The present invention relates to a work management system that manages harvesting work performed by a first harvester and a second harvester in one field.

Conventionally, in order to finish the field work quickly, the field work has been performed while traveling in one field with a plurality of work vehicles. As such a technique, for example, there is one described in Patent Document 1.

Patent Document 1 discloses a vehicle control system in which a target traveling position is sequentially determined based on a position in which the parent work vehicle actually travels, and the child work vehicle travels toward the target traveling position. In this vehicle control system, the child work vehicle is configured to follow and travel so as to maintain a predetermined offset amount set with respect to the parent work vehicle.

U.S. Patent Publication No. 6732024

In the technique described in Patent Document 1, the child work vehicle maintains a preset amount of offset in each of the longitude direction and the latitude direction with respect to the parent work vehicle, and the travel locus of the parent work vehicle is set as a work width. The vehicle travels along the target travel route that has been translated by the amount. However, the parent work vehicle and the child work vehicle cannot always work in the same field, and in such a case, the child work vehicle cannot travel. Further, in the harvesting machine that performs the harvesting work, a predetermined work vehicle performs the harvesting work of the outer peripheral portion in the field for one field, and the harvesting work of the central region inside the outer peripheral portion is another work. It is also expected that the car will do it. In such a case, it is not easy to share the harvesting work with the technique described in Patent Document 1.

Therefore, there is a need for a work management system that manages the harvesting work performed by the first harvester and the second harvester in one field.

A traveling route generation unit that generates a traveling route on which the second harvester travels while performing harvesting work on the inner central region of the outer peripheral portion based on the map information, and the second The point is that the harvester is provided with a travel control unit that automatically travels the second harvester while performing the harvesting operation based on the travel path.

With such a characteristic configuration, the second harvester can automatically run the harvesting work in the central region of the field where the harvesting work of the outer peripheral portion is completed by the first harvester. Therefore, it is possible to smoothly carry out the harvesting work of one field. In addition, according to this configuration, a skilled person is in charge of the harvesting work of the outer peripheral part that requires skill, and a non-skilled person is boarded as an assistant on the second harvesting machine that automatically performs the harvesting work. It can be done appropriately, and it is possible to improve work efficiency. Further, according to this configuration, for example, in the evening, when it becomes dim, the first harvester completes the harvesting work only on the outer peripheral portion, and after it becomes dark, the second harvester automatically performs the harvesting work in the central region. It is also possible.

Further, it is preferable that the map information acquisition unit automatically acquires the map information of the field including the central region when the second harvester is assigned the harvesting work of the central region.

With such a configuration, it is possible to reduce the time and effort for the second harvester to acquire the map information of the field to which the harvesting work is assigned. Further, for example, it is possible to suppress an increase in the amount of data communication by not acquiring map information of a field to which harvesting work is not assigned.

Further, it is preferable that the second harvester is provided with a notification unit that notifies when the map information acquisition unit acquires the map information.

With such a configuration, it is possible to notify the worker who uses the second harvester that the map information has been acquired. Therefore, the second harvester can smoothly proceed with the harvesting work of the field based on the map information.

Further, it is preferable that there are a plurality of the second harvesters and the map information is distributed to all the second harvesters.

With such a configuration, even if one of the plurality of second harvesters interrupts the harvesting work in the field, the other second harvester takes over the harvesting work. Can be done. Therefore, the harvesting work can be smoothly completed.

Further, it is preferable that the map information is generated by the first harvester.

With such a configuration, it is not necessary to transmit the data necessary for generating the map information to the outside, so that an increase in the amount of data required for communication can be suppressed.

In addition, status information acquisition for acquiring status information indicating the progress of the harvesting work from the first harvesting machine having a plurality of the first harvesting machines and performing the harvesting work on the outer peripheral portion of the field. It is preferable that the unit is provided so that the status information can be shared with the first harvester that has not performed the harvesting work on the outer peripheral portion of the plurality of first harvesters.

With such a configuration, even if one of the first harvesters interrupts the harvesting work in the field, the other first harvester takes over the harvesting work. Can be done. Therefore, the harvesting work can be smoothly completed.

The work management system according to the present invention has a function of managing the work shared by a plurality of harvesters in one field. Hereinafter, the work management system 100 of this embodiment will be described. In the present embodiment, an example will be described in which the work management system 100 manages the harvesting work performed by the first harvesting machine 1 and the second harvesting machine 2 in one field. In the following, when it is not necessary to distinguish between the first harvester 1 and the second harvester 2, the harvester 10 will be collectively referred to as the harvester 10.

FIG. 1 is a side view of the harvester 10 of the present embodiment. In the following, the harvester 10 of the present embodiment will be described by taking a so-called ordinary combine as an example. Of course, the harvester 10 may be a head-feeding combine.

