An FC-AE-1553 bus and CAN bus non-transparent bridging system

Abstract

The invention relates to an FC-AE-1553 bus and CAN bus non-transparent bridging system comprising an NC end, an NT end and controlled equipment, NC end consists of a controller and FC-AE-1553 module;the NT device comprises an ARM processor, an FPGA, a CAN transceiver module, a network transformer and an optical fiber communication module. The ARM processor and the FPGA are in high-speed data intercommunication through PCIe, a CAN communication interface is achieved in the mode that an IP core is embedded in the FPGA, and the operation time performs time synchronization through an FC-AE-1553 time checking protocol. The low-speed short-distance real-time control bus and the high-speed bus are bridged under specific conditions, long-distance transmission of control information can be met, and an electronic system is applied to bus high-speed communication in remote control and application to mutual conversion of the high-speed bus and the low-speed bus. The application of an electronic system in remote control of bus high-speed communication and the application of mutual conversion of high-speed and low-speed buses can be met.

Description

technical field [0001] The invention relates to a bus communication technology, in particular to a non-transparent bridging system between FC-AE-1553 bus and CAN bus. Background technique [0002] In complex systems such as industrial fields, automotive fields, and medical fields, a large number of electronic buses are used to transmit data and control signals. For example, the CAN bus, in the SAE J1939 protocol, defines the application of important information such as vehicle speed, speed, EPS, seat belts, serious engine failures, and general engine failures. The CAN bus communication distance can reach up to 10KM (the communication rate is not higher than 5Kbps) and the speed can reach 1Mbps (the communication distance is not higher than 40M). CAN bus is also used in many industrial controls, but because of its protocol, CAN bus has a maximum transmission distance of no more than 40M at an operating frequency of 1Mbps in an ideal environment. The communication distance is...

AI Technical Summary

Problems solved by technology

CAN bus is also used in many industrial controls, but because of its protocol, CAN bus has a maximum transmission distance of no more than 40M at an operating frequency of 1Mbps in an ideal environment. The communication distance is short, and it is difficult for users to use it remotely.

The common high-speed communication bus has a large amount of data, and the transmission distance depends on the transmission medium. The longest transmission distance can even reach 5 kilometers, but the real-time control ability is not strong.
