瞬态信号集中式测量系统接口的 PC 机驱动设计
Design of PC driver for the interface of centralized measurement system of transient signal
摘要
Abstract
In order to realize the real-time transmission of the transient signal centralized measurement system,a centralized measurement system based on the PCIe bus is established.The design of the PCIe bus interface of the transient signal centralized measurement system consists of the design of the PCIe slave device and the PC driver.The design of the PC driver is only researched in the paper.NI-VISA and LabWindows development environment are used to design the PC driver program of PCIe bus.First of all,NI-VISA Driver Wizard is used to configure PCIe equipment informations and inter-rupt detection registers to generate an inf driver configuration file.Then,the PCIe bus is initialized and the DMA data transmission is designed with the LabWindows.Finally,the PC driver of the PCIe bus is tested.Experimental results indicate that the PCIe bus driver transmission rate can reach 300 MB/s with the NI-VISA and LabWindows development environment.The PCIe bus driver designed by NI-VISA and LabWindows development environment,not only meets the data transmission require-ments of centralized measurement system for transient signal,but also reduces the development diffi-culty of the PCIe bus and shortens the development cycle.关键词
