本文基于 AT89S52 單片機(jī)設(shè)計(jì)了一種性價(jià)比高的移動(dòng)遠(yuǎn)程圖像監(jiān)控終端。終端在通信
協(xié)議上使用STP 協(xié)議棧。終端硬件主要包括主控部分、攝像頭部分、網(wǎng)絡(luò)傳輸控制部分以及GPS 定位部分。硬件設(shè)計(jì)中通過增加儲(chǔ)能電容以及合理的PCB 布線解決了GPRS 模塊數(shù)據(jù)發(fā)射中大脈沖電流干擾問題；通過增加外部看門狗保證了系統(tǒng)運(yùn)行可靠性。

Abstract: In this paper, we design one high performance Mobile Surveillance Camera at
the low cost. In the Mobile Surveillance Camera we adopt the stack based on STP
and construct with the controller, camera, the network controller and GPS receiver.
In the design of Mobile Surveillance we deal with current pulse with high value
through added capacitor and optimized the ground line distributing in PCB. In
particular, we design one watchdog circuit in order to ensure Mobile Surveillance
operation in reliable.
