Description

  The present disclosure relates to a material management system and a material management method.

  2. Description of the Related Art In general, a material storage area for temporarily storing various materials used for construction is provided near a construction site for construction work, civil engineering work, plumbing work, or the like. Material storage is usually divided into several areas. Various materials are classified into each area according to a construction process, a material type, and the like.

  In particular, large projects such as plant construction require enormous amounts of material. There are many processes, such as shipping, unloading, and storage in a material storage area, between the time the materials are shipped and the time they are constructed at the construction site, and a number of contractors are involved in each process. Therefore, there is a need for a method for consistently managing a material movement history from shipping to construction.

  For example, Patent Documents 1 and 2 disclose that a plurality of articles with an RF tag are stored in a package and shipped, and after the package is received, the package is read from the outside of the package using a reading device. It discloses reading each RF tag in the body.

JP-A-2004-091088 JP 2006-160324 A

  However, many of the materials used at the construction site are made of metal, and the package itself may be made of metal. Radio waves transmitted and received by RF tags may be reflected or shielded by metal, so if multiple materials with RF tags are stored in a package, all RF tags can be removed from the outside of the package. It becomes difficult to read. In this case, the operation of taking out the material from the package and reading the RF tag occurs, and the management of the material may be complicated.

  Therefore, the present disclosure describes a material management system and a material management method that can efficiently manage materials.

  Example 1 A material management system according to an example of the present disclosure is a storage that stores material management data including a plurality of material information including individually assigned identification numbers and packing numbers respectively associated with the plurality of material information. A reading unit configured to be able to read an RF tag included in an RF tag component attached to each of a plurality of materials and configured to store corresponding material information; and a control unit. Is provided. The control unit controls the reading unit to read the RF tags attached to the plurality of materials housed in the package, and processes the material information corresponding to the read tag read by the reading unit. The process of updating the material management data by associating the read information, and when there is an unread tag that the reading unit could not read, searches the material management data using the package number of the read tag as a key and includes the same package number. And updating the material management data by associating the read information with the material information corresponding to the unread tag.

  In the system of the first example, as a result of the reading unit reading the RF tags of a plurality of materials contained in the package, even if there is an unread tag, the material management data can be obtained using the package number even if there is an unread tag. The information of the unread tag in is updated. That is, if the RF tag of at least one material in the package is read, it is considered that the RF tags of other materials contained in the same package are also read. Therefore, even when there are unread tags, there is no need to take out the materials from the package and read the RF tags one by one. Therefore, it is possible to efficiently manage the materials.

  Example 2. In the system of Example 1, the RF tag includes a first storage area configured to store an identification number, and a second storage area configured to store information other than the identification number. The unit further executes a process of controlling the reading unit to read information stored in the second storage area when the identification number stored in the first storage area does not exist in the material management data. May be. In this case, if the identification number of the RF tag exists in the material management data, only the identification number is read from the first storage area of the RF tag, and other information is read from the second storage area of the RF tag. Not read. Therefore, the reading process is speeded up, and the material can be managed more efficiently. On the other hand, when the identification number of the RF tag does not exist in the material management data, information other than the identification number is read from the second storage area of the RF tag. Therefore, it is possible to confirm what information is stored in the RF tag that is not present in the material management data.

  Example 3 The system of Example 1 or Example 2 further includes a writing unit configured to be able to write shipping information to an RF tag, and the control unit transmits a radio wave of an intensity set according to setting information input by an operator. A process of controlling the writing unit so that the shipping information is written in the RF tag by outputting the writing information from the writing unit may be further executed. In this case, the intensity of the radio wave can be changed according to the surrounding environment. For this reason, it is possible to more reliably write the shipping information to the RF tag even in a site where radio waves are difficult to transmit.

  Example 4. The system of Example 3 further includes a display unit configured to display various information, and the control unit displays information on the RF tag when the reading unit reads an RF tag storing shipping information. The process of controlling the display unit may be further executed as described above. In this case, information on the RF tag read by the reading unit is displayed on the display unit. Therefore, the worker can easily grasp the progress of the shipping work.

