Abstract

The present invention relates to a FC-AE-1553 protocol conversion multi-protocol multi-channel data recording system, which includes: an ARM processor for receiving FC-AE-1553B data, CAN bus data, and 1553B data; FPGA chip A integrates FC ‑AE‑1553 controller IP core, FPGA chip B integrates CAN and 1553B controller IP core; FPGA chip A is connected to optical transceiver, FPGA chip B is connected to CAN transceiver and 1553B transceiver; ARM processor waits for data generation on the communication bus , when receiving the data, identify the source of the data, after confirming the source of the data, read the data, keep the data segment in the CAN protocol, the content of the FC‑AE‑1553 and 1553B commands, and discard the rest of the data, and then FC‑AE‑1553 and 1553B The time information of AE-1553 is read out, the time information is combined with the received and processed control data, and special symbols are filled in to distinguish the time information and data, and stored in the NVMe electronic disk.

Description

technical field [0001] The invention relates to a data communication technology, in particular to an FC-AE-1553 protocol conversion multi-protocol multi-channel data recording system. Background technique [0002] At present, FC-AE is widely used in the field of aerospace and industrial control. With the higher and higher requirements for communication speed, more and more applications of optical fiber communication, high-speed real-time control FC-AE-1553 came into being Health, FC-AE-1553 inherits the advantages of MIL-STD-1553B, has the characteristics of high reliability, high real-time performance, high fault tolerance, etc., and increases the communication rate to 1 / 2 / 4 / 8Gbps. In the process of remote control, because the current cost of FC-AE-1553 is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a FC-AE-1553 protocol conversion multi-protocol multi-channel data recording system, which is used to solve the abo...
