[0002] The SRB bus is easily affected by electromagnetic interference in the electromagnetic compatibility immunity test, especially the high-intensity immunity test, which leads to data link failure.

[0003] In the traditional solution, in order to improve the electromagnetic compatibility of the SRB bus, the first way is to use higher quality shielding materials, which undoubtedly increases the hardware cost. The second way is to design special electromagnetic compatibility circuits, such as filtering circuits, isolation circuits, etc. The design of these circuits needs to consider many factors, such as interference frequency, interference intensity, signal characteristics, etc., which are difficult to design and difficult to implement. Therefore, it is difficult for the traditional solution to solve the problem that the SRB bus is easily affected by external interference and causes data errors in the electromagnetic compatibility immunity test without increasing the hardware cost.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the professional terms involved in the embodiments of the present application will be explained below.

[0027] SRB bus: Secure Real-time Bus (SRB), uses shielded twisted pair as the transmission medium. The communication protocol ensures that the data transmission delay between devices is minimized and supports real-time communication.

[0028] PHY chip: physical layer interface chip, used for network interface conversion.

[0029] Immunity test in electromagnetic compatibility test: evaluate the stability of data transmission cables under external electromagnetic interference.

[0030] Single-mode optical fiber: used to transmit optical signals with a wavelength of 1310 / 1550nm, with a theoretical transmission distance of more than 10 kilometers and anti-electromagnetic interference capability.

[0031] To facilitate understanding of the technical solutions provided by the embodiments of the present application, the background technology involved in the embodiments of the present application will be described below.

[0032] As mentioned above, the core technical feature of the SRB bus as a secure real-time bus is that it uses a pair of shielded twisted-pair cables as the transmission medium, which is designed to minimize the data transmission delay between devices and achieve real-time communication. However, this transmission method faces a series of technical and cost challenges in practical applications. The SRB bus is based on the transmission method of shielded twisted-pair cables, and its theoretical maximum transmission distance is limited to 40 meters. For application scenarios that require data transmission over longer distances, this limitation obviously cannot meet the needs.

[0033] When conducting the immunity test in the electromagnetic compatibility test, the shielded twisted pair is easily affected by external interference. These interference waveforms may be transmitted to the chip through the cable, resulting in data errors or even the chip not working properly. This situation not only affects the stability of data transmission, but also puts extremely high requirements on the shielding effect of the twisted pair, thereby increasing the manufacturing cost of the twisted pair and the difficulty of designing the electromagnetic compatibility circuit.

[0034] The current SRB bus bandwidth based on twisted pair transmission is 100Mbps. If the bandwidth needs to be increased to 1000Mbps (i.e. Gigabit Ethernet standard), although the data transmission rate can be significantly improved, the risk of data reliability will also be greatly increased. Because higher transmission rates mean shorter transmission time windows, higher requirements are placed on data synchronization, signal integrity, and error detection.

[0035] In order to solve the above problems, an embodiment of the present application provides a link structure for improving the wired transmission distance of a secure real-time bus SRB. In actual application scenarios, due to the limitations of its physical properties, the theoretical maximum transmission distance of the SRB bus is only 40 meters, which limits its application in scenarios requiring long-distance data transmission. The present application successfully bypasses the limitation of the SRB bus transmission distance by introducing a first transmission structure and a second transmission structure, and using single-mode optical fiber for data transmission between them. Single-mode optical fiber has extremely low attenuation and extremely high bandwidth, and can support long-distance, high-speed data transmission, thereby solving the problem of insufficient stability of long-distance data transmission.

[0036] The SRB bus is susceptible to electromagnetic interference in electromagnetic compatibility immunity tests, especially high-intensity immunity tests, which can cause data link failure. This is because the shielding effect of twisted pair as a transmission medium is limited, and it is difficult to completely isolate external electromagnetic interference. This application physically isolates the influence of electromagnetic interference by using optical fiber as a transmission medium. Optical fiber transmission signals are carried out in the form of light and are not interfered by electromagnetic fields, so the electromagnetic compatibility of data links can be significantly improved.

