In the present embodiment, data is transmitted and received to and from the mobile terminal 400. Further, sensor information is received from each hydraulic excavator 200 and is held in the data holding unit 370 as operation information 371 described later. The transmission / reception unit 320 is realized by the communication I / F 315.

The data collection unit 330 collects inspection data transmitted from the mobile terminal 400.

The inspection report creation unit 340 creates an inspection report based on the inspection data collected by the data collection unit 330. At this time, various data held in the data holding unit 370 are used. Details of the data held in the data holding unit 370 will be described later. Further, the created inspection report is stored in the past report DB described later and transmitted to the customer PC 500.

The operation information management unit 350 monitors the operation information described later, and sets an alarm flag when data outside the predetermined range occurs.

On the other hand, the mobile terminal 400 includes a transmission / reception unit 420, an inspection application execution unit 430, an operation unit 440, a photographing unit 450, a position information acquisition unit 460, and a data holding unit 470.

The transmission / reception unit 420 transmits / receives data to / from an external device via the network 101. The transmission / reception unit 420 is realized by the communication I / F 415. In the present embodiment, for example, an inspection application, guidance data, or the like is downloaded from an external server, and the inspection data collected according to the inspection application is uploaded to the management server 300. The downloaded inspection application, guidance data, etc. are saved in the storage device 413 or the like.

The operation unit 440 accepts the operation of the user (here, the serviceman 401) on the mobile terminal 400. In this embodiment, instructions are received via the display 414. The operation unit 440 receives, for example, an instruction for shooting by the camera 416. It also accepts inputs such as various instructions and comments required when the inspection application is executed.

The photographing unit 450 photographs a subject image (here, a subject to be photographed) by the camera 416 and obtains image data. The subject image captured by the camera 416 is displayed in the area (finder area) of the display 414 as an electronic viewfinder. In the present embodiment, when a shooting instruction is received from the serviceman 401, the subject image displayed in the finder area of the display 414 at that time is acquired as image data.

The position information acquisition unit 460 calculates the position information of the mobile terminal 400 from the range-finding satellite data collected by the GPS antenna 417.

The inspection application execution unit 430 executes the inspection application. Here, the installed inspection application is realized by the CPU 411 expanding the memory 412. In the present embodiment, the inspection application execution unit 430 realizes the functions of the aircraft ID reception unit 431, the guidance display unit 432, the data acquisition unit 433, and the guidance data extraction unit 434.

The machine ID reception unit 431 receives input of information (model and machine ID) for identifying the machine of the hydraulic excavator 200 to be inspected.

The guidance data extraction unit 434 extracts guidance data from the data holding unit 470 according to the received model and the received inspection type. The guidance data includes a guidance image, a comment type, and the like, as will be described later. At this time, the guidance data is extracted for all the image data necessary for creating the inspection report for the inspection of the inspection type.

The guidance display unit 432 activates the camera 416 and displays the guidance screen described later on the display 414. Further, the guidance images extracted by the guidance data extraction unit 434 are sequentially displayed one by one in the guidance image display area provided on the guidance screen. At this time, the guidance image and the subject image taken by the camera 416 are combined and displayed in the guidance image display area. The details of the guidance screen will be described later.

When the data acquisition unit 433 receives a shooting instruction from the serviceman 401, the data acquisition unit 433 temporarily saves the subject image displayed on the display 414 as image data at that time. For example, an instruction is given to the photographing unit 450 to acquire the image data, and the image data is temporarily saved. Further, when the input of the comment is received from the serviceman 401, it is temporarily saved in association with the image data displayed in the guidance image display area at that time. These storage destinations are, for example, a storage device 413 or the like.

Further, the data acquisition unit 433 determines the suitability of the image data before transmitting it to the management server 300. The determination here may be only the presence or absence of image data, or may be a simple quality check. For a simple quality check, for example, when an image matching process is executed between the acquired image data and the guidance image using image analysis software and a degree of matching equal to or higher than a predetermined value is shown, it is determined to be appropriate. The degree of matching is determined by the image matching process, for example, in the shooting direction, shooting size, contrast, and the like.

