Description

  The present invention relates to a technique for performing asset management using a wireless tag.

  In recent years, various services and systems using wireless tags are becoming popular. A radio tag (RFID (Radio Frequency IDentification) tag, also called IC tag) records tag information such as identification information in its internal memory, performs radio communication with radio tag readers using radio waves, and tags It has a function to send and receive information.

  One way to use such a wireless tag is to attach a wireless tag to an asset such as a personal computer or printer, and to obtain asset information (asset name, management number, model name, installation location, installation start date, lease / There are known methods for managing rental / purchase type, management status, etc.).

For example, in the method disclosed in Patent Document 1, when an asset with a wireless tag passes in the vicinity of a wireless tag reader provided at an entrance or the like, tag information is read from the wireless tag, and the passing position / date and time are read. Information is added and managed by the management server, and this information tries to grasp the movement of assets and the actual installation position on the management server.
JP 2004-295406 A

  However, since the method described in Patent Document 1 assumes that a wireless tag reader is provided at a specific fixed location such as an entrance / exit, for example, when an asset is moved in a living room, the wireless tag reader is separated from the installation location. If an asset is moved at a position, the movement cannot be grasped. In particular, personal computers, printers, and the like are often used while being moved in a living room or a laboratory according to business conditions, and it has been difficult to sufficiently cope with such a case with the conventional method.

  In addition, when taking inventory of assets, the manager in charge checks the assets on site and updates the asset information according to the asset status. It is common to write down necessary items in notebooks at the site and input them to the management server later, or access the management server on the spot from a personal computer brought to the site.

  However, the former method has a problem that it is difficult to perform timely input work according to the situation at the site. In addition, the latter method is inconvenient in that a personal computer or the like must be brought to the place where the asset is installed, and the input operation via a general-purpose interface such as a keyboard has a high risk of erroneous operation. Furthermore, when the asset installation location is unknown, it is necessary to update the asset information while searching for the asset. However, it is a heavy burden to perform such search and update while carrying a personal computer or the like.

  Therefore, the present invention can cope with the movement of assets in a living room when asset management is performed using a wireless tag, and can be performed in a simple and timely manner, such as updating asset information on site. The purpose is to provide a framework.

(First embodiment)
Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of an asset management system according to an embodiment of the present invention. As shown in FIG. 1, the asset management system 1 includes a management server 10 that functions as a host device, and a wireless tag reader 20 having a portable size and weight. The management server 10 and the portable wireless tag reader 20 communicate with each other. It is configured to be able to communicate with each other via the network N1. The communication network N1 may be any of a LAN, the Internet, a dedicated line, a packet communication network, a combination thereof, and the like, and includes both wired and wireless, but is connected to the portable wireless tag reader 20 via a wireless LAN access point. It is desirable to be connected. In FIG. 1, only one portable wireless tag reader 20 is shown, but a plurality of portable wireless tag readers 20 can be provided depending on the design.

  In the asset management system 1, an asset management wireless tag (asset tag) 40 that can be read by the portable wireless tag reader 20 is attached to an asset 30 to be managed (for example, an OA device such as a personal computer or a printer) with a seal or the like. 1) The tag information of the asset tag 40 is read by the portable wireless tag reader 20, and the location of the asset 30 is grasped. 2) The wireless tag for command input (hereinafter referred to as "command" by the portable wireless tag reader 20). A framework is adopted in which asset management processing is executed for the asset 30 whose location is known by reading the tag information of 50).

  The asset tag 40 and the command tag 50 store identification information of the tag itself in an internal memory, and when the power of a signal transmitted from the portable wireless tag reader 20 exceeds a predetermined value, the power is increased by the signal. It is configured to be supplied and started and to transmit tag information including its own identification information stored in the memory. Although conventional radio tags can be used as the asset tag 40 and the command tag 50, the command tag 50 is preferably in the form of a card, for example, in consideration of ease of handling when used.

  FIG. 2A is a block diagram illustrating a hardware configuration of the management server 10. As shown in FIG. 2A, the management server 10 can be configured by a general-purpose computer including hardware such as a CPU, ROM, RAM, HDD, user interface, display, and communication interface.

  FIG. 2B is a block diagram illustrating a functional configuration of the management server 10. As shown in FIG. 2B, the management server 10 includes functional units such as an asset management table 11, a command table 12, a tag reader correspondence table 13, a communication unit 14, and a control unit 15. However, each table only needs to be configured to be directly or indirectly accessible by the management server 10 and is configured as a part of the management server 10 in the figure, but other information processing apparatuses (such as a database server). May be under the control of

  The asset management table 11 stores the asset management information of the asset 30 attached with the asset tag 40 in association with the identification information of the asset tag 40 (see FIG. 3A).

