Problems solved by technology

This brings about a problem. Some disaster-occurring areas are usually only in a small area and belong to a certain subordinate unit, while the command planes of other subordinate units are idle at this time, resulting in a waste of Beidou command plane resources.

Abstract

A disaster area transmission system based on Beidou short message communication belongs to the field of Beidou communication technology. The communication method of the present invention is Beidou satellite communication, and the communication range can cover areas that cannot be covered by ordinary communication facilities or areas where disasters occur; the present invention The 3D GIS system is used to collect the point sets of disaster occurrence areas, and the collected point set data is compressed by using a new storage method, the data volume is nearly half compressed, and the Beidou transmission bandwidth is effectively saved; the present invention uses the C / S architecture to The network management of the Beidou command plane enables the command planes in the network to work together in emergency situations such as disasters, effectively utilizes the existing command plane resources, and improves the communication success rate between the Beidou command plane and the Beidou terminal; The invention subpackages and repackages control of disaster area point sets with a large amount of data, which solves the problem of a small amount of data transmitted by Beidou short messages at one time.

Description

technical field [0001] The invention relates to the technical field of Beidou communication, in particular to a disaster area transmission system based on Beidou short messages. Background technique [0002] With the improvement of communication technology, the communication network gradually covers most areas of the country. In the case of smooth communication, all kinds of data can be conveyed to the destination in time. However, there are still a large number of areas in my country that cannot be covered by ordinary communication equipment (such as certain mountainous areas or areas where natural disasters such as earthquakes and landslides occur). In response to disasters such as earthquakes, landslides, and forest fires, the staff involved in the first-line rescue are still faced with the situation that secondary disasters occur near the work area without knowing it. In this way, the frontline staff may continue to work without being able to control the overall situat...
