The present invention will be specifically described with reference to the drawings showing the embodiments thereof.
Note that the following embodiment is an exemplification, and the present invention is of course not limited to the configuration shown in the embodiment.

FIG. 1 is an explanatory diagram showing an overview of the maintenance system 100 of the present disclosure. Reference numerals F1 and F2 in FIG. 1 indicate factories, and reference signs A1, A2, A3, and A4 indicate devices installed in the factories F1 and F2. The apparatus A1 (for example, an endurance test apparatus) includes a part C1 (for example, a conveyor chain) and a part C2 (for example, a linear actuator). The device A2 includes a part C3 (for example, a drive chain). The device A3 (for example, a transport device) includes a component C4 (for example, a timing pulley), and the device A4 includes a component C5 (for example, a cable carrier (registered trademark)).

The device A1 incorporates the parts C1 and C2 supplied from the component manufacturer CM, is manufactured by the device manufacturer (or trading company) MC1, and is delivered to the factory F1 of the manufacturing industry. In the apparatus A4, the part C5 supplied from the parts manufacturer CM is manufactured by the embedded apparatus manufacturer MC2 and delivered to the factory F2 of the logistics industry.

An outline of the maintenance system 100 of the present disclosure is that the person in charge (user) of the factories F1 and F2 does not require the mediation of the device manufacturers (or trading companies) MC1 and MC2 that are the suppliers of the devices A1 to A4. This is a system that enables the user to enjoy the maintenance service of C5. For this purpose, the maintenance system 100 of the present disclosure includes a terminal device 1, a server device 2, a network 3, and an identifier 4.

The terminal device 1 is a portable communication device that a user can carry. The terminal device 1 can be connected to the server device 2 via the network 3. The terminal device 1 is preferably a general-purpose device having a camera function (imaging unit) such as a tablet terminal or a smartphone.

The server device 2 is a server computer managed by a parts manufacturer CM. The server device 2 has a Web server function, is connected to the network 3 for communication, and can provide a Web page to the terminal device 1.

The network 3 includes a public network 31 such as the Internet, and a network 32 and a base station 33 of a communication carrier that realizes wireless communication based on a standard such as a next generation or next generation high-speed mobile communication standard. The terminal device 1 can be connected to the server device 2 connected to the public network 31 via the base station 33 and the network 32 under a predetermined security.

The identification body 4 is a seal sheet on which a two-dimensional barcode is printed.

The maintenance system 100 of the present disclosure performs maintenance of the components C1 to C5 of the devices A1 to A4 to which the identification body 4 is attached by an operation of imaging the two-dimensional barcode of the identification body 4 with the camera function of the terminal device 1. It is possible for the terminal device 1 to obtain the information according to the above directly.

Especially when the apparatus A1 in FIG. 1 is taken as an example, the built-in component C1 is a chain and is consumed, so there is a high possibility that the maintenance cycle is shorter than the maintenance of the entire apparatus A1. Therefore, it is efficient that the component manufacturer CM directly carries out maintenance of only the component C1. When the maintenance is performed only for the part C1, information for identifying the part is necessary. However, since the part C1 is a chain, it is difficult to affix an identification seal or the like to itself. By applying the maintenance system 100 of the present disclosure and attaching the identification body 41 for the component C1 to the outer surface of the casing of the device A1 including the component C1, the information on the component C1 is obtained by the terminal device 1 as described above. Obtainable. The identification body 41 for the parts C1 and C2 is bundled together with a registration form at the time of shipment of the parts C1 and C2 from the parts manufacturer CM to the apparatus manufacturer MC1, and further, the apparatus in which the parts C1 and C2 are incorporated by the apparatus manufacturer MC1. When A1 is installed in the factory F1, both are delivered to the factory F1. Thereby, the person in charge of the factory F1 can use the identification body 41 easily. The device manufacturer MC1 does not need to perform maintenance work on the parts C1 and C2 that are not their own products, and only needs to perform maintenance on the in-house developed part of the device A1.

Similarly, when the apparatus A4 in FIG. 1 is taken as an example, the part C5 is particularly a cable carrier (registered trademark), and it is incorporated in the apparatus A4 and provided in a transport unit that transports objects up and down. To do. In this case, it is difficult not only to attach an identification sticker or the like to the part C5 itself, but even if it can be attached, it is difficult to confirm from the outside. By applying the maintenance system 100 of the present disclosure and attaching the identification body 55 for the component C5 to an easily accessible location such as the outer surface of the column of the device A4 including the component C5, the terminal device 1 is attached as described above. Thus, information on the part C5 can be obtained. The identification body 44 for the part C5 is also bundled together with a registration form when the part C5 is shipped from the part maker CM to the apparatus maker MC2, and when the apparatus A4 including the part C5 is installed in the factory F2 by the apparatus maker MC2. Both are delivered to factory F2. Thereby, the person in charge of the factory F2 can use the identification body 44 easily. The same applies to the parts C3 and C4.

