Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] In a pipeline system diagram controlled by a computer and displayed on a display unit, by opening and closing a valve on an inflow side and a valve on an outflow side of a pipeline, a state in which a fluid flows in the pipeline is set. The color change method of the pipeline system diagram changes the color when it changes, and changes the color to return to the original when it changes from the flowing state to the non-flowing state.The table used to change the line color is easy. For the purpose of providing a color change method that can be created on the basis of the above, and for which a color change method can be determined quickly, a computer is provided with an inlet side valve and an outlet side valve for each inlet side valve. Shows the entire unit line where the flow changes due to the opening of both the inflow-side valve and the outflow-side valve, and for each outflow-side valve, every inflow-side valve Both inflow and outflow valves between the valve and the inflow valve Has a facility table that shows all the unit lines whose flow changes due to opening, and has a line information table that has a counter for every unit line, and also opens and closes the inflow side valve or the outflow side valve. When the valve on the inflow side and the valve on the outflow side of the equipment table of the corresponding valve are both opened, 1 is added to all the unit lie counters in the line information table between them, and the valve is closed. When the counter changes from 0 to 1, the color of the unit line of the counter is changed when the counter changes from 0 to 1, and when it changes from 1 to 0, the unit line of the counter changes. The color changing means for restoring the original color is used.

[Industrial application field]

The present invention controls the color of a pipeline system diagram that is controlled by a computer and displayed on a display unit by opening and closing a valve on the inflow side and a valve on the outflow side of the pipeline to change the color when the fluid flows into the pipeline. The present invention relates to an improvement of a color changing method of a pipeline system diagram in which a color is changed so that the color is returned to the original color when the color changes from a flowing state to a non-flowing state.

An example of a display device having a display unit controlled by a computer is as shown in FIG.
It has a computer 10 composed of M2 and RAM3 and a display unit 4, has a required program and table in ROM2, and changes the color of the unit line of the pipeline system diagram displayed on the display unit 4 under the control of the processor 1.

In addition, the pipeline system diagram of one example is as shown in FIG. 7, where A and B are valves on the inflow side, C and D are valves on the outflow side, and a, b, c, d, e indicates a unit line (hereinafter referred to as a line) in which the flow changes due to opening and closing of the valve.

In this case, if the valves A and C are open, the lines a, c, d in which the fluid flows are changed in color, and if the valves A and D are open, the lines a, c, e in which the fluid flows are changed. Change the color of valves B and C
When is open, the lines b, c, d in which the fluid flows are changed in color, and when the valves B and D are open, the lines b, c, e in which the fluid is changed are changed in color.

Of course, even if only the valves A and B on the inflow side are open, and even if only the valves C and D on the outflow side are open, the fluid does not flow, so the color of the line is not changed.

Also, for example, when valves A, B, and C are open and lines a, b, c, and d are changed in color, when valve A is closed, fluid does not flow through line a. return.

It is desired that the color change of the line as described above is quick in real time.

The following description will be made by taking the pipeline system diagram of FIG. 7 as an example.

[Conventional technology]

 A conventional example will be described below with reference to the drawings.

FIG. 8 is a diagram showing the line color changing conditions of FIG. 7, FIG. 9 is a line table showing the lines for which color change judgment should be performed by the change of the valve of the conventional example, and FIG. 10 is the color change of the line of the conventional example. The condition table, FIG. 11 is a flowchart of a conventional color changing program.

To change the line color of the conventional pipeline system diagram,
FIG. 6 shows a line table showing the line for which color change judgment is to be performed by the valve change for each valve shown in FIG. 9 and the line color change condition table for each line shown in FIG. It is stored in the ROM 2 shown and is controlled by the processor 1.

The line table shown in FIG. 9 is a table showing lines that may change to a state in which fluid flows when the valve is opened and closed. When the valve is opened and closed, it is possible to determine whether the color of the line of this table is changed. It is provided so that it can be performed.

