It is expressed as However, regarding the fluid flowing through the piping in FIG. 3, a line display combining the piping and the fluid is displayed, and the status display such as the presence or absence of the fluid in the piping and the flow direction is not particularly performed.

FIGS. 4 and 6 to 10 show monitoring screens according to the present embodiment. Instead of the conventional line display, the piping as equipment and the internal state are displayed separately. Since the pipes have different states at the left, right, up and down, such as a valve, a branch point, and a junction, the pipes are divided as shown in FIG. In the monitoring screen of the present embodiment, when the A1, B1, B2, and B3 valves are all closed, as shown in FIG.
The liquid B is displayed in a state of staying in the pipes 41 to 44, the pipe 49, and the pipe 50 in white circle display. When the B1 valve is open and the A1 valve is closed, the B liquid flows right through the pipes 41 and 42 (indicated by white triangles) into the B liquid filter, and flows into the AB storage tank through the pipes 43 to 46 from the filter. I do. In this case, it is displayed as shown in FIG. When the A1 valve is open, the liquid A flows right and downward (indicated by a black triangle) through the pipes 47 and 48, and also flows into the AB storage tank via the pipe 46. In this case, it is displayed as shown in FIG. Also, B

The three kinds of liquids of the mixed liquid (FIG. 9) flow, and these states are displayed so that they can be easily visually recognized. Also,
In this embodiment, a backwashing operation for cleaning the filter of the liquid B filter is performed. In this case, when the operator selects the backwash operation by operating a switch or the like, the operation command information editing unit 26 shown in FIG.
Then, the command signal of "B1 valve closed, B2 valve open, B3 valve open and B backwash pump ON" is automatically edited and output to the plant. During the backwash operation, the pipes 53, 52, 50,
The liquid B flows to the left in 43, 42, 49, 51. In this case, it is displayed as shown in FIG. That is, in the pipes 42 and 43, the B liquid flows rightward (forward direction) during the normal operation and leftward (reverse direction) during the backwash operation, so that the flow in the forward and reverse directions can be easily visually recognized. To be displayed. In this manner, the presence / absence of a medium in a pipe, a medium type, a medium mixing ratio, and a flow direction (stop, forward direction, reverse direction) are variably displayed on the monitoring screen of this embodiment for each pipe. It should be noted that this can be similarly displayed even if the variable display is distinguished by the display color and display shape. Here, the type of the liquid can be recognized on the screen only by the difference in the display color, but it is desirable to change the shape in consideration of the fact that the screen is copied in black and white. For example, the liquid A is displayed in a solid yellow color, and the liquid B is displayed in a light blue frame. When the liquid is in a stopped state, a figure having no direction such as a circle or a square is used. When the liquid is flowing, a figure such as a triangle or an arrow having a direction and a direction of the flow can be used is used. These pieces of display information are registered for each screen and each pipe in the piping status display graphic file of the screen information 24 in FIG. Table 1 is an example of a graphic file of the AB monitoring screen of the present embodiment, and shows a state in which a display shape for each liquid type and state is registered for each pipe in FIG.

[0009]

[Table 1]

In order to detect the state in the pipe, it is desirable to detect the presence or absence and the flow direction of the fluid by a sensor installed in the pipe. However, there are cases where it is difficult to respond to an increase in the number of signals or the installation of sensors, and it is practical to use a method of estimating the pipe state from the equipment and the operating state. In the piping state determination information 22 of FIG. 2, information for determining the piping state from the operating state and the equipment state is managed for each screen and each pipe, and the piping state determination unit 21 is sent from the equipment state determination unit 20. The state inside the pipe is estimated from the incoming device state information and the above-mentioned determination information. Table 2 is an example of a piping state determination file of the AB monitoring screen of the present embodiment, which is the piping state determination information 22, and shows how determination conditions are managed for each pipe in FIG. The liquid type indicates the type of liquid flowing through the corresponding pipe.
There are three types of liquid (liquid B), second liquid (liquid A), and third liquid (AB mixed liquid), and the other piping is only the first liquid. The first condition is a condition where the first liquid is present, the second and third conditions are conditions where the second and third liquids are present, respectively, and the fourth and fifth conditions are conditions where the fluid flows in the forward direction and the reverse direction, respectively. . For piping that does not have a corresponding condition, the corresponding condition is not applicable. Piping 45,
The fourth condition of 46 and 48 indicates that since there is no liquid stop state in these pipes, the flow of the fluid is unconditionally forward when the liquid is present, that is, when “there is liquid”. I have.

