In recent years the rapid development of 3G networks and intelligent monitoring technology to solve this problem provided the technical support. In this paper, based on the TMS320DM642 and 3G wireless data modules comprehensive monitoring system of the family of the Design and Implementation. Monitoring System Design and Implementation. The system TMS320DM642 chip for high-performance DSP core, including the video capture module, RS485 bus modules, and wireless transmission module and backup module. Can be collected at the same time three-way video and multi-channel information on the work of field devices, and motion detection for real-time situation, and then on the MPEG-4 video encoding, through the wireless transceiver module DTM6211 sent to the remote end 3G mobile phones, real-time monitoring. In this paper, then given a number-driven approach and explores the issue of motion detection algorithms. TMS320DM642 and DTM6211 also communication between the issues in detail. Finally, the full text of this article summarized and discussed some of the need to continue to deepen and improve the place, and the corresponding measures for improvement.
