基于TMS570高安全通用总线接口模块设计

Design of high security universal bus interface module based on TMS570

为了提高航电系统第三方子系统的扩展能力,文章基于TMS570芯片设计了一种高安全通用总线接口模块。该模块符合VITA48的3U标准尺寸,集成了RS422、RS232、ARINC429、CAN、FlexRay以及ETH总线接口。该模块具有高集成度、高综合化、高安全性、小型化等优点,应用于通用飞机航电系统,可以很好的满足通用飞机多种多样的信号接口种类和数量需求。

In order to improve the expansioncapability of the third-part subsystem of avionics system,this paper designs a high security general-purpose interface bus module based on TMS570 chip.The module meets the 3U standard size of VITA48 and integrates RS422,RS232,ARINC429,CAN,FlexRay and ETH Bus interfaces.This module has the advantages of high sythesization,high integration,high security,miniaturization and so on.It can be applied to the avionics system of general aircraft,and can well meet the requirements of various types of signal interfaces of general aircraft.
