基于DSP的信号处理系统的设计

Design of signal process system based on DSP

根据井下信息处理的需要,本文设计了一种基于TMS320F2812的信号处理系统。采用具有AD模数转换功能的32位DSP芯片TMS320F2812实现井下信息的实时采集处理,将处理后的数据通过SCI(串行异步通信接口)传送到PC,由PC的串口调试工具对接收信号进行实时显示和具体分析并将结果反馈给DSP进行控制。本文对硬件和软件设计进行了详细描述,该系统具有很高的可靠性和通用性,具有高速数据采集功能。12位的精度完全满足现场对数据精度的要求。

According to the needs of welldown signal process,the paper designs a signal process system based on TMS320F2812 which have function of AD conversion with 32.To achieve the timely process of welldown signal,the paper uses the TMS320F2812 chip of DSP,which sends the data to PC through UART,the comtools show and analyse the received signals,and feed back the results to the DSP to be controlled.The article mainly elaborates the hardware and software of systems,the systems have a high dependability,universal and data logging function.12-bit precision for data accuracy of the site fully meet the requirements.
