Description

Technical Field

[0001] The present disclosure relates to the technical field of microwave debugging. Specifically, it relates to a microwave parameter automatic adjustment method and a microwave parameter automatic adjustment device that can automatically adjust microwave parameters. Background Art

[0002] An accelerator is a device that increases the speed or kinetic energy of charged particles and can be used in nuclear experiments, radioactive medicine, radiochemistry, the manufacture of radioactive isotopes, and non-destructive flaw detection, etc. The accelerator has a microwave system, which includes an accelerating tube and a magnetron, and is used to feed the generated radio frequency signal into the accelerating tube, and complete the acceleration of electrons in the accelerating tube to provide energy. At the same time, it provides a phase discrimination signal for an automatic frequency control device to make the operating frequency of the magnetron automatically track the resonant frequency of the accelerating tube, so as to obtain stable energy and maximum dose rate output.

The symbol " / " generally indicates an "or" relationship between the associated objects before and after.

[0038] In the present disclosure, unless otherwise clearly specified and defined, terms such as "connection" should be understood in a broad sense. For example, it may be an electrical connection or may be able to communicate with each other; it may be directly connected or indirectly connected through an intermediate medium.

These functional entities can be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0040] The following further elaborates on each step of the microwave parameter automatic adjustment method in this exemplary embodiment in conjunction with the accompanying drawings and embodiments.

[0041] Currently, in the related art, the process of debugging the accelerator microwave system is generally as follows:

[0042] The first step: After the accelerator emits beams, the operator observes the sampling amplitude of the incident wave (the microwave output by the magnetron) through an oscilloscope, then stops the beam, enters the machine room, and manually rotates the control knob of the attenuator. Emits beams again and observes the amplitude of the incident wave. Repeat this step until the amplitude of the incident wave meets the specified requirements. Use the same process to debug the amplitude of the reflected wave (accelerating tube) in the case of total reflection of the accelerator, and adjust the amplitude of the reflected wave to be the same as that of the incident wave.

[0043] The second step: After the accelerator emits beams, observe whether the combined wave signal of the incident wave and the reflected wave after passing through the phase discriminator is symmetric, and when the combined wave is at 0V, the accelerator dose rate reaches the maximum. If not, stop the accelerator beam, adjust the phase discriminator knob, emit beams again and observe until the requirements are met.

[0044] The technical defects of the above technical solutions include:

[0045] (1) Manually debugging the knob has low adjustment accuracy, and it is impossible to ensure that the incident wave, reflected wave, and combined wave fully meet the requirements. Moreover, long-term use of a microwave system with low debugging accuracy will cause a series of problems such as the abnormal operation of the accelerator automatic frequency control (AFC, Automatic Frequency Control) system and abnormal accelerator dose rate.

[0046] (2) Considering that the area where the accelerator is located is a radiation protection area, it is necessary to conduct patrol inspections and clear the field before each accelerator beam emission. Repeated entry and exit of personnel in the radiation protection area for operation is cumbersome, inefficient, and even poses a safety hazard.

[0047] To overcome the above technical defects, the embodiments of the present disclosure propose a microwave parameter automatic adjustment method and device. Next, the embodiments of the present disclosure will be described in conjunction with the accompanying drawings of the specification.

[0048] Figure 1 It is a schematic diagram of a microwave parameter automatic adjustment device provided by an embodiment of the present disclosure for automatically adjusting microwave parameters.

[0049] As Figure 1As shown, the microwave parameter automatic adjustment device 100 may include: a signal generation module 102, an adjustment mechanism 104, and a control module 106. Among them, the signal generation module 102 generates an incident wave and a reflected wave, and sends the incident wave and the reflected wave to the adjustment mechanism 104. The control module 106 acquires the incident wave and the reflected wave that are adjusted and output by the adjustment mechanism 104, executes the microwave parameter automatic adjustment method provided by the embodiments of the present disclosure, calculates the parameters of the incident wave and the reflected wave and the combined wave parameter, and automatically sends an adjustment instruction to the adjustment mechanism 104 according to the calculation result to control the adjustment mechanism 104 to adjust the microwave signal output by it.

[0050] Figure 2 It is a flowchart of a microwave parameter automatic adjustment method in an exemplary embodiment of the present disclosure. Figure 2 The method shown can be performed by Figure 1 the control module 106 shown.

[0051] Referring to Figure 2 , the microwave parameter automatic adjustment method may include:

[0052] Step S202, obtain a target amplitude, an incident wave, and a reflected wave in response to an incident wave amplitude modulation request.

[0053] Step S204, after automatically adjusting the amplitude of the incident wave to the target amplitude, automatically adjust the amplitude of the reflected wave to the target amplitude.

