Abstract: Since there’s a lack of unflexibility of the correspondence interface for the conventional data acquisition system, a high speed data acquisition system is designed based on LabWindows/CVI. The CY7C68013A chip of Cypress Corporation FX2LP serial is used as the main chip and USB2.0 interface chip. LabWindows/CVI is chosen to build the software platform, and Dynamic Linking Library(DLL) is used to design communication software for the PC and data acquisition system. Results prove that the system can absolutely fulfill the design and use request.

Key words: data acquisition, Dynamic Linking Library(DLL), software platform

摘要： 针对传统数据采集系统通信接口缺乏灵活性的问题，提出一种基于LabWindows/CVI的高速数据采集系统。以Cypress公司FX2LP系列的CY7C68013A芯片作为通信和主控芯片，选择LabWindows/CVI语言搭建数据采集系统的软件平台，采用调用动态链接库方法设计上位机和数据采集系统的通信软件。结果证明，该数据采集系统完全满足设计和使用需求。
