Description

Technical Field

[0001] This invention relates to the fields of communication technology and power technology, and particularly to a master control device, a terminal device, and a common transmission system thereof. Background Technology

[0002] In 2020, the Fraunhofer Institute for ISE in Germany pioneered a concurrent scheme using a single photodetector, simultaneously achieving energy and signal transmission on a single photodetector and proposing a system architecture for co-transmission of energy and signal. However, their single photodetector struggles to meet the demands of high-speed data communication and cannot perform heat transfer.

[0003] In 2025, the Global Energy Interconnection European Research Institute, the Information and Communication Branch of State Grid Liaoning Electric Power Company, and the Laiwu Power Supply Company of State Grid Shandong Electric Power Company proposed architectures for energy-information co-transmission systems. The Global Energy Interconnection European Research Institute proposed an energy-information co-transmission system based on integrated photovoltaic and communication modules, primarily for power equipment condition monitoring. The Information and Communication Branch of State Grid Liaoning Electric Power Company proposed a more basic energy-information co-transmission system, where a laser source outputs a composite light of energy and communication light, which is separated using a wavelength division multiplexer. The energy light is converted into electrical energy by photovoltaic cells and stored in supercapacitors to power the central processing chip at the nodes. The signal carried by the communication light is processed by the central processing chip, sends commands to sensors, and transmits valid information back to the processor via uplink communication fiber. The Laiwu Power Supply Company of State Grid Shandong Electric Power Company also proposed a similar system architecture, using energy-information co-transmission to complete power management and uplink / downlink data transmission.

[0004] With the explosive growth of artificial intelligence technology, fields such as intelligent vehicles, micro base stations, intelligent computing centers, and intelligent robots have experienced leapfrog development. These highly intelligent systems often require ultra-high bandwidth data exchange, high energy density power, and efficient thermal management to achieve ultimate real-time response and perception capabilities.

[0005] In these highly integrated application scenarios, existing fiber optic transmission systems are no longer sufficient to meet the demands, and there is an urgent need for an "energy-information-heat integrated" transmission system that can simultaneously carry high-throughput data streams, high-power energy streams, and efficient heat streams. Summary of the Invention

[0006] The problem solved by this invention is how to simultaneously carry the transmission of high-throughput data streams, high-power energy streams, and efficient heat streams.

[0007] To address the above problems, the present invention provides a master control device, comprising: A first light source configured to generate a first transmitted optical signal; a second light source configured to generate a second transmitted optical signal; a central multiplexing unit configured to couple the first transmitted optical signal and the second transmitted optical signal to obtain a transmitted optical signal and output it to a hollow optical fiber for transmission; and a cooling unit configured to cool at least one of the first light source, the second light source, and the central multiplexing unit, the cooling unit comprising: a refrigerant cavity and a main control cooling pipe connected to the refrigerant cavity, the refrigerant cavity being configured to store a refrigerant medium, and the main control cooling pipe also being connected to the hollow optical fiber.

[0008] Accordingly, the present invention also provides a terminal device, which is connected to the main control device of the present invention via a hollow optical fiber, comprising: The system includes: a terminal multiplexing unit configured to divide the transmitted optical signal transmitted by the hollow optical fiber into a first received optical signal and a second received optical signal; a terminal conversion unit configured to obtain a first received electrical signal based on the first received optical signal; the terminal conversion unit is also configured to obtain a second received electrical signal based on the second received optical signal; a power supply unit configured to supply power to a load device based on the first received electrical signal; the load device is also configured to receive the second received electrical signal; and a terminal cooling pipeline connected to the hollow optical fiber.

[0009] Furthermore, the present invention also provides a common transmission system, comprising: The main control device is the main control device of the present invention; the terminal device is the terminal device of the present invention; the hollow optical fiber is connected between the main control device and the terminal device.

[0010] This invention provides a master control device, comprising: A first light source, configured to generate a first transmitted optical signal; a modulation unit, configured to modulate the first transmitted optical signal according to a second transmitted signal to obtain a transmitted optical signal; and a cooling unit, configured to cool at least one of the first light source and the modulation unit, the cooling unit comprising: a refrigerant cavity and a main control cooling pipe connected to the refrigerant cavity, the refrigerant cavity being configured to store a refrigerant medium, and the main control cooling pipe also being connected to a hollow optical fiber.

[0011] Accordingly, the present invention also provides a terminal device, which is connected to the main control device of the present invention via a hollow optical fiber, comprising: The system includes: a receiving and conversion unit configured to receive the transmitted optical signal transmitted by the hollow-core optical fiber and obtain a transmitted electrical signal based on the transmitted optical signal; a terminal demodulation unit configured to obtain a first received electrical signal and a second received electrical signal based on the transmitted electrical signal, wherein the power of the first received electrical signal is greater than the power of the second received electrical signal; a power supply unit configured to supply power to a load device based on the first received electrical signal; the load device further configured to receive the second received electrical signal; and a terminal cooling pipeline configured to cool at least one of the receiving and conversion unit, the terminal demodulation unit, the power supply unit, and the load device, wherein the terminal cooling pipeline is connected to the hollow-core optical fiber.

[0012] Furthermore, the present invention also provides a common transmission system, comprising: The main control device is the main control device of the present invention; the terminal device is the terminal device of the present invention; the hollow optical fiber is connected between the main control device and the terminal device.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages: In the technical solution of this invention, the main control device and the terminal device are connected by hollow optical fiber. This enables the transmission of higher power optical signals by utilizing the high loss threshold of the air core. It can also effectively reduce the transmission loss and latency of optical signals. Furthermore, it can utilize the internal space of the hollow optical fiber to transmit cold media, breaking the traditional logical framework of independent transmission of "energy, signal, and heat". This constructs a "energy-signal-heat" co-transmission system with deep physical layer integration, which is conducive to the realization of "zero-wiring" systems with high bandwidth and resistance to electromagnetic interference. It is also beneficial to meeting the needs of highly integrated application scenarios such as intelligent vehicles, micro base stations, intelligent computing centers, and intelligent robots.

[0014] In an optional embodiment of the present invention, the terminal conversion unit in the terminal device includes an on-chip optoelectronic integrated receiver chip, which includes a photodetector. The use of an on-chip optoelectronic integrated receiver chip achieves a balance between high output power and high-speed communication, and is also smaller and lower in cost, making it more suitable for highly integrated intelligent systems.

[0021] As can be seen from the background technology, existing fiber optic transmission systems are insufficient to meet the needs of highly intelligent systems.

[0022] Fiber optic transmission systems typically use traditional solid optical fibers (single-mode / multi-mode / multi-core) for energy and signal transmission. Traditional solid optical fibers (single-mode / multi-mode / multi-core) suffer from high loss and high transmission delay. Under high power injection, they exhibit severe stimulated Brillouin scattering and thermal damage, and are unsuitable as an effective medium for heat transfer.

[0023] Moreover, all fiber optic transmission systems are "energy-communication integrated" fiber optic transmission systems, and the energy storage photodetector and the high-speed communication photodetector in the downlink are two independent devices, which increases cost and size.

[0024] Furthermore, the application scenarios of the "energy-information dual-flow integration" fiber optic transmission system are mostly in the fields of power technology for drone communication and power equipment status monitoring, which are difficult to meet the needs of highly integrated application scenarios such as intelligent vehicles, micro base stations, intelligent computing centers and intelligent robots.

