Description

[0012] The utility model has the beneficial effects that:

[0013] This invention creates a low-vacuum environment through a vacuum pipeline, reducing air resistance. A base provides support for the entire system, and a suspension component is mounted on the base, enabling the test vehicle to levitate. The outer shell of the test vehicle carries passengers and various components, while its internal space houses environmental control and safety monitoring components. The environmental control component monitors the air composition within the space in real time and adjusts accordingly to provide a suitable environment for passengers.

Aerodynamic resistance increases parabolically with train speed and linearly with the pipeline vacuum level, blockage ratio, and ambient temperature. For example, air resistance increases significantly when the vacuum level decreases (air pressure increases) or the blockage ratio increases. This test system needs to meet the vehicle's operating conditions under different air pressures, speeds, and blockage ratios to study the vehicle's dynamic stability requirements under various conditions.

[0024] like Figs. 1-4 As shown, this embodiment provides a vacuum tube maglev transportation manned test system, including:

[0025] Vacuum pipe 1,

[0026] Base 2, wherein the base 2 is disposed inside the vacuum pipe 1,

[0027] Suspension component 3, which is disposed on the base 2.

[0028] Test vehicle body 4, which is mounted on the suspension assembly 3, includes,

[0029] The outer shell 5 is disposed on the suspension component 3, and the outer shell 5 has a load-bearing space 501 inside.

[0030] Environmental control component 6 is disposed within the bearing space 501 of the outer casing 5. The environmental detection component is used to monitor the air composition within the bearing space 501.

[0031] Safety monitoring component 7 is disposed within the bearing space 501 of the outer casing 5 and is used to monitor the vehicle body and passengers.

[0032] In this embodiment, a low-vacuum environment is created through the vacuum pipe 1 to reduce air resistance. The base 2 provides support for the entire system, and the suspension component 3 is mounted on the base 2, enabling the test vehicle body 4 to levitate. The outer shell 5 of the test vehicle body 4 carries passengers and various components, while its internal carrying space 501 accommodates the environmental control component 6 and the safety monitoring component 7. The environmental control component 6 monitors the air composition within the carrying space 501 in real time and makes corresponding adjustments to provide a suitable environment for passengers. The safety monitoring component 7 monitors the status of the vehicle body and passengers to ensure operational safety. In engineering applications, an absolute vacuum cannot be achieved within the vacuum pipe 1. Although the air density within the vacuum pipe 1 is extremely low (close to a vacuum state), air resistance will still be generated when the train runs at high speed. Aerodynamic resistance increases parabolically with train speed and linearly with pipe vacuum degree, blockage ratio, and ambient temperature. For example, when the vacuum degree decreases (air pressure increases) or the blockage ratio increases, air resistance will increase significantly. This test system needs to meet the vehicle operation conditions under different air pressures, speeds, and blockage ratios to study the dynamic stability requirements of the vehicle under various conditions.

[0033] A complete manned test system for the Vacuum Tube 1 maglev transportation was constructed, providing a basic platform for related technology research and product development. Basic monitoring and control of the manned environment and operational safety were achieved, providing safety assurance for the manned operation of the Vacuum Tube 1 maglev transportation system.

[0034] Furthermore, the vacuum pipe 1 has a first opening 101, and the outer shell 5 has a second opening 502; it also includes a telescopic channel 13, a first door 11, and a second door 12. The first door 11 is located at the first opening 101, and the second door 12 is located at the second opening 502. The telescopic channel 13 is located inside the vacuum pipe 1. One end of the telescopic channel 13 is connected to the first opening 101, and the other end of the telescopic channel 13 is used to connect to the second opening 502.

