Description

Technical Field

[0001] The present invention relates to the technical field of signal transmission, and particularly to a signal enhancement system for long-distance transmission of copper wire production data in a high-temperature environment. Background Art

[0002] In the industrial scenario of copper processing, production equipment in large-area workshops usually requires long-distance data transmission, and the environmental temperature often exceeds 60°C. The traditional solution of using industrial Ethernet copper cables with repeaters has significant defects: The impedance characteristics of copper cables drift at high temperatures, resulting in non-linear attenuation of signal amplitude with the transmission distance. Existing repeaters use fixed gain compensation and cannot adapt to the dynamically changing attenuation curve. Especially when the temperature fluctuates, the bit error rate increases sharply; repeaters need to be independently powered and installed in a protective box, and are prone to overheating and crashing in high-temperature areas. When a fault occurs, manual segment-by-segment troubleshooting is required, and the average repair time exceeds 2 hours; the fiber optic replacement solution requires modification of the existing equipment interfaces, and fiber optic connectors are prone to deterioration in high-temperature and high-humidity environments.

[0003] Therefore, there is an urgent need for a signal enhancement system for long-distance transmission of copper wire production data in a high-temperature environment that is embedded in the transmission copper cable. Summary of the Invention

[0004] In view of at least one of the above technical problems, the present invention provides a signal enhancement system for long-distance transmission of copper wire production data in a high-temperature environment, which can effectively solve the problems in the background art.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: A signal enhancement system for long-distance transmission of copper wire production data in a high-temperature environment, comprising: Shielded twisted pair; Signal enhancement modules, distributed at a set spacing along the shielded twisted pair and electrically connected to the shielded twisted pair; The signal enhancement module includes: A signal analysis unit for detecting signal characteristic parameters of the transmitted signal; An environmental parameter acquisition unit for acquiring environmental characteristic parameters; An adaptive compensator for dynamically adjusting the compensation parameters of the signal enhancement module according to the correlation between the signal characteristic parameters and the environmental characteristic parameters; A power supply unit for providing power for the operation of the signal enhancement system; Wherein, the signal enhancement modules implement an in-band communication protocol through the shielded twisted pair to perform cascade synchronization of the compensation parameters.

[0006] Further, the electrical connection between the signal enhancement module and the shielded twisted pair is specifically: Laser-weld the signal terminals of the signal enhancement module to the cores of the shielded twisted pair cable; Mechanically connect the housing of the signal enhancement module to the shielded twisted pair cable; Set a sealing and heat-insulating layer on the outer surface of the signal enhancement module.

[0007] Furthermore, the signal enhancement modules implement an in-band communication protocol through the shielded twisted pair cable to perform cascaded synchronization of the compensation parameters, including: Divide a set number of adjacent signal enhancement modules into a first-level synchronization unit; Perform independent synchronization of the compensation parameters in each level of the synchronization unit.

[0008] Furthermore, performing independent synchronization of the compensation parameters in each level of the synchronization unit includes: Calculate the average value or weighted average value of the parameters of each signal enhancement module in each level of the synchronization unit and record it as the compensation parameter; Alternatively, select one signal enhancement module from each level of the synchronization unit as the master node, and determine the compensation parameter according to the difference degree of the environmental characteristic parameters between the remaining signal enhancement modules and the master node.

[0009] Furthermore, the adaptive compensator generates the compensation parameter based on a pre-trained attenuation prediction model according to the correlation between the signal characteristic parameters and the environmental characteristic parameters.

[0010] Furthermore, the attenuation prediction model is an LSTM neural network model.

[0011] Furthermore, when there is a faulty signal enhancement module in the synchronization unit, exclude the faulty signal enhancement module from the synchronization unit and reconstruct this synchronization unit; Among them, after the synchronization unit excludes the faulty signal enhancement module, if the number of signal enhancement modules in this synchronization unit is less than the set number value, merge it with the adjacent synchronization unit to form a new synchronization unit.

[0012] Furthermore, the power supply unit includes: The main power supply circuit; The backup power supply circuit, which is composed of a super capacitor; Among them, when the main power supply circuit of the signal enhancement system is interrupted, the backup power supply circuit is started.

