Description

The present invention relates to a yield management system that manages harvest information of a harvester.

The harvested products harvested by the harvester in the field are transferred from the harvester to a transport vehicle, and are transported by the transport vehicle to a factory or the like that performs various treatments. Even when the harvesting work is performed in a plurality of fields, the harvested products harvested by the harvester in each of the plurality of fields are transferred to a transport vehicle and collected in a factory or the like by the transport vehicle.

Here, in the harvester, for example, the harvest amount information of the harvested product is grasped by the harvest amount detection unit or the like, but when the harvested material is transferred from the harvester to the transport vehicle, the harvested amount information cannot be grasped. .. In factories, etc., by managing the harvest amount information, if the harvest amount of the harvested material transported by the transport vehicle can be grasped, the processing efficiency can be improved. Therefore, even if the harvested material is transferred to the transport vehicle, the harvest is harvested. It is desired to manage the quantity information. Therefore, conventionally, a harvest amount management system has been proposed in which the load capacity of the harvested material transported by the transport vehicle is managed as the harvest amount information (see, for example, Patent Document 1).

In the system described in Patent Document 1, the position information of the harvester, the harvest amount information of the harvested product harvested by the harvester, and the position information of the transport vehicle are acquired. Then, when it is detected from the position information of the harvester and the position information of the transport vehicle that the harvester and the transport vehicle are close to each other, the harvester assumes that the harvested product has been transferred from the harvester to the transport vehicle. The harvest amount information of the harvested harvest is associated with the load amount transported by the transferred transport vehicle, and the load amount of the harvested material transported by the transport vehicle is managed as the harvest amount information.

JP-A-2015-97478

In the system described in Patent Document 1, it is assumed that both the harvester and the transport vehicle are stopped and the harvested material is loaded from the harvester to the transport vehicle and transferred. Therefore, the harvester and the transport vehicle are used for this purpose. The positional relationship with the harvester is the distance from the harvester to the transport vehicle that allows the harvested product to be loaded.

However, assuming that the harvested material has been transferred from the harvester to the transport vehicle by detecting the proximity state, the harvesting work can be performed simply by associating the harvest amount information with the load capacity carried by the transport vehicle. There is a possibility that the yield information and the associated load capacity will be different from the yield information of the crops harvested in, and the yield information cannot be managed appropriately.

For example, depending on the harvester, the harvester and the transport vehicle may run side by side to perform the harvesting work while transferring the harvested product harvested by the harvester to the transport vehicle. In this case, since the harvesting work is performed only when the harvester and the transport vehicle run side by side, the harvesting work is not performed only when the harvester and the transport vehicle are close to each other. In the system described in Patent Document 1, for example, even when the harvester and the transport vehicle are in close proximity to each other and the harvesting operation is not performed, the harvester and the transport vehicle are in close proximity to each other for harvesting. The amount information is associated with the load capacity of the transport vehicle, resulting in an erroneous association.

In view of this situation, the main subject of the present invention is to harvest the harvested product transported by the transporting vehicle when the harvested product harvested by the harvesting machine is transferred to the transporting vehicle and transported. The point is to provide a harvest amount management system that can be appropriately managed as harvest amount information of the harvested product harvested by the harvester.

The first characteristic configuration of the present invention is such that the harvester for harvesting the crop and the transport vehicle are running side by side, and the harvested product harvested by the harvester is transferred to the transport vehicle and freely configured.
The harvester position information acquisition unit that can acquire the position information of the harvester, and
A harvest amount detection unit that can detect the yield amount of the harvested product harvested by the harvester, and
A vehicle position information acquisition unit capable of acquiring the position information of the transport vehicle, and
Based on the harvester position information acquired by the harvester position information acquisition unit and the vehicle position information acquired by the vehicle position information acquisition unit, the harvester and the transport vehicle are in a parallel running state. When it is determined, during the period of maintaining the parallel running state, the harvest amount information sequentially detected by the harvest amount detection unit is repeatedly acquired, the harvest amount information for each acquisition is added, and the harvester is in the parallel running state. The point is that an association unit for performing an association process for associating the harvested product transported by the transport vehicle is provided.

