactive display subsystem and the digital sand table display subsystem is further realized, and the coupling degree between multiple subsystems is low, which is convenient for system expansion.

[0037] In an optional embodiment of the present invention, the scene configuration information includes scene attribute information, central control mode identification, satellite ID, satellite name and two-line root number; wherein the scene attribute information includes scene attribute ID, scene category ID, scene attribute name, scene attribute code, scene attribute keyword, creator, modifier, creation date and modification date.

[0039] In an optional embodiment of the present invention, see Figure 2 , Figure 1 is another schematic diagram of a satellite remote sensing experience system provided by an embodiment of the present invention, wherein the spacecraft simulation subsystem includes an operating lever, a dynamic seat, a remote sensing load simulation display screen, an instrument display screen, and a spacecraft simulation software;

[0040] If the joystick is operated, the spacecraft simulation software acquires the bias signal generated by the operation of the joystick and forwards it to the process control subsystem;

[0041] Calculate and set the deflection angle of the spacecraft remote sensing payload according to the bias signal; optionally, calculate and set the ground area displayed by the spacecraft simulation subsystem to simulate the deflection angle of the spacecraft remote sensing payload;

[0042] According to the bias signal, the dynamic seat offset angle is calculated and set; optionally, the dynamic seat offset angle is calculated by simulating the reaction force of the spacecraft receiving the deflection of the spacecraft telemetry load.

[0043] It should be noted that the operation of the operating lever can determine the swing angle of the spacecraft remote sensing payload and the deflection angle of the dynamic seat. In addition, the dynamic seat can also be reset, emergency stopped, adjusted forward and backward, etc. through physical buttons. Among them, the buttons on the dynamic seat are communicated with the central control subsystem.

[0044] It should be noted that the joystick is an operable handle in a spacecraft, and the joystick includes operations of multiple degrees of freedom.

[0045] In an optional embodiment of the present invention, the spacecraft simulation software simulates the field of view of the spacecraft remote sensing payload in response to the bias signal, and simulates the side swing and focusing of the spacecraft remote sensing payload.

[0046] In an optional embodiment of the present invention, when the spherical screen interactive display subsystem and the digital sandbox display subsystem are linked with the spacecraft simulation subsystem for display, the spherical screen interactive display subsystem and the digital sandbox display subsystem respond to the bias signal and simultaneously act on the content displayed by the spherical screen interactive display subsystem and the field of view of the digital sandbox display subsystem.

[0047] Furthermore, the viewing angle adjustment corresponding to the operation of the joystick includes swinging the joystick to the left (same to the right, forward, and backward) to rotate the main screen viewing angle of the spaceship to the left (same to the right, forward, and backward), and at the same time the dynamic seat deflects to the opposite direction; pressing the focus button (same to zooming in and zooming out) to achieve focusing; pressing the shooting button to achieve remote sensing of payload startup, and releasing the shooting button to shut down the payload; pressing the reset button to reset the main screen, seat, and focal length.

[0048] In an optional embodiment of the present invention, it further includes: an augmented reality support subsystem, which is communicatively connected to the process control subsystem;

[0049] When the spherical screen interactive display subsystem and the digital sandbox display subsystem respond to the command of the process control subsystem and realize linked display with the spacecraft simulation subsystem, the augmented reality support subsystem responds to the augmented reality close command in the command of the process control subsystem and closes the field of view displayed on the MR glasses.

[0050] Specifically, in this embodiment, the augmented reality support subsystem is a subsystem that cooperates with the spherical screen based on the augmented reality device to realize the display of the operation and remote sensing process of satellites and constellations. In conjunction with the spherical screen, the constellation demonstration and remote sensing process demonstration are carried out. The augmented reality device is used to construct a satellite orbit line and a three-dimensional model of the satellite in proportion to the spherical screen on the periphery of the spherical screen, and the spherical screen is operated in coordination with the display content of the spherical screen, so that the user can intuitively experience the demonstration of the constellation operation and remote sensing process.

[0051] Optionally, the augmented reality support subsystem is a system set on the MR glasses. After the subsystem is turned on, it will automatically subscribe to the content of the MQTT Broker. The process control subsystem does not need to care whether anyone has subscribed, and can just blindly send a close command. It can also be understood that the augmented reality support subsystem recognizes that the process control subsystem command generated by the process control subsystem includes an identification of the linkage mode, and the augmented reality support subsystem responds to the augmented reality close command in the process control subsystem command, and closes the field of view displayed on the MR glasses to switch the field of view to the linkage display.

