【摘要】 脉诊是中医中一项重要的方法,通过脉诊可以了解人体五脏六腑的健康状况。由于脉象理论比较复杂,诊断标准很模糊且主观因素较多,因此脉诊的客观化的研究具有重要意义。本课题中设计的人体脉搏信号监测及存储系统,可以较客观的对脉搏波进行监测和存储,为脉诊客观化的研究提供了重要的参数。本课题中设计的基于SOPC(System on a Programmable Chip)的人体脉搏信号的监测及存储系统由三部分组成,分别为系统硬件平台、SOPC平台以及软件平台。硬件平台设计,包括脉搏信号采集电路、SOPC系统电路以及PCB(PrintedCircuit Board)的设计。脉搏信号采集电路实现了对脉搏信号的放大、基线调节和AD转换。SOPC系统电路由FPGA(Field Programmable Gate Array)、SDRAM、Flash、SD/MMC卡和液晶屏等器件组成。最终将硬件平台装配成电路板。SOPC平台包括了NiosⅡ处理器的配置及各种外围模块的设计。在软件平台中实现了驱动程序和应用程序的设计,并移植了μC/OS-Ⅱ操作系统作为系统的任务管理。同时还移植了GUI(Graphics User Interface)和FAT32作为图形界面和文件系统。实验测试表明,整个系统的软硬件设计基本达到预期目标,采集到的脉搏信号准确干净,SOPC系统可正常运行。在μC/OS-Ⅱ操作系统下,各项任务运行稳定,最终实现了对脉搏信号的监测、采集、存储和串口发送等功能。更多还原

【Abstract】 Pulse diagnosis is an important method in traditional Chinese medicine, by which can obtain health status of the human organs. Due to the complexity of pulse condition theory, the standard of diagnose is vague and has many subjective factors. Therefore, the study of objectifying pulse diagnose has great significance. The human pulse signal monitoring and storage system in this paper can monitor and save the pulse waves objectively. Therefore this system can provide important references for objective study of pulse diagnosis.Based on SOPC (System on a Programmable Chip), the human pulse signal monitoring and storage system is designed in this paper consists of hardware, SOPC and software platform. The hardware platform is composed by pulse signal acquisition circuit, SOPC system circuit and PCB (Printed Circuit Board) design. The function of pulse signal acquisition circuit is to amplify signal, adjust baseline and AD convertion. SOPC system is composed by FPGA (Field Programmable Gate Array), SDRAM, Flash, SD/MMC Card, LCD, and so on. Finally the hardware platform is assembled into printed circuit board. SOPC platform includes Nios II CPU and some outer modules. In software platform we design the device driver programs, application programs, and transplantμC/OS-II to manage the system task. At the same time, GUI (Graphics User Interface) and FAT32 are transplanted in this system as the Graphics User Interface and File System.The process of system debug indicates that the hardware and software have achieved prospective target. In this system, SOPC system is running normally, and pulse signal can be collected correctly and clearly. Every task can operate stably inμC/OS-II operating system. Finally, we have realized some functions for human pulse signal including monitoring, acquisition, storage and sending.更多还原
