Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] The present invention mainly utilizes the combination of trilateration positioning method and RSSI distance measurement to determine the exact position of the athlete. The RSSI technology is mainly based on the signal strength value received by the reference node, through the experience or theoretical model formula of the propagation signal, and directly converts it into the reference node The distance value from the mobile node. Theoretically, as the distance increases, ...

Abstract

The invention provides an athlete positioning method and system. The positioning method comprises the following steps of gridding a sports field, and establishing a first rectangular coordinate systemby taking the center point of the sports field as a coordinate origin; selecting a plurality of reference nodes on the sports filed, measuring the RSSI (Received Signal Strength Indicator) value of each grid vertex, and establishing a matching database of the RSSI values of the grid vertexes; determining the values of a radio frequency parameter A and a signal transmission constant n; measuring the RSSI value of a position at which an athlete is positioned in real time, and calculating the distance between the position of the athlete and each reference node; calculating the preliminary coordinates of the athlete; determining grids in which the athlete is positioned based on the preliminary coordinates of the athlete; calculating the distance between the athlete and each grid vertex of thegrids in which the athlete is positioned; and calculating the precise coordinates of the athlete. The positioning system comprises positioning receivers arranged at the reference nodes, a positioningtransmitter mounted on the athlete, and an upper computer. Through the adoption of the athlete positioning method and system provided by the invention, the athlete position can be positioned more accurately.

Description

technical field [0001] The invention relates to the technical field of positioning, in particular to a positioning method and system for athletes. Background technique [0002] In football, basketball and other sports, the running ability of athletes can directly affect the result of the game, so running ability is one of the important basic abilities of athletes, and it is also an important indicator for coaches to assess players . Now the requirements for athletes' running ability and timing judgment are getting higher and higher. The real-time positioning system locates, saves and analyzes the running trajectory of the athlete in real time, and calculates the parameters related to the amount of exercise and consumption of the athlete according to the trajectory. Therefore, real-time positioning plays a key role in sports such as football and basketball. The positioning method adopted in the prior art is not precise enough for the athlete's positioning, and accurate dat...
