[0002] Compared to terrestrial network terminal equipment, airborne network terminal equipment has a higher power-on and power-off frequency, and is more prone to abnormal power-off scenarios during normal communication. According to the failure statistics of airborne network terminal equipment, most failures of airborne network terminal equipment occur during the power-on or power-off process. Therefore, the airborne network terminal equipment test platform should support the testing of the power-on and power-off working scenarios of the equipment under test.

[0013] like Figures 1 to 4 The test method for airborne network terminal equipment supporting power control, as shown, is applicable to testing airborne avionics system network terminal equipment in power-on and power-off scenarios using a universal test platform. The universal test platform includes a test console and a power control unit. The test method includes... S101: The general test platform is initialized. After the test console completes the initialization, it sends a power-on command to the power control unit. The power control unit outputs the voltage required by the network terminal device under test according to the power-on command, generates the voltage, and sends a response message to the test console. S102: The test console reads the pre-stored test scripts for power-on and power-off scenarios, and the test console completes the loading of the test scripts; S103: The network terminal device under test is tested in power-on and power-off scenarios; S104: When the network terminal device under test completes the execution of all power-on and power-off commands in sequence, it will send feedback information to the test console. Specifically, the test console sends a test end command to the test unit and the unit under test according to the test script. The test unit and the unit under test end the test and send the test results back to the test console. After all test cases are executed, the test console sends a power-off command to the power management unit. The power control unit stops outputting according to the power-off command, performs a power-off operation on the unit under test, and sends a response message to the test console.

[0014] This method integrates a power control unit into the existing test console, test unit, and unit under test of the traditional airborne network terminal equipment test platform, and designs an interaction protocol suitable for the test console and power control unit to realize automated testing of the power-on and power-off working scenarios of airborne network terminal equipment, thereby improving the automation level of the airborne network terminal equipment test platform.

[0015] In one embodiment, the test console in S103 completes the loading of the test script, including: When the test console performs tests on the network terminal under test according to the test script, the test console sends continuous power-on and power-off commands to the power management unit. The power control unit controls the network terminal device under test to perform power-on and power-off operations at preset frequencies and time intervals using continuous power-on and power-off commands. When the network terminal device under test completes the power-off operation under the control command, the generalized test platform detects whether the communication network of the network terminal device under test is abnormal. If so, it feeds back a fault signal; if not, it executes the power-on and power-off commands again, and so on, until all power-on and power-off commands are executed.

[0016] Furthermore, the power control unit controls the network terminal device under test to perform power-on and power-off operations at preset frequencies and time intervals using continuous power-on and power-off commands, including... The test console sends a test end command to the test unit and the unit under test according to the test script. The test unit and the unit under test then end the test and return the test results to the test console. After all test cases have been executed, the test console sends a power-down command to the power management unit. The power management unit stops outputting according to the power-down command, performs a power-down operation on the unit under test, and sends a response message to the test console.

[0017] Furthermore, the power control unit controls the network terminal device under test to perform power-on and power-off operations at preset frequencies and time intervals using continuous power-on and power-off commands, including... The continuous power-on and power-off commands are the device power-on commands, continuous device power-on / off commands, and device power-off commands sent by the test console to the power management unit; According to the power control requirements of the network terminal device under test, the requirements include command type, first output voltage, number of power-on and power-off cycles of the first output, power-on and power-off time interval of the first output, and ... the nth output voltage, number of power-on and power-off cycles of the nth output, power-on and power-off time interval of the nth output, and whether a response is required, where n is the number of power control output channels; The test console and power management unit use Ethernet messages for command transmission. The command transmission format includes a command type (1 byte long), output voltage (2 bytes long), power-on / off count (2 bytes long), power-on / off time interval (2 bytes long), and whether a response and data reporting message are required (1 byte long). For example, to transmit a command message, the request message and parameter definitions are shown in Table 1: command type (1 byte long); output voltage (2 bytes long); power-on / off count (2 bytes long); power-on / off time interval (2 bytes long); whether a response and data reporting message are required (1 byte long). The data format is shown in... Figure 3 .

[0018] In one embodiment, S104 includes generating a test report of power-on and power-off commands based on feedback information, and the test console generates a test report based on the test results fed back by the test unit and the unit under test.

[0019] In some or all of the above embodiments, the control command design and response message design are specifically as follows: (1) Control command design, wherein the request message is the device power-on command, device continuous power-on / off command and device power-off command sent by the test console to the power management unit.

[0020] Based on power control requirements, the control command parameters include command type, first-channel output voltage, number of power-on / off cycles for the first channel, power-on / off interval for the first channel, ..., nth-channel output voltage, nth-channel power-on / off cycles, nth-channel power-on / off interval, and whether a response is required. Here, n represents the number of power output channels controlled by the power supply.

[0021] The device uses message parameters as Ethernet payload for transmitting command messages. The request message and parameter definitions are shown in Table 1: Command type (1 byte long); Output voltage (2 bytes long); Number of power-on / off cycles (2 bytes long); Power-on / off time interval (2 bytes long); Whether an acknowledgment and data reporting message are required (1 byte long). Data format is as follows: Figure 3 .
