摘要
针对机载设备地面检测中ARINC429总线数据通信这一关键技术,设计了一种基于十六位单片机80C196的ARINC429总线收发系统;设计中严格依据ARINC429数字信息传输规范,采用通用ARINC429专用器件HS3282/HS3182构成数据收发核心单元,通过对可编程逻辑器件编程实现系统的逻辑设计,并采用硬件上奇偶校验和软件循环冗余校验实现系统智能纠错。
A novel ARINC429 bus transmit- receive installation based on 16 bits single-chip microcomputer 80C196 is designed, which aims at the key technology of ARINC429 bus data communication used in airborne device ground test. It strictly executes ARINC29 digital information transmission specification, adopts universal ARINC429 special component HS3282/HS3182 to form a data transmit-receive core unit. System logical design is achieved by programming with PLC. Simultaneously, use hardware odd-even check and software circle redundancy check to implement system intelligent correction.
