Description

Technical Field

[0001] This application relates to the field of wireless router product manufacturing and calibration, and in particular to a method, system, and computer storage medium for extracting CPK data based on WIFI testing. Background Technology

[0002] CPK, or Process Capability Index, refers to the degree to which a process's capability meets product quality standards (specification range, etc.). Also known as the operational capability index, it refers to the actual processing capacity of a process under controlled (stable) conditions over a given period. It represents the inherent capability of the process, or in other words, its ability to guarantee quality. The operational process referred to here encompasses the combined effects of five fundamental quality factors: operator, machine, raw materials, technological methods, and production environment—in other words, the production process of the product.

[0003] Wireless routers designed based on Wi-Fi products require calibration testing of a series of Wi-Fi parameters to ensure communication performance. Since manually extracting CPK test data from Wi-Fi products is time-consuming and labor-intensive, there is an urgent need for an automated method for CPK data extraction. Summary of the Invention

[0004] (a) Purpose of application Based on this, in order to efficiently extract CPK data from WIFI products, this application discloses the following technical solution.

[0005] (II) Technical Solution This application discloses a method for extracting CPK data based on WIFI testing, including: By scanning the product serial number with the product testing software and submitting it to the MES database, the product is bound to the product testing software. Perform WIFI calibration and save the calibrated parameters; Perform a WIFI test based on the calibrated parameters to verify whether the calibrated parameters are qualified; If the calibration parameters are qualified, extract the CPK data from the test LOG file and upload the CPK data to the MES database.

[0006] In one possible implementation, the method for binding the product with the product testing software specifically includes: Before product manufacturing, import identification information, including the product serial number, into the MES database system; After powering on the product and waiting for it to activate, use product testing software to scan the product serial number to bind the product to the serial number.

[0007] In one possible implementation, the WIFI calibration method specifically includes: By establishing a communication connection with the product, calibration instructions determined by the product's chip design are sent to the product. The product undergoes frequency offset calibration and power calibration according to the calibration instructions.

[0008] In one possible implementation, the frequency offset calibration and power calibration method specifically includes: Based on the initial frequency offset index value and initial power index value set in the calibration instruction, the product emits the corresponding target frequency offset value and the corresponding target power value. The calibration tool accepts the target frequency offset value and the target power value, and calculates the difference between the initial frequency offset index value and the target frequency offset value, and the difference between the initial power index value and the target power value, respectively. The calibration tool performs a difference compensation operation based on the initial frequency offset index value and the initial power index value, and writes the difference into the calibration command and issues it. After repeating this process several times, the calibration parameters are obtained, namely the final frequency offset index value corresponding to the target frequency offset value and the final power index value corresponding to the target power value.

[0009] In one possible implementation, the final frequency offset index value and the final power index value after calibration are written into the flash memory chip via a save command.

[0010] In one possible implementation, since the range of half the index values ​​of a WIFI chip has an empirical value that does not vary from product to product, the calibration range can be limited by configuring the upper and lower limits of the index values ​​before WIFI calibration.

[0011] In one possible implementation, the WIFI testing method is as follows: establish a communication connection with the product, send a power command to the product, and then obtain various indicators of the product through a WIFI testing instrument. Test whether each indicator is within the specified range according to the calibrated parameters. If each indicator is within the specified range, the calibrated parameters are qualified; otherwise, the calibrated parameters are unqualified.

[0012] In one possible implementation, the metrics primarily include transmit power (POWER), vector deviation (EVM), spectrum template (MASK), frequency offset (PPM), sensitivity, and packet loss rate for each channel across each bandwidth.

[0013] In one possible implementation, the CPK data is searched in the LOG file using keywords as indexes. If the WIFI calibration is performed using open-source calibration testing software, strings can be added to the software source code for concatenation to extract the CPK data. The integrated CPK data is then uploaded by calling the Webservice upload interface provided by the MES system.

[0014] As a second aspect of this application, this application also discloses a CPK data extraction system based on WIFI testing, including: The preparation module scans the product serial number using the product testing software and submits it to the MES database, thus binding the product to the product testing software. The calibration module performs WIFI calibration and saves the calibrated parameters. The testing module performs WIFI tests based on the calibrated parameters to verify whether the calibrated parameters are qualified. If the calibration parameters are qualified, the extraction module extracts the CPK data from the test LOG file and uploads the CPK data to the MES database.

[0015] As a third aspect of this application, this application also discloses a computer-readable storage medium having a computer program stored thereon, characterized in that the computer program, when executed, implements the CPK data extraction method based on WIFI testing as described in any of the preceding claims.

[0016] (III) Beneficial Effects The CPK data extraction method based on WIFI testing disclosed in this application can be applied to the production of large-scale WIFI products. By using the WIFI product calibration parameters for WIFI testing, it can effectively avoid the problem of WIFI test failure caused by using uniform calibration parameters and improve the extraction efficiency of CPK data.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings.

