For clarity and brevity of description of the following embodiments, a brief description of implementation of a radio frequency test method is first given:

in the production of consumer electronics, calibration and comprehensive measurement of the radio frequency of the product are an integral part. The conventional test mode in the automatic test system on the production line depends on the product application software instruction, so that when different types of radio frequency test modes based on the product application software instruction use the same series of chips, the different types of products can be used by different types of products due to the difference between the model product application software and developers, and the products need to be repeatedly input for load debugging in the automatic test, the product application software has no inherited attribute of iterative optimization, and the stability and efficiency reduction risk and the like are caused by each change of the product application software. The existing radio frequency test method has at least the following defects:

1. The load is repeatedly input, namely the chips of the same series are repeatedly developed and debugged by an automatic software engineer;

2. repeated verification of stability, namely depending on product application software instructions, researching and developing/clients issue new version product application software instructions, and the radio frequency test is affected by different versions of product application software instructions, so that the problem of false detection is caused, and unified and stable versions cannot be realized;

3. the difference of test efficiency, that is, the same series of chips, has different instruction operation and flow time, mainly different functional design contents of product application software, so that the instruction test on an automatic test system is caused, and the instruction of the product application software must be adapted. That is, assuming that the product A1 uses the B chip and the product A2 uses the B chip, because the product application software instructions of the product A1 and the product A2, such as the number, the type and the delay of the execution instructions reaching the test mode, the instruction test on the automated test system may need to be separately designed for the product A1 and the product A2 to adapt to the instructions of the product application software so as to realize the radio frequency test. On one hand, the radio frequency test efficiency of the same chip is low, and on the other hand, the multiplexing rate of the same chip for the radio frequency test is low because different products need to use different product application software instructions to finish the radio frequency test. Based on the problems, the radio frequency test method provided by the application can separate the dependence of the product application software instruction from the radio frequency test, but can realize the same effect in production.

The application relates to a radio frequency test method, which is applied to a radio frequency test system, wherein the radio frequency test system comprises a test product and a test instrument, and the test instrument obtains test software corresponding to the product to be tested in the test product; determining all test items in the test software in a preset state, and determining control instructions based on the test items in sequence; determining sequence information of the control instructions, and generating test control flow information based on the sequence information and the control instructions; the preset state refers to a state of a chip layer of the product to be tested based on a preset handshake mode; and carrying out radio frequency test on the product to be tested according to the test control flow information to obtain a radio frequency test result. The method for testing the radio frequency of the product to be tested can directly realize the radio frequency test of the product to be tested based on the preset handshake mode in the state of the chip layer of the product to be tested and the test instrument, thereby further avoiding the phenomenon that the radio frequency test can be realized only by using the product application software instruction corresponding to the product to enter the test mode, further avoiding the phenomenon of non-standardization of the product application software instruction.

Based on the hardware structure, the embodiment of the radio frequency test method is provided.

The embodiment of the application provides a radio frequency test method, which is applied to a radio frequency test system, wherein the radio frequency test system comprises a test product and a test instrument, and referring to fig. 2, fig. 2 is a flow diagram of the radio frequency test method, and the radio frequency test method comprises the following steps:

step S10, test software corresponding to a product to be tested in the test products is obtained;

