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.

[0064] The calibration method of the wireless communication module provided in the embodiment of the present application can be applied to the application environment of the wireless communication module calibration. The method can be applied to a terminal, a server, or a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. Among them, the terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, etc. Among them, the terminal converts the calibration process of the wireless communication module into an automatic calibration process through automation software, and in the automatic calibration process, the current signal transmission parameters are automatically obtained, so that the signal calibration information of the manual operation, the fitting process of the attenuation value calibration fitting table, and the calibration verification process of the wireless communication module are replaced by an automation program, which not only improves the calibration timeliness of the wireless communication module, but also avoids error problems in the process of automatic calibration, improves the calibration accuracy, and thus comprehensively improves the efficiency of calibrating the wireless communication module.

[0065] In one embodiment, Figure 1 As shown, a calibration method for a wireless communication module is provided, which is described by taking the method applied to a terminal as an example, and includes the following steps:

[0066] Step S101: acquiring current signal transmission parameters of the wireless communication module, and identifying power information of the wireless communication module based on the current signal transmission parameters.

[0067] In this embodiment, the terminal obtains the calibration strategy of the wireless communication module in response to the user's information upload operation. The terminal can also identify the current signal transmission parameters of the wireless communication module by detecting the signal transmission data of the wireless communication module. Among them, the wireless communication module is a communication module provided in each wireless communication device. The wireless communication device is, for example, a walkie-talkie, a radio station, an unmanned system, a Bluetooth device, a wireless network device, etc. Among them, the current signal transmission parameters are the basic parameters of the wireless communication module when transmitting signals to the outside, for example, the parameters corresponding to the transmission frequency point, the transmission attenuation value, the power and other data. Then, the terminal identifies the power information of the wireless communication module based on the current signal transmission parameters. Among them, the power information is the power value of the center frequency point in the transmission frequency point on the wireless module. The specific identification process will be described in detail later.

[0068] Step S102: Based on the power information and through the calibration strategy of the wireless communication module, the signal calibration information of the wireless communication module is identified, and based on each signal calibration information, an attenuation value calibration fitting table of the wireless communication module is generated.

[0069] In this embodiment, the terminal identifies the signal calibration information of the wireless communication module based on the power information and the calibration strategy of the wireless communication module, and generates an attenuation value calibration fitting table of the wireless communication module based on each signal calibration information. The calibration strategy is a calibration strategy for calibrating the attenuation value of different transmission frequencies of the wireless communication module, and the specific identification process will be described in detail later. Finally, the terminal generates an attenuation value calibration fitting table of the wireless communication module based on the calibration information of each signal. The attenuation value calibration fitting table is the actual calibration value of the fitting attenuation value corresponding to the transmission frequency of different unit steps. The unit step size is, for example, 1MHz. The specific generation process will be described in detail later.

[0070] Step S103, calibrating the wireless communication module through the attenuation value calibration fitting table to obtain a target wireless communication module.

[0071] In this embodiment, the terminal calibrates the wireless communication module through the attenuation value calibration fitting table to obtain the target wireless communication module.

[0072] Based on the above scheme, the calibration process of the wireless communication module is converted into an automatic calibration process through automated software, and in the automatic calibration process, the current signal transmission parameters are automatically acquired, so that the manually operated signal calibration information identification, the fitting process of the attenuation value calibration fitting table, and the calibration verification process of the wireless communication module are replaced by automated procedures. This not only improves the calibration timeliness of the wireless communication module, but also avoids error problems in the automated calibration process, improves the calibration accuracy, and thus comprehensively improves the efficiency of calibrating the wireless communication module.

[0073] Optionally, based on current signal transmission parameters, the power information of the wireless communication module is identified, including: based on the current signal transmission parameters, identifying the transmission frequency point of the wireless communication module and the transmission attenuation value of the wireless communication module; configuring the center frequency point of the target spectrum analyzer as the transmission frequency point, and based on the transmission attenuation value, identifying the power value of the center frequency point through the target spectrum analyzer; and using the power value of the center frequency point as the power information of the wireless communication module.

[0074] In this embodiment, the terminal identifies the transmission frequency point of the wireless communication module and the transmission attenuation value of the wireless communication module based on the current signal transmission parameters. Then, the terminal randomly selects a single transmission frequency point from each transmission frequency point, and replaces the center frequency point of the spectrum analyzer with the transmission frequency point. Then, the terminal automatically configures other parameters of the spectrum analyzer based on the historical operation data of the frequency analyzer to obtain the target spectrum analyzer. The parameters that need to be configured include analysis mode, modulation mode, reference level, center frequency point and other parameters.

[0075] Based on the transmission attenuation value, the target spectrum analyzer is used to identify the power value of the center frequency. Finally, the terminal uses the power value of the center frequency as the power information of the wireless communication module.