The processing performed by the maintenance system 100 configured as described above will be described in the steps of [1: information registration] and [2: information provision].

[1: Information registration]
The maintenance system 100 first requires sticking of the identification body 4 to the devices A1 to A4 and a procedure for registering information regarding the installation of the components C1 to C5 in the server device 2. The procedure for attaching the identification body 4 and registering information on the parts C1 to C5 is performed by the person in charge at the factories F1 and F2, the person in charge of maintenance at the parts manufacturer CM, or both.

When the person in charge at the factories F1 and F2 performs the procedure of pasting and registering information, the identification body 4 and the registration form to be delivered together when the apparatuses A1 to A4 are installed are used. FIG. 5 is an explanatory diagram showing an example of the contents of a registration form in the first embodiment. The registration form may be a postcard, for example, or may be a URL printed on a mail form page. As shown in FIG. 5, the registration slip includes a pasting portion of a registration identifier 4 (the same one that is pasted on the devices A1 to A4) bundled together. The registration form also includes information for identifying the factory F1 and F2 where the devices A1 to A4 including the parts C1 to C5 are installed (company name, business name, factory name, etc.). (Identifiable) is included. The registration form also includes a column for filling in contact information (name, address, telephone number, e-mail address, etc.) for the persons in charge at the factories F1 and F2, and information for identifying the devices A1 to A4 (device name, device number, A column for the name of the device manufacturer is included. In addition, the registration form has an entry field for information (product (part) name, model number, quantity, figure number, and installation date) of the parts C1 to C5 incorporated in the installed devices A1 to A4. Included depending on the number of types.

When the registration slip as shown in FIG. 5 arrives at the parts maker CM by mail, or when an e-mail arrives at the parts maker CM by mail form, the operator performs input processing for the items corresponding to the entry fields. Done. Even if the registration slip or e-mail has not arrived, the person in charge of maintenance of the parts maker CM can learn from the fact that the devices A1 to A4 are installed in the factories F1 and F2. Registration is carried out by going directly to F2 and having the maintenance person fill out a registration form, fill in a mail form, or perform input processing in the same manner as the operator.

Maintenance information for parts C1 to C5 is constructed by input processing by the operator or maintenance staff. FIG. 6 is a flowchart illustrating an example of a construction processing procedure performed by the server device 2.

The control unit 20 of the server apparatus 2 acquires identification information from the registration identifier 4 (step S101). The identification information is recorded so that there is no duplication when printing (issuing) the two-dimensional barcode, and the control unit 20 collates with the record in the two-dimensional barcode issuance system, and the recorded regular identification information. It is good to confirm whether or not.

The control unit 20 receives information for identifying the factories F1 and F2, that is, the customers, such as the company name, the establishment name, the factory name, and the user code (step S102). The control unit 20 refers to the existing customer information DB (see FIG. 7) based on information identifying these customers, extracts corresponding customer information, and associates the extracted customer information with identification information (step S103). ). When the customer information corresponding to the customer information DB does not exist, the control unit 20 performs the process of registering the customer information in the customer information DB together with the process of step S103, issues the corresponding user account information, and contacts the customer To send to.

The control unit 20 receives input of information such as the device name, device number, or device manufacturer name of the devices A1 to A4 including the parts C1 to C5 (step S104). Based on these pieces of information, the control unit 20 refers to the device information DB (see FIG. 7), extracts corresponding device information of another company, and associates the extracted device information with identification information (step S105).

Further, the control unit 20 receives input of information such as product (part) names or model numbers of the parts C1 to C5 (step S106). The control unit 20 refers to the production management information DB and the product information DB (see FIG. 7) based on these pieces of information, and corresponding product information (product (part) name, model number, drawing, lot information, production date). And the like, and the extracted product information is associated with the identification information (step S107). At this time, the control unit 20 may perform association with each order in the DB of the order management system from the device information and the product (parts) information.

The control unit 20 receives input of individual information (quantity, date of introduction, installation position information, etc.) of the parts C1 to C5 included in the installed devices A1 to A4 (step S108), and associates them with the identification information (step S108). Step S109). The control unit 20 stores the above-described various correspondence relationships using the identification information as a key as maintenance information 220 (step S110), and ends the process.

FIG. 7 is an explanatory diagram showing an overview of the maintenance information 220 constructed in the first embodiment. As shown in FIG. 7, individual information (quantity, date, installation, etc.) of the parts C1 to C5 included in the installed devices A1 to A4 in association with the identification information corresponding to the two-dimensional barcode or the wireless tag. Position etc.) is included in the record. In addition, since the record includes the part name, model number, and shipping date of the parts C1 to C5, the records are linked with the production management information, product information, and order management information of the parts C1 to C5. It is possible to track information on when and where the parts C1 to C5 are manufactured and shipped. Further, the record is associated with information on the installation locations (customer information) of the installed devices A1 to A4, that is, current information at the application destination.

