基于Hi3512的3G视频监控终端的设计与实现
Design and implementation of 3G video surveillance terminal based on Hi3512 chip
摘要
Abstract
To meet the needs of remote video surveillance and information service in a traffic system , a design method of video surveillance system based on GPS position technique and 3G network is presented according to the needs analysis. A project of a 3G video surveillance terminal based on embedded system is provided by using Hi3512 chip made in HISILICON Company, which integrates H264 codes as CPU of the embedded system. Video is transmitted by wire and wireless network. Lost package retransmission mechanism is adopted to ensure the reliability of network transmission. Based on hardware and software design, the project is introduced in detail, including video capture, video compression, video storage, video transmitting, GPS location, system control. Test results show that this terminal provides high resolution dynamic video and precise vehicle orientation, and it runs steadily and reliably in the system.关键词
