In the following description, the global positioning satellite system will be referred to as GNSS.

The rice transplanter 1 includes a traveling machine 11, a rice planting work device 12 (an example of a field work device), a GNSS 13 (an example of a positioning device), a rice transplanter side control unit 14, a travel control unit 15, and a touch panel terminal 2 (an example of a touch panel terminal 2). An example of a monitoring device) and.

The rice planting work device 12 is configured in a multi-row planting format (for example, 8-row planting), and the number of planting rows can be changed by operating each row clutch (not shown).

The travel control unit 15 has an automatic travel mode and a manual travel mode, and can set in advance transition conditions for permitting the transition from the manual travel mode to the automatic travel mode. The transition conditions are, for example, that the reference line has been registered, that the steering angle of the steering wheel is within a preset range, and that the path parallel to the reference line is continuously set over a preset distance. It can be said that the vehicle is traveling in a straight line.

The touch panel terminal 2 includes a touch panel 21 (an example of a display unit), a terminal control unit 22, a display control unit 23, and a communication unit 24. The terminal control unit 22 includes a own machine position information acquisition unit 221, a travel locus information acquisition unit 222, a work device information acquisition unit 223, and a work area identification unit 224. The functions of each unit included in the terminal control unit 22 will be described below.

The own machine position information acquisition unit 221 communicates with the rice transplanter side control unit 14 via the communication unit 24, and acquires the own machine position information 31 by the GNSS 13.

The traveling locus information acquisition unit 222 acquires the traveling locus information 32 of the traveling aircraft 11 based on the history of the own machine position information 31. Further, in the automatic traveling mode described later, the traveling locus information acquisition unit 222 identifies the moving direction of the rice transplanter 1 based on the history of the traveling locus information 32, and acquires this as the traveling direction information 321.

The work device information acquisition unit 223 communicates with the rice transplanter side control unit 14 via the communication unit 24, and acquires the work device information 33 which is information about the rice transplanter work device 12. The work device information 33 includes work width information 331 indicating the work width of the rice planting work device 12, and operating state information 332 representing the number of rice planting rows of the rice planting work device 12.

The work area identification unit 224 identifies the work area information 34 based on the travel locus information 32 and the work device information 33. The work area information 34 includes the existing work area 341, the unworked area 342, and the overlapping area 343.

The display control unit 23 displays each of the above information and a plurality of icons 35 to which the function as a touch button for operating the rice transplanter 1 and the touch panel terminal 2 is assigned on the touch panel 21. The icon 35 includes a start point registration icon 35A assigned to the function of registering the start point of the reference line for the automatic driving mode, an end point registration icon 35B assigned to the function of registering the end point of the reference line, and an automatic driving mode.

The information and the icon 35 displayed on the touch panel 21 are appropriately selected depending on the work situation, the manual selection by the operator, and the like.

Subsequently, the display of the work area information 34 by the touch panel terminal 2 of the rice transplanter 1 will be described. When the start of the work is input to the touch panel terminal 2 at the start of the rice planting work, the own machine position information 31 and the work device information 33 are acquired as described above, and these information are displayed on the touch panel 21. When the running in the state where the rice planting work device 12 is operated is started, the running locus information 32 is acquired and the discrimination between the existing work area 341 and the unworked area 342 is started. The display control unit 23 displays the travel locus information 32 on the touch panel, and displays the already-worked area 341 and the unworked area 342 in different colors. For example, the existing work area 341 is displayed in green, and the unworked area 342 is displayed in brown.

The width of the area recognized as the existing work area 341 corresponding to the traveling locus information 32 in a row is determined by the work width information 331 and the operation state information 332. The work width information 331 includes, for example, a work width based on the model information of the rice planting work apparatus 12, and the operating state information 332 includes, for example, the number of rice planting rows of the rice planting work apparatus 12. That is, the working width is increased or decreased by exchanging the rice planting work device 12 with a different model or changing the number of planting rows of the rice planting work device 12 during the rice planting work. In particular, since the number of rice paddies can be arbitrarily changed by the worker according to the situation during the work, the operation state information 332 is changed at any time during the work following the manual operation of the worker. The work area identification unit 224 always acquires the latest work width information 331 and operation status information 332 by communicating with the rice transplanter side control unit 14 via the communication unit 24, and immediately reflects the change in these information. The width of the area recognized as the work area is determined.

