[0001] The present invention relates to an article management system and an article management method. More specifically, the present invention relates to an article management system and an article management method that can efficiently perform inspection management operations on various articles and contribute to improving the accuracy of management.

Background Art

[0002] In recent years, in the field of inspection management of articles, technologies such as the efficiency improvement of inventory management using RFID (radio frequency identification) tags, which read data wirelessly and identify and manage articles, have been widely used.

[0003] For example, a technique has been proposed that attempts to efficiently perform inspection management operations on articles having various inspection items using RFID tags (see Patent Document 1).

[0004] Here, in the article search system described in Patent Document 1, there are many types of target articles, and for the spare parts (articles) of an airliner having various inspection items, each article is attached with an RFID tag, and an article search is performed using an RFID tag search device.

[0005] Further, in the article search system described in Patent Document 1, a server having an external storage device storing spare part management information is configured to perform wireless communication with an RFID tag search device.

[0006] Further, the server distributes spare part management information such as the necessity of visual confirmation to the RFID tag search device, and when searching for an article that requires visual confirmation, the RFID tag search device relatively reduces the intensity of the reading radio wave for the RFID tag attached to the article, and guides the operator of the RFID tag search device to approach the article to a visually observable distance, and performs accurate guidance of the operator according to the necessity of visual confirmation or the like.

Patent Documents

[0007] [Patent Document 1] Japanese Patent Publication No. 2013-209184 [Overview of the project] [Problems that the invention aims to solve]

[0008] However, the following problems existed with the management of items using RFID tags, including the item search system described in Patent Document 1.

[0009] Firstly, there was a problem where, even if the RFID tag had been removed from the target item, the detection result would still indicate the existence of the item as long as the RFID tag was within reading range of the RFID tag search device.

[0010] In other words, for example, even if the item to be detected is not present on-site, if the RFID tag is attached to another item, shelf, or floor surface within the reading range, the RFID tag can still be read. As a result, accurate inventory status cannot be confirmed.

[0011] Furthermore, the item search system described in Patent Document 1 is configured to guide the operator of the RFID tag search device to approach items that require visual inspection to a distance where they can be visually inspected, making it possible to read the RFID tags without bringing them into contact with the RFID tag search device.

[0012] Furthermore, the RFID tag search device can read multiple RFID tags simultaneously and input inspection results and other information for multiple items all at once.

[0013] Therefore, workers can process items as if they had been inspected simply by reading multiple RFID tags and inputting the information, without actually having to pick up each item and perform a thorough inspection.

[0014] Therefore, regarding management systems for inspecting and managing goods, there is a need for the development of technologies that not only improve the efficiency of inspection work but also encourage thorough inspection of goods.

[0015] In particular, if the items subject to inspection and management belong to fields where safety and high construction quality are required, the need for technologies that can facilitate accurate inventory management and reliable inspection becomes even greater.

[0016] This invention was conceived in view of the above points, and aims to provide an item management system and item management method that enable efficient inspection and management of a wide variety of items and contribute to improving the accuracy of management. [Means for solving the problem]

[0017] To achieve the above objective, the present invention provides an article management system for managing a plurality of articles, comprising: a first tag for short-range wireless communication attached to the article and having unique first identification information; a second tag for wireless communication attached to the article and having unique second identification information different from the first identification information; a first reading means capable of reading one of the first tags by short-range wireless communication; a second reading means capable of reading a plurality of the second tags by wireless communication; a server device for recording article management information, which includes at least inspection result information and information on whether or not a repair request has been made for each of the plurality of articles; and a portable terminal device that can access the server device and input the article management information when the first tag is read by the first reading means or when the second tag is read by the second reading means.

[0018] Here, the first tag is attached to an item and has unique first identification information, making it possible to identify one item using the first identification information within a group of items that are to be subject to inspection and management. The unique first identification information referred to here is information assigned to each of the first tags, consisting of letters, numbers, or symbols, and means that multiple first identification information pieces are unique and do not overlap with each other.

[0019] Furthermore, because the second tag is attached to an item and possesses unique second identification information different from the first identification information, it becomes possible to identify a single item within a group of items that are to be inspected and managed using the second identification information as well. Also, since the same item is associated with two types of information—the first and the second identification information—it becomes possible to identify the target item more reliably. Moreover, even if either the first or second tag becomes unreadable due to damage or loss, the item can still be identified by checking the other tag attached to the item. In addition, it is easy to duplicate the damaged tag. The unique second identification information referred to here is information assigned to each second tag, consisting of letters, numbers, or symbols, and multiple second identification information entries are unique and do not overlap with each other. Furthermore, "different from the first identification information" means that the second identification information and the first identification information do not overlap, and this includes cases where the information does not overlap, for example, by having a different number of characters to make up the information.

[0020] Furthermore, since the first reading means can read one first tag via short-range wireless communication, the first tag can be read by bringing the first reading means into contact with the first tag attached to an item. In other words, by creating an action of bringing the first reading means into contact with each individual item, a situation is created in which the worker picks up the target item, encouraging the worker to thoroughly inspect the item.

[0021] In addition, the second reading means can read a plurality of second tags by wireless communication, enabling non-contact and batch reading of the plurality of second tags attached to an article. That is, for example, by arranging a plurality of articles to be inspected within the range where the tags can be read by the second reading means, the articles can be read collectively, making it possible to efficiently perform inspections and inventory checks.

[0022] In addition, by the server device recording article management information, which is information including at least inspection result information and information on the presence or absence of repair requests for each of the plurality of articles, it is possible to accumulate inspection result information and information on the presence or absence of repair requests for each individual article in a plurality of article groups targeted for inspection management in the server device. Also, an operator can confirm the article management information of an individual article by accessing the server device.

[0023] In addition, when the portable terminal device reads the first tag with the first reading means or reads the second tag with the second reading means, it can access the server device and input article management information. As a result, due to the operation of reading the tag by the first reading means or the second reading means, it becomes possible to add or modify new information to the article management information recorded in the server device. That is, in the case of reading the first tag, information such as inspection results for the corresponding single article can be input, and in the case of reading a plurality of second tags, information such as inspection results for the corresponding plurality of articles can be input.

