【摘要】：自四川数年之间连续发生大型地震之后,自然灾害已成为常态。近年来国家越来越重视防灾减灾工作,另一方面,防灾减灾工作的基础配套设施和机制却不相匹配,不仅缺乏有效的灾害防治与救助信息系统,更缺乏全社会的动员机制与参与渠道,民众的自救互救意识和能力并未培养起来,造成了许多原本可以避免的二次损失。本文正是在国家迫切需要民众和社会参与灾害救助的大背景下,提出构建一种普通民众能够以极低门槛使用的灾害防治与救助系统。这套系统的建设立足于智能手机的高普及率和自身的快速发展,利用在智能手机上得到广泛支持的Wi-Fi802.11协议所提供的定位和点对点互联通信能力,在灾难发生之后假设语音和数据通信都断绝的恶劣情况下,处于开机状态的智能手机在一定范围内能够不依赖任何基站和中心节点互相发现,进而组成临时的小型物联网,针对目标手机进行定位,利于民众自救和专业机构搜救工作的开展。本文第一章将分析建立基于智能手机的灾后救援系统的背景和价值,第二章介绍Wi-Fi应用于定位和点对点互联领域的基本概念、相关标准、协议和技术,以及手机传感器的使用及交互技术,重点对本研究所涉及的关键技术Wi-Fi Direct和Wi-Fi三角定位,加速度、陀螺仪等传感器的调用方法进行深入讨论,第三章描述整套系统结构、网络结构与开发环境,手机端构建在目前市面上主流智能手机的Android 4.4.2版本上,管理平台将基于Windows Server 2012操作系统搭建,采用apache+tomcat+php+mysql作为运行环境;第四章着重介绍手机客户端和管理平台的设计、开发与实现,最后第五章详细阐述了开发完成后的系统进行测试和交付质量保障的全过程。
[Abstract]:Natural disasters have become the norm since the occurrence of large-scale earthquakes in Sichuan for several years. In recent years, the state has paid more and more attention to disaster prevention and mitigation, on the other hand. The basic facilities and mechanisms of disaster prevention and mitigation are not matched, not only lack of effective disaster prevention and rescue information system, but also lack of social mobilization mechanism and participation channels. People's consciousness and ability of self-rescue and mutual rescue have not been cultivated, which has caused many losses that can be avoided. This paper is just in the context of the urgent need of the people and society to participate in disaster relief. A disaster prevention and relief system which can be used by ordinary people with very low threshold is proposed. The construction of this system is based on the high penetration rate of smart phones and the rapid development of their own. Take advantage of the location and point-to-point communication capabilities provided by the widely supported Wi-Fi802.11 protocol on smart phones. Assuming that voice and data communications are cut off after the disaster, a smartphone in a boot state can find each other without relying on any base station or central node to a certain extent. And then form a temporary small Internet of things, targeted at the target mobile phone location. The first chapter of this paper will analyze the background and value of establishing the disaster rescue system based on smart phone. The second chapter introduces the basic concepts, related standards, protocols and technologies of Wi-Fi application in the field of location and point-to-point interconnection, as well as the use and interaction technology of mobile phone sensors. The key technologies involved in this study, such as Wi-Fi Direct and Wi-Fi triangulation, acceleration, gyroscope, etc., are discussed in detail. The third chapter describes the whole system structure, network structure and development environment. The mobile phone is built on the current mainstream smartphone Android version 4.4.2. The management platform will be built based on Windows Server 2012 operating system, and apache tomcat php mysql will be used as the running environment. Chapter 4th focuses on the design, development and implementation of mobile phone client and management platform. Finally, chapter 5th describes the whole process of testing and delivery quality assurance of the system after development.