[Data retention unit]
Here, the data held in the data holding unit 370 of the management server 300 and the data holding unit 470 of the mobile terminal 400 will be described. The data holding unit 370 of the management server 300 holds the operation information 371, the vehicle body management information 372, the report data 381, and the past report database (past report DB) 382. Further, the data holding unit 470 of the mobile terminal 400 holds a guidance database (guidance DB) 473 and an inspection database (inspection DB) 474.

The operation information 371 is state data transmitted from the hydraulic excavator 200. A record of the operation information 371 is created and held for each machine and each transmission timing. In each record, for example, as shown in FIG. 5A, the state data 371c is registered for each of the machine ID 371a that identifies the hydraulic excavator 200 and the transmission time 371b of the state data. The registered state data 371c is, for example, a pilot pressure, a pump pressure, a hydraulic oil temperature, an engine speed, an hour meter, and the like.

The vehicle body management information 372 includes vehicle body information 375, customer data 376, and maintenance information 377.

The vehicle body information 375 is information regarding the vehicle body of each hydraulic excavator 200 managed by the management system 100.

As described above, the machine ID 375d is an identification number of each hydraulic excavator 200, and is uniquely set for each vehicle body. A record of vehicle body information 375 is created for each aircraft ID 375d, for example.

The customer data 376 is customer-specific information. In each record of the customer data 376, for example, as shown in FIG. 5C, a customer ID 376a for identifying a customer, a customer name 376b, an aircraft ID 376c used, an industry 376d, and the like are registered. The aircraft ID 376c used is information for identifying the aircraft used by the customer, and the aircraft ID 375d of the vehicle body information 375 is registered.

The maintenance information 377 is the repair history of each vehicle body. In each record of the maintenance information 377, for example, as shown in FIG. 5D, the repair date and time 377b, the repair location 377c, and the repair content 377d are registered for each machine ID 377a.

The inspection DB 474 includes a shooting target database (DB) 478 for registering information (shooting target name) for identifying the shooting target to be posted in the inspection report, and an inspection type DB 479 for registering the inspection type for each part and operation information. Be prepared.

As shown in FIG. 6A, the shooting target DB 478 is a database in which the shooting target name 478c for each inspection type 478b is registered for each model 478a of the hydraulic excavator. The shooting target name 478c may be registered in the order in which the images to be shot are acquired.

The inspection type 478b includes, for example, periodic inspection, inspection for each failure site, inspection for each abnormality occurrence location, inspection for a model having special specifications, inspection according to the type of industry in which the hydraulic excavator 200 is used, and the like.

For example, when the inspection type 478b is "regular inspection", the image of the name plate and the hydraulic excavator 200 viewed diagonally from the front (diagonally front), the image viewed diagonally from the rear (diagonally rear), the monitor, the engine, and the upper swing body 202. , Lower traveling zone, undercarriage, work front 207, for example, attachments such as bucket 212, etc. are registered in this order.

Further, when the inspection type 478b is the "breaker specification machine inspection" specified by the specifications, the breaker piping, the breaker main body (attachment), the breaker specification dedicated parts, and the like are registered in the photographing target name 478c. Further, when the inspection type 478b is "industrial waste inspection" specified by the type of industry used, the radiator core portion, the radiator core portion, etc. are registered in the photographing target name 478c. When the inspection type 478b is "pump abnormality", the sensor unit enlargement for detecting the pump discharge pressure, the harness to the sensor, and the like are registered in the imaging target name 478c. When the inspection type 478b is "hydraulic oil and / or water temperature abnormality", the area around the radiator, the enlargement of the radiator core portion, and the like are registered in the photographing target name 478c.

As shown in FIG. 6B, the inspection type DB 479 registers the inspection type 479b corresponding to the part and the state data (part / state data) 479a. The part / state data 479a corresponds to the state data 371c set in the alarm flag of the operation information 371 and the repair point 377c of the maintenance information 377. In the present embodiment, the guidance data extraction unit 434 is used when selecting the guidance data to be extracted.

As shown in FIG. 7, the guidance DB 473 is a database in which a guidance image 473c and a comment type 473d of each shooting target (shooting target name 473b) are registered for each model 473a of the hydraulic excavator 200. The guidance image 473c is an image that specifies the shooting composition including the orientation of the shooting target, the size in the image, and the like. The comment type 473d is a type of input comment predetermined for each shooting target. The serviceman 401 can input a comment by selecting the state of the shooting target from the comment type 473d. A guidance image or the like may be held for each model of the hydraulic excavator 200.

