Description

Calibration method, device and system

Technical Field

The present application relates to the field of data processing technologies, and in particular, to a calibration method, device and system.

Background

Radio Frequency (RF) modules are typically assembled from a plurality of devices. There are differences or fluctuations in performance parameters for different batches of devices. Therefore, the RF module is usually calibrated after the RF module is assembled. Here, "the RF module performs calibration" is to collectively test the performance of a plurality of devices in the RF module.

Since there are differences or fluctuations in performance parameters for different batches of devices, and there are also individual differences between different devices of the same batch, RF module calibration is typically performed after multiple devices are assembled into an RF module. However, since the fluctuation of the device performance parameters affects the accuracy of the calibration result of the RF module, the accuracy of the calibration result obtained by calibrating the RF module after the RF module is assembled is poor. The RF module is calibrated after being assembled, and the calibration efficiency is low.

Disclosure of Invention

The embodiment of the application provides a calibration method, a calibration device and a calibration system, which can improve the accuracy and the calibration efficiency of a calibration result of an RF module.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, an execution subject of the calibration method may be a first calibration device. The following description will be given taking as an example that the execution subject is the first calibration apparatus. The method comprises the following steps: the first calibration device acquires identification information of a target device in the RF module. The first calibration device acquires first data according to the identification information of the target device. Wherein the RF module includes a plurality of devices including the target device. The first data includes calibration data for compensating for operating performance of the target device. And calibrating the RF module according to the calibration data to obtain the calibration result of the RF module. Wherein the calibration result of the RF module comprises an operating parameter of the RF module.

Here, the target device may be a power amplifier, a filter, or the like. In the case where the target device is a power amplifier, the calibration data is indicative of the operating voltage and operating current of the power amplifier. In the case where the target device is a filter, the calibration data is used to indicate the standing wave value of the filter.

According to the calibration method provided by the embodiment of the application, the first calibration device can acquire the calibration data of the target device through the identification information of the target device in the RF module, and then acquire the calibration result of the RF module according to the calibration data of the target device, so that the RF module does not need to be subjected to centralized calibration after being assembled, and the calibration efficiency of the RF module is improved. The calibration data of the target device can accurately compensate the working performance of the target device, so that the problem of low accuracy of the calibration result of the RF module caused by the difference or fluctuation of the performance parameters of the target device is solved.

In one possible design, obtaining the first data according to the identification information of the target device includes: after the identification information of the target device is transmitted to the server, first data from the server is received. The server stores the corresponding relation between the identification information of the target device and the first data.

Therefore, the first calibration equipment can obtain the first data of the device granularity, namely the first data of the target device, from the server according to the identification information of the target device, and does not need to perform centralized calibration on the RF module, thereby avoiding the problems of low calibration efficiency and long time consumption of the RF module in the related technology.

In one possible design, calibrating the RF module according to the calibration data to obtain a calibration result of the RF module includes: after the position information of the target device in the RF module is obtained, the RF module is calibrated according to the calibration data of the target device and the position information of the target device, and the calibration result of the RF module is obtained.

In this way, when the target device is a plurality of devices in the RF module or a part of the devices in the RF module, and the RF module operates using the target device, the first calibration device can calibrate the target device in a part of the area of the RF module according to the position of the target device in the RF module and by combining the calibration data of the target device in the position, so as to obtain a corresponding calibration result. Because the target devices with different position information have different functions in the RF module, and the calibration result of the RF module is calculated by combining the position information of the target devices, the accuracy of the calibration result of the RF module can be ensured, and the operation efficiency of the calibration result of the RF module can be improved.

That is, in the case where the target device having the above-mentioned position information can realize a certain function of the RF module (e.g., a radio signal transmitting function of the RF module, a radio signal receiving function of the RF module), the first calibration device can calculate calibration data of the target device based on the position information of the target device to obtain a calibration result of the corresponding function of the RF module.

Detailed Description

The terms "first" and "second" and the like in the description and drawings of the present application are used for distinguishing different objects or for distinguishing different processes for the same object, and are not used for describing a specific order of the objects. Furthermore, the terms "including" and "having," and any variations thereof, as referred to in the description of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In order to make the present application clearer, a brief description of some concepts and process flows mentioned in the present application will be given first.

