  Modes for carrying out the present invention will be described.

(First embodiment)
FIG. 1 is a first block diagram of a first embodiment of the display system for agricultural work machines of the present invention.

  The agricultural working machine display system according to the first embodiment is a system applicable to the display device 11 mounted on the tractor 1, and includes a communication conversion device 12, a control unit 21, a sensor 22, and an actuator 23. The display device 11 and the communication conversion device 12 are provided on the tractor 1 side, and the control unit 21, the sensor 22, and the actuator 23 are provided on the agricultural work machine 2 side attached to the tractor 1. In addition, it can be applied even when the agricultural working machine 2 does not include the actuator 23.

  The display device 11 is a display device mounted on the tractor 1 at a position where the driver can easily see it, and includes a display screen made of liquid crystal, organic EL, LED, or the like. The display device 11 has a configuration capable of introducing an application (application software) and performing a process described later. The display device 11 is connected to the communication line 15, and the end of the communication line 15 on the opposite side of the display device 11 is a connector 15a. The display device 11 can acquire information from the control unit 21 and display the state of the agricultural work machine 2. Further, the display device 11 can display a screen for operating the actuator 23 of the agricultural work machine 2. Applications for these are installed in the display device 11. In addition, the display device 11 may adopt a touch panel method for easy operation. When the touch panel is not used, the operation unit is provided near the screen. As the display device 11, a device that displays the control content of the tractor 1 can be applied.

  The communication conversion device 12 is capable of mutually converting different types of communication and has a configuration capable of performing the processing described below. The communication conversion device 12 is capable of wireless communication with the control unit 21 and is connected to the display device 11 by wire. The end of the communication line 16 connected to the communication conversion device 12 on the opposite side (to the communication conversion device 12) is a connector 16a. Here, different protocols are used for the communication of the wireless communication and the communication of the communication line 16, and the communication conversion device 12 can convert the information by the protocol of the wireless communication into the protocol of the communication line 16, Information based on the protocol can be converted into a wireless communication protocol. Here, as a protocol for wireless communication between the communication conversion device 12 and the control unit 21, for example, BLE (Bluetooth Low Energy) can be applied. Further, the communication conversion device 12 can be activated by an external power supply (for example, DC 12V) of the tractor 1.

  By connecting the connector 15a of the communication line 15 connected to the display device 11 and the connector 16a of the communication line 16 connected to the communication conversion device 12, the display device 11 and the communication conversion device 12 are connected by wire. It As a communication protocol between them, CAN (Controller Area Network) can be applied, for example. Here, as the communication line 16 and the connector 16a, a communication line and a connector corresponding to a protocol applicable to the display device 11 are prepared.

  The control unit 21 is capable of wireless communication with the communication conversion device 12 and controls the transmission of the information of the sensor 22 and the information calculated based on the sensor 22 to the communication conversion device 12. Further, the actuator 23 is also controlled. The control here can be performed based on the information input by the sensor 22 and the display device 11. Further, it may have a storage unit for storing data necessary for control as needed. The control unit 21 includes an electronic device or the like required for control and the like.

  The sensor 22 is a sensor installed on the farm work machine 2 side, and various types of sensors are applied depending on the needs of the farm work machine. The sensor 22 is, for example, an acceleration sensor, an angular velocity sensor, a tilt sensor, a geomagnetic sensor, a rotation sensor, a potentiometer, a limit switch, or the like. This makes it possible to detect the tilt of the agricultural work machine 2, the working depth, the state of the agricultural work machine 2 by the actuator 23, and the like.

  The actuator 23 is an actuator for moving a part of the agricultural working machine 2 as needed. The actuator 23 is, for example, a cylinder such as a hydraulic cylinder or an electric hydraulic cylinder, a motor, or the like. In particular, by using an actuator that moves the position of the working unit of the agricultural work machine 2 that performs agricultural work, it is possible to control this and improve workability of agricultural work.