  Example 5 In any of the systems of Examples 1 to 4, the control unit updates the material management data by associating the reading date with the material information corresponding to the RF tag only when the reading unit reads the RF tag. In other cases, processing for making the reading date and time unchangeable may be further executed. In this case, although the RF tag is not read, even if the material management data is tampered with, for example, a worker manually updates the material information corresponding to the RF tag, the material management data Is not updated. Therefore, the tampering of the material management data can be easily detected by confirming the reading date and time of the material management data by another worker.

  Example 6. The system according to any one of Examples 1 to 5 further includes a display unit configured to display various information. When the reading unit reads the RF tag, the control unit transmits the RF tag together with information indicating a reading result. A process of controlling the control unit to display an input receiving unit for transitioning to an update screen for updating information of the material management data corresponding to the tag may be further executed. In this case, for example, in the search operation of the material by the reading unit, when the RF tag of the material being searched is read, an input reception unit (for example, an update button) is displayed on the display unit together with the search result. Therefore, when the operator operates the input reception unit, it is possible to immediately transition to an update screen for updating the material management data corresponding to the RF tag. Therefore, materials can be managed more efficiently.

  Example 7 The system according to any one of Examples 1 to 6 includes a code reading unit configured to be capable of reading a corresponding code provided on an RF tag component so as to correspond to material information and to be visually identifiable, The apparatus further includes a writing unit configured to be capable of writing material information, wherein the control unit writes the material information corresponding to the corresponding code read by the code reading unit to the RF tag when the code reading unit reads the corresponding code. May be further executed to control the writing unit. In this case, the same information as the information of the corresponding code provided in the RF tag component is reliably written in the RF tag. Therefore, it is possible to more efficiently perform the manufacturing operation of the RF tag component.

  Example 8 In any of the systems of Examples 1 to 7, the process of updating the material management data by associating the read information with the read information is performed by the operator as material information corresponding to the read tag read by the reading unit. A process for updating the material management data in association with the input information may be included. In this case, the information input by the worker is recorded in the material management data at the timing when the reading unit reads the RF tag. That is, the RF tag reading process and the information recording process can be performed substantially simultaneously. Therefore, it is possible to more efficiently perform the manufacturing operation of the RF tag component.

  Example 9 A material management method according to another example of the present disclosure is to prepare material management data including a plurality of material information including individually assigned identification numbers and packaging numbers respectively associated with the plurality of material information. And an RF tag included in an RF tag component attached to each of a plurality of materials housed in the package, the RF tag being configured to be able to store the corresponding material information by a reader. Reading, updating the material management data by associating the read information with the material information corresponding to the read tag read by the reader, and reading if there is an unread tag that the reader could not read. The material management data is searched using the package number stored in the tag as a key, and the material information including the same package number and corresponding to the unread tag is associated with the read information to manage the material. And updating the over data. In this case, the same operation and effect as those of the system of Example 1 are obtained.

  According to the material management system and the material management method according to the present disclosure, it is possible to efficiently manage materials.

  Next, an outline of a method of managing the material M by the material management system 1 will be described with reference to FIG. First, the manufacturing system 100 performs a process of manufacturing the RF tag component 2 (see step S1). Next, the packing / shipping system 200 performs a process of reading / writing to / from the RF tag 2a through the portable terminal 20 and the reader 30 to update the packing / shipping information of the material management data D (see step S2).

  Next, the arrival inspection system 300 reads from the RF tag 2a through the mobile terminal 20 and the reader 30, and updates the arrival information of the material management data D (see step S3).

The update processing of the storage information by the storage management system 400 may be performed at any time when the storage of the material M is changed.

Details of each of the systems 100 to 600 will be described below.

[RF tag component manufacturing system]
Next, the configuration of the manufacturing system 100 will be described with reference to FIGS. As shown in FIG. 5, the manufacturing system 100 includes an information processing device 10, a printing machine 110, a laminator 120, and a reader / writer 130 (writing unit).

  The information processing apparatus 10 is configured to transmit material information of the material management data D to the printing press 110. The printing press 110 prints the material information received from the information processing device 10 on the surface of the storage member 2b. The printing press 110 may, for example, print the corresponding code C corresponding to the material information on the storage member 2b, or may print the character information corresponding to the material information on the storage member 2b. The corresponding code C is not particularly limited as long as it is optically readable. The corresponding code C may be, for example, a two-dimensional code or a barcode.

