[0002] In the field of wireless or radio frequency (RF) control technology, RF control systems, RF receiving systems and other RF systems are involved. Before these systems are put into production and factory, they need to be tested to ensure that the quality and performance of the RF systems meet the standards. In actual application, the existing test instruments are usually used to test the RF systems. However, since the test instrument and the UUT can only be connected by wire, the test instrument needs to be manually confirmed by the operator for the next step when testing the RF system, which makes the test process more troublesome and causes low test efficiency. Therefore, it is particularly important to develop an automatic test platform that can improve the test efficiency, and it is also particularly important to calibrate the test platform before using the test platform.

[0003] In the prior art, when calibrating the test platform, the research and development personnel or engineers need to manually calibrate each module of the test platform, which has low automation degree. Manual operation is not only inefficient, but also easily affected by human factors such as the skill level and operation habit of the operator, resulting in poor consistency of the calibration results. For example, manual reading of instrument measurement data and manual adjustment of test platform parameters may produce different calibration results due to the differences between different operators.

[0027] The test platform calibration method for RF systems provided in this invention is applied to the test platform calibration method apparatus for RF systems. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] In the field of RF control technology, RF systems, such as RF control systems and RF receiving systems, are involved. These systems need to be tested before leaving the factory to ensure that their quality and performance meet standards. In practical applications, RF systems are usually tested using existing test instruments. However, since the test instrument and the RF system can only be connected via wires, the operator needs to manually confirm the next step during testing, making the testing process cumbersome and resulting in low testing efficiency. Therefore, developing an automated test platform that can improve testing efficiency is particularly important, as is calibrating the test platform before use.

[0031] Current technology requires test platform calibration to be performed manually by R&D personnel or engineers, with each module requiring manual calibration, resulting in low automation. Manual operation is not only inefficient but also susceptible to human factors, such as the operator's skill level and operating habits, leading to inconsistent calibration results. For example, manually reading instrument measurement data and adjusting test platform parameters may produce different calibration results depending on the operator.

[0032] To achieve the above objectives, embodiments of the present invention provide a test platform calibration method for an RF system, applied to a test platform, such as... Figure 1 As shown, the method includes:

[0033] Step 101: Establish a wireless connection with the standard RF system and perform code pairing, and receive the test platform calibration command triggered by the user.

[0034] In this embodiment of the invention, the test platform can power the standard RF system. After the standard RF system is electrically connected to the test platform, the test platform can pair with the standard RF system. Alternatively, the standard RF system can be powered through other external circuits. When the standard RF system is powered on through an external circuit, the test platform can also pair with the standard RF system. After successful pairing, the standard RF system can enter factory mode or normal operating mode. The specific process of pairing the test platform with the standard RF system is as follows: When the test platform detects the access of the standard RF system, it sends a pairing request to the standard RF system. The pairing request includes the test platform's own identification (platform identity, authorization code, and a request for the standard RF system to return identity information (system serial number, model, supported communication protocol version)). After receiving the pairing request, the standard RF system verifies the test platform's platform identity and authorization code. If the verification fails, it refuses to respond. If the verification succeeds, it returns its own identity information, allowing the test platform to perform system identity verification and confirm whether the system serial number and model are compatible. The test task list includes a check to ensure the system supports compatible protocol versions with the test platform. If compatible, a "pairing successful" message will be sent. After successful pairing, the test platform and the standard RF system can establish a stable wireless communication link. The test platform can send a calibration notification to the standard RF system, enabling the standard RF system to process the target RF signal and generate actual parameter data upon receiving subsequent performance parameter calibration instructions, thus achieving "one-click" calibration of the test platform. If pairing times out or fails, "pairing timeout" or "pairing failed" messages will be displayed so that operators can promptly take further action.

[0035] The standard RF system can be any RF system whose performance indicators meet preset standards, specifically a standard RF system calibrated using existing testing instruments. In this invention, only one RF system calibration is required. After obtaining the standard RF system, the test platform can be automatically calibrated, allowing for the automatic testing or calibration of numerous RF systems under test. Compared to existing technologies, the test platform provided by this invention significantly simplifies both the testing and calibration processes.

