摘要:

为实现指令的可靠接收和远距离、大容量数据的高速回收,结合1553B总线的实时性、高可靠性和以太网传输的速度快、距离远等优点,设计了基于1553B总线和以太网的接口方案;介绍了BU-65170作为RT端与BC端通信的硬件设计、初始化配置及消息的接收,阐述了W5300与远端上位机通讯的硬件设计及UDP传输,并针对以太网采用快速UDP传输方式的不可靠性,从硬件设计和逻辑实现进行了可靠性优化,经过试验验证,采用20 m屏蔽双绞线,以7 MB/s速度传输数据,未出现丢数和误码现象,已成功应用在工程实践中。

Abstract:

To achieve the reliable receiving of the command and the high-speed access of large capacity of data, combined with the real time and high reliability of 1553b bus and the high speed and long distance of Ethernet transmission, designed a interface scheme based on 1553b bus and Ethernet protocol. Introduced in detail the hardware design, pattern configuration and implementation of receiving message of BU - 65170 as RT communicating with BC, and expounded hardware design and UDP transfer of the communication between W5300 and terminal computer. The reliability is optimized via hardware design and logical realization to overcome the unreliability of the rapid UDP transmission. Through the test, with 20m shielded twisted-pair cable, 7 MB/s data transmission speed, no data lost and error phenomenon. It has been successfully applied in engineering practice.