By constructing the maintenance information 220 on the server device 2 side in this way, not only the individual information of the parts C1 to C5 but also the information related to the production management at the time of manufacturing the parts C1 to C5, the drawing, etc. Information becomes possible. Thereby, the traceability of the parts C1 to C5 is improved, and various pieces of information regarding the parts are unified on the part manufacturer CM side. When a maintenance service is provided from a parts maker CM, the process up to the installation of the parts C1 to C5 is clarified, so it can be expected that the contents of the service will be enhanced.

[2: Information provision]
Based on the maintenance information 220 as shown in FIG. 7, the user can provide various maintenance information and enjoy a maintenance service. When the user activates the maintenance application program 1P stored in the terminal device 1, input of user account information (user account and login password) is prompted on the application operation screen displayed on the display unit 13. When the user inputs user account information and the server apparatus 2 succeeds in authentication based on the user account information, various maintenance information regarding the components C1 to C5 can be browsed based on the maintenance application program 1P. At this time, the following processing is executed between the terminal device 1 and the server device 2.

FIG. 8 is a flowchart illustrating an example of a processing procedure related to information provision performed by the maintenance system 100 according to the first embodiment.

First, the control unit 10 of the terminal device 1 displays a message for prompting an operation for imaging the identification body 4 by the imaging unit 15 based on the maintenance application program 1P. At this time, for example, the control unit 10 causes the display unit 13 to display a button for imaging the identification body 4 based on the maintenance application program 1P. When the user taps the displayed button, the operation unit 14 detects this, and the control unit 10 activates the imaging unit 15 (step S201) and causes the display unit 13 to display a monitor image of the imaging unit 15. The user moves the terminal device 1 so that the identification body 4 appears in the monitor image. The control unit 10 searches for a predetermined symbol of the two-dimensional barcode from the monitor image, automatically adjusts the focus so as to match the two-dimensional barcode, and automatically detects the two-dimensional barcode when the predetermined symbol is detected. Identification information is acquired from (step S202). In step S202, the control unit 20 may acquire the position information of the terminal device 1 by the GPS receiving unit 18 of the terminal device 1 at the time of shooting.

The control unit 10 adds the acquired identification information to the URL to the Web page provided from the server device 2, and transmits a Web page transmission request using the URL to which the identification information is added (step S203). The URL to the Web page is stored in advance together with the maintenance application program 1P.

When the server device 2 receives a transmission request for the Web page to which the identification information is added from the terminal device 1 (step S301), the control unit 20 uses the added identification information to maintain the maintenance information 220 in the storage unit 22. The corresponding maintenance information is extracted from (step S302). The control unit 20 transmits a Web page (maintenance page in FIG. 8) including maintenance information corresponding to the added identification information to the terminal device 1 (step S303). When position information is added to the transmission request received in step S301, the control unit 20 stores the added position information in association with the maintenance information extracted in step S302.

The terminal device 1 receives the maintenance information Web page transmitted, and displays the maintenance information on the display unit 13 based on the received Web page (step S204).

FIG. 9 is an explanatory diagram showing an example of the content of maintenance information displayed on the terminal device 1. FIG. 9 shows a layout of a maintenance information display screen 300 displayed on the display unit 13 of the terminal device 1 that is a smartphone.

Further, the “device details” link is included in the information column of the device A1. When the “Device Details” link is selected, a page including device information associated with the device code in the device information DB, such as the name of the person in charge, contact information, etc., is further displayed. .

The maintenance information further includes information on the parts C1 and C2 incorporated in the device A1. Since the information on the part C2 included in the maintenance information displayed in FIG. 9 is the same as the information on the part C1, details of the displayed contents are omitted. “Product name” and “model number” are displayed as information of the part C1. Further, the number of parts C1 incorporated is displayed as “quantity”. The information of the part C1 includes an “image” link, and when the “image” link is selected, a product image of the part C1 (an image provided from the part manufacturer CM or registration of maintenance information) Sometimes images taken) may be displayed.

The information of the part C1 in the displayed maintenance information includes the associated “drawing number”, and the “drawing number” includes a “drawing pdf” link. When the “drawing pdf” link is selected, the pdf viewer is activated based on the maintenance application program 1P, and a drawing image that can be acquired by “drawing number (drawing number)” is displayed.

The information of the part C1 in the displayed maintenance information may include the associated test number. These pieces of information are obtained by extracting information associated with the production management information DB in the server device 2.

The information of the part C1 in the displayed maintenance information includes information individually registered for the part C1 incorporated in the apparatus A1 installed in the factory F1, that is, the shipping date, the installation date, and the use start date. It is included. An order number may be displayed. Also, the previous replacement date (blank in FIG. 9) and the next replacement date are displayed in the same manner. The next replacement date is the date derived from the average operation time of the product (part C1) linked in the product information DB in the server device 2. Since the next replacement date differs depending on the use environment, it may be automatically calculated by another system based on various conditions registered by the maintenance staff. Further, the next replacement date may be calculated as the date of addition of the service life (for example, 5 years) previously determined for each product and stored in the product information DB. .

