The environment parameters of the target device include parameters of the field environment where the target device is located, parameters of the network environment, and the like. The environment parameter is used to describe an environmental condition of an environment to which the target device belongs. The first radio frequency parameter is a current radio frequency parameter of the target device. The second radio frequency parameters of the target device corresponding to different environmental conditions are different, and the second radio frequency parameters are theoretically optimal radio frequency parameters of the target device under the environmental conditions. The target device can be any device in any field, for example, the target device is a measurement and control field, and can be a mobile communication test instrument, a comprehensive tester, a programmable power supply and the like. And calibrating the target equipment, namely updating the existing first radio frequency parameters of the target equipment into the second radio frequency parameters which are optimal in theory.

The linear regression process may be any fitting method commonly used, such as a least squares fitting method, although the linear regression process may be implemented by some software, such as excel or matlab. And inputting the environment parameter and the second radio frequency parameter into the software by taking the environment parameter as an independent variable and taking the second radio frequency parameter as an independent variable, so that a regression result can be output. If the regression result is a function, then a simulation model is constructed according to the regression result, and the simulation model can be constructed by taking the function as a main body and adding other requirements. Other requirements, such as the need to present the data in an image, then the simulation model needs to add the data to image conversion relationship based on the function. The first logic diagram is the logic expressed by the simulation model, and can be understood as a mapping relation or a functional expression equivalent to the simulation model. The simulation model is constructed based on the regression results, and the first logic diagram is extracted from the simulation model. The first logic diagram may be one to which the above "other requirements" class is added based on the regression results. The first logic diagram is optimized according to the calibration result, and the first logic diagram can be corrected according to the calibration result. Training the simulation model according to the optimized first logic diagram can be understood as updating model parameters of the simulation model by a back propagation method according to the optimized first logic diagram.
According to the embodiment of the disclosure, the calibration of the target equipment can be realized by means of the model, and a calibration instrument is not needed, so that the cost of the calibration equipment is reduced, and meanwhile, the accuracy of the calibration equipment can be improved by improving the accuracy of the model.
According to the technical scheme provided by the embodiment of the disclosure, training parameters are acquired, first radio frequency parameters and environment parameters of target equipment are acquired, calibration equipment is utilized to calibrate the training parameters to obtain calibration results, linear regression processing is conducted on the training parameters and the calibration results to obtain regression results, a simulation model is built according to the regression results, a first logic diagram is extracted from the simulation model, the first logic diagram is optimized according to the calibration results, the simulation model is trained according to the optimized first logic diagram, the environment parameters are input into the simulation model, second radio frequency parameters are output, and when the difference value between the second radio frequency parameters and the first radio frequency parameters is larger than a preset threshold value, the target equipment is calibrated based on the second radio frequency parameters and the first radio frequency parameters. By adopting the technical means, the problems of high calibration cost and low accuracy of the equipment in the prior art are solved, the cost of the calibration equipment is further reduced, and the accuracy of the calibration equipment is improved.
The method comprises the steps of obtaining a regression result by carrying out linear regression on training parameters and a calibration result, constructing a simulation model according to the regression result, constructing a simulation network model by using the simulation model and a neural network model, training the simulation network model by using the training parameters, extracting a second logic diagram from the trained simulation network model, optimizing the second logic diagram according to the calibration result, retraining the simulation network model according to the optimized second logic diagram, inputting environment parameters into the simulation network model, and outputting second radio frequency parameters.
And constructing a simulation network model by using the simulation model and the neural network model, wherein the simulation model can be connected with the neural network model. According to the embodiment of the disclosure, the simulation network model is trained twice, so that the accuracy of the trained model is improved. The second logic diagram is similar to the first logic diagram and optimizing the second logic diagram is similar to optimizing the first logic diagram. Because the simulation model constructed by using the mathematical method is difficult to improve after the accuracy reaches a certain degree, but the neural network model does not have the problem. The neural network model can be trained through a large number of machine learning, so that the accuracy of the model can be improved as much as possible. The disclosed embodiments utilize neural network models to improve the accuracy of simulation models. Specifically, in the simulation network model, the output of the simulation model is an input of the neural network model, and the neural network model is the second radio frequency parameter (although the simulation model is established based on a mapping relationship between the environment parameter and the second radio frequency parameter, in practical application, the output of the simulation model may not be the second radio frequency parameter).
It should be noted that the neural network model may be any of the commonly used neural network models, such as Faster-RCNN. The training methods in this disclosure are all methods similar to deep learning training.
