摘要
VPI接口的工程绘图仪在石油物探与测井资料数据处理中使用广泛,但对于PC机而言属非标准接口设备,因此无法在微机Windows操作系统下联机驱动。基于微机并行接口,通过设计一外置VPI接口转换器,配合驱动程序,实现了在多种处理平台下用Windows 2000/XP驱动VPI接口的工程绘图仪。VPI接口转换器具有硬件结构简单、输出快捷、经济实用等优点。
The plotter with a VPI interface is widely used in seismetic data processing and logging data processing.But it cannot be drived under windows operation system.According to PC parallel interface,we design an outside VPI interface converter and driving software,with them we can realize to drive various plotter with the VPI interface under Windows 2000/XP on the basis of processing platform.The VIP interface converter has the advantages of simple structure,quick output and economy.
