[0025] DTV (Digital Television) generally has 4 groups of antenna channel interfaces for covering different frequency bands / directions, and facilitating antenna performance testing. However, in actual testing process, the existing testing device needs to test the performance indicators of the 4 groups of antennas in sequence, and during this period, the testing device with large volume needs to be moved constantly, and manual switching is prone to the phenomenon that the antenna and the testing device are not installed in place, and manual multiple plugging and unplugging of the antenna is also prone to the phenomenon that the pins are offset, which is prone to cause rapid wear of the interface of the testing device.

[0026] Therefore, the present application provides an antenna channel testing method, so as to improve the operation convenience of the tester, improve the testing efficiency, and prolong the service life of the interface of the testing device.

[0027] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0028] Figure 1 An exemplary flowchart of the antenna channel testing method of some embodiments of the present application is shown, please refer to Figure 1 The antenna channel testing method shown in the embodiments of the present application can include: In step S101, a port connection event between the antenna harness and the testing device is monitored. In the embodiments of the present application, the port connection event refers to the event that the harness interface of the antenna harness is connected with the port of the testing device. Wherein, the antenna can be a DTV (Digital Television) antenna, and the 4 groups of antenna channels thereof are VHF-L (47~88MHz), VHF-H (174~230 MHz), UHF (470~862 MHz) and L-Band (1.45~1.49 GHz). VHF-L is used to receive VHF (Very high frequency) low frequency band digital television signal, VHF-H is used to receive VHF high frequency band digital television signal, UHF is used to receive UHF (Ultra High Frequency) digital television signal, and L-Band is used for satellite ground point, mobile television, and second UHF diversity.

[0029] In the embodiments of the present application, the four groups of DVT antennas can be fixed together with a male connector (a connector with a center pin or a latch used to plug into a corresponding female connector to complete mechanical locking and electrical conduction) to avoid the dispersion of the antennas, thereby forming an antenna harness. Further, a FAKRA (Fachkreis Automobil, a standardized coaxial connector system designed specifically for automotive and high-frequency radio frequency scenarios) / SMB (SubMiniature version B Plug, a push-in (snap-on) miniature coaxial radio frequency connector) plug can be exemplarily used to realize the connection between the antenna harness and the test device, wherein a micro switch can be arranged in the plug, when the plug is fully inserted, the micro switch is closed, and the DIO (Digital I / O, digital input / output) reads "0"; when the plug is loose or the antenna harness is not connected to the test device, the DIO reads "1", thereby realizing the monitoring of the port connection event between the antenna harness and the test device.

[0030] In step S102, if the port connection event is monitored, the antenna channel switching instruction is determined according to the channel switching truth table. In the embodiments of the present application, a channel switching truth table can be preset, so that the controller can determine the antenna channel switching instruction according to the truth value corresponding to each antenna channel in the channel switching truth table. Exemplarily, assuming that the channel switching truth table is "00" corresponding to ANT1, "01" corresponding to ANT2, "10" corresponding to ANT3, and "11" corresponding to ANT4 in turn, when the port connection event is monitored, the first truth value in the channel switching truth table can be determined as the current antenna channel switching instruction, that is, the current antenna channel switching instruction is "00". After the test of the antenna channel corresponding to ANT1 is successful, the antenna channel switching instruction can be switched to the next truth value "01" of "00" according to the channel switching truth table, thereby continuing to test the antenna channel corresponding to ANT2.

[0031] It can be understood that the above description of the channel switching truth table setting is exemplary, and in actual application, the setting method of the channel switching truth table needs to be determined according to the actual application, and the present application does not make any limitation in this aspect.

[0032] In step S103, in response to the antenna channel switching instruction, the antenna channel to be tested corresponding to the antenna channel switching instruction is turned on, and an antenna connection test and a test port status test are performed on the antenna channel to be tested. In the embodiment of the present application, the antenna channel to be tested refers to the antenna channel currently switched to. Assuming that the current antenna channel switching instruction is "00", the antenna channel to be tested corresponding to the antenna channel switching instruction is the antenna channel corresponding to ANT1. At this time, ANT1 is in the on state, so that the connection between the antenna channel corresponding to ANT1 and the test device can be connected. In addition, to ensure the accuracy of the test, it is necessary to perform an antenna connection test and a test port status test before the test to ensure that the antenna channel is successfully connected and the port connection of the test device is correct.

