基于CPLD与DEI1016的ARINC429总线板设计

Design of ARINC429 Bus Board Based on CPLD and DEI1016

以机载设备间数据信息通信为应用背景,提出了一种基于CPLD和DEI1016的ARINC429总线通信设计方案.基于ARINC429总线的数据传输规范,给出了429总线通信板卡的硬件设计和软件设计,分析了利用CPLD和DEI1016完成的429接收数据中断处理电路和发送数据查询电路,实现了429总线通信板卡的全双工通信方式.通过验证,使用这种方案实现的ARINC429总线通信板卡满足系统要求.

In this paper,a sort design scheme of ARINC429 bus communication based on CPLD and DEI1016 is proposed,taking the data communication between the airborne equipment as the application back-ground.In terms of ARINC429 bus data transmission specification,the design of hardware and software of 429 bus communication board card is presented,the interrupt processing circuit for the received data and inquiry circuit for transmitted data of the 429 board implemented by using the CPLD and DEI1016 are analyzed,realizing the full duplex communication of 429 bus communication board card.By experiments,it is verified that the ARINC429 bus communication board card implemented by taking the proposed scheme can meet the system re-quirements.