  The laminator 120 is configured to seal the RF tag 2a stored in the printed storage member 2b with the waterproof film 2c. For example, as shown in FIG. 5, the RF tag 2a is sandwiched by the storage member 2b such that the RF tag 2a is located inside the storage member 2b folded in half at the center. Therefore, the RF tag 2a is completely covered by the storage member 2b. The storage member 2b for storing the RF tag 2a is inserted into the laminator 120 while being sandwiched between the waterproof films 2c so as to be completely covered from both sides by the waterproof film 2c. The laminator 120 heats the waterproof film 2c to fuse the waterproof films 2c to each other. Thereby, the RF tag component 2 is formed. Here, the waterproof film 2c has such a light transmissivity that the printed contents of the storage member 2b located inside can be visually recognized in appearance.

  Here, the RF tag 2a includes a plurality of storage areas as shown in FIG. Specifically, the RF tag 2a includes a Reserved section A1, a TID section A2, an EPC section A3 (first storage area), and a User section A4 (second storage area).

  The reserved part A1 stores, for example, an access password used when accessing the RF tag 2a. The TID unit A2 is configured to store a unique number for the RF tag 2a when the RF tag 2a is manufactured, for example. After the unique number is written in the TID section A2, the state of the TID section A2 may be changed to a read-only state in which information cannot be rewritten.

  The EPC unit A3 is configured to store the identification number of the corresponding material M. The EPC unit A3 may be configured to read and write information at a higher speed than the User unit A4. The User section A4 is configured to store, for example, material information other than the identification number and shipping packing information. The EPC unit A3 and the User unit A4 may be readable and writable in order to reuse the collected RF tag 2a.

  As shown in FIG. 5, the reader / writer 130 includes a reader 131 (code reader), an information processing device 132, and a writer 133 (writer). The reader 131 is configured to image the corresponding code C provided on the RF tag component 2. The information processing device 132 is configured to perform image processing on the image captured by the reader 131 and acquire (decode) information held by the corresponding code C.

  The writer 133 is configured to write the material information decoded from the corresponding code C by the information processing device 132 to the RF tag 2a of the RF tag component 2 placed or located in the vicinity. Specifically, the writer 133 writes the identification number of the material information into the EPC unit A3, and writes the material information other than the identification number into the User unit A4.

  Next, a method of manufacturing the RF tag component 2 by the manufacturing system 100 will be described with reference to FIG. First, the operator operates the information processing apparatus 10 to transmit material information of the material management data D stored in the storage unit 13 to the printing press 110. The printing press 110 prints the corresponding code C and character information corresponding to the received material information on the storage member 2b (see step S11).

  Next, an operator performs an operation of storing the RF tag 2a in the storage member 2b and an operation of inserting the RF tag 2a into the laminator 120 while sandwiching the RF tag 2a with the waterproof film 2c. Thereby, the RF tag component 2 is manufactured (see step S12). Next, when the operator places the RF tag component 2 on the writer 133 of the reader / writer 130, the reader 131 images the corresponding code C (see step S13).

  The image of the corresponding code C captured by the reader 131 is transmitted from the reader 131 to the information processing device 132. The information processing device 132 decodes the captured image and acquires the material information held by the corresponding code C. The information processing device 132 transmits the decoded material information to the writer 133. The writer 133 writes the material information received from the information processing device 132 into the RF tag 2a of the placed RF tag component 2 (see step S14). As a result, a plurality of RF tag components 2 having material information corresponding to each material M are manufactured.

[Package shipping system]
Next, the configuration of the packaging and shipping system 200 will be described with reference to FIGS. As shown in FIG. 8, the packing and shipping system 200 includes the information processing device 10, the mobile terminal 20, and the reader 30.

  The information processing device 10 is configured to transmit the material management data D to the mobile terminal 20. Before the transmission of the material management data D, the worker may input the planned shipping date and the planned arrival date to the material management data D on the information processing device 10. The information processing device 10 is configured to receive the material management data D updated in the mobile terminal 20 from the mobile terminal 20.

