Abstract


With the development of science and technology , the video surveillance system has been used in the field of security gradual transition from an analog system for networked digital systems , system performance monitoring system , such as coal , and other special industry also put special requirements , such as explosion-proof properties. How to implement the network monitoring system is the main research direction . This paper presents two video surveillance system embedded technology solutions : a PTZ decoder and video encoder and PC network communications , another analog PTZ decoder and video connected to the embedded video server , network traffic is then carried out by the video server . The latter method is also equivalent to the network transformation of existing equipment . In the former method , the PTZ decoder to achieve control command to receive , parse and motion control functions , is sent to the control commands from the host computer or console via Ethernet PTZ decoder . The part of the hardware ATmega128 AVR MCU core processor , through the completion of the network control chip RTL8019AS Ethernet data received . Software uIP protocol stack transplantation network data reception, data obtained from analysis of the control command command response . The video encoder to achieve the acquisition of the video data stream encoded by the transmission function via Ethernet . The hardware of this part of TI's TMS320DM642 as the core to build video processing platform RF5 framework for programming , a variety of technical support provided by TI , the functional requirements of the video encoder . In the latter method , the use of video servers and traditional PTZ decoder , camera system build , and write PC software , PC software control and real-time video monitoring system . The part of the main work is to build a half of an embedded digital system , the establishment of the monitoring system more flexibility . Conducted a detailed description of these two methods of hardware and software principles and design methods , and function of each part of the test . Currently, the function of each part has been achieved , a long period of time running in good condition .