  Asset management information includes, for example, asset name, management number, model name, installation related information (current installation position, transfer destination position, movement history, installation start date, etc.), lease related information (lease / rental / purchase type) Information, lease period information, etc.), management status (maintenance / repair / discard, etc.), etc.

  Data registration to the asset management table 11 is performed by, for example, assigning a management number to an asset in advance in the form of a barcode, reading the management number for each asset with a barcode reader or the like, and attaching it to the asset with a wireless tag reader. The identification information of the asset tag 40 can be read and registered in association with each other in the same manner as before.

  The command table 12 stores information (call information) necessary for executing a predetermined asset management process in association with the identification information of the command tag 50 (see FIG. 3B).

  As asset management processing, for example, processing for updating asset management information stored in the asset management table 11, processing for transmitting asset management information stored in the asset management table 11 to the portable wireless tag reader 20, The process of transmitting a control command can be considered. As information necessary for executing the asset management process, for example, the name of a program (function, subroutine) that executes the asset management process can be considered.

  As described above, the command table 12 is provided separately, and each asset management process is executed with reference to the command table 12, thereby making it easy to add or change the asset management process. However, the command program may be included in the main program (each asset management process is incorporated by so-called creation).

  The tag reader correspondence table 13 stores the identification information of the portable wireless tag reader 20 used for searching for the search target asset 30 in association with the identification information of the asset tag of the search target asset 30 (FIG. 3 (c). )reference). As identification information of the portable wireless tag reader 20, for example, a management number of the reader 20 can be used.

  For data management in each of these tables, a conventional database technology such as a relational database can be used.

  The communication means 14 is configured to be able to input / output information to / from the portable wireless tag reader 20 and other information processing devices (for example, a personal computer corresponding to the asset 30) via the communication network N1, for example, a PPP driver And a communication module such as a TCP / IP driver.

  The control unit 15 controls the operation of the entire management server 10 and, when receiving the identification information of the command tag 50 from the portable wireless tag reader 20 in the search mode, the asset 30 stored in the asset management table 11 The asset management process corresponding to the received identification information of the command tag 50 is executed with respect to the management information with reference to the command table 12 (command execution function). Such a command execution function can be realized on the management server 10 by starting a program that defines a part of the process of the asset management method of the present invention. FIG. 2B illustrates the command execution function as a function unit.

  In addition to the above processing, the control unit 15 executes various processing such as data registration processing in the asset management table 11 and the command tag table 12.

  The portable wireless tag reader 20 includes hardware similar to a normal wireless tag reader, such as a CPU, RAM, ROM, antenna, communication interface, and display. In addition, functions similar to those of a normal wireless tag reader, such as a function of reading tag information of the asset tag 40 and the command tag 50, a function of wireless communication with the management server 10, and a function of displaying various information on a display are provided. .

  However, the portable wireless tag reader 20 of this embodiment includes, as function means, a search target storage means 21 that stores identification information of the asset tag 40 attached to the search target asset 30, and a command tag 50 that can be input as a command. Command storage means 22 for storing the identification information of the asset tag 40, and when the identification information read from the wireless tag by wireless communication is the identification information of the asset tag 40 stored in the search target storage means 21 during the search mode. The asset position estimating means 23 for estimating the position of the asset 30 based on the radio field intensity of the command tag 50, and the identification information read from the wireless tag by wireless communication in the command input mode is the identification information of the command tag 50. And a command transmission means 24 for transmitting the identification information of the command tag 50 to the management server 10. It is different from Gurida (see FIG. 4). Each of these functional means is realized by the CPU executing a predetermined program (such as a program defining the method of the present invention) stored in the ROM, RAM, or the like.

  Hereinafter, based on the flowchart shown in FIG. 5, the asset management framework realized in the asset management system 1, specifically, 1) the asset 30 is obtained by reading the tag information of the asset tag 40 by the portable wireless tag reader 20. 2) A framework for executing asset management processing on the asset 30 whose location is known by reading the tag information of the command tag 50 by the portable wireless tag reader 20 will be described. In addition, each process (including the partial process to which the code | symbol is not provided) can be arbitrarily changed in order or performed in parallel in the range which does not produce contradiction in the processing content.

