Adaptive Mobile Network Bus Video Surveillance Terminal

Abstract

The invention belongs to the technical field of vehicle monitoring technology and relates to a self-adaption mobile network bus video monitoring terminal. The self-adaption mobile network bus video monitoring terminal comprises a system core module, a data acquisition module, a human-computer interaction module, a USB (universal serial bus) concentrator module, a wireless communication module, a mobile hard disk storage module, a CAN (controller area network) bus module and an SD (security digital) card storage module. The terminal is combined with embedding technology, H.264 network video compression technology and human body identification and tracking technology, can videotape drivers and conductors in buses, front doors and rear doors and inside condition of the buses during a whole journey, and calculates the number of passengers, provides support for multiple networks, dynamically selects bearing networks according to network condition, and provides smooth real-time videos and vehicle information of passenger number, GPS (global positioning system) positioning information and so on. Therefore, by the aid of the self-adaption mobile network bus video monitoring terminal, effective monitoring to safe running of the buses and normal work of the drivers and the conductors is provided, and particularly real-time condition inside the buses can be quickly known under the condition of emergencies.

Description

Technical field [0001] The invention relates to a vehicle monitoring device, and more particularly designs a bus video monitoring terminal that automatically adjusts transmission strategies according to changes in mobile networks. Background technique [0002] With the gradual expansion of the city scale and the vigorous development of the bus passenger transport business, the urban bus passenger flow has increased significantly, and the safety and management of buses in the operation process have been paid more and more attention. Establishing a video monitoring system for real-time monitoring of buses is of great significance to bus safety and dispatching. [0003] In terms of vehicle network video monitoring, CN202168157U discloses a bus DVR monitoring system, which includes a vehicle travel recorder, a station reporting unit, an LED display, and a camera, which can provide functions such as vehicle monitoring and positioning, mileage statistics, and track storage. .
