【摘要】 基于LabWindows/CVI软件开发平台,设计了高速数据采集系统.该设计采用线程安全队列开辟的缓存实现线程的同步与通信,以动态链接库解决USB板卡与应用软件之间的通信,从而实现数据的波形分析、频谱分析和频率计数.实际应用表明,该系统运行稳定.更多还原

【Abstract】 A high-speed data acquisition system is designed which based on LabWindows/CVI software development platform.This system is designed for synchronization and communciation of thread by using thread safe queues.DLL is used to solve the communciation between USB card and application software,and with these effort wave analysis/frequency analysis and frequency counting are realized.The practical applications show the stability in the system running.更多还原