When the work area identification unit 224 identifies that the rice planting work has been duplicated with respect to the existing work area 341, the area is identified as the overlap area 343. The display control unit 23 displays the overlapping area 343 in a color (for example, red) different from that of the worked area 341 and the unworked area 342.

Next, the automatic traveling mode by the traveling control unit 15 of the rice transplanter 1 will be described. In a paddy field, the rice transplanter 1 alternates between a work running Rw that involves rice planting work along a straight row planting route and a ridge turning running Rt for moving to the next row planting route near the ridge. Repeat to. In the automatic running mode, of these two modes of running, steering for linear work running Rw can be automated. In order to use the automatic driving mode, the operator must first register the reference line in the manual driving mode. In the state where the reference line is not registered, the start point registration icon 35A, the end point registration icon 35B, and the automatic driving start icon 35C are all displayed in gray on the touch panel 21.

When the rice transplanter 1 reaches the start point Ts of the reference line located near the shore, when the start point registration icon 35A displayed on the touch panel 21 is touched, the own machine position information 31 when the icon is touched is the reference line start point. The information 36A is registered, and the start point registration icon 35A is changed to a colored display. Subsequently, the rice transplanter 1 is run straight (Rw0) from the start point Ts of the reference line along the straight line shape near the shore, and when the end point Tf of the reference line is reached, the end point registration icon 35B displayed on the touch panel 21 is displayed. When touched, the own machine position information 31 when the icon is touched is registered as the reference line end point information 36B, and the end point registration icon 35B is changed to a colored display. The registration of the reference line is completed by the above operation, but the operator is in a state where the registration of the reference line is completed by visually observing that the start point registration icon 35A and the end point registration icon 35B are colored. Can be easily recognized.

After the registration of the reference line is completed, the ridge turning Rt for moving to the planting route adjacent to the reference line is performed. In this embodiment, an embodiment in which the ridge turning Rt is performed in the manual mode will be described as an example.

When the ridge turning Rt is performed, the rice transplanter 1 enters the row planting route adjacent to the reference line. When the rice transplanter 1 is continuously driven in a straight line in the manual operation mode, the travel control unit 15 determines whether or not to shift to the automatic travel mode based on the preset conditions during the straight line travel. The conditions are, for example, that the steering angle of the steering wheel is within a preset range, and that the route parallel to the reference line is continuously traveled in a straight line over a preset distance. If it is determined that these conditions are satisfied and the transition to the automatic driving mode is possible, the automatic driving start icon 35C is changed to the colored display. The automatic driving start icon 35C is set to receive an operation only in the colored display state, and when the operator touches the automatic driving start icon 35C in the colored state, the traveling control unit 15 shifts to the automatic driving mode. be able to. In this way, whether or not the transition condition to the automatic driving mode is satisfied by the display state of the gray display or the colored display of the start point registration icon 35A, the end point registration icon 35B, and the automatic driving start icon 35C, and The operator can visually recognize which condition is left to achieve the transition condition.

In addition to the icons 35A to 35C, the characters "reference line", "handle", and "straight running" (not shown) are displayed, and when these characters satisfy the conditions corresponding to each character, It may be configured to be colored and grayed out when it is not filled. In particular, the steering angle of the steering wheel and the conditions for straight running may be in a state where the conditions are temporarily satisfied, but the conditions may not be satisfied again due to subsequent steering. It is preferable that the achievement status of each condition can be immediately recognized by such a configuration. According to such a configuration, the operator can adjust the steering so as to achieve the condition that has not been achieved, so that the transition to the automatic driving mode can be smoothly performed.

When the mode shifts to the automatic traveling mode, the rice transplanter 1 is automatically controlled to perform a linear working traveling Rw without an operator performing an artificial operation. Further, in the automatic traveling mode, the display control unit 23 displays the movement direction information 321 on the touch panel 21. By displaying the movement direction information 321 the operator can immediately recognize when the direction in which the rice transplanter 1 travels deviates in the automatic traveling mode, and an artificial operation for correction can be performed. ..
