传统的图像监控系统存在受地形限制的弊端，导致发现不及时和定位难的缺陷。本文设计了一种基于北斗与ZigBee技术相结合的远程图像监控系统。该系统以ARM芯片S3C2440为处理器，采用以LCD触摸屏为交互界面，运行Linux操作系统，通过前端高清摄像头采集图像信息，经视频采集压缩卡对图像进行压缩处理后，通过每个子模块的中ZigBee路由及终端节点组成的无线局域网进行数据的传输，所有信息汇总后由ZigBee协调节点模块经北斗卫星网络进行实时传输，从而达到远程图像监控的目的，经实验证明该系统具有传输稳定、使用领域广阔和覆盖面积大等优点。

Traditional monitoring system of picture is limited by the terrain, which results in untimely discovery and inaccurate location.A remote image monitoring system using both the BeiDou satellites and the ZigBee technique is presented in this paper. The proposed system uses the ARMS3C2440 as the processor, the LCD touch screen as the interface, and Linux as the operating system. The front-end HD cameras collect images, which are then compressed by the compression card. The compressed images are transmitted over the wireless LAN consisting of the ZigBee routes in each of the sub-modules and the terminal nodes. After being aggregated, all the data is sent real-time over the BeiDou satellite network via the ZigBee coordinator nodemodule. Thus, remote image monitoring is achieved. Experimental results show that the proposed system provides reliable transmission and wide coverage, and can be used in a variety of domains.
