[0002] Existing ODU (Out Door Unit) products adopt a duplexer design. For existing duplexers, the operating frequency is generally non-adjustable, with poor flexibility and a narrow applicable range. For example, equipment manufacturers ship duplexers according to the required frequency bands of operators. However, each frequency band (such as 23G which ranges from 21.2G to 23.6G) is divided into several sub-bands. To ship in a timely manner, a certain amount of duplexer spare part inventory needs to be prepared for different sub-bands, which easily causes stagnation. Summary of the Invention

Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Without conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

[0039] In subsequent descriptions, suffixes such as "module", "component" or "unit" used to represent elements are only for the convenience of explaining the present invention and have no specific meaning of their own. Therefore, "module", "component" or "unit" can be used interchangeably.

[0040] It should be noted that although the functional modules are divided in the device schematic diagram and the logical sequence is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from the module division in the device or the sequence in the flowchart. Terms such as "first" and "second" in the specification, claims and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0041] Duplexer: It is a main accessory of a heterodyne duplex radio and a repeater. Its function is to isolate the transmitted and received signals to ensure that both reception and transmission can work properly at the same time. It is composed of two groups of band-pass filters with different frequencies to prevent the transmitted signal of the local machine from being transmitted to the receiver.

[0042] Existing ODU (Out Door Unit, outdoor unit) products adopt a duplexer design, and the duplexer is communicatively connected to the CPU (Central Processing Unit) of the ODU whole machine. For existing duplexers, the operating frequency is generally not adjustable, with poor flexibility and a narrow application range. For example, equipment manufacturers ship duplexers according to the required frequency bands of operators, but each frequency band (such as 23G is 21.2G - 23.6G) is divided into several sub-bands. In order to ship in time, a certain amount of duplexer spare parts inventory needs to be prepared for different sub-bands, which is likely to cause stagnation. In order to be able to cover a frequency band with one type of hardware inventory to reduce the spare parts inventory, it is necessary to develop a duplexer with adjustable frequency, which can adjust the operating frequency of the duplexer according to the on-site frequency requirements without replacing the hardware.

[0043] Based on the above, the present invention proposes a duplexer, a network device, a control method, an electronic device and a storage medium, which can realize the adjustable frequency of the duplexer, improve the flexibility and application range of the duplexer, and thus reduce the inventory pressure of manufacturers.

[0044] The technical solutions of the present invention will be described below in conjunction with specific embodiments.

[0045] In a first aspect, as Figure 1 shown, an embodiment of the present invention provides a duplexer, including:

[0046] a filter 100;

[0047] a dielectric tuning component 200;

[0048] a control module 300, the control module 300 is connected to the dielectric tuning component 200 and is configured to control the relative position of the dielectric tuning component 200 and the filter 100 to adjust the operating frequency of the duplexer.

[0049] In some embodiments, the relative position of the dielectric tuning component in the duplexer and the filter (the internal metal diaphragm) is one of the important factors determining the electrical performance (such as the operating frequency) of the duplexer. The control module in the duplexer can control the relative position of the dielectric tuning component and the filter, so as to achieve the purpose of adjusting the operating frequency of the duplexer. When a duplexer with multiple frequencies is required, the operating frequency of the duplexer can be adjusted by adjusting the relative position of the dielectric tuning component and the filter, improving the flexibility and application range of the duplexer, thereby avoiding the problem of needing to prepare a certain amount of duplexer spare part inventory for different sub-bands, and further reducing the inventory pressure on the manufacturer.

[0050] In some embodiments, the dielectric tuning component 200 is a dielectric tuning rod.

[0051] In some embodiments, as Figure 2 shown, the filter 100 includes a transmitting filter 110, a transmitting isolator 120, a transmitting waveguide port 130, a receiving filter 140, a receiving isolator 150, a receiving waveguide port 160, a circulator 170, a low-pass filter 180, and an antenna waveguide port 190. The transmitting isolator 120 and the receiving isolator 150 play a role in isolating and filtering signals. The circulator 170 is a three-port device, and the signals passing through the circulator are transmitted in the direction of the arrow of the circulator.