[0054] Step S206, obtain the combined wave of the incident wave and the reflected wave.

[0055] Step S208, automatically adjust the phase of the reflected wave so that the amplitude of the combined wave is within a preset range.

[0056] In one embodiment, the preset range of the amplitude of the combined wave may be, for example, [-100, +100], with the unit of mV. Among them, when the amplitude of the combined wave is 0, the adjustment effect of the microwave parameters is the best, and the dose rate of the accelerator is the largest.

[0057] In one embodiment, the incident wave and the reflected wave have the same period and the same waveform. For example, both the incident wave and the reflected wave are square waves, sine waves, or triangular waves.

[0058] Figure 2In the method of the illustrated embodiment, the incident wave amplitude modulation request can be controlled, for example, by the external control input control module 106. The external control methods include but are not limited to control methods such as buttons, knobs, virtual buttons, voice control, light control, program control, etc. The present disclosure does not impose special restrictions on this. By automatically controlling the adjustment mechanism in response to the incident wave amplitude modulation request to adjust the amplitudes of the incident wave and the reflected wave, and automatically adjusting the phase of the reflected wave so that the amplitude of the combined wave of the incident wave and the reflected wave is within a preset range, the adjustment efficiency and adjustment accuracy of microwave parameters can be improved, and the problems of low efficiency and insufficient adjustment accuracy in manually adjusting microwave parameters in the related art can be avoided.

[0059] Figure 3 It is a waveform schematic diagram of the microwave signal in the embodiment of the present disclosure.

[0060] As Figure 3 shown, the abscissa is time, the ordinate is amplitude. The incident wave 302, the reflected wave 304 and the combined wave 306 are all sine waves. By determining the amplitudes of the incident wave 302 and the reflected wave 304 at the target time point, the amplitude of the combined wave 306 at the target time point can be determined in real time, and then the waveform signal of the combined wave 306 within a period of time can be determined.

[0061] For example, taking any moment as the target time point, the amplitudes of the incident wave 302 and the reflected wave 304 at the target time point can be determined. The sum of the amplitudes of the incident wave 302 and the reflected wave 304 at this moment is used as the first value, and the difference between the amplitudes of the incident wave 302 and the reflected wave 304 at this moment is used as the second value. The difference between the first value and the second value is determined as the combined wave amplitude of the combined wave 306. Alternatively, using the function mapping relationship between the phase difference between the incident wave 302 and the reflected wave 304 and the combined wave amplitude, the combined wave amplitude of the combined wave 306 is determined. The present disclosure is not limited to the methods in the above embodiments, and other methods can also be used to determine the combined wave amplitude of the combined wave 306.

[0062] In one embodiment, the adjustment mechanism 104 may include a first attenuator, a second attenuator, and a phase discriminator.

[0063] Figure 4 It is a structural schematic diagram of the microwave parameter automatic adjustment device in an embodiment of the present disclosure.

[0064] As Figure 4As shown, the microwave parameter automatic adjustment device 400 may include: a signal generation module 402, an adjustment mechanism 404, and a control module 406. The adjustment mechanism 404 includes a first attenuator 4042, a second attenuator 4044, and a phase discriminator 4046. Among them, the output end of the signal generation module 402 is respectively connected to the input end IN1 of the first attenuator 4042 and the input end IN2 of the second attenuator 4044. The output end OUT1 of the first attenuator 4042 and the output end OUT2 of the second attenuator 4044 are connected to the input end OUT3 of the phase discriminator 4046. At the same time, the output end OUT1 of the first attenuator 4042, the output end OUT2 of the second attenuator 4044, and the output end OUT3 of the phase discriminator 4046 are connected to the input end of the control module 406. The output end of the control module 406 is respectively connected to the control end C1 of the first attenuator 4042, the control end C2 of the second attenuator 4044, and the control end C3 of the phase discriminator 4046.

[0065] In one embodiment, after the signal generation module 402 generates an incident wave and a reflected wave, it sends the incident wave to the first attenuator 4042 and the reflected wave to the second attenuator 4044. The control module 406 receives the incident wave output by the first attenuator 4042, determines whether the amplitude of the incident wave is within a preset range, and sends an incident wave amplitude adjustment instruction to the first attenuator 4042 based on the determination result to control the first attenuator 4042 to adjust the amplitude of the incident wave. Similarly, the control module 406 receives the reflected wave output by the second attenuator 4044, determines whether the amplitude of the reflected wave is within a preset range, and sends a reflected wave amplitude adjustment instruction to the second attenuator 4044 based on the determination result to control the second attenuator 4044 to adjust the amplitude of the reflected wave.

