【摘要】：随着国民健康意识提高、人口老龄化加剧、以及新医改政策的驱动,便携式生理参数采集系统越来越受到重视。 关于采用DSP来采集心电、血压、血氧及脉搏率等基本生理参数一直是DSP应用的一个研究热点。本文在推荐出几种生理参数采集模块的基础上,提出了基于DSP的便携式生理参数采集系统的架构,构建了一个通用平台。 TMS320C5000DSP平台提供了业界功耗最低的广泛16位DSP产品系列,其中TMS320VC5504/05, TMS320C5504/05/14/15, TMS320C5532/33/34/35定点数字信号处理器基于TMS320C55x V3.3CPU,面向低成本超低功耗应用,适用于便携式医疗电子。本论文从CPU架构、功耗、片上资源、存储器映射四个方面讨论了所用的DSP。 便携式生理参数采集系统的特点之一是低功耗,本文从主处理器DSP的电源管理到系统外围模块的电源管理进行了深入的探索,给出了具体的解决方案,并对硬件设计作了总结。 介绍了DSP开发环境Code Composer Studio v4(CCSv4)和芯片支持库C5000Chip Support Library(CSL),在此基础上,结合需求,给出了CSL使用实例。为了适应高效的编程要求,探讨了程序自动测试工具的使用方法。 结合滤波器设计与分析工具FDATool和紧耦合FFT硬件加速器HWAFFT,给出了生理参数采集系统中心电的滤波实例。 对生理参数采集前端通信以SPI通信为例进行了总结,然后重点对基于TMS320C55x V3.3CPU架构的DSP的片上外设USB2.0、LCD给出了调试总结,最后就SD卡文件系统构建及上位机获取便携式设备采集到的信息的方法给出了汇总方案。 在论文最后,总结了所做工作,展望了围绕便携式生理参数采集系统的研发思路。
[Abstract]:With the improvement of national health awareness, the aggravation of population aging and the drive of the new medical reform policy, the portable physiological parameter collection system has been paid more and more attention. The use of DSP to collect ECG, blood pressure, blood oxygen, pulse rate and other basic physiological parameters has been a hot spot in the application of DSP. Based on the recommendation of several physiological parameter acquisition modules, this paper presents the architecture of a portable physiological parameter acquisition system based on DSP, and constructs a general platform. The TMS320C5000DSP platform provides a wide range of 16-bit DSP products with the lowest power consumption in the industry. The TMS320VC5504/05, TMS320C5504/05/14/15, TMS320C5532/33/34/35 fixed-point digital signal processor is based on TMS320C55x V3.3 CPU and is designed for low-cost ultra-low power applications. Suitable for portable medical electronics. In this paper, DSP. is discussed from four aspects: CPU architecture, power consumption, on-chip resources and memory mapping. One of the characteristics of portable physiological parameter acquisition system is low power consumption. This paper makes a deep exploration from the power management of the main processor DSP to the power management of the peripheral module of the system, gives the concrete solution and summarizes the hardware design. This paper introduces the DSP development environment Code Composer Studio v4 (CCSv4) and the chip support library C5000Chip Support Library (CSL),. On the basis of this, an example of CSL application is given. In order to meet the requirements of efficient programming, the application method of program automatic test tool is discussed. Combined with the filter design and analysis tool FDATool and the tightly coupled FFT hardware accelerator HWAFFT, an example of ECG filtering in the physiological parameter acquisition system is given. This paper summarizes the front-end communication of physiological parameter acquisition taking SPI communication as an example, and then gives a debugging summary of the on-chip peripheral USB2.0,LCD of DSP based on TMS320C55x V3.3CPU architecture. Finally, the method of constructing SD card file system and acquiring the information collected by portable device is given. At the end of the paper, the paper summarizes the work done and looks forward to the research and development of portable physiological parameter acquisition system.
