Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
First, a conventional test method for multiple antennas in a mobile terminal is described below as a practical example.
For example, taking the implementation of a multi-antenna test in a mobile terminal through a near field test as an example, a plurality of test probe antennas are placed in a shielded darkroom, the mobile terminal to be tested is fixed at a certain position to perform a radiation or reception test, and a test result is compared with a reference machine (such as a golden machine, which can achieve standard values required by international specifications in various radio frequency) to determine whether the mobile terminal to be tested passes the test. The near field test has small distance measurement, can be made smaller in a bar shielding darkroom, and occupies small space.
For example, as shown in fig. 1, in the test process, the test probe antenna corresponding to different antennas and systems is switched by the radio frequency switch to test the transceiving performance of the tested mobile terminal. In fig. 1, the control and data transmission of the mobile terminal to be tested may be performed by the USB, which controls the mobile terminal to be tested to perform the tests of WIFI, bluetooth and mobile systems (e.g. GSM, WCDMA, LTE, etc.). Optionally, the mobile terminal to be tested may be controlled in a wireless manner, for example, the router WIFI signal performs data interaction with the mobile terminal to be tested through the communication antenna probe, and controls the mobile terminal to be tested to enter test modes of various systems. No matter the mode is controlled by USB or by a router, because each test may need to switch the antennas, the efficiency of serial test will be very low as the number of antennas increases. In the existing near field test, because the test frequency range is wide, the size of a shielding darkroom on a production line is limited, and more test probes cannot be arranged, on the existing production line test, different modes are usually tested by using a plurality of boxes (such as a shared box body of LTE, GSM, LTE, GPS and the like, a single box body of WIFI is tested, and when the traditional LTE or WIFI is tested, the tested mobile terminal cannot be tested and configured in other modes), the test mode not only increases the cost of test equipment, but also increases the test time of a single wireless device, and the efficiency is low.
For another example, taking a mode of implementing a test of multiple antennas in a mobile terminal through a coupling test as an example, as shown in fig. 2, one or more coupling boards or coupling antennas are placed around a mobile terminal to be tested, and all antennas are tested through one coupling antenna, where multiple coupling antennas are placed in order to adapt to a broadband operating condition, for example, one antenna is for one test frequency band. This solution allows the shadow camera to be made small and economical. However, for a multi-antenna tested mobile terminal, the performance of each antenna needs to be tested separately (that is, all antennas cannot be tested simultaneously), and in addition, the coupled antenna or the coupled board is far away from some antennas, the gain is insufficient, and the testing accuracy is not high.
Therefore, the application provides a multi-antenna multi-system parallel test method for the mobile terminal, which can complete the wireless performance parallel test of multiple antennas and multiple systems of the mobile terminal in one test system, thereby greatly reducing the test time and reducing the test cost. In particular, the following describes a method, a system, a computer device and a computer-readable storage medium for testing the antenna performance of a mobile terminal provided by the present application with reference to the accompanying drawings.
Fig. 3 is a flowchart of a method for testing antenna performance of a mobile terminal according to an embodiment of the present application. It should be noted that, in the embodiment of the present application, the mobile terminal may have multiple antennas, and each antenna corresponds to one standard.
It should be further noted that the method for testing the antenna performance of the mobile terminal in the embodiment of the present application may be applied to the system for testing the antenna performance of the mobile terminal in the embodiment of the present application. As an example, the test system may include a shielded darkroom, a signal source device disposed outside the shielded darkroom, and a test terminal. The mobile terminal can be placed in the shielding darkroom and is provided with a plurality of antennas to be tested; a plurality of test probes are further placed in the shielding darkroom, and each test probe is aligned with one antenna to be tested of the mobile terminal to form a one-to-one transmission channel. In addition, each test probe is within the near-field radiation distance of the mobile terminal, and the position of the test probe antenna can be adjusted to find the best test point. As an example, the test terminal may be a computer device, for example, the computer device may be a PC, and the PC controls the multi-antenna multi-mode parallel test on the mobile terminal.
As shown in fig. 3, the method for testing the antenna performance of the mobile terminal may include:
In an embodiment of the present application, the multiple antennas to be tested may include a mobile network type antenna and at least one non-mobile network type antenna. As an example, the mobile network type antenna may include a GSM type antenna, a WCDMA type antenna, an LTE type antenna, and the like; the non-mobile network type antenna can comprise a WIFI type antenna, a GPS type antenna, a Bluetooth type antenna and the like.