[0052] In some embodiments, the radio frequency signal from the CPU of the ODU enters the filter 100 through the transmitting waveguide port 130, passes through the transmitting isolator 120 (transmitted in the direction of the arrow), the transmitting filter 110, the circulator 170, and the low-pass filter 180, and reaches the antenna waveguide port 190; the radio frequency signal from the antenna waveguide port 190 passes through the low-pass filter 180, the circulator 170, the receiving filter 140, and the receiving isolator 150 (transmitted in the direction of the arrow), reaches the receiving waveguide port 160, and enters the CPU of the ODU, thereby realizing the band-pass filtering of the transmitting signal and the receiving signal.

[0053] In some embodiments, the control module 300 may adopt a TFCB (Tunable Filter Controlled Board). The TFCB can be directly assembled on the duplexer as an independent module and communicate with the CPU of the ODU through a 12Pin interface line to receive control signals from the CPU.

[0054] In some embodiments, as Figure 3 shown, the control module 300 includes:

[0055] A processing unit 310, which is configured to obtain a control signal and output a driving signal according to the control signal;

[0056] A driving unit 320, which is connected to the processing unit 310 and is configured to receive the driving signal and drive the motor unit according to the driving signal;

[0057] A motor unit 330, which is respectively connected to the driving unit 320 and the dielectric tuning component 200 and is configured to control the relative position between the dielectric tuning component 200 and the filter 100.

[0058] In some embodiments, the control module 300 includes a processing unit 310, a driving unit 320, and a motor unit 330 that are connected in sequence. The processing unit 310 obtains a control signal from the CPU, outputs a driving signal to the driving unit 320 according to the control signal, the driving unit 320 drives the motor unit 330 according to the driving signal, and the motor unit 330 drives the dielectric tuning component 200 to move, so that the relative position between the dielectric tuning component 200 and the filter 100 is changed, thereby adjusting the operating frequency of the duplexer.

[0059] In some embodiments, the processing unit 310 may adopt a processor or a controller (such as a PLC controller, a PID controller, etc.). The driving unit 320 may adopt a motor driving chip.

[0060] In some embodiments, as Figure 4 shown, the motor unit 330 includes:

[0061] A lifting component 331, which is connected to the dielectric tuning component 200;

[0062] A transmission component 332, which is connected to the lifting component 331 and is configured to control the displacement of the lifting component 331 to control the relative position between the dielectric tuning component 200 and the filter 100;

[0063] A motor 333, which is respectively connected to the driving unit 320 and the transmission component 332 and is configured to drive the transmission component 332.

[0064] In some embodiments, the motor unit 330 includes a motor 333, a transmission assembly 332, and a lifting assembly 331 connected in sequence. The driving unit 320 drives the motor 333, the motor 333 drives the transmission assembly 332 to rotate, the transmission assembly 332 drives the lifting assembly 331 to rise or fall, and the lifting assembly 331 is fixedly connected to the dielectric tuning component 200, thereby driving the dielectric tuning component 200 to displace, so that the relative position between the dielectric tuning component 200 and the filter 100 changes, thereby adjusting the operating frequency of the duplexer.

[0065] In some embodiments, the lifting assembly 331 may adopt a lifting plate. The lifting plate has a through hole, and the dielectric tuning component 200 is fixedly connected to the lifting plate through the through hole. The rise or fall of the lifting plate drives the dielectric tuning component 200 to displace, so that the relative position between the dielectric tuning component 200 and the filter 100 changes, thereby adjusting the operating frequency of the duplexer.

[0066] In some embodiments, as Figure 5 shown, the transmission assembly 332 includes:

[0067] a gear 3321, the gear 3321 is connected to the motor 333;

[0068] a threaded shaft 3322, the threaded shaft 3322 is connected to the gear 3321, the threaded shaft 3322 is threadedly connected to the lifting assembly 331, and the threaded shaft 3322 is used to rotate following the gear 3321 to control the displacement of the lifting assembly 331.

