摘　　要：为分析高速高精控制系统中运动物体的定位情况,设计一个基于TMS320F2812的正交编码脉冲的数据采集系统。一方面,在TMS320F2812上编写数据采集程序;另一方面,采用VC++语言设计上位机应用程序。实验证明,上位机应用程序实现数据的图形显示和文本导出等基本功能,并且上位机应用程序显示的图形与其他软件显示的图形一致。该数据采集系统电路简单可靠,适用于能够产生正交编码信号的传感器的数据采集。In order to analyze the localization of moving objects in high-speed and high-precision control systems, a data acquisition system based on TMS320F2812 has been designed to collect quadrature encoder pulses. For one thing,a data acquisition program was written in TMS320F2812;for the other,PC application was designed with VC＋＋ language. The experiment demonstrates that basic functions can be realized through PC application, such as graphical data display and text export. Moreover, the graph shown on the PC application complies with that displayed on other software. The data acquisition system has simple and reliable circuit and is suitable for the data acquisition of sensors that are capable of generating quadrature encoder pulses.