[0024] In addition, when the first tag is an NFC tag, communication is possible within a communication distance of about 10 cm, and it can be read by contacting the first reading means. Also, it is possible to use a general-purpose device such as a smartphone terminal as the first reading means. For example, by adopting a smartphone terminal as the portable terminal device of the present invention, it becomes possible to make the portable terminal device also function as the first reading means.

[0025] Also, when the second tag is an RFID tag, communication is possible at a communication distance of several centimeters to several meters, and the second reading means can read the second tag non-contact. Also, since the unit price of the tag is relatively inexpensive, the introduction cost can be suppressed when applying to a large number of articles.

[0026] Also, when the second reading means has an article search function of detecting the second tag attached to a selected article by wireless communication when the mobile terminal device accesses the server and selects a specific article from the article management information, it is possible to easily search for a specific article whose location is unknown using the second reading means.

[0027] Also, when the first tag embedded in the personal card distributed for each user is provided, it is possible to identify the user's personal card with the first identification information.

[0028] Also, the article management information includes at least the inspection result information for articles without tags (tagless articles) that do not have the first and second tags. When the mobile terminal device reads the first tag of the personal card with the first reading means and can access the server device and input the article management information, the inspection result information for tagless articles can be recorded in the server device. That is, for example, it is possible to input the inspection information of cloth articles that cannot be tagged as tagless articles and manage such articles.

[0029] Furthermore, in order to achieve the above objectives, the present invention provides an article management method for managing multiple articles, comprising: a tag reading step of reading a first tag for short-range wireless communication attached to an article and having individual first identification information via short-range wireless communication, or reading a second tag for wireless communication attached to an article and having individual second identification information different from the first identification information via wireless communication; and an information management step of, based on the reading step, accessing a server device on a portable terminal device that records article management information, which includes at least inspection result information and information on whether or not a repair request has been made for each of the multiple articles, and inputting the article management information, wherein the tag reading step reads one of the first tags or reads multiple of the second tags, and the information management step is configured such that when the first tag is read, the article management information for the article to which the first tag is attached can be input, and when multiple of the second tags are read, the article management information for the multiple articles to which the read multiple second tags are attached can be input all at once.

[0030] In this process, by reading a first tag attached to an item, which has individual first identification information, it becomes possible to identify one item from a group of items that are to be subject to inspection and management using the first identification information.

[0031] Furthermore, in the tag reading process, by reading a second tag attached to an item that has a separate second identification information different from the first identification information, it becomes possible to identify a single item from a group of items that are to be inspected and managed using the second identification information. Also, since the same item has two types of information, the first and the second identification information, it becomes possible to identify the target item more reliably. Moreover, even if either the first or second tag becomes unreadable due to damage or loss, the item can still be identified by checking the other tag attached to the item. In addition, it is easy to duplicate the damaged tag.

[0032] Furthermore, in the tag reading process, by reading one first tag using short-range wireless communication, for example, by making the operator touch the reading device to each item one by one, it is possible to create a situation where the operator can pick up the target item and encourage the operator to thoroughly inspect the item.

[0033] Furthermore, in the tag reading process, by reading multiple second tags wirelessly, it becomes possible to read multiple second tags attached to an item simultaneously and without contact. In other words, for example, multiple items to be inspected can be placed within the range where the tags can be read, and the items can be read all at once, enabling efficient inspection and inventory checks.

[0034] Furthermore, in the information management process, based on the reading process, the mobile terminal device accesses a server device where item management information is recorded, which includes at least inspection result information and information on whether or not a repair request has been made for each of multiple items. By inputting this item management information, it becomes possible to add or modify new information to the item management information on the server device as a result of reading the tags. In other words, it is possible to input inspection result information and information on whether or not a repair request has been made for each individual item.

[0035] Furthermore, if the tag reading process reads multiple second tags, and the information management process inputs item management information for multiple items in a batch, and then the tag reading process reads the first tag of one of those items, and the information management process inputs item management information for the item with the first tag, then, based on the reading of the second tags, inspection information for multiple items can be input in a batch, and one of those items can be identified, and information on other inspection results for that identified item can be input, or if the item is broken, information on a repair request for that item can be input. As a result, it becomes possible to efficiently reflect multiple types of inspection results and repair requests in the item management information.

[0036] Furthermore, if the information management process includes an item retrieval process in which a mobile terminal device accesses a server to select a specific item from the item management information and a second tag attached to the selected item is detected via wireless communication, then it becomes possible to easily locate a specific item whose whereabouts are unknown by detecting the presence or absence of a specific second tag.

[0037] Furthermore, in the tag reading process, the first tag is read, and in the information management process, the item management information for the item with the first tag is entered. When the item search process is performed, based on the reading of the first tag, information such as the inspection results of the item is reflected in the item management information, and the item management information is checked to identify items for which the inspection results have not been entered, and the location of those items can be searched. In other words, individual inspection work can be performed while searching for items that have been missed during inspection, and the inspection of all items that need to be inspected can be carried out efficiently.

[0038] Furthermore, if the item management information includes information on whether or not inspection results meet predetermined conditions, and if the system includes an inspection defect detection process that detects items with information indicating no inspection results meeting predetermined conditions using the first or second tag of that item, then items for which the necessary inspection result information has not been entered can be identified as inspection defects and easily found by detecting the first or second tag. The specified conditions referred to here include, for example, whether or not information regarding specific inspection results has been entered within a certain period of time.

[0039] Furthermore, if the second tag is an RFID tag that has information about the direction of movement of the tag, and the system includes an inbound / outbound management process that detects information about the outbound or inbound of an item based on the information about the direction of movement of the tag when the item passes through a predetermined location, then it becomes possible to manage whether an item has been taken out of a specific location or taken back in based on the information about the direction of movement contained in the second tag. That is, for example, by designating the entrance of an office or warehouse as a predetermined location and acquiring and recording information about the movement of an item at that predetermined location, it becomes possible to grasp the status of items being out of or inbound from the office or warehouse. Also, for example, by combining this with the inspection defect detection process described above, it becomes possible to detect that an item has not undergone the necessary inspection when it is taken out, and to prevent its removal. [Effects of the Invention]

[0042] [Embodiments of the present invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings to facilitate understanding of the present invention. This section describes an item management system A, which is an example of an item management system to which the present invention is applied. Figure 1 is a diagram showing the overall schematic configuration of item management system A as an embodiment of the present invention. Note that the structure shown below is an example of the present invention, and the content of the present invention is not limited thereto.