[0076] Based on the above solution, by automatically setting the analysis mode, modulation mode, reference level, center frequency and other parameters of the spectrum analyzer, the inefficient process of manual configuration is avoided, and the efficiency of calibration preparation of the wireless communication module is greatly improved.

[0077] Optionally, based on the power information, the signal calibration information of the wireless communication module is identified through a calibration strategy, including: obtaining a target power value and a transmission frequency of the wireless communication module, and identifying the power value of the center frequency and the size relationship between the power value and the target power value; based on the size relationship, adjusting the transmission attenuation value to obtain a first transmission attenuation value, and when the first transmission attenuation value is greater than a preset transmission attenuation value, replacing the transmission attenuation value with the first transmission attenuation value, returning to execute the power step of identifying the center frequency through a target spectrum analyzer based on the transmission attenuation value, until the first transmission attenuation value is not greater than the preset transmission attenuation value, and using the power value of the center frequency obtained by the last iteration and the first transmission attenuation value as the sub-signal calibration information of the wireless communication module; adjusting the transmission frequency of the wireless communication module through a transmission frequency adjustment strategy to obtain each new transmission frequency, and identifying the sub-signal calibration information corresponding to each new transmission frequency; using the sub-signal calibration information corresponding to all new transmission frequencies and the sub-signal calibration information corresponding to the transmission frequency of the wireless communication module as the signal calibration information of the wireless communication module.

[0078] In this embodiment, the terminal obtains the target power value and the transmission frequency of the wireless communication module, and identifies the relationship between the power value of the center frequency point and the target power value.

[0079] Among them, the wireless module transmission frequency point is F1 and the transmission attenuation value is A0.

[0080] Read the power value P of the center frequency corresponding to the transmitting frequency point on the spectrum analyzer, and compare it with the target power value P0;

[0081] a) When P>P0, increase the attenuation value, and the adjustment value is |P-P0| (rounded off);

[0082] b) When P<P0, reduce the attenuation value and adjust the value to |P-P0| (round off);

[0083] Based on the magnitude relationship, the terminal adjusts the transmission attenuation value to obtain the first transmission attenuation value, and when the first transmission attenuation value is greater than the preset transmission attenuation value, the first transmission attenuation value replaces the transmission attenuation value, and returns to execute the power step of identifying the center frequency point through the target spectrum analyzer based on the transmission attenuation value, until the first transmission attenuation value is not greater than the preset transmission attenuation value, and the power value of the center frequency point obtained by the last iteration and the first transmission attenuation value are used as the sub-signal calibration information of the wireless communication module. Among them, the first transmission attenuation value is 0.5dB, and the above process is that the terminal iteratively detects the adjusted attenuation value until the adjusted attenuation value |P-P0|≤0.5dB, the terminal records the first transmission attenuation value at this moment, and the power value of the center frequency point at this moment, and obtains the sub-signal calibration information.

[0084] The terminal adjusts the transmission frequency of the wireless communication module through the transmission frequency adjustment strategy, obtains each new transmission frequency, and identifies the sub-signal calibration information corresponding to each new transmission frequency. The terminal uses the sub-signal calibration information corresponding to all new transmission frequencies and the sub-signal calibration information corresponding to the transmission frequency of the wireless communication module as the signal calibration information of the wireless communication module. The transmission frequency adjustment strategy is to adjust the transmission frequency in steps of 5MHz to obtain the sub-signal calibration information corresponding to each adjusted transmission frequency. The specific process of identifying the sub-signal calibration information corresponding to each new transmission frequency will be described in detail later.

[0085] Based on the above scheme, the attenuation value and power value lower than the preset attenuation threshold are iteratively searched to ensure that the sub-signal calibration information of each transmission frequency meets the calibration requirements of the wireless communication module, and by stepping in 5MHz, the sub-signal calibration information of different transmission frequencies is identified, which not only reduces the number of iterations and improves the calibration efficiency, but also ensures that the corresponding relationship between the transmission frequency and power value and the attenuation value can be identified, thereby improving the calibration accuracy.

[0086] Optionally, identifying sub-signal calibration information corresponding to each new transmission frequency includes: configuring the transmission frequency of the wireless communication module based on each new transmission frequency, and re-acquiring new signal transmission parameters of each new wireless communication module; replacing the current signal transmission parameters with each new signal transmission parameter, and replacing the wireless communication module with each new wireless communication module, returning to execute the step of identifying the power information of the wireless communication module based on the current signal transmission parameters to obtain sub-signal calibration information of each new wireless communication module; using each sub-signal calibration information as the sub-signal calibration information corresponding to the new transmission frequency of each new wireless communication module.

[0087] In this embodiment, the terminal configures the transmission frequency of the wireless communication module based on each new transmission frequency, and re-acquires the new signal transmission parameters of each new wireless communication module. Then, the terminal replaces the current signal transmission parameters with each new signal transmission parameter, and replaces the wireless communication module with each new wireless communication module, and returns to execute the step of identifying the power information of the wireless communication module based on the current signal transmission parameter to obtain the sub-signal calibration information of each new wireless communication module. Finally, the terminal uses each sub-signal calibration information as the sub-signal calibration information corresponding to the new transmission frequency of each new wireless communication module.