According to this configuration, when the harvester and the transport vehicle run side by side and the harvesting work is performed while transferring the harvested product harvested by the harvester to the transport vehicle, the association unit performs the association process, so that the harvester The harvest amount information detected by the harvest amount detection unit can be associated with the load amount of the harvested material transported by the transport vehicle when the harvesting operation is performed with the transport vehicle running side by side. As a result, the harvest amount information of the harvested product harvested by the harvester by performing the harvesting work can be appropriately associated with the load capacity of the transport vehicle, and the harvested amount of the harvested product harvested by the harvester can be appropriately associated. Information can be managed appropriately.
According to this configuration, since the associating unit performs the association in a state where the harvest amount information is added each time the harvest amount information is acquired, it is possible to grasp the load capacity of the transport vehicle during the harvesting work. As a result, for example, the timing at which the transport vehicle becomes full can be estimated, and measures such as moving another transport vehicle in advance can be taken, and the harvesting work can be performed without interrupting the harvesting work as much as possible. It is possible to improve the efficiency of.

The second characteristic configuration of the present invention includes a harvest state detection unit capable of detecting the harvest state in which the crop is being harvested by the harvester, and the association unit is described in addition to determining that the crop is in a parallel running state. The point is that the association processing is performed when the harvest state is detected by the harvest state detection unit.

According to this configuration, in addition to the determination of the parallel running state, the association unit performs the association process when the harvest state is detected by the harvest state detection unit, so that the crop is actually harvested by the harvester. After confirming that the harvest is being harvested, the yield information can be associated with the load capacity of the transport vehicle. For example, there are cases where crops are not harvested by the harvester even in the parallel running state, and the association can be made excluding such cases, and the load capacity of the harvested material transported by the transport vehicle. Can be managed more accurately as yield information.

The third characteristic configuration of the present invention is a time zone in which the transport vehicle is in a full state based on the load capacity of the harvested product transported by the transport vehicle associated with the association unit and the full amount of the driving vehicle. Is estimated, and based on the estimated time zone and the vehicle position information of the full carrier, another carrier is moved to the position corresponding to the full carrier. The point is that it is equipped with an operation management department that issues commands to transport vehicles .

The fourth characteristic configuration of the present invention is based on the load capacity of the harvested product carried by the transport vehicle associated with the association unit and the vehicle position information acquired by the vehicle position information acquisition unit. The point is that an operation management unit that manages the operation of the transport vehicle is provided so that the amount of the harvested product transported to the transport destination for transporting the harvested product by the transport vehicle is leveled.

By transporting the harvested product to a destination such as a factory by a transport vehicle, the harvested product transported by the transport vehicle is collected at the transport destination such as a factory, and various treatments are performed on the harvested product. Can be done. However, if the amount of harvested material transported to the destination is concentrated in a certain time zone, the amount of harvested material received at the destination becomes too large, and the harvested material cannot be received efficiently. Problems such as a decrease in processing efficiency occur.

Therefore, according to this configuration, the operation management unit determines the harvested material for the transportation destination based on the load capacity of the harvested material transported by the transportation vehicle and the vehicle position information acquired by the vehicle position information acquisition unit. The operation of transportation vehicles is managed so that the amount of transportation is leveled. For example, if the number of transport vehicles arriving at a destination in a certain time zone exceeds the set number, the operation management department will prevent the transport vehicles arriving at the destination from being concentrated in that time zone. The operation can be managed so as to delay the arrival at the destination or accelerate the arrival at the destination for the transport vehicle. In addition, even if the amount of harvested goods transported in a certain time zone exceeds the set amount, the operation management department will prevent the transport vehicles arriving at the destination from being concentrated in that time zone. The operation can be managed so as to delay the arrival at the destination or accelerate the arrival at the destination. In this way, by leveling the amount of the harvested product transported to the destination, it is possible to prevent the above-mentioned problems from occurring.