[0036] Step 102: Read the initial values ​​of the target performance parameters, the preset parameter deviation range, and the preset signal power value from the test platform.

[0037] It should be noted that the test platform can be equipped with a "calibrate" button or key. Users can trigger the test platform calibration command by clicking or pressing the "calibrate" button or key. After receiving the calibration command, the test platform can begin calibration. To better facilitate test platform calibration, the test platform may include a host computer and a rack, such as...Figure 2 As shown, the cavity of the test fixture can be used to house the RF system, and the RF system communicates with the test fixture via a wireless communication link and performs code pairing. The host computer for testing is equipped with a "calibration" button or key, as well as a serial port for digital communication with the test fixture. When a calibration command is detected from the test platform, the calibration command can be sent to the test fixture through the digital communication serial port.

[0038] Furthermore, users can set the initial values ​​and preset deviation ranges of various performance parameters through the host computer or the settings interface, allowing the test platform to pre-store the initial values ​​and preset deviation ranges of different performance parameters locally. For RF systems, the relevant performance parameters may include frequency parameters, Received Signal Strength Indication (RSSI) parameters, power parameters, sensitivity parameters, voltage parameters, etc., which are not limited in this embodiment of the invention. The test platform can test the aforementioned performance parameters of the RF system.

[0039] In this embodiment of the invention, a performance parameter can be selected from multiple performance parameters included in the calibration instruction of the test platform according to a preset order rule to determine the target performance parameter; or a performance parameter can be selected from multiple performance parameters pre-saved locally on the test platform according to a preset order rule to determine the target performance parameter.

[0040] To support testing of different types of RF systems, the test platform pre-stores system type information and multiple performance parameters corresponding to different RF systems locally. The preset ordering rule can determine the order based on performance parameter priority, calibration time, or performance calibration dependencies. Therefore, when calibrating the test platform, multiple performance parameters of the RF system can be read from the test platform based on the system type information contained in the calibration instructions; and one performance parameter can be selected from these parameters according to the preset ordering rule to be the target performance parameter for the current calibration.

[0041] Step 103: Based on the initial parameter values ​​and / or preset signal power values, generate a target performance parameter calibration command and send it to the standard RF system. The standard RF system is used to process the target radio frequency signal and generate actual parameter values ​​for the target performance parameters according to the target performance parameter calibration command.

[0042] In this embodiment of the invention, after receiving a calibration command for the target performance parameters, the standard RF system can transmit or receive the target radio frequency signal according to the signal power setting value, and generate the actual value of the parameter for the target performance parameters.

[0043] For example, if the target performance parameter is a frequency parameter, a frequency parameter calibration command is generated and sent to the standard RF system. This command may include a preset signal power value, causing the RF system under test (DUT) to transmit or receive a target RF signal with the preset signal power value after receiving the calibration command, generating RSSI values ​​at different frequency points. The test platform can then record the RSSI values ​​of the DUT at these different frequency points, generate the actual frequency waveform, and calculate the frequency parameter deviation based on the actual waveform and the initial waveform.

[0044] Step 104: Obtain the parameter deviation value of the target performance parameter. The parameter deviation value of the target performance parameter is determined based on the actual value and the initial value of the target performance parameter.

[0045] Step 105: Based on the parameter deviation value and the preset parameter deviation range, calibrate the initial value of the parameter to obtain the standard value of the target performance parameter; and select the next performance parameter as the target performance parameter. Repeat the above steps until the standard value of each performance parameter is obtained.

