本文基于 AT89S52 单片机设计了一种性价比高的移动远程图像监控终端。终端在通信协议上使用STP 协议栈。终端硬件主要包括主控部分、摄像头部分、网络传输控制部分以及GPS 定位部分。硬件设计中通过增加储能电容以及合理的PCB 布线解决了GPRS 模块数据发射中大脉冲电流干扰问题；通过增加外部看门狗保证了系统运行可靠性。关键词: 移动视频监控系统；GPRS；单片机；PCBAbstract: In this paper, we design one high performance Mobile Surveillance Camera atthe low cost. In the Mobile Surveillance Camera we adopt the stack based on STPand construct with the controller, camera, the network controller and GPS receiver.In the design of Mobile Surveillance we deal with current pulse with high valuethrough added capacitor and optimized the ground line distributing in PCB. Inparticular, we design one watchdog circuit in order to ensure Mobile Surveillanceoperation in reliable.Keyword:Mobile Video Surveillance System; GPRS; Microcontroller ;PCB
