Description

Technical Field

[0001] This application relates to the field of computing devices, and more particularly to a signal transmission system. Background Technology

[0002] With the development of industrial automation and edge computing, the demand for industrial personal computers (IPCs) and edge devices is increasing. These IPCs or edge devices are typically installed in complex industrial environments, such as manufacturing workshops, remote sites, or areas with high electromagnetic interference.

[0003] In related technologies, in complex industrial environments, it is often necessary to install some cables to power these IPCs or edge devices, and to install other cables to transmit communication data between these IPCs or edge devices and other devices.

[0004] However, in complex industrial environments with limited space or long transmission distances, the cabling of these IPCs or edge devices is quite complex, resulting in high installation and maintenance costs. Furthermore, there may be electromagnetic interference (EMI) issues between cables used for data transmission and cables used for power supply, making the data transmission process susceptible to electromagnetic interference in the environment, which in turn leads to poor data transmission stability. Utility Model Content

[0005] This application provides a signal transmission system for saving installation and maintenance costs of cabling for IPCs or edge devices in complex industrial environments, and for improving the data transmission stability of these IPCs or edge devices.

[0006] In a first aspect, embodiments of this application provide a signal transmission system, comprising: a first optoelectronic component, an optical cable, and a second optoelectronic component, wherein...

[0007] The first optoelectronic component is connected to the second optoelectronic component via an optical cable. The first optoelectronic component is also used to connect to the first device and the power supply. The second optoelectronic component is also used to connect to the second device.

[0008] The first optoelectronic component is used to convert the communication data and power input voltage of the first device into optical signals, and transmit the optical signals to the second optoelectronic component through an optical cable;

[0009] The second optoelectronic component is used to convert optical signals into data processing signals and the operating voltage of the second device, send data processing signals to the second device, and supply power to the second device based on the operating voltage.

[0010] In the above technical solution, the transmission process of electrical signals can be converted into the transmission process of optical signals through the cooperation of the first and second optoelectronic components. Communication data between the first and second devices, as well as power supply to the second device, are transmitted synchronously via optical fiber. This signal transmission system achieves high-speed and stable optical signal transmission through optical fiber, resulting in higher transmission speed and lower signal loss, making signal transmission more efficient and thus improving data transmission speed. Furthermore, this signal transmission system eliminates the need for separate cabling for data transmission and power transmission between the first and second devices, simplifying the system wiring for the second device, improving the stability of data transmission and the anti-interference capability during power supply, enhancing power supply efficiency and transmission distance, and increasing the flexibility and scalability of power supply and data transmission for the second device. Therefore, this signal transmission system is applicable to various power supply and data transmission scenarios.

[0011] In one possible implementation, the signal transmission system further includes a controller, which establishes communication connections with the first optoelectronic component and the second optoelectronic component, respectively.

[0012] The controller is used to acquire the service requirements of the second device, and to adjust the transmission process of the first optoelectronic component and the second optoelectronic component to the communication data and input voltage based on the communication data, input voltage and service requirements.

[0013] In the above technical solution, the controller can dynamically adjust the transmission power and bandwidth resources of the optical signal transmitted by the first optoelectronic component through the optical cable according to the real-time service needs of the second device. This makes the power supply and data transmission process for the second device more flexible and accurate, enabling intelligent management of power transmission and data transmission in the signal transmission system. For example, when data transmission demand is high, the controller can prioritize allocating more bandwidth for communication data transmission; when power supply demand increases, the controller can appropriately increase the bandwidth resources occupied by power transmission.

[0014] In one possible implementation, the first optoelectronic component includes a data input component, a power input component, and a laser emitter, wherein,

[0015] The data input component is connected between the first end of the laser emitter and the first device. The data input component is used to receive communication data sent by the first device and send communication data to the controller.

[0016] The power input component is connected between the first end of the laser emitter and the power supply. The power input component is used to obtain the input voltage of the power supply and send the input voltage to the controller.

[0017] The second end of the laser emitter is connected to an optical cable. The laser emitter is used to generate optical signals under the control of the controller, and to send optical signals to the second optoelectronic component through the optical cable.

[0018] In the above technical solution, by decoupling the first optoelectronic component into a data input component, a power input component, and a laser emitter, the data input process, power input process, and photoelectric conversion process of the first optoelectronic component can be processed independently, avoiding mutual interference between the processes and helping to ensure the stability of the second optoelectronic component's operation.

