FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering. The method of resolving a conflict in accessing a conflict-free messaging device (CFMD), which employs a CFMD and numbered objects which transmit to and receive from the CFMD optical signals via a separate wireless link for each object at three possible frequencies, wherein the signal at the first frequency is pulsed and is used by the objects to determine the time of propagation of the signal from the object to the CFMD, the signal at the second frequency is pulsed, has one of four durations ν, ρ, σ, τ, linked by the relationship 3ν<σ<ρ<τ and is transmitted simultaneously only by one of the objects, the signal at the third frequency is constant, is transmitted by to the CFMD by the objects and is returned to said objects by the CFMD with temporary interruption of the reception by the CFMD of the signal at the second frequency from the object, wherein the CFMD counts the time interrupted and resuming upon the arrival of the signal at the second frequency, or upon achieving a predetermined time value.
EFFECT: high speed of resolving access conflicts.
