Description

  The present invention relates to a suspicious component identification system and a suspicious component identification method for identifying a suspicious component to be repaired or replaced by a maintenance company that performs maintenance of various devices such as computers and printers.

  Various devices such as computers and printers used in companies are always maintained in a good state, and when a failure occurs, quick recovery is often required. Therefore, when these devices are used for business, a maintenance contract is generally concluded. When the maintenance worker receives a notification from the user who has made a maintenance contract that a failure has occurred in the relevant device, the maintenance worker grasps the failure status using a telephone or the like, prepares the relevant parts, and restores the device. Like to do.

  By the way, many devices with different functions, characteristics, or manufacturers are sold or leased, and many new products are put on the market every year, and maintenance workers who are familiar with each device are trained and secured. It has become very difficult. For this reason, particularly inexperienced maintenance workers take time to identify the fault location or, in some cases, perform misguided repairs to keep the device in a faulty state for a relatively long period of time. Inconvenience may occur. Even a person who has worked for a long time as a maintenance worker may cause a similar situation when a repair of a completely new device is requested.

  Therefore, if a failure analysis system is connected to the communication network and a failure occurs in the user's computer, the failure content is analyzed, and the analysis result is notified to the maintenance worker. It has been proposed to restore the failure by sending (see, for example, Patent Document 1). In this proposal, the failure analysis system includes a basic failure analysis tool and a database storing user information and past failure case information, and uses this to analyze failure information.

  15 and 16 show the flow of data processing at this time. As shown in FIG. 15, based on the user ID information 401 and the device ID information 402 of the failed computer, the failure analysis system 403 determines the past failure history 404 and user address / person-in-charge information 405 of the device. Then, as shown in FIG. 16, based on user ID information 401, failure computer device ID information 402, failure occurrence time 411, failure message and other detailed information 412 on the failure, the failure analysis system 403 determines the suspected component of the device. Information 413 and restoration work procedure 414 are obtained.

  Of these, the address / person-in-charge information 405 of the user destination and the suspected part information 413 are transmitted to a parts management system (not shown) and are used when sending the suspected part to the user. Also, user ID information 401, device ID information 402 of the faulty computer, fault occurrence time 411, detailed information 412, such as fault messages, past fault history 404, user address / person in charge information 405, suspected part information 413, The restoration work procedure 414 is transmitted to the maintenance worker via a maintenance worker assignment system (not shown).

As described above, in this proposal, the parts management system identifies a suspected part using information such as a failure occurrence time or a failure message obtained from the computer itself that caused the failure, and dispatches this to the user side for maintenance. It is used for replacement work of parts by workers.
JP 2001-306360 A (No. 0022, paragraph 0031, FIG. 4, FIG. 7)

  According to this proposal, the suspected part is identified based on the information of the computer itself such as a failure message of the user's computer, and the recovery work procedure corresponding to the suspected part is given to the maintenance worker. Inconveniences such as troublesome replacement work itself are eliminated. However, when the user's usage record is low with respect to the computer in which the failure has occurred, less data is obtained. Therefore, there is a problem that the specific reliability of the suspected part by the failure analysis system 403 is not necessarily high.

  Therefore, in the end, it is necessary for the maintenance worker to ask the user for information other than the failure message, or to identify the suspected component again after grasping the content of the failure at the site. As a result, when the maintenance worker is not skilled, the recovery of the failure may be greatly delayed due to re-specification and re-delivery of the suspected part. Alternatively, in order to prevent the occurrence of such a situation as much as possible, it is necessary to perform a process for selecting a maintenance worker according to the content of the failure, so that the entire maintenance worker can be efficiently utilized. could not.

  Accordingly, an object of the present invention is to provide a suspicious component identification system and a suspicious component that can accurately identify a suspicious component as a component that needs to be replaced for failure recovery without being affected by the ability of the maintenance worker. The object is to provide a component identification method.

A database in which related information related to a failure is associated with each component and (c) a database is searched for a device that has caused a failure based on the failure status input from the failure status input unit, A suspected part identifying means for performing a process of identifying a suspected part as a constituent part that needs to be replaced in order to recover from a failure, from the relationship between the related information about the plurality of constituent parts constituting the device and the failure status; (D) When the failure of the device that caused the failure is recovered, the feedback that reflects the data of the component part replaced for recovery in the suspicious component identification process by the suspicious component identification means To and a click means suspected component identifying system.