[0019] In one possible implementation, the first optoelectronic component further includes a power regulator connected to the laser emitter and also for connection to a controller.

[0020] The controller is used to determine the laser power and wavelength information based on communication data, input voltage and service requirements, and to send the laser power to the power regulator and the wavelength information to the laser transmitter.

[0021] The power regulator is used to adjust the transmission power of the optical signal sent from the laser transmitter to the optical cable according to the laser power.

[0022] The laser emitter is used to generate corresponding optical signals based on wavelength information, and to transmit optical signals to the second optoelectronic component via optical cable based on transmission power.

[0023] In the above technical solution, by adding a power regulator to the first optoelectronic component, the transmission power and wavelength information of the optical signal transmitted by the first optoelectronic component through the optical cable can be dynamically adjusted according to the real-time service requirements of the equipment, making the power supply and data transmission process for the second equipment more flexible and accurate.

[0024] In one possible implementation, the first optoelectronic component further includes a detector, which is connected to both the power regulator and the laser emitter.

[0025] The detector is used to acquire the operating data of the laser emitter and send the operating data to the power regulator;

[0026] The power regulator is used to determine the operating status of the laser transmitter based on operating data, and to reduce the transmission power of the laser transmitter or shut down the laser transmitter if the operating status of the laser transmitter is abnormal.

[0027] In the above technical solution, by adding a detector to the first optoelectronic component, the working status of the laser transmitter can be monitored in real time. This allows for timely reduction of the transmission power of the laser transmitter or shutdown of the laser transmitter when the working status is abnormal, thus avoiding accidents and ensuring the safety of laser transmission.

[0028] In one possible implementation, the second optoelectronic component includes a light wave splitter, a photoelectric converter, and a data processor, wherein,

[0029] The first end of the optical wave splitter is connected to the optical cable, and the second end of the optical wave splitter is connected to the photoelectric converter and the data processor respectively. The photoelectric converter and the data processor are also used to connect to the second device.

[0030] The optical wave splitter is used to split the optical signal transmitted by the optical cable into a data optical signal and a power supply optical signal, and send the power supply optical signal to the photoelectric converter and the data optical signal to the data processor.

[0031] The photoelectric converter is used to convert the power supply optical signal into the operating voltage and power a second device based on the operating voltage;

[0032] The data processor is used to convert the data optical signal into a data processing signal corresponding to the second device, and to send the data processing signal to the second device.

[0033] In the above technical solution, the second optoelectronic component is decoupled into a light wave separator, a photoelectric converter, and a data processor, so as to realize the independent processing of the light wave separation process, photoelectric conversion process, and data processing process of the second optoelectronic component, avoid mutual interference between the processes, and help ensure the stability of the operation of the second optoelectronic component.

[0034] In one possible implementation, the second optoelectronic component further includes an energy storage component connected between the optoelectronic converter and the second device;

[0035] The energy storage component is used to store the electrical energy output by the photoelectric converter and to power a second device based on the operating voltage. The electrical energy is obtained by the photoelectric converter from the conversion of the power supply optical signal.

[0036] In the above technical solution, by setting up an energy storage component, electrical energy can be stored, allowing for timely allocation of power to the second device based on its real-time power demand. For example, when the second device's power demand is low, the energy storage component can store excess electrical energy; when the second device's power demand increases, some of the stored electrical energy can be used to power the second device, which improves the flexibility and stability of the signal transmission system's power supply and enables efficient utilization of electrical energy.

[0037] In one possible implementation, the data processor includes a communication interface for connecting to a second device, and the communication interface supports multiple communication protocols.

[0038] The data processor is used to send data processing signals to a second device via a communication interface.

[0039] In the above technical solution, by setting a communication interface in the data processor, it is easy for the data processor to connect and integrate with external devices (e.g., a second device), so that the data processor can support multiple communication methods (such as Ethernet, serial communication, etc.) based on the communication interface, thereby making the data processor compatible with different types of devices and improving the flexibility of the data processor.

[0040] In one possible implementation, the laser emitter includes a first laser emitter and a second laser emitter, and the optical wave splitter includes a first optical wave splitter and a second optical wave splitter, wherein:

[0041] The first laser emitter is connected to the first optical wave splitter via an optical cable. The first laser emitter is also connected to the data input component, and the first optical wave splitter is also connected to the data processor.

