Abstract

In view of problems of bad stability and high cost in traditional mine-used video monitoring system by use of DSP+ARM scheme,the paper proposed a design scheme of mine-used video monitoring system based on DaVinci technology.The system takes DaVinci platform based on dual-core chip DM6446 as core.DSP core uses MPEG4 algorithm to compress and code video information collected by simulated camera,then the coded video data is transmitted to ARM core through internal channel of DaVinci platform.ARM core sends the coded video data to server through UDP network and the server receives the data and makes decode and play,so as to realize video monitoring function under DaVinci platform.The experiment result showed that the system has higher reliability,but it need make a lot of field tests for coal mine use.
