Description

Technology Field

[0001] The present invention relates to a hyperloop system capable of magnetic field communication and a method for controlling the same. Background Technology

[0002] The hyperloop transport system is a technology that transports vehicles at high speeds of over 1,200 km / h using magnetic levitation and propulsion inside a tube in a near-vacuum state.

[0003] For example, it is recently gaining attention as a technology that enables ultra-high-speed transportation by utilizing sealed, near-vacuum tubes as railway tracks to reduce noise and air resistance compared to Maglev.

[0004] A hyperloop transport system comprises a tube isolated from the outside to maintain its interior in a low-pressure state, i.e., a near-vacuum state; a vehicle traveling inside the near-vacuum tube; a linear synchronous motor (LSM) configured to generate thrust in the longitudinal direction of the tube, consisting of a stator provided on the track side of the tube and a rotor provided on the vehicle corresponding to the tube-side stator; a levitation guide means for levitating the vehicle using magnetic force and positioning the vehicle on a concentric axis within the tube; and a power supply device installed on the upper inner surface of the tube and the corresponding outer surface of the vehicle to supply power to the vehicle.

[0005] In a hyperloop, a train is propelled via magnetic levitation using superconductivity inside a tube that maintains a near-vacuum state; to preserve this vacuum, the tube is constructed of metal or concrete, and methods to minimize connection points are being applied as the norm.

[0006] To maintain this near-vacuum state, a method is applied in which vacuum sensors, crack detection sensors, etc., are installed inside and outside the tube to monitor the airtightness of the tube.

[0007] In this case, sensors are attached to the inside and outside of the tube, and sensing data is transmitted to the internal train or control system, or the external control system. However, since the hyperloop is made of metal or concrete, there is a problem in that commonly used high-frequency (800 MHz to 2.2 GHz) communication technology is difficult to use due to severe shielding or attenuation.

[0008] In addition, there is a need for a device to reduce or avoid interference caused by the magnetic fields generated by the superconductors used to drive the hyperloop vehicle.

[0009] Therefore, there is a growing need for systems and methods to resolve these problems. Prior art literature

[0014] A hyperloop system for achieving the above technical objectives comprises: a hyperloop vehicle; a tube having an internal space sealed from the external atmospheric pressure side and formed to surround the path of travel of the hyperloop vehicle and maintaining a near-vacuum state; and an electronic rail disposed inside the tube to move the hyperloop vehicle; wherein at least one first sensor for measuring information related to the airtight state for maintaining the near-vacuum state of the tube is disposed inside the tube, and at least one second sensor for measuring information related to the airtight state is disposed outside the tube; the hyperloop vehicle further comprises an internal monitoring unit that communicates with at least one of the first sensor and the second sensor to generate a signal for controlling the hyperloop vehicle, and the external monitoring unit outside the tube further comprises an external monitoring unit that communicates with at least one of the first sensor, the second sensor, and the internal monitoring unit to generate a signal for controlling the hyperloop vehicle, wherein only communication using a magnetic field is possible between the first sensor and the second sensor, and only communication using a magnetic field is possible between the internal monitoring unit and the second sensor.

[0015] In addition, the first sensor and the second sensor can generate magnetic field information by changing the magnetic field or resonance frequency according to the information being sensed.

[0016] In addition, the first sensor and the second sensor may generate magnetic field information by increasing the magnetic field or resonance frequency as the result value of the sensing information increases, and generate magnetic field information by decreasing the magnetic field or resonance frequency as the result value of the sensing information decreases.

[0017] In addition, the first sensor and the second sensor may pass the magnetic field information through a filter to eliminate magnetic field interference induced by the hyperloop vehicle, and change the magnetic field information that has passed through the filter into a digital or analog signal and transmit it through the magnetic field communication.

[0018] In addition, both electromagnetic wave communication and magnetic field communication are possible between the first sensor and the internal monitoring unit, and both electromagnetic wave communication and magnetic field communication are possible between the second sensor and the external monitoring unit, and since there is no frequency overlap between the electromagnetic wave communication signal and the magnetic field communication signal, they can be combined and communicated through a mixer.

[0019] In addition, the magnetic field communication between the first sensor and the second sensor and the magnetic field communication between the internal monitoring unit and the second sensor can be performed only when the hyperloop vehicle does not pass through the area where the first sensor and the second sensor are placed.

