  In FIG. 1, a maintenance information management system 10 embodying the present invention manages and provides maintenance information collected for equipment, for example, manufacturing equipment, in an easy-to-use form. The maintenance information management system 10 includes a terminal device 11 and a server device 12.

  The terminal device 11 is a general computer including a display unit 14 configured by a liquid crystal display or the like and an operation unit 15 configured by a keyboard, a mouse, and the like, and a maintenance information management system 10 by executing a predetermined program. Act as part of The terminal device 11 is connected to the server device 12 via a LAN (Local Area Network) or the like, and various maintenance information is input to the maintenance information management system 10 by operation of the operation unit 15 and displayed on the display unit 14. A plurality of terminal devices 11 can be connected to the server device 12 for use.

  The server device 12 is configured by a general computer including a CPU, a memory, a hard disk drive, a communication interface circuit, and the like. By executing the maintenance information management program, the server device 12 performs maintenance database (DB) 16, maintenance note registration unit 17, accompanying maintenance information recording unit 18, correction unit 19, equipment specification database 21, daily inspection database 22, screen It functions as a generation unit 23, an information acquisition unit 24, a reverse lookup unit 25, and the like. In the maintenance database 16, a maintenance note W (see FIG. 3) in which maintenance information is recorded is registered. In addition, the maintenance database 16 is a hierarchical information storage unit that stores hierarchical information indicating the hierarchical structure of the management units described later, that is, the upper / lower relationship of the management units. Although the hierarchy information is stored in the maintenance database 16, a hierarchy information storage unit that stores the hierarchy information may be provided separately from the maintenance database 16.

  The maintenance information management system 10 manages the maintenance information for each management unit by creating a hierarchical structure in which the configuration of equipment to be maintained is hierarchically classified into a plurality of management units. For example, each component constituting the device is set as a management unit, and the equipment configuration is hierarchically classified (hierarchized) so that the device constituted by these components becomes a higher management unit of each component. This classification can be performed from an arbitrary viewpoint as long as the relationship between the upper and lower management units is clear. In addition to the viewpoint of classifying as an object such as an apparatus or a part as described above, classification can be performed from various viewpoints such as each process, each processing content, and each group having the same function.

  One management unit is associated with one maintenance note W. In this example, the maintenance information recorded in the maintenance note W includes inspection information, failure information, maintenance instruction information, maintenance result information, analysis information, and failure report information. Such maintenance information is classified into basic maintenance information and incidental maintenance information. As shown in FIG. 2, the maintenance note W is a collection of basic maintenance information and additional maintenance information related to the basic maintenance information as a group of information. For basic maintenance information, incidental maintenance information is recorded as necessary.

  The basic maintenance information is information on an event that triggers registration of the maintenance note W, and is input when a new maintenance note W is registered. On the other hand, the accompanying maintenance information is information derived from the event of the basic maintenance information, and is preferably information that is attached to the basic maintenance information as a series of information. One maintenance note W is registered in the maintenance database 16 for one basic maintenance information. Each additional maintenance information is recorded in the maintenance note W in which basic maintenance information to be added is recorded.

  In this example, failure information, inspection information, and maintenance instruction information are used as basic maintenance information. When failure information is used as basic maintenance information, analysis information analyzing the cause of the failure, maintenance instruction information for instructing maintenance based on the failure information and analysis information, and results of maintenance performed based on the maintenance instruction information The information and the final failure report information become supplementary maintenance information. In addition, when the inspection information is used as basic maintenance information, the analysis information that analyzes the cause of the abnormality indicated in the inspection information, the maintenance instruction information that instructs maintenance based on the inspection information and the analysis information, and the maintenance instruction information The maintenance result information of maintenance carried out in this way is supplementary maintenance information.

  The maintenance instruction information can be basic maintenance information or incidental maintenance information as described above. When the maintenance instruction information is the basic maintenance information, the maintenance result information of the maintenance performed based on the maintenance instruction information becomes the additional maintenance information. In the following, when it is necessary to distinguish between maintenance instruction information as basic maintenance information and maintenance instruction information as auxiliary maintenance information, the former will be referred to as basic maintenance instruction information and the latter as auxiliary maintenance instruction information. To do.

  As shown in FIG. 3, each maintenance information includes the type of the maintenance information. As shown in FIG. 3A, the failure information includes a failure occurrence date, a failure status indicating a specific content of the failure, a measure corresponding to the failure, and the like. The inspection information is recorded when an abnormality that does not lead to a failure is found during periodic inspection. As this inspection information, as shown in FIG. 3B, there are an abnormality occurrence date, an abnormal situation indicating the content of the abnormality that has occurred, a treatment corresponding to the abnormality, and the like. Note that the inspection information may be recorded even if the periodic inspection results are normal or when there is no particular problem. In this case, all the inspection information may be displayed in the history, and it is preferable that only the inspection information in which the abnormality is recorded among the inspection information can be displayed in the history.

