The storage unit 32 is a non-volatile storage unit such as an HDD, SSD, or flash memory that stores various information. For example, the storage unit 32 stores control programs such as a browser program and a message display program. Specifically, the browser program is a control program for causing the control unit 31 to execute communication processing with an external device such as the management server 20 according to a communication protocol such as HTTP (Hypertext Transfer Protocol). Also, the browser program may be a dedicated application for executing communication processing according to a predetermined communication protocol with the management server 20 .

The control unit 31 is a computer system that includes one or more processors and storage memory such as nonvolatile memory and RAM. The control unit 31 controls the operation of the communication terminal 30 by executing various processes according to the control program stored in the storage unit by the processor.

The control unit 31 functions as the various processing units by executing various processing according to the browser program and the message display program. Further, as another embodiment, part or all of the various processing units may be configured by electronic circuits.

The browser processing unit 311 can display a web page provided from the management server 20 via the communication network N1 on the operation display unit 33 and execute browser processing for inputting an operation for the operation display unit 33 to the management server 20. It is possible. That is, the communication terminal 30 functions as an operation terminal for the management server 20 by executing the browser program by the control unit 31 .

Specifically, in the communication terminal 30, when the user performs an operation to request access to a predetermined URL corresponding to the website of the support service provided by the management server 20, the browser processing unit 311 performs an operation. The website is displayed on the display unit 33 . The website is, for example, a site where the position information and the operation information of the work machine 10 are displayed. Further, in the communication terminal 30, when the control unit 31 receives a message from the management server 20 by e-mail or SNS, the message can be displayed.

[Notification control method]
In the management system 1, the control unit 161 of the work machine 10 and the control unit 21 of the management server 20 provide notification for restricting the output of the first notification information from the work machine 10 to the management server 20 as necessary. A control method is executed. Specifically, the notification control method includes outputting notification information (first notification information) when an event of a type preset in the work machine 10 occurs, and outputting the notification information after the output of the notification information. Restricting the output of the notification information according to the priority set in advance for the type of event corresponding to the notification information.

More specifically, in the notification control method described in this embodiment, as described below, when an event of a type preset for the work machine 10 occurs, the control unit 161 of the work machine 10 The first notification information is output to the management server 20 . Then, after the first notification information is output, the control unit 21 of the management server 20 restricts the output of the first notification information according to the priority of the event type corresponding to the first notification information. output to the work machine 10 a restriction instruction for After that, when receiving the restriction instruction, the control unit 161 of the work machine 10 restricts the output of the first notification information corresponding to the event type corresponding to the restriction instruction. Further, the control unit 161 sets a restriction period for restricting the output of the first notification information according to the priority, and cancels the restriction on the output of the first notification information after the expiration of the restriction period.

An example of notification control processing and management control processing executed by the control unit 161 and the control unit 21 to realize the notification control method will be described below. The present invention may be regarded as an invention of a notification control method in which the control unit 161 or the control unit 21 executes part or all of the notification control process and the management control process. Alternatively, it may be regarded as an invention of a management program for causing the control unit 161 or the control unit 21 to execute all of them. Each of the notification control process and the management control process may be executed by one or more processors.

[Notification control processing of communication device 16]
First, an example of notification control processing executed by the control unit 161 of each work machine 10 will be described with reference to FIG. 7 . For example, the notification control process is started by the control unit 161 when the engine 121 of the work machine 10 is turned on, and is repeatedly executed at predetermined time intervals such as 0.1 second intervals or 1 second intervals. be done. After that, the notification control process ends when the engine 121 is turned off. Further, the notification control process may be started in response to a predetermined user operation on work machine 10 or communication device 16 . Note that the notification control process may be executed by the control unit 11 .