[0069] In some embodiments, the transmission assembly 332 includes a connected gear 3321 and a threaded shaft 3322. The motor 333 drives the gear 3321 to rotate, the gear 3321 drives the threaded shaft 3322 to rotate, the threaded shaft 3322 drives the lifting assembly 331 to rise or fall, and the lifting assembly 331 is fixedly connected to the dielectric tuning component 200, thereby driving the dielectric tuning component 200 to displace, so that the relative position between the dielectric tuning component 200 and the filter 100 changes, thereby adjusting the operating frequency of the duplexer.

[0070] It should be noted that if the transmission assembly 332 uses a pulley drive, due to the risk of vulcanization and aging of the belt, and the insufficient stretching tension of the belt at low temperatures, there will be a problem that it cannot be transmitted at -40 degrees Celsius. In this embodiment, a gear drive is adopted, which can well solve the above problems. In addition, in this embodiment, a threaded shaft is used to connect the gear and the lifting assembly. Since the threaded shaft can accurately control the transmission stroke, the displacement accuracy of the lifting assembly and the calibration accuracy of the zero position can be effectively improved.

[0071] In some embodiments, as Figure 6 shown, the motor unit 330 further includes:

[0072] The position-limiting component 334 is used to limit the displacement of the dielectric tuning component 200.

[0073] The Hall sensor 335 is connected to the control module 300 and is used to detect the displacement data of the dielectric tuning component 200 and send it to the control module 300.

[0074] The control module 300 is further used to determine the zero position of the dielectric tuning component 200 according to the displacement data.

[0075] In some embodiments, the motor unit 330 further includes a position-limiting component 334 and a Hall sensor 335. The position-limiting component 334 is used to limit the displacement of the dielectric tuning component 200. It should be noted that since the lifting component 331 is fixedly connected to the dielectric tuning component 200, the displacement data of the dielectric tuning component 200 can also be called the displacement data of the lifting component 331. The Hall sensor 335 detects the displacement data of the lifting component 331 and sends it to the processing unit 310 of the control module 300. The processing unit 310 determines the zero position of the dielectric tuning component 200 according to the displacement data of the lifting component 331. It should be noted that since the lifting component 331 is fixedly connected to the dielectric tuning component 200, the zero position of the dielectric tuning component 200 can also be called the zero position of the lifting component 331.

[0076] In some embodiments, the specific manner in which the Hall sensor 335 detects the displacement data of the lifting component 331 can be: install a plurality of magnets on the gear 3321. When the gear 3321 rotates, the Hall sensor 335 will detect the rotation of the gear 3321 in real time, and the relationship between the rotation of the gear 3321 and the displacement data generated by the lifting component 331 is known. Therefore, the Hall sensor 335 can detect the displacement data of the lifting component 331 by detecting the rotation of the gear 3321.

[0077] In some embodiments, the Hall sensor 335 can also be replaced by other magnetic sensors.

[0078] In some embodiments, the zero position of the lifting assembly 331 includes a mechanical zero point and an electrical zero point. The mechanical zero point is the position where the lifting assembly 331 matches the limiting assembly 334. The electrical zero point differs from the mechanical zero point by a preset number of driving step values. That is, after the lifting assembly 331 reaches the mechanical zero point, a driving signal with a preset number of driving step values is output to control the lifting assembly 331 to move a certain distance, and then the electrical zero point can be reached. Specifically, after the system is powered on, sufficient driving signals are output to control the lifting assembly 331 to descend continuously until it reaches the position where it matches the limiting assembly 334. At this time, the motor 333 can no longer rotate, and the Hall sensor 335 also no longer feeds back the displacement data of the lifting assembly 331 to the processing unit 310, that is, it is considered that the lifting assembly 331 reaches the mechanical zero point. Then, control the lifting assembly 331 to move upward a certain distance, and the electrical zero point can be reached. Subsequently, each time the operating frequency of the duplexer is adjusted, it is based on the electrical zero point. That is, each time the operating frequency of the duplexer is adjusted, first control the lifting assembly 331 to return to the electrical zero point. Since the lifting assembly 331 is fixedly connected to the dielectric tuning component 200, the lifting assembly 331 returning to the electrical zero point is equivalent to the dielectric tuning component 200 returning to the zero point, and then control the relative position between the dielectric tuning component 200 and the filter 100 to change, thereby adjusting the operating frequency of the duplexer.

