It was combined with the drawing information and displayed (Patent Document 1).
JP 08-095886 A

  For this reason, it is necessary to prepare and prepare in advance information related to devices and their connection route information, and map information indicating the physical positional relationship of the devices, and layouts associated with the expansion, removal, and movement of devices. When there is a change, it is required to re-enter all the devices to be changed, the device location information, and the connection route information and correct them each time, and a large amount of man-hours are required for the operation. There was a problem.

  In addition, there is a problem that it is very difficult to find a search target cable because the connection route information for connecting the devices is routed under the floor, wall, or ceiling that is actually arranged.

  In order to solve these problems, the present invention attaches an IC tag to devices and connectors and affixes a plurality of IC tags to long cables in advance, and the devices, connectors, and cables are arranged on the layout. The purpose is to detect all IC tags and their positions with a tag reader and display them on the layout as images of corresponding devices, connectors, and cables.

  Therefore, it is possible to automatically display the devices, connectors, cables and their positions on the layout and automatically display them again when the devices are changed (added, removed, moved). It becomes possible to highlight the cable and easily perform the search.

The present invention detects the position of an IC tag to which a device, a connector, a cable, and its position are pasted on the layout, automatically displays them, and automatically redisplays when the device is changed (added, removed, moved). In addition, the search target device, connector, and cable can be highlighted and the search can be easily performed. This
(1) IC tags are affixed to devices, connectors, and cables, and the positions of the IC tags are specified and displayed on the layout, eliminating the need to prepare the positional relationship between the devices and connection cables in advance. Even if the attached cable is added / removed / moved, the latest information can be displayed on the layout very easily and automatically.

  (2) Since IC tags are attached to devices, connectors, and cables, multiple IC tags can also be attached to cables that are stretched out of the human eye (under the floor, walls, ceilings, under desks). This makes it possible to display the route on the layout easily and accurately.

  (3) If a plurality of IC tags are attached to a long cable and the same cable ID is written (or stored in association with the same cable ID at the center in association with the ID of the IC tag) Even if a plurality of IC tags are attached to the device, the operation can be simplified.

  (4) It is possible to search by designating a specific device from among the devices and highlight it on the layout to improve workability.

  The present invention attaches an IC tag to a device and a connector, and a plurality of IC tags to a long cable in advance, and when the device, connector and cable are arranged on the layout, the IC tag reader uses all IC tags and their positions. Detected and displayed the image of the corresponding device, connector, and cable on the layout.

FIG. 1 shows a system configuration diagram of the present invention.
In FIG. 1, a managed device layout display system 1 detects information read from an IC tag attached to a device, a connector, and a cable and its position, and displays the image at a corresponding position on the layout 15. In this case, the processing unit 2 and the IC tag reader 12 are configured.

  The processing device 2 is a processing device such as a personal computer. Here, the IC tag position specifying means 3, the image acquisition means 4, the display means 5, the instruction means 6, the display device 7, the article image information table 8, and the article table 9 are used. , Layout image master 10, IC tag position information table 11, and the like.

  The IC tag position specifying means 3 controls a plurality of IC tag readers 12 of variable reading radio wave intensity type, and transmits radio waves to the IC tags 13 attached to devices, connectors, and cables arranged on the layout 15 and wirelessly. Two sets of distances between the IC tag reader 12 and the IC tag 13 based on the signal strength when the information is read (or when the information cannot be read) when the information is read or the signal strength (the radio wave strength) is changed. Based on the well-known principle of triangulation, the position of the IC tag 13 on the layout 15 (position (x, y, z) on the layout 15) is specified (detected). Is.

  The image acquisition means 4 is a device, connector or cable corresponding to the position of the IC tag 13 attached to the device, connector or cable specified by the IC tag position specifying means 3 based on the information read from the IC tag 13. Are read out from the article image information table 8 and acquired.

  The display means 5 displays the layout 15 on the screen of the display device 7 and displays the image of the device, connector or cable acquired by the image acquisition means 4 at the position specified by the IC tag position specifying means 3 on the display 15. It is.

  The instruction means 6 is used to input various instructions (for example, a search instruction specifying one of a device, a connector, and a cable).

The display device 7 displays the layout 15 and the like.
The article image information table 8 is registered in advance with an image for displaying the article on the layout 15 in association with the article ID (see FIG. 11C).

  The article table 9 registers the article name in association with the article ID (see (d) in FIG. 11).

The layout image master 10 is a master in which room layouts are registered in advance.
The IC tag position information table 11 stores the position of the IC tag specified by the IC tag position specifying means 3 (position (x, y, z) on the layout 15).