<Step S1>
In step S<b>1 , the acquisition processing unit 172 of the control unit 161 executes information acquisition processing for acquiring the position information and the operation information of the work machine 10 . Specifically, the acquisition processing unit 172 acquires the position information from the position detection unit 163, and acquires the operation information from the control unit 11, the travel device 12, the work device 13, and the like. Further, the acquisition processing unit 172 acquires time information indicating the time when the position information and the operation information are acquired from the clock processing unit 171, associates the time information with the position information and the operation information, and outputs the information to the control unit. 161 RAM or the like. Further, the acquisition processing unit 172 receives the position information actively transmitted from the position detection unit 163, and receives the operation information actively transmitted from the control unit 11, the travel device 12, the working device 13, and the like. The position information and the operation information may be acquired by doing so.

<Step S2>
In step S2, control unit 161 determines whether or not engine 121 of work machine 10 is off. Specifically, the control unit 161 turns on the engine 121 of the work machine 10 when the engine drive switching unit 14 is turned on, and turns off the engine 121 of the work machine 10 when the engine drive switching unit 14 is turned off. We judge that it is. Then, if it is determined that the engine 121 of the work machine 10 is off (S2: Yes), the process proceeds to step S201, and if the engine 121 of the work machine 10 is not off (S2: No), the process proceeds to step S201. Move to step S3.

<Step S3>
If the engine 121 is not turned off, in subsequent step S3, the acquisition processing unit 172 of the control unit 161 stores the position information, the operation information, and the time information acquired in step S1 in the storage unit 162. Recorded in the management information D13. At this time, the control unit 161 may record only the information of the preset recording target items among the operation information temporarily recorded in the RAM in step S1 in the management information D13 as the operation information.

<Step S201>
On the other hand, when the engine 121 is off, in step S201, the output processing unit 173 of the control unit 161 transmits the management information D13 recorded in the storage unit 162 to the management server 20, and terminates the notification control processing. . Note that the management server 20 transmits a reception confirmation signal to the control unit 161 when receiving the management information D13 from the control unit 161 . Then, upon receiving the reception confirmation signal of the management information D13 from the management server 20 , the control section 161 deletes the management information D13 from the storage section 162 .

<Step S4>
In step S<b>4 , output processing unit 173 of control unit 161 determines whether or not an event of a type preset as a notification target has occurred in work machine 10 . For example, the event type to be notified is an event type registered in advance in the event information D11. Then, the output processing unit 173 determines that the event to be notified has occurred when the abnormality information regarding the type of the event to be notified is received from the control unit 11, the traveling device 12, the work device 13, and the like. Note that the output processing unit 173 may determine whether an event has occurred based on the operation information acquired in step S1. If it is determined that an event to be notified has occurred (S4: Yes), the process proceeds to step S5, and if it is determined that an event to be notified has not occurred (S4: No), the process proceeds to step S5. The process proceeds to step S7.

<Step S5>
In step S5, the restriction processing unit 174 of the control unit 161 determines whether or not the output restriction of the first notification information is set for the event type determined to have occurred in step S4. Specifically, when the restriction flag is set to ON for the event type in the event information D11, the restriction processing unit 174 sets the output restriction of the first notification information for the event type. I judge. The limit flag is set to ON in step S8, which will be described later.

Then, when the restriction processing unit 174 determines that the output restriction is set (S5: Yes), the process proceeds to step S7. That is, the restriction processing unit 174 restricts execution of the output processing of the first notification information in step S6 when the output restriction is set. That is, in the present embodiment, the output of the first notification information is executed for the first time with respect to the type of event that is the target of the output restriction, but the first notification information is output twice or more within the restriction period. Output will be restricted. As a result, the output of the first notification information can be restricted as necessary, and the amount or frequency of data communication between the work machine 10 and the management server 20 can be suppressed. Further, when it is determined that the output limit is not set (S5: No), the process proceeds to step S6.

<Step S6>
In step S6, the output processing unit 173 of the control unit 161 outputs first notification information including the type of event determined to have occurred in step S4, the time of occurrence of the event, and the machine identification information of the work machine 10. is executed to notify the management server 20 of the first notification process. Thereby, the control unit 21 of the management server 20 can recognize the occurrence of the event in the work machine 10 . The output processing section 173 when executing the output processing in step S6 is an example of the first output processing section according to the present invention.