[0079] It should be noted that each time the operating frequency of the duplexer is adjusted, it is based on the lifting assembly 331 returning to the electrical zero point, rather than the lifting assembly 331 returning to the mechanical zero point, which can avoid the wear and collision of the components caused by the lifting assembly 331 reaching the position where it matches the limiting assembly 334 every time the frequency is adjusted, and extend the service time of the components.

[0080] In this embodiment, a Hall sensor + mechanical zero position and electrical zero position are used for detection, rather than optoelectronic devices (such as infrared sensors or optical sensors) for detection. This is because using optoelectronic devices may cause the detected zero position to be inaccurate due to reasons such as light occlusion, and further cause the operating frequency of the adjusted duplexer to be inaccurate. Therefore, using a Hall sensor + mechanical zero position and electrical zero position for detecting the zero position in this embodiment can not only improve the detection accuracy, but also solve the cost problem introduced by optoelectronic devices.

[0081] In some embodiments, as Figure 7 shown, the control module 300 further includes:

[0082] A storage unit 340, the storage unit 340 is connected to the processing unit 310, and the storage unit 340 is used to store the mapping relationship between the control signal and the driving step value;

[0083] The processing unit 310 is used to obtain the corresponding driving step value according to the control signal and output a driving signal according to the driving step value.

[0084] In some embodiments, the control module 300 further includes a storage unit 340, which is configured to store the mapping relationship between control signals and driving step values. The processing unit 310 receives the control signals from the CPU of the ODU, retrieves the mapping relationship between control signals and driving step values from the storage unit, obtains the corresponding driving step value according to the control signal, and outputs a driving signal according to the driving step value.

[0085] Combined with the above, each time the operating frequency of the duplexer is adjusted, the CPU of the ODU sends a control signal corresponding to the operating frequency of the duplexer to the processing unit 310. The processing unit 310 first controls the lifting assembly 331 to return to the electrical zero point, then searches for the corresponding driving step value according to the control signal, outputs the corresponding driving signal according to the driving step value, and drives the lifting assembly 331 (or the motor 333) to move the corresponding step value, so as to control the relative position between the dielectric tuning component 200 and the filter 100 to change, thereby adjusting the operating frequency of the duplexer to the required frequency.

[0086] In some embodiments, the filter 100 includes:

[0087] A housing, in which a metal diaphragm is provided, and a cavity is formed in the middle of the housing;

[0088] The dielectric tuning component 200 is placed in the cavity.

[0089] In some embodiments, the filter 100 is an E-plane filter. The E-plane filter can be regarded as an alternating cascade of metal diaphragms and empty waveguides. The metal diaphragm can be equivalent to a T-type network, and the empty waveguide is equivalent to a parallel two-wire line. Its equivalent circuit is as Figure 8 shown, X S1 , X S2 , X S3 and X S4 are equivalent series reactances, and X P1 , X P2 are equivalent shunt reactances. Changing the position of the dielectric tuning component 200 in the cavity, that is, changing the position of the dielectric tuning component 200 relative to the metal diaphragm in the E-plane filter, can change the equivalent series reactances X S1 , X S2 , X S3 and X S4 and the equivalent shunt reactances X P1 , X P2 values, thereby changing the attribute parameters of the E-plane filter, and further adjusting the operating frequency of the duplexer.

[0090] It should be noted that, in some embodiments, such as Figure 9As shown, the drive unit 320, motor unit 330, transmitting waveguide port 130, receiving waveguide port 160, and antenna waveguide port 190 are integrally designed and have a housing 400. A metal diaphragm is embedded in the housing 400 to form an E-plane filter.

[0091] The working principle of the duplexer of the present invention will be described below with a specific embodiment. As Figure 10 shown, the gearbox 410, threaded shaft 3322, lifting plate 420, dielectric tuning component 200, Hall sensor 335, motor 333, and gear 3321 are all integrated in the gearbox 410. As Figure 11 shown, a limit post 421 is provided on the lifting plate 420, and a limit pin 422 is provided on the threaded shaft 3322. It should be noted that the reverse drive signal is used to drive the lifting assembly to displace in the reverse direction, and the reverse displacement means that the lifting assembly displaces in the direction close to the limit assembly. The forward drive signal is used to drive the lifting assembly to displace in the forward direction, and the forward displacement means that the lifting assembly displaces in the direction away from the limit assembly.