  FIG. 2 is a first plan schematic view of the first embodiment of the agricultural working machine display system of the present invention. FIG. 3 is a rear view of an agricultural working machine applied in the first embodiment of the agricultural working machine display system of the present invention. The farm work machine 2 of FIGS. 2 and 3 shows an embodiment in which a scraping work machine 30 having a folding mechanism is used. Hereinafter, the traveling direction of the scraping work machine 30 is described as the forward direction. The horizontal direction in FIG. 2 is the lateral direction, and the vertical direction in FIG. 2 is the front-back direction. The horizontal direction in FIG. 3 is the horizontal direction, and the vertical direction in FIG. 3 is the vertical direction of the scraping work machine 30.

  As shown in FIG. 2, the central working unit 35 of the scraping working machine 30 is mounted behind the tractor 1. The side working parts 35 ′ installed on both sides of the central working part 35 are foldable with respect to the central working part 35. A display device 11 is provided near the front side of the driver's seat of the tractor 1, and is connected to the communication conversion device 12 via communication lines 15 and 16. By installing the communication conversion device 12 behind the driver's seat of the tractor 1, the communication distance with the control unit 21 can be shortened. The control unit 21 is installed in the central working unit 35. Moreover, the sensor 22 and the actuator 23 are installed in a suitable place of the scraping work machine 30 according to the application.

  Here, the information from the control unit 21 is sent to the communication conversion device 12 by wireless communication, the communication protocol is converted by the communication conversion device 12 and sent to the display device 11 via the communication lines 15 and 16. Examples of the conversion here include conversion from BLE to CAN. BLE has an effect of enabling low-power communication in wireless communication, and CAN is highly versatile because it is a protocol widely used in tractors. On the other hand, the information from the display device 11 is sent to the communication conversion device 12 via the communication lines 15 and 16, and the communication conversion device 12 converts the communication protocol system to be sent to the control unit 21 by wireless communication. The conversion here is the reverse of the above. For example, conversion from CAN to BLE or the like.

  FIG. 3 shows a specific shape of the substitute scraping work machine 30. The central working unit 35 is provided with a mast 31a that is a mounting unit 31 and left and right hitches 31b, and the substitute scraping work machine 30 is mounted on the tractor 1 via these. The power from the tractor 1 is input through an input shaft provided on the front side, and the cultivating section including the scraping claws is rotated inside the cover 32 and the first ground leveling body 33 behind the cover 32 to make the soil fine. Then, the surface of the soil is made flat by the first leveling body 33 and the second leveling body 34 provided behind it. In this way, the scraping work is performed. Further, the control box 38 is provided on the side surface of the mast 31a, and the control unit 21 is installed inside. As a result, wireless communication with the communication conversion device 12 can be performed near the tractor 1 and at a high position. Note that, for example, the sensor 22 such as a sensor capable of detecting the tilt can be installed in the control box 38. It should be noted that the control box 38 may be installed on the cover 32 or on another frame where vibration is small.

  As the left and right electric hydraulic cylinders 36 expand and contract, the turning mechanism 37 is actuated so that the side working parts 35 ′ provided on the left and right end sides of the central working part 35 can be respectively folded inside. The overall width of the scraping work machine 30 can be shortened. The left and right extended ground leveling body drive devices 40 can rotate the left and right extension ground leveling bodies 41 about the rotation shafts 41a through the arms 42 and the wires 43 by the rotation of the internal motors. Thereby, it is possible to select whether to extend the extended leveling bodies 41 provided at both end portions of the second leveling body 34 to the outside or to fold the inside. The second ground leveling body drive device 46 rotates the second ground leveling body 34 through the second ground leveling body link means 47 by the rotation of the internal motor, and brings the second ground leveling body 34 into the earth pulling state in which it is fixed on the lower side. Alternatively, it is possible to select a normal scraping state in which the rotation is not fixed. The second leveling body drive device 46 can be provided in the control box 38 or adjacent to the control box 38.

  The electric hydraulic cylinder 36, the extension ground leveling body driving device 40 (motor thereof), and the second ground leveling body driving device 46 (motor thereof) can be applied as the actuator 23.