<Step S7>
In step S<b>7 , the restriction processing unit 174 of the control unit 161 determines whether or not a restriction instruction has been received from the management server 20 . As described above, the restriction instruction includes the type of event to be restricted and information on the priority of the event type. Here, if it is determined that the restriction instruction has been received (S7: Yes), the process proceeds to step S8, and if it is determined that the restriction instruction has not been received (S7: No), the process proceeds to step S8. Go to S10.

<Step S8>
In step S8, the restriction processing unit 174 of the control unit 161 sets the output restriction of the first notification information for the event type specified by the restriction instruction based on the restriction instruction. Specifically, in the event information D11, the restriction processing unit 174 sets to ON the restriction flag corresponding to the type of event to be restricted specified by the restriction instruction.

<Step S9>
In step S9, the restriction processing unit 174 sets the restriction period corresponding to the priority based on the priority corresponding to the event type indicated by the restriction instruction and the restriction period information D12, The clock processing unit 171 is caused to start clocking the limited period. For example, when the priority is "medium", the restricted period is set to 1 hour, and when the priority is "low", the restricted period is set to 24 hours. Then, the timer processing unit 171 starts timer processing such as countdown or countup for determining the elapse of the limit period.

<Step S10>
In step S10, the restriction processing unit 174 of the control unit 161 determines whether or not the restriction period has passed for any of the event types. Here, if it is determined that the restricted period has passed for any of the event types (S10: Yes), the process proceeds to step S11, and if it is determined that the restricted period has not passed ( S10: No), the process returns to step S1. Note that the method of the restriction processing unit 174 is not limited to this as long as it can determine the elapse of the restriction period. For example, the restriction processing unit 174 sets the time after the restriction period has elapsed from the current time as the restriction release time, and when the current time clocked by the clock processing unit 171 reaches the restriction release time, the restriction period ends. may be considered to have passed.

<Step S11>
In step S11, the restriction processing unit 174 of the control unit 161 cancels the output restriction of the first notification information for the event type for which the restriction period has passed in step S10. Specifically, the restriction processing unit 174 sets off the restriction flag corresponding to the event type in the event information D11. As a result, when step S5 is executed next time, it is determined that the output limitation is not set for the event type.

[Management control processing of management server 20]
Next, an example of management control processing executed by the control unit 21 of the management server 20 will be described with reference to FIG. For example, the management control process is started by the control unit 21 when the power of the management server 20 is turned on, or when a predetermined user operation on the operation display unit 23 is performed. It should be noted that the control unit 21 can execute the management control process for each of the work machines 10 in parallel.

<Step S21>
In step S<b>21 , the output processing unit 212 of the control unit 21 determines whether or not an event has occurred in the working machine 10 . Specifically, when receiving the first notification information from the communication device 16 of the work machine 10, the output processing unit 212 determines that an event of the type indicated by the first notification information has occurred. When it is determined that the event has occurred (S21: Yes), the process proceeds to step S22. Wait in S21.

<Step S22>
In step S22, the output processing unit 212 of the control unit 21 transmits the second notification information including various kinds of information preset to correspond to the event to a communication owned by a user of the working machine 10 or a service person. The terminal 30 is notified. Specifically, the second notification information includes machine identification information of the work machine 10 in which the event has occurred, the type of the event, the time of occurrence of the event, response information for responding to the event, and the like. . The correspondence information includes, for example, contact information of the user of the work machine 10, history of past events of the work machine 10, action information for recovering the event, and the like. As described above, the second notification information is sent to a preset destination corresponding to the user or service person using e-mail, SNS, or the like. The output processing section 212 when executing the output processing of step S22 is an example of the second output processing section according to the present invention.

<Step S23>
In step S23, the restriction processing unit 213 of the control unit 21 determines whether or not the type of event determined to have occurred in step S21 is subject to restriction. Specifically, when the priority corresponding to the event type set in the priority information D21 corresponds to either "medium" or "low", the restriction processing unit 213 determines that the event falls under the restriction target. to decide. Here, if it is determined that it is subject to the restriction (S23: Yes), the process proceeds to step S24, and if it is determined that it is not subject to the restriction (S23: No), the process returns to step S21. .

