[0028] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.
[0029] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0030] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] At present, WIFI modules need to undergo RF testing during the production process, and the test results can be used to analyze whether the WIFI modules meet the standards. Since the test instruments and wires of the WIFI modules have line losses, the line losses need to be calibrated and compensated in the line loss settings. However, the current test methods cannot directly measure the line losses of the test instruments, which results in a large error in the final line loss meter of the WIFI module.
[0032] In view of the above problems, the embodiments of the present application provide a method, system, electronic device and storage medium for calibrating a WIFI module test instrument, which can accurately measure the line loss of the test instrument, thereby improving the line loss measurement accuracy of the WIFI module.
[0033] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0034] Figure 1 It is a flow chart of a method for calibrating a WIFI module test instrument shown in an embodiment of the present application.
[0035] See also Figure 1 , a method for calibrating a WIFI module test instrument, comprising:
[0036] Step S101: Control a first WIFI module standard component to transmit a plurality of first radio frequency data, and a test instrument obtains a plurality of first current power values according to the first radio frequency data.
[0037] It should be noted that the first WIFI module standard part is a standard WIFI module that has been tested for line loss, that is, all its data are standard data. Furthermore, in order to avoid test result errors caused by unstable signals, the intelligent terminal will call the corresponding test program to control the first WIFI module standard part to transmit multiple first radio frequency data according to the model of the first WIFI module. The multiple first radio frequency data here refer to the radio frequency signal of the first WIFI module in the specified mode and channel, such as 5G signal or 2.4G signal. Each mode and channel will transmit 5, so that the test instrument will obtain 5 corresponding first current power values.
[0038] Step S102: The testing instrument calculates and processes each first current power value, outputs a first real-time power value, calculates and processes the first real-time power value and the preset power value, and outputs a first current signal line loss value.
[0039] It should be noted that the test instrument will remove the maximum and minimum values of the five first current power values, and take the average of the three middle power values as the first real-time power value. Then the difference between the first real-time power value and the preset power value is taken as the first current signal line loss value. The preset power value is the standard power value of the test instrument.
[0040] Step S103: upload the first current signal line loss value, output the line loss file and file expiration data, bind the file expiration data with the line loss file, and generate a line loss test file.
[0041] It should be noted that the intelligent terminal will upload and save the first current signal line loss value, and then bind the line loss file to the validity period to remind the test instrument that the line loss value needs to be updated on time, thereby improving the accuracy of line loss measurement.
[0042] Figure 2 FIG. 4 is a flow chart of a method for calibrating a WIFI module testing instrument according to another embodiment of the present application.
[0043] Step S201: Control the second WIFI module standard component to transmit a plurality of second radio frequency data, and the test instrument obtains a plurality of second current power values according to the second radio frequency data.
[0044] Step S202: The testing instrument calculates and processes each second current power value, outputs a second real-time power value, calculates and processes the second real-time power value and the preset power value, and outputs a second current signal line loss value.
[0045] It should be noted that, in order to reduce the error caused by the instability of individual WIFI module standard parts, the smart terminal will control the second WIFI module standard part to repeat the calibration test, wherein the second WIFI module standard part may include multiple WIFI module standard parts.
[0046] Step S203: Calculate and process the second current signal line loss value and the first current signal line loss value, output a processed power value, and use the processed power value as the current signal line loss value.
[0047] It should be noted that in order to improve the accuracy of the test, the second current signal line loss value and the first current signal line loss value output under the same mode and signal are averaged to obtain a processed power value, and finally the processed power value is used as the current signal line loss value.
[0048] Step S204, determine whether the current signal line loss value is greater than the preset configuration threshold, if not, upload the current signal line loss value for processing, output the line loss file and file expiration data, bind the file expiration data with the line loss file, and generate a line loss test file.
[0049] It should be noted that this application puts the same model of WIFI module standard parts into the loop test. After the loop test is completed, it is determined whether the current signal line loss value exceeds the preset threshold of the configuration item. If so, the system will re-inspect and calibrate the workstation.
[0050] Further, in another embodiment, see Figure 3 , a method for calibrating a WIFI module test instrument, further comprising:
[0051] Step S301, receiving the input product model data, and searching for the available line loss file according to the product model data.
[0052] Step S302: determine whether the deadline for using the line loss file exceeds the preset deadline; if not, output the usable line loss file as a line loss test file.
[0053] It should be noted that before the test instrument tests the line loss, the intelligent terminal will receive the manually entered product model data and search for the available line loss file based on the product model data. The test will only be performed if the available line loss file has expired. This can save test time and improve test efficiency.
[0054] Further, in another embodiment, see Figure 4 , a method for calibrating a WIFI module test instrument, further comprising:
[0055] Step S401, running the line loss test file, outputting the first test data and the second test data;
[0056] Step S402, analyzing the first test data and outputting a defective product test document;
[0057] S403, analyzing the second test data and outputting a good product test document;
[0058] S404, writing the defective product test document and the good product test document to the server.
[0059] It should be noted that the first test data is the data that failed the test, and the second test data is the data that passed the test. The second test data includes information such as MAC address, station ID, test time, target value, range value, etc., and lists extreme values, calculation margins, average values, standard deviations, etc. through retrieval data. After analyzing these data, good product test documents are generated to facilitate subsequent production of standard data. After analyzing the first test data, defective product test documents will be output. The smart terminal will analyze the reasons why each data in the defective product test document failed, so as to focus on the reasons for the large proportion of subsequent tests.
