[Figure 7] Figure 7 is a flowchart showing an example of the search process performed by the wireless tag reader of the embodiment. [Modes for carrying out the invention]

[0007] The embodiments of the wireless tag reader and program will be described in detail below with reference to the attached drawings. Note that the embodiments described below are just one example of the wireless tag reader and program, and do not limit their configuration or specifications.

[0008] Figure 1 shows an example of an item management system 1 according to this embodiment. The item management system 1 is a system for managing items 10 stored in a warehouse or the like. For example, the item management system 1 is an inventory management system that manages the number of items 10, etc.

[0009] The item management system 1 comprises a wireless tag 11 attached to an item 10, a wireless tag reader 20, and a management server 30. The wireless tag reader 20 and the management server 30 are connected to each other via wired or wireless communication. The item management system 1 shown in Figure 1 has one wireless tag 11 attached to an item 10, one wireless tag reader 20, and one management server 30. However, the item management system 1 may have multiple wireless tags 11 attached to items 10, multiple wireless tag readers 20, and multiple management servers 30.

[0010] Item 10 is subject to the management of the item management system 1. For example, item 10 is a product.

[0011] The wireless tag 11 is, for example, an electronic tag, IC tag, or RF tag. The wireless tag 11 transmits and receives information stored in its storage medium via short-range wireless communication. For example, the wireless tag 11 stores identification information in its storage medium. The identification information includes type information and individual information. The type information is information for identifying the type of item 10 to which the wireless tag 11 is attached. For example, the type information is identification information for identifying a product, such as a JAN (Japan Article Number) code. The individual information is information for identifying each individual item 10 to which the wireless tag 11 is attached. For example, the individual information is information for identifying each individual product, such as an EPC (Electronic Product Code) or serial number. When the wireless tag 11 receives radio waves that read the identification information stored in its storage medium, it transmits the identification information. In other words, the wireless tag 11 transmits radio waves containing the identification information.

[0012] The wireless tag reader 20 is a reader that reads the storage medium of the wireless tag 11. The wireless tag reader 20 accepts input to identify the wireless tag 11 to be searched. The wireless tag reader 20 also emits radio waves to read the identification information stored in the storage medium of the wireless tag 11. When radio waves are transmitted from the wireless tag 11, the wireless tag reader 20 extracts the identification information by decoding the radio waves received from the wireless tag 11.

[0013] Furthermore, the wireless tag reader 20 measures the distance and direction to the wireless tag 11 based on the radio waves received from the wireless tag 11. When the wireless tag reader 20 extracts identification information that matches the search target, it identifies the wireless tag 11 with the highest radio wave intensity that propagated the extracted identification information. In other words, the wireless tag reader 20 identifies the nearest wireless tag 11. The wireless tag reader 20 then displays the distance and direction to the identified wireless tag 11. This allows the operator to pinpoint the location where the wireless tag 11 to be searched is located.

[0014] The management server 30 is a server device that stores various information about the managed items 10.

[0015] In this case, the operator may want to search for multiple items 10 of the same type. Conventionally, when type information is input as information to identify the wireless tag 11 to be searched, the wireless tag reader first displays the distance and direction to the nearest wireless tag 11 that stores the input identification information. Then, when the wireless tag reader searches for a wireless tag 11 attached to a different item 10 to be searched, if the operator finds an item 10 that has already been tagged, and the found item 10 is the closest, the wireless tag reader will again display the distance and direction to the wireless tag 11 attached to the found item 10. This prevents the operator from searching for another item 10.

[0016] Therefore, the wireless tag reader 20 accepts an operation to exclude the displayed wireless tag 11 from the search target. The wireless tag reader 20 stores the identification information of the wireless tag 11 read as the search target in the type exclusion list 223 or the individual exclusion list 224. Then, the wireless tag reader 20 excludes the wireless tag 11 specified by the identification information stored in the type exclusion list 223 or the individual exclusion list 224 from the subsequent search target wireless tags 11. As a result, the discovered article 10 is excluded from the search target. Therefore, even if the discovered article 10 is nearby, the wireless tag reader 20 does not display the distance and direction to the wireless tag 11 attached to the discovered article 10. Thereby, the operator can search for another article 10. In addition, the wireless tag reader 20 can reduce the labor of searching for a plurality of articles 10 of the same type.

[0017] Next, the hardware configuration of the wireless tag reader 20 will be described.