In this way, the user activates the maintenance application program 1P on the terminal device 1 and takes an image of the identification body 41 attached to the outer surface of the device A1, whereby the component C1 and the component included in the device A1. It becomes possible to know the maintenance information of C2 directly. Further, since the server apparatus 2 transmits information based on the maintenance information 220 constructed at that time, the latest appropriate information can be obtained. Appropriate information derived based on information from the parts manufacturer CM is also provided at the time when replacement is estimated to be necessary.

In the example shown in FIG. 9, a support request button (icon) 301 and an estimate request button (icon) 302 are further displayed for each component C1. The processing when these buttons are selected will be described by returning to the flowchart of FIG.

When the maintenance information is displayed as shown in FIG. 9, the control unit 10 of the terminal device 1 determines whether or not the tap of the support request button 301 is detected by the operation unit 14 (step S205). When it is determined that the tap of the support request button 301 has been detected (S205: YES), the control unit 10 acquires and displays the support screen from the server device 2, and the device A1 in which the component C1 is incorporated on the support screen. Access to the dedicated window is accepted (step S206). The dedicated window may be a telephone reception, a dedicated mail form, or only a request transmission button. The content of support may be selectable on the support screen. As options, there may be, for example, an inspection request, a telephone response request, or a question only. The control unit 10 transmits the content of the support request to the server device 2 based on the access received on the support screen (step S207). The content of the support request may include information for identifying the component C1 and the information of the device A1 in which the component C1 is incorporated.

On the other hand, the server apparatus 2 receives and accepts the support request content through the communication unit 23 (step S304). Specifically, when receiving the content of the support request, the control unit 20 refers to the maintenance information 220 based on the information for identifying the component C1 and the device A1 included in the support request content, and sets the associated customer information. Extract. As a result, the control unit 20 can identify the support request source factory F1, the person in charge, the contact information of the person in charge, the support target apparatus A1 and the part C1 at the dedicated window. Except when the dedicated window is a telephone reception, the control unit 20 of the server apparatus 2 sends an e-mail including the support contents included in the support request contents and corresponding maintenance information such as the parts C1, the apparatus A1 and the like to be supported. It may be automatically transmitted to the maintenance personnel of the parts manufacturer CM. At this time, it is preferable that a map image (showing the installation location of the device A1 in the factory) based on the location information of the device A1 included in the maintenance information and the location where the device A1 is installed is preferably included.

When an inspection at the factory F1 is performed in response to a support request, the maintenance result of the parts manufacturer CM gives an explanation to the person in charge (customer) of the factory F1, and the result of the inspection is displayed. The maintenance information 220 may be stored in association with the identification information. This makes it possible to easily refer to the previous inspection result at the next inspection.

If it is determined in step S205 that a tap on the support request button 301 is not detected (S205: NO), the control unit 10 determines whether a tap on the estimate request button 302 has been detected (step S208). When it is determined that the tap of the estimate request button 302 has been detected (S208: YES), the control unit 10 receives the quantity of the component C1 and the like, and sends an estimate request including information for identifying the component C1 and the device A1 to the server device 2. It transmits to the address (step S209). In step S209, the control unit 10 and the control unit 10 return to the display of maintenance information and continue the display until an instruction to end the operation based on the maintenance application program 1P is given.

On the other hand, in the server device 2, the communication unit 23 receives and accepts an estimate request, and executes an issuance procedure (step S305). In step S305, when the control unit 20 specifically receives an estimate request, the control unit 20 refers to the maintenance information 220 based on information for identifying the component C1 and the device A1 included in the estimate request, and associates customer information. To extract. As a result, the control unit 20 can identify the factory F1, the person in charge, the contact information of the person in charge, the device A1 to be supported, and the component C1 based on the extracted customer information. The control unit 20 transmits the customer information to the order management system together with the information and quantity of the part C1 included in the estimate request, extracts the unit price of the part C1 from the product information DB in the order management system, and estimates based on the customer information. Implement issuing procedures. The contents of the estimate issued at this time may be transmitted from the server device 2 to the terminal device 1 so as to be visible on the display unit 13 of the terminal device 1 and displayed on the terminal device 1.

If it is determined in step S208 that the tap of the estimate request button 302 is not detected (S208: NO), the control unit 10 continues to display the maintenance information and is instructed to end the operation based on the maintenance application program 1P. If so, the process ends.

In this way, the user of the devices A1 to A4 can receive the direct maintenance service by the server device 2 managed by the component manufacturer CM for the information on the components C1 to C5 incorporated in the devices A1 to A4. . In addition to browsing the latest and appropriate maintenance information of the incorporated parts C1 to C5, the user can easily execute a support request, a request for quotation, etc. by tapping a button displayed together with the maintenance information. .

For example, assuming that the maintenance cycle of the entire apparatus A1 is 3 to 5 years, for the parts C1 and C2 incorporated in the same apparatus A1, the former maintenance cycle is 1 year and the latter maintenance cycle is 3 years. It may be. In such a case, it is possible to receive a maintenance service for each of the incorporated parts C1 and C2. By applying the maintenance system 100 of the first embodiment in this way, the traceability of the parts C1 to C5 is improved, and the maintenance service can be enhanced.