  The IC tag reader 12 is an IC tag reader fixed to the ceiling of a room, and can arbitrarily change the signal intensity (radio wave intensity) to be transmitted in a step shape. The IC tag affixed to a device, connector or cable Based on the signal strength when the signal intensity to be transmitted toward is weakened sequentially from the highest and information cannot be read (or when the information can be read with the signal strength increased from the lowest sequentially), the signal strength and distance Is used to calculate the distance between the IC tag reader and the IC tag by referring to a table set by measuring the above.

  The IC tag 13 is a publicly known device that transmits relevant information when it is addressed to itself when it receives a read signal (read radio wave) from the IC tag reader 12.

  The layout 15 is a room layout in which devices, connectors, and cables are arranged, and the IC tag 13 is pasted and arranged as shown in the figure.

Next, the operation of the configuration of FIG. 1 will be described in detail according to the order of the flowchart of FIG.
FIG. 2A shows a flowchart for explaining the operation of the present invention.

  In FIG. 2A, S1 controls the IC tag reader 12 to specify the position of the IC tag 13. This is because when the IC tag position specifying means 3 in FIG. 1 controls a plurality of IC tag readers 12 to read information from the IC tags 13 attached to the devices, connectors, and cables arranged on the layout 15 and read the information. Signal strength (Signal strength when reading was first performed when increasing sequentially from the lowest strength) or Signal strength when reading could not be performed (Signal strength when reading failed after decreasing from the highest strength in sequence) Based on the above, the distance between the IC tag reader 12 and the IC tag 13 is calculated with reference to a table (not shown) registered in advance by measuring the signal intensity and the distance. Then, based on the calculated two or three (in the case of three dimensions), the position of the IC tag 11 on the layout 15 is calculated using a known method of triangulation, and the position is shown in FIG. In the IC tag position information table 11).

  S2 takes out the article image by identifying the ID. This takes out the article image of the article ID from the article image information table 8 in FIG. 11B based on the article ID read from the IC tag 13 in S1.

  In S3, the map drawing and the image diagram are displayed in an overlapping manner at the detected position. This takes out the layout drawing from the layout image master 10 and displays it on the screen of the display device 7 and displays the image superimposed on the position of the device, connector or cable taken out from the IC tag position information table 14. As a result, the product image of the product ID read from the IC tag 13 is displayed on the layout 15 at a position where the IC tag 13 is located, and the user recognizes that the entire device, connector, and cable are arranged. It becomes possible to do.

  In S4, it is determined whether all the IC tags are finished. If YES, the process ends. In the case of NO, S1 and subsequent steps are repeated for the next IC tag 13.

  As described above, when an article (apparatus, connector, cable) having the IC tag 13 affixed on the layout 15 is read, the article ID is automatically read from the IC tag 13 and the signal intensity to be read is changed and the information can be read. The position of the IC tag 13 is calculated by referring to the table based on the signal intensity (when reading is impossible) and calculating the distance between the IC tag reader 12 and the IC tag 13 (three sets in the case of three dimensions). And the article image of the article ID read at the specified position on the layout 15 can be displayed. Thereby, it is possible to automatically detect the arrangement of devices, connectors, and cables on the layout 15 (the arrangement after newly arranged, moved, discarded, and increased) and to superimpose the layout on the layout 15.

  FIG. 11C shows an example of information stored in the IC tag 13. In addition to the unique tag ID, the IC tag 13 is pre-written with an article ID or the like to which the IC tag 13 is attached as management equipment identification information, and is attached to the article (apparatus, connector, cable). In the configuration of FIG. 1, the IC tag reader 12 reads the article ID here from the IC tag 13 attached to the article.

  As described above, the article ID of the article to be affixed with the IC tag 13 is written in advance and affixed to the article (or written after being affixed), so that the article and its position can be placed anywhere on the layout 15. Can be automatically detected and the article image of the article can be displayed on the layout 15 in an easy-to-understand manner.

FIG. 3 shows a layout explanatory diagram of the present invention.
3A shows a side sectional view, and FIG. 3B shows a layout viewed from above.

  In FIG. 3A, the management device layout display system 1 shows a specific example of the management device layout display system 1 in FIG. 1, as shown in a region surrounded by a thick dotted line. A plurality of IC tag readers 12 are fixed and connected to the processing device 2 by wire or wirelessly. Then, as shown in the layout 15 outside the area surrounded by the thick dotted line, a server, a personal computer, an ATM, which are articles to which the IC tag 13 is attached, a connector and a cable for connecting them are arranged as shown in the figure.