[0013] Furthermore, the environmental characteristic parameters include environmental temperature data; When the main power supply circuit of the signal enhancement system is interrupted, starting the backup power supply circuit includes: When the interruption of the main power supply circuit is detected, the supercapacitor power supply is started, and a power supply relay request is sent to the adjacent signal enhancement module. After the request is successful, the power supply priority is dynamically adjusted based on the real-time ambient temperature data. The signal enhancement module with an ambient temperature higher than the set threshold is withdrawn from the backup power supply circuit, and the signal enhancement module with an ambient temperature lower than or equal to the set threshold is connected to the backup power supply circuit to perform the backup power supply work.

[0014] Further, when the main power supply circuit is interrupted, the signal enhancement system starts the backup power supply circuit, including: Judging whether the power supply duration of the supercapacitor is greater than the set time threshold. If so, the corresponding signal enhancement module is connected to the backup power supply circuit to perform the backup power supply work; otherwise, the corresponding signal enhancement module is withdrawn from the backup power supply circuit.

[0015] Through the technical solution of the present invention, the following technical effects can be achieved: Through the present invention, the technical problem of long-distance copper cable transmission in an industrial high-temperature environment is effectively solved, and the following remarkable beneficial effects are specifically generated: First, the micro signal enhancement module adopts a structural design of direct coupling with the cable core by laser welding, realizing the integrated fusion of the signal compensation device and the transmission line, not only improving the long-term reliability of the system in harsh environments such as high temperature and high humidity, but also completely avoiding problems such as the need for additional wiring and installation of protective chassis for traditional external relay devices. Second, the compensation mechanism based on the deep learning model dynamically generates the optimal compensation scheme by real-time analyzing the characteristics of the transmission signal and the changes in environmental parameters, and cooperates with the in-band communication and unit synchronization strategy between modules, enabling the system to autonomously adapt to the wide temperature range change from low temperature to high temperature, effectively overcoming the inherent defects such as impedance characteristic drift and non-linear signal attenuation aggravation of copper cable transmission under high temperature conditions. Third, the power supply relay mechanism between modules ensures that even in extreme cases such as main power failure, the key transmission nodes can still maintain normal operation, greatly improving the overall fault tolerance and operation stability of the system.

[0016] On the premise of keeping the traditional copper cable wiring structure unchanged, the present invention can achieve high-quality signal transmission similar to optical fiber transmission only by embedding enhancement modules, avoiding the high cost of comprehensively replacing the optical fiber network and retaining the inherent advantages of copper cable such as anti-mechanical shock and easy installation and maintenance.

Detailed implementation manners

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] As Figure 1 shown, the signal enhancement system for long-distance transmission of copper wire production data in a high-temperature environment of the present invention includes: Shielded twisted pair; Signal enhancement modules, distributed at a set spacing along the shielded twisted pair and electrically connected to the shielded twisted pair; The signal enhancement module includes: A signal analysis unit for detecting the signal characteristic parameters of the transmitted signal; An environmental parameter acquisition unit for acquiring environmental characteristic parameters; An adaptive compensator that dynamically adjusts the compensation parameters of the signal enhancement module according to the correlation between the signal characteristic parameters and the environmental characteristic parameters; A power supply unit for providing the operating power of the signal enhancement system; Among them, the signal enhancement modules implement an in-band communication protocol through shielded twisted pairs to cascade and synchronize the compensation parameters.

[0023] In this embodiment, in a high-temperature environment, long-distance data transmission through copper cables faces problems such as intensified nonlinear signal attenuation and thermal expansion deformation of the cables. Through the combined design of the conduction of shielded twisted pairs and distributed signal enhancement modules, the inherent defects of copper cable transmission under high-temperature conditions can be effectively overcome. The shielded twisted pair backbone has a high-temperature insulating layer made of PTFE or XLPE materials, which can prevent short circuits between wires caused by high-temperature softening. To effectively manage signal attenuation and noise, the signal enhancement modules are distributed along the shielded twisted pair at a set spacing, and the physical attenuation limit is broken through by segmented compensation, and the signal attenuation is controlled within a repairable range within each section; during implementation, the signal enhancement modules are conducted with the shielded twisted pair to ensure efficient signal injection, impedance continuity, and high-temperature reliability.