  That is, according to the first aspect of the present invention, a database in which related information related to a failure is associated with each component of these devices is obtained at the time of failure recovery. It is made to evolve according to the data to be improved, thereby improving the specific accuracy of the suspected part.

  In the invention according to claim 2, (b) failure status input means for inputting the failure status of the device in which the failure has occurred, and (b) a plurality of users of the devices to be monitored for failure collectively. A database in which related information related to a failure is associated with each component of these devices, and (c) a database for a device that has caused a failure based on the failure status input from the failure status input means. The suspected part that performs the process of identifying the suspected part as the constituent part that needs to be replaced for the recovery from the fault from the relation between the related information about each constituent part that constitutes the device and the fault status (D) When the failure of the device that caused the failure is recovered, the data for the component part replaced for recovery is reflected in the suspicious component identification process by the suspicious component identification unit. To and a readback means suspected component identifying system.

  That is, in the invention described in claim 2, a database in which related information related to a failure is associated with each component of the device for a device and a plurality of users to be monitored for the failure collectively. In addition to the evolution of the data obtained at the time of failure recovery, the database reference range can be used as a database for multiple devices for the same device and the same part, thereby improving the accuracy of identifying the suspected part. I am doing so.

  In the invention according to claim 6, (a) when a failure occurs in any of the devices to be monitored for failure, a plurality of users of the devices to be monitored for failure are collectively added to each of these devices. A search step for performing a search according to the failure status in a database in which related information related to the failure is associated with each component, and (b) a failure based on the information obtained in this search step. An accuracy display step for displaying the accuracy as a suspected component as a component that needs to be replaced in order to recover from a failure, and (c) this accuracy display step. When the failure of a device that caused a failure using the suspected component displayed in step 1 is recovered, the database update step is used to reflect the data of that component required for recovery to the database. To and a flop suspected component identifying method.

  That is, in the invention described in claim 6, a database in which related information related to a failure is associated with each component of the device for a device and a plurality of users to be monitored for the failure collectively. By using the data obtained at the time of failure recovery, the database is evolved in the database update step, thereby improving the accuracy of identifying the suspected part.

  As described above, according to the present invention, the data of the replacement part that has recovered the failure is fed back to the database, so that the database not only evolves, but the results of the work of various maintenance workers Therefore, the reliability of identifying the suspicious part is improved, and the efficiency of the work by the maintenance worker and the time until recovery from the failure can be shortened. Also, by using data related to failures for multiple users, even a user who has just installed a specific device can use the information obtained by other users to identify the suspected part. it can. As a result, even if the maintenance worker has little experience, the suspicious part can be identified and selected with high reliability.

  Hereinafter, the present invention will be described in detail with reference to examples.

  FIG. 1 shows an outline of the configuration of a suspected part identifying system in an embodiment of the present invention. The suspicious part specifying system 100 is configured such that several maintenance-related systems are connected to a communication network 101 such as the Internet, a LAN (local area network), and a public telephone network. Of these, the maintenance worker portable terminal 102 is a portable terminal carried by a maintenance worker (not shown). The maintenance worker mobile terminal 102 is a portable communication terminal such as a normal mobile phone, PHS (Personal Handy-phone System), or PDA (Personal Digital Assistant). A personal computer having a communication function and being portable may be used.

  The suspicious part estimation system 103 receives a failure occurrence status of a device to be maintained from the maintenance worker portable terminal 102 and adopts a data mining technique to estimate the suspicious part. The parts information management system 104 is a system that manages various data such as individual part configuration information of a device to be maintained, individual part failure data, and repair result data when repairs are performed. The user information management system 105 is a system that manages the configuration, operation data, past failure data, maintenance work data, and the like of a device that is a maintenance target delivered to a user. These systems 103 to 105 are realized by executing a predetermined program using a computer as will be described in detail below. The user computer device 106 is a computer device serving as a maintenance target device operating on the user side.

  FIG. 2 shows an outline of the configuration of the suspected part estimation system. The suspected part estimation system 103 includes a CPU (central processing unit) (not shown) and includes a suspected part estimation server computer 111 having a personality as a server. The suspicious component estimation server computer 111 is an information processing apparatus that controls the entire suspicious component estimation system 103, and includes a storage medium (data storage program storage medium) 112 that stores a control program for data mining, A mining component information database 113 and a data mining user information database 114 are connected. Here, the control program for data mining stored in the storage medium 112 uses a commercially available application program for data mining. The data mining component information database 113 is a database extracted and processed from the component information management system 104 for data mining. The data mining user information database 114 is a database extracted from the user information management system 105 and processed. These will be described in detail later.

