Technical Field

[0001] The utility model relates to the field of radio frequency technology, in particular to a high-power medium-wave radio frequency power source remote controller. Background Art

[0002] Existing RF ion sources usually use inductive coupling to generate plasma. Specifically, a multi-turn RF antenna coil is placed outside a discharge chamber made of materials such as quartz and ceramics. When an RF current is passed through the antenna coil, an axial magnetic field is generated, which induces an electric field to accelerate electrons, which collide with neutral gases to ionize and generate plasma. In order to maintain a stable discharge, the RF power source needs to provide RF power current output for the RF ion source. In related technologies, the RF power source controls the output power by adjusting the amplitude of the output current.

[0003] However, the existing RF power source has certain limitations in controlling the output power. The output power is controlled by adjusting the output current amplitude, and its continuous adjustable range is limited, making it difficult to achieve fine control from zero to maximum output power. Utility Model Content

The system master control platform can send preset configuration data to the local power control unit. The local power control unit can convert the received configuration data into output power data in a digital signal format, and then adjust the power modules inside the radio frequency power source in turn to achieve the desired output power. Through the regulation of the output power data in the digital signal format, continuous adjustment from zero to maximum output power can be achieved, thereby realizing fine control of the output power.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model provides a high-power medium-wave radio frequency power source remote controller, which includes a system master control platform and a local power control unit arranged inside the radio frequency power source;

[0006] The system master control platform is connected to the radio frequency power source and is used to send preset configuration data to the local power control unit;

[0007] The local power control unit is used to convert the received configuration data into output power data in a digital signal format, and then adjust the power modules inside the RF power source in sequence until the output data of the RF power source reaches the output power data.

By regulating the output power data in the digital signal format, continuous adjustment from zero to maximum output power can be achieved, thereby realizing fine control of the output power.

[0009] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source internally includes: a frequency comparator and a RF blocking switch; the frequency comparator is connected to the RF blocking switch, and is used to compare the current frequency of the RF power source with a preset frequency. If the current frequency is not equal to the preset frequency, a first instruction is sent to the RF blocking switch; the RF blocking switch is used to receive the first instruction and shut down the RF power source when the first instruction is received.

[0010] By adopting the above embodiment, in the remote controller of the high-power medium-wave RF power source, the frequency comparator is used to detect whether the real-time output frequency of the RF power source is consistent with the preset frequency. If not, a shutdown command is sent to the RF blocking switch. After receiving the shutdown command from the frequency comparator, the RF blocking switch cuts off the output of the RF power source, thereby preventing RF power of the wrong frequency from being output. The output frequency of the RF power source can be monitored in real time, and the output can be quickly cut off when the frequency is abnormal, thereby preventing RF power of the wrong frequency from damaging the RF power source, thereby ensuring the safe and stable operation of the RF power source.

[0013] The tuning unit is used to adjust the current frequency of the radio frequency power source to the preset frequency after receiving the second instruction;

[0014] The radio frequency blocking switch is also used to turn on the radio frequency power source when receiving the third instruction.

[0015] By adopting the above-mentioned embodiment, in the remote controller of the high-power medium-wave RF power source, when the frequency comparator detects an output frequency error, the tuning unit can re-tune the output frequency of the RF power source and adjust it to the correct preset frequency, and can automatically correct the output frequency without completely cutting off the power source output, thereby improving the flexibility of the output.

[0016] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source further includes: a frequency monitoring unit connected to the frequency comparator, for monitoring the current frequency of the RF power source and sending the current frequency to the RF power source.

This can ensure that the frequency comparator grasps the real-time changes in the output frequency of the RF power source, thereby performing more accurate and timely frequency comparison, making the frequency monitoring and protection of the RF power source more reliable.

[0018] In some embodiments, in the high-power medium-wave radio frequency power source remote controller, the radio frequency power source further includes an output matching network;

[0019] The local power control unit is used to receive an impedance instruction, and when receiving the impedance instruction, controls the output impedance of the radio frequency power source to change to match the input impedance;

[0020] The output matching network is connected to the local power control unit and is used to receive the input impedance and the output impedance of the radio frequency power source, and if the input impedance does not match the output impedance, an impedance instruction is sent to the local power control unit.