[0035] In this embodiment, when personnel need to enter or exit the test vehicle body 4, the telescopic channel 13 extends, with one end connecting to the first opening 101 of the vacuum pipe 1 and the other end connecting to the second opening 502 of the outer shell 5 of the test vehicle body 4. After connection, an independent and sealed vacuum environment is formed inside the telescopic channel 13. Then, the venting valve 15 can be opened manually or automatically to allow air to enter the telescopic channel, and then the first door 11 and the second door 12 can be opened. Personnel can then pass between the vacuum pipe 1 and the test vehicle body 4 through the telescopic channel 13. The telescopic channel 13 includes a corresponding door frame and a telescopic section in the middle. The telescopic section can be an elastic cover with a telescopic frame inside, allowing passengers to walk through it. It can also be used to evacuate personnel after operation or in case of an emergency. This provides a safe and convenient personnel access channel, solving the problem of personnel entering and exiting the test vehicle body 4 in a vacuum environment. In emergency situations, it provides a reliable evacuation route, enhancing the safety of the system.

[0036] Furthermore, the outer shell 5 has at least one positioning groove 102, and at least one of the positioning grooves 102 is located circumferentially in the first opening 101. The telescopic channel 13 has at least one positioning post 1301 at one end near the first door 11, and the positioning post 1301 is used to insert into the positioning groove 102.

[0037] In this embodiment, the positioning post 1301 at the end of the telescopic channel 13 near the first door 11 is inserted into the positioning groove 102 on the outer shell 5 of the test vehicle body 4, located circumferentially around the first opening 101. This method of connection precisely determines the relative position of the telescopic channel 13 and the test vehicle body 4, ensuring accurate docking and guaranteeing smooth and safe personnel access. A sensor probe can also be installed in the positioning groove 102 to improve positioning stability, enhance the accuracy and reliability of docking between the telescopic channel 13 and the test vehicle body 4, and reduce safety risks caused by inaccurate docking. This facilitates rapid and accurate docking operations in multiple tests, improving testing efficiency.

[0038] Furthermore, it also includes a sealing gasket 14 and a venting valve 15. The sealing gasket 14 is disposed on the telescopic channel 13 and is disposed at the cross-section of the telescopic channel 13 near the second opening 502. The venting valve 15 is disposed on the first door body 11.

[0039] In this embodiment, the sealing gasket 14 is located at one end of the telescopic channel 13 near the second opening 502. When the telescopic channel 13 is connected to the test vehicle body 4, the sealing gasket 14 fills the gap between them to prevent air leakage and maintain a low vacuum environment within the vacuum pipeline 1. The venting valve 15 is located on the first door body 11 and can be opened manually or automatically to allow air into the telescopic channel 13, preventing a vacuum environment from forming within the channel and preparing for subsequent door opening. The sealing gasket 14 ensures the stability of the low vacuum environment within the vacuum pipeline 1, which is beneficial for the smooth conduct of the test. The venting valve 15 provides a rapid and effective safety measure in emergency situations, ensuring the safety of personnel and equipment.

[0040] Furthermore, the suspension component 3 includes a magnetic track 301 and a dewar 302. The magnetic track 301 is disposed on the base 2, and the dewar 302 is disposed at the bottom of the test vehicle body 4.

[0041] In this embodiment, the magnetic track 301 is fixed to the base 2, generating a magnetic field. The Dewar 302 at the bottom of the test vehicle 4 contains high-temperature superconducting material. Under the influence of the magnetic field, the test vehicle 4 levitates due to the high-temperature superconducting pinning effect. By controlling the characteristics of the magnetic field of the magnetic track 301, the test vehicle 4 can achieve levitation, movement, and other operational operations. The levitation assembly 3 using the magnetic track 301 and Dewar 302 enables the test vehicle 4 to operate magnetically within the vacuum pipe 1, providing crucial support for research on magnetic levitation transportation technology in the vacuum pipe 1. It also provides an operable experimental platform for in-depth research on the performance of magnetic levitation technology in a vacuum environment.

[0042] Furthermore, the environmental control component 6 includes an air compressor 601, an air compression tank 602, and an air conditioning component 603. The air conditioning component 603 and the air compression tank 602 are both connected to the air compressor 601. The environmental control component 6 also includes an air pressure regulator 604, a CO2 adsorbent 605, and a CO2 monitor 606. The air pressure regulator 604, the CO2 adsorbent 605, and the CO2 monitor 606 are all disposed within the outer casing 5.