That is to say, when the wireless performance of the mobile terminal is tested, it may be determined which antennas in the mobile terminal are tested in parallel, and the test probes corresponding to the antennas to be tested are determined, and the positions of the test probes are adjusted, so that the test probes conform to the tested positions, and signals can be stably received and transmitted. As an example, the present application includes, but is not limited to, the following standard parallel testing: the WIFI system antenna and the mobile network system antenna are tested in parallel; the WIFI system antenna, the Bluetooth system antenna and the mobile network system antenna are tested in parallel; and the WIFI system antenna, the GPS system antenna, the Bluetooth system antenna and the mobile network system antenna are tested in parallel, and the like.
And 320, configuring the mobile terminal to enter a mobile mode test mode, and controlling the mobile terminal to start a corresponding function module according to a network mode corresponding to at least one non-mobile network mode antenna.
In this step, the control and data interaction may be performed on the mobile terminal through a USB data line, or may also be performed on the mobile terminal in a wireless manner.
In an embodiment of the application, a USB connection with the mobile terminal may be established through a USB data line of a universal serial bus, and after detecting a USB signal, the mobile terminal is configured to enter a mobile mode test mode through the USB connection. That is, the mobile terminal can be configured to be in a mobile mode test mode through the USB data line, so as to perform a normal mobile mode test.
In another embodiment of the present application, a wireless communication connection with a mobile terminal may be established through a wireless signal, and the mobile terminal is configured to enter a mobile mode test mode through the wireless communication connection. That is, the mobile terminal can be configured to be in the mobile mode test mode in a wireless manner, so as to perform a normal mobile mode test.
As an example, the wireless signal is a WIFI signal and the wireless communication connection is a WIFI communication connection. In an embodiment of the present application, the specific implementation process of establishing a wireless communication connection with a mobile terminal through a wireless signal and configuring the mobile terminal to enter a mobile standard test mode through the wireless communication connection may be as follows: and establishing WIFI communication connection with the mobile terminal through a WIFI hotspot signal generated by the router, and configuring the mobile terminal to enter a mobile mode test mode through the WIFI communication connection. That is to say, the mobile terminal can be connected to the WIFI hotspot signal generated by the router, so that the mobile terminal can normally communicate with the router, and thus, the mobile terminal can enter a mobile mode test mode through a signaling WIFI channel connected between the router and the mobile terminal, so that the mobile terminal can normally test a mobile network mode signal.
In the embodiment of the application, because the mobile terminal antenna performance test method of the embodiment of the application is that the mobile terminal realizes the multi-antenna multi-system parallel test in the mobile system test mode, in order to realize the test of other non-mobile network system antennas, the mobile terminal does not need to enter a special antenna system test mode but continues to be kept in the mobile system test mode, and only the functional module corresponding to the non-mobile network system antenna needs to be started, so that the receiving performance test of the corresponding system antenna in the mobile terminal can be ensured. For example, taking a parallel test of the WIFI system antenna and the mobile network system antenna as an example, when the mobile terminal is configured to enter the mobile system test mode, the WIFI function module of the mobile terminal needs to be started, so that the WIFI antenna of the mobile terminal can be normally tested.
Optionally, after determining which antennas of the mobile terminal need to be tested, the signal source device may be controlled to output system test signals corresponding to the antennas at the same time. For example, taking a parallel test of a WIFI system antenna and a mobile network system antenna as an example, the signal source device may be controlled to simultaneously output a mobile network system signal and a WIFI hotspot test signal; taking a WIFI system antenna, a Bluetooth system antenna and a mobile network system antenna for parallel testing as an example, the signal source device can be controlled to simultaneously output a mobile network system signal, a WIFI hotspot test signal and a Bluetooth pairing test signal; taking the parallel test of the WIFI system antenna, the GPS system antenna, the Bluetooth system antenna and the mobile network system antenna as an example, the signal source device can be controlled to simultaneously output a mobile network system signal, a WIFI hotspot test signal, a Bluetooth pairing test signal and a GPS test signal.
As an example, when the plurality of antennas to be tested include WIFI antennas, the signal source device may be controlled to simultaneously generate hotspot test signals of different WIFI frequency bands. That is to say, when the WIFI antenna in the mobile terminal is also tested together, since the WIFI signals include WIFI signals of 2.4G, 5.8G and other frequency bands, in order to reduce the testing time, the signal source device may be controlled to simultaneously generate hotspot testing signals of different WIFI frequency bands, so that the WIFI signals of multiple frequency bands may be tested at one time.
And 340, in the mobile mode test mode, performing performance test on the mobile network mode antenna according to the mobile mode test signal, and simultaneously performing performance test on a corresponding mode antenna in the mobile terminal according to at least one non-mobile mode test signal.