[0020] In addition, the first sensor and the second sensor may include a vacuum sensor that senses whether the vacuum is maintained and a crack detection sensor that senses a crack on the tube that prevents the airtight state from being maintained.

[0021] In addition, the tube may be composed of at least one of metal and concrete to maintain the above-mentioned airtight state.

[0022] Meanwhile, in a control method of a system comprising: a hyperloop vehicle according to another embodiment of the present invention; a tube having an internal space sealed from the external atmospheric pressure side and formed to surround the path of travel of the hyperloop vehicle and maintaining a near-vacuum state; and an electronic rail disposed inside the tube to move the hyperloop vehicle, wherein at least one first sensor for measuring information related to a sealing state for maintaining a near-vacuum state of the tube is disposed inside the tube, and at least one second sensor for measuring information related to the sealing state is disposed outside the tube, and the hyperloop vehicle further comprises an internal monitoring unit that communicates with at least one of the first sensor and the second sensor to generate a signal for controlling the hyperloop vehicle, and further comprises an external monitoring unit outside the tube that communicates with at least one of the first sensor, the second sensor and the internal monitoring unit to generate a signal for controlling the hyperloop vehicle, and only communication using a magnetic field is possible between the first sensor and the second sensor, and only communication using a magnetic field is possible between the internal monitoring unit and the second sensor.

[0023] Additionally, the first sensor and the second sensor may generate magnetic field information by changing the magnetic field or resonance frequency according to the information being sensed, increase the magnetic field or resonance frequency as the result of the information being sensed increases to generate the magnetic field information, and decrease the magnetic field or resonance frequency as the result of the information being sensed decreases to generate the magnetic field information.

[0024] In addition, the first sensor and the second sensor may pass the magnetic field information through a filter to eliminate magnetic field interference induced by the hyperloop vehicle, and change the magnetic field information that has passed through the filter into a digital or analog signal and transmit it through the magnetic field communication.

[0025] In addition, both electromagnetic wave communication and magnetic field communication are possible between the first sensor and the internal monitoring unit, and both electromagnetic wave communication and magnetic field communication are possible between the second sensor and the external monitoring unit, and since there is no frequency overlap between the electromagnetic wave communication signal and the magnetic field communication signal, they can be combined and communicated through a mixer.

[0026] In addition, the magnetic field communication between the first sensor and the second sensor and the magnetic field communication between the internal monitoring unit and the second sensor can be performed only when the hyperloop vehicle does not pass through the area where the first sensor and the second sensor are placed. Effects of the invention

[0027] The present invention can resolve the problems of the prior art by proposing a communication system that utilizes magnetic field communication for communication between the inside and outside of a hyperloop while avoiding interference caused by superconductors and propulsion induction coils.

[0038] FIG. 1 is an explanatory diagram showing a hyperloop transport system to which the present invention is applied.

[0039] As illustrated in FIG. 1, a hyperloop transport system generally allows a vehicle to travel at a high speed of over 1,200 km / h inside a tube in a near-vacuum state using magnetic levitation and propulsion. To prevent a decrease in vehicle speed due to air resistance inside the tube, a compressor is provided at the front of the vehicle to compress the air flowing into the front of the vehicle and discharge it to the rear. Additionally, in FIG. 1, it can be seen that the compressor fan is shown at the front of the vehicle.

[0040] In other words, a vehicle traveling at high speed inside a tube is limited to a maximum speed by the Kantrowitz limit phenomenon. As the maximum speed approaches the speed of sound, the flow velocity passing between the tube and the vehicle approaches zero, causing a choking phenomenon. To overcome this limit, an axial compressor is installed at the front of the vehicle to avoid the choking phenomenon.

[0041] A hyperloop transport system comprises a tube isolated from the outside to maintain its interior in a low-pressure state, i.e., a near-vacuum state; a vehicle traveling inside the near-vacuum tube; a linear synchronous motor (LSM) configured to generate thrust in the longitudinal direction of the tube, consisting of a stator provided on the track side of the tube and a rotor provided on the vehicle corresponding to the tube-side stator; a levitation guide means for levitating the vehicle using magnetic force and positioning the vehicle on a concentric axis within the tube; and a power supply device installed on the upper inner surface of the tube and the corresponding outer surface of the vehicle to supply power to the vehicle.

[0042] FIG. 2 is a diagram showing the schematic configuration of a hyperloop system according to one embodiment of the present disclosure.

