摘　　要：虚拟仪器在测试领域的应用极大地提高了测试的灵活性和扩展性。为了提高拖曳水池试验效率和加强采集系统功能,结合虚拟仪器技术和LabVIEW开发环境设计并实现了试验数据采集系统。系统中成功运用三层式结构组织系统程序,合理地优化了系统结构。功能框架模式、智能仪器识别系统、基于心跳消息和多线程的通讯方式,数据实时监控技术以及基于Java存储过程的数据存储,这一系列技术的设计和创新有效地提高了运行效率、系统稳定性、操作性、灵活性以及可扩展性。XML配置文件也提供了一种方便、灵活系统信息配置方式。Virtual instrumentation being introduced into measurement field has greatly enhanced the flexibility and expansibility of measurement. To improve efficiency of test in towing tank and to enhance reliability of system, a data acquisition system for test based on virtual instrument and LabVIEW is designed and realized. The three-tiered structure used in constructing system, frame optimized suitably. Many skills and innovations, which contain function structure model, intelligentized instrument recognition, communication based on heart-beat checking and multi-threading, real-time watch for test and data store with java procedure, improve efficiency, reliability, operability and extensibility. Config with XML also provide a convenient and flexible approach to configure.