  FIG. 3 shows an outline of the configuration of the component information management system. The component information management system 104 includes a CPU (not shown) and includes a component information management server computer 121 having a personality as a server. The component information management server computer 121 is an information processing apparatus that controls the entire component information management system 104, and is connected to the component information database 122, the component configuration information database 123, and the component repair information database 124, respectively. The parts information database 122 is a database that manages various information such as a management number of a maintenance part and a failure rate. The component configuration information database 123 is a database for managing component configuration information for each user computer device 106 as a device to be maintained. The parts repair information database 124 is a database that manages the results of repairing parts recovered by exchanging with new parts due to a failure.

  FIG. 4 shows an outline of the configuration of the user information management system. The user information management system 105 includes a CPU (not shown) and includes a user information management server computer 131 having a personality as a server. The user information management server computer 131 is an information processing apparatus that controls the entire user information management system 105, and is connected to the user information database 132 and the work history information database 133. Here, the user information database 132 includes a user name, a user individual management code for individually managing the user, a name of a computer as a device to be delivered to the user and subject to maintenance, a device code, and a device. It is a database that manages information such as the number of devices for each user. The work history information database 133 is a database that manages past failures, work dates such as periodic inspections or improvement works, and details of work for each user.

  FIG. 5 shows an outline of the operation of the system when a failure occurs in a user computer apparatus that has a maintenance management contract in the suspected part identification system configured as described above. Assume that a failure has occurred at a certain user computer device 106 (FIG. 1) (step S201). The user notifies the maintenance worker portable terminal 102 that a failure has occurred using a telephone such as a fixed telephone (not shown) or e-mail (step S202).

  When the maintenance worker who has the maintenance operator portable terminal 102 receives the failure call, the maintenance operator inquires the user about the failure status of the user computer device 106. At this time, the name of the user computer device 106 in which the failure has occurred and predetermined search information such as a device code are input to the maintenance worker portable terminal 102 and connected to the suspected component estimation system 103 to search for the suspected component. Is performed (step S203). The suspicious part estimation system 103 estimates the suspicious part based on the search information input for the search (step S204). The processing of step S203 and step S204 will be described in detail later.

  When the suspected part estimation system 103 estimates the suspected part, the result is returned to the maintenance worker portable terminal 102. From this estimation result, the maintenance worker portable terminal 102 issues a component dispatch instruction to replace the component as the suspected component to the component information management system 104 (step S205). The suspected part is not determined as the part that caused the failure. Therefore, the maintenance worker can select a plurality of suspected parts for one failure occurrence from the maintenance worker portable terminal 102 and ship them for failure recovery. The component information management system 104 sends the instructed suspected component to the installation location of the user computer device 106 where the failure has occurred (step S206).

  The maintenance worker portable terminal 102 is notified of the completion of the shipment of the part for replacement of the suspected part or the date and time of shipment. Accordingly, the maintenance worker can go to the installation location of the user computer device 106 in accordance with this and perform the maintenance work (step S207). Thereby, when the failure is recovered (step S208), the maintenance worker registers the work result in the user information management system 105 using the maintenance worker portable terminal 102 (step S209). This registration work realizes feedback that makes the response to the failure more appropriate.

  When the suspected part is replaced, the suspected part that has been used up to now and the suspected part sent from the parts information management system 104 that has not been used for repair remain at hand. Therefore, the maintenance worker returns these parts to the parts information management system 104 (step S210). When receiving the return, the worker of the component information management system 104 updates the data related to those components (step S211). The return identifies parts that were sent as suspected parts but were not used for parts replacement, or parts that were replaced to recover from the failure, so update the part data in a way that reflects the results. Will be done. The component update data obtained in this way is transmitted from the component information management system 104 to the suspected component estimation system 103 (step S212).

  On the other hand, the user information management system 105 updates user data using the work result sent from the maintenance worker in step S209 (step S213). This update result is transmitted to the suspected part estimation system 103 as user update data (step S214). The suspected component estimation system 103 updates the mining data using these component update data and user update data (step S215). As a result, the mining data is changed to a more appropriate one.