[0043] [1. About the overall system configuration] As shown in Figure 1, an example of an item management system to which the present invention is applied, item management system A, comprises an equipment management server 1, a smartphone terminal 2, an RFID reader 3, and an external terminal 4.

[0044] This item management system A is a system for inspecting and managing a wide variety of equipment, tools, and other items that require periodic inspection and are used in power distribution construction work.

[0045] Here, the equipment management server 1 is a server that manages equipment management information 110, which is information about multiple pieces of equipment and tools that are to be managed (see Figure 1). Details of the equipment management information 110 will be described later.

[0046] Furthermore, the equipment management server 1 is configured to be accessible from smartphone terminals 2 or external terminals 4 via the internet 7, and is a server that sends and receives information with these terminals and provides various types of information in response to requests from these terminals.

[0047] Furthermore, smartphone terminal 2 is a terminal held by the worker performing the inspection work, and is used to transmit information such as the inspection results of equipment and tools to the equipment management server 1. Smartphone terminal 2 is also a terminal used to access the equipment management server 1 and check various information of the equipment management information 110 recorded on the equipment management server 1.

[0048] Furthermore, the RFID reader 3 is a device for reading the RFID tags 6 attached to the equipment and tools 100, which will be described later.

[0049] Furthermore, the RFID reader 3 is configured to communicate with the smartphone terminal 2 via Bluetooth® wireless communication.

[0050] For example, the RFID reader 3 sends the reading result information to the smartphone terminal 2, and the smartphone terminal 2 sends the same information to the equipment management server 1, thereby enabling the smartphone terminal 2 to access the equipment management server 1.

[0051] Furthermore, the external terminal 4 is a terminal for accessing the equipment management server 1 to check or modify various information in the equipment management information 110 recorded on the equipment management server 1. The external terminal 4 also functions as a management terminal for performing approval work to reflect the inspection results information of the equipment tools 100 entered by the worker into the recorded management information 110.

[0052] For example, a person in charge with management authority separate from the worker can use an external terminal 4 to approve information such as the inspection results of equipment and tools entered by individual workers.

[0053] As shown in Figure 1, for each piece of equipment or tool 100 managed by the item management system A, one NFC (Near Field Communication) tag 5 and one RFID tag 6 are attached.

[0054] Furthermore, the NFC tag 5 is an IC tag that has unique NFC identification information and is a component for identifying individual pieces of equipment 100 within the item management system A.

[0055] More specifically, one NFC tag 5 is assigned one NFC identification piece of information, and multiple NFC identification pieces of information do not overlap with each other. In other words, one piece of equipment or tool 100 is assigned one unique piece of information, and this NFC identification piece of information makes it possible to identify that piece of equipment or tool.

[0056] Furthermore, the NFC tag 5 is a tag that, when touched and read by the NFC reader 21 of the smartphone terminal 2 (described later), allows the smartphone terminal 2 to access the equipment management server 1.

[0057] Here, when the smartphone terminal 2 accesses the equipment management server 1, various information corresponding to the equipment tool 100 to which the NFC identification information of the read NFC tag is attached is made available on the smartphone terminal 2 from the equipment management information 110.

[0058] Furthermore, the RFID tag 6 is an IC tag having unique RFID identification information, and is a component for identifying individual pieces of equipment or tools 100 within the item management system A.

[0059] More specifically, each RFID tag 6 is assigned one RFID identification piece of information, and multiple RFID identification pieces of information do not overlap with each other. In other words, each piece of equipment or tool is assigned one unique piece of information, and that piece of equipment or tool can be identified not only by the NFC identification piece of information mentioned above, but also by the RFID identification piece of information.

[0060] In other words, each piece of equipment or tool (100 units) is identified by two types of unique information: corresponding NFC identification information and RFID identification information.

[0061] Furthermore, the NFC identification information and RFID identification information are composed of non-overlapping information. For example, both the NFC identification information and RFID identification information can be composed of a combination of numbers and letters, with a different total number of characters for each, or by fixing the initial letters to non-overlapping characters (for example, the NFC identification information may start with "1" and the RFID identification information with "2"). In this way, the NFC identification information and RFID identification information can be composed of non-overlapping information.

[0062] Furthermore, the RFID tag 6 allows the RFID reader 3 to read multiple RFID tags 6 within its readable range simultaneously and without contact.

[0063] Furthermore, when the RFID tag 6 is read, the reading result information is transmitted from the RFID reader 3 to the smartphone terminal 2, allowing the smartphone terminal 2 to access the equipment management server 1.

[0064] Here, when the smartphone terminal 2 accesses the equipment management server 1, the system is configured so that various information corresponding to the equipment tools 100 to which each RFID identification information is attached can be displayed on the smartphone terminal 2 for each of the RFID tags 6 that have been read from the equipment management information 110.

[0065] As shown in Figure 1, in the inventory management system A, each worker is given a personal card 101, and an NFC tag 50 is embedded in this personal card 101.

[0066] Furthermore, the NFC tag 50, like the NFC tag 5 described above, is an IC tag that has unique NFC identification information. In addition, there are untagged equipment and tools that do not have NFC tags 5, NFC tag 50, or RFID tag 6 attached, and multiple tools linked to an individual who possesses a personal card 101 are linked to the NFC tag 50.

[0067] Furthermore, untagged equipment and tools include items such as safety components lent to individual workers, and equipment and tools that are physically difficult to attach IC tags to, for reasons such as being made of cloth.

[0068] Furthermore, each NFC tag 50 is assigned a single piece of NFC identification information. Additionally, the NFC identification information of NFC tag 50 is unique and does not overlap with the NFC identification information of NFC tag 5.

