基于北斗三号短报文的应急图文信息传输技术
The transmission technology of emergency graphics and text based on BeiDou-3 short message
摘要
Abstract
In order to improve the capacity of emergency rescue services,an emergency graphic infor-mation transmission technology based on BeiDou-3 short message was studied,and an emergency graphic information transmission platform based on BeiDou-3 was designed.In order to improve the ef-ficiency of BeiDou short message information transmission,text and image compression coding algo-rithms were studied respectively,and the text and image information were compressed into packets with smaller information capacity,which reduced the length of packets required for information trans-mission.The experimental results show that the compression rate of the algorithm reaches 50%for text messages and 2%for image messages.The test results of the platform show that the information interac-tion between the terminal and the commanding machine can be carried out efficiently with limited com-munication resources,which helps to respond to the emergency situation more quickly.The research re-sults have a certain reference value for the emergency management department to improve the capacity of emergency rescue services.关键词