  FIG. 6 shows a part of the contents of the data mining component information database prepared in the suspected component estimation system. The data mining component information database 113 includes a device code 141 representing each device as the user computer device 106 (FIG. 1), a device name 142 as a general name of the device, and a failure recovery time in the device. The part name 143 of each part to be exchanged, the part number 144 for each of these parts, the number of components 145 as the number of these parts used in the corresponding device, and the suspicion of this embodiment The number of operations 146 of the same component that is maintained and managed as a whole system by the maintenance company that uses the component identification system 100, the number of failures 147 as the number of times that the component has failed so far, and the number of operations of the component A failure rate 148 as a failure rate with respect to 146 is described.

  For example, in the central processing unit represented by the device code “N1234-01”, the parts to be repaired and replaced are a CPU board, a memory card, and a power supply module. Of these, the CPU board uses a component whose component number is “P51000001”. 100 of these parts are in operation as a whole for the maintenance management of the maintenance company, and one of them has been replaced for repair so far. Therefore, the fact that the failure rate of the component is 0.01 is recorded as data up to now in the data mining component information database 113.

  FIG. 7 shows a part of the contents of the user information database for data mining prepared in the suspected component estimation system. It has already been described that the data mining user information database 114 is a database extracted and processed from the user information management system 105 shown in FIG. In the data mining user information database 114, a user name 151, a user code 152, each device name 153 with which the user has contracted maintenance management, a device code 154, and the monthly operating time of each device 155, a failure interval 156 as a time interval at which these devices cause a failure, a contracted periodic maintenance interval 157, and a monthly periodic maintenance man-hour 158 as a man-hour when averaged per month are described. It has become.

  For example, ABC Shoji Co., Ltd. represented by the user code 152 of “123-123456” has a maintenance contract for the central processing unit, etc., and the central processing unit represented by “N1234-56” operates 240 hours a month, Maintenance is performed every 180 days, and the time required for maintenance is one hour per month.

  By the way, a failure has occurred in the central processing unit constituting the user computer device 106 of ABC Shoji Co., Ltd., which has a customer contract, and the failure call in step S202 of FIG. To do. The maintenance worker listens to ABC Shoji Co., Ltd. as the name of the user who made the failure call using the maintenance worker portable terminal 102, the central processing unit as the device that caused the failure, and the failure phenomenon. If an error code is displayed by self-diagnosis of the device, ask the user for the code number. The maintenance worker connects the maintenance worker portable terminal 102 to the suspected component estimation system 103, and performs a suspected component search process based on information obtained from the user (step S203).

  FIG. 8 shows the search process of the suspected part estimation system and the process up to the reply of the result. When there is a request for searching for a suspected part from the maintenance worker portable terminal 102 (step S231: Y), the suspected part estimation system 103 receives a user name, a faulty device name, and a fault phenomenon from the maintenance worker portable terminal 102 (step S231). S232). And the data regarding the user are read from the user information database 114 for data mining shown in FIG. In this example, the device code 154 of the central processing unit of ABC Shoji Co., Ltd., whose user code 152 is “123-123456”, and data such as the operating time related to the device are read (step S233).

  By the way, in such a data mining user information database 114, the suspected part estimation system 103 extracts these data from the user information database 132 and the work history information database 133 in the user information management system 105 at an appropriate timing. It is obtained.

  FIG. 9 shows a part of the contents of the user information database. In the user information database 132, for each user, a user name 161, a user code 162, an apparatus name 163 to be maintained, an apparatus code 164, an operating system (OS) name 165, the quantity 166 of each apparatus, and a delivery date 167 is marked. Of these, information related to the user name 161, the user code 162, the device name 163, and the device code 164 is extracted and added to or changed from the data mining user information database 114.

  FIG. 10 shows a part of the contents of the work history information database. In the work history information database 133, a user name 171, a user code 172, a work date 173, a work content 174, a device name 175 where the work was performed, and a device code 176 are written for each user in relation to work such as repair. It is like that. Based on the work history information database 133, the failure occurrence interval and the time required for failure recovery for each device are obtained and reflected in the data mining user information database 114 shown in FIG. Become.

  FIG. 11 shows a part of the contents of the component information database. The part information database 122 describes a part name 181, a part number 182, a purchase price 183, a repair price 184, a failure rate 185, and a purchase destination 186 for each part to be managed.

  FIG. 12 shows a part of the contents of the component configuration information database. In the component configuration information database 123, a device code 191, a device name 192, a component name 193 constituting the device, a component number 194, and the number 195 of these components in the device are described for each device. Therefore, although not shown in this figure, if the same parts are used between different devices, these same parts will be shown in the corresponding respective devices.

