Description

Technical Field

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

[0002] In the copper processing industry, production equipment within large factory buildings often requires long-distance data transmission, and the ambient temperature often exceeds 60°C. The traditional solution of using industrial Ethernet copper cables with repeaters has significant drawbacks:

[0003] Copper cables' impedance characteristics drift at high temperatures, causing nonlinear attenuation of signal amplitude over transmission distance. Existing repeaters use fixed gain compensation, which cannot adapt to dynamically changing attenuation curves, especially when subjected to temperature fluctuations, causing a sharp increase in bit error rates. Repeaters require independent power supplies and are installed in protective enclosures, making them prone to overheating and downtime in high-temperature areas. Faults require manual troubleshooting in sections, with an average repair time exceeding two hours. Fiber replacement solutions require modifying existing equipment interfaces, and fiber connectors are susceptible to degradation in high-temperature and high-humidity environments.

[0004] Therefore, there is an urgent need for a copper wire production data long-distance transmission signal enhancement system embedded in a transmission copper cable under a high temperature environment. Summary of the Invention

[0005] 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 technology.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A copper wire production data long-distance transmission signal enhancement system in a high-temperature environment, comprising:

[0008] Shielded twisted pair cable;

[0009] a signal enhancement module, distributed along the shielded twisted pair at a set interval and electrically connected to the shielded twisted pair;

[0010] The signal enhancement module includes:

[0011] A signal analysis unit, configured to detect characteristic parameters of a transmission signal;

[0012] Environmental parameter collection unit, collecting environmental characteristic parameters;

[0013] an adaptive compensator, which dynamically adjusts the compensation parameters of the signal enhancement module according to the correlation between the signal characteristic parameters and the environmental characteristic parameters;

[0014] A power supply unit, used to provide working power for the signal enhancement system;

[0015] The signal enhancement modules implement an in-band communication protocol through the shielded twisted pair cables to perform cascade synchronization of the compensation parameters.

[0016] Furthermore, the signal enhancement module is connected to the shielded twisted pair, specifically:

[0017] Laser welding the signal terminal of the signal enhancement module and the core of the shielded twisted pair cable;

[0018] Connecting the housing of the signal enhancement module and the shielded twisted pair cable through a mechanical structure;

[0019] A sealing and heat-insulating layer is provided along the outer surface of the signal enhancement module.

[0020] Furthermore, the signal enhancement modules implement an in-band communication protocol through the shielded twisted pair cables to perform cascade synchronization of the compensation parameters, including:

[0021] Dividing a set number of adjacent signal enhancement modules into primary synchronization units;

[0022] The compensation parameter synchronization is performed independently in the synchronization unit at each level.

[0023] Furthermore, performing independent compensation parameter synchronization in each level of the synchronization unit includes:

[0024] Calculating an average value or a weighted average value of various parameters of each signal enhancement module in each level of the synchronization unit and recording the result as the compensation parameter;

[0025] Alternatively, one signal enhancement module is selected from each level of the synchronization unit as a master node, and the compensation parameter is determined according to the degree of difference between the environmental characteristic parameters of the remaining signal enhancement modules and the master node.

[0026] Furthermore, the adaptive compensator generates the compensation parameter based on a pre-trained attenuation prediction model and according to the correlation between the signal characteristic parameter and the environmental characteristic parameter.

[0027] Furthermore, the attenuation prediction model is an LSTM neural network model.

[0028] Furthermore, when a faulty signal enhancement module exists in the synchronization unit, the faulty signal enhancement module is removed from the synchronization unit and the synchronization unit is reconstructed;

[0029] Wherein, after the synchronization unit eliminates the faulty signal enhancement module, if the number of the signal enhancement modules in the synchronization unit is less than a set number value, it is merged with the adjacent synchronization unit to form a new synchronization unit.

[0030] Furthermore, the power supply unit includes:

[0031] Main power supply circuit;

[0032] A backup power supply circuit, consisting of a supercapacitor;

[0033] Wherein, the signal enhancement system starts the backup power supply circuit when the main power supply circuit is interrupted.

[0034] Furthermore, the environmental characteristic parameters include environmental temperature data;

[0035] The signal enhancement system starts the backup power supply circuit when the main power supply circuit is interrupted, including:

[0036] When it is detected that the main power supply circuit is interrupted, the supercapacitor is started to supply power and a power supply relay request is sent to the adjacent signal enhancement module;

[0037] After the request is successful, the power supply priority is dynamically adjusted based on the real-time ambient temperature data, the signal enhancement module when the ambient temperature is higher than the set threshold is removed from the backup power supply circuit, and the signal enhancement module when the ambient temperature is lower than or equal to the set threshold is connected to the backup power supply circuit to perform backup power supply work.

