Description

  The present invention relates to a theft monitoring system for monitoring the theft of work vehicles.

  The theft monitoring system as described above monitors the theft of a work vehicle such as a farm vehicle, and when the engine is started within the theft alarm setting time, an alarm is given as if there was a theft ( For example, see Patent Document 1.)

  In the system described in Patent Document 1, the burglar alarm setting time is set to a time when work is not performed on the work vehicle, such as early morning or night. And since the engine of the work vehicle is not normally started within the theft alarm setting time, the engine is started within the theft alarm setting time, so that an alarm is given for theft.

JP 2008-222179 A

  In the system described in Patent Document 1, an alarm is issued by starting the engine within the burglar alarm setting time, so that an alarm is erroneously performed even when the user is working on a work vehicle. Sometimes. For example, depending on the work situation, you may want to start work earlier than usual. In this case, the engine of the work vehicle will be started within the theft alarm setting time such as early morning, even though it is not theft. You will be alerted. In some cases, the work may be extended until the time of setting the theft alarm at night or the like, and at this time, the alarm is issued even though it is not theft.

  By the way, when working in the early morning or at night, the operator can change the setting time of the theft alarm to exclude early morning or night, etc. It is possible to prevent the problem of end. However, there is a possibility that the operator may forget to operate, and every time work is performed early in the morning or at night, an operation for changing the setting time of the theft alarm must be performed, which places a heavy burden on the operator. It will end up.

  In view of this situation, the main problem of the present invention is that it is possible to monitor the theft of a work vehicle while preventing the alarm from being issued even though it is not theft without placing a heavy burden on the worker. The point is to provide a theft monitoring system.

The first characteristic configuration of the present invention includes a work time zone setting unit capable of freely setting a work time zone,
A time detector for detecting the operation start time and operation end time of the work vehicle;
The operation time zone from the operation start time to the operation end time detected by the time detection unit and the work time zone set by the work time zone setting unit are overlapped or non-overlapping. A determination unit for determining whether or not
When it is determined that the non-overlapping state is determined by the determination unit, the work vehicle is stolen, and when the determination unit is determined to be the overlapping state, the work vehicle is stolen. There exists in the point provided with the alerting | reporting part which does not alert | report.

  According to this configuration, for example, when work is started earlier than usual, the operation end time is later than the start time of the work time period, so that the work time period and the operation time period overlap. Become. Therefore, it will determine with a determination part being an overlapping state, and alerting | reporting by an alerting | reporting part will not be performed. When the work is extended more than usual, the operation start time is before the end time of the work time period, so that the work time period and the operation time period overlap. Therefore, it will determine with a determination part being an overlapping state, and alerting | reporting by an alerting | reporting part will not be performed. In this way, even when the work is started earlier than usual or when the work is extended more than usual, notification by the notification unit is not performed, and it is prevented from being alarmed even though it is not theft. Can do.

  On the other hand, if the operation starts and ends within a time zone other than the work time zone, the work time zone and the operation time zone will not overlap, and the determination unit determines that the non-overlapping state exists, When the theft has occurred, the notification unit can notify the theft of the work vehicle.

  In this way, the determination unit determines whether it is an overlapping state or a non-overlapping state in which the work time zone and the operation time zone overlap, and whether to perform notification by the notification unit according to the determination result of the determination unit. By deciding, it is possible to monitor the theft of the work vehicle while preventing a warning even though it is not theft without placing a new burden on the worker.

The second characteristic configuration of the present invention includes a work time zone setting unit capable of freely setting a work time zone,
A time detector for detecting the operation start time and operation end time of the work vehicle;
A first state in which the operation start time detected by the time detection unit is before the work time zone set by the work time zone setting unit, and the operation end time detected by the time detection unit A determination unit that determines a second state after the work time zone set by the work time zone setting unit;
When the determination unit determines the first state or the second state, a notification unit that notifies the work vehicle of theft;
A notification section by the notification section, a selection section that can be freely selected from a plurality of notification forms,
A position information acquisition unit for acquiring position information of the work vehicle;
A distance information detection unit that detects distance information to the position information of the work vehicle with respect to a reference point based on the position information of the work vehicle acquired by the position information acquisition unit;
The said selection part exists in the point comprised so that the selection from a some alerting | reporting form may be performed according to the distance information detected by the said distance information detection part.

