Preferably, the escape way of connection one-level distribution module and secondary distribution module is Local Area Fiber net or encrypts VPN passage.
Preferably, between each receiving terminal and secondary distribution module, be also provided with the second connecting path, this second connecting path is IP network, for example, be VPN network.
Preferably, this second connecting path is mobile radio communication, and this secondary distribution module and receiving terminal are equipped with to be encrypted and deciphering module, the information that secondary distribution module is fed back to secondary distribution module by mobile radio communication to receiving terminal and receiving terminal is encrypted and deciphers.
Preferably, one-level is connected with secondary distribution module with one-level respectively by encrypting VPN passage with control of authority module with secondary editor.
Preferably, this information distribution system also corresponding one-level distribution module and secondary distribution module is respectively equipped with backup module, respectively the information of one-level and secondary distribution module is backed up.
Preferably, this information distribution system is also provided with the 3rd connecting path between receiving terminal and one-level distribution module.
Compared with prior art, the present invention is multistage by information distribution system is divided into, so effectively share the load of one-level distribution module, the advantage of the abundant radio network broad covered area of the present invention simultaneously, thereby make the quantity of receiving terminal unrestricted, in signal coverage areas, a lot of receiving terminals can be set, therefore when terminal quantity is large, operation cost can maintain in relatively low level, the bandwidth of data channel is constant simultaneously, thereby guarantee data are effectively transmitted.
Accompanying drawing explanation
Fig. 1 is for implementing the system architecture diagram of information distribution system of the present invention.
Embodiment
Please refer to shown in Fig. 1, for implementing the system architecture diagram of information distribution system of the present invention, this information distribution system comprises:
One-level editor and control of authority module 100, the information that level-1 area (as overall region) is sent is edited, and the authority of using and access receiving terminal 300 is controlled;
One-level distribution module 101, is connected with control of authority module with one-level editor, and the distribution of information of editing in order to one-level editor and control of authority module is to the distribution module of subordinate;
Secondary editor and control of authority module 200, edit the newly-increased information of level-2 area (as regional area), and the authority of using and access controlled;
Secondary distribution module 201, is provided with a plurality ofly, receives the content of one-level editor and the output of control of authority module, and integrates secondary editor and export afterwards with the content of control of authority module 200 outputs;
Broadcast signal transmission module 202, corresponding each secondary distribution module 201, receives the content of secondary distribution module 201 outputs, and exports by the mode of broadcast singal;
Receiving terminal 300, corresponding each broadcast signal transmission module 202 can be provided with a plurality of receiving terminals, the broadcast singal of receiving broadcast signal transmitter module 202 outputs.
In the above embodiment, secondary distribution module 201 is to be connected with one-level distribution module 101 by escape way, and in order to receive the information of one-level distribution module 101 outputs, in the specific implementation, this escape way can be the VPN passage of Local Area Fiber net or encryption.
In the specific implementation, between each receiving terminal 300 and secondary distribution module 201, be also provided with the second connecting path 301, this second connecting path 301 can be I P net, special VPN network, or this second connecting path 301 is also mobile radio communication, and this secondary distribution module 201 and receiving terminal 300 are equipped with to be encrypted and deciphering module (not shown), the information that secondary distribution module 201 is fed back to secondary distribution module 201 by mobile radio communication to receiving terminal 300 and receiving terminal 300 is encrypted and deciphers, so can increase the fail safe of information, prevent potential network security attack.When practical application, this second connecting path 301 and broadcast singal path (be broadcast signal transmission module 202 with receiving terminal 300 between broadcast connecting path) coordinate and carry out transfer of data, particularly utilize broadcast singal path broad covered area, advantage that cost is low to realize the transmission of mass data, and can utilize the second connecting path 301 supplement some data that receiving terminal 300 do not receive and feed back some signals, thereby reduce downlink data amount, to realize transfer of data cheaply.
Meanwhile, one-level editor is connected with secondary distribution module 201 with one-level distribution module 101 respectively by VPN passage with control of authority module 200 with secondary editor with control of authority module 100, also can increase the fail safe of information.