Also, as described above, when the position information of the terminal device 1 when the identification body 4 is imaged is transmitted together with the maintenance information transmission request, it is stored as the maintenance information 220. Thus, the maintenance staff of the parts manufacturer CM can know the details of the latest locations of the devices A1 to A4 in which the parts C1 to C5 are incorporated. Even if the locations of the devices A1 to A4 are moved, they are updated at the timing of the maintenance information transmission request. The first storage of the position information may be performed in advance by the maintenance staff when the maintenance staff first visits the site after installing the devices A1 to A4 incorporating the parts C1 to C5.

Note that the support request button 301 and the estimate request button 302 shown in FIG. 9 have been described as being displayed like buttons. However, since the button here is what is displayed on the display part 13 of the terminal device 1 which is what is called a smart phone, of course, these may be displayed in the form of an icon. .

(Modification)
FIG. 10 is a schematic diagram of the identification body 4 in the modification. In the modification, the identification body 4 has a multi-layer structure of a two-dimensional barcode printing layer, an intermediate layer, and an adhesive layer. And as shown in FIG. 10, the tag layer which formed in the resin layer the conductor 49 which comprises the IC chip and antenna of a wireless tag (for example, RFID tag) between the two-dimensional barcode printing layer and the intermediate | middle layer is included. Identification information corresponding to the identification information of the two-dimensional barcode printed on one surface is stored in the IC chip of the tag layer. When the information is stored in the IC chip, the identification information is controlled to be the same identification information in the above issuing system, or the identification information stored in the IC chip and the two-dimensional bar code A correspondence relationship with the identification information is stored in the issuing system. The form of the identification body 4 including the wireless tag is not limited to the seal sheet, and may be a chip shape.

The terminal device 1 in the modification is configured to be connected to or built in a wireless tag reader capable of reading information from the wireless tag included in the identification body 4. The terminal device 1 does not have to include the imaging unit 15. In this case, the control unit 10 of the terminal device 1 activates the wireless tag reader and acquires information from the identification body 4 in step S202 in the processing procedure shown in the flowchart of FIG. Subsequent processing is the same as that of the configuration in which the imaging unit 15 is provided.

Thus, even when the devices A1 to A4 themselves are installed in places where access is difficult due to the configuration in which the identification body 4 incorporates the IC tag and the terminal device 1 has a tag reader function, the devices A1 to A4 It becomes possible to obtain maintenance information of the parts C1 to C5 included in A4. In addition, after the fact, other machines are installed around the devices A1 to A4, and even if it becomes difficult to access the devices A1 to A4 and imaging becomes difficult, the terminal device 1 uses the components C1 to C5. Maintenance information can be acquired.

In addition, if the identification body 4 is the structure which can acquire the information which identifies each from the terminal device 1, the form of the seal sheet in which the two-dimensional barcode is printed, or the form which incorporates the above-mentioned IC tag Either one. Furthermore, only a wireless tag may be used. When only the wireless tag on which the two-dimensional barcode is not printed is used, the terminal device 1 may have a tag reader function but may be a reader terminal that does not have a camera function. The configuration for acquiring the identification information from the identification body 4 by wireless communication not only uses an IC tag such as an RFID for the identification body 4 but also a wireless communication such as Bluetooth (registered trademark) or Wi-Fi from the identification body 4. The information may be acquired by communication. The two-dimensional barcode can be replaced with a one-dimensional barcode, or a color code.

(Embodiment 2)
In the second embodiment, a service for notifying the replacement timing of the parts C1 to C5 from the server device 2 side is realized. In this case, notification is performed based on an analysis process executed in the server device 2.

FIG. 11 is a block diagram illustrating an internal configuration of the server apparatus 2 according to the second embodiment. In the second embodiment, the server device 2 stores an analysis program 3P in the storage unit 22 in advance, and can execute an analysis process described later based on the analysis program 3P. The analysis program 3P may be a program in which the control unit 20 duplicates the analysis program 7P read from the recording medium 7 by the reading unit 24 in the storage unit 22.

FIG. 12 is an explanatory diagram illustrating an example of the content of maintenance information displayed on the terminal device 1 according to the second embodiment. As shown in FIG. 12, in the second embodiment, the display screen 300 displayed based on the maintenance information Web page transmitted from the server device 2 further includes a button called a status acquisition button 303 for the component C1. Since other display contents included in the display screen 300 are the same as those described with reference to FIG. 9 in the first embodiment, detailed description thereof will be omitted.

A processing procedure when the state acquisition button 303 in the second embodiment is selected will be described with reference to a flowchart. FIG. 13 is a flowchart illustrating an example of a processing procedure related to information provision performed in the maintenance system 100 according to the second embodiment. Of the processing procedures shown in the flowchart of FIG. 13, the steps common to the processing procedure shown in the flowchart of FIG. 8 are given the same step numbers, and detailed description thereof is omitted.

