Description

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

2. Description of the Related Art In the vicinity of construction sites such as building construction, civil engineering work, plumbing construction, etc., generally, material storage areas for temporarily storing various materials used in construction are provided. A stockyard is usually divided into multiple areas. Various materials are classified in each area according to the construction process, the type of material, and the like.

In particular, a large-scale project such as plant construction requires a huge amount of materials. Many processes, such as shipping, unloading, and storage in a material storage area, exist between the shipment of materials and the construction at the construction site, and many contractors are involved in each process. Therefore, there is a demand for a method for consistently managing the movement history of materials from shipping to construction.

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

Japanese Patent Application Laid-Open No. 2004-091088 JP 2006-160324 A

However, many of the materials used at construction sites are made of metal, and the package itself may also be made of metal. Radio waves sent and received by RF tags may be reflected or blocked by metal, so if multiple materials with RF tags attached are contained in a package, all RF tags can be removed from the outside of the package. difficult to read. In this case, the work of taking out the material from the package and reading the RF tag is required, which may complicate the management of the material.

Therefore, the present disclosure describes a materials management system and a materials management method capable of efficiently managing materials.

Example 1. A material management system according to one 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 RF tags included in RF tag parts respectively attached to a plurality of materials and configured to store corresponding material information; a control unit; Prepare. The control unit controls the reading unit to read the RF tags attached to the plurality of materials contained in the package, and the material information corresponding to the read tags read by the reading unit, If there is a process to update the material management data by associating the read information, and if there is an unread tag that the reading unit could not read, the material management data is searched using the package number of the read tag as a key, and the Also, the material information corresponding to the unread tag is associated with the read information to update the material management data.

In the system of Example 1, as a result of the reader reading the RF tags of a plurality of materials housed inside the package, even if there are unread tags, the package number is used to read the material management data. The information of unread tags in is updated. That is, if the RF tag of at least one material in the package is read, it is assumed that the RF tags of the other materials contained in the same package have also been read. Therefore, even if 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 becomes possible to manage materials efficiently.

Example 2. In the system of Example 1, the RF tag includes a first storage area configured to store an identification number, a second storage area configured to store information other than the identification number, and a control The unit further executes processing for controlling the reading unit to read the information stored in the second storage area when the identification number stored in the first storage area does not exist in the materials management data. You may In this case, if the identification number of the RF tag exists in the materials 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, since the reading process is speeded up, it becomes possible to manage materials more efficiently. On the other hand, when the identification number of the RF tag does not exist in the materials 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 kind of information is stored in the RF tag that is assumed not to exist in the materials 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 the RF tag, and the control unit emits radio waves with an intensity set according to the setting information input by the operator. A process of controlling the writing section to output from the writing section and write the shipping information to the RF tag may be further executed. In this case, the intensity of radio waves can be changed according to the surrounding environment. Therefore, even in a site where radio waves are difficult to transmit, it is possible to write shipping information to the RF tag more reliably.

Example 4. The system of Example 3 further comprises a display unit capable of displaying various types of information, and when the reading unit reads an RF tag storing shipping information, the control unit displays information about the RF tag. A process for controlling the display unit may be further executed. In this case, information about 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 one of the systems of Examples 1 to 4, only when the reading unit reads the RF tag, the control unit associates the reading date and time with the material information corresponding to the RF tag, updates the material management data, and updates the material management data. In other cases, a process of making the reading date and time unchangeable may be further executed. In this case, even if the material management data is tampered with, for example, by manually updating the material information corresponding to the RF tag, even though the RF tag has not been read, the material management data is not updated. Therefore, by checking the read date and time of the material management data by another worker, it is possible to easily discover falsification of the material management data.

Example 6. The system of any one of Examples 1 to 5 further includes a display unit configured to be able to display various information, and when the reading unit reads the RF tag, the control unit displays the RF tag together with information indicating the 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 material management data corresponding to the tag may be further executed. In this case, for example, in searching for materials by the reading unit, when the RF tag of the material being searched is read, the search result and the input reception unit (for example, update button) are displayed on the display unit. Therefore, when the operator operates the input reception unit, the screen can be immediately changed to the update screen for updating the material management data corresponding to the RF tag. Therefore, it becomes possible to manage materials more efficiently.