  The maintenance instruction information is recorded when an instruction to perform maintenance is given. As shown in FIG. 3C, the maintenance instruction information includes a scheduled maintenance date, maintenance contents, maintenance specifications indicating maintenance procedures, replacement part numbers, costs, and the like. The maintenance result information records the maintenance contents when the maintenance is performed. As shown in FIG. 3D, the maintenance date, the specific contents of the maintenance performed, the state of the replaced parts, There are maintenance statuses, etc., indicating the status after maintenance. As shown in FIG. 3 (e), the analysis information includes an analysis date, an analysis result obtained by analyzing the cause of the failure or abnormality, a material used for the analysis, and the like. As shown in Fig. 3 (f), the failure report information includes the report date when the failure report information was input, the damage caused by the failure, the cause of the failure and the permanent measures to prevent the failure (cause and measures), etc. There are various reports such as requests to departments.

  The title and specific location are further recorded in the failure information, inspection information, and maintenance instruction information recorded as basic maintenance information. The title is input from the operation unit 15 as information that directly indicates a failure, abnormality, maintenance content, or the like. The specific location is a management unit in which a failure or an abnormality has occurred, or a management unit that is a maintenance target. The maintenance note registration unit is automatically set according to the linking destination of the specified maintenance note W as described later. 17 is recorded.

  Note that the title and specific location recorded in the basic maintenance information are common to the maintenance note W and each additional maintenance information recorded therein, and are also information on the additional maintenance information. Of course, the same title and specific location as the basic maintenance information may be recorded as a part of the additional maintenance information.

  Further, the title and the specific place may be recorded in the maintenance note W as maintenance information different from the inspection information. Which maintenance information is to be added to the basic maintenance information can be changed as appropriate. For example, when it can be determined that a substantial failure has occurred after maintenance, failure report information may be recorded as additional maintenance information of inspection information or maintenance instruction information. In this example, the maintenance instruction information in the case where maintenance is instructed based on failure information and inspection information is used as additional maintenance information. However, the maintenance instruction information may be used as basic maintenance information.

  Furthermore, as long as the maintenance note W can handle the basic maintenance information and each additional maintenance information as a group, any recording mode of each information on the maintenance database 16 may be used. For example, each information field of basic maintenance information and incidental maintenance information to be recorded in one maintenance note W may be provided and recorded in one record. In addition, the basic maintenance information and each additional maintenance information are recorded in separate records, and the ID of the record in which the basic maintenance information is recorded is recorded in each additional maintenance information record. It can also be treated as information.

  Clicking and selecting the operation unit 15 with the mouse, inputting characters on the keyboard, etc., generating a new maintenance note W, inputting and correcting the title of the maintenance note W, inputting maintenance information, specifying and selecting a management unit Specified / corrected specific location, history display, maintenance information display instruction, etc. The operation unit 15 and the display unit 14 constitute a graphical user interface, and various inputs, instructions, selections, and the like can be performed through the graphical user interface.

  Note that the instruction to newly generate the maintenance note W, the input of various maintenance information, the designation and selection of the management unit, etc. are not limited to the operation of the operation unit. For example, a maintenance management server that manages a maintenance plan automatically inputs a command for generating a new maintenance note W, maintenance instruction information, and a management unit to be maintained into the server device 12 based on the maintenance plan (schedule). The device 12 may register a new maintenance note W in which maintenance instruction information is recorded as basic maintenance information in association with a management unit to be maintained in the maintenance database 16.

  When a new maintenance note W is generated, a management unit to which the maintenance note W to be generated, that is, a specific location, and a type of basic maintenance information to be recorded are respectively designated by operating the operation unit 15 and the maintenance note W is recorded. Instructs the new generation of. The maintenance note registration unit 17 generates a new maintenance note W corresponding to the type of the designated basic maintenance information in response to a new generation instruction. Further, after the maintenance note W is generated, the maintenance note registration unit 17 records the basic maintenance information input from the operation unit 15 in a new maintenance note W, and associates the maintenance note W with the designated management unit. Register in the maintenance database 16. At this time, the designated management location is added to the basic maintenance information as a specific location. When associating the maintenance note W with the management unit, for example, the management unit ID given in advance to the management unit to be associated with the record in which the basic maintenance information is recorded may be recorded. The management unit of the specific location of the basic maintenance information matches the management unit of the linked destination.

  When the incidental maintenance information is recorded in the maintenance note W, the maintenance note W to be recorded is designated by the operation of the operation unit 15 and the incidental maintenance information is input. The accompanying maintenance information recording unit 18 specifies the designated maintenance note W among the maintenance notes W registered in the maintenance database 16, and records the accompanying maintenance information in the specified maintenance note W.

  The correction unit 19 corrects the management unit (specific location) to which the maintenance note W is linked according to the operation of the operation unit 15. The correction operation is performed by designating a new management unit using the operation unit 15. In response to this correction operation, the correction unit 19 sets, for example, the management unit ID assigned to the record in which the basic maintenance information is recorded as the management unit ID of the specified new management unit. Accordingly, the specific location can be moved to a lower management unit so as to allow provisional input of the specific location and to narrow down the specific location sequentially. The title is also corrected by the correction unit 19 in accordance with the operation of the operation unit 15.