  FIG. 13 shows a part of the contents of the parts repair information database. The parts repair information database 124 includes a part name 301, a part number 302, an operation count 303 as the number of operating the parts in the entire system, a failure count 304, a failure rate 305, and a detailed failure location 306. . The data mining component information database 113 shown in FIG. 6 is appropriately selected from the component information database 122 shown in FIG. 11, the component configuration information database 123 shown in FIG. 12, and the component repair information database 124 shown in FIG. Extract and configure data with timing.

  Returning to FIG. The suspicious part estimation system 103 reads a necessary data from the data mining user information database 114 shown in FIG. 7 in response to a search request from the maintenance worker portable terminal 102 (step S233), and generates a failure. Data on each component corresponding to the apparatus is read out from the data mining component information database 113 shown in FIG. 6 (step S234). In this example, since a failure has occurred in the central processing unit constituting the user computer device 106 of ABC Shoji Co., Ltd., the CPU board with the part number “P510000001”, the memory card with the part number “P51000002”, and the part number “P51000003”. The power supply module is a candidate for a suspected part.

  The suspicious component estimation server computer 111 in the suspicious component estimation system 103 shown in FIG. 2 is a data mining component information database 113 (FIG. 6) under the control of the data mining control program stored in the storage medium 112. Then, using the data mining user information database 114 (FIG. 7), the probability of failure is calculated for each of these candidate parts (step S235 in FIG. 8). In calculating the probability of failure, the general failure rate 148 of each candidate component is multiplied by the number of components 145 in the device, and the maintenance interval at ABC Shoji Co., Ltd. as a user environment is further calculated. And mathematical formulas that take into account circumstances such as the contents of maintenance work.

  For example, in this example, the failure rate 148 of the CPU board constituting the central processing unit is 0.01, the failure rate 148 of the memory card is 0.015, and the failure rate 148 of the suspicious part of the power supply module is 0.02. is there. Therefore, if the simple calculation is performed so that the estimated result of the suspected parts is simply 100% from these failure rates, the probability of the suspected parts of the CPU board is 16.7%, and the suspected parts of the memory card The probability of the power supply module as a suspected part is 33.3%. In addition to this, the failure of the CPU board based on the contents of the failure phenomenon notified from the maintenance worker portable terminal 102 or the maintenance work history extracted from the work history information database 133 shown in FIG. Predetermined correction processing is performed in consideration of the fact that the memory card and the power supply module have been stably operated in the past. As a result of using such a probability calculation formula, for example, the CPU board has a probability of 70% as a suspicious component, the memory card has a probability of 25%, and the power supply module has a probability of 5%. Will be.

  When the suspected part estimation system 103 calculates the suspected part and its probability in the failed device as described above, it automatically edits the display data to be displayed on the maintenance worker portable terminal 102 (step S236). ). Then, the data is transmitted to the maintenance worker portable terminal 102 (step S237).

  FIG. 14 shows the search result of the suspicious part sent from the suspicious part estimation system to the maintenance worker portable terminal. The maintenance worker portable terminal 102 displays the contents of the device or the like causing the failure, and also displays the estimation result of the suspected part with a probability. The maintenance worker determines the parts that are likely to be repaired while looking at the displayed probabilities, and issues a shipping instruction for these parts (step S205 in FIG. 5).

  Thereafter, when the maintenance worker actually recovers the failure (step S208), it is possible to determine which component has the failure at that stage. In addition, when the part or the like exchanged in step S210 is returned to the part information management system 104, the part information management system 104 can repair the part to be repaired and specifically specify the reason for the failure of the part. it can. These contents are transmitted to the suspected component estimation system 103 as component update data or user update data (steps S212 and S214). The suspected part estimation system 103 uses these data to update the mining data (step S215). In other words, by changing the coefficient of the probability calculation formula as the suspected part, or by adding or deleting items for calculation, the reliability of the suspected part identification method and the probability calculation result is improved. I can go.

  In the above-described embodiment, the description has been made on the assumption that periodic maintenance work is performed on the user computer device. However, when the user does not request periodic maintenance inspection and a failure occurs. The present invention can be similarly applied to a spot service requesting repair. Further, in the embodiments, the suspicious parts are estimated for the computer and its peripheral devices, but the present invention is similarly applied to the estimation of the suspicious parts for other electronic devices such as facsimile machines, copiers, and printers. can do.

  In the embodiment, it has been described that the maintenance worker directly receives the failure notification. However, the failure notification may be received via an intermediary organization such as a call center.