[0046] In this embodiment of the invention, the step of calibrating the initial value of the parameter according to the parameter deviation value of the target performance parameter and the preset parameter deviation range to obtain the parameter standard value of the target performance parameter may specifically include: determining whether the parameter deviation value of the target performance parameter is within the preset parameter deviation range of the target performance parameter; if the parameter deviation value of the target performance parameter is not within the preset deviation range of the target performance parameter, calibrating the initial value of the target performance parameter based on the parameter deviation value of the target performance parameter; and repeatedly executing the steps of generating the target performance parameter calibration command and determining the parameter deviation value according to the parameter calibration value of the target performance parameter and / or the preset signal power value until the parameter deviation value of the target performance parameter is within the preset deviation range, thereby obtaining the parameter standard value of the target performance parameter.

[0047] It should be noted that the step of selecting the next performance parameter as the target performance parameter may specifically include: monitoring the calibration status of the target performance parameter; and, based on the calibration status, monitoring whether the calibration status of the target performance parameter is in a calibration completion state. If the calibration status is calibration completion, the next performance parameter can be directly selected as the target performance parameter; if the calibration status is calibration in progress, the calibration status can be waited for to be updated to calibration completion before selecting the next performance parameter as the target performance parameter; if the calibration status is calibration anomaly, a calibration anomaly prompt message can be triggered, allowing calibration personnel to rectify the calibration anomaly. After the calibration anomaly disappears, the current performance parameter is reselected as the target performance parameter, and the above steps are repeated until all performance parameters are calibrated. In this embodiment of the invention, by setting an anomaly detection mechanism, the calibration of the test platform can be further guaranteed to be completed.

[0048] This invention provides a test platform calibration method for an RF system. This method enables the establishment of a wireless connection and code pairing with a standard RF system. Upon receiving a user-triggered test platform calibration command, it can read the initial value, preset parameter deviation range, and preset signal power value of the target performance parameters from the test platform. Based on the initial and / or preset signal power values, it generates a target performance parameter calibration command and sends it to the standard RF system, allowing the standard RF system to process the target RF signal and generate actual values ​​for the target performance parameters. It also acquires the parameter deviation value of the target performance parameters, which is determined based on the actual and initial values. Based on the parameter deviation value and the preset parameter deviation range, it calibrates the initial values ​​to obtain the standard values ​​of the target performance parameters. Finally, it selects the next performance parameter as the target performance parameter and repeats the above steps until the standard values ​​of each performance parameter are obtained. In other words, compared with existing technologies, this invention enables the completion of various calibration stages of the test platform based on a standard RF system and a user's "one-click" trigger operation. Throughout the calibration process, the test platform automatically generates calibration instructions for the target performance parameters based on the initial values ​​of the target performance parameters and the preset signal power values. This allows the standard RF system to automatically process the target radio frequency signal, obtain the actual values ​​of the target performance parameters, and then the test platform to obtain the parameter deviation values. Based on the parameter deviation values ​​and the preset parameter deviation range, the initial parameter values ​​are calibrated to obtain the standard values ​​of the target performance parameters. Automatic calibration of any target performance parameter is possible, and each calibration step can be automatically switched during the calibration process without user intervention or manual confirmation. Furthermore, after the calibration of one target performance parameter is completed, the system can automatically switch to the next performance parameter calibration without user input or manual confirmation. Overall, this greatly simplifies the calibration process of the test platform, thereby improving its calibration efficiency and avoiding inconsistencies caused by manual user calibration.

[0049] To achieve the above objectives, embodiments of the present invention provide another test platform calibration method for RF systems, applied to a test platform, such as... Figure 3 As shown, the method includes:

[0050] Step 301: Establish a wireless connection with the standard RF system and perform code pairing; receive user-triggered test platform calibration commands.

[0051] It should be noted that step 301 has been described in detail in step 101, and the embodiments of the present invention are not limited here.

[0052] Step 302: Read the initial values ​​of the target performance parameters, the preset parameter deviation range, and the preset signal power value from the test platform.

[0053] In a specific embodiment of the present invention, before reading the initial value of the target performance parameter, the preset parameter deviation range, and the preset signal power value from the test platform locally, the method may further include: determining the target performance parameter for the current calibration. The step of determining the target performance parameter for the current calibration may specifically include: selecting a performance parameter as the target performance parameter from multiple performance parameters included in the test platform calibration instruction according to a preset order rule; or selecting a performance parameter as the target performance parameter from multiple performance parameters pre-saved locally on the test platform according to a preset order rule.

