Problems solved by technology

[0004] In the field of emergency rescue, using Beidou terminals with Beidou communication functions to send out distress messages can realize emergency rescue for mobile terminal carriers, but Beidou terminals in the prior art cannot communicate with other communication networks except the Beidou communication network contact, which severely limits the rescue targets of the people to be rescued, and reduces the chances of being rescued; in addition, when a group of expedition members separate and disperse in an area not covered by the communication network signal, it is impossible to query the location of nearby teammates in real time. Unable to achieve mutual aid and rescue among expedition members

Embodiment Construction

[0046] For the convenience of illustration and understanding, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] see figure 1 Shown is an emergency rescue method based on Beidou satellite communication according to an embodiment of the present invention, which is characterized in that it includes:

[0048] S101: Create a neighbor reference table containing multiple Beidou IDs that are associated with each other on a server. The neighbor reference table includes historical positioning and rescue information corresponding to multiple Beidou IDs. The positioning rescue information includes Beidou ID, location information, Location time of help information and location information;

[0049] S102: The server receives the positioning rescue information sent by the Beidou terminal, and inquires whether there is a friend-neighbor query request in the received help-seeking information, and if there is a friend-neighb...

Abstract

The invention provides a beidou-satellite-communication-based emergency rescue method. The method comprises: a neighbor reference table including a plurality of beidou IDs associated with each other is established, wherein the neighbor reference table includes historical positioning rescue information corresponding to the plurality of beidou IDs and the positioning rescue information includes the beidou IDs, position information, help information, and positioning time; if a neighbor query request exists in the received help information, beidou IDs that are associated with the received beidou ID and historical positioning rescue information are obtained; according to historical positioning rescue information and the received position information and positioning time, a position offset and a positioning time offset are determined, and if the position offset and the time offset are less than a predetermine threshold value, historical positioning rescue information is determined as a neighbor positioning rescue information; and the neighbor positioning rescue information is fed back to a beidou terminal. in addition, the invention also provides a beidou-satellite-communication-based emergency rescue system, thereby realizing friendly neighborhood and mutual assistance in an area with no coverage of a communication network signal.

Description

technical field [0001] Embodiments of the present invention relate to the field of emergency rescue, and in particular to an emergency rescue method and system based on Beidou satellite communication. Background technique [0002] The Beidou satellite navigation system is a global satellite positioning and communication system developed by China itself [0003] (BDS) is the third mature satellite navigation system after the US Global Positioning System (GPS) and the Russian GLONASS. It can provide high-precision, high-reliability positioning, navigation, and timing services for all kinds of users around the world, all-weather, especially Beidou first-generation communication satellites have short message communication (BeiDou communication) in addition to positioning functions. ability. Among them, the communication function of Beidou satellite is of great significance to the emergency rescue work of natural disasters. For example, in the case of interruption of mobile com...
