The present invention relates to a preferred method for displaying the operating status of a plant.

[Conventional technology]

2. Description of the Related Art When monitoring the operating status of various plants such as a power plant from a remote location, the operating status of the plant is monitored by displaying symbols of each device in the plant on a screen. In this case, as shown in Figure 5, the display area of the CRT screen is divided into two areas, one area displays the symbols and system diagram of each device, and the other area calls the operator's attention. A configuration is adopted that displays the tag message as an image.

As shown in FIG. 6, the contents of the tag message are such that file message information in the memory corresponding to each CRT screen is stored.

In other words, when the date and time of periodic inspection and its contents are determined, if you input the corresponding equipment name and message information from the keyboard, the message information will be stored in the specified file in the memory and also in the tag message area of the CRT. The content of the message information is displayed as an image. for example.

When the circuit breaker CB8124 is stopped on August 9th, an image to that effect is displayed in the tag message area of the CRT screen. Thereby, the operator can confirm that the circuit breaker CB8142 will be stopped on August 9th by checking the contents of the tag message area.

[Problem that the invention seeks to solve]

However, with conventional display methods, there is not a one-to-one correspondence between each piece of plant equipment and the message information.
From the image displayed on the RT screen, it was not possible to immediately determine whether or not caution was required when operating each device.

That is, the operator remotely controls the operation of the plant while monitoring the symbols of each device, but at this time must also check the contents of the tag message area. However, since a lot of message information is displayed as images in the tag message area, it is not possible to immediately judge whether or not to operate the equipment according to the message information. Ta. This becomes more difficult as plant equipment increases. Also, as the number of devices increases, it becomes necessary to display the symbol of the device as an image, but for this reason, there is not enough tag message display area, and the message information is displayed with I[Il! I had to use words such as For this reason, it is not possible to write a sufficient message, which may impede the operator's quick judgment, and may also impede improvements in the reliability and functionality of the entire plant control.

It is an object of the present invention to provide a method for displaying the operating status of a plant, which is capable of ascertaining whether or not each piece of equipment in the plant requires attention during plant operation, as well as immediately identifying precautions for equipment that require attention. Our goal is to provide the following.

Means for Solving Problem c] In order to achieve the above object, the present invention (1) displays images of the symbols of each equipment of the plant on the screen together with the system diagram, as shown in FIG. 1 (step 100). , display a tag mark as an image near a specific symbol among the symbols on the screen to alert the operator (Step 102)
, store message information regarding the content of each tag mark in memory in association with the symbol to which the tag mark is attached (Step 104); and in response to an operation for specifying a tag mark on the screen, specify message information from the memory. This method employs a method of displaying the operating status of the plant, in which the content of the extracted message information is displayed as an image on the screen (step 108). ′ [Operation] The symbol and system diagram of each device are displayed as images on the screen, and 1. Since the tag mark is displayed as an image near a specific symbol, it is possible to understand whether each device requires attention when controlling each device based on the presence or absence of the tag mark. Additionally, when a tag mark is attached to the symbol of the device to be controlled, if you perform an operation to specify this tag mark, the contents of the specified message information will be displayed as an image on the screen, allowing you to immediately understand the precautions. can do.
