Abstract
A plant monitoring apparatus and a plant operation monitoring method are disclosed, wherein the plant monitoring apparatus includes a display unit for displaying a plant monitor screen having a plurality of windows displayed in superposition with each other, a monitor unit for monitoring a status change of the plant, and a control unit for transparently displaying at least a partial area of the superposed window upon detection of a status change of the plant by the monitor unit.
Claims8
A plant monitoring apparatus comprising:
- a display unit for displaying a plant monitor screen including a plurality of windows in superposed relation with each other;
- a monitor unit for monitoring a status change of a plant;
- and
- a control unit for transparently displaying at least a partial area of the windows displayed in superposed relation with each other on the display unit upon detection of a status change of the plant by the monitor unit.
A plant operation monitoring method for a plant operation monitoring system wherein a plant monitoring apparatus for displaying a plant monitor screen having a plurality of windows displayed in superposed relation with each other and a plant operation monitor supporting device for supporting the monitoring of the plant operation by the plant monitoring apparatus are connected to each other through a network, comprising the steps of:
- the plant monitoring apparatus monitoring the operation of the plant and transmitting the monitor data acquired to the plan operation monitor supporting device;
- the plant operation monitor supporting device receiving the monitor data through the network, simulating the plant operation based on the monitor data received and generating and transmitting the priority information for selected one of each superposed window and each display factor for the superposed display of the plant monitor screen by the plant monitoring apparatus in accordance with the result of the simulation;
- and
- the plant monitoring apparatus receiving the priority information, calculating the priority difference for selected one of each superposed window and each display factor based on the received priority information, and transparently displaying at least a partial area of the superposed window in accordance with the transmittance preset for each priority difference calculated.