That is, lines a, c, d, e are shown for valve A, lines b, c, d, e are shown for valve B, and lines a, c, d, e are shown for valve C.
b, c, d are shown, and for valve D, lines a, b, c, e are shown.

The line color change condition table for each line in FIG.
When the line for which color change is determined is determined by the line table of FIG. 9, it is a table for determining whether or not the color should be changed for that line.
First, the color change condition of the line shown in FIG. 8 is obtained, and based on this, the number of valves and valve names related to the color change determination of this line are written in the lower stage, and the upper line shows the number of valves. For all cases, the number of conditions for changing the color if the valves related to color change determination are all open and the conditions for changing the color if the valve indicated by 1 related to color change determination is all open. The valve order is 1,0.

For example, the color change condition table of the line a shown in FIG. 10 will be described. From the top of FIG. 7, the valves related to the color change determination are A, C, D and the number of valves is 3. ,
If the valves related to the color change determination are all open, there are two conditions for changing the color: when valve A and valve C are open (condition 1) and when valve A and valve D are open (condition 2). Therefore, the number of judgment valves is 3 in the lower stage, the names of the valves are A, C, D, and the number of conditions in the upper stage is 2. In the case of condition 1, 1, 1, 0, and in the case of condition 2, It is set to 1,0,1.

Explaining the lie color change condition table of the line c, from the third stage of FIG. 7, the valves related to the color change determination are A, B, C, D and the number of valves is 4, and the color change determination is The conditions for changing the color when all the valves related to are open are: when the valves A and C are open (condition 1), when the valves A and D are open (condition 2), and when the valves B and C are open. There are four cases, one is open (condition 3) and the other is when valve B and valve D are open (condition 4). Therefore, the number of judgment valves is 4 and the names of the valves are A, B, and C and D, the number of conditions in the upper row is 4, condition 1 is 1,0,1,0, condition 2 is 1,0,0,1 and condition 3 is 0,1, 1,0, and in the case of condition 4, 0,1,0,1.

Next, for example, the case where the valves A, B, C, D are closed, the valve A is opened, and then the valve C is opened will be described.

When the valve A is opened, the lines for which color change should be determined in FIG. 9 are a, c, d, and e, but the case of the line a will be described as a typical example.

The color change of the line a is determined according to the program of FIG. 11 with reference to the color change condition table of the line a of FIG. 10. Therefore, the program of FIG. 11 will be described in order.

In FIG. 11, i represents the numbers of conditions 1, 2, 3, ... And m represents the number of conditions.

In step 1, i is set to 1, and the process proceeds to step 2. Condition 1
In the judgment valves A and C of A, A is open and C is closed.
, The i is set to 2, and the process proceeds to step 5, where i is the condition number 2
Since it is not larger, return to step 2, and in the judgment valves A and D of condition 2, A is open and D is closed, so step 4
I is set to 3, and i is set to 3, and i is larger than 2, so that the process proceeds to step 6 and stops without changing the color of the line.

Next, when the valve C is opened, the lines for which color change should be judged are a, b, c, d in FIG. 9, but the case of the line a will be described as a representative example.

To determine the color change of line a, line a in FIG.
The color changing condition table is referred to and the program is performed in accordance with the program shown in FIG. 11. Therefore, description will be given in order of the program shown in FIG.

In step 1, i is set to 1, and the process proceeds to step 2. Condition 1
In judgment valves A and C of A, A is open and C is also open, so step 3
Go to and change the color of the line and stop.

The color is changed as described above.

[Problems to be solved by the invention]

However, in the conventional color changing method, in order to create the line color changing condition table, the line color changing condition as shown in FIG. 8 must be obtained and then created.

In this case, in order to obtain the color change condition of the line as shown in FIG. 8, it is necessary to obtain the condition of each valve in order to change the color for each line. If there are many valves, there is a problem that it takes a lot of time.