  First, for example, the management server 10 presents the asset management table 11 to the user, and designates the asset 30 to be searched (hereinafter referred to as “search asset 30A”) from the user, and uses it for searching the search asset 30A. The designation of the portable wireless tag reader 20 (hereinafter referred to as “search tag reader 20A”) is accepted (S100). For example, when the user wants to search for an asset whose lease period has expired, the user designates the corresponding asset as the search target asset 30 based on the asset management table 11 or the like.

  Next, the management server 10 associates the identification information of the asset tag 40 (hereinafter referred to as “search asset tag 40A”) attached to the search asset 30A with the identification information of the search tag reader 20A, and the tag reader correspondence table 13 (S101).

  Next, the management server 10 transmits the identification information of the search asset tag 40A to the search tag reader 20A (S102).

  When the search tag reader 20A receives the identification information of the search asset tag 40A, the search tag reader 20A stores the identification information in the search target storage unit 21 and shifts to a mode (search mode) for searching for the search asset 30A (S103).

  Here, the search mode refers to a state in which the search tag reader 20A is used to search for the search asset 30A, and does not necessarily need to be an operation mode that can be set in the search tag reader 20A. However, if it can be set in such a manner, it is desirable that the display of the search tag reader 20A displays that it has shifted to the search mode. Note that the search tag reader 20A may read the predetermined command tag 50 to shift to the search mode.

  After shifting to the search mode, the user carries the search tag reader 20A and the necessary command tag 50, moves within the area where the search asset 30A is considered to be installed, and starts searching for the search asset 30A. The command tag 50 is preferably carried in an envelope or the like that blocks radio waves so that an unintended command input is not made to the search tag reader 20A.

  When the search tag reader 20A that moves in accordance with the movement of the user during search receives tag information from the wireless tag by wireless communication during the search mode (S104: Yes), the search tag storage unit 21 is referred to and the received tag is received. It is determined whether the identification information included in the information is the identification information of the search asset tag 40A (S105).

  If it is not the identification information of the search asset tag 40A, the search tag reader 20A returns to S103 and continues the search mode.

  On the other hand, when the identification information included in the received tag information is the identification information of the search asset tag 40A, the search tag reader 20A estimates the position of the search asset 30A based on the radio wave intensity of wireless communication with the search asset tag 40A. Then, the result is displayed on the display (S106).

  As the estimation method, for example, the following method can be considered. The radio field intensity of the wireless communication with the search asset tag 40A is converted into a distance, and the circle area of the distance is set around the position of the search tag reader 20A that has performed the wireless communication. If wireless communication from the search asset tag 40A can be received at a plurality of locations, a plurality of the circle areas can be set, and it is assumed that the search asset 30A exists in an overlapping area of the plurality of circle areas. Can do. For the position of the search tag reader 20A, for example, a plurality of reference wireless tags are set at a fixed position, and a circular area is set in the same manner as described above based on the radio wave intensity of wireless communication with the plurality of reference wireless tags. Can be specified.

  Note that the distance from the search asset 30A is displayed based on the radio wave intensity of the wireless communication with the search asset tag 40A as an estimation result (for example, displayed at a stage such as “far”, “medium”, and “near”). You may comprise as follows.

  When the radio field intensity of the wireless communication with the search asset tag 40A falls below a certain value (S107: No), the search tag reader 20A returns to S103 and continues the search mode.

  On the other hand, if the radio wave intensity of the wireless communication with the search asset tag 40A is equal to or greater than a certain value (S107: Yes), it is determined that the user has found the search asset 30A, the mode is changed to the command input mode, and the command input is performed. Wait (S108). In addition, you may comprise so that it may display on a display that it shifted to command input mode. Alternatively, the search tag reader 20A may be configured to read a predetermined command tag to shift to the command input mode.

  In the command input mode, the user can input a command to the search tag reader 20A by causing the search tag reader 20A to read a desired command tag 50.

  When the search tag reader 20A receives tag information from the wireless tag by wireless communication during the command input mode (S109: Yes), the search tag reader 20A refers to the command storage means 22, and the identification information included in the received tag information is the command tag 50. It is determined whether it is identification information (S110).

  If it is not the identification information of the command tag 50, the search tag reader 20A returns to S108 and continues the command input mode. In addition, when the radio field intensity of the wireless communication with the search asset tag 40 falls below a certain value, the process may be configured to revert to S103 and enter the search mode.

  On the other hand, when the identification information included in the received tag information is the identification information of the command tag 50, the search tag reader 20A determines the identification information included in the received tag information, that is, the command tag read by the user as a command input. 50 identification information is transmitted to the management server 10 (S111).

  It is not always necessary to transmit at this timing. For example, the search tag reader 20A may read a predetermined command tag to execute the transmission process.