[0069] Furthermore, the NFC tag 50 is a tag that, when touched and read by the NFC reader 21 of the smartphone terminal 2, allows the smartphone terminal 2 to access the equipment management server 1.

[0070] Here, when smartphone terminal 2 accesses equipment management server 1, various information corresponding to multiple untagged equipment tools linked to NFC tags 50 can be displayed on smartphone terminal 2 from the equipment management information 110.

[0071] Next, we will explain the details of each component.

[0072] [2. Equipment Management Server] As shown in Figure 1, the equipment management server 1 has an information recording unit 10 and an information transmission / reception unit 11.

[0073] Furthermore, the information recording unit 10 is the part that records equipment management information 110, which is information related to the management of equipment tools 100 and equipment tools that have not been tagged, which are subject to management by the item management system A.

[0074] The equipment management information 110 recorded in this information recording unit 10 can be viewed via the smartphone terminal 2 and the external terminal 4. Furthermore, the equipment management information 110 can be modified by inputting, correcting, and deleting its contents via the smartphone terminal 2 and the external terminal 4.

[0075] Furthermore, the information transmission / reception unit 11 is the part that transmits and receives information between the smartphone terminal 2 and the external terminal 4. This information transmission / reception unit 11 is configured to receive request information from the smartphone terminal 2 and transmit various information corresponding to the request to the smartphone terminal 2.

[0076] [3. Equipment Management Information] As shown in Figure 2, the equipment management information 110 recorded in the information recording unit 10 includes various types of information as described below.

[0077] This various information includes, for the equipment and tools 100, category information 111, classification information 112, product name information 113, manufacturer information 114, specifications / model information 115, standards information 116, unit information 117, manufacturing date information 118, serial number information 119, start of use date information 120, NFC identification information 121, RFID identification information 122, inspection item information 123, inspection cycle information 124, inspection date information 125, inspection type information 126, inspection result information 127, ownership information 128, inspector information 129, and repair request information 130.

[0078] Here, category information 111 is information indicating the general type of equipment or tool 100; for example, if the item is a personal computer, the information "personal computer" is recorded. Classification information 112 is information indicating the type of equipment or tool 100 determined according to the content of the category; for example, if the item is a personal computer, the information "main unit" is recorded.

[0079] Furthermore, item name information 113 is information about the name of the equipment / tool ​​100; for example, if the item is a personal computer, the information "Desktop PC" will be recorded. Manufacturer information 114 is information about the manufacturer (company name) that produced the equipment / tool ​​100. Specifications / model information 115 is information about the specifications / model of the equipment / tool ​​100.

[0080] Furthermore, standard information 116 refers to information about the specifications (information representing dimensions, shape, quality, etc.) of the equipment and tools 100. In addition, unit information 117 refers to information about the units of the equipment and tools 100; for example, if the item is a personal computer, the notation "unit" will be recorded.

[0081] Furthermore, the manufacturing date information 118 is the year and month in which the equipment / tool ​​100 was manufactured. The serial number information 119 is the serial number assigned by the manufacturer or other party to identify the equipment / tool ​​100. Finally, the start of use date information 120 is the year and month in which the worker began using the equipment / tool ​​100.

[0082] Furthermore, the NFC identification information 121 is unique NFC identification information possessed by the NFC tag 5 attached to the equipment tool 100, and is information used in the item management system A to identify the equipment tool 100.

[0083] Furthermore, the RFID identification information 122 is the unique RFID identification information of the RFID tag 6 attached to the equipment tool 100, and is used in the item management system A to identify the equipment tool 100.

[0084] Furthermore, inspection item information 123 refers to information about the inspection content set for each type of equipment or tool 100. The content of this inspection item information 123 differs depending on the type of equipment or tool 100. Also, as will be described later, inspection item information 123 includes information classified as "daily inspection items" and information classified as "calibration test items".

[0085] Furthermore, inspection cycle information 124 is information about the frequency at which inspection work is performed, which is set for each type of equipment tool 100, and information such as "daily" or "once a month" is recorded. Inspection date information 125 is information about the date on which the worker performed the inspection work on the equipment tool 100.

[0086] Furthermore, the inspection type information 126 refers to the equipment and tools 100 used in the inspection work, as described below. This information indicates whether the item is subject to inspection under the "daily inspection items" or under the "calibration test items."

[0087] Furthermore, the inspection result information 127 is information about the results of the most recent inspection work performed on the equipment and tools 100, such as "○ (completed and good)", "× (completed and poor)", or "not inspected" determined based on the inspection cycle information 124.

[0088] Furthermore, ownership information 128 is information regarding the ownership of the equipment / tool ​​100. For example, if the item is owned by a team, the name of the team is recorded, and if the item is owned by an individual, the owner's name is recorded. Inspector information 129 is information regarding the name of the person who performed the most recent inspection on the equipment / tool ​​100.

[0089] Furthermore, the repair request information 130 is information that records when a worker requests repairs for equipment or tools 100 that require repair as a result of inspections such as those described in the "daily inspection items" below. This repair request information 130 includes the applicant's name, the date the repair request was submitted, and information about the nature of the malfunction.

[0090] Furthermore, the equipment management information 110 recorded in the information recording unit 4 includes not only information about the equipment and tools 100, but also information similar to the various types of information mentioned above regarding equipment and tools that have not been tagged.

[0091] Regarding the various information concerning equipment and tools that have not been tagged, the NFC identification information 121 refers to the NFC identification information assigned to the NFC tag 50 embedded in the personal card 101. Furthermore, the RFID identification information 122 mentioned above is not included in the various information concerning equipment and tools that have not been tagged.

[0092] Here, the types of information included in the equipment management information 110 regarding the equipment and tools 100 are limited to those described above, as long as they can identify the items to be managed using two types of information: NFC identification information and RFID identification information, enabling individual management, and include information on inspection results and repair requests. Furthermore, the content of the equipment management information 110 can be appropriately set according to the type of items to be managed.

