See also Fig. 3.Form electronically by Figure 24, broadcast items database and train playback equipment operational management database 25 by satellite transceiver terminal 21, Global Link mobile data communication terminal 22, the automatic playing device 23 of program, train operation for railway TV platform central authorities broadcasting centre 2.Global Link mobile data terminal 22 receives the train operation track that is sent by the global positioning satellite terminal (GPS) on the train in real time, the automatic playing device 23 of program is according to train electronics operation ground Figure 24, data with reference to broadcast items database 25, by Global Link mobile data communication terminal 22 to just sending various broadcast orders at the automatic playback equipment of operating train TV, and deposit its content of operation in corresponding operational management database 25, in order to start with switch train digital broadcast machine in different programs, the train playback equipment also can some data that need safeguard send to broadcasting centre by GPS with it simultaneously, broadcasting centre deposits it in corresponding playback equipment runtime database, and sends corresponding maintenance instruction by Global Link mobile data communication terminal 22 to the train playback equipment.Satellite transceiver terminal 21 transmits repeater station 4 with program quasi real time and carries out both-way communication, can aim at real time programme and append temporarily, change by the mode of wireless data transmission.
See also Fig. 4.The automatic playback equipment 3 of train TV is made up of the graphic display terminal 39 of car antenna matrix 30, global positioning satellite terminal (GPS) 31, Global Link mobile data communication terminal 32, high-speed radio receiving terminal 33, presentation controller 36, Play System database 34, interim program loading interface 35, automatic digital broadcast machine 37, visual modulator 38, some.
Car antenna matrix 30 and GPS31, Global Link mobile data communication terminal 32, real time programme high-speed radio receiving terminal 33 connects, GPS31, Global Link mobile data communication terminal 32, real time programme high-speed radio receiving terminal 33 is connected with presentation controller 36, presentation controller 36 and Play System database 34, interim program loading interface 35, digital broadcast machine 37 connects, the output of digital broadcast machine connects each graphic display terminal through the closed-circuit television transmission network again after the visual modulator modulation, GPS31, Global Link mobile data communication terminal 22 communications of Global Link mobile data communication terminal 32 and broadcasting centre, real time programme high-speed radio receiving terminal 33 receive quasi real time, and program transmits the program that repeater station 4 sends.
Presentation controller 36 and digital broadcast machine 37 also available computers constitute.The closed-circuit television transmission network can be the two way catv transmission network.
Digital broadcast machine 37 can be installed (storage) programme content of 10 to 80 hours according to the demand of running route.Presentation controller 36 is when receiving GPS31 and Global Link mobile data communication terminal 32 data, form many input variables with clock, interim manual intervention etc., determine the content of broadcast items by intellectualized algorithm, realize functions such as string is broadcast, all kinds ofly intercutted, loop play, the real biography of broadcasting studio video camera; And by interim program loading interface 35, all or part of at any time renewal programme content.The various service datas of the automatic playback equipment of train TV send to railway TV platform central authorities broadcasting centre 2 by Global Link mobile data terminal 32, deposit above-mentioned various data 25 appendix of in train playback equipment operational management database.
Quasi real time program transmits repeater station 4 and is arranged on some large-scale stations, it is made up of satellite data communication terminal, wireless high-speed transponder etc., satellite data communication terminal and broadcasting centre 2 carry out both-way communication, and the program that the satellite data communication terminal receives transmits to the automatic playback equipment 3 of train TV through the wireless high-speed transponder.The satellite data communication terminal is that bi-directional data transmits terminal, all exchanging program and other application data mutually between each repeater station and the central broadcasting centre.The wireless high-speed transponder adopts micropower omnidirectional's microwave or laser modulation technique, and programme content is loaded on low cruise or the static train fast.Like this, a news program of 30 minutes can be finished transmission in 5 minutes, thereby realization news hookup constant pitch purpose is quasi real time play.
The present invention with the advanced person's of the world today computer technology, satellite positioning tech, data communication technology, The technological synthesis of high-speed radio rapid loading applies to long-range unified Broadcast Control, the program of train TV and automatically plays With the interim rapid loading of real-time television program be the outstanding feature of this system schema. Its advantage is:
1. long-range Broadcast Control. Railway TV platform central authorities broadcasting centre is by the Global Link mobile data communication network, no Only can understand the running orbit of train, and can implement the train TV programme adjustment, change, face The time the long-range Broadcast Control such as program loading. After long-range Broadcast Control instruction is sent, the reception condition on the train and execution knot Really, still can in time feed back by the Global Link data communication network.
2. automatically play. Automatic playback equipment on the train relies on the Play Control in the presentation controller soft Part both can be broadcast automatically by the scheduled program table, also can transport according to the train that the global positioning satellite terminal provides Train television program transmission table is adjusted, is changed in the instruction of row track or railway TV platform central authorities broadcasting centre With real time programmes such as interim loading news, special instructions, thereby realize TV programme automatically broadcast and broadcast The unattended function of equipment.
3. wireless rapid loading. Utilize satellite communication terminal, wireless high-speed transponder, adopt micropower complete Load, change program to microwave or laser modulation technique, high-speed radio, realize news hookup constant pitch purpose Quasi real time play.
4. player adopts DVD, SVCD, VCD complete compatible storage, broadcasting format, makes TV Program source is abundanter, and image effect is more clear.
Because program making, the forwarding of native system, number is all adopted in the transmission of various control signals and state Word, because the real-time transmission data of train Play System is seldom, thus if a little expansion, can be real Now to functions such as the location of dynamic train and other management, observing and controlling.
For vehicle-mounted part, the construction of two way catv transmission network, make full train possessed one two-way The transmission of data passage like this, can be realized very easily the various monitoring to railway car, and can will have Close data and send ground command center to, as: antitheft, the SOS of fire alarm, LCD TV, Temperature in the compartment etc. also can arrange TV monitoring and controlling according to demand, can also expand train inner wired and Wireless microcellulor mobile phone.