<Step S24>
In step S24, the restriction processing unit 213 of the control unit 21 issues a restriction instruction for restricting the output of the first notification information corresponding to the event type determined to have occurred in step S21. The information is sent to the work machine 10 that sent the information, and the process returns to step S21. That is, after the first notification information is output, the restriction processing unit 213 restricts the output of the first notification information according to the priority of the event type corresponding to the first notification information. The restriction instruction includes the type of the event determined to be subject to restriction in step S23, the priority corresponding to the type of the event, and the like. Accordingly, as described above, in work machine 10, restriction processing unit 174 of control unit 161 restricts the output of the first notification information for the type of event specified by the restriction instruction.

As described above, in the management system 1 according to the present embodiment, after an event occurs in the work machine 10 and the first notification information is output, if an event of the same type occurs, the first notification information is output. The output of notification information is restricted as necessary. As a result, the amount or frequency of data communication between the work machine 10 and the management server 20 can be reduced as needed. Furthermore, when the output of the first notification information is restricted, the output of the second notification information from the management server 20 to the communication terminal 30 is also suppressed at the same time. The communication volume or communication frequency of data communication between is also suppressed.

In addition, in the management system 1, the management server 20 manages priority information D21 in which event types and priorities are associated with each other. Therefore, when the priority information D21 is changed by the management server 20, for the plurality of work machines 10 managed by the management server 20, the content of the change in the priority information D21 is reflected and the first notification information is output. restrictions are enforced. Therefore, compared to the case where the priority information D21 is stored in each of the work machines 10, management such as setting or changing the correspondence relationship between the event type and the priority in the priority information D21 is easier. Furthermore, if the priority information D21 managed by the management server 20 contains a mixed relationship between the types of events that can occur in a plurality of models of work machines 10 and their priorities, the priority information may be different for each model. There is no need to manage the priority information D21, and it is not necessary to prepare the priority information D21 for each work machine 10 according to the model of the work machine 10 concerned.

Note that in the present embodiment, the output of the first notification information is executed for the first time and the second and subsequent outputs of the first notification information are restricted for the type of event that is subject to output restriction. was described as an example. On the other hand, the number of outputs until the output of the first notification information is limited is not limited to one. That is, as another embodiment, the restriction on the output of the first notification information is such that when the event of the same type occurs a specific number of times within a specific period, the first notification information corresponding to the event type is may be executed. For example, the specific period is a preset period such as 10 minutes, 1 hour, 1 day, or 1 week, and the specific number of times is a preset number of times such as 2 times or 3 times or more. In addition, this point is the same in a second embodiment and a third embodiment, which will be described later.

[Second embodiment]
In the first embodiment, the case where the priority information D21 is managed by the management server 20 has been described. Hereinafter, in the second embodiment, a case where the priority information D21 is managed by each work machine 10 in the management system 1 will be described. It should be noted that the description of the configuration and processing of this embodiment that are the same as those of the first embodiment will be omitted.

In this embodiment, the priority information D21 is stored in the storage unit 22 of the management server 20 and is also stored in the storage unit 162 of the communication device 16 of the work machine 10. The priority information D21 may be stored not only in the storage unit 162 but also in a data server (not shown) that can communicate with the communication device 16 as long as the control unit 161 can access it.

Then, the control unit 161 of the work machine 10 executes the notification control process shown in FIG. 9 instead of the notification control process shown in FIG. Also, the control unit 21 of the management server 20 executes the management control process shown in FIG. 10 instead of the management control process shown in FIG. Specifically, as shown in FIG. 9, in the notification control process according to the present embodiment, after execution of step S6, the restriction processing unit 174 of the control unit 161 performs Step S71 is executed. If it is determined in step S4 that no event has occurred (S4: No), or if it is determined in step S5 that there is a limit setting (S5: Yes), the process proceeds to step S10.

