摘　　要：在此利用廉价的MCS51单片机设计了包含常用传感器、数据采集模块与USB通信接口的LabVIEW实验教学系统。该系统使用USB接口与上位机通信并提供电源,而上位机编程直接调用VISA驱动USB接口,大大降低了数据采集程序设计的难度。该系统可以满足大学虚拟仪器实验教学的需要,性价比高,具有良好的推广前景。A low cost MCSS1 MCU was used in design of a LabVIEW experiment teaching system with frequently-used sen- sor, data acquisition module and USB communication interface. USB interface was used in the system to communicate with the upper computer and supply the power to the system. The design difficulty in data acquisition program was reduced greatly by di- rectly calling USB interface driven by VISA for the upper computer programming. This system can satisfy the demand of virtual instrument experiment teaching in universities, and owns high cost performance and an excellent promotion prospect.
