Description

  The present invention relates to an asset management system.

  Usually, in asset management, the location of an asset is managed as one of the management items. And the management of the location of the asset is based on the paper management ledger or database in which the asset management number is written and the plate affixed to the asset and the installation location is registered for each asset management number. It is. When introducing a new asset or moving an installation location, the installation location corresponding to the management number is newly entered or modified in the management ledger or database so that the asset installation location can be grasped on the management ledger or database. ing. Also, when taking inventory of assets, an operator carries the inventory ledger to the asset installation location, visually checks the control number on the plate, and the installation location registered in the management ledger or database. The asset status at each installation location is managed by comparing and checking.

Although it is merchandise management technology in a distribution warehouse rather than asset management, for example, Japanese Patent Laid-Open No. 2001-225915 discloses the use of IC cards and IC tags in place of conventional bar codes to store merchandise and merchandise in the distribution warehouse. A product management system that manages locations in association with each other is disclosed.
JP 2001-225915 A

  By the way, the conventional asset management relies on the visual confirmation of the plate by the operator, and an asset management error due to a misreading of the management number is likely to occur, and the work efficiency is poor. For example, when stocktaking an asset, the registration number of a paper asset register and the registration number of a plate are sequentially confirmed by visual inspection, and a plurality of assets are inventoried sequentially.

  The present invention has been made in view of the above-described circumstances, and aims to improve asset management reliability and management efficiency.

  In order to achieve the above object, according to the present invention, management area information indicating a management area is stored in each of a plurality of management areas set in advance in an asset management area in which an asset to be managed is accommodated. A plurality of location data carrier devices, a plurality of asset data carriers each storing asset specific information for identifying the asset, and asset location information indicating the location of the asset as a specific management area A device, asset specific information and asset location information are registered for each asset, and an asset database device having a wireless communication function and an operation button for inputting an operation instruction are provided. Based on an input from the operation button Various storage information is read and displayed in a non-contact state from the location data carrier device and the asset data carrier device, and also from the asset database device. ; And a portable information communication terminal acquires and displays the registration information via a communication, to adopt solutions that.

  According to the present invention, the portable information communication terminal can be brought into the portable information communication terminal that can be carried by the operator from the location data carrier device and the asset data carrier device in a non-contact manner and via wireless communication. It is possible to capture the registration information from the asset database device and display the various storage information and registration information, so that the asset management reliability and management efficiency are greatly improved compared to the conventional asset management that relies on the visual inspection of the worker. Can be improved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a system configuration diagram of an asset management system according to the present embodiment. In this figure, reference numeral 1 is a location IC tag (location data carrier device), 2A and 2B are asset IC tags (asset data carrier device), 3 is a portable terminal (portable information communication terminal), 4 is an asset database device, and 5 is Management terminals, and A and B are assets.

  The location IC tag 1 is provided in each of a plurality of management areas set in advance in the asset management area, and stores the management area provided by itself in the IC chip as management area information. Such a place IC tag 1 transmits its stored information to the outside in a non-contact manner via radio waves.

  Here, the asset management area is an area where assets such as factories and offices should be managed, and a plurality of asset management areas are set in advance in such an asset management area. An area code is individually set for each management area, and the place IC tag 1 specifically stores the area code as management area information. In addition to such management area information, the location IC tag 1 also stores a tag identifier indicating its own tag type (that is, a location tag identifier indicating that it is a location IC tag), an issue date, and the like. Yes.

  FIG. 2 shows an example of the management area, that is, a plurality of management areas set on one floor of a factory building which is an asset management area. On one floor of a factory having a relatively large area, a plurality of management areas E1, E2, E3,... Are set like a grid. That is, FIG. 1 shows one place IC tag 1 attached to a pillar of one management area, but the place IC tag 1 is, for example, a management area E1, E2, E3,... Each is affixed to a fixed structure such as a pillar of each management area E1, E2, E3,.

  The asset IC tags 2A and 2B are affixed to the assets A and B to be managed in each management area, respectively, and asset specific information for identifying the assets A and B to which they are affixed, and assets A and B Asset location information indicating the installation location of the product as a specific management area is stored in the IC chip. Such asset IC tags 2A and 2B transmit their own stored information to the outside in a non-contact manner via radio waves, and store new information based on a write instruction by radio waves received from the outside, The stored information is updated and stored. In addition, when the assets A and B are made of metal such as iron, as the asset IC tags 2A and 2B, a metal-compatible IC that can sufficiently perform wireless communication with the outside even when attached to the metal surface. Tags are used.