When sugarcane is harvested by the harvester 1, the harvester 1 and the transport vehicle 50 run side by side as shown in FIG. 2, and the discharge conveyor 25 of the harvester 1 is shown by the middle dotted line in FIG. The discharge direction is changed by operating a hydraulic motor or the like so that the discharge portion of the above is directed toward the loading platform 50A of the transport vehicle 50. As a result, the harvester 1 and the transport vehicle 50 run side by side, and the sugar cane harvesting work is performed while the sugar cane harvested by the harvester 1 is transferred to the transport vehicle 50 by the discharge conveyor 25. The harvester 1 is configured to be able to transfer the harvested harvested material to the transport vehicle 50 in the parallel running state by adjusting the discharge direction of the discharge conveyor 25.

Next, in managing the harvest amount information of the harvester 1, the configuration provided in the harvester 1, the management device 40, and the transport vehicle 50 will be described with reference to FIG.

As described above, the harvester 1 is provided with the harvest amount detection unit 28, and the position information of the harvest state detection unit 31 and the harvester 1 that detect the harvest state in which the crop is being harvested by the harvester 1. The position information acquisition unit 32 and the harvester side communication unit 33 for acquiring the above are provided.

The harvest state detection unit 31 is configured to detect the harvest state, for example, when the harvest clutch is in the ON state. The harvest clutch is a driving force from the engine 29 (drive source) for the harvesting unit (for example, traveling device 2, crop divider 4, base cutter 11, front transfer device 12, rear transfer device 14, etc.) in the harvester 1. It is composed of a clutch that can switch the transmission between the ON state and the OFF state. By turning on this harvest clutch, the harvesting section is activated and the crop can be harvested at the harvesting section.

Further, the harvest state detection unit 31 can be configured to detect the harvest state by detecting, for example, that the harvest amount of the harvested product detected by the harvest amount detection unit 28 is increasing. As described above, the harvest state detection unit 31 may be any one that can detect the harvest state in which the crop is being harvested by the harvest unit, and various harvest state detection units can be applied.

The position information acquisition unit 32 is configured to acquire the position information of the harvester 1 based on the signal from the positioning satellite received by the positioning antenna (not shown) provided in the harvester 1. Here, as a method for acquiring the position information of the harvester 1, for example, independent positioning for acquiring the position information from a signal from a positioning satellite can be applied. Not limited to this single positioning, DGPS (Differential GPS Positioning) that acquires the position information of the harvester 1 by adding the information at the reference station located at the predetermined reference point in addition to the signal from the positioning satellite. , RTK positioning (real-time kinematic positioning) and the like can also be applied, and the position information of the harvester 1 can be acquired by various positioning methods.

Similar to the harvester 1, the transport vehicle 50 is also provided with a position information acquisition unit 51 for acquiring the position information of the transport vehicle 50 and a vehicle-side communication unit 52. The position information acquisition unit 51, like the position information acquisition unit 32 of the harvester 1, is based on a signal from a positioning satellite received by a positioning antenna (not shown) provided in the transport vehicle 50. It is configured to acquire the location information of.

The management device 40 is composed of, for example, a management server or the like having a database, and includes an association unit 41, a storage unit 42, a management side communication unit 44, and the like. The association unit 41 not only manages the harvest amount information of the harvested product harvested by the harvester 1 in association with the harvester 1, but also even when the harvested product is transferred from the harvester 1 to the transport vehicle 50. , The harvest amount information is managed in association with the load amount of the harvested material transported by the transferable transport vehicle 50. The storage unit 42 is configured to be able to store various types of information such as information associated with the association unit 41.

The harvester 1 and the management device 40 are configured to be able to communicate various information via an internet line or the like by the harvester side communication unit 33, the management side communication unit 44, and the like. The transport vehicle 50 and the management device 40 are configured to be able to communicate various information via an internet line or the like by the vehicle-side communication unit 52, the management-side communication unit 44, and the like.