Note that the comment type 473d may differ depending on the inspection type even if it is the same shooting target. Therefore, it may be registered in association with each shooting target name 478c of the shooting target DB 478.

The report data 381 stores an inspection report form. The inspection report form may be stored for each inspection type, for example. The inspection report creation unit 340 creates an inspection report using the inspection data collected by the data collection unit 330, the inspection report form, the operation information 371, and the vehicle body management information 372. An example of the inspection report will be described later.

The created inspection report is accumulated in the past report DB382. The inspection report itself and the image data, comments, etc. used to create the inspection report are accumulated.

[Guidance screen]
Next, the guidance screen displayed on the display 414 of the mobile terminal 400 by executing the inspection application will be described.

FIG. 8A shows an initial guidance screen 620 displayed on the display 414 when the inspection application execution unit 430 first starts the inspection application. As shown in this figure, the initial guidance screen 620 includes an aircraft ID reception area 621 that accepts input of an inspection type, a model to be inspected, and an aircraft ID. The inspection type does not have to be accepted.

The aircraft ID reception unit 431 receives the inspection type, model, and aircraft ID input from the serviceman 401 via the aircraft ID reception area 621.

The aircraft ID reception area 621 may directly accept input of information for specifying the inspection type, model, and aircraft ID, or holds a list of selectable models and aircraft IDs in advance. It may be configured to be selected from the list.

The list of selectable models and machine IDs may be configured to be transmitted from the management server 300. In this case, the management server 300 side may, for example, receive the transmission of the position information from the mobile terminal 400 and narrow down the list of the model and the machine ID to be transmitted. The management system 100 manages the position information of each customer for each construction machine. For example, centering on the position information of the mobile terminal 400, only the model and the machine ID of the construction machine within a predetermined range may be extracted and transmitted to the mobile terminal 400 as a list.

Next, the guidance screen 610 displayed on the display 414 by the guidance display unit 432 will be described. As shown in FIG. 8B, the guidance screen 610 includes a guidance image display area 611, a shooting instruction reception area 612, a guidance image information display area 613, a comment reception area 614, and a confirmation instruction reception area 615. To be equipped.

The guidance image display area 611 is an area for displaying the guidance image. As described above, the guidance display unit 432 also displays the subject image taken by the camera 416 in the guidance image display area 611. That is, in the present embodiment, the finder area, which is the electronic viewfinder of the camera 416, is set to the guidance image display area 611. When the serviceman 401 acquires the image data, the serviceman 401 can easily obtain the image data having the required composition by matching the subject image displayed in the guidance image display area 611 with the guidance image and taking a picture. The finder area may be set on the entire surface of the display 414, and only the subject image in the guidance image display area may be cut out and acquired as image data.

The shooting instruction receiving area 612 is an area for receiving a shooting instruction. Upon receiving a shooting instruction via this area, the shooting unit 450 acquires the subject image displayed in the guidance image display area 611 at that time as image data.

The guidance image information display area 613 is an area for displaying information on the guidance image displayed in the guidance image display area 611. In the present embodiment, for example, the shooting target name 473b is displayed.

The comment receiving area 614 receives input of a comment by the serviceman 401. The comment may be configured to be selected from, for example, the comment type 473d prepared in advance, or may be configured so that the serviceman 401 can freely input the comment. Input is performed using the text input function of the mobile terminal 400. The comment type 473d is provided in advance as guidance data in association with the guidance image 473c displayed in the guidance image display area 611. It should be noted that the selection from the comment type 473d and the direct input may be combined. For example, only when "with abnormality" is selected, the content of the abnormality is input.

The confirmation instruction receiving area 615 is an area for receiving an intention (confirmation instruction) that has finished acquiring image data and inputting a comment. In the present embodiment, when the confirmation instruction is received via the confirmation instruction reception area 615, the guidance display unit 432 first determines whether or not there is an undisplayed guidance image among the guidance images extracted by the guidance data extraction unit 434. .. Then, when there is an undisplayed guidance image, the next guidance image and the shooting target name are displayed in the guidance image display area 611 and the guidance image information display area 613, respectively. On the other hand, when the display of all the guidance images extracted by the guidance data extraction unit 434 is finished, after temporarily storing in the data acquisition unit 433, all the acquired image data and the like are used as inspection data via the transmission / reception unit 420. Send to the management server 300.