in this embodiment, in the radio frequency test system, the test software SOFT is determined for the test product, where SOFT is an automated test software tailored by LabView in combination with the test requirements. The test software needs to meet any combination test of the test item content capable of supporting BREDRBLE; modification settings that can support arbitrary standards; any one-to-four test can be supported; the comprehensive measurement of various radio frequency instruments can be supported; the display of the result table can be supported; test log local printing may be supported; can support interfacing with a company's internal MES (manufacturing execution System) system. Referring to fig. 8, fig. 8 is a further test schematic diagram of a radio frequency test method, and the designed test software SOFT may finally generate the selection page in fig. 8, so that any combination test, any standard modification setting, etc. of the contents of the test items of the bredble may be selected by the user for different test products based on the selection of the radio frequency test steps, where BREDR is a classical bluetooth mode, BLE is a bluetooth low energy mode, and the BREDR and BLE respectively correspond to the test items of different radio frequency tests. The radio frequency test method of the application can also be referred to as a Bluetooth radio frequency test method, and the Bluetooth connection is used for further testing the Bluetooth radio frequency test system, so that when the radio frequency test is performed on the product, a user can select the selection page in FIG. 8, and further, the test software corresponding to the product to be tested in the test product can be determined. Referring to fig. 9, fig. 9 is a schematic diagram of a testing step of the radio frequency testing method, and the radio frequency control of the test software to the product to be tested is implemented by selecting a step of the test software by a user. The test products are a plurality of products to be tested, the products to be tested are the products which are tested or are to be tested in the test products, and the test software is an instruction for controlling the test instrument to test the test products. And furthermore, the test software of the product to be tested can be determined, and a basis can be provided for the radio frequency test of the product to be tested based on the test software.

Step S20, determining all test items in the test software in a preset state, and determining control instructions based on the test items in sequence;

step S30, determining sequence information of the control instruction, and generating test control flow information based on the sequence information and the control instruction; the preset state refers to a state of a chip layer of the product to be tested based on a preset handshake mode.

In this embodiment, after the test software is determined, test control flow information is determined according to the test software in a preset state, where the preset state refers to a state of the chip layer of the product to be tested based on a preset handshake mode, that is, the entire test flow is handshake between the test instrument and the chip layer of the product to be tested (handshake is divided into different handshake times and different test functions, where the handshake is performed after the test software is acquired due to handshake between the product to be tested and the test instrument based on the times of the handshake and the function to be tested of the product to be tested, and what is described in the second embodiment, however, the step of determining the test control flow information of the product to be tested is performed only after the handshake in any mode, and by performing further refinement control on the acquired test software in the preset state (that is, in the handshake state), the test control flow information refers to items of radio frequency test in the test software, and the like, and the different items of radio frequency test correspond to different control modes and different handshake modes (different handshake modes and different handshake modes). It should be noted that, all test items in the test software are determined in the preset state, only the process of establishing the preset state is different, such as a handshake mode of private protocol, signaling, BLE pairing and the like, and the process of determining the test items in the preset state is the same, and the test items selected by the test software user are determined, such as the content of the user checking the page in fig. 8 as the test items. After handshake between the test instrument and a chip layer of a product to be tested, all test items in test software are determined, control instructions are sequentially determined based on the test items, sequence information of the control instructions is determined, and finally test control flow information is generated based on the sequence information and the control instructions, wherein the control instructions comprise control mode instructions and control test instructions. The control instruction refers to a control mode of the test item, a mode of entering the controller and a communication mode, the sequence information refers to sequence information of testing the test item, the control mode instruction refers to a control instruction for controlling the product to be tested to enter different modes, and the control instruction refers to a control instruction for controlling the product to be tested to realize radio frequency testing in different modes. For example, the interface of fig. 8 determines test items to be tested, generates the test items, determines the sequence of the test items by dragging of fig. 9, and then generates a control mode command and a control test command. And then based on the sequence corresponding to the test items and the control instruction, generating test control flow information, namely, based on the test control flow information, sequentially controlling the products to be tested to realize the test of the test items, so that the efficiency of radio frequency test can be ensured.

