IoT (internet of things)-based automatic refereeing platform for javelin and use method

Abstract

The invention discloses an automatic referee platform for javelin competition based on the Internet of Things. The javelin module I is responsible for sending the flying javelin landing signal to the server module III after the javelin has landed and stopped, and sending a landing induction signal to the field module II. etc.; the field module II is responsible for sending the javelin landing position signal to the server module III after the flying javelin stops on the playing field; the server module III is responsible for receiving the signals sent by the javelin module I and the field module II, and judging whether the javelin head is Correctly inserted into the field, calculate the flying distance of the thrown javelin, and the ranking of all players in the javelin throwing competition; the present invention can automatically and correctly judge whether the flying javelin is correctly inserted into the legal field range, and automatically judge the flying distance of the javelin, thereby avoiding The referee must go to the competition venue to bring personal danger; the competition results of all players are automatically ranked to improve the efficiency of the competition.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an automatic referee platform for a javelin match based on the Internet of Things and a method for using it. Background technique [0002] Track and field competition is one of the ways for modern people to maintain their health, but all competitions must be premised on safety. Wherein the javelin competition, due to the long flight distance of the equipment during the competition, and the relatively sharp head of the javelin, brings certain danger to the referee of the competition. [0003] At present, the Internet of Things technology has made great progress. The development of the Internet of Things technology can not only identify all items, but also use this identification to identify the geographical location of these items. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of using manual flag referees in the ja...

AI Technical Summary

Problems solved by technology

This platform can overcome the existing javelin competition - the referee has to go to the venue to plant the flag. It is proposed to install sensors on the head of the javelin and the venue respectively. The sensor of the field combines the position of the referee's javelin to land, so as to judge the distance of the athlete throwing the javelin this time, avoiding the problem that the referee may accidentally injure the referee during the javelin flight process by personally going to the competition field to plant the flag
