A communication unit 42 , a plurality of controllers 43 , a position information calculation unit 44 , a storage unit 45 and a notification unit 46 are electrically connected to the work vehicle control unit 40 . The communication unit 42 is a communication interface for wirelessly communicating with the monitoring server 4 .

A plurality of controllers 43 controls each part of the work vehicle 2 . Specifically, the plurality of controllers 43 include an engine controller that controls the number of rotations of the engine, a vehicle speed controller that controls the vehicle speed of the work vehicle 2, a steering controller that controls the direction of the work vehicle 2, and an elevation controller for the work implement 11. and a PTO controller that controls the PTO clutch to switch whether or not to transmit the rotation of the PTO shaft to the working machine 11, and the like.

The position information calculator 44 is electrically connected to a satellite signal reception antenna 47 attached to the traveling body 10 (see FIG. 1). The satellite signal receiving antenna 47 receives signals from positioning satellites that constitute the satellite positioning system. The satellite positioning system is, for example, GNSS (Global Navigation Satellite System). A positioning signal received by the satellite signal reception antenna 47 is input to the position information calculation unit 44 . The position information calculation unit 44 calculates and acquires the position information of the work vehicle 2 (strictly speaking, the satellite signal reception antenna 47) as latitude/longitude information, for example. The position information calculation unit 44 is also called a position information acquisition unit.

The storage unit 45 is composed of a storage device such as a nonvolatile memory. The position information and work information of work vehicle 2 are stored in at least one of storage unit 45 and memory 41 . The work information is information related to farm work performed by the work vehicle 2 . The work information includes information regarding ON/OFF of the PTO clutch that transmits the rotation of the PTO shaft to the work implement 11, and the like. The position information and work information of the work vehicle 2 are transmitted to the monitoring server 4 via the communication unit 42 .

The notification unit 46 includes, for example, at least one of a monitor and a speaker provided on the traveling body 10 of the work vehicle 2 . The notification unit 46 notifies the owner of the work vehicle 2 of various warnings. If the notification unit 46 includes a speaker, an audio notification is given at the time of warning. If the notification unit 46 includes a monitor, a warning image is used for notification when a warning is issued.
The monitoring server 4 includes a server control unit 50 that controls the monitoring server 4 . The server control unit 50 includes a microcomputer having a CPU and memory (ROM, RAM, etc.) 51 . A communication unit 52 , an operation display unit 53 , an operation unit 54 and a storage unit 55 are electrically connected to the server control unit 50 .

The storage unit 55 is composed of a storage device such as a hard disk or nonvolatile memory.
The position information and work information transmitted from the work vehicle 2 are acquired by the server control section 50 via the communication section 52 . Storage unit 55 includes a position information storage unit 60 that stores position information received from work vehicle 2 and a work information storage unit 61 that stores work information received from work vehicle 2 .

The owner of the work vehicle 2 can receive services provided by the business such as creating a work diary and setting a work plan for the work vehicle 2 by contracting with the business. Specifically, the work vehicle 2 transmits its own position information and work information to the monitoring server 4 . The monitoring server 4 analyzes the position information and work information received from the work vehicle 2, and creates a work diary of farm work performed by the work vehicle 2, sets a work plan, and the like. The monitoring server 4 manages so that only the owner of the work vehicle 2 can view the work diary and work plan of the work vehicle 2 .

In such a service, the work vehicle 2 is resold from the owner of the work vehicle 2 who is the contractor (hereinafter referred to as the "old owner") to another person (hereinafter referred to as the "new owner"). Despite this, the owner of the work vehicle 2 registered in the monitoring server 4 may remain the former owner. In such a case, there is a risk that the work information of the farm work performed by the new owner using the work vehicle 2 will be provided to the former owner via the monitoring server.

Therefore, in the work vehicle monitoring system 1, when the work vehicle 2 continues to exist outside the predetermined area A set based on the past position information of the work vehicle 2 for a predetermined time (for example, three months), the work The new owner is notified via the work vehicle 2 that the owner of the work vehicle 2 registered in the monitoring server 4 may remain the former owner despite the vehicle 2 being resold. is configured to

The past position information is, for example, position information of the work vehicle 2 acquired by the position information calculation unit 44 over a predetermined position information acquisition period (for example, six months after contract with the business operator). Referring to FIG. 3, when work vehicle 2 is moving between a plurality of farm fields F owned by the owner of work vehicle 2 and parking position P during the position information acquisition period, past position information includes position information of a plurality of farm fields F and parking positions P. In this case, an area within a predetermined distance L1 (eg, 3 km) from a polygon 80 including position information of a plurality of fields F and parking positions P is set as the predetermined area A.

