INTEGRATED TIMING SYSTEM AND METHOD HAVING A HIGHLY PORTABLE RFID TAG READER WITH GPS LOCATION DETERMINATION

摘要

A system and method for determining a time of an event participant passing a detection point having a participant identifier number by a proximity detector at a detection point, a highly portable device with a transceiver and a location detector for selectively receiving a participant number read, and determining a location of the portable device, and a timing system having the geographic location of the proximity detector, receiving the geographic location of the handheld device, the handheld read participant number and a handheld determined time, determining that the timing system has not received a usable tag read time from the proximity detector and determining a time of passing of the participant by the detection point by determining a delta time between the proximity detector and the handheld device and an adjusted time of participant passing based on the determined delta time and handheld determined time.

1. A handheld system for supporting an integrated timing system including the determination of a time of a passing at a monitored detection point by a participant in an event having a participant identifier with an associated unique participant identifier number, the system comprising:
a participant proximity detector having a processor, a memory, a clock, a participant identifier detector transceiver receiving the participant identifier number from the participant identifier, identifying a tag read time of the received participant identifier read, and a data interface for transmitting the participant identifier number and the identified participant identifier read time; a handheld device having a processor, a memory, a clock, a user interface, a communication interface, a location detection device for determining a geographic location of the handheld device, and a participant identifier detector transceiver for selectively reading the participant identifier and receiving the participant identifier number from the participant identifier, determining a time of receipt of the participant identifier number by the handheld, and transmitting the determined geographic location of the handheld device, the handheld read tag number and the handheld determined time over the communication interface; and a timing system having a processor, a communication interface, and a memory storing a location for the participant proximity detector, the timing system receiving the geographic location of the handheld device, receive the handheld read tag number and the handheld determined time, determine that the timing system has not received a usable tag read time from the participant proximity detector for the same participant identifier number as the handheld read tag number, determining a delta time as from the difference in the location of the GPS tag reader and the location of the handheld device, calculate an adjusted time for the participant identifier number from the handheld determined time and the calculated delta time, and store the calculated adjusted time as a time of passing of the detection point for the participant identifier number.
