摘　　要：为了解决脉搏波信号发生器与PC机的实时通信以达到下载代表不同生理意义的脉搏波波形数据的目的,设计了基于VB的通讯程序。脉搏波信号发生器采用AT89S51为中央处理器。利用USB接口和CP2101芯片实现USB转UART扩展出一个USB接口,最终用VB来实现脉搏波信号发生器与PC机之间的通讯。In order to solve real-time communication between pulse wave signal generator and PC and download different kinds of pulse wave data, we designed VB communication program. The pulse wave signal generator applied AT89S51 as its MCU. Because of USB＇ s high performance, we used USB and CP2101 to realize the conversion from USB to UART. Finally, the VB program based on PC completes the communication between pulse wave signal generator and PC.