Typically, an RF module includes one or more devices such as power amplifiers, filters, attenuators, couplers, and the like. The devices included in the RF module may be classified into two types, i.e., a chip-type device and a non-chip-type device. The chip-type device may be a device implemented in a chip form, such as a power amplifier. The off-chip type device may be a device implemented in a stand-alone device, such as a filter or the like. The RF module realizes transmission of a radio signal by converting a wired electric signal into a radio signal. The RF module can also convert radio signals into wired electric signals to realize the reception of the radio signals. In the practical application process, the RF module may be a radio frequency module in a mobile phone, or a radio frequency unit in a base station.

Since there are differences or fluctuations in performance parameters for different batches of devices, and there are also individual differences between different devices of the same batch, RF module calibration is typically performed after multiple devices are assembled into an RF module. However, since the fluctuation of the device performance parameters affects the accuracy of the calibration result of the RF module, the accuracy of the calibration result obtained by calibrating the RF module after the RF module is assembled is poor. In addition, calibration is inefficient, takes a long time, and affects manufacturing costs.

In view of this, the present application provides a calibration method, and first, a calibration system to which the calibration method of the present application is applied will be described. Referring to fig. 1, the calibration system includes a first calibration device 10, a second calibration device 20, and a server 30. The first calibration device 10 and the server 30 are connected in a wired or wireless manner for data transmission, and the second calibration device 20 and the server 30 are connected in a wired or wireless manner for data transmission. Fig. 1 is a schematic diagram, and does not constitute a limitation to an applicable scenario of the calibration method according to the embodiment of the present application.

The first calibration device 10 is configured to calibrate the RF module, and obtain a calibration result of the RF module. The first calibration device 10 includes a transceiver, an industrial personal computer, and the like. Wherein the transceiver is used for the first calibration device 10 to exchange information with other devices, and the transceiver can be a transmitter, a receiver, etc. Optionally, the first calibration device 10 further comprises an imaging unit. The imaging unit may be a camera, a scanner, a machine vision mechanism, or the like. The imaging unit is capable of acquiring identification information of the device.

And the second calibration equipment 20 is used for calibrating the device in the RF module to obtain calibration data of the device. The second calibration device 20 includes a power meter, a signal source, a spectrometer, a network analyzer, a radio frequency switch, a programmable power supply, a device carrier, and the like.

And the server 30 is used for storing data. Here, the data stored in the server 30 may be calibration data of the device, operating parameters of the device in an aging state, a joint mapping table, and the like. The joint mapping table is used for storing the corresponding relation between the position information and the first indication information. The location information is used to indicate the location of the device in the RF module. The first indication information is used for indicating a storage area of calibration results of different indexes of the RF module in the RF module. The server 30 may refer to one server or a server cluster. The server 30 may be considered a device that is accessible at any time by the first calibration device 10 and the second calibration device 20.

The calibration system and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application.

Next, the calibration method provided in the embodiment of the present application is specifically described.

The embodiment of the application provides a calibration method, which is applied to the calibration process of an RF module. Referring to fig. 2, the calibration method includes the steps of:

s201, the first calibration equipment acquires identification information of a target device in the RF module.

Wherein the RF module includes a plurality of devices. The target device may be any one of the devices described above.

The target device may be a device that realizes a certain function of the RF module in cooperation with each other among the above-described devices. Here, a certain function of the RF module refers to a function that the target devices realize in cooperation with each other. For example, a radio signal transmitting function or a radio signal receiving function of the RF module. Specifically, the target device for implementing the "radio signal transmission function" may be: the devices in the signal transmission path in the RF module, the target devices for implementing the "radio signal reception function" may be: devices in the signal receiving path in the RF module.

The target device may also be a device involved in calibrating a certain index of the RF module. The certain indicator of the RF module may be, for example, but not limited to, at least one of: temperature, transmit frequency, receive frequency, etc. Specifically, when the "temperature" index of a certain region of the RF module is calibrated, the device located in the region is the target device. Under the condition of calibrating the index of the 'transmission frequency' of the RF module, a device influencing the transmission frequency of a radio signal in the RF module is a target device. Under the condition of calibrating the index of the receiving frequency of the RF module, a device influencing the receiving frequency of the radio signal in the RF module is a target device.

