Abstract
A new kind of data acquisition system which is based on USB(universal serial bus) technology is designed in this paper.The advanced performance of USB with high-speed,hotplug,plug and play,easily to expand and engrossing less system resource is shown in the system.USB2.0 bus technology is introduced in this paper firstly.Then the design of the data acquisition system is discussed in detail in there are four parts: data acquisition system design,firmware design,device driver and application program.The data acquisition system based on USB bus provides a more effective,more economical and more convenient way to collect data.