[0033] In step S104, in response to the antenna connection test and port status test pass information, a test start instruction is issued to the test device. In this embodiment of the present application, the test pass information is generated only after the antenna connection test and port status test have both passed. At this time, the test start instruction can be issued to the test device, so that the test device can respond to the test start instruction to perform a performance test on the antenna channel to be tested.

[0034] The embodiment of the present application monitors the port connection event between the antenna harness and the test device. If a port connection event is detected, the antenna channel switching instruction is determined according to the channel switching truth table. Then, in response to the antenna channel switching instruction, the antenna channel to be detected corresponding to the antenna channel switching instruction is turned on, and the antenna connection detection and test port status detection are performed on the antenna channel to be detected to ensure that the antenna channel connection is successful. Furthermore, the present application can send a test start instruction to the test device in response to the detection pass information of the antenna connection detection and the port status detection, thereby avoiding the need for manual switching when performing performance index tests on each antenna channel of the antenna harness in sequence, reducing the number of plug-in and unplugging times of the test device, reducing the risk of rapid wear of the test device interface, and extending the service life. At the same time, it reduces the complexity of the tester's operation and improves the efficiency of performance testing.

[0035] In general, this application can improve the operating convenience of testers, improve testing efficiency, and extend the service life of the test device interface.

[0036] In some embodiments, the detection process of antenna connection detection and test port status detection can be further designed. Figure 2 The detection process of antenna connection detection and test port status detection is described in detail. Figure 2 An exemplary flow chart showing antenna channel testing methods according to other embodiments of the present application is shown. Figure 2 , the antenna channel testing method shown in the embodiment of the present application may include: In step S201, antenna on detection is performed on the antenna channel to be detected. In the embodiment of the present application, when receiving the antenna channel switching instruction, the controller (such as MCU) can send a query program code to query the antenna carrier-to-noise ratio (CNR, the ratio of carrier power (C) and noise power (N)) of the antenna channel to be detected, and then determine whether the antenna on detection passes based on the antenna carrier-to-noise ratio and the preset carrier-to-noise ratio threshold. The preset carrier-to-noise ratio threshold can be set to 17 dBm. It can be understood that the preset carrier-to-noise ratio threshold can be set in various ways, and in actual application, the preset carrier-to-noise ratio threshold needs to be determined according to the actual application, and the present application does not make any limitation in this regard. Further, in the embodiment of the present application, if the antenna carrier-to-noise ratio is greater than the preset carrier-to-noise ratio threshold, it is determined that the antenna on detection passes.

[0037] In step S202, test port state detection is performed on the antenna channel to be detected. In the embodiment of the present application, the actual channel number of the antenna channel to be detected can be obtained first. Specifically, the signal strength of each antenna channel can be detected, and then the actual channel number corresponding to the antenna channel with a signal strength greater than 30 dBm can be read. Further, the preset channel number corresponding to the antenna channel switching instruction can be determined according to the switching instruction truth table, such as "00" corresponding to ANT1, "01" corresponding to ANT2, "10" corresponding to ANT3, and "11" corresponding to ANT4 in the switching instruction truth table. The first bit in the truth value is the value of the first control terminal CTL_A, and the second bit in the truth value is the value of the second control terminal CTL_B. Then, whether the test port state detection passes can be determined based on the actual channel number and the preset channel number corresponding to the antenna channel switching instruction. In the embodiment of the present application, if the actual channel number is consistent with the preset channel number corresponding to the antenna channel switching instruction, it is determined that the test port state detection passes.

[0038] It can be understood that step S201 and step S202 can be executed simultaneously or sequentially, and the execution order between step S201 and step S202 is not strictly limited in the present application.

[0039] In step S203, in response to the detection pass information of the antenna on detection and the port state detection, a test start instruction is sent to the test device. In some application scenarios, in order to ensure the accuracy of the antenna on detection and the port state detection, when receiving the detection pass information of the antenna on detection and the port state detection, the antenna on detection and the port state detection on the antenna channel to be detected can be performed again in response to the detection pass information of the antenna on detection and the port state detection. When the antenna on detection and the port state detection both pass again, the test start instruction is sent to the test device.