[0018] FIG. 2 is a block diagram showing an example of the hardware configuration of the wireless tag reader 20. The wireless tag reader 20 includes a control unit 210, a storage unit 220, a communication unit 230, an antenna control unit 240, a display unit 250, and an operation unit 260. These units are interconnected via a system bus 270 such as a data bus and an address bus.

[0019] The control unit 210 is a computer that controls the overall operation of the wireless tag reader 20 and realizes various functions of the wireless tag reader 20. The control unit 210 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU comprehensively controls the operation of the wireless tag reader 20. The ROM is a storage medium that stores various programs and data. The RAM is a storage medium that temporarily stores various programs and various data. Then, the CPU executes the programs stored in the ROM or the storage unit 220, etc. using the RAM as a work area (working area).

[0020] The storage unit 220 is a storage device such as a flash memory. The storage unit 220 stores a control program 221, a search target list 222, a type exclusion list 223, and an individual exclusion list 224. Note that the search target list 222, the type exclusion list 223, and the individual exclusion list 224 may be stored not only in the wireless tag reader 20 but also in other devices.

[0021] The control program 221 is a program for an operating system and for causing the wireless tag reader 20 to exhibit its functions. The control program 221 includes a program for causing the characteristic functions according to the present embodiment to be exhibited.

[0022] The search target list 222 is information having one or more pieces of type information indicating the type of the article 10 to be searched. The type exclusion list 223 is information having one or more pieces of type information to be excluded from the search target. The individual exclusion list 224 is information having one or more pieces of individual information to be excluded from the search target.

[0023] The communication unit 230 is an interface for performing communication with an external device. For example, the communication unit 230 performs communication with the management server 30 by mobile communication or wireless LAN (Local Area Network).

[0024] The antenna control unit 240 is connected to the antenna 241. Also, the antenna control unit 240 controls the radio wave intensity radiated by the antenna 241.

[0025] The antenna 241 is a device that radiates radio waves to the wireless tag 11 and receives radio waves radiated by the wireless tag 11. Also, the antenna 241 mutually converts current and radio waves.

[0026] The display unit 250 is a display device that displays various screens. For example, the display unit 250 is a liquid crystal display.

[0027] The operation unit 260 is an input device that accepts various operations. For example, the operation unit 260 may be a button provided on the wireless tag reader 20, a touch pad or touch panel provided on the display unit 250, or any other device.

[0028] Next, the functions of the wireless tag reader 20 will be described. Figure 3 is a block diagram showing an example of the functional configuration of the wireless tag reader 20 according to this embodiment.

[0029] The CPU in the control unit 210 of the wireless tag reader 20 loads the control program 221 stored in the memory unit 220 into the RAM and generates each functional unit in the RAM by operating according to the control program 221. As a result, the control unit 210 of the wireless tag reader 20 includes, as functional units, a search target input unit 2001, a wireless tag reading unit 2002, a position estimation unit 2003, a display control unit 2004, a search list generation unit 2005, an individual exclusion unit 2006, and a type exclusion unit 2007.

[0030] The search target input unit 2001 accepts one or more type information indicating the type of item 10 to be searched. The search target input unit 2001 is an example of an input means. For example, the search target input unit 2001 accepts input of type information indicating the type of item 10 to be searched on the input screen 2100 (see Figure 4). Alternatively, the search target input unit 2001 may accept the name of the item 10 to be searched. In this case, the search target input unit 2001 obtains type information corresponding to the name of the item 10 to be searched from the management server 30. Thus, the search target input unit 2001 may accept input of type information.

[0031] The wireless tag reader 2002 reads the wireless tag 11 which stores type information. The wireless tag reader 2002 is an example of a reading means. More specifically, the wireless tag reader 2002 controls the antenna control unit 240 to cause the antenna 241 to emit radio waves for reading the wireless tag 11. The wireless tag reader 2002 also extracts identification information by decoding the radio waves received by the antenna 241. As a result, the wireless tag reader 2002 reads the wireless tag 11 which stores type information and individual information for identifying the item 10.

[0032] The position estimation unit 2003 estimates the location of the wireless tag 11 based on the radio waves propagated by the identification information read from the wireless tag 11 by the wireless tag reading unit 2002. More specifically, the position estimation unit 2003 estimates the distance from the wireless tag 11 to the wireless tag reading device 20 based on the radio wave intensity of the radio waves propagated by the identification information. The position estimation unit 2003 also estimates the direction in which the wireless tag 11 is located based on the direction in which the radio waves propagating the identification information were received and the direction of the antenna 241 that was pointed at the time the radio waves propagating the identification information were received.

