[0008]

Embodiments of the present invention described above will now be described in detail with reference to the drawings. [Embodiment 1] In this embodiment, an appropriate combination of connection end data of pipe connection portions is registered in a computer, and each connection end data represented by a bar code is converted into a bar when the connection of the piping system is completed. The code is read by a code reader, and the read data is input to the computer to check the adequacy of connection.

In this embodiment, as shown in FIG. 1, a case where four upstream pipes (11) to (14) and three downstream pipes (21) to (23) are selectively connected will be described. In this piping system,
When all the downstream side pipes are connected to any of the upstream side pipes, there are 24 combinations, but only some practical combinations of these 24 sets of piping modes are stored in the computer. . The names N _{1 to} Nm are given to the combinations of the pipes, and when a specific name among them is input, the set of the first connection end data and the second connection end data in the combination is called. Be done. or,
At the connecting end of each of the upstream side pipes (11) to (14), a connecting fitting (A)
, And each of the connecting ends of the downstream pipes (21) to (23) is equipped with a connecting fitting (B). And upstream piping (1
For the connection fitting (A) in ₁ ), attach the label (L
₁ ) is pasted. Similarly, upstream piping (12) to (1
Labels (L ₁ ) with bar codes (A ₂ ) to (A ₄ ) are attached to the respective connecting fittings (A) of ₄ ) so as to correspond to each other.

A similar label (L ₂ ) is also attached to the other connection fitting (B).
Is attached, and the downstream side piping (21) connection fitting (B)
Is a bar code (B ₁ ) on the downstream side piping (22)
Has a bar code (B ₂ ) on the downstream side piping (23)
There is a bar code (B ₃ ) for each. Therefore, when the connecting fittings (A) and (B) are connected to each other, the pair of labels (L ₁ ) and (L ₂ ) are arranged close to each other, as shown in FIG.

Among the practical pipe combinations, for example, the combination of the names N _n , as shown by the broken line in FIG. 1, connects the upstream pipe (11) and the downstream pipe (21) to the upstream pipe ( 12) and the downstream pipe (22), the upstream pipe (14) and the downstream pipe (23)
And are respectively connected, and this case will be described below. Note that this computer stores a program based on the flowchart shown in FIG. 4 and also stores a table shown in FIG.

The name (N) column of this table stores the name data of N _{1 to} Nm, and the display data (P) column stores the display of the combination of the pipes in association with the N _{1 to} Nm columns. , The first data (Q) row stores the bar code value (b ₁ ) on the connection fitting (B) side of the downstream pipe (21), and the second data (R) row connects to this. Bar code value on the metal fitting (A) side (a ₁ ) to (a
_m ) are stored in correspondence with the respective rows of the display data (P) column, and the connection fittings of the downstream side pipe (22) are stored in the third data (S) column.
The barcode value (b ₂ ) on the (B) side is stored and the 4th data (T)
The bar code value on the side of the fitting (A) that is connected to this is shown in the row.
(a ₁ ) to (a _m ) are stored in correspondence with each row of the display data (P) column, and the fifth data (U) column stores the connection fitting (B) side of the downstream side pipe (23). stored bar code value (b ₃₎ is sixth data (V) fitting (a) side bar code value of which is connected to the column _{(a 1) ~ (a m} ) is respectively said display data ( P) Stored in correspondence with each row of column.

Further, the label of the connection fitting (A) which is in the connected state by the bar code reader connected to the computer.
The bar code attached to (L ₁ ) and the label (L ₂ ) of the connecting fitting (B) is read, and the read data is input to the computer. The actual checking of the above piping will be described below. _If you input the name N _n using the keyboard, it means that the keyboard input value (W) is the name N _n.
It is judged by the step (31) in the search routine (30), and the display data of the Pn row of the display data (P) column in the table is fetched and displayed on the screen by the step (32).
That is, the downstream pipe (21) and the upstream pipe (11), the downstream pipe (22) and the upstream pipe (12), the downstream pipe (23) and the upstream pipe (14), respectively. A screen to connect appears on the screen. This display mode is displayed by, for example, a diagram or a table. After this, flag F = 0
At the same time, the connection fitting (A) and the connection fitting (B) are automatically or manually connected based on the above display.

After this, the bar code reader reads the bar code of the label (L ₂ ) on the side of the connecting fitting (B) of one connecting portion, and then the label on the side of the connecting fitting (A) to be connected to this. Scan the (L ₁ ) barcode. In this example,
It is premised that one bar code reader reads a set of bar codes in the connection section in the order described above, but there is no restriction on which connection section the bar code is read from. Since the connection mode of the pipe is a combination of the names Nn, each bar code value in the Nn row of the table is called and the following check is executed.

Therefore, the connecting portion of the downstream pipe (21) is first
If read, step (33) and step (34)
Depending on the combination of the
Be checked. In other words, according to step (33),
(Q) column Qn row data (B ₁) And a barcode reader
Whether the bar code value read by
Is determined, and if they match, the barcode
Connection fitting (A) of the connection part read by the reader
Side bar code value and the data in the Rn row of the (R) column of the table
Are determined by step (34).
It

Then, when the connection portion of the downstream side pipe (22) is read first, the step (3
The combination of 5) and step (36) checks the bar code set for this connection, and if the connection on the downstream pipe (23) is read first, steps (37) and (38). ) And the pair of bar codes at this connection is checked. And the bar code value (b ₁ ) ~
If a barcode other than (b ₃ ) is read, an error message will be displayed.

When the check work is executed by the pair of steps, the flag F = F + 1 is set. After this, it is judged in step (39) whether F = 3, and F <
In the case of 3, the reading of the next bar code is waited for. Then, when any of the bar code values (b ₁ ) to (b ₃ ) is read, the series of check operations described above is executed. When the above-mentioned check is completed for the three connection portions, F = 3, so this is judged in step (39) and the check operation is ended.

In this way, it is possible to check the suitability of the connecting portion of the piping system by reading the barcodes of the connecting portion in a predetermined order by the barcode reader. [Embodiment 2] In the above embodiment, one bar code is read by the bar code reader. However, for example, it is adjusted according to the distance between the label (L ₁ ) and the label (L ₂ ) arranged in the pipe connecting portion. Alternatively, a bar code reader having two reading units may be used, or a method in which the bar code of the label (L ₁ ) and that of the label (L ₂ ) are simultaneously read by two bar code readers may be adopted. In this case, the first embodiment described above is used.
The barcode reading step and steps (33) to (38) in the flowchart in FIG. 5 are as shown in FIG. 5, and the flowchart is simplified and the reading order is not restricted.

[Others] Each part of the above embodiment can be modified as follows. ． Although the bar code reader is connected to the computer by wire in the above-described embodiment, the bar code reader may be connected to the computer by a wireless signal. ． It is also possible to use a computer as a microcomputer and connect it to a bar code reader to make the whole as a handy type pipe connection checking device. ． The first connection end data and the second connection end described in the above section.
