基于USBTMC协议的数据通信研究与实现

Study and Implementation of Data Communication Based on USB TMC Protocol

介绍了基于Slave FIFO模式的USB接口测量仪器的数据通信的原理,探讨了USB TMC协议及其子协议在某USB接口的港机设备诊断测量仪器中的实现过程。经验证,这种数据通信方法可使得基于USB接口的数据交互快速、高效,并可通过统一的VISA库函数方便快捷地为用户提供程控功能,具有较强的通用性。

This paper discusses the principle of data communication of USB interface measuring instruments based on the Slave FIFO mode. It also introduces the USB TMC protocol and its sub-protlcol in the application of the USB interface measuring in- struments. It has been proved that this data communication approach could make data interaction based on USB fast and efficient, and conveniently provide users with programmable function via unifying VISA library function and with high commonality.
