Digital-multimedia-broadcasting-based vehicle-mounted traffic information terminal

Abstract

The present invention proposes a vehicle-mounted traffic information terminal based on digital multimedia broadcasting, which is installed on a vehicle and includes: an antenna and a host, and a host board, a display module and a power cord are arranged in the host; a GPRS module, a signal Acquisition module, microprocessor unit, storage unit and signal output unit; the microprocessor unit receives the signal transmitted from the signal acquisition module and / or GPRS module, and combines the comprehensive analysis software and the map engine stored in the storage module, through the display The drive module displays real-time location information on the LCD touch screen, and simultaneously controls the signal output unit to output audio to the speaker for broadcasting. The information terminal has its own small antenna, which integrates signal receiving, processing and display, and sets up signal shielding between the motherboard and the antenna so that they do not interfere with each other and can achieve good audio-visual effects. in various means of transportation.

Description

technical field [0001] The invention relates to the field of traffic equipment, in particular to a vehicle traffic information terminal based on digital multimedia broadcasting. 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 place...

Problems solved by technology

[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