The training method comprises the steps of determining a training data set corresponding to training parameters according to an optimized second logic diagram, training the simulation network model by using the training data set to update parameters of the simulation model in the simulation network model under the condition of freezing the simulation network model in the whole training process, training the simulation network model by using the training data set to update parameters of the neural network model in the simulation network model under the condition of freezing the simulation model in the second round, and training the simulation network model by using the training data set to update parameters of the neural network model in the simulation network model in the third round.
According to the optimized second logic diagram, a training data set corresponding to the training parameters is determined, for example, the second radio frequency parameters corresponding to a certain environmental parameter are not right, and then the correct second radio frequency parameters corresponding to the certain environmental parameter can be marked by using the optimized second logic diagram. The training data set can be regarded as updated training parameters. This step is similar to correcting the second radio frequency parameter for which a certain environmental parameter corresponds in calibrating the training parameter using the calibration device. But because the second logic diagram is extracted from the trained simulated network model, the second logic diagram is more optimal than the calibration device.
And retraining the simulation network model according to the optimized second logic diagram, wherein the retraining comprises three rounds of training. The first training round, in the case of freezing a neural network model, trains the simulation network model using the training dataset, which can be understood as training only the simulation model, the step being used to adjust the parameters of the simulation model, the second training round, in the case of freezing a simulation model, trains the simulation network model using the training dataset, which can be understood as training only the neural network model, the step being the most common training of the neural network model, and the third training round, training the simulation network model using the training dataset, which is training both the simulation model and the neural network model, the step being used to fine tune the parameters of the simulation network model.
After retraining the simulation network model according to the optimized second logic diagram, the method further comprises inputting the environmental parameters into a neural network model in the simulation network model, and outputting second radio frequency parameters.
The simulation model in the embodiment of the present disclosure is only used in retraining, and assists in adjusting parameters of the neural network model (the embodiment of the present disclosure is different from the above embodiment in that the neural network model is used as a main body, the simulation model is used as an auxiliary body, the above embodiment is used as an auxiliary body, and the simulation model is used as a main body, so that the method has the advantage of helping the neural network model to converge as soon as possible.
The method comprises the steps of obtaining training parameters, obtaining first radio frequency parameters and environment parameters of target equipment, training a neural network model by using the training parameters, enabling the neural network model to learn and store corresponding relations between the environment parameters and second radio frequency parameters, calibrating the training parameters by using calibration equipment to obtain a calibration result, extracting a third logic diagram from the neural network model, optimizing the third logic diagram according to the calibration result, retraining the neural network model according to the optimized third logic diagram, inputting the environment parameters into the neural network model, outputting the second radio frequency parameters, and calibrating the target equipment based on the second radio frequency parameters and the first radio frequency parameters when the difference value between the second radio frequency parameters and the first radio frequency parameters is larger than a preset threshold value.
The third logic diagram is similar to the first logic diagram and will not be described again. In the prior art, the radio frequency parameters of the target equipment are calibrated through the calibration equipment, the neural network model is introduced for the first time, and the second radio frequency parameters corresponding to the environmental parameters are determined through the trained neural network model, so that the radio frequency parameters of the target equipment are calibrated.
Before training the neural network model by using the training parameters to enable the neural network model to learn and store the corresponding relation between the environmental parameters and the second radio frequency parameters, the method further comprises the steps of obtaining equipment information of a plurality of equipment of the same type in the same application field as the target equipment, and updating the model parameters of the neural network model according to the equipment information of the plurality of equipment.
If training is performed on the neural network model by directly using the training parameters, the training time may be long, and in order to improve the training efficiency, the embodiment of the disclosure updates the model parameters of the neural network model according to the device information of the plurality of devices before training the neural network model. Updating the model parameters of the neural network model according to the device information of the plurality of devices may be understood as updating the values of the model parameters of the neural network model into the intervals corresponding to the target devices. The equipment information comprises information of application fields of equipment, types of the equipment, operating parameters of the equipment and the like, such as a theoretical interval of operating frequency of the equipment. By the technical means, the convergence rate of the neural network model in training can be improved.
In order to improve the accuracy of the trained neural network model, embodiments of the present disclosure retrain the neural network model. The calibration result is a second parameter value recommended by the calibration device.