  The equipment specification database 21 stores information such as specifications and drawings (hereinafter referred to as equipment information) from the entire equipment to individual parts. This facility information is classified hierarchically and associated with the corresponding management unit in the same manner as the facility to be maintained. Thereby, for example, when performing analysis or maintenance instruction, it is easy to refer to the designated management unit and the equipment information below it.

  The daily inspection database 22 collects and stores measurement data of each device constituting the facility. The measurement data is obtained by measuring the temperature, vibration magnitude, voltage, etc. of the device. For example, measurement of temperature, magnitude of vibration, voltage, etc. is performed at a predetermined time every day by a sensor unit provided in each device to be measured. During the patrol of the inspector, the data collector 31 carried by the inspector sequentially receives the measurement data from each sensor unit, thereby collecting the measurement data. The data collector 31 is connected to the terminal device 11 after patrol. The collected measurement data is stored in the daily inspection database 22 from the terminal device 11 via the I / F unit 32 of the terminal device 11. When storing the measurement data, the I / F unit 32 associates the management unit with a management unit ID corresponding to the measurement target device. Thereby, for example, when performing analysis, it is easy to refer to the designated management unit and measurement data below it.

  The screen generation unit 23 generates various screens based on the information acquired by the information acquisition unit 24 and the information acquired by the reverse lookup unit 25 and displays them on the display unit 14. In addition, when generating a new maintenance note W, the screen generation unit 23 generates a screen for inputting basic maintenance information to the new maintenance note W. The information acquisition unit 24 acquires various types of information from the maintenance database 16, the equipment specification database 21, and the daily inspection database 22 based on the operation of the operation unit 15, and sends it to the screen generation unit 23.

  The reverse lookup unit 25 includes a reverse lookup database (not shown) in which failure contents and abnormality contents are associated with causes thereof. The reverse lookup unit 25 searches the reverse lookup database for the cause corresponding to the failure or abnormality input by the operation unit 15, and sends the cause identified by this search to the screen generation unit 23 as a cause candidate. Thereby, the cause candidate corresponding to the failure content or the abnormality content is displayed on the display unit 14.

  FIG. 4 shows an example of a hierarchical structure of management units. In this example, the management unit “A factory” is the highest level, and the management units “inspection equipment” and “film forming equipment” are in the lower hierarchy of the management unit “A factory”. An example of a specific film forming facility corresponding to the management unit “film forming facility” is shown in FIG. The film forming equipment 40 has a film forming area 42 for forming a film having a predetermined function on a long film 41 and a drying area 43 for drying the formed film on one manufacturing line. A winding device 44 for winding the film 41 is disposed at the end of the line. In the lower hierarchy of the management unit “film forming equipment”, there are management units “film formation area”, “drying area”, and “winding device” corresponding to the areas 42 and 43 and the winding device 44. Management units with different classification categories such as “area” and “device” may be in the same hierarchy.

  In the drying area 43, there are a transport device 45 that transports the film 41 and a drying device 46 that performs film drying. ”And“ Drying equipment ”. The transport device 45 is provided with a drive system 47 and a first pass roll 48a, a second pass roll 48b, a third pass roll 48c,... For guiding the film 41 in the drying device 46. The drive system 47 includes a transport motor 47a, a transport roller 47b that is rotated by the transport motor 47a and transports the film 41, and a drive circuit 47c that drives the transport motor 47a.

  Regarding the drive system 47, a management unit “drive system” is provided in a lower hierarchy of the management unit “conveyance device”, and a management unit “conveyance motor” is provided under the management unit “drive system”. A “conveyance roller” and a “drive circuit” are provided. For the first pass roll 48a, the second pass roll 48b, the third pass roll 48c,..., A management unit “pass roll group” of groups having the same function is provided below the management unit “transport device”. Management units “first path role”, “second path role”,... Are set below the management unit “path role group”. For example, when the pass roll can be disassembled into roller parts, shaft parts, and bearing parts, the management unit of these parts may be set below the management unit of the pass roller. Of course, in order to reduce the complexity of management due to such subdivision, the management unit need not be subdivided.

  On the other hand, the drying device 46 is subordinate to the management unit “drying device” corresponding to the air supply unit 51, the chamber 52, and the blower fan 53 and the blower drive circuit 54 constituting the air supply unit 51. The management units “air supply unit” and “chamber” are provided, and the management units “air blowing fan” and “air blowing drive circuit” are provided below the management unit “air supply unit”. Further, management units “blade” and “blower fan” are set below the management unit “fan” corresponding to the blades 53 a and the fan motor 53 b constituting the fan 53.

  Note that the lower management unit of any one management unit is each management unit that is higher than the one management unit, and the depth of the hierarchy from the highest management unit as a base point is the one management unit. It does not mean a management unit deeper than the management unit. For example, the lower management units of the management unit “drying device” are “air supply unit”, “chamber”, “blower fan”, “drive circuit for blower”, “blade”, “blower motor”. The management units “pass roll group” and “drive unit” subordinate to the “transport apparatus” and the management units subordinate to these are not subordinate management units of the “drying device”.