[0025] To address the technical problems, this invention provides a master control device, a terminal device, and a co-transmission system thereof. The technical solution of this invention connects the master control device and the terminal device via hollow-core optical fiber, enabling the transmission of higher-power optical signals by utilizing the high loss threshold of the air core. It also effectively reduces optical signal transmission loss and latency, and utilizes the internal space of the hollow-core optical fiber to transmit a cold medium. This breaks the traditional logical framework of independent transmission of "energy, signal, and heat," constructing a deeply integrated "energy-signal-heat" co-transmission system at the physical layer. This facilitates the realization of high-bandwidth, electromagnetic interference-resistant "zero-wiring" systems and meets the needs of highly integrated application scenarios such as intelligent vehicles, micro base stations, intelligent computing centers, and intelligent robots.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] refer to Figure 1 A schematic diagram of a common transmission system consistent with some embodiments of the present invention is shown. (Referring to the reference...) Figure 2 and Figure 3 ,in Figure 2 This is a schematic diagram of the main control device in a common transmission system consistent with some embodiments of the present invention; Figure 3 This is a schematic diagram of the structure of a terminal device in a common transmission system consistent with some embodiments of the present invention.

[0028] The co-transmission system includes a main control device 100, a terminal device 200, and a hollow optical fiber 102, wherein the hollow optical fiber 102 is connected between the main control device and the terminal device to realize independent transmission of energy, information, and heat.

[0029] The main control device 100 includes: a first light source 110 configured to generate a first transmitted optical signal; a second light source 120 configured to generate a second transmitted optical signal; a central multiplexing unit 130 configured to couple the first and second transmitted optical signals to obtain a transmitted optical signal and output it to the hollow optical fiber 102 for transmission; and a cooling unit 140 configured to cool at least one of the first light source 110, the second light source 120, and the central multiplexing unit 130. The cooling unit 140 includes: a refrigerant cavity 141 and a main control cooling pipe 142 connected to the refrigerant cavity 141. The refrigerant cavity 141 is configured to store a refrigerant medium, and the main control cooling pipe 142 is also connected to the hollow optical fiber 102.

[0030] The terminal device 200 includes: a terminal multiplexing unit 210 configured to divide the transmitted optical signal transmitted by the hollow optical fiber 102 into a first received optical signal and a second received optical signal; a terminal conversion unit 220 configured to obtain a first received electrical signal based on the first received optical signal; the terminal conversion unit is also configured to obtain a second received electrical signal based on the second received optical signal; a power supply unit 230 configured to supply power to a load device based on the first received electrical signal; the load device 240 is also configured to receive the second received electrical signal; and a terminal cooling pipe 250 connected to the hollow optical fiber 102.

[0031] The main control device 100 and the terminal device 200 are connected by hollow-core optical fiber 102. Leveraging the low transmission loss and latency of hollow-core optical fiber 102, the performance and quality of information transmission between the two devices are effectively improved. The high loss threshold of the air core enables the transmission of high-power optical signals, thereby transferring energy from the main control device 100 to the terminal device 200, supplying power to the terminal device 200 via the main control device 100. The hollow interior space of the hollow-core optical fiber 102 facilitates the transmission of a cold medium, enabling heat management for various components in both the main control device 100 and the terminal device 200. This power supply and transmission system breaks away from the traditional independent transmission logic of "energy, signal, and heat," achieving a deeply integrated physical layer "energy-signal-heat" co-transmission system. This is beneficial for realizing high-bandwidth, electromagnetic interference-resistant "zero-wiring" systems and for meeting the needs of highly integrated application scenarios such as intelligent vehicles, micro base stations, intelligent computing centers, and intelligent robots.

[0032] It should be noted that a common transmission system refers to a system that integrates multiple functions or signals within the same transmission medium (such as a single optical fiber or cable). In the technical solution of this invention, the common transmission system refers to a system that integrates energy, information, and heat within the same hollow optical fiber. Common transmission systems can improve transmission resource utilization, simplify structure, expand functionality, and reduce construction and maintenance costs.

[0033] The specific technical solutions of the common transmission system embodiment are described in detail below with reference to the accompanying drawings.

[0034] The main control device 100 is used to supply power to the terminal device 200 and control the terminal device 200.

[0035] like Figure 2 As shown, the first light source 110 is used to generate a first transmitted optical signal for energy transmission (such as...). Figure 2 (As indicated by the thick red solid line arrow).

[0036] Specifically, the first light source 110 has a relatively high power, and the generated first transmitted optical signal has a high power; the generation of the high-power first transmitted optical signal can provide a basis for the realization of energy transmission. For example, the first light source 110 can generate a first transmitted optical signal for electrical energy transmission.

[0037] In some embodiments of the present invention, the first light source 110 includes a first laser 111 and a first driver 112. The first driver 112 is used to obtain a first driving signal to drive the first laser 111 according to the electrical energy to be transmitted; the first laser 111 is used to generate a first transmitted optical signal related to energy under the drive of the first driver 112.

[0038] In some embodiments, the first laser 111 is a high-power laser, and the first transmitted optical signal it generates is an energy-transfer optical signal; the first driver 112 is a high-power laser driver. Here, a high-power laser refers to a laser used for energy transfer, characterized by high power, high efficiency, and long lifespan. The first transmitted optical signal generated by the first laser 111 matches the spectrum of the photovoltaic cell, and it typically operates in continuous or quasi-continuous mode.

[0039] The second light source 120 is used to generate a second transmitted optical signal for information transmission (such as...). Figure 2 (As indicated by the thin red solid line arrow).

[0040] Specifically, the second light source 120 has lower power, and the generated second transmitted optical signal has lower power compared to the first transmitted optical signal; the generation of the second transmitted optical signal provides the basis for information transmission. For example, the second light source 120 is capable of generating a second transmitted optical signal for information transmission.

[0041] In some embodiments of the present invention, the second light source 120 includes a second laser 121 and a second driver 122. The second driver 122 is used to obtain a second driving signal to drive the second laser 121 according to the information to be transmitted; the second laser 121 is used to generate a second transmitted optical signal related to the information under the drive of the first driver 112.

[0042] In some embodiments, the second laser 121 is a communication laser, and the generated second transmitted optical signal is a communication optical signal; the second driver 122 is a communication laser driver. Here, a communication laser refers to a laser used as an optical transmitter in an optical fiber communication or space optical communication system.

[0043] In some embodiments, the first transmitted optical signal and the second transmitted optical signal have different frequencies to avoid mutual interference. For example, the wavelength of the first transmitted optical signal is 1064 nm, and the wavelength of the second transmitted optical signal is 1550 nm.

[0044] It should be noted that in the foregoing embodiments, the main control device 100 has only one first light source 110 and one second light source 120. In other embodiments of the present invention, the main control device may have more than one of the first light source and the second light source. Specifically, the main control device includes: multiple first light sources and / or multiple second light sources. The present invention does not limit the number of first light sources and second light sources in the main control device.