[0042] The second laser emitter is connected to the second optical wave splitter via an optical cable. The second laser emitter is also connected to the power input component, and the second optical wave splitter is also connected to the photoelectric converter.

[0043] In the above technical solution, a first laser emitter for data transmission and a second laser emitter for power transmission can be separately arranged in the first optoelectronic component, and a first optical wave splitter for data transmission and a second optical wave splitter for power transmission can be separately arranged in the second optoelectronic component. This allows the optical signal conversion processes for data transmission and power transmission to be arranged independently, thereby avoiding mutual interference between the optical signal conversion processes for data transmission and power transmission, improving the stability of data transmission, and ensuring the security of power transmission.

[0044] In one possible implementation, the optical cable includes a first optical cable and a second optical cable, wherein...

[0045] The first optical cable is connected between the first laser transmitter and the first optical wave splitter;

[0046] The second optical cable connects the second laser transmitter and the second optical wave splitter.

[0047] In the above technical solution, a first optical cable for data transmission and a second optical cable for power transmission can be laid separately, thereby avoiding mutual interference between the optical signals for data transmission and the optical signals for power transmission, improving the stability of data transmission, and further ensuring the security of power transmission.

[0048] The signal transmission system provided in this application includes a first optoelectronic component, an optical cable, and a second optoelectronic component. The first optoelectronic component is connected to the second optoelectronic component via the optical cable. The first optoelectronic component is also used to connect to a first device and a power supply, and the second optoelectronic component is also used to connect to a second device. This signal transmission system, through the cooperation of the first and second optoelectronic components, converts the transmission process of an electrical signal into the transmission process of an optical signal, and synchronously transmits communication data between the first and second devices and the power supplied to the second device via the optical cable. This signal transmission system eliminates the need for separate cabling for data transmission and power transmission between the first and second devices, simplifying the system wiring of the second device and saving installation and maintenance costs for IPCs or edge devices in complex industrial environments. Furthermore, this signal transmission system uses optical cables for high-speed and stable optical signal transmission, resulting in higher transmission speeds and lower signal loss. It enables contactless laser power supply, eliminating potential safety hazards and electromagnetic interference caused by cables, and ensuring the stability of data transmission and the reliability of power supply for the second device (e.g., an IPC or edge device) in complex industrial environments.

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0060] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0061] To facilitate understanding of the signal transmission system provided in the embodiments of this application, the following will be combined with... Figure 1 The application scenarios involved in the embodiments of this application will be described.

[0062] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 1 In industrial automation or edge computing scenarios, a first device, a second device, and a power supply can be deployed. The first device can interact with the second device through multiple input and output cables, and the power supply can provide power to the second device through the cables.

[0063] The second device can be deployed in a complex industrial environment, while the first device and power supply can be deployed outside of that complex industrial environment. For example, the complex industrial environment can be a manufacturing workshop, a remote site, or a high electromagnetic interference area. The second device can be an IPC or an edge device, and the first device can be a management device or a control device. These management devices or control devices can communicate with the IPC or edge device.

[0064] The power supply can provide power to the second device based on power supply technology, which can include wired power supply technology and wireless power supply technology. The two technologies will be described in detail below.

[0065] Power supply technology 1: Wired power supply technology

[0066] Wired power supply technology is a technology that allows a power source to supply power to a device through a physically connected power line; for example, a power source can supply power to a device through a cable.

[0067] In space-constrained scenarios, the number of cables increases with the number of secondary devices within the space, increasing the complexity of cable routing and making installation and maintenance more labor-intensive and difficult. Furthermore, if the secondary devices simultaneously transmit data via cables, electromagnetic interference (EMI) may exist between the cables used for data transmission and those used for power supply in certain environments (e.g., high electromagnetic noise environments). This makes data transmission susceptible to environmental electromagnetic interference, leading to instability or even transmission failure.

[0068] Power supply technology 2: Wireless power supply technology

[0069] Wireless power supply (WPS) technology allows devices to be powered without relying on physically connected power lines. For example, power can be supplied via inductive power or microwave transmission. While WPS has been applied in some fields, limitations in power distance, power density, and efficiency make it difficult to meet the power supply needs of high-power IPCs or long-distance edge devices. Furthermore, in high-interference environments, the stability and security of WPS power supply are difficult to guarantee.

