Abstract

The invention provides a designing method for a third-generation (3G)-network-based wireless video monitoring system. By the method, a set of wireless video monitoring system is constructed under a simple hardware environment by utilizing the characteristics of relatively lower cost, mobility and convenience of an advanced reduced instruction set computer machine (ARM) 9 processor and a 3G network. The system is compact and based on a linux kernel so as to be convenient, easy to carry and highly extensible. A main working principle of the system is that: the system adopts a processor S3C2440A, utilizes the linux2.6.30.4 kernel, transmits video signals acquired by a universal serial bus (USB) camera to a remote terminal for displaying by the 3G network, and is optimized to a certain extent in acquisition and displaying processes. The system can be used as a cluster video monitoring system to effectively ensure the 24-hour video monitoring, remote monitoring and the like of a cluster administrator over a cluster by own characteristics of convenience and mobility. Final test results show that the system has high communication real-time performance, video transmission smoothness and relatively higher image quality.

Description

[0001] technical field [0002] The invention relates to the technical field of embedded system and linux network programming, specifically including the transplantation of linux kernel, the driving of various components, and the compilation of video collection and transmission, reception and display programs. Specifically, it is a wireless monitoring system based on 3G network. Background technique [0003] With the development of technology, people's demand for video surveillance systems is increasing. The traditional wired video surveillance system is not only complicated to install, but also has disadvantages such as difficult maintenance and inconvenient viewing of video surveillance. With the development of embedded processors and 3G networks, it is possible to build a small and light wireless video surveillance system. [0004] The present invention utilizes the linux 2.6.30.4 kernel and 3G network, and realizes a set of wireless video monitoring system on the hardw...
