The skilled supervisor can instruct the management worker M to move to a position where another system component device 5 related to the system component device 5 is arranged. Based on the current state of the plurality of system components 5, the skilled monitoring person sends an appropriate operation to the management system M to the plurality of system components 5 or one of the plurality of system components 5. Can be instructed. The route in which the management worker M can move from one system component device 5 to another system component device 5 is transmitted from the management center 2 to the device-related computer 11 as map information. The data is transmitted from the participating computer 11 to the display 16 and displayed on the display 16 in a three-dimensional manner. The display 16 can visualize the operation procedure of the system component device 5. As an operation point, a closing method and a closing amount of the valve are exemplified. The manual operation of the management worker M is reported to the management center 2 in real time via the CCD camera 15, and the improper operation can be corrected substantially in real time by a skilled supervisor of the management center 2.
[0033]
The management worker M does not need to bring the equipment operation manual, the equipment layout drawing, and the status report, and does not hold the TV camera in his hand, but passes through the safety route to the location of the monitored equipment in a short time. You can get there.
[0034]
The skilled supervisor of the management center 2 rushes the management worker M to a position where there is equipment that cannot be remotely controlled or communication is interrupted from the data transmitter 29 of the system component equipment 5 which is various in number. Can be properly determined, and the management worker M can be instructed to perform an appropriate operation on the system component device 5 in which remote distributed control is disabled. The management center 2 appropriately removes the management worker M from the danger area based on information (eg, dioxin generation amount, radiation amount, explosive gas leakage amount) received from the system components 5 that are operating normally. Can be evacuated. The location of the system component device 5 to which the management worker M is instructed to express can be known through the display 16, and the system configuration of the operable position where the system component device 5 to be operated and the management worker M have actually approached is located. Since the matching of the devices 5 can be confirmed by reading the ID 22 of the ID tag 19 of the system components 5 by the ID reader 18, the system components 5 to be not operated are not erroneously operated.
[0035]
