<P>PROBLEM TO BE SOLVED: To provide an operation control system improved in security performance by performing the transmission of a key switch and an elevator control device by a transmission signal different from a conduction signal and a non-conduction signal. <P>SOLUTION: This operation control system has a switch unit 10a having a switch for selecting an operation mode, a contact point decoding circuit for generating a decoding signal corresponding to a closed contact point position at each operation mode, a first storage means prestoring a plurality of identification modes and an encoding signal output means for outputting an encoding signal corresponding to an identification code selected from the first storage means on the basis of the decoding signal, a discriminating means 6a having a second storage means prestoring the same identification code as the plurality of identification codes stored in the first storage means and a switching signal output means for outputting a switching signal corresponding to a collated identification code by collating the plurality of identification codes stored in this second storage means with the encoding signal, and a control means 8 for switching an operation mode on the basis of a switching signal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