[0024] The signal enhancement modules directly use the data transmission channel itself to implement the in-band communication protocol, and cascade and synchronize the compensation parameters through the in-band communication protocol. The in-band communication protocol realizes the efficient co-line transmission of control signals and production data by multiplexing the physical medium of the shielded twisted pair. Its reliable operation depends on the quality of the conduction process, realizing the integrated fusion of the signal enhancement module and the transmission line. The two jointly ensure the stability of the communication link in high-temperature and high-interference environments, not only improving the long-term reliability of the system in harsh environments such as high temperature and high humidity, but also completely avoiding the need for additional wiring for traditional external relay devices, significantly improving the environmental adaptability and maintainability of the system.

[0025] The signal analysis unit adopted in the present invention is used to detect signal characteristic parameters such as the amplitude and signal-to-noise ratio of the transmitted signal; the environmental parameter acquisition unit is used to collect environmental characteristic parameters such as environmental temperature, environmental humidity, and electromagnetic interference intensity; the above-listed parameters are all specific examples of this embodiment and are not used to limit the protection scope of the present invention. Other detectable and collectable parameters are also within the protection scope of the present invention. In a long-distance transmission system for copper wire production data in a high-temperature environment, the signal characteristics and environmental parameters are dynamically changing. To ensure the reliability and stability of transmission, the adaptive compensator set in the signal enhancement module analyzes the correlation between the signal characteristic parameters and the environmental characteristic parameters, and dynamically adjusts the compensation parameters of the internal circuit of the signal enhancement module, such as gain coefficient, noise threshold, pre-emphasis factor, etc., to respond in real time to the dynamic changes of temperature, humidity, and interference, breaking through the physical limitations of fixed compensation.

[0026] Through the present invention, the long-term reliability of the system in harsh environments such as high temperature and high humidity is improved. Additionally, problems such as the need for additional wiring and the installation of protective enclosures for traditional external relay devices are completely avoided. Moreover, by dynamically generating an optimal compensation scheme through an adaptive compensator, the system can autonomously adapt to the wide temperature range change from low temperature to high temperature, effectively overcoming the inherent defects of copper cable transmission such as impedance characteristic drift and increased signal attenuation non-linearity under high temperature conditions. On the premise of keeping the traditional copper cable wiring structure unchanged, the present invention can achieve high-quality signal transmission similar to optical fiber transmission only by embedding an enhancement module, which not only avoids the high cost of comprehensively replacing the optical fiber network but also retains the inherent advantages of copper cable such as resistance to mechanical shock and ease of installation and maintenance.

[0027] As a preference of the above embodiment, the signal enhancement module is electrically connected to the shielded twisted pair. Specifically: The signal terminals of the signal enhancement module are laser welded to the cores of the shielded twisted pair; The housing of the signal enhancement module is mechanically connected to the shielded twisted pair; A sealed heat insulation layer is provided along the outer surface of the signal enhancement module.

[0028] In an industrial high-temperature environment, traditional connection methods such as crimping may result in poor contact due to thermal expansion. In contrast, the metallurgical bond formed by laser welding is more stable, providing lower contact resistance and higher reliability, ensuring the minimization of signal transmission loss. Therefore, through a precise laser welding process, the module signal terminals and the twisted pair cores are bonded at the molecular level to form a continuous conductive path. The welding process is completed under the protection of inert gas to ensure that the joints are resistant to high-temperature oxidation. In this embodiment, the module housing is connected to the cable shield layer through a mechanical structure. Through this embedding process, the module becomes an intrinsic functional unit of the cable rather than an external device, fundamentally ensuring the reliability of the system under harsh working conditions such as high temperature and vibration. Additionally, a sealed heat insulation layer is coated on the outer surface of the signal enhancement module. Specifically, a 360° full-perimeter sealed heat insulation can be formed through vacuum injection molding of the heat insulation layer, thereby solving the problem of the impact of high-temperature environment on electronic components. The heat insulation layer can reduce the transfer of external heat to the inside of the module, protecting the internal circuit, and the seal can also prevent dust and moisture from entering, improving the durability of the module.