[0066] In one embodiment, the control ends of the first attenuator 4042, the second attenuator 4044, and the phase discriminator 4046 are all control knobs. The adjustment mechanism 406 may include: a first driving unit, a second driving unit, and a third driving unit. Among them, the first driving unit is used to receive the incident wave amplitude adjustment instruction sent by the control module 406 and drive the control knob of the first attenuator 4042 to rotate. The second driving unit is used to receive the reflected wave amplitude adjustment instruction sent by the control module 406 and drive the control knob of the second attenuator 4044 to rotate. The third driving unit is used to receive the phase adjustment instruction sent by the control module 406 and drive the control knob of the phase discriminator 4046 to rotate.

[0067] In one embodiment, the first driving unit includes a first driving motor, a first rotating gear, and a first connector connected in sequence. The control end of the first driving motor is connected to the control module 406, the output end of the first driving motor is connected to the first rotating gear, and the first rotating gear is connected to the control knob of the first attenuator 4042 through the first connector. The first driving motor responds to the incident wave amplitude modulation instruction sent by the control module 406, drives the first rotating gear to rotate, and drives the first connector to perform a transmission movement to control the rotation of the control knob of the first attenuator 4042.

[0068] In one embodiment, the second driving unit includes a second driving motor, a second rotating gear, and a second connector connected in sequence. The control end of the second driving motor is connected to the control module 406, the output end of the second driving motor is connected to the second rotating gear, and the second rotating gear is connected to the control knob of the second attenuator 4044 through the second connector. The second driving motor responds to the reflected wave amplitude modulation instruction sent by the control module 406, drives the second rotating gear to rotate, and drives the second connector to perform a transmission movement to control the rotation of the control knob of the second attenuator 4044.

[0069] In one embodiment, the third driving unit includes a third driving motor, a third rotating gear, and a third connector connected in sequence. The control end of the third driving motor is connected to the control module 406, the output end of the third driving motor is connected to the first rotating gear, and the first rotating gear is connected to the control knob of the phase discriminator 4046 through the third connector. The third driving motor responds to the phase modulation instruction sent by the control module 406, drives the third rotating gear to rotate, and drives the third connector to perform a transmission movement to control the rotation of the control knob of the phase discriminator 4046.

[0070] In one embodiment, the above-mentioned connector may include an electrical connector and a traction member. Among them, the electrical connector may be, for example, a connector, a plug, and a socket, but is not limited thereto. The traction member may be, for example, a flexible link, a conveyor belt, or a wire rope, etc., but is not limited thereto.

[0071] Figure 5 It is a schematic structural diagram of a driving unit in an embodiment of the present disclosure.

[0072] Figure 5 The structure of the shown driving unit can be applied to the above-mentioned first driving unit, second driving unit, and third driving unit, for example.

[0073] Such as Figure 5As shown in the figure, the structure of the driving unit may include a driving motor 502, a plug-in connector 504, a transmission gear 506, a belt 508, and a control knob 510. The driving motor 502 is used to implement the functions of the above-mentioned first / second / third driving motors. The plug-in connector 504 and the belt 508 are used to implement the functions of the above-mentioned first / second / third connectors. The transmission gear 506 is used to implement the functions of the above-mentioned first / second / third rotating gears. Among them, the driving motor 502 is connected to the transmission gear 506 through the plug-in connector 504, and the transmission gear 506 and the control knob 510 form a transmission mechanism through the belt 508.

[0074] In one embodiment, the driving motor may include a DC motor and a stepper motor, but is not limited thereto.

[0075] The belt 508 is sleeved on the transmission gear 506 and the control knob 510. When the driving motor 502 works, it drives the transmission gear 506 to rotate, and then drives the control knob 510 to rotate through the belt 508. Therefore, by changing the driving speed, driving time, and driving direction of the driving motor 502, the rotation angle and rotation direction of the control knob 510 can be changed.

[0076] In one embodiment, the driving motor may be, for example, an L298N driver. The main control board of the driving motor may be, for example, an STM32F103VET6 single-chip microcomputer (referred to as the STM32 single-chip microcomputer). The control voltage of the driving motor is set through the I / O input signal of the main control board and sent to the L298N driver to control the operating state of the L298N driver. The L298N driver receives the output signal of the STM32 single-chip microcomputer and controls the operation of the driving motor according to the driving truth table. When both enable terminals of the L298N driver are at a high level, two driving motors can be controlled simultaneously, improving the control efficiency and stability of the driving motor.