Here, in order to facilitate understanding, in the present embodiment, unless otherwise specified, "front" (direction of arrow F shown in FIG. 1) means front in the front-rear direction (traveling direction) of the aircraft, and " "Rear" (direction of arrow B shown in FIG. 1) means rearward in the front-rear direction (traveling direction) of the aircraft. Further, the left-right direction or the lateral direction shall mean the airframe crossing direction (airframe width direction) orthogonal to the airframe front-rear direction. Further, "up" (direction of arrow U shown in FIG. 1) and "down" (direction of arrow D shown in FIG. 1) are positional relationships in the vertical direction (vertical direction) of the aircraft, and are relative to the ground height. It shall indicate the relationship.

As shown in FIG. 1, the harvester 10 includes a traveling vehicle body 11, a crawler-type traveling device 12, a driving unit 13, a threshing device 14, a grain tank 15, a harvesting unit H, a transport device 16, and a grain discharging device 17. A position detection module 18 is provided.

The traveling device 12 is provided in the lower part of the traveling vehicle body 11 (hereinafter referred to as "vehicle body 11"). The harvester 10 is configured to be self-propelled by the traveling device 12. The driving unit 13, the threshing device 14, and the grain tank 15 are provided on the upper side of the traveling device 12, and form the upper part of the vehicle body 11. The operation unit 13 can be boarded by a driver who operates the harvester 10 and a monitor who monitors the work of the harvester 10. Usually, the driver and the observer also serve concurrently. When the driver and the observer are different persons, the observer may monitor the work of the harvester 10 from outside the harvester 10.

The grain discharge device 17 is connected to the lower rear portion of the grain tank 15. Further, the position detection module 18 is attached to the front upper part of the driving unit 13 and detects the position of the own vehicle of the harvester 10. As the position detection module 18, it is possible to use a satellite positioning module configured as a GNSS module. The position detection module 18 has a satellite antenna for receiving GPS signals and GNSS signals (referred to as “GPS signals” in this embodiment) from the artificial satellite GS (see FIG. 2). The position detection module 18 can include an inertial navigation module incorporating a gyro acceleration sensor and a magnetic compass sensor in order to complement satellite navigation. Of course, the inertial navigation module may be provided at a place different from the position detection module 18. The position detection module 18 detects the position of the own vehicle, which is the position of the harvester 10, based on the GPS signal and the detection result of the inertial navigation module described above. The position of the own vehicle detected by the position detection module 18 is used for automatic traveling (autonomous traveling) of the harvester 10 and for each functional unit described later. The position detection module 18 is used in the first harvester 1 (see FIG. 2) and the second harvester 2 (see FIG. 3), respectively. In the following description, when distinguishing between them, the position detection module 18 provided in the first harvester 1 is shown as the position detection module 18A, and the position detection module 18 provided in the second harvester 2 is the position detection module 18B. Shown as.

The harvesting unit H is provided at the front portion of the harvesting machine 10. The transport device 16 is provided on the rear side of the harvesting portion H. The harvesting unit H has a cutting mechanism 19 and a reel 20. The cutting mechanism 19 cuts the planted culm in the field. The reel 20 scrapes the planted culm to be harvested while rotating and driving. With such a configuration, the harvesting unit H can harvest grains (a type of agricultural product) in the field. The harvester 10 can perform work traveling by the traveling device 12 while harvesting grains in the field by the harvesting unit H.

The cut grain culm cut by the cutting mechanism 19 is conveyed to the threshing device 14 by the conveying device 16. In the threshing device 14, the harvested culm is threshed. The grains obtained by the threshing treatment are stored in the grain tank 15. The grains stored in the grain tank 15 are discharged to the outside of the machine by the grain discharging device 17 as needed.

FIG. 2 is a diagram showing an outline of the work of the first harvester 1. As shown in FIG. 2, the first harvester 1 performs harvesting work (peripheral cutting) of the outer peripheral portion in the field. First, the driver / observer manually operates the first harvester 1 and, as shown in FIG. 2, performs a harvesting run so as to orbit along the boundary line of the field in the outer peripheral portion of the field. As a result, the area that has become the mowed land (already worked area) is set as the outer peripheral area SA. The area left as uncut land (unworked land) inside the outer peripheral area SA is set as the work target area CA.

At this time, in order to secure a certain width of the outer peripheral region SA, the driver runs the first harvester 1 for 2 to 3 laps. In this traveling, the width of the outer peripheral region SA is expanded by the working width of the first harvesting machine 1 every time the first harvesting machine 1 makes one round. For example, when the first two to three laps have been completed, the width of the outer peripheral region SA becomes about two to three times the working width of the first harvester 1. The first lap run by the driver is not 2 to 3 laps, but may be more (4 laps or more) or 1 lap.

The outer peripheral region SA is used as a space for changing the direction when the second harvester 2 performs harvesting traveling (peripheral cutting) in the work target region CA. Further, the outer peripheral region SA is also used as a space for movement such as when moving to a grain discharge place or a refueling place after the harvesting run is finished.

