[0030] In this embodiment, the vehicle-mounted carrier 1 is a modified 12-meter-class large bus. The body is reinforced with lightweight steel, and the interior is divided into a central interactive area 3, a modular display area 4, and an equipment storage area 5 by environmentally friendly sound-insulating and heat-insulating panels. The central interactive area 3 is equipped with a circular display platform and audience rest seats. The modular display area 4 is distributed along both sides of the vehicle body, and the equipment storage area 5 is located at the rear of the vehicle-mounted carrier 1 for storing spare equipment and consumables.

Key parts of the models (such as the rocket engine and the space station's solar panels) are made of transparent material, and LED lights are installed inside to display the structure. The VR simulation experience unit uses the Pico 4VR headset, equipped with two science popularization software programs, "Spacewalk" and "Aircraft Piloting," to achieve an immersive experience in conjunction with the simulation control panel. The aerospace technology principle demonstration device simulates a rocket launch driven by compressed air. During the launch, sensors collect speed data, and light trajectories simulate a satellite orbiting the Earth, demonstrating the relationship between gravity and orbital motion. The intelligent control system uses a Siemens S7-1200 PLC as the main controller 12. The sensor group includes temperature, humidity, equipment status sensors and dedicated sensors for each module.

The human-machine interface terminal 13 includes three 15-inch touch screens (corresponding to basic operation, module control and data query respectively) and a voice interaction device (supporting Mandarin voice commands). The main controller 12 communicates with each module through the PROFINET bus to realize real-time monitoring and centralized control of the operating status of each module. For example, when the temperature of the 3D printing equipment is too high, the main controller automatically starts the fan of the ventilation and heat dissipation system 15 to accelerate heat dissipation and displays the abnormal temperature on the display screen.

[0038] In the supporting auxiliary system, the power supply system 14 adopts the mode of "2kW vehicle-mounted diesel generator + 10kWh lithium battery pack + mains power interface".

At the same time, each module is equipped with a protective fence or protective cover to prevent the audience from accidentally touching moving parts or high-voltage equipment.

[0039] The working process of this embodiment is as follows:

[0040] 1. Movement and Deployment: After the vehicle-mounted carrier 1 arrives at the designated science popularization site through the navigation system, the driver operates the hydraulic outriggers to extend and support the ground, and then controls the expansion cabin 2 to unfold. The staff starts the power supply system 14 through the human-machine interaction terminal 13 and selects the "automatic deployment" mode. The main controller 12 automatically starts the initialization test of each module to ensure the normal operation of the equipment.

[0041] 2. Demonstration and Operation: After entering the central interactive area 3, visitors can learn about the content of each module through the human-computer interaction terminal 13, and then proceed to the corresponding module's display area 4 to participate in the interaction. For example, in front of the human body sensing control display module 7, visitors can control the movement of the mechanical arm through body postures; in the 3D modeling and printing display module 8, visitors can scan personal items and print small models; in the VR simulation experience unit, visitors wear VR headsets to experience aerospace scenarios. The main controller 12 monitors the operating status and environmental parameters of each module in real time. When an abnormality occurs (such as equipment overload or excessive temperature), it automatically activates the alarm device and takes emergency measures (such as shutting down the module and starting the cooling system).

[0042] 3. Recycling and Relocation: After the science popularization activity, the staff can start the "recycling mode" through the human-computer interaction terminal 13. The main controller 12 controls each module to shut down automatically. Then the staff can organize the equipment and retract the extended cabin 2. The hydraulic outriggers will retract, and the vehicle carrier 1 can leave the site and go to the next science popularization site.