[0077] The driving truth table of the driving motor is as follows:

[0078] Table 1 Driving Truth Table

[0079] ENA IN01 IN02 Drive motor status 0 X X Stop 1 0 0 Brake 1 0 1 Forward rotation 1 1 0 Reverse rotation 1 1 1 Brake

[0080] As shown in the above table, by setting the input levels IN01 and IN02 of the driving motor to determine the rotation direction of the driving motor and controlling the enable signal output by the enable terminal ENA, the state of the driving motor can be adjusted. When the enable signal is 0, the driving motor is in a free stop state. When the enable signal is 1 and both IN01 and IN02 are 0 or both IN01 and IN02 are 1, the driving motor is in a braking state. When the enable signal is 1, IN01 is 0, and IN02 is 1, the driving motor is in a forward rotation state. When the enable signal is 1, IN01 is 1, and IN02 is 0, the driving motor is in a reverse rotation state.

[0081] By using the driving unit provided in this embodiment, the microwave parameters of the microwave system can be simply, safely and fully automatically debugged, avoiding the frequent entry and exit of operators into special environments and overcoming the problem of cumbersome debugging processes. Since the whole process is automatically adjusted, the debugging efficiency and debugging accuracy can also be effectively improved.

[0082] Figure 6 is in one embodiment of the present disclosure Figure 2 The sub-flowchart of step S204 shown.

[0083] As Figure 6 shown, in one embodiment, step S204 may include:

[0084] Step S602, according to the first difference between the maximum amplitude of the incident wave in one period and the target amplitude, send an incident wave amplitude modulation instruction to the adjustment mechanism, and the incident wave amplitude modulation instruction includes the first difference and the adjustment direction of the amplitude of the incident wave.

[0085] Step S604, when the absolute value of the first difference is less than or equal to the preset error threshold, obtain the second difference between the maximum amplitude of the reflected wave in one period and the target amplitude, and send a reflected wave amplitude modulation instruction to the adjustment mechanism. The reflected wave amplitude modulation instruction includes the second difference and the amplitude adjustment direction of the reflected wave.

[0086] Step S606, when the absolute value of the second difference is less than or equal to the preset error threshold, determine that the amplitude adjustment of the incident wave and the reflected wave is completed.

[0087] Among them, the adjustment mechanism can be, for example, Figure 4 the structure shown, including a first attenuator and a second attenuator, for adjusting the amplitude of the incident wave and the amplitude of the reflected wave according to the incident wave amplitude modulation instruction and the reflected wave amplitude modulation instruction sent by the control module.

[0088] In one embodiment, the preset error threshold is a value greater than zero, for example, it can be 10 mV. In other embodiments of the present disclosure, the preset error threshold can also have other values, and the present disclosure does not make special restrictions on this.

[0089] When the waveforms of the incident wave and the reflected wave are sine waves, the method for judging the incident wave period and the reflected wave period can be, for example, to determine the incident wave period and the reflected wave period according to the time between consecutive wave peaks (or wave valleys) of the incident wave and the reflected wave. The amplitude adjustment direction can include, for example, a first direction (amplitude reduction direction) or a second direction (amplitude increase direction).

[0090] When the first difference is positive, it indicates that the first amplitude is greater than the target amplitude. At this time, the amplitude adjustment direction is the first direction (the amplitude reduction direction); when the first difference is negative, it indicates that the first amplitude is less than the target amplitude. At this time, the amplitude adjustment direction is the second direction (the amplitude increase direction). The corresponding relationship between the second amplitude and the adjustment direction is the same, and the present disclosure will not elaborate herein.

[0091] In one embodiment, when Figure 5 the amplitude adjustment direction of the incident wave is controlled by the rotation direction of the control knob shown, when the amplitude adjustment direction is the first direction and the amplitude adjustment amplitude is the first difference or the second difference, for example, the control knob can be rotated clockwise at a preset speed for the first time or the second time; similarly, when the amplitude adjustment direction is the second direction and the amplitude adjustment amplitude is the first difference or the second difference, for example, the control knob can be rotated counterclockwise at a preset speed for the first time or the second time. The corresponding relationships between the above preset speed, the first time, the second time, and the clockwise rotation direction and the counterclockwise rotation direction and the first direction and the second direction can be set by those skilled in the art according to the actual situation, and the present disclosure does not make special restrictions thereon.

[0092] Figure 7 is a sub - flowchart of Figure 2 step S206 in an embodiment of the present disclosure.

[0093] As Figure 7 shown, in one embodiment, step S206 may include:

[0094] Step S702, obtaining the first amplitude of the incident wave and the second amplitude of the reflected wave at the target time point.

[0095] Step S704, determining that the sum of the first amplitude and the second amplitude is the first value, and determining that the difference between the first amplitude and the second amplitude is the second value.

[0096] Step S706, determining the difference between the first value and the second value as the combined - wave amplitude of the combined wave at the target time point.