[0043] Referring to FIG. 2, a hyper-tube system (100) according to one embodiment of the present disclosure may include a hyper-tube vehicle (110), a tube unit (120), a guide way (130), an electric rail (140), a seat (210), and a cover (220).

[0044] The hyperloop vehicle (110) may include an electromagnet (112). The electric rail (140) may include a propulsion electric rail (141) and a floating electric rail (142). The seat (210) may include an outer portion (212), an inner portion (214), and a middle portion (not shown).

[0045] The hypertube vehicle (110) moves along the longitudinal direction of the tube section (120) inside the tube section (120). The hypertube vehicle (110) is separated from the guideway (130) by a levitation electromagnetic rail (142). The hypertube vehicle (110) can move using the propulsion force provided by the propulsion electromagnetic rail (141). Since the interior of the tube section (120) is in a sub-vacuum state, the air resistance acting on the hypertube vehicle (110) during driving is very small. Accordingly, the hypertube vehicle (110) can move at a high speed of up to 1,200 km / h. The hypertube vehicle (110) may be a maglev levitation train. The hypertube vehicle (110) may be formed in the shape of a capsule.

[0046] At least a portion of the hyperloop vehicle (110) may be formed of an electromagnetic shielding material. The electromagnetic shielding material may be a soft magnetic material. The soft magnetic material may be a nickel alloy or a cobalt alloy. By forming at least a portion of the hyperloop vehicle (110) with an electromagnetic shielding material, passengers can be protected from strong electromagnetic fields generated from the electromagnet (112) and the electromagnetic rail (140).

[0047] At least one electromagnet (112) may be installed in the hyperloop vehicle (110). The electromagnet (112) may be positioned spaced apart from the electromagnetic rail (140) and facing the electromagnetic rail (140). The electromagnet (112) may be a superconducting electromagnet. As the hyperloop vehicle (110) moves, the electromagnet (112) may generate a strong electromagnetic field.

[0048] The tube section (120) is formed to surround the travel path of the hypertube vehicle (110). The hypertube vehicle (110), guideway (130), and electromagnetic rail (140), etc., may be arranged inside the tube section (120). The interior of the tube section (120) may be in a sub-vacuum state at a pressure level of 0.001 atmospheres. The tube section (120) may be formed in a circular cylinder shape.

[0049] The guideway (130) may be positioned adjacent to the inner surface of the tube section (120). The guideway (130) may be positioned along the travel path of the hypertube vehicle (110). The guideway (130) may be formed of a non-conductive material. The guideway (130) may be formed of concrete.

[0050] The propulsion electromagnetic rail (141) provides propulsion to the hypertube vehicle (110). The propulsion electromagnetic rail (141) may be positioned adjacent to the guideway (130) along the path of the hypertube vehicle (110). The propulsion electromagnetic rail (141) may be positioned between the hypertube vehicle (110) and the guideway (130). In providing propulsion to the hypertube vehicle (110) by the propulsion electromagnetic rail (141), a strong electromagnetic field may be generated from the propulsion electromagnetic rail (141).

[0051] The hypertube vehicle (110) is separated from the guideway (130) by the levitating electromagnetic rail (142). The levitating electromagnetic rail (142) may be positioned adjacent to the propulsion electromagnetic rail (141) along the travel path of the hypertube vehicle (110). The levitating electromagnetic rail (142) may be positioned between the hypertube vehicle (110) and the propulsion electromagnetic rail (141). As the hypertube vehicle (110) is separated from the guideway (130) by the levitating electromagnetic rail (142), a strong electromagnetic field may be generated from the levitating electromagnetic rail (142).

[0052] A seat (210) is placed inside the hypertube vehicle (110) so that a passenger of the hypertube vehicle (110) may be seated. There may be multiple seats (210). The seat (210) may be formed to enclose most of the passenger's body. The seat (210) may be electromagnetically connected to a cover (220). At least a portion of the seat (210) may be formed of an electromagnetic shielding material to protect the passenger from the electromagnetic field generated from the electromagnet (112) and the electromagnetic rail (140). The seat (210) may be formed as a multi-layer structure including an outer portion (212), an inner portion (214), and at least one intermediate portion.