[0070] IPCs or edge devices are typically deployed in environments with high security requirements, such as petrochemical plants, power stations, or around high-voltage equipment. These environments place stringent requirements on the reliability and security of power supply and data transmission for IPCs or edge devices, making it difficult for cable-powered and wireless power supply technologies to meet these requirements.

[0071] In some embodiments, power supply to the IPC can be implemented in the following ways:

[0072] Method 1: DC Power Supply

[0073] The IPC can be powered by a DC power supply, for example, with standard voltages of 12V, 24V, or 48V. These standard voltages can be provided by an external power adapter or power module, connected directly to the IPC's power input interface via a dedicated cable. DC power supply systems are relatively simple, provide stable voltage, and are suitable for various industrial environments, such as battery-powered applications. However, DC power supply cabling is complex, easily affected by environmental physical limitations, and can lead to voltage drops and efficiency reductions over long distances, impacting the normal operation of the IPC.

[0074] Method 2: AC Power Supply

[0075] Some IPCs (Internet Protocol Cells) can support direct AC power supply; for example, the standard voltage of the DC power supply can be 110V or 220V. In this scenario, the IPC can have an internal power conversion module that converts AC power to DC power to supply the components within the IPC. The advantage of AC power supply is that the IPC can be directly connected to mains power, making it suitable for applications requiring higher power and applicable to areas with reliable power supply. However, the stability of AC power supply is affected by fluctuations in the external power grid. In some industrial scenarios, the stability of AC power supply may fluctuate due to power noise or voltage instability. Furthermore, AC cable wiring is more complex and poses safety hazards.

[0076] Method 3: Power over Ethernet (PoE)

[0077] Some low-power IPCs can be powered via PoE technology, which provides power while transmitting data over a standard Ethernet cable. This technology is typically used for powering lightweight devices and edge nodes. PoE simplifies cabling, enabling data and power transmission through a single Ethernet cable, making it particularly suitable for space-constrained environments. However, PoE has limited power delivery distance and relatively low power output, making it difficult to adapt to devices with varying power consumption requirements. For example, the maximum power provided by PoE is only 25W or 60W; when the IPC's power consumption is high, PoE struggles to support the power needs of high-power IPCs.

[0078] This application provides a signal transmission system that includes a first optoelectronic component, an optical cable, and a second optoelectronic component. The first and second optoelectronic components can cooperate to convert the transmission of electrical signals into the transmission of optical signals. This eliminates the need for multiple cables for data transmission and power transmission between the first and second devices, allowing for the synchronous transmission of communication data and power to the second device via the optical cable. Through this design, the signal transmission system offers the following advantages:

[0079] Simplified system cabling: In space-constrained or remotely deployed scenarios, the second device (e.g., IPC or edge device) does not need to be laid out with complex power and data transmission lines. Power and data can be transmitted synchronously with only a small number of optical cables. This helps to reduce the number of cables and physical connections, reduce cabling costs and complexity, and make the cabling of the second device simpler, which helps to reduce the installation and maintenance costs of cabling.

[0080] Improving the system's anti-interference capability and security: In some environments (e.g., high electromagnetic noise environments), optical cables are not sensitive to electromagnetic interference. In these environments, replacing multiple cables used for data transmission and power transmission between the first and second devices with optical cables can avoid the impact of electromagnetic interference on data transmission, reduce system interruptions caused by cable faults, improve the stability of data transmission and the anti-interference capability during power supply, and also help avoid safety hazards caused by cable power transmission in some high-power power supply scenarios, thereby improving power supply safety and reliability.

[0081] Improving power supply efficiency and transmission distance: By converting the transmission process of electrical signals into the transmission process of optical signals, it is beneficial to ensure the stability of signal transmission. Furthermore, in some remote or distributed deployment scenarios, by replacing multiple cables with optical cables, long-distance signal transmission can be achieved, while avoiding the problems of voltage drop and efficiency reduction when transmitting power over long distances, which is beneficial to improving power supply efficiency and transmission distance.

[0082] Enhance system flexibility and scalability: The operating voltage supplied to the second device can be adjusted in a timely manner according to the power consumption requirements of the second device (e.g., IPC or edge device) in different scenarios, making the power supply process of the second device more flexible. It can be applied to a variety of power supply scenarios and can also meet the power supply requirements of second devices with different power consumption.

