The server includes, but is not limited to: a single server, a server cluster, a cloud server, or a cloud server cluster, etc.
[0046] Refer to Figure 1 As shown, it is a schematic flowchart of a radio frequency power supply ignition method provided by an embodiment of the present invention. In this embodiment, the radio frequency power supply ignition method includes the following steps S1 - S6:
[0047] S1. Obtain the radio frequency module in the radio frequency circuit, connect the output end of the radio frequency module to a preset directional coupler, and sense the radio frequency power intensity of the radio frequency module through the directional coupler to obtain an analog intensity signal. Among them, the radio frequency circuit includes a radio frequency module, a directional coupler, an analog-to-digital converter, a digital-to-analog converter, an MCU processor, and a high-speed switch.
[0048] It can be understood that the connection and working mode of the radio frequency circuit realize the precise monitoring, control, and adjustment of the output power of the radio frequency module. By working together with components such as the directional coupler, analog-to-digital converter, digital-to-analog converter, MCU processor, and high-speed switch, the radio frequency power intensity can be sensed in real time, converted into a digital signal for processing and calculation, and then through the conversion and output of the power control amount, the precise control of the output power of the radio frequency module can be achieved, ensuring the stable output of the radio frequency power, and the radio frequency power is controlled in the form of pulses through the high-speed switch for ignition, improving the success rate and efficiency of ignition, and ultimately achieving the effect of optimizing the performance of the radio frequency system and improving the stability and reliability of the system.
[0049] In the embodiments of the present invention, the radio frequency module refers to a device capable of generating radio frequency power signals. It is the power source of the entire radio frequency circuit, providing power support for subsequent signal processing and transmission. In this circuit, the role of the radio frequency module is to generate radio frequency power signals, and its output terminal is connected to a directional coupler. The directional coupler senses the radio frequency power intensity of the radio frequency module to obtain an analog intensity signal, providing a basis for subsequent analog-to-digital conversion and power control.
[0050] In the embodiments of the present invention, a directional coupler is a passive device widely used in radio frequency and microwave systems. It can couple the radio frequency power output by the radio frequency module to another transmission line in a certain proportion to achieve directional transmission and power monitoring of signals. A directional coupler usually has four ports: an input port, an output port, a coupling port, and an isolation port. When a signal is input from the input port, most of the signal will pass directly through the output port, and at the same time, a small part of the signal will be coupled to the coupling port for output, while the isolation port is usually connected to a matching load to achieve high isolation. The main technical indicators of a directional coupler include coupling degree, isolation degree, insertion loss, and bandwidth, etc. In a radio frequency circuit, a directional coupler is used to monitor the output power of the radio frequency module, providing a basis for subsequent power control and adjustment to ensure the stable and reliable operation of the radio frequency system.
[0051] S2. Convert the analog intensity signal into a digital signal through the analog-to-digital converter to obtain a digital intensity signal, and use the MCU processor to convert the digital intensity signal into radio frequency power. Among them, the PID control algorithm is included in the MCU processor.
[0052] In the embodiments of the present invention, an analog-to-digital converter (ADC) is an electronic device that converts an analog signal into a digital signal. It receives the analog intensity signal from the directional coupler and converts it into a digital signal, that is, a digital intensity signal, for the processor to calculate and control the radio frequency power. The analog-to-digital converter plays a key bridging role in the radio frequency circuit, converting the analog signal into a digital signal, thereby realizing precise monitoring and digital processing of the output power of the radio frequency power device, ensuring that the radio frequency system can operate stably and output the required power. The performance indicators of the analog-to-digital converter, such as resolution, accuracy, sampling rate, etc., directly affect the accuracy of power monitoring and the stability of the system.
[0053] In the embodiments of the present invention, in the radio frequency circuit, the MCU processor is the core control component, responsible for receiving and processing the digital intensity signal from the analog-to-digital converter. The MCU processor uses the internal PID control algorithm to analyze and calculate the signal to determine the power control amount required by the radio frequency module. The efficient operation and precise control of the MCU processor ensure the stable output and fast response of the radio frequency power, and it is the key component for the entire radio frequency system to achieve automatic and intelligent control.
[0054] Furthermore, the analog intensity signal is converted into a digital signal by an analog-to-digital converter to obtain a digital intensity signal, and the MCU processor including the PID control algorithm is used to convert the digital intensity signal into radio frequency power. This process realizes the precise digital control of the radio frequency power. The PID control algorithm can adjust the control quantity in real time according to the digital intensity signal to ensure the stability and accuracy of the radio frequency power output, effectively reduce errors and fluctuations, improve the response speed and adaptability of the system, and enable the radio frequency device to quickly and accurately adjust the power output under different working conditions to meet specific application requirements.
[0055] S3. Based on the PID control algorithm, the power control quantity required by the radio frequency module is calculated using the radio frequency power, and the power control quantity is converted into an analog signal through the digital-to-analog converter to obtain a power control analog signal.
[0056] It can be understood that based on the PID control algorithm, the power control quantity required by the radio frequency module is calculated using the radio frequency power, and the power control quantity is converted into an analog signal through the digital-to-analog converter. This process can realize the precise and stable control of the output power of the radio frequency module. The PID control algorithm will dynamically adjust the power control quantity according to the deviation between the actual radio frequency power and the target power to ensure that the output power of the radio frequency module quickly and accurately reaches the set value, effectively reduce power fluctuations and errors, improve the overall performance and stability of the radio frequency system, and enable it to maintain good output characteristics under different working conditions.