In the terminal device 1 according to the second embodiment, when it is determined in step S208 that the tap of the estimate request button 302 is not detected (S208: NO), the control unit 10 taps the status acquisition button 303 in the operation unit 14. It is determined whether or not it has been detected (step S210).

If it is determined in step S210 that a tap on the status acquisition button 303 has been detected (S210: YES), the control unit 10 acquires the status of the component C1, and obtains the status acquisition result as the component C1 and the device including the component C1. It transmits to the server apparatus 2 with the identification information of A1 (step S211). Specifically, the acquisition of the state in step S211 is realized by acquiring a captured image obtained by imaging the component C1 using the imaging unit 15. The acquisition of the state may be a result of collecting the operation sound of the component C1 using the sound collecting device included in the terminal device 1. Further, signal data from an existing sensor provided in the terminal device 1 or a sensor (rotation sensor, shock sensor, etc.) built into the component C2 itself in the case of the component C2, for example, may be acquired.

On the other hand, the server device 2 receives the state acquisition result transmitted from the terminal device 1 (step S306), and the control unit 20 executes processing for analyzing the state of the component C1 from the state acquisition result based on the analysis program 3P. (Step S307). An example of the content of the analysis process will be described later. The control unit 20 stores the result of the analysis process in the maintenance information 220 in association with the identification information and transmits it to the terminal device 1 (step S308).

The terminal device 1 receives the analysis result transmitted from the server device 2, and displays the analysis result (necessity of maintenance) on the display unit 13 (step S212). Then, the control unit 10 continues to display the maintenance information, and ends the process when an instruction to end the operation based on the maintenance application program 1P is given.

If it is determined in step S210 that the tap on the status acquisition button 303 is not detected (S210: NO), the control unit 10 continues to display the maintenance information and is instructed to end the operation based on the maintenance application program 1P. If so, the process ends.

FIG. 14 is a flowchart illustrating an example of an analysis processing procedure performed by the server device 2. In the processing procedure shown in the flowchart of FIG. 13, an example in the case of using an image obtained by imaging the component C1 corresponding to the details of step S307 will be described.

The control unit 20 of the server device 2 acquires the captured image received from the terminal device 1 (step S41), and specifies the dimensions in the captured image (step S42). In step S42, the control unit 20 specifies a dimension from an object whose dimension is known in the captured image. For example, at the time of status acquisition, it may be determined that a predetermined ruler is imaged together. Further, in the case of the captured image of the part C1, it may be specified from the dimension of a part that changes as little as possible, such as a plate that is a part of the chain.

And the control part 20 specifies the chain pitch of the component C1 based on the dimension specified by step S42 (step S43). At this time, the chain pitch may be an average of the chain pitches of a plurality of links.

The control unit 20 acquires the dimension of the part C1 on the drawing, that is, the dimension of the part C1 before use, and the threshold value related to the chain pitch elongation diagnosis from the maintenance information 220 of the storage unit 22 (step S44). Accordingly, since the maintenance information 220 needs a threshold value for chain pitch elongation diagnosis in advance, it is stored in the product (part) information DB in association with the product code.

The control unit 20 determines whether or not there is wear elongation depending on whether or not the chain pitch specified in step S43 is longer than the threshold acquired in step S44 (step S45). If it is determined in step S45 that the wearer is long and wear-extended (S45: YES), the control unit 20 determines that the part C1 should be replaced promptly and executes a replacement order procedure (step S46). Returning to step S308 of the flowchart of FIG. In this case, the terminal device 1 may be notified that “I placed an order because replacement is necessary”. The replacement order procedure in step S46 refers to the maintenance information 220, extracts the associated customer information, and transmits the extracted customer information, the identification information of the part C1, and the quantity to the order management system. Will be implemented.

If it is determined in step S45 that it is equal to or smaller than the threshold value (S45: NO), the control unit 20 needs to be replaced based on the chain pitch specified in step S43 and the dimensions before use acquired in step S44. Is predicted (step S47). Then, the control unit 20 returns the process to step S308 in the flowchart of FIG. In this case, the control unit 20 may update the next replacement date in the maintenance information 220 to that obtained by prediction.

Next, the process of step S43 in the flowchart of FIG. 14 will be described with a specific example. FIG. 15A, FIG. 15B, and FIG. 15C are explanatory diagrams showing an outline of the analysis process. FIG. 15A is a diagram illustrating an example of the captured image acquired in step S41. The picked-up image shows the plate surface of the conveyor chain, which is the component C1, and the end surface of the pin.

In step S43, based on the analysis program 3P, the control unit 20 first extracts the region of the end face of the pin from the captured image. FIG. 15B shows a region of the end face of the extracted pin as a black region. The control unit 20 specifies the center of each end face region, and specifies the average P of the center distance between the end face regions as the chain pitch. In FIG. 15C, the center of each end face region is indicated by a point, and the identified chain pitch is indicated by a symbol P. In FIG. 15C, a dimension D specified from other than the end face of the pin shown in FIG. 15A is shown. This makes it possible to estimate the actual size of the center distance between the end face regions in the image.

