[0069] Figure 1 is a flowchart of Embodiment 1 of the present invention;

[0070] Figure 2 It is a system block diagram of embodiment 2 of the present invention. DETAILED DESCRIPTION

[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] Example 1

[0073] See also Figure 1 As shown, the present invention is a method for adjusting the angle of a microwave antenna, comprising the following steps:

[0074] Step 1: Obtain receiving status data of the microwave antenna and calculate the bit error rate evaluation index;

[0075] The receiving status data refers to the bit error rate of the signal received by the microwave antenna;

[0076] In some embodiments, a detection period is set, the detection period is evenly divided into a number of detection time periods, and a bit error rate of a signal received by a microwave antenna in the detection time period is obtained;

[0077] It should be explained that the bit error rate refers to the ratio of the number of erroneous bits to the total number of bits sent. At the receiving end, the received analog signal is restored to binary data through the corresponding demodulation technology, so that the number of bits can be obtained. The demodulation technology is an existing technology. In addition, the bit error rate is the average of the bit error rates in the detection period;

[0078] The bit error rate in the detection period is calculated to be different from the bit error rate preset value to obtain the bit error rate difference;

[0079] Then the bit error rate difference is calculated by ratio with the bit error rate preset value to obtain the bit error rate degree value;

[0080] It should be explained that the preset value of the bit error rate is the highest value of the ratio of the number of bits to the total number of bits sent without affecting the receiving quality of the microwave antenna, and its value is set by relevant personnel in this field;

[0081] Calculate the average of all bit error rate values ​​within the detection period to obtain a bit error rate estimation value;

[0082] Furthermore, the variance of the bit error rate in all detection periods is calculated to obtain the bit error rate fluctuation value;

[0083] Perform weighted calculation on the bit error rate degree estimation value and the bit error rate fluctuation value to obtain a bit error rate evaluation index;

[0084] It should be explained that the bit error rate evaluation index is a comprehensive evaluation value of the receiving state of the microwave antenna through the fluctuation of the bit error rate and the degree of difference of the bit error rate.

[0085] Step 2: judging whether the receiving state of the microwave antenna is qualified according to the bit error rate evaluation index, and generating a receiving state signal;

[0086] The receiving state signal includes a receiving state qualified signal and a receiving state unqualified signal;

[0087] In some embodiments, obtaining a bit error rate assessment index, and comparing the bit error rate assessment index with a bit error rate assessment index threshold;

[0088] It should be noted that the bit error rate evaluation index threshold is consistent with the bit error rate evaluation index calculation method, and its specific acquisition method is to set the values ​​of the bit error rate degree value and the bit error rate fluctuation value, and its values ​​are set by relevant personnel in this field;

[0089] If the bit error rate evaluation index is less than or equal to the bit error rate evaluation index threshold, it means that the lower the bit error rate evaluation index is, the better the receiving state of the microwave antenna is, and a receiving state qualified signal is generated;

[0090] If the bit error rate evaluation index is greater than the bit error rate evaluation index threshold, it means that the higher the bit error rate evaluation index is, the worse the receiving state of the microwave antenna is, and a reception state unqualified signal is generated.

[0091] Step 3: Based on the unqualified reception state signal, the signal-to-noise data of the microwave antenna is obtained, and the signal-to-noise ratio evaluation index is calculated;

[0092] Among them, signal-to-noise data refers to the signal-to-noise ratio;

[0093] In some embodiments, obtaining a signal-to-noise ratio of a signal received by a microwave antenna during a detection period;

[0094] It should be noted that the signal-to-noise ratio represents the ratio between the signal power or amplitude and the noise power or amplitude, and its acquisition method is the existing technology, and the corresponding signal and noise power or amplitude can be extracted from the data received by the microwave antenna;

[0095] The difference between the signal-to-noise ratio in the detection period and the preset value of the signal-to-noise ratio is calculated to obtain the signal-to-noise ratio difference;

[0096] Then the signal-to-noise ratio difference is calculated with the preset value of the signal-to-noise ratio to obtain the signal-to-noise ratio value;

[0097] It should be explained that the preset value of the signal-to-noise ratio is the lowest value of the ratio between the signal power or amplitude and the noise power or amplitude without affecting the microwave antenna receiving the signal and being able to analyze it, and its value is set by relevant personnel in this field;

