摘要
为提高多路ARINC429总线数据接收和发送的实时性,提出一种基于POWERPC硬件和嵌入式实时VxWorks操作系统的ARINC429总线接口解决方案,将ARINC429协议芯片映射到地址空间,简化了传统驱动开发中设备向I/O系统注册和创建的过程,利用VxWorks实时操作系统的多任务特点,实现多通道ARINC429通讯并行处理,有效提高了系统的实时处理能力;通过在直升机完好性与使用监测系统中应用表明,该解决方案实时性好、可靠性高,满足系统要求,具有很好的推广应用前景。
To improve the real--time communication of multi--channels ARINC429 bus acquisitions and transmissions, a kind of new ARINC429 interface card based on POWERPC and the embedded VxWorks real--time operating system is put forward. Mapping ARINC429 bus protocol chips to the memory address space, it simplifies traditional development of driver. Making full use of the VxWorks which is the real--time multi--task operating system, multi --channels ARINC429 bus acquisitions and transmissions are accomplished. Its processing rate is higher, it can improve the performance of this 429 interface card. This system can successfully run in practical application, with good promotion prospects.