  According to this configuration, the selection unit can select the notification mode by the notification unit from a plurality of notification modes. Therefore, the selection unit does not always report the theft of the work vehicle in one notification mode. The theft of the work vehicle can be notified in a notification form selected from a plurality of notification forms having different levels.

  In the first state where the operation start time is before the work time zone and the second state where the operation end time is after the work time zone, for example, from the reference point to the position information of the work vehicle. Since it is assumed that the possibility of theft of the work vehicle increases as the distance increases, the selection unit sets the notification form by the notification unit according to the distance information detected by the distance information detection unit. You have selected from the form.

  Thereby, the selection unit can select a notification mode by the notification unit from a plurality of notification modes so as to increase the notification level as the distance information from the reference point to the position information of the work vehicle increases (as the distance information increases). it can. Therefore, for example, when the user moves the work vehicle slightly from the reference point for some reason, a notification mode with a low notification level can be selected, and the user is not stolen. It is possible to prevent excessive notification. In addition, the user recognizes the notification level of the notification mode by the notification unit, and understands the distance information from the reference point to the position information of the work vehicle and the possibility of the work vehicle being stolen. It is also possible to take appropriate measures against theft of the work vehicle.

A third characteristic configuration of the present invention is a selection unit that can select a notification mode by the notification unit from a plurality of notification modes;
An operation information acquisition unit for acquiring operation information of an operator for the work vehicle;
Based on the operation information acquired by the operation information acquisition unit, an operation pattern creation unit that creates a normal operation pattern,
A comparison unit that compares the operation information acquired by the operation information acquisition unit with the normal operation pattern when performing notification by the notification unit;
The said selection part exists in the point comprised so that the selection from a some alerting | reporting form may be performed according to the comparison result by the said comparison part.

  According to this configuration, since the operation pattern generation unit creates a normal operation pattern based on the operation information acquired by the operation information acquisition unit, the normal operation pattern is used when the worker drives the work vehicle. The operation pattern indicating what kind of operation is performed is shown in FIG. The comparison unit grasps how much the operation information differs from the normal operation pattern by comparing the operation information acquired by the operation information acquisition unit with the normal operation pattern when performing notification by the notification unit. can do.

  Since the operation pattern when driving the work vehicle varies from person to person, grasp whether the work vehicle is operated by an operator or a person other than the operator from the comparison result of the comparison unit Can do. Therefore, the selection unit is assumed to be an operator who is operating the work vehicle, for example, by selecting a notification mode by the notification unit from a plurality of notification modes according to the comparison result by the comparison unit. The notification mode at the time and the notification mode when it is assumed that a person other than the operator is operating the work vehicle can be changed. Therefore, when the possibility of the theft of the work vehicle is high, the notification mode of the notification level corresponding to the work vehicle can be selected, and when the possibility of the theft of the work vehicle is low, the notification of the notification level corresponding to the notification level. The form can be selected, and the theft of the work vehicle can be notified in an appropriate notification form.

The fourth characteristic configuration of the present invention includes an artificially operated selection condition input unit capable of freely inputting a selection condition when performing the selection by the selection unit,
The said selection part exists in the point comprised so that the selection from a some alerting | reporting form may be performed based on the selection conditions input in the said selection condition input part.

  According to this configuration, the operator can input the selection condition by operating the selection condition input unit, and the selection unit is configured by the notification unit from a plurality of notification forms based on the input selection condition. A notification form can be selected. Thereby, it is possible for the operator to select in which notification form the vehicle vehicle theft is to be notified.

