<p>PURPOSE:To prevent misoperation, an unintended data input and the malfunctional control of a plant and the like due to the unintended data input by registering and storing an operator and an input content and excluding the input of data excepting the registered operator and the kind of operation. CONSTITUTION:At the start of the work by an operation command, data on the operator and the kind of the operation are originated from a data registration/origination equipment which the operator in charge carries, and a registration data discrimination device 6 receives and discriminates data, whereby they are inputted to a command selection/permission device 4. Thus, the operation command is executed only for the kind of the operation registered in the data registration/origination equipment 5 which the operator carries. Since items out of registration cannot be operated and data on the operator and the operation content are recorded, control of recognition and the like can be executed later. Furthermore, the input by the accidental misoperation as to the operation and an equipment can be prevented.</p> |