[0083] Meeting the needs of high-safety industrial environments: In some industrial environments with strict safety requirements, such as petrochemical plants or high-voltage areas, contactless laser power supply can be achieved by eliminating multiple cables for data transmission and power transmission between the first and second devices. This helps to eliminate potential safety hazards caused by cables, thereby meeting the high safety requirements of the second devices (e.g., IPCs or edge devices) in these industrial environments and ensuring the reliability and stability of the second devices' operation.

[0084] To facilitate understanding, the following will be combined with... Figures 2-8 The structure of the signal transmission system shown in the embodiments of this application will be described in detail through specific examples. It should be noted that the following embodiments may exist independently or in combination with each other, and the same or similar content will not be described again in different embodiments.

[0085] Figure 2 For one of the structural schematic diagrams of the signal transmission system provided in the embodiments of this application, please refer to [link / reference]. Figure 2 The signal transmission system 10 includes: a first optoelectronic component 101, an optical cable 102, and a second optoelectronic component 103.

[0086] First, the connection relationships between the components are explained in detail.

[0087] The first optoelectronic component 101 is connected to the second optoelectronic component 103 via an optical cable 102. The first optoelectronic component 101 is also used to connect to the first device 20 and the power supply 30, and the second optoelectronic component 103 is also used to connect to the second device 40.

[0088] like Figure 2 As shown, the first optoelectronic component 101, the first device 20, and the power supply 30 can be deployed at the first end, for example, outside a complex industrial environment; the second optoelectronic component 103 and the second device 40 can be deployed at the second end, for example, inside a complex industrial environment. It is understood that the first end and the second end are usually far apart, resulting in a relatively long optical cable 102, for example, the length of the optical cable 102 can be greater than 100 meters.

[0089] Secondly, the purpose of each component is explained in detail.

[0090] (1) First optoelectronic component 101

[0091] The first optoelectronic component 101 can be used to convert the communication data and power input voltage of the first device into optical signals, and transmit the optical signals to the second optoelectronic component through an optical cable.

[0092] It should be noted that the specific process by which the first optoelectronic component converts communication data and input voltage into optical signals will be explained later. Figures 4-8 Detailed explanation is provided in the embodiments.

[0093] (2) Optical cable 102

[0094] Optical cable 102 is a channel for optical signal transmission, which may be composed of high-quality optical fiber. In some examples, "optical cable" may also be referred to as "optical fiber".

[0095] Optical cable 102 can be used for optical signal transmission between the first optoelectronic component 101 and the second optoelectronic component 103. Optical cable 102 can use wavelength division multiplexing (WDM) technology to integrate optical signals of different wavelengths together for transmission, making the transmission of optical signals more efficient and improving the resource utilization of optical cable.

[0096] In some embodiments, during long-distance transmission, signal amplification technology or the like can be used to enhance the signal strength transmitted by the optical cable 102, so as to achieve optimized signal processing, so that the optical cable 102 can still maintain signal stability during long-distance transmission, avoiding data loss or reduced power transmission efficiency.

[0097] (3) Second optoelectronic component 103

[0098] The second optoelectronic component 103 is used to convert optical signals into data processing signals and the operating voltage of the second device, send data processing signals to the second device, and supply power to the second device based on the operating voltage.

[0099] The data processing signal is used to transmit communication data sent by the first device.

[0100] It should be noted that the specific process by which the second optoelectronic component converts the optical signal into a data processing signal and the operating voltage of the second device will be explained later. Figures 4-8 Detailed explanation is provided in the embodiments.

[0101] In this signal transmission system, the first and second optoelectronic components can cooperate to convert the transmission of electrical signals into the transmission of optical signals. Communication data between the first and second devices, as well as power supply to the second device, are transmitted synchronously via optical fiber. This signal transmission system achieves high-speed and stable optical signal transmission through optical fiber, resulting in higher transmission speeds and lower signal loss, making signal transmission more efficient and thus improving data transmission speed. Furthermore, this system eliminates the need for separate cabling for data transmission and power transmission between the first and second devices, simplifying the system wiring for the second device, improving the stability of data transmission and the anti-interference capability during power supply, enhancing power supply efficiency and transmission distance, and increasing the flexibility and scalability of power supply and data transmission for the second device. Therefore, this signal transmission system is applicable to various power supply and data transmission scenarios.

