【摘要】：老人服务产业作为一种新型的产业,越来越受到了国家的重视,将老人服务产业信息化,探索新的服务模式,对老人服务产业链的发展具有重要意义。本文以老年人服务为主要研究内容,设计了一种基于Android手机平台老人服务体系架构,并完成了具体功能模块的详细设计与开发。主要研究内容包括： (1)探索新型老人服务体系。通过物流体系将医疗、家政、生活等系统统一结合起来的新型老人服务智慧解决方案,并结合老人实际需求,完成了老年人服务功能模块设计。 (2)基于Android的摔倒检测的设计实现验证。通过详细分析日常生活事件与摔倒事件的区别,将摔倒事件进行模块化划分,过程化检测,使模型拓展改善更具有灵活性。在基于阈值摔倒检测的基础上,增加静止检测与姿态检测,有效的降低了漏报率与误报率。该摔倒算法复杂度低,效率高,经实际测试证明,该模型有较强的实用价值。 (3)老年人服务系统其他关键模块设计与实现。完成通信模块设计,选取了socket通信方案,详细设计了信令交互流程及通信报文架构；完成数据库模块设计,通过数据库功能划分,详细设计数据库表格；利用百度地图定位SDK完成终端定位、地图、路线导航、应急救援等功能实现。 (4)对老年人服务系统进行了测试验证。通过搭建测试环境,设计测试场景,对功能模块进行测试验证。实验结果表明,老年人服务系统中摔倒检测模型具有较低的误报率与漏报率,终端功能模块功能使用正常,该系统具有良好的可行性与可靠性。
[Abstract]:As a new type of industry, the service industry for the elderly has been paid more and more attention by the state. It is of great significance to the development of the industry chain for the elderly to informationalize the service industry for the elderly and explore a new service model. In this paper, the elderly service as the main research content, designed a Android mobile platform based on the elderly service architecture, and completed the detailed design and development of specific functional modules. The main research contents are as follows: (1) to explore a new service system for the elderly. A new intelligent solution for elderly service is designed by integrating medical service, housekeeping, life and other systems through the logistics system, and combining with the actual needs of the elderly, the function module of the elderly service is designed. (2) the design and implementation of fall detection based on Android. Through the detailed analysis of the difference between daily life events and fall events, the fall events are divided into modularization and process detection, which makes the development and improvement of the model more flexible. On the basis of threshold fall detection, static detection and attitude detection are added to reduce the false alarm rate and false alarm rate effectively. The algorithm is of low complexity and high efficiency. (3) Design and implementation of other key modules in elderly service system. The communication module is designed, the socket communication scheme is selected, the signaling interaction flow and the communication message structure are designed in detail, the database module is designed, and the database table is designed in detail through the database function partition. Baidu map positioning SDK to complete terminal positioning, map, route navigation, emergency rescue and other functions. (4) the service system for the elderly is tested and verified. By setting up the test environment and designing the test scene, the function module is tested and verified. The experimental results show that the fall detection model in the elderly service system has low false alarm rate and false alarm rate, and the function of the terminal function module is normal. The system has good feasibility and reliability.
