Description

  The present invention relates to a technical field of a part information management system and a part information management method for managing each of a plurality of products by storing component parts in a database so as to be readable.

  A general product is configured by assembling a plurality of parts, and the component parts are designed by a manufacturer that is a manufacturer. Product components vary widely depending on the type of product. In the distribution process of a product after the manufacturer's design stage, identifying what the component is like is a part of the distribution process. It is also important from the viewpoint of improving the operational efficiency of those involved in the stage. As specific examples of “stages in the distribution process” here, in the case of the manufacturer, the manufacturing stage where the product is actually manufactured according to the design content determined in the design stage, the manufactured product is inspected, and quality assurance is performed. There is an inspection stage to perform In addition, there are a sales stage in which a product shipped from a manufacturer is sold to a customer at an affiliated sales company, and a maintenance stage in which various maintenance such as product repair and maintenance is performed after the sales to the customer. The sales stage and the maintenance stage may be performed in the manufacturer or in an affiliated company outside the manufacturer.

  On the other hand, manufacturers usually handle a wide variety of products, and there is a limit to managing the component parts of each product with hard copies such as documents. Therefore, a management system that efficiently manages the component parts of each product using an information processing device such as a computer has been proposed. For example, Patent Document 1 discloses a technique related to a device management system that can easily perform work at the time of component replacement by performing appropriate information management of a device including a plurality of components. . Patent Document 2 discloses a technique for storing a change history of component parts of a product in consideration of the fact that parts may be changed during maintenance work such as repair in a completed product. .

JP 2006-285891 A JP 2006-268560 A

  As described above, the component parts of the product are defined according to the design contents created by the design department in principle. However, in practice, component parts may be changed as necessary in each stage in the distribution process after the design stage. For example, in the manufacturing stage, there is a case where a similar part that is compatible with the part specified in the design content is used among the stock parts for early disposal of the stock parts. In addition, in the inspection stage, parts may be appropriately changed so as to satisfy the product specifications according to the result of the quality determination of the inspection test. Also, at the sales stage, there are cases where replacement of parts such as attachment of dealer options and relatively simple modifications according to customer requests may be performed. In the maintenance stage, parts may be changed in accordance with the contents of the work (for example, maintenance work associated with periodic inspections, repairs performed when a failure occurs, response to a recall occurring in a specific part, etc.). In this way, in actual products, there are cases where parts different from the parts in the initial design stage are used, and the actual situation is that the constituent parts are slightly different for each model / unit.

  Conventionally, when managing product components on a database, component data in accordance with the design content created by the design department has been converted to data, but component changes made at each stage after the design phase The information was interrupted during each stage, and seamless information management was not performed. In Patent Document 2, when a repair accompanied by a component change is performed, the content of the change can be stored as a change history. However, various component changes that can be made in each distribution stage from the product design stage are described. Can't manage enough. Therefore, there is a problem that accurate parts management reflecting part changes at each stage is not performed, and the quality and efficiency of work at each stage must be insufficient. For example, in the maintenance stage, it is necessary to collect the parts required for the work prior to the maintenance work, but it is not possible to accurately grasp the various parts changes that can be made in each distribution stage from the product design stage. For this reason, the number of operations increases, resulting in inefficiency. In the inspection stage, the product characteristic parameters are compared with a threshold value by performing a trial run of the product, and the quality of the operation is determined. However, the threshold value reflects the components in the design stage. For this reason, if a component is changed at another stage (for example, a manufacturing stage before the inspection stage), the threshold used for the test needs to be corrected according to the change. Such correction is impossible if the above is not grasped. As described above, since accurate component management that reflects component changes performed at each stage of the distribution process has not been properly performed, it takes time to collect and organize information related to component changes. There is a problem that the efficiency and quality of the product are insufficient.

  In addition, depending on the type of product, there are some products in which the components are frequently changed for each product according to the customer's request. In particular, products such as large-sized products, such as power plants using stationary engines, are often manufactured as custom-made products according to customer demands, and the specifications differ finely for each individual. In such a case, in addition to the types of products on the catalog, the component parts are often different for each customer, and it is difficult to sufficiently manage with the above technique.

  The present invention has been made in view of the above problems, and provides a component information management system and a component information management method capable of improving work efficiency and quality by accurately managing components for each individual product. With the goal.

