[0053] Referring to Figure 1 As shown, it is a schematic flowchart of a high-speed data acquisition method based on a radio frequency power supply provided by an embodiment of the present invention. In this embodiment, the high-speed data acquisition method based on the radio frequency power supply includes the following steps S1-S5:

[0054] S1. Based on the output power set by the user, at the output end of the radio frequency power supply, use a directional coupling device to obtain the reflection coefficient of the radio frequency signal in the radio frequency power supply, and calculate the incident power and reflection power of the radio frequency power supply according to the reflection coefficient to obtain the radio frequency incident power and the radio frequency reflection power.

[0055] It can be understood that by using a directional coupling device to monitor the output signal of the radio frequency power supply, the incident power and reflection power are calculated by obtaining the reflection coefficient, so as to realize the accurate monitoring and evaluation of the output characteristics of the radio frequency power supply, facilitate optimizing system matching and ensuring the effective utilization of radio frequency energy.

[0056] In the embodiment of the present invention, the directional coupler is a device for coupling microwave or radio frequency signals on a transmission line. It can couple a part of the signal in the transmission line to another transmission line in a specific direction, and has little influence on the signal transmission on the main transmission line. It is often used in scenarios such as signal monitoring and power distribution, and is widely used in fields such as communication systems and radio frequency circuits.

[0057] In the embodiment of the present invention, the step of using a directional coupling device to obtain the reflection coefficient of the radio frequency signal in the radio frequency power supply, and calculating the incident power and reflection power of the radio frequency power supply according to the reflection coefficient to obtain the radio frequency incident power and the radio frequency reflection power includes:

[0058] Obtain the parameters of the directional coupler, and use a preset vector network analyzer to measure the scattering parameters of the directional coupler to obtain the coupler scattering parameters;

[0059] Obtain the incident port and reflection port of the directional coupler to obtain the coupler incident port and the coupler reflection port, and collect the vector voltages of the coupler incident port and the coupler reflection port to obtain the coupler incident voltage and the coupler reflection voltage;

[0060] Normalize the coupler incident voltage and the coupler reflection voltage to obtain the normalized incident power wave and the normalized reflection power wave;

[0061] Based on the coupler scattering parameters, the normalized incident power wave and the normalized reflection power wave, calculate the reflection coefficient in the RF power supply, and calculate the incident power and the reflection power according to the reflection coefficient of the RF power supply to obtain the RF incident power and the RF reflection power.

[0062] Specifically, the vector network analyzer is a precision instrument used to measure and analyze the network parameters of RF and microwave devices and systems. By measuring the amplitude and phase information of signals, it can determine the scattering parameters of the measured network, thereby evaluating the transmission and reflection characteristics of the device, and is widely used in fields such as communication and microwave. It is a key test device in the RF and microwave fields.

[0063] Furthermore, through the directional coupling device and related measurement equipment and steps, obtaining the incident power and reflection power of the RF signal in the RF power supply and based on this obtaining the RF analog signal process can accurately measure the incident and reflection powers of the RF signal, and further provide a basis for obtaining an accurate RF analog signal, which helps to conduct a detailed analysis and accurate evaluation of the output signal characteristics of the RF power supply, so as to better optimize the performance of the RF system.

[0064] Furthermore, the normalization of the coupler incident voltage and the coupler reflection voltage to obtain the normalized incident power wave and the normalized reflection power wave includes:

[0065] Obtain the characteristic impedance of the directional coupler to obtain the coupler characteristic impedance, and obtain the coupler voltage based on the coupler incident voltage and the coupler reflection voltage;

[0066] Calculate the current of the coupler based on the coupler voltage and the coupler characteristic impedance to obtain the coupler current;

[0067] Based on the coupler voltage, the coupler current and the preset transmission line impedance, calculate the normalized incident power wave and the normalized reflection power wave;

[0068] Among them, the formulas for calculating the normalized incident power wave and the normalized reflection power wave are as follows:

[0069]

[0070] Among them, a represents the normalized incident power wave, b represents the normalized reflected power wave, v represents the coupler voltage, z0 represents the transmission line impedance, and I represents the coupler current.

[0071] In the embodiments of the present invention, the transmission line impedance refers to the resistance characteristic presented by the internal structure of the coupler to signal transmission during the signal transmission process. It affects the transmission efficiency and matching of signals between the coupler ports. Usually, it needs to be accurately calculated and matched according to specific application scenarios and design requirements to ensure the effective transmission of signals and the minimum reflection loss.

[0072] S2. Obtain a radio frequency analog signal according to the incident power and the reflected power, and use a preset digital-to-analog converter to convert the radio frequency analog signal into a digital signal to obtain a radio frequency digital signal.

[0073] It can be understood that the process of converting a radio frequency signal from an analog form to a digital form can convert the analog characteristics of the radio frequency signal (such as incident power and reflected power) into digital signals, which is convenient for subsequent digital processing, analysis, and storage, so as to more effectively utilize the radio frequency signal information in a digital system.

[0074] In the embodiments of the present invention, the digital-to-analog converter (DAC) is an electronic device or circuit used to convert a digital signal into a corresponding analog signal, playing a bridging role between a digital system and an analog system. It can convert discrete digital quantities (such as binary codes) into continuously varying analog voltage or current signals. Digital-to-analog converters are widely used in fields such as audio, video, communication, and control. For example, in an audio system, a digital audio file is converted into an analog signal to drive a speaker to play sound.