[0098] Calculate the mean of all signal-to-noise ratio values ​​within the detection period to obtain an estimated signal-to-noise ratio value;

[0099] Furthermore, the variance of the signal-to-noise ratio in all detection periods is calculated to obtain the signal-to-noise ratio fluctuation value;

[0100] The signal-to-noise ratio evaluation index is obtained by weighting the signal-to-noise ratio estimation value and the signal-to-noise ratio fluctuation value;

[0101] It should be explained that the signal-to-noise ratio evaluation index is a comprehensive evaluation value of the signal-to-noise ratio status of the microwave antenna receiving data through the fluctuation of the signal-to-noise ratio and the degree of difference in the signal-to-noise ratio.

[0102] Step 4: judging the signal-to-noise ratio status of the data received by the microwave antenna according to the signal-to-noise ratio evaluation index, and generating a signal-to-noise ratio status signal;

[0103] The signal-to-noise ratio status signal includes a normal signal-to-noise ratio signal and an abnormal signal-to-noise ratio signal;

[0104] In some embodiments, a signal-to-noise ratio evaluation index is obtained, and the signal-to-noise ratio evaluation index is compared with a signal-to-noise ratio evaluation index threshold;

[0105] It should be noted that the calculation method of the signal-to-noise ratio evaluation index threshold is consistent with the calculation method of the signal-to-noise ratio evaluation index. The specific method for obtaining the threshold is to set the values ​​of the signal-to-noise ratio degree value and the signal-to-noise ratio fluctuation value, and the values ​​are set by relevant personnel in this field.

[0106] If the signal-to-noise ratio evaluation index is greater than or equal to the signal-to-noise ratio evaluation index threshold, it means that the higher the signal-to-noise ratio evaluation index is, the better the signal-to-noise ratio state of the microwave antenna receiving data is, and a normal signal-to-noise ratio signal is generated; when the normal signal-to-noise ratio signal is received, it is necessary to further process the cause of the excessively high bit error rate of the microwave antenna receiving data;

[0107] If the signal-to-noise ratio evaluation index is less than the signal-to-noise ratio evaluation index threshold, it means that the lower the signal-to-noise ratio evaluation index is, the worse the signal-to-noise ratio state of the microwave antenna receiving data is, and a signal-to-noise ratio abnormal signal is generated.

[0108] Step 5: Based on the abnormal signal-to-noise ratio signal, the signal-to-noise-receiving state involvement evaluation index is calculated according to the signal-to-noise data and the receiving state data;

[0109] In some embodiments, the signal-to-noise ratio and the bit error rate of the data received by all microwave antennas in the detection period are obtained;

[0110] A coordinate system is established with the detection period as the X-axis and the signal-to-noise ratio as the Y-axis, and the signal-to-noise ratio of the microwave antenna receiving data in all detection periods is substituted into the coordinate system to generate a signal-to-noise ratio scatter plot;

[0111] The coordinates of adjacent points in the signal-to-noise ratio scatter plot are calculated by difference to obtain the change value of the signal-to-noise ratio during the detection period;

[0112] Then, the ratio of the change value of the signal-to-noise ratio in the detection period to the initial signal-to-noise ratio in the corresponding detection period is calculated to obtain the change rate of the signal-to-noise ratio in the detection period;

[0113] Furthermore, a coordinate system is established with the detection period as the X-axis and the bit error rate as the Y-axis, and the bit error rates of the microwave antenna receiving data in all detection periods are substituted into the coordinate system to generate a bit error rate scatter plot;

[0114] The coordinates of adjacent points in the bit error rate scatter plot are calculated by difference to obtain the change value of the bit error rate during the detection period;

[0115] Then, the change value of the bit error rate in the detection period is calculated by ratio with the initial bit error rate in the corresponding detection period to obtain the change rate of the bit error rate in the detection period;

[0116] The difference between the bit error rate change rate and the signal-to-noise ratio change rate in the detection period is calculated to obtain the bit error-signal-to-noise change rate difference;

[0117] Compare the bit error-signal-noise change rate difference value within the detection period with the bit error-signal-noise change rate error value;

[0118] It should be explained that the error value of the bit error-signal-to-noise change rate error is the maximum error value that can be generated by the difference between the change rates of the signal-to-noise ratio and the change rate of the bit error rate during the detection period; in addition, it is well known to relevant personnel in the field that the signal-to-noise ratio can affect the bit error rate. What needs to be judged here is whether there are other influencing factors between the two during the detection period;

