Description

The present invention relates to an information grasp management device that determines a state of an object by information processing of an electronic storage device having a communication function attached to the object.

Conventionally, an electronic storage device that has a data storage area for storing a unique management code and other data and has a wireless communication unit for reading and writing data in a contact type or a non-contact type using a radio wave is used. Thus, techniques for grasping and managing the state of things have been proposed.

For example, in Patent Document 1 below, a means for transporting articles (such as a trolley) is provided with a wireless communication type display means capable of rewriting display contents, and a wireless communication type RFID tag having a unique tag ID. When a change occurs in the articles loaded on the transporting means, the loaded article information displayed on the display means and data of the articles registered in the database in association with the tag ID are updated. Invention is described.

According to the invention of Patent Literature 1, it is possible to arbitrarily set or update data associated with each truck, and it is also possible to collate and visually check the articles loaded on the truck. It is said that it is possible to respond in real time at the time and to prevent identification errors of a cart carrying goods.

Further, in Patent Literature 2 below, a storage element capable of writing and reading tire production data in a non-contact manner is attached to a tire constituent member or a transport vehicle on which the tire is mounted, and stored in the storage element. The invention describes that position data of the transport vehicle is managed by reading vehicle ID data by position detection means installed in a tire conveyance path.

As represented by the inventions described in Patent Literature 1 and Patent Literature 2, the management information of an object has a unique management code that is closed in one company or related companies, thereby enabling the companies or related companies to share information. Information is shared.

However, when other companies are in charge of transporting goods, such as logistics, management and tracking are performed using the management code of the transportation company, and the management code of the transportation company and the management code within the company that requested the transportation are Is often not a one-to-one correspondence. In that case, the management data of both companies must be matched to find out which management code of the company that requested the transportation corresponds to, is included in, or corresponds to a plurality of management codes of the transportation company.

At this time, the management systems of both companies need to exchange information in real time with each other, and it is difficult to realize such interconnection between companies due to the sharing of investment. For this reason, management of things that have left the company cannot be performed with quick information tracking, and for example, it is not possible to quickly find out where and how many product stocks, including in physical distribution.

Further, in one factory, the storage location of items taken out of the warehouse depends on people. For example, in the invention described in Patent Literature 1, article information is managed for each truck on which the article is loaded, and it is not possible to grasp the state of the article that has been taken out of the cart and processed or assembled. For example, where the product is now or when the production volume changes over time, the number of stocks cannot be obtained in real time, and it depends on manual physical confirmation.

In the manufacturing industry, in which processing is often shared among companies, the management method during material processing and processing differs for each company, and the management code used for the management also differs. For this reason, the progress of the processing state of one product cannot be monitored throughout the related companies.

Furthermore, it is impossible for a person who is looking at something to know whether something is correct or abnormal.
For example, in the invention disclosed in Patent Document 2, by detecting a reading position of an RFID tag attached to a tire, it is possible to grasp in which process the target tire is located or whether the target tire is present in stock in a stock storage location. However, it is not possible to judge whether a product is defective or stockpiled unless a notice such as a sticker is posted on the item, and it takes time to confirm or make an inquiry.

As described above, it is considered that the location of the object, the content of the object, and the reason for the existence thereof change with time. In addition, transporting and processing of objects are performed by humans, and even a robot requires the existence of the robot.

That is, in order for the existence position of an object to change with time, it is necessary that a person or a machine be present and be in an operable state. These conditions are in place, there is a thing, and a set of information combining information selected for the purpose, such as instructions to transport or process the thing (hereinafter referred to as a combination information set) It can be transported and processed, and the location of the object is changed.

In this way, the existence position of a thing is determined by the purpose of existence and its existence condition, but since these information sets are information that each company or each person manages a partial part, the object is viewed. With just doing it before, it is impossible to know the information set of these things, and lack of quick decision-making in people's lives and business operations.

As described above, a closed company (a system in which the management code stored in the electronic tag is guaranteed to be unique) in one company or related companies is an open system (electronic tag). In the process of moving a system in which the stored management code is not guaranteed to be unique), there is a need for a method that can obtain necessary information from the object, and a communication function attached to the object An information comprehension and management device for discriminating a state of an object by information processing of an electronic storage device having the above is devised.

FIG. 2 is a diagram showing a process of processing and transporting the part a in the company A, and FIG. 3 is a diagram in which the reading is performed by the reader / writer possessed by the worker a or the transporter a in the processing and transporting process shown in FIG. FIG. 2 is a diagram showing electronic tags to be used and their times.