By performing these communications, the management device 40 has the harvester position information acquired by the position information acquisition unit 32, the harvest amount information detected by the harvest amount detection unit 28, and the harvest state detection unit of the harvester 1. It is configured to acquire from the harvesting machine 1 that the harvesting state is detected by 31. Further, the management device 40 is configured to acquire the transportation vehicle position information acquired by the position information acquisition unit 51 from the transportation vehicle 50.

Since the management device 40 acquires the harvester position information and the harvest amount information in real time, the association unit 41 acquires the harvest amount information so that the harvest amount of the harvester 1 can be grasped. Is managed in association with the harvester 1, and the managed information is stored in the storage unit 42. When a plurality of harvesting machines 1 exist, the association unit 41 of the management device 40 manages the harvesting amount information in association with each of the plurality of harvesting machines 1, and the plurality of harvesting machines 1 manage the harvesting amount information. Even if it exists, it is possible to grasp how much the yield is for each of the plurality of harvesters 1.

Here, when performing a harvesting operation for harvesting crops in the field, the harvester 1 and the transport vehicle 50 run side by side as shown in FIG. 2, and the harvester 1 is used as shown by the middle dotted line in FIG. The sugarcane harvesting work is being carried out while the sugarcane harvested in the process is transferred to the transport vehicle 50 by the discharge conveyor 25. Therefore, even if the harvest amount information is managed in association with the harvester 1, if the harvested product of the harvester 1 is transferred to the transport vehicle 50, the harvest amount information cannot be managed.

Therefore, when the harvested product is transferred from the harvester 1 to the transport vehicle 50, the association unit 41 uses the transport vehicle 50 to transfer the harvest amount information of the harvested product harvested by the harvester 1. It is configured to perform an association process that associates it with the load capacity of the harvest to be carried.

In this association process, the association unit 41 receives the harvester position information acquired by the position information acquisition unit 32 of the harvester 1 (corresponding to the harvester position information acquisition unit) and the position information acquisition unit 51 of the transport vehicle 50 (corresponding to the harvester position information acquisition unit). When it is determined that the harvester 1 and the transport vehicle 50 are in a parallel running state based on the vehicle position information acquired by the vehicle position information acquisition unit), the harvest amount detection unit 28 determines in the parallel running state. The detected harvest amount information is associated with the load amount of the harvested material transported by the transport vehicle 50 in the parallel running state.

The association unit 41 informs the harvester position information acquired by the position information acquisition unit 32 of the harvester 1, the vehicle position information acquired by the position information acquisition unit 51 of the transport vehicle 50, and the harvest amount detection unit 28. The harvest amount information detected by the above is repeatedly acquired in real time.

Therefore, for example, the association unit 41 obtains the movement locus of the harvester 1 from the harvest position information repeatedly acquired in real time, and obtains the movement locus of the transport vehicle 50 from the vehicle position information repeatedly acquired in real time. By comparing the obtained movement locus of the harvester 1 with the movement locus of the transport vehicle 50, it is determined whether or not the harvester 1 and the transport vehicle 50 are in a parallel running state.

Regarding the determination of whether or not the harvester 1 and the transport vehicle 50 are running side by side, for example, both the harvest position information and the vehicle position information change with the passage of time, and the harvest position information and the vehicle position information If the distance between the vehicle and the vehicle is constant or substantially constant for a set time, it can be determined that the vehicle is running side by side. Further, it is possible to appropriately change the determination condition of how to determine whether or not the vehicle is in a parallel running state based on the harvest position information and the vehicle position information.

The association unit 41 repeatedly acquires the harvest amount information detected by the harvest amount detection unit 28 in real time while determining that the parallel running state is in the association process, and adds the harvest amount information for each acquisition. It is associated with the load capacity of the harvested material transported by the transport vehicle 50 which is in a parallel running state. While the harvester 1 and the transport vehicle 50 are running side by side, the transfer of the harvested product harvested by the harvester 1 to the transport vehicle 50 is continued, so that every time the harvest amount information is acquired, the transfer is continued. In the state where the harvest amount information is added, the harvest amount information is associated with the load capacity of the harvested material transported by the transport vehicle 50, and the load capacity of the harvested product in the transport vehicle 50 including the increase amount is included in the harvest amount information. It is managed in real time as.

