Wireless Real-time Video Transmission System of Mine Roadheader Based on H.264

The video on time transmission is one of the visualized key technologies for the remote contral of the mining and excavation equipments in underground mine.According to the underground mine production features, a new wireless on time video transmission system framework of the mine roadheader was provided and re alized.The system would apply the DaVinci platform and chip TMS320DM6446 for the video collection and compression and could realize the H.264 standard video cod e.With the 802.11 g agreement applied to the wireless transmission method with a visual transmission distance of 50~ 100 m on 2.4 GHz frequency and with a direction al antenna, the anti-interference and reliability of the system transmission channel could be improved.The measured results showed that the system could realize the 0 n time video monitoring and measuring during the operation process and status of the mine roadheader.