[0092] 1) When the duplexer is powered on, the control module outputs a sufficient reverse drive signal, the motor 333 rotates forward, drives the threaded shaft 3322 to rotate clockwise, and controls the lifting plate 420 to descend (i.e., reverse displacement) until the limit post 421 on the lifting plate 420 contacts the limit pin 422 ( Figure 11 which is the structural schematic diagram when the limit post 421 contacts the limit pin 422), and this point is the mechanical zero point.

[0093] 2) After reaching the mechanical zero point, the motor 333 can no longer rotate, and the Hall sensor 335 no longer feeds back signals. It can be set that if no feedback signal from the Hall sensor 335 is received within N consecutive reverse drive signals, it is determined that the mechanical zero point has been reached.

[0094] 3) The control module continues to output a sufficient forward drive signal, the motor 333 rotates in reverse, drives the threaded shaft 3322 to rotate counterclockwise, and a fixed number of forward drive signals can be set to output, controlling the lifting plate 420 to rise (i.e., forward displacement) by a certain safe distance, and this point is the electrical zero point;

[0095] 4) After the electrical zero point position is confirmed, each time the working frequency of the duplexer is adjusted, the relative position of the dielectric tuning component 200 and the E-plane filter is accurately adjusted based on this electrical zero point, so as to achieve the purpose of adjusting the working frequency of the duplexer.

[0096] In the second aspect, as Figure 12 shown, an embodiment of the present invention provides a network device, including:

[0097] The duplexer 500 as described in the first aspect;

[0098] The main control module 600 is connected to the duplexer 500 and is used to send a control signal to the duplexer 500 to adjust the operating frequency of the duplexer 500.

[0099] In some embodiments, the main control module 600 is the CPU of the ODU described in the first aspect. The duplexer 500 is communicatively connected to the CPU, receives the control signal sent by the CPU, and adjusts the operating frequency of the duplexer 500 according to the control signal. For the specific adjustment process, please refer to the description of the embodiments in the first aspect and will not be elaborated here.

[0100] In a third aspect, an embodiment of the present invention provides a duplexer control method applied to the duplexer described in the first aspect. In some embodiments, as Figure 13 shown, the method includes:

[0101] Step S100: Obtain a control signal;

[0102] Step S200: Output a driving signal according to the control signal to control the relative position of the dielectric tuning component and the filter.

[0103] In some embodiments, the relative position of the dielectric tuning component and the filter (internal metal diaphragm) in the duplexer is one of the important factors determining the electrical performance (such as the operating frequency) of the duplexer. The duplexer obtains a control signal, outputs a driving signal according to the control signal to control the relative position of the dielectric tuning component and the filter, so as to achieve the purpose of adjusting the operating frequency of the duplexer, improve the flexibility and application range of the duplexer, and further reduce the inventory pressure of the manufacturer.

[0104] In some embodiments, as Figure 14 shown, step S200 includes:

[0105] Step S210: Obtain a corresponding driving step value according to the control signal;

[0106] Step S220: Output a driving signal according to the driving step value to control the relative position of the dielectric tuning component and the filter.

[0107] In some embodiments, the duplexer receives a control signal from the CPU of the ODU, calls the mapping relationship between the control signal and the driving step value from the storage unit, obtains a corresponding driving step value according to the control signal, and outputs a driving signal according to the driving step value.

[0108] In some embodiments, as Figure 15 shown, before step S100, it further includes:

[0109] Step S110: Output a first reverse drive signal to control the lifting assembly to displace reversely to a position matching the limit assembly, and continuously obtain the displacement data of the lifting assembly;

[0110] Step S120: If no corresponding displacement data is obtained for the reverse drive signals of consecutive N drive step values, it is determined that the lifting assembly has reached the mechanical zero point, where N is a first preset value.

