The monitoring module sends a test command to a signal generator, and the test command is used to instruct the signal generator to generate a first pilot signal with a first power sent to the filter. The monitoring module receives the second power of the second pilot signal, and the second power is determined by the signal receiver according to the received second pilot signal.

[0026] In order to make the purpose, technical solution and beneficial effects of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Figure 1 An exemplary system architecture diagram applicable to the embodiment of the present application is shown as follows: Figure 1 As shown, the system includes a filter 101, a signal generator 102, a signal receiver 103, a monitoring module 104 and an adjustable module 105.

[0028] In the embodiment of the present application, the monitoring module 104 may send a test command to the signal generator 102, the test command being used to instruct the signal generator 102 to generate a first pilot signal, and send the first pilot signal having a first power to the filter 101. The first pilot signal is a pilot signal for the detection frequency of the filter 101.

[0029] Since the adjusted filter 101 and the adjustable module 105 filter the signal as a whole, the adjustment of the adjustable module 105 by the monitoring module 104 in the system can directly affect the indicators of the filter 101. If the indicators of the filter 101 meet the requirements after adjustment, the signal generator 102 and the signal receiver 103 used in the adjustment process can be removed, and the filter 101 and the adjustable module 105 are placed in a new link as a whole to filter the signal.

[0030] In an optional implementation, Figure 1 The system shown also includes a first radio frequency switch, a second radio frequency switch, a signal input port, and a signal output port. Figure 2 An exemplary system architecture diagram applicable to the embodiment of the present application is shown as follows: Figure 2 As shown, except Figure 1 In addition to the filter 101 , the signal generator 102 , the signal receiver 103 , the monitoring module 104 and the adjustable module 105 described above, the system further includes a first RF switch 106 , a second RF switch 107 , a signal input port 108 and a signal output port 109 .

[0031] The first RF switch 106 is disposed between the signal generator 102 and the filter 101.

[0032] Similarly, the second RF switch 107 is disposed between the signal receiver 103 and the filter 101.

[0033] Figure 3 The flowchart of a filter index adjustment method applicable to an embodiment of the present application is exemplarily shown, which is applicable to a system including a filter, a signal generator, a signal receiver, a monitoring module and an adjustable module, such as Figure 3 As shown, including:

[0034] Step 301: The monitoring module sends a test command to the signal generator, where the test command is used to instruct the signal generator to generate a first pilot signal with a first power to be sent to the filter, where the first pilot signal is a pilot signal for a detection frequency point of the filter;

[0035] Step 302: The monitoring module receives a second power of a second pilot signal, where the second power is determined by the signal receiver according to the received second pilot signal, where the second pilot signal is a pilot signal after the first pilot signal is processed by a filter;

[0036] Step 303, the monitoring module determines the actual index of the detection frequency point according to the second power and the first power. If the difference between the actual index and the standard index of the detection frequency point exceeds the preset range, an adjustment instruction is sent to the adjustable module; the adjustment instruction is used to instruct the adjustable module to adjust the filter according to the adjustment instruction until the difference between the actual index and the standard index at the detection frequency point meets the preset range.

[0037] In the embodiment of the present application, the monitoring module sends a test command to the signal generator, the test command is used to instruct the signal generator to generate a first pilot signal with a first power sent to the filter, the monitoring module receives the second power of the second pilot signal, the second power is determined by the signal receiver according to the received second pilot signal, the second pilot signal is the pilot signal after the first pilot signal is processed by the filter, the monitoring module determines the actual index of the detection frequency point according to the second power and the first power, if the difference between the actual index and the standard index of the detection frequency point exceeds the preset range, then send an adjustment instruction to the adjustable module, the adjustment instruction is used to instruct the adjustable module to adjust the filter according to the adjustment instruction, until the difference between the actual index and the standard index at the detection frequency point meets the preset range. Since the standard index of the filter can be obtained by debugging the adjustable module through the monitoring module, and the above process is completely determined by the monitoring module according to the difference between the actual index and the standard index of the detection frequency point until the requirements are met, the human resources required in the debugging process can be reduced.

[0038] In the embodiment of the present application, the detection frequency in step 301 includes the detection frequency on the working bandwidth and the detection frequency on the non-working bandwidth. Assuming that the working bandwidth of the filter is 1010MHz-1020MHz, the non-working bandwidth of the working bandwidth of the filter is the bandwidth other than 1010MHz-1020MHz.

