In the prior art, some solutions attempt to define frequency bands through software or introduce a single anti-interference algorithm, but lack the collaborative optimization of multi-dimensional parameters (such as frequency bands, power, and noise suppression), and cannot adapt to the dynamic changes of power grid noise. In addition, existing systems lack a dynamic interaction mechanism for parameter configuration tables, resulting in limited communication efficiency. Summary of the Invention

[0036] The HPLC communication module includes a carrier signal generator, a coupling circuit, and a modulation and demodulation unit, supporting multi-band dynamic switching from 2 MHz to 12 MHz.

[0037] (2) Dynamic parameter configuration table module

[0038] The dynamic parameter configuration table module is used to store the frequency band selection rule, power spectral density limit value, and anti-interference parameter optimization strategy related to the power grid environment.

[0039] The dynamic parameter configuration table module includes:

[0040] a. The associated mapping between the working frequency band priority and the power grid noise distribution;

[0041] b. Dynamic adaptation of power spectral density limit to frequency band width;

[0042] c. Reverse compensation strategy for anti-attenuation performance threshold and communication rate.

[0043] The anti-interference performance includes:

[0044] 1> When the packet error rate < 10% and the in-band emission power spectral density is -45 dBm / Hz, the anti-narrowband interference performance ≥ 90 dB;

[0045] 2> The anti-pulse interference performance is ≥ 80 dB in frequency band 1 and ≥ 70 dB in frequency band 2;

[0046] 3> The anti-white noise performance ≥ 60 dB.

[0047] The dynamic parameter configuration table module updates itself based on historical communication data through self-learning to optimize the frequency band selection rule and the anti-interference parameter optimization strategy.

[0048] (3) Intelligent matching algorithm module

[0049] The intelligent matching algorithm module is used to match the optimal communication parameters from the dynamic parameter configuration table module according to the real-time channel quality data.

[0050] The intelligent matching algorithm module receives the channel quality data transmitted by the HPLC communication module, combines the frequency band selection rule in the dynamic parameter configuration table module, and dynamically adjusts the communication parameters through the intelligent matching algorithm module;

[0051] The intelligent matching algorithm module is also used to analyze historical data to optimize the frequency band selection rule and the anti-interference parameter optimization strategy, and write the updated parameters into the dynamic parameter configuration table module.

[0052] (4) Feedback control module

[0053] The feedback control module is used to dynamically adjust the working frequency band and transmission power of the HPLC communication module based on the channel quality data (packet error rate, signal attenuation data).

[0054] The communication process among the above four modules is as follows:

[0055] Initialization of HPLC module: The HPLC communication module includes a carrier signal generator, a coupling circuit and a modulation and demodulation unit, and supports multi-band dynamic switching from 2 MHz to 12 MHz. When the system starts, the HPLC module reads the initial communication parameters from the parameter configuration table, including the working frequency band, power spectral density limit, etc., and completes the initialization configuration.

[0056] Data acquisition and transmission: The HPLC module collects communication data on the power line in real time and converts the signal into a digital signal through the modulation and demodulation unit. At the same time, the HPLC module monitors channel quality data, including the packet error rate (PER), signal attenuation (RSSI), etc., and transfers this data to the intelligent algorithm module.

[0057] Dynamic interaction of the parameter configuration table: The parameter configuration table stores frequency band selection rules, power spectral density limits, anti-interference parameter optimization strategies, etc. related to the power grid environment. The HPLC module reads the initial parameters from the parameter configuration table during initialization and dynamically updates the parameter configuration table according to the feedback from the intelligent algorithm module during operation.

[0058] Optimization processing of the intelligent algorithm module: The intelligent algorithm module receives the channel quality data (such as packet error rate, signal attenuation) transmitted by the HPLC module, and combines the rules in the parameter configuration table to dynamically adjust the communication parameters through an intelligent matching algorithm. For example, select the optimal frequency band according to the power grid noise distribution, adjust the power spectral density to adapt to the frequency band width, and optimize the anti-interference strategy to improve communication stability.

[0059] Dynamic adjustment of the feedback control module: The feedback control module dynamically adjusts the working frequency band and transmission power of the HPLC module according to the output result of the intelligent algorithm module. For example, when narrowband interference is detected, the feedback control module will switch to a frequency band with stronger anti-interference performance and reduce the transmission power to reduce energy consumption.

[0060] Self-learning update of the parameter configuration table: The parameter configuration table supports self-learning update based on historical communication data. During the operation of the system, the intelligent algorithm module analyzes the historical data, optimizes the frequency band switching rules and anti-interference strategies, and writes the updated parameters into the parameter configuration table to improve the long-term adaptability of the system.

[0061] Closed-loop optimization process: The entire system realizes the establishment of an adaptive communication link through a closed-loop optimization process. The HPLC module collects real-time data, the intelligent algorithm module performs optimization processing, the feedback control module adjusts the communication parameters, and the parameter configuration table dynamically updates the rules, forming a closed-loop optimization mechanism.

[0062] The present invention also provides an HPLC communication parameter dynamic optimization method, based on the parameter configuration-driven HPLC communication unit collaborative system as described above. The method specifically includes:

[0063] S1. The HPLC communication module retrieves the initial frequency band and power spectral density parameters from the dynamic parameter configuration table module according to the power grid noise spectrum characteristics;

[0066] S4. Output the communication parameter combination to complete the establishment of the adaptive communication link.

[0067] The present invention adopts the HPLC communication module, the dynamic parameter configuration table module, the intelligent matching algorithm module, and the feedback control module. The communication rate is increased by more than 30% (under the condition of the same packet error rate), the packet error rate in the narrowband interference scenario is reduced to less than 5%, the parameter configuration efficiency is increased by 50%, and the need for manual intervention is reduced. By constructing a deep coupling between the dynamic parameter configuration table and the HPLC hardware, the adaptive adjustment of communication parameters is realized, effectively solving the technical defects of the traditional HPLC communication system in the complex power grid environment, and significantly improving the reliability of communication and the data collection efficiency.
