<Display Control Processing Procedure in Control Device 30>
FIG. 6 is a flowchart illustrating an example of a display control processing procedure in the control device. In the example shown in FIG. 6, the following display control processing is performed for the display of machine information. In the following description, it is assumed that machine information about the construction machine 10 is stored in the memory 35 or the like in advance.

  In the control device 30, the controller 36 determines whether or not there is a setting by a user such as a driver or a maintenance worker for the display of the machine information (S01). The user setting includes, for example, at least one of the above-described password input and serial number input, machine information type and period setting, etc., but is not limited to this in the present invention. is not.

  If there is a user setting (YES in S01), the controller 36 generates a two-dimensional barcode for the machine information extracted from the memory 35 or the like based on the set information (S02). If there is no user setting (NO in S01), a two-dimensional barcode is generated for machine information extracted from the memory 35 or the like based on preset information (S03). Note that the preset information includes the type of machine information and the setting of a period, but the present invention is not limited to this.

  Next, in the process of S02 or S03, the extracted two-dimensional barcode is displayed on the display unit 22 (S04). The display in S04 is performed for a predetermined time, for example. In the present invention, the display is not limited to this. For example, the display may be performed until the user presses a screen-off (OFF) switch or performs a power-off (OFF) operation.

  After the display by the process of S04, a deletion confirmation display for instructing the user whether or not to delete the information displayed by the two-dimensional barcode from the memory 35 or the like is performed (S05). Here, it is determined whether there is a deletion instruction (S06). If there is a deletion instruction (YES in S06), the corresponding data corresponding to the two-dimensional barcode is deleted (S07). If there is no deletion instruction in the process of S06 (NO in S06), it is next determined whether or not there is data that has passed a predetermined time for data such as machine information stored in the memory 35. (S08). Here, the predetermined time may be, for example, an accumulated time from the start of accumulation of machine information, or may be a predetermined number of days. Further, in the present embodiment, determination may be made based on whether or not a predetermined number of times is exceeded in comparison based on frequency information such as the number of operations, not on time comparison.

  In the process of S08, if there is data that has passed the predetermined time (YES in S08), the corresponding data that has passed the predetermined time is deleted (S09).

  Next, in the process of S07, the process of S09, or the process of S08, when there is no data for which a predetermined time has elapsed for the machine information data stored in the memory 35 (NO in S08), another machine It is determined whether or not to display information (S10). When other machine information is displayed (YES in S10), the process returns to the process of S01, the user setting for acquiring other machine information is performed, and the subsequent process is performed. If no other machine information is displayed in the process of S10 (NO in S10), the process ends.

  Note that the two-dimensional barcode display shown in S04 described above may automatically display a two-dimensional barcode on the display unit 22 when the construction machine 10 is keyed off, or may display the two-dimensional barcode when the construction machine 10 fails. You may display automatically on the display part 22. FIG.

  Furthermore, in the present embodiment, the above-described processing procedure of only S05 to S09 may be separately provided as a data deletion processing procedure in the control device 30.

<Machine Information Display Control Procedure in Portable Terminal 40>
FIG. 7 is a flowchart illustrating an example of a display control processing procedure in the mobile terminal. In the process shown in FIG. 7, first, the portable terminal 40 reads the two-dimensional barcode displayed on the display unit 22 of the construction machine 10 and acquires the date and time when the two-dimensional barcode is read from the date and time acquisition unit 70 of the portable terminal 40. (S21) Next, the position information of the mobile terminal 40 is acquired and the date and time when the position information is acquired is acquired from the date and time acquisition unit 70 of the mobile terminal 40 (S22).

  In addition, although the GPS etc. which were mentioned above can be used for the positioning for acquiring the positional information in the portable terminal 40, for example, in this invention, it is not limited to this. For example, it is possible to perform positioning based on position information of a base station in a mobile phone network or position information of a base station of a public wireless LAN (Local Area Network) that is fixedly installed. Further, the date and time acquired by the process of S21, the position information measured by the process of S22, and the acquired date and time are added to related machine information and stored in the memory 69 or the like.