[0038] Furthermore, when the main power supply circuit is interrupted, the signal enhancement system starts the backup power supply circuit, including:

[0039] Determine whether the power supply duration of the supercapacitor is greater than a set time threshold. If so, connect the corresponding signal enhancement module to the backup power supply circuit to perform backup power supply work; otherwise, withdraw the corresponding signal enhancement module from the backup power supply circuit.

[0040] The technical solution of the present invention can achieve the following technical effects:

[0041] The present invention effectively solves the technical challenges of long-distance copper cable transmission in industrial high-temperature environments, producing the following significant beneficial effects: First, the micro-signal enhancement module adopts a structural design that is directly coupled to the cable core through laser welding, realizing the integration of signal compensation devices and transmission lines. This not only improves the long-term reliability of the system in harsh environments such as high temperature and high humidity, but also completely avoids the problems of traditional external relay equipment requiring additional wiring and protective chassis. Second, the compensation mechanism based on a deep learning model dynamically generates the optimal compensation scheme by analyzing the transmission signal characteristics and environmental parameter changes in real time. Combined with the in-band communication and unitized synchronization strategy between modules, the system can autonomously adapt to a wide range of temperature changes from low to high temperatures, effectively overcoming the inherent defects of copper cable transmission under high temperature conditions, such as impedance characteristic drift and increased nonlinear signal attenuation. Furthermore, 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 improving the overall fault tolerance and operational stability of the system.

[0042] While maintaining the traditional copper cable wiring structure unchanged, the present invention can achieve high-quality signal transmission similar to that of optical fiber transmission only through the embedded enhancement module, avoiding the high cost of completely replacing the optical fiber network while retaining the inherent advantages of copper cables such as resistance to mechanical shock and easy installation and maintenance.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] like Figure 1 As shown, the copper wire production data long-distance transmission signal enhancement system in a high-temperature environment of the present invention includes:

[0051] Shielded twisted pair cable;

[0052] The signal enhancement module is distributed along the shielded twisted pair at a set interval and is connected to the shielded twisted pair;

[0053] The signal enhancement module includes:

[0054] A signal analysis unit, configured to detect characteristic parameters of a transmission signal;

[0055] Environmental parameter collection unit, collecting environmental characteristic parameters;

[0056] An adaptive compensator that dynamically adjusts the compensation parameters of the signal enhancement module based on the correlation between signal characteristic parameters and environmental characteristic parameters;

[0057] A power supply unit, used to provide working power for the signal enhancement system;

[0058] Among them, the signal enhancement modules implement in-band communication protocol through shielded twisted pair cables to perform cascade synchronization of compensation parameters.

[0059] In this embodiment, under high temperature environment, long-distance data transmission of copper cable faces problems such as increased nonlinear signal attenuation and thermal expansion deformation of cables. The combined design of shielded twisted pair and distributed signal enhancement module can effectively overcome the inherent defects of copper cable transmission under high temperature conditions. The shielded twisted pair trunk has a high-temperature insulation layer made of PTFE or XLPE material, which can prevent high-temperature softening and short circuit between wires. In order to effectively manage signal attenuation and noise, the signal enhancement module is distributed at a set interval along the shielded twisted pair, and the physical attenuation limit is broken through by segmented compensation, and the signal attenuation in each section is controlled within a repairable range. During the implementation process, the signal enhancement module and the shielded twisted pair are turned on to ensure efficient signal injection, impedance continuity and high-temperature reliability.

[0060] The signal enhancement modules directly utilize the data transmission channel itself to implement the in-band communication protocol, and achieve cascade synchronization of compensation parameters through the in-band communication protocol. The in-band communication protocol realizes efficient co-linear transmission of control signals and production data by reusing the physical medium of shielded twisted pair cables. Its reliable operation depends on the quality of the conduction process, realizing the integrated fusion of signal enhancement modules and transmission lines. The two together ensure the stability of the communication link in high temperature and high interference environments, which not only improves the long-term reliability of the system in harsh environments such as high temperature and high humidity, but also completely avoids the need for additional wiring of traditional external relay equipment, significantly improving the environmental adaptability and maintainability of the system.

[0061] The signal analysis unit used in the present invention is used to detect the amplitude, signal-to-noise ratio and other signal characteristic parameters of the transmission signal; the environmental parameter acquisition unit is used to acquire environmental characteristic parameters such as ambient temperature, ambient humidity, and electromagnetic interference intensity; the parameters listed above are all specific examples of this embodiment and are not intended to limit the scope of protection of the present invention. Other detectable and acquired parameters are also within the scope of protection 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 provided 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 the gain coefficient, noise threshold, pre-emphasis factor, etc., to respond to the dynamic changes of temperature, humidity, and interference in real time, breaking through the physical limitations of fixed compensation.