[0037] In the traditional solution, in order to improve the electromagnetic compatibility of the SRB bus, it is necessary to use a special shielded twisted pair and design a special electromagnetic compatibility circuit, which undoubtedly increases the hardware cost. However, this application adopts optical fiber transmission, which not only solves the electromagnetic compatibility problem, but also avoids the use of expensive shielded twisted pair and complex electromagnetic compatibility circuit design, thereby reducing the overall hardware cost.

[0038] The present application introduces optical fiber transmission technology and sets a first transmission structure and a second transmission structure to effectively solve the defects of the SRB bus in the prior art in terms of long-distance data transmission stability and electromagnetic compatibility. Therefore, the link structure provided by the embodiment of the present application not only improves the stability and reliability of data transmission, but also reduces hardware costs.

[0039] It should be noted that the link structure and mobile terminal provided in the present application can be applied to the field of data transmission technology. The above is only an example and does not limit the application field of the link structure and mobile terminal provided in the present application. In addition, the embodiments of the present application may not limit the execution device involved in the link structure. For example, the link structure of the embodiment of the present application can be applied to data processing devices such as terminal devices or servers. Among them, the terminal device can be an electronic device such as a smart phone, a computer, a personal digital assistant (PDA), etc. The server can be a stand-alone server, a cloud server, or a cluster server composed of multiple servers.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The following describes a link structure provided by the present application through an embodiment. Figure 1 , Figure 1 A first link structure schematic diagram provided for an embodiment of the present application includes: a first host, a second host, a first transmission structure, and a second transmission structure;

[0042] The first host and the first transmission structure transmit data via an SRB bus, the first transmission structure and the second transmission structure transmit data via a single-mode optical fiber, and the second transmission structure and the second host transmit data via an SRB bus.

[0043] The first host can be the starting point of the data, connected to the first transmission structure through the SRB bus. The second host can be the end point of the data, also connected to the second transmission structure through the SRB bus.

[0044] The first transmission structure is responsible for converting the data received from the first host into a format suitable for single-mode optical fiber transmission and sending it through the single-mode optical fiber. The first transmission structure may include necessary electronic components (such as chips, interface circuits, etc.) for converting the SRB bus data received from the first host into a format suitable for transmission on a single-mode optical fiber (such as an optical signal). The converted data is then sent to the single-mode optical fiber through the optical module (or optical transmitter) in the first transmission structure. Exemplarily, this conversion may include processes such as data encoding and modulation to ensure that the data can be effectively transmitted in the optical fiber in the form of an optical signal.

[0045] As a data transmission channel between the first transmission structure and the second transmission structure, single-mode optical fiber has extremely high bandwidth potential and a long transmission distance. At the same time, it can resist electromagnetic interference and ensure the integrity and security of data transmission.

[0046] The second transmission structure is responsible for receiving data from the single-mode optical fiber, converting it back to a format recognizable by the SRB bus, and transmitting it to the second host. This structure is responsible for converting the optical signal back to an electrical signal and performing necessary decoding, demodulation and other processing to restore the original SRB bus data format. Then, these data are sent to the second host via the SRB bus.

[0047] Both the SRB bus and single-mode optical fiber support high-speed data transmission, allowing the entire link structure to meet application scenarios with high bandwidth requirements. The transmission distance of single-mode optical fiber far exceeds that of traditional copper wire or twisted pair, and is suitable for scenarios where data transmission needs to be carried out over longer distances. Optical fiber transmission is not affected by electromagnetic interference, and the attenuation of optical signals in optical fibers is small, which improves the reliability and stability of data transmission. By adjusting the conversion logic in the first transmission structure and the second transmission structure, the link structure can adapt to the data transmission requirements of different formats and protocols.

[0048] In a possible implementation, the second host may also serve as the starting point of data transmission, and be connected to the first transmission structure via the SRB bus. The first host may also serve as the end point of data transmission.