In the process 50 of FIG. 2, the part a is processed by the worker a using the equipment a in the processing place a. In the process 51 of FIG. 2, the processed part a is loaded on the carrier a by the carrier a and Transported from a to shipping area a.

At time t (1), the carrier a transports the unprocessed part a to the processing site a, and the electronic tag a3 locked to the component a, and the information collection post 1 installed at the processing site a locks the electronic tag a3. The electronic tag a4 and the electronic tag a2 locked to the ID card of the carrier a are simultaneously read using the reader / writer 2.

Subsequently, at time t (2), the worker a completes the preparation for processing the equipment a, and the electronic tag a3 locked to the part a, the electronic tag a8 locked to the equipment a, and the ID card of the worker a. The electronic tag a1 locked by the reader is simultaneously read using the reader / writer 1.

Subsequently, at time t (3), the worker a has the electronic tag a3 locked on the part a at the time of starting the processing of the part a, the electronic tag a6 locked on the card on which “processing started” is described, and the worker a. The electronic tag a1 locked to the ID card of the user a is read simultaneously using the reader / writer 1.

Subsequently, at time t (4), the worker a has the electronic tag a3 locked on the part a at the time of finishing the processing of the part a, the electronic tag a7 locked on the card on which “processing completed” is described, and the worker a. The electronic tag a1 locked to the ID card of the user a is read simultaneously using the reader / writer 1.

Subsequently, at time t (5), the carrier a loaded the processed part a into the carrier a, and the electronic tag a3 locked on the part a and the card with the name of the carrier a described thereon were locked. Using the reader / writer 2, the electronic tag a9 and the electronic tag a2 locked to the ID card of the carrier a are simultaneously read.

Subsequently, at time t (6), the carrier a places the processed part in the shipping area a, and locks the electronic tag a3 locked to the part a and the information collection post 2 installed in the shipping area a. The electronic tag a5 and the electronic tag a2 locked to the carrier a's ID card are simultaneously read using the reader / writer 2.

By the above reading operations, the management number of the reader / writer (the management number of the reader / writer 1 is 100 and the management number of the reader / writer 2 is 200), the management code of the electronic tag (the management code of the electronic tag ax is a00x (x = 0,1,2,3,4,5,6,7,8,9)), the reading time is transmitted from the reader / writer to the information communication post, and the information communication post transmits the information to the tag information management device. I do. Upon receiving the information, the tag information management device stores the information in the tag information storage unit.

The left table in FIG. 4 shows an example of data stored in the tag information storage unit by the reading operation of the electronic tag. It is assumed that the management code of the electronic tag and the corresponding data of the target to which the electronic tag is locked are registered in the tag information storage unit as shown in the middle table of FIG. The RFID tag read data is combined with the management code corresponding data using the RFID tag management code as a key (FIG. 4, right table), and the tag information management device uses the determination logic programmed in the status determination means to determine the status of the RFID tag. It is possible to make a judgment.

By using a combination (history information set) of history information obtained from the electronic tag read data, it is possible to determine an accurate state of a target at an arbitrary time.

For example, the state determination of the component a will be described with reference to FIG.
Since the electronic tag a3 locked to the component a is read from the history information 60 at the time t (1) of the combined data in FIG. 5 at the same time as the electronic tag indicating the location of the processing site a, the component a is A determination logic for determining that the part a exists in the tag information management device, in which the determination logic is programmed, determines that the component a exists in the processing site a at the time t (1). However, the history information 60 alone cannot determine whether the transporter a has carried the object into the processing site a or has been carried out of the processing site a.

The above determination result is stored in the tag information management device as flag information. In the present embodiment, the management code of each electronic tag has a place flag and a state flag, and as shown in the place flag correspondence table and the state flag correspondence table in FIG. It is assumed that it is registered in the tag information storage unit.

Based on the result of the above determination, the state determination means executes a process of inputting 1 indicating the processing site a to the location flag of the electronic tag management code a003 and inputting 0 indicating the state unknown to the status flag.

Subsequently, from the history information 61 at time t (2) of the combined data in FIG. 5, the electronic tag a3 locked to the component a is simultaneously provided with the equipment a for performing the processing and the electronic tag indicating the worker a performing the processing. Since the part a has been read, it is possible to form a determination logic for determining that the part a has been prepared for processing using the equipment a by the worker a and is in a state of waiting for processing, and the determination logic is programmed tag information. The state determination means of the management device executes a process of changing the state flag of the electronic tag management code a003 at time t (2) to 2 indicating that the processing is waiting.