The identification information is used to uniquely identify a target device. The identification information may be, for example, but not limited to, any of: one-dimensional code, two-dimensional code, barcode, Radio Frequency Identification (RFID). Here, RFID is also called an electronic tag. In practical applications, usually in a radio frequency single board testing process of the RF module, the first calibration device may identify and read identification information of the target device through an imaging unit (e.g., a camera, a scanner, or a machine vision mechanism).

S202, the first calibration equipment acquires first data according to the identification information of the target device.

Wherein the first data comprises calibration data of the target device, the calibration data of the target device being used to compensate for the operating performance of the target device.

For example, in the case that the target device is a power amplifier, the calibration data is used to indicate an operating voltage and an operating current of the power amplifier to compensate the transmission power of the power amplifier, such as to make the transmission power of the power amplifier in an operating state a target power value.

For another example, where the target device is a filter, the calibration data is used to indicate a standing wave value of the filter to compensate for the degree of matching of the filter to other devices in the RF module, e.g., to enable the degree of matching of the filter to other devices of the RF module to reach a target value in an operating state.

The "correspondence between the identification information of the target device and the first data" is prestored in a storage medium of the first calibration device or a device such as a server, so that the first calibration device can read the first data at any time. Taking the server storage "the corresponding relationship between the identification information of the target device and the first data" as an example, referring to fig. 3, the specific implementation manner of S202 is as follows:

s2021, the first calibration equipment sends the identification information of the target device to the server. Accordingly, the server receives identification information of the target device from the first calibration apparatus.

The server stores the corresponding relation between the identification information of the target device and the first data. For example, the server may store the correspondence between the identification information of the target device and the first data in the form of a table.

S2022, the server determines first data corresponding to the identification information of the target device.

Here, since the server stores the corresponding relationship between the identification information of the target device and the first data, the server may query the pre-stored information according to the identification information of the target device, and then obtain the corresponding first data.

S2023, the server sends the first data to the first calibration device. Accordingly, the first calibration device receives the first data from the server.

Therefore, the first calibration equipment can obtain the first data of the device granularity, namely the first data of the target device, from the server according to the identification information of the target device, and does not need to carry out centralized calibration on the RF module, thereby avoiding the problems of low calibration efficiency and long time consumption in the related technology.

S203, the first calibration equipment calibrates the RF module according to the calibration data to obtain a calibration result of the RF module.

The calibration result of the RF module includes the operating parameter of the RF module, for example, the calibration result of the RF module may be the calibration result of the operating parameter of the RF module under different standards.

Illustratively, taking the index "temperature" as an example, the calibration data includes "operating voltage and operating current of the power amplifier at different temperatures" and "standing wave value of the filter at different temperatures". The first calibration device calculates the working voltage and working current of the power amplifier at different temperatures and the standing wave value of the filter at different temperatures to obtain the working parameters of the RF module at the temperature index, namely the working parameters of the RF module at different temperatures. Therefore, the RF module can determine the working parameter corresponding to the temperature value according to the temperature value of the environment where the RF module is located, and work according to the determined working parameter, so that the transmitting power or the receiving power of the RF module is the target value.

Taking the index of "transmission frequency" as an example, the calibration data includes "operating voltage and operating current of the power amplifier at different frequencies" and "standing wave value of the filter at different frequencies". The first calibration device calculates the working voltage and working current of the power amplifier under different frequencies and the standing wave value of the filter under different frequencies to obtain the working parameters of the RF module under the index of the emission frequency, namely the working parameters of the RF module under different frequencies. Therefore, the RF module can determine the working parameter corresponding to the frequency according to the current transmitting frequency and work according to the determined working parameter, so that the transmitting signal quality of the RF module meets the preset condition. The term "the quality of the transmission signal of the RF module satisfies the predetermined condition" means that the amplitude, the frequency and the initial phase of the transmission signal of the RF module all satisfy the predetermined condition.