[0062] The present invention improves the system's long-term reliability in harsh environments such as high temperature and high humidity, completely avoiding the problems associated with traditional external relay equipment, such as the need for additional wiring and protective enclosures. Furthermore, by dynamically generating an optimal compensation solution through an adaptive compensator, the system can autonomously adapt to a wide temperature range, from low to high. This effectively overcomes the inherent drawbacks of copper cable transmission at high temperatures, such as impedance drift and increased nonlinear signal attenuation. While maintaining the traditional copper cable wiring structure, the present invention achieves high-quality signal transmission similar to that of fiber optic transmission solely through the use of an embedded enhancement module. This avoids the high cost of a complete fiber optic network replacement while retaining the inherent advantages of copper cable, such as mechanical shock resistance and ease of installation and maintenance.

[0063] As a preferred embodiment of the above, the signal enhancement module is connected to the shielded twisted pair, specifically:

[0064] Laser welding the signal terminals of the signal enhancement module and the cores of the shielded twisted pair cables;

[0065] Connecting the housing of the signal enhancement module and the shielded twisted pair cable through a mechanical structure;

[0066] A sealing insulation layer is provided along the outer surface of the signal enhancement module.

[0067] In high-temperature industrial environments, traditional connection methods such as crimping may cause poor contact due to thermal expansion, while the metallurgical bond formed by laser welding is more stable, can provide lower contact resistance and higher reliability, and ensure that signal transmission loss is minimized. Therefore, a precision laser welding process is used to achieve molecular-level bonding between the module signal terminals and the twisted pair core to form a continuous conductive path. The welding process is completed under the protection of inert gas to ensure that the contacts are resistant to high-temperature oxidation. In this embodiment, the module shell is connected to the cable shielding layer through a mechanical structure. Through this embedding process, the module becomes an intrinsic functional unit of the cable rather than an external component, fundamentally ensuring the reliability of the system under harsh working conditions such as high temperature and vibration. In addition, a sealed insulation layer is coated on the outer surface of the signal enhancement module. Specifically, a 360° full-circumference sealed insulation layer can be formed by vacuum injection molding, thereby solving the problem of the impact of high-temperature environments on electronic components. The insulation layer can reduce the transfer of external heat to the interior of the module, protecting the internal circuit. The seal can also prevent dust and moisture from entering, improving the durability of the module.

[0068] As a preference of the above embodiment, in order to optimize communication efficiency, as Figure 2 As shown, the signal enhancement modules implement an in-band communication protocol through a shielded twisted pair cable to perform cascade synchronization of compensation parameters, including:

[0069] Dividing a set number of adjacent signal enhancement modules into a first-level synchronization unit;

[0070] Independent compensation parameter synchronization is performed in each level of synchronization unit.

[0071] In the present invention, a cascade synchronization mechanism is implemented, and compensation parameter synchronization is performed in units of synchronization units. During the cascade synchronization process, adjacent and set numbers of micro-signal enhancement modules are selected as first-level synchronization units, which can reduce communication overhead, improve 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 large, communication delay and complexity will increase, while after the units are divided, consensus can be quickly reached within each unit, reducing overall delay. In addition, when a unit fails, it will not affect the normal operation of other units, thereby improving the robustness of the system. Independent compensation parameter synchronization is performed in each level of synchronization unit. Each synchronization unit adjusts the compensation parameters according to its own environmental parameters without being affected by other units. It can better adapt to changes in the local environment and improve the adaptability of the system. For example, if a synchronization unit is in a high-temperature area, its compensation parameters will emphasize temperature-related adjustments more, while another synchronization unit is in a high-interference area and pays more attention to noise suppression.

[0072] Based on the above embodiment, independent compensation parameter synchronization is performed in each synchronization unit, including:

[0073] Calculate the average value or weighted average value of various parameters of each signal enhancement module in each level of synchronization unit and record it as the compensation parameter;

[0074] Alternatively, a signal enhancement module is selected from each level of synchronization unit as a master node, and the compensation parameters are determined according to the degree of difference between the environmental characteristic parameters of the remaining signal enhancement modules and the master node.

[0075] In the above embodiment, the final compensation parameters can be directly calculated in the synchronization unit using methods such as average value, weighted average value, etc., which can integrate the data of all nodes and reduce the impact of abnormal data of individual nodes. It is suitable for scenarios with uniform environment and high reliability requirements, and improves robustness through data fusion; or, one of the signal enhancement modules is selected as the main node. The main node needs to have higher reliability, and the compensation parameters are determined according to the degree of difference between the environmental characteristic parameters of other signal enhancement modules and the main node. It performs better in scenarios with significant environmental gradients or requiring rapid response.

