Description

  The present invention relates to a piping production management method and a system thereof.

  When constructing pipes for water, gas, electricity, and communication at a construction site such as a plant, an unprocessed standard pipe is cut into a plurality of pipes of a predetermined length and assembled based on a pipe diagram. At that time, the cut pipes may be managed by marking them as product names, specifically, engraving. At this time, the cut pipes are connected by combining elbows or joints based on the piping diagram with reference to the above-mentioned markings.

In such a case, a technique has been proposed in which the above-described mark is automatically given to the pipe before cutting to reduce the material cost by reducing the remaining pipe (see, for example, Patent Document 1). Also, pipe information is extracted from the design drawing to create a straight pipe information list, and the straight pipe creation order list is created by rearranging the straight pipe data constituting the straight pipe information list according to the raw material pipe creation order. A recording medium (for example, see Patent Document 2) that is used for tracking is also proposed.
JP 7-148611 A (paragraphs 0012 to 0024, FIG. 1) Japanese Patent Laid-Open No. 11-347992 (paragraphs 0011 to 0013, FIG. 1)

By the way, when a manufacturer of plant equipment or the like orders pipes (including those that have been processed such as cutting) from a material manufacturer and assembles them at a factory or construction site, Execute and manage each production process from stamping, material verification, assembly, welding / heat treatment, and construction. In the middle of the process, preparation of material management records, preparation of inspection records, or witness inspection by a third-party organization are performed as necessary.
However, each of the techniques disclosed in the above-mentioned patent documents reduces the material cost by reducing the remaining pipes, or refers to the straight pipe creation order list recorded on the recording medium. It was intended to know, and did not reduce the burden on the creator involved in creating a management document in the series of processes from material ordering to construction as described above, or reducing the creation time.

  The present invention has been made in view of the above-described circumstances, and reduces the burden of creating a management document necessary for managing each production process, and reduces the time required for the creation and inspection of the piping production management. An object is to provide a method and system thereof.

  In order to solve the above-described problems, the present invention generates a plan drawing for cutting an unprocessed fixed pipe according to a dimension to be processed based on a pipe manufacturing drawing by a computer of a manufacturer. The processing order information including the material drawing number and the material identification number assigned to each pipe cut based on the board drawing is transmitted to the material manufacturer's computer via the network. The material manufacturer's computer records the assigned material identification number together with the material test data on the wireless tag chip attached to each pipe cut based on the plan drawing. The material identification number and material test data are read from the RFID tag chip attached to each cut pipe, and the material standard value registered in the database is searched using the material identification number as a key. Therefore, it was decided to generate a material management record table in which the verification results were recorded.

  According to the present invention, the material identification number recorded on the RFID tag chip can be associated with, for example, each specification of design data, processing data, and manufacturing process data, and without this, confirming the actual product. In addition, the management record table can be automatically generated, and the burden on the worker for creating the management document created in each process can be reduced, and the time required for creation and inspection can be reduced.

Here, an example of communicating with the communication unit 211 of the server 21 via the communication unit 132 is shown.

FIG. 3 and FIG. 4 are drawings cited for explaining each work process of the pipe production management method according to the present embodiment.
The work processes shown in FIG. 3 and FIG. 4 explain each work process such as processing, assembly, and inspection, which is an actual work performed by a worker in the material maker 10 and the manufacturing maker 20, and will be described in detail. Starting from the acceptance inspection (S31) of the material maker 10, ruled line (S32), material verification (S33), material witness (S34), cutting (S35), bending operation (S36), assembly (S37), nondestructive inspection ( S38), heat treatment (S39), undercoating (S40), shipping preparation (S41), and finished product delivery (S42) are delivered to the site. In FIG. 3 and FIG. 4, “■” indicates the RFID tag 1 attached to both ends of each pipe cut from the fixed pipe by the material manufacturer 10. Hereinafter, the exchange between the computer of the material manufacturer 10 and the computer of the manufacturer 20 will be described for each process (see FIGS. 1 and 2 as appropriate).

