| 摘 要： | 目前的虚拟仪器系统大多采用美国NI公司LabView平台，采用PCI总线结构的数据采集卡进行数据采集。主从式虚拟仪器技术在软件和硬件都摆脱了LabView的框套。该技术利用基于单片机的数据采集器进行A／D转换和预处理，通过RS－232串行口与主机进行信息传送，插拔方便。主机通过数据处理软件对数据进行处理和分析。用户可以通过主机的软件界面对单片机（从机）进行控制，使之能按照不同的要求对信号进行数据采集和处理。

| Abstract: | At present most Vitual Instrument Systems are developed based on LabView produced by NI and In those systems Data-Acquisition-Cards of NI are used.Introduces a virtual instrument system with a master-slave structure.The hardware and software of this system break away from the restrict of NI developing enviorment.This system uses a Data-Sampler based on microcontroller which communicate with a PC through RS-232 serial port.The data sampled by the Data-Sampler is processed by the data processing software installed on the PC.Users can control the Data-Sampler through the virtual control panel on the PC. |