[0033] Furthermore, the position estimation unit 2003 estimates whether or not the wireless tag 11 is located near the wireless tag reader 20. In other words, the position estimation unit 2003 estimates whether or not the wireless tag 11 is located within a nearby distance. Nearby distance is a set distance. For example, when the position estimation unit 2003 reads the wireless tag 11, it gradually reduces the power used by the antenna 241 to radiate radio waves. Then, if the position estimation unit 2003 can read identification information from the wireless tag 11 when the antenna 241 radiates radio waves with less power than the set power, it estimates that the wireless tag 11 is located within a nearby distance.

[0034] The display control unit 2004 causes the display unit 250 to display various screens. For example, the display control unit 2004 displays an input screen 2100 that accepts one or more type information indicating the type of item 10 to be searched. Figure 4 is an explanatory diagram showing an example of the input screen 2100. The input screen 2100 includes a type information input field 2101, a type information display field 2102, an add button 2103, a delete button 2104, a delete all button 2105, and a search button 2106. The type information input field 2101 is a field for inputting type information indicating the type of item 10 to be searched. The type information display field 2102 is a field for displaying the type information that has been added as the type of item 10 to be searched.

[0035] The Add button 2103 adds the type information entered in the type information input field 2101 as the type of the item 10 to be searched. The Delete button 2104 deletes the type information that has been added as the type of the item 10 to be searched. For example, the Delete button 2104 accepts the operation to delete the type information selected in the type information display field 2102. The Delete All button 2105 deletes all of the type information that has been added as the type of the item 10 to be searched. For example, the Delete button 2104 accepts the operation to delete all the type information in the type information display field 2102. The Search button 2106 accepts the operation to finish entering the type information indicating the type of the item 10 to be searched and start searching for the wireless tag 11.

[0036] For example, the display control unit 2004 displays a search screen 2200 that shows the location of a wireless tag 11 that stores the same type information as the type information received by the search target input unit 2001, based on the reading result of the wireless tag 11 by the wireless tag reading unit 2002. The display control unit 2004 is an example of the first display means. Figure 5 is an explanatory diagram showing an example of the search screen 2200. The search screen 2200 has a location display area 2210, a type information display area 2220, an individual information display area 2221, a stop button 2201, a next type button 2202, a next number button 2203, an end button 2204, a search list button 2205, and a back button 2206.

[0037] The location display area 2210 is an area that displays the location of the wireless tag 11. The location display area 2210 displays a first mark 2211 indicating the location of the wireless tag reader 20 and a second mark 2212 indicating the location of the wireless tag 11. The display control unit 2004 displays the second mark 2212 in the location display area 2210 based on the direction and distance to which the wireless tag 11 is located, as estimated by the location estimation unit 2003.

[0038] The display control unit 2004 selects identification information from the identification information read from the wireless tag 11 by the wireless tag reading unit 2002 that has the type information entered on the input screen 2100. That is, the display control unit 2004 selects identification information that has the type information registered in the search target list 222. The display control unit 2004 also excludes identification information that has type information registered in the type exclusion list 223 and individual information registered in the individual exclusion list 224. Furthermore, the display control unit 2004 identifies the identification information with the strongest radio wave intensity that propagated the identification information from among the remaining identification information that was not excluded. Then, based on the estimation result of the position estimation unit 2003, the display control unit 2004 displays the second mark 2212 at the position of the wireless tag 11 that stores the identified identification information.

[0039] Thus, the display control unit 2004 does not display the location of the wireless tag 11 that stores the individual information registered in the individual exclusion list 224 by the individual exclusion unit 2006. Furthermore, the display control unit 2004 does not display the location of the wireless tag 11 that stores the category information registered in the category exclusion list 223 by the category exclusion unit 2007. This allows the operator to search for the next item 10.

[0040] The type information display area 2220 is an area that displays type information from the identification information read from the wireless tag 11 corresponding to the second mark 2212 displayed in the position display area 2210. In other words, the type information display area 2220 is an area that displays type information propagated by the radio wave with the strongest signal strength. The individual information display area 2221 is an area that displays individual information from the identification information read from the wireless tag 11 corresponding to the second mark 2212 displayed in the position display area 2210. In other words, the type information display area 2220 is an area that displays individual information propagated by the radio wave with the strongest signal strength.

