Detailed Description
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, the same calibration parameter is generally adopted for calibrating batch radio frequency products, and radio frequency products generally have certain difference, so that the consistency of the performance of the calibrated radio frequency products is poor, and the performance of each radio frequency product cannot be guaranteed to be optimal. A first embodiment of the present invention provides a radio frequency calibration method, which can distinguish different calibration items to adaptively perform radio frequency calibration, for example, fig. 1 is a basic flowchart of the radio frequency calibration method provided in this embodiment, and the radio frequency calibration method includes the following steps:
in this embodiment, the device to be calibrated may be an independent rf module, or may be a complete device installed with an rf module, such as a mobile phone, as an optional implementation manner of this embodiment, in this embodiment, WiFi calibration is performed, so that the WiFi calibration parameter is determined correspondingly.
Optionally, in this embodiment, the manners of determining the radio frequency calibration parameter of the current device to be calibrated include, but are not limited to, the following two manners:
the method comprises the steps that firstly, based on calibration item information of equipment to be calibrated, whether calibrated equipment which is the same as the calibration item information of the equipment to be calibrated exists is searched; when a calibrated device which has the same calibration item information as the device to be calibrated exists, determining the radio frequency calibration parameters of the calibrated device as the radio frequency calibration parameters of the device to be calibrated.
Specifically, in an embodiment, whether other devices to be calibrated having the same calibration item information are calibrated before is determined according to the calibration item information of the current device to be calibrated, if so, the radio frequency calibration parameters of the other previous devices to be calibrated have certain credibility with respect to the current device to be calibrated due to the same calibration item information, the radio frequency calibration parameters of the calibrated devices can be used as references of the current device to be calibrated, and it is not necessary to separately detect the current device to be calibrated to obtain corresponding radio frequency calibration parameters, so that the radio frequency calibration parameters are obtained with high efficiency.
Acquiring actual radio frequency parameters of the equipment to be calibrated through a test instrument in communication connection with the equipment to be calibrated; and determining radio frequency calibration parameters of the equipment to be calibrated according to the actual radio frequency parameters and preset standard radio frequency parameters.
Specifically, in another embodiment, in the case of other devices to be calibrated without previous calibration item information being the same, or in order to ensure calibration accuracy, the actual rf parameters of the current device to be calibrated are measured by a dedicated meter, and the standard rf parameters may be determined by a technician according to experience and actual application scenarios. It should be noted that, in this embodiment, a specific implementation manner of determining the radio frequency calibration parameter based on the actual radio frequency parameter and the standard radio frequency parameter may be to subtract the actual radio frequency parameter and the standard radio frequency parameter, and a difference value between the actual radio frequency parameter and the standard radio frequency parameter is the radio frequency calibration parameter.
In addition, in general, the larger the base number is, the stronger the regularity is, and the more accurate the represented result is, and based on this, in this embodiment, further, after obtaining the radio frequency calibration parameter through the instrument measurement for a certain number of devices to be calibrated having the same calibration item information, if the number of the devices to be calibrated that have been measured reaches the preset number threshold, based on the multiple radio frequency calibration parameters obtained through measurement, an accurate radio frequency calibration parameter is determined, and then the determined radio frequency calibration parameter is used as the reference value of the subsequent devices to be calibrated having the same calibration item information and is correspondingly stored.
102, acquiring calibration item information of equipment to be calibrated, and determining a calibration parameter effective address corresponding to the calibration item information according to the calibration item information;
in practical applications, the calibration item information of different devices to be calibrated is not absolutely the same, and in this embodiment, the calibration item information is used to distinguish the different devices to be calibrated, where the calibration item information may include a plurality of kinds of information, for example, at least one of device model information, production lot information, device name information, and device parameter information. In this case, the types of the calibration item information need to be determined based on a specific application scenario in practical application, and the type of the calibration item information is not limited herein. It should be further noted that since the periist partition has the read-write right, the radio frequency calibration parameters need to be directly written into the periist partition in the form of an xml file and converted into a bin file after being written, and since the radio frequency calibration parameters of different calibration items are different, different radio frequency calibration parameters need to be written into corresponding addresses to take effect, where the implementation in pttsocket.c may be as follows: project A- -write/persistence/A.bin, project B- -write/persistence/B.bin, and project C- -write/persistence/C.bin.
