基于DSP技术的数据采集系统设计

摘要

In the development of multi‐power supply system in China ,it is necessary to study the data acquisition system for accurate detection of power supply in order to realize the real‐time control of multi‐ple power supply safety switch .This paper presents a design scheme of data acquisition system which can be used for dual power supply device .The scheme adopts the high‐speed TMS320F2812 processor of TI Company as the main control chip .It carries out the real‐time detection and real‐time control to the state of common and standby power using the full wave rectifier circuit and two order active filter circuit to realize the continuous pow er supply to the load .%在我国多路电源供电系统发展中，为了实现实时控制多路电源安全切换，研究能够精确检测电源状态的数据采集系统是必要的。本文提出了一种能够用于双电源供电装置的数据采集系统设计方案。该方案采用了TI公司的高速处理器TMS320F2812作为主控芯片，通过全波整流电路和二阶有源滤波电路对常用和备用电源的状态进行实时检测和实时控制，实现了对负载的连续供电。
