摘　　要：采用合理的硬件电路和先进的软件算法,将通信技术中时分复用技术引入多路信号采集虚拟仪器系统,多路信号经同一通道传送到PC机数据采集卡中,利用计算机强大的软硬件功能将采集的数据,进行分析和处理后,通过显示设备输出,实现模拟信号的测试。这种方法克服了多通道同时采集时占用硬件资源大、浪费严重等缺点。有效节约了系统资源,使复杂的控制系统变的简单,易于实现柔性生产。The Time dispart multipath technology of the communication system is introduced into multipath virtual system. After dis- persed by adopting reasonable hardware and advanced software calculation, the multipath repetition signal is transmit into the data ac- quisition card through the same transmission channel, and calculated, analyzed and disposed by using the powerful software .then the collection and recuperation of the signal of the equipment are fulfilled by using I/O port. Thus all kinds of test functi...