  The asset location information is specifically the area code of the management area where the assets A and B are installed, and the asset specific information is the asset numbers of the assets A and B, for example. The asset IC tags 2 </ b> A and 2 </ b> B uniquely identify an asset by a tag identifier indicating its own tag type (that is, an asset tag identifier indicating an asset IC tag) and an asset management table in the asset database device 4. The IC chip also stores the KEEP number, the inventory ID for identifying the inventory work, the issue date, and the like. Assets A and B shown in FIG. 1 are, for example, installed in the management area E1 of FIG.

  The portable terminal 3 includes an operation button 3a for inputting an operation instruction and a liquid crystal display unit 3b for displaying various kinds of information as images. Based on the input from the operation button 3a, the location IC tag 1 and the asset Various stored information is read from the IC tags 2A and 2B via radio waves in a non-contact state and displayed on the liquid crystal display unit 3b. At the same time, registration information is acquired from the asset database device 4 via radio waves and displayed on the liquid crystal display unit 3b. To do. The portable terminal 3 also has a function of writing information to the location IC tag 1 and the asset IC tags 2A and 2B and a function of updating registration information of the asset database device 4.

  Here, communication between the portable terminal 3 and the location IC tag 1 and the asset IC tags 2A and 2B is performed by a communication method certified as a communication standard for the IC tag, while communication between the portable terminal 3 and the asset database device 4 is performed. Is performed by a communication method certified as a wireless local area network (LAN). The mobile terminal 3 is, for example, a PDA (Personal Digital Assistance) having both a communication function with an IC tag and a wireless LAN function.

  The asset database device 4 stores, for each asset, an asset management table in which asset-specific information, asset location information, and related information are registered, and the above-described mobile phone through one of a plurality of wireless LAN access points provided in the asset management area. A wireless communication function with the terminal 3 is also provided. The management terminal 5 is a computer for registering and correcting asset-specific information and related information in the asset database device 4, or for browsing the registered contents of the asset database device 4, and with the asset database device 4 via the LAN. It is connected. The data items in the asset management table are, for example, as follows.

a. KEEP number b. Asset number c. Asset name d. Asset type code e. Area code f. Administrative department number g. Acquisition date h. Acquisition price i. Service life j. Registrant k. Registration date l. Last updated by m. last updated

Next, an asset management method using the asset management system configured as described above will be described in detail by taking the case of FIG. 1 as an example.
First, the location IC tag 1 is pre-stored by an exclusive writing machine with an area code (management zone information) indicating the management zone E1, a location tag identifier, and an issue date, and is affixed to the pillar of the management zone E1. On the other hand, in the asset IC tags 2A and 2B, the asset numbers (asset specific information), asset location information, asset tag identifier, KEEP number, issue date, etc. of the assets A and B are stored in advance by the dedicated writing machine. , B, respectively.

[Change of installation location]
For example, when the asset A is moved from another management area (for example, the management area E6) to the management area E1, an area code indicating the management area E6 is stored in the asset IC tag 2A of the asset A as asset location information. Therefore, it is necessary to change this area code to the area code of the management area E1, which is a new installation location.

  When such an installation location change is necessary, the operator operates the touch button “change installation location” on the mobile terminal 3 to display an installation location change screen on the liquid crystal display unit 3b. The portable terminal 3 takes in the area IC tag 1, that is, the area code of the management area E 1 by holding the place IC tag 1 on the installation place change screen, and displays the installation place corresponding to the area code on the liquid crystal display unit 3 b. . That is, in the “area” on the installation location change screen, it is displayed that the management area E1 is the “first processing section” on the “first floor” of the building “processing factory”.

  Then, when the touch button “read start” is operated, the portable terminal 3 enters a state where the stored information of the asset IC tag 2A can be read. When the portable terminal 3 is held over the asset IC tag 2A in this state, the location information of the asset IC tag 2A and the asset database device 4 is automatically updated when online (when the wireless LAN is in a communicable state). That is, since it is real-time processing in the case of online, the processing is completed when the storage information of the asset IC tag 2A is read into the portable terminal 3, and the storage information of the asset IC tag is successively read one after another. The process of changing the location of the asset IC tag can be performed smoothly.

