Non-transparent bridge system between fc-ae-1553 bus and can bus

Abstract

The present invention relates to a non-transparent bridging system between FC-AE-1553 bus and CAN bus, which includes: NC terminal, NT terminal and controlled equipment; NC terminal is composed of controller and FC-AE-1553 module; NT equipment includes ARM processor, FPGA, CAN transceiver module, network transformer and optical fiber communication module; ARM processor and FPGA use PCIe for high-speed data intercommunication, FPGA embedded IP core form realizes CAN communication interface, running time through FC‑AE‑1553 protocol for time synchronization. The present invention bridges the low-speed short-distance real-time control bus with the high-speed bus under certain circumstances, which can satisfy the long-distance transmission of control information. The application of the electronic system in the high-speed communication of the bus is remote control and the application of high-speed and low-speed bus conversion. It can meet the application of the electronic system in the high-speed bus communication and remote control, and the application of high-speed and low-speed bus conversion.

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...

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.