<Step S71>
In step S71, the restriction processing unit 174 of the control unit 161 determines whether or not the type of event determined to have occurred in step S4 corresponds to a restriction target. Specifically, based on the priority information D21 stored in the storage unit 162, the restriction processing unit 174 identifies the priority of the event type determined to have occurred in step S4. Then, when it is determined that the type of the event is subject to restriction when the priority is "medium" or "low" (S71: Yes), determining to restrict the output of the first notification information, The process proceeds to step S8 to execute limit setting. That is, after the first notification information is output, the restriction processing unit 174 restricts the output of the first notification information according to the priority of the event type corresponding to the first notification information.

On the other hand, as shown in FIG. 10, in the management control process according to the present embodiment, the restriction processing unit 213 of the control unit 21 executes steps S231 and S241 instead of steps S23 and S24 (see FIG. 8). .

<Step S231>
In step S231, the restriction processing unit 213 determines whether or not the priority information D21 stored in the storage unit 22 has been changed. For example, the restriction processing unit 213 can change the content of the priority information D21 according to user's operation. Here, if it is determined that the priority information D21 has been changed (S231: Yes), the process proceeds to step S241, and if it is determined that the priority information D21 has not been changed (S231: No), the process goes to step S21.

<Step S241>
In step S<b>241 , the restriction processing unit 213 transmits the priority information D<b>21 determined to have been changed in step S<b>231 to the communication device 16 of each work machine 10 . As a result, in the communication device 16 of the work machine 10, the restriction processing unit 174 of the control unit 161 changes the priority information D21 stored in the storage unit 162 based on the priority information D21 received from the management server 20. do. That is, in the management system 1 according to this embodiment, the priority information D21 of the work machine 10 is synchronized with the priority information D21 of the management server 20. FIG. Note that the transmission timing of the priority information D21 to each work machine 10 may be other timing such as the timing when the engine 121 of the work machine 10 is turned on.

Further, in the management server 20, the storage unit 22 may store priority information D21 corresponding to each model of the work machine 10. In this case, when the priority information D21 of a specific model is changed by a user operation or the like, the control unit 21 assigns the post-change priority information D21 to the work machine 10 of the specific model corresponding to the priority information D21. Send.

In addition, the storage unit 22 may store common priority information D21 corresponding to a plurality of models of work machines 10 . In this case, when the priority information D21 is changed by a user's operation or the like, the control unit 21 transmits the changed priority information D21 to each of the work machines 10 regardless of the model.

As described above, in the management system 1 according to the present embodiment, the control unit 161 of each work machine 10 determines whether or not there is a restriction on the output of the first notification information, thereby reducing the processing load on the management server 20. be done.

[Third Embodiment]
In the first embodiment and the second embodiment, the output limitation of the first notification information output from the work machine 10 to the management server 20 has been described. Hereinafter, in the third embodiment, a configuration in which the management system 1 restricts the output of the second notification information output from the management server 20 to the communication terminal 30 as necessary will be described.

Specifically, in the notification control method according to the present embodiment, the control unit 161 of the work machine 10 transmits the first notification information to the management server 20 when an event of a type preset for the work machine 10 occurs. Output. Then, the control unit 21 of the management server 20 outputs the second notification information to the communication terminal 30 when receiving the first notification information. Then, after the second notification information is output, the control unit 21 restricts the output of the second notification information according to the priority of the event type corresponding to the second notification information. It should be noted that the description of the configuration and processing of this embodiment that are the same as those of the first embodiment will be omitted. Also, the management system 1 may be configured by selecting the configurations of the first to third embodiments.

In this embodiment, the event information D11 and the limited period information D12 are stored in the storage unit 22 of the management server 20. In the event information D11 stored in the storage unit 22, a limitation flag and priority are set for the output limitation of the second notification information. Then, the control unit 21 of the management server 20 executes the management control process shown in FIG. 11 instead of the management control process shown in FIG.

As shown in FIG. 11, in the management control process according to this embodiment, the restriction processing unit 213 of the control unit 21 executes steps S31 to S35 instead of step S24 (see FIG. 8).

<Step S31>
When it is determined in step S21 that an event has occurred (S21: Yes), in subsequent step S31, the restriction processing unit 213 performs the second notification regarding the type of event determined to have occurred in step S21. Determines whether or not an information output limit is set. Specifically, when the restriction flag for the type of the event is set to ON in the event information D11 stored in the storage unit 22, the restriction processing unit 213 sets the second notification information for the type of the event. output limit is set. The restriction flag is set to ON in step S32, which will be described later.

