【摘要】：随着社会老龄化的加剧以及护理人员的紧缺，患病高危人群的看护疏漏问题日益突显。如何在无人看护情况下有效获取患者的相关生理参数变得尤为重要。传统的医疗监护设备存在体积大、成本高、不方便携带等缺点，所以开发新型的可佩戴式健康监护系统，在日常健康检查、病人康复等方面都具有十分重要的实用价值。针对这样一种诉求，，课题利用SOPC技术和嵌入式技术，设计了一种便携式可佩带的健康监护系统。系统从物理实现上分为信息采集端和医疗监护端。在被监护的患者一端佩带信息采集端，可在低生理、心理负荷条件下获取人体日常姿态、体温、脉搏、心电等信息。这些信息通过无线和串口传输的方式传输至医疗监护端进行处理，判断测试者的健康水平，在发现生理异常时自动短信报警，同时利用轻量级GUI图形库构建的人机交互界面，提供直观的数据及波形供医疗人员分析。论文以嵌入式Linux系统的交叉开发过程为主线，介绍系统中的设计内容及技术要点，主要侧重于系统硬件设计、软件设计的阐述。硬件设计主要包括硬件电路的设计与SOPC系统的搭建，具体内容有：电源模块、传感器模块、STM32控制器、GPRS模块以及无线模块外围电路设计，以及可运行嵌入式Linux系统SOPC系统的搭建与设计。软件设计主要有嵌入式系统的移植以及应用程序的编写，主要内容包括：适用于FPGA平台的嵌入式Linux系统内核的裁剪与配置、驱动的移植、FTK图形库的移植以及多线程应用程序的编写。详细讲述了基于FPGA的嵌入式系统的开发方法，包括应用程序编写、编译调试所使用工具方法，以及硬件下载、烧写所需要的步骤等。系统利用自主设计的电路板实现了患者低负荷的目标，利用无线技术实现了远距离监控的目的，利用GPRS技术结合控制器处理功能实现了短信报警功能，利用嵌入式系统技术实现了有效管理设备、运行多线程应用程序以提高响应速度的目的，利用嵌入式图形库技术实现了友好人机交互的目的，最终实现了一个具有简单易用、灵活便携、多参数采集、自动报警特点的健康监护系统。
[Abstract]:With the aggravation of the aging society and the shortage of nursing staff. The problem of nursing omission of high risk population is becoming more and more serious. It is very important to obtain the physiological parameters of patients effectively under the condition of unattended care. The traditional medical monitoring equipment is large in size and high in cost. Therefore, the development of a new wearable health monitoring system is of great practical value in the aspects of daily health examination and patient recovery. For such a demand, the subject uses SOPC technology and embedded technology. A portable wearable health monitoring system is designed. The system can be divided into information collection end and medical monitoring terminal physically. Under the condition of psychological load, the body's daily posture, body temperature, pulse, ECG and other information are obtained. These information are transmitted to the medical monitoring terminal by wireless and serial transmission to judge the health level of the subjects. At the same time, the human-computer interface constructed by lightweight GUI graphics library is used to provide intuitive data and waveform for medical personnel to analyze. Taking the cross-development process of embedded Linux system as the main line, this paper introduces the design contents and technical points of the system, mainly focusing on the hardware design of the system. Software design. Hardware design mainly includes hardware circuit design and SOPC system construction, the specific contents are: power module, sensor module STM32 controller. GPRS module and wireless module peripheral circuit design. As well as the running embedded Linux system SOPC system construction and design. The software design mainly includes the embedded system transplantation and application programming. The main contents are as follows: the kernel of embedded Linux system suitable for FPGA platform is clipped and configured, and the porting of driver is also introduced. The development method of embedded system based on FPGA is described in detail, including application programming, compiling and debugging tools. And hardware download, burning the necessary steps and so on. The system uses the self-designed circuit board to achieve the goal of low load, the wireless technology to achieve the purpose of remote monitoring, the use of GPRS technology combined with controller processing function to achieve the SMS alarm function. The purpose of managing equipment effectively and running multi-thread application program to improve response speed is realized by using embedded system technology, and friendly man-machine interaction is realized by using embedded graphics library technology. Finally, a health monitoring system with the characteristics of easy to use, flexible and portable, multi-parameter collection and automatic alarm is realized.
