基于DM365的井下多媒体监控系统设计

针对现有井下监控系统由于采用有线方式传输而存在布线难、网络覆盖不全及由于监控网络相互独立而造成成本高等问题,提出了一种基于DM365的井下多媒体监控系统的设计方案。该系统选用DM365视频处理芯片为硬件平台,嵌入式Linux操作系统为软件平台,集传感器无线数据传输和视频监控功能于一体,可对井下现场的视频、设备工作状况以及甲烷气体体积分数、湿度和温度等多维环境信息进行监测。实验结果表明,该系统提高了视频图像的处理能力,满足了井下无线传输距离的要求,适合在能量有限的煤矿井下使用。

Design of underground multi-media monitoring and control system based on DM365

For disadvantages of wiring difficult,incomplete network coverage because of using wire transmission and high cost because of independent of monitoring networks exited in underground monitoring and control system,a design scheme of underground multi-media monitoring and control system based on DM365 was put forward.The system uses DM365 video processing chip as hardware platform,embedded Linux as software platform,and integrates wireless data transmission of sensor and video monitoring,which can monitor data of underground video,equipment working conditions,gas concentration,humidity,temperature and other multidimensional environment information.The experiment result shows that the system improves video image processing capabilities,meets with requirements of the underground wireless transmission distance,and is suitable for use in a limited energy of coal mine.