  The mobile terminal 20 is configured to display a screen B1 as shown in FIG. 9 on the display unit 24, for example, and to be able to accept input from an operator. For example, the mobile terminal 20 can receive an input of a part of the packing and shipping information (shipping date, person in charge of shipping, and packing number).

  The mobile terminal 20 is configured to communicate with the reader 30 to control the reader 30 and read an identification number from the RF tag 2 a of the RF tag component 2 attached to the material M through the reader 30. Upon acquiring the identification number, the portable terminal 20 is configured to update the material management data D by associating the package shipping information input through the display unit 24 with the identification number.

  Here, an example of updating the material management data D will be described. In the example of FIG. 9, the shipping date (September 14, 2017), the person in charge (Suzuki), and the package number (091902) are input in advance to the mobile terminal 20 as the package shipping information. Therefore, when the portable terminal 20 acquires the identification number (for example, 101) from the RF tag 2a through the reader 30 in this state, the packing shipping information (shipping date (September 14, 2017) ), The person in charge (Suzuki) and the package number (091902)) are associated with each other, and the material management data D is updated (see FIG. 10).

  When the mobile terminal 20 acquires the identification number, the mobile terminal 20 may be configured to write the package shipping information input through the display unit 24 to the RF tag 2a through the reader 30. The packing and shipping information may be written in the User section A4, for example.

  Next, a method of packing and shipping the material M in the packing and shipping system 200 will be described with reference to FIG. First, for example, the worker checks the character information displayed on the storage member 2b, and attaches the RF tag components 2 to the corresponding materials M one by one (see step S21). Next, the worker operates the information processing device 132 to input the planned shipping date and the planned receiving date into the material management data D (see step S22).

  Next, the worker operates the information processing apparatus 10 to transmit the material management data D in which the planned shipping date and the planned receiving date are input to the mobile terminal 20 (see step S23). The mobile terminal 20 stores the material management data D in the storage unit 23.

  Next, the worker inputs predetermined packing shipping information (for example, shipping date, person in charge, packing number) to the mobile terminal 20 through the display unit 24 of the mobile terminal 20 (see step S24). Next, the portable terminal 20 reads the identification number stored in the RF tag 2a through the reader 30. Next, the portable terminal 20 writes the package shipping information input to the portable terminal 20 at the time of reading the identification number into the RF tag 2a from which the identification number has been read, and writes the packing shipping information to the portable terminal 20 at the time of reading the identification number. The material management data D is updated by associating the input package shipping information with the identification number (see step S25). At this time, the process of reading the identification number and the process of updating the material management data D may be performed while changing the packing / shipping information input to the mobile terminal 20 according to the material M to be read.

  When the reading of the identification numbers of the RF tags 2a and the writing of the packing shipment information to the RF tags 2a are completed for all the target materials M, the operator removes the materials M having the same packing number. It is stored in the same package B, and the package B is shipped to a construction site. Thereafter, the mobile terminal 20 transmits the updated material management data D to the information processing device 10 (see step S26). The information processing device 10 stores the material management data D in the storage unit 13. Thereafter, the worker stores the materials M with the same package number in the same package B and ships them to the construction site.

[Material arrival inspection system]
Subsequently, the configuration of the arrival inspection system 300 will be described with reference to FIGS. The arrival inspection system 300 includes an information processing device 10, a portable terminal 20, and a reader 30, as shown in FIG.

  The information processing device 10 is configured to transmit the material management data D to the mobile terminal 20. The information processing device 10 is configured to receive the material management data D updated in the mobile terminal 20 from the mobile terminal 20.

  The mobile terminal 20 is configured to display, for example, a screen B2 as shown in FIG. 13 on the display unit 24 so as to be able to receive an input from an operator. For example, the mobile terminal 20 can receive input of a part of the arrival information (arrival date and person in charge of arrival) and a part of the storage information (storage number).

  The mobile terminal 20 is configured to communicate with the reader 30 to control the reader 30 and read an identification number from the RF tag 2 a of the RF tag component 2 attached to the material M through the reader 30. At this time, the reading process may be performed in a state where the plurality of materials M are packed in the packing body B. Upon acquiring the identification number, the mobile terminal 20 updates the material management data D by associating the arrival information and the yard information input through the display unit 24 with the identification number. Further, the mobile terminal 20 is configured to update the material management data D by associating the confirmation date indicating the date and time when the reading by the reader 30 was performed with the identification number. As the confirmation date, for example, the current date and time on the system of the mobile terminal 20 and the current date and time acquired from the network may be used.

