Abstract

The invention relates to the field of wireless communication, and discloses a distributed asynchronous positioning system and method based on an ultra-wide band. According to the invention, the system comprises at least one beacon and at least one tag. The beacons are independent mutually, and the arrangement positions of the beacons are fixed. Moreover, the coordinates of the positions are known for all tags. When the positions of the tags need to be obtained, the tags transmit range-finding requests, and employ a three-direction range-finding algorithm to obtain the distances from the tags to the beacons after the beacon responses are obtained in a signal coverage. When the tags obtain the distance from the tags to at least one beacon, the tags calculate and obtain the positions of the tags. According to the embodiment of the invention, the system achieves the positioning modes of a user side, a network side and a third side at the same time, and system devices do not need to coordinate with each other in advance and are completely independent mutually. Moreover, the arrangement of the equipment devices is not limited.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a distributed asynchronous positioning technology based on ultra-wideband. Background technique [0002] As early as the 15th century, when humans began to explore the ocean, positioning technology was also born. The main positioning method at that time was to use the nautical charts and astrological charts at that time to determine one's own position. With the continuous development of society and technology, the demand for positioning is not limited to the traditional fields of navigation, aviation, aerospace and surveying and mapping. The positioning method has undergone years of development, from a few systems with poor precision and large equipment in the early stage to the coexistence of multiple positioning methods, and has achieved qualitative leaps in terms of technical means, positioning accuracy, and usability.