  In order to solve the above problems, the parts information management system according to the present invention manages each of a plurality of products by storing the component parts in a database so as to be readable. The database includes the products. For each type, a basic part information database that stores basic part information indicating component parts defined in the design stage, and part change information that indicates a change history of the component parts that has been performed for each of the plurality of products A component change information database to be stored in association with the component information, acquiring basic component information and component change information of the specified product from the basic component information database and the component change information database, and configuring the product A processing unit that outputs parts as a component list and an output from the processing unit are displayed. Characterized by comprising a display unit.

  According to the component information management system of the present invention, basic component information and component change information of a specified product are acquired from the basic component information database and the component change information database, and the component parts of the product are output as a component list. As a result, even if changes are made to the components set at the design stage, accurate component parts can be managed for each individual product, so work efficiency and quality can be improved. Is possible.

  Preferably, the part change information is information indicating a change content made to the component indicated by the basic part information in a distribution process after the design stage of the product. As a result, even if the component set in the design stage is changed in each stage of the subsequent distribution process, the change content is stored as the part change information so that it can be appropriately managed on the database. be able to.

  In this case, the part change information may be obtained by associating the change contents of the component parts of the product with the distribution information specifying the stage where the change is made in the distribution process of the product. Thereby, it is possible to manage in time series what kind of component has been changed at which stage of the distribution stage.

  The database further includes a maintenance information database that stores maintenance information indicating information on maintenance performed on each of the plurality of products, and the processing unit includes maintenance information corresponding to the designated product. May be acquired and output together with the component list of the product. According to this, since the maintenance information such as the maintenance history performed in the past is output together with the change contents of the component parts for the specified product, the past handling history of the product can be managed in more detail. Improve operational efficiency and quality more effectively.

  The processing unit may extract a product in which the specified part is used from the plurality of products and output the product as a corresponding product list. According to this, a product in which a specific component is used can be extracted from many products under the management of this system. Therefore, for example, even when a recall occurs for a specific part, it is possible to quickly grasp a product in which the same part is used.

  In order to solve the above-described problem, the parts information management method according to the present invention manages each of a plurality of products by storing the component parts in a database so as to be readable, wherein the database is the product. For each type, a basic part information database that stores basic part information indicating component parts defined in the design stage, and part change information that indicates a change history of the component parts that has been performed for each of the plurality of products A second step of acquiring basic component information and component change information of a specified product from the basic component information database and the component change information database, comprising: a component change information database stored in association with component information; , Component parts of the designated product based on the acquired basic part information and part change information Characterized by comprising a third step of displaying on the output to the display unit as a component list.

  According to the component information management method of the present invention, the component information management system (including the various aspects described above) can be appropriately realized.

  According to the present invention, the basic part information and the part change information of the specified product are acquired from the basic part information database and the part change information database, and the component parts of the product are output as a component part list, thereby allowing the design stage. Even when the component set in step S1 is changed, accurate component parts can be managed for each individual product, so that it is possible to improve work efficiency and quality.

It is a schematic diagram which shows the arrangement | positioning at the time of a vibration test of the electric power generation system which uses the diesel engine which is an example of a management object product as a motive power source from the side surface side.

  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention unless otherwise specified, but are merely illustrative examples. Not too much.

  In the present specification, as an example of a parts information management system according to the present invention (hereinafter referred to as “the present system” as appropriate), a diesel engine used in a power plant is a product to be managed, and the design / manufacturing / An example will be described in which a product is delivered to a customer via a sales company (hereinafter referred to as “sales company” where appropriate) after shipment after inspection, and the product is used by the user at the delivery destination.

  FIG. 1 is a block diagram showing the overall configuration of the system 1. The system 1 is installed in a company (for example, a management department) of a manufacturer that is a product manufacturer, and includes a processing unit 2 for performing control, operation, various calculations, and the like of each component described below, Necessary for control, operation, calculation, etc. of the system 1, an input unit 3 for an operator of the system 1 to input various information, a display unit 4 that performs appropriate display on the display in response to an instruction from the processing unit 2 And a database 5 in which various kinds of information are stored.

  In the present embodiment, the processing unit 2, the input unit 3, the display unit 4, and the database 5 will be described on the premise that they are collectively installed on the site of the manufacturer. It may be configured to be able to communicate with each other through a communication line such as a line or a LAN line so that they can communicate with each other while being installed at geographically distant locations. In particular, the input unit 3 is not only an operator of the system 1 but also a portable terminal owned by a worker who performs maintenance work on the product installation site (delivery destination), or a fixed device installed at the product delivery destination. It may be configured such that various information can be transmitted from the input unit to the main body side including the processing unit 2 installed on the manufacturer side that is the management base via the communication line. .