First, a series of flows from the acceptance inspection (S31) shown in FIG. 3 to cutting (S35) in the production process will be described. FIG. 5 is an example of a flowchart showing the flow of processing in the computer (server 21) of the manufacturer 20 at this time.
In FIG. 5, the server 21 of the manufacturer 20 first fetches CAD (Computer Aided Design) data and the like of the manufacturing parts table including the material standard value for each pipe and the pipe manufacturing diagram showing the combination of these pipes. (S51) and register in the DB 213. Here, FIG. 8 shows an example of the production parts table fetched by the server 21 and the CAD data of the piping production drawing. As shown in FIG. 8, in the production parts table, for each pipe, the part number of the pipe in the pipe production drawing, the material identification number uniquely determined for this pipe, and welding or screwing at both ends of this pipe Contains the joint number uniquely defined for the joint part connected in, the pipe model number that is the model number of the regular pipe from which the pipe is cut out, and the material standard value information such as the material and dimensions of this pipe I understand that.

Next, the server 21 of the manufacturer 20 calculates the same material, the same dimensions, the cutting allowance, the shrinkage allowance, etc. from the CAD data of the piping manufacturing drawing registered in the DB 213, and adjusts it to the constant length pipe length of the material manufacturer 10. A rational plan drawing (pipe cutting diagram) is generated and output (S52). An example of a pipe cut diagram generated at this time is shown in FIG. In the pipe cut-out diagram shown in FIG. 9, the numbers surrounded by circles correspond to the product numbers of the piping in the production parts table shown in FIG.
In addition, if the material is piping as in this embodiment, the generation of the plan drawing (pipe cutting diagram) can be realized with a simple algorithm considering only the length direction, and if it is a two-dimensional plane such as a steel plate, For example, it can be realized by applying a conventionally known plate cutting method as described in JP-A-11-039358.
Then, a unique pipe identification number is assigned to the fixed-size pipe automatically numbered at this time (S53), and these pieces of information are stored in the DB 213, and the production parts table and the pipe production diagram shown in FIG. The CAD data and the pipe cut information shown in FIG. 9 are combined and sent as processing order information to the server 11 of the material manufacturer 10 via the network 31 to place the processing order (S54).

  The pipe identification number assigned here is copied and written on the RFID tag chip 1 attached to both ends of the pipe cut out from the pipe in the material inquiry (S33) procedure described later. In this embodiment, online electronic ordering is performed by a computer. However, the server 21 of the manufacturer 20 outputs a slip on which information on processing order is printed by a printing unit such as a printer (not shown) and places an order. You can also

  The material manufacturer 10 that has received the order receives the pipe identification number assigned in S53 shown in FIG. 5 for each wireless tag chip 1 during the acceptance inspection (S31) of the fixed-size pipe from the steel manufacturer that manufactured the pipe. One of them and the material test data (mill sheet) of the pipe acquired from a steel manufacturer or the like are input and pasted on each fixed pipe. Then, through the ruled line (S32) and material collation (S33) steps, before cutting the fixed pipe, the RFID tag chip 1 that duplicates the information contained in the wireless tag chip 1 attached to the fixed pipe, Affixed to both ends of each pipe to be cut, the server 11 of the material manufacturer 10 includes CAD data of the production parts table and the pipe production drawing included in the processing order information transmitted in step S54 (see FIG. 8). Based on the above, the material identification number corresponding to the pipe to be cut and the joint number corresponding to each joint part are recorded in each pasted RFID tag chip 1.

Then, the material manufacturer 10 reads the material identification number and the material test data from the wireless tag chip 1 attached to each pipe and transmits them to the server 21 of the manufacturer 20.
Returning to FIG. 5, the server 21 of the manufacturer 20 determines whether or not the material identification number and the material test data have been received (S55), and receives these information (in the case of “Yes” in S55). The material standard value registered in the DB 213 and the received material test data, which are searched using this material identification number as a key, are collated with each other, and the collation result between the material standard value and the material test data shown in FIG. Is output (S56). In the comparison result between the material standard and the material test data shown in FIG. 10, the record of “standard value” is the material standard value registered in the DB 213 in advance, and the record of “result” is read from the wireless tag chip 1. It is the material test data of the piping. The collation result between the material standard and the material test data shown in FIG. 10 corresponds to the material management record table in the claims, and can be displayed on the display device of the server 21 of the manufacturer 20. .

