Description

LED display issue terminal based on CAP codes and standards early warning information
Technical field
The invention belongs to government weather warning issue System Construction field, relate in particular to a kind of early warning information sending and receiving LED display issue terminal based on CAMEL Application Part (Common Alerting Protocol, public alarm agreement) standard.
Background technology
Nowadays, exist varied, perplexing public alarming mechanism.Except the siren of this locality with hold the police of bullhorn, the transport vehicles such as broadcasting, TV, phone, outdoor electronic display screen have been implemented different disasters and the public warning technology of emergency separately with Internet service provider.If neither one is to the common description of major event, from the alarm message of different media with confusion reigned and lower efficiency.Coordinating warning technology is an international significant challenge, and some countries are also making great efforts to coordinate inner segregation of duties.Bad weather, fire, earthquake, tsunami, disease, internal unrest are far different with the warning information of other many different disasters, and this has further aggravated the complex nature of the problem.
Consider that from the angle of public alarm investment for every kind of threat, it is nonsensical that society all builds a kind of not coordinated public warning system.The public alarm strategy of a medium standard, complete, full Disasters Type can more effectively be utilized fund and improve the efficient of public alarm.Such strategy for being significant for the public provides the government department of alarm, for various information technology providers and common carrier, also is significant not only.
Overwhelming majority information and communicate by letter wired and wireless provider are to the digital technology transition.The business of integration can be provided like this, the business of broadcasting, TV and mobile phone, satellite phone and multiple Internet-based and other digital network is made up.These communication service providers can be supported in these and integrate the alarm message that sends full Disasters Type in the communication technology easily by wired or wireless mode, but need the standard of alarm message content and processing.
The content of full Disasters Type alarm message is by standardization, and its standardized mode has been considered the various communication technologys.Implemented on more extensive, more eurypalynous alarm of the distribution of public alarm agreement (CAP) message and the more technology kind.The system that has come into operation shows that single, a credible and secure alarm message can start fast that the Internet message, news report, television text are intercutted, highway token message and automatic telephone call and the synthetic sound message of radio broadcasting.Existing country and international CAP alarm for multiple threats such as bad weather, earthquake and volcanoes.
For the administrative staff of emergency, another benefit of CAP is that the standardization critical alarm that is derived from various channels can be edited with the form of form or chart, as assisting of situation information and mode detection.When a large amount of employing CAP, administrative staff can monitor the overall situation of any moment this locality, zone or national various alarms.CAP alarm message can be used as a kind of directly to the form of center report dependent event, is used for sensing system, so that the usefulness of Collection and analysis.
CAP is a kind of breakthrough standard, for the gate has been opened in newly warning system and technological innovation.As a kind of new information release model, CAP early warning information based on terminal equipment is issued as core research Emergent Public Events early warning information release model and function, utilize 3G network to carry out communication, realization is issued the Emergent Public Events early warning information and browse towards all kinds of pre-alarming issuing terminal, develop the CAP information issuing system based on terminal equipment with China's characteristic, must have very broad.
CAP is a kind of standardized XML data format of simplification, is applicable to the diverse network exchange urgent early warning of disaster and public pre-warning information.CAP can issue same early warning information by multiple different early warning system simultaneously, thereby improves early warning information validity, simplifies the early warning task.
The CAP standard definition a kind of Doctype that is called early warning (alert), this document is used for exchanging is permitted many-sided early warning and event, such as meteorology, geology, public health and safety, rescue, law enforcement, environment, communications and transportation, infrastructure and terrorist activity.This early warning can generate by event response department is manual, also can be generated by supervision and sensing equipment monitor message, and early warning issue means mainly contains TV station, website, note, electronic display etc. at present.But on this most timely and effectively information of electronic display issue means, also mainly be as main take newly-built.But because fund limitation, coverage rate is extensive not enough, and the coverage rate of early warning information also can't reach requirement.For this phenomenon, utilize the existing issue terminal of having built to carry out the early warning information issue, be means fast and effectively.In addition, according to the requirement of national Emergent Public Events early warning information issue standard, early warning information is according to public alarm agreement (CAP), and on receiving terminal, also is not fit at present the terminal equipment of CAP code requirement.Therefore can subscribe to the CAP information of standard, and integrate existing electronic display screen system and carry out the early warning information issue and be even more important.
The patent of invention document of application number CN201110354304.4 discloses a kind of cellular prewarning information distribution system, comprise a disaster information release module, one data transmission module and some issue terminals, the disaster information release module sends to data transmission module with early warning information, pass to issue terminal by data transmission module, issue terminal blazes abroad early warning information, data transmission module and issue terminal are provided with wireless frequency modulation, and it is consistent with data transmission module so that data transmission module sends early warning information to some issue terminals formation cellular transmission that issue terminal arranges frequency.But this invention transmission means only limits to cellular transmission, and does not support the multiple transmission meanss such as GRPS/3G/WIFI/LAN.
The utility model patent document of application number CN201120021342.3 discloses a kind of pre-alarm information distribution terminal, comprise communication module, microcomputer, power supply module, described communication module is based on mobile GSM/GPRS unit or UNICOM's cdma network, added the software solidification unit in the described equipment, described software solidification unit links to each other with microcomputer, and described microcomputer arrives remote control computer by network connection.But this invention belongs to the Absolute control terminal, can only be take newly-built as main.Above-mentioned two patent documentations are not all followed the CAMEL Application Part standard, can't utilize existing output equipment to carry out data publish.
Summary of the invention
For described problem, the present invention is based on all kinds of early warning information receiving terminals, the technology such as the computer of application of advanced, the network communications technology, 3G, adopt CAMEL Application Part, realize XML-based standard, the information issue standard of early warning information can be provided, by LED offline e screen and online electrical screen output issue, form final pre-alarm information distribution terminal product.
