中文摘要:
      基于LabVIEW平台的信号实时采集与处理系统,相对于传统的基于Visual C++或VxWorks的系统,具有软件开发和修改快捷、可快速实现数据可视化、与通用平台或设备接口方便等优点,使科研人员能够将主要精力集中于实验而非编程.介绍了一种基于LabVIEW平台的信号实时采集与处理系统.首先介绍了该系统的硬件组成和软件设计方法,之后详细介绍了将不同厂商的硬件板卡集成到LabVIEW平台上,并由LabVIEW统一控制的方法——生成动态链接库.该系统已成功应用于某型水声装备的效能评估试验中.
英文摘要:
      Compared with traditional systems which are based on Visual C++ or VxWorks, the real-time signal acquisition and processing system based on the platform of LabVIEW has many advantages in easy developing and modifying software, quick realizing data visualization and easy connecting with general-purpose platforms or equipments. This system can make the scientific researchers focus their energies on experiments rather than programming. A practical real-time signal acquisition and processing system based on the platform of LabVIEW is introduced in this paper. The hardware constitution and the software designing method about this system are firstly described, and then the method to generate a dynamic link library (DLL) is explained, which is used to integrate hardware cards from different manufacturers onto LabVIEW. This system has been successfully used in the experiment to evaluate the effectiveness of a certain kind of underwater acoustic equipment.
