摘要
为满足容错计算机联锁系统与现场设备之间通信的传输速率和可靠性的要求,研制了一种基于CPCI总线的新型智能双通道CAN通信卡,给出了Windows平台下具有内存及I/O读写、中断处理驱动程序的设计方法。现场运行结果表明,该CPCI-CAN通信卡及其驱动程序工作正常,较好的满足了容错计算机联锁系统对通信的要求,应用前景广泛。
According to requirements of speed and reliability in communication between Fault-tolerant computer interlocking systems and field devices,a new smart double-channel CAN communication card is designed.The paper describes how to develop the WDM driver which features Memory and I/O read and write as well as interrupt handling under the Windows platform in detail.Results of field operations indicate that CPCI-CAN card and its driver can operate normally and stably and meet communication requirements in the Fault-tolerant computer interlocking systems.At the same time？,The application prospect？is aboard.