[0097] In one embodiment, when using Figure 4 the microwave parameter automatic adjustment device shown to execute Figure 7In the illustrated embodiment, the phase detector 4046 receives the incident wave output by the first attenuator 4042 and the reflected wave output by the second attenuator 4044, and obtains the sum of the amplitudes of the incident wave and the reflected wave (the first value) and the difference between the amplitudes of the incident wave and the reflected wave (the second value) based on the phase difference between the incident wave and the reflected wave, and sends the first value and the second value to the control module 406. The control module 406 determines the combined wave amplitude according to the difference between the first value and the second value, and determines whether the combined wave amplitude is within a preset range. If the combined wave amplitude is not within the preset range, the control module 406 sends a phase adjustment instruction to the phase detector 4046 to control the phase detector 4046 to adjust the phase of the reflected wave, so as to adjust the combined wave amplitude to within the preset range.

[0098] Figure 8 is a schematic diagram for adjusting the combined wave amplitude in an embodiment of the present disclosure.

[0099] Reference Figure 8 , the horizontal axis represents time, and the vertical axis represents amplitude. At time T1, the amplitudes of both the incident wave 802 and the reflected wave 804 are 0.8 mV, the sum of the amplitudes of the incident wave 802 and the reflected wave 804 is 1.6 mV, and the difference between the amplitudes of the incident wave 802 and the reflected wave 804 is 0 mV, then the amplitude of the combined wave 806 is 1.6 mV. At time T2, the amplitude of the incident wave 802 is 0.9 mV, the amplitude of the reflected wave 804 is 0 mV, the sum of the amplitudes of the incident wave 802 and the reflected wave 804 is 0.9 mV, and the difference between the amplitudes of the incident wave 802 and the reflected wave 804 is 0.9 mV, then the amplitude of the combined wave 806 is 0 mV.

[0100] Assume that the preset range of the combined wave amplitude is [-1 mV, +1 mV]. Then, the combined wave amplitude of 1.6 mV at time T1 exceeds the maximum value of this preset range, and it is necessary to adjust the phase of the reflected wave to reduce the combined wave amplitude.

[0101] Figure 9 is a sub-flowchart of Figure 2 step S208 shown in an embodiment of the present disclosure. Figure 9 The illustrated embodiment is used to adjust the phase of the reflected wave so that the combined wave amplitude is within a preset range.

[0102] As Figure 9 shown, in one embodiment, step S208 may include:

[0103] Step S902, if the amplitude of the combined wave at the first time point is greater than the maximum value of the preset range, determine the amplitude of the reflected wave at the second time point, and the second time point is the previous time point of the first time point.

[0104] Step S904, if the amplitude of the reflected wave at the second time point is greater than the amplitude of the reflected wave at the first time point, set the delay time of the reflected wave to the first time difference, where the first time difference is the difference between the first time point and the second time point.

[0105] Step S906, if the amplitude of the reflected wave at the second time point is less than the amplitude of the reflected wave at the first time point, set the delay time of the reflected wave to the second time difference, where the second time difference is the difference between the period of the reflected wave and the first time difference.

[0106] Step S908, send a phase adjustment command to the adjustment mechanism to adjust the phase of the reflected wave, where the phase adjustment command includes the delay time of the reflected wave.

[0107] Among them, the adjustment mechanism can be, for example Figure 1 or Figure 4 the structure shown, which is used to receive the phase adjustment command and adjust the phase of the reflected wave according to the phase adjustment command.

[0108] In the embodiments of the present disclosure, when the unit of the first time point is seconds, the second time point can be, for example, the previous second. The determination of the first time point and the second time point can be obtained according to the sampling frequency of the incident wave or the reflected wave by the adjustment mechanism or the control module, and the present disclosure does not limit this.

[0109] In one embodiment, if the amplitude of the combined wave at the first time point is greater than the maximum value within the preset range, it indicates that the amplitude of the reflected wave at this time point needs to be reduced. Therefore, judge the amplitude of the reflected wave at the previous time point to determine the phase adjustment direction of the reflected wave when reducing the amplitude of the reflected wave. If the amplitude of the reflected wave at the previous time point (the second time point) is larger than the current time point (the first time point), it means that the amplitude of the reflected wave gradually decreases in the current time period. At this time, the amplitude of the reflected wave at the next time point can be moved to the current time point (the first time point) to reduce the amplitude of the reflected wave at the current time point. That is, the purpose can be achieved by increasing the waveform delay time of the reflected wave by the first time difference (the difference between the first time point and the second time point). Similarly, if the amplitude of the combined wave at the first time point is less than the minimum value within the preset range, the amplitude of the reflected wave at this time point needs to be increased. If the amplitude of the reflected wave at the second time point is less than the amplitude of the reflected wave at the first time point, it means that the current amplitude of the reflected wave gradually increases. Then, the amplitude of the reflected wave at the first time point can also be increased by increasing the waveform delay time of the reflected wave by the above first time difference. After one adjustment, detection can be continued and adjustment can be continued until the amplitude of the combined wave is adjusted to within the preset range.