Not only this single positioning but also DGPS (differential GPS positioning) that acquires position information of the work vehicle 10 in consideration of information at a reference station arranged at a predetermined reference point in addition to a signal from the positioning satellite 2 ), RTK positioning (real-time kinematic positioning) and the like can be applied, and the position information of the work vehicle 10 can be obtained by various positioning methods.

  The work time zone setting unit 12 is configured to set a work time zone in which work is performed on the work vehicle 10 in one day. The work time zone setting unit 12 is configured to be manually operated, and the operator can set the work time zone by operating the work time zone setting unit 12. Similar to the work time zone setting unit 12, the mobile terminal 30 also includes a work time zone setting unit 31.

  The time detection unit 13 is configured to detect an operation start time and an operation end time of the work vehicle 10. Although illustration is omitted, the work vehicle 10 is provided with a sensor capable of detecting the operation start state, a sensor capable of detecting the operation end state, and the like. The time detection unit 13 detects detection information of these sensors. The time when the operation start state is detected is detected as the operation start time of the work vehicle 10, and the time when the operation end state is detected is detected as the operation end time. As a sensor for detecting the operation start state, for example, a sensor for detecting the start of the engine by a key of the work vehicle 10, a sensor for detecting that the door of the control unit has been opened or closed at the start of work, and the like are applicable. As a sensor for detecting the operation end state, for example, a sensor for detecting stop of the engine by a key of the work vehicle 10, a sensor for detecting that the door of the control unit is opened or closed at the end of work, and the like can be applied.

  The operation information acquisition unit 15 is configured to acquire operator operation information for the work vehicle 10. Although illustration is omitted, the work vehicle 10 is provided with a sensor or the like that can detect the operation state of the operator with respect to the work vehicle 10, and the operation information acquisition unit 15 is based on the detection information of those sensors. Operation information indicating what operation is performed on the work vehicle 10 is obtained. For example, the operation information is information indicating the number of shift stages in the transmission when the work vehicle 10 is traveled, the number of brake or clutch operations when the work vehicle 10 is traveled, and the like.

  The warning unit 16 is configured to perform a warning operation with a warning buzzer or the like when the notification unit 22 of the management device 20 notifies the theft of the work vehicle 10. The selection condition input unit 17 is configured to be able to input a selection condition when the selection unit 23 of the management device 20 selects a notification form of the notification unit 22. The selection condition input unit 17 is configured as an artificial operation type, and the operator can input the selection condition by operating the selection condition input unit 17.

  The determination unit 21 is configured to determine whether the operation time zone and the work time zone are in an overlapping state or a non-overlapping state. The operation time zone is a time zone from the operation start time detected by the time detection unit 13 of the work vehicle 10 to the operation end time. The work time zone is set by the work time zone setting units 12 and 31 of the work vehicle 10 and the portable terminal 30.

  The notification unit 22 notifies the theft of the work vehicle 10 when the determination unit 21 determines that it is in the non-overlapping state, and when the determination unit 21 determines that it is in the overlapping state, the work vehicle 10. It is configured so as not to notify theft.

  The operation pattern generation unit 24 is configured to generate a normal operation pattern based on the operation information acquired by the operation information acquisition unit 15 of the work vehicle 10. Since the operation information acquisition unit 15 acquires operation information indicating the number of shift stages in the transmission when the work vehicle 10 is traveled, the number of brake and clutch operations when the work vehicle 10 is traveled, operation pattern generation is performed. The unit 24 is a normal operation pattern such as how many shift stages the transmission device is set to, how many times the brake is operated, how many times the clutch is operated, etc., when the worker travels the work vehicle 10. Is configured to generate As a result, the normal operation pattern indicates an operation tendency of what operation is performed when the worker travels the work vehicle 10.