  Here, an example of updating the material management data D will be described. In the example of FIG. 13, the date of arrival (September 21, 2017), the person in charge (Sato), and the yard number (01) are input in the mobile terminal 20 in advance. Therefore, when the portable terminal 20 acquires the identification number (for example, 101) from the RF tag 2a through the reader 30 in this state, the arrival date (September 21, 2017) is assigned to the identification number “101”. The material management data D is updated so that the person (Sato), the confirmation date (September 21, 2017), and the storage number (01) are associated with each other (see FIG. 14).

  At this time, the same date as the arrival date input to the mobile terminal 20 may be recorded on the confirmation date of the storage information. Similarly, the same person in charge as the person in charge input to the mobile terminal 20 may be recorded as the person in charge of the storage information. Thus, the information on the initial storage of the material M can be updated at the same timing using the information at the time of arrival.

  Next, an incoming inspection method for the material M in the incoming inspection system 300 will be described with reference to FIG. First, the operator operates the information processing apparatus 10 to transmit the material management data D updated in step S25 to the mobile terminal 20 (see step S31). The mobile terminal 20 stores the material management data D in the storage unit 23.

  Next, the worker inputs predetermined arrival information (for example, arrival date, person in charge of arrival) and predetermined yard information (eg, yard number) to the mobile terminal 20 through the display unit 24 of the mobile terminal 20. (See step S32). Next, the portable terminal 20 reads the identification number stored in the RF tag 2a through the reader 30. The mobile terminal 20 updates the material management data D by associating the information input to the mobile terminal 20 at the time of reading the identification number with the identification number (see step S33).

  Next, the portable terminal 20 refers to the material management data D and determines whether or not the RF tag 2a that cannot be read exists. If the mobile terminal 20 determines that the RF tag 2a that could not be read does not exist (NO in step S34), since all the RF tags 2a have been read, the updated material management data D is stored in the information processing device 10 (See step S36). The information processing device 10 stores the material management data D in the storage unit 13.

  On the other hand, if reading of the RF tags 2a is performed in a state where the plurality of materials M are packed in the packing body B, not all of the RF tags 2a may be read. Therefore, when the mobile terminal 20 determines that the RF tag 2a that cannot be read exists (YES in step S34), the mobile terminal 20 updates the information about the RF tag 2a that cannot be read using the information of the read RF tag 2a. (See step S35).

  The example in FIG. 14 indicates that the RF tag 2a holding the identification number 103 could not be read. In this case, using the package number "091901" associated with the identification number "103" as a key, the identification number of another read RF tag 2a having the matching package number is searched. In the example of FIG. 14, when the same package number “091901” is included in the material management data D, the same information as the arrival information and the yard information associated with the package number “091901” (for example, the arrival The confirmation date of the information (September 21, 2017), the storage number (01), the person in charge of the storage information (Sato), and the confirmation date of the storage information (September 21, 2017) are changed to the identification number “103”. Update in association.

  After step S35, the same processing as step S36 described above is performed.

  The mobile terminal 20 communicates with the reader 30 to control the reader 30 to read the identification number through the reader 30 from the RF tag 2 a of the RF tag component 2 attached to the material M to be changed. It is configured. Upon acquiring the identification number, the mobile terminal 20 updates the material management data D by associating the storage information input through the display unit 24 with the identification number. If the storage information is already stored in the material management data D, it is overwritten using the new storage information input through the display unit 24.

  Here, an example of updating the material management data D will be described. In the example of FIG. 17, the confirmation date (September 23, 2017), the person in charge (Takahashi), and the storage number (02) are input to the mobile terminal 20 in advance. Therefore, when the portable terminal 20 acquires the identification number (for example, 101) from the RF tag 2a through the reader 30 in this state, the confirmation date (September 23, 2017) is assigned to the identification number "101". The material management data D is updated so that the person (Takahashi) is associated with the storage number (02) (see FIG. 18).