  In FIG. 3B, a layout 15 viewed from the top is obtained by connecting articles (here, a server, an ATM, a personal computer, a connector, and a cable) as illustrated. In particular, as shown in the side sectional view of FIG. 3 (a), the cable is arranged under the floor so as not to be directly visible to the human eye, but from a plurality of IC tags attached to the cable. The distance is calculated by referring to a table prepared in advance based on the signal intensity when the information is read and the intensity of the read signal is changed and cannot be read (or the signal intensity when it is read). The position is calculated, and the image of the article (cable) is displayed at the position on the layout 15 as shown in FIG. 3A, and the layout can be automatically displayed in an easy-to-understand manner. Details will be sequentially described below.

  FIG. 4 shows a display example (1) of the present invention. According to the flowchart of FIG. 2 described above, this is because the product ID is read from the IC tag 13 affixed to the product (device, connector, cable), and the read signal intensity is changed. The distance is calculated on the basis of two sets (or three sets in the case of three dimensions) of the signal intensity when there is no signal, the position on the layout 15 of the IC tag 13 is calculated by a known method, and the position of each article Shows an example in which ● is displayed and the article image is superimposed.

  For example, the upper “server” in the display example (1) also has the signal ID when read (or when it cannot be read) with the article ID read from the attached IC tag 13 and the signal intensity at the time of reading varied. Referring to the table, the distances are respectively calculated, the position (x, y, z) on the layout 15 is calculated from these distances, and the server image of the server which is ● and the article is taken out at this position as shown in the figure. Is displayed. In addition, when the article is a “cable”, a plurality of IC tags 13 are attached to the same cable. Therefore, for example, the article “cable 1” shown in the figure is an image of ● and the article (cable 1) at a plurality of positions. (In the case of a cable, since the cables 1 and 2 are in the layout 15 shown in the drawing, they are displayed in different colors, for example, the cable 1 is blue as shown and the cable 2 is green. Color-coded display of the connection status in an easy-to-understand manner).

FIG. 5 is a flowchart for explaining the operation of the present invention.
In FIG. 5, S 11 controls the IC tag reader 12 to specify the position of the IC tag 13. This is because when the IC tag position specifying means 3 in FIG. 1 controls a plurality of IC tag readers 12 to read information from the IC tags 13 attached to the devices, connectors, and cables arranged on the layout 15 and read the information. Signal strength (Signal strength when reading is possible first when increasing sequentially from the lowest strength) or Signal strength when reading becomes impossible (Signal strength when reading becomes impossible after decreasing from the highest strength sequentially) Based on the above, the distance between the IC tag reader 12 and the IC tag 13 is calculated with reference to a table (not shown) registered in advance by measuring the signal intensity and the distance. Then, based on the calculated two or three (in the case of three dimensions), the position of the IC tag 13 on the layout 15 is calculated using a known method of triangulation, and the position is shown in FIG. ) In the IC tag position information table 14).

  S12 discriminate | determines whether it is an article. This determines whether the article ID read from the IC tag 13 in S11 is an article (device, connector). If YES, the process proceeds to S13. In the case of NO, since it is determined that the cable is not an article (device, connector), the process proceeds to S15.

    In S13, since the article (apparatus, connector) is found in YES in S12, the ID is identified and the article image is taken out. This takes out the article image of the article from the article image information table 10 based on the article ID of the device and the connector.

    In S14, the map drawing and the image diagram are displayed in an overlapping manner at the detected position. This is because the layout diagram is taken out from the layout image master 10 and displayed on the screen of the display device 7, and the image is superimposed and displayed at the position of the article (device, connector) taken out from the IC tag position information table 14 ( (Displayed as composite diagram (1) 16). Then, the process proceeds to S15. As a result, the image of the article (equipment, connector) of the article ID read from the IC tag 13 is displayed on the layout 15 at a position where the IC tag 13 is located, and the appearance of the arrangement of the equipment and connector is shown to the user. Can be recognized.

  In S15, it is determined whether all the IC tags except for the cable have been completed. If YES, the process proceeds to S16. In the case of NO, S11 and subsequent steps are repeated for the next IC tag 13.

  In step S16, the IC tag of the same cable is searched and the cable connection paths are superimposed and displayed. As shown in FIG. 6, a plurality of IC tags having the same contents are affixed to the article (cable) at regular intervals, and as described in detail in FIG. The left end) is the starting point, and the IC tag 13 at a certain distance or the IC tag 13 closest to the certain distance is repeatedly determined as the IC tag 13 of the next connected cable, and is attached to the cable. The positions of the plurality of IC tags 13 having the same contents are sequentially connected and the cables are connected.

