METHOD FOR SELECTING ONE OF PLURAL ELECTRONIC MODULES IN FIELD OF TERMINAL VAGINA

摘要

PURPOSE: A method for selecting one of at least two electric modules capable of simultaneously outputting messages is provided to achieve rapid and easy selection and select imperfectly synchronized modules. CONSTITUTION: The method comprises the steps of transmitting a general query message(ACTIVALL) to modules(M1, M2, M3) designed to determine random time gap(P) when the query message(ACTIVALL, ACTIV) is received and transmit reply message(ID, R) when the time gap(P) elapses, selecting a first-replied module, and designating a first-unreplied modules as an idol state.