[0020] The following is for reference. Figure 1 This application provides a detailed description of embodiments of the CPK data extraction method based on WIFI testing disclosed in this application. (Refer to...) Figure 1 The CPK data extraction method based on WIFI testing disclosed in this embodiment mainly includes steps S10 to S40.

[0021] S10: Scan the product serial number using product testing software and submit it to the MES database to bind the product to the product testing software; Specifically, the methods for linking products with product testing software include: Before product manufacturing, import identification information, including the product serial number, into the MES database system; After powering on the product and waiting for it to activate, use the product testing software to scan the product serial number to bind the product to the testing software.

[0022] Among them, such as Figure 2 As shown, after the product is powered on, the product testing software will pop up a window representing the product. By scanning the product serial number with the product testing software, the product binding is completed, which facilitates the subsequent WIFI calibration process by querying the data of the corresponding product through the product serial number.

[0023] S20: Perform WIFI calibration and save the calibrated parameters; The specific methods for WIFI calibration include: By establishing a communication connection with the product, such as a telnet connection or a serial port connection, calibration commands determined by the product's chip design are sent to the product. The product undergoes frequency offset calibration and power calibration according to the calibration instructions.

[0024] Specifically, such as Figure 3 As shown, the methods for frequency offset calibration and power calibration specifically include: S21~S23.

[0025] S21: The product sends out the corresponding target frequency deviation value and the corresponding target power value according to the initial frequency deviation index value and initial power index value set in the calibration instruction; S22: The calibration tool accepts the target frequency offset value and the target power value, and calculates the difference between the initial frequency offset index value and the target frequency offset value, and the difference between the initial power index value and the target power value, respectively; S23: The calibration tool performs the difference compensation operation based on the initial frequency offset index value and the initial power index value and writes it in the calibration command. After repeating this several times, the calibration completed parameters are obtained, namely the final frequency offset index value corresponding to the target frequency offset value and the final power index value corresponding to the target power value.

[0026] The final frequency offset index value and final power index value after calibration are written into the flash memory chip via a save command.

[0027] Because the range of half the index value of a WIFI chip has an empirical value that does not change depending on the individual product, the calibration range can be limited by configuring the upper and lower limits of the index value before WIFI calibration.

[0028] S30: Perform a WIFI test based on the calibrated parameters to verify whether the calibrated parameters are qualified; Specifically, the WIFI testing method is as follows: establish a communication connection with the product through telnet or serial port, send a power command to the product, and then obtain various indicators of the product through a WIFI testing instrument. Test whether each indicator is within the specified range according to the calibrated parameters. If each indicator is within the specified range, the calibrated parameters are qualified; otherwise, the calibrated parameters are unqualified. The indicators mainly include the transmit power POWER, vector deviation EVM, spectrum template MASK, frequency offset PPM, sensitivity, and packet loss rate of each channel in each bandwidth.

[0029] S40: If the calibration parameters are qualified, extract the CPK data from the test LOG file and upload the CPK data to the MES database.

[0030] If the calibration parameters are not up to standard, the WIFI test will fail and no CPK data-related operations will be performed.

[0031] Specifically, if the WIFI test is successful, the CPK data can be found in the LOG file by keyword index. If the WIFI calibration is completed through open-source calibration testing software, strings can be added to the software source code for concatenation to extract the CPK data. The integrated CPK data can then be uploaded by calling the Webservice upload interface provided by the MES system. The CPK data can also be checked on other interfaces provided by the MES system to see if it has been uploaded successfully.

[0032] Based on the same inventive concept, referring to Figure 4This invention also provides a CPK data extraction system based on WIFI testing, comprising: The preparation module scans the product serial number using the product testing software and submits it to the MES database, thus binding the product to the product testing software. The calibration module performs WIFI calibration and saves the calibrated parameters. The testing module performs WIFI tests based on the calibrated parameters to verify whether the calibrated parameters are qualified. If the calibration parameters are qualified, the extraction module extracts the CPK data from the test LOG file and uploads the CPK data to the MES database.

[0033] Based on the same inventive concept, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon. In one embodiment, the computer-readable storage medium is a flash memory chip containing a C# program capable of processing and executing the CPK data extraction method based on WIFI testing as described above. The C# HTTP class simulates the process of manually submitting CPK data, ensuring the reliability of WIFI production.

[0034] The CPK data extraction method, system, and computer storage medium disclosed in this application based on WIFI testing can be applied to the production of large-scale WIFI products. By using the WIFI product calibration parameters for WIFI testing, the problem of WIFI test failure caused by using uniform calibration parameters can be effectively avoided, thereby improving the efficiency of CPK data extraction.