[0093] Furthermore, it is not necessarily required that the equipment management information 110 include various information regarding equipment and tools that have not been tagged. However, since it is possible to centrally manage multiple pieces of equipment and tools that have not been tagged, together with the equipment and tools 100, by linking items that are difficult to tag with IC tags to a single personal card 101, it is preferable that the equipment management information 110 include various information regarding equipment and tools that have not been tagged.

[0094] Next, we will explain the inspection of the "daily inspection items" and the "calibration test items" related to the inspection type information 126 mentioned above.

[0095] The equipment and tools 100 managed by the item management system A of the present invention include multiple types of tools and items, and these tools and items include tools that are subject to inspection under "daily inspection items", tools that are subject to inspection under "calibration test items", and tools that are subject to inspection under both "daily inspection items" and "calibration test items".

[0096] Here, the "daily inspection items" refer to inspections that workers perform on a daily basis on 100 pieces of equipment and tools related to power distribution work. This involves performing a simple visual inspection of each item and reporting the inspection results.

[0097] In the item management system A of the present invention, the inspection of "daily inspection items" is performed by an employee touching the NFC tag 5 of the target equipment tool 100 with a smartphone terminal 2 to read the NFC tag 5, picking up the target item, performing the necessary inspection items, and reflecting the inspection results on the smartphone terminal 2 into the equipment management information 110 of the equipment management server 1.

[0098] Furthermore, the equipment and tools 100 subject to inspection under the "daily inspection items" include, for example, indirect tools (strain rods, indirect tensioners, etc.), mechanical tools (hydraulic compression heads, rechargeable hydraulic compression tools, etc.), or safety equipment (safety helmets, voltage detectors, full harnesses, etc.).

[0099] Furthermore, the "calibration test items" inspection involves conducting periodic voltage withstand and X-ray tests, etc., on 100 pieces of equipment and tools related to power distribution work, not by workers, with the aim of ensuring worker safety and construction quality. This inspection detects defects that cannot be found through daily inspections and also inspects measuring instruments, etc. This inspection ensures proper construction quality and prevents disasters and power outage accidents during work.

[0100] More specifically, the process involves insulation performance testing using voltage withstand testing equipment, diagnosis of metal fatigue and other issues using X-ray non-destructive testing equipment, cable degradation diagnosis using high-voltage insulation resistance meters, and inspection of equipment using standard instruments.

[0101] In the item management system A of the present invention, the inspection of "calibration test items" is performed, for example, by gathering multiple pieces of equipment and tools 100 of the same type that are subject to inspection and owned by a business establishment, etc., in one place, and having an expert inspect the necessary inspection items.

[0102] Furthermore, the worker uses the RFID reader 3 to read the RFID tags 6 of multiple target pieces of equipment and tools 100 in a contactless manner, and then uses the smartphone terminal 2 to reflect the inspection results information performed by the expert into the equipment management information 110 on the equipment management server 1.

[0103] Furthermore, the equipment and tools 100 subject to inspection under the "calibration test items" include, for example, indirect tools (strain rods, indirect tensioners, etc.) and uninterruptible power supply equipment (high-voltage construction cables, connecting tubes, temporary support concrete, etc.).

[0104] As mentioned above, depending on the type of equipment or tool (100), some tools, like the indirect tools described above, are subject to both "daily inspection items" and "calibration test items."

[0105] Furthermore, untagged equipment and tools are subject to inspection according to the "daily inspection items." Safety equipment (safety helmets, full harnesses, etc.) provided to individual workers is inspected by the workers themselves according to the "daily inspection items."

[0106] In this process, the worker touches the NFC tag 50 on their personal card 101 to read the NFC tag 50, picks up the item in question, inspects it according to the required inspection items, and then uses the smartphone terminal 2 to reflect the inspection results in the equipment management information 110 on the equipment management server 1.

[0107] Here, the contents of the "daily inspection items" described above are just examples of inspections performed after touching and reading the NFC tag 5, and the contents of the present invention are not limited to these, and the contents of the inspection can be set as appropriate.

[0108] Furthermore, the content of the "calibration test items" described above is merely an example of an inspection performed after reading multiple RFID tags 6 simultaneously and without contact. The present invention is not limited to this, and the content of the inspection can be set as appropriate.

[0109] [4. Smartphone devices] As shown in Figure 1, the smartphone terminal 2 is equipped with a processing unit 20. The processing unit 20 is a processing unit that executes each of the information processing functions of the smartphone terminal 2.

[0110] In other words, in the item management system A, the processing unit 20 of the smartphone terminal 2 functions as an NFC reader 21, an information input unit 22, an information transmission / reception unit 23, etc. Through the processing functions of each of these units, reading of NFC tags 5 (or NFC tags 50), transmission and reception of information, notification of various types of information, creation and display of display information, etc. The smartphone terminal 2 also has a display screen 24.

[0111] Here, the smartphone terminal 2 has known application software implemented that provides wireless communication functionality using NFC tags, and the processing unit 20 is able to read the NFC tag 5 as an NFC reader 21 through the functions of this application software.

[0112] Furthermore, the information input unit 22 is the part that inputs information via operation buttons, etc., displayed on the display screen 24. For example, when a smartphone terminal 2 accesses the equipment management server 1, it can perform operations such as inputting or selecting information via the information input unit 22 on the display screen 24 where each piece of equipment management information 110 is displayed.

[0113] Furthermore, the information transmission / reception unit 23 is responsible for transmitting and receiving information between the smartphone terminal 2 and the equipment management server 1 or the RFID reader 3.

[0114] [5. RFID Reader] As shown in Figure 1, the RFID reader 3 includes an information transmission / reception unit 30, a tag antenna 31, and a trigger switch 32.

[0115] Furthermore, the information transmission / reception 30 is responsible for transmitting and receiving information between the smartphone terminal 2 and the RFID reader 3, and communicates using Bluetooth® wireless communication.

[0116] Furthermore, the tag antenna 31 is responsible for communicating with the RFID tag 6 and reading the RFID tag 6. The trigger switch 32 is an operation unit operated by the operator to enable the reading of RFID tags 6 that are within the reading range of the tag antenna 31.

