Abstract

PURPOSE:To recognize quickly the state of the process quantity by providing plural display points in response to the positions of equipments with the distance secured from a standard position by an amount equivalent to the process quantity of each equipment and also the display lines connecting those display points. CONSTITUTION:A radar 10 shows the gas temperatures of 12 combustion chambers in the form of a distribution chart and the angles formed when a circle is divided into 12 pieces correspond to the positions of those combustion chambers. The gas temperature of each chamber s measured and the display points 12 are displayed on the straight lines obtained by dividing a circle into 12 parts in the size corresponding to each temperature level. These measured temperatures are displayed by the display lines 13 connected with each other in the form of the broke lines of points 12. Then the mean level is obtained among those gas temperatures of 12 combustion chambers and at the same time the mean value display points 22 are displayed on the 12 divided straight lines in the length corresponding to said mean temperature level. Then 12 points are displayed by a broken display line 22. Thus it is possible to visually recognize the deviation between each gas temperature and the overall mean level by displaying a pattern 20 on the chart 10 at the same coordinates. In addition, each temperature distribution can be recognized quickly.

2a is a process quantity, which numerically indicates the gas temperature in each combustion chamber, and is displayed in each display section Ia. In FIG. 2, the gas temperature (process amount) in each combustion chamber 1 is numerically displayed at a fixed position, and the operator who monitors this state checks the temperature in the process by looking at this screen.

[Problem that the invention seeks to solve]

Conventional display systems were configured as described above, so operators read each numerical value as a process quantity, recognized it in their heads, and then determined whether the temperature of each part is normal or approximately the same value. It is necessary to recognize what is being shown, which causes problems such as misidentification and time-consuming problems. Does this invention have the above problems? The overall purpose is to obtain a device that can visually recognize the process amount, reliably visually recognize it, and also instantly recognize deviations from the overall average.

[Means for solving problems]

Therefore, the first invention related to this screen display method is such that the screen is provided corresponding to the position of each device such as a combustion chamber, and the distance from the reference position is set to a distance corresponding to the process state of each device. It is characterized by providing a plurality of display points and a display line connecting the display points.

In addition to the first invention, a second invention related to this screen display method is a screen that is provided corresponding to each device on the same screen, and whose distance from the reference position is the average of the process amount of all the devices. It is characterized by displaying a display pattern consisting of average value display points set at distances corresponding to the values and average value display lines connecting each average value display point.

The average value 2 of the state quantity of the process of the equipment is shown.

〔Example〕

One embodiment of the present invention will be described below based on the drawings. FIG. 1 is a diagram of a screen display system showing a seventh embodiment of the present invention. In the figure, 10 is a radar chart showing the gas temperature of each of the 12 combustion chambers as a distribution diagram, and 11 is a reference representing the center of the circle. The center point 12 as a position is located so as to surround the center point 12, and is located so as to maintain the angle obtained by dividing the circle into 12, and therefore is a display point corresponding to the position of each combustion chamber. The distance from point 11 is set to a distance corresponding to the state of gas temperature (process amount) in each combustion chamber. 13 is a display line connecting each display point 12.
0 represents the average value 7 of the process quantity of each combustion chamber'f display pattern, 21 represents the average distance from the center point 11 as the reference position set to the distance corresponding to the average value of the gas temperature of each combustion chamber The value display point 22 is an average value display line connecting the average value display points 21 and displaying the average value.

Further, 3 is a digital display value of the gas temperature in each combustor chamber, and 4 is an average value digital display value of the average amount. These are displayed on the same screen P. Here, when the circle is divided into ¥12, the angle corresponds to the position of each combustion chamber.

In such a display method, all gas temperatures are measured and the values are plotted on a straight line divided by Y12 circles (Nx30'(N-O~1
