摘要
为便于对远程试验目标区域进行实时视频监控,采用无线遥控发射和接收以及多通道视频等处理技术,研制具有遥控功能的远程无线多路视频处理系统。系统采用嵌入式单片机对多路视频处理芯片进行控制,根据系统串行接口接收的远程遥控指令,完成遥控指令的解码、摄像头云台控制、多路视频信号的复合、多路视频信号单路显示等处理。设计的系统成功应用于某靶场远程试验系统,具有成本低、可靠性高等特点,并取得了理想的应用效果。
To monitor the testing field of the long-distance,a remote wireless and embedded multi-channel video monitoring processing system is designed by using the telecontrol instruction transfer,receive and multi-video monitoring technologies.The embedded microcontroller is chosen to control a multi-channel video processing chip TW2823 and complete the instruction processing.After receiving the telecontrol instruction from the serial port,this system can decode the telecontrol instruction,control moving of the camera,compound the multichannel video and display the specify signal video.From the result of the testing system,the remote wireless and embedded multi-channel video monitoring processing system can satisfy the demand of the system,and has some advantages such as cheap,high reliability.
