Intelligent public transport multimedia system

Abstract

The invention provides an intelligent public transport multimedia system. The intelligent public transport multimedia system is mounted on vehicles and comprises a mainframe, a main board, a display module and a power wire are arranged in the mainframe, and a GPRS (general packet radio service) module, a signal acquisition module, a microprocessor unit, a storage unit and a signal output unit are integrated on the main board. The microprocessor unit receives signals transmitted by the signal acquisition module and / or the GPRS module, and by the aid of a map engine and comprehensive analysis software stored in a memory module, position information is displayed on a liquid crystal touch screen in real time through a display driving unit, and the signal output unit is controlled to output audios to a speaker for broadcasting. By integral design of signal receiving, processing and displaying and signal shielding setup of the main board, interferences are avoided, excellent audio-visual effects can be achieved, and the intelligent public transport multimedia system is applicable to various vehicles.

Description

technical field [0001] The invention relates to the field of traffic equipment, in particular to an intelligent bus multimedia system. Background technique [0002] With the development of society, more and more vehicles will be equipped with multimedia broadcasting devices. The multimedia broadcasting devices can enable passengers to obtain information, entertainment, etc. during the journey, so that the travel time is no longer boring. [0003] Usually, broadcasting devices installed on vehicles have integrated DVD players on their display parts, and some broadcasting devices pre-store pre-recorded programs and play them in a loop, but for passengers, these programs are lagging behind, It is even repeated, and information cannot be obtained in time. [0004] Some vehicles use real-time broadcasting devices, but the antennas used to receive signals are usually rod antennas. In order to obtain stable signals, the antennas are placed on the roof of the vehicle. This not only...

[0003] Usually, broadcasting devices installed on vehicles have integrated DVD players on their display parts, and some broadcasting devices pre-store pre-recorded programs and play them in a loop, but for passengers, these programs are lagging behind, Even repeated, unable to obtain information in time

[0004] Some vehicles use real-time broadcasting devices, but the antennas used to receive signals are usually rod antennas. In order to obtain stable signals, the antennas are placed on the roof of the vehicle. This not only takes time to install, but also involves complicated wiring, which affects When it comes to the overall appearance, it will even cause inconvenience to driving