  The database 5 stores various information necessary for the operation of the system 1. The database 5 is divided into an identification information database 5a, a basic component information database 5b, a component change information database 5c, and a maintenance information database 5d according to the type of stored information.

  Identification information for identifying an operator who can use the system 1 is stored in the identification information database 5a. The operators of the system 1 are, for example, a plurality of specific employees who belong to a specific department of the manufacturer (for example, a management department in charge of product management). This system 1 manages the component parts for each individual product, and includes information important for security for the manufacturer. The identification information stored in the identification information database 5a includes, for example, an ID and password required for logging in to the system 1 given to each operator, a range of access authority of each user, and an access history to the system 1. This is information for identifying and managing an operator who uses the system 1, such as an access error occurrence history.

  The basic part information database 5b stores basic part information indicating component parts defined in the design stage for each type of product. Note that the basic part information is information indicating the constituent parts before the change of the constituent parts in each stage after the design stage, as will be described later.

  FIG. 2 shows an example of basic component information stored in the basic component information database 5b. Such basic part information is prepared for each individual product specified by “model type” and “unit”, and lists the component parts defined in the design stage. In this example, items such as “reference number”, “part number”, “part name”, and “quantity” are defined as information for specifying each component.

  In the part change information database 5c, part change information indicating a change history of component parts performed for each of a plurality of products is stored in association with basic part information. In other words, the component change information is component information corresponding to the changed basic component information, and represents how the component has been changed at each stage of the distribution process inside and outside the manufacturer. .

  FIG. 3 is an example of component change information stored in the component change information database 5c. The component change information is the component part of the product specified by the model type / unit at each stage of the distribution process after the design stage (here, the manufacturing stage, the inspection stage, the shipping stage, the post-shipping stage, etc.). It is configured to be identifiable. In the part change information, the items such as “reference number”, “part number”, “part name”, and “quantity” are defined for each “model / model” and “unit” as in the basic part information described above. ing. Since the items for specifying the component parts in these part change information are associated with each other by using the same number and name as the basic part information, both are centrally managed in the processing unit 2 as described later. It is configured to be able to.

  In particular, in this embodiment, in the part change, a common reference number is assigned to a part common to basic part information, while a different reference number is assigned to a part changed from the basic component part. It is like that. Thus, it is defined that the changed component can be easily discriminated.

  The maintenance information database 5d stores maintenance information indicating information related to maintenance performed on each of the plurality of products. Specific examples of maintenance information include product results such as the results of regular or irregular inspections of products used at the delivery site, response history when malfunctions occur, construction history such as product upgrades, etc. There are maintenance details performed when an event related to component change occurs.

  In addition, the information stored in the database 5 may widely include information indicating the distribution history of products after the design stage. The product is designed by the designer in the manufacturer, manufactured according to the design, and the manufactured product is shipped after being inspected for quality confirmation and sold to the customer (in this example, In particular, they are sold through sales companies that act as sales agents.) For example, information indicating the distribution history of such a product within and outside the manufacturer may be included. Specifically, at each stage of design, manufacturing, and inspection within the manufacturer, there is a person in charge and an implementation period. In addition, at the stage after shipment outside the manufacturer, information for identifying the sales company that sold the product to the customer (for example, the sales company name, address, sales date, sales representative, etc.) Information to identify a customer (for example, the customer's company name, department, address, industry, etc.), information to identify the user who is actually using the product (customer ’s name, department, usage, etc.), Information for specifying a maintenance company in charge of maintenance may be included.

  Next, specific processing contents of the system 1 having the above-described configuration will be described. Hereinafter, “part information registration process” and “part information search process” will be sequentially described as main processing contents of the system 1.

(Part information registration process)
First, the component information registration process will be described with reference to FIG. In the part information registration process, when changes occur in the component parts of the product at each stage, the change status of the component parts of the product is managed by newly registering or updating the part change information stored in the part change database 5c. It is processing to do. FIG. 4 is an example of a display screen used for the component information registration process.