  Next, the portable terminal 40 determines whether or not to analyze the two-dimensional barcode (S23). When the portable terminal 40 analyzes the two-dimensional barcode (YES in S23), the two-dimensional barcode is analyzed. Then, the machine information embedded in the two-dimensional barcode is extracted (S24). Thereafter, it is determined whether or not to display the machine information embedded in the analyzed two-dimensional barcode (S25).

  In the process of S25, for example, the user may input the above-described password or the serial number of the construction machine 10, and may determine whether to display the machine information based on the input information. However, the present invention is not limited to this.

  In the process of S25, when machine information is displayed (YES in S25), the machine information is displayed on the display unit 64 of the portable terminal 40 (S26). Here, after the process of S26 is completed, when the machine information is not displayed in the process of S25 (NO in S25), or when the two-dimensional barcode is not analyzed in the process of S23 (NO in S23), the construction machine 10 Delete confirmation display for instructing the user whether or not to delete the information acquired from (S27).

  Note that the deletion confirmation display in S27 can display, for example, the above-described screen shown in FIG. 3D on the display unit 64, but the present invention is not limited to this.

Here, it is determined whether there is a deletion instruction (S28). If there is a deletion instruction (YES in S28), the corresponding data corresponding to the two-dimensional barcode, the two-dimensional barcode, etc. is deleted (S29). . In the process of S28, if there is no deletion instruction (NO in S28), the corresponding data corresponding to the two-dimensional barcode, the two-dimensional barcode, etc. is stored in the memory 69 (S30).
Next, it is determined whether data such as machine information stored in the memory 69 has passed a predetermined time (S31). Here, the predetermined time may be, for example, an accumulated time from the start of accumulation of machine information, or may be a predetermined number of days. The predetermined time includes, for example, information such as the accumulated time and the number of operations previously included in the machine information embedded in the two-dimensional barcode, the date and time acquired when the two-dimensional barcode is read, and the determination in S31 It can also be determined based on the elapsed time determined from the date and time of the time.

  In the process of S31, if there is data that has passed the predetermined time (YES in S31), the corresponding data that has passed the predetermined time is deleted (S32), and the process proceeds to the next process.

  In the process of S31, when there is no data for which the predetermined time has elapsed for the machine information data stored in the memory 69 (NO in S31), the process proceeds to the next process without deleting the data.

  Next, it is determined whether to read another two-dimensional barcode (S33). If another two-dimensional barcode is read (YES in S33), the process returns to S21, user settings for reading the other two-dimensional barcode are performed, and subsequent processing is performed. Further, in the process of S33, when no other two-dimensional barcode is read (NO in S33), the process is terminated.

  In the process of S22 described above, the mobile terminal 40 immediately acquires the position information by positioning using GPS or the like after reading the two-dimensional barcode, so that the position information of the mobile terminal 40 and the position information of the construction machine 10 are obtained. The deviation can be prevented.

  At this time, the date and time when the two-dimensional barcode is read and the date and time when the position information is acquired are acquired from the date and time acquisition unit 70 of the mobile terminal 40 and stored in the memory 69 together with the data of the machine information. It is also possible to confirm whether or not there is a difference between the position information and the position information of the construction machine 10 based on the difference in time.

  Further, the machine information in the processes shown in FIGS. 6 and 7 includes, for example, the machine calendar information of the construction machine as described above, and the machine calendar information includes, for example, engine system operation information, hydraulic system information, machine At least one information is included among setting information, fuel consumption information, and failure information.

  In the present embodiment, for example, a two-dimensional barcode may be displayed when maintenance is necessary. Further, in the present embodiment, the above-described processing procedure of only S27 to S32 may be separately provided as a data deletion processing procedure in the portable terminal 40.