Note that the chain pitch is not limited to the distance between the centers of the end face regions of each pin in FIG. 15B. For example, the average of the distance measured between the pins for a plurality of links, for example, relative to the left end in the figure in the end face area of the pin, and the number measured in relation to the right end in the figure in the end face area is the number of pins. Various methods such as using a numerical value divided by a value of −1 may be employed. Needless to say, the presence / absence of wear elongation may be determined not only by the chain pitch but also by other factors.

In this way, the user can determine the deterioration state of the component C1 obtained from the captured image by analysis in the server device 2 by a simple operation of capturing the image of the component C1. When the user selects the support request button 301 after selecting the status acquisition button 303, the server apparatus 2 stores the analysis result in association with the identification information related to the component C1. Therefore, it becomes possible to grasp the deterioration state although it is accurate to some extent before the maintenance staff of the parts manufacturer CM visits the factory F1. The maintenance staff grasps whether or not a replacement order for a new part C1 has been placed, and if the replacement order has been placed, the efficiency is improved, for example, by matching the timing of the visit with the delivery of the part C1. It is also possible to appropriately prepare other necessary maintenance tools.

Thus, the traceability of the parts C1 to C5 is improved, and an appropriate maintenance service can be realized without requiring the mediation of the device manufacturers MC1 and MC2.

14 and FIGS. 15A to 15C are based on images, but as described above, sound data obtained by collecting operation sounds may be used as a result of state acquisition. When using the sound collection data, the control unit 20 determines whether or not the replacement is necessary based on the characteristics of the frequency or the comparison with the sound data at the normal time, and predicts the replacement time when the replacement is unnecessary. It may be. Even when a shock sensor or the like is used, it is preferable to store threshold information to be compared with the maintenance information 220 of the server device 2 in the product information DB and compare it to determine the deterioration state.

In this way, it is possible to prevent the occurrence of problems in the devices A1 to A5 by automatically determining the different deterioration states of the components C1 to C5 by executing the analysis processing on the server device 2 side. Increases nature. By determining the deterioration state on the server device 2 side, the latest information on the components C1 to C5 held on the component manufacturer CM side is reflected, and more appropriate determination is possible.

In the second embodiment, the analysis process based on the analysis program 3P is performed by the process of the control unit 20 of the server device 2. However, the configuration is not limited to this, and the analysis system is included in the maintenance system 100 separately from the server device 2, and the control unit 20 of the server device 2 executes analysis processing in the analysis device and acquires the analysis result from the analysis device. It is good also as a structure.

(Embodiment 3)
In the first embodiment, in [1: Information registration], the operator or maintenance of the component manufacturer CM based on the pasting of the identification body 4 by the person in charge at the factory F1, F2 and the sending of the registration slip corresponding to the identification body 4 Maintenance information 220 is constructed by input processing by the person in charge (see FIG. 6). In the third embodiment, after the identification body 4 is attached to the devices A1 to A4, the maintenance information 220 is updated using the terminal device 1.

As shown in FIG. 1 in the first embodiment, for example, at the initial installation stage of the device A1 in the factory F1, the component C1 supplied from the component manufacturer CM to the device manufacturer MC1 for incorporation into the device A1. , C2 is supplied with the identification body 41 and delivered to the factory F1. After that, the person in charge at the factory F1 can directly receive the maintenance service from the component manufacturer CM without going through the device manufacturer MC1 at the stage [2: Information provision] shown in the first or second embodiment. Therefore, replacement of the parts C1 and C2 included in the apparatus A1, replacement parts, or additional parts are delivered directly from the parts manufacturer CM to the factory F1. In the third embodiment, the parts C1 to C5 are replaced after the initial installation stage, and the traceability of the alternative parts or the additional parts is improved.

FIG. 16 is an explanatory diagram showing a flow of parts delivery in the third embodiment. As shown in FIG. 16, in the third embodiment, the flow of delivery of the part C6 when a part C6 (for example, a sprocket) is newly added (replaced) to the device A1 is shown. An identification body 45 for identifying the component C6 itself is attached to the component C6 and is packaged. At this time, it is not necessary to attach a registration card to the identification body 45 as in the initial installation stage.

The identification body 45 is one of the identification bodies 4 and a seal sheet on which a two-dimensional barcode is printed. It is assumed that the unique identification information included in the two-dimensional barcode of the identification body 45 of the part C6 is recorded in the order management information DB in advance in association with the part name, model number, quantity, shipping date, and the like at the time of shipment. . Therefore, by referring to the record such as the product information DB and the production management information DB based on the identification information included in the two-dimensional barcode of the identification body 45, it is possible to track information on when and where the part C6 is manufactured and shipped. is there.

The configuration of the maintenance system 100 in the third embodiment is the same as that in the first and second embodiments, and the above-described component identification body 45 and the information registration process shown below are added.