[0054] Step 303: Generate a target performance parameter calibration command based on the initial parameter value and / or preset signal power value and send it to the standard RF system; the standard RF system is used to process the target radio frequency signal and generate the actual parameter values ​​for the target performance parameters according to the target performance parameter calibration command.

[0055] Step 304: Obtain the parameter deviation values ​​of the target performance parameters.

[0056] In this embodiment of the invention, the step of obtaining the parameter deviation value of the target performance parameter based on the actual value and the initial value of the target performance parameter can specifically include: obtaining the parameter deviation value returned by the standard RF system, whereby the parameter deviation value is determined by the standard RF system based on its measured actual value and the initial value of the parameter; or, obtaining the actual value of the parameter returned by the standard RF system; determining the parameter deviation value based on the returned actual value and the initial value of the parameter; or, measuring the actual value of the parameter independently; determining the parameter deviation value based on the independently measured actual value and the initial value of the parameter. That is, in this embodiment of the invention, the test platform may obtain the parameter deviation value in different ways depending on the type of performance parameter. This embodiment of the invention provides three methods, and the specific method for obtaining the parameter deviation value is not limited here.

[0057] Step 305: Determine whether the parameter deviation value of the target performance parameter is within the preset parameter deviation range.

[0058] Step 306: If the parameter deviation value of the target performance parameter is not within the preset deviation range, then the initial value of the target performance parameter is calibrated based on the parameter deviation value of the target performance parameter.

[0059] In this embodiment of the invention, after calibrating the initial value of the target performance parameter, the steps of generating the target performance parameter calibration command and judging the parameter deviation value can be repeatedly executed based on the parameter calibration value of the target performance parameter and / or the preset signal power value. That is, the execution returns to step 303, generates the target performance parameter calibration based on the parameter calibration value (calibrated initial value of the parameter) and / or the preset signal power value, obtains the actual value of the standard RF parameter, calculates the new parameter deviation value based on the calibrated initial value of the parameter and the newly obtained actual value of the parameter, and compares the new parameter deviation value with the preset deviation range.

[0060] Step 307: If the parameter deviation value of the target performance parameter is within the preset deviation range, then the parameter calibration value corresponding to the parameter deviation value is determined as the parameter standard value of the target performance parameter.

[0061] To better illustrate the embodiments of the present invention, examples of testing several performance parameters are given below:

[0062] If the target performance parameter is a frequency parameter, the test platform will send a frequency parameter calibration command to the standard RF system, causing the standard RF system to send a target RF signal that meets the preset signal power value and generate RSSI values ​​at different frequency points. Under the constraints of "Advanced Frequency Test Settings", the test platform will obtain the measured frequency waveform by reading the RSSI values ​​at different frequency points of the standard RF system, as well as the initial frequency waveform saved in the test fixture beforehand. Based on the measured frequency waveform and the initial frequency waveform, the platform will determine the frequency deviation waveform and compare it with the preset frequency deviation range. If the frequency deviation value is not within the preset frequency deviation range, the platform will calibrate the initial frequency waveform based on the frequency deviation value. Based on the frequency calibration value and / or the preset signal power value, the steps of generating the frequency parameter calibration command and judging the parameter deviation value will be repeated until the frequency parameter deviation value is within the preset deviation range, thus obtaining the standard value of the frequency parameter (standard frequency waveform).

[0063] If the target performance parameter is an RSSI parameter, the test platform will send an RSSI parameter calibration command to the standard RF system, causing the standard RF system to send a target RF signal that meets the preset signal power value and generate an RSSI value. The standard RF system will record the actual RSSI parameter value (the average of multiple measured RSSI values ​​can be taken). Based on the actual RSSI parameter value and the initial RSSI parameter value, the RSSI parameter deviation value will be determined and fed back to the test platform. The test platform will compare the RSSI deviation value with the preset RSSI deviation range. If the RSSI deviation value is not within the preset RSSI deviation range, the initial RSSI value will be calibrated based on the RSSI deviation value. Based on the RSSI calibration value and / or the preset signal power value, the steps of generating the RSSI parameter calibration command and judging the RSSI parameter deviation value will be repeated until the RSSI parameter deviation value is within the preset RSSI deviation range, thus obtaining the standard value of the RSSI parameter.