[0111] In some embodiments, before adjusting the operating frequency of the duplexer, it is necessary to detect and calibrate the zero position of the duplexer. Specifically, the duplexer first outputs a first reverse drive signal to control the lifting assembly to displace reversely to a position matching the limit assembly, and continuously obtains the displacement data of the lifting assembly, aiming to detect whether the lifting assembly has reached the mechanical zero point. If no corresponding displacement data is obtained for the second reverse drive signals of consecutive N drive step values, it indicates that the lifting assembly has reached the position matching the limit assembly. At this time, the motor cannot rotate anymore and thus cannot drive the lifting assembly to continue displacing. Therefore, if no corresponding displacement data is obtained within the reverse drive signals of consecutive N drive step values, it is determined that the lifting assembly has reached the mechanical zero point. Here, N is a first preset value. During the practical process, it may be due to reasons such as electrical transmission that displacement data is missed. If it is immediately determined that the lifting assembly has reached the mechanical zero point when no displacement data is detected, misjudgment may occur. In this embodiment, the judgment mechanism that the lifting assembly is determined to have reached the mechanical zero point only when no corresponding displacement data is obtained for the second reverse drive signals of consecutive N drive step values reduces the probability of misjudgment and effectively improves the detection accuracy of the mechanical zero point.

[0112] Preferably, through experiments, it is better to set N to 10, which can not only improve the detection accuracy of the mechanical zero point but also avoid too long detection time.

[0113] In some embodiments, as Figure 16 shown, after step S120, it further includes:

[0114] Step S130: Output a first forward drive signal of M drive step values to control the lifting assembly to displace forward so that the lifting assembly reaches the electrical zero point, where M is a second preset value.

[0115] In some embodiments, after determining that the lifting assembly has reached the mechanical zero point, the duplexer continues to output a first forward drive signal of M drive step values to control the lifting assembly to displace forward so that the lifting assembly reaches the electrical zero point. Here, M is a second preset value and has been preset in the system. Subsequently, each time the operating frequency of the duplexer is adjusted, it is based on the lifting assembly returning to the electrical zero point.

[0116] It should be noted that each time the operating frequency of the duplexer is adjusted, it is based on the lifting component returning to the electrical zero point, rather than the mechanical zero point, which can avoid the wear and collision of the components caused by the need for the lifting component to reach the position matching the limit component every time, and extend the service life of the components.

[0117] In this embodiment, a Hall sensor + mechanical zero position and electrical zero position are used for detection, rather than optoelectronic devices (such as infrared sensors or optical sensors) for detection. This is because using optoelectronic devices may lead to inaccurate zero point positions due to reasons such as light occlusion, and thus the operating frequency of the adjusted duplexer is not accurate enough. Therefore, using a Hall sensor + mechanical zero position and electrical zero position for zero point position detection in this embodiment can not only improve the detection accuracy but also solve the cost problem introduced by optoelectronic devices.

[0118] In some embodiments, as Figure 17 shown, after step S120, it further includes:

[0119] Step S140: Output a second positive drive signal to control the lifting component to displace positively from the mechanical zero point, continuously record the drive step value, and continuously obtain the displacement data of the lifting component;

[0120] Step S150: If no corresponding displacement data is obtained for the third positive drive signal of K consecutive drive step values, determine whether the recorded drive step value meets the third preset value;

[0121] Step S160: Verify the mechanical zero point according to the judgment result.

[0122] In some embodiments, after controlling the lifting component to reach the electrical zero point, it is also necessary to verify whether the mechanical zero point (or electrical zero point) is correct. Specifically, after controlling the lifting component to reach the electrical zero point, the duplexer continues to output a second positive drive signal to control the lifting component to displace positively from the mechanical zero point, continuously record the drive step value, and continuously obtain the displacement data of the lifting component. If no corresponding displacement data is obtained for the third positive drive signal of K consecutive drive step values, it means that the lifting component has displaced to a place where it cannot displace (such as Figure 10 the gearbox), and it cannot displace any further. At this time, determine whether the recorded drive step value meets the third preset value. If it meets the third preset value, the mechanical zero point position is accurate. It can be understood that for operators or manufacturers, the distance from the mechanical zero point to the place where the lifting component cannot displace is fixed, so the number of drive step values required to drive the lifting component from the mechanical zero point to the place where it cannot displace is also fixed.