The test software controls the radio frequency instrument based on the control protocol SCPI layer, the radio frequency instrument and the DUT (product under test) chip layer are controlled based on the bluetooth protocol stack LMP layer, a connection is established through a proprietary protocol, the test software program control test instrument of the automated test system selects a test mode and a test item, triggers and starts a test, and controls related peripherals and result data analysis and judgment. The DUT is a product to be tested, the test mode and the test item refer to the mode of controlling the product to be tested and the item to be tested, and the control of the related peripheral devices refers to the control of activating and starting up the product to be tested, and the control of starting up the product to be tested through the GPIO port can be realized. Taking the first connection as an example here: the test INSTRUMENT establishes connection with the DUT chip layer through a private protocol, (the test software is SOFT, the product to be tested is DUT, the radio frequency INSTRUMENT is INSTRUMENT), the private protocol is integrated in the firmware of the DUT, and the private protocol can be burnt into the firmware of the DUT and the firmware of the INSTRUMENT in advance. During production test, the DUT is started and in a user mode, and INSTRUMENT is in a default mode after the DUT is started. The SOFT may optionally select the BREDRBLE test item at the interface of FIG. 8, and the SOFT controls INSTRUMENT in a new mode, i.e., a mode that can handshake with the DUT. Referring to fig. 7, fig. 7 is a schematic test diagram of a radio frequency test method, in which information about a model, a lot, a trend, a use of a test instrument, a component, a station passing, etc. of a product to be tested is illustrated, so that a physical address can be set in the diagram, and connection of the product to be tested can be realized. By sending the physical address of the DUT to the INSTRUMENT, a state is established in which the DUT handshake OK. Further, a control instruction INSTRUMENT in SOFT informs the DUT of a test mode to be entered through a private protocol; meanwhile, a control instruction INSTRUMENT in SOFT informs the content of a test item required by the DUT through a private protocol; after the radio frequency test is finished, SOFT controls INSTRUMENT, and the DUT is informed of the state after the test is finished and the connection is disconnected through a private protocol; and controlling the INSTRUMENT to disconnect the product to be tested and collecting the test result so as to complete the radio frequency test of the product to be tested. Furthermore, the radio frequency test can be realized by establishing connection between the test instrument and the DUT chip layer through a private protocol, the efficiency of the radio frequency test of the product can be improved, and by using the method, the influence of application software of different products can be eliminated through the communication of the chip layer, so that the reusability of the test software is also improved.

And S40, performing radio frequency test on the product to be tested according to the test control flow information to obtain a radio frequency test result.

In this embodiment, after determining the test control flow information, the product to be tested is subjected to radio frequency test according to the test control flow information to obtain a radio frequency test result, and because the test control flow information determines the mode control and the handshake mode, the product to be tested is subjected to radio frequency test based on the test control flow information. The radio frequency test result is a test result obtained by performing radio frequency test on the product to be tested based on the test control flow information. Referring to table 1, table 1 shows the contents of the radio frequency test items and the reference standard.

TABLE 1

The above table 1 is not limited to the content and the reference standard of the radio frequency test, but may be other content and reference standard of the radio frequency test. In the embodiment, the product firmware and the instrument firmware are added with the private protocol, and after a series of operations of the test software control instrument, the product calibration of the production line and the test of the content of the related test item of the comprehensive test are completed, so that the dependence of the product application software can be separated. The same series of chips, the automatic test software of the production line can realize the completion of one test software; meanwhile, development load of an automation end and stability verification of the radio frequency test of the product are reduced. Because the private protocol is integrated in the firmware of the product, the production line does not need repeated burning; it is worth to say that the test software provides the required test mode for the next station after the test is completed and the test control is performed without using complicated product application software, so that the test efficiency of the production line can be improved.