FIG. 17 is an explanatory diagram illustrating an example of a screen displayed on the terminal device 1 according to the third embodiment. The screen example of FIG. 17 is a portal screen 310 for each user that is displayed when the user inputs user account information and the server apparatus 2 side succeeds in authentication based on the user account information. As shown in FIG. 17, the portal screen 310 includes a maintenance information acquisition button (icon) 304 for acquiring individual information by imaging the identification body 4. When the maintenance information acquisition button 304 is tapped, a list of maintenance information of the components C1 to C5 for each of the devices A1 to A4 is displayed by the processing procedure shown in the flowchart of FIG. 8 of the first embodiment.

Then, as shown in FIG. 17, the portal screen 310 further includes a parts registration button 305. Processing when the component registration button 305 is selected (tapped) will be described below with reference to a flowchart. In the following description, a case where the person in charge at the factory F1 shown in FIG. 1 selects the component registration button 305 using the terminal device 1 will be described as an example. As shown in FIG. 17, the portal screen 310 may include buttons (icons) that can accept registration information change regarding the factory F, accept setting changes, and the like.

FIG. 18 is a flowchart illustrating an example of a processing procedure related to information registration performed in the third embodiment. When it is determined that the tap of the component registration button 305 is detected by the operation unit 14 of the terminal device 1, the following processing is executed between the terminal device 1 and the server device 2.

When the control unit 10 determines that the tap of the component registration button 305 has been detected, the control unit 10 activates the imaging unit 15 (step S701), and a button for imaging the identification body 4 based on the maintenance application program 1P. The monitor image is displayed on the display unit 13. At this time, the control unit 10 displays a message prompting an operation for imaging the identification bodies 41 to 44 already attached to the devices A1 to A4 to which the components C1 to C6 are to be added (step S702). The user moves the terminal device 1 so that the identification bodies 41 to 44 appear in the monitor image. The control unit 10 searches for a predetermined symbol of the two-dimensional barcode from the monitor image, automatically adjusts the focus so as to match the two-dimensional barcode, and automatically detects the two-dimensional barcode when the predetermined symbol is detected. The identification information (parent) of the identification bodies 41 to 44 already affixed is acquired (step S703).

Next, the control unit 10 activates the imaging unit 15 again (step S704), and causes the display unit 13 to display a button and a monitor image for imaging the identification body 4 based on the maintenance application program 1P. At this time, the control unit 10 displays a message that prompts an operation for imaging the unattached identification body 45 that has been bundled with the part to be added (step S705). The user moves the terminal device 1 so that the identification body 45 appears in the monitor image. When the control unit 10 detects a predetermined symbol of the two-dimensional barcode, it automatically acquires identification information (child) of the identification body 45 from the two-dimensional barcode (step S706).

The control unit 10 transmits the acquired identification information (parent) and identification information (child) as an information registration request to the server device 2 (step S707).

When the server apparatus 2 receives the information registration request from the terminal apparatus 1 (step S801), the control unit 20 determines from the maintenance information 220 based on the identification information (parent) and identification information (child) transmitted together. The maintenance information corresponding to the identification information (parent) is extracted (step S802). The control unit 20 adds individual information (part number, quantity, shipping date) from the record in the order management information DB stored in association with the identification information (child) in the maintenance information corresponding to the identification information (parent). Extract and link (step S803). Further, the control unit 20 may extract information of other individual information (product number, number of lots, production date, etc.) from the product information DB and the production management information DB corresponding to the identification information (child). The control unit 20 updates the maintenance information 220 by associating the extracted information with the identification information (parent) (step S804), and ends the process.

FIG. 19 is an explanatory diagram showing an outline of the maintenance information 220 updated in the third embodiment. The content example of the maintenance information 220 in FIG. 19 shows a change to the initial maintenance information 220 shown in FIG. Specifically, a record for the part C6 is added. In the example of FIG. 19, the identification information (child) of the part C6 is added as an item of the maintenance information 220, but it is not essential. And when the information registration of the component C6 shown in Embodiment 3 is performed, the identification body 45 enclosed with the component C6 does not need to be stuck on apparatus A1. This is because the identification body 45 is mainly used for information registration of the above-described component C6 in the third embodiment. The two-dimensional barcode of the identification body 45 is stored in the factory F1, and the person in charge takes an image with the imaging unit 15 of the terminal device 1, so that the maintenance information of the component C6 alone is displayed on the display unit 13 of the terminal device 1. It may be possible to display with.

As described above, the maintenance information 220 is updated using the identification body 4 included in the component C6 on the terminal device 1 side, so that one identification body 4 is provided for each of the devices A1 to A4 or for one production line. By using it, it becomes possible to provide maintenance information for the parts C1 to C6. Even when the parts C1 to C6 are added or exchanged, it is possible to link the update of new information to the original identification body 4, so that one identification is made for an apparatus or equipment including a large number of parts. With a simple configuration in which only the body 4 is attached, it is possible to provide various information and enhance services.

(Embodiment 4)