[0041] The stop button 2201 accepts the operation to stop the search for the wireless tag 11. The next type button 2202 accepts the operation to change the type information of the wireless tag 11 to be displayed in the location display area 2210 from the identification information entered on the input screen 2100 to the next type information. In other words, the next type button 2202 accepts the operation to exclude the type information of the wireless tag 11 to be displayed in the location display area 2210 from the search target. The next number button 2203 accepts the operation to change the individual information of the wireless tag 11 to be displayed in the location display area 2210 from the identification information entered on the input screen 2100 to the next individual information. In other words, the next number button 2203 accepts the operation to exclude the type information of the wireless tag 11 to be displayed in the location display area 2210 from the search target.

[0042] Here, when the display control unit 2004 initially displays the search screen 2200, it displays the next type button 2202 and the next number button 2203 in a grayed-out or otherwise unselectable state. The operator of the wireless tag reader 20 may not have found the wireless tag 11 if the distance to the wireless tag 11 is greater than or equal to the proximity distance. However, if the next number button 2203 is pressed, the wireless tag 11 is excluded from the display target. In this case, the operator will not be able to find the wireless tag 11. Therefore, the display control unit 2004 makes the next number button 2203 selectable when the distance to the wireless tag 11 is less than the proximity distance. That is, the display control unit 2004 makes the next number button 2203 selectable when it is estimated that the item 10 to be searched has been found. In other words, the next number button 2203 accepts an operation to exclude the wireless tag 11 from the display target when the distance to the wireless tag 11 at the position displayed by the display control unit 2004 is less than a threshold. The next number button 2203 is an example of the first operating means.

[0043] The operator of the wireless tag reader 20 may want to collect items 10 with wireless tags 11 of a specific type from the type information entered on the input screen 2100 in advance. In such cases, if the type information of the wireless tag 11 displayed in the position display area 2210 does not indicate the type of item 10 to be collected in advance, the operator can collect the desired item 10 by excluding it from the display target early. Therefore, when the position of the wireless tag 11 is displayed in the position display area 2210, the display control unit 2004 displays the next type button 2202 as selectable. That is, the next number button 2203 accepts an operation to exclude from the display target wireless tags 11 that store the same type information as the wireless tag 11 that stores the same type information as the wireless tag 11 that stores. The next number button 2203 is an example of a second operating means.

[0044] The End button 2204 accepts the operation to end the search for the wireless tag 11. The Search List button 2205 accepts the operation to display a list of items 10 to which the searched wireless tag 11 is attached. The Back button 2206 accepts the operation to display the input screen 2100.

[0045] The display control unit 2004 displays the search list screen 2300 when the search list button 2205 is pressed. Figure 6 is an explanatory diagram showing an example of the search list screen 2300. The search list screen 2300 has a list showing the name of the item 10 and the number of items found for each type of information received by the search target input unit 2001. That is, the display control unit 2004 displays the name of the item 10 identified by the type of information and the number of wireless tags 11 excluded by the individual exclusion unit 2006 for each type of information received by the search target input unit 2001. The display control unit 2004 is an example of a second display means. The operator can grasp the search results up to the present time from the search list screen 2300. The search list screen 2300 also has a back button 2301. The back button 2301 is a button that accepts the operation to display the search screen 2200.

[0046] The search list generation unit 2005 generates a list of items 10 to which the searched wireless tags 11 are attached. More specifically, for each type of item information received by the search target input unit 2001, the search list generation unit 2005 generates a list containing the name of the item 10 identified by the type of item information and the number of items searched. The search list generation unit 2005 obtains the name of the type of item information received by the search target input unit 2001 from the management server 30.

[0047] Here, when the operator finds an item 10 with a wireless tag 11 attached, the wireless tag 11 attached to the found item 10 is excluded from the search target. The search list generation unit 2005 counts the number of individual pieces of information excluded from the search target for each type of information as the number of items searched. That is, the search list generation unit 2005 counts the number of times the next numbered button 2203 shown in Figure 5 is pressed for each type of information. In this way, the search list generation unit 2005 generates a list of items 10 to which the searched wireless tags 11 are attached.