  The display unit 14 displays a first history window G1 (see FIG. 6), a second history window G2 (see FIG. 7), and a note window G3 (see FIG. 9). A plurality of windows G1 to G3 may be displayed at the same time, or may be switched and displayed.

  As shown in FIG. 6, a first hierarchy screen G1a and a first history screen G1b are displayed in the first history window G1. The first hierarchy screen G1a shows a hierarchical structure of management units, and a hierarchical structure diagram D similar to that shown in FIG. 4 is displayed. In order to display the first hierarchy screen G1a, the information acquisition unit 24 acquires hierarchy information from the maintenance database 16. Based on this hierarchical information, the screen generator 23 generates a first hierarchical screen G1a including the hierarchical structure diagram D.

  The hierarchical structure diagram D on the first hierarchy screen G1a can be displayed in a state where a lower layer of an arbitrary management unit is expanded or displayed in a state where the expansion is canceled by the operation of the operation unit 15. . This makes it possible to efficiently refer to the required management unit and its upper and lower hierarchies.

  The first history screen G1b shows the maintenance status relating to the management unit selected in the hierarchical structure diagram D and the management units below this management unit. In order to display the first history screen G1b, the information acquisition unit 24 specifies a lower management unit of the management unit selected in the hierarchical structure diagram D based on the hierarchy information, and selects the selected management unit. The maintenance information recorded in the maintenance note W linked to the management note W and the maintenance note W linked to the specified management unit are respectively acquired and sent to the screen generation unit 23.

  The screen generation unit 23 sets the date, specific location, title, and type extracted from the basic maintenance information among the maintenance information input from the information acquisition unit 24 as the note information R1. This note information R1 is generated for each maintenance note W from which maintenance information has been acquired. If the basic maintenance information is failure information or inspection information, the failure occurrence date and the abnormality occurrence date are taken out as dates. If the basic maintenance information is maintenance instruction information and maintenance result information is not recorded, the scheduled maintenance date is extracted, and if maintenance result information is recorded, the maintenance execution date is extracted as the date.

  When the type is “maintenance result”, the screen generation unit 23 converts the type into “maintenance” indicating that the type has been maintained, and when the type is “maintenance instruction”, the screen generation unit 23 indicates that the type is “maintenance planned”. (Scheduled) "and used.

  The note information R1 acquired from the basic maintenance information as described above is the first note information based on the basic maintenance information. Note that the “maintenance instruction” and “maintenance result” acquired without converting the type into “maintenance (planned)” or “maintenance” may be displayed.

  Further, in this example, when the basic maintenance information is failure information and inspection information, and the accompanying maintenance instruction information is recorded in the maintenance note W, the screen generator 23 uses the notebook information R1 based on the basic maintenance information. Separately, the notebook information R1 based on the accompanying maintenance instruction information or the maintenance result information is generated. When the accompanying maintenance instruction information and the maintenance result are recorded, the screen generating unit 23 extracts the date of the notebook information R1, the maintenance execution date and the maintenance status as the title, and the “maintenance result” as “maintenance” as the type. Convert to and use. Further, as the specific location of the note information R1, the specific location recorded in the basic maintenance information is used. The notebook information R1 based on the maintenance result information is the second notebook information.

  When the accompanying maintenance instruction information is recorded but the maintenance result information is not recorded, the screen generation unit 23 extracts the date of the notebook information R1, the scheduled maintenance date as the title, and the maintenance content. “Instruction” is converted to “Maintenance (planned)”. Further, as the specific location of the note information R1, the specific location recorded in the basic maintenance information is used. The notebook information R1 based on the maintenance instruction information is the third notebook information.

  The screen generation unit 23 generates a first history screen G1b in which each piece of note information R1 acquired by the information acquisition unit 24 is arranged in time series, and displays the first history screen G1b on the display unit 14. The reference date when arranging in time series is the date taken out as a part of the note information R1.

  As shown in FIG. 7, a second hierarchy screen G2a and a second history screen G2b are displayed in the second history window G2. The second hierarchy screen G2a shows the hierarchical structure diagram D as with the first hierarchy screen G1a. The second history screen G2b shows the maintenance status regarding the management unit selected in the hierarchical structure diagram D on the second hierarchy screen G2a and each management unit subordinate to this management unit. This is different from the one history screen G1b.

  As shown in FIG. 8, the second history screen G2b is arranged in time series in a state in which the respective notebook information R2 is classified into types of failure, inspection, and maintenance. In order to display the second history screen G2b, the information acquisition unit 24, as in the case of the first history screen G1b, the maintenance note W linked to the management unit selected in the hierarchical structure diagram D, The maintenance information recorded in the maintenance note W associated with the lower management unit of the management unit is acquired and sent to the screen generation unit 23.

