Description
Technical field
The present invention is applicable to emergent broadcast, belong to digital communicating field, the method and the device thereof that relate to the emergency broadcase system rapid deployment relate in particular to a kind of emergent broadcast communication system construction method and device that utilizes the digital broadcasting technology to send information and control the automatic broadcast of receiving terminal.
Background technology
Large-scale natural calamity may cause existing electric power, communication system badly damaged, and even paralysis is such as earthquake, tsunami etc. often can be with aftershock, heavy rains etc.In order to reduce disaster to the loss that the people cause as far as possible, stablize victims of the disaster's mood, after calamity, 72 hours rescue golden periods are particularly important.In the situation that after calamity, electric power and communication equipment interrupt, we need a kind of can Rapid Establishment, reliable, believable means of communication.
Mostly connect by wire mediums such as optical fiber, coaxial cables from county level being broadcast between each town's level broadcasting.These connection lines are probably damaged in large-scale natural calamity, but the damage degree in each small towns village may be different, can not play equally higher level's the condition of a disaster notice and indication in the complete situation of the circuit in part small towns self and equipment.So we should utilize as far as possible existing equipment to be connected equipment with connection and set up effective means of communication.
At present, government generally uses modes such as radio diffusion van that typhon is installed to assemble the place such as ground, rescue ground the victims of the disaster to carry out the broadcast publicity the condition of a disaster and reassure the public.But there is comparatively outstanding limitation in present above-mentioned solution:
1) broadcasting area is limited: the limited coverage area of the typhon on radio diffusion van is no more than several kilometers, also needs the direct transmission of information of person to person.
2) real-time is poor: the radio diffusion van flowing time is long, and the whole notices of a mobile ability put in place informational needs in whole section first.
3) complicated operation: when issuing new notice, the system of various places radio diffusion van is inconsistent at every turn, can't receive in real time the documentary whip of disaster relief centers, and timely broadcast announcement.
Summary of the invention
For overcoming the shortcoming of prior art, the present invention has aimed to provide a kind of emergency broadcase system based on digital broadcasting, this emergency broadcase system can utilize existing broadcasting equipment as far as possible, in case of emergency can be from the control of dynamic response disaster relief centers, open the various places broadcast system, realize covering the broadcast system that unified command is controlled comprehensively.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of emergency broadcase system based on digital broadcasting, comprise emergent broadcast launching centre, emergent broadcast receiving terminal and emergent broadcast Play System, described emergent broadcast receiving terminal receives the content from described emergent broadcast launching centre emission, broadcasts away by described emergent broadcast Play System;