When the valve is opened or closed, the lines related to this are first obtained from the line table shown in FIG. 9, and then the line color change condition table for all lines shown in FIG. 10 is referred to. Then, it is necessary to judge the color change by the program of FIG. 11, and there is a problem that it takes time to judge the color change.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a color changing system for a pipeline system diagram in which a table used for changing the color of a line can be easily created and a color change can be determined quickly.

[Means for solving problems]

 FIG. 1 is a block diagram of the principle of the present invention.

In the pipeline system diagram which is controlled by the computer 10 and displayed on the display unit 4, the color changes when the fluid enters the pipeline by opening and closing the valves on the inflow side and the outflow side of the pipeline. , In the color change method of the pipeline system diagram, in which the color is changed so as to restore the color when the flow state changes to the non-flow state, the computer 10 For each valve, the entire unit line in which the flow changes between the valve on the inflow side and the valve on the outflow side due to the opening of both the inflow side valve and the outflow side valve is shown. For valves, for each inflow side valve, a unit line between the outflow side valve and the inflow side valve, where the flow changes because both the inflow side valve and the outflow side valve are open. Is equipped with an equipment table (A) showing all of the above, and also has a counter for every unit line Comprising a line information table (B).

Further, when the valve is opened and closed and the valve on the inflow side and the valve on the outflow side of the equipment table of the valve are both opened, the counters of all unit lines in the line information table (B) are set to 1
Is added, and when it is closed, 1 is subtracted from all the counters of the unit lie between them, and when the counter is changed from 0 to 1, the color of the unit line of the counter is changed to 1 to 0. In this case, a color changing means (C) for returning the color of the unit line of the counter to the original color is provided.

[Action]

According to the present invention, as the table, for the valves on the inflow side or the outflow side, a valve that is simply a color change determination condition as equipment is determined from the pipeline system diagram, and all of the valves between these valves are determined. It is only necessary to obtain the line for each valve and use this as a table for the equipment table (A) for each valve and the lie information table (B) for each line that has a counter for each line. As described above, it is simple and hassle-free, and the color change determination of the line is as follows. When the valve is opened and closed, the equipment table of the valve and the line information table (B) are used. Depending on the state of the side valve,
The value of the counter of the line in the meantime is changed, and when the counter is changed from 0 to 1, the color is changed, and when the counter is changed from 1 to 0, the color changing means (C) for returning the color can be used. You can quickly judge the color change.

〔Example〕

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 2 is a diagram showing a facility table of each valve of the embodiment of the present invention, FIG. 3 is a diagram showing a line information table of the embodiment of the present invention, and FIG. 4 is a color changing program of the embodiment of the present invention. FIG. 5 is a flow chart showing the change of the counter value and the change of color by opening and closing the valve according to the embodiment of the present invention.

In order to create the equipment table shown in FIG. 2, the case of the valve A on the inflow side will be described. There are two valves C and D on the outflow side that are the color change determination conditions. The lines between are a, c, d
, And the lines with the valve D are a, c, and e.

Therefore, in the equipment table of valve A, the number of judgment valves is 2
Then, the judgment valve C, then the number of lines between 3 and 3 lines a, c, d, then the judgment valve D, then the number of lie between these 3
And three lines a, c and e are shown.

In this way, as shown in FIG. 2, an equipment table is created for the valves A, B, C, D.

As the line information table, the line is 5 of a, b, c, d, e.
Since they are individual, a line information table as shown in FIG. 3 having counters corresponding to these lines is created.

Therefore, when the valve changes to open or closed, the color of the line is changed by the color changing program shown in FIG. 4 using the changed valve equipment table.

Due to this color change, in the initial state shown in FIGS. 5 (1) to (5), the valve A changes to open, the valve C changes to open, the valve B changes to open, and the valve A changes to closed. Will be explained.

In the initial state shown in (1), since the valves A to D are all closed, as shown in FIG. 5 (1), the counters of each line are all 0 and no color change is performed.

Further, when the valve A shown in (2) is opened, the equipment table of the valve A shown in FIG. 2 is referred to and the color is changed by the program shown in FIG.