[0045] It should also be noted that in some other embodiments of the present invention, the main control device includes: a plurality of first light sources to generate a plurality of first transmitting light sources; the central multiplexing unit further includes: a beam combiner configured to combine the plurality of first transmitting optical signals; the wavelength division multiplexer of the central multiplexing unit couples the second transmitting optical signal and the combined plurality of first transmitting optical signals to obtain a transmission optical signal. Setting a plurality of first light sources in the main control device to generate a plurality of first transmitting optical signals; the central multiplexing unit combining the plurality of first transmitting optical signals and coupling them with the second transmitting optical signal to obtain a transmission optical signal can effectively increase the energy transmitted by the transmission optical signal and effectively improve the energy transmission efficiency. The central multiplexing unit 130 is used to realize the coupling of the first transmitting optical signal and the second transmitting optical signal to form a transmission optical signal for transmission (e.g., ...). Figure 2 (As indicated by the thick red dashed arrow).

[0046] Specifically, the central multiplexing unit 130 is connected to the first light source 110 and the second light source 120 via optical fibers to receive the first transmitted optical signal and the second transmitted optical signal, respectively. The central multiplexing unit 130 couples the first transmitted optical signal and the second transmitted optical signal to obtain a transmitted optical signal. The central multiplexing unit 130 is also connected to the hollow-core optical fiber 102 to output the transmitted optical signal for transmission. The first light source 110 and the second light source 120 are connected to the hollow-core optical fiber 102 through the central multiplexing unit 130, and the first transmitted optical signal and the second transmitted optical signal are transmitted through the same hollow-core optical fiber 102.

[0047] In some embodiments of the present invention, the central multiplexing unit 130 includes a wavelength division multiplexer. Specifically, the central multiplexing unit 130 couples the first transmitted optical signal and the second transmitted optical signal to form a transmission optical signal through wavelength division multiplexing.

[0048] The cooling unit 140 is used to store and transport the cooling medium to achieve cooling and thermal management of various parts in the main control device.

[0049] Specifically, the cooling unit 140 includes a refrigerant chamber 141 for storing the refrigerant and a main control cooling pipe 142 connected to the refrigerant chamber 141 (e.g., Figure 2 (As shown by the midpoint line). The connection between the main control cooling pipe 142 and the refrigerant cavity 141 means that the internal spaces of the main control cooling pipe 142 and the refrigerant cavity 141 are physically connected; the connection between the main control cooling pipe 142 and the hollow internal space of the hollow optical fiber 102 means that the internal spaces of the main control cooling pipe 142 and the hollow internal space of the hollow optical fiber 102 are physically connected, thereby forming a continuous fluid channel between the refrigerant cavity 141, the main control cooling pipe 142, and the hollow internal space of the hollow optical fiber 102.

[0050] The refrigerant cavity 141 is connected to the hollow internal space of the hollow optical fiber 102 through the main control cooling pipe 141, so that the refrigerant in the refrigerant cavity 141 can flow freely in the formed fluid channel, thereby cooling each part of the main control device and transporting the heat generated by each part of the main control device to the outside.

[0051] In some embodiments of the present invention, the main cooling pipe 142 is connected to at least one capillary in the hollow optical fiber 102, and the transport of the cold medium is realized through the capillary in the hollow optical fiber 102. Realizing the transport of the cold medium through the capillary in the hollow optical fiber 102 can effectively reduce the impact of the cold medium introduction on the optical field in the hollow optical fiber, and can effectively ensure the transmission of energy, information, and heat in the hollow optical fiber.

[0052] It should be noted that, Figure 2 In some embodiments shown, the main control cooling pipe 142, indicated by dotted lines, surrounds the first light source 110, the second light source 120, and the cooling unit 140. However, this distribution surrounding the first light source 110, the second light source 120, and the cooling unit 140 is merely an example. In other embodiments of the present invention, the main control cooling pipe can be arranged in other distributions within the main control device.

[0053] In some embodiments of the present invention, the cooling unit 140 further includes a refrigerant driver 143, which is connected to the main control cooling pipeline 142 to drive the transport of the refrigerant in the main control cooling pipeline 142. The refrigerant driver 143 is used to drive the flow of the refrigerant in the main control cooling pipeline 142 to improve the cooling efficiency of various parts of the main control device. Figure 2 In some of the embodiments shown, the refrigerant driver 143 is connected between the refrigerant chamber 141 and the main control cooling line 142 to drive the refrigerant.

[0054] In some embodiments of the present invention, at least one of the first light source 110, the second light source 120, and the central multiplexing unit 130 has a device cooling pipeline, which is connected to the refrigerant cavity through a main control cooling pipeline. The device cooling pipeline (e.g.) Figure 2 The first light source 110, the second light source 120, and the central multiplexing unit 130 (shown by the black dashed lines) are connected to the refrigerant cavity through the main control cooling pipe. The internal space of the device cooling pipe is physically connected to the internal space of the refrigerant cavity 141 through the internal space of the main control cooling pipe 142, forming a continuous fluid channel. This allows the refrigerant to flow through the interior of the first light source 110, the second light source 120, and the central multiplexing unit 130 to dissipate the heat generated by the first light source 110, the second light source 120, and the central multiplexing unit 130, thereby achieving thermal management of the first light source 110, the second light source 120, and the central multiplexing unit 130.

[0055] By setting device cooling pipelines in the first light source, the second light source, and the central multiplexing unit, the distance between the cold medium and the heat source can be shortened as much as possible in the first light source, the second light source, and the central multiplexing unit, so as to improve heat transport efficiency and cooling efficiency.

[0056] In some embodiments of the present invention, the main control device further includes: a processing control unit 160, which is configured to generate a first control signal and a second control signal; a first light source 110 generates a first transmitted light signal according to the first control signal; and a second light source 110 generates a second transmitted light signal according to the second control signal.

[0057] Specifically, the processing control unit 160 is used to control the first light source 110 and the second light source 120. The processing control unit 160 generates a first control signal and a second control signal; the processing control unit 160 is connected to the first light source 110 and the second light source 120 respectively, and outputs the first control signal and the second control signal to the first light source 110 and the second light source 120 respectively.

[0058] like Figure 2 In some embodiments shown, the processing control unit 160 is connected to the first driver 112 of the first light source 110 and outputs a first control signal to the first driver 112 to generate a first transmitted light signal; the processing control unit 160 is also connected to the second driver 122 of the second light source 120 and outputs a second control signal to the second driver 122. For example, the processing control unit 160 includes a central processing controller.

[0059] In some embodiments, the processing control unit 160 is further configured to generate a third control signal; the cooling unit 140 performs cooling according to the third control signal. Specifically, the processing control unit 160 is also used to control the cooling unit's cooling of the common transmission system.

[0060] like Figure 2 In some embodiments shown, the processing control unit 160 is connected to the refrigerant driver 141 in the cooling unit 140 and generates a third control signal to the refrigerant driver 141. Under the control of the third control signal, the refrigerant driver 141 drives the transport of refrigerant in the main cooling pipeline. For example, when the temperature of the common-mode system is too high, the processing control unit 160 controls the refrigerant driver 141 to drive the refrigerant in the main cooling pipeline, or to make the refrigerant in the main cooling pipeline flow faster, in order to cool it down.

[0061] In some embodiments, the processing control unit 160 has device cooling pipelines that are connected to the refrigerant chamber 141 via a main control cooling pipeline 142. The device cooling pipelines of the processing control unit 160 (e.g.) Figure 2The internal processing control unit 160 (shown by dashed lines) is connected to the refrigerant chamber 141 via the main control cooling pipe 142. The internal space of the device cooling pipe of the processing control unit 160 is physically connected to the internal space of the refrigerant chamber 141 through the internal space of the main control cooling pipe 142, forming a continuous fluid channel. This allows the refrigerant to flow through the interior of the processing control unit 160 to dissipate the heat generated by the processing control unit 160, thereby achieving thermal management of the processing control unit 160.