  Next, a method of managing the place of the material M in the place management system 400 will be described with reference to FIG. First, the operator operates the information processing apparatus 10 to transmit the material management data D updated in step S36 to the mobile terminal 20 (see step S41). The mobile terminal 20 stores the material management data D in the storage unit 23.

  Next, the worker inputs predetermined place information (for example, confirmation date, person in charge, place number) to the portable terminal 20 through the display unit 24 of the portable terminal 20 (see step S42). Next, the portable terminal 20 reads the identification number stored in the RF tag 2a through the reader 30. The mobile terminal 20 updates the material management data D by associating the information input to the mobile terminal 20 at the time of reading the identification number with the identification number (see step S43).

  Next, the worker transports the material M whose storage space is to be changed to a new storage space (see step S44). After the transport and installation of the material M to the new storage place are completed, the mobile terminal 20 transmits the updated material management data D to the information processing device 10 (see step S45). The information processing device 10 stores the material management data D in the storage unit 13.

Subsequently, the configuration of the construction management system 500 will be described with reference to FIGS. The construction management system 500 includes an information processing device 10, a mobile terminal 20, and a reader 30, as shown in FIG.

  The information processing device 10 is configured to transmit the material management data D to the mobile terminal 20. The information processing device 10 is configured to receive the material management data D updated in the mobile terminal 20 from the mobile terminal 20.

  The mobile terminal 20 is configured to display a screen B4 as shown in FIG. 21 on the display unit 24, for example, so as to be able to receive an input from an operator. For example, the mobile terminal 20 can receive an input of a part of the construction information (a confirmation date and a person in charge of the construction).

  The mobile terminal 20 is configured to communicate with the reader 30 to control the reader 30 and read an identification number from the RF tag 2 a of the RF tag component 2 attached to the material M to be installed through the reader 30. ing. When acquiring the identification number, the mobile terminal 20 updates the material management data D by associating the information input through the display unit 24 with the identification number.

  Here, an example of updating the material management data D will be described. In the example of FIG. 21, the confirmation date (November 5, 2017) and the person in charge (Tanaka) have been input to the mobile terminal 20 in advance. Therefore, when the mobile terminal 20 acquires the identification number (for example, 101) from the RF tag 2a through the reader 30 in this state, the identification number “101” is assigned a confirmation date (November 5, 2017), The material management data D is updated so as to be associated with the person (Tanaka) (see FIG. 22). At this time, the material management data D may be updated so that “construction completed” is input as the construction status in the construction information.

  Next, a construction management method for the material M in the construction management system 500 will be described with reference to FIG. First, the operator operates the information processing apparatus 10 to transmit the material management data D updated in step S44 (if the storage management processing of the material M is not performed, step S36) to the mobile terminal 20. (Refer to step S51). The mobile terminal 20 stores the material management data D in the storage unit 23.

  Next, the worker inputs predetermined construction information (for example, a construction confirmation date, a person in charge of confirmation) to the portable terminal 20 through the display unit 24 of the portable terminal 20 (see step S52). Next, the portable terminal 20 reads the identification number stored in the RF tag 2a through the reader 30. The mobile terminal 20 updates the material management data D by associating the information input to the mobile terminal 20 at the time of reading the identification number with the identification number (see step S53).

  Next, the worker performs construction work using the material M to be constructed (see step S54). After the construction work of the material M is completed, the mobile terminal 20 transmits the updated material management data D to the information processing device 10 (see step S55). The information processing device 10 stores the material management data D in the storage unit 13.

[RF tag collection system]
Subsequently, the configuration of the collection system 600 will be described with reference to FIGS. As illustrated in FIG. 24, the collection system 600 includes the information processing device 10, the mobile terminal 20, and the reader 30.

  The information processing device 10 is configured to transmit the material management data D to the mobile terminal 20. The information processing device 10 is configured to receive the material management data D updated in the mobile terminal 20 from the mobile terminal 20.

  The mobile terminal 20 is configured to display, for example, a screen B5 as shown in FIG. 25 on the display unit 24 so as to be able to receive input from an operator. For example, the mobile terminal 20 can receive input of collection information.