Further, referring to fig. 3, in this embodiment, when a product needs to be tested by radio frequency, by selecting a device port, a configuration file, and station passing information, and initializing a test program, the device port refers to a port of a test instrument and a port of the test product, the configuration file refers to a configuration file inside the test instrument and the test product, and the station passing information refers to station passing information of the whole test product, such as being at a radio frequency test site at present. And after the preparation work is configured, the test product, namely the product to be tested, is tested. Through detecting whether the shielding box is closed, the shielding box can be detected through the sensor, and meanwhile, whether a product is put well or not can be checked through the grating, so that the shielding box is prepared for starting radio frequency detection. After the preparation work is finished, the product to be detected is activated, namely the product to be detected is connected with the testing instrument based on the private protocol, and the starting up of the product to be detected is controlled. Meanwhile, a user can detect and control products to be detected based on a matrix switch in the radio frequency test system, referring to fig. 5, fig. 5 is a schematic diagram of a frame of the radio frequency test system, the matrix switch refers to a single-pole double-throw switch 1 and a single-pole double-throw switch 2 in the diagram, as shown in the diagram, four test products DUT1-DUT4 are respectively connected with the single-pole double-throw switch 1 and the single-pole double-throw switch 2, and further DUT1, DUT2, DUT3 and DUT4 can be selectively tested, and the single-pole double-throw switch 1 and the single-pole double-throw switch 2 can be controlled to be switched on and off through serial ports/network ports of a host computer. A rack holding DUTs and a shielded enclosure sealing the rack are included at each location where the DUTs are tested. Because the comprehensive tester can measure the radio frequencies of two DUTs at the same time, when the design in the figure is adopted, such as the DUT1 and the DUT3 carry out radio frequency test, the single-pole double-throw switch 1 or the single-pole double-throw switch 2 controls the radio frequency lines output by the two to be connected with the two measured radio frequency lines of the comprehensive tester, and then the radio frequency test of the DUT1 and the DUT3 is realized; while the user can load test chips in the racks 2 and 4. After the DUT1 and the DUT3 are tested, the single-pole double-throw switch 1 or the single-pole double-throw switch 2 controls the radio frequency wires output by the DUT2 and the DUT4 which are transferred at the moment to be connected with the two measured radio frequency wires of the comprehensive tester, so that the radio frequency test of the DUT2 and the DUT4 is realized, and meanwhile, the test chips in the rack 1 and the rack 3 are continuously replaced, so that the efficiency of the radio frequency test can be greatly improved in practical application. And finally uploading the result of the radio frequency test to the host computer through the network port so as to ensure that the user can check later. After the control process of the whole matrix switch, referring to fig. 3, the chip of the product to be tested can be selected through the control of the matrix switch, so that the instrument and the product are handshaking, that is, the instrument such as the comprehensive tester and the chip layer of the product to be tested are handshaking, and further the frequency offset calibration and comprehensive test such as frequency calibration, signal intensity calibration, comprehensive test of amplitude and sensitivity and the like of the product to be tested are realized through the instrument such as the comprehensive tester and the like. And after the calibration and comprehensive measurement are completed, the connection between the product and the instrument is disconnected, and the product returns to a specified mode through a software instruction, wherein the specified mode can be a shutdown mode and the like, so that the radio frequency test of the whole product to be tested is completed. The data analysis and processing can be performed based on algorithm or manually, the result and the test data of the product to be tested are uploaded to MES, and the end of the test is displayed so as to be convenient for entering the radio frequency test of the next product to be tested. Based on the radio frequency test after the product and the instrument handshake, the phenomenon that the radio frequency test can be realized only by entering a test mode by using the product application software instruction corresponding to the product can be avoided, and the efficiency of the radio frequency test of the product can be greatly improved by carrying out the radio frequency test after the product and the instrument handshake.

Referring to fig. 6, fig. 6 is a schematic diagram of a test framework of a radio frequency test method, illustrating a test module after the entire product and instrument handshake, where the test module includes an illustration of the radio frequency test module based on the product and instrument handshake, and does not include an actual test sequence.

The radio frequency test method is applied to a radio frequency test system, the radio frequency test system comprises a test product and a test instrument, and the test instrument obtains test software corresponding to the product to be tested in the test product; determining all test items in the test software in a preset state, and determining control instructions based on the test items in sequence; determining sequence information of the control instructions, and generating test control flow information based on the sequence information and the control instructions; the preset state refers to a state of a chip layer of the product to be tested based on a preset handshake mode, wherein the preset handshake mode comprises private protocol, signaling and BLE pairing; and carrying out radio frequency test on the product to be tested according to the test control flow information to obtain a radio frequency test result. The method for testing the radio frequency comprises the steps of carrying out radio frequency testing on the basis of testing software corresponding to a product to be tested under the state of a chip layer of the product to be tested and a testing instrument through a preset handshake mode, so that the phenomenon that the radio frequency testing can be realized only when a product application software instruction corresponding to the product enters a testing mode can be avoided.