FIG. 2 also shows a transport vehicle CV in which the grains harvested by the harvester 10 are discharged and transported. When discharging the grains, the harvester 10 moves to the vicinity of the transport vehicle CV and discharges the grains to the transport vehicle CV via the grain discharge device 17.

When the outer peripheral area SA and the work target area CA are set by the manual operation described above, the travel route in the work target area CA is calculated as shown in FIG. The calculated travel route is sequentially set based on the work travel pattern, and the second harvester 2 is automatically controlled to travel so as to travel along the set travel route. This allows the second harvester 2 to perform harvesting work in the central region of the field.

Next, the work management system 100 that manages the work of the first harvester 1 and the second harvester 2 will be described. FIG. 4 is a block diagram showing the configuration of the work management system 100 of the present embodiment. As shown in FIG. 4, the work management system 100 includes a first position information acquisition unit 21, a map information generation unit 22, a second position information acquisition unit 31, a map information acquisition unit 32, a notification unit 33, and a travel route generation unit. 34, each functional unit of the travel control unit 35 is provided. Each of these functional units is constructed with hardware, software, or both with a CPU as a core member in order to perform processing related to management of field work.

The first position information acquisition unit 21 is provided in the first harvesting machine 1, and during the harvesting work of the outer peripheral portion in the field, the own vehicle position information indicating the own vehicle position of the first harvesting machine 1 is used as the first position information. get. The first harvester 1 is a vehicle that travels by manually operating the worker to harvest the outer peripheral portion of the field as described above. The position detection module 18A described above is provided in the first harvester 1, and the first position information acquisition unit 21 acquires the own vehicle position information detected by the position detection module 18A as the first position information.

The second position information acquisition unit 31 is provided in the second harvester 2 and acquires the first position information as the second position information. The second harvester 2 is a vehicle that automatically travels to harvest the central region of the field as described above. The first position information is information detected by the position detection module 18A as the own vehicle position information of the first harvester 1, and is acquired by the first position information acquisition unit 21. The first position information is the own vehicle position information of the first harvester 1. Therefore, the second position information also corresponds to the own vehicle position information of the first harvester 1. The second position information acquisition unit 31 acquires such first position information as the second position information. Therefore, the first position information is transmitted from the first harvester 1 to the second harvester 2. Such transmission can be performed by communication via, for example, a network.

The map information acquisition unit 32 is provided in the second harvester 2 and acquires map information indicating the shape of the field based on the second position information. The second position information is acquired by the second position information acquisition unit 31. The map information indicating the shape of the field is information indicating the outer shape and position of the field and the shape and position of the central region. The map information acquisition unit 32 acquires such map information.

Here, in the present embodiment, the map information is generated by the map information generation unit 22 of the first harvester 1. Therefore, the map information acquisition unit 32 acquires the map information from the map information generation unit 22.

Although the details will be described later, a work plan such as which field is used and what kind of harvesting work is to be performed may be assigned to each of the first harvesting machine 1 and the second harvesting machine 2 in advance. Whether or not such a work plan is assigned can be grasped by the work management system 100 delivering the work plan to the operation terminals of the first harvester 1 and the second harvester 2. Therefore, when the second harvester 2 is assigned the harvesting work of the central region, the map information acquisition unit 32 may be configured to automatically acquire the map information of the field including the central region.

Further, in the present embodiment, when the map information acquisition unit 32 acquires the map information, the notification unit 33 provided in the second harvester 2 notifies the map information. When the map information acquisition unit 32 acquires the map information, it is preferable to transmit the information indicating that the map information acquisition unit 32 has acquired the map information to the notification unit 33. Upon receiving this information, the notification unit 33 can perform notification. The notification by the notification unit 33 may be voice, or the lamp, LED, or the like may be blinked or turned on. Also, some of voice, blinking and lighting may be used.

Based on the map information, the travel route generation unit 34 generates a travel route on which the second harvester 2 travels while performing harvesting work in the central region inside the outer peripheral portion. As described above, the map information corresponds to the information indicating the outer shape and position of the field and the shape and position of the central region. Therefore, the travel route generation unit 34 uses the information indicating the shape and position of the central region included in the map information to generate a travel route to travel while performing harvesting work in the central region as shown in FIG. Since the second harvester 2 automatically travels along this travel path, the travel path generation unit 34 generates the travel path including the turning path in which the second harvester 2 turns in the outer peripheral portion. The generation of such a traveling route can be performed by using various known methods. Therefore, detailed description thereof will be omitted here.

The travel control unit 35 is provided in the second harvester 2 and automatically travels the second harvester 2 while performing harvesting work based on the travel route. Further, since the travel control unit 35 automatically travels based on the travel route, the vehicle position information indicating the vehicle position of the second harvester 2 detected by the position detection module 18B provided in the second harvester 2. Is used. The travel control unit 35 automatically travels the second harvester 2 so that the vehicle position indicated by the vehicle position information is aligned with the travel route generated by the travel route generation unit 34.
