基于移动终端的智能监控系统设计

Design of intelligent monitoring system based on mobile terminal

随着网络信息技术的迅猛发展,人们对远程控制和性能稳定的视频监控系统提出了更高的要求,基于嵌入式的无线数字视频监控系统的研发与设计就显得尤为重要。这种无线数字监控系统可以实现许多传统有线监控系统无法实现的功能,所以无线远程视频监控正在不断地取代有线监控,在交通、银行、医院、视频会议等诸多领域发挥着越来越重要的作用。作为安防系统重要的组成部分,视频监控的嵌入式与网络化应用将是该领域的重要研究方向。该文实现的系统基于Open Wrt和ARM平台,采用MJPG-streamer软件实现图像信息的压缩、解码和传送;移动终端基于安卓平台设计应用程序;可遥控的小车配备二维云台搭载摄像头,ARM开发板控制步进电机操控云台,遥控小车移动,实现立体监视。

With the rapid development of network information technology,people set higher requirements upon remote control and the performance of the video monitoring system. For that,the research and design of wireless digital video monitoring system which based on embedded system has become pretty important. This kind of wireless digital monitoring system can achieve many functions that the traditional cable monitoring system unable to finish,therefore,the cable monitoring system are replaced by the wireless remote video monitoring constantly,besides it also plays a more and more important role in transportation,banking,hospitals,video conference and some other fields. So,as an essential part of security system,embedded video monitoring and its application in network is an important research direction in this field. The system in this paper is based on the Open Wrt and ARM platform,and to achieve the compression,decoding and transmission of image information by using MJPG- streamer software. What＇s more,this mobile terminal application is designed on the Android platform,which uses a two- dimensional platform equipped with cameras,and controls the stepper motor control platform by ARM development board to complete three- dimensional monitoring.