[0021] By adopting the above embodiment, in the remote controller of the high-power medium-wave RF power source, the output matching network can detect the impedance value of the input end and the impedance value of the output end of the RF power source. When it is detected that the two do not match, an instruction to adjust the output impedance is sent to the local power control unit. After receiving the instruction, the local power control unit will adjust the output impedance of the RF power source to match the input impedance. The impedance matching situation can be monitored in real time, and the output impedance can be quickly adjusted when a mismatch occurs, so as to prevent power loss caused by impedance mismatch and ensure the maximization of the efficiency of the RF power source.

[0022] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source also includes: a remote control unit connected to the system master control platform and the local power control unit, used to receive the configuration data sent by the local power control unit, and send the configuration data to the system master control platform.

[0023] By adopting the above embodiment, in the high-power medium-wave RF power source remote controller, the remote control unit is used to remotely send the RF power source configuration data sent by the local power control unit, so as to realize remote monitoring and control of the RF power source output power and improve the flexibility and convenience of control.

[0024] In some embodiments, in the high-power medium-wave radio frequency power source remote controller, the radio frequency power source further includes: a power comparator and a power controller;

[0025] The power comparator is connected to the power controller and is used to compare the real-time working power with the output power data, and if the real-time working power is less than the output power data, send a fourth instruction to the power controller; if the real-time working power is equal to the output power data, send a fifth instruction to the power controller;

[0026] The power controller is used to receive a fourth instruction and a fifth instruction, and controls the power module inside the radio frequency power source to turn on when receiving the fourth instruction, and controls the power module inside the radio frequency power source to turn off when receiving the fifth instruction.

[0027] By adopting the above embodiment, in the remote controller of the high-power medium-wave RF power source, the power comparator detects the output power of the RF power source in real time and compares it with the preset output power data.

[0030] The fault information unit is connected to the power comparator and is used to receive the sixth instruction and send out fault information when receiving the sixth instruction.

[0031] By adopting the above embodiment, in the remote controller of the high-power medium-wave RF power source, when the power comparator detects that the output power of the RF power source is still less than the preset power value within the preset time, a fault instruction will be sent to the fault information unit. After receiving the instruction, the fault information unit will issue a fault alarm, and can monitor whether the output power of the RF power source is abnormal and cannot reach the expected output value, and give a fault prompt to prompt maintenance personnel to check the internal cause of the RF power source.

[0044] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0045] It should be noted that the RF ion source is an ion source that uses rarefied gas to discharge at high frequency to ionize the gas to produce plasma. In the oscillating electric field with amplitude generated by the RF power source, free electrons are accelerated and gain energy. If they collide with atoms (or molecules) in the gas to produce ionization, a balance is reached between the ionization and loss rates, thus forming a stable plasma. The RF ion source uses inductive coupling to produce plasma. The RF ion source is a discharge chamber (also made of materials with a very small recombination coefficient such as quartz and ceramics) with multiple turns of RF antenna coils (not in resonance mode). When RF current is passed through the antenna coil, an axial magnetic field is generated, which induces an electric field to accelerate electrons, and collides with neutral gas to produce plasma. Therefore, the function of a high-power RF power source is to provide RF power current for the RF ion source to produce plasma and maintain stable discharge.

[0046] The utility model provides a high-power medium-wave radio frequency power source remote controller, such as Figure 1 FIG. 2 is a schematic diagram showing the device connection of an embodiment of the utility model.

[0047] For ease of understanding, the following describes the high-power medium-wave radio frequency power source remote controller provided by this embodiment in combination with the above embodiments. Figure 1 , Figure 1 It is a schematic diagram of an embodiment of the utility model.

[0048] The utility model provides a high-power medium-wave radio frequency power source remote controller, such as Figure 2 As shown, it is a schematic diagram of an embodiment of the utility model. The high-power medium-wave RF power source remote controller includes a RF power source 1, a system master control platform 2, and a local power control unit 3. The system master control platform 2 is connected to the RF power source 1, and is used to send preset configuration data to the local power control unit 3. The local power control unit 3 converts the configuration data into output power data in a digital signal format, and then adjusts the power modules inside the RF power source in sequence until the output data of the RF power source reaches the output power data.