Example 7. The system of any one of Examples 1 to 6 includes a code reading unit configured to read a corresponding code provided on the RF tag part so as to correspond to the material information and be identifiable in appearance, and the RF tag A writing unit configured to be able to write material information is further provided, and when the code reading unit reads the corresponding code, the control unit writes the material information corresponding to the corresponding code read by the code reading unit to the RF tag. A process for controlling the writing unit may be further executed. In this case, the same information as that of the corresponding code provided on the RF tag component is reliably written to the RF tag. Therefore, it becomes possible to perform the manufacturing work of the RF tag component more efficiently.

Example 8. In any of the systems of Examples 1 to 7, the process of associating the read information and updating the material management data is to add the material information corresponding to the read tag read by the reading unit as the read information by the worker. It may include a process of associating the input information and updating the material management data. In this case, the information input by the worker is recorded in the materials management data at the timing when the reader reads the RF tag. That is, the RF tag reading process and the information recording process can be performed substantially simultaneously. Therefore, it becomes possible to perform the manufacturing work of the RF tag component more efficiently.

Example 9. A material management method according to another example of the present disclosure prepares 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. and an RF tag included in an RF tag component attached to each of a plurality of materials housed inside the package, the RF tag configured to be capable of storing corresponding material information, by a reader. reading, linking the read information to the material information corresponding to the read tag read by the reader and updating the material management data, and if there is an unread tag that the reader could not read, the read retrieving the material management data using the package number stored in the tag as a key, and updating the material management data by associating the read information with the material information containing the same package number and corresponding to the unread tag. . In this case, the same effects as those of the system of Example 1 are obtained.

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

[Manufacturing system for RF tag parts]
Next, the configuration of the manufacturing system 100 will be described with reference to FIGS. 5 and 6. FIG. The manufacturing system 100 includes an information processing device 10, a printer 110, a laminator 120, and a reader/writer 130 (writing unit), as shown in FIG.

The information processing device 10 is configured to transmit the material information of the material management data D to the printer 110 . The printer 110 prints the material information received from the information processing device 10 on the surface of the storage member 2b. The printer 110 may print, for example, the corresponding code C corresponding to the material information on the storage member 2b, or may print 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 bar code.

The laminator 120 is configured to seal the RF tag 2a housed in the printed housing 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 so as to be positioned inside the storage member 2b that is folded in half at the center. Therefore, the RF tag 2a is completely covered with the housing member 2b. The storage member 2b for storing the RF tag 2a is put into the laminator 120 while being sandwiched between the waterproof films 2c so as to be completely covered from both sides by the waterproof films 2c. The laminator 120 heats the waterproof film 2c to fuse the waterproof films 2c. Thus, the RF tag component 2 is formed. Here, the waterproof film 2c has such a light transmittance that the contents printed on the storage member 2b located inside can be visually recognized from the outside.

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

The reserved section A1 stores, for example, an access password used when accessing the RF tag 2a. The TID section A2 is configured, for example, to store a number unique to the RF tag 2a when the RF tag 2a is manufactured. After the unique number is written in the TID section A2, the information in the TID section A2 may be put into a read-only state in which rewriting is not possible.

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

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

The writer 133 is configured to write 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 nearby. Specifically, the writer 133 writes the identification number of the material information to the EPC section A3, and writes the material information other than the identification number to the User section 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 device 10 to transmit the material information of the material management data D stored in the storage unit 13 to the printing machine 110 . The printer 110 prints the corresponding code C and character information corresponding to the received material information on the storage member 2b (see step S11).

Next, the operator performs the task of storing the RF tag 2a in the storing member 2b and the task of putting it into the laminator 120 while sandwiching it between the waterproof films 2c. Thus, 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 takes an image of the corresponding code C (see step S13).

