PROBLEM TO BE SOLVED: To reliably prevent an erroneous operation of an operation object instrument by false recognition by an operator.SOLUTION: When an operation to designate an instrument 130 to be an operation object (designated instrument 130) is received in an operation device 101, check data about the designated instrument 130 is obtained from among check data stored for each instrument 130. An erroneous operation prevention device 105 generates sound recognition data by analyzing an inputted sound, and when the obtained check data and the sound recognition data are in agreement, enables output of a driving signal to drive and control the designated instrument 130, and when they are not in agreement, limits (blocks) output of the driving signal. |
