Abstract: It is a tendency to build quick-response system for the future aerospace technology, and module synthetical electrical interconnection technology is the key. In this paper, module synthetical electrical interconnection technology based on VPX, which could achieve high-speed and rapid electrical connection between different functional modules without cable, is studied. The backplane use the topological structure of single star interconnection. Functional modules are packaged uniformly and are controlled centrally by exchange board using identification technology, and then functional modules could be exchanged indistinguishably. Electrical source management uses digitized power distribution technology to realize health managements for functional modules such as in-position check, power-on in right order, overcurrent protection, and so on.