And 103, writing the radio frequency calibration parameters into the calibration parameter effective address, and controlling the radio frequency calibration parameters to take effect.
In the step 103, the rf calibration parameter is not directly valid after being written into the corresponding valid address, and in the related art, a general technical means is to restart the whole device equipped with the rf module, which may cause a significant reduction in working efficiency and a slow validation process of the calibration parameter. In an optional implementation manner of this embodiment, when the device to be calibrated is a complete machine device including a radio frequency module, only the radio frequency module is controlled to Restart, and then the radio frequency calibration parameter is used to update the radio frequency parameter of the radio frequency module, so that the radio frequency calibration parameter becomes valid, that is, a Subsystem Restart (SSR) function is added to an init.
Optionally, in this embodiment, the controlling the radio frequency module to restart, and then updating the radio frequency parameter of the radio frequency module by using the radio frequency calibration parameter includes, but is not limited to, the following two types:
in the first mode, the radio frequency module is controlled to be restarted, the drive of the radio frequency module is unloaded, and then the radio frequency parameters of the radio frequency module are updated by adopting the radio frequency calibration parameters.
And in the second mode, the drive of the radio frequency module is unloaded, then the radio frequency module is controlled to restart, and the radio frequency parameters of the radio frequency module are updated by adopting the radio frequency calibration parameters.
Specifically, in one case, the radio frequency module unloads the driver after the SSR, and then reloads the calibration parameters, and in another case, the driver is unloaded after the push of the XML file is completed, so that the WIFI is SSR in a normal mode. It should be noted that, in practical applications, if the complete equipment is in a Factory Test Mode (FTM), the SSR does not operate in a normal state of the radio frequency module, which may cause an abnormality, and as a result, the SSR time is too long, and if the drive is unloaded first at the FTM and then the SSR is performed, the SSR time is greatly shortened, based on which, in an implementation manner of this embodiment, after the radio frequency calibration parameter is written into the calibration parameter validation address, it is determined whether the complete equipment is currently in the Factory Test Mode FTM; if the whole equipment is in the FTM application scene, the radio frequency parameter updating is carried out by adopting the second mode so as to improve the flow execution speed.
And step 104, when the emission power of the equipment to be calibrated after the radio frequency calibration parameters are validated is detected, determining that the equipment to be calibrated passes the production line calibration comprehensive test.
Specifically, after the radio frequency calibration parameters are written into the radio frequency module and the radio frequency calibration parameters take effect, TX and RX index tests need to be performed on the radio frequency module adopting the radio frequency calibration parameters, and only after all indexes are tested to be qualified, the device to be calibrated is determined to be a qualified product. It should be understood that the emission indicators herein include at least: center frequency error, transmit spectrum mask, the receive index including at least the receive sensitivity.
Optionally, a specific implementation manner of detecting the transmission power of the device to be calibrated after the radio frequency calibration parameter takes effect may be to determine the actual transmission power of the device to be calibrated after the radio frequency calibration parameter takes effect; and comparing the actual transmitting power with a preset transmitting power threshold value, and detecting the transmitting power of the equipment to be calibrated. Namely, the actual transmitting power of the equipment to be calibrated is compared with the expected target transmitting power, whether the deviation between the actual transmitting power and the expected target transmitting power exceeds a preset amount or not is determined according to the comparison result, and if the deviation is within the preset amount, comprehensive measurement is carried out through production line calibration.
It should be further noted that, in this embodiment, in a scenario where a deviation between the actual transmit power and the preset transmit power threshold exceeds a preset amount, parameter compensation may also be performed on the radio frequency parameter of the device to be calibrated, so that the actual transmit power and the preset transmit power threshold are within a preset amount range, and comprehensive measurement is performed through production line calibration.