[0039] Based on the above assumptions of working bandwidth and non-working bandwidth, in an optional implementation, the monitoring module can select several detection frequencies from the working bandwidth of the filter 1010MHz-1020MHz, such as 1010MHz, 1011MHz, 1012MHz, 1013MHz, 1014MHz, 1015MHz, 1016MHz, 1017MHz, 1018MHz, 1019MHz, 1020MHz, these 11 detection frequencies. The monitoring module can also select several detection frequencies from the non-working bandwidth of the filter, such as the detection frequencies 1005MHz, 1006MHz, 1007MHz, 1008MHz, 1009MHz, 1021MHz, 1022MHz, 1023MHz, 1024MHz, 1025MHz, these 10 detection frequencies.

[0040] Optionally, the test command may include each detection frequency point of the determined filter in the working bandwidth and the non-working bandwidth, and the test command is used to instruct the signal generator to generate a first pilot signal with a first power to be sent to the filter, and the first power of the first pilot signal at each detection frequency point may be 0 dBm. Based on the above detection frequency point example, the first power of the first pilot signal at the 11 detection frequency points on the working bandwidth is 0 dBm; the first power of the first pilot signal at the 10 detection frequency points on the non-working bandwidth is 0 dBm.

[0041] In a first optional implementation, the first power of the first pilot signal at each detection frequency is determined by the monitoring module. The first power may be included in a test command sent by the monitoring module to the signal generator. After receiving the test command, the signal generator may determine each detection frequency, determine the first power of the first pilot signal at each detection frequency, and send the first pilot signal with the first power to the filter.

[0042] In a second optional implementation, the first pilot signal at each detection frequency is determined by a signal generator. The signal generator receives the test command, can determine each detection frequency, and determine the first power of the first pilot signal at each detection frequency. The signal generator sends the first power of the first pilot signal at each detection frequency to the monitoring module, and at the same time, the first pilot signal with the first power is sent to the filter.

[0043] In step 302, after the first pilot signal with the first power at each detection frequency point in the working bandwidth and non-working bandwidth of the filter is processed by the filter, the second pilot signal with the second power at each detection frequency point can be output. After the signal receiver receives the second pilot signal, the second power of the second pilot signal at each detection frequency point can be determined, and the second power at each detection frequency point is sent to the monitoring module.

[0044] Since the power of the first pilot signal after the filter changes, the powers of the first pilot signal and the second pilot signal based on the same detection frequency are different. Therefore, based on the above detection frequency, the second power of the second pilot signal at the detection frequency of 1010 MHz is -3 dBm, the second power of the second pilot signal at the detection frequency of 1011 MHz is -2.8 dBm, the second power of the second pilot signal at the detection frequency of 1012 MHz is -2.7 dBm, the second power of the second pilot signal at the detection frequency of 1013 MHz is -2.6 dBm, and the second power of the second pilot signal at the detection frequency of 1014 MHz is -2.8 dBm. The second power of the second pilot signal at the detection frequency point 1015MHz is -2.5dBm, the second power of the second pilot signal at the detection frequency point 1016MHz is -2.6dBm, the second power of the second pilot signal at the detection frequency point 1017MHz is -2.7dBm, the second power of the second pilot signal at the detection frequency point 1018MHz is -2.8dBm, the second power of the second pilot signal at the detection frequency point 1019MHz is -2.9dBm, and the second power of the second pilot signal at the detection frequency point 1020MHz is -3dBm. The second power of the second pilot signal at the detection frequency point 1005MHz is -20dBm, the second power of the second pilot signal at 1006MHz is -17dBm, the second power of the second pilot signal at 1007MHz is -15dBm, the second power of the second pilot signal at 1008MHz is -12dBm, the second power of the second pilot signal at 1009MHz is -10dBm, the second power of the second pilot signal at 1021MHz is -10dBm, the second power of the second pilot signal at 1022MHz is -12dBm, the second power of the second pilot signal at 1023MHz is -15dBm, the second power of the second pilot signal at 1024MHz is -18dBm, and the second power of the second pilot signal at 1025MHz is -20dBm.

[0045] In step 303, based on the first power and the second power at each detection frequency, the monitoring module can determine the actual index of each detection frequency. Optionally, the monitoring module can determine the actual index of the detection frequency according to the difference between the second power and the first power.

[0046] For example, the actual index of each detection frequency point on the working bandwidth is: the actual index of the detection frequency point 1010MHz is -3dB, the actual index of the detection frequency point 1011MHz is -2.8dB, the actual index of the detection frequency point 1012MHz is -2.7dB, the actual index of the detection frequency point 1013MHz is -2.6dB, the actual index of the detection frequency point 1014MHz is -2.5dB, the actual index of the detection frequency point 1015MHz is -2.5dB, the actual index of the detection frequency point 1016MHz is -2.6dB, the actual index of the detection frequency point 1017MHz is -2.7dB, the actual index of the detection frequency point 1018MHz is -2.8dB, the actual index of the detection frequency point 1019MHz is -2.9dB, and the actual index of the detection frequency point 1020MHz is -3dB. That is to say, the power of the pilot signal passing through the filter at each detection frequency point on the above working bandwidth is attenuated within 3dB.