[0102] In some embodiments, such as Figure 3 As shown, the signal transmission system 10 may also include a controller. Figure 3 For the second schematic diagram of the signal transmission system provided in the embodiments of this application, please refer to [link / reference]. Figure 3 ,exist Figure 2 Based on the structure of the signal transmission system 10 shown, the signal transmission system 10 further includes a controller 104, which can establish communication connections with the first optoelectronic component 101 and the second optoelectronic component 103 respectively. Figure 3 As shown, the controller 104 can be installed together with the first optoelectronic component 101 at the first end.

[0103] The controller 104 can be used to acquire the service requirements of the second device 40, and to adjust the transmission process of the first optoelectronic component and the second optoelectronic component to the communication data and input voltage according to the communication data, input voltage and service requirements.

[0104] In some embodiments, business requirements may include power supply requirements and data transmission requirements. The power supply requirements may include, but are not limited to, the operating voltage and / or input power currently required by the second device, and the data transmission requirements may include, but are not limited to, the maximum amount of communication data that the second device can currently process or the bandwidth resources reserved by the second device for communication data processing.

[0105] In this signal transmission system, the controller 104 can dynamically adjust the transmission power and bandwidth resources of the optical signal transmitted by the first optoelectronic component 101 through the optical cable 102 according to the real-time service requirements of the second device. This makes the power supply and data transmission process for the second device more flexible and accurate, enabling intelligent management of power transmission and data transmission in the signal transmission system. For example, when data transmission demand is high, the controller 104 can prioritize allocating more bandwidth for communication data transmission; when power supply demand increases, the controller 104 can appropriately increase the bandwidth resources occupied by power transmission.

[0106] In some embodiments, the bandwidth resource is positively correlated with the wavelength of the optical signal transmitted through the optical cable; the more wavelengths corresponding to the optical signal, the greater the bandwidth resource; conversely, the fewer wavelengths corresponding to the optical signal, the less bandwidth resource. When data transmission demand is high, the controller 104 can prioritize allocating more wavelengths of optical signal for communication data transmission to increase the bandwidth resource occupied by communication data transmission. When power supply demand increases, the controller 104 can allocate more wavelengths of optical signal for power transmission to increase the bandwidth resource occupied by power transmission.

[0107] Figure 4 This is the third schematic diagram of the signal transmission system provided in the embodiments of this application. Please refer to [the diagram]. Figure 4 ,exist Figure 3 Based on the structure of the signal transmission system 10 shown, the first optoelectronic component 101 may further include a data input component 1011, a power input component 1012 and a laser emitter 1013, and the second optoelectronic component 103 may further include a light wave splitter 1031, a photoelectric converter 1032 and a data processor 1033.

[0108] First, the connection relationships between the components are explained in detail.

[0109] The data input component 1011 is connected between the first end of the laser emitter 1013 and the first device 20, the power input component 1012 is connected between the first end of the laser emitter 1013 and the power supply 30, and the second end of the laser emitter 1013 is connected to the optical cable 102.

[0110] The first end of the optical wave splitter 1031 is connected to the optical cable, and the second end of the optical wave splitter 1031 is connected to the photoelectric converter 1032 and the data processor 1033 respectively. The photoelectric converter 1032 and the data processor 1033 are also used to connect to the second device 40 respectively.

[0111] Secondly, the purpose of each component will be explained one by one.

[0112] (1) Data input component 1011

[0113] The data input component 1011 can be used to receive communication data sent by the first device 20 and send communication data to the controller 104.

[0114] Optionally, the data input component may include a data interface (e.g., an input / output interface), through which the first device 20 can send communication data to the data input component. The number of data interfaces can be one or more, and each data interface can support one or more communication protocols, enabling the data input component to be compatible with different types of first devices and improving its flexibility.

[0132] In some embodiments, the photoelectric converter may use photoelectric conversion technology to convert the power supply optical signal into the operating voltage of the second device 40, and power the second device 40 based on the operating voltage.

[0133] This signal transmission system, by incorporating a high-efficiency photoelectric converter 1032 in the second optoelectronic component, can efficiently convert transmitted laser energy into DC power to supply the second device. This results in the following advantages: higher power supply efficiency: efficient photoelectric conversion reduces energy loss and improves the energy utilization efficiency of the signal transmission system when powering the second device; support for long-distance power supply: optical cables maintain efficient energy conversion during long-distance transmission, enabling the signal transmission system to power remotely deployed industrial equipment, thus expanding the range of power supply scenarios; reduced maintenance costs: it reduces voltage drop and power loss associated with traditional power transmission, which helps reduce the frequency of equipment maintenance and replacement, thereby lowering maintenance costs.

