ANTI-COLLISION METHOD OF A DISTANCE MEASUREMENT SIGNAL USING AN ARBITRATION ALGORITHM, CAPABLE OF MEASURING POSITIONS OF MULTIPLE TARGETS BASED ON TRIANGULATION

摘要

PURPOSE: An anti-collision method of a distance measurement signal is provided to prevent a collision of transmitted signals in case multiple position measurement targets exist in a coordinate calculation of location measurement targets using triangulation when measuring a distance between standard points for calculating a distance between a reference point and the target for position measurement.;CONSTITUTION: A position measurement target generates a self-determined waiting time arbitrarily(S101), reduces the waiting time in a countdown mode(S102) and determines whether the self-determined waiting time expires or not(S103). In case a determination result does not expires, a position measurement target determines whether a position measurement start signal senses from another position measurement target or not(S104). In case a position measurement start signal is not sensed by a determination result, a position measurement target returns again to countdown the waiting time and repetitively countdowns the waiting time or determines whether a position measurement start signal is sensed or not. In case the waiting time is expired by the determination result of the step S103, a position measurement target performs a self position measurement(S106a) after broadcasting a self position measurement start signal(S105a) and broadcasts a position measurement end signal(S107a) after completion.;COPYRIGHT KIPO 2013;[Reference numerals] (S101) Generating a waiting time; (S102) Counting down the waiting time; (S103) Waiting time expired?; (S104) Position measurement start signal sensed?; (S105a) Broadcasting the position measurement start signal; (S105b) Wait; (S106a) Performing position measurement; (S106b) Position measurement end signal sensed?; (S107a) Broadcasting the position measurement end signal;
