摘　　要：设计一个上位机软件实现对采集系统数据的传输、存储、分析、绘制曲线图等功能.配合硬件系统,该软件还具有设备复位、Flash坏块检测、Flash擦除等功能.上位机软件采用VB编写主控程序,在VB中调用Matlab绘制数据曲线.文中详细介绍了基于FT245BM的USB2.0与上位机的通信原理,VB与Matlab之间的数据传递机制等关键技术.该软件已成功地用于多种采集系统的数据传输和数据处理.实验表明:该软件执行效率高、数据分析和曲线绘制速度快,适用于通用的数据采集系统.A software was designed to achieve the functions of data transmission, storage, analysis and chart drawing. Working together with an existing hardware part of a multi-channel data acquisition system, it could also achieve the functions of equipment reset, bad block checking and erasing of the Flash. The main program of the software was compiled in VB, in which the chart drawing function was realized by calling the corresponding module of Matlab. The two key technologies, the communication principle between USB2. 0 and host computer and the data transmission mechanism between VB and Matlab, were introduced. The software had been successfully applied in many data acquisition systems. It was proved that the software had the advantages of high efficiency of data transmission, data analysis and chart drawing, thus it is suitable for the general data acquisition systems.