  The screen generation unit 23 sets the title of the basic maintenance information as the note information R2 when displaying the second history screen G2b. Therefore, the title included in the basic maintenance information among the maintenance information input from the information acquisition unit 24 is set as the note information R2. This note information R2 is generated for each maintenance note W from which maintenance information has been acquired. In addition, when the basic maintenance information is failure information or inspection information, the screen generator 23 generates note information R2 based on the accompanying maintenance instruction information or maintenance result information separately from the note information R2 based on the basic maintenance information. To do. When the accompanying maintenance instruction information and the maintenance result are recorded, the screen generation unit 23 sets the maintenance status as the note information R2, and when the maintenance instruction information is recorded but the maintenance result information is not recorded. In this case, note information R2 is obtained by adding “(planned)” to the maintenance content.

  As for the note information R2 when the second history screen G2b is displayed, the first note information is based on the basic maintenance information, and the note information R2 based on the maintenance result information is the second note information and the maintenance instruction information. Note information R2 based on is the third note information.

  The screen generation unit 23 generates the second history screen G2b by arranging the notebook information R2 generated as described above in time series based on the date in the state classified as maintenance, inspection, and failure. The date used as a reference when arranging in time series is based on the basic maintenance information of the notebook information R2, and when the basic maintenance information is failure information or inspection information, it is a failure occurrence date and an abnormality occurrence date. The notebook information R2 based on the basic maintenance instruction information or the accompanying maintenance instruction information is a date based on the scheduled maintenance date, and the notebook information R2 based on the maintenance result information is a date based on the maintenance execution date.

  When note information R2 is based on failure information or inspection information, it is classified as failure or inspection, and note information R2 is based on basic maintenance instruction information, accompanying maintenance instruction information, or maintenance result information. Is classified as maintenance.

  Note that the information displayed as the note information R1, R2 is not limited to the above. For example, a maintenance title common to maintenance instruction information and maintenance result information may be recorded, and the title may be used as note information R2.

  The notebook window G3 is a window for editing and browsing maintenance information input to the maintenance note W and recorded in the maintenance note W. This note window G3 is displayed by a new generation instruction of the maintenance note W and a display instruction of the maintenance note W.

  The new generation instruction is, for example, new for each type of inspection, failure, or maintenance displayed on the display unit 14 in a state where an arbitrary management unit in the hierarchical structure diagram D on the hierarchical screen G1a or G2a is selected (designated). This is done by clicking a generation button (not shown). As a result, the selected management unit is designated as the link destination of the new maintenance note, and the type of basic maintenance information is designated. When viewing and editing information on the maintenance note W that has already been registered, one of the note information R1 and R2 displayed on the first history screen G1b or G2b is selected, and the display of the maintenance note W is displayed. Instruct. Thereby, the information of the selected maintenance note W is displayed in the note window G3.

  As shown in FIG. 9, the note window G3 has a history display area for displaying the third history screen G3a and an information display area for displaying the maintenance information recorded in the maintenance note W. Each button 56a to 56e is displayed in the note window G3.

This maintenance screen G3e includes maintenance contents as maintenance instruction information, maintenance specifications, costs, scheduled maintenance date and maintenance result information in addition to the type, title, specific location, and date of occurrence recorded in the basic information. The implementation date and maintenance status are displayed. When the maintenance instruction information is basic maintenance information, the main screen G3b having the same display content as the maintenance screen G3e is displayed.

  When the basic maintenance information is failure information, it is possible to click the failure button 56e. By clicking the failure button 56e, a failure report screen G3f for inputting and displaying failure report information is displayed as shown in FIG. In addition to the type, title, specific location, and date of occurrence recorded in the basic information, the failure report screen G3f displays the report date, damage, cause and countermeasure of the failure, and requested items.

  In the third history screen G3a, the title of each maintenance note W linked to the management unit to which the maintenance note W displaying information in the information display area is linked, and the lower management unit of the management unit, Dates are displayed in chronological order. The processing by the information acquisition unit 24 and the screen generation unit 23 when displaying the third history screen G3a is the same as when displaying the first history screen G1a except that the specific location and type are not displayed.

  In addition, you may enable it to select the classification of the maintenance information displayed on each log | history screen G1b, G2b, G3a.

  Next, the operation of the maintenance information management system configured as described above will be described. For example, a new maintenance note W is generated when a failure occurs in any of the facilities or when an abnormality is found by periodic inspection or when a maintenance instruction determined in the maintenance plan is input. The inspector is a management unit in which the occurrence of a failure or abnormality can be specified at that time on the hierarchical structure diagram D of the first hierarchy screen G1a of the first history window G1 or the second hierarchy screen G2a of the second history window G2. Or, select the management unit to be maintained.

  Subsequently, a new generation button of any type of inspection, breakdown, or maintenance is clicked. As a result, the maintenance note registration unit 17 is instructed to newly generate the maintenance note W with the selected management unit as the link destination and the inspection information, the failure information, or the maintenance instruction information as the basic maintenance information.