The server control unit 50 of the monitoring server 4 controls the predetermined area setting unit 71 that sets the predetermined area A based on the past location information stored in the location information storage unit 60, and after the location information acquisition period has passed (the operator a determination unit 70 that determines whether or not the work vehicle 2 continues to exist outside the predetermined area A for a predetermined period based on the position information of the work vehicle 2 after six months from the contract with the company. The predetermined area A set by the predetermined area setting section 71 is stored in the storage section 55 . That is, the storage section 55 includes a predetermined area storage section 62 .

When the determination unit 70 determines that the work vehicle 2 continues to exist outside the predetermined area A for a predetermined period of time, the server control unit 50 of the monitoring server 4 issues an abnormal state occurrence notification that an abnormal state has occurred. It is transmitted toward the work vehicle 2 . A state in which there is a possibility that the owner of the work vehicle 2 registered in the monitoring server 4 remains the former owner even though the work vehicle 2 has been resold is called an abnormal state.

When the work vehicle control unit 40 of the work vehicle 2 receives the abnormal state occurrence notification, the notification unit 46 of the work vehicle 2 notifies the new owner of the work vehicle 2 of the occurrence of the abnormal state. That is, the notification unit 46 functions as an abnormality notification unit. If the owner of the work vehicle 2 registered in the monitoring server 4 remains the former owner even though the work vehicle 2 has been resold, the new owner is the operator of the monitoring server 4 or the former owner. can prompt the person to change the contract status. On the other hand, if the work vehicle 2 continues to exist outside the predetermined area A for a predetermined period of time due to, for example, moving of the owner, and the work vehicle 2 is not resold, the work vehicle 2 can inform the monitoring server 4 that the resale has not been carried out.

According to the first embodiment, when the work vehicle 2 has been out of the predetermined area A for a predetermined period of time, the notification unit 46 notifies the owner of the work vehicle 2 of the occurrence of an abnormal condition. Therefore, for example, when the work vehicle 2 is resold and the management location of the work vehicle 2 is changed to outside the predetermined area A, the new owner is notified of the occurrence of an abnormal condition. Conversely, if the work vehicle 2 is not resold and is managed for a short period of time at a maintenance center (not shown) outside the predetermined area A for maintenance or the like, The occurrence of abnormal conditions is not reported. Therefore, it is possible to reduce the frequency of notification that the owner of work vehicle 2 has been changed even though the owner of work vehicle 2 has not been changed.

According to the first embodiment, the predetermined area A is set based on past position information. That is, since the predetermined area A is set based on the positional information to which the work vehicle 2 has moved in the past, when the work vehicle 2 is not resold, the frequency of the work vehicle 2 being located outside the predetermined area A is reduced in the first place. Therefore, it is possible to reduce the frequency of notification that the owner of work vehicle 2 has been changed even though the owner of work vehicle 2 has not been changed.

Further, in the case where the predetermined area A is set based on the past position information, when the work vehicle 2 is moved to the maintenance center during the position information acquisition period (for example, six months after the contract with the business operator), these is included in the polygon 80. In this case, the maintenance center exists within the predetermined area A. Therefore, even if the work vehicle 2 is left in the maintenance center for a long period of time (for example, a period longer than three months) after the position information acquisition period has passed, the work vehicle 2 cannot be Abnormal state occurrence notification is not sent.

Unlike the first embodiment, as shown in FIG. 4, the predetermined area A is set as an area within a predetermined distance L2 (eg, 3 km) from a predetermined reference position S (eg, parking position P). may be In this case, the storage unit 55 of the monitoring server 4 includes a reference position storage unit 63 that stores the reference position S (see the two-dot chain line in FIG. 2).
According to this configuration, the predetermined area A can be set early. Therefore, it is possible to early reduce the frequency of notification that the owner of work vehicle 2 has been changed even though the owner of work vehicle 2 has not been changed.

The reference position S may be the address of the owner described in the contract prepared when the owner of the work vehicle 2 and the business operator make a contract. In this case, since the monitoring server 4 can set the reference position S based on the description of the contract, the predetermined area A can be set much earlier.
<Second embodiment>
FIG. 5 is a block diagram showing the electrical configuration of a work vehicle monitoring system 1P according to the second embodiment of the invention. The main difference between the work vehicle monitoring system 1P and the work vehicle monitoring system according to the first embodiment (see FIG. 2) is that the work vehicle control unit 40 includes a determination unit 72 instead of the server control unit 50. .

