1 is a schematic diagram of a system according to a first embodiment of the present invention. The flowchart of the Example which concerns on the 1st Embodiment of this invention is shown. It is a sequence diagram of the normal state which concerns on the 1st Embodiment of this invention.

[First Embodiment]
Hereinafter, an embodiment for carrying out a maintenance equipment information management system according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a system according to the first embodiment of the present invention.

[System configuration]
A maintenance equipment information management system 1 according to the present invention includes a communication network 2, a maintenance center 10, and one or more work sites 20.

  The communication network 2 is a computer network such as a LAN (Local Area Network) and the Internet. The communication network 2 may be either a wired or wireless environment, or a mixture of both, or any environment.

  The maintenance center 10 has a function of collectively managing information on one or more RFID tags 23 and devices used 25 such as work servers and communication devices. A maintenance information management apparatus 11, a maintenance information database 13, and a device information database 15 are included.

  The maintenance information management apparatus 11 transmits / receives data to / from the RFID reader / writer 21 via the communication network 2. Further, it is a device that performs control to read, write, and update the maintenance information database 13 and the device information database 15. In addition, a user interface with a user includes an input device such as a mouse and a keyboard (not shown), and a screen (display: not shown) as an output device.

  The maintenance information database 13 holds information related to the overall maintenance work, for example, the names of delivered equipment, the number of delivered equipment, maintenance conditions, work procedure manuals, etc. in a table for each work site 20.

  The device information database 15 stores information related to maintenance target devices, for example, manufacturer defect information, sales stop information, work procedures, and the like in a table for each maintenance target device.

  The work site 20 includes an RFID reader / writer 21, one or more used devices 25, and one or more portable terminals 28. An RFID tag 23 is attached to each of the used devices 25.

  The RFID reader / writer 21 is a device that reads and writes information recorded in the RFID tag 23.

  A wireless tag such as the RFID tag 23 can be classified into an active tag and a passive tag depending on the format. An active tag is a tag that has a power source in its own casing and transmits radio waves by itself. Since the radio wave is transmitted by itself, it can be transmitted to the RFID reader / writer even if it is relatively separated from the reader / writer and has a distance of several tens to several hundreds of meters.

  A passive tag is a tag that, when receiving a radio wave emitted by an RFID reader / writer, generates a radio wave by electrostatic induction of the RFID reader / writer built in the passive tag and returns information to the RFID reader / writer. Passive tags have a simple structure and can be mass-produced at low cost. Moreover, it can be easily attached to an article with a thickness of several millimeters. However, since they do not transmit themselves, the radio waves are weak, and the communication range between the passive tag and the RFID reader / writer is limited to a few millimeters for short distances and to a few meters for long distances. For this reason, if a strong radio wave is transmitted, inconvenience occurs in the surrounding environment and equipment, so it is used in factories and hospitals.

  Thus, the active tag can receive radio waves in a wide range. In addition, since passive tags receive radio waves in a narrow range, measurement errors are less likely to occur during detection, but RFID readers / writers do not receive radio waves unless they are close enough to bring the tag into contact with the RFID reader / writer. In order for the holder to read data from the RFID reader / writer, the holder must consciously approach the place where the RFID reader / writer is installed.

  In the present invention, the RFID tag 23 may use an appropriate method according to the space at the work site 20 and other conditions.

  Communication between the RFID reader / writer 21 to the RFID tag 23 uses wireless communication. As a general standard, it is preferable to use Wi-Fi (wireless fidelity: registered trademark) or IrDA (Infrared Data Association). No limitation. The current mainstream is equipment with outputs of 426 MHz, 920 MHz, 950 MHz, and 2.45 GHz. When the output is 426 MHz, communication of about 20 m is possible, which is suitable for indoor position detection and entrance / exit management. Since 920 MHz, 950 MHz, and 2.45 GHz (IEEE802.155) are capable of longer-distance communication, they are suitable for position detection outdoors.

  The used device 25 is one or more work servers, communication devices, and the like installed in the field, and is a device to be maintained. Each use device 25 has an RFID tag 23 attached thereto. It is desirable that the RFID tag 23 is attached to a predetermined position without improving the accuracy of reading / writing with the RFID reader / writer and from the viewpoint of management.

  The failed device 27 is a device that is in a state determined by the maintenance worker 30, the site manager, or the maintenance information management device 11 that the used device 25 is in a failed state. The maintenance worker 30 repairs or replaces with a replacement device 31 that is the same as or equivalent to the used device 25, thereby recovering from the failure state and returning to the used device 25.