The specific implementation manner of S203 is various, and may be, for example and without limitation, the following two examples:

according to an example I, the first calibration equipment calculates calibration data of a target device according to a preset calculation rule to obtain a calibration result of the RF module. Here, in the case of calibration data relating to at least two target devices, the "calculation rule" may mean: and configuring corresponding coefficients for the calibration data of different target devices, and obtaining the calibration result of the RF module based on the calibration data of different target devices and the coefficients corresponding to the calibration data. Therefore, the first calibration equipment does not need to perform centralized calibration on the RF module, and the calibration efficiency is improved.

And secondly, calibrating the RF module by the first calibration equipment according to the calibration data of the target device and the position information of the target device to obtain the calibration result of the RF module.

Wherein the location information of the target device is used to indicate the location of the target device in the RF module. For example, the location information of the target device may be coordinates of the target device in the RF module. For another example, in a case where the positions of the different devices in the RF module uniquely correspond to a number, the position information of the target device may be a number indicating the position of the target device in the RF module. Here, the first calibration apparatus collects image information of the RF module through its own imaging unit (such as an optical lens, a scanner, or a machine vision mechanism), and determines the position of the target device in the RF module in combination with the preconfigured information of the RF module. Wherein the preconfigured information may be predefined different device locations in the RF module. The processing procedure of "the first calibration device determines the position information of the target device" may be executed before S201, may be executed after S201, or may be executed simultaneously with S201, which is not limited in this embodiment of the application.

In practical applications, when the RF module is in an operating state, the following conditions may exist: only some of the plurality of devices of the RF module are in operation, and not all of the devices of the RF module are in operation. Further, the positional relationship formed between the target devices is different, and the calculation rule adopted when calculating the calibration data of the target devices is also different. The first calibration apparatus determines a calculation rule to be employed in calculating a calibration result of the RF module, based on the position information of the target device. For example, the first calibration device selects a corresponding calculation formula according to the positional relationship of the target device, and calculates the calibration data of the target device to obtain the calibration result of the RF module. Wherein, the position relation of the target device is based on the circuit design of the actual RF module.

Here, if the above calculation formula is a formula for calculating a calibration result of a certain index, the calculated calibration result of the RF module may be a calibration result of the index (e.g., temperature, transmission frequency, reception frequency, etc.).

If the target device with the position information is used to implement a first function of the RF module (e.g., a radio signal transmitting function, a radio signal receiving function, etc.), the calculated calibration result of the RF module may also be a calibration result characterizing the first function. For example, after the first calibration apparatus determines the position information of the plurality of target devices, the first calibration apparatus determines that the functions implemented by the plurality of target devices are "radio signal transmission functions" to constitute the transmission circuit, and performs calculation in combination with the calibration data of the plurality of target devices to obtain the calibration result of the transmission circuit.

In some embodiments, the first calibration device is further capable of storing the calibration results of different indices of the RF module in sections. Here, there are mainly two possible implementation approaches:

a first possible implementation is as follows: the RF module prestores different first indication information. Here, a piece of first indication information is used to indicate a storage area of the calibration result of an index in the RF module. The different first indication information indicates a storage area in the RF module of the calibration result of the different index. The first calibration device transmits a calibration result of the first index to the RF module. Accordingly, the RF module receives the calibration result of the first index from the first calibration device. The RF module inquires pre-stored first indication information, determines a storage area of the calibration result of the first index as a storage area 1, and stores the calibration result of the first index in the storage area 1.

Referring to fig. 4, a second possible implementation is as follows: the first calibration device indicates a memory area for calibration results of a first index for the RF module, so that the first calibration device stores the calibration results of different indices of the RF module in sections. I.e., the first calibration device performs S203, and then also performs S204 and S205. Wherein, the specific description of S204 and S205 is as follows:

S204, the first calibration equipment acquires first indication information related to the position information of the target device.

Wherein the first indication information is used for indicating a storage area 1 of the calibration result of the first index in the RF module.

Here, there are various specific implementations of S204, which may be, for example, but not limited to, the following two ways:

in the first mode, the first calibration device prestores the correspondence between the position information of the target device and the first indication information, and the first calibration device queries the prestored correspondence between the position information of the target device and the first indication information, that is, can obtain the first indication information corresponding to the position information of the target device.

Here, the "correspondence between the position information of the target device and the first indication information" may be carried in the joint mapping table. In the joint mapping table, the location information of the target device is specifically "location number of the target device in the RF module", and the first indication information is specifically "number of the storage area". The union mapping table may be as shown in table 1 below.