[0047] For example, the actual index of each detection frequency point on the non-working bandwidth is -20dB for detection frequency point 1005MHz, -17dB for 1006MHz, -15dB for 1007MHz, -12dB for 1008MHz, -10dB for 1009MHz, -10dB for 1021MHz, -10dB for 1022MHz, -12dB for 1023MHz, -15dB for 1024MHz, -18dB for 1025MHz. That is to say, the power of the pilot signal passing through the filter at each detection frequency point on the non-working bandwidth is attenuated and the attenuation value is above 10dB (including 10dB).

[0048] In an optional implementation, before the monitoring module determines the detection frequency points on the working bandwidth and the detection frequency points on the non-working bandwidth of the filter, the standard index of each detection frequency point can be determined, such as the standard index of each detection frequency point on the working bandwidth is -3dB, and the standard index of each detection frequency point on the non-working bandwidth is -15dB. In step 303, if the difference between the actual index and the standard index of each detection frequency point on the working bandwidth meets the preset range, and the difference between the actual index and the standard index of each detection frequency point on the non-working bandwidth exceeds the preset range, the monitoring module can send an adjustment instruction to the adjustable module, and the adjustment instruction is used to instruct the adjustable module to adjust the filter according to the adjustment instruction.

[0049] Optionally, the adjustable module may be a variable diode, a resistor, a capacitor, etc. Specifically, the monitoring module may adjust the voltage of the variable diode and adjust the filter by changing the voltage of the variable diode.

[0050] Since the monitoring module in the system can directly affect the index of the filter by adjusting the adjustable module, before step 301, that is, before the monitoring module sends a test command to the signal generator, in an optional implementation, the monitoring module can give the adjustable module an initial voltage, in an optional implementation. The monitoring module can determine the initial voltage of the adjustable module according to the standard index of the filter, and send an initialization instruction to the adjustable module according to the initial voltage, wherein the initialization instruction is used to adjust the voltage of the adjustable module to the initial voltage. Since the initial voltage is calculated according to the standard index of the filter, that is, the standard index of each detection frequency point on the working bandwidth in the above example is -3dB, for example, the standard index of each detection frequency point on the non-working bandwidth is -15dB, so the obtained initial voltage can be basically close to the adjusted target voltage, so that the number of times the adjustable module voltage is adjusted can be saved.

[0051] In an optional embodiment, the adjustable module includes an adjustable submodule, which can be a varactor diode. If the difference between the actual index and the standard index of the detection frequency exceeds the preset range, for example, the difference between the actual index and the standard index of each detection frequency on the working bandwidth meets the preset range, and the difference between the actual index and the standard index of each detection frequency on the non-working bandwidth exceeds the preset range. The monitoring module generates a first adjustment instruction and sends it to the adjustable submodule. The first adjustment instruction is used to instruct the adjustable submodule to adjust the filter according to the first adjustment instruction, for example, the first adjustment instruction is to increase the voltage of the adjustable submodule by 50 mA.

[0052] The monitoring module continues to instruct the signal generator to generate a first pilot signal with a first power of 0dBm at each detection frequency point. After being processed by the filter, a third pilot signal with a third power at each detection frequency point is obtained. The monitoring module determines the actual index of each detection frequency point based on the difference between the third power and the first power. If the difference between the actual index and the standard index of each detection frequency point on the working bandwidth meets the preset range, and the difference between the actual index and the standard index of each detection frequency point on the non-working bandwidth also meets the preset range, the voltage of the adjustable module is saved and the process ends. This means that the filter and the adjusted adjustable module can meet the required requirements and can be put into use.

[0053] If the difference between the actual index and the standard index of each detection frequency point on the working bandwidth meets the preset range, and the difference between the actual index and the standard index of each detection frequency point on the non-working bandwidth still exceeds the preset range, but the value exceeding the preset range is relatively small, the monitoring module can generate a second adjustment instruction and send it to the adjustable module, and the second adjustment instruction is to increase the voltage of the adjustable submodule by 50 mA. Until the difference between the actual index and the standard index at the detection frequency meets the preset range. If the difference between the actual index and the standard index of each detection frequency point on the working bandwidth meets the preset range, and the difference between the actual index and the standard index of each detection frequency point on the non-working bandwidth still exceeds the preset range, but the value exceeding the preset range is larger than the previous one, the monitoring module can generate a second adjustment instruction and send it to the adjustable module, and the second adjustment instruction is to reduce the voltage of the adjustable submodule by 100 mA. Until the difference between the actual index and the standard index at the detection frequency meets the preset range.

