【摘要】：水利移民实物指标数据是水利移民工作的数据基础和事实依据,其数据量大、种类繁杂,前期需对数据统计汇总分析,后期也有管理需求。现有实物指标数据采集管理系统存在着定位难、测量难、记录难的问题。在野外工作环境下,流动性大、便携性及用户体验差,更容易带来成本高、数据时效性低的问题。为了提高工作效率、降低生产成本,本文在分析已有数据采集技术和移民数据的数据特点的基础上,对移动环境下移民数据的采集和传输进行了研究,分为数据采集流程设计以及移动环境下的数据传输两个方面。 1.面向移动设备的移民数据采集流程设计目的是,明确调查各阶段承接关系,为进一步获取数据指明了方法和方向,改变了移民数据采集的传统工作方式。 2.移动环境下实物指标数据传输研究目的是,优化移动环境下实物指标数据传输问题。数据传输策略方面借鉴实时数据处理事务的优先级思想,结合数据特性及传输特性需求,提出四种基于优先级的数据传输策略,且最终提出了混合传输策略。在数据传输效率上,实现了基于RESTful风格的ProtoBuf格式的数据传输,提高了传输效率。最后,本文结合GIS技术、无线定位及无线通讯技术,将数据采集流程融入到系统的构建之中,建立了易于部署和管理的Mobile-Server架构,设计实现原型系统,以满足水利移民数据采集的迫切需求。
[Abstract]:The physical index data of water conservancy migrants is the data basis and factual basis of the water conservancy migration work, its data amount is large, the kinds are complicated, the data need to be collected and analyzed in the early stage, and there is also the management demand in the later stage. The existing data acquisition and management system of physical indicators is difficult to locate, measure and record. In the field work environment, high mobility, portability and poor user experience are more likely to bring about the problems of high cost and low data timeliness. In order to improve the work efficiency and reduce the production cost, based on the analysis of the existing data acquisition technology and the characteristics of the migration data, this paper studies the migration data collection and transmission in mobile environment. It is divided into two aspects: data acquisition flow design and data transmission in mobile environment. 1. The purpose of the design of migration data acquisition flow oriented to mobile devices is to define the relationship between different stages of investigation, to point out the method and direction for further data acquisition, and to change the traditional working mode of migration data collection. 2. The purpose of this study is to optimize the transmission of physical index data in mobile environment. In the aspect of data transmission strategy, four priority-based data transmission strategies are proposed based on the priority idea of real-time data processing transactions, and combined with the data characteristics and transmission characteristics. Finally, a hybrid transmission strategy is proposed. In the aspect of data transmission efficiency, the data transmission based on RESTful style ProtoBuf format is realized, and the transmission efficiency is improved. Finally, combining with GIS technology, wireless positioning and wireless communication technology, this paper integrates the data acquisition process into the system construction, establishes the Mobile-Server architecture which is easy to deploy and manages, and designs and implements the prototype system. In order to meet the urgent need of data collection of water conservancy migrants.