[Flow of inspection support processing]
Next, the flow of the inspection support process by the mobile terminal 400 of the present embodiment will be described. FIG. 9 is a flowchart of the inspection support process of the present embodiment. In the inspection support process of the present embodiment, the serviceman 401 carries the mobile terminal 400, arrives near the hydraulic excavator 200 to be inspected, and inputs the inspection type, the aircraft ID, and the like on the initial guidance screen 620 of the mobile terminal 400. It will be started with that as an opportunity.

When the input of the inspection type, the aircraft ID, and the like is received via the aircraft ID reception unit 431, the guidance data extraction unit 434 extracts the guidance data (step S1101). The details of the guidance data extraction process will be described later.

The guidance display unit 432 displays one guidance image in the guidance image display area 611 of the guidance screen 610 (step S1102). At this time, the guidance display unit 432 activates the camera 416 to display the subject image in the guidance image display area 611.

When the data acquisition unit 433 receives a shooting instruction from the serviceman 401, the data acquisition unit 433 causes the shooting unit 450 to shoot and acquires image data (step S1103). The image data acquired here is a subject image displayed in the guidance image display area 611.

Then, when the data acquisition unit 433 receives the confirmation instruction, the acquired image data is temporarily stored in the storage device 413 or the like. At this time, the image data is saved in association with the name of the imaged portion of the guidance image displayed in the guidance image display area 611. In addition, when a comment is input, the data acquisition unit 433 also saves the comment in association with the name of the imaging site.

The data acquisition unit 433 determines the presence / absence of the next guidance image (step S1104), and if there is the next guidance image, returns to step S1102 and repeats the process.

On the other hand, when there is no next guidance image, that is, when all the images have been taken (step S1104), the data acquisition unit 433 determines the suitability of each acquired image data by the above method (step). S1105).

When it is determined that all are suitable (step S1106), the data acquisition unit 433 transmits all the stored image data and comments to the management server 300 as inspection data (step S1107). When the management server 300 receives the image data and the comment, the inspection report creation unit 340 creates an inspection report using the transmitted inspection data.

On the other hand, if there is image data determined to be inappropriate in step S1106, the data acquisition unit 433 notifies the guidance data extraction unit 434. Then, the guidance data extraction unit 434 re-extracts the guidance data corresponding to the image data (step S1108), returns to step S1102, and repeats the process.

Next, the flow of the guidance data extraction process by the guidance data extraction unit 434 in step S1101 will be described. FIG. 10 is a processing flow of the guidance data extraction process of the present embodiment.

The guidance data extraction unit 434 first determines whether or not the inspection type is specified (step S1201).

When the inspection type is specified, the imaging target DB 478 is referred to, and one or more imaging target names 478c registered in association with the specified model 478a and the specified inspection type 478b are extracted (step S1203).

Then, with reference to the guidance DB 473, the guidance image 473c and the comment type 473d registered in association with each extracted shooting target name 473b are extracted (step S1204), and the process is terminated.

On the other hand, when the inspection type is not specified in step S1201, it is first determined whether or not there is a priority inspection point (step S1211). Here, the guidance data extraction unit 434 accesses the operation information 371 of the management server 300 and determines whether or not there is state data in which abnormal data is generated. For example, if there is state data 371c in which the operation information management unit 350 has set an alarm flag, the state data 371c is extracted as a priority inspection point. In addition, the maintenance information 377 is accessed to determine whether or not there is a repair location 377c registered as a repair history. If the maintenance information 377 has a repair history, the repair location 377c is extracted as a priority inspection location. Here, the priority inspection points to be extracted are not limited to one.

Then, in step S1211, when it is determined that there is a priority inspection point and the priority inspection point is extracted, the inspection is registered in association with the corresponding part / state data 479a (priority inspection point) by referring to the inspection type DB 479. The type 479b is specified (step S1212). The inspection type specified here is not limited to one. Then, after specifying the inspection type 479b, the process proceeds to step S1203. The processing of S1203 and S1204 is repeated for the specified inspection type.

On the other hand, if it is determined in step S1211 that there is no priority inspection point, the inspection type is set to periodic inspection (step S1213), and the process proceeds to step S1203.

