Embodiment Construction

[0037] For the existing problems, the present invention provides a vehicle electrical system terminal communication, data communication based on the power line, thereby reducing the complexity of the cable network.

[0038] The communication terminal according to the present invention, comprising a master node and a plurality of terminals, selecting a terminal node of the master electronic device mounted in an aircraft electronic system from a terminal node, is mounted on the electronic device from the rest of the terminal node, the master node and slave node terminal end can be achieved automatic network, forming a multi-stage tree structure associated to the master node terminal as the center, all connected to the same terminal from a node in a network 28V supply. Each forwarding information transmitted from the terminal node and the master node through a terminal 28V DC power lines. As each slave node can relay communication terminal contacts when the terminal is located from t...