Based on the technical scheme of the embodiment of the application, the calibration item information is used for determining the calibration parameter effective address corresponding to the calibration item information, and the radio frequency calibration parameters corresponding to the calibration item information are controlled to take effect, that is, the radio frequency calibration is performed adaptively according to different calibration items, for example, different calibration items adopt different radio frequency calibration parameters to perform the radio frequency calibration, so that the consistency of the performance of different radio frequency products after calibration is improved, the comprehensive test passing rate of the radio frequency products is ensured, and the performance of the radio frequency products is optimized.
The method in fig. 2 is a refined rf calibration method according to a second embodiment of the present invention, where the method includes:
In this embodiment, the calibration item information may include a plurality of information, for example, at least one of device model information, production lot information, device name information, and device parameter information
in an embodiment, the radio frequency calibration parameter of the calibrated device is used as a reference of the current device to be calibrated, and the corresponding radio frequency calibration parameter is acquired without separately detecting the current device to be calibrated, so that the acquisition efficiency of the radio frequency calibration parameter is high.
in another embodiment, for example, in the case that there is no other device to be calibrated with the same previous calibration item information, a dedicated instrument is used to measure the actual WiFi parameter of the current device to be calibrated, and then the difference value obtained by subtracting the preset standard WiFi parameter from the actual WiFi parameter is the WiFi calibration parameter.
specifically, the periist partition has a read-write permission, the radio frequency calibration parameters need to be directly written into the periist partition in an xml file form, and are converted into a bin file after being written, and different radio frequency calibration parameters need to be written into corresponding addresses to take effect due to different radio frequency calibration parameters of different calibration items.
And step 205, unloading the drive of the WiFi module, then controlling the WiFi module to restart, and updating the WiFi parameters of the WiFi module by adopting the WiFi calibration parameters.
In this embodiment, only the WiFi module is controlled to restart, and then the WiFi parameter of the WiFi module is updated by using the WiFi calibration parameter, so that the WiFi calibration parameter takes effect. In addition, in practical application, the application scenario that the terminal to be calibrated may be in a factory test mode is considered, the SSR does not operate in a normal state of the radio frequency module, and an abnormality is caused, and as a result, the SSR time is too long.
And step 206, determining the actual emission power of the terminal to be calibrated after the WiFi calibration parameters take effect, and determining that the terminal to be calibrated passes production line calibration comprehensive test when the actual emission power is within a preset emission power threshold value.
In this embodiment, the actual transmitting power after the calibration of the terminal to be calibrated is compared with the expected target transmitting power, and then whether the deviation between the actual transmitting power and the expected target transmitting power exceeds a preset amount is determined according to the comparison result, and if the deviation is within the preset amount, the comprehensive measurement is performed through the production line calibration. It should be noted that, in a scenario where the deviation between the actual transmit power and the preset transmit power threshold exceeds the preset amount, parameter compensation may be performed on the WiFi parameter of the terminal to be calibrated, so that the actual transmit power and the preset transmit power threshold are within the preset amount range, and comprehensive measurement is performed through production line calibration.
The embodiment of the application discloses a radio frequency calibration method, for each terminal to be calibrated provided with a WiFi module, WiFi calibration parameters of the terminal to be calibrated are determined based on WiFi calibration parameters of calibrated equipment or a test instrument, the WiFi calibration parameters are written into calibration parameter effective addresses corresponding to calibration item information of the terminal to be calibrated, then SSR is carried out in a normal mode after the drive of the WiFi module is unloaded, the WiFi calibration parameters are enabled to be effective, and finally when the terminal to be calibrated after the WiFi calibration parameters are enabled to be effective is subjected to emission power detection, the terminal to be calibrated is determined to be subjected to comprehensive production line calibration and test. The WiFi calibration is carried out adaptively by distinguishing different calibration items, so that the consistency of the performance of the WiFi product is improved, the comprehensive test passing rate of the WiFi product is ensured, and the performance of the WiFi product is optimized.
