Abstract


In traditional cable network monitor, the high cost of video remote access and transmission is an important bottleneck that restricts development and application of cable network monitor. This demerit has seriously impeded the application of video monitor in a significant portion of fields and occasions. Along with the development of wireless technology, mobile operators can provide more bandwidth to transmission, so the wireless transmission technology application is accepted by more and more professions. As a special monitoring method the wireless monitoring is also gradually expected by the masses of users. At present, wireless monitoring technology has been widely used in many domains such as modern district, traffic, transportation, water conservancy, shipping, public security and fire fighting.For the shortcomings of traditional cable video monitoring system, the article designs a kind of wireless video monitoring system based on 3G wireless networking. Front-end acquisition module of system used DaVinci processor that is TI dual-core framework as core. The design included transplanting Linux operating system, compressing video data with h.264 encoding algorithm and sending data to the monitoring center through the WCDMA network. Through testing, the wireless monitoring system using this scheme can obtain clear pictures and the picture is transmitted in low delay. Above all, the cost of this system is reasonable. The equipment can be widely used in safety monitoring, traffic monitoring, industrial monitoring, house monitoring, etc which distribute in a wide range with a scattered status.This paper firstly introduces the basic structure of this scheme, system function and implementation principle, then expounds hardware design, software design and implementation of the scheme in a systematic way, finally, gives the improvement prospects and the future research direction of the scheme.
