Design of USB interface application based on NI-VISA and Labview

Abstract LabView is an environment of virtual instruments, remote monitoring and control and other field of common programming. It make Labview communicate with all types of external communication interface based on VISA. And the Universal Serial Interface USB has become the standard interface for all types of equipment and instruments, and it’s widely used in data acquisition and remote monitoring and control. But driven design of USB interface is more complex, and need higher programming skills of designers. This object is design USB serial application by NI-VISA based on environmental data collection of greenhouse, read environment data through the USB interface from the lower machine, and design the interface of display and control by Labview.. Effective connectivity PC and lower machine, it’s more easy and solve the problem of complexity of the USB drive effectively.