[0029] As a preference of the above embodiment, to optimize communication efficiency, as Figure 2 shown, an in-band communication protocol is implemented between signal enhancement modules through shielded twisted pairs to cascade and synchronize compensation parameters, including: Adjacent signal enhancement modules in a set number are divided into a first-level synchronization unit; Independent compensation parameter synchronization is performed within each level of synchronization unit.

[0030] In the present invention, a cascaded synchronization mechanism is implemented to synchronize compensation parameters in units of synchronization units. During the cascaded synchronization process, adjacent and a set number of micro signal enhancement modules are selected as first-level synchronization units, which can reduce communication overhead, improve the system response speed, and enhance the fault tolerance of the system. For example, if all modules participate in global synchronization, when the network scale is very large, communication delay and complexity will increase. After dividing into units, agreement can be quickly reached within each unit, reducing the overall delay. In addition, when a certain unit fails, it will not affect the normal operation of other units, improving the robustness of the system. Independent compensation parameter synchronization is performed in each level of synchronization units. Each synchronization unit adjusts the compensation parameters according to its own environmental parameters without being affected by other units, which can better adapt to changes in the local environment and improve the adaptability of the system. For example, if a certain synchronization unit is in a high-temperature area, its compensation parameters will emphasize temperature-related adjustments more, while another synchronization unit in a high-interference area will pay more attention to noise suppression.

[0031] Based on the above embodiments, independent compensation parameter synchronization is performed in each level of synchronization units, including: Calculating the average value or weighted average value of the parameters of each signal enhancement module in each level of synchronization unit and recording it as the compensation parameter; Alternatively, select a signal enhancement module from each level of synchronization unit as the master node, and determine the compensation parameter according to the difference degree of the environmental characteristic parameters between the remaining signal enhancement modules and the master node.

[0032] In the above embodiments, the final compensation parameter can be directly calculated in the synchronization unit by means of average value, weighted average value, etc., which can integrate the data of all nodes, reduce the influence of abnormal data of individual nodes, and is suitable for scenarios with uniform environment and high reliability, improving the robustness through data fusion; or select one of the signal enhancement modules as the master node. The master node needs to have high reliability, and determine the compensation parameter according to the difference degree of the environmental characteristic parameters between other signal enhancement modules and the master node, which performs better in scenarios with significant environmental gradients or requiring fast response.

[0033] As a preference of the above embodiments, the adaptive compensator generates the compensation parameter based on a pre-trained attenuation prediction model according to the correlation relationship between the signal characteristic parameters and the environmental characteristic parameters.

[0034] Based on the above embodiments, the attenuation prediction model is an LSTM neural network model.

[0035] In signal transmission, environmental characteristic parameters and signal characteristic parameters may change over time, such as temperature fluctuations and changes in electromagnetic interference. LSTM is a long short-term memory network, which is suitable for time series prediction. Therefore, using the LSTM neural network model can capture these temporal dependencies, predict the signal attenuation trend, and thus dynamically adjust the compensation parameters. It is difficult to obtain sufficient labeled data in the industrial field. And to reduce the cost of repeated training, the adaptive compensator generates compensation parameters through a pre-trained attenuation prediction model. Compared with training the attenuation prediction model from scratch, choosing the pre-trained model reduces the data requirements, and only a small amount of on-site data is needed to adjust the model parameters, quickly adapting to the actual environment of the production line.

[0036] Further, when there is a faulty signal enhancement module in the synchronization unit, the faulty signal enhancement module is excluded from the synchronization unit, and this synchronization unit is reconstructed. Among them, after the synchronization unit excludes the faulty signal enhancement module, if the number of signal enhancement modules in this synchronization unit is less than the set number value, it is merged with the adjacent synchronization unit to form a new synchronization unit.

[0037] In the above optimization scheme, through the setting of the synchronization unit, single-point temperature mutations only affect the parameters of this unit, avoiding the spread of faults. When there is a module fault in the unit, it can be quickly isolated and the synchronization group can be reconstructed by excluding individual signal enhancement modules. If the number of modules is too small after isolation, it can also be merged with the adjacent synchronization unit to ensure that each synchronization unit has enough modules to maintain effective parameter synchronization and signal compensation.