At this time, when the association unit 41 is no longer determined to be in the parallel running state, it is assumed that the parallel running state is released and the harvesting work is completed, and the association of the harvest amount information by the association processing is stopped. Further, even if the association unit 41 is in the parallel running state, when the harvest state is not detected by the harvest state detection unit 31, the association unit 41 can stop the association of the harvest amount information by the association process, assuming that the harvesting work is completed. ..

When a new harvest is transferred to the transport vehicle 50 to which some harvest has already been transferred by performing the harvesting work, the already transferred yield information is associated as the load capacity. Therefore, the association unit 41 associates the newly transferred harvest information as the load capacity of the harvest product to be transported by the transport vehicle 50 in a state of being added to the already associated load capacity.

Here, the association unit 41 not only associates the harvest amount information as the load capacity of the harvested product in the transport vehicle 50 by performing the association process, but also determines in which field the associated harvest amount information is harvested. The harvest position information indicating the above can be associated with the transport vehicle 50. The association unit 41 uses the map information including a plurality of fields and the harvester position information acquired by the harvester 1 position information acquisition unit 32 to perform the harvesting work in which field the harvester 1 performs the harvesting work. We have acquired harvest position information that indicates whether or not we are doing this. Therefore, the association unit 41 identifies the transport vehicle 50 (for example, the transport vehicle 50) in which the harvest is transferred from the harvester 1 when the yield information is associated with the load capacity of the harvest in the transport vehicle 50 in the association process. The harvest position information is associated with the ID information). As a result, it is possible to know in which field the harvested product carried by the transporting vehicle 50 is harvested.

Based on FIG. 4, the conditions for executing the association process in the association unit 41 will be described.
The association unit 41 acquires the harvester position information acquired by the position information acquisition unit 32 of the harvester 1 and the vehicle position information acquired by the position information acquisition unit 51 of the transport vehicle 50 in real time. Based on the harvester position information and the vehicle position information, it is determined whether or not the harvester 1 and the transport vehicle 50 are in a parallel running state (step # 1).

When the association unit 41 determines that the vehicle is in the parallel running state, the association unit 41 determines whether or not the harvest state is detected by the harvest state detection unit 31 (step # 2). When the harvest state detection unit 31 detects the harvest state, the association unit 41 performs the above-mentioned association process (step # 3). In this way, the association unit 41 performs the association process when the harvest state detection unit 31 detects the harvest state, in addition to the determination that the parallel running state is present.

The transport vehicle 50 to which the harvested product harvested by the harvester 1 has been transferred transports the harvested product to a transport destination such as a factory where various treatments are performed on the harvested product. Then, for example, when the harvesting work is performed in a plurality of fields, the harvested product harvested by the harvester 1 in each of the plurality of fields is transferred to the transport vehicle 50, and is transported by the transport vehicle 50 to a factory or the like. It has been collected first.

When the harvesting work is performed in a plurality of fields, the harvested material is transported by each of the plurality of transport vehicles 50, and even in this case, the association unit 41 is the harvester 1 and the transport vehicle 50. The association process is performed every time the parallel running state is reached. As a result, as shown in FIG. 5, in the management device 40, the load capacity of the harvested material (harvest amount Q1 to Q4 in the figure) carried by each of the plurality of transport vehicles 50, and the plurality of transport vehicles 50. The vehicle position information (vehicle positions P1 to P4 in the figure) in each of the above is managed.

