【摘要】：最近几年“物联网”这个词频繁的出现在互联网上,而且越来越受到人们的关注,早在2000年初的时候“物联网”这个词还是一个概念,如今物联网技术已经变成了现实,融入了我们的生活。同时嵌入式芯片也变得越来越成熟,不仅体积小功能强大,而且功耗也逐渐降低。在这个技术飞速发展,物质也越来越丰富的时代,如何将先进的技术更好的应用到现实生活中,使其变成为我们生活所提供方便的产品显得尤为重要。本次设计将最新的嵌入式技术和物联网技术相结合,应用国内近期兴起的MiCO物联网操作系统提出了一套局域网无线视频传输方案,系统采用模块化设计,分为上位机远程控制端和下位机数据采集端。上位机采用C#WPF编写,整合了串口调试助手与网络调试助手的经典功能,并且结合WPF Image控件强大的功能对视频流解码与显示,最后根据实际需要又添加了存储、定时等功能,实现了对下位机数据采集端的控制与数据的接收。下位机数据采集终端以目前流行的STM32F429为主控芯片,移植了国内最近兴起的MiCO物联网实时操作系统,并且搭载了与MiCO系统相匹配的EMW1062WIFI模块,通过OV2640数字摄像头采集图像信息,经过摄像头内部对数据的压缩处理,将输出的JPEG视频数据通过无线网络上传到上位机,并且可以在上位机的实时视频接收区显示出流畅的图像。经过测试,本次设计最终实现了基于STM32和MiCO的局域网无线视频传输系统,它具有结构简单、体积小、性能稳定的特点,不仅可以应用于监控领域,还可以应用于探测型机器人或无人机等领域,为人们提供远程的实时视觉信息,具有广泛的应用前景。
[Abstract]:In recent years, the word "Internet of things" has frequently appeared on the Internet, and has attracted more and more attention. As early as the beginning of 2000, the word "Internet of things" was still a concept, and now the technology of the Internet of things has become a reality. At the same time, embedded chips have become more and more mature, not only small and powerful, but also gradually reduced power consumption. In this era of rapid development of technology, more and more material, How to better apply advanced technology to real life and make it a convenient product for our life is especially important. This design combines the latest embedded technology with Internet of things technology. A wireless video transmission scheme for local area network (LAN) is proposed based on the MiCO operating system, which is developed recently in China. The system is designed by modularization, which is divided into the remote control terminal and the data acquisition terminal of the upper computer. The upper computer is programmed by C#WPF. It integrates the classic functions of serial port debugging assistant and network debugging assistant, and combines the powerful function of WPF Image control to decode and display video stream. Finally, according to the actual needs, it adds functions such as storage, timing, etc. The data acquisition terminal of the lower computer uses the popular STM32F429 as the main control chip to transplant the MiCO real time operating system of Internet of things, which is developed recently in China, and realizes the control and data receiving of the data acquisition terminal of the lower computer. And it carries the EMW1062WIFI module which matches the MiCO system, collects the image information through the OV2640 digital camera, after the compression processing of the data inside the camera, uploads the output JPEG video data to the upper computer through the wireless network. After testing, the wireless video transmission system based on STM32 and MiCO is implemented in LAN, which has the characteristics of simple structure, small size and stable performance. It can be used not only in the field of surveillance, but also in the field of detection robot or UAV, which can provide people with remote real-time visual information. It has a wide application prospect.