[0075] S3. Obtain the incident power data and the reflected power data in the radio frequency digital signal, and based on the incident power data and the reflected power data, use a preset FPGA for calculation to obtain the radio frequency reflectivity of the radio frequency power supply.

[0076] It can be understood that extracting the incident power data and the reflected power data from the radio frequency digital signal and using the FPGA for calculation to obtain the radio frequency reflectivity can quickly and accurately calculate the radio frequency reflectivity, thereby evaluating the performance of the radio frequency system and the signal transmission quality.

[0077] Furthermore, the PGA (Field Programmable Gate Array) is a programmable electronic component. With its powerful parallel processing ability and programmability, it can quickly and efficiently calculate the incident power data and reflected power data in the acquired RF digital signal, thereby obtaining the RF reflectivity of the RF power supply. The FPGA can perform real-time processing and analysis of the data according to the preset algorithm and logic, provide accurate calculation results, and provide key parameters for evaluating the performance of the RF system.

[0078] In the embodiment of the present invention, after obtaining the RF reflectivity of the RF power supply, the RF reflectivity can be compared with the reflection coefficient of the RF signal in the RF power supply. If the error value between the two exceeds 2%, the reflection coefficient of the RF signal in the RF power supply is re-acquired by using the directional coupling device, and subsequent operations are performed.

[0079] In another embodiment of the present invention, at the FPGA end, a gigabit Ethernet module can also be added to transmit real-time data to the PC end. The gigabit Ethernet transmission rate can reach gigabits per second, so the real-time data such as power, impedance, and frequency at the FPGA end can be completely sent to the PC end.

[0080] S4. Calculate the load impedance of the RF power supply based on the RF reflectivity, and obtain the time characteristics of the load impedance to obtain the real-time load impedance.

[0081] In the embodiment of the present invention, the process of calculating the load impedance of the RF power supply based on the RF reflectivity and obtaining its time characteristics to obtain the real-time load impedance can dynamically and accurately determine the impedance situation of the load of the RF power supply, provide key data support for the impedance matching and optimization of the RF system, and help improve the RF energy transmission efficiency and system stability.

[0082] Furthermore, the real-time load impedance refers to the characteristic that the impedance value of the load changes dynamically with time in the RF system. It reflects the degree of obstruction of the load to the RF signal at different time points and is an important parameter for evaluating the performance of the RF system and the signal transmission quality. By obtaining the real-time load impedance, the change situation of the load can be understood in a timely manner, providing a basis for the impedance matching and optimization of the RF system, thereby improving the transmission efficiency of RF energy and the stability of the system.

[0083] In the embodiment of the present invention, calculating the load impedance of the RF power supply based on the RF reflectivity includes:

[0084] Obtain the characteristic impedance of the circuit where the RF power supply is located to obtain the transmission line impedance, and calculate the load impedance of the RF power supply based on the RF reflectivity and the transmission line impedance;

[0085] Among them, the calculation formula for calculating the load impedance of the RF power supply based on the RF reflectivity and the transmission line impedance is as follows:

[0086] r = z0 * (1 + k) / (1 - k)

[0087] Among them, z0 is the transmission line impedance, and k is the RF reflectivity.

[0088] In the embodiment of the present invention, the transmission line impedance is usually 50Ω.

[0089] S5. Adjust the output power of the RF power supply based on the real-time load impedance, and obtain the adjustment data of the RF power supply to obtain RF adjustment data, where the RF adjustment data includes power adjustment data, impedance adjustment data, and frequency adjustment data of the RF power supply.

[0090] It can be understood that the process of adjusting the output power of the RF power supply according to the real-time load impedance and obtaining the adjusted data to obtain the RF adjustment data can realize the dynamic optimization of the output power of the RF power supply to adapt to the change of the load impedance, thereby improving the performance and stability of the RF system, ensuring the effective transmission of RF energy, and at the same time, by obtaining the adjustment data, it is convenient to monitor and analyze the working state of the RF power supply.

[0091] In the embodiment of the present invention, the adjusting the output power of the RF power supply based on the real-time load impedance and obtaining the adjustment data of the RF power supply to obtain the RF adjustment data includes:

[0092] Obtain the impedance set value, and calculate the error between the real-time load impedance and the impedance set value to obtain the impedance error;

[0093] Calculate the proportional, integral, and differential of the impedance error to obtain the impedance proportional, impedance integral, and impedance differential;

[0094] Adjust the output power of the RF power supply according to the impedance proportional, impedance integral, and impedance differential, and collect the output power, input voltage, current, working frequency, and real-time load impedance during the adjustment process of the RF power supply to obtain the RF adjustment data.

[0095] Further, protect the RF adjustment data according to the preset RF protection conditions to obtain the RF protection data.

[0096] Further, after adjusting the output power of the RF power supply based on the real-time load impedance and obtaining the adjustment data of the RF power supply to obtain the RF adjustment data, the method further includes:

[0097] Screen the radio frequency adjustment data according to preset radio frequency protection conditions to obtain screened data, and store the screened data in a preset database.

[0098] In an embodiment of the present invention, after adjusting the output power of the radio frequency power supply based on the real-time load impedance and obtaining the adjustment data of the radio frequency power supply to obtain radio frequency adjustment data, the method further includes screening the radio frequency adjustment data according to preset radio frequency protection conditions. According to different setting conditions, data is selectively saved. For example, the setting conditions are: start saving data when the power is less than 100W, and end saving data when the power is less than 10W.