Next, FIG. 6 shows the computer (server 11) of the material manufacturer 10 when generating and outputting the result of collating the above-mentioned material standard value and material test data and the material inspection record which is a document of the inspection record for each pipe. , Tag R / W13) and an operation sequence diagram quoted for explaining the flow of data and processing between the computer (server 21, DB 213) of the manufacturer 20;
Referring to FIG. 6, when outputting the collation result between the material standard value and the material test data shown in FIG. 10, first, in the material collation (S 33), in the material collation (S 33), the tag R / W 13 The material identification number and the material test data are read from the RFID tag chip 1 attached to the fixed pipe to be cut and transmitted to the server 21 of the manufacturer 20 via the server 11 of the material manufacturer 10 (S61). The server 21 collates the material standard value registered in the DB 213 searched using the received material identification number as a key and the material test data (S62, S63), generates and outputs the collation result as a document, and needs it. The display in response is as described above.

  Further, the server 11 of the material manufacturer 10 supplies the RFID tag chip 1 storing the pipe identification number and the material test data to each of the pipe cutting points (joint portions) in the material verification (S33) process shown in FIG. Duplicate one by one and paste it in the vicinity of both joints across the cut part. Furthermore, using tag R / W13, CAD data of the production parts table and piping production drawing included in the processing order information (see FIG. 8) The figure number, the product number, and the material identification number corresponding to the pipe to be cut and the joint number corresponding to each joint portion are recorded on each attached RFID tag chip 1. Thereby, the RFID tag 1 attached to both ends of the pipe includes at least the pipe identification number, the material test data, the material identification number, and the joint number.

  Further, the material manufacturer 10 uses the tag R / W 13 in advance to the inspector before the material witnessing process of step S34 shown in FIG. 3, for example, before the third party witness inspection by the customer or the like. The unique code and electronic authentication data such as password and fingerprint information registered in the wireless tag chip (not shown) are fetched and transmitted to the server 21 of the manufacturer 20 via the server 11 (S64). . Upon receiving this, the server 21 of the manufacturer 20 registers the inspector's code and electronic authentication data in the DB 213 (S65, S66). Thus, at the time of actual witness inspection, the RFID tag chip possessed by the inspector is read by the tag R / W 13 and a password is input from the terminal 12 or fingerprint information is input by a fingerprint reader or the like. The electronic authentication data can be entered, and it can be authenticated whether the person is a valid inspector.

  Then, in the material manufacturer 10, in the actual material witnessing step of step S34 shown in FIG. 3, the tag R / W 13 causes the material test data and the material identification number from the wireless tag chip 1 attached to the fixed pipe before cutting. Is transmitted to the server 21 of the manufacturer 20 via the server 11 of the material manufacturer 10 (S67), and the server 21 of the manufacturer 20 registers the material standard registered in the DB 213 searched using the received material identification number as a key. The value and the material test data are collated (S68, S69), and based on the collation result, for example, a material management record table shown in FIG. 11A is generated and displayed on the display unit 222 of the terminal 22.

  In addition, when the inspector's electronic authentication data is stored in the DB 213 in advance by the above procedure at the time of a third party inspection by a customer or other inspector, the code of the inspector is obtained from the RFID tag chip of the inspector. 11 is obtained, electronic authentication data such as a password and fingerprint information is obtained from an input means (not shown), the inspector is authenticated at the manufacturer's server 21, and the procedure of steps S67 to S69 is performed. It is possible to generate and output a material inspection record (third party organization witness) whose example is shown in (b). In the material inspection record shown in FIG. 11B, the data of “Economy Ichiro” in the item of “Inspector” includes the code of the inspector and the electronic authentication data of the inspector during the actual witness inspection. As a result of input and authentication, it is automatically input.

As a result, material inspection records are automatically generated without confirming the actual product, reducing the burden on the document creator and displaying the material standard values and verification results on the computer screen. The check time can be greatly reduced.
Further, as described above, by recording electronic authentication data such as an inspector code and a fingerprint in the DB 213 of the manufacturer 20 for the authentication of the inspector, the factor of falsification of the inspection result can be reduced. For this reason, for example, in the subsequent material confirmation inspection, it becomes possible to operate as a sampling inspection from a total inspection, and as a result, the number of times of attendance and time can be reduced.

