Method of applying rfid in ball game field/court to assist referee in making a decision and system therefor

Abstract

A system for applying RFID in ball game field to assist in making a decision in ball game includes a RFID tagging element embedded in a ball used in the game; a plurality of RFID reading devices spaced along borderlines of the ball game field for reading the RFID tagging element in the ball; and a control center connected to the RFID reading devices. When the ball with embedded RFID tagging element touches any of the borderlines, at least one of the RFID reading devices reads the RFID tagging element and sends a signal to the control center for determining whether the ball is out of bound or not. When the RFID reading devices are arranged at goal areas, the system may be used to determine the scoring. A decision signal is sent from the control center to a referee for use as a reference in making a decision.

1 . A system for applying RFID in a ball game field/court to assist a referee in making a decision in a ball game, comprising:
 at least one RFID tagging element embedded in a ball;   at least one RFID reading device arranged in decisive areas on the ball game field/court; the RFID reading device being adapted to sense and read the RFID tagging element;   a control center connected to the at least one RFID reading device for receiving, computing, and processing a sensing signal transmitted from the at least one RFID reading device, so as to generate a decision signal; and   a receiving device for receiving the decision signal generated by and transmitted from the control center.   
   
   
       2 . The system as claimed in  claim 1 , wherein the receiving device includes a signal receiving receiver for receiving the decision signal transmitted from the control center, a power unit, a microprocessing unit for processing the decision signal received by the signal receiver, and at least one signal display unit, on which data obtained from the decision signal processed by the microprocessing unit is shown. 
   
   
       3 . A method of applying RFID in a ball game field/court to assist a referee in making a decision in a ball game, comprising the steps of:
 (a) arranging a plurality of RFID reading devices in all decisive areas in the ball game field/court to define at the decisive areas a sensing district each;   (b) one or more of the RFID reading devices transmitting a sensing signal to a control center when a ball with an imbedded RFID tagging element passes one of the sensing districts within a sensing range of that RFID reading devices; and the control center processing the sensing signal received from the RFID reading devices to determine whether the ball has entered the sensing district or not; and   (c) the control center converting data obtained from the processed sensing signal into a decision signal, and sending the decision signal to at least one receiving device for showing the decision signal thereon, so that the referee may use the decision signal as a reference in making a decision in the ball game.