[0140] In this signal transmission system, by setting a communication interface in the data processor, it is easy for the data processor to connect and integrate with external devices (e.g., a second device). This allows the data processor to support multiple communication methods (such as Ethernet, serial communication, etc.) based on the communication interface, thereby making the data processor compatible with different types of devices and improving the flexibility of the data processor.

Figure 5 ,exist Figure 4 Based on the structure of the signal transmission system 10 shown, the first optoelectronic component 101 may further include a power regulator 1014 and a detector 1015.

[0144] First, the connection relationships between the power regulator 1014 and the detector 1015 and other components in the signal transmission system 10 will be explained.

[0145] The power regulator 1014 is connected to the laser emitter 1013, and the power regulator 1014 is also used to connect to the controller 104.

[0146] The detector 1015 can be connected to the power regulator 1014 and the laser emitter 1013 respectively.

[0147] Secondly, the purpose of each component in the signal transmission system 10 will be explained in detail.

[0148] (1) Controller 104

[0149] The controller 104 can be used to acquire the service requirements of the second device 40, the communication data sent by the data input component 1011, and the input voltage of the power supply 30 sent by the power input component 1012; and to determine the laser power and wavelength information based on the communication data, the input voltage and the service requirements, and send the laser power to the power regulator 1014 and the wavelength information to the laser emitter 1013.

[0150] (2) Power Regulator 1014

[0151] The power regulator 1014 can be used to adjust the transmission power of the optical signal sent from the laser transmitter 1013 to the optical cable according to the laser power.

[0152] Understandably, the power regulator can communicate with the controller in real time to receive the laser power sent by the controller and adjust the transmission power of the optical signal sent by the laser transmitter to the optical cable in a timely manner, so as to ensure that the optical signal can meet the power supply and data transmission requirements of the second device.

[0153] In some embodiments, the power regulator 1014 may also acquire the service requirements of the second device 40, the communication data sent by the data input component 1011, and the input voltage of the power supply 30 sent by the power input component 1012; and determine the laser power and wavelength information based on the communication data, the input voltage, and the service requirements, and send the laser power and wavelength information to the laser transmitter 1013.

[0154] In some embodiments, the power regulator 1014 can also be used to acquire operating data of the laser transmitter 1013; determine the operating state of the laser transmitter based on the operating data; and reduce the transmission power of the laser transmitter or turn off the laser transmitter if the operating state of the laser transmitter is abnormal.

[0155] The operational data may include: whether there are obstacles in the optical signal transmission path, the temperature of the laser transmitter and optical cable during optical signal transmission, the operating status of the laser transmitter, the transmission power of the optical signal emitted by the laser transmitter, and the wavelength information of the optical signal emitted by the laser transmitter.

[0156] Understandably, if there are obstacles in the optical signal transmission path, the optical signal will not be able to be transmitted normally. In this case, it is necessary to turn off the laser transmitter to ensure the safety of laser transmission and avoid accidents.

[0157] If the laser transmitter and optical cable get too hot during optical signal transmission, it may cause some equipment to burn out or other unexpected phenomena. In order to avoid such unexpected phenomena, the transmission power of the laser transmitter can be reduced or the laser transmitter can be turned off to ensure the safety of laser transmission.

[0158] If the laser transmitter is in an abnormal operating state, or if the actual transmitted power of the optical signal emitted by the laser transmitter is not the output power set by the power regulator, or if the wavelength information of the actual emitted optical signal is not the wavelength information set by the controller or power regulator, the optical signal transmitted by the laser transmitter may not meet the service requirements of the second device. In this case, it is also necessary to shut down the laser transmitter, check the problem causing the above situation, and solve the problem, so as to ensure that the optical signal emitted by the laser transmitter can meet the service requirements of the backend second device.

[0159] In this signal transmission system, by adding a power regulator to the first optoelectronic component, the transmission power and wavelength information of the optical signal transmitted by the first optoelectronic component 101 through the optical cable 102 can be dynamically adjusted according to the real-time service requirements of the equipment, making the power supply and data transmission process for the second equipment more flexible and accurate.

