Description

(1) Technical field:

[0001] The invention relates to the test of a wideband avionics bus, and provides an evaluation platform for detecting its working performance for the bus system, specifically, refers to a wideband avionics bus testing device and its operation method, belonging to the avionics bus Test device technical field. (two) background technology:

[0002] With the development of avionics technology, avionics bus technology has undergone generational evolution from discrete, combined, and even integrated. The broadband avionics bus system is an integrated information system used for information exchange and resource sharing between avionics subsystems. It is a crucial "central nerve" in the avionics system. Compared with vertical and joint avionics bus technologies, it has higher throughput, lower message delay and higher reliability. Therefore, how to use a reasonable method to test and verify the basic performance and functions of the broadband avionics bus sy...