Further, from time t (1) to time t (2), there is no reading of the electronic tag management code indicating the location at the same time as the reading of the electronic tag of the component a. a determines that the location has not moved since time t (1), and does not change the location flag at time t (2).

In addition, since the component a is determined to be in the state of waiting for machining at the time t (2), it is possible to estimate that the state before the time t (2) is in preparation for machining, and the determination is made as such. The state determination means of the tag information management device in which the determination logic is programmed executes a process of changing the status flag of the electronic tag management code a003 at time t (1) from 0 indicating the status is unknown to 1 indicating the preparation for machining.

As described above, the location of the component a cannot be determined only from the history information 61, but by determining the location of the component a in combination with the history information 60, an accurate location can be determined. Although the state of the component a cannot be determined only from the history information 60, the state at a time before time t (2) can be estimated from the history information 61 to grasp the state at a continuous time. It becomes possible.

As described above, by determining a combination of a plurality of pieces of electronic tag information, it is possible to more accurately grasp the location and state of the target to which the electronic tag is locked.

In the above embodiment, in a closed system, the read data of the electronic tag is stored in the tag information management device to determine the state. In the following embodiments, the reader and the reader read the electronic tag at the same time as the reader. The writer executes a process of storing read data of the electronic tag (a set of a management code of the electronic tag that has been read at the same time, a read time, and a management number of the reader / writer that has performed the read) for the read electronic tag. .

In addition, the tag information management device makes a determination by reading the electronic tag, the changed flag information is transmitted to the reader / writer that has read the electronic tag, and the reader / writer that has received the flag information changes the corresponding management code. A process for storing the flag information in the electronic tag is executed.

In addition, data that can be read by electronic tags and flag information can be understood in an open system, such as management code correspondence data (FIG. 4), place flag and place correspondence data, and state flag and state correspondence data (FIG. 5). Is stored in each electronic tag. Hereinafter, the respective correspondence data will be collectively referred to as a code correspondence table.

By storing the history of the read data of the electronic tag, the state determination result and the code correspondence table in the electronic tag, and passing the information from the electronic tag to the electronic tag, the target to which the electronic tag is locked is a closed system. When moving between, it is possible to directly obtain information on production logistics in a closed system in the past from an electronic tag, and visualization of a mixed production logistics of a closed system and an open system is realized.

The transfer of information of the electronic tag when the object moves between closed systems will be described with reference to the embodiments shown in FIGS.

FIG. 6 is a diagram illustrating an example of transporting parts by the transportation company G, and arrows 70, 71, 72, 73, and 74 indicate processes in transporting the parts, respectively.

Company A has an electronic tag a1 for managing part a, company B has an electronic tag b1 for managing part b, and transport company G has a shipping box G-2 for managing the transportation state of the part. The RFID tag G-1 is locked on the card, and the RFID tags G-7 and G-8 are locked on the card with the work name "loading" and "unloading" to capture the work in transportation And
The company A, the company B, the company C, and the transportation company G are closed systems, and the electronic tag used in each company has a unique management code in each company.

In the process indicated by the arrow 70 in FIG. 6, the carrier G-5 receives the part a at the shipping place a of the company A, and from the electronic tag a1 locked to the part a, the electronic tag G- managed by the transportation company G. Replace with 3.

When the carrier G-5 receives the part a, the reader / writer operates the reader / writer to operate the management code (a001) from the electronic tag a1 and the processing name, the operator, the equipment used, and the processing started stored in the electronic tag a1 within the company A. The history information such as the time and the processing end time and the code correspondence table used by the company A are read and stored in the information storage unit of the reader / writer.

Subsequently, the carrier G-5 removes the electronic tag a1 locked to the component a at time t (11), and operates the reader / writer to store the information and the transmission time t stored in the information storage unit of the reader / writer. (11) is transmitted to the electronic tag G-3.
When receiving the radio wave from the reader / writer, the electronic tag G-3 associates the management code a001 in the company A, the history information in the company A, the code correspondence table used in the company A with the time t (11), and associates the information with the time t (11). It is stored in the storage unit (80 in FIG. 7).