Next, FIG. 11 shows a state of change (transition) of the guidance screen 610 displayed on the display 414 in step S1103 of the inspection support process for each processing loop.

Here, the inspection type is a regular inspection, and the name plate 631, diagonally forward 632 of the vehicle body, diagonally rearward 633 of the vehicle body, monitor (hour meter) 634, engine 635, upper swivel body 636, lower traveling zone 637, suspension 638, work front. An example will be illustrated in the case of acquiring image data in the order of 639 and attachment 640.

In this case, each of the above guidance images is set in the above order and transmitted to the mobile terminal 400 as guidance data. Then, as shown in FIG. 11, they are sequentially displayed in the guidance image display area 611.

Each time a new guidance image is displayed, the serviceman 401 matches the guidance image displayed in the guidance image display area 611 with the subject image and takes a picture. Also, enter a comment. After that, an instruction to end shooting is input via the confirmation instruction receiving area 615.

FIG. 12 shows an example of the inspection report 700 created by the inspection report creating unit 340 using the inspection data (image data and comments) acquired as described above.

As shown in this figure, the inspection report 700 includes a vehicle body information area 710 and a main body area 720. In the main body area 720, an image data area 721 and a comment area 722 are provided for each image data.

The inspection report creation unit 340 acquires necessary information from the vehicle body management information 372 and creates the vehicle body information area 710.

Further, the inspection report creating unit 340 attaches the image data of the inspection data collected and saved by the data collecting unit 330 to the image data area 721. At this time, the image size, resolution, and the like may be appropriately processed and displayed. In the comment area 722, the comment and the name of the imaging site transmitted together with the image data are inserted.

As described above, according to the present embodiment, the guidance image showing the shooting composition of the shooting target is displayed on the display 414 of the mobile terminal 400 carried by the serviceman 401, which also serves as the finder of the camera 416. Therefore, the serviceman 401 can obtain image data having a desired composition simply by matching the subject image with the displayed guidance image and taking a picture.

In addition, the guidance images are extracted and displayed for all the images necessary for creating the inspection report. The next guidance image is displayed on the display 414 each time one image data is acquired. Therefore, the serviceman 401 can obtain all the image data necessary for creating the inspection report only by acquiring the image data matching each guidance image according to the guidance.

As described above, according to the present embodiment, it is possible to acquire all the images necessary for creating the inspection report with the intended composition just by taking a picture according to the guidance. That is, according to this embodiment, it is possible to appropriately support the collection of image data necessary for creating an inspection report, and the management system 100 of this embodiment is an image of stable quality regardless of the ability and experience of the serviceman 401. Data can be collected.

Further, according to the present embodiment, an inspection report is created using the image data collected by the above method. Therefore, it is possible to easily create a stable quality inspection report regardless of the ability and experience of the service person.

<Modification example>
In the above embodiment, the mobile terminal 400 collectively transmits the image data to be photographed from the mobile terminal 400. However, it is not limited to this method.

For example, the acquired image data may be transmitted to the management server 300 one by one. In this case, the mobile terminal 400 confirms the suitability each time the image data is acquired.

<Modification 2>
Further, in the above embodiment, the inspection report 700 is created by using only the transmitted inspection data (image data and comments). However, it is not limited to this. For example, the contents of past inspection reports of the Aircraft may be further used.

In this case, the inspection report creation unit 340 creates an inspection report using the latest inspection data and the inspection data (image data and comments) of the same shooting target held in the past report DB382.

For example, as in the inspection report 700a shown in FIG. 13, the inspection data at the time of creating the previous inspection report and the inspection data transmitted this time are described in parallel for the same imaging target.

As a result, it is possible to create an inspection report that can grasp the temporal change of each imaging target, which is an inspection site.

<< Second Embodiment >>
Next, a second embodiment of the present invention will be described. In the first embodiment, in the mobile terminal 400, it is determined only whether or not the acquired image data has a desired quality. However, in the present embodiment, the management server 300 analyzes the transmitted image data and determines the necessity of a new inspection. Then, when it is determined that a new inspection is required, the mobile terminal 400 is notified to that effect. Hereinafter, the present embodiment will be described with a focus on a configuration different from that of the first embodiment.