  The mobile terminal 20 is configured to communicate with the reader 30 to control the reader 30 and read out the identification number from the RF tag 2 a of the RF tag component 2 to be collected through the reader 30. When acquiring the identification number, the mobile terminal 20 updates the material management data D by associating the information input through the display unit 24 with the identification number.

  Here, an example of updating the material management data D will be described. In the example of FIG. 25, the collection date (November 6, 2017) and the person in charge (Watanabe) are input in the mobile terminal 20 in advance. Therefore, when the portable terminal 20 acquires the identification number (for example, 101) from the RF tag 2a through the reader 30 in this state, the collection date (November 6, 2017) is assigned to the identification number “101”. The material management data D is updated so as to be associated with the person (Watanabe) (see FIG. 26).

  Next, a method of collecting the RF tag 2a in the collection system 600 will be described with reference to FIG. First, the operator operates the information processing apparatus 10 to transmit the material management data D updated in step S54 to the mobile terminal 20 (see step S61). The mobile terminal 20 stores the material management data D in the storage unit 23.

  Next, the worker inputs predetermined collection information (for example, collection date, person in charge) to the mobile terminal 20 through the display unit 24 of the mobile terminal 20 (see step S62). Next, the portable terminal 20 reads the identification number stored in the RF tag 2a through the reader 30. The mobile terminal 20 updates the material management data D by associating the information input to the mobile terminal 20 at the time of reading the identification number with the identification number (see step S63).

  Next, the mobile terminal 20 transmits the updated material management data D to the information processing device 10 (see step S64). The information processing device 10 stores the material management data D in the storage unit 13. Thereafter, the worker takes out the RF tag 2a from the RF tag component 2 (see step S65).

  Specifically, the waterproof film 2c is cut together with the storage member 2b using scissors or the like. At this time, since the position of the RF tag 2a can be confirmed from the touch, swelling, sheer feeling, and the like of the RF tag component 2, cutting of the RF tag 2a can be avoided.

  Next, the RF tag 2a is taken out from the opening formed by the cutting. At this time, if the inner surface of the storage member 2b is a non-adhesive surface, the RF tag 2a slides out of the storage member 2b only by tilting the opening downward, so that the RF tag 2a can be collected extremely easily. Becomes The storage member 2b may be made of, for example, paper, a resin film, cloth, a rubber sheet, or the like.

[Action]
In the present embodiment as described above, as a result of the portable terminal 20 reading the RF tags 2a of the plurality of materials M housed in the package B through the reader 30, there is an unread tag. Also, the information of the unread tag in the material management data D is updated using the package number. That is, when the RF tag 2a of at least one material M in the package B is read, it is considered that the RF tag 2a of another material M stored in the same package B is also read. Therefore, even when there is an unread tag, there is no need to take out the material M from the package B and read the RF tags one by one. Therefore, it is possible to efficiently manage the material M.

  In the present embodiment as described above, the corresponding code C of the RF tag component 2 placed on the writer 133 of the reader / writer 130 is read by the reader 131 of the reader / writer 130 and held by the corresponding code C. Material information is decoded through image processing. After that, the decoded material information is written into the RF tag 2a by the writer 133. Therefore, the same information as the information of the corresponding code C provided in the RF tag component 2 is reliably written in the RF tag 2a. Therefore, it is possible to more efficiently perform the manufacturing operation of the RF tag component 2. Further, the reading of the corresponding code C by the reader 131 and the writing to the RF tag 2a by the writer 133 are performed very close in time (for example, within several seconds). Therefore, it becomes possible to manufacture the RF tag component 2 more efficiently.

  In the present embodiment as described above, in each of the systems 200 to 600, the information input by the worker is associated with the identification number read by the mobile terminal 20 through the reader 30, and the material management data D is updated. . Therefore, the information input by the worker is recorded in the material management data D at the timing when the mobile terminal 20 reads the RF tag 2a. That is, the reading process of the RF tag 2a and the information recording process can be performed substantially simultaneously. Therefore, the manufacturing operation of the RF tag component 2 can be performed more efficiently.

[Modification]
As described above, the embodiments according to the present disclosure have been described in detail. However, various modifications may be added to the above embodiments within the scope of the present invention.

