基于星弹载嵌入式系统的CAN总线驱动技术研究

摘要

In light of the superiority of CAN bus to control peripheral equipment, the design and implementation of the CAN bus driver software based on SJA1000 had been studied. By analyzing the relationship between the satelliteborne and missileborne embedded system hierarchical structure and device drivers, the design concept of CAN bus driver through the operating system extension modules was given. Combining with the related specific test application, the developed CAN bus driver software were tested with ZLG CAN Test software. Confirmed that the CAN-bus driver software could meet the reliability and real-time application requirements.%针对CAN总线在控制外围设备方面的优势,对基于SJA1000的CAN总线驱动软件的设计与实现展开研究；通过分析星弹载嵌入式系统层次结构和设备驱动的调用关系,提出了通过操作系统的扩展模块调用CAN总线驱动程序的设计理念；结合相关具体应用设计测试用例,并通过ZLGCANTest软件对所研发的CAN总线驱动软件进行了测试；证实所开发的CAN总线驱动软件在可靠性和实时性方面都能满足应用要求.