As described above, when the target to which the electronic tag is locked moves between closed systems, information accumulated in the electronic tag managed by the source system is transferred to the electronic tag managed by the destination system. By using the management code of the source system as a key, the status of the target in the source system can be obtained directly from the electronic tag, and it is easy to track the past information of the target to which the electronic tag is locked. Becomes possible.

As things move through an open system, as shown in the process of arrows 70, 71 in FIG. 6, multiple things are grouped and contained within another, or to the process of arrow 72 in FIG. As shown, it is conceivable that an object is extracted from a set of grouped objects.
An example of information recorded on the electronic tag when the inclusion relation is formed will be described with reference to FIGS.

After the carrier G-5 replaces the electronic tag a1 locked to the part a with the electronic tag G-3 in the process indicated by the arrow 70 in FIG. 6, the electronic tag G-1 is replaced at time t (12). The part a is loaded into the locked shipping box G-2. As described above, when the object to which the electronic tag X is locked is included inside the object to which the electronic tag Y is locked, the electronic tag Y is called a child tag of the electronic tag X, and the electronic tag X is the electronic tag. It is called the parent tag of Y.

The carrier G-5 reads the tag information (management code g003, management code in company A, history information, code correspondence table) of the electronic tag G-3 locked to the component a using a reader / writer, and reads the reader / writer. In the information storage unit. Subsequently, the reader / writer reads the electronic tag G-7 locked on the card on which the work name “loading” is described, so that the parent-child relationship forming instruction is stored in the information storage unit of the reader / writer.

Subsequently, the carrier G-5 performs a writing operation of the reader / writer on the electronic tag G-1 locked to the shipping box G-2, so that the electronic tag stored in the information storage unit of the reader / writer is performed. The tag information of the tag G-3 and the parent-child relationship formation instruction are transmitted to the electronic tag G-1. When the electronic tag G-1 receives the information, the information processing unit of the electronic tag G-1 stores the tag information of the electronic tag G-3 in the information storage unit with a child relationship to the electronic tag G-1. Remember.

At the same time, the information processing unit of the electronic tag G-1 inputs a numerical value 1 to the parent-child relationship flag with the management code g003 as information belonging to the management code g001. When the value of the parent-child relationship flag changes, the change time is stored. (81 in FIG. 7)

When the parent-child relation flag with the management code y recorded as information belonging to the management code x is 1, it is determined that the electronic tag having the management code x includes the electronic tag having the management code y. However, when the parent-child relationship flag is 0, it is determined that the electronic tag having the management code x included the electronic tag having the management code y in the past. The parent-child relationship formation time and the parent-child relationship deletion time between the electronic tags can be obtained from the change time of the parent-child relationship flag recorded in the management code x.

Subsequently, the carrier G-5 receives the part b at the shipping place b of the company B at the time of the arrow 71 in FIG. 6 (time t (13)), and transports the electronic tag b1 locked to the part b. Replace with the electronic tag G-4 managed by the company G, and load the part b into the shipping box G-2 in which the electronic tag G-1 is locked. The information stored in the electronic tag G-4 when replacing the electronic tag b1 with the electronic tag G-4 and the information stored in the electronic tag G-1 when loading the part b into the shipping box G-2 are as described above. This is the same as the information stored in the electronic tag G-3 and the electronic tag G-1 when the component a is loaded into the shipping box G-2, and thus the description is omitted.
By loading the component b, information indicated by 82 in FIG. 8 is accumulated in the electronic tag G-1.

Subsequently, at the time point of the arrow 72 in FIG. 6 (time t (14)), the carrier G-5 unloads the part a from the shipping box G-2 at the receiving place c of the company C. Thus, when an arbitrary electronic tag is taken out from a set of electronic tags included as child tags of a certain electronic tag, examples of information recorded on the parent tag and the child tag are shown in FIGS.

When removing the part a from the shipping box G-2, the carrier G-5 reads the electronic tag G-3 locked to the part a with a reader / writer, and then reads the electronic tag G-3 with a work name "unloading". By reading the locked electronic tag G-8, the parent-child relationship deletion instruction of the electronic tag G-3 is stored in the information storage unit of the reader / writer.

Subsequently, by performing an operation of writing the information stored in the information storage unit of the reader / writer to the electronic tag G-1 locked to the shipping box G-2, the management code g003 and a parent-child relationship deletion instruction with the management code g003 are issued. Sent to electronic tag G-1. When the electronic tag G-1 receives the parent-child relationship deletion command, the information processing unit of the electronic tag G-1 performs a process of changing the parent-child relationship flag with the management code g003 for the management code g001 stored in the information storage unit to 0. Then, the flag change time is stored at the same time (83 in FIG. 8).