[0110] In addition, if the amplitude of the combined wave at the first time point is greater than the maximum value within the preset range, but the amplitude of the reflected wave at the second time point is less than the amplitude of the reflected wave at the first time point, it indicates that the amplitude of the reflected wave gradually increases during the current time period. Then, theoretically, the phase of the reflected wave needs to be advanced by the above-mentioned first time difference to reduce the amplitude of the reflected wave at the first time point. The purpose of advancing the reflected wave can be achieved by delaying the phase of the reflected wave by the second time difference (the difference between the period of the reflected wave and the above-mentioned first time difference). Similarly, if the amplitude of the combined wave at the first time point is less than the minimum value within the preset range, but the amplitude of the reflected wave at the second time point is greater than the amplitude of the reflected wave at the first time point, the purpose of advancing the reflected wave can be achieved by delaying the phase of the reflected wave by the above-mentioned second time difference.

[0111] In one embodiment, Figure 1 or Figure 4 the control module can also send a speed regulation instruction in response to a speed regulation request to control the running speed of the adjustment mechanism. The speed regulation request can be transmitted to the control module, for example, in the same way as the incident wave amplitude modulation request. The control module sends a speed regulation instruction to the drive unit in response to the speed regulation request. When the drive unit is implemented by the Figure 5 shown structure, the drive unit can control the rotation speed of the transmission gear according to the speed regulation instruction to change the rotation speed of the control knob connected to the transmission gear by a belt, thereby adjusting the rotation speed of the control knob. Adaptively, the time required for the first attenuator and the second attenuator to adjust the amplitude by the first difference and the second difference needs to be recalculated according to the adjusted rotation speed of the control knob.

[0112] Through the microwave parameter automatic adjustment method provided by the embodiments of the present disclosure, the flexibility and automation degree of parameter debugging can be improved, and the adjustment efficiency of the microwave system can be enhanced.

[0113] Figure 10 is a schematic diagram of a microwave parameter adjustment device provided by the embodiments of the present disclosure. Figure 10 The shown device can execute the functions of the control module in the above embodiments through a human-machine interaction interface.

[0114] As Figure 10 shown, the structure 1000 of the microwave parameter adjustment device includes: a signal generation module 1002, an adjustment mechanism 1004, and a human-machine interaction interface 1006. The signal generation module 1002 generates an incident wave and a reflected wave, and sends the incident wave and the reflected wave to the human-machine interaction interface 1006 and the adjustment mechanism 1004, so that the human-machine interaction interface 1006 calculates the incident wave and the reflected wave according to the adjustment instruction sent manually, and controls the adjustment mechanism 1004 to adjust the microwave parameters according to the calculation result.

[0115] Figure 11 is a schematic diagram of the structure of a microwave parameter adjustment device in one embodiment.Figure 11 The device shown can achieve the function of microwave parameter adjustment through convenient manual operation.

[0116] As Figure 11 shown, the microwave parameter adjustment device 1100 may include: a signal generation module 1102, an adjustment mechanism 1104, and a human-machine interface 1106. Among them, the adjustment mechanism 1104 includes a first attenuator 11042, a second attenuator 11044, and a phase discriminator 11046.

[0117] The output end of the signal generation module 1102 is respectively connected to the input end IN02 of the first attenuator 11042 and the input end IN04 of the second attenuator 11044. The output end OUT02 of the first attenuator 11042 and the output end OUT04 of the second attenuator 11044 are connected to the input end of the phase discriminator 11046. The output end OUT02 of the first attenuator 11042, the output end OUT04 of the second attenuator 11044, and the output end OUT06 of the phase discriminator 11046 are connected to the input end of the human-machine interface 1106. The output end of the human-machine interface 1106 is respectively connected to the control end C02 of the first attenuator 11042, the control end C04 of the second attenuator 11044, and the control end C06 of the phase discriminator 11046.

[0118] In one embodiment, the signal generation module 1102 sends the generated incident wave to the first attenuator 11042. The first attenuator 11042 sends the incident wave to the human-machine interface 1106, and the human-machine interface 1106 displays the amplitude of the incident wave so that the operator can determine whether the amplitude of the incident wave meets the preset range. If the operator determines that the amplitude of the incident wave meets the preset range, the amplitude of the incident wave is not adjusted. If the operator determines that the amplitude of the incident wave does not meet the preset range, the operator sends an incident wave amplitude adjustment instruction to the first attenuator 11042 through the human-machine interface 1106 to control the first attenuator 11042 to adjust the amplitude of the incident wave, and sends the adjusted incident wave to the human-machine interface 1106, and the human-machine interface 1106 displays the amplitude of the adjusted incident wave. The control process of the human-machine interface 1106 for the second attenuator 11044 and the phase discriminator 11046 is the same, and the present disclosure will not elaborate herein.