First, since the valve is opened in step 1, the process proceeds to step 2, the judgment valve number i is set to 1, and the process proceeds to step 3 where the first judgment valve C is not open. Since i + 1 is 2, the process proceeds to step 5, and since 2 is not larger than 2 which is the number of judgment valves, the process returns to step 3 and 2
Since the second judgment valve D is also not open, the routine proceeds to step 4, i is set to i + 1 of 3, and the routine proceeds to step 5, where 3 is larger than the number of judgment valves 2, so stop at this.

That is, as shown in (2) of FIG. 5, all the counters are 0 and the color is not changed.

Next, when the valve C is opened as shown in (3), the valve C in FIG.
Referring to the equipment table of, the color is changed by the program of FIG.

First, since the valve is opened in step 1, the process proceeds to step 2, the i of the judgment valve number is set to 1, and the process proceeds to step 3 where the first judgment valve A is open. Add 1, to the counters of c, d.

Next, the process proceeds to step 7, and if there is a counter that has become 1, the line of the counter that has become 1 in step 8
Change the color of a, c, d. Next, in step 4, i is set to i
+1 is set to 2, and the process proceeds to step 5, where 2 is 2 which is the number of judgment valves.
Since it is not larger, the procedure returns to step 3, and the second judgment valve B is closed. Therefore, the processing advances to step 4, i is set to i + 1 = 3, and the processing advances to step 5, where 3 is larger than 2 which is the number of judgment valves. Stop with this.

That is, as shown in FIG. 5 (3), the counters of the lines a, c, d have become 1, so that the colors of the lines a, c, d are changed.

Next, as shown in (4), when the valve B is opened, the equipment table of the valve B in FIG. 2 is referred to, and the color is changed by the program in FIG.

First, since it was opened in step 1, the process proceeds to step 2, the i of the judgment valve number is set to 1, and the process proceeds to step 3 where the first judgment valve C is open, so the process proceeds to step 6 and the line b The counters of c, d are incremented by 1.

Next, the process proceeds to step 7, and if there is a counter having a value of 1, the color of the line b of the counter having a value of 1 is changed in step 8. Next, the process proceeds to step 4 and i is i + 1
No. 2 and the process proceeds to step 5, and since 2 is not larger than 2 which is the number of judgment valves, the process returns to step 3 and the second judgment valve D
Is closed, the process advances to step 4, i is set to i + 1 of 3, and the process advances to step 5 where 3 is larger than the number of judgment valves, 2 and the process is stopped.

That is, as shown in FIG. 5 (4), since the counter of line b has become 1, the color of line b is changed.

Next, as shown in (5), when the valve A is closed, the facility table of the valve A in FIG. 2 is referred to, and the color is changed by the program in FIG.

First, since it has not changed to open in step 1, it proceeds to step 9, and since it has changed to closed, it proceeds to step 10, sets i of the judgment valve number to 1, and proceeds to step 11 to open the first judgment valve C. So go to step 14, line between
Decrement 1 from the counter values of a, c, and d.

Next, the process proceeds to step 15, and if there is any counter that has become 0, at step 16 the color of the line a of the counter that has become 0 is restored. Next, in step 12, i is i + 1
No. 2 and the process proceeds to step 13, and since 2 is not larger than 2 which is the number of judgment valves, the process returns to step 11 and the second judgment valve D
Is closed, the process proceeds to step 12, i is set to i + 1 of 3, and the process proceeds to step 13 where 3 is larger than the number of judgment valves, 2 so the process is stopped.

That is, as shown in FIG. 5, since the counter of line a has become 0, the color of line a is restored.

〔The invention's effect〕

As described in detail above, according to the present invention, the table used for changing the color of the lie can be easily created only by looking at the equipment of the pipeline system diagram, so the table can be created easily and the color of the line can be changed. Since it can be performed by referring only to the equipment table of the opened / closed valve and using the counter of the line information table, there is an effect that the color change can be speeded up.
