Description

Technical Field

[0001] The present invention relates to the field of power communication technology, and in particular to a power carrier time-frequency value recording platform based on time-frequency coding. Background Art

[0002] The power carrier time-frequency value refers to the time and frequency characteristics of the signal transmitted through the power line. Power carrier communication is a technology that uses power lines as a transmission medium for data transmission. Its core lies in the precise control and management of the time and frequency of the signal.

[0003] The significance of power carrier time-frequency value recording is to provide detailed power consumption data, help users better manage power consumption, and contribute to the optimization and improvement of the power system; power carrier time-frequency value recording can record power consumption and load information in real time, and provide users with more detailed power consumption data. This helps users to better manage power consumption, avoid unnecessary waste, and improve power efficiency; by recording and analyzing power and load data, future power demand can be predicted, so as to reasonably arrange power grid operation and power distribution. This helps to improve the stability and reliability of the power system and reduce power outages and power shortages;

[0004] In addition, power carrier technology can also realize remote monitoring and control of electricity meters, timely discover and deal with problems in electricity use, such as leakage, electricity theft and other abnormal situations, to ensure safe electricity use; power carrier technology uses existing power lines for data transmission, without the need to lay additional communication lines, reducing costs and improving the economy and practicality of the system. The core function of power carrier time and frequency value recording is to ensure the accurate synchronization of time and frequency in the power system, thereby improving the stability and reliability of the system. Through real-time remote tracing to the national atomic time standard, power carrier time and frequency value recording can ensure the accuracy, synchronization, safety and reliability of time and frequency values ​​in the fields of source, network, load and storage, thereby creating a model for the application of power time and frequency technology. Therefore, accurate recording of power carrier time and frequency values ​​is crucial.

[0005] For example, the application number is 201910964650.0, which is a high-speed power carrier acquisition method based on OFDM, including: the transmitting end loads the high-frequency signal carrying information onto the current; the current is transmitted through the power line; the modem at the receiving end acquires the high-frequency signal from the current, which includes: encoding the noisy signal into a frequency-modulated analytical signal through frequency modulation, and using the spikes in the time-frequency distribution of the frequency-modulated analytical signal as the instantaneous frequency estimate; the OFDM high-speed power carrier acquisition method provides a scheme for suppressing noise by eliminating time-frequency spikes, and a large number of simulation experiments have proved that it has a good suppression effect on background noise. However, the method still has certain defects;

[0006] During the signal acquisition process of the power carrier, the abnormal signal data in the power carrier cannot be recorded, so the abnormal signals in the power carrier transmission system cannot be checked and processed in time, making it impossible for the power carrier system to transmit power signals more efficiently and accurately.

[0007] Therefore, we proposed a power carrier time-frequency value recording platform based on time-frequency coding to solve the above problems. Summary of the invention
