3G wireless in-vehicle video monitoring system

Abstract

The invention relates to the technical field of modern electronics and specifically relates to a 3G wireless in-vehicle video monitoring system. The 3G wireless in-vehicle video monitoring system is composed of an ARM processor, a GPS module, an image acquisition module, a 3G wireless module, a power module, a clock module, and a storage module, wherein the GPS module, the image acquisition module, the 3G wireless module, the power module, the clock module, and the storage module are connected with the ARM processor. An embedded development board S3C2440 is used for establishing a hardware environment. A USB camera and the GPS module acquire the in-vehicle real-time videos and positional information. Video data is compressed and encoded high efficiently via H.264. Therefore, smooth images with high compression ratios and high quality are obtained and a data volume required to be transmitted can be greatly reduced. Using a 3G wireless network as a transmission medium solves a problem that a conventional wired network cannot monitor vehicles in motion, provides a flexible networking mode, satisfies a monitoring requirement of a monitoring point where a line cannot be established, provides a data transmission band wider than those of GPRS and CDMA, and satisfies a mobile video monitoring requirement.

Description

technical field [0001] The invention relates to the field of modern electronic technology, in particular to a 3G wireless vehicle-mounted video monitoring system. Background technique [0002] With the development of the automobile passenger transport business, the safety and management of operators in the operation process are also paid more and more attention. Due to the frequent disputes between passengers and operators due to issues such as fare evasion and service attitude, the responsibility identification of both parties in traffic accidents during passenger transportation is relatively vague, there is no strong evidence for car theft incidents, and problems such as vehicle theft and driver drunk driving are becoming more and more serious. A control system capable of real-time monitoring to better avoid these situations from happening.