That is to say, when the mobile terminal is in the mobile mode, the mobile network mode antenna of the mobile terminal can be tested for the transceiving performance according to the mobile mode test signal output by the signal source device. Meanwhile, the receiving performance test of the corresponding system antenna in the mobile terminal can be realized based on the functional module corresponding to the non-mobile system of the mobile terminal.
For example, taking a parallel test of the WIFI system antenna and the LTE mobile system antenna as an example, when the mobile terminal is in an LTE test mode, the LTE mobile system antenna of the mobile terminal may be subjected to a transmit-receive performance test according to an LTE mobile system test signal output by the signal source device. Meanwhile, the signal source device can output WIFI hotspot test signals, so that the mobile terminal can scan the WIFI hotspot test signals output by the signal source devices based on the WIFI functional module of the mobile terminal, and further can test the receiving performance of a WIFI antenna in the mobile terminal. For WIFI, the receiving performance only needs to be tested due to the fact that the same-frequency signals are received and transmitted, and therefore the WIFI performance of the mobile terminal can be evaluated by testing the receiving performance of the WIFI antenna of the mobile terminal.
In an embodiment of the present application, the at least one non-mobile test signal includes a WIFI hotspot test signal. In an embodiment of the present application, a specific implementation process of performing a performance test on a corresponding standard antenna in a mobile terminal according to at least one non-mobile standard test signal may be as follows: the WIFI performance of the WIFI antenna in the mobile terminal on the current channel is tested based on the WIFI communication connection, the signal source device is controlled to output WIFI hotspot test signals of other frequency bands, and the WIFI performance of the WIFI antenna on the channels of the other frequency bands is tested according to the WIFI hotspot test signals of the other frequency bands.
For example, a WIFI system antenna and an LTE system antenna are tested in parallel, and a router is used to control a mobile terminal, where a control signal of the mobile terminal is from the router, and a WIFI hotspot signal generated by the router and a WIFI hotspot test signal generated by a signal source device are combined (or separated into two separate paths), and then transmitted to the mobile terminal through a test probe antenna. The test probe position within the shadow booth can be adjusted to find the best test point. And connecting the mobile terminal to the WIFI hotspot signal generated by the router, so that the mobile terminal can normally communicate with the router. And configuring the mobile terminal to enter an LTE system test mode through a signaling WIFI channel connected between the router and the mobile terminal, so that the mobile terminal can normally perform LTE signal test. During the test, a signaling channel established between the router and the mobile terminal directly tests the WIFI performance of the mobile terminal on the current channel. The other channels are WIFI hotspot test signals generated by the signal source device, specifically, the signal source device generates a WIFI Beacon signal, and the mobile terminal receives the WIFI hotspot transmitting signal in a searching mode, so that the receiving performance of the mobile terminal is tested.
When a plurality of antennas to be tested of the mobile terminal are tested, the signal source device can be controlled to switch between a mobile network type test frequency band and a non-mobile network type channel until all frequency band channel tests are completed. For example, taking a parallel test of the WIFI system antenna and the LTE system antenna as an example, the LTE test frequency band and the channel of the WIFI hotspot may be switched until all tests are completed, so as to complete the performance test of the LTE antenna and the WIFI antenna in the mobile terminal.
It should be noted that, in the embodiment of the present application, the test probe in the shielding darkroom may be a broadband probe, which can basically cover all frequencies of the production line terminal test, and the antenna does not need to be switched, and the test of all systems can be completed in one test shielding darkroom. The method and the device can be also suitable for the parallel test modes of the GPS, the Bluetooth, the GSM, the WCDMA, the 5G NR and other mobile systems.
According to the method for testing the antenna performance of the mobile terminal, a plurality of antennas to be tested of the mobile terminal are determined; the plurality of antennas to be tested comprise a mobile network type antenna and at least one non-mobile network type antenna; the method comprises the steps of configuring a mobile terminal to enter a mobile mode test mode, controlling the mobile terminal to start a corresponding function module according to a network mode corresponding to at least one non-mobile network mode antenna, then controlling a signal source device to output multiple test signals at the same time, wherein the multiple test signals comprise a mobile mode test signal and at least one non-mobile mode test signal, and performing performance test on the mobile network mode antenna according to the mobile mode test signal and performing performance test on the corresponding mode antenna in the mobile terminal according to the at least one non-mobile mode test signal in the mobile mode test mode. The mobile terminal is controlled to enter a mobile mode test mode, and the signal source device is controlled to simultaneously output a mobile mode test signal and at least one non-mobile mode test signal, and the functional module corresponding to the non-mobile network mode is started, so that the mobile terminal can simultaneously realize the parallel test of the wireless performance of a plurality of antennas and a plurality of modes in one test system without entering a special non-mobile network mode test but continuously keeping in the mobile mode test mode, the test time is greatly reduced, the test efficiency is improved, and the test cost is reduced.