  That is, when the portable terminal 3 reads the storage information of the asset IC tag 2A following the area code of the management area E1 stored in the location IC tag 1, the portable terminal 3 uses the asset location information of the asset IC tag 2A as the location IC tag 1. In addition to updating to the management area information, the installation location of the asset management table corresponding to the asset A in the asset database apparatus 4 is changed to the management area information of the place IC tag 1. It should be noted that such a change in installation location to the asset IC tag 2A is also performed when a new asset A is introduced into the management area E1.

  Here, when the mobile terminal 3 is offline (when the wireless LAN is in a communication disabled state), the portable terminal 3 temporarily stores and holds the new installation location of the asset A, that is, the area code of the management area E1. When the touch button “registration” on the installation location change screen is operated at the stage where the communication with the asset database device 4 is restored, the mobile terminal 3 transmits the asset corresponding to the asset A by the communication via the wireless LAN. The installation location of the management table is updated to the area code of the management area E1. That is, the installation location change process can be performed even when the mobile terminal 3 is in an offline state with respect to the asset database device 4.

[Inventory work]
Next, asset inventory work will be described.
The operator operates the touch button “area inventory” displayed on the liquid crystal display unit 3b of the portable terminal 3 to display an area inventory screen as shown in FIG. 4 on the liquid crystal display unit 3b. When the portable terminal 3 reads the area code of the management area E1 stored in the place IC tag 1, the area code of the management area E1, that is, “processing factory” as the building name, “first floor” as the floor number, and the place “First processing section” as the name is set and displayed on the area inventory screen as an inventory location. The inventory location, that is, the building name, floor number, and location name can be set by selecting from the drop-down list.

  Further, when the inventory ID related to the current inventory is selected / set from the inventory ID drop-down list, the portable terminal 3 displays the inventory ID as an “inventory name” on the area inventory screen. In this state, when the touch button “acquire data” on the area inventory screen is operated, the mobile terminal 3 corresponds to the area code of the management area E1 by communicating with the asset database device 4 via the wireless LAN. The asset management table of all assets is searched, and as a search result, the KEEP number, asset number, and asset name are displayed in a list on the area inventory screen. That is, on the area inventory screen, a plurality of assets including assets A and B are displayed as assets installed in the management area E1.

  In this state, the storage information of the asset IC tags of all assets installed in the management area E1 is sequentially read by the portable terminal 3, whereby the inventory of each asset displayed as a list on the area inventory screen is performed. That is, among the assets listed on the area inventory screen, “○” is obtained as an inventory result when the corresponding asset IC tag is read by the mobile terminal 3, and inventory is not obtained when the corresponding asset IC tag is not read. As a result, “X” is displayed, and “Δ” is displayed as an inventory result when the asset asset IC tag is read although it is not acquired from the asset database device 4.

  For example, when asset-specific information and related information of asset A are acquired from the asset database device 4, when the asset-specific information of the asset IC tag 2A of asset A is read, the mobile terminal 3 performs area inventory of the inventory result of asset A “○” is displayed on the screen. Such an inventory result is transmitted from the portable terminal 3 to the asset database device 4 via the wireless LAN when the touch button “save result” in the area inventory screen is operated, and is stored as inventory information of each asset. The

  According to the present embodiment, it is possible to significantly reduce the burden on the worker and to greatly reduce the occurrence of work mistakes as compared to the conventional installation location change and inventory work by visual confirmation of the worker. Therefore, the certainty and management efficiency of asset management can be dramatically improved.

In addition, this invention is not limited to the said embodiment, For example, the following modifications can be considered.
(1) In the above embodiment, the portable terminal 3 and the asset database device 4 are connected via a wireless LAN. This is because, in recent years, the widespread use of wireless LAN has significantly reduced costs. If there is a special circumstance where the wireless LAN cannot be used, a communication method other than the wireless LAN may be used as a communication method for connecting the portable terminal 3 and the asset database device 4.
(2) The mobile terminal 3 is not limited to a PDA (Personal Digital Assistance), but may be of another type.