S parameters including characteristic impedance, crosstalk, insertion loss, return loss, etc. For example, the embodiments of the present disclosure may adjust the first s-parameter by adjusting the operating circuit of the target device, thereby calibrating the first rf parameter based on the second rf parameter. The target device can select different circuits during working, and then select the circuit with the second s parameter. The signal gains corresponding to the different circuits are different, and the most suitable circuit can be selected according to the second signal gain. The first transmit signal power may also be adjusted based on the second transmit signal power, etc.
It should be noted that any one of the first radio frequency parameter and the second radio frequency parameter in the embodiments of the present disclosure may correspond to a value of one interval. For example, the second transmit signal power may be an interval of transmit signal power.
In an alternative embodiment, the environment parameters of the target device are acquired, the light wave reflection constraint condition, the light wave scattering constraint condition, the light wave refraction constraint condition and the light wave diffraction constraint condition are established based on the light wave reflection principle, the light wave scattering principle, the light wave refraction principle and the light wave diffraction principle respectively, the light wave propagation energy function is established based on the light wave propagation energy loss minimum as a criterion, the mathematical model is constructed based on the light wave reflection constraint condition, the light wave scattering constraint condition, the light wave refraction constraint condition, the light wave diffraction constraint condition and the light wave propagation energy function, the environment parameters are input into the mathematical model, the second working wavelength of the target device is output, the second working frequency of the target device is determined according to the working wavelength, and when the difference value between the second working frequency and the first working frequency is larger than a preset threshold value, the target device is calibrated based on the second working frequency and the first working frequency.
The second radio frequency parameter comprises a second operating frequency, and the first radio frequency parameter comprises a first operating frequency.
Embodiments of the present disclosure pertain to the idea of mathematical modeling. The propagation capabilities of different wavelengths in an environment vary, including reflection, scattering, refraction, diffraction, etc. In order to enhance the propagation capability of working waves of target equipment in the environment and reduce loss in the propagation process, the embodiment of the disclosure establishes a light wave reflection constraint condition based on a light wave reflection principle, establishes a light wave scattering constraint condition based on a light wave scattering principle, establishes a light wave refraction constraint condition based on a light wave refraction principle, and establishes a light wave diffraction constraint condition based on a light wave diffraction principle. The wavelength of the working wave of the target equipment can be controlled within a certain interval through the constraint condition, and then the second working wavelength of the target equipment is solved from the interval according to the light wave propagation energy function. Since the wavelength and the frequency satisfy certain conditions, the second operating frequency of the target device can be determined according to the operating wavelength. The environmental parameters include all information of the environment in which the target device is located, such as which obscuration objects affect the propagation of the light waves are located in the environment in which the target device is located, and the position and size of the obscuration objects.
In an alternative embodiment, the environment parameters of the target device are acquired, the parameters of at least one of the optimal voltage, the optimal current and the anti-interference information of the target device are determined according to the environment parameters, the optimal transmitting signal power of the target device is determined based on the parameters of at least one of the optimal voltage, the optimal current and the anti-interference information, the second radio frequency parameters comprise the optimal transmitting signal power, the dividing value is obtained by dividing the optimal transmitting signal power by the current transmitting signal power, the optimal signal gain is determined according to the dividing value, the second radio frequency parameters comprise the optimal signal gain, the first radio frequency parameters comprise the current transmitting signal power, and the working circuit of the target device is determined according to the optimal signal gain.
The target device may operate in different environments or with different target device operation, and the allowed transmit signal power of the target device may vary, or the optimal transmit signal power of the target device may vary, taking into account the power consumption of the device. In order to solve the above technical problems, embodiments of the present disclosure determine, through environmental parameters, an optimal voltage, or an optimal current, or anti-interference information of a target device. Since the internal resistance of the target device is known, the optimal transmit signal power of the target device can be determined from the relationship of voltage, current, resistance, and power. The immunity information is used to indicate the immunity capability that the transmit signal power of the target device should have. In some cases, if the target device requires stronger immunity to interference, the transmit signal power of the target device should be increased, and if the target device does not require stronger immunity to interference, the transmit signal power of the target device should be appropriately reduced according to the specific circumstances. The optimal transmit signal power of the target device is also determined based on the immunity information.
The embodiment of the disclosure can provide a plurality of gain circuits for the target equipment, so as to provide a plurality of gains for the target equipment. The division value obtained by dividing the optimal transmission signal power by the current transmission signal power can be understood as the gain required by the target device, that is, the optimal signal gain. The current signal gain is the gain being used by the target device at the current time. After the optimal signal gain, the operating circuit of the target device may be determined based on the optimal signal gain. Determining the operational circuitry of the target device is also a method of calibrating the target device.
Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein.

