Description

Technical Field

[0001] This application relates to the field of communications, and in particular to an Ethernet signal conversion and communication apparatus, method, device, medium and product. Background Technology

[0002] In industrial control, data communication, and remote monitoring, traditional Ethernet communication (RJ45 interface) is widely used. These technologies rely on copper wires to transmit signals and have the following characteristics:

[0003] (1) Maturity: Ethernet communication technology has been developed for many years, and equipment compatibility and cost control are relatively mature.

[0004] (2) Popularity: As a standard Ethernet interface, the RJ45 interface is widely used in most industrial control equipment.

[0005] (3) Short-distance advantage: In short-distance transmission (usually less than 100 meters), copper wire transmission has lower cost and more flexible deployment.

[0006] However, with the upgrading of industrial application requirements and the increasing complexity of communication environments, traditional Ethernet technology has exposed obvious limitations and has the following problems:

[0007] (1) Electromagnetic interference:

[0008] In complex electromagnetic environments (such as near industrial production lines and power equipment), copper wire transmission is susceptible to electromagnetic waves, radio frequency interference, and power surges, leading to signal attenuation or communication interruption. Furthermore, electromagnetic interference issues limit the reliability of Ethernet transmission, especially in mission-critical communications in industrial control.

[0009] (2) Distance restrictions:

[0010] RJ45 copper wire transmission is limited by physical characteristics, and the maximum transmission distance is usually about 100 meters, which is difficult to meet the needs of long-distance communication. In communication scenarios that require longer distances, existing solutions often need to add repeater equipment, which increases costs and maintenance complexity.

[0011] (3) Insufficient reliability:

[0012] Copper wire transmission interfaces are susceptible to external environmental factors (such as humidity and temperature changes), leading to performance degradation or even hardware damage; lack of effective isolation measures (such as electromagnetic isolation) makes them prone to hardware failure in extreme environments; and the lines are susceptible to rodent damage and human-caused damage.

[0013] (4) High maintenance costs: Existing solutions require additional protection equipment (such as shielding wires and grounding devices) to reduce interference, but these devices increase deployment and maintenance costs. Summary of the Invention

[0014] The purpose of this application is to provide an Ethernet signal conversion and communication device, method, equipment, medium and product to solve the problems of electromagnetic interference, distance limitation, low reliability and high maintenance cost in Ethernet data transmission.

[0015] To achieve the above objectives, this application provides the following solution:

[0016] In a first aspect, this application provides an Ethernet signal conversion and communication device, comprising:

[0017] The signal processing module is connected to the RJ45 interface and is used to convert the Ethernet data of the RJ45 interface into optical data and send the optical data to the photoelectric conversion module in the form of an electrical signal.

[0018] The photoelectric conversion module is connected to the signal processing interface and is used to parse the optical data in the electrical signal and transmit it to the plastic optical fiber interface.

[0019] The plastic optical fiber interface is connected to the photoelectric conversion module and is used to send the optical data to the plastic optical fiber communication link for signal transmission.

[0020] Secondly, this application provides a method for converting and communicating Ethernet signals, including:

[0021] The signal processing module converts the Ethernet data from the RJ45 interface into optical data, and then sends the optical data to the photoelectric conversion module in the form of an electrical signal.

[0022] The photoelectric conversion module is used to analyze the optical data in the electrical signal and transmit it to the plastic optical fiber interface;

[0023] The optical data is transmitted to the plastic optical fiber communication link using the plastic optical fiber interface for signal transmission.

[0024] Thirdly, this application provides a computer device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the above-described Ethernet signal conversion and communication method.

[0025] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-described Ethernet signal conversion and communication method.

[0026] Fifthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements the above-mentioned Ethernet signal conversion and communication method.