  Hereinafter, the periodic inspection will be described assuming that abnormal noise is generated in the drying area 43 of the film forming equipment 40 shown in FIG. If the location where the abnormal noise is generated cannot be specified more than in the drying area 43, the inspector selects the management unit “drying area” corresponding to the drying area 43 on the hierarchical structure diagram D, and checks it. Click on the Create New button. By this operation, the maintenance note registration unit 17 generates a new maintenance note W having the basic maintenance information type “inspection” and the specific place as the management unit “dry area”. Thereafter, the main screen G3b based on the generated new maintenance note W is generated in the screen generation unit 23, and the note window G3 is displayed on the display unit 14.

  Further, based on the hierarchical information stored in the maintenance database 16, the information acquisition unit 24 specifies a management unit under the management unit “dry area” as a specific place. Subsequently, the maintenance information recorded in the maintenance note W associated with the selected management unit “dry area” and the maintenance note W associated with the specified management unit is the information acquisition unit. 24 from the maintenance database 16. The acquired maintenance information is sent to the screen generator 23, whereby a third history screen G3a is generated and displayed in the note window G3.

  Therefore, in addition to the management unit “drying area”, the third history screen G3a includes the management units “transport device”, “pass roll group”, “drive system”, “first pass roll”, “second pass roll”, “ 3rd pass roll "...," Drying device "," Air supply unit "," Chamber "," Blower fan "," Blower drive circuit "," Blade "," Blower motor " A failure occurrence date, an abnormality occurrence date, a scheduled maintenance date or a maintenance execution date obtained from each maintenance note W, and a title, maintenance content or maintenance status are displayed in a time series.

  The inspector operates the operation unit 15 to input the title, date (abnormality occurrence date), abnormal condition, and treatment on the main screen G3b. Thereafter, the maintenance note W in which the inspection information is recorded is registered in the maintenance database 16 by closing the note window G3 or clicking a registration button (not shown). In this registration, the maintenance note registration unit 17 records, for example, the management unit ID of the selected management unit “dry area” in the maintenance note W, thereby associating the maintenance note W with the management unit “dry area”. Note that basic maintenance information such as inspection information may be recorded in the maintenance note W after a new maintenance note W is once registered in the maintenance database 16.

  The inspector asks the analyst to analyze the cause as necessary. The requested analyst selects the note information R1 or R2 corresponding to the requested maintenance note W on the first history screen G1b of the first history window G1 or the second history screen G2b of the second history window G2. In the selected state, the display of the maintenance note W is instructed. In response to this instruction, the information acquisition unit 24 acquires the maintenance information recorded in the selected maintenance note W.

  In addition, the maintenance note recorded in each maintenance note W having the management unit “dry area” to which the maintenance note W is linked and each management unit lower than the management unit “dry area” as the link destination. Information is acquired from the maintenance database 16 by the information acquisition unit 24.

  As described above, the screen generation unit 23 generates the third history screen G3a and the main screen G3b based on the maintenance information acquired by the information acquisition unit 24, and the note window G3 including these screens G3a and G3b is displayed. At this time, inspection information input by the inspector is displayed on the main screen G3b. In addition, the third history screen G3a includes a management unit “dry area” and a failure occurrence date and an abnormality that are acquired from each maintenance note W that is associated with a management unit lower than the management unit “dry area”. The date of occurrence, the scheduled maintenance date or the maintenance implementation date, and the title, maintenance content or maintenance status are displayed in chronological order.

  When the reverse button 56b is clicked while the main screen G3b is displayed as described above, the reverse screen G3c is displayed in the information display area in the maintenance note window G3. A symptom, place, etc. are entered as keywords in the keyword field on the reverse screen G3c, and then the search button 57 is clicked. As a result, the reverse lookup unit 25 searches the reverse lookup database for the cause corresponding to the symptom and location entered in the keyword field. The searched cause is sent to the screen generation unit 23 and displayed as a cause candidate in the search result column on the reverse lookup screen G3c.

  The analyst accesses the equipment specification database 21 and examines parts, devices, and the like corresponding to the cause candidates. In addition, the daily inspection database 22 is accessed to check whether there is an abnormality in the measurement data, and further, the place where the abnormality occurs is specified by checking the site visually. At this time, when a specification reference button and a measurement data reference button (both not shown) displayed on the display unit 14 are clicked, the management unit associated with the maintenance note W displaying the current information and Equipment specifications and measurement data of a management unit under the management unit are displayed, for example, in a separate window. Thereby, equipment specifications and measurement data can be referred to quickly.

  When the analysis button 56c is clicked, an analysis screen G3d is displayed in the information display area in the note window G3. The analyst operates the operation unit 15 to input the cause of the abnormality in the analysis result on the analysis screen G3d. Also, material information such as measurement data and photographs acquired during analysis is entered in the material column. The analysis information input in this way is sent to the maintenance database 16 by the accompanying maintenance information recording unit 18 and recorded as analysis information of the maintenance note W being displayed.

