摘要
设计了一套试验平台用的信号检测系统,介绍了其硬件结构和软件模型,给出了测试程序框图和显示界面。该系统硬件结构包含模拟信号调理模块、数字信号光电隔离模块及其数据采集板卡。系统软件采用LabVIEW编程技术,实现了对信号的采样、处理、显示和存储,介绍了在LabVIEW环境下对Access数据库OLE字段类型的读取与写入。经测试,其功能稳定、误差小,完全满足试验平台的功能要求。
A set of test platform used in signal detection system is designed,its hardware and software model are introduced,and the test program block diagram and display interface are also given.The system hardware consists of analog signal adjusting modules,digital signal photoelectric isolation modules and data acquisition boards.System software using LabVIEW programming technology realizes signal sampling,processing,display and storage,and the way to read and write OLE field of Access database in the LabVIEW environment is introduced.This system is proved to be stable and minor error,and fully meets the functional requirements of the test platform.