[0062] In some embodiments of the present invention, in the common transmission system, the hollow optical fiber 102 is also configured to transmit a third transmitted optical signal (such as...) generated by the terminal device 200 to the main control device 100. Figure 2 (As indicated by the red dotted arrow in the middle). The main control device 100 also includes a central conversion unit 150, which is configured to receive the third transmitted optical signal transmitted by the hollow optical fiber 102 and obtain a third electrical signal based on the third transmitted optical signal. The main control device 100 can not only send a second optical signal to the terminal device 200 to control the terminal device 200, but the central conversion unit 150 in the main control device 100 can also receive the optical signal fed back by the terminal device 200. That is to say, the main control device 100 and the terminal device 200 can realize bidirectional interaction of optical signals.

[0063] In some embodiments, the central conversion unit 150 includes a photodetector. The photodetector of the central conversion unit 150 is capable of photoelectric conversion of the third transmitted optical signal, thereby generating a third electrical signal associated with the third transmitted optical signal.

[0064] In some embodiments, a central multiplexing unit 130 is connected between the hollow-core optical fiber 102 and the central conversion unit 150. The central conversion unit 150 is connected to the hollow-core optical fiber 102 via the central multiplexing unit 130 to receive a third transmitted optical signal. The central multiplexing unit 130 is also configured to receive the third transmitted optical signal transmitted by the hollow-core optical fiber 102 and transmit the third transmitted optical signal to the central conversion unit 150.

[0065] In some embodiments, the processing control unit 160 of the main control device 100 is also configured to receive a third electrical signal. Specifically, the processing control unit 160 of the main control device 100 is also connected to the central conversion unit 150 to receive the third electrical signal obtained by the central conversion unit 150.

[0066] In some embodiments of the example, the terminal device 200 has a sensing load device, and the terminal device 200 generates a third transmitted optical signal based on the sensing result of the sensing load device; the central conversion unit 150 receives the third transmitted optical signal and obtains a third electrical signal based on the third transmitted optical signal; the processing control unit 160 of the main control device 100 is also received and processed by the third electrical signal to obtain the sensing result of the sensing load device.

[0067] In some embodiments, the central switching unit 150 has device cooling lines that are connected to the refrigerant chamber 141 via a main control cooling line 142. Device cooling lines (e.g.) Figure 2 The central conversion unit 150 (shown by dashed lines) is connected to the refrigerant cavity 141 via the main control cooling pipe 142. The internal space of the device cooling pipe of the central conversion unit 150 is physically connected to the internal space of the refrigerant cavity 141 through the internal space of the main control cooling pipe 142, forming a continuous fluid channel. This allows the refrigerant to flow through the interior of the central conversion unit 150 to remove the heat generated by the central conversion unit 150, thereby achieving thermal management of the central conversion unit 150.

[0068] Continue to refer to Figure 1 and Figure 3 The shared transmission system also includes a terminal device 200. The terminal device 200 is configured to communicate with the main control device 100 of the present invention (e.g., ...). Figure 1 and Figure 2 (As shown) are connected via hollow optical fiber 102. The transmission optical signal generated by the main control device 100 is transmitted to the terminal device 200 via the hollow optical fiber 102; the terminal device 200 receives the transmission optical signal transmitted via the hollow optical fiber 102.

[0069] like Figure 3 As shown, in the terminal device 200, the terminal multiplexing unit 210 is used to multiplex the transmitted optical signals (such as those transmitted by the hollow optical fiber 102) into multiplexes. Figure 3 (As indicated by the thick red dashed arrow) is divided into the first received optical signal (such as...) Figure 3 (as indicated by the thick red solid arrow in the middle) and the second received optical signal (such as...) Figure 3 (As indicated by the thick red solid line arrow).

[0070] Specifically, the terminal multiplexing unit 210 is connected to the hollow optical fiber 102 to receive the transmitted optical signal transmitted by the hollow optical fiber 102; the terminal multiplexing unit 210 divides the transmitted optical signal into a first received optical signal and a second received optical signal.

[0071] The first received optical signal corresponds to the first transmitted optical signal, and the first received optical signal has higher power and is a power transmission optical signal; the second received optical signal corresponds to the second transmitted optical signal, and the second received optical signal has lower power and is a communication optical signal.

[0072] In some embodiments of the present invention, the terminal multiplexing unit 210 includes a wavelength division multiplexer. Specifically, the terminal multiplexing unit 210 decouples the transmitted optical signals through wavelength division multiplexing to form a first received optical signal and a second received optical signal.

[0073] The terminal conversion unit 220 is used to obtain a first received electrical signal and a second received electrical signal based on the first received optical signal and the second received optical signal, respectively.

Figure 3 (As indicated by the black dotted line arrow).

[0086] In some embodiments, the power supply unit 230 is also configured to supply power to the terminal conversion unit 220 according to the first received electrical signal. For example... Figure 2 As shown, the power manager 231 of the power supply unit 230 is connected to the terminal conversion unit 220, and supplies power to the terminal conversion unit 220 (e.g., Figure 3 (As indicated by the black solid line arrow).

[0087] In some embodiments, the power supply unit 230 further includes an energy storage element 232, which is configured to store electrical energy or release the stored electrical energy under the control of the power manager 231.

[0088] Specifically, the energy storage element 232 is an electrical component capable of storing electrical energy in the form of an electric field, magnetic field, electrochemical or mechanical means, and releasing it when needed. The energy storage element 232 can store and transfer energy during power conversion to achieve smooth voltage / current conversion, provide continuous power to the load as a main power source or backup power source in a power supply system, and absorb or release instantaneous power in a power buffer system to smooth voltage / current fluctuations.

[0089] like Figure 2 In some of the embodiments shown, the energy storage element 232 is connected to the power manager 231, and the energy storage element 232 stores and releases electrical energy under the control of the power manager 231.

[0090] The load device 240 receives the second received electrical signal and is controlled by the second received electrical signal.

[0091] Specifically, the second received electrical signal is used to control the load device 240, that is, the load device 240 performs its function under the control of the second received electrical signal. In some embodiments of the present invention, there are multiple load devices 240; the power manager 231 is connected to multiple load devices 240, and the power manager 231 supplies power to multiple load devices 240.

[0093] It should be noted that, Figure 3 In some embodiments shown, the load device 240 is a sensing load device. In other embodiments of the present invention, the load device may also be a computing load device and / or a storage load device, that is, the load device may be at least one of a sensing load device, a computing load device, and a storage load device. For example, the computing load device may be at least one of a GPU and a CPU; the storage load device may be at least one of flash memory, a high-density hard disk drive, and a phase-change memory.

[0094] Terminal cooling pipe 250 (e.g.) Figure 3 (As shown by the thick black dotted line) is used to transport the cooling medium to achieve cooling and thermal management of various parts of the terminal device 200.