  By the way, if the management unit in which an abnormality has occurred can be specified as described above, for example, the management unit indicated at the specific location in the analysis screen G3d is changed to the specified management unit by operating the operation unit 15. Correct it. For example, if it is possible to specify that an abnormal sound has occurred in the second pass roll 48b, the specific location that has been set as the management unit “dry area” until then is changed to the “second pass roll” that is a lower management unit. Correct it. In addition, you may correct on screens other than analysis screen G3d, for example, main screen G3b, reverse lookup screen G3c, maintenance screen G3e, etc.

  At the same time, the title will be modified to an appropriate one. For example, a title that was “abnormal noise generation in the dry area” is corrected to “second pass roll noise generation”. These correction contents are sent to the correction unit 19. As a result, the title of the maintenance note W whose information is currently displayed on the display unit 14 is corrected to “second path roll noise”, and the association destination of the maintenance note W is the management unit “second pass roll”. To be corrected. Of course, the display of the specific place displayed on each screen after correction is also changed.

  When maintenance is required according to the analysis result, the maintenance button 56d is clicked continuously. Thereby, the maintenance screen G3e is displayed in the note window G3. The maintenance content, maintenance specifications, cost, and scheduled maintenance date are input to the maintenance screen G3e by the operation unit 15. The input information is sent to the maintenance database 16 by the accompanying maintenance information recording unit 18 and recorded as maintenance instruction information of the displayed maintenance note W.

  Maintenance personnel perform maintenance based on the maintenance instruction information, and in this case, the second pass roll 48b is replaced. After the maintenance is completed, the note window G3 is displayed in the same procedure as described above, and then the maintenance screen G3e is displayed by clicking the maintenance button 56d. Then enter the maintenance date and maintenance status. The input maintenance execution date and maintenance status are sent to the maintenance database 16 by the accompanying maintenance information recording unit 18 and recorded as maintenance result information of the displayed maintenance note W.

  In the case of a failure, a management unit in which a failure can be identified is selected on the hierarchical structure diagram D of the first hierarchy screen G1a or the second hierarchy screen G2a, and a new failure generation button is clicked. As a result of this operation, the maintenance note registration unit 17 generates a new maintenance note W with the basic maintenance information type of “failure” and the selected management unit as the specific location. Thereafter, the main screen G3b based on the generated new maintenance note W is generated by the screen generation unit 23, and the note window G3 is displayed on the display unit 4.

  In the same manner as when an abnormality has occurred, information is input by sequentially displaying each screen. In the case of a failure, after the maintenance result is input, the failure button 56e is clicked to display a failure report screen on the display unit 14, and the report content regarding the failure is input. The input information is recorded in the maintenance note W, and a series of maintenance information recording is completed.

  In order to instruct maintenance separately from the inspection result and failure, a management unit to be maintained is selected on the hierarchical structure diagram D, and a new maintenance button is clicked. The maintenance note registration unit 17 generates a new maintenance note W having the basic maintenance information type “maintenance” and the selected management unit as a specific location, and a note window G3 is displayed on the display unit 14. After this, it is the same as the input of maintenance instruction information and maintenance result when an abnormality occurs.

  By the way, when making a maintenance plan, for example, when judging the maintenance timing, the second history window G2 is displayed or its display is updated. Next, in the hierarchical structure diagram D on the second hierarchy screen G2b, a management unit whose maintenance timing is to be determined or a management unit higher than the management unit is selected.

  When the management unit is selected as described above, as shown in FIG. 14, the information acquisition unit 24 accesses the hierarchy information on the maintenance database 16 and specifies a management unit subordinate to the selected management unit. Then, the maintenance information recorded in the maintenance note W linked to the selected management unit and the maintenance note W linked to the specified management unit is acquired, and the screen is displayed for each maintenance note W. The data is sequentially sent to the generation unit 23.

  When the maintenance information of the first maintenance note W is input from the information acquisition unit 24, the screen generation unit 23 sets the title recorded in the basic maintenance information as the note information R2. Further, the date and type of the basic maintenance information are acquired in association with the note information R2.

  Next, it is checked whether or not the accompanying maintenance instruction information is included in the maintenance information from the information acquisition unit 24. If there is no additional maintenance instruction information, the process for the maintenance information of the first maintenance note W is terminated. On the other hand, when there is accompanying maintenance instruction information, it is checked whether there is further maintenance result information. For example, if there is incidental maintenance instruction information, but there is no maintenance result information, the maintenance content in the incidental maintenance instruction information with “(planned)” added is taken as notebook information R2, and additional maintenance instructions are added to this notebook information R2. The planned maintenance date of information is acquired as a date, and the maintenance instruction is acquired as a type. In addition, when there is incidental maintenance instruction information and maintenance result information, the maintenance status in the maintenance result information is taken as note information R2, and the maintenance execution date of this note information R2 is acquired as a date and the maintenance result is acquired as a type. Is done.

  As described above, after the processing for the maintenance information of the first maintenance note W is performed, the processing for the maintenance information of the second maintenance note W that is input next is the same as the maintenance information of the first maintenance note W. To process. Thereafter, the processing up to the maintenance information of the final maintenance note W is similarly performed. As a result, the total of the maintenance notes W linked to the selected management unit and the maintenance notes W linked to the lower management units is M, of which maintenance instruction information is recorded. If there are N, (M + N) pieces of note information R2 are generated.