[0052] In an optional embodiment of the present invention, it also includes: an integrated perception subsystem, which is communicatively connected with the spherical screen interactive display subsystem, the digital sand table display subsystem and the spaceship simulation subsystem respectively; the spherical screen interactive display subsystem, the digital sand table display subsystem and the spaceship simulation subsystem obtain earth images from the integrated perception subsystem according to needs.

[0053] Specifically, in this embodiment, the comprehensive perception subsystem is the data center of the entire system. It is responsible for the management, publication and storage of various types of data in the system, such as remote sensing data at various time points, hierarchically cached image stitching data, geographic information vector data, system scene configuration data, etc. At the same time, it is also responsible for the access and processing of external data of satellites and constellation operation and control systems.

[0054] In an optional embodiment of the present invention, the spacecraft simulation subsystem is used to simulate the earth's surface observed by the user in the satellite, the spherical screen interactive display subsystem is used to provide a spherical screen to display the relevant interface of the earth, as well as the orbit and sub-satellite position of the current satellite, and the digital sand table display subsystem is used to display the field of view details of the spacecraft remote sensing payload observation in the form of a sand table.

[0055] In an optional embodiment of the present invention, the dome screen interactive display subsystem, the digital sandbox display subsystem and the spaceship simulation subsystem are linked to each other through the following process, specifically:

[0056] The user selects the satellite and scenario to be simulated on the control panel of the spacecraft simulation subsystem.

[0057] The control panel of the spaceship simulation subsystem obtains the scene ID to be switched to through the user's selection.

[0058] The control panel of the spacecraft simulation subsystem sends the parameters of the scene ID to be switched to the process control subsystem, which is then forwarded to the scene management subsystem by the process control subsystem.

[0059] The scene management subsystem determines the scene configuration information based on the parameters of the scene ID to be switched to. The scene configuration information includes scene attribute information (scene attribute ID, scene category ID, scene attribute name, scene attribute code, scene attribute keyword, creator, modifier, creation date, modification date, etc.), central control mode identification, satellite ID, satellite name, and two-line root number).

[0060] The process control subsystem retrieves the corresponding process strategy according to the scene configuration information and generates commands for the corresponding process control subsystem. The commands include: sending an augmented reality shutdown command, sending a state switching command to the central control subsystem (including light, power, audio and other state switching commands), and sending a scene switching command to the capsule workstation (including switching to simulated flight state, obtaining and playing satellite status information, and subscribing to operation commands); if the scene also requires the ball screen interactive display subsystem and the digital sand table display subsystem to display in linkage, then send state switching commands to the ball screen interactive display subsystem and the digital sand table display subsystem respectively, and the state switching commands include switching to linkage mode commands, subscribing to satellite status information and operation information commands, and refreshing satellite orbit information and status information commands; if the scene has augmented reality special effects, it is also necessary to send a state switching command to the augmented reality subsystem; the state switching commands include switching to linkage mode commands, subscribing to satellite status information and operation information commands, and refreshing satellite orbit information and status information commands.

[0061] The central control subsystem responds to the state switching command in the command of the process control subsystem to switch the state of each device, including switching the state of the light in the scene configuration, switching the state of the power supply in the scene configuration, and switching the state of the audio in the scene configuration.

[0062] The integrated perception subsystem is used to obtain and process data from satellites. The spacecraft workstation, ball screen interactive display subsystem, digital sand table display subsystem and spacecraft simulation subsystem all obtain relevant status information and data of satellites from the integrated perception subsystem.

[0063] If the user operates the joystick, such as changing the direction or pressing a button, etc., the bias signal generated by the operation of the joystick is obtained and forwarded to the process control subsystem.

[0064] Calculating and setting a deflection angle of a spacecraft telemetry payload according to the bias signal;

[0065] The dynamic seat offset angle is calculated and set according to the bias signal.

[0066] The process control subsystem forwards the above commands to scene-related devices, including: sending control commands for zooming the field of view to the ball screen interactive display subsystem and the digital sand table display subsystem according to the focus control command, and sending control commands for switching the field of view to the ball screen interactive display subsystem and the digital sand table display subsystem according to the bias signal.
