【摘要】：随着政治、经济、文化等社会各个方面的飞速发展,尤其是现代信息技术的发展,犯罪呈现出高智商、事发前计划严谨、现场遗留线索少、侦破困难；作案跨时间跨地域、跨省跨国犯罪屡见不鲜,执法的地域性限制问题严重。国家很早就意识到了信息化建设对新世纪警务工作的巨大变革作用,如果想铸就一支新世纪的强大公安队伍,就要依托高度信息化的公安警务系统。为增强公安干警在现代经济条件和社会条件下迅速出击、统一指挥、快速准确的情报收集的能力。一方面,一线干警在执行警务时候,一个很重要的事情就是时时与指挥中心沟通；另一方面,现代犯罪呈现跨行业的势头,一些大案要案往往涉及司法、税务、海关、工商等各个部门,调查取证往往需要调集各个部门的数据,如果有一个可以快速查询、分析、整合的信息平台将极大的提高公安干警的工作量。最近几年,信息技术发展非常迅速,基础通信网络覆盖面积越来越广,同时伴随着第三代与第四代通信技术的发展,网速的信息传输速度也越来越快,移动互联网发展愈发蓬勃,这为移动警务系统的建设提供了网络基础,快速稳定的通信网络使智能手机等PDA成为信息获取与传输的终端节点,是移动互联网的关键一环。基于以上,本文开发了一种便携、可手持的移动警务平台,具有很强的现实意义。本文的主要工作是研究“基于Android的公安移动警务系统”的设计与实现。对“基于Android的公安移动警务系统”切实调研了功能需求,研究了相关技术,完成了软件的总体设计。本文的主要研究工作与内容如下： 1、学习了Android系统的应用开发技术,研究了Android系统架构。学习了Android在SDK以及NDK环境下开发的基本步骤、开发环境的配置。着重进行了Android系统的组成分析、Android系统的数据安全传输策略。 2、本文分析了系统的功能需求基础,以及使用该软件系统的用户习惯与业务处理流程,完成了“基于Android的公安移动警务系统”的总体设计。 3、本文对项目开发进行了分层分析,完成了系统的拓扑结构与E-R图。完成了软件系统的逻辑模型与物理模型。根据对功能需求的分类整理,完成子模块的划分。 4、本文最后对研究工作进行了总结与分析,分析了本文存在的不足,并根据研究过程中的思考提出了在后续工作中,要注重系统数据的安全。
[Abstract]:With the rapid development of politics, economy, culture and other aspects of society, especially with the development of modern information technology, crime presents a high intelligence quotient, rigorous planning before the incident, fewer clues left on the scene, and difficulties in detection. Cross-provincial transnational crime is common and the regional restriction of law enforcement is serious. The country has realized the great change function of the information construction to the police work in the new century very early. If we want to cast a strong police force in the new century, we must rely on the highly information police service system. In order to enhance the ability of police to attack quickly under modern economic and social conditions, to unify command, and to collect information quickly and accurately. On the one hand, a very important thing for front-line police officers to carry out is to communicate with the command center from time to time. On the other hand, modern crime is showing a cross-industry momentum. Some major cases often involve justice, taxation, and customs. Industry and commerce and other departments, the investigation of evidence often need to mobilize the data of each department, if there is a quick inquiry, analysis, integration of information platform will greatly improve the workload of police officers. In recent years, with the rapid development of information technology, the basic communication network covers more and more widely. With the development of the third and fourth generation communication technology, the information transmission speed of the network is also getting faster and faster. The development of mobile Internet is more and more vigorous, which provides the network foundation for the construction of mobile policing system. The rapid and stable communication network makes PDA such as smart phone become the terminal node of information acquisition and transmission, which is the key link of mobile Internet. Based on the above, this paper develops a portable, handheld mobile police platform, which has a strong practical significance. The main work of this paper is to study the design and implementation of Police Mobile Policing system based on Android. This paper investigates the functional requirements of the Police Mobile Policing system based on Android, studies the related technologies, and completes the overall design of the software. The main research work and contents of this paper are as follows: 1. The application development technology of Android system is studied, and the architecture of Android system is studied. Learn the basic steps of Android development in SDK and NDK environment, the configuration of the development environment. The data security transmission strategy of Android system is analyzed emphatically. 2. This paper analyzes the functional requirements of the system, the user habits and business process of the software system, and completes the overall design of the "Police Mobile Policing system based on Android". 3. In this paper, the hierarchical analysis of the project development is carried out, and the topological structure and E-R diagram of the system are completed. The logical model and physical model of the software system are completed. According to the classification of functional requirements, complete the submodule division. Finally, this paper summarizes and analyzes the research work, analyzes the shortcomings of this paper, and points out that in the follow-up work, we should pay attention to the security of the system data.