[0049] Specifically, the system master control platform 2 can be an industrial computer or a field bus controller, etc., connected to the RF power source 1 through a network or a serial port, and send the RF power source output power value preset by the user to the local power control unit 3. The local power control unit 3 uses a digital processing chip such as a DSP (digital signal processor) to convert the received power data into a digital quantized signal, and sequentially controls the power modules such as the amplifier, stabilizer, and filter inside the RF power source 1 to turn on or adjust the gain until the output power of the RF power source 1 stabilizes at the expected target value.

[0050] The local power control unit 3 is also connected to the touch screen, and the local power control unit 3 sends the output power data in the digital signal format to the touch screen, so that the touch screen can display the output power data in the digital signal format to the user.

[0051] For ease of understanding, the following further describes the high-power medium-wave radio frequency power source remote controller provided by this embodiment in combination with the above embodiments. Figure 2 , Figure 2 It is another schematic diagram of an embodiment of the utility model.

[0052] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes a frequency comparator 4, which is connected to the RF blocking switch 5 and is used to compare the current frequency of the RF power source 1 with the preset frequency. If the current frequency is not equal to the preset frequency, a first instruction is sent to the RF blocking switch 5; the RF blocking switch 5 is used to receive the first instruction and shut down the RF power source when the first instruction is received.

[0053] Specifically, the frequency comparator 4 can use a digital circuit chip to monitor the RF signal at the output end of the RF power source 1 in real time, read its frequency value, and compare the monitored frequency value with the preset frequency digital value stored locally. If there is a frequency deviation, a control signal is sent to the RF blocking switch 5. After receiving the signal, the RF blocking switch 5 uses a high-speed power switch tube and other devices to cut off the output of the RF power source 1 to achieve rapid shutdown, thereby avoiding the output of RF signals with incorrect frequency and protecting the RF power source 1.

[0054] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes a tuning unit 7, and the frequency comparator 4 is connected to the tuning unit 7, and is also used to send a second instruction to the tuning unit 7 when the current frequency is not equal to the preset frequency, and to send a third instruction to the RF blocking switch 5 when the current frequency is equal to the preset frequency. The tuning unit 7 is used to adjust the current frequency of the RF power source 1 to the preset frequency after receiving the second instruction, and the RF blocking switch 5 is also used to turn on the RF power source 1 when the third instruction is received.

[0055] Specifically, the tuning unit 7 can be a device such as a radio frequency resonant circuit. When the frequency comparator 4 detects a frequency error, it sends a control signal instruction to the tuning unit 7. The tuning unit 7 changes the resonant circuit parameters according to the control signal and readjusts the output frequency of the radio frequency power source 1 until the frequency is correct. In this way, the output frequency can be automatically corrected without completely cutting off the power source output, thereby improving output flexibility.

[0056] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes a frequency monitoring unit 8, which is connected to the frequency comparator 4 and is used to monitor the current frequency of the RF power source 1 and send the current frequency to the RF power source 1.

[0057] Specifically, the frequency monitoring unit 8 can use equipment such as a frequency detection coil to monitor the RF signal at the output end of the RF power source 1 in real time, obtain its frequency parameters, and feed back the monitored real-time frequency to the frequency comparator 4, so that the frequency comparator 4 can grasp the output frequency changes of the RF power source 1, thereby performing more accurate frequency comparison and improving monitoring accuracy.

[0058] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes an output matching network 6 and a local power control unit 3, which are used to receive impedance instructions. When the impedance instruction is received, the output impedance of the RF power source 1 is controlled to change to match the input impedance. The output matching network 6 is connected to the local power control unit 3, and is used to receive the input impedance and the output impedance of the RF power source 1. If the input impedance does not match the output impedance, the impedance instruction is sent to the local power control unit 3.

[0059] Specifically, the output matching network 6 can use an impedance measurement circuit to detect in real time the impedance values ​​of the input and output ends of the RF power source 1. When impedance mismatch is detected, a control signal is sent to the local power control unit 3, and the local power control unit 3 controls the variable capacitor or variable inductor inside the RF power source 1 according to the signal to adjust the output impedance to match the input impedance to prevent power loss caused by impedance mismatch.

[0060] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes a frequency monitoring unit 8, which is connected to the system master control platform 2 and the local power control unit 3, and is used to receive the configuration data sent by the local power control unit 3 and send the configuration data to the system master control platform 2.