  After generating the note information R2 as described above, each note information R2 is classified as maintenance, inspection, or failure based on the type of maintenance information on which the note information R2 is based, and based on the date acquired. The second history screen G2b is generated in the series. At this time, the note information R2 based on the failure information is the date of failure occurrence, the note information R2 based on the inspection information is the abnormality occurrence date, and the note information based on the maintenance instruction information regardless of whether it is basic maintenance information or incidental maintenance information. R2 is a scheduled maintenance date, and note information R2 based on the maintenance order result information is arranged in time series using the maintenance execution date. Note information R2 based on failure information is classified as a failure, and note information R2 based on inspection information is classified as inspection. The notebook information R2 based on the maintenance instruction information and the maintenance instruction result information is classified as maintenance because the corresponding types are the maintenance instruction and the maintenance result. Then, the generated second history screen is displayed in the second history window G2.

  When the management unit “drying area” is specified in the hierarchical structure shown in FIG. 4, the management unit “drying area” and its lower management units “transport device”, “pass roll group”, “drive system” ”,“ First pass roll ”,“ Second pass roll ”,“ Third pass roll ”...“ Drying device ”,“ Air supply unit ”,“ Chamber ”,“ Blower fan ”,“ Blower drive circuit ”, Note information R2 is generated from each maintenance note W that is associated with “blade” and “blower motor”. Then, the second history screen G2b is displayed in a state where the note information R2 is classified into maintenance, inspection, and failure and arranged in time series.

  In the example of the second history screen G2b shown in FIG. 8, there is a maintenance note W linked to the management units “fan fan”, “first pass roll”, “second pass roll”, “third pass roll”, Eight note information R2 generated from the maintenance note W is displayed. Of the eight pieces of note information R2, for example, “third path roll failure” is note information R2 based on failure information (basic maintenance information) of the maintenance note W registered in accordance with the failure of the third path roll. The “third pass roll exchange” is note information R2 based on the maintenance result information of the maintenance note W. Further, “first pass roll replacement (planned)” is the notebook information R2 based on the maintenance instruction information, and it is understood that the maintenance has not been performed.

  If the designated management unit is changed, the maintenance information recorded in the maintenance note W associated with the changed management unit and each lower management unit is acquired, and the second history screen G2b is updated. The Therefore, if the management unit to be selected is changed to a higher one, note information R2 generated from maintenance notes W associated with a larger number of management units in a wider range is displayed on the second history screen G2b. . Conversely, if the management unit is changed to a lower one, the management unit of the displayed note information R2 is narrowed down.

  For example, when the management unit to be selected is changed from “drying area” to “transport device” or “pass group” in the display state shown in FIG. 8, the note information of the management unit “chamber” is displayed on the second history screen G2b. R2 disappears, and only the note information R2 of “first pass roll”, “second pass roll”, and “third pass roll” is displayed.

  In this way, it is possible to grasp the overall maintenance status including various devices, parts, etc. by simply changing the management unit to be selected to the upper or lower level, as well as the maintenance of components such as individual devices and pass rolls. It is also easy to grasp the situation. In addition, it can grasp | ascertain similarly in the 1st log | history screen G1a.

  In addition, since the overall maintenance status can be ascertained, it is easy to compare the occurrence status of abnormalities and failures between two or more devices and parts under the same management unit hierarchy. The right maintenance timing. For example, in the example of FIG. 8, it can be seen that the third pass roll 48c has failed about two months after the occurrence of abnormal noise. From this result, it is predicted that each pass roll will fail without two months from the occurrence of abnormal noise, and the second pass roll 48b is instructed to perform maintenance within a period shorter than two months after the occurrence of abnormal noise. It is carried out. Then, based on the knowledge that the result of examining the second pass roll 48b used so far is just before the limit is reached and that it is appropriate as the replacement time, the first pass roll 48a is not affected by the generation of abnormal noise. It can be judged that maintenance should be carried out in the same period as the time. In FIG. 8, “first pass roll replacement (planned)” is displayed because a maintenance instruction for replacing the first pass roll 48 a is given based on the determination.

  In addition, it is possible to easily grasp the correlation between abnormality or failure between two or more devices and parts, and maintenance implementation. For example, there is a phenomenon that other parts break down after a certain period of time after replacement of a specific part by maintenance, but such a history is displayed for each device or part as in the past, such as It is difficult to discover whether or not a phenomenon has occurred. However, in the second history screen G2b, the abnormality, failure timing, and maintenance timing of each management unit under the same management unit hierarchy can be grasped at the same time, so it is easy to find the above phenomenon. In addition, such a phenomenon makes it possible to determine an appropriate timing for carrying out maintenance. In the example of FIG. 8, the maintenance status of the transport device 45 and the drying device 46 is displayed by selecting the management unit “drying area”.

  In the above, management of the maintenance information of the film forming equipment is exemplified, but the present invention can be used for management of maintenance information of various equipment.
