摘　　要：介绍了OPC技术产生的工作过程、工作原理及相关理论。针对LabVIEW软件平台,提出三种通讯的途经:通过Active自动化接口实现对OPC服务器的访问;通过DataSocket技术实现对OPC服务器的访问;通过DSC模块实现对OPC服务器的访问。分析了每种访问途经的特点和适用范围,最后以实际运用验证其有利于虚拟仪器系统的开发、可维护性和扩展性。The working process and working principal and relevant theory were introduced. To LabVIEW software development platform, three eontaet solutions were put forward： to visit OPC server by Aetive automation interfaee; to visit OPC server through DataSoeket technology; to visit OPC server through DSC module. The character and suitable range of three method were analyzed. The praetieal result shows that it is benefit to visual instrument system development, maintainability and expansibility.
