摘要/Abstract

摘要： 介绍了一种基于 ISA 总线的高速数据采集系统的硬件及软件设计该系统采用异步启动4块 ADS7810模数转换器的方法来相对缩短 AD 转换时间从而在 ISA 总线上实现了频率2．6☞MHz 的高速采集速率．用便于移植的虚拟设备驱动程序（VxD）读取采集数据并由Windows 应用程序显示和处理．实验表明该系统的性能指标满足高压脉冲电场食品杀菌装置的电压采集要求．

关键词: 高速数据采集, ISA 总线, 虚拟设备驱动程序

Abstract: The hardware and software design of a high-speed data sampling system based on ISA bus was introduced．
In this systemfour pieces of ADS7810AD converters are started in turn at a certain interval to shorten the AD con-
verting time comparativelythus obtaining a high data sampling speed of2．6☞MHz in the system on ISA bus．Virtual
Device Driver （VxD）which is easy to transplant to other applied situationsis adopted to read the sampled data．The
sampled data are displayed and processed through a Windows application．Experiment results show that the perfor-
mances of the system can meet the requirements of the food sterilization device with high-voltage pulsed electric field．

Key words: high-speed data sampling, ISA bus, virtual device driver