  The comparison unit 25 compares the operation information acquired by the operation information acquisition unit 15 of the work vehicle 10 with the normal operation pattern generated by the operation pattern generation unit 24 when performing notification by the notification unit 22. It is configured. The comparison unit 25 uses the operation information acquired by the operation information acquisition unit 15 when the determination unit 21 determines the non-overlapping state, and compares the operation information with a normal operation pattern. For example, the comparison unit 25 is configured to obtain a degree of difference indicating how much the acquired operation information differs from a normal operation pattern. For example, the comparison unit 25 determines whether or not the number of gears in the transmission acquired during notification by the notification unit 22 is different from the number of gears in the normal operation pattern transmission. Accordingly, the degree of difference can be obtained. Further, the comparison unit 25 determines whether or not the acquired number of brake and clutch operations is out of the allowable range with respect to the allowable range based on the number of brake and clutch operations in the normal operation pattern. In this case, the degree of difference can be obtained depending on how much the difference is.

  The selection part 23 is comprised so that selection of the alerting | reporting form by the alerting | reporting part 22 from several alerting | reporting forms is possible. As a notification form, for example, in addition to the first notification form in which a warning operation is performed by the warning unit 16 of the work vehicle 10 and the alarm operation, the occurrence of theft of the work vehicle 10 is notified to the portable terminal 30 by e-mail or the like. In addition to the second notification mode for notification and the notification by alarm operation and e-mail or the like, the third notification mode for notifying the worker of the occurrence of theft of the work vehicle 10 by telephone is set. This notification form is not limited to the three notification forms, and other notification forms can be applied, and what kind of notification form is included and how many notification forms are set can be appropriately changed.

  The mobile terminal 30 includes a work time zone setting unit 31, a display unit 32, a selection condition input unit 33, a mobile terminal communication device 34, and the like. The work time zone setting unit 31 and the selection condition input unit 33 are This is the same as that provided in the work vehicle 10 described above. The display unit 32 is configured to be able to display the content of notification by the notification unit 22 of the management device 20 and various types of information transmitted from the management device 20.

Hereinafter, the operation of the theft monitoring system 1 in the first embodiment will be described.
As shown in FIG. 3, first, the operator sets a work time zone by operating the work time zone setting units 12 and 31 of the work vehicle 10 or the portable terminal 30 (step # 1). Then, when the theft monitoring system 1 is turned on in the work vehicle 10 or the portable terminal 30, the time detection unit 13 detects the operation start time, and the time detection unit 13 detects the operation end time. (Steps # 2-4).

  The determination unit 21 determines whether the operation time zone and the work time zone from the operation start time to the operation end time are overlapped or non-overlapping (step # 5). If the determination unit 21 determines that there is a non-overlapping state, the notification unit 22 reports the theft of the work vehicle 10 (in the case of No in step # 5, step # 6). On the other hand, when the determination unit 21 determines that there is an overlapped state, the notification unit 22 does not notify the work vehicle 10 of theft (in the case of Yes in step # 5).

  In the first embodiment, it is determined whether or not to report the theft of the work vehicle 10 by the notification unit 22 depending on whether the operation time zone and the work time zone are overlapped or non-overlapping. ing. Therefore, based on FIG. 4, if the relationship between the operation time zone and the work time zone is any relationship, the notification unit 22 reports the theft of the work vehicle 10, and conversely, the operation time zone and the work time. The relationship between the belt and the band will be described as to whether the notification of the theft of the work vehicle 10 by the notification unit 22 is not performed.

  In the first embodiment, as shown in (1) of FIG. 4, if the operation start time T1 is before the work time zone and the operation end time T2 is also before the work time zone, The notifying unit 22 notifies the theft of the work vehicle 10 that the work time zone does not overlap and is in a non-overlapping state and the work vehicle 10 is stolen. As shown in (2) of FIG. 4, if the operation start time T1 is later than the work time zone and the operation end time T2 is later than the work time zone, the operation time zone and the work time zone are determined. It is assumed that the work vehicle 10 is stolen by the notification unit 22 assuming that the work vehicle 10 has been stolen without being overlapped.