[0053] The outer portion (212) is formed on the outermost side of the seat (210). The outer portion (212) may be formed of an electromagnetic shielding material. The inner portion (214) is formed on the innermost side of the seat (210) to come into contact with the passenger's body. The inner portion (214) may be formed of a cushioning material. The cushioning material may be a cushion. The middle portion is formed between the outer portion (212) and the inner portion (214). There may be multiple middle portions. The middle portion may be any one of an electromagnetic shielding material, a cushioning material, a vibration insulating material, and a sound absorbing material. The electromagnetic shielding material may be a soft magnetic material. The soft magnetic material may be a nickel alloy or a cobalt alloy. The outer portion (212), the inner portion (214), and at least one middle portion may be formed integrally. The sheet (210) can be grounded by connecting it to a part of the hyperloop vehicle (110) using a conductor such as gold, silver, and copper.

[0054] The cover (220) may be configured to cover at least a portion of the body of a passenger seated on the seat (210). The cover (220) may be configured to be detachable from the seat (210). The cover (220) may be formed of an electromagnetic shielding material. The cover (220) may be electromagnetically connected to the seat (210). By being electromagnetically connected to the cover (220) and the seat (210), an electromagnetic closed loop is formed to effectively protect the passenger from the electromagnetic field. The cover (220) may be formed in a multi-layer structure.

[0055] Meanwhile, Hyperloop is a next-generation mode of transportation that creates a near-vacuum inside a tube and accelerates passenger cars (pods) one by one to travel at high speeds. Since it travels inside a tube, there are issues that need to be resolved for safety.

[0056] For example, air leaks inside the passenger car can lead to fatal accidents, so it is necessary to measure leaks in the passenger car while it is in operation.

[0057] In addition, since the vehicle travels inside the tube, there is a problem that wireless communication for passengers is disrupted.

[0058] In particular, in Hyperloop systems, airtightness of the tube is crucial for maintaining a near-vacuum state, but there is a problem where maintaining airtightness is difficult due to the embedding of communication lines between the inside and outside.

[0059] FIG. 3 is a drawing illustrating an example of a hypertube having almost no gaps to maintain a near-vacuum state in relation to the present invention, in which wireless communication signals between internal and external sensors and monitoring devices are shielded by a material such as concrete or metal.

[0060] Referring to FIG. 3, the hypertube is propelled by magnetic levitation using superconductivity inside a tube (120) that maintains a near-vacuum state, and to maintain the near-vacuum state, the tube (120) is made of metal or concrete (200), and a method of minimizing connection points is predominantly applied.

[0061] To maintain such a vacuum state, a method is applied in which sensors (300, vacuum sensors, crack detection sensors, etc.) are installed inside and outside the tube (120) to monitor the airtightness of the tube (120).

[0062] At this time, each sensor (300) is attached to the inside and outside of the tube (120), and the sensing data is transmitted to the train (110) or control system inside, or to the control system outside, etc. However, the hyper tube (120) is made of metal or concrete material (200), and there is a problem that the commonly used high-frequency (800 MHz to 2.2 GHz) communication technology is difficult to use because of severe shielding or attenuation.

[0063] That is, the hypertube (120) has almost no gaps to maintain a near-vacuum state, and the material is concrete or metal (200), so wireless communication signals between internal and external sensors (300) and monitoring devices are shielded. Therefore, there is a problem that wired communication must be considered through the embedding of communication lines penetrating the tube (120) for communication inside and outside the hypertube (120).

[0064] In addition, since it is interfered with by the magnetic field generated by the superconductor used to drive the hyperloop vehicle (110), a device is required to reduce or avoid this.

[0065] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to propose a communication system capable of avoiding interference caused by superconductors and propulsion induction coils while utilizing magnetic field communication for communication between the inside and outside of a hyperloop.

[0066] According to the present invention, at least one first sensor for measuring information related to a sealing state for maintaining a vacuum in a tube is disposed inside the tube, and at least one second sensor for measuring information related to a sealing state is disposed outside the tube, and the hyperloop vehicle further includes an internal monitoring unit that communicates with at least one of the first sensor and the second sensor to generate a signal for controlling the hyperloop vehicle, and further includes an external monitoring unit outside the tube that communicates with at least one of the first sensor, the second sensor and the internal monitoring unit to generate a signal for controlling the hyperloop vehicle. At this time, both electromagnetic wave communication and magnetic field communication are possible between the first sensor and the internal monitoring unit, and both electromagnetic wave communication and magnetic field communication are possible between the second sensor and the external monitoring unit. Since there is no frequency overlap between the electromagnetic wave communication signal and the magnetic field communication signal, they can be combined through a mixer to enable communication. However, if the hyperloop vehicle does not pass through the area where the first sensor and the second sensor are placed, the communication may be performed via magnetic field communication between the first sensor and the second sensor. Additionally, a hyperloop system may be proposed in which only magnetic field communication is possible between the first sensor and the second sensor, and only magnetic field communication is possible between the internal monitoring unit and the second sensor.