[0119] In one embodiment, when a connection fault occurs between the first attenuator 11042 and the human-machine interface 1106, the operator can disconnect the connection between the second attenuator 11044 and the phase discriminator 11046, so that the phase discriminator 11046 only receives the incident wave. At this time, the output result of the phase discriminator 11046 facing the human-machine interface 1106 is the incident wave. When a connection fault occurs between the second attenuator 11044 and the human-machine interface 1106, the operator can disconnect the connection between the first attenuator 11044 and the phase discriminator 11046, so that the phase discriminator 11046 only receives the reflected wave. At this time, the output result of the phase discriminator 11046 facing the human-machine interface 1106 is the reflected wave.

[0120] In one embodiment, the human-machine interface 1106 may include, for example, a host computer, an electric control box, and an oscilloscope.

[0121] Through the microwave parameter adjustment device provided in this embodiment, the steps of the operator repeatedly entering the machine room to manually rotate the control knobs of the attenuator or the phase discriminator can be omitted, the debugging process can be simplified, and the debugging efficiency can be improved.

[0122] Figure 12 It is a schematic diagram of the hardware configuration of the microwave parameter adjustment device in an embodiment of the present disclosure. Figure 12 The shown device can not only realize the automatic adjustment of microwave parameters, but also realize the manual operation adjustment of microwave parameters.

[0123] As Figure 12 As shown, the microwave parameter adjustment device 1200 may include: a signal generation module 1202, an adjustment mechanism 1204, and a human-machine interface 1206. The human-machine interface 1206 includes a host computer 12062, an electric control box 12064, and an oscilloscope 12066. Among them, the host computer 12062, the electric control box 12064, and the oscilloscope 12066 are used to implement the functions of the above-mentioned human-machine interface 1206. The host computer 12062 receives the incident wave and the reflected wave generated by the signal generation module 1202, and sends the amplitude data of the incident wave and the reflected wave to the oscilloscope 12046 through the communication method of TCP (Transmission Control Protocol), so as to obtain the calculation result of the oscilloscope 12066 calculating the amplitude data of the incident wave and the reflected wave. According to the calculation result and the RS232 (also known as EIA RS-232, which is one of the common serial communication interface standards) protocol, signal interaction with the electric control box 12064 is realized, and the electric control box 12064 is electrically connected to the adjustment mechanism 1204 through an RG58 coaxial cable. The host computer 12062 can further control the adjustment process of the adjustment mechanism through the electric control box 12064.

[0124] In one embodiment, the host computer 12062 includes a host computer system, which can be constructed through various development environments. For example, it can be a C language development environment, a BASIC development environment, and a Labview (Laboratory Virtual Instrument Engineering Workbench) development environment, but not limited thereto.

[0125] In one embodiment, the adjusting mechanism 1204 can be, for example, Figure 5 the structure shown. By changing the voltage signal of the driving motor, the driving direction of the transmission gear and the belt can be changed, and then the rotation direction of the control knob can be adjusted to adjust the value of the microwave parameter.

[0126] In one embodiment, the electric control box 12064 can include an STM32 single-chip microcomputer, an L298N driver board, a DC power supply, and BNC (Bayonet Nut Connector) socket components. Among them, the main control board of the STM32 single-chip microcomputer (such as Cortex-M3) can perform complex calculations and controls on the microwave parameters of the microwave system. The main control board communicates with the host computer through the RS232 protocol. According to the received amplitude modulation instruction of the incident wave or the amplitude modulation instruction of the reflected wave sent by the host computer, it outputs the enable signal of the GPIO port and the PWM (Pulse Width Modulation) pulse signal to the L298N driver board to control the operation of the L298N driver board, and sends the feedback information of the completion of the action of the received L298N driver board to the host computer system.

[0127] In one embodiment, part of the single-chip microcomputer control program is as follows:

[0128]

[0129]

[0130] Figure 13 It is a schematic diagram of the human-computer interaction interface in an embodiment of the present disclosure.

[0131] As Figure 13 shown, the human-computer interaction interface 1300 can include: an oscilloscope selection panel 1302, a single-chip microcomputer selection panel 1304, a mode switching panel 1306, a waveform data display interface 1308, a manual button 1310, a microwave value display interface 1312, a speed gear 1314, a microwave amplitude judgment interface 1316, and a feedback interface 1318.

