设计和研制了一种适用于大专院校示范教学实验的虚拟仪器。该虚拟仪器以GPS接收模块输出的1PPS(秒脉冲)信号为基准,测量无源石英晶体振荡器频率,同时利用GPS信号实现了仪器的时间同步与测距功能。从硬件和软件两方面描述了该虚拟仪器的构成及设计方法,主要介绍和讨论基于GPS和虚拟仪器技术实现多功能测量的途径。
Abstract：A virtual instrument is designed and implemented,which is applicable to the demonstration experiments for universities.This vitrual instrument can measure the frequency of passive quartz crystal oscillator using the output 1PPS signal of GPS module as the time standard and accomplish the time synchronization and distance measurement using the GPS signals.The composition and design of the virtual instrument in both hardware and software are described.The way to realize the multifunction measurement based on the virtual instrument technique and GPS is mainly introduced and discussed.