[0049] See also Figure 2 , Figure 2 A second link structure schematic diagram provided for an embodiment of the present application, wherein the first transmission structure includes a first group of chips and a first optical module, the first transmission structure includes a second group of chips and a second optical module, the first group of chips is used to convert data transmitted by the first host via the SRB bus into a preset mode for optical module input, and transmit it to the first optical module; the first optical module transmits the data to the second optical module via a single-mode optical fiber; the second optical module transmits the data in the preset mode to the second group of chip structures, the second group of chip structures converts the received data into an SRB bus format, and transmits it to the second host.

[0050] The first group of chips is responsible for the preliminary processing of the data received from the first host through the SRB bus. Their main function is to convert the data into a preset pattern that can be recognized and processed by the optical module for subsequent optical signal conversion and transmission. This process can include steps such as data formatting, encoding, and clock synchronization. Once the data is converted into a preset pattern, the first optical module will take over. The optical module is a key component of optoelectronic conversion, which can convert electrical signals (here, processed data) into optical signals and transmit them through single-mode optical fibers. This process can involve modulation technology, that is, loading the data signal onto the optical carrier.

[0051] Single-mode optical fiber is used as a medium for data transmission. With its low attenuation, high bandwidth and long transmission distance, single-mode optical fiber ensures that data can be efficiently and stably transmitted from the first optical module to the second optical module.

[0052] When the optical signal reaches the second optical module through the single-mode optical fiber, the second optical module performs photoelectric conversion, that is, converts the optical signal back into an electrical signal. This process is the reverse process of the operation of the first optical module, which involves demodulation technology, that is, recovering the original data signal from the optical carrier. The second group of chips is responsible for further processing the data received from the second optical module. Their main function is to convert the data from the preset mode back to a format that the SRB bus can recognize. This process may include steps such as decoding, data reorganization, and clock recovery to ensure that the data can be accurately transmitted to the second host through the SRB bus.

[0053] Through the cooperation of the first chip group, the first optical module, the single-mode optical fiber, the second optical module and the second chip group, the link structure realizes efficient and reliable data transmission from the first host to the second host, and improves the flexibility and scalability of the system through modular design.

[0054] See also Figure 3 , Figure 3 A third link structure schematic diagram is provided for an embodiment of the present application, wherein the first group of chips includes a first chip and a second chip, and the second group of chips includes a third chip and a fourth chip. The first chip is used to convert data received through an SRB bus into a preset interface format and send it to the second chip, and the second chip is used to convert the received data into the preset mode; the fourth chip is used to convert the received data in the preset mode into a preset interface format and send it to the third chip, and the third chip is used to convert the received data into an SRB bus format and transmit it to a second host.

[0055] The first chip is the starting point for data reception and preliminary processing. The first chip is responsible for preliminary format conversion or preprocessing of the data received from the SRB bus and converting it into a preset interface form. This interface form may be designed to work better with the second chip, and may involve operations such as data synchronization, alignment, or simple encoding. After the second chip receives the data sent by the first chip, the second chip is responsible for further converting the data into the preset mode required by the optical module. This preset mode matches the optoelectronic conversion characteristics of the optical module and may include specific data encoding, modulation methods, or clock synchronization requirements.

[0056] The fourth chip serves as the entry point of the second group of chips. The fourth chip is responsible for performing preliminary interface conversion on the preset mode data received from the second optical module. This conversion may be designed to work better with the third chip, and it may involve operations such as data decoding, alignment, or synchronization. After the third chip receives the data sent by the fourth chip, the third chip is responsible for converting the data into a format that can be recognized by the SRB bus and transmitting the data to the second host via the SRB bus. This conversion process may include steps such as data reorganization, decoding, and clock recovery to ensure that the data can be accurately received and processed by the second host.

[0057] Through the coordinated work of the first chip, the second chip, the single-mode optical fiber, the fourth chip, and the third chip, the link structure realizes efficient and accurate data transmission from the first host to the second host. Each chip undertakes a specific data processing task, thus ensuring the smoothness and reliability of the entire transmission process. This refined chip division of labor improves the flexibility and scalability of the link structure.

