In order to perform RF tag information management in a system having such a hardware configuration, the following functions are provided in the management terminal device 20.
FIG. 4 is a block diagram illustrating functions of the management terminal device.

  The management terminal device 20 includes an RF tag reading unit 21, an assembly video ID generation unit (management ID generation unit / list generation unit) 22, a list storage unit 23, an RF tag writing unit 24, a data extraction unit 25, and a data storage unit 26. And a data transfer unit 27.

  When receiving the list sent from the RF reader / writer 50, the RF tag reading unit 21 sends the list to the assembly video ID generation unit 22 and notifies the data extraction unit 25 of the start of video signal extraction. Further, when the RF tag reading unit 21 receives the signal of the RF reader / writer 50 that has not detected the RF tag, the RF tag reading unit 21 notifies the data extraction unit 25 of the completion of extraction of the video signal.

The list storage unit 23 stores an edit list.
When the assembly video ID generation unit 22 receives the list from the RF tag reading unit 21, the assembly video ID generation unit 22 retrieves the editing list from the list storage unit 23, updates the contents of the editing list, and stores them in the list storage unit 23. At this time, the assembly video ID for identifying the video signal extracted by the data extraction unit 25 (for identifying the video signal when assembling the parts) is stored in the edit list. If there is no edit list, the list received from the RF tag reading unit 21 is stored in the list storage unit 23 as an edit list.

  In the present embodiment, even in a list having the same content, the list read by the RF tag reading unit 21 is simply referred to as “list”, and the list stored in the list storage unit 23 is referred to as “edit list”. Distinguish.

The RF tag writing unit 24 extracts a copy of the edit list from the list storage unit 23 and transmits the extracted edit list to the RF reader / writer 50.
The data extraction unit 25 continuously receives video signals from the imaging device 30.

  When the data extraction unit 25 receives the notification of the start of video signal extraction from the RF tag reading unit 21, the data extraction unit 25 extracts the video signal from the time when the notification is received, and ends the extraction of the video signal from the RF tag reading unit 21. When the notification is received, the extracted video signal is added with information about the date and time when the video signal extraction started, the date and time when the video signal extraction ended, and the extracted area (the assembly work area 40 in this embodiment). The video data is stored in the data storage unit 26. The date and time when the extraction of the video signal is started and the date and time when the extraction of the video signal is finished can be obtained by referring to a timer (not shown) in the management terminal device 20, for example.

The data storage unit 26 stores video data.
The data transfer unit 27 extracts the video data stored in the data storage unit 26 and transfers the extracted video data to a server (not shown).

Next, the data structure of the list and edit list stored in the RF tag will be described.
First, the data structure of a list when manufacturing a semi-finished product will be described, and then the data structure of the list when manufacturing a product will be described.

FIG. 5 is a diagram showing a data structure of a list when a semi-finished product is manufactured.
The list 90 has columns of identification numbers and time area information, and information arranged in the horizontal direction of each column is associated with each other. That is, each of the video IDs 91 to 93 and the assembly video ID 94 has an identification number and time area information.

  Identification numbers for identifying components are set in the identification number columns of the video IDs 91 to 93, respectively. Here, the attribute (connection relation) of the component is represented by “−”. That is, for example, a part having the identification number “1-1” in the video ID (hereinafter simply referred to as “part of the identification number“ 1-1 ””, and the same applies to other parts) This indicates that the component is connected to the component (subordinate component of the component with identification number “1”), and the component with identification number “1-1-1” is connected to the component with identification number “1-1”. It is shown that it is a part to be processed (subordinate part of the part having the identification number “1-1”).

  Further, the video IDs 91 to 93 of the parts carried in are arranged in the list 90 in order (time series) (in FIG. 5, from top to bottom). With this arrangement, it is possible to easily grasp the order of the parts carried into the assembly work area. In FIG. 5, the part having the identification number “1-1” is first carried in, the part having the identification number “1-1-1” is next carried in, and then the part having the identification number “1-1-2”. Indicates that it has been imported.

  Further, since the assembly is performed in the order in which the parts are carried in, by referring to the list 90, the parts with the identification number “1-1” and the parts with the identification number “1-1-1” are first assembled. Next, an assembly of a part group composed of the part with the identification number “1-1” and the part with the identification number “1-1-1” and the part with the identification number “1-1-2” is performed. You can see that

  In the time area information column of the video IDs 91 to 93, when a part is manufactured in the assembly work area, the time (year, month, hour and minute) when the part was manufactured and the name of the manufactured area are set. The When a part is purchased, information such as the date and time of purchase is set. FIG. 5 shows that, for example, a part with the identification number “1-1” was manufactured in the assembly work area A on March 27, 2006 at 10:11. By adding the area information, even when the assembly is performed in different areas, these can be easily identified.

As described above, the assembly video ID 94 has information for identifying the video signal at the time of assembling the parts, and is set at the end of the list 90.
In the part column of the assembly video ID 94, an identification number indicating that the video signal of the part is managed is set. This identification number is prefixed with “#”, and is distinguished from the identification numbers of the video IDs 91 to 93. Also, the assembly video ID 94 is one higher than the identification number “# 1-1” from the part of the identification number “1-1” obtained by removing “#” from the identification number “# 1-1” according to the time area information. Information for identifying video signals at the time of assembling the parts up to the identification number “1-1-2” is managed. Hereinafter, the identification numbers “1-1” to “# 1-1” are referred to as “component 1-1 system”. In the time area information column of the assembly video ID 94, information on the assembly start time of the component 1-1 system, information on the area, information on the assembly end time, and information on the area are arranged. FIG. 5 shows that the assembly of the component 1-1 system started at 10:23 on March 27, 2006, and ended at 10:28 on March 27, 2006.

