Video monitoring system based on 3G mobile communication technology

Abstract

The invention discloses a mobile video monitoring system which achieves a digital video compression function and a 3G wireless transmission function by utilizing an SOC (System on a Chip) single-chip multimedia processor and a 3G wireless communication system. The mobile video monitoring system comprises a 3G wireless network camera body, a video input device and an audio input device; and the wireless communication system can be accessed to a 3G mobile wireless communication network, a Wifi wireless Ethernet or an Ethernet. The 3G wireless network camera uses the SOC single-chip multimedia processor as the core, and is externally connected with a data storage SDRAM (Synchronous Dynamic Random Access Memory), a program storage NANDFlash, a CMOS (Complementary Metal Oxide Semiconductor) sensor camera or a video analog-to-digital (AD) converter, an audio AD converter, a 3G wireless communication module, a Wifi wireless Ethernet module and an Ethernet module. The 3G wireless communication module and the Wifi wireless Ethernet module are connected with a radio-frequency antenna and a radio-frequency circuit; and the video AD converter and the audio AD converter are respectively provided with a video input interface and an audio input interface. The SOC single-chip multimedia processor achieves a video encoding / decoding function, a wireless transmission function and a control function by using a Linux real-time operation system.

Description

Technical field: [0001] The patent of the present invention belongs to the technical field of network video monitoring, and in particular relates to a digital video monitoring system supporting 3G network wireless transmission. Background technique: [0002] At present, network video surveillance equipment is widely used in public places and private residences such as living quarters, shopping malls, factories, urban transportation, etc., and plays an important role in corporate public safety, corporate management, and personal and property safety.

Problems solved by technology

[0002] At present, network video surveillance equipment is widely used in public places and private residences such as living quarters, shopping malls, factories, urban transportation, etc., and plays an important role in corporate public safety, corporate management, and personal and property safety. Most of the network video surveillance equipment is based on wired network or wireless local area network (Wifi / WAPI) for video data transmission and communication. Applications in places where wired network resources are insufficient, such as mobile vehicles, field workplaces, construction of buildings and bridges, temporary monitoring and handling of emergencies, etc.

In these fields, traditional network video surveillance equipment is basically unable to be applied

In addition, the wiring of traditional network monitoring equipment is complicated in network construction, and it is difficult to troubleshoot and repair, which is not conducive to the later maintenance and update of equipment.