[0123] For example, the drive step value required for the drive lifting component to move from the mechanical zero point to the point where it cannot move is 4,200, and the drive step value between the mechanical zero point and the electrical zero point is 20. First, output a first reverse drive signal to control the reverse displacement of the lifting component to a position matching the limit component. At this time, the motor cannot rotate, and the Hall sensor no longer feeds back the displacement data of the lifting component, preliminarily determining that the lifting component has reached the mechanical zero point. Then continue to output a second reverse drive signal with 10 (i.e., N = 10) drive step values. If no displacement data of the lifting component is continuously obtained within these 10 drive step values of the second reverse drive signal, it is determined that the lifting component has reached the mechanical zero point. Then continue to output a first forward drive signal with 20 (i.e., M = 20) drive step values to drive the lifting component to move forward to the electrical zero point. At this time, the recorded drive step value is 20. Then continue to output the second forward drive signal to drive the lifting component to continue moving forward. When the lifting component continues to move forward to the point where it cannot move and can no longer continue to move. Continue to output a third forward drive signal with 10 (i.e., K = 10) drive step values. If no displacement data of the lifting component is continuously obtained within these 10 drive step values of the third forward drive signal, it is determined whether the recorded drive step value meets the third preset value. If the recorded drive step value is 4,210 at this time, it exactly meets the third preset value (since the drive step value required for the drive lifting component to move from the mechanical zero point to the point where it cannot move is 4,200, and 10 more drive step values are output later, so the third preset value is theoretically 4,210), thereby verifying that the position of the electrical zero point of the lifting component is correct. If the position of the electrical zero point of the lifting component is incorrect, the above steps are re-executed to re-verify whether the position of the electrical zero point of the lifting component is correct.

[0124] It should be noted that each time the operating frequency of the duplexer is adjusted, it is based on the lifting component returning to the electrical zero point, rather than adjusting based on the position where the lifting component is located after the previous adjustment of the operating frequency. This is because if there is already an error in the position where the lifting component is located after the previous adjustment of the operating frequency, then subsequent frequency adjustments will cause the error to continue to accumulate, and the adjusted frequency will become more and more inaccurate. Therefore, in this embodiment, each time the operating frequency of the duplexer is adjusted, it is based on the lifting component returning to the electrical zero point. Then the calibration and verification of the electrical zero point are particularly important, which can effectively avoid the influence of the previous error on the current frequency adjustment, thereby improving the accuracy of the frequency adjustment.

[0125] In some embodiments, as Figure 18 shown, step S200 includes:

[0126] Step S210: Obtain a third reverse drive signal and a fourth forward drive signal according to the control signal;

[0127] Step S220: Output a third reverse drive signal to control the lifting component to reach the electrical zero point;

[0128] Step S230: Output a fourth forward drive signal to control the relative position of the dielectric tuning component and the filter.

[0129] In some embodiments, assuming that the lifting component is currently exactly at the electrical zero point, there is no need to return to the electrical zero point. The duplexer directly obtains the corresponding drive step value according to the control signal, and outputs a fourth forward drive signal according to the drive step value to control the relative position of the dielectric tuning component and the filter.

[0130] In some embodiments, assuming that the lifting component is not currently at the electrical zero point, it needs to return to the electrical zero point first and then start adjusting the frequency. If the working frequency of the duplexer was adjusted to the preset frequency F1 last time, and the drive step value corresponding to the drive signal output by the duplexer was X, then when adjusting the working frequency of the duplexer this time, it is necessary to first output a reverse drive signal (i.e., the third reverse drive signal) with X drive step values to control the lifting component to return to the electrical zero point. In some embodiments, the number X of the drive step values output last time needs to be stored in the storage unit. The duplexer needs to obtain X from the storage unit, and then output a reverse drive signal with X drive step values according to X. After controlling the lifting component to return to the electrical zero point, receive the control signal sent by the CPU of the ODU. This control signal indicates which frequency the working channel of the duplexer needs to be adjusted to this time. Call the mapping relationship between the control signal and the drive step value from the storage unit, obtain the corresponding drive step value according to the control signal, and output a fourth forward drive signal according to the drive step value to control the relative position of the dielectric tuning component and the filter, thereby adjusting the working frequency of the duplexer.