[0132] In Figure 12 the hardware configuration environment shown, the functions of the human-computer interaction interface 1300 are as follows:

[0133] 1. Based on the RS232 protocol, serial communication is carried out between the STM32 single-chip microcomputer and the signals received by the single-chip microcomputer selection panel 1304, and adjustment instructions such as incident wave amplitude modulation instructions, reflected wave amplitude modulation instructions, phase modulation instructions, and speed regulation instructions can be transmitted and received at high speed.

[0134] 2. Based on TCP communication, interaction is completed between the oscilloscope selection panel 1302 and the oscilloscope, and real-time responses to incident wave amplitude modulation requests and reflected wave amplitude modulation requests are made to read microwave parameters, and the microwave parameters are sent to the waveform data display interface 1308 and the microwave value display interface 1312.

[0135] 3. The request to start the automatic mode is received through the mode switching panel 1306. In the automatic mode, microwave parameters are automatically calculated, and the calculation results are sent to the waveform data display interface 1308, the microwave value display interface 1312, and the microwave amplitude judgment interface 1316, and the feedback information corresponding to the calculation results is sent to the feedback interface 1318.

[0136] 4. The request to start the manual mode is received through the mode switching panel 1306. In the manual mode, the oscilloscope selection panel 1302, the single-chip microcomputer selection panel 1304, the manual button 1310, and the speed gear 1314 provide an interactive interface for operators to manually adjust microwave parameters, and the adjustment results of the microwave parameters are also displayed to the operators through the waveform data display interface 1308, the microwave value display interface 1312, the microwave amplitude judgment interface 1316, and the feedback interface 1318.

[0137] In one embodiment, the waveform data display interface 1308 is used to display the microwave waveform generated by the microwave parameters in real time, and the microwave value display interface 1312 is used to display the microwave amplitude.

[0138] In one embodiment, the feedback interface 1318 includes an indicator light, which is used to read the feedback information after the single action of the single-chip microcomputer is completed, and the feedback information is displayed through the color of the indicator light. For example, after the single action of the single-chip microcomputer is completed, if the microwave amplitude meets the preset range, the feedback information that the debugging has been completed is displayed by the green light of the indicator light, but it is not limited to this.

[0139] In one embodiment, the speed gear 1314 is used to adjust the single action speed.

[0140] In one embodiment, the manual button 1310 is used to complete different single actions, and the single actions include microwave decrease, microwave increase, microwave minute, microwave large, combined wave left shift, combined wave right shift, combined wave micro left, and combined wave micro right, but it is not limited to this.

[0141] Figure 14 This is a method for adjusting microwave parameters in an embodiment of the present disclosure. This method can be performed byFigure 13 executed by the shown human - machine interaction interface.

[0142] Before executing Figure 14 the shown microwave parameter adjustment method, the operator installs the transmission mechanism, connects and fixes the transmission mechanism to the variable attenuator and the phase discriminator to complete the installation of the adjustment mechanism, uses a BNC cable to connect the adjustment mechanism to the electronic control box, and connects the upper computer to the electronic control box and the oscilloscope respectively. Next, the operator powers on each device, configures the oscilloscope port, sets parameters and the single - chip communication port, and clicks the run button to start the program. If the program starts abnormally, check whether the devices, wiring and related settings are abnormal. If the program starts normally, the human - machine interaction interface executes the following process:

[0143] Step S1402, receive a start request.

[0144] Step S1404, determine whether the received start request is a request to start the automatic mode. If so, go to step S1406; if not, go to step S1412.

[0146] Step S1408, determine whether the microwave parameter meets the preset range. If so, execute step S1420; if not, execute step S1410.

[0147] Step S1410, automatically adjust the microwave parameter: calculate the microwave parameter, send a single - action instruction to the electronic control box according to the calculation result to control the electronic control box to drive the adjustment mechanism according to the single - action instruction, and feedback the information of the adjustment mechanism's completed action to the upper computer, and repeat this process continuously until the debugging result of the microwave parameter meets the requirements.

[0148] Step S1412, start the manual mode.

[0149] Step S1414, respond to the electrical signal of the microwave parameter to generate the microwave waveform of the microwave parameter.

[0150] Step S1416, display the microwave waveform to the operator.

[0151] Step S1418, receive the single - action instruction sent by the operator, drive the adjustment mechanism according to the single - action instruction, and feedback the information of the adjustment mechanism's completed action received to the operator through the feedback interface.

[0152] Step S1420, debugging completed.

[0153] Through the microwave parameter adjustment method of the embodiments of the present disclosure, the microwave parameters can be debugged in both automatic mode and manual mode with only convenient operation, reducing the adjustment range of the microwave amplitude corresponding to a single action instruction and improving the debugging accuracy.
