[0065] S1. Based on the interface type and quantity of the avionics equipment under test, in the graphical configuration interface (refer to...) Figure 4 Add interface configuration information to the interface configuration area shown. When the interface data type is A429, you need to configure the A429 board number, A429 board channel number, transmit / receive rate, parity check, and other information. When the interface data type is discrete, you need to configure the specific values ​​of high and low levels of the discrete board. When the interface data type is analog, you need to configure the sampling rate and sampling quantization bits of the analog board's AD and DA conversion.

[0066] S2. For A429 bus type interfaces, the A429 data format for sending or receiving needs to be set in the interface configuration area. This includes the following configuration information: A429 data content (4 bytes), including Label number (1-8 bits) and data bits (9-31 bits), with parity bits (32 bits) automatically calculated and filled according to the calculation framework; A429 data transmission count; and A429 data transmission cycle.

[0067] S3.

Figure 3 As shown. The test host is connected to the avionics equipment under test via a cable. The test frame controls the A429 board, discrete circuit board, and analog circuit board to send test information to the avionics equipment through the driver.

[0079] When the test framework receives control commands from the local application or remote control host via Ethernet, it can also send test information to the avionics equipment and feed back the output results of the avionics equipment via Ethernet. In the above scenario, the test device of this embodiment can serve as the basic carrier for automated test applications, receiving and sending data from various bus interfaces and verifying the correctness of the output results of the avionics equipment.

[0080] The data link to the specified interface of the avionics device under test (A429) can be dynamically configured graphically. The data link can be configured as ARINC 429 (A429) bus type, discrete type, or analog type. For A429 bus type links, the content format of the A429 data transmitted and received on that link can be configured graphically to quickly set up A429 data and send test data to the A429 device. This graphical interface link and A429 data content format configuration information can be stored as a configuration file for reuse in testing other A429 devices, significantly reducing repetitive work.

[0081] Furthermore, embodiments of the present invention also provide remote control interfaces for other applications to send control commands via Ethernet, providing a foundation for automated testing of avionics equipment.
