5. system can receive and dispatch video file, the broadcast log file that operator edits automatically, and whole document transmission process need not manual intervention.
6. for satisfying the needs that system expands, the present invention is reserved with the interface of interior situation of Detection ﹠ Controling car and equipment, comprise passenger flow, switch door, temperature etc., cough like this, formulate the driving plan for public transit system science, real data are provided to monitor and to grasp the ruuning situation of vehicle more effectively.
The present invention is further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a work system schematic diagram of the present invention.
Fig. 2 is " all-in-one " structure principle chart.
Fig. 3 is " all-in-one " structural representation.
Specific embodiments embodiment is as shown in drawings: novel bus intelligent scheduling mobile communication multimedia audiovisual system is divided into three according to the Network Transmission rank: intelligent terminal, Network Transmission trunking, control terminal.Wherein, intelligent terminal comprises the wireless folding and unfolding of vehicle mounted multimedia, satellite fix, wireless communication system all-in-one (being called for short " all-in-one "), electronic intelligence platform; The Network Transmission trunking comprises station server, telecommunication transmission routing device (router, switch etc.), the video server that is used for medium operations and is used for the gps satellite locating module of intelligent bus dispatching and WCDMA/GSM wireless communication module (above two modules are integrated in " all-in-one "), telecommunications radio transmission apparatus (wireless base station, gateway etc.); Control terminal comprises the video frequency program control centre of operator, the control centre and the public traffic management center, city of each circuit of public transport.Also has application software in addition in the system around these services.Be intelligent public transportation dispatching system transmissions structure more than the dotted line among the figure, dotted line is following to be medium operator Video service transmission structure.
" all-in-one " is made up of cabinet, power supply, mainboard, CPU, hard disk, internal memory, display screen, the cpu motherboard (2) and the MCU mainboard (8) that are installed in the cabinet (16) are coupled to each other by power line (14) and RS232 Serial Port Line, and internal memory (3) and CPU (4) assign on the cpu motherboard (2); Hard disk (5) connects with cpu motherboard (2) by the USB interface holding wire by ide interface holding wire, wireless network card (15), and GPS global positioning satellite module and 3G RFDC module (12) connect with cpu motherboard (2) by data wire; Cpu motherboard (2) connects with loudspeaker (11) on the car through voice decoder (13) by holding wire, and cpu motherboard (2) connects respectively with liquid crystal main display (1) and liquid crystal pair display screen (10) by the VGA holding wire; The switch (9) that also has fan (7) and control flow that links with MCU mainboard (8).By the vehicle-mounted special-purpose stabilized voltage power supply (6) of automobile storage battery power supply, by power line (14) input MCU mainboard (8), cpu motherboard (2), fan (7), liquid crystal main display (1) and the secondary display screen (10) of liquid crystal; The secondary display screen of liquid crystal (10) has single casing, and above-mentioned liquid crystal main display (1) and remaining components and parts all are installed in the cabinet (16).
The intelligent bus dispatching patcher is based on GPS global positioning satellite module and WCDMA/GSM wireless communication module function." all-in-one " receives the GPS locating information by the gps receiver that extends in roof, and these locating information are mainly used in two purposes.One is the latitude and longitude information that collects according in these locating information, and " all-in-one " compares by the bus station latitude and longitude information that is stored in the industrial computer with setting, realizes the automatic broadcasting function according to certain corrected parameter; Another is that " all-in-one " is sent to switching center in the GPRS mode through the telecommunications wireless base station by the WCDMA/GSM wireless communication module with these locating information again, switching center transfers to the dispatching communication software processes of each control centre with this information through wired broadband networks such as ADSL again, and the result of processing finally reflects with the intuitive interface of electronic chart.This has just realized vehicle visual location the most basic in the intelligent bus dispatching.Round this basic function, dispatcher software has derived other a series of functions (vehicle monitoring, vehicle scheduling, station personnel and management of vehicles, station material statistics etc.).Certainly, except the utility model, also having terminal equipment such as electronic intelligence platform also is the intelligentized important component part of city bus.
The video operation service system has very strong economic and practical for the development platform that medium operator provides national advertisement Operation Network.The video information file that medium operator will gather and edit uploads to video server in program control centre by cable broadband, the new file that video server then will be uploaded passes in the station machine of each public transport base station, road down automatically, after in vehicle enters the base station radio local area network (LAN), the utility model that is installed in each bus can be dynamically connected certainly and detect by wireless network card whether new video file renewal is arranged in the machine of station, base station, if there is more new video files will automatically these files be downloaded on the car in the memory of the present utility model, these new programs will be broadcasted by the video jukebox software in the utility model, have only program control centre to need artificial control in this whole link.In addition, because the restriction of existing mobile wireless network transmission bandwidth speed also is because the video file data volume is excessive simultaneously, the transmission on the video is to realize by wired broadband network and WLAN (wireless local area network) at present.But we can imagine, after mobile communication evolves to third generation communications platform in the near future, the mobile wireless data bandwidth can satisfy the demand of video transmission, this just means the transmission that can reach video frequency program by wireless communication module of the present utility model, the station machine of intermediate link and telecommunications cable broadband are incited somebody to action needs no longer, and this system will embody stronger economic benefit.