[0011]

[Table 2]

FIG. 5 shows a flow chart of the piping state determination process.
This process is performed on all the pipes. Step 10
At 0, the first condition is determined. If the condition is not satisfied, the process proceeds to step 102, and if the condition is satisfied, the fact that the inside of the pipe is the first liquid is stored as the pipe state information in step 101, and the process proceeds to step 107. In step 102,
If the second condition exists and the condition is satisfied, the existence of the second liquid is stored in step 103, and step 10
Move to 7. Similarly, in step 104, if the third condition exists and the condition is satisfied, the existence of the second liquid is stored in step 105, and the process proceeds to step 107.
If all of steps 100, 102, and 104 are not satisfied, the absence of liquid is stored in step 106, and the process ends. If any one of the above conditions is satisfied, the fourth condition is determined in step 107. If the condition is not satisfied, the process proceeds to step 109. If the condition is satisfied, the forward direction is stored in step 108, and the process ends. In step 109, if the fifth condition exists and if the condition is satisfied, step 11
If 0, the reverse direction is stored.
In, the stop of the liquid in the pipe is set as the pipe state information, and the processing is terminated.

The pipe state information determined by the above processing is passed to the screen display editing unit 23 shown in FIG. The screen display editing unit 23 reads out and edits the corresponding pipe state display graphic (Table 1) from the screen information 24, and outputs the display information to the CRT 4. As described above, FIGS. 6 to 10 show examples of the display. That is, FIG. 6 shows an example in which all the valves are closed, where a black circle indicates that the liquid A is stopped, and a white circle indicates that the liquid B is stopped. When there is no liquid in the piping, no display is made. FIG. 7 is an example of the normal operation, and a white triangle indicates that the liquid B flows to the right. FIG. 8 shows A
FIG. 9 shows a state in which the AB mixture is flowing by alternately displaying white and black triangles on the pipe 46. Further, FIG. 10 is a display example of the backwashing operation, in which white triangles, which are opposite to those in FIG.

As a display method, as shown in FIG. 11, a triangular pattern is moved and periodically displayed so that a dynamic display indicating a flow can be performed. For example, three types of patterns in which figures are shifted by one-third in the flow direction are prepared, and these are alternately displayed in a one-second cycle. Thereby, the visibility of the difference between the liquid stopped state and the flowing state is further improved.

In the conventional display method, as shown in FIG. 3, the flow direction is partially displayed by arrows at the start point, end point, intersection, and the like of the line. ADVANTAGE OF THE INVENTION According to this invention, the flow direction can be visually recognized in every part of a piping by displaying the directional figure which shows a medium on the whole piping. Also,
In the case where it is inevitable to display the piping status as a line due to restrictions on the amount of information displayed on the screen, etc.
It is also possible to display a line with a mixed color of each medium display color or a stripe pattern of each medium display color.

FIGS. 12 and 13 show another embodiment of the monitoring screen according to the present invention. FIG. 12 shows an example in which the flow rate in the pipe changes due to an opening control valve or the like.
It indicates that it is an opening degree, and simulates that the liquid A flowing through the pipe 48 has a flow rate of 60% by displaying a graphic in which a part of a black triangle is deleted. The display of the mixed state of the pipe 46 also simulates that the ratio of the liquid A is smaller than that of the liquid B. Further, FIG. 13 shows an example in which the thickness and the flow rate are simulated when the thickness of each pipe is different. In this example, if the thickness of the pipes 47 and 48 is “1”,
Represents a thickness of "3", and other pipes simulate a thickness of "2", and simulates a flow rate of the pipe by the number of medium display figures. In this example, the liquid A flowing through the pipe 46 and the liquid B
The mixture ratio of the liquid is 1: 2, and the mixture ratio is simulated by the number ratio of the black triangle and the white triangle. The piping state determination and display method in FIGS. 12 and 13 is complicated in the determination information and increases the number of display graphic patterns, but is basically the same as the above-described method. Further, it is also possible to display a monitoring screen in which the simulation methods of FIGS. 12 and 13 are combined.
