【摘要】：随着社会人口老龄化程度日趋严重,“养老问题”成为必须要重视的社会问题之一,同时,智能硬件和互联网技术的蓬勃发展,促使智能技术广泛地走进了人们的日常生活,将智能技术运用到养老服务领域将成为老年照护的有效手段。本文基于STM32单片机进行智能老年照护终端设计,与多生理参数体检仪、后台服务器、前端APP共同构成智能老年照护系统。系统针对“居家养老”提出了一套远程监测老年人的活动情况和身体健康数据的智能老年照护解决方案。本智能老年照护解决方案提供了一键SOS紧急求救、日常通话、刷卡体检、在床离床状态监测、体检数据上传、电子病例管理和医生在线诊断等功能。本文主要工作如下:(1)设计智能老年照护系统的总体构架。系统设计使用GSM、GPRS通信技术实现日常通话、收发短信以及智能老年照护终端与后台服务器之间的通信,并作为系统的通信主线为系统各功能服务;使用433MHz无线通信技术实现一键SOS紧急求救功能的触发动作的传输;使用RFID(射频识别)技术实现对使用者ID的获取;使用蓝牙通信技术实现智能老年照护终端与多生理参数体检仪之间的通信,以启动体检、获取使用者生理数据;使用压力传感技术监测老年人的在床、离床状态;依托河北大学布雷尔利物联网智能技术实验室提供的后台服务器,为使用者建立电子病例档案、提供医生在线诊断;为实现解决方案中各种功能提供理论基础、可行性保障和设计方向。(2)基于STM32的智能老年照护终端设计。采用微处理器STM32F100C8T6作为系统主控芯片,设计了系统供电电路和各部分外围电路,配合以SIM800A通信模块、eV1527编码与TDH6300解码组合、RC522射频感应模块、BM70低功耗蓝牙模块、FSR408压力传感器为核心的五个功能单元电路,为智能老年照护系统的总体构架的实现提供硬件基础。在MDK环境下使用C语言,编写终端各功能单元电路的控制程序,以及系统主程序,驱动硬件电路实现系统各功能。(3)系统调试。首先对智能老年照护终端进行软硬件联调,做出智能老年照护终端样机。进而制定智能老年照护终端与系统后台服务器之间的数据通信协议,进行通信测试,实现智能老年照护解决方案。经过测试,基于STM32的智能老年照护终端具有简单、易用、功能较完善、性能稳定的特点。并且脱离WIFI环境工作,又无需其他智能终端的支持,对于老年人和老年人家庭环境均有良好的适用性。依托强大的后台服务,可对老年人进行远程的照护,建立的电子病例可作为大数据为医疗诊断提供参考。对医疗、家庭、社会都具有一定的发展意义。
[Abstract]:With the aging of the social population becoming more and more serious, the "old-age problem" has become one of the social problems that must be paid attention to. At the same time, intelligent hardware and Internet technology are booming. Intelligent technology has been widely used in people's daily life. The application of intelligent technology to the field of old-age care will become an effective means of care for the elderly. This paper based on STM32 single-chip microcomputer for intelligent elderly care terminal design, and multi-physiological parameters of physical examination instrument, background server. The front-end APP is a kind of intelligent care system for the elderly. This paper presents a set of intelligent elderly care solutions which can remotely monitor the activities and health data of the elderly. The intelligent elderly care solution provides a one-click SOS emergency call for help. Daily call, card examination, monitoring the condition of the bed off the bed, uploading the data of the physical examination. The main work of this paper is as follows: 1) to design the general framework of intelligent elderly care system. The system design uses GSM GPRS communication technology to realize daily communication. Sending and receiving short messages and the communication between the intelligent elderly care terminal and the background server, and serving as the main line of communication of the system for each function of the system; 433MHz wireless communication technology is used to transmit the trigger action of one-click SOS emergency distress function. RFID (Radio Frequency Identification) technology is used to obtain the user ID. The Bluetooth communication technology is used to realize the communication between the intelligent elderly care terminal and the physical examination instrument with multiple physiological parameters in order to start the physical examination and obtain the physiological data of the user. The pressure sensing technology was used to monitor the condition of the elderly in and out of bed. Relying on the backstage server provided by the Bradley Intelligent Technology Laboratory of Internet of things of Hebei University, we can set up electronic case files for users and provide doctors with online diagnosis. Provides the theoretical basis for the implementation of various functions in the solution. The design of intelligent elderly care terminal based on STM32. The microprocessor STM32F100C8T6 is used as the main control chip of the system. The power supply circuit and peripheral circuits of the system are designed, and the RF induction module RC522 is combined with the SIM800A communication module EV1527 coding and TDH6300 decoding. The BM70 low-power Bluetooth module has five function unit circuits which are the core of FSR408 pressure sensor. It provides the hardware foundation for the realization of the overall framework of the intelligent elderly care system. Under the MDK environment, the control program of the terminal function unit circuit and the main program of the system are compiled by using C language. Drive the hardware circuit to achieve the system functions. 3) system debugging. First of all, the intelligent elderly care terminal hardware and software adjustment. Then the data communication protocol between the intelligent elderly care terminal and the background server of the system is established, and the communication test is carried out to realize the intelligent elderly care solution. The intelligent elderly care terminal based on STM32 has the characteristics of simple, easy to use, perfect function and stable performance. It also works without the support of other intelligent terminals. For the elderly and the elderly family environment has a good applicability. Relying on strong background services, the elderly can be remote care. The established electronic case can be used as a reference for the medical diagnosis of big data, and has a certain significance for the development of medical treatment, family and society.