[0064] If the target performance parameter is a power parameter, the test platform will send a power parameter calibration command to the standard RF system, causing the standard RF system to send a target RF signal that meets the preset signal power value. For example, the standard RF system will transmit a single-carrier signal at a frequency point based on the initial power value of 100 provided by the test platform. The test platform can measure the actual RSSI value transmitted by the standard RF system, and then calculate the actual power value based on the actual RSSI value. Based on the initial power value and the actual power value, the power deviation value is calculated and compared with the preset power deviation range. If the power deviation value is not within the preset power deviation range, the initial power value is calibrated based on the power deviation value. Based on the power calibration value and / or the preset signal power value, the steps of generating the power parameter calibration command and judging the power parameter deviation value are repeated until the power parameter deviation value is within the preset power deviation range, thus obtaining the standard value of the power parameter.

[0065] If the target performance parameter is a sensitivity parameter, the test platform will send a sensitivity parameter calibration command to the standard RF system, causing the standard RF system to send a target RF signal that meets the preset signal power value, determine the number of received data packets corresponding to the received RF signal, and feed it back to the test platform. After receiving the number of received data packets from the standard RF system, the test platform will calculate the data packet number deviation value based on the number of received data packets and the initial number of data packets. The data packet number deviation value will be compared with the preset data packet number deviation range. If the data packet number deviation value is not within the preset data packet number deviation range, the initial value of the data packet number will be calibrated based on the data packet number deviation value, and the preset signal power value will be adjusted. Based on the power calibration value and / or the adjusted preset signal power value, the steps of generating the sensitivity parameter calibration command and judging the data packet number parameter deviation value will be repeated until the sensitivity parameter deviation value is within the preset sensitivity deviation range, thus obtaining the standard value of the sensitivity parameter (standard data packet number) and the calibrated preset signal power value.

[0066] If the target performance parameter is a voltage parameter, the test platform will send a voltage parameter calibration command to the standard RF system. After transmitting the radio frequency signal, the standard RF system will measure the actual voltage value, calculate the voltage deviation value based on the voltage standard value and the actual voltage value, and feed it back to the test platform. The test platform will compare the voltage deviation value with the preset voltage deviation range. If the voltage deviation value is not within the preset voltage deviation range, the initial voltage value will be calibrated based on the voltage deviation value. Based on the voltage calibration value and / or the preset signal power value, the steps of generating the voltage parameter calibration command and judging the voltage parameter deviation value will be repeated until the voltage parameter deviation value is within the preset voltage standard value.

[0067] Step 308: Determine whether each performance parameter has been calibrated.

[0068] In an optional embodiment of the present invention, after the current target performance parameter has been calibrated, its calibration status can be updated to calibration complete for use in subsequent calibration judgments. If it is determined that there are still performance parameters that have not been calibrated, step 309 can be executed; if all performance parameters have been calibrated, step 310 can be executed.

[0069] Step 309: Select the next performance parameter as the target performance parameter.

[0070] In another optional embodiment of the present invention, after selecting the next performance parameter as the target performance parameter, steps 302-307 can be repeated to obtain the standard value of the next performance parameter.

[0071] Step 310: Output a calibration success message.

[0072] In this embodiment of the invention, a calibration success notification can be displayed on the test platform's screen, allowing calibration personnel to promptly ascertain the calibration completion status. Simultaneously, the standard values ​​of various performance parameters can also be displayed on the screen.