  When the management server 10 receives the identification information of the command tag 50 from the search tag reader 20A, the management server 10 refers to the tag reader correspondence table 13 to the search tag reader 20A (the portable wireless tag reader that has transmitted the received identification information of the command tag 50). The identification information of the corresponding search asset tag 40A is extracted (S112).

  Next, the management server 10 refers to the asset management table 11 and extracts the asset management information corresponding to the extracted identification information of the search asset tag 40A, and specifies it as an asset management processing target (S113).

  Next, the management server 10 refers to the command table 12 and executes an asset management process corresponding to the received identification information of the command tag 50 related to the specified asset management information (S114), and reverts to S108. To do.

  For example, when the received identification information of the command tag 50 corresponds to the process of changing the management status, the management server 10 stores the specified asset management information according to the received identification information of the command tag 50. Among them, the management status is changed to maintenance, repair, disposal, etc., and the asset management table 11 is updated.

  For example, when the received identification information of the command tag 50 corresponds to a process of transmitting the installation related information or lease related information of the search asset 30A to the search tag reader 20A, the management server 10 determines that the specified asset Installation related information or lease related information is extracted from the management information and transmitted to the search tag reader 20A. When receiving the installation related information or the lease related information from the management server 10, the search tag reader 20 </ b> A displays it on the display and presents it to the user.

  The asset management process does not have to update or output the asset management information. For example, when the received identification information of the command tag 50 corresponds to processing for transmitting a predetermined control command (for example, installation, uninstallation, initialization, etc. of a predetermined application) to the search asset 30A, The management server 10 transmits the predetermined control command to the search asset 30A via the communication network N2 as an asset management process related to the asset management information. Thereby, in the search asset 30A that has received the predetermined control command, processing according to the control command is executed.

  As described above, in the present embodiment, the user himself / herself moves with the wireless tag reader and employs a framework for searching for the asset installation location based on the intensity of the radio wave from the asset tag. It is possible to grasp the location of assets in a room that is difficult to grasp when fixedly installed.

  In addition, because the wireless tag reader used for asset search reads the command tag, the asset management processing execution command related to the discovered asset is input, so it is not necessary to transport a personal computer to the asset installation location. By using a wireless tag reader, asset management processing can be performed simply and timely on site.

  Further, since the command is input by causing the wireless tag reader to read the command tag, it is not necessary to provide a general-purpose input interface in the wireless tag reader itself (or even if it is provided, it is not necessary to use it). . Furthermore, by restricting the types of command tags carried by the user in advance, it is possible to limit the commands that can be input at the site, so that the risk of erroneous operation can be greatly suppressed.

(Other)
The present invention is not limited to the above embodiments and can be applied in various modifications.

  For example, in the above embodiment, the management server 10 refers to the tag reader correspondence table 13 to extract the identification information of the search asset tag 40A corresponding to the search tag reader 20A, and based on the extracted identification information of the search asset tag 40A. Thus, the asset management information of the asset management table 11 to be subject to asset management processing is specified, but the present invention is not limited to such a configuration. For example, when the identification information read by the search tag reader 20A from the wireless tag by wireless communication is the identification information of the command tag 50, the identification information of the read command tag 50 and the search asset stored in the search target storage means 21 The identification information of the tag 40A is associated and transmitted to the management server 10, and the management server 10 receives the identification information of the command tag 50 and the corresponding identification information of the search asset tag 40A from the search tag reader 20A. Based on the identification information of the corresponding search asset tag 40A, the asset management information of the asset management table 11 that is the target of the asset management process may be specified. In such a configuration, the tag reader correspondence table 13 is not necessary.

  Further, for example, in the command table 12, it is not always necessary to configure the identification information of the command tag 40 and the execution information of the asset management process on a one-to-one basis. The configuration may also be such that specific asset management processing execution information is associated. When configured in this way, it is possible to input a command by causing the search tag reader 20A to read the plurality of command tags 50 in an arbitrary or predetermined order, and to execute a specific asset management process.

  Further, for example, in the above-described embodiment, the search asset 30A has been described. However, by causing the search tag reader 20A to read a predetermined command tag, the search mode of the search target asset 30 can be shifted to another search mode or command. You may comprise so that input mode may be complete | finished.

  Further, for example, in the above embodiment, the search mode and the command input mode are described as separate modes, but the processing may be configured without distinguishing these two modes.

  Note that the present invention can be applied to other than the management of “assets”. If the situation is that 1) search for an object with a wireless tag and 2) execute a specific process for the searched object, the present invention can be applied to obtain the same effect as the above embodiment. it can.