In FIG. 5, for example, harvesting work is being performed in each of the fields H1 to H3, and the harvesters 1a to 1c and the transport vehicles 50a to 50c are running side by side. As a result, the association unit 41 performs the association processing with the harvesters 1a to 1c and the transport vehicles 50a to 50c. The harvest amount information of the harvester 1a is associated with the load amount (harvest amount Q1) of the harvested material transported by the transport vehicle 50a, and the harvest amount information of the harvester 1b is the load of the harvested material transported by the transport vehicle 50b. It is associated as the amount (harvest amount Q2), and the harvest amount information of the harvester 1c is associated as the load amount (harvest amount Q3) of the harvested material transported by the transport vehicle 50c. The transport vehicle 50d shows a state in which the harvesting work is completed and the vehicle is heading for a transport destination such as a factory. Therefore, the load capacity (harvest amount Q4) of the harvested material transported by the transport vehicle 50d is also associated with the transport vehicle 50d.

The transport vehicle 50e shows a state on the way to the field where the harvesting work is performed. Since the load capacity of the transport vehicle 50 is zero before the harvesting work is performed, the load capacity of the harvested material transported by the transport vehicle 50e is zero, and the harvested material transported in the figure is zero. The load capacity (harvest amount) is omitted, and the vehicle position information of the transport vehicle 50e is also omitted. By the way, when the harvested product is transported to a transportation destination such as a factory by the transportation vehicle 50, the load capacity of the transportation vehicle 50 is reset to zero.

In this way, in the management device 40, for each of the plurality of transport vehicles 50a to 50e, the vehicle position information (vehicle positions P1 to P4) and the load capacity of the transported harvested material (harvest amount Q1 to Q4). As shown in FIG. 3, the management device 40 is provided with an operation management unit 43 that manages the operation of the transport vehicle 50 based on the management information.

As shown in FIG. 5, the operation management unit 43 has the load capacity (for example, the harvest amount Q1 to Q4 in FIG. 5) and the position information of the harvested material transported by the transport vehicle 50 associated with the association unit 41. Based on the vehicle position information (for example, vehicle positions P1 to P4 in FIG. 5) acquired by the acquisition unit 51, the transport vehicle 50 is used so that the amount of the harvested product transported to the destination such as a factory is leveled. It manages the operation of.

The operation management unit 43 has a moving distance from the vehicle position information (for example, vehicle position P4 in FIG. 5) of the transport vehicle 50 heading to the transport destination such as a factory after the harvesting work to the transport destination. Can be obtained to estimate the arrival time zone at the destination. Further, the operation management unit 43 manages the load capacity (for example, the harvest amount Q4 in FIG. 5) of the harvested material transported by the transport vehicle 50 associated with the association unit 41. Therefore, the operation management unit 43 can determine the number of the transport vehicles 50 arriving at the transport destination and the transport amount of the harvested products to be transported to the transport destination per unit time, and the transport vehicle 50 per unit time. The operation of the transport vehicle 50 is managed so that the transport amount of the harvested product to the transport destination is leveled based on the number of units and the transport amount.

For example, when the number of transport vehicles 50 per unit time in a certain time zone exceeds the set number, the operation management unit 43 is selected so that the transport vehicles 50 arriving at the transport destination are not concentrated in that time zone. By instructing the specific transport vehicle 50 to delay the arrival at the destination or to accelerate the arrival at the destination, it is possible to equalize the amount of the harvested product transported to the destination. Further, for example, when the amount of transportation per unit time in a certain time zone exceeds the set amount, the operation management unit 43 is selected so that the transportation vehicles 50 arriving at the transportation destination are not concentrated in that time zone. By instructing a specific transport vehicle 50 to delay the arrival at the destination or to accelerate the arrival at the destination, it is possible to equalize the amount of the harvested product transported to the destination. Here, regarding the selection of the specific transport vehicle 50, for example, the transport vehicle 50 having a moving distance to the transport destination of a set distance or more can be selected as the specific transport vehicle 50, but based on what conditions. Whether to select it can be changed as appropriate.