Subsequently, an operation of reading the electronic tag G-1 locked on the shipping box G-2 by a reader / writer and writing the information stored in the information storage unit of the reader / writer on the electronic tag G-3 locked on the component a. Is executed, the parent-child relationship flag change time and the transport information of the shipping box G-2, which are the history information of the electronic tag G-1, are stored in the electronic tag G-3 (84 in FIG. 8).
The transport information of the part a is the transport box G- from the time when the flag value of the management code g003 of the electronic tag G-3 locked to the part a becomes 1 to the time when the flag value becomes 0. It can be obtained by extracting from the transportation information in 2.

As described above, when the electronic tag G-1 includes the electronic tag G-3, the electronic tag G-1 is a parent tag by storing the tag information of the electronic tag G-3 in a parent-child relationship. By reading the electronic tag G-1, it is possible to acquire information as to which part was loaded in the shipping box G-2 and when, and when and where the part was processed. In addition, by storing the transport information such as when and where the truck carrying the transport box G-2 has passed in the electronic tag G-1, which is the parent tag, the electronic tag G-1 transfers the information to the transport box G-2. The transportation status of each loaded component can be obtained. Furthermore, when the electronic tag G-3, which is a child tag, is taken out from the electronic tag G-1, which is a parent tag, the history information stored in the parent tag is written into the child tag, so that the transport information of the part directly from the child tag. Can be obtained.

In FIG. 6, the information and communication posts G-9, G-10, and G-11 are installed at specific locations such as the points indicated by arrows 70, 71, and 72 at which the transport company G loads and unloads packages. By communicating with the tag information storage unit and comparing the actual work time with the plan information stored in the plan information storage unit of the tag information management device, it is possible to determine the delay of the work with respect to the plan, and Can be quickly determined to respond to the difference between the two.

As shown in FIG. 9, the plan information (left table in FIG. 9) registered in the plan information storage unit of the tag information management device from the terminal includes management code correspondence data, location flag and location correspondence data, status flag and status Using the code correspondence table of the transportation company G such as the correspondence data of the tag information, the information is converted into a format that can be compared with the flag information judged from the actual read data of the electronic tag by the plan information conversion means of the tag information management device (See the right table in FIG. 9) and stored in the plan information storage unit.

However, the electronic tag is locked in a state where connection with the network 500 is not possible, such as during the transportation from the company D to the enterprise E (arrow 73) or during the transportation from the enterprise E to the enterprise F (arrow 74) in FIG. Unable to determine if subject is behind schedule.

Therefore, the information communication posts G-9, G-10, and G-11 connected to the network 500 acquire the transportation planning information from the tag information management device, and the electronic tag G locked to the shipping box G-2. By writing "-1", the plan information can always be confirmed on site, and a prediction can be made for the plan, thereby preventing a delay in the plan.

The carrier G-5 reads the electronic tag G-1 using a reader / writer, and transmits a transmission command of planning information relating to the management code g001 of the electronic tag G-1 to the information receiving unit of the information communication post.
The information communication post G-9 transmits the management code g001 and the plan information transmission instruction 9 to the tag information management device via the network 500. Upon receiving the information, the tag information management device extracts, from the plan information storage unit, the transportation plan information of the shipping box G-2 in which the electronic tag G-1 is locked using the management code g001 as a key, and outputs the information via the network 500. The plan information is transmitted to the communication post G-9.

When the information communication post G-9 receives the transport plan information of the transport box G-2, it transmits it to the reader / writer owned by the carrier G-5, and the reader / writer stores the received transport plan information in the information storage unit. Subsequently, the carrier G-5 performs an operation of writing information to the electronic tag G-1 locked to the transport box G-2, so that the transportation plan information is stored in the electronic tag G-1.

As described above, by accumulating history information, parent-child relationship information, and plan information in the electronic tag, processing information, transport information, and plan information of the target can be obtained directly from the target to which the electronic tag is locked, Even in situations where it is not possible to connect to the network and communicate with the higher-level system, anyone can grasp what kind of background the object is in, where it is, and what kind of plan it is on. This makes it possible to quickly determine what should be done to keep the plan in time.

By searching and displaying not only the plan information but also the knowledge information of the object to which the electronic tag is locked from the external system, a deeper understanding of the object becomes possible.

