摘　　要：设计了一种以视频分离模块LM1881对视频信号进行采集分离,在多方位使用多个监控模块,实时地对采集到的信号进行灰度差分等处理,并对处理后的数据借助NREF24L01进行无线传输,C8051F020作为移动监控设备,实时地对每个监控模块进行检测、定位特定区域的警报,并作出相应应答的系统。系统可移植性好,便于携带,有广泛的应用前景。This paper uses LPC2103 as the core, associating with LM1881 Video sync separator circuit which is used to process the video to get the signal we need,and multiple video surveillance module deal with the video signal in special algorithm such as gray level difference method in different places. Then with the cooperation of the NRF24L01 the video surveillance module transmit the data to the C8051F020 checking the data from every video surveillance module in time. After handling the data, the C8051F020 can locate where the exception comes from and send a reply to the specific LPC2103.All in all, this system has broad application prospects because of its good portability and real-time.
