一种新型数据采集卡的研制

Research of a New Data Acquisition Card

介绍了一种新型数据采集卡。硬件设计基于复杂可编程逻辑器件 (CPLD) ,体积小 ,工作可靠 ,控制简单 ;软件设计基于COM技术规范 ,可根据用户需要进行动态链接 ,实现多种复杂的测控功能 ,极大地提高了应用的灵活性。

A new type of data acquisition card is introduced. The design of hardware is based on a CPLD(Complex Programmable Logic Device),so the card possesses the advantages of small volume,reliability and simply control.The design of software is based on the technological standard of COM(Component Object Model),which can be dynamically linked and realizes many functions of measurement and control,so the flexibility of application is greatly strengthened.
