Plant state displaying apparatus, plant state displaying system, and method of displaying plant state

A plant state displaying system displaying information representing a state of a plant, the plant state displaying system comprising:

• a server apparatus that:
• acquires plant information from at least one of devices, apparatuses, and facilities installed in the plant;
• calculates a state value representing a change in the state of the plant using the plant information;
• and
• generates a plant state diagram in which at least one of a color and a density of the at least one of devices, apparatuses, and facilities from which the plant information is acquired is changed according to magnitude of the state value;
• and
• a display device that is connected to the server apparatus through a network and that displays the plant state diagram generated by the server apparatus as the information representing the state of the plant, wherein
• the server apparatus further generates the plant state diagram in which information representing an operation range of a worker operating in the plant is superimposed on a diagram representing the plant.

A plant state displaying method displaying information representing a state of a plant, the plant state displaying method comprising:

• acquiring plant information from at least one of devices, apparatuses, and facilities installed in the plant;
• calculating a state value representing a change in the state of the plant using the plant information;
• generating a plant state diagram in which at least one of a color and a density of the at least one of devices, apparatuses, and facilities from which the plant information is acquired is changed according to magnitude of the state value;
• and
• displaying the generated plant state diagram as the information representing the state of the plant, wherein
• in the generated plant state diagram, information representing an operation range of a worker operating in the plant is superimposed on a diagram representing the plant.

A plant state displaying apparatus displaying information representing a state of a plant, the plant state displaying apparatus comprising:

• a generator that:
• acquires plant information from at least one of devices, apparatuses, and facilities installed in the plant;
• calculates a state value representing a change in the state of the plant using the plant information;
• and
• generates a plant state diagram in which at least one of a color and a density of the at least one of devices, apparatuses, and facilities from which the plant information is acquired is changed according to magnitude of the state value;
• a display that displays the plant state diagram generated by the generator as the information representing the state of the plant;
• and
• a difference calculator that calculates the state value, wherein the state value is a difference between the plant information acquired through a network and a reference value.