[0067] Since the magnetic field communication applied in the present invention uses a low frequency (128 kHz), it has high permeability, so there is little signal loss even when passing through a hypertube, making it easy to use for communication inside and outside the tube.

[0068] Magnetic field communication may also be referred to as a near-field magnetic induction (NFMI) communication system.

[0069] The magnetic field is strong at distances within wavelength / 2Π, and it penetrates well even in very poor media such as underground, water, and concrete.

[0070] In addition, the ISO / IEC 15149 Magnetic Field Area Network (MFAN) has been proposed as a magnetic field communication standard.

[0071] By utilizing magnetic field communication for communication between the inside and outside of the hyperloop, wireless communication is possible without connecting wires.

[0072] However, since existing proposed magnetic field communication methods were designed considering general communication situations, they do not take into account frequency selection considering transmission distance or methods for integration with sensor systems.

[0073] However, since it is interfered with by the magnetic fields generated by the superconductors used for hyperloop propulsion, a device is required to reduce or avoid this interference.

[0074] FIG. 4 illustrates an example of a hyperloop system capable of magnetic field communication proposed by the present invention.

[0075] Referring to FIG. 4, the hypertube vehicle (110) has an internal space sealed from the external atmospheric pressure side and has a tube (120) formed to maintain a vacuum state that surrounds the path of the hypertube vehicle (100), and an electronic rail (140) disposed inside the tube (120) to move the hypertube vehicle (1100).

[0076] At this time, at least one first sensor (310a, 310b) for measuring information related to the airtight state for maintaining a vacuum in the tube (120) may be placed inside the tube (120).

[0077] Additionally, at least one second sensor (320a, 320b) for measuring information related to the confidentiality status may be placed outside the tube (120).

[0078] The hyperloop vehicle (110) may further include an internal monitoring unit (500) that communicates with at least one of the first sensor (310a, 310b) and the second sensor (320a, 320b) to generate a signal to control the hyperloop vehicle (110).

[0079] Additionally, the tube (120) may further include an external monitoring unit (400) that communicates with at least one of a first sensor (310a, 310b), a second sensor (320a, 320b), and an internal monitoring unit (500) to generate a signal for controlling the hypertube vehicle (110).

[0080] In this case, the present invention allows only communication using a magnetic field between the first sensor (310a, 310b) and the second sensor (320a, 320b), and only communication using a magnetic field between the internal monitoring unit (500) and the second sensor (320a, 320b), thereby resolving the problems of the prior art.

[0081] Here, the first sensor (310a, 310b) and the second sensor (320a, 320b) can generate magnetic field information by changing the magnetic field or resonant frequency according to the information being sensed.

[0082] Specifically, the first sensor (310a, 310b) and the second sensor (320a, 320b) can generate magnetic field information by increasing the magnetic field or resonance frequency as the result value of the information being sensed increases, and generate magnetic field information by decreasing the magnetic field or resonance frequency as the result value of the information being sensed decreases.

[0083] In addition, the first sensor (310a, 310b) and the second sensor (320a, 320b) may apply a method of passing magnetic field information through a filter to eliminate magnetic field interference induced by the hyperloop vehicle (110), and changing the magnetic field information that has passed through the filter into a digital or analog signal and transmitting it through magnetic field communication.

[0084] In addition, both electromagnetic wave communication and magnetic field communication are possible between the first sensor (310a, 310b) and the internal monitoring unit, and

[0085] Both electromagnetic wave communication and magnetic field communication are possible between the second sensor (320a, 320b) and the external monitoring, and since there is no frequency overlap between the electromagnetic wave communication signal and the magnetic field communication signal, they can be combined through a mixer to enable communication.

[0086] In addition, magnetic field communication between the first sensor (310a, 310b) and the second sensor (320a, 320b) and magnetic field communication between the internal monitoring unit and the second sensor may be performed only when the hyperloop vehicle does not pass through the area where the first sensor (310a, 310b) and the second sensor (320a, 320b) are placed.