  (1) The portable terminal 20 reads the identification number stored in the EPC unit A3 of the RF tag 2a through the reader 30, and when the identification number is present in the material management data D, the portable terminal 20 The reader 30 may not read material information other than the identification number stored in the User section A4 of the RF tag 2a. In this case, the reading process is speeded up, so that the material M can be managed more efficiently.

  On the other hand, when the portable terminal 20 reads the identification number stored in the EPC unit A3 of the RF tag 2a through the reader 30, but the identification number does not exist in the material management data D, the portable terminal 20 Alternatively, material information other than the identification number stored in the User section A4 of the RF tag 2a may be read through the reader 30. Material information other than the read identification number may be displayed on the display unit 24. In this case, it is possible for an operator to confirm what information is stored in the RF tag 2a that is not present in the material management data D.

  (2) As shown in FIG. 9, FIG. 13, FIG. 17, FIG. 21, and FIG. 25, the operator may be able to change the radio wave intensity for reading and writing the RF tag 2a through the display unit 24 ( (See arrow E1). In this case, reading / writing of the RF tag 2a is performed according to the magnitude of the radio wave intensity input by the operator. Therefore, the intensity of the radio wave can be changed according to the surrounding environment. Therefore, even at a construction site where radio waves are difficult to transmit, it is possible to more reliably read and write various information to the RF tag 2a.

  (3) As shown in FIGS. 9, 13, 17, 21, and 25, when the portable terminal 20 reads the identification number of the RF tag 2 a through the reader 30, the identification number in the material management data D Information associated with the number may be displayed on the display unit 24 (see arrow E2). Alternatively, the total number of read RF tags 2a may be displayed on the display unit 24 (see arrow E3). In this case, information about the RF tag 2a read by the mobile terminal 20 is displayed on the display unit 24. Therefore, it is possible for the worker to easily grasp the progress of various works.

  (4) As shown in FIG. 28, when the portable terminal 20 reads the identification number of the RF tag 2a through the reader 30, the material management data D is updated by associating the identification number with the last read date and time. In this case, the last reading date and time may not be updated (see arrow E4). In FIG. 28, the state where the last read date and time is locked is indicated by hatching. In this case, even though the RF tag 2a is not read, even if a certain worker falsifies the material management data D, such as manually updating material information corresponding to the RF tag 2a, The last read date and time of the material management data D is not updated. Therefore, the tampering of the material management data D can be easily detected by confirming the last read date and time of the material management data D by another worker.

  (5) For example, when searching for a predetermined material M using the portable terminal 20, the screen B6 as shown in FIG. May be presented. When the material M is found as a result of the search, the search result may be presented to the operator by displaying a screen B7 as shown in FIG. As shown in FIG. 29B, the screen B7 may include the input receiving unit G. The input receiving unit G may be, for example, a button-shaped GUI displayed as “data update”. When the operator operates the input receiving unit G, a screen B8 as shown in FIG. 30 may be displayed on the display unit 24. The screen B8 is an update screen for updating various information corresponding to the material M found by the search. That is, when the input receiving unit G is operated by the worker, the screen transitions from the screen B7 to the screen B8. In this case, for example, in the search operation of the material M by the portable terminal 20, when the RF tag 2a of the material M being searched is read, the input receiving unit G is displayed on the display unit 24 together with the screen B7 indicating the read result. Therefore, when the operator operates the input receiving unit G, it is possible to immediately transition to the screen B8 for updating the material management data D corresponding to the RF tag 2a. Therefore, the material M can be managed more efficiently.

  (6) The information processing devices 10 constituting each of the systems 100 to 600 may be different information processing devices 10. Two or more of the systems 100 to 600 may share the same information processing device 10.

  (7) The function of the information processing device 10 may be realized by the mobile terminal 20. That is, the material management system 1 may not include the information processing device 10.

  (8) The function of the reader 30 may be realized by the mobile terminal 20. That is, the material management system 1 does not need to include the reader 30.

  (9) When recording various dates (for example, shipping date, arrival date, confirmation date, and collection date) in the material management data D, time information may also be recorded in the material management data D. That is, the date and time may be recorded in the material management data D as various dates.
