【摘要】：随着嵌入式技术的进一步发展,融合物联网技术的嵌入式是未来发展的趋势。物联网体系中将感知层的信息采集作为基础,通过网络层实现信息的传输,最后由应用层进行统一的管理。本课题从感知信息出发,利用嵌入式系统进行信息采集,通过3G网络进行数据传输,并由远程应用服务中心进行统一的监控。本文基于嵌入式技术与无线移动通信技术实现了物联网数据采集系统的开发,主要研究内容有：(1)设计了物联网数据采集系统的总体架构,系统由感知终端和应用服务中心构成。感知终端选用S3C2440开发板作为核心,进行远程信息采集,通过3G网络传输数据；应用服务中心采用VC++6.0作为软件开发环境,实现对感知终端的远程管理与数据分析。(2)对感知终端进行了软硬件设计。运用ARM9、传感器、摄像头、3G无线上网卡等实现终端硬件平台搭建。同时进行数据采集软件的设计,自定义了感知终端和应用服务中心的通信协议,设计了传感器驱动程序与应用程序,深入研究了H.264编码、motion运动检测和OpenSSL算法后设计了视频监控与远程安全升级程序。(3)通过VC++6.0开发应用服务中心的数据管理软件,并选用SQL Server2012作为数据库管理系统。深入研究了线程池、数据处理变换算法以及数据库访问技术,设计了网络通讯程序、数据处理及显示程序、用户信息管理程序等。通过对系统的测试,验证了系统的可行性,其可广泛应用于家庭、医疗、工厂等领域,具有巨大的实用价值和广阔前景。
[Abstract]:With the further development of embedded technology, the integration of Internet of things embedded technology is the trend of future development. In the Internet of things (IoT) system, the information collection of the perceptual layer is taken as the basis, the information is transmitted through the network layer, and the management is unified by the application layer. From the perspective of perceptual information, this paper uses embedded system to collect information, transmit data through 3G network, and monitor and control by remote application service center. Based on embedded technology and wireless mobile communication technology, this paper realizes the development of data acquisition system of Internet of things. The main research contents are as follows: (1) the overall architecture of data acquisition system of Internet of things is designed. The system consists of a sensing terminal and an application service center. The sensing terminal selects S3C2440 development board as the core, carries on the remote information collection, transmits the data through the 3G network; The application service center adopts VC 6.0 as the software development environment to realize the remote management and data analysis of the perceptual terminal. (2) the software and hardware of the perceptual terminal are designed. Use ARM9, sensor, camera, 3G wireless network card to achieve terminal hardware platform. At the same time, the data acquisition software is designed, the communication protocol between the sensing terminal and the application service center is defined, the sensor driver and the application program are designed, and the H.264 coding is deeply studied. The program of video surveillance and remote security upgrade is designed after motion detection and OpenSSL algorithm. (3) data management software of application service center is developed through VC 6.0, and SQL Server2012 is selected as database management system. The thread pool, data processing and transformation algorithm and database access technology are deeply studied. The network communication program, data processing and display program, user information management program and so on are designed. The feasibility of the system is verified by testing the system. It can be widely used in the fields of family, medical treatment, factory and so on. It has great practical value and broad prospect.