Fig. 4 is a schematic structural diagram of a mobile terminal antenna performance testing system according to an embodiment of the present application. As shown in fig. 4, the mobile terminal antenna performance testing system 400 may include: a dark room 410, a signal source device 420 and a test terminal 430 are shielded. Wherein the mobile terminal 10 may be placed inside the shielded dark room 410. The mobile terminal 10 has a plurality of antennas to be tested; a plurality of test probes 411 are also placed inside the dark shielded room 410, and each test probe 411 is aligned with one antenna under test of the mobile terminal 10 to form a one-to-one transmission channel. In addition, each test probe 411 is within a near field radiation distance of the mobile terminal 10, and the position of the test probe antenna may be adjusted to find the best test point. The signal source device 420 and the test terminal 430 are respectively disposed outside the dark shielding room 410.
The test terminal 430 is configured to determine multiple antennas to be tested of the mobile terminal 10, where the multiple antennas to be tested include a mobile network type antenna and at least one non-mobile network type antenna; configuring a mobile terminal 10 to enter a mobile mode test mode, and according to a network mode corresponding to at least one non-mobile network mode antenna, controlling the mobile terminal 10 to start a corresponding functional module, and controlling a signal source device 420 to simultaneously output a plurality of test signals, wherein the plurality of test signals include a mobile mode test signal and at least one non-mobile mode test signal; and in the mobile mode test mode, performing performance test on the mobile network mode antenna according to the mobile mode test signal, and simultaneously performing performance test on the corresponding mode antenna in the mobile terminal 10 according to at least one non-mobile mode test signal.
In one embodiment of the application, the test terminal can perform control and data interaction on the mobile terminal through a Universal Serial Bus (USB) data line. In an embodiment of the present application, as shown in fig. 5, the mobile terminal antenna performance testing system 400 may further include: USB data lines 440. In the embodiment of the present application, the test terminal 430 establishes a USB connection with the mobile terminal 10 through the USB data line 440, and configures the mobile terminal 10 to enter a mobile mode test mode through the USB connection after detecting a USB signal. That is, the test terminal 430 can configure the mobile terminal 10 to be in the mobile test mode through the USB data line 440, so as to perform a normal mobile test.
For example, as shown in fig. 5, taking parallel testing of an LTE system antenna and a WIFI system antenna in a shielded darkroom as an example, control and data interaction are performed on a mobile terminal through a USB. The mobile terminal is placed in a shielding darkroom, wave-absorbing materials are arranged in the darkroom, and a plurality of test probe antennas are placed in the darkroom. Each test probe is aligned with one antenna of the mobile terminal to form a one-to-one transmission channel, each test probe is within the near-field radiation distance of the mobile terminal, and the position of the test probe can be adjusted to find the best test point.
In the conventional scheme, WIFI is to be tested separately, and when testing WIFI performance (generally, it is necessary to configure the mobile terminal to be in a non-signaling mode), the mobile terminal cannot be configured to perform LTE testing, and vice versa. In the USB-based control scheme provided in the present application, the multi-antenna multi-system parallel test includes the following steps:
step a, firstly, aiming at the mobile terminal, adjusting the position of a test probe in a darkroom to ensure that the test probe conforms to the test position and can stably receive and transmit signals;
b, configuring the mobile terminal to be an LTE (same step as other mobile systems) system test mode through the USB, and carrying out normal LTE test;
and c, configuring a special signal source device to output a WIFI hotspot test signal, and receiving the signal by the mobile terminal and testing to obtain the power of the WIFI signal. The mobile terminal transmits WIFI signals, and the testing instrument receives the WIFI signals reflected by the mobile terminal and tests the WIFI signals to obtain the WIFI transmitting power of the mobile terminal. The above-mentioned WIFI signals include WIFI signals of 2.4G, 5.8G and other frequency bands (this step can also generate hot spot test signals of different WIFI frequency bands simultaneously, so that the WIFI signals of multiple frequency bands are tested at one time, and the test time is reduced).
And d, switching channels of the LTE test frequency band and the WIFI hotspot until all tests are completed.