[0160] In some high-power laser transmission scenarios, if the laser transmitter malfunctions, the high-power laser transmitted by the laser transmitter and optical cable may cause harm to the surrounding environment or personnel. By setting this power regulator, the working status of the laser transmitter can be monitored, and if the working status is abnormal, the transmission power of the laser transmitter can be reduced or the laser transmitter can be shut down in an emergency. This reduces or avoids harm to the surrounding environment and personnel during laser transmission, ensuring the safety of laser transmission. At the same time, it also helps to avoid damage to other components in the signal transmission system caused by the abnormal situation, allowing other components to operate normally, which helps to ensure the safety and stability of each component in the signal transmission system.

[0161] (3) Laser emitter 1013

[0162] The laser emitter 1013 can be used to generate a corresponding optical signal based on wavelength information, and to transmit the optical signal to the second optoelectronic component 103 via optical cable 102 based on transmission power. It should be noted that the process by which the laser emitter generates the corresponding optical signal based on wavelength information in this embodiment can be referred to... Figure 4 The process by which the laser emitter generates the corresponding optical signal based on the wavelength information in the embodiment will not be described in detail here.

[0163] (4) Detector 1015

[0164] The detector 1015 is used to acquire the operating data of the laser emitter 1013 and send the operating data to the power regulator 1014.

[0165] Optionally, the detector 1015 can be a sensor used to implement security monitoring functions, and can be used to detect at least one of the following: whether there are obstacles in the optical signal transmission path, the temperature of the laser transmitter and optical cable during optical signal transmission, the transmission power and photoelectric conversion efficiency of the optical signal emitted by the laser transmitter, and the wavelength information of the optical signal emitted by the laser transmitter.

[0166] Optionally, the detector 1015 can also be communicatively connected to the controller 104. The detector 1015 can send the operating data to the controller 104, so that the controller 104 can determine the operating status of the laser emitter 1013 based on the operating data; and, in the case that the operating status of the laser emitter is abnormal, it can send an adjustment command to the power regulator 1014, which is used to instruct the power regulator 1014 to reduce the transmission power of the laser emitter 1013 or turn off the laser emitter 1013.

[0167] In this signal transmission system, by adding a detector to the first optoelectronic component, the working status of the laser transmitter can be monitored in real time. This allows for timely reduction of the laser transmitter's transmission power or shutdown when the laser transmitter's working status is abnormal, thus preventing accidents and ensuring the safety of laser transmission.

[0171] In signal transmission systems, energy storage components can be installed to store electrical energy, allowing for timely allocation of power to the second device based on its real-time power supply needs. For example, when the second device's power demand is low, the energy storage component can store excess energy; when the second device's power demand increases, some of the stored energy can be used to power the second device. This improves the flexibility and stability of the signal transmission system's power supply and enables efficient utilization of electrical energy.

[0172] In some embodiments, the second optoelectronic component 103 may further include a monitoring component 1035, which may be connected to the optoelectronic converter 1032 and the energy storage component 1034 respectively.

[0173] The monitoring component 1035 can be used to acquire the photoelectric conversion efficiency and power output data of the photoelectric converter 1032.

[0174] Photoelectric conversion efficiency can be defined as the efficiency with which a power supply optical signal is converted into electrical energy. In one example, this photoelectric conversion efficiency can be the ratio between the power of the power supply optical signal and the output power of the power supply optical signal converted into electrical energy.

[0175] The power output data may include the output power of the electricity output by the photoelectric converter.

[0176] The monitoring component 1035 can also be used to monitor the energy storage capacity and power supply data of the energy storage component 1034. The power supply data may include the voltage and power supplied by the energy storage component to the second device.

[0177] In some embodiments, the monitoring component 1035 can be communicatively connected to the controller 104, and the monitoring component 1035 can send the photoelectric conversion efficiency and power output data of the photoelectric converter 1032, as well as the energy storage capacity and power supply data of the energy storage component 1034 to the controller 104.

[0178] The controller 104 can adjust the power supply from the signal transmission system (or energy storage component 1034) to the second device in a timely manner based on the photoelectric conversion efficiency, power output data, energy storage capacity, power supply data, and the power supply requirements of the second device. This optimizes energy use in the signal transmission system, improves energy utilization efficiency, and reduces energy waste. The signal transmission system can flexibly adjust the power supply to the second device according to the power supply requirements of various types of connected second devices (e.g., high-power second devices or second devices with special requirements). This allows the signal transmission system to provide efficient and stable power supply services to second devices with different power consumption needs, making it suitable for various application scenarios and highly adaptable.
