For energy spectrometer, the upper machine needs communicating with a plurality of components of lower machine. This paper gives a scheme that data communication is realized through USB￣HUB integrated on the control panel. This scheme is ana￣lyzed from two aspects of hardware circuit and software programming. The matters needing attention in design are described. The ex￣perimental result shows that the scheme is used to realize fast and stable data transmission and reduce the number of interfaces be￣tween host and lower machine and it is convenient for the use of the operators.