By adopting the technical means, the problems of high calibration cost and low accuracy of the equipment in the prior art are solved, the cost of the calibration equipment is further reduced, and the accuracy of the calibration equipment is improved.

According to the embodiment of the disclosure, the simulation network model is trained twice, so that the accuracy of the trained model is improved. The second logic diagram is similar to the first logic diagram and optimizing the second logic diagram is similar to optimizing the first logic diagram. Because the simulation model constructed by using the mathematical method is difficult to improve after the accuracy reaches a certain degree, but the neural network model does not have the problem. The neural network model can be trained through a large number of machine learning, so that the accuracy of the model can be improved as much as possible. The disclosed embodiments utilize neural network models to improve the accuracy of simulation models. Specifically, in the simulation network model, the output of the simulation model is an input of the neural network model, and the neural network model is the second radio frequency parameter (although the simulation model is established based on a mapping relationship between the environment parameter and the second radio frequency parameter, in practical application, the output of the simulation model may not be the second radio frequency parameter).
It should be noted that the neural network model may be any of the commonly used neural network models, such as Faster-RCNN. The training methods in this disclosure are all methods similar to deep learning training.
Optionally, the construction module 303 is further configured to determine a training data set corresponding to the training parameters according to the optimized second logic diagram, to train the simulation network model using the training data set to update parameters of the simulation model in the simulation network model in case of freezing the simulation network model in the first round of training, to train the simulation network model using the training data set to update parameters of the simulation network model in case of freezing the simulation model in the second round of training, and to train the simulation network model using the training data set in the third round of training to update parameters of the simulation model and the simulation network model in the third round of training.
According to the optimized second logic diagram, a training data set corresponding to the training parameters is determined, for example, the second radio frequency parameters corresponding to a certain environmental parameter are not right, and then the correct second radio frequency parameters corresponding to the certain environmental parameter can be marked by using the optimized second logic diagram. The training data set can be regarded as updated training parameters. This step is similar to correcting the second radio frequency parameter for which a certain environmental parameter corresponds in calibrating the training parameter using the calibration device. But because the second logic diagram is extracted from the trained simulated network model, the second logic diagram is more optimal than the calibration device.
And retraining the simulation network model according to the optimized second logic diagram, wherein the retraining comprises three rounds of training.

In the prior art, the radio frequency parameters of the target equipment are calibrated through the calibration equipment, the neural network model is introduced for the first time, and the second radio frequency parameters corresponding to the environmental parameters are determined through the trained neural network model, so that the radio frequency parameters of the target equipment are calibrated.
Optionally, the first calibration module 302 is further configured to acquire device information of a plurality of devices of a same type in a same application domain as the target device, and update model parameters of the neural network model according to the device information of the plurality of devices.
If training is performed on the neural network model by directly using the training parameters, the training time may be long, and in order to improve the training efficiency, the embodiment of the disclosure updates the model parameters of the neural network model according to the device information of the plurality of devices before training the neural network model.

The target device can select different circuits during working, and then select the circuit with the second s parameter. The signal gains corresponding to the different circuits are different, and the most suitable circuit can be selected according to the second signal gain. The first transmit signal power may also be adjusted based on the second transmit signal power, etc.

Embodiments of the present disclosure pertain to the idea of mathematical modeling. The propagation capabilities of different wavelengths in an environment vary, including reflection, scattering, refraction, diffraction, etc. In order to enhance the propagation capability of working waves of target equipment in the environment and reduce loss in the propagation process, the embodiment of the disclosure establishes a light wave reflection constraint condition based on a light wave reflection principle, establishes a light wave scattering constraint condition based on a light wave scattering principle, establishes a light wave refraction constraint condition based on a light wave refraction principle, and establishes a light wave diffraction constraint condition based on a light wave diffraction principle. The wavelength of the working wave of the target equipment can be controlled within a certain interval through the constraint condition, and then the second working wavelength of the target equipment is solved from the interval according to the light wave propagation energy function. Since the wavelength and the frequency satisfy certain conditions, the second operating frequency of the target device can be determined according to the operating wavelength. The environmental parameters include all information of the environment in which the target device is located, such as which obscuration objects affect the propagation of the light waves are located in the environment in which the target device is located, and the position and size of the obscuration objects.

The target device may operate in different environments or with different target device operation, and the allowed transmit signal power of the target device may vary, or the optimal transmit signal power of the target device may vary, taking into account the power consumption of the device. In order to solve the above technical problems, embodiments of the present disclosure determine, through environmental parameters, an optimal voltage, or an optimal current, or anti-interference information of a target device. Since the internal resistance of the target device is known, the optimal transmit signal power of the target device can be determined from the relationship of voltage, current, resistance, and power. The immunity information is used to indicate the immunity capability that the transmit signal power of the target device should have. In some cases, if the target device requires stronger immunity to interference, the transmit signal power of the target device should be increased, and if the target device does not require stronger immunity to interference, the transmit signal power of the target device should be appropriately reduced according to the specific circumstances. The optimal transmit signal power of the target device is also determined based on the immunity information.
The embodiment of the disclosure can provide a plurality of gain circuits for the target equipment, so as to provide a plurality of gains for the target equipment. The division value obtained by dividing the optimal transmission signal power by the current transmission signal power can be understood as the gain required by the target device, that is, the optimal signal gain. The current signal gain is the gain being used by the target device at the current time. After the optimal signal gain, the operating circuit of the target device may be determined based on the optimal signal gain. Determining the operational circuitry of the target device is also a method of calibrating the target device.
