【摘要】：随着物联网技术的发展,智能监测技术正在日益深入人们的日常生活,并且在社会各行业发挥着越来越重要的作用。目前,传统的监测技术以其被动、实时性差、人机交互性差等特点,已经不能满足用户的需求。智能监测利用先进的综合布线、网络通信、多节点传感器组网和音视频技术,将监测的各种设备互联到一起,构建方便统一安全性高的监测网络,能够将所有数据上传到云端,在云端完成数据的存储和分析,然后云端提供接口,各种客户端可以下载并以合适的方式显示数据。基于以上背景和吉林省科技厅重点科技攻关项目,本文设计了一套功能完善的智能监测系统,包括ZigBee无线传感器组网、Android手机端开发以及相关中间件的设计与实现。这套系统是分为数据采集端、PC端、服务器端、Android手机端等四部分设计与实现的。在数据采集端,实现火灾信息传感器选型和信号的提取及处理;建立自组织的ZigBee无线传感器网络平台,保证数据的传输可靠且高效。在PC端,PC作为ZigBee协调器和云服务器通信的中间件,一方面,通过PC的串口通信实现与传感器网络的信息交互,另一方面,通过HTTP协议与云服务器实现信息交互。在服务器端,研究服务器/客户端网络框架及Linux内核命令行的操作,实现云服务器配置、网络通信接口的程序编程以及My SQL数据库的搭建,保证在公网架构起数据可靠,传输稳定的服务。在Android端,研究Android的网络架构,利用JSON数据交换格式实现采集端-PC端-服务器端-手机端的数据实时通信;研究多线程编程,实现app内相关功能;研究网络摄像机,并嵌入app中实现视频监控。在完成开发后,对系统的各部分和整体进行了测试。测试结果表明,该系统各个模块功能无误,坚固可靠,整个系统的设计合理,功能完善,达到预期效果。
[Abstract]:With the development of Internet of things (IoT) technology, intelligent monitoring technology is increasingly deepening into people's daily life, and plays an increasingly important role in various sectors of society. At present, the traditional monitoring technology can not meet the needs of users because of its passive, poor real-time, poor man-machine interaction and other characteristics. Intelligent monitoring uses advanced integrated cabling, network communication, multi-node sensor networking and audio and video technology to connect all the monitoring devices together, and to build a monitoring network that is convenient and safe, and can upload all the data to the cloud. The data is stored and analyzed in the cloud, and then the interface is provided in the cloud. Various clients can download and display the data in the appropriate way. Based on the above background and the key science and technology project of Jilin Provincial Science and Technology Department, this paper designs a set of intelligent monitoring system with perfect function, including the development of ZigBee wireless sensor network and Android mobile phone and the design and implementation of related middleware. This system is divided into four parts: data acquisition terminal PC end, server end and Android phone terminal. At the data acquisition end, the fire information sensor selection and signal extraction and processing are realized, and the self-organized ZigBee wireless sensor network platform is established to ensure reliable and efficient data transmission. As the middleware of communication between ZigBee coordinator and cloud server, on the one hand, PC communicates with sensor network through serial port communication of PC; on the other hand, it interacts with cloud server through HTTP protocol. On the server side, the operation of the server / client network framework and the Linux kernel command line is studied, the configuration of the cloud server, the programming of the network communication interface and the construction of my SQL database are realized, so as to ensure the reliability of the data from the public network architecture. Stable transmission of services. At the Android end, the network architecture of Android is studied, and the real-time data communication between the collecting end and the server end is realized by using the JSON data exchange format; the multithread programming is studied to realize the related function in app; the network camera is studied. And embedded in app to achieve video monitoring. After the completion of the development, the various parts and the whole system were tested. The test results show that the function of each module of the system is correct, solid and reliable, the design of the whole system is reasonable, the function is perfect, and the expected effect is achieved.
