Abstract

PURPOSE:To easily distinguish data and to prevent the confusion of a test, etc., by performing the picture display of plant data and simulation data distinction. CONSTITUTION:When the simulation data is used, a display index and the simulation data are set on a storage table 8 at ever input point by an input processing part 6. At the time of performing the picture display, a display processing part 11 displays the display data of a data preservation table 10 consisting of the plant data or the simulation data, and also, adds a picture processing so as to distinguish the simulation data from the plant data according to the storage table 8. In such a way, it is possible to distinguish the plant data from the simulation data on the picture display.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant data display device that displays plant sensor signals on a screen for monitoring plants such as nuclear power plants.

(Prior Art) For monitoring large-scale plants such as nuclear power plants, plant data display devices having a screen display function are used to perform more efficient monitoring over a wider area.

Generally, such a plant data display device can display simulation data in addition to displaying plant data. In other words, the input processing section performs processing such as alarm processing on multiple plant sensor signals (plant data) taken in by the process input device and sets them in a data storage table, and the display processing section retrieves the data from this data storage table and displays it on the CRT. Display the screen on the device. On the other hand, the simulation data is set in the simulation data table using an input device such as a keyboard, and the input processing section sets the set simulation data in the data storage table instead of the plant data. Therefore, when testing and adjusting the plant monitoring device, this simulation data is input and compared with the values processed by the plant monitoring device.

(Problem to be solved by the invention) However, in the combination test of the plant monitoring device and control equipment, some of the plant equipment is not moving, so this is supplemented with simulation data, but when this is displayed on the screen, the data is Tests were sometimes confused because it was not possible to distinguish whether the values were plant data or simulation data.Therefore, the purpose of the present invention is to distinguish between plant data and simulation data on a single screen display. The purpose of the present invention is to provide a plant data display device that is capable of displaying plant data.

[Structure of the invention]

(Means for Solving the Problems) The plant data display device of the present invention includes an input device (keyboard) processing section, an input processing section, and a display processing section. The input device processing unit sets simulation data and display/cancellation indicators in a storage table in correspondence with input points of a plurality of plant data. The input processing unit inputs a plurality of plant data, and at the input point where the storage table has a display index of simulation data, sets the set simulation data as display data in the data storage table. The display processing unit displays the display data of this data storage table on a screen and adds screen processing to distinguish between plant data and simulation data according to the index of the storage table.

(Function) When using simulation data, the input device processing section sets the display index and simulation data for each input point in the storage table. When displaying on the screen, the display processing section 5 displays display data of a data storage table consisting of plant data or shimmy region data, and adds screen processing to distinguish simulation data from plant data according to the storage table.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of a plant data display device of the present invention.

A process input device 2 inputs a plurality of plant sensor signals 1 from a plant and delivers them to a plant data display device 40 input processing section 6.

On the other hand, the keyboard processing unit 7 sets simulation data set from the input device (for example, a keyboard) 3 in the simulation data table 8. Here, in the simulation data table 8, IID numbers for identifying plant input points, indicators for canceling simulation data display, and simulation data are set in numerical order from engineering (see Figure 2). The plant sensor signals from the device 2 are input in order from the factory to the factory, and the display index of the simulation data (for example, 1
) is set, the simulation data is set; on the other hand, if the cancellation index (for example, O) of the simulation data is set, the plant sensor signal is subjected to alarm processing and set in the data storage table IO. Here, in the data storage table 10, IID numbers, indicators indicating the presence or absence of data defects, and data to be displayed are set in the order of IID numbers (see FIG. 3). The display processing section 11 displays the data in the data storage table 10 on the CRT display device 5, and also uses the simulation input point table 12 to distinguish and display whether the data is plant data or simulation data. Here, the simulation input point table 12 is IrD
The number and the indicator indicating cancellation of simulation data display are set in the order of the IiD number (see Fig. 4), that is, the display data corresponding to the IID number for which the display indicator of simulation data is set as shown in Fig. 5. Add S to the end of the value and output it to the CRT display device. The flow of this operation is shown in FIG.

The indicators for canceling the display of simulation data in the simulation data table 8 and the simulation input point table 12 described above can be changed using the keyboard 3;
Can be configured.

With the above, the displayed value using the simulation data is C
Since they can be easily distinguished on the RT screen, confusion during the test can be prevented.

In this example, an example was explained in which "S" is added to the end of the displayed value to distinguish between simulation data, but the same can be achieved by color-coding, brightness inversion, presence/absence of framing, etc. using the CR7 screen processing distinguishing means. Therefore, it can be applied not only to display but also to data value display such as par charts and trend graphs.

〔Effect of the invention〕

Therefore, since the present invention displays plant data and simulation data separately on the screen, data can be easily distinguished and confusion during testing can be prevented.
