A bus type fc-ae-1553 network system and data sending and collecting method

Abstract

The invention relates to a bus type FC-AE-1553 network system and a data sending and collecting method based on the network system. The bus-type FC-AE-1553 network system includes a network controller, a network terminal, a bus-type optical fiber network, an optical splitter and a network matching device. The interface types of the bus-type optical fiber network include network ordinary nodes and network matching nodes; the network controller is connected to the network ordinary nodes of the bus-type optical fiber network, and is used to manage the communication process of the entire bus-type FC-AE-1553 network system; the network terminal connection It is used as an ordinary network node in the bus-type optical fiber network, used to passively receive the instructions of the network controller in the FC-AE-1553 network system, and complete the operation according to the instructions of the network controller; the optical splitter is used to realize the branching of optical fiber signals; network matching The device is used for terminal matching of the bus-type optical fiber network to realize sequence forwarding. The data sending and collecting process of the present invention realizes the data exchange between the network controller and the network terminal through the network matching terminal.

Description

technical field [0001] The invention relates to the technical field of the topology structure of the bus type FC-AE-1553 network, in particular to a bus type FC-AE-1553 network system and data sending and data collection methods. Background technique [0002] The FC-AE-1553 bus is an emerging high-reliability, high-speed optical fiber bus. Its protocol is formulated by the American National Standards Institute (ANSI) and defines the mapping from the MIL-STD-1553B protocol to the Fiber Channel (FC) high-level protocol. It provides protocol support for the development of fiber optic 1553 bus controller. Like the traditional 1553B bus, FC-AE-1553 defines a command / response bus standard, but has greatly improved bus capacity, transmission rate, and reliability. At the same time, the FC-AE-1553 bus adopts optical fiber transmission medium and network topology, which has strong anti-interference ability and expansion ability, and is very suitable for electronic system networking ...
