【摘要】：随着人们对智能化产品需求的不断扩大,嵌入式技术、数据传输技术、无线视频监控技术得到了快速的发展。与此同时,多媒体传输技术、视频图像采集技术和无线网络通信技术对智能化产品的发展和应用也产生了重大的影响。由于WIFI无线网络相比传统的通信方式具有覆盖面积大、布线比较简单、传输速度快等优势,因此能够应用在机电设备较为密集、空间范围小、环境恶劣、有线电缆布线难度大的煤矿井下,以及满足工业现场环境复杂危险的各种要求。然而,嵌入式处理器这些年来的发展迅速,它具有功耗低、体积小、经济实用、性能稳定等特点,因此越来越多的技术也朝着与嵌入式结合的方向发展,例如视频监控技术。日常生活中智能手机作为当代每个人必不可少的一种随身物品已经不再是单一的通信设备,基于智能手机作为电子控制终端的产品已经成为未来发展的一种趋势。本文提出了一种基于STM32的嵌入式微处理器无线视频监控车载系统设计方法。针对工作生活必不可少的PC机以及市场上主要流行的Android和iOS两大操作系统手机,分别介绍了一种利用PC上位机和手机来控制WIFI视频小车的方法。通过STM32主控制器来驱动小车直流电机,控制小车的各种运行状况和驱动摄像头采集视频信息；车载系统上的摄像头拍摄的视频将通过WIFI信号传给PC上位机或手机界面进行实时的显示；PC上位机或手机能够将发出的控制信号传给主控制器,从而达到了PC上位机或手机控制小车的目的。系统总体设计思想可分为软件设计与硬件设计：软件设计主要是在一定的开发平台上编写程序、设计界面按钮、实现系统的各种控制,分别设计了PC上位机以及两种不同系统手机作为整个系统的控制端；硬件设计主要是系统的电路设计,包括电机驱动模块设计、视频采集模块设计、无线通信模块设计等几部分。本文设计的无线视频监控智能小车制作出了实物,并通过了整体测试,基本功能全部实现,整体效果比较理想。本系统的成功实现对未来智能家居以及防盗系统的发展提供了研究方向。
[Abstract]:With the increasing demand for intelligent products, embedded technology, data transmission technology, wireless video surveillance technology has been rapid development.At the same time, multimedia transmission technology, video image acquisition technology and wireless network communication technology also have a great impact on the development and application of intelligent products.Compared with the traditional communication mode, WIFI wireless network has many advantages, such as large coverage area, simple wiring and fast transmission speed, so it can be used in mechanical and electrical equipment, small space range, bad environment, etc.Cable wiring is difficult in underground coal mines and meets the requirements of complex environmental hazards in industrial sites.However, with the rapid development of embedded processor in recent years, it has the characteristics of low power consumption, small size, economy and practicality, stable performance and so on. Therefore, more and more technologies have been developed in the direction of integration with embedded systems, such as video surveillance technology.In our daily life, smart phone is no longer a single communication device as a necessary personal item for everyone. As a product of electronic control terminal, smart phone has become a trend in the future.This paper presents a design method of embedded microprocessor wireless video surveillance vehicle system based on STM32.This paper introduces a method of controlling WIFI video car by using PC and mobile phone, which is necessary for work and life, as well as two popular mobile phones such as Android and iOS, which are popular in the market.The main controller of STM32 is used to drive the DC motor of the car, to control the running condition of the car and to drive the camera to collect the video information.The video captured by the camera on the on-board system will be transmitted to the PC or the mobile interface through the WIFI signal for real-time display. The PC PC or the mobile phone can transmit the control signal to the main controller.In order to achieve the PC PC or mobile phone control car purpose.The overall design of the system can be divided into software design and hardware design: software design is mainly to write programs on a certain development platform, design interface buttons, and achieve various control of the system.PC and two different system mobile phones are designed as the control end of the whole system, the hardware design is mainly the circuit design of the system, including motor driving module design, video acquisition module design,Wireless communication module design and other parts.The wireless video surveillance intelligent car designed in this paper has made the object, and passed the whole test, the basic function is realized completely, the overall effect is quite ideal.The successful realization of this system provides a research direction for the future development of smart home and anti-theft system.
