Active high-speed coaxial FC-AE-1553 bus type network

Abstract

The invention discloses an active high-speed coaxial FC-AE-1553 bus type network, and relates to the field of bus type networks. The bus type network comprises a network node and a high-speed active coupler; the network node at least comprises a power supply module, a protocol chip and at least one isolation transformer; the protocol chip can be configured to be in a network controller mode and / or a network terminal mode; the high-speed active coupler at least comprises a power supply module, at least one isolation transformer, an HMC744 module and an MAX3841 module. The network node and the high-speed active couplers are connected through coaxial cables, and the high-speed active couplers are connected through coaxial cables.

Description

technical field [0001] The disclosure relates to the field of bus network, in particular to an active high-speed coaxial FC-AE-1553 bus network. Background technique [0002] In the prior art, the traditional military control bus adopts MIL-STD-1553B bus, and its network topology is a passive coaxial bus network with a transmission rate of up to 1Mbps. The transmission medium adopts coaxial cables, and its network composition is as follows: figure 1 As shown, including the coupler, bus controller (BC) and remote terminal (RT), all network nodes are connected through the coupler; [0003] However, the transmission rate of the MIL-STD-1553B bus is low. In order to solve the problem of low transmission rate, the control bus adopts FC-AE-1553 bus, and the transmission medium adopts optical fiber. The network topology is as follows: figure 2 As shown, including network controller (hereinafter referred to as NC node, Network Controller), network terminal (hereinafter referred to...