TABLE 1

Location numbering of target devices in RF modules	Numbering of storage areas
		A	1
B	2
		C	2
……	……

Referring to table 1, the letters are the position numbers of the target devices in the RF module, and are used to identify the different positions of the target devices in the RF module. The number is the number of the storage area. The memory areas identified by the numbers are all memory areas in the RF module. In the RF module, different memory areas store calibration results for different indices. For example, memory area 1 is used to store temperature compensation calibration results and may also be described as a "temperature compensation memory area". Memory area 2 is used to store transmit frequency compensation calibration results and may also be described as a "transmit frequency compensation memory area". The memory area 3 is used to store the reception frequency compensation calibration result, and may also be described as a "reception frequency compensation memory area". The memory area 4 is used to store the feedback channel compensation calibration result and can also be described as "feedback channel compensation memory area".

For example, in the case where the first calibration device calibrates the transmission frequency of a certain circuit in the RF module, the circuit includes the device 1 and the device 2. Wherein the position of the device 1 in the RF module is numbered B. The position of the device 2 in the RF module is numbered C. As can be seen from table 1, the location number B and the location number C both correspond to the storage area 2. After the first calibration apparatus obtains the transmission frequency compensation calibration result of the circuit based on the calibration data of the device 1 and the calibration data of the device 2, the first calibration apparatus stores the transmission frequency compensation calibration result of the circuit to the storage area 2.

In a second way, the first calibration device obtains the first indication information from the server, referring to fig. 5, that is, the specific implementation process of S204 is as follows:

s2041, the first calibration equipment sends the position information of the target device to the server. Accordingly, the server receives position information of the target device from the first calibration apparatus.

Wherein the location information of the target device is used to indicate the location of the target device in the RF module. The target device having the above-described position information is used to realize the first function. The server stores the corresponding relation between the position information of the target device and the first indication information. For a description of the correspondence between the position information of the target device and the first indication information, reference may be made to the description in the first embodiment, and details are not described here.

S2042, the server determines first indication information corresponding to the position information of the target device.

Here, the server prestores "the correspondence between the location information of the target device and the first indication information", and the server queries the prestored information, that is, may acquire the first indication information having a correspondence with the location information of the target device.

S2043, the server sends first indication information to the first calibration device. Accordingly, the first calibration device receives the first indication information from the server.

That is, the "correspondence between the position information of the target device and the first indication information" is stored in the server, and the first calibration apparatus can timely acquire the first indication information corresponding to the position information of the target device from the server to determine the storage area of the calibration result of the first index in the RF module, so as to implement the partition storage of the calibration results of different indices.

S205, the first calibration equipment sends the calibration result of the first index and the first indication information to the RF module. Accordingly, the RF module receives the calibration result of the first index and the first indication information from the first calibration device.

S206, the RF module stores the calibration result of the first index to the storage area 1 indicated by the first indication information.

The RF module includes a plurality of storage areas, and different storage areas are used to store calibration results of different indicators, and for a specific example, reference may be made to the relevant description of "storage area" in table 1, which is not described herein again.

It should be noted that, in the case where the server prestores "the correspondence between the identification information of the target device and the calibration data of the target device", the server acquires "the correspondence between the identification information of the target device and the calibration data of the target device" in advance. Referring to fig. 6, the specific implementation process is as follows:

and S207, calibrating the target device by the second calibration equipment to obtain calibration data of the target device.

Wherein the calibration data of the target device is used to compensate for the operational performance of the target device. For the related description of the calibration data, reference may be made to the related description in S202, which is not described herein again.

Here, in the case where the target device is a chip-type device, the second calibration apparatus calibrates not only different channels within the same chip in the target device but also channels between different chips in the target device to obtain calibration data of the target device. In the case where the target device is a non-chip type device, the second calibration apparatus calibrates a channel for signal transmission or reception in the target device to obtain calibration data of the target device.

S208, the second calibration equipment acquires the identification information of the target device.

For specific implementation processes of the "identification information" and the "identification information of the target device acquired by the second calibration device", reference may be made to the relevant description of S201, which is not described herein again.