[0095] Specifically, the terminal cooling pipe 250 is connected to the hollow optical fiber 102, and the internal space of the terminal cooling pipe 250 and the hollow internal space of the hollow optical fiber 102 are physically interconnected. This allows the terminal cooling pipe 250 to be connected to the refrigerant cavity 141 through the hollow optical fiber 102, forming a continuous fluid channel. The refrigerant can be transferred to the terminal device 200 through the refrigerant cavity of the cooling unit in the autonomous control device 100 via the hollow optical fiber 102, thereby realizing the cooling and thermal management of the terminal device 200.

[0096] In some embodiments of the present invention, at least one of the terminal multiplexing unit 210, load device 240, terminal conversion unit 220, and power supply unit 230 has a device cooling pipeline, which is connected to the hollow optical fiber 102 through a terminal cooling pipeline 250. The device cooling pipeline (e.g.) Figure 3 The terminal multiplexing unit 210, load device 240, terminal conversion unit 220, and power supply unit 230 (shown by the black dashed lines) are connected to the refrigerant chamber 141 (as shown in the terminal cooling pipe 250) via the terminal cooling pipe 250. Figure 2(As shown) are connected, and the internal space of the device cooling pipe is physically connected to the internal space of the refrigerant chamber 141 through the internal space of the terminal cooling pipe 250, forming a continuous fluid channel. This allows the refrigerant to flow through the interior of the terminal multiplexing unit 210, the load device 240, the terminal conversion unit 220, and the power supply unit 230 to remove the heat generated by the terminal multiplexing unit 210, the load device 240, the terminal conversion unit 220, and the power supply unit 230, thereby achieving thermal management of the terminal multiplexing unit 210, the load device 240, the terminal conversion unit 220, and the power supply unit 230.

[0097] In some embodiments of the present invention, the terminal device 200 further includes a third light source 260, which is configured to generate a third transmitted optical signal and output the third transmitted optical signal to the hollow optical fiber 102.

[0098] Specifically, the third light source 260 has lower power, and the generated third transmitted optical signal has lower power compared to the first transmitted optical signal; the generation of the third transmitted optical signal provides the basis for information transmission. For example, the third light source 260 is capable of generating a third transmitted optical signal for information transmission.

[0099] It should be noted that, as Figure 3 In some embodiments shown, the number of third light sources 260 is only one. In other embodiments of the present invention, the terminal device may have multiple third light sources. The technical solution of the present invention does not limit the number of third light sources in the terminal device.

[0100] In some embodiments of the present invention, the third light source 260 includes a third laser 261 and a third driver 262. The third driver 262 is used to obtain a third driving signal to drive the third laser 261 according to the information to be transmitted; the third laser 261 is used to generate a third transmitted optical signal related to the information under the drive of the third driver 262.

[0101] In some embodiments, the third laser 261 is a communication laser, and the generated third transmitted optical signal is a communication optical signal; the third driver 262 is a communication laser driver. Here, a communication laser refers to a laser used as an optical transmitter in an optical fiber communication or space optical communication system.

[0102] In some embodiments, the third transmitted optical signal and the first transmitted optical signal have different frequencies to avoid mutual interference. For example, the wavelength of the first transmitted optical signal is 1064 nm, and the wavelength of the second transmitted optical signal is 1550 nm.

[0103] In some embodiments, the third light source 260 has a device cooling pipeline, which is connected to the hollow optical fiber 102 via a terminal cooling pipeline 250. The device cooling pipeline of the third light source 260 (e.g.) Figure 3 The third light source 260 (shown by the black dashed line) is connected to the hollow optical fiber 102 through the terminal cooling pipe 250. The internal space of the device cooling pipe is physically connected to the hollow internal space of the hollow optical fiber 102 through the internal space of the terminal cooling pipe 250, forming a continuous fluid channel. This allows the cooling medium to flow through the interior of the third light source 260 to dissipate the heat generated by the third light source 260 and achieve thermal management of the third light source 260.

[0104] In some embodiments, the terminal multiplexing unit 210 is connected between the hollow fiber 102 and the third laser 261. The terminal multiplexing unit 210 is also configured to receive a third transmitted optical signal generated by the third light source 260 and transmit the third transmitted optical signal to the hollow fiber 102. The third laser 261 is connected to the hollow fiber 102 via the terminal multiplexing unit 210 to transmit the third transmitted optical signal.

[0105] In some embodiments of the present invention, the load device 240 is a sensing load device; the third light source 260 generates a third transmitted optical signal based on the sensing result of the sensing load device. The third transmitted optical signal is used to transmit the sensing result of the sensing load device to the main control device 100.

[0106] like Figure 2 In some embodiments shown, the load device 240 is connected to the third driver 262, which obtains the sensing result from the load device 240 and obtains a third driving signal based on the obtained sensing result to drive the third laser 261 to generate a third transmit optical signal to be output to the hollow fiber 102.

[0107] In other embodiments of the present invention, the load device may also be a computing load device; the third light source generates a third transmitted optical signal based on the calculation result of the computing load device. The third transmitted optical signal is used to transmit the calculation result of the computing load device to the main control device. In still other embodiments of the present invention, the load device may also be a storage load device; the third light source generates a third transmitted optical signal based on the read / write result of the storage load device. The third transmitted optical signal is used to transmit the read / write result of the storage load device to the main control device.

[0108] like Figures 1 to 3As shown, in the first light source 110, the first driver 112, under the control of the processing control unit 160, drives the first laser 111 to generate a first emitted light signal carrying energy; the first emitted light signal is coupled through the central multiplexing unit 130 to form a transmitted light signal and output to the hollow fiber 102 for transmission to the terminal device 200; in the terminal device 200, the terminal multiplexing unit 210 separates the first received light signal from the transmitted light signal and transmits it to the terminal conversion unit 220, where the first converter 221 completes the photoelectric conversion to obtain the first electrical signal; the first electrical signal is provided to the power manager 231 of the power supply unit 230 to supply power to the load device 240, the terminal conversion unit 220 and the third light source 260, or stored in the energy storage element 232.

[0109] Under the control of the processing control unit 160, the second driver 122 in the second light source 120 drives the second laser 121 to generate a second transmitted optical signal carrying information (i.e., communication data). The second transmitted optical signal is coupled through the central multiplexing unit 130 to form a transmission optical signal, which is output to the hollow optical fiber 102 for transmission to the terminal device 200. In the terminal device 200, the terminal multiplexing unit 210 separates the second received optical signal from the transmission optical signal and transmits it to the terminal conversion unit 220. The second converter 222 in the terminal conversion unit 220 completes the photoelectric conversion to obtain a second electrical signal. The second electrical signal is output to the load device 240 to complete the downlink interaction of information.

[0110] The third driver in the third light source 260 drives the third laser 261 to generate a third transmitted optical signal carrying information based on the information (i.e., communication data) obtained by the load device 240. The third transmitted optical signal is transmitted to the hollow optical fiber 102 via the terminal multiplexing unit 210 and sent to the main control device 100. In the main control device 100, the third transmitted optical signal is transmitted to the central conversion unit 150 via the central multiplexing unit 130. The central conversion unit 150 performs photoelectric conversion to obtain a third electrical signal, which is provided to the processing control unit 160 to complete the uplink interaction of information.