[0054] In another optional implementation, the adjustable module includes a plurality of adjustable submodules, assuming that there are a first variable diode and a second variable diode. If the difference between the actual index and the standard index of the detection frequency exceeds the preset range, for example, the difference between the actual index and the standard index of each detection frequency on the working bandwidth meets the preset range, and the difference between the actual index and the standard index of each detection frequency on the non-working bandwidth exceeds the preset range. The monitoring module determines one or more adjustable submodules to be adjusted from the plurality of adjustable submodules, such as determining the first variable diode, generates an adjustment instruction for the first variable diode, and sends the adjustment instruction to the first variable diode.

[0057] Step 402: The monitoring module determines the initial voltage of the adjustable module according to the standard index at each detection frequency point of the filter, and sends an initialization instruction to the first variable diode and the second variable diode according to the initial voltage, wherein the initialization instruction is used to adjust the voltage of the first variable diode and the voltage of the second variable diode to the initial voltage;

[0058] Step 403: the monitoring module sends a test command to the signal generator, where the test command is used to instruct the signal generator to generate a first pilot signal having a first power at each detection frequency point sent to the filter;

[0059] Step 404: The monitoring module receives a second power of a second pilot signal, where the second power is determined by the signal receiver according to the received second pilot signal, where the second pilot signal is a pilot signal after the first pilot signal is processed by a filter;

[0060] Step 405, the monitoring module determines the actual index of each detection frequency point according to the second power and the first power;

[0061] Step 406: The monitoring module determines the difference between the actual index and the standard index on the working bandwidth as the first index difference; and determines the difference between the actual index and the standard index on the non-working bandwidth as the second index difference;

[0062] Step 407, the monitoring module determines whether the first indicator difference and the second indicator difference meet the preset range. If the first indicator difference meets the preset range and the second indicator difference exceeds the preset range, go to step 408; otherwise, go to step 411;

[0063] Step 408, the monitoring module determines the second variable diode, generates an adjustment instruction for the second variable diode, and sends the adjustment instruction to the second variable diode;

[0064] Step 409: the monitoring module receives a third power of a third pilot signal, where the third power is determined by the signal receiver according to the received third pilot signal, and the third pilot signal is a pilot signal after the first pilot signal is processed by the adjusted filter;

[0065] Step 410, the monitoring module determines whether the adjusted first indicator difference and the second indicator difference meet the preset range. If the first indicator difference meets the preset range and the second indicator difference meets the preset range, the adjustment process ends; otherwise, go to step 411;

[0066] Step 411 , the monitoring module determines the first variable diode, generates an adjustment instruction for the first variable diode, and sends the adjustment instruction to the first variable diode, and then goes to step 409 .

[0067] In the above implementation, if either the first indicator difference or the second indicator difference exceeds the preset range, the voltage of only one varactor diode is adjusted at a time, and the voltages of two varactor diodes can be optionally adjusted at a time. The monitoring module can determine the adjustment rule after multiple adjustments, and determine whether the voltage is adjusted upward or downward according to the adjustment rule.

[0068] based on Figure 2In the system diagram shown, before step 301, that is, before the monitoring module sends a test command to the signal generator, in an optional implementation, the monitoring module can send a first instruction to the first RF switch, and the first instruction is used to turn on the first interface on the first RF switch. At this time, the first RF switch is connected to the signal generator through the first interface. At the same time, the monitoring module can send a third instruction to the second RF switch, and the third instruction is used to turn on the third interface on the second RF switch. At this time, the second RF switch is connected to the signal receiver through the third interface.

[0069] After the difference between the actual index and the standard index at the detection frequency point meets the preset range, in an optional implementation, the monitoring module sends a second indication to the first RF switch, and the second indication is used to turn on the second interface on the first RF switch, and the second interface is connected to the signal input port. Similarly, the controlled module sends a fourth indication to the second RF switch, and the fourth indication is used to turn on the fourth interface on the second RF switch, and the fourth interface is connected to the signal output port. In this way, the monitoring module can control the first RF switch to connect to the signal generator and the second RF switch to connect to the signal receiver before adjustment, in preparation for adjusting the standard index of the filter. After the adjustment, the first RF switch can be controlled to connect to the signal input port, and the second RF switch can be controlled to connect to the signal output port. The signal input port and the signal output port can exist in the product circuit. In this way, the filter can be directly controlled by the monitoring module to be present in the adjustment circuit for adjustment or to work in the product circuit, thereby realizing the function of adaptively adjusting the filter index.