[0117] In addition, the RFID reader 3 has the function of reading multiple RFID tags 6 within its readable range all at once, and also the function of searching for the RFID tags 6 of a specified piece of equipment or tool 100 by accessing the equipment management server 1 with a smartphone terminal 2 and specifying that piece of equipment or tool 100.

[0118] In other words, the RFID reader 3 can identify the RFID identification information of the RFID tag 6 of equipment or tool 100 whose location is unknown from the equipment management information 110, and then find the RFID tag 6 that has that RFID identification information by contactless reading.

[0119] Next, we will explain the inspection and management of multiple pieces of equipment and tools 100 using the item management system A to which the present invention is applied, using specific examples.

[0120] [Using NFC tags] (Inspection of daily inspection items) First, in the inventory management system A, workers can perform daily inspection tasks for individual pieces of equipment and tools 100.

[0121] In this routine inspection, the worker touches the NFC tag 5 of the equipment / tool ​​100 to be inspected with a smartphone terminal 2 to read the NFC tag 5, then picks up the equipment / tool ​​100 and visually inspects each inspection item. After that, the inspection results can be entered and reflected in the equipment management information 110 (see Figure 3).

[0122] Here, for example, dedicated application software related to various functions of the inventory management system A is installed on the smartphone terminal 2. By launching this application software and operating the information input unit 22, it is possible to read the NFC tag 5 and input information on the results of inspection work.

[0123] Furthermore, Figure 4 shows an example of a screen on display screen 24 related to the inspection of daily inspection items.

[0124] The worker launches the application software on the smartphone terminal 2 and, for example, selects "Daily Inspection Registration." The daily inspection registration page 240 shown in Figure 4(a) is then displayed on the screen 24. By pressing the "NFC Management Equipment" tab on this screen, the NFC reader 21 is activated, making it ready to read the NFC tag 5.

[0125] Then, from that state, the smartphone terminal 2 (NFC reader 21) is brought into contact with the NFC tag 5 of the equipment tool 100 to be inspected, and the NFC tag 5 is read.

[0126] Furthermore, by reading the NFC tag 5, the smartphone terminal 2 becomes able to access the equipment management server 1, and page 241 of the inspection management sheet for the target equipment tool 100 from the equipment management information 110 recorded in the information recording unit 10 of the equipment management server 1 is displayed on the display screen 24 (see Figure 4(b)).

[0127] Furthermore, page 241 of the inspection management sheet shown in Figure 4(b) displays product name information 113 and inspection item information 123 related to the equipment and tools 100 in question.

[0128] The worker visually inspects the equipment and tools 100 for each inspection item of the inspection item information 123 displayed on the display screen 24, and inputs the inspection results on the same screen.

[0129] Furthermore, once the worker has entered the inspection results for all inspection items on the screen and selected the "Save" tab on page 241 of the inspection management sheet, the display screen 24 will transition to the next inspection result registration page 242 (see Figure 4(c)).

[0130] On this inspection results registration page 242, selecting the "OK" tab sends information about the inspection results of the daily inspection items performed by the worker to the equipment management server 1.

[0131] Furthermore, the inspection results information obtained by the worker is initially recorded on the equipment management server 1 in a "pending approval" state. Then, a person in charge with management authority other than the worker can use an external terminal 4 to check the contents of the pending approval information and approve it, at which point the inspection results information will be officially reflected in the equipment management information 110.

[0132] In this routine inspection, the worker needs to read the NFC tag 5 by making contact with each piece of equipment 100, which creates a situation where the worker is holding the equipment 100, thus encouraging the worker to perform the routine inspection of the equipment items visually.

[0133] This prevents the inclusion of unfair inspection results, such as when an operator inputs inspection results without visually inspecting the equipment or tools 100 in question, thereby ensuring proper management of the equipment and tools 100.

[0134] (Repair request) Furthermore, if, during the inspection of the daily inspection items, the equipment or tools 100 in question are found to be malfunctioning or damaged, the worker can request repair of the items using the inventory management system A.

[0135] In this repair request, the worker can touch the NFC tag 5 of the equipment tool 100 to be repaired with their smartphone terminal 2 to read the NFC tag 5, access the equipment management server 1, and send the repair request information to the equipment management server 1 (see Figure 5).

[0136] Furthermore, information about repair requests made by workers is initially recorded on the equipment management server 1 in a "pending approval" state. Then, a person in charge with management authority other than the worker can use an external terminal 4 to review and approve the contents, at which point the information about the repair request is officially reflected in the equipment management information 110.

[0137] Furthermore, the inspection and repair requests for the daily inspection items mentioned above can be carried out in the same manner not only for equipment and tools 100 with NFC tags 5 attached, but also for equipment and tools without tags that are linked to the NFC tags 50 on the personal cards 101 owned by the workers.

[0138] When dealing with equipment and tools that have not been tagged, the NFC tag 50 embedded in the personal card 101 is read by touching the smartphone terminal 2 to the personal card 101, allowing access to the equipment management server 1. This enables the smartphone terminal 2 to input inspection results and request repairs for the untagned equipment and tools linked to the NFC tag 50.

[0139] In this way, even equipment and tools without tags, such as items personally lent to workers or items to which IC tags cannot be attached, can be properly inspected and managed using the item management system A.

[0140] [Use of RFID tags] Furthermore, the inventory management system A allows for the simultaneous inspection of calibration test items for multiple pieces of equipment and tools 100.

[0141] In the inspection of these calibration test items, multiple pieces of equipment and tools 100 of the same type, which are the equipment and tools to be inspected, are gathered in one place, and an expert inspects the necessary inspection items for that type of equipment and tools.

[0142] Furthermore, as an example of how to proceed with the inspection, one possible approach is to perform the first inspection on multiple pieces of equipment / tools 100 of the same type, input the results of that inspection together, and then subsequently perform the second inspection on the same pieces of equipment / tools 100, inputting the results of that inspection together.

[0143] Furthermore, after the inspection results for each item are obtained, the worker can use the RFID reader 3 to contactlessly read the RFID tags 6 of multiple pieces of equipment 100 at once, input the inspection results for all the pieces of equipment 100 at once using the smartphone terminal 2, and reflect them in the equipment management information 110 (see Figure 6).