  On the other hand, as shown in (3) of FIG. 4, if the operation start time T1 is before the work time zone and the operation end time T2 is within the work time zone, the operation time zone and the work time zone are determined. For example, assuming that the operation is started early, the notification unit 22 is not notified of the theft of the work vehicle 10. As shown in (4) of FIG. 4, if the operation start time T1 is within the work time zone and the operation end time T2 is later than the work time zone, the operation time zone and the work time zone overlap. For example, assuming that the work is extended, the notification unit 22 is not notified of the theft of the work vehicle 10.

  Further, as shown in FIG. 4 (5), if the operation start time T1 is before the work time zone and the operation end time T2 is after the work time zone, the operation time zone and the work time zone are determined. For example, it is assumed that the work is started early and the work is further extended, so that the notification of the theft of the work vehicle 10 by the notification unit 22 is not performed.

  As shown in (6) of FIG. 4, if the operation start time T1 is within the work time zone and the operation end time T2 is also within the work time zone, the operation time zone overlaps with the work time zone, Assuming that the work is being performed within the work time zone, the notification unit 22 is not notified of the theft of the work vehicle 10.

  Thus, by determining whether to report the theft of the work vehicle 10 by the notification unit 22 depending on whether the operation time zone and the work time zone are overlapping or non-overlapping states, Although the work vehicle 10 is not stolen, the theft of the work vehicle 10 can be monitored while preventing the notification of the theft of the work vehicle 10.

  Here, as described above, when the notifying unit 22 notifies the theft of the work vehicle 10, the selecting unit 23 uses a plurality of notification modes based on the selection conditions input by the selection condition input units 17 and 33. One notification form is selected. Thus, the operator can select the notification condition in which the theft of the work vehicle 10 is notified by the operator inputting the selection conditions using the selection condition input units 17 and 33.

  Moreover, the selection part 23 can also select the alerting | reporting form which alert | reports the theft of the work vehicle 10 in the alerting | reporting part 22 from several alerting | reporting forms according to the comparison result of the comparison part 25. FIG. The comparison unit 25 performs operation information and operation pattern generation unit 24 acquired by the operation information acquisition unit 15 of the work vehicle 10 when performing notification by the notification unit 22 (when the determination unit 21 determines a non-overlapping state). The degree of difference is obtained by comparing with the normal operation pattern generated in the above. Therefore, if the degree of difference is greater than or equal to the set value, the selection unit 23 increases the notification level because the operator is not driving the work vehicle 10 and the work vehicle 10 is likely to be stolen. One notification form is selected from a plurality of notification forms. Since the operation pattern when traveling the work vehicle 10 varies depending on the person, if the operation pattern is different from the normal operation pattern, it is highly probable that the work vehicle 10 is stolen, and the notification mode for raising the notification level is selected. Thus, the theft of the work vehicle 10 can be appropriately notified.

  As described above, the selection unit 23 can select the work vehicle 10 from the plurality of notification forms according to the selection conditions input by the selection condition input units 17 and 33 and the comparison result of the comparison unit 25. It is possible to select a notification form when notifying the theft. For example, the selection unit 23 temporarily selects one notification form from a plurality of notification forms based on the selection condition input by the selection condition input unit 33. And if the difference degree which is the comparison result of the comparison part 25 is more than a setting value, the selection part 23 will fully select the alerting | reporting form different from the temporarily selected alerting | reporting form so that an alerting | reporting level may be raised.

  As described above, when the first notification form, the second notification form, and the third notification form are set as the notification form, the first condition is the condition for selecting the first notification form. A notification form is temporarily selected. If the degree of difference as the comparison result of the comparison unit 25 is less than the set value, the first notification form of the temporary selection is selected as it is, and if the degree of difference as the comparison result of the comparison unit 25 is equal to or greater than the set value. In order to increase the notification level, it is possible to change from the first notification form of provisional selection to the second notification form and perform this selection.