A captured 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. FIG. 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 to 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.

[Material packing and shipping system]
Next, the configuration of the packing and shipping system 200 will be described with reference to FIGS. 8 to 10. FIG. The packing and shipping system 200 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 . Before sending the material management data D, the worker may input the scheduled shipping date and the scheduled arrival date to the material management data D on the information processing device 10 . The information processing device 10 is configured to receive the materials 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, for example, on the display unit 24 and receive input from the operator. For example, the mobile terminal 20 can accept input of part of the packing and shipping information (shipping date, shipping person in charge, and packing number).

The mobile terminal 20 is configured to communicate with the reader 30 to control the reader 30 and read the identification number from the RF tag 2a of the RF tag part 2 attached to the material M through the reader 30 . The mobile terminal 20 is configured to update the material management data D by associating the packing and shipping information input through the display unit 24 with the identification number when the identification number is acquired.

Here, an example of updating the material management data D will be described. In the example of FIG. 9, the date of shipment (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/shipment information. 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 packaging and shipping information (shipment date (September 14, 2017) is obtained for the identification number "101". ), the person in charge (Suzuki), and the package number (091902)) are associated with each other (see FIG. 10).

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

Next, a method for packing and shipping the material M in the packing and shipping system 200 will be described with reference to FIG. 11 . First, for example, the operator confirms the character information displayed on the storage member 2b, and attaches the RF tag parts 2 to the corresponding materials M one by one (see step S21). Next, the worker operates the information processing device 132 to input the scheduled shipping date and the scheduled receiving date into the materials management data D (see step S22).

Next, the worker operates the information processing device 10 to transmit the material management data D in which the scheduled shipping date and the scheduled arrival date are input to the portable terminal 20 (see step S23). The portable terminal 20 stores the materials management data D in the storage unit 23 .

Next, the worker inputs predetermined packing and 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. FIG. Next, the mobile terminal 20 writes the packing and shipping information input to the mobile terminal 20 when reading the identification number to the RF tag 2a from which the identification number was read, and writes the information to the mobile terminal 20 when reading the identification number. The input packing and shipping information is associated with the identification number, and the material management data D is updated (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 and shipping information to be input to the portable terminal 20 according to the material M to be read.

After reading the identification numbers of the RF tags 2a and writing the packing and shipping information to the RF tags 2a for all the target materials M, the worker selects the materials M with the same packing number. They are stored in the same package B, and the package B is shipped to the construction site. After that, the portable terminal 20 transmits the updated materials management data D to the information processing device 10 (see step S26). The information processing device 10 stores the materials management data D in the storage unit 13 . After that, the worker puts the materials M with the same package number in the same package B and ships them to the construction site.

[Material receipt inspection system]
Next, the configuration of the incoming goods inspection system 300 will be described with reference to FIGS. 12 to 14. FIG. The incoming goods inspection system 300 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 materials management data D updated in the mobile terminal 20 from the mobile terminal 20 .

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

The mobile terminal 20 is configured to communicate with the reader 30 to control the reader 30 and read the identification number from the RF tag 2a of the RF tag part 2 attached to the material M through the reader 30 . At this time, the reading process may be performed while a plurality of materials M are packed in the package B. FIG. When acquiring the identification number, the mobile terminal 20 updates the materials management data D by associating the arrival information and the storage location information input through the display unit 24 with the identification number. Further, the mobile terminal 20 is configured to update the materials management data D by associating the identification number with the confirmation date indicating the date and time when the reading by the reader 30 was performed. As the confirmation date, for example, the current date and time on the system of the mobile terminal 20, the current date and time obtained from the network, or the like may be used.

Here, an example of updating the material management data D will be described. In the example of FIG. 13, the arrival date (September 21, 2017), the person in charge (Sato), and the storage location number (01) are input in advance to the mobile terminal 20 . 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 date of arrival (September 21, 2017) and the person in charge are assigned to the identification number "101". The materials management data D is updated so that the person (Sato), the confirmation date (September 21, 2017), and the storage location number (01) are associated (see FIG. 14).

