【摘要】：隨著國民健康意識提高、人口老齡化加劇、以及新醫(yī)改政策的驅(qū)動,便攜式生理參數(shù)采集系統(tǒng)越來越受到重視。 關(guān)于采用DSP來采集心電、血壓、血氧及脈搏率等基本生理參數(shù)一直是DSP應(yīng)用的一個研究熱點。本文在推薦出幾種生理參數(shù)采集模塊的基礎(chǔ)上,提出了基于DSP的便攜式生理參數(shù)采集系統(tǒng)的架構(gòu),構(gòu)建了一個通用平臺。 TMS320C5000DSP平臺提供了業(yè)界功耗最低的廣泛16位DSP產(chǎn)品系列,其中TMS320VC5504/05, TMS320C5504/05/14/15, TMS320C5532/33/34/35定點數(shù)字信號處理器基于TMS320C55x V3.3CPU,面向低成本超低功耗應(yīng)用,適用于便攜式醫(yī)療電子。本論文從CPU架構(gòu)、功耗、片上資源、存儲器映射四個方面討論了所用的DSP。 便攜式生理參數(shù)采集系統(tǒng)的特點之一是低功耗,本文從主處理器DSP的電源管理到系統(tǒng)外圍模塊的電源管理進行了深入的探索,給出了具體的解決方案,并對硬件設(shè)計作了總結(jié)。 介紹了DSP開發(fā)環(huán)境Code Composer Studio v4(CCSv4)和芯片支持庫C5000Chip Support Library(CSL),在此基礎(chǔ)上,結(jié)合需求,給出了CSL使用實例。為了適應(yīng)高效的編程要求,探討了程序自動測試工具的使用方法。 結(jié)合濾波器設(shè)計與分析工具FDATool和緊耦合FFT硬件加速器HWAFFT,給出了生理參數(shù)采集系統(tǒng)中心電的濾波實例。 對生理參數(shù)采集前端通信以SPI通信為例進行了總結(jié),然后重點對基于TMS320C55x V3.3CPU架構(gòu)的DSP的片上外設(shè)USB2.0、LCD給出了調(diào)試總結(jié),最后就SD卡文件系統(tǒng)構(gòu)建及上位機獲取便攜式設(shè)備采集到的信息的方法給出了匯總方案。 在論文最后,總結(jié)了所做工作,展望了圍繞便攜式生理參數(shù)采集系統(tǒng)的研發(fā)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.