[0038] As a preference of this embodiment, the power supply unit includes: The main power supply circuit; The backup power supply circuit, which is composed of supercapacitors; Among them, when the main power supply circuit is interrupted, the signal enhancement system starts the backup power supply circuit.

[0039] Specifically, the power supply unit of the signal enhancement module sets the main power supply circuit to provide the working power of the signal enhancement system. The main power supply circuit may be interrupted due to grid faults, line damage or other reasons. Without a backup power supply, the system will stop working immediately, resulting in data transmission interruption, which may cause serious problems in industrial production, such as production line shutdown and data loss. Therefore, the power supply unit also sets a backup power supply circuit. The existence of the backup power supply ensures that when the main power supply fails, the system can still run for a period of time to safely shut down or maintain key functions. In a high-temperature environment, ordinary batteries may experience performance degradation or even damage, while supercapacitors are more suitable for such harsh conditions. Therefore, the backup power supply circuit of the power supply unit is composed of supercapacitors. The supercapacitor has a high power density and can quickly provide a large current, which is suitable for coping with sudden power demands, such as the instantaneous high power consumption of the signal enhancement module during power switching.

[0040] Based on the above embodiments, the environmental characteristic parameters include environmental temperature data; As Figure 3 shown, when the main power supply circuit is interrupted, the signal enhancement system activates the backup power supply circuit, including: When it is detected that the main power supply circuit is interrupted, activate the supercapacitor power supply and send a power supply relay request to adjacent signal enhancement modules; After the request is successful, dynamically adjust the power supply priority based on real-time environmental temperature data, withdraw the signal enhancement modules with environmental temperatures higher than the set threshold from the backup power supply circuit, and connect the signal enhancement modules with environmental temperatures lower than or equal to the set threshold to the backup power supply circuit to perform the backup power supply work.

[0041] In this embodiment, the power supply priority is dynamically adjusted by temperature. When it is detected that the main power supply is interrupted, the supercapacitor power supply is activated and a power supply relay request is sent to adjacent modules. When the request reaches other signal enhancement modules, the modules can share the backup power supply to form a collaborative network, improving the reliability of the overall system. Modules with too high a temperature may have a higher risk of failure, or the performance of their electronic components may decline. Continuing to supply power may cause damage or inefficiency. The system will give priority to shutting down these modules and leaving the power to the modules with lower temperatures. Therefore, in this embodiment, a threshold is set so that the modules with environmental temperatures higher than the set threshold will withdraw from the backup power supply mode and enter the low-power mode first, while the relatively low-temperature micro signal enhancement modules will relay to perform the backup power supply work. The power supply relay mechanism between modules ensures that even in extreme situations such as main power failure, key transmission nodes can still maintain normal operation, greatly enhancing the overall fault tolerance and operational stability of the system.

[0042] Furthermore, when the main power supply circuit is interrupted, the signal enhancement system activates the backup power supply circuit, including: Judge whether the power supply duration of the supercapacitor is greater than the set time threshold. If so, connect the corresponding signal enhancement module to the backup power supply circuit to perform the backup power supply work; otherwise, withdraw the corresponding signal enhancement module from the backup power supply circuit.

[0043] When setting up the backup power supply in the above embodiments, the backup power supply is implemented through a supercapacitor. The power supply duration of the supercapacitor needs to be greater than the set time threshold to ensure the good performance of the backup function. Specifically, the capacity of the supercapacitor is limited, and the system needs to estimate the time it can maintain power supply. If the power supply duration of the supercapacitor exceeds the set threshold, the module is allowed to continue using the backup power supply; otherwise, it is shut down in advance to avoid data loss or hardware damage caused by sudden power failure. This embodiment optimizes the use efficiency of the backup power supply and improves the reliability of the system by means of a collaborative mechanism of power supply priority adjustment driven by ambient temperature and intelligent judgment of the power supply duration of the supercapacitor, intelligently isolating the thermal risk nodes and prolonging the device life.

[0044] Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
