摘　　要：利用NI公司的PCI数据采集卡建立虚拟仪器数据采集系统,在自动测试领域得到了广泛的应用。但在一些情况下,工程人员希望使用现有的或性价比高的第三方数据采集卡建立系统,同时又可以充分利用LabWindows/CVI强大的测控功能。本文以中泰PCI-8333数据采集卡为例,详细介绍了如何利用动态链接库机制实现LabWindows/CVI与第三方PCI数据采集卡的通信,建立温室环境参数数据采集系统。通过调用DLL实现Labwindows/CVI对外部模块的连接,构建所需的测控系统,保持各模块的独立性,便于程序的二次开发应用。The data acquisition systems of virtual instrumentation using the NI data acquisition cards are being in wide use. In some cases, the engineers are trying their best to use other cheaper cards, and take advantage of LabWindows/ CVI powerful function library to build the DAQ system. The present study is to adopt ZhongTai PCI-8333 DAQ card with the purpose of controlling the greenhouse environmental parameters test system. Communication between LabWindows/CVI and the third part DAQ card is connected by dynamic link library. Communicating between LabWindows/CVI and exterior module is connected by DLL, and the measure and control systems can guarantee the independence of each module for the further development.
