Description
Technical field
The invention belongs to government weather early warning and issue System Construction field, particularly relate to a kind of multimedia issue terminal based on the early warning information sending and receiving of CAMEL Application Part (Common Alerting Protocol, public alarm protocol) standard.
Background technology
Nowadays, there is varied, perplexing public alarming mechanism.Except this locality siren and hold except the police of bullhorn, the transport vehicles such as broadcast, TV, phone, outdoor electronic display screen and Invention service provider implement different disasters and the public warning technology of emergency separately.If neither one is to the common description of major event, from the warning information of different medium, confusion reigned is lowered efficiency.Coordinating warning technology is an international significant challenge, and some countries are also making great efforts to coordinate inner segregation of duties.The warning information of bad weather, fire, earthquake, tsunami, disease, internal unrest and other many different disaster is far different, and this exacerbates the complex nature of the problem further.
The angle of investing from public alarm is considered, for often kind of threat, it is nonsensical that society all builds a kind of not coordinated public warning system.The public alarm strategy of a standard, full medium, full Disasters Type more effectively can utilize fund and improve the efficiency of public alarm.Such strategy is not only significant for needing for the public provides the government department of alarm, for various Information technology providers and common carrier, is also significant.
Overwhelming majority information and communicate wired with wireless provider to digital technology transition.This makes them can provide the business of integration, broadcast, TV and mobile phone, satellite phone and the multiple business based on the Internet and other digital network is combined.These communication business provider can easily pass through wired or wireless mode, are supported in these and integrate the warning information sending full Disasters Type in the communication technology, but need the standard of warning information content and process.
The content of full Disasters Type warning information is standardized, and its standardized mode considers the various communication technology.The distribution of CAP information more on a large scale, more eurypalynous alarm and more technology kind are implemented.The system come into operation shows that single, a credible and secure warning information can start internet information fast, news report, television text intercut, the voice messaging of highway signs information and automatic telephone call and radio broadcasting synthesis.The existing country for multiple threats such as bad weather, earthquake and volcanoes and international CAP alarm.
For the administrative staff of emergency, another benefit of CAP is that the standardization critical alarm being derived from various channel can the form of form or chart be edited, auxiliary as situation information and mode detection.When a large amount of adopt CAP time, administrative staff can monitor the overall situation of local, region of any moment or national various alarm.CAP warning information can be used as a kind of form directly to center report dependent event, for sensing system, so that the use of Collection and analysis.
CAP is a kind of breakthrough standard, for new warning system and technological innovation open gate.As a kind of new Information issued pattern, CAP early warning information based on terminal equipment is issued as core research Emergent Public Events early warning information release model and function, 3G network is utilized to carry out information transmission, realize Emergent Public Events early warning information being issued towards all kinds of pre-alarming issuing terminal and browsing, 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 urgent early warning of various network exchange disasters and public pre-warning information.CAP can issue same early warning information by multiple different early warning system simultaneously, thus improves early warning information validity, simplifies early warning task.
CAP standard definition one is called the Doctype of 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 the issue of early warning at present means mainly contain TV station, website, note, LCD liquid crystal display screen, electronic display etc., but in this Information issued the most timely and effectively of LCD liquid crystal display screen means, also mainly based on newly-built.Due to fund restriction, coverage rate is extensive not enough, and the coverage rate of early warning information also cannot reach requirement.For this phenomenon, utilizing the existing issue terminal built to carry out early warning information issue, is means fast and effectively.In addition, issue the requirement of specification according to national Emergent Public Events early warning information, early warning information according to CAMEL Application Part, and on receiving terminal, is not also applicable to the terminal equipment of CAP code requirement at present.Therefore can the CAP information of subscription criteria, and integrate existing LCD multimedia system and carry out early warning information and issue and be even more important.
The utility model patent document of application number CN200720190099.1 discloses a kind of pre-alarm information distribution terminal, comprise shell, power supply unit, video processing unit, audio treatment unit, voice broadcast service unit, display unit, wireless data transmission unit, Terminal Control Element, it can realize the daily weather forecast of sending and receiving, emergency information, early warning signal, value-added information various information hommization subregion is presented at each subregion effectively.But, this patent documentation can only receive and dispatch GRPS or GSM information, and the multiple transmission meanss such as 3G/WIFI/LAN can not be supported, and do not follow CAMEL Application Part standard, interconnecting of message cannot be accomplished, the most important thing is that this patent is exclusive formula to outlet terminal, the delivery system resource of having built cannot be utilized, so that its scope of application is had a greatly reduced quality.
Summary of the invention
