Implementation of a High-speed Data Collection System Based on Delphi 7.0

In industry control field,Analog-To-Digital Converter chip is often used for low-speed analogical data collection.But the common Analog-To-Digital Converter chip can not meet the requirements of high-speed vary analogical signal.It gives a high-speed data collection system based on PCI-1716L card as the interface by using Delphi 7.0 language.It realizes the high-speed analogical data collection by the method of software polling.