[0058] See also Figure 4 , Figure 4 The fourth link structure schematic diagram provided in the embodiment of the present application, the second chip is used to convert the received data into the 1000BASE-X protocol mode; the fourth chip is used to convert the received data in the 1000BASE-X protocol mode into a preset interface format and send it to the third chip.

[0059] 1000BASE-X is an Ethernet physical layer standard that supports Gigabit Ethernet transmission, where "X" represents a different physical medium, such as optical fiber. In this context, it can refer to the Gigabit Ethernet protocol transmitted over single-mode optical fiber.

[0060] In a possible implementation, the second chip is used to convert the received data into a 1000BASE-X protocol mode; the fourth chip is used to convert the received data in the 1000BASE-X protocol mode into an RGMII interface format and send it to the third chip.

[0061] The fourth chip receives the electrical signal from the second optical module (i.e., data in the 1000BASE-X protocol mode) and converts it into an RGMII (Reduced Gigabit Media Independent Interface) interface format. RGMII is an interface standard for connecting between the Gigabit Ethernet MAC layer and the PHY layer, which simplifies the number of pins and reduces costs while maintaining the high-speed transmission capability of Gigabit Ethernet.

[0062] The data is converted from the SRB bus to the 1000BASE-X protocol mode and then to the RGMII interface during transmission. This conversion ensures that data can be transmitted efficiently and accurately between different hardware interfaces and protocols.

[0063] The following Figure 4 The data transmission process is described in the following.

[0064] First, the data generated by the first host is first transmitted to the physical layer interface chip, namely the first chip, through the SRB bus (a pair of twisted pairs with shielded layers). In this process, the data generated by the first host is transmitted on the twisted pair in the form of electrical signals.

[0065] The first chip converts the received data from the original format into the RGMII (Reduced Gigabit Media Independent Interface) interface format. The converted RGMII interface data is sent to another physical layer interface chip (the second chip).

[0066] The second chip further converts the RGMII interface data into 1000BASE-X protocol mode. 1000BASE-X is an Ethernet physical layer standard that supports Gigabit Ethernet transmission. The data is then sent out in the form of single-mode optical fiber through an optical module. Single-mode optical fiber serves as the main transmission medium for data in this process, and its theoretical transmission distance can exceed 10 kilometers. In addition, the optical signal transmitted by single-mode optical fiber is not affected by external electromagnetic interference, which greatly enhances the stability and reliability of data transmission.

[0067] After transmitting over a long distance, the second optical module receives the optical signal transmitted from the single-mode optical fiber, converts the received optical signal back into data in the 1000BASE-X protocol mode, and sends it to the second chip.

[0068] The second chip receives the 1000BASE-X protocol data from the second optical module, and converts the data back to the RGMII interface format.

[0069] The third chip converts the data of the RGMII interface into the form of SRB bus (twisted pair) again. The converted data is transmitted to the second host through the SRB bus, completing the entire data transmission process.

[0070] In summary, the entire data transmission process of the method provided in the embodiment of the present application realizes efficient, reliable and long-distance data transmission from the first host to the second host through the cooperation of multiple physical layer interface chips (PHY chips) and the conversion of different communication protocols (such as RGMII, 1000BASE-X) and transmission media (such as twisted pair, single-mode optical fiber). In particular, the introduction of single-mode optical fiber greatly improves the distance and anti-interference ability of data transmission.

[0071] In a possible implementation, a management node is further included, and the management node is used to send configuration information to at least one of the first host, the second host, the first transmission structure, and the second transmission structure. In addition to the management node, the SRB bus structure may also include a terminal node, wherein there may be two terminal nodes, one as a transmitting end and the other as a receiving end.

[0072] In the SRB bus structure, the terminal node can be a host. They are the starting point and end point of data transmission and are responsible for generating, processing and receiving data. The management node is an abstract concept. It can be implemented by a device or a combination of multiple devices in the system. The function of the management node can be implemented by a dedicated network device, server or embedded system. It can communicate with the terminal node (such as the host) through the preset network to perform resource management and scheduling tasks.

