Abstract

PURPOSE:To enable an operator to easily and surely select the screens with the voice input over a wide range of a central control room and to grasp instantaneously the plant state in common when the abnormality occurs by setting dispersely the microphones and registering the voice pattern of an operating subject. CONSTITUTION:When an operator wants to select and switch the display screens of a large display device 3, the operator uses the nearest one of microphones set dispersely in a central control room to aurally select the screens. Then the sound signals are converted into the digital spectrum signals by a voice input device 5 and taken into a computer 1. The voices are recognized by the computer software 11 via a voice recognizing/understanding technique. In this case, the ID information on the operator is already recognized and then read out of a voice pattern registered previously in a memory for reference. Thus the information inputted through the microphone 4 and recognized aurally is compared with the voice pattern. Then the contents of the recognized information are decoded when the coincidence is obtained from the comparison. The plant information on the relevant screen and the fixed screen information are displayed and edited on the device 3 based on a screen switching instruction.