[Second Embodiment]
In the second embodiment, the determination content of the determination unit 21 and the selection content of the notification form by the selection unit 23 are different from those of the first embodiment, so the difference will be mainly described, and the other configurations will be described. Is omitted.

  In the second embodiment, the determination unit 21 has a first state in which the operation start time detected by the time detection unit 13 is before the work time zone set by the work time zone setting units 12 and 31, and the time The operation end time detected by the detection unit 13 is configured to determine a second state after the work time zone set by the work time zone setting units 12 and 31. And the alerting | reporting part 22 is comprised so that the theft of the work vehicle 10 may be alert | reported, when the determination part 21 determines with a 1st state or a 2nd state.

Hereinafter, the operation of the theft monitoring system 1 in the second embodiment will be described.
As shown in FIG. 5, first, the operator sets the work time zone by operating the work time zone setting units 12 and 31 of the work vehicle 10 or the portable terminal 30 (step # 11). Then, when the theft monitoring system 1 is turned on in the work vehicle 10 or the portable terminal 30, the time detection unit 13 detects the operation start time and determines whether the determination unit 21 is in the first state. (Steps # 12 to 14).

  If the determination unit 21 determines that the state is the first state, the notification unit 22 notifies the work vehicle 10 of theft (in the case of Yes in step # 14, step # 17). If the determination unit 21 determines that the state is not the first state, the time detection unit 13 detects the operation end time, and determines whether or not the determination unit 21 is in the second state (step # 14). In the case of No in step # 15, 16).

  When the determination unit 21 determines that the state is the second state, the notification unit 22 notifies the work vehicle 10 of theft (in the case of Yes in step # 16, step # 17). Conversely, if the determination unit 21 determines that the state is the second state, the notification unit 22 does not notify the theft of the work vehicle 10 (in the case of No in step # 16).

  In the second embodiment, whether to notify the theft of the work vehicle 10 by the notification unit 22 is determined depending on whether the state is the first state or the second state. Therefore, based on FIG. 4, in any case, the notification unit 22 reports the theft of the work vehicle 10, and conversely, in any case, the notification unit 22 reports the theft of the work vehicle 10. Explain if there is.

  In the second embodiment, as shown in (1) of FIG. 4, if the operation start time T1 is before the work time zone and the operation end time T2 is also before the work time zone, the first state is set. Assuming that the work vehicle 10 has been stolen, the notification unit 22 reports the theft of the work vehicle 10. As shown in (2) of FIG. 4, if the operation start time T1 is later than the work time zone and the operation end time T2 is later than the work time zone, the second state is established and the work vehicle 10 is stolen. If it has occurred, the notification unit 22 notifies the theft of the work vehicle 10.

  As shown in (3) of FIG. 4, if the operation start time T1 is before the work time zone and the operation end time T2 is within the work time zone, the first state is entered, and the work vehicle 10 is stolen. As a result, the notification of the theft of the work vehicle 10 by the notification unit 22 is performed. As shown in (4) of FIG. 4, if the operation start time T1 is within the work time zone and the operation end time T2 is later than the work time zone, the second state occurs, and the work vehicle 10 is stolen. As a result, the notification of the theft of the work vehicle 10 by the notification unit 22 is performed.

  Further, as shown in FIG. 4 (5), if the operation start time T1 is before the work time zone and the operation end time T2 is after the work time zone, the first state and the second state are obtained. Assuming that the work vehicle 10 has been stolen, the notification unit 22 reports the theft of the work vehicle 10.

  On the other hand, as shown in FIG. 4 (6), if the operation start time T1 is within the work time zone and the operation end time T2 is also within the work time zone, it is neither the first state nor the second state. Assuming that the work is performed within the work time zone, the notification of the theft of the work vehicle 10 by the notification unit 22 is not performed.