  When the component information registration process is performed, the component information registration screen 10 shown in FIG. The component information registration screen 10 displays a component list 13 of products corresponding to the model type / number entered by the operator at reference numerals 11 and 12. This component list 13 is created based on the basic component information stored in the basic component information database 5b and the component change information stored in the component change information database 5c. Are listed.

  The operator operates the input unit 3 to select a part to be changed from the component list 13, and rewrites the input unit 3 to each item that defines the part. Then, the operator clicks the “Register” button 14 to register the rewriting content in the part change information database 5c. Here, when there is no part change information corresponding to the product in the part change information database 5c (when there is no corresponding part change information because no part change has been performed in the past), the input information Is newly registered as part change information. On the other hand, when the part change information corresponding to the product already exists in the part change information database 5c, the input information is reflected by updating the part change information.

  When the part change information is updated, the part change information before the update may be stored as history data so that it can be traced as a history. This makes it possible to provide a higher quality service by referring to past history data later for maintenance or the like.

  This registration update operation can be performed in any of a series of product distribution processes such as a design stage, a manufacturing stage, an inspection stage, a shipping stage, and a user stage. Therefore, when the component information is changed at each stage, the latest component information can be reflected in the registration contents of the database 5 by sequentially performing the registration update operation. As a result, accurate component parts can be managed for each individual product, so that it is possible to improve work efficiency and quality.

(Part information search processing)
Next, the component information search process will be described with reference to FIG. In the part information search process, the database 5 is searched according to the search condition input by the operator, and the search result is displayed, whereby the component parts of the product can be grasped. FIG. 5 is an example of a display screen used for the component information search process.

  When the component information search process is performed, the component information search screen 20 shown in FIG. In the example of FIG. 5, “model / model search” and “user search” are displayed as search methods on the part information search screen 20. Here, “Model / Unit Search” and “User Search” are displayed as search methods, but instead of or in addition, based on various information such as “Customer Name”, “Sales Company Name”, “Maintenance Company Name”, etc. May be configured to be searchable.

  In “model type / unit search”, when the operator inputs a model type and a unit as a search condition from the input unit 3 in the input fields indicated by reference numerals 21 and 22, the search unit 23 is clicked. Gets its input. Then, the processing unit 2 accesses the database 5, obtains information (basic part information, part change information, maintenance information, etc.) corresponding to the inputted “model type” and “unit”, and displays the search result on the screen. (For display results, see FIGS. 6 to 8 described later). Similarly, in the “user search”, after the user name as the search condition is input from the input unit 3 to the input field indicated by reference numeral 24 by the operator, the search is executed by clicking the search button 25. At this time, if there are a plurality of engines corresponding to the search condition, these engines may be output as a list in a list format and displayed so that the operator can select them. In this case, in order to make it easier for the operator to select the intended engine, in addition to “model type” and “unit”, information related to the engine that meets the search conditions, such as “customer name” and “user name” is displayed in a list. Good.

  The operator operates the input unit 3 such as a mouse or a keyboard for the display, and selects an intended product from the list. Then, the processing unit 2 acquires basic part information and part change information corresponding to the selected product by accessing the third database 5c and the fourth database 5d. Then, based on the acquired basic part information and part change information, the latest component parts actually used in the product at present are displayed on the display unit 4 as a list.

  FIG. 6 is an example of a list of engine components displayed on the display unit 4 in this way. In this example, a list of engine component parts is configured in the order of the part number assigned to each part. Each part is given a part name, a group number, a group name, and a quantity, and based on this, the user can confirm the constituent parts.

  In this example, the components are listed in the order of the part numbers. However, if necessary, the user convenience may be improved by sorting by other items (group classification, reference number, etc.).

  FIG. 7 shows another example of the list of engine component parts. First, FIG. 7A shows group classifications in large categories such as the engine main body, intake / exhaust system, and lubrication system, and by selecting each, the list is shifted to a more detailed list shown in FIG. 7B. It is configured as follows. It should be noted that such a list of component parts may be displayed together with a corresponding drawing so that a user-intended part can be easily recognized visually.

  Returning to FIG. 6 again, a link for accessing maintenance information stored in the maintenance information database 5d may be provided in the list of component parts displayed in this way. The operator can acquire maintenance information (for example, maintenance company name, inspection result, repair history, construction history, update history, etc.) corresponding to the product from the link. For this reason, it is possible to grasp how the changes in the component parts displayed in the list are made, so that the efficiency and quality of the service can be improved.

