摘要
受到作业环境的影响,采用传统的监控系统对拖拉机远程作业情况进行监测具有一定的难度。为了改变这种现状,提高拖拉机远程监控系统的效率和监测质量,将嵌入式DSP系统和视频压缩编码技术引入到了监控系统的设计上。所设计的系统只用一个DSP芯片和简单的外围电路,便可以完成视频的采集、压缩编码和网络传输等。采用小型嵌入式系统省去了复杂的系统移植过程,且系统具有强大的运算能力,可以对视频图像进行效率较高的压缩编码。为了验证方案的可靠性,对拖拉机监控系统压缩编码的通信质量进行了测试。失真度测试结果表明:该系统的通信质量较好,可以满足拖拉机远程监控系统的设计需求。
Due to the influence of working environment,it is difficult to monitor the remote operation of tractors by using traditional monitoring system.In order to change this situation and improve the efficiency and quality of the tractor remote monitoring system,the embedded DSP system and video compression coding technology are introduced into the design of the monitoring system.The system can complete video acquisition,compression coding and network transmission with only one DSP chip and a simple peripheral circuit.The small-scale embedded system eliminates the complex system transplantation process,and the system has strong computing power,which can compress and encode the video image efficiently.In order to verify the reliability of the scheme,the communication quality of the compression coding of the tractor monitoring system is tested.The result of distortion test shows that the communication quality of the system is good and can meet the design requirements of the tractor monitoring system.