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

Next, a method for inspecting the arrival of materials M in the arrival inspection system 300 will be described with reference to FIG. 15 . First, the operator operates the information processing device 10 to transmit the material management data D updated in step S25 to the portable terminal 20 (see step S31). The portable terminal 20 stores the materials management data D in the storage unit 23 .

Next, the worker inputs predetermined receipt information (eg, date of receipt, person in charge of receipt) and predetermined storage location information (eg, storage location 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. FIG. The mobile terminal 20 associates the information input to the mobile terminal 20 at the time of reading the identification number with the identification number, and updates the materials management data D (see step S33).

Next, the portable terminal 20 refers to the material management data D and determines whether or not there is an RF tag 2a that could not be read. When the mobile terminal 20 determines that there is no RF tag 2a that could not be read (NO in step S34), all the RF tags 2a have been read. (see step S36). The information processing device 10 stores the materials management data D in the storage unit 13 .

On the other hand, if the RF tags 2a are read while a plurality of materials M are packed in the package B, all the RF tags 2a may not be read. Therefore, when the portable terminal 20 determines that there is an RF tag 2a that could not be read (YES in step S34), the information about the RF tag 2a that could not be read is updated using the information of the RF tag 2a that has already been read. (see step S35).

The example of 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 receipt information and storage location information associated with the package number "091901" (for example, The confirmation date of the information (September 21, 2017), the location number (01), the person in charge of the location information (Sato), the date of confirmation of the location information (September 21, 2017)) are changed to the identification number "103".

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 identification number read by the portable terminal 20 through the reader 30 is associated with the information input by the worker, and the materials management data D is updated. . Therefore, the information input by the worker is recorded in the materials management data D at the timing when the portable 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, it becomes possible to perform the manufacturing work of the RF tag component 2 more efficiently.

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

(1) When the mobile terminal 20 reads the identification number stored in the EPC part A3 of the RF tag 2a through the reader 30 and the identification number is present in the materials management data D, the mobile 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, since the reading process is speeded up, it is possible to manage the materials M more efficiently.

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

(2) As shown in FIGS. 9, 13, 17, 21 and 25, the radio wave intensity for reading and writing the RF tag 2a may be changed by the operator through the display unit 24 ( see arrow E1). In this case, reading and writing of the RF tag 2a are performed with the magnitude of the radio wave intensity input by the operator. Therefore, the strength of radio waves 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 2a through the reader 30, the identification number in the materials 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. FIG. Therefore, the worker can 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 identification number is associated with the date and time of last reading, and the material management data D is updated. In the case of , the last read date and time may not be updated (see arrow E4). In FIG. 28, the state in which the last read date and time is locked is indicated by shading. In this case, even if the material management data D is tampered with, such as by manually updating the material information corresponding to the RF tag 2a, even though the RF tag 2a has not been read, The last reading date and time of material management data D is not updated. Therefore, by checking the date and time when the material management data D was last read by another worker, it is possible to easily discover falsification of the material management data D. FIG.

(5) For example, when searching for a predetermined material M using the portable terminal 20, a screen B6 as shown in FIG. may be presented to Further, 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. 29(b) on the display unit 24. As shown in FIG. 29(b), the screen B7 may include an input receiving section G. The input reception unit G may be, for example, a button-shaped GUI displaying "data update". When the operator operates the input reception unit G, a screen B8 as shown in FIG. 30 may be displayed on the display unit 24. FIG. The screen B8 is an update screen for updating various information corresponding to the material M found by the search. That is, when the operator operates the input reception unit G, the screen changes from the screen B7 to the screen B8. In this case, when the RF tag 2a of the material M being searched is read in the searching work of the material M by the mobile terminal 20, for example, the screen B7 showing the reading result and the input reception part G are displayed on the display part 24 as well. Therefore, by operating the input reception unit G, the worker can immediately transition to the screen B8 for updating the material management data D corresponding to the RF tag 2a. Therefore, it becomes possible to manage the materials M more efficiently.