In the management server 300 of the present embodiment, in addition to the configuration of the first embodiment, as shown in FIG. 14, the data collection unit 330 further includes an inspection result analysis unit 335. Further, as shown in FIG. 6C, the data holding unit 370 further includes a second inspection type DB 380 for storing the inspection type 380b when inspection is required for each analysis result 380a.

The inspection result analysis unit 335 analyzes the inspection data acquired and transmitted by the mobile terminal 400. For example, using existing image analysis software or the like, the image data is analyzed to determine whether or not there are scratches, deformations, etc., and damages of the imaged object.

The inspection result analysis unit 335 also determines the necessity of a new inspection according to the analysis result. The determination is performed based on whether or not the analysis result is registered in the analysis result 380a of the second inspection type DB380. That is, when the analysis result is registered, the inspection result analysis unit 335 determines that a new inspection is required. Then, when it is determined that a new type of inspection is necessary, the required inspection type 380b is specified with reference to the second inspection type DB 380, and the mobile terminal 400 is notified.

When the mobile terminal 400 receives the inspection type notification from the inspection result analysis unit 335, the guidance data extraction unit 434 refers to the photographing target DB 478 and the guidance DB 473, and is registered in association with the inspection type 478b. Guidance data is extracted.

The flow of the inspection support process in this case will be described with reference to FIG. The inspection support process of this embodiment is the same as that of the first embodiment until the inspection data of step S1107 is transmitted.

If a new inspection type is received from the management server 300 within a predetermined time after transmitting the inspection data in step S1107 (step S2101), the process returns to step S1101 and the guidance data extraction unit 434 sets the inspection type to the inspection type. Extract the corresponding guidance data and repeat the process again. The method for extracting guidance data is the same as that in the first embodiment.

On the other hand, if the new inspection type is not received from the management server 300 within the predetermined time in step S2101, the inspection application execution unit 430 ends the process as it is.

As described above, according to the first embodiment, as in the first embodiment, it is possible to appropriately support the collection of image data necessary for creating an inspection report, and the quality is stable regardless of the ability and experience of the serviceman 401. You can create an inspection report for.

Further, according to the inspection result, it is automatically determined whether or not there is an additional inspection, and if necessary, the mobile terminal 400 is notified to perform the re-inspection. Therefore, if you go to the site once, you can cover all the necessary inspections. That is, the serviceman 401 does not have to visit the site many times. Therefore, according to the present embodiment, it is possible to efficiently create an inspection report of stable quality.

In this embodiment as well, the guidance images may be transmitted one by one. In addition, the inspection report to be created may also include the inspection data of the past inspection report.

<Modification example>
In each of the above embodiments, the serviceman 401 is configured to input the model and the machine ID to be inspected, but the present invention is not limited to this. For example, as described above, an imaged portion such as a name plate whose model and machine ID can be specified may be photographed, and the photographed result may be analyzed and identified.

When each machine is equipped with an IC chip in which a model and a machine ID are registered, for example, the mobile terminal 400 communicates by NFC (Near Field Communication) or the like and reads the model and the machine ID in the IC chip. , Model and aircraft ID may be acquired.

Further, in each of the above embodiments, the serviceman 401 acquires image data only for the composition prepared in advance as the guidance image, but the serviceman 401 is not limited to this. It may be configured so that image data of other shooting targets can also be acquired. Further, the mode in which the guidance image is displayed and the image data is acquired may be configured so that the mode in which the image data is acquired without being displayed can be selected.

When the image data of the composition other than the guidance image is acquired, the serviceman 401 inputs the shooting target name corresponding to the acquired image data. The data acquisition unit 433 transmits the image capture target name input together with the image data to the management server 300 via the transmission / reception unit 420. When the image data of the composition other than the guidance image is acquired, the inspection application execution unit 430 registers the image data and the shooting target name in the guidance DB 473 and the shooting target DB 478 as new guidance images. Note that the registration may be performed only when the serviceman 401 determines that registration is required.

Further, in each of the above embodiments, the case where the data held in the guidance DB 473 and the inspection DB 474 is provided to the mobile terminal 400 in advance together with the inspection application has been described as an example, but the present invention is not limited to this configuration. For example, these data may be held by the management server 300 and provided in response to a request from the mobile terminal 400.
