Early warning emergency linkage mechanism implementation frame based on CAP (Common Alerting protocol)

Abstract

The invention discloses an early warming emergency linkage mechanism implementation frame based on a CAP (Common Alerting protocol), which provides supports of system communication, data exchange and information aggregation based on distributed multi-channel early warning information issuing. On the base of CAP1.0 (Common Alerting protocol 01), the frame defines a data exchange format, a data communication encryption and decryption mode and a data collection and aggregation mode, provides conversion support for multiple early warning information content formats by adopting a converged communication gateway technology and realizes automatic conversion of information formats required by multiple issuing channels; due to adoption of a message queue technology, all information can be safely and reliably transmitted, and information issuing and monitoring measures can be provided. The usability, the monitorability and the manageability of all parts of an emergency linkage platform can be ensured trough a tcp / ip long connection mode; the communication security is guaranteed through a digital certificate encryption and decryption mode. The frame provides early warning support guarantee for weather, earthquake, public health and various other emergent events.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a framework for realizing an early warning and emergency linkage mechanism based on the CAP protocol. Background technique [0002] Responding to and handling various types of public emergencies is a cross-business, cross-regional, wide-ranging, comprehensive, multi-level and multi-disciplinary systematic project. The collection and release of early warning information of public emergencies is a key link in the emergency management operation mechanism, which directly affects the emergency response of governments at all levels and departments to public emergencies. When an emergency occurs, if there is no emergency mechanism, no smooth information channels, and no measures to maintain public order, it will lead to rumors, social and psychological panic, social order chaos, and even some lawbreakers will take the opportunity to violate the law. criminal activities. For examp...

AI Technical Summary

Problems solved by technology

[0003] At present, Guangdong Province has not established a unified platform for releasing early warning information of public emergencies in the whole province. Although the release of emergency early warning information in Guangdong Province has achieved certain results, various public early warnings have been initially established in various parts of the province for various public emergencies. The information dissemination system includes mobile phone short message service, fixed telephone service, rural loudspeaker subsystem, electronic display subsystem, and public weather TV channel. Failure to integrate resources well and solve the problem of seamless coverage of information will inevitably affect the quality and efficiency of releasing public emergency warning information to the whole society