In one embodiment of the application, the test terminal can wirelessly interact control and data of the mobile terminal. In an embodiment of the present application, as shown in fig. 6, the mobile terminal antenna performance testing system 400 may further include: a router 450. Router 450 may be used to generate WIFI hotspot signals. In the embodiment of the present application, the test terminal 430 establishes a WIFI communication connection with the mobile terminal 10 through the WIFI hotspot signal generated by the router 450, and configures the mobile terminal 10 to enter a mobile mode test mode through the WIFI communication connection. That is to say, the mobile terminal can be connected to the WIFI hotspot signal generated by the router, so that the mobile terminal can normally communicate with the router, and thus, the mobile terminal can enter a mobile mode test mode through a signaling WIFI channel connected between the router and the mobile terminal, so that the mobile terminal can normally test a mobile network mode signal.
In an embodiment of the present application, the at least one non-mobile test signal includes a WIFI hotspot test signal. In an embodiment of the present application, as shown in fig. 6, the mobile terminal antenna performance testing system 400 may further include: a combiner 460. The combiner 460 is configured to combine the WIFI hotspot signal generated by the router 450 with the WIFI hotspot test signal output by the signal source device 420, and transmit the combined signal to a WIFI antenna in the mobile terminal through the corresponding test probe 411.
In an embodiment of the present application, the at least one non-mobile test signal includes a WIFI hotspot test signal. The specific implementation process of the test terminal 430 performing the performance test on the corresponding standard antenna in the mobile terminal 10 according to the at least one non-mobile standard test signal may be as follows: the WIFI performance of a WIFI antenna in the mobile terminal 10 on the current channel is tested based on the WIFI communication connection; and controlling the signal source device 420 to output the WIFI hotspot test signals of other frequency bands, and testing the WIFI performance of the WIFI antenna in the channels of other frequency bands according to the WIFI hotspot test signals of other frequency bands.
For example, as shown in fig. 6, taking parallel testing of an LTE system antenna and a WIFI system antenna in a shielded darkroom as an example, the mobile terminal is controlled by a router. As shown in fig. 6, the control signal for the mobile terminal comes from the router, where the WIFI hotspot signal generated by the router and the WIFI hotspot test signal generated by the signal source device are combined (or separated into two separate paths), and then transmitted to the mobile terminal through the test probe, in the router-based control scheme provided in the present application, the multi-antenna multi-mode parallel test steps are as follows:
step a, firstly, aiming at a mobile terminal, after the position of a test probe in a darkroom is adjusted, the mobile terminal is connected to a WIFI hotspot signal generated by a router, so that the mobile terminal can normally communicate with the router;
b, configuring the mobile terminal to enter an LTE test mode through a signaling WIFI channel connected between the router and the mobile terminal, so that the mobile terminal can normally perform LTE signal test;
and c, during the test period, a signaling channel established between the router and the mobile terminal directly tests the WIFI performance of the mobile terminal on the current channel. In other channels, a signal source device generates a WIFI hotspot test signal, specifically, the signal source device generates a WiFi Beacon signal, and the mobile terminal receives a WIFI hotspot transmitting signal in a searching mode, so that the receiving performance of the mobile terminal is tested.
And d, switching channels of the LTE test frequency band and the WIFI hotspot until all tests are completed.
It can be seen that, for the above USB-based control scheme and router-based control method, the two schemes have the following obvious features:
1) the WIFI channel realizes the function of a WIFI hotspot through a special signal source device so that the mobile terminal can detect and search the WIFI hotspot, and at the moment, the mobile terminal can simultaneously obtain an LTE test result and a WIFI test result without entering a special WIFI test mode but continuously keeping in an LTE test mode;
2) for WIFI, the same frequency signals are transmitted and received, and only the receiving performance needs to be tested, so that the WIFI performance can be evaluated by the scheme;
3) the test probe is a broadband probe, can basically cover all frequencies tested by a production line terminal, does not need to switch antennas, and can complete the test of all systems in a test shielding chamber;
4) the method and the device are also used for the parallel test modes of the GPS, the Bluetooth, the GSM, the WCDMA, the 5G NR and other mobile systems. For example, if the mobile system, the WIFI and the GPS are to be tested simultaneously, only one test probe antenna needs to be added, and the GPS performance test is performed simultaneously in the mobile system and WIFI measurement process.
According to the mobile terminal antenna performance test system provided by the embodiment of the application, the wireless performance parallel test of a plurality of antennas and a plurality of modes can be realized simultaneously, each test probe corresponds to one antenna to be tested, the information of each antenna in the mobile terminal can be quickly obtained, and in the parallel test, a special signal source device is used, so that a plurality of test modes (such as mobile signals, WIFI, Bluetooth, GPS and the like) can be tested simultaneously, the test time is greatly reduced, the test efficiency is improved, and the test cost is reduced.