  When notifying the theft of the work vehicle 10 by the notification unit 22, the selection unit 23 selects one of a plurality of notification forms according to the distance information detected by the distance information detection unit 26, as shown in FIG. The notification form is selected. The distance information detection unit 26 is provided in the management device 20, and based on the position information of the work vehicle 10 acquired by the position information acquisition unit 14 of the work vehicle 10, up to the position information of the work vehicle 10 with respect to the reference point. It is configured to detect distance information. For example, the distance information detection unit 26 uses the worker's home or the like as the reference point K as shown in FIG. Then, the distance information detection unit 26 determines whether the distance information to the position information of the work vehicle 10 with respect to the reference point K is within the range of the distance R1, the distance R1 or more and the range of the distance R2. It is detected whether it is greater than or equal to R2 and within the range of distance R3 or outside the range of distance R3.

  Here, for example, in addition to the first to third notification modes described above, the selection unit 23 transmits, for example, a warning message for theft of the work vehicle 10 to the portable terminal 30 as a plurality of notification modes, A notification form for alerting such as displaying the contents for alerting theft on the display unit of the work vehicle 10 is also selectable.

  As illustrated in FIG. 6, the selection unit 23 determines that the notification level is lower than the notification level 1 when the distance information detected by the distance information detection unit 26 is distance information indicating that the distance information is within the range of the distance R1. , The notification form of alerting is selected. Then, the selection unit 23 determines that the notification level is the notification level 1 when the distance information detected by the distance information detection unit 26 is distance information indicating that the distance information is greater than or equal to the distance R1 and is within the range of the distance R2. One notification form is selected.

  In addition, the selection unit 23 determines that the notification level is the notification level 2 when the distance information detected by the distance information detection unit 26 is distance information indicating that the distance information is greater than or equal to the distance R2 and is within the range of the distance R3. 2 The notification form is selected. When the distance information detected by the distance information detection unit 26 is distance information indicating that the distance information is out of the range of the distance R3, the selection unit 23 selects the third notification mode on the assumption that the notification level is the notification level 3. I am doing so.

  In this way, the selection unit 23 reports that the work vehicle 10 is more likely to be stolen as the position information of the work vehicle 10 is farther from the reference point K, so that the notification level is raised from a plurality of notification forms. The notification form by the unit 22 is selected. Therefore, for example, when the worker has just moved the work vehicle 10 for some reason, the distance information detected by the distance information detection unit 26 falls within the range of the distance R1 and is reported from the first notification form. A low-level alerting notification form is selected. Thereby, although it is not theft of the work vehicle 10, it can prevent performing an excessive alerting | reporting with respect to an operator. In addition, since the notification form can be selected according to the possibility of the theft of the work vehicle 10, the worker can determine the possibility of the work vehicle 10 being stolen from the notification form. It is possible to take measures according to the possibility of

  Here, the selection unit 23 uses the notification unit 22 from a plurality of notification forms based on the selection conditions input by the selection condition input units 17 and 33 in addition to the distance information detected by the distance information detection unit 26. A notification form can also be selected. For example, the selection condition input units 17 and 33 can input a selection condition for selecting which notification form from a plurality of notification forms depending on which level the notification level is. Therefore, also in 2nd Embodiment, what kind of alerting | reporting form reports the theft of the working vehicle 10 can be selected by the operator.

  In addition to the distance information detected by the distance information detection unit 26, the selection unit 23 can also select a notification mode by the notification unit 22 from a plurality of notification modes according to the comparison result of the comparison unit 25. For example, if the degree of difference, which is the comparison result of the comparison unit 25, is greater than or equal to a set value, the notification mode by the notification unit 22 can be selected from a plurality of notification modes so as to increase the notification level by one.