[0119] If the bit error-signal-noise change rate difference is less than or equal to the bit error-signal-noise change rate error value, then the detection period is marked as involving a normal period;

[0120] If the bit error-signal-noise change rate difference is greater than the bit error-signal-noise change rate error value, the detection period is marked as an abnormal period;

[0121] Obtaining the number of normal time periods involved, calculating the ratio of the number of normal time periods involved to the total number of detection time periods, and obtaining a signal-to-noise-reception state involvement evaluation index;

[0122] Step 6: judging the correlation strength between the signal-noise data and the receiving state data according to the signal-noise-receiving state correlation evaluation index, and generating a signal-noise-receiving state correlation strength signal;

[0123] The signal-to-noise-receiving state involving strength signal includes a signal-to-noise-receiving state involving strong signal and a signal-to-noise-receiving state involving weak signal;

[0124] In some embodiments, a signal-to-noise-reception state involvement evaluation index is obtained, and the signal-to-noise-reception state involvement evaluation index is compared with a signal-to-noise-reception state involvement evaluation index threshold;

[0125] It should be noted that the signal-to-noise-reception state involvement evaluation index threshold is consistent with the calculation method of the signal-to-noise-reception state involvement evaluation index, and its specific acquisition method can be set and calculated by setting the value of the number of normal time periods involved, and its value is set by relevant personnel in this field;

[0126] If the signal-noise-reception state involvement evaluation index is less than or equal to the signal-noise-reception state involvement evaluation index threshold, it means that the smaller the signal-noise-reception state involvement evaluation index is, the weaker the strength of the involvement between the signal-noise-reception state in the detection period is, and a signal-noise-reception state involvement weak signal is generated; when a signal-noise-reception state involvement weak signal is received, it is necessary to further process the cause of the signal-noise-reception state involvement weak;

[0127] If the signal-noise-reception state involvement evaluation index is greater than the signal-noise-reception state involvement evaluation index threshold, it means that the larger the signal-noise-reception state involvement evaluation index is, the stronger the intensity of the involvement between the signal-noise-reception state in the detection period is, and a signal-noise-reception state strong involvement signal is generated.

[0128] Step 7: Based on the signal-to-noise-receiving state involving a strong signal, an angle adjustment test is performed on the microwave antenna angle, the signal-to-noise ratio data during the angle adjustment test is obtained, and the microwave antenna angle adjustment value is calculated;

[0129] Among them, the signal-to-noise ratio data refers to the signal-to-noise ratio debugging change value;

[0130] In some embodiments, an angle adjustment test is performed on all angles, and a signal-to-noise ratio change value of the microwave antenna signal during each angle adjustment test within a detection period is obtained and marked as a signal-to-noise ratio debugging change value;

[0131] It should be noted that the signal-to-noise ratio adjustment change value refers to the difference between the signal-to-noise ratio after the angle adjustment test and the signal-to-noise ratio before the test; in addition, the value of the test angle is set by relevant personnel in this field;

[0132] Compare the signal-to-noise ratio debugging change value with 0;

[0133] If the signal-to-noise ratio debugging change value is less than or equal to 0, it means that the angle adjustment test is a negative adjustment, so the angle is marked as a negative adjustment angle, the microwave antenna is reset, and other angles are selected to continue the test;

[0134] If the signal-to-noise ratio debugging change value is greater than 0, it means that the angle adjustment test is a positive adjustment, and the angle is marked as a positive adjustment angle;

[0135] Get the angle change value of the positive adjustment angle through the formula , calculate the adjustment angle value Cp; where Mc represents the required correction value of the bit error rate, Xs represents the noise ratio debugging change value during the forward angle adjustment process, Cs represents the angle change value of the forward angle adjustment, and α represents the correlation coefficient between the signal-to-noise ratio and the bit error rate within the detection period;

[0136] It should be noted that the correlation coefficient α between the signal-to-noise ratio and the bit error rate within the detection period can be calculated by linear regression;

[0137] When the adjustment angle value Cp is obtained, the microwave antenna is adjusted in angle according to the adjustment angle value Cp, with the positive adjustment angle as the direction.