In the work vehicle monitoring system 1P, the position information (predetermined area information) of the predetermined area A set by the predetermined area setting section 71 of the server control section 50 is transmitted to the work vehicle 2 . Also in the second embodiment, as in the first embodiment, the predetermined area A may be an area set based on past position information as shown in FIG. , the area set based on the reference position S. FIG.

When receiving the predetermined area information 75 , the work vehicle control unit 40 stores the predetermined area information 75 in the memory 41 . Based on the predetermined area information 75 and the position information stored in the storage unit 45, the determination unit 72 of the work vehicle control unit 40 determines whether the work vehicle 2 continues outside the predetermined area A for a predetermined period (for example, three months). determines whether it exists in That is, the determination unit 70 of the work vehicle control unit 40 determines whether the work vehicle 2 continues to exist outside the predetermined area A for a predetermined period based on the position information of the work vehicle 2 after the position information acquisition period has passed. determine whether or not The storage unit 45 includes a position information storage unit 76 that stores position information of the work vehicle 2 for a predetermined period (for example, three months) or longer.

The second embodiment also has the same effect as the first embodiment.
<Other embodiments>
The present invention is not limited to the embodiments described above, but can be embodied in other forms.
For example, in the above-described embodiment, the determination units 70 and 72 determine whether or not the work vehicle 2 continues to exist outside the predetermined area A for a predetermined period based on the position information acquired by the position information calculation unit 44. judge. However, the determination units 70 and 72 determine whether or not the work was performed by the work vehicle 2 while the work vehicle 2 was outside the predetermined area A, based on the position information acquired by the position information calculation unit 44. You can judge. In this case, the determination as to whether or not the work has been performed by the work vehicle 2 is made based on the work information. Specifically, the work information includes information as to whether or not the rotation of the PTO shaft has been transmitted to the work implement 11 .

If the work information includes information that the PTO controller has controlled the PTO clutch so that the rotation of the PTO shaft is transmitted to the work implement 11, the determination units 70 and 72 determine that the work by the work vehicle 2 has been performed. judge. Conversely, if the work information includes information that the PTO controller has controlled the PTO clutch so that the rotation of the PTO shaft is not transmitted to the work implement 11, the determination units 70 and 72 determine that the work vehicle 2 is performing work. It is determined that it was not broken.

When the determination units 70 and 72 determine that the work vehicle 2 has performed work while the work vehicle 2 is outside the predetermined area A, the notification unit 46 notifies that an abnormal state has occurred. Therefore, for example, when the work vehicle 2 is resold and the work vehicle 2 starts working in a place (field) outside the predetermined area A, the new owner is notified of the occurrence of an abnormal condition. Conversely, even if the work vehicle 2 is not resold and the work vehicle 2 is managed in a maintenance center outside the predetermined area A for a short period of time for maintenance or the like, the work is not performed. In this case, the occurrence of an abnormal condition is not reported. Therefore, it is possible to reduce the frequency of notification that the owner of work vehicle 2 has been changed even though the owner of work vehicle 2 has not been changed.

In addition, in the above-described embodiment, the notification unit 46 provided in the work vehicle 2 notifies the occurrence of an abnormal state. However, unlike the above-described embodiment, the monitoring server 4 may be provided with a notification unit 85 that notifies the occurrence of an abnormal state (see two-dot chain lines in FIGS. 2 and 5). In this case, the notification section 85 is electrically connected to the server control section 50 .
Reporting unit 85 includes, for example, at least one of a monitor and a speaker provided in monitoring server 4 . The notification unit 85 notifies the operator of the monitoring server 4 of the occurrence of an abnormal state. If the notification unit 85 includes a speaker, an audible notification is provided when an abnormal condition occurs. If the notification unit 85 includes a monitor, a warning image is used to notify when an abnormal condition occurs.

The operator of the monitoring server 4 can inform the new owner of the work vehicle 2 that the contractor may remain the old owner even though the work vehicle 2 has been resold.
Further, the abnormality notification unit may be provided in the wireless communication terminal 3 capable of wirelessly communicating with the work vehicle 2 by WiFi or the like (see two-dot chain line in FIG. 1). The wireless communication terminal 3 may be configured to communicate with the monitoring server 4 via the work vehicle 2 or may be configured to communicate with the monitoring server 4 via the communication network 5 . When the determination unit 72 of the work vehicle control unit 40 (see FIG. 5) or the determination unit 70 of the monitoring server 4 (see FIG. 2) determines that the work vehicle 2 continues to exist outside the predetermined area A for a predetermined period of time , the wireless communication terminal 3 notifies the owner of the work vehicle 2 of the occurrence of an abnormal state by means of an image or sound.