  Other specific examples of such maintenance information include product operation records, measurement data (monitored data if 24-hour remote monitoring is performed), troubleshooting history (technical contact) And construction request forms, yellow sheets, etc.). As described above, the maintenance information stored in the fifth database 5e is integrated and managed in association with another database through a link, so that the quality of service can be improved comprehensively.

  Another example of the part information search process is a part number search. In “part number search”, the display unit 3 displays the part number search screen 30. Here, FIG. 8 shows an example of the part number search screen 30. As shown in FIG. 8, in the part number search screen 30, when an operator inputs a part number in an input field 31 as a search condition and clicks a search button 32, a part corresponding to the input part number is used. The displayed product list 33 can be displayed.

  In this way, in the part search process, products can be extracted on the basis of parts, so that a quick response is possible when a recall of a specific part occurs. As a result, other machines in which similar parts are used can be identified by searching the database, and measures for preventing the occurrence of defects can be implemented in advance.

  In the above description, the input unit of the system 1 is installed at the jurisdiction base in the manufacturer and has been described assuming that the operator in charge of the operation operates. However, those who are involved in each stage of the product distribution process May be configured to be operable as an operator using a predetermined terminal. As a result, it is possible to share the change information of the component parts among those who are involved in the distribution of products, so that the business efficiency of each department can be improved.

  Here, as an example of improving business efficiency in other departments using the present system 1, an example applied to correction of a determination threshold value in a pre-shipment inspection of a product according to a change in a component will be specifically described. In this example, in particular, as an example of pre-shipment inspection, frequency analysis is performed on the time history data of the operating state of the power generation system that uses a diesel engine that is a managed product as a power source, and the remaining components of the major hours are expressed as threshold values. A vibration test for evaluating the pass / fail judgment will be described.

  FIG. 9 is a schematic diagram showing the arrangement of the power generation system 100 that uses a diesel engine, which is an example of a management target product, as a power source during a vibration test from the side surface side. In the power generation system 100, a diesel engine 102 serving as a power source that is a management target product and a generator 103 connected to an output shaft of the diesel engine 102 are installed on a common base plate 101. In the quality assurance department having jurisdiction over the inspection stage, a vibration test is performed by moving the power generation system 100 installed in this manner, and the presence or absence of an operational abnormality is determined. In this vibration test, reference numerals 110a (upper front of the common base plate 101), 110b (lower front of the common base plate 101), 110c (upper center of the common base plate 101), 110d (center of the common base plate 101) in FIG. (Lower part), 110e (upper rear part of common base plate 101), 110f (lower rear part of common base plate 101), 110g (upper part of diesel engine 102), 110h (generator 103), 110i (bearing part of generator 103) A vibration sensor is installed at each position indicated by, and the time history data of the displacement amount detected by each vibration sensor is subjected to frequency analysis, and whether or not the remaining major time component is greater than a preset threshold value. Based on this, the presence or absence of abnormality is determined.

  Basically, the threshold value for determining whether or not the vibration test is successful is set based on specifications defined in the design stage, that is, basic component information. However, as described above, when a component is changed in the previous stage of the inspection stage, for example, in the design stage or the manufacturing stage, the threshold value for determining the pass / fail of the vibration test is also changed according to the change contents of the component part. It should be. Conventionally, such changes in the component parts in the previous stage are not reflected in the threshold value, and it has not been possible to accurately evaluate the operating state of the product.

  On the other hand, in the present invention, since the change contents of the component parts can be grasped by referring to the part change information as described above, by correcting the threshold according to the change contents, The evaluation accuracy can be improved and the business condition can be improved. More preferably, correction values corresponding to the component parts before and after the change are stored in advance in the database 5 as a map, and from the map according to the content of the part change information acquired by the processing unit 2 from the part change information database 5c. It is preferable that the threshold value is automatically corrected by reading the correction value.

  Note that such a business improvement example is merely an example in the inspection stage, and it goes without saying that the business improvement can be applied to each stage in and outside the manufacturer.

  As described above, by acquiring the basic part information and part change information of the designated product from the basic part information database 5b and the part change information database 5c, and outputting the component parts of the product as a component part list, Even when changes have been made to the components set at the design stage, accurate component components can be managed for each individual product, thus improving operational efficiency and quality. .

  The present invention is applicable to a component information management system and a component information management method for managing each of a plurality of products by storing component parts in a database so as to be readable.