Then, when it is determined that the output limit is set (S31: Yes), the process proceeds to step S34 without executing step S22. That is, the restriction processing unit 174 restricts execution of the output processing of the second notification information in step S22 when the output restriction is set. Further, when it is determined that the output limit is not set (S31: No), the process proceeds to step S22.

<Step S32>
If it is determined in step S23 that it is subject to restriction (S23: Yes), in subsequent step S32, the restriction processing unit 213 sets the output restriction of the second notification information for the event type. Specifically, the restriction processing unit 213 sets ON the restriction flag corresponding to the type of event to be restricted in the event information D11. That is, after the second notification information is output, the restriction processing unit 213 restricts the output of the second notification information according to the priority of the event type corresponding to the second notification information.

In addition, in the configuration in which the output of the second notification information is restricted as necessary as in the present embodiment, the output of the first notification information is further restricted as in the first embodiment or the second embodiment. It may be restricted as necessary. In this case, the conditions regarding the output restriction of the first notification information and the second notification information may be different. For example, the second and subsequent output of the first notification information is restricted when the priority of the event type corresponding to the first notification information is "low", and the second and subsequent output of the second notification information is It is conceivable that the output is restricted when the priority of the event type corresponding to the second notification information is "middle". As a result, from the work machine 10 to the management server 20, the second and subsequent outputs of only the first notification information of the event type with the priority "low" are restricted, and the management server 20 to the communication terminal 30 , the second and subsequent outputs of the first notification information of the type of event with the priority of "middle" or "low" are restricted. Further, the contents of the limited period information D12 may differ between the output limitation of the first notification information and the output limitation of the second notification information. For example, in the output restriction of the first notification information, the restriction period corresponding to the priority "medium" is "1 hour", and the restriction period corresponding to the priority "low" is "24 hours". and in the output limitation of the second notification information, the limitation period corresponding to the priority "medium" is "3 hours", and the limitation period corresponding to the priority "low" is "48 hours". Something is possible. As a result, the period during which the output of the second notification information from the management server 20 to the communication terminal 30 is restricted can be made longer than the period during which the output of the first notification information from the work machine 10 to the management server 20 is restricted.

<Step S33>
In step S<b>33 , the restriction processing unit 213 sets the restriction period corresponding to the priority based on the priority corresponding to the event type and the restriction period information D<b>12 . Causes the timing of the period to begin. For example, when the priority is "medium", the restricted period is set to 1 hour, and when the priority is "low", the restricted period is set to 24 hours. Then, the timer processing unit 211 starts timer processing such as countdown or countup for determining the elapse of the limit period.

<Step S34>
In step S34, the restriction processing unit 213 of the control unit 21 determines whether or not the restriction period has passed for any of the event types. Here, if it is determined that the restricted period has passed for any of the event types (S34: Yes), the process proceeds to step S35, and if it is determined that the restricted period has not passed ( S34: No), the process returns to step S21. Note that the method of the restriction processing unit 213 is not limited to this as long as it can determine the elapse of the restriction period. For example, the restriction processing unit 213 sets the time after the restriction period has elapsed from the current time as the restriction release time, and when the current time clocked by the clock processing unit 211 reaches the restriction release time, the restriction period ends. may be considered to have passed.

<Step S35>
In step S35, the restriction processing unit 213 of the control unit 21 cancels the output restriction of the second notification information for the type of event for which the restriction period has passed in step S34. Specifically, the restriction processing unit 213 sets off the restriction flag corresponding to the event type in the event information D11. As a result, when step S31 is executed next time, it is determined that the output limit is not set for the event type.

As described above, in the management system 1 according to the present embodiment, after an event occurs in the work machine 10 and the second notification information is output, if an event of the same type occurs, the second notification information is output. The output of notification information is restricted as necessary. As a result, the communication volume or communication frequency of data communication between the management server 20 and the communication terminal 30 can be suppressed.