[0057] In the embodiment of the present invention, the digital-to-analog converter (DAC) is an electronic device that converts a digital signal into an analog signal. It receives the digital power control quantity from the processor and converts it into an analog signal, that is, a power control analog signal, for controlling the radio frequency module to output the set power. The digital-to-analog converter plays a key bridging role in the radio frequency circuit, converting the digital signal into an analog signal, thereby realizing the precise control of the output power of the radio frequency module and ensuring that the radio frequency system can stably output the required power. The performance indicators of the digital-to-analog converter, such as resolution, accuracy, linearity, etc., directly affect the accuracy of power control and the stability of the system.
[0058] In the embodiment of the present invention, the PID control algorithm is a feedback control algorithm widely used in control systems. It processes the error signal through three links: proportional (P), integral (I), and derivative (D) to achieve precise control of the system output. The proportional link adjusts the control quantity proportionally according to the size of the error, the integral link eliminates the steady-state error, and the derivative link predicts the change trend of the error and adjusts in advance. The three work together to make the system quickly respond and stably reach the set value, and is widely used in control fields such as temperature, pressure, and speed to ensure that the system output is consistent with the target value.
[0059] S4. Use the power control analog signal to control the radio frequency module to output a set power, and obtain the controlled radio frequency power.
[0060] It can be understood that using the power control analog signal to control the radio frequency module to output a set power can achieve precise and stable control of the output power of the radio frequency module, ensuring that the radio frequency module transmits signals according to the preset power level. This method enables the radio frequency system to quickly and accurately adjust the output power according to actual needs, effectively reducing power fluctuations and errors, improving the stability and reliability of the system, and meeting the strict requirements for radio frequency power in different application scenarios.
[0061] S5. Use a preset high-speed switch to control the controlled radio frequency power to be ignited in the form of pulses, and after successful ignition, control the radio frequency module to enter the normal output mode.
[0062] It can be understood that using a preset high-speed switch to ignite the controlled radio frequency power in the form of pulses and enter the normal output mode after successful ignition significantly improves the ignition efficiency and power control accuracy of the radio frequency system. The high-speed switch enables the radio frequency power to be instantaneously released in the form of pulses, ensuring quick and reliable ignition while reducing energy loss during the ignition process. After successful ignition, it quickly switches to the normal output mode, ensuring the stability and efficiency of the system in different working stages, enabling the radio frequency device to maintain good performance and reliability in various application scenarios.
[0063] In the embodiment of the present invention, the use of a preset high-speed switch to control the controlled radio frequency power to be ignited in the form of pulses and, after successful ignition, control the radio frequency module to enter the normal output mode includes:
[0064] When the high-speed switch is closed, output the controlled radio frequency power at power P1;
[0065] When the high-speed switch is opened, decrease the controlled radio frequency power to power P2 for output, repeat the above steps a preset number of times for ignition, and after successful ignition, control the radio frequency module to enter the normal output mode and output the controlled radio frequency power at power P1, where the power P1 is greater than a preset first reference power, the power P2 is less than a preset second reference power, and the preset second reference power is less than the preset first reference power.
[0066] In the embodiment of the present invention, the outputting the controlled radio frequency power at power P1 includes:
[0067] Send instructions to the MCU processor corresponding to the RF circuit through a preset human-machine interface or communication interface, and set the power value P1 and pulse parameters to obtain the power P1, where the pulse parameters include duty cycle, frequency, and number of attempts;
[0068] Through the MCU processor, turn off the continuous output mode of the RF module in the RF circuit, and activate the high-speed switch in the RF circuit to enter the pulse ignition mode;
[0069] Based on the power P1, combined with the current output power of the RF module, use a preset PID control algorithm to calculate the required digital control signal, obtain the adjusted digital signal, and convert the adjusted digital signal into an analog voltage signal through a digital-to-analog converter, and input it to the power control terminal of the RF module. Through the power control terminal, control the RF power to be output at the power P1.
[0070] Further, after using the preset high-speed switch to control the RF power to be ignited in the form of pulses, the method further includes:
[0071] If the ignition fails, automatically adjust the parameters of the controlled RF power and then perform an ignition attempt.
[0072] Further, the automatically adjusting the parameters of the controlled RF power and then performing an ignition attempt includes:
[0073] Obtain the power P1 and power P2 in the controlled RF power, and automatically increase the power P1 in the controlled RF power or increase the duty cycle in the controlled RF power to obtain the adjusted controlled RF power, and use the adjusted controlled RF power for ignition;
[0074] If the ignition fails, increase the pulse frequency of the adjusted controlled RF power to obtain the enhanced controlled RF power, and use the enhanced controlled RF power for ignition.
[0075] In the embodiment of the present invention, the using the preset high-speed switch to control the RF power to be ignited in the form of pulses includes:
[0076] Based on the preset pulse parameters, turn off the high-speed switch, and after the preset pulse parameters are satisfied, send a disconnection instruction to the high-speed switch, and repeat the above operations to form pulse ignition.
[0077] In the embodiment of the present invention, the automatically increasing the power P1 in the controlled RF power includes:
[0078] Increase the controlled RF power from the power P1 to 1.5 times the power P1 or 2 times the power P1.
[0079] In an embodiment of the present invention, a radio frequency module of a radio frequency circuit is obtained, and the radio frequency power intensity of the radio frequency module is sensed through a directional coupler to obtain an analog intensity signal; the analog intensity signal is converted into a digital signal through an analog-to-digital converter to obtain a digital intensity signal, and the MCU processor is used to convert the digital intensity signal into radio frequency power; based on the PID control algorithm, the power control amount required by the radio frequency module is calculated using the radio frequency power and converted into a power control analog signal; the power control analog signal is used to control the radio frequency module to output a set power to obtain a controlled radio frequency power; a high-speed switch is used to ignite the controlled radio frequency power in the form of a pulse, and after successful ignition, enter the normal output mode.