  The portable terminal 28 includes an RFID tag reader 29 that can read the RFID tag 23. The RFID tag reader 29 may be either a built-in type or an external type in the mobile terminal 28 and can read / write the RFID tag 23. The contents of information read from the RFID tag 23 and / or related work procedure manuals and other materials are displayed on a display unit (not shown) of the portable terminal 28. Moreover, it has a storage area (not shown) in which one or more procedure manuals can be stored. As long as the portable terminal 28 can be carried by the maintenance worker 30 and can display information read from the RFID tag 23, the MS (Operation System) can be used for any OS (operating system) regardless of the device such as a laptop computer and a tablet. An OS such as Windows (registered trademark), Mac OS (registered trademark) or the like, or a mobile terminal iOS (registered trademark) or Android (registered trademark) may be used. Further, the input device may be any device such as a mouse, a touch panel, or a keyboard that can be operated by a user and input to the terminal.

[Processing flow]
Next, the processing of the present invention will be described with reference to FIGS. In this embodiment, a maintenance procedure for replacing the failed device 27 with the replacement device 31 will be described.
FIG. 2 shows a flowchart of an embodiment according to the present invention, and FIG.

  First, when a failure occurs in the use device 25 and becomes the failure device 27 (step S1), the work site 20 notifies the maintenance center 10 of the occurrence of the failure (step S2). The contact method may be e-mail, FAX, telephone or the like, and is not particularly limited. At this time, the RFID tag 23 attached to the failed device 27 (used device 25 in which the failure has occurred) is written from the RFID reader / writer 21 via the communication network 2 from the maintenance information management device 11 of the maintenance center 10. In rare cases, failure information is recorded.

  The maintenance center 10 that has received the notification selects a maintenance worker 30 to handle the failure and contacts it (step S3). In selecting the maintenance worker 30, the maintenance worker 30 is selected and contacted in consideration of experience, skill, work status, work place, and the like.

  The maintenance worker 30 who has received the notification prepares for the maintenance work such as the arrangement of the replacement equipment 31 (step S4), carries the replacement equipment 31 and the portable terminal 28, and dispatches to the work site (step). S5). At this time, information (article name, serial number, installation location, etc.) regarding the replacement device 31 and the work procedure manual relating to replacement or repair from the failed device 27 to the replacement device 31 are stored in the RFID tag 33 of the replacement device 31. Information is recorded.

  When the maintenance worker 30 arrives at the work site, it is necessary to specify the position of the failed device 27. At this time, in the RFID tag 23 of the used device 25 in which the failure has occurred, failure information for identifying the failed device 27, history information of the device, and the like are recorded in step S1. Therefore, the maintenance worker 30 can identify the failed device 27 without making a mistake with other devices by reading the RFID tag 23 with the RFID tag reader 29 connected to the portable terminal 28.

  The maintenance worker 30 uses the RFID tag reader 29 provided in the portable terminal 28 to read the RFID tag 23 attached to a predetermined position of the use device 25 mounted on a rack rack or the like. (Step S6).

  At this time, the system configuration diagram, the network configuration diagram, and the rack mounting diagram of the work target of the work site 20 are not obtained, or even if they are obtained, the information is not updated, and the configuration diagram and the actual arrangement are changed. May be different. In such a case, it is necessary to read the RFID tags 23 of several used devices 25 in order to identify the failed device 27.

  As a result of the reading, the RFID tag 23 of the used device 25 designated as the work target device by the maintenance center 10 is read, and when the reading result is the failed device 27 (Yes in step S7), it is displayed on the portable terminal 28. A message indicating that it corresponds to the work target device is displayed (step S8). If the read result is not the failed device 27 (No in step S7), it is displayed that the device is not a work target device, and the maintenance worker 30 reads the RFID tag 23 of the other used device 25 to display the failed device 27. Need to look for.

  As described above, even when the configuration is different from the actual arrangement, the failed device 27 can be specified without making a mistake based on the information of the RFID 23.

  A work procedure manual is displayed on the display unit (not shown) of the portable terminal 28 (step S8). The work procedure manual may be stored either in the maintenance information database 13 or in a storage area (not shown) of the portable terminal 28.

  The work procedure manual information recorded in the RFID tag 23 includes the URL of the work procedure manual storage location in the maintenance information database 13 and the storage location information access method for calling up the work procedure manual stored in the portable terminal 28. It is not necessary to hold the entire contents of the work procedure manual in the RFID tag 23. Therefore, the information recorded on the RFID tag 23 can be minimized, and the read / write processing load of the RFID tag 23 can be reduced.