[0043] In this embodiment, an air compressor 601 compresses and stores air in an air compression tank 602, providing air to the test vehicle as needed. An air conditioning unit 603 regulates the temperature and humidity inside the vehicle. An air pressure regulator 604 adjusts the air pressure inside the vehicle. A CO2 monitor monitors the carbon dioxide concentration in real time; when the concentration exceeds the standard, a CO2 adsorbent activates to reduce the carbon dioxide concentration, jointly creating a suitable environment for passengers. A relatively complete passenger-carrying environmental control system is constructed, capable of real-time monitoring and adjustment of various environmental parameters, ensuring the comfort and safety of passengers and test personnel. This provides an experimental means for studying human adaptability and environmental control technology under different environmental conditions.

[0044] Furthermore, the safety monitoring component 7 includes a camera 701 and a sensor component 702, both of which are disposed inside the housing 5. The sensor component 702 includes a temperature sensor 721, a barometric pressure sensor 722, a triaxial accelerometer 723, and a laser displacement sensor 724.

[0045] In this embodiment, camera 701 captures real-time images of the vehicle interior, while temperature sensor 721, air pressure sensor 722, triaxial accelerometer 723, and laser displacement sensor 724 collect real-time data on temperature, air pressure, acceleration, and displacement, respectively. This data is transmitted to the control system for analysis and processing to monitor the status of the test vehicle 4 and passengers, ensuring operational safety. This achieves comprehensive safety monitoring of the test vehicle 4 and passengers, enabling timely detection and early warning of potential safety issues. It provides rich data support for fault diagnosis and handling during the test, improving the system's safety and reliability.

[0046] Furthermore, it also includes a traction braking assembly 8, which includes a stator 801 and a mover 802. The stator 801 is disposed on the base 2, and the mover 802 is disposed at the bottom of the test vehicle body 4.

[0047] In this embodiment, the stator 801 is fixed to the base 2, and the mover 802 is installed at the bottom of the test vehicle body 4. When the stator 801 is energized, it generates a magnetic field, which interacts with the mover 802 to generate an electromagnetic force, propelling the test vehicle body 4 forward. During braking, by changing the characteristics of the magnetic field of the stator 801, the mover 802 is subjected to a reverse electromagnetic force, thereby decelerating and stopping the test vehicle body 4. The traction braking assembly 8 provides reliable power and braking means for the test vehicle body 4, enabling the test to simulate actual operating conditions. This facilitates the study of the performance of the test vehicle body 4 under different operating conditions and provides data support for the optimization of the vacuum pipeline 1 maglev transportation technology.

[0048] Furthermore, it also includes a seat 9 and a display 10, both of which are disposed within the housing 5. The display 10 is connected to both the environmental control component 6 and the safety monitoring component 7.

[0049] In this embodiment, seat 9 provides support for passengers. Display 10 is connected to environmental control component 6 and safety monitoring component 7, receiving and displaying relevant data in real time, such as in-vehicle temperature, air pressure, carbon dioxide concentration, and vehicle operating status. This enhances the passenger's riding experience and sense of security, while providing test personnel with a convenient way to view data, facilitating test operation and management. It also enhances the system's human-computer interaction capabilities, improving the efficiency and controllability of the test.

[0050] Furthermore, the safety monitoring component 7 also includes a laser displacement sensor 724 and a vital signs monitoring system 704, both of which are disposed within the outer casing 5.

[0051] In this embodiment, the laser displacement sensor 724 monitors the distance between the vehicle and surrounding objects in real time and transmits the data to the control system. The vital signs monitoring system 704 collects passenger vital signs data through wearable devices or in-vehicle sensors and also transmits it to the control system. The control system analyzes this data, issues an alarm promptly when an anomaly is detected, and takes appropriate measures. This further improves the safety monitoring system, providing more comprehensive protection from both passenger health and vehicle operation safety perspectives. It can promptly detect and respond to potential safety risks, improving the safety and reliability of the vacuum tube 1 maglev transportation manned test system.
