Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Application Field) The present invention relates to a plant monitoring device for monitoring the process status of a plant. This invention relates to a data display method in a plant monitoring device that displays three-dimensional data.

(Prior Art) In a plant monitoring device that monitors the process status of a large-scale plant in a factory, a large amount of process data is input from the plant. The input process data is then processed into a state that can be easily understood by a supervisor, and displayed on a display screen of, for example, a CRT display device. The plant monitoring device also incorporates an operation panel for inputting various setting data to be sent to the plant. Then, the operator observes the various process data displayed on the display screen of the CRT display device, and if any abnormal data is displayed or when changing the operating conditions of the plant, the operator performs various operations on the operation panel. Send necessary setting data to the plant by operating buttons and keyboard.

Generally, in large-scale plants, the amount of data that is input from the plant and sent to the plant is enormous, so it is not possible to display all the data in an easy-to-understand manner with just one CRT display device, so a large number of CRT display devices are arranged. to display each data.

The operator needs to check each data displayed on each CRT display device from a distance. Therefore, each data is not displayed numerically; if the data is analog data or digital numerical data, the data is displayed as a bar graph, a pie chart, or the data value is displayed in color. . Furthermore, if the data to be displayed is, for example, onco[offco] binarized data, it is patterned and displayed. By displaying each data on the CRT display device in graphics or color in this manner, the operator can accurately grasp each data displayed on each CRT display device from a distance in a short time.

FIG. 4 is a diagram showing the on/off state of the binarized data displayed in colors or patterns on the display screen of the CRT display device.

FIG. 4(a) is a diagram showing the on/off states of each data D, to D6 in color. Red indicates OFF status, green indicates OFF status, and green indicates OFF status.
Off] state. In addition, FIG. 4(b) shows each data D1
The on/off status of ~D is displayed by changing the pattern. That is, when the right pattern of the pair of display areas is displayed, it indicates an [ON] state, and when the left pattern is displayed, it indicates an [OFF] state.

However, the data display method shown in FIGS. 4(a) and 4(b) also has the following problems that should be improved.

That is, which color of red or green is [on] and which color is [off], or which side of the pattern is displayed [on] and which side of the pattern is displayed [on and off]. Whether or not it exists is just a convention, and unless the operator knows about the convention, it is impossible to judge whether it is on or off. Therefore, this plant monitoring device becomes very difficult to handle for an inexperienced operator who does not understand the operating state of the plant monitoring device. Furthermore, if the displayed pattern or color information is misunderstood, the user may incorrectly perform an operation in the opposite direction on the plant.

(Problems to be Solved by the Invention) As described above, in the conventional data display method, there is a problem in that an operator who is not familiar with a plant monitoring device cannot accurately grasp the state of the data from the displayed patterns and colors.

The present invention was made in view of these circumstances, and
Even if the operator is unfamiliar with plant monitoring equipment,
It is an object of the present invention to provide a data display method for a plant monitoring device that can immediately grasp the on/off state of the data from the displayed pattern and improve the operability and reliability of the entire device.

[Configuration of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention displays process data input from a plant on a display device, and displays setting information input via an input device. In a data display method for plant monitoring equipment that displays data on a display device and sends it to the plant as setting data, each digital input/output data for the plant is displayed on the display screen of the display device as a three-dimensional image simulating the operating state of a push button. This is how it is displayed.

(Function) With the data display method of the plant monitoring device configured in this way, the on/off status of each data is displayed on the display screen of the display device as a three-dimensional image that assumes the operation status of the push button. Ru.

Therefore, even if an operator is inexperienced with this plant monitoring device, he or she will not mistakenly grasp the on/off state of the data.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing a schematic configuration of a plant monitoring device that employs the data display method of the embodiment.
