Abstract

The invention discloses a control switch module based on VPX bus. By splitting the control switch module into a main control board and a switch board, the contradiction between too many interfaces and limited volume of the control switch module is solved; according to actual task requirements and resources In terms of use, multiple control switching modules with the same configuration can be used to work at the same time, and perform hot backup to achieve dual redundancy functions to ensure the reliability of the entire system; the invention also uses board-to-board high-speed connectors to complete the main control board and the switching module. The interaction of data and commands between boards effectively improves the flexibility, versatility and reliability of the control switch module.

Description

technical field [0001] The invention belongs to the technical field of embedded signal processing, and more specifically relates to a control switching module based on a VPX bus. Background technique [0002] The future information system will develop towards the trend of air-space-ground integration and coordination under the three-dimensional support of the five-dimensional integration of landing, sea, air, space, and electricity. The integrated information processing platform is a general-purpose airborne avionics system for air-space-ground integrated aircraft. Its application extends from the traditional local aviation and aerospace areas to the global full space range composed of aviation areas, adjacent space, and orbital space, and requires Support hardware and software reconfiguration to achieve multi-functional multi-tasking such as reconnaissance, jamming, detection, communication, and attack. [0003] The evolution of the future information system puts forward h...
