[0101] An application method of an air unit comprehensive automatic test system of a data link system, remote system parameter configuration, function test and performance test are realized by a test software in a PC host computer, the following functions can be realized by the test software according to the scheme:

[0102] Radio frequency test distribution: can be suitable for different wireless test projects, and can test a plurality of wireless link signals;

[0103] Automatic test is realized: according to different projects, the test instrument needs to be connected, programming modification is carried out, automatic test and product output power recording are realized.

[0104] Specifically, the parameter configuration of the application can be realized in three ways, automatic configuration, manual configuration and automatic and manual combined configuration. Among them, the automatic configuration is realized by selecting the test template and loading the template to realize the parameter configuration; the manual configuration is realized by manually configuring each configuration item; the third automatic and manual combined configuration is to selectively modify some configuration items on the basis of automatic configuration.

[0105] No matter which parameter configuration method, it needs to be loaded or configured according to the parameter configuration process.

[0106] The first step is to confirm the network segment, check whether the IP of the test computer and the IP of the automatic test host are in the same network segment, if they are in the same network segment, it can enter the second step, otherwise the computer IP network segment and the automatic test host IP need to be modified to the same network segment, so as to realize the access connection of the test host through the automatic test software;

[0107] The second step is to configure the number of batch test equipment, according to the number of test air units, the number of test equipment is selected at a time, which can select all 5 equipment, or select 1, 2 or more combinations at a time;

[0108] The third step is to select the frequency point, because different frequency points realize different data link subsystem communication, only when the air unit and the simulated ground radar are set in the same time, the networking communication can be realized;

[0110] The fifth step is to select the power mode, the power mode is divided into high power mode and low power mode, different power modes are used in different scenes; in the indoor laboratory environment, due to the short communication distance, the low power mode can be used; for long distance communication in the field, the high power mode needs to be selected;

[0111] The sixth step is communication mode configuration: the communication mode is divided into synchronous communication mode or asynchronous communication mode, the synchronous communication mode needs the air unit and the ground equipment to be synchronized networking, and the air unit can send data to the ground; the asynchronous communication mode does not need the air unit and the ground equipment to be synchronized, and always sends data to the ground equipment;

[0112] The seventh step is that only when the test parameters are loaded or configured, the function test button appears, and the function test is carried out.

[0113] Further, the automatic function test of the comprehensive automatic test system includes device self-checking, obtaining device number, querying software version number, parameter binding, other function item test and automatic generation of function test report, and the test flow is as shown in Figure 4

[0114] The first step of the function test is the test of the device self-checking function, the device self-checking includes two self-checking items of checking whether the communication between the ground equipment and the air unit is normal and checking whether the secondary power supply of the air unit is normal, and only when the device self-checking is normal, the device number obtaining flow can be entered; if the device self-checking is abnormal, the abnormal situation needs to be handled, and after the handling, the function item test is restarted;

[0115] The second step is obtaining device number, in order to more clearly know the current automatic test air unit number, the unique device number (ID) of the air unit is queried for identification;

[0116] The third step is querying software version number, in order to prevent the device state from being inconsistent due to inconsistent software when testing a batch of products, after confirming the product ID of each air unit, the software version loaded in the current device is queried, when the loaded software is found to be inconsistent, the software needs to be upgraded online again, and then the device self-checking flow is returned;

[0117] The fourth step is to test each function test item of the air unit, and the function test item generally includes uplink and downlink communication function, online upgrade, parameter configuration and the test of the foregoing self-checking, ID number, software version and the like.

[0118] The fifth step is to make a piece-by-piece qualification determination on each test result according to the automatic test flow, and meanwhile, an automatic function test report is output.

[0119] Further, the automatic performance test of the comprehensive automatic test system includes self-checking time, various instrument connection, control and test, waveform test, power test, receiving sensitivity test and the like.

[0120] The first step of the performance test is to connect the air unit UDP and the ground equipment UDP through the comprehensive automatic test PC software.

[0121] ​Second step, when connecting the air unit UDP, power supply remote control can be realized, through the integrated automatic test PC software, selecting the product corresponding to air unit 1 / 2 / 3 / 4 / 5 number, at the same time, selecting the up antenna or down antenna test;

[0122] Third step, testing the air unit power-on self-test time, judging whether the self-test time meets the system requirement or not;

[0123] Fourth step, oscilloscope connection, control and test, through the configuration of oscilloscope IP, such as 192.168.102.168, clicking the connection instruction, connecting to the oscilloscope for configuration, setting the oscilloscope test parameter for waveform test;

[0124] Fifth step, power meter connection, control and test, through the configuration of power meter IP, such as 192.168.102.188, issuing the connection instruction, the power meter can be configured, issuing the configuration power meter command; in order to achieve better measurement effect, the power meter needs to be calibrated, after calibration, the power meter test parameter is configured for pulse width, time delay, transmission power and other performance test;

[0125] Seventh step, according to the automatic test process, each item of performance test result is judged one by one, and the automatic performance test report is output.

[0126] The test system of the application has the following functional effects when applied:
