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

Abstract

The invention provides a digital-multimedia-broadcasting-based vehicle-mounted traffic information terminal installed on a vehicle. The terminal comprises an antenna and a host. A main board, a display module and a power cord are arranged in the host; a GPRS module, a signal acquisition module, a microprocessor unit, a memory unit and a signal output unit are integrated to the main board; the microprocessor unit receives signals transmitted by the signal acquisition module and / or the GPRS module; with combination of integrated analysis software and a map engine stored into the memory module, location information is displayed in real time at a liquid crystal touch screen by a display drive module; and the signal output unit is controlled to output an audio frequency to a loudspeaker for broadcasting. The information terminal is provided with the small antenna and employs an integrated design with the signal receiving, processing and displaying functions; and a signal shielding unit is arranged between the main board and the antenna to avoid the mutual interference, so that the good hearing effect is realized. The terminal is suitable for various vehicles.

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