[0087] Additionally, the first sensor (310a, 310b) and the second sensor (320a, 320b) may include a vacuum sensor that senses whether a vacuum is maintained and a crack detection sensor that senses a crack on the tube that prevents the airtight state from being maintained.

[0088] FIG. 5 illustrates an example of a transmission module that converts sensor measurements into magnetic field signals in relation to the present invention.

[0089] Referring to FIG. 5, the sensor (300) transmits information by directly linking the measurement result to a variable capacitor, and if the result value is large, the magnetic field or resonant frequency is increased, and if the result value is small, the magnetic field or resonant frequency is decreased.

[0090] FIG. 6 illustrates an example of a receiving module that estimates the degree of vacuum based on the strength of a magnetic field signal in relation to the present invention.

[0091] Referring to Fig. 6, the interference removal unit uses a band stop filter to remove signals of the corresponding frequency in order to remove magnetic field interference generated in the hyperloop propulsion system.

[0092] Although it is described in Fig. 6 as a simple LC circuit equivalent to a notch filter, it can be modified by analyzing the frequency of the interference signal and designing a precise filter.

[0093] In addition, the communication section after the decoder is capable of both digital and analog communication depending on the function of the connected module.

[0094] FIG. 7 illustrates an example of a magnetic field-electromagnetic wave communication integration module in relation to the present invention.

[0095] Referring to Fig. 7, since electromagnetic communication can be utilized in internal-internal and external-external communication, the utility can be increased if an electromagnetic communication device is utilized together with a magnetic field communication device.

[0096] An antenna structure in which electromagnetic and magnetic field communication devices coexist can be implemented through a mixer.

[0097] As long as there is no overlap between the magnetic field (red) communication frequency and the electromagnetic wave (blue) communication frequency in Fig. 7, the two communication methods can generate signals from a single transmitter.

[0098] FIG. 8 illustrates an example of a communication flowchart of a transmitting end for digital communication and analog communication in relation to the present invention.

[0099] Figure 8(a) relates to digital communication, which is transmitted through the process of sensing (S1) of a vacuum sensor, ADC conversion (S2), waveform generation (S3), and magnetic field radiation (S4).

[0100] In addition, Figure 8(b) relates to analog communication, which is transmitted through the process of sensing (S11) of a vacuum sensor and magnetic field radiation (S4).

[0101] A system comprising a tube having an internal space sealed from the external atmospheric pressure side of the hyperloop vehicle and maintaining a subvacuum state formed to surround the path of the hyperloop vehicle, and an electronic rail disposed inside the tube to move the hyperloop vehicle, can operate in the following order.

[0102] At least one first sensor is disposed inside the tube to measure information related to a sealing state for maintaining a vacuum, and at least one second sensor is disposed outside the tube to measure information related to a sealing state, and the hyperloop vehicle further includes an internal monitoring unit that communicates with at least one of the first sensor and the second sensor to generate a signal to control the hyperloop vehicle.

[0103] Additionally, the tube further includes an external monitoring unit outside the tube that generates a signal to control the hyperloop vehicle by communicating with at least one of a first sensor, a second sensor, and an internal monitoring unit, and communication between the first sensor and the second sensor is possible only using a magnetic field, and communication between the internal monitoring unit and the second sensor is possible only using a magnetic field.

[0104] Here, the first sensor and the second sensor can generate magnetic field information by changing the magnetic field or resonant frequency according to the information being sensed, increase the magnetic field or resonant frequency to generate magnetic field information as the result of the information being sensed increases, and decrease the magnetic field or resonant frequency to generate magnetic field information as the result of the information being sensed decreases.

[0105] In addition, the first sensor and the second sensor can pass magnetic field information through a filter to eliminate magnetic field interference induced by the hyperloop vehicle, and the magnetic field information passed through the filter can be converted into a digital or analog signal and transmitted via magnetic field communication.

[0106] In addition, both electromagnetic wave communication and magnetic field communication are possible between the first sensor and the internal monitoring unit, and both electromagnetic wave communication and magnetic field communication are possible between the second sensor and the external monitoring unit, and since there is no frequency overlap between the electromagnetic wave communication signal and the magnetic field communication signal, they can be combined through a mixer to enable communication.

[0107] In addition, magnetic field communication between the first sensor and the second sensor and magnetic field communication between the internal monitoring unit and the second sensor can be performed only when the hyperloop vehicle does not pass through the area where the first sensor and the second sensor are placed.
