Stand and sound while ring and cause passenger is mixed to listen, disclosure satisfy that the different installation environment of bus, provided to user and passenger more
It is convenient, it is simple in construction, it is easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model includes terminal body, set on the terminal body and also have DTMB antennas, it is described
Terminal body includes main control circuit, memory, modem, signal tuning device, frequency switch circuit, 4G antennas, GPS/
Beidou antenna, split-screen display and GPS/ Big Dipper dual-mode terminals, the FPDP of the memory connect with the main control circuit
Connect, the signal port of the DTMB antennas is connected with the signal port of the signal tuning device, the output of the signal tuning device
End is connected with the input of the modem, the output end of the modem and the input of the main control circuit
Connection, the input of the output end of the main control circuit respectively with the Audio conversion module are connected, the Audio conversion mould

Connect, the split-screen display is at least two groups.
The memory includes SD card and and Flash flash cards.
Infrared remote control receiver is provided with the terminal body.
Operation principle of the present utility model is as follows：
The high-frequency signal frequency conversion output intermediate-freuqncy signal that DTMB antennas receive is sent to modem by signal tuning device
Afterwards, modem output TS stream signals are sent to main control circuit and decoded, and carry out data buffer storage；Flash storage with
Primary processor is connected into line program, data storage；SDRAM memory is connected with primary processor by by primary processor decoding
Switched between the audio that DTMB program audios and the Big Dipper/GPS dual-mode are called out the stops, frequency switch circuit is connected use with master controller
In control voice-grade channel switching；The audio signal received is amplified and is transferred to outside loudspeaker by power amplifier, so as to realize
DTMB ad systems and the Big Dipper/GPS dual-mode reporting station system share a set of loudspeaker；Infrared remote control is received and is connected with primary processor, is connect
Receive the outside relevant control such as infrared signal, tune platform, tuning for TV programme；Display receives the CVBS of primary processor output
Signal carries out image and shown, installed in the surface in passageway, primary processor receives the Big Dipper/GPS pairs by RS232 communications protocol
Mould is called out the stops information, information superposition will be called out the stops into DTMB graphic programs by image procossing, so as to realize that passenger watches that DTMB is wide
Information of calling out the stops is directly viewable while accusing program；The Big Dipper/GPS dual-mode terminal of calling out the stops is led to by 4G and background server
Letter, the scheduling and job instruction that receiving platform issues, location information is received by the Big Dipper/GPS dual-mode antenna, and with it is built-in
Website latitude and longitude information carries out matching primitives and goes out site name, and primary processor is transferred to by RS232 communications protocol, while built-in
High-quality TTS automatic information broadcasts, it is simple in construction, it is easy to use.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
