Problems solved by technology

However, the above-mentioned method of using mobile vehicles is easily restricted by the terrain structure, and its coverage is also very limited, and it is impossible to achieve all-round coverage
More importantly, the biggest problem with this method is that it is impossible to accurately locate the tracking object (the rescuer or the rescued person), and often "only hear the sound (through communication equipment) but not see the person"
Because of this, it is also difficult for the background command vehicle to carry out rescue deployment effectively

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

[0022] The first embodiment of the present invention relates to an emergency deployment system based on ultra-wideband. Such as figure 1As shown, the emergency positioning system includes several nodes (also called node devices), which are the smallest components of the distributed asynchronous positioning system (DAPS), and all belong to ...

Abstract

The invention relates to the field of communication, and discloses an ultra-wideband based emergency positioning system and a layout method thereof. The emergency positioning system comprises a plurality of beacon nodes and at least one tag node, wherein part of the plurality of beacon nodes are arranged on the periphery of an emergency layout area, and the other part is arranged in the emergency layout area; the beacon nodes arranged on the periphery of the emergency layout area work in a beacon mode during operation; the beacon nodes arranged in the emergency layout area work in a tag mode in the initial phase, and are switched to the beacon mode from the tag mode after determining the own location and detecting that the beacon nodes no longer move; and the tag nodes carried on a target positioning object determine the own location by taking the beacon nodes that work in the beacon mode as reference nodes in the emergency layout area. Compared with the prior art, by adopting the ultra-wideband based emergency positioning system and the layout method thereof disclosed by the embodiment of the invention, an emergency positioning network can be rapidly and flexibly established in the emergency scene, and the accurate positioning of rescue workers can be achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to an ultra-wideband-based emergency positioning system and a deployment method thereof. Background technique [0002] When emergency disasters such as earthquakes and fires occur, rescuers need to enter the scene immediately to carry out rescue. At this time, it is necessary to know the location of the rescuers, that is, to accurately track the rescuers to understand the situation at the disaster site. However, the surface and buildings of the disaster site will generally be severely damaged. Therefore, even if there were communication equipment at the incident site, those communication equipment will be greatly damaged at this time, causing the communication network at the incident site to be paralyzed. , unable to realize the positioning of rescuers. And if the network is re-established step by step on the spot, precious rescue time will be wasted. [0003] In the existing disaster sc...
