Abstract: 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.