It should be noted that the second calibration device may first execute S207 and then execute S208, may also first execute S208 and then execute S207, and may also execute S207 and S208 at the same time, which is not limited in this embodiment of the present application.

S209, the second calibration equipment sends the calibration data of the target device and the identification information of the target device to the server. Accordingly, the server receives calibration data of the target device and identification information of the target device from the second calibration apparatus.

The calibration data of the target device and the identification information of the target device are stored in the server and used for the first calibration equipment to generate the calibration result of the RF module. The RF module includes the target device, and the calibration result of the RF module is used to indicate the operating parameter of the RF module, which may specifically refer to the related description of S203 and is not described herein again.

S210, the server stores the corresponding relation between the calibration data of the target device and the identification information of the target device.

For example, the server may still store the correspondence between the identification information of the target device and the calibration data of the target device in the form of a table.

In this way, the server can acquire the calibration data of the target device and the identification information of the target device from the second calibration device to provide reference information for generating the calibration result of the RF module, thereby avoiding performing centralized calibration on a plurality of devices in the RF module.

The above description is made of "calibration data" and "calibration process of the RF module" by way of example. In the case that the "first data includes the aging data", the embodiment of the present application can further obtain the operating parameters of the RF module in the corresponding aging states based on the operating parameters of the target device in the different aging states. Referring to fig. 7, a specific implementation process of the embodiment of the present application is as follows:

s301, the first calibration equipment acquires identification information of a target device in the RF module.

For a specific implementation process of S301, reference may be made to the relevant description of S201, which is not described herein again.

S302, the first calibration equipment acquires first data according to the identification information of the target device.

Wherein the first data includes operating parameters of the target device in an aging state. Here, the aging state may refer to an operation state that the target device exhibits under the influence of an external factor.

For example, the output power of the power amplifier in a predetermined time period (e.g., a time period between 2 hours and 12 hours) under a certain humidity environment can be used as the operating parameter of the power amplifier in the predetermined humidity environment.

For another example, for a memory chip, the number of times that the memory chip can successfully erase and write data in a preset temperature environment can be used as an operating parameter of the memory chip in the preset temperature environment. Or, in the preset temperature environment, the number of times of occurrence of an abnormality in the process of erasing and writing data in the memory chip may also be used as a working parameter of the memory chip in the preset temperature environment.

And S303, the first calibration equipment obtains the working parameters of the RF module in the aging state according to the working parameters of the target device in the aging state.

For example, in order to obtain the output power when the usage duration of the RF module is a preset duration (e.g., 2 hours), the first calibration device may first obtain operating parameters, such as output voltage, output current, and the like, of the target device when the usage duration is the preset duration, and then calculate according to the operating parameters of the current device in the preset duration to obtain the output power when the usage duration of the RF module is the preset duration, so as to monitor the operating condition of the RF module in the aging state.

Here, in the process of "calculating the operating parameter of the RF module in the aging state", the first calibration device may also calculate the operating parameter of the target device in the aging state by using a preset calculation rule, so as to obtain the operating parameter of the RF module in the aging state. Or the first calibration device determines a calculation rule adopted for calculating the working parameter of the RF module in the aging state according to the position information of the target device, and calculates the working parameter of the target device in the aging state to obtain the working parameter of the RF module in the aging state.

In some embodiments, the first calibration device is further capable of storing "operating parameters of the RF module in an aged state" to the RF corresponding storage area. Here, there are also two possible implementation approaches:

a first possible implementation is as follows: the second indication information prestored in the RF module indicates a storage area in the RF module of "operating parameters of the RF module in an aged state". Here, the first calibration device transmits "the operating parameters of the RF module in an aged state" to the RF module. Accordingly, the RF module receives "operating parameters of the RF module in an aged state" from the first calibration device. The RF module refers to the pre-stored second indication information, determines that the storage area in the RF module of the "operating parameter of the RF module in an aged state" is the storage area 2, and stores the "operating parameter of the RF module in an aged state" in the storage area 2.

A second possible implementation is as follows: the first calibration device indicates a memory area for the RF module for "operating parameters of the RF module in an aged state". Referring to fig. 7, after the first calibration apparatus performs S303, S304 and S305 are also performed. Wherein, the specific descriptions of S304 and S305 are as follows:

s304, the first calibration equipment acquires second indication information related to the position information of the target device.