[0144] Here, when the RFID reader 3 reads multiple RFID tags 6, the reading results are transmitted from the RFID reader 3 to the smartphone terminal 2. The dedicated application software mentioned above is then launched on the smartphone terminal 2, and the information input unit 22 is operated to input the results of the inspection work.

[0145] Furthermore, by receiving information on the reading results of multiple RFID tags 6, the smartphone terminal 2 becomes able to access the equipment management server 1, and the input screen (not shown) of the inspection results for the calibration test items of the target equipment tools 100, which are recorded in the equipment management information 110 of the equipment management server 1, is displayed on the display screen 24.

[0146] The worker inputs the inspection results for multiple pieces of equipment 100 at once, for the first item among the calibration test items displayed on the display screen 24, specifically for the relevant calibration test item.

[0147] Furthermore, when an operator inputs inspection results for multiple pieces of equipment 100 at once and selects the "Save" tab on the inspection results input screen, the display screen 24 transitions to the next inspection results registration page (not shown).

[0148] When the "OK" tab is selected on this inspection results registration page, the inspection results for the first item of each of the selected pieces of equipment 100 are sent to the equipment management server 1.

[0149] Furthermore, during the calibration test item check, for the second and subsequent items, after the expert's inspection results are obtained, the RFID tag 6 is read and the inspection results are entered repeatedly in the same manner as described above.

[0150] Furthermore, the inspection results information for the entered calibration test items is initially recorded on the equipment management server 1 in a pending approval state. Then, a person in charge with management authority separate from the operator can use an external terminal 4 to review and approve the contents, at which point the inspection results information is formally reflected in the equipment management information 110.

[0151] In this calibration test item inspection, the inspection results information performed by experts is read collectively by an RFID reader 3 for multiple target pieces of equipment 100, and then entered collectively as equipment management information 110 on a smartphone terminal 2, making it possible to efficiently input inspection result information.

[0152] (Tool search) Next, we will describe the function of locating unknown equipment and tools 100 via RFID tags 6.

[0153] Here, the RFID reader 3 can detect a specific RFID tag 6 by identifying the RFID identification information and then reading the RFID tag 6 contactlessly. In other words, if the location of equipment or tool 100 is unknown, the equipment or tool 100 can be located by detecting the RFID tag 6 of that equipment or tool (see Figure 7).

[0154] In this process, the worker first accesses the equipment management server 1 using their smartphone terminal 2, selects the search menu using the dedicated application software mentioned above, and determines the specific piece of equipment 100 they wish to find. In other words, they identify the RFID identification information of the piece of equipment 100 to be searched.

[0155] Then, the smartphone terminal 2 transmits information about the RFID tag 6 attached to the selected equipment tool 100 to the RFID reader 3. The RFID reader 3 enters a state where it reads only the specific RFID tag 6 it has received, and by moving with the RFID reader 3, the worker can detect and locate the RFID tag 6.

[0156] Furthermore, the detection mechanism is configured such that when a specific RFID tag 6 is located within the readable range of the RFID reader 3, the RFID reader 3 sounds an alarm. The alarm also increases in volume as the distance between the RFID tag 6 and the RFID reader 3 decreases.

[0157] Here, since the communication range between the RFID reader 3 and the RFID tag 6 is in the range of a few centimeters to a few meters (up to about 7 meters), when searching for equipment and tools 100, setting the communication range of the RFID reader 3 to a longer range makes it possible to find the equipment and tools 100 whose whereabouts are unknown more efficiently.

[0158] Furthermore, while the above example shows a search process starting from a point where the missing equipment / tool ​​100 has been identified, the inventory management system A can also perform the task of identifying the missing equipment / tool ​​100.

[0159] For example, let's consider a case where you own 10 identical pieces of equipment or tools (100 each), but the whereabouts of one of them are unknown.

[0160] In this process, the equipment management information 110 is set to read the RFID tags 6 of the 10 pieces of equipment / tools 100, and the tags are read in the warehouse or elsewhere.

[0161] If, as a result of this reading, the RFID tags 6 of nine pieces of equipment 100 are read, but the remaining RFID tag 6 is not read, the RFID identification information (RFID tag 6) of that remaining piece of equipment 100 can be identified by comparing the reading results with the equipment management information 110.

[0162] In other words, the target of the equipment / tool ​​100 whose whereabouts are unknown becomes clear, and by making this one item the target of detection, the equipment / tool ​​100 can be found by searching with the RFID reader 3.

[0163] (Anti-theft function) Next, we will explain the function of preventing the removal of equipment and tools 100 that have been improperly inspected, using RFID tags 6.

[0164] In this case, when reading the RFID tag 6 with the RFID reader 3, the directionality of the RFID reader 3 can be used to detect information about the direction of movement of the RFID tag 6.

[0165] In other words, by installing an RFID reader 3 at a designated gate or the like, and detecting the direction of movement of the RFID tag 6 as it passes through the gate, it is possible to confirm whether the RFID tag 6 has been released from or received within the area of ​​a business premises or the like.

[0166] Furthermore, the equipment management information 110 recorded in the equipment management server 1 includes, as mentioned above, inspection cycle information 124, inspection date information 125, inspection result information 128, etc. In other words, it includes information indicating whether or not the necessary inspection work has been performed for each piece of equipment or tool 100, and it is possible to determine from the information in the equipment management information 110 whether or not the equipment or tool has been inadequately inspected.

[0167] Therefore, for example, when equipment and tools 100 are taken out for use outside the premises of a business or other facility, the departure of the equipment and tools 100 can be detected at a designated gate, and if the equipment and tools 100 are found to be inadequately inspected, the system can detect this, sound an alarm, and notify the user of the situation (see Figure 8).

[0168] Furthermore, by recording the outbound or inbound information of the RFID tag 6 when passing through a designated gate, it becomes possible to ascertain the usage history of the equipment and tools 100, as well as whether they are present in the warehouse, etc., from the equipment management information 110.

[0169] [Use of NFC tags and RFID tags] Next, we will explain a use case in which NFC tags 5 and RFID tags 6 are used together in the item management system A.