Next, the flow of a series of production steps from bending work (S36) to finished product delivery (S42) shown in FIG. 4 will be described (refer to FIGS. 1 and 2 as appropriate). FIG. 7 is a sequence diagram cited for explaining the flow of data between the computer (server 21) of the manufacturer 20 and the tag R / W 13 at this time.
First, in the bending operation (S36), in the material manufacturer 10, using the tag R / W 13, the server 11 of the material manufacturer 10 reads the material identification number from the RFID tag chip 1 attached to the pipe to be bent. (S71), this material identification number is transmitted to the server 21 of the manufacturer 20. Receiving this material identification number, the server 21 of the manufacturer 20 searches the bending data from the DB 231 using the material identification number as a key (S72, S73). For example, the bending processing diagram shown in FIG. It transmits to the server 11 of the manufacturer 10. The bending process diagram shown in FIG. 12 is stored in advance in the DB 213 of the manufacturer 20 for each pipe to be bent.

Next, in the assembling step (S37), the material manufacturer 10 uses the tag R / W 13 to connect the server 11 of the material manufacturer 10 to the material stored in the wireless tag chip 1 attached to the mutually connected piping. The identification information and the joint number are read (S74), and the information is transmitted to the server 21 of the manufacturer 20.
The server 21 of the manufacturer 20 collates the material identification number and the joint number recorded on the RFID tag chip 1 attached to the mutual piping connected to the information of the manufacturing parts table registered in the DB 213 (S75, S76), and displays the result on the display unit 222 of the terminal 22. An example of the line assembly verification result displayed at this time is shown in FIG. In the line assembly verification result shown in FIG. 13, the item “tag position” corresponds to the code given to the wireless tag chip 1 in S <b> 37 of FIG. 4.

In addition, for example, when performing inspection inspection of a welded portion that is a joint portion, the material manufacturer 10 uses the tag R / W 13 to identify the material from the RFID tag chip 1 attached to the joint portion to be inspected of the pipe. The number and the joint number are read (S 77), and further, the inspector's electronic authentication data, which is information for identifying the inspector, is obtained from the input means (not shown), and the examination date is automatically obtained using the calendar function of the server 11. Then, these pieces of information are transmitted to the server 21 of the manufacturer 20 via the server 11.
The server 21 of the manufacturer 20 that has received these pieces of information creates a progress management table for the welding location based on the past management record for each welding location registered in the DB 213 and the electronic authentication data of the registered inspector. The screen is generated and displayed on the display unit 222 of the terminal 22 (S78, S79). An example of the progress management table displayed at this time is shown in FIG.

  As described above, since the RFID tag 1 with the material identification number input is affixed to both ends (near the welded portion) of each pipe cutting unit, the material identification number between the components is collated. A mistake can be prevented, and the progress management table can be automatically created by using it for the progress management of the welding inspection, thereby reducing the burden on the document creator. Furthermore, by registering the joint number for each joint part in the RFID tag chip 1, assembly management considering upstream and downstream of the piping can be performed, and inspection management for each joint can also be performed.

  After the assembly (S37), the non-destructive inspection (S38), the heat treatment (S39), the undercoat coating (S40), the preparation for shipment (S41), and the finished product delivery (S42) were produced as described above. Since other than using the document is the same as the conventional one, the description thereof is omitted here.

  As described above, according to the present embodiment, the computer (server 21) of the manufacturer 20 produces an optimum drawing for cutting an unprocessed standard pipe according to the dimensions to be processed based on the pipe manufacturing drawing. The processing order is generated via the network 31 based on the generated drawing and the material identification number assigned to each pipe cut based on the drawing. The computer (server 11) of the material manufacturer 10 records the assigned material identification number together with the material test data on the wireless tag chip 1 attached to each pipe cut based on the plan drawing. 20 computers (servers 21) read the material test data from the RFID tag chip 1 affixed to the pipe to be delivered and collate with the material standard value registered in the DB 213 in advance using the material identification number as a key and record The table is generated.

  Thus, the material identification number recorded in the RFID tag chip 1 can be associated with, for example, each specification of design data, processing data, and production process data. ) Management record table can be automatically generated without confirming, and the burden on workers for creating management documents created in each process can be reduced, and the time required for creation and inspection can be reduced.