[0111] The cooling unit 140 stores a cooling medium with good heat dissipation in its refrigerant cavity 141. In the main control device 100, the cooling medium is driven by the refrigerant driver 143 and flows through the main control cooling pipe 142 and the device cooling pipe through the main control device 100 and the interior of each part of the main control device 100 to dissipate the heat generated by each device and achieve thermal management of each device. The cooling medium is transported from the main control device 100 to the terminal device 200 via the hollow optical fiber 102. In the terminal device 200, the cooling medium transported via the hollow optical fiber 102 flows through the terminal cooling pipe 250 and the device cooling pipe through the terminal device 200 and the interior of each part of the terminal device 200 to dissipate the heat generated by each device and achieve thermal management of each device.

[0112] It can be seen that by using hollow optical fiber 102, the flow of cold medium in the main control device 100 and terminal device 200 of the cotransmission system can be realized, thereby realizing the cotransmission system integrating "energy-information-heat".

[0113] It should be noted that in the foregoing embodiments, the "energy-information" co-transmission is achieved through wavelength division multiplexing in the co-transmission system. In other embodiments of the present invention, "energy-information" co-transmission can also be achieved through other methods.

The cooling unit 340 includes: a refrigerant cavity 341 and a main control cooling pipe 342 connected to the refrigerant cavity 341. The refrigerant cavity 341 is configured to store a refrigerant medium, and the main control cooling pipe 342 is also connected to a hollow optical fiber 304.

[0116] Terminal device 400 includes: The receiver conversion unit 410 is configured to receive the transmitted optical signal transmitted by the hollow optical fiber 304 and obtain a transmitted electrical signal based on the transmitted optical signal; the terminal demodulation unit 420 is configured to obtain a first received electrical signal and a second received electrical signal based on the transmitted electrical signal, wherein the power of the first received electrical signal is greater than the power of the second received electrical signal; the power supply unit 430 is configured to supply power to the load device 440 based on the first received electrical signal; the load device 440 is also configured to receive the second received electrical signal; and the terminal cooling pipe 450 is configured to cool at least one of the receiver conversion unit 410, the terminal demodulation unit 420, the power supply unit 430, and the load device 440, and the terminal cooling pipe 450 is connected to the hollow optical fiber 304.

[0117] The specific technical solutions of the common transmission system embodiment are described in detail below with reference to the accompanying drawings.

[0118] The main control device 300 is used to supply power to the terminal device 400 and control the terminal device 400.

[0119] like Figure 4 As shown, the first light source 310 is used to generate a first transmitted optical signal for energy transmission (such as...). Figure 4 (As indicated by the thick red solid line arrow).

[0120] Specifically, the first light source 310 has a relatively high power, and the generated first transmitted optical signal has a high power; the generation of the high-power first transmitted optical signal can provide a basis for the realization of energy transmission. For example, the first light source 310 can generate a first transmitted optical signal for electrical energy transmission.

[0121] In some embodiments of the present invention, the first light source 310 includes a first laser 311 and a first driver 312. The first driver 312 is used to obtain a first driving signal to drive the first laser 311 according to the electrical energy to be transmitted; the first laser 311 is used to generate a first transmitted optical signal related to energy under the drive of the first driver 312.

[0122] In some embodiments, the first laser 311 is a high-power laser, and the first transmitted optical signal it generates is an energy-transfer optical signal; the first driver 312 is a high-power laser driver. Here, a high-power laser refers to a laser used for energy transfer, characterized by high power, high efficiency, and long lifespan. The first transmitted optical signal generated by the first laser 311 matches the spectrum of the photovoltaic cell, and it typically operates in continuous or quasi-continuous mode.

[0123] The modulation unit 320 is used to modulate the first transmitted optical signal with the second transmitted signal to obtain a transmitted optical signal.

[0124] Specifically, the second transmitted signal is a communication signal for information transmission. For example, the second transmitted signal is a small signal, that is, the second transmitted signal is a signal with a small amplitude; the amplitude of the first transmitted optical signal is greater than the amplitude of the second transmitted optical signal. The first transmitted optical signal serves as the carrier, and the second transmitted signal serves as the modulation signal, which is loaded onto the first transmitted optical signal to achieve "energy-communication" co-transmission.

[0125] In some embodiments of the present invention, the second transmission signal is an electrical signal, that is, the second transmission signal is a second transmission electrical signal; the modulation unit modulates the first transmission optical signal according to the second transmission electrical signal to obtain the transmission optical signal.

[0126] Specifically, the voltage or current fluctuations of the second transmitted electrical signal are related to the information data to be transmitted. The modulation unit uses the voltage or current fluctuations of the second transmitted electrical signal to modulate parameters such as the phase, intensity, or frequency of the first transmitted optical signal, thereby obtaining the transmitted optical signal.

[0127] like Figure 4 In some embodiments shown, in the main control device 300, the first driver 312 of the first light source 310 controls the first laser 311 to generate a first transmitted optical signal (e.g., Figure 4 (Thick red solid arrow in the middle); the modulation unit 320 modulates the first transmitted optical signal according to the second transmitted optical signal to form the transmission optical signal, which is then output to the hollow optical fiber 304 for transmission (e.g., Figure 4 (As indicated by the thick red dashed arrow).

[0128] In some embodiments, the modulation unit includes a modulator. For example, the modulator may be at least one of an electro-optic modulator, an acousto-optic modulator, and a magneto-optic modulator.

[0129] The cooling unit 340 is used to store and transport the cooling medium to achieve cooling and thermal management of various parts in the main control device.

[0130] Specifically, the cooling unit 340 includes a refrigerant cavity 341 for storing the refrigerant and a main control cooling pipe 342 connected to the refrigerant cavity 341 (e.g., Figure 4 (As shown by the midpoint line). The connection between the main control cooling pipe 342 and the refrigerant cavity 341 means that the internal spaces of the main control cooling pipe 342 and the refrigerant cavity 341 are physically connected; the connection between the main control cooling pipe 342 and the hollow internal space of the hollow optical fiber 304 means that the internal spaces of the main control cooling pipe 341 and the hollow internal space of the hollow optical fiber 304 are physically connected, thereby forming a continuous fluid channel between the refrigerant cavity 341, the main control cooling pipe 342, and the hollow internal space of the hollow optical fiber 304.

[0131] The refrigerant cavity 341 is connected to the hollow internal space of the hollow optical fiber 304 through the main control cooling pipe 342, so that the refrigerant in the refrigerant cavity 341 can flow freely in the formed fluid channel, thereby cooling each part of the main control device and transporting the heat generated by each part of the main control device to the outside.

[0132] In some embodiments of the present invention, the main cooling pipe 342 is connected to at least one capillary in the hollow optical fiber 304, and the transport of the cold medium is realized through the capillary in the hollow optical fiber 304. Realizing the transport of the cold medium through the capillary in the hollow optical fiber 304 can effectively reduce the impact of the cold medium introduction on the optical field in the hollow optical fiber, and can effectively ensure the transmission of energy, information, and heat in the hollow optical fiber.

[0133] In some embodiments of the present invention, the cooling unit 340 further includes a refrigerant driver 343, which is connected to the main control cooling pipeline 342 to drive the transport of the refrigerant in the main control cooling pipeline 342. The refrigerant driver 343 is used to drive the flow of the refrigerant in the main control cooling pipeline 342 to improve the cooling efficiency of various parts of the main control device. Figure 4 In some of the embodiments shown, the refrigerant driver 343 is connected between the refrigerant chamber 341 and the main control cooling line 342 to drive the refrigerant.

