Typhoon Emergency Mapping Method Based on Beidou Short Message

Abstract

The invention relates to a typhoon emergency rapid drawing method based on a Beidou short message, and the method comprises the following steps: S1, determining typhoon emergency drawing information, carrying out the identification of a typhoon emergency drawing short message, and extracting a needed minimum information field data set; S2, carrying out the classification of information fields in the data set extracted at step S1 through a typhoon emergency information issuing platform, carrying out decimal text coding to form the Beidou short message, and carrying out the transmission of the Beidou short message through a Beidou communication module in the typhoon emergency information issuing platform and a Beidou communication satellite; S3, receiving the Beidou short message transmitted by the Beidou communication satellite through a typhoon emergency drawing terminal, analyzing the Beidou short message according to a decimal text coding rule, extracting information of drawing elements, and carrying out typhoon emergency drawing and display on a base map template according to the information of drawing elements. The method can iron out the defect of error codes or package loss caused by map compression or blocking, and improves the efficiency of quick drawing under the condition of typhoon emergency.

Description

technical field [0001] The invention relates to the field of information technology processing, in particular to a typhoon emergency quick mapping method based on Beidou short messages. Background technique [0002] Short message communication is a unique function of the Beidou satellite system independently developed by my country. It realizes the communication function of navigation satellites and is suitable for two-way information transmission including location information when the mobile phone signal is interrupted. As an effective supplement to conventional communication, short message communication has been widely used in the fields of atmosphere, ocean, and public safety, such as weather early warning, air defense forecast distribution, and earthquake emergency communication. [0003] Beidou terminals need Beidou cards to perform short message communication and positioning services. There is a unique Beidou ID, and different terminals are identified by different ID ...

AI Technical Summary

Problems solved by technology

[0004] The typhoon emergency message contains information such as typhoon location, time, wind speed, wind direction, wind circle, etc. It is not easy for end users to intuitively grasp the real-time situation of typhoon if only relevant text information is displayed

However, the bandwidth limitation of traditional short-message communication makes it easy to cause bit errors or packet loss if the typhoon emergency map needs to be compressed and sent in blocks, and it also affects the real-time performance of information transmission.
