Embodiment 1
[0031] Such as figure 1 As shown, the main function test of the AFDX network selection module is the communication selection function test.
[0032] Aiming at the test requirements of the communication selection function of the AFDX network selection module, the present invention proposes a test method using two AFDX network selection modules cascaded to realize the communication selection function test of the AFDX network selection module, which is easy to implement, simple to operate, and easy to test. Features of high efficiency.
[0033] In practical applications, the AFDX network selection module includes a first switch port, a second switch port, a first end system master port, a first end system slave port, a second end system master port and a second end system slave port. The AFDX data transceiver module includes a first test port and a second test port. Wherein, the first switch port is port R5, the second switch port is port R6, the primary port of the first end s...
Embodiment 2
[0043] The present invention will be further described below in conjunction with accompanying drawing:
[0044] Such as figure 1 As shown, the implementation steps of a test method for an AFDX network selection module are as follows:
[0045] (1) Press the ports of two AFDX network selection modules to figure 1 Connect as shown, wherein, the unit under test 1 is the AFDX network selection module 1, and the unit under test 2 is the AFDX network selection module 2;
[0046] (2) Set the channel selection switch K1 of the unit under test 1 to a high level, and at this time, the port R5 and the R1 channel of the AFDX network selection module 1 are connected, and the port R6 and the R2 channel are connected;
[0047] (3) Set the channel selection switch K2 of the unit under test to be high level, and now the port R5 and the R1 channel of the AFDX network selection module 2 are connected, and the port R6 and the R2 channel are connected;
[0048] (4) Set the AFDX data transmission...

Abstract
The invention belongs to airborne network testing technology, and relates to a testing method for the communication selection function of an AFDX network selection module. Aiming at the communication selection function of the AFDX network selection module, the invention proposes a test method using two AFDX network selection modules cascaded, which solves the problem of rapid testing of the communication selection function of the AFDX network selection module. The solution of the present invention has a small number of test cables, can test two AFDX network selection modules at the same time, does not need to replace the test cables during the test process, and has the characteristics of easy implementation, simple operation and high test efficiency.
Description
technical field [0001] The invention is used in the field of airborne network testing and relates to a testing method for the communication selection function of an AFDX network selection module. Background technique [0002] Avionics full-duplex switched Ethernet (AFDX) is a real-time, deterministic full-duplex switched Ethernet, which is currently internationally recognized as the mainstream airborne network of transport aircraft. In the airborne network, in order to prevent the failure of a single AFDX end system module from causing the failure of a node function, some important AFDX devices use two AFDX end systems as backups for each other. The AFDX network selection module can provide network selection for the AFDX network communication between the mutually backup AFDX end system modules and other devices according to the state information of channel selection. [0003] The AFDX network selection module has six external AFDX network interfaces. The original test metho...