[0134] In some embodiments of the present invention, at least one of the first light source 310 and the modulation unit 320 has a device cooling pipeline, which is connected to the refrigerant cavity through the main control cooling pipeline. The device cooling pipeline (e.g.) Figure 4 The first light source 310 and the modulation unit 320 (shown by the black dashed line) are connected to the refrigerant cavity through the main control cooling pipe. The internal space of the device cooling pipe is physically connected to the internal space of the refrigerant cavity 341 through the internal space of the main control cooling pipe 342, forming a continuous fluid channel. This allows the refrigerant to flow through the interior of the first light source 310 and the modulation unit 320 to remove the heat generated by the first light source 310 and the modulation unit 320, thereby achieving thermal management of the first light source 310 and the modulation unit 320.

[0135] In some embodiments of the present invention, the main control device further includes: a processing control unit 360, which is configured to generate a first control signal; and a first light source 310 generating a first transmitted light signal according to the first control signal. Furthermore, the processing control unit 360 is also configured to generate a second transmitted electrical signal.

[0136] Specifically, the processing control unit 360 is used to control the first light source 310 and the modulation unit 320. The processing control unit 360 is connected to the first light source 310 and the modulation unit 320 respectively, and outputs a first control signal and a second transmission electrical signal to the first light source 310 and the second light source 120 respectively.

[0137] like Figure 4 In some embodiments shown, the processing control unit 360 is connected to the first driver 312 of the first light source 310, and outputs a first control signal to the first driver 312 to generate a first transmitted light signal; the processing control unit 360 is connected to the modulation unit 320, and outputs a second transmitted electrical signal to the modulation unit 320. For example, the processing control unit 360 includes a central processing controller.

[0138] In some embodiments, the processing control unit 360 has device cooling pipelines that are connected to the refrigerant chamber 341 via a main control cooling pipeline 342. The device cooling pipelines of the processing control unit 360 (e.g.) Figure 2 (As shown by the dashed line in the internal processing control unit 360) is connected to the refrigerant cavity 341 through the main control cooling pipe 342. The internal space of the device cooling pipe of the processing control unit 360 is physically connected to the internal space of the refrigerant cavity 341 through the internal space of the main control cooling pipe 342, forming a continuous fluid channel, so that the refrigerant can flow through the interior of the processing control unit 360 to dissipate the heat generated by the processing control unit 360, thereby realizing the thermal management of the processing control unit 360.

[0139] In some embodiments of the present invention, in the common transmission system, the hollow optical fiber 304 is also configured to transmit a third transmitted optical signal (such as...) generated by the terminal device 400 to the main control device 300. Figure 2 (As indicated by the red dotted arrow in the middle); the main control device 300 also includes a central conversion unit 350, which is configured to receive the third transmitted optical signal transmitted by the hollow optical fiber 304 and obtain a third electrical signal based on the third transmitted optical signal. The main control device 300 can not only send a second optical signal to the terminal device 400 to control the terminal device 400 (such as...) Figure 5 As shown), the central conversion unit 350 in the main control device 300 can also receive optical signals fed back by the terminal device 400. In other words, the main control device 300 and the terminal device 400 can achieve bidirectional interaction of optical signals.

[0140] In some embodiments, the central conversion unit 350 includes a photodetector. The photodetector of the central conversion unit 350 is capable of photoelectric conversion of the third transmitted optical signal, thereby generating a third electrical signal associated with the third transmitted optical signal.

[0141] In some embodiments, the processing control unit 360 of the main control device 300 is also configured to receive a third electrical signal. Specifically, the processing control unit 360 of the main control device 300 is also connected to the central conversion unit 350 to receive the third electrical signal obtained by the central conversion unit 350.

[0142] In some embodiments of the example, the terminal device 400 has a sensing load device, and the terminal device 400 generates a third transmitted optical signal based on the sensing result of the sensing load device; the central conversion unit 350 receives the third transmitted optical signal and obtains a third electrical signal based on the third transmitted optical signal; the processing control unit 360 of the main control device 300 is also received and processed by the third electrical signal to obtain the sensing result of the sensing load device.

[0143] In some embodiments, the central switching unit 350 has device cooling lines that are connected to the refrigerant chamber 341 via a main control cooling line 342. Device cooling lines (e.g.) Figure 4The central conversion unit 350 (shown by dashed lines) is connected to the refrigerant cavity 341 via the main control cooling pipe 342. The internal space of the device cooling pipe of the central conversion unit 350 is physically connected to the internal space of the refrigerant cavity 341 through the internal space of the main control cooling pipe 342, forming a continuous fluid channel.

In other embodiments of the present invention, the receiving and conversion unit includes an on-chip optoelectronic integrated receiver chip, which includes the photodetector, to effectively reduce cost and size, and to better adapt to highly integrated intelligent systems.

[0152] The terminal demodulation unit 420 is used to demodulate the first received electrical signal and the second received electrical signal of the transmitted electrical signal group.

[0153] Specifically, the first received electrical signal corresponds to the first transmitted optical signal and is used for power transmission; the first received electrical signal has high power. The second received electrical signal corresponds to the second transmitted signal and is used for information data transmission; the second received electrical signal has low power.

[0154] like Figure 5 In some embodiments shown, the terminal demodulation unit 420 is connected to the receiving conversion unit 410 and receives the transmitted electrical signal obtained by the receiving conversion unit 410; the terminal demodulation unit 420 demodulates the transmitted electrical signal and extracts a first received electrical signal with a different power from the transmitted signal (e.g., ...). Figure 4 (As shown by the thick black dotted arrow in the middle) and the second received electrical signal. For example, the terminal demodulation unit 420 may include: a demodulator.

[0155] The power supply unit 430 is used to supply power to the load device 440 according to the first received electrical signal.

[0156] Specifically, the power supply unit 430 is connected to the terminal demodulation unit 420 and receives the first received electrical signal (such as...) obtained by the terminal demodulation unit 420. Figure 4 (As shown by the thick black dotted arrow in the middle); the power supply unit 430 is also connected to the load device 440, and the power supply unit 430 supplies power to the load device 440 according to the first received electrical signal.

[0157] In some embodiments of the present invention, the power supply unit 430 includes a power manager 431, which is configured to supply power to the load device 440 according to a first received electrical signal. The power manager 431 is an electrical device or integrated circuit used to control, regulate, monitor, and protect the power system to provide stable and reliable electrical energy to the load. The power manager 431 can realize multiple functions such as voltage conversion and regulation, power supply path switching and charging / discharging management, load power supply control, and overvoltage, overcurrent, overtemperature, and short circuit protection.

Figure 3 (As indicated by the black dotted line arrow).

[0159] In some embodiments, the power supply unit 430 is also configured to supply power to the terminal demodulation unit 420 according to the first received electrical signal. For example... Figure 5 As shown, the power manager 431 of the power supply unit 430 is connected to the terminal demodulation unit 420, and supplies power to the terminal demodulation unit 420 (e.g., Figure 3 (As indicated by the thin black solid line arrow).

[0160] In some embodiments, the power supply unit 430 further includes an energy storage element 432, which is configured to store electrical energy or release the stored electrical energy under the control of the power manager 431.