[0027] According to the specific embodiments provided in this application, the following technical effects are disclosed:

[0028] This application converts Ethernet data from an RJ45 interface into optical data, and then uses a photoelectric conversion module to parse the optical data from the electrical signal, transmitting it to a plastic optical fiber interface. Signal transmission is then achieved via a plastic optical fiber communication link. Because the plastic optical fiber communication link replaces the traditional copper wire transmission method of the RJ45 interface, it significantly reduces the impact of electromagnetic interference on data transmission, making it particularly suitable for complex electromagnetic environments in industrial control settings. Furthermore, compared to RJ45 copper wire transmission, the plastic optical fiber communication link enables high-speed data transmission over longer distances, increasing the transmission distance. In addition, the use of a plastic optical fiber communication link avoids various defects of copper wire transmission, thereby improving transmission reliability and eliminating the need for additional protection equipment, thus reducing maintenance costs.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 As shown, this application provides an Ethernet signal conversion and communication device, comprising:

[0035] Signal processing module 1, connected to RJ45 interface 6, is used to convert Ethernet data of RJ45 interface 6 into optical data and send the optical data to photoelectric conversion module 2 in the form of electrical signals.

[0036] The photoelectric conversion module 2 is connected to the signal processing interface and is used to analyze the optical data in the electrical signal and transmit it to the plastic optical fiber interface 3.

[0037] The plastic optical fiber interface 3 is connected to the photoelectric conversion module 2 and is used to send the optical data to the plastic optical fiber communication link for signal transmission.

[0038] In one exemplary instance, RJ45 interface 6 is used to receive and transmit standard Ethernet signals.

[0039] Connection relationship: Connected to signal processing module 1, responsible for inputting external Ethernet data to signal processing module 1.

[0040] In an exemplary embodiment, the signal processing module 1 specifically includes:

[0041] The parsing and extraction unit is used to parse the frame structure of the Ethernet data and extract the valid data in the frame structure.

[0042] The conversion unit is used to convert the valid data into optical data and send the optical data to the photoelectric conversion module 2 in the form of an electrical signal.

[0043] Furthermore, the signal processing module 1 can be a T5L, which is used to parse the frame structure of Ethernet data, extract the effective data (data body) and convert it into optical data for transmission and send it to the photoelectric conversion module in the form of an electrical signal.

[0044] Connection relationship: The input end is connected to the RJ45 interface 6 for receiving Ethernet data; the output end is connected to the photoelectric conversion module 2 for transmitting the processed electrical signal.

[0045] In an exemplary embodiment, the photoelectric conversion module 2 is further configured to receive optical data transmitted by the plastic optical fiber communication link through the plastic optical fiber interface 3, and convert the optical data back into an electrical signal, which is then transmitted to the signal processing module 1.

[0046] Furthermore, the photoelectric conversion module 2 is a module responsible for bidirectional conversion between electrical signals and optical data.

[0047] Photoelectric conversion module 2 has the following functions:

[0048] Photoelectric conversion: Converts the electrical signals sent by signal processing module 1 into optical data to adapt to plastic optical fiber transmission.

[0049] Photoelectric conversion: At the receiving end, the optical data is converted back into an electrical signal and transmitted to the signal processing module 1.

[0050] Connection relationship: The input end receives electrical signals from the signal processing module 1; the output end is connected to an external plastic optical fiber link through the plastic optical fiber interface 3.

[0051] The photoelectric conversion module 2 is also responsible for receiving optical data from the external plastic optical fiber link and converting it back into an electrical signal, which is then transmitted to the signal processing module 1.

[0052] In one exemplary embodiment, the plastic fiber optic interface 3 is an input and output port for optical data, used to support standard plastic fiber optic connections.

[0053] Connection relationship: Connected to photoelectric conversion module 2, used for optical data transmission and reception.

[0054] Furthermore, other types of high-speed, interference-resistant communication media can be used instead of the plastic fiber optic interface 3, for example:

[0055] a. Coaxial cable: Utilizing its anti-interference capability and signal stability to replace plastic optical fiber for transmission.

[0056] b. Shielded twisted pair cable: Through high-quality shielding, it enhances anti-interference capabilities and extends transmission distance.