  Incidentally, the selection unit 23 selects the alerting notification form when the distance information detected by the distance information detection unit 26 is distance information indicating that the distance information is within the range of the distance R1. The notification form in which the notification of the theft of the work vehicle 10 by the notification unit 22 is not performed can also be selected. Thereby, even when the determination unit 21 determines the first state or the second state, the notification unit 22 does not report the theft of the work vehicle 10 depending on the distance information detected by the distance information detection unit 26. It can also be done.

[Third Embodiment]
In this third embodiment, since the selection contents of the notification form by the selection unit 23 are different from those of the first embodiment and the second embodiment, the difference will be mainly described, and description of other configurations will be omitted. .

  As shown in FIG. 2, the management device 20 includes a notification level setting unit 27 that can set one notification level from a plurality of notification levels. As shown in FIG. 7, for example, the notification level setting unit 27 sets one notification level from a plurality of notification levels based on the comparison result of the comparison unit 25 and the distance information detected by the distance information detection unit 26. It is set. As described above, the comparison unit 25 obtains the difference degrees G1 to G3 as the comparison results, and obtains such a difference degree that G1 <G2 <G3. Further, as described above, the distance information detection unit 26 is configured such that the distance information from the reference point K to the position information of the work vehicle 10 is within the range of the distance R1, or more than the distance R1, as shown in FIG. It is detected whether the distance is within the range of the distance R2, the distance R2 or more and the distance R3, or the distance R3.

  Therefore, as shown in FIG. 7, the notification level setting unit 27 has a difference degree of G1, and the distance information from the reference point K to the position information of the work vehicle 10 is not less than the distance R1 and the range of the distance R2. If it is within, the notification level is set to notification level 1.

  When the difference level is G1, the notification level setting unit 27 indicates that the distance information from the reference point K to the position information of the work vehicle 10 is greater than or equal to the distance R2 and within the range of the distance R3. If it is out of the range of R3, the notification level is set to notification level 2. Further, when the distance information from the reference point K to the position information of the work vehicle 10 is the distance R1 or more and within the range of the distance R2, the notification level setting unit 27 has a difference degree of G2 or G3. The notification level is set to notification level 2.

  The notification level setting unit 27 sets the notification level when the degree of difference is G3 and the distance information from the reference point K to the position information of the work vehicle 10 is greater than or equal to the distance R2 and within the range of the distance R3. The notification level is set to the notification level 3 except when the notification level 1 or the notification level 2 is set.

  And the selection part 23 is comprised so that the alerting | reporting form by the alerting | reporting part 22 may be selected from the some alerting | reporting form according to the alerting | reporting level set in the alerting | reporting level setting part 27. FIG. For example, when the above-described first to third notification modes are set as a plurality of notification modes, when the notification level 1 is set in the notification level setting unit 27, the selection unit 23 performs the first notification. When the notification level setting unit 27 selects the form and the notification level 2 is set, the selection unit 23 selects the second notification form, and the notification level setting unit 27 sets the notification level 3. The selection unit 23 can select the third notification form.

[Another embodiment]
(1) In the first embodiment, when the notification unit 22 notifies the theft of the work vehicle 10, the selection unit 23 uses the distance information detected by the distance information detection unit 26 as shown in FIG. 2. Accordingly, the notification form by the notification unit 22 can be selected from a plurality of notification forms. Accordingly, as in the second embodiment, for example, when the worker has just moved the work vehicle 10 for some reason, the distance information detected by the distance information detection unit 26 is within the range of the distance R1. Thus, a notification mode with a low notification level can be selected. Thereby, although it is not theft of the work vehicle 10, it can prevent performing an excessive alerting | reporting with respect to an operator. In addition, since the notification form can be selected according to the possibility of the theft of the work vehicle 10, the worker can determine the possibility of the work vehicle 10 being stolen from the notification form. It is possible to take measures according to the possibility of

(2) In the first embodiment, the distance information detection unit 26 and the notification level setting unit 27 can be omitted, and in the second embodiment, the comparison unit 25 and the notification level setting unit 27 can be omitted. .
