【摘要】 根据最新中国人口数据统计,60岁以上人口占总人口数的比重已经超过15%,人口老龄化态势明显,然而护理资源相对短缺。医学实践表明,老年人一旦出现意外情况时,需要专业的医护人员及时处理,否则会危及生命。为了提高发现意外情况的及时性,减轻医护人员巡视的工作强度,老年人实时监护系统的研究正得到越来越多的关注。本文针对老年人室内状况实时监护的需求,设计并研制了一套基于多传感器的室内养老监护系统,解决了护理人员不能及时发现室内老年人发生意外情况的问题。本文首先描述了国内外对于室内养老监护系统的研究状况并总结了存在的不足。然后从整个养老室内监护系统的结构设计和通信方式选择开始,阐述了组成室内监护系统的各个子系统的组成结构以及硬件电路的详细设计。接着,详细说明了室内养老监护系统的各个子系统的检测算法,同时引入有限向量机(FSM)的方法来说明检测算法中传感器的状态变化过程。最后依据上述检测算法进行了一系列的测试实验,通过修改实验中装置的参数和实验的环境,设置对照实验,论证实验装置硬件结构设计的合理性和实时检测算法的有效性。本文阐述的多传感器室内养老监护系统在结构设计及检测算法上具有低成本,对安装环境要求低,接口简单,使用方便,检测效果好等特点。更多还原

【Abstract】 According to Chinese latest census figures,it shows the number of the old people who is more than 60 years old already beyond 15% of the whole population.From which,we can see the aging population trend is obvious but the elderly are lack of nursing resources.The medical practice shows the elderly need professional treatment in time when some emergency happened to them,or else their life will be in danger.To find the emergency happened to the elderly in time,meanwhile to improve the working efficiency of the nursing people,the study of real-time monitoring for the elderly raised more and more attention.This paper puts forward an indoor monitoring system based on multiple sensors to meet the needs of real-time monitoring for the elderly indoor,through which,the nursing people will receive information in time when some emergencies happened to the elderly indoor.Firstly,it introduces the research status on indoor monitoring systems and summarizes its existing disadvantages.Secondly,it starts with the construction design and communication way choosing of the whole indoor monitoring system,explains the sub-system’s composition structure and hardware circuit design.Thirdly it describes the detective methods for all sub-systems,meanwhile it brings in the finite state machine(FSM)to check the changing status of the sensors.At last,it conducts a series of experiments based on the previous mentioned detecting methods,and by contrast,it carries out tests under different test parameters and the test environment to prove the effectiveness of the detecting methods and the rationality of the equipment construction design.This system has many advantages such as low cost,easy to be installed,very convenient to be used and good detective effect,which could be widely used for improving the quality living life of the elderly.更多还原
