【摘要】：传感器技术及移动互联网的发展日新月异,另外,智能手机的功能也日益强大,催生出参与式感知的概念。参与式感知技术提出了动态数据采集方案,每部内置传感器的移动设备均为一个感知节点。与传统感知设备相比,具有覆盖广泛、数据丰富、成本低、效率高等优势。本文将参与式感知技术应用于气象领域,解决了传统气象业务的诸多弊端。论文提出了一种基于遗传算法的激励机制优化方案。搭建了参与感知式数据共享验证系统,证实了参与感知技术在数据共享方面的可靠性。提出了一种基于Android的参与式气象共享感知系统,将传感器技术、网络通信技术、数据处理技术相结合,为用户提供了气象信息实时共享的平台。系统采用模块化的设计思想,分别由数据采集模块、数据处理模块、数据通信模块和共享查询模块四部分组成。系统通过智能手机内置传感器和外围感知设备进行气象数据采集。感知数据在Android移动终端进行有效性验证、封装、加密和本地存储处理,然后由通信机制上传至后台服务器,在服务器端进一步加工整合,并及时刷新,为用户提供实时气象信息。为满足不同用户的个性化需求,系统提供了第三方气象查询入口,气象信息以百度地图可视化的形式呈现。通过历史查询接口,用户可以浏览感知数据贡献记录。激励方案部署于服务器端,以金币积分作为报酬值,在手机终端以好友排名的形式展现,利用人们的求胜心理激励感知者积极参与任务。功能及性能测试表明,系统运行稳定,交互友好,满足用户需求,达到了研究目的。
[Abstract]:With the rapid development of sensor technology and mobile Internet, the function of smart phone is becoming more and more powerful, giving birth to the concept of participatory perception. A dynamic data acquisition scheme is proposed for participatory sensing technology. Each mobile device with built-in sensors is a sensing node. Compared with traditional sensing devices, it has the advantages of wide coverage, rich data, low cost and high efficiency. In this paper, participatory sensing technology is applied to meteorological field, which solves many disadvantages of traditional meteorological business. In this paper, an incentive mechanism optimization scheme based on genetic algorithm is proposed. A participatory perceptual data sharing verification system is built to verify the reliability of participatory sensing technology in data sharing. This paper presents a participatory meteorological sharing sensing system based on Android, which combines sensor technology, network communication technology and data processing technology to provide a platform for users to share meteorological information in real time. The system is composed of four parts: data acquisition module, data processing module, data communication module and shared query module. The system collects meteorological data through smart phone built-in sensors and peripheral sensing devices. The perceptual data is validated, encapsulated, encrypted and stored locally at the Android mobile terminal, then uploaded to the background server by the communication mechanism, further processed and integrated in the server, and refreshed in time. Provide users with real-time weather information. In order to meet the individual needs of different users, the system provides the third party meteorological query entry, and the meteorological information is presented in the form of Baidu map visualization. Through the history query interface, the user can browse the aware data contribution record. The incentive scheme is deployed on the server side, the reward value is the gold coin score, the mobile phone terminal is displayed in the form of friend ranking, and the perceptor actively participates in the task by using people's winning psychology. The function and performance tests show that the system runs stably, interactively, meets the needs of users and achieves the purpose of research.