Further, based on the first embodiment of the radio frequency testing method of the present invention, a second embodiment of the radio frequency testing method of the present invention is provided, wherein the testing software includes a product physical address of the product to be tested, and before the step of determining all the testing items in the testing software in the preset state, the method includes:

step S21, activating the product to be tested based on the physical address of the product, and detecting whether the current mode of the product to be tested is a user mode or not;

step S22, if the current mode of the product to be tested is a user mode, the chip layer of the product to be tested is held by a hand in a preset handshake mode, and the step of determining all test items in the test software in a preset state is executed;

in this embodiment, since the test software includes the product physical address of the product to be tested, the product to be tested can be activated based on the product physical address, and whether the current mode of the product to be tested is the user mode can be detected. And when the current mode of the test product is a user mode, the chip layer of the product to be tested and the test instrument are held based on a preset handshake mode, and the step of determining all test items in the test software in a preset state is executed. The physical address of the product refers to the physical address of the product to be tested, and the product to be tested is controlled to be activated and started and then subjected to subsequent radio frequency test based on GPIO (General-purpose input/output), the user mode refers to the conventional mode of using the product by a consumer, and the user mode can be directly handshaking with a radio frequency instrument and mode conversion, and corresponding test is executed, so that the test efficiency of the radio frequency test can be improved.

Step S23, if the current mode of the product to be tested is not the user mode, triggering a preset restarting instruction, and executing the step of handshake the chip layer of the product to be tested based on a preset handshake mode after executing the restarting instruction.

In this embodiment, when the current mode of the product to be tested is not the user mode, a preset restart instruction is triggered, and after restarting the product to be tested based on the restart instruction, a step of handshaking the chip layer of the product to be tested based on a preset handshaking mode is performed. The restarting instruction is an instruction for restarting the product to be tested, and then the product enters a user mode after restarting and is subjected to radio frequency test after being held by a radio frequency instrument.

step S25, if the chip layer of the product to be tested and the test instrument are handshaking for the first time, handshaking the chip layer of the product to be tested based on the private protocol;

In this embodiment, when the chip layer of the product to be tested is handshake-held based on a preset handshake mode, the chip layer of the product to be tested and the handshake times of the test instrument are determined. When the chip layer of the test product and the test instrument are subjected to first handshake, the chip layer of the test product is subjected to handshake based on a private protocol, and then radio frequency test is performed based on test software after handshake, control by complex product application software instructions is not needed, and further the efficiency of radio frequency test of the product can be improved.

Step S26, if the chip layer of the product to be tested and the test instrument are not first handshaking, determining a test option corresponding to the test software;

step S27, if the test option is a BREDR mode corresponding test item test, the chip layer of the product to be tested is held by the hand based on the signaling;

step S28, if the test option is a BLE mode corresponding test item test, the chip layer of the product to be tested is held based on the BLE pairing.

In this embodiment, when the chip layer of the test product and the test instrument are not first handshake, the test option corresponding to the test software is determined, because the radio frequency test only has the BREDR and BLE mode corresponding test item test, and further the test option is determined to be the BREDR mode corresponding test item test, the chip layer of the test product is tested based on signaling handshake, otherwise the test option is the BLE mode corresponding test item test, and the chip layer of the test product is tested based on BLE pairing handshake. The test options can be a BREDR mode corresponding test item and a BLE mode corresponding test item, so that different handshake modes can be determined, and the pertinence of handshake is ensured. That is, when the test instrument handshakes with the product to be tested, the test instrument is converted into a test mode supporting the private protocol during initialization, and when the product to be tested enters the user mode, the private mode is required to be supported. At this time, the handshake needs to satisfy: the primary handshake uses a proprietary protocol; a signaling handshake is used when the BREDR test option is under the test handshake; and (3) repeating the handshake, wherein the BLE mode corresponds to the BLE pairing handshake when the test item tests the option. And furthermore, the accuracy of handshake can be ensured, and meanwhile, the pertinence of handshake is improved, and the efficiency of radio frequency test of products is further improved.
