Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Industrial Application Field) The present invention relates to a monitoring device for monitoring the operating status of various plants such as nuclear power generation equipment or thermal power generation equipment.

(Prior art) Generally, in power generation equipment, such as boiling water type nuclear power generation equipment,
The drawing status of the various devices that make up the facility and the process amount of the facility are all displayed on the control panel in the central control room. The control panel is equipped with a CRT display that displays images of the operating status of the nuclear power generation equipment, and the operator can select any information and display it on the CRT display. .

The operator grasps the overall condition of the equipment from the information selected and displayed in the manner described above, in order to maintain safety or detect an abnormality at an early stage.

By the way, the above-mentioned CRT display displays the status of equipment and piping of the nuclear reactor equipment in a pattern on the display screen.

(Problem to be Solved by the Invention) In the conventional monitoring device described above, the pattern display displayed on the screen of the CRT display is a fixed display or a binary display of open and closed, and It was not possible to display the state quantity and form of the fluid flowing inside the pipe.

The present invention has been made based on the above-mentioned circumstances, and allows the state quantities of equipment and piping that constitute power generation equipment to be displayed in a pattern on the screen of a CRT display, allowing workers to It is an object of the present invention to provide a plant monitoring device that can visually confirm whether or not piping is in a normal state.

[Structure of the Invention] (Means for Solving the Problems) The plant monitoring device of the present invention includes a detector that detects the status, state quantity, etc. of various devices constituting the plant, and a display device that displays patterns of the various devices. and a signal processing circuit that receives the outputs of each of the detectors and generates a signal that causes continuous or stepwise changes in the pattern display depending on the outputs of the detectors.

(Function) In the plant monitoring device having the above configuration, the pattern display of the equipment on the display screen shows the status of each equipment by rotating, moving, or changing its size continuously or stepwise. A dynamic pattern display can be added to indicate the amount.

(Embodiment) Fig. 1 is a system diagram showing the overall configuration of an embodiment of the present invention.
FIG. 2 is a schematic diagram of an example of the pattern display, and FIG. 3 is a diagram showing the classification of the previous pattern display. First, FIG. 1 shows a system for monitoring some of the equipment that constitutes power generation. In this figure.

The central control panel has multiple (two shown) CRT displays 2.
A signal processing circuit 3 is provided in the CRT display such as this.
of! III force is input by signal m4. Further, a detector 6A for detecting the opening degree of the valve 5A, which is a device of the power generation equipment, is attached to the valve 5A, and the output of this detector is inputted to the signal processing circuit 3 through the signal line 4. Similarly, the pump 5B, which is a device of the power generation equipment, is provided with a detector 6B for detecting its discharge flow rate, pressure, and temperature, and its output is input to the signal processing circuit 3 via the signal line 4. Furthermore, a detector 6c is attached to the piping section 5C to detect the flow rate, flow direction, and fluid temperature in the piping, and its output is input to the signal processing circuit 3.

The signal processing circuit 3 processes the output signals from each of the detectors 6A to 6c and displays a pattern on the display screen of the CRT display 2.

FIG. 2 shows an example of pattern display on the display screen of the CRT display 2 of the central control panel 1. As shown in FIG.

In this figure, 11.11 is a valve pattern display, 12
is a pump pattern display, and 13.14 is a piping pattern display. The pattern display 11 of the valve is designed to indicate its open/closed state by color (the illustration shows the presence or absence of hatching), and the degree of opening is indicated by continuous or stepwise changes in the size of the pattern display. .

Further, on the pump pattern display 12, a spiral display 12a whose rotational speed changes depending on the magnitude of the discharge amount appears only when the pump is in operation.

Further, in the pipe pattern display 13, an arrow mark 13a is displayed which is oriented in the flow direction in the pipe and whose size changes depending on the magnitude of the flow rate. The pattern display of the flow direction and flow rate is, as shown in the pipe pattern display 14, a density display 14a that changes the brightness and darkness of the line density according to the flow rate and moves continuously in the flow direction. You may also do so.

Further, pressure, temperature, etc. are displayed numerically near the pattern display of the corresponding part, as shown at 15.16 in the figure.

FIG. 3 shows an example of pattern display. For example, when a valve is closed, a red pattern display 11a is displayed.
When the opening degree is more than 0% and less than 100%, a pattern display 1.1b of a size corresponding to the opening degree of only the outline is displayed, and when the valve is fully open, a green pattern display 11C is displayed. Also, regarding the pump, a pattern display 12 indicating the pump when the pump is stopped.
A spiral display 12a that changes the rotational speed in accordance with the rotational speed of the pump within the pattern only during operation.
The process of making it appear is as described above. Further, when there is no fluid in the piping pattern 13.14, only that pattern 13.14 is displayed, and when fluid is present in the piping, an arrow 13a indicating the flow direction and flow rate, and a light/dark density display 14a are displayed. As mentioned above, this is also done.

” Like the three-way system, the state quantities related to each device can be continuously or stepwise rotated, moved, or changed in size on the pattern display of the device on the display screen of the CRT display 2 of the central control panel. It is possible to add a dynamic pattern display that shows the state quantities to be used. Therefore, operators of power generation equipment
By visually observing the display screen of the display device 2, it is possible to intuitively grasp the status, state quantity, form, presence or absence of abnormality in the equipment, etc. of each device constituting the equipment.

Note that the present invention is not limited to the above embodiments. For example, instead of dynamic display using colors, dynamic display using shading may be adopted. Furthermore, the display is not limited to only a CRT display. Furthermore, it can be applied to any plant monitoring device other than the illustrated power generation equipment.

[Effects of the Invention] According to the plant monitoring device of the present invention, various devices constituting the plant are displayed in a pattern on the display screen J- of the display device,
Since the status, state quantity, form, and presence or absence of abnormalities can be dynamically displayed by changing patterns, operators can intuitively understand the current status of plant components just by looking at the display screen. , the accuracy of monitoring by operators is dramatically improved.