[0057] The communication medium is not limited to plastic optical fiber; it can be extended to any medium that has anti-interference and long-distance transmission capabilities.

[0058] However, coaxial cables and shielded twisted pairs are still inferior to plastic fiber optic interfaces 3 in terms of anti-interference and transmission distance, and are easily affected by the external electromagnetic environment. It can be seen that plastic fiber optic interfaces 3 have the best transmission effect and the lowest cost.

[0059] In one exemplary embodiment, the RJ45 interface 6 communicates bidirectionally with the plastic optical fiber interface 3.

[0060] In one exemplary embodiment, it further includes: a protection circuit module 4; the protection circuit module 4 is disposed between the RJ45 interface 6 and the signal processing module 1, and is used to prevent overcurrent, overvoltage and electrostatic damage.

[0061] Furthermore, the protection circuit module 4 is used to prevent damage from overcurrent, overvoltage and electrostatic discharge, ensuring the long-term stable operation of the RJ45 interface 6 and the signal processing module 1.

[0062] Connection relationship: Protects RJ45 interface 6 and signal processing module 1, and enhances anti-interference capability.

[0063] In an exemplary embodiment, it further includes: a power management module 5; the power management module 5 is connected to the RJ45 interface 6, the signal processing module 1 and the photoelectric conversion module 2, and is used to provide power.

[0064] This application supports bidirectional communication of signals in both forward and reverse directions, ensuring signal integrity and stability whether the signal travels from RJ45 interface 6 to the plastic fiber optic link or back from the plastic fiber optic link to RJ45 interface 6. Bidirectional transmission ensures that this application is adaptable to various communication scenarios, further enhancing application flexibility.

[0065] This application has the following significant advantages:

[0066] (1) Enhance anti-interference capability:

[0067] Replacing traditional copper wire transmission with plastic optical fiber communication links significantly reduces the impact of electromagnetic interference on data transmission, making it particularly suitable for complex electromagnetic environments in industrial control settings.

[0068] By utilizing the photoelectric conversion module 2, electromagnetic interference during signal transmission is effectively avoided by taking advantage of the photoelectric isolation characteristics.

[0069] (2) Improve communication quality and stability:

[0070] The module employs a high-efficiency signal processing module 1 and a photoelectric conversion module 2 to ensure data transmission with a zero error rate (≤10). -9 The signal transmission is more stable.

[0071] The signal processing module 1 and the photoelectric conversion module ensure accurate signal conversion and stable transmission.

[0072] (3) Supports high-speed transmission over longer distances:

[0073] Compared to traditional RJ45 copper wire interfaces, plastic fiber optic transmission can achieve high-speed data transmission over longer distances (supporting 2400, 4800, 9600, and 115200 bps / s).

[0074] The plastic fiber optic interface 3 and the photoelectric conversion module 2 provide a physical basis for adapting to high bandwidth.

[0075] (4) High reliability and low maintenance requirements:

[0076] The module has built-in protection circuitry to prevent equipment damage caused by power surges, overvoltage, or static electricity, thereby reducing operating and maintenance costs.

[0077] (5) Energy-saving design:

[0078] The module features low power consumption, ≤0.2W, which meets the high energy efficiency requirements of industrial equipment and is particularly suitable for industrial control applications that operate for extended periods.

[0079] The power management module 5 of this application optimizes energy consumption distribution.

[0080] The reasons for the aforementioned advantages of this application are as follows:

[0091] Distributed modules: Signal processing and photoelectric conversion functions are separated into multiple modules to flexibly adapt to different application scenarios. Distributed modules may increase the complexity of hardware deployment, but still meet the purpose of this technology in terms of functional implementation.

[0097] In practical applications, S2 can be supplemented with corresponding auxiliary steps during signal conversion, for example:

[0099] b. Add decoding or repair steps after signal reception to enhance the reliability of data transmission.

[0100] This application includes various combinations of signal processing, conversion, verification, encoding, transmission and decoding, but a. these methods may increase the computational complexity of the system and require further optimization of the function implementation.
