摘要
介绍了面向CAN总线接口卡的PCI接入技术,给出了该接口卡的硬件设计以及DOS下驱动程序开发的具体思路和实现方法。与Windows系统下的驱动相比,在DOS下开发的驱动程序,使该卡通信速度和实时性有了大幅度的提高,从而能够更好地满足工控系统的实时性需求。实际应用结果表明:该卡在DOS下运行稳定,实时性强,可靠性高。
Introduced the CAN-PCI bus interface card access technology, and described the design idea and realizntion method for its hardware and the driver program in DOS. The driver developed in DOS, compared to which in Windows, guarantees a dramatic improvement over communication speed and timing accuracy of the card. Hence, it better meets the real-time performance of the industrial control system demands. Application results show that the card is stability, real,time and high reliability.