Wherein the second indication information is used to indicate the storage area 2 in the RF module of the "operating parameter of the RF module in the aged state".

Here, the first calibration apparatus may pre-store "a correspondence between the position information of the target device and the second indication information", and the first calibration apparatus may query the pre-stored "a correspondence between the position information of the target device and the second indication information", that is, may acquire the second indication information corresponding to the position information of the target device.

The first calibration device may also obtain the second indication information from the server. Referring to fig. 8, a specific implementation process of S304 may include the following processes:

s3041, the first calibration device sends the location information of the target device to the server. Accordingly, the server receives position information of the target device from the first calibration apparatus.

Wherein the location information of the target device is used to indicate the location of the target device in the RF module. The server stores the corresponding relation between the position information of the target device and the second indication information.

S3042, the server determines second indication information having a corresponding relationship with the position information of the target device.

Here, the server prestores the "corresponding relationship between the position information of the target device and the second indication information", and the server queries the prestored "corresponding relationship between the position information of the target device and the second indication information", that is, may acquire the second indication information in which the position information of the target device has a corresponding relationship. The second indication information is used to indicate the storage area 2 in the RF module of the "operating parameter of the RF module in an aged state".

S3043, the server sends the second indication information to the first calibration device. Accordingly, the first calibration device receives the second indication information from the server.

That is, the "correspondence between the position information of the target device and the second indication information" is stored in the server, and the first calibration apparatus can acquire the second indication information corresponding to the position information of the target device from the server in time.

S305, the first calibration equipment sends the working parameters and the second indication information of the RF module in the aging state to the RF module. Accordingly, the RF module receives the operating parameters and the second indication information of the RF module in the aged state from the first calibration device.

S306, the RF module stores the working parameters of the RF module in the aging state to the storage area 2 indicated by the second indication information.

Therefore, the RF module can store the working parameters of the RF module in the aging state into the corresponding storage area of the RF module. In the actual working process of the RF module, the actual working state of the RF module can be monitored by taking the working parameters of the RF module in an aging state as a reference, and the centralized test on different devices in the RF module is not needed, so that the complexity of a test link is greatly reduced.

It should be noted that, in the case where the server prestores "the correspondence between the identification information of the target device and the operating parameters of the target device in the aged state", the server prestores "the correspondence between the identification information of the target device and the operating parameters of the target device in the aged state". Referring to fig. 9, the specific implementation process is as follows:

and S307, testing the target device by the second calibration equipment to obtain working parameters of the target device in an aging state.

For the "operating parameters of the target device in the aging state" and the obtaining process, reference may be made to the relevant description of S302, which is not described herein again.

S308, the second calibration equipment acquires the identification information of the target device.

For a specific implementation process of S308, reference may be made to the related description of S208, which is not described herein again.

It should be noted that the second calibration device may first execute S307 and then execute S308, may also first execute S308 and then execute S307, and may also execute S307 and S308 at the same time, which is not limited in this embodiment of the present application.

S309, the second calibration equipment sends the working parameters of the target device in the aging state and the identification information of the target device to the server. Accordingly, the server receives the operating parameters of the target device in the aged state and the identification information of the target device from the second calibration apparatus.

S310, the server stores the corresponding relation between the working parameters of the target device in the aging state and the identification information of the target device.

For example, the server may still store the corresponding relationship between the operating parameters of the target device in the aging state and the identification information of the target device in the form of a table. Therefore, the server can acquire the working parameters of the target device in the aging state and the identification information of the target device from the second calibration device, so that the first calibration device can acquire the working parameters of the target device in the aging state in time.

In the case where the server performs S210, the server can also store the correspondence between the identification information of the target device and the first data.

It should be noted that, in the embodiment of the present application, the relevant processing procedure regarding "calibration data" and the processing procedure regarding "operating parameter in aging state" may be performed simultaneously. For example, the first calibration device may perform S203 and S303 simultaneously, and the second calibration device may perform S207 and S307 simultaneously. The server may perform S210 and S310 simultaneously. The embodiments of the present application do not limit this. The server in the embodiment of the present application may also be replaced with a portable storage device or a removable storage device.