[0161] Specifically, the energy storage element 432 is an electrical component capable of storing electrical energy in the form of an electric field, magnetic field, electrochemical or mechanical means, and releasing it when needed. The energy storage element 432 can store and transfer energy during power conversion to achieve smooth voltage / current conversion, provide continuous power to the load as a main power source or backup power source in a power supply system, and absorb or release instantaneous power in a power buffer system to smooth voltage / current fluctuations.

[0163] The load device 440 receives the second received electrical signal and is controlled by the second received electrical signal.

[0164] Specifically, the second received electrical signal is used to control the load device 440, that is, the load device 440 performs its function under the control of the second received electrical signal. In some embodiments of the present invention, there are multiple load devices 440; the power manager 431 is connected to multiple load devices 440, and the power manager 431 supplies power to multiple load devices 440.

[0165] In some embodiments of the present invention, the load device 440 is a computing load device. In some embodiments, the load device is a GPU. Figure 5 In some of the embodiments shown, the load device 440 can be a computing load device such as a first GPU, a second GPU, a third GPU, and a fourth GPU.

[0166] Terminal cooling pipe 450 (e.g.) Figure 5 (As shown by the thick black dotted line) is used to transport the cooling medium to achieve cooling and thermal management of various parts of the terminal device 400.

[0167] Specifically, the terminal cooling pipe 450 is connected to the hollow optical fiber 304, and the internal space of the terminal cooling pipe 450 and the hollow internal space of the hollow optical fiber 304 are physically interconnected. This allows the terminal cooling pipe 450 to be connected to the refrigerant cavity 341 through the hollow optical fiber 304, forming a continuous fluid channel. The refrigerant can be transferred to the terminal device 400 through the refrigerant cavity of the cooling unit in the autonomous control device 300 via the hollow optical fiber 304, thereby realizing the cooling and thermal management of the terminal device 400.

[0168] In some embodiments of the present invention, at least one of the receiving conversion unit 410, the load device 440, the terminal demodulation unit 420, and the power supply unit 430 has a device cooling pipeline, which is connected to the hollow optical fiber through a terminal cooling pipeline. The device cooling pipeline (e.g.) Figure 5 The receiver / conversion unit 410, load device 440, terminal demodulation unit 420, and power supply unit 430 (shown by the black dashed lines) are connected to the refrigerant chamber 341 via the terminal cooling pipe 450 (as shown in the black dashed lines in the diagram). Figure 4 (As shown) are connected, and the internal space of the device cooling pipe is physically connected to the internal space of the refrigerant chamber 341 through the internal space of the terminal cooling pipe 450, forming a continuous fluid channel. This allows the refrigerant to flow through the interior of the receiving conversion unit 410, the load device 440, the terminal demodulation unit 420, and the power supply unit 430, so as to remove the heat generated by the receiving conversion unit 410, the load device 440, the terminal demodulation unit 420, and the power supply unit 430, thereby realizing thermal management of the receiving conversion unit 410, the load device 440, the terminal demodulation unit 420, and the power supply unit 430.

[0169] In some embodiments of the present invention, the terminal device 400 further includes a third light source 460, which is configured to generate a third transmitted optical signal and output the third transmitted optical signal to the hollow optical fiber 304.

[0170] Specifically, the third light source 460 has lower power, and the generated third transmitted optical signal has lower power compared to the first transmitted optical signal; the generation of the third transmitted optical signal provides the basis for information transmission. For example, the third light source 460 is capable of generating a third transmitted optical signal for information transmission.

[0171] It should be noted that, as Figure 3 In some embodiments shown, the number of third light sources 460 is only one. In other embodiments of the present invention, the terminal device may have multiple third light sources. The technical solution of the present invention does not limit the number of third light sources in the terminal device.

[0172] In some embodiments of the present invention, the third light source 460 includes a third laser 461 and a third driver 462.

[0173] In some embodiments, the third laser 461 is a communication laser, and the generated third transmitted optical signal is a communication optical signal; the third driver 462 is a communication laser driver. Here, a communication laser refers to a laser used as an optical transmitter in an optical fiber communication or space optical communication system.

[0174] In some embodiments, the third transmitted optical signal and the first transmitted optical signal have different frequencies to avoid mutual interference. For example, the wavelength of the first transmitted optical signal is 1064 nm, and the wavelength of the second transmitted optical signal is 1550 nm.

[0175] In some embodiments, the third light source 460 has a device cooling pipeline, which is connected to the hollow optical fiber 304 via a terminal cooling pipeline 450. The device cooling pipeline of the third light source 461 (e.g.) Figure 3 The third light source 461 (shown by the black dashed line) is connected to the hollow optical fiber 304 through the terminal cooling pipe 450. The internal space of the device cooling pipe is physically connected to the hollow internal space of the hollow optical fiber 304 through the internal space of the terminal cooling pipe 450, forming a continuous fluid channel. This allows the cooling medium to flow through the interior of the third light source 461 to remove the heat generated by the third light source 461 and achieve thermal management of the third light source 461.

[0176] In some embodiments of the present invention, the load device 440 is a computing load device; the third light source 460 generates a third transmitted optical signal based on the calculation result of the computing load device. The third transmitted optical signal is used to transmit the calculation result of the computing load device to the main control device 300.

[0177] like Figure 5 In some of the embodiments shown, the load device 440 is connected to the third driver 462, which obtains the sensing result from the load device 440 and obtains a third driving signal based on the obtained sensing result to drive the third laser 461 to generate a third transmitted optical signal to be output to the hollow fiber 304.

[0178] It should also be noted that, Figure 5 In some embodiments, the second transmission signal is a second transmission electrical signal, and the modulation unit modulates the first transmission optical signal according to the second transmission electrical signal to obtain the transmission optical signal. In other embodiments of the present invention, the second transmission signal may also be an optical signal, that is, the second transmission signal is a second transmission optical signal; the modulation unit modulates the first transmission optical signal according to the second transmission optical signal to obtain the transmission optical signal.

[0180] like Figure 6 In some embodiments shown, in the main control device 500, the processing control unit 560 generates a first control signal based on the energy to be transmitted and a second control signal based on the data information to be transmitted; the first driver 512 of the first light source 510 drives the first laser 511 to generate a first transmitted optical signal according to the first control signal; the second driver 522 of the second light source 520 drives the second laser 521 to generate a second transmitted optical signal according to the second control signal; the modulation unit 530 modulates the first transmitted optical signal according to the second transmitted optical signal to obtain a transmitted optical signal and outputs it to the hollow optical fiber 509 for transmission. For example, the modulation unit 530 may include an all-optical modulator.

[0181] In some embodiments, the second light source 520 has a device cooling pipeline, which is connected to the refrigerant cavity 541 in the cooling unit 540 via the main control cooling pipeline 542. The device cooling pipeline of the second light source 520 (e.g.) Figure 6(As shown by the black dashed line in the inner second light source 520) is connected to the refrigerant cavity 541 through the main control cooling pipe 542. The internal space of the device cooling pipe is physically connected to the internal space of the refrigerant cavity 541 through the internal space of the main control cooling pipe 542, forming a continuous fluid channel. This allows the refrigerant to flow through the interior of the second light source 520 under the drive of the refrigerant driver 543, so as to remove the heat generated by the second light source 520 and realize the thermal management of the second light source 520.

[0182] It should be noted that the specific technical solutions for at least one of the terminal device 400 and its power supply unit 430, load device 440 and third light source 460 can also refer to the foregoing. Figures 1 to 3 The example shown.

[0183] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