[0170] (Inspection of calibration test items and repair request) The first use case is the simultaneous inspection of calibration test items and the request for repair of equipment and tools 100, as described above (see Figure 9).

[0171] Here, the calibration test items are checked, and the RFID tags 6 of multiple pieces of equipment 100 are read contactlessly and simultaneously using the RFID reader 3. When the inspection results for the multiple pieces of equipment 100 are entered simultaneously using the smartphone terminal 2, it is assumed that there is a tool among the inspected pieces of equipment 100 that requires repair.

[0172] On smartphone terminal 2, for the equipment and tools 100 to be repaired, the results of the calibration test items are entered as "defective" or similar.

[0173] At the same time, the NFC reader 21 of the smartphone terminal 2 is activated, and the NFC tag 5 of the equipment tool 100 to be repaired is brought into contact with it to read the NFC tag 5, access the equipment management server 1, and send the repair request information to the equipment management server 1.

[0174] In this way, by simultaneously checking the calibration test items and requesting repairs for the equipment and tools 100, it becomes possible to efficiently reflect the repair request in the equipment management information 110 when the equipment and tools 100 that are subject to repair are identified during the calibration test item check.

[0175] Furthermore, since the process involves touching the smartphone terminal 2 to the NFC tag 5 for reading, it prevents the misidentification of other equipment and tools 100 that are not subject to repair requests, allowing for accurate repair requests for the equipment and tools 100.

[0176] (Checking daily inspection items and searching for tools) The second use case is a combination of the inspection of the daily inspection items mentioned above and tool retrieval (see Figure 10).

[0177] Here, for each piece of equipment or tool 100 that is subject to daily inspection, the smartphone terminal 2 is touched to the NFC tag 5 of each piece of equipment or tool 100 to read the NFC tag 5, the equipment or tool 100 is picked up and visually inspected to check each inspection item, and the inspection results are entered.

[0178] Furthermore, at that time, information listing the equipment and tools 100 owned by the business establishment is displayed on the display screen 24, and equipment and tools 100 for which inspection results are not displayed can be identified from the list of inspection result information 128. In other words, equipment and tools 100 that have been missed during inspection can be identified.

[0179] If there are any equipment or tools 100 that have been missed during inspection, the user selects a search menu to identify the missing equipment or tool 100. The smartphone terminal 2 then transmits information about the RFID tag 6 attached to the identified equipment or tool 100 to the RFID reader 3. The RFID reader 3 then enters a state where it reads only the specific RFID tag 6 it receives. By moving the RFID reader 3 with the user, the RFID reader 3 can detect the RFID tag 6 and locate the missing equipment or tool 100.

[0180] In this way, by combining the inspection of daily inspection items with tool searching, it is possible to quickly identify equipment and tools 100 that have been missed during inspection while simultaneously performing the inspection of daily inspection items, and to reliably carry out the inspection of the daily inspection items for the target equipment and tools 100.

[0181] (Checking calibration test items and checking daily inspection items) The third use case is one in which the calibration test items and the daily inspection items are checked together, as described above (see Figure 11).

[0182] Here, calibration test items are checked, and the RFID tags 6 of multiple target pieces of equipment 100 are read contactlessly and simultaneously using the RFID reader 3. The inspection results for the multiple pieces of equipment 100 are then entered into the smartphone terminal 2.

[0183] Furthermore, for the calibration test items, the smartphone terminal 2 is brought into contact with the NFC tag 5 of each piece of equipment 100 that has been gathered in one place to read the NFC tag 5. The equipment 100 is then picked up and visually inspected to check each inspection item, and the inspection results are entered.

[0184] In this way, by combining the inspection of calibration test items with the inspection of daily inspection items, two types of inspections can be carried out efficiently.

[0185] Furthermore, regarding the equipment and tools 100 that are subject to inspection of calibration test items, compared to the method of performing only routine inspection items separately, the effort of searching for the equipment and tools 100 each time is eliminated, and in this respect as well, the efficiency of the inspection work can be improved.

[0186] (Recovery in case of IC tag damage) The fourth use case involves using a single piece of equipment 100 to restore an IC tag if either the NFC tag 5 or the RFID tag 6 is damaged (see Figure 12).

[0187] Here, we will consider an example where the NFC tag 5 is damaged in one piece of equipment 100. In this piece of equipment 100, the NFC tag 5 is damaged and cannot be read by the NFC reader 21.

[0188] Here, since the equipment tool 100 has an RFID tag 6 attached to it, the equipment tool 100 can be identified from the equipment management information 110 by reading the RFID tag 6 with the RFID reader 3.

[0189] Furthermore, since the equipment management information 110 also includes the NFC identification information 121 of the NFC tag 5 of the equipment tool 100, it is possible to easily duplicate the damaged NFC tag 5a by checking the NFC identification information 121. Also, by replacing the damaged NFC tag 5 with a new NFC tag 5a, it becomes possible to manage the equipment tool 100 using both the NFC tag 5a and the RFID tag 6.

[0190] As described above, in item management system A, which is an example of an item management system to which the present invention is applied, reliable identification of various items such as equipment and tools used in power distribution construction is possible by using two types of IC tags, NFC tag 5 and RFID tag 6.

[0191] Furthermore, by reading the RFID tags 6 of multiple pieces of equipment 100 at once with the RFID reader 3 and inputting the inspection results for calibration test items, it becomes possible to perform inspections efficiently.

[0192] Furthermore, by reading the NFC tag 5 with a smartphone terminal 2 (NFC reader 21) in contact with each piece of equipment 100, workers are encouraged to perform the daily inspection tasks that are usually done visually. This prevents failure to perform inspections or inputting inspection results without visually inspecting the equipment 100, thus preventing the reflection of improper inspection results and ensuring proper management of the equipment 100.

[0193] As described above, the article management system of the present invention enables efficient inspection and management of a wide variety of articles, and contributes to improving the accuracy of management. Furthermore, the article management method of the present invention allows for efficient inspection and management of a wide variety of articles, and contributes to improving the accuracy of management.