[0088] Based on the above scheme, the wireless communication module is adjusted by the new transmission frequency to re-identify the sub-signal calibration information corresponding to each new transmission frequency, thereby improving the accuracy of identifying the sub-signal calibration information corresponding to each new transmission frequency.

[0089] Optionally, based on the calibration information of each signal, an attenuation value calibration fitting table of the wireless communication module is generated, including: based on the sub-signal calibration information corresponding to each transmission frequency, a signal calibration information distribution table is generated, and based on the signal calibration information distribution table, through a unit step fitting strategy, the unit signal calibration information corresponding to the unit transmission frequency corresponding to each unit step is fitted; the fitting attenuation value of each unit signal calibration information is identified, and based on the fitting attenuation value corresponding to each unit transmission frequency, an attenuation value calibration fitting table of the wireless communication module is generated.

[0090] In this embodiment, the terminal generates a signal calibration information distribution table based on the sub-signal calibration information corresponding to each transmission frequency, wherein the columns of the signal calibration information distribution table are each transmission frequency, and the rows of the signal calibration information distribution table are each sub-signal calibration information.

[0091] Based on the signal calibration information distribution table, the unit signal calibration information corresponding to the unit transmission frequency corresponding to each unit step is fitted through the unit step fitting strategy. The unit step fitting strategy is a fitting method corresponding to the explicit fitting method, which fits the sub-signal calibration information corresponding to the unit transmission frequency step between 5MHz. The unit transmission frequency step is 1MHz.

[0092] Then, the terminal identifies the fitting attenuation value of each unit signal calibration information, and generates an attenuation value calibration fitting table for the wireless communication module based on the fitting attenuation value corresponding to each unit transmission frequency, wherein each unit transmission frequency corresponds to a fitting attenuation value and a fitting power value.

[0093] Based on the above scheme, the sub-signal calibration information corresponding to different unit transmission frequencies is identified by unit step fitting, which ensures the accuracy of the obtained sub-signal calibration information and improves the efficiency of obtaining the attenuation value calibration fitting table.

[0094] Optionally, the wireless communication module is calibrated through the attenuation value calibration fitting table to obtain the target wireless communication module, including: based on each unit signal calibration information, identifying the fitting power value corresponding to each fitting attenuation value, and obtaining the transmission power value of each actual transmission frequency point of the wireless communication module; based on the fitting power value corresponding to each fitting attenuation value, identifying the fitting attenuation value corresponding to each transmission power value, and replacing the current attenuation value of each actual transmission frequency point with each fitting attenuation value to obtain the initial target wireless communication module; among the actual transmission frequency points of the initial target wireless communication module, randomly selecting a preset number of transmission frequency points to be tested, and verifying the accuracy of each transmission frequency point to be tested through a preset verification procedure; in the case where the accuracy of the transmission frequency point to be tested is lower than the accuracy threshold, replacing the wireless communication module with the initial target wireless communication module, and returning to execute the step of obtaining the calibration strategy of the wireless communication module and the current signal transmission parameter step of the wireless communication module, until there is no transmission frequency point to be tested with an accuracy lower than the accuracy threshold, and the initial target wireless communication module obtained by the last iteration is used as the target wireless communication module.

[0095] In this embodiment, the terminal identifies the fitting power value corresponding to each fitting attenuation value based on the calibration information of each unit signal, and obtains the transmission power value of each actual transmission frequency point of the wireless communication module. Then, based on the fitting power value corresponding to each fitting attenuation value, the terminal identifies the fitting attenuation value corresponding to each transmission power value, and replaces the current attenuation value of each actual transmission frequency point with each fitting attenuation value to obtain the initial target wireless communication module.

[0096] Among the actual transmitting frequency points of the initial target wireless communication module, the terminal randomly selects a preset number of transmitting frequency points to be tested, and verifies the accuracy of each transmitting frequency point to be tested through a preset verification program. The preset verification program is a conventional accuracy verification program for the wireless communication module, and this scheme does not make redundant descriptions. The preset number is the number preset in the terminal. Then, the terminal also presets an accuracy threshold. In the case where the accuracy of the transmitting frequency point to be tested is lower than the accuracy threshold, the terminal replaces the wireless communication module with the initial target wireless communication module, and returns to execute the calibration strategy for obtaining the wireless communication module, and the current signal transmission parameter step of the wireless communication module, until there is no transmitting frequency point to be tested whose accuracy is lower than the accuracy threshold, and the initial target wireless communication module obtained in the last iteration is used as the target wireless communication module.

[0097] Based on the above solution, the calibration accuracy of the calibrated wireless communication module is identified through a verification program, so that the wireless communication module is iteratively calibrated to ensure the calibration accuracy of the target wireless communication module.