  Then, the maintenance worker 30 performs maintenance work on the failed device 27 whose position has been specified (step S10). Specifically, a part or all of the failed device 27 is replaced with the replacement device 31 prepared in step S4 (step S11). The maintenance worker 30 can perform the replacement work without checking the work procedure of the replacement device 31 by checking the work procedure manual on the portable terminal 28.

  Then, after replacing the failed device 27 with the replacement device 31, the maintenance worker 30 withdraws from the work site (step S12).

  At the work site, the RFID reader / writer 21 reads the RFID tag 23 attached to the device 25 (periodic reading) at regular intervals (step S13). Periodic reading may be set in any unit of year, day, hour, and minute, for example, reading every day at midnight or on the first day of every month. Further, depending on the performance of the RFID reader / writer 21 and the RFID tag 23, one or a plurality of RFID tags 23 can be read, and the time can be reduced.

  The device information read by the periodic reading is transmitted to the maintenance information management apparatus 11 of the maintenance center 10 via the communication network 2 (step S14). The maintenance information management device 11 writes and records the device information transmitted to the maintenance information management device 11 in the maintenance information database 13 and the device information database 15 (step S15).

  As described above, since the device information such as the replacement of the failed device 27 with the new device 25 can be updated and stored by regular reading, the information is not complicated at the time of device replacement work. It is possible to eliminate mistakes such as mistakes in faulty equipment and incorrect procedures.

[Second Embodiment]
Usually, when the equipment 25 used at each work site 20 is delivered to the customer, a rack configuration diagram, a network configuration diagram, and the like describing the arrangement of the equipment used 25 are created, and the equipment is arranged and the rack is constructed according to the configuration diagram. . However, after delivery to the customer, there are many cases in which the customer performs physical equipment replacement or configuration change that the maintenance worker 30 is not aware of.

  In such a case, the maintenance center 10 does not know that the installation location of the equipment used has changed, so the maintenance information database 13, the equipment information database 15, the rack configuration diagram, and the network configuration diagram A state occurs in which the content is different from the actual device information and state. In such a case, when the maintenance worker 30 replaces the failed device 27, the actual arrangement is different from the rack configuration diagram and the network configuration diagram, so that it becomes difficult for the maintenance worker 30 to find the failed device 27. As a result, work delays are caused throughout the failure recovery work.

  In this embodiment, in step S15 shown in FIGS. 2 and 3, in addition to updating the maintenance information database 13 and the equipment information database 15, a program for automatically updating or creating the rack configuration diagram and network configuration diagram is provided. You may make it provide.

  The updated updated rack configuration diagram and network configuration diagram may be distributed to the replacement device 31 carried by the maintenance worker 30 when the replacement device 31 is arranged (step S4). The maintenance worker 30 can easily specify the installation location of the faulty device 27 by using the latest rack configuration diagram and network configuration diagram when performing replacement work at the work site 20, It is possible to prevent the entire system from being shortened or mistakenly taken by the failed device 27.

  The format of the rack configuration diagram and the network configuration diagram is not particularly limited, and a general configuration diagram may be automatically created / updated.

  As described above, in the maintenance equipment information management system according to the present invention, in maintenance preparation work (preparation work in the center), information corresponding to the equipment used is written to the RFID tag of the equipment used this time, A maintenance worker who has arrived at the work site can read the RFID tag with an RFID reader or the like connected to a portable terminal or the like, and can identify a faulty device that is a maintenance work target on the spot. Therefore, when replacing a failed device during maintenance work, it is possible to reliably identify the failed device before replacement and the device used for replacement, thus preventing accidents such as replacing the wrong device. it can.

  In addition, when the maintenance worker reads the RFID tag attached to the device in use at the work site with the RFID reader, the information on the work procedure manual relating to the failed device is displayed on the spot, thereby Even if the procedure is different for each device, an on-site maintenance worker can confirm an accurate work procedure without error.

  In addition, after replacing the failed device, the RFID tag attached to the device in use is periodically read, and the acquired device information is sent to the maintenance center database to update the information. Can grasp the latest status.

  In addition, when a failed device is replaced at the maintenance site, the latest device information (serial No., etc.) is confirmed by reading the device information written on the RFID tag using the RFID reader / writer. I can do it.

  The present invention can be embodied in many forms without departing from its essential characteristics. Therefore, it is needless to say that the above-described embodiment is exclusively for description and does not limit the present invention.