[0073] In another optional embodiment of the present invention, the present invention also supports calibration anomaly or calibration timeout functions. That is, after generating the target performance parameter calibration instruction, the method further includes: detecting whether the actual value of the parameter or the parameter deviation value is obtained; if the actual value of the parameter or the parameter deviation value is not obtained, determining whether the duration of not obtaining the actual value of the parameter or the parameter deviation value exceeds a preset timeout time; if the duration of not obtaining the actual value of the parameter or the parameter deviation value exceeds the preset timeout time, outputting a calibration timeout prompt message and stopping calibration.

[0074] In another specific embodiment of the present invention, in order to realize the automatic switching of calibration of different performance parameters, the step of selecting the next performance parameter as the target performance parameter may further include: when the target performance parameter is calibrated, triggering the execution of a preset asynchronous callback function of the target performance parameter to select the next performance parameter from the local test platform to be determined as the target performance parameter; or, when the target performance parameter is calibrated, triggering a preset calibration completion notification of the target performance parameter, so that the preset task scheduler selects the next performance parameter from the local test platform to be determined as the target performance parameter according to the triggered preset calibration completion notification.

[0075] In this embodiment of the invention, in order to enable testers to know the test results in a timely manner and to facilitate subsequent testing, the test platform calibration method for the RF system further includes: displaying the parameter deviation value and the parameter standard value of the target performance parameter on the test platform, and saving the parameter deviation value of the target performance parameter to the local memory of the test platform for use in the next test. Furthermore, to ensure the accuracy of the test platform and improve its calibration efficiency, the RF system test platform calibration method also includes: after obtaining the standard values ​​of the target performance parameters, the method further includes: establishing a wireless connection with the RF system under test and performing code pairing; receiving the RF system test command triggered by the user; reading the standard values, preset parameter deviation ranges, and preset signal power values ​​of the performance parameters under test from the test platform according to the RF system test command; generating performance parameter test commands based on the standard values ​​and / or preset signal power values ​​and sending them to the RF system under test, which then processes the target radio frequency signal and generates measured values ​​for the performance parameters under test according to the performance parameter test commands; obtaining the parameter deviation values ​​of the performance parameters under test; determining the test results of the performance parameters under test based on the parameter deviation values ​​and preset parameter deviation ranges; and selecting the next performance parameter and repeating the above steps until all performance parameters are tested.

[0076] This invention provides another method for calibrating a test platform for an RF system. This method enables the establishment of a wireless connection and code pairing with a standard RF system. Upon receiving a user-triggered test platform calibration command, it can read the initial value, preset parameter deviation range, and preset signal power value of the target performance parameters from the test platform. Based on the initial and / or preset signal power values, it generates a target performance parameter calibration command and sends it to the standard RF system, allowing the standard RF system to process the target RF signal and generate actual values ​​for the target performance parameters. It also acquires the parameter deviation value of the target performance parameters, which is determined based on the actual and initial values. Based on the parameter deviation value and the preset parameter deviation range, it calibrates the initial values ​​to obtain the standard values ​​for the target performance parameters. Finally, it selects the next performance parameter as the target performance parameter and repeats the above steps until the standard values ​​for each performance parameter are obtained. In other words, compared with existing technologies, this invention enables the completion of various calibration stages of the test platform based on a standard RF system and a user's "one-click" trigger operation. Throughout the calibration process, the test platform automatically generates calibration instructions for the target performance parameters based on the initial values ​​of the target performance parameters and the preset signal power values. This allows the standard RF system to automatically process the target radio frequency signal, obtain the actual values ​​of the target performance parameters, and then the test platform to obtain the parameter deviation values. Based on the parameter deviation values ​​and the preset parameter deviation range, the initial parameter values ​​are calibrated to obtain the standard values ​​of the target performance parameters. Automatic calibration for any target performance parameter is possible, and during the calibration process, each calibration step can be automatically switched and executed without user intervention or manual confirmation. Furthermore, after the calibration of one target performance parameter is completed, the system can automatically switch to the next performance parameter calibration without user input or manual confirmation. Overall, this greatly simplifies the calibration process of the test platform, thereby improving its calibration efficiency and avoiding inconsistencies caused by manual user calibration.