[0073] In actual network deployment, the management node can be one or more devices with processing capabilities, which run a network operating system and corresponding management software, can process requests from terminal nodes, monitor network status, and make corresponding resource allocation decisions. The host, PHY chip, optical module, etc. described in the embodiments of this application are hardware components that implement the functions of the physical layer and data link layer, which are responsible for the actual transmission of data and signal conversion, and realize the tasks assigned by the management node.

[0074] The management node plays a core control role in the link, and is mainly responsible for resource management and scheduling of the entire link structure. Its core functions include resource allocation, recycling, distribution of system configuration, and dynamic allocation of communication bandwidth. The terminal node is the basic data exchange unit in the link, and is mainly responsible for receiving, processing, and sending data. They can be directly connected to the management node, and through the scheduling and configuration of the management node, the real-time transmission of data is completed.

[0075] In a possible implementation, the management node is responsible for monitoring resource usage in the entire network, including node status, bandwidth usage, etc., to ensure reasonable allocation and utilization of resources.

[0076] In one possible implementation, the management node may push system configuration information, including network topology, communication protocol parameters, etc., to each terminal node in real time according to actual network needs, to ensure that each node can communicate according to unified rules.

[0077] In a possible implementation, the management node can allocate network bandwidth in real time according to the number of hosts and the amount of data in the network, optimize network traffic and reduce congestion. For example, when the amount of data of a node surges within a certain period of time, the management node can increase the bandwidth allocation of the node in real time to ensure real-time transmission of data.

[0078] In a possible implementation, the management node may divide the time into multiple microsecond (μs) time periods and arrange a time window for data transmission for each node, thereby minimizing transmission delay.

[0079] In one possible implementation, the management node can apply advanced scheduling algorithms to ensure fair and efficient allocation of time slices. Technologies such as priority queues and weighted fair queues (WFQ) can also be used to handle data flows of different priorities.

[0080] Therefore, through intelligent bandwidth allocation and resource management, the management node can significantly improve the data transmission efficiency of the entire network. In addition, through precise time division and dynamic bandwidth adjustment mechanism, the real-time requirements of data transmission are guaranteed.

[0081] In a possible implementation, the terminal node may be synchronized with the time of the management system to ensure that data is correctly sent and received within the allocated time period.

[0082] The terminal nodes can include precise time synchronization mechanisms, such as the Network Time Protocol (NTP) or the Precision Time Protocol (PTP), so that the terminal nodes have efficient data caching and fast data processing capabilities to adapt to the microsecond transmission time window.

[0083] In a possible implementation, the received data may be processed as necessary at the terminal node, such as data analysis, storage, forwarding, etc. The processed data may be sent to the management node or other terminal nodes via the SRB bus to achieve real-time data interaction.

[0084] Regarding the collaborative work process between the management node and the terminal node, the terminal node directly exchanges data with the management node and transmits data according to the instructions of the management node. In addition, the data interaction between the management node and the terminal node can be highly synchronized and coordinated. The terminal node receives data from the management node or other terminal nodes in real time, including system configuration information, business data, etc. The terminal node can also feedback its own working status to the management node in real time, including the amount of data received, the amount of data sent, the error rate, etc., so that the management node can adjust and optimize resources.

[0085] Exemplarily, the scheduling decision of the management node is communicated to the terminal node within a first preset time, and the terminal node needs to complete the sending and receiving of data within a second preset time.

[0086] Moreover, in actual application scenarios, the management node can dynamically adjust the resource allocation strategy according to the actual operation of the network to optimize system performance and response speed. For example, the management node can allocate network bandwidth in real time according to the number of network communication hosts and the amount of data. By subdividing a long time period (such as 100ms) into multiple microsecond (μs) time periods, it is ensured that each node can complete data transmission in a short time, thereby reducing the overall transmission delay to the microsecond level. Therefore, through the allocation of microsecond time periods, the management node can ensure that each terminal node can obtain the necessary bandwidth resources even under high load conditions, thereby ensuring the real-time nature of data transmission.