Further, the operation management unit 43 grasps, for example, the full amount of the transport vehicle 50, and the full amount and the load capacity of the harvested material in the transport vehicle 50 during the harvesting work (for example, in FIG. 5, the harvest amount Q1 to 1). From the difference from Q3), it is possible to estimate the time zone when the transport vehicle 50 is in the full state. As a result, the operation management unit 43 can see not only the transport vehicle 50 for which the harvesting work has been completed, but also the transport vehicle 50 during the harvesting work in the estimated full time zone and the transport vehicle that is in the full state. Based on the vehicle position information of 50, the arrival time zone to the transportation destination can be estimated. Therefore, the operation management unit 43 includes not only the transport vehicle 50 for which the harvesting work has been completed, but also the transport vehicle 50 during the harvesting work so that the transport amount of the harvested product to the transport destination is leveled. You can manage the operation.

Here, when delaying the arrival of the specific transport vehicle 50 at the transport destination, for example, the harvester 1 is moved to another field where the harvester 1 is present, and harvesting work is performed in the other field to reach the transport destination. You can also delay the arrival of.

As described above, the operation management unit 43 can estimate the time zone when the transport vehicle 50 is in the full state, and is based on the estimated time zone and the vehicle position information of the transport vehicle 50 which is in the full state. Therefore, it is possible to instruct the other transport vehicle 50 to move the other transport vehicle 50 to the field where the full transport vehicle 50 is located according to the estimated time zone. As a result, even if the transport vehicle 50 becomes full during the harvesting work in the field, another transport vehicle 50 can be moved to the field in advance, so that another transport vehicle can be immediately moved. The harvesting work can be continued in a state where the harvested material is transferred to 50, the interruption time of the harvesting work can be shortened, and the efficiency of the harvesting work can be improved.

Further, as described above, the association unit 41 not only associates the harvest amount information with the load capacity of the harvested product in the transport vehicle 50, but also associates the harvest position information with the transport vehicle 50 by performing the association process. Therefore, the management device 40 can manage the harvest position information indicating in which field the harvested product being transported is harvested for each of the plurality of transport vehicles 50. For example, the state of the harvest, such as the quality of the harvest, may vary from field to field. In such a case, the management device 40 manages the harvest position information for each of the plurality of transport vehicles 50, so that the harvested product to be processed is harvested in which field at the transport destination such as a factory. After grasping whether or not there is, various treatments can be performed on the harvested product to be processed, which can improve the processing efficiency and respond to the condition of the harvested product such as the quality of the harvested product. Appropriate processing can be performed.

[Another Embodiment]
(1) In the above embodiment, while the association unit 41 determines in the association process that it is in a parallel running state, the harvest amount information detected by the harvest amount detection unit 28 is repeatedly acquired, and each acquisition thereof. It is associated with the load capacity of the harvested material transported by the transport vehicle 50 which is in a parallel running state in the state where the harvest amount information of the above is added. It can be changed as appropriate whether it is related to the load capacity of the harvested product.

For example, the time when the parallel running state is reached is the start time of the harvesting work, the time when the parallel running state is released is the end time of the harvesting work, and at the end of the harvesting work, from the start time of the harvesting work to the end time of the harvesting work. The total value of the harvest amount information can be associated with the load amount of the harvested material transported by the transport vehicle 50.

Further, after the parallel running state is reached and before the parallel running state is released, for example, when the harvest clutch is turned off and the harvesting state detection unit 31 does not detect the harvesting state, the parallel running state is set. The time when the harvesting work is started is set as the start time of the harvesting work, the time when the harvesting state is no longer detected by the harvesting state detection unit 31 is set as the end time of the harvesting work, and at the end of the harvesting work, the harvesting work is finished from the start time of the harvesting work. The total value of the harvest amount information up to the time point can be associated with the load amount of the harvested material transported by the transport vehicle 50.

(2) In the above embodiment, in addition to the determination that the association unit 41 is in the parallel running state, the association process is performed when the harvest state detection unit 31 detects the harvest state. If it is determined that the unit 41 is in the parallel running state regardless of whether or not the harvest state detection unit 31 has detected the harvest state, the unit 41 can also perform the association processing.