[0048] The individual exclusion unit 2006 excludes the wireless tag 11 whose location has been displayed by the display control unit 2004 from the display target. The individual exclusion unit 2006 is an example of the first exclusion means. More specifically, the individual exclusion unit 2006 excludes the wireless tag 11 from the display target when the next number button 2203 is activated. That is, the individual exclusion unit 2006 registers the individual information read by the wireless tag reading unit 2002 in the individual exclusion list 224.

[0049] The type exclusion unit 2007 excludes wireless tags 11 that store the same type information as the wireless tag 11 stored at the position displayed by the display control unit 2004 from the display target. The type exclusion unit 2007 is an example of a second exclusion means. When the next type button 2202 is operated, the type exclusion unit 2007 excludes wireless tags 11 that store type information from the display target. That is, the type exclusion unit 2007 registers the type information read by the wireless tag reading unit 2002 in the type exclusion list 223.

[0050] Next, the search process performed by the wireless tag reader 20 will be described. Here, Figure 7 is a flowchart showing an example of the search process performed by the wireless tag reader 20 of the embodiment.

[0051] The display control unit 2004 displays an input screen 2100 for inputting type information indicating the type of item 10 to be searched (step S1).

[0052] The search target input unit 2001 generates a search target list 222 having one or more type information entered on the input screen 2100 (step S2).

[0053] The display control unit 2004 displays a search screen 2200 for searching for wireless tags 11 that store type information included in the search target list 222 (step S3).

[0054] The wireless tag reader 2002 determines whether or not it has read the wireless tag 11 that stores the type information included in the search target list 222 (step S4). If it has not read the wireless tag 11 that stores the type information included in the search target list 222 (step S4; No), the wireless tag reader 2002 waits in step S4.

[0055] When a wireless tag 11 that stores type information included in the search target list 222 is read (step S4; Yes), the display control unit 2004 displays the location of the wireless tag 11 in the location display area 2210 (step S5).

[0056] The display control unit 2004 enables the next type button 2202 (step S6). That is, the display control unit 2004 displays the next type button 2202 as selectable.

[0057] The display control unit 2004 determines whether the following type button 2202 has been pressed (step S7).

[0058] If the next type button 2202 is pressed (step S7; Yes), the type exclusion unit 2007 registers the type information stored in the wireless tag 11 to be displayed in the position display area 2210 into the type exclusion list 223 (step S8).

[0059] If the next type button 2202 is not pressed (step S7; No), the display control unit 2004 determines whether the distance from the wireless tag reader 20 to the wireless tag 11 is less than the proximity distance (step S9). If it is not less than the proximity distance (step S9; No), the wireless tag reader 20 proceeds to step S7.

[0060] If the distance is less than the nearest distance (step S9; Yes), the display control unit 2004 enables the next number button 2203 (step S10). That is, the display control unit 2004 displays the next number button 2203 as selectable.

[0061] The display control unit 2004 determines whether the next number button 2203 has been pressed (step S11). If the next number button 2203 has not been pressed (step S11; No), the wireless tag reader 20 proceeds to step S7.

[0062] If the next number button 2203 is pressed (step S11; Yes), the individual exclusion unit 2006 registers the individual information stored in the wireless tag 11 to be displayed in the position display area 2210 into the individual exclusion list 224 (step S12).

[0063] Then, the management server 30 proceeds to step S7.

[0064] As described above, the wireless tag reader 20 according to this embodiment accepts input of type information indicating the type of item 10 to be searched. The wireless tag reader 20 also reads a wireless tag 11 that stores the type information. The wireless tag reader 20 also displays the location of the wireless tag 11 that stores the type information based on the radio waves transmitted from the wireless tag 11. The wireless tag reader 20 then excludes the wireless tag 11 whose location has been displayed from the display targets. That is, the wireless tag reader 20 excludes the wireless tag 11 that has been discovered by the operator by displaying its location from the display targets and displays another wireless tag 11 that stores the type information. As a result, the wireless tag reader 20 displays another wireless tag 11 that stores the input type information even if the individual identification information of the items to be searched is not input. Therefore, since it is not necessary to input the individual identification information of the items to be searched, the wireless tag reader 20 can reduce the effort required to search for items 10 using the wireless tag 11. Furthermore, the wireless tag reader 20 registers the read wireless tag 11 in the type exclusion list 223 or the individual exclusion list 224.