  In step S17, it is determined whether all the cables are finished. If YES, the process ends. If no, repeat at S16 for the next cable.

  As described above, the signal ID when reading the article ID from the IC tag 13 affixed to the article (equipment, connector) arranged on the layout 15 and changing the read signal intensity (or when the reading becomes impossible) The distance is calculated based on the signal intensity), the position is calculated based on the distance, and the image of the article is displayed at the position of the article (device, connector) on the layout (S11 to S15). For the cable with the IC tag 13 attached, the IC tag 13 at a certain distance starting from the left end (or right end) or the IC tag 13 closest to the certain distance is repeatedly determined as the IC tag 13 at the next position (see FIG. 7) and a cable wiring diagram in which the cables are color-coded and connected on the layout 15 is superimposed and displayed on the layout 15. Theft is possible.

  FIG. 6 shows an explanatory diagram of the present invention (how to attach the IC tag of the connection cable). A connector is attached to both ends of the cable, and the IC tag 13 is attached to the connector. For example, IC cables are sequentially attached at regular intervals from the connector at the left end (for example, the same unique product ID representing the cable is written in the IC tag in advance. The connector has a unique ID for each connector. The article ID is written in advance).

  As described above, a plurality of IC tags 13 in which the same article ID (ID that uniquely represents the cable) is previously written are attached to a long cable as shown in the drawing at predetermined intervals. According to the procedure of the flowchart of FIG. 5, it is possible to sequentially connect the positions where the same article ID (cable) is affixed as a next connection point starting from the left end (or right end) at a certain distance or the like (FIG. 5). 7).

FIG. 7 shows an operation explanatory diagram (cable connection) of the present invention.
FIG. 7A shows an operation explanation flowchart.

  In FIG. 7, S21 searches for an IC tag attached to the same cable (i). This searches for a plurality of IC tags attached to the cable (i) (i = 0 to n) of FIG.

  In S22, the IC tag located at the leftmost is extracted (A). For example, as shown in FIG. 6, the cable (i) connected between the connector 1 and the connector 2 has an IC tag (from the connector 1) attached to the leftmost (or right) in the drawing. The IC tag attached to the cable (i) at the closest distance is extracted. Thereby, in FIG. 6, the IC tag (A) connected to the connector 1 closest to the connector 1 is extracted.

  In step S23, an IC tag that is within a certain distance with respect to the extracted IC tag, is closest to the certain distance, and is not connected is searched (B). As a result, the IC tag (B) to be connected to the IC tag (A) extracted in S22 (the IC tag closest to the connector 1 in FIG. 6) is determined.

  In S24, (A) and (B) are connected and displayed. Thereby, the IC tag (A) extracted in S22 and the IC tag (B) extracted in S23 are connected and displayed on the screen, for example, from the connector 1 of FIG. A) Further, it is possible to connect the IC tag 1 (A) to the IC tag 2 (B) as indicated by a solid line and display it on the screen.

  In S25, it is determined whether the same cable ends. In the case of YES, since the processing of S23 and S24 is completed for all IC tags attached to the same cable, the process proceeds to S26. On the other hand, in the case of NO, (B) is replaced with (A) in S26 (the IC tag searched in S23 is replaced with IC tag (A)), and S23 and S24 are repeated.

  In step S28, it is determined whether all the cables are finished. If YES, the process ends. In the case of NO, i = i + 1 is performed, and S21 and subsequent steps are repeated for the next cable (i).

  As described above, as shown in FIG. 6, with respect to the cable (i) connected between the connector 1 and the connector 2, a plurality of IC tags (a plurality of IC tags in which the same cable ID is written and sequentially pasted at a predetermined distance) are obtained. In some cases, the IC tag located at the closest distance (leftmost in FIG. 6) starting from one of the connectors is found, and the IC that is within a certain distance from this IC tag and is closest to the certain distance and is not connected. Find and connect the tags to all the IC tags attached to the cable in sequence, and connect the IC tags in order from the connector 1 as shown by the solid line as shown in FIG. It is possible to display. As a result, for a cable that is slightly hard and does not bend like a straight line, a large radius, or a thread, a plurality of IC tags having the same cable ID written thereon are affixed to the cable at regular intervals, and arranged on the layout. It is possible to automatically detect the position and automatically create and automatically display the cable connection diagram on the layout (room).