  Next, the data structure of a list when manufacturing a product will be described. In the following description, differences from the above-described list 90 will be mainly described, and description of similar matters will be omitted.

FIG. 6 is a diagram illustrating a data structure of a list when a product is manufactured.
The list 90a stores video IDs 91 to 93, 95, 96 and assembly video IDs 94, 97.

  The video ID 95 is arranged at the top of the list 90a. A corresponding assembly video ID 97 is arranged at the bottom of the list 90a. Therefore, the assembly video ID 97 has an identification number “1-2” that is one higher than the identification number “# 1” from the part of the identification number “1” obtained by removing “#” from the identification number “# 1” according to the time area information. Information for identifying video signals at the time of assembling the parts up to the parts is managed. In addition, a part having the identification number “1”, a part of the part 1-1 series, and a part having the identification number “1-2” existing between the picture ID 95 and the assembly picture ID 97 including the picture ID 95 are the parts 1 series. Is configured. By arranging the assembly video ID for each system in the list in this way, it is possible to easily identify the structural unit of the semi-finished product even after the product is manufactured.

  The video ID 96 is arranged below the video ID 93 via the assembly video ID 94. By arranging the assembly video ID 94, it can be seen that the part having the identification number “1-1-2” and the part having the identification number “1-2” belong to separate parts groups. Also, since the identification number “# 1-2” does not exist after the component with the identification number “1-2”, and the identification number “# 1” immediately follows, the component with the identification number “1-2”. Shows that the component 1-2 is composed of only this component (no assembly with other components is performed), and that the assembly with the component with the identification number “1” is performed directly. .

  FIG. 6 also shows that the assembly of the part 1 system started in area C on March 27, 2006 at 10:45 and ended in area C on March 27, 2006 at 10:58. .

  In the following, for easy understanding, the video ID of the component with the identification number “1” is called “1 video ID”, and the video ID of the component with the identification number “1-1” is “1-1 video ID”. " The assembly video ID with the identification number “# 1” is referred to as “1-system assembly video ID”. The same applies to other cases.

Next, video data stored in the data storage unit 26 will be described.
FIG. 7 is a diagram showing video data.
The video data 80 includes a video signal storage unit 81 and a time area information storage unit 82.

The video signal storage unit 81 stores a video signal.
The time area information storage unit 82 stores information similar to the time area information included in the assembly video ID.

Next, the operation of the information management system 100 will be described.
In the following, the product to be managed is composed of n parts, and each part is represented by a part a (a = 1, 2,..., N) in which an identification number is added after the part. In addition, each part is carried into an assembly work area from a part having a small identification number.

FIG. 8 is a flowchart showing the operation of the information management system.
First, the RF reader / writer 50 determines whether or not the part a has been carried into the assembly work area 40 (step S11). When the part a has not been carried into the assembly work area 40 (No in step S11), it waits for the part a to be carried in. When it is detected that the part a has been carried into the assembly work area 40 (Yes in step S11), the RF tag included in the part a is read and the list is transmitted to the RF tag reading unit 21 (step S12).

  Next, the RF tag reading unit 21 outputs a video signal acquisition request in the assembly work to the data extraction unit 25, and outputs a list to the assembly video ID generation unit 22 (step S13). Thereby, the data extraction part 25 starts acquisition of a video signal.

  Next, the assembly video ID generation unit 22 determines whether or not a = 1 (whether or not it is a part that is first loaded into the area) (step S14). This is determined by, for example, whether or not an edit list exists in the list storage unit 23. If a = 1 (Yes in step S14), an edit list is generated (step S15), and after stored in the list storage unit 23, the process proceeds to step S22. On the other hand, when a = 1 is not satisfied (No in step S14), the assembly video ID generation unit 22 extracts the edit list stored in the list storage unit 23 (step S16). Next, it is determined whether or not a = 2 (whether or not it is the second part carried into the area) (step S17). This is determined, for example, based on whether or not an assembly video ID exists in the edit list of the list storage unit 23. If a = 2 (Yes in step S17), an assembly video ID is generated and added to the edit list (step S18). On the other hand, when a = 2 is not satisfied (when a ≧ 3) (No in step S17), the assembly video ID in the edit list is updated (step S19). Specifically, the assembly end time information of the time area information of the assembly video ID of the edit list is updated and stored in the list storage unit 23.

Next, the video ID is added to the edit list to update the edit list, and the updated edit list is stored in the list storage unit 23 (step S20).
Next, the RF tag writing unit 24 reads a copy of the edit list and transmits it to the RF reader / writer 50. Then, the RF reader / writer 50 writes the edit list to the RF tag in the assembly work area 40 (step S21).

However, the present invention is not limited to this. The entire list may be read, or the RF tag from which the list is read may be determined in advance. In this case, it is particularly preferable to preferentially read the list of RF tags exposed on the surfaces of the semi-finished product 210 and the semi-finished product 220. Thereby, a more accurate list can be acquired.

  Furthermore, it is preferable that each of the management target product 200, the semi-finished product 210, and the semi-finished product 220 is designed in advance at the time of design so that a tag that can be reliably read and written in the assembly work area 40 is arranged. As a result, the list can be reliably read from and written to the RF tag.