[0076] As a preferred embodiment of the above embodiment, the adaptive compensator generates compensation parameters based on a pre-trained attenuation prediction model and according to the correlation between signal characteristic parameters and environmental characteristic parameters.

[0077] Based on the above embodiment, the attenuation prediction model is an LSTM neural network model.

[0078] During signal transmission, environmental 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 suitable for time series prediction. Therefore, the LSTM neural network model can capture these temporal dependencies, predict signal attenuation trends, and dynamically adjust compensation parameters. It is difficult to obtain sufficient labeled data at industrial sites, 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, the pre-trained model reduces data requirements and only requires a small amount of field data to adjust the model parameters, allowing for rapid adaptation to the actual production line environment.

[0079] Furthermore, when a faulty signal enhancement module exists in the synchronization unit, the faulty signal enhancement module is excluded from the synchronization unit and the synchronization unit is reconstructed;

[0080] Wherein, after the synchronization unit removes 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.

[0081] In the above optimization scheme, through the setting of the synchronization unit, a single-point temperature mutation and the like only affect the parameters of this unit, thus avoiding the spread of faults. When a module fails within 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 after isolation is too small, they can also be merged with adjacent synchronization units to ensure that each synchronization unit has enough modules to maintain effective parameter synchronization and signal compensation.

[0082] As a preferred embodiment of this invention, the power supply unit includes:

[0083] Main power supply circuit;

[0084] A backup power supply circuit, consisting of a supercapacitor;

[0085] Among them, the signal enhancement system starts the backup power supply circuit when the main power supply circuit is interrupted.

[0086] Specifically, the power supply unit of the signal enhancement module is provided with a main power supply circuit to provide working power for the signal enhancement system. The main power supply circuit may be interrupted due to grid failure, line damage or other reasons. If there is no 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, data loss, etc. Therefore, the power supply unit is also provided with a backup power supply circuit. The existence of the backup power supply ensures that when the main power supply fails, the system can still maintain operation for a period of time so that it can be safely shut down or maintain key functions. In a high temperature environment, ordinary batteries may degrade in performance or even be damaged, and supercapacitors are more suitable for such harsh conditions. Therefore, the backup power supply circuit of the power supply unit is composed of supercapacitors. Supercapacitors have high power density and can quickly provide large currents, which are suitable for responding to sudden power demands, such as the instantaneous high power consumption of the signal enhancement module during power switching.

[0087] Based on the above embodiment, the environmental characteristic parameters include environmental temperature data;

[0088] like Figure 3 As shown, when the main power supply circuit is interrupted, the signal enhancement system starts the backup power supply circuit, including:

[0089] When the main power supply circuit is detected to be interrupted, the supercapacitor is started to supply power and a power relay request is sent to the adjacent signal enhancement module;

[0090] 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 removed 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 backup power supply work.

[0091] This embodiment dynamically adjusts the power supply priority by temperature. When a main power supply interruption is detected, the supercapacitor power supply is started and a power supply relay request is sent to the adjacent module. When the request reaches other signal enhancement modules, the modules can share the backup power supply to form a collaborative network, thereby improving the reliability of the overall system. Modules with too high a temperature may have a higher risk of failure, or their electronic components may have degraded performance. Continuing to supply power may cause damage or inefficiency. The system will prioritize shutting down these modules and leaving power for modules with lower temperatures. Therefore, this embodiment sets a threshold so that modules with an ambient temperature higher than the set threshold will prioritize exiting the backup power supply mode and entering the low-power mode, while the micro-signal enhancement modules with relatively low temperatures will relay 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 improving the overall fault tolerance and operational stability of the system.

[0092] Furthermore, when the main power supply circuit is interrupted, the signal enhancement system starts the backup power supply circuit, including:

[0093] Determine whether the power supply duration of the supercapacitor is greater than a set time threshold. If so, connect the corresponding signal enhancement module to the backup power supply circuit to perform backup power supply work; otherwise, remove the corresponding signal enhancement module from the backup power supply circuit.

[0094] When the above embodiment sets the backup power supply, the backup power supply is realized by a supercapacitor. The power supply duration of the supercapacitor must 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 to use the backup power supply; otherwise, it is shut down in advance to avoid data loss or hardware damage caused by sudden power outages. This embodiment uses a collaborative mechanism of power supply priority adjustment driven by ambient temperature and intelligent judgment of supercapacitor power supply duration to intelligently isolate thermal risk nodes, extend equipment life, optimize the efficiency of backup power use, and improve system reliability.
