Meteorological disaster early warning information publishing system and method on basis of Beidou satellite

Abstract

The invention discloses a meteorological disaster early warning information publishing system and a meteorological disaster early warning information publishing method on the basis of a Beidou satellite. The early warning information publishing system comprises an early warning information publishing platform, a Beidou short message communication publishing terminal, a short message processing module, a monitoring module, an area identification module, a Beidou early warning information publishing module and a special receiving terminal for the Beidou satellite. The early warning information publishing system has the advantages of small volume, low power consumption and high real-time performance. In the early warning information publishing method, the short message processing module carries out preprocessing on a Beidou short message to obtain early warning information to be published; the monitoring module monitors position information of the special receiving terminal for the Beidou satellite; and the Beidou early warning information publishing module publishes the early warning information according to the position information. According to the meteorological disaster early warning information publishing system and method on basis of Beidou satellite provided by the invention, sub data packets are subjected to self-adaptive grouping preprocessing, so that the flexibility of transmitting the early warning information is improved; and due to the adoption of dynamic encoding, the defect that a code tree does not meet the length condition of the minimum weighted path due to the change of symbolic coding is avoided; and due to the utilization of a pocket supplementing flow and a pocket query flow, the error detection function of the service early warning information data transmission is increased.

Description

technical field [0001] The invention discloses a weather disaster early warning information publishing system and method based on Beidou satellites, belonging to the field of information technology processing. Background technique [0002] In response to the increasingly severe and complex early warning situation of various disasters, although the overall level and capabilities of my country's early warning information system have been greatly improved, there are still the following main problems: the collection, release, and reception of early warning information are not standardized enough to realize various disasters. Information system interconnection and information sharing; information coverage is limited, and the "last mile" problem of early warning information distribution channels has not been resolved, especially the services for rural and vulnerable groups need to be strengthened urgently. [0003] Under harsh environmental conditions, special emergency situations,...