[0040] In an embodiment of the present application, after issuing a test start command to the test device, the antenna channel switching command can be updated according to the channel switching truth table in response to test success information fed back by the test device, resulting in an updated switching command. Exemplarily, the update can be performed based on the order of truth values ​​in the channel switching truth value. For example, after the antenna channel corresponding to ANT1 is tested successfully, the antenna channel switching command can be switched to the next truth value of "00," "01," according to the channel switching truth table, thereby continuing to test the antenna channel corresponding to ANT2. Furthermore, in response to the updated switching command, the antenna channel to be tested corresponding to the updated switching command undergoes antenna connection testing and test port status testing. In response to the antenna connection testing and port status testing passing, a test start command is issued to the test device. Furthermore, in response to test failure information fed back by the test device, an antenna channel failure warning message is generated. Exemplarily, if the test device reports that the antenna channel corresponding to ANT1 has failed testing, the system will generate a warning message indicating a failure in the antenna channel corresponding to ANT1, prompting the tester to address the issue.

[0041] Corresponding to the aforementioned application function implementation method embodiment, the present application also provides an antenna channel testing device and corresponding embodiments. Figure 3 The figure shows a schematic structural diagram of an antenna channel testing device according to an embodiment of the present application. Figure 4 The electrical block diagram of the antenna channel test device according to the embodiment of the present application is shown in FIG. Figure 3 and Figure 4 , the antenna channel testing device shown in the embodiment of the present application may include: The fixture body 1 and the limit baffle 2 are fixed to the side wall of the fixture body 1. The limit baffle 2 is provided with a harness interface 3 for the antenna harness, which is used to connect to the port of the test device 6. The limit baffle 2 can fix the harness interface 3 to prevent unnecessary wear during the insertion and removal of the test device.

[0042] Further, the inner cavity of the tool jig body 1 is provided with a control panel 4 (which can be an MCU, Microcontroller Unit) and a channel switching switch 5. The channel switching switch 5 can be a four-channel radio frequency switch, and the channel switching switch 5 is provided with a signal input end Input for receiving a DTV signal from a DTV signal generator, and a first signal output end ANT1, a second signal output end ANT2, a third signal output end ANT3, and a fourth signal output end ANT4 connected with the wire harness interface 3 (internal wiring connection of the tool jig body 1), and relays can be arranged at the first signal output end ANT1, the second signal output end ANT2, the third signal output end ANT3, and the fourth signal output end ANT4 to control the opening and closing thereof. In addition, the control panel 4 is connected with a first control end CTL_A and a second control end CTL_B of the channel switching switch 5, for the control panel 4 to send switching instructions to the channel switching switch 5.

[0043] For example, when the value of CTL_A is 0 and the value of CTL_B is 0, the first signal output end ANT1 is open, and the other signal output ends are closed; when the value of CTL_A is 0 and the value of CTL_B is 1, the second signal output end ANT2 is open, and the other signal output ends are closed; when the value of CTL_A is 1 and the value of CTL_B is 0, the third signal output end ANT3 is open, and the other signal output ends are closed; and when the value of CTL_A is 1 and the value of CTL_B is 1, the fourth signal output end ANT4 is open, and the other signal output ends are closed.

[0044] In some embodiments, in order to stably control the channel switching switch 5, the channel switching switch 5 is further provided with a power terminal VCC, a first voltage stabilizing resistor R1 and a second voltage stabilizing resistor R2 are connected in series between the power terminal VCC and the first control end CTL_A, and a first node between the first voltage stabilizing resistor R1 and the second voltage stabilizing resistor R2 is connected with the control panel. A third voltage stabilizing resistor R3 and a fourth voltage stabilizing resistor R4 are connected in series between the power terminal VCC and the second control end CTL_B, and a second node between the third voltage stabilizing resistor R3 and the fourth voltage stabilizing resistor R4 is connected with the control panel.

[0045] Under the action of such a device, the tester only needs to confirm that the current channel picture is played normally and then click the confirmation button of the ATE tool to test according to the process, without manually plugging in and out the switching test device, thereby reducing the operation difficulty of the tester, improving the test efficiency, and reducing the error during the connection.