FIG. 10 is a diagram showing an outline in which information stored in 2D or 3D data of a target is searched for from an electronic tag locked to the target and displayed on an electronic device.

It is assumed that an electronic tag 91 is locked to the component 90 and a terminal 30 having a function of displaying information transmitted from the knowledge management device 200 is connected to the reader / writer 20. 3D data is stored in the knowledge management device 200 as shape data of the component 90, and knowledge information such as material of the component, required accuracy, and an assembling method is registered in the feature points described in the 3D data. Shall be. The detailed description of the knowledge management device is described in Japanese Patent Application Laid-Open No. 2013-97743, and a description thereof will not be repeated.

When the operator reads the electronic tag 91 using the reader / writer, the management code 091 stored in the electronic tag 91 is stored in the information storage unit of the reader / writer. The operator operates the terminal device 30 to transmit the management code 091 and the knowledge information search command stored in the reader / writer to the tag information management device 1000 via the network 500. The tag information management device 1000 searches the tag information storage unit for a component code corresponding to the received management code 091, and transmits the component code and the knowledge information search command to the knowledge management device 200.

The knowledge management device 200 searches the 3D data of the component 90 having the component code, and transmits the 3D data to the tag information management device 1000 together with the feature points and knowledge information registered in the 3D data. Upon receiving the 3D data, the feature point, and the knowledge information of the component 90, the tag information management device 1000 transmits the 3D data to the terminal 30. Upon receiving the information, the terminal device 30 causes the information display unit to display the 3D data of the component 90, the feature points created in the 3D data, and the knowledge information registered in the feature points.

Similarly to the above, when the object whose knowledge is registered is the 2D data such as the design drawing of the part 90, the part code of the 2D data registered in the knowledge management apparatus 200 is searched by using the key as the key. It is possible to search and display 2D data in which the knowledge of is registered.

FIG. 11 shows the 3D data of the component 90 displayed on the terminal 30, feature points created in the 3D data, and knowledge information registered in the feature points.

The 3D data 32 of the component 90 is displayed on the information display unit 31 of the terminal 30, and the feature points 34 and 35 are displayed by pointing to specific coordinates of the 3D data 32. A list of feature points created in the 3D data is displayed in the feature point list 36, and by selecting each feature point, the detailed information display unit 37 displays details of the knowledge registered in the feature point.

The coordinates 38 on the 3D data corresponding to the position of the electronic tag 91 attached to the actual component 90 are specified by image processing of an image of a target to which the electronic tag is attached, and the coordinates 38 are used as a reference. A feature point having a coordinate value within a specific range 33 may be searched, and only the knowledge information registered in the feature point may be extracted and displayed.

A method of specifying coordinates on the 3D data corresponding to the position of the electronic tag in the target is performed by, for example, photographing a marker having a known three-dimensional positional relationship with the target using an imaging device, as proposed in JP-A-2002-92647. Then, the position and orientation relationship between the target and the imaging device is obtained, and the terminal 30 displays 3D data in the position, size, and orientation based on the position and orientation relationship, and displays the position of the electronic tag on the image and the position of the 3D data. Can be specified by a method of associating the coordinates of.

Further, when specifying the coordinates on the 2D data corresponding to the position of the electronic tag in the object, the knowledge management device 200 retrieves the image and shoots the component 90 from the same angle and distance as the 2D data displayed on the terminal 30. The position of the electronic tag on the photographed image is made to correspond to the coordinates on the 2D data by using the image collation technology to compare the 2D data and the photographed image, and the electronic tag is directly converted from the feature point created at the coordinates on the 2D data. It is possible to search and display knowledge about the location where the tag was attached.

By storing the feature points and the knowledge information created in the 3D data 32 of the component 90 retrieved from the knowledge management apparatus 200 from the reader / writer by operating the terminal 30 in the electronic tag 91, in a situation where connection with the network 500 is not possible. Also, knowledge information can be obtained directly from the electronic tag locked to the component.

In this way, more information required for production logistics, such as the material of the part in front, the required accuracy, the method of assembly, etc. can be obtained directly from the part in front of the object, It is possible to achieve a production logistics that is consistent with, or integrated with, information, and realizes visualization of a production logistics in which a closed system and an open system are mixed.

In addition, not only production logistics information but also related information such as quality, cost, and lead time can be obtained from the RFID tag and the location information of the RFID tag on the part. By obtaining the ideas of the planners involved in the production from the knowledge management device and displaying them on the terminal, more efficient production becomes possible.