[0061] Specifically, the frequency monitoring unit 8 can use various existing wireless communication modules, such as WIFI module, Bluetooth module, ZigBee module, etc., or wired network interface, such as Ethernet interface, serial port interface, etc. These communication modules or interfaces transmit the power setting value obtained by the local power control unit 3 to the system master control platform 2 which is far away. For example, in a transmitter station system, the local power control unit 3 is placed inside the transmitter, and the system master control platform 2 is placed in the monitoring room, and the two are remotely connected through the frequency monitoring unit 8. The system master control platform 2 displays the power value of the remote transmitter in real time through a human-computer interaction interface such as a display, which is convenient for operators to monitor and confirm whether the transmitter is working normally.

[0062] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes a power comparator 10 and a power controller 11. The power comparator 10 is connected to the power controller 11 and is used to compare the real-time working power with the output power data. If the real-time working power is less than the output power data, a fourth instruction is sent to the power controller 11. If the real-time working power is equal to the output power data, a fifth instruction is sent to the power controller 11. The power controller 11 is used to receive the fourth instruction and the fifth instruction. When the fourth instruction is received, the power module inside the RF power source 1 is controlled to be turned on. When the fifth instruction is received, the power module inside the RF power source 1 is controlled to be turned off.

[0063] Specifically, the fourth instruction and the fifth instruction are control signals generated by the power comparator 10 according to the comparison result and sent to the power controller 11. The fourth instruction indicates that the output power needs to be increased, and the fifth instruction indicates that the output power has reached the target value. The power controller 11 accurately turns on or off the power module inside the RF power source 1 according to the two instructions so that the output power is stable at a predetermined value. For example, the power module inside the RF power source 1 also includes components such as an RF interface board, a buffer amplifier, a pre-driver, an RF driver, and 224 RF power amplifier modules. The power comparator 10 uses a power detection circuit to detect the output power of the RF power source in real time, and compares the detected real-time power value with the target power value. If the detected power is lower than the target power, a control instruction to turn on the amplifier is sent to the power controller 11. If the detected power is equal to the target power, a shutdown control instruction is sent. The power controller 11 encodes and modulates the 224 RF power amplifier modules according to the control instruction fed back by the power comparator 10. If the output power is increased, the number of RF power amplifier modules turned on is increased, and vice versa, the number is reduced, thereby accurately adjusting the output power to reach the set value.

[0064] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes a fault information unit 12, and the power controller 11 is also used to send a sixth instruction to the fault information unit 12 if the real-time working power is less than the output power data within a preset time. The fault information unit 12 is connected to the power comparator 10 and is used to receive the sixth instruction. When the sixth instruction is received, a fault message is issued.

[0065] Specifically, if the real-time power fed back by the power comparator 10 is still lower than the target power within a certain period of time (e.g., 10 seconds), it indicates that the RF power source 1 is likely to be faulty and cannot reach the target power. At this time, the power controller 11 will determine that it is a fault condition and send a digital signal "2" as a fault signal to the fault information unit 12. After receiving the "2" signal, the fault information unit 12 can prompt the user through an audible and visual alarm, a human-computer interaction interface, etc., so as to timely check and locate the cause of the fault of the RF power source and avoid long-term erroneous output.

[0066] In some embodiments, in the high-power medium-wave RF power source remote controller, the RF power source 1 also includes an audio module 13, which is connected to the power controller 11 and is used to receive an audio signal from the outside, generate a control instruction based on the audio signal, and send the control instruction to the power controller 11.

[0067] Specifically, the audio module 13 includes an analog signal input board, an analog-to-digital converter, and a modulation encoder. The analog signal input board receives an external audio signal and superimposes a DC component on the audio signal to set the power level. The analog-to-digital converter converts the analog audio signal + DC into a 12-bit digital audio signal. The modulation encoder generates a coding control instruction for controlling the RF power amplifier module according to the digital audio signal and the required carrier and modulation level, such as integer control of a large step amplifier and fractional control of a binary amplifier to adjust the output power.

[0068] Finally, these coded control instructions are sent to the power controller 11, which modulates the start time and phase of the RF power amplifier according to the control instructions coded by the audio module, thereby realizing audio signal modulation and obtaining the required carrier power and instantaneous modulation effect.

[0069] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