  FIG. 4 shows an example of a screen display for device search of the first embodiment of the display system for agricultural work machines of the present invention. As described above, the communication conversion device 12 and the control unit 21 perform wireless communication, but there may be a plurality of communication radio waves from devices based on the same communication protocol and reception is possible. At this time, as shown in FIG. 4, a plurality of receivable radio waves are displayed on the display screen 11a of the display device 11. Then, the worker can connect to the control unit 21, which is the device to be connected, by performing an operation of selecting an appropriate target from these. For example, in the case of Bluetooth, a list of Bluetooth compatible devices that can be paired is detected and displayed. In FIG. 4, since three types of “WRZ1001”, “WRZ1002”, and “WLZ1001” are displayed, the operator can select, for example, by touching the display portion of “WRZ1001”.

  FIG. 5 shows a display example of the work state on the display device of the first embodiment of the agricultural working machine display system of the present invention.

  The state of the scraping work machine 30, which is the agricultural work machine 2, can be displayed on the display screen 11 a of the display device 11. Here, the versatility can be improved by displaying the state of the substitute scraping work machine 30 by arranging the blocks for each type of state. Specifically, on the display screen 11a, two blocks of a horizontal state display 50 and a depth state display 60 are displayed along the horizontal direction which is the longitudinal direction of the display screen 11a. Displaying a title or frame on each block makes it easier to understand.

Further, by touching the extended leveling body display (left side) 56e or the extended leveling body display (right side) 56f with respect to the left and right extended leveling bodies 41 as well, the target extended leveling body drive device 40 is controlled. It is possible to control opening and closing, and to turn off these displays when closed. As described above, in the horizontal state display 50, the display and the operation can be interlocked with each other. The actuator 23 touches a portion to be moved to perform the operation, and the display content is adjusted according to the state of the agricultural work machine 2 changed by the actuator 23. Can be changed.

  FIG. 7: shows another example of the horizontal state display of 1st Embodiment of the display system for agricultural implements of this invention.

  FIG. 7 shows a state in which the substitute scraping implement display 56k is tilted to the lower right as compared with the horizontal state display 50 shown in FIG. In FIG. 5, the substitute scraping implement display 56k shows a horizontal state, and the horizontal direction of the substitute scraping implement display 56k is parallel to the horizontal line display 56j. At this time, the numerical values of the numerical value display (left side) 58a and the numerical value display (right side) 58b are both "0", and the graduation display 58c also shows only one graduation at the reference position. On the other hand, in FIG. 7, the substitute scraping work machine display 56k in the diagram display 56 is displayed tilted to the lower right. The degree of inclination can be displayed as an inclination according to the actual degree of inclination of the scraping work implement 30. At this time, “2” is displayed on the numerical display (right side) 58b of the state display 58, which means that the integer value of the inclination is 2 °. Nothing is displayed on the numerical display (left side) 58a. Further, the scale display 58c indicates the state below the decimal point, and the scale is increased on the side inclined downward from the reference position which is the center of the left and right. In the example of FIG. 7, one graduation display of the graduation display 58c is shown every 0.2 °, and four graduations are displayed on the right side. Therefore, in FIG. 7, it is shown that the lower right portion is inclined in the range of 2.8 ° or more and less than 3.0 °.

  The degree of inclination can be measured by a sensor 22 (for example, an inclination sensor, an acceleration sensor, or the like) provided on the side of the scraping work machine 30 inside the control box 38 or the like. This information is sent from the control unit 21 to the display device 11 via the communication conversion device 12.

  As described above, in the horizontal state display 50, by actually inclining the display of the substitute scraping work machine display 56k in the diagram display 56, the inclination is displayed in an intuitive manner. Further, in the status display 58, the actual degree of inclination can be displayed in an easy-to-understand manner by displaying the numerical value and the scale.

  FIG. 8: shows the example of the depth state display of 1st Embodiment of the display system for agricultural implements of this invention.

  FIG. 8 shows an example in which the working depth of the substitute scraping implement display 66g is shallower than that of the depth state display 60 shown in FIG. In FIG. 5, the substitute scraping work machine display 66g shows the state at the reference depth, and the numerical value display (upper side) 68a and the numerical value display (lower side) 68b are both "0", and the scale display 68c is also shown. Only one scale of the reference position is displayed. On the other hand, in FIG. 8, the position of the tilling surface display 66f in the drawing display 66 is raised, and the position is close to the rice field display 66e. At this time, the positions of the tilling part display 66d and the cover display 66a are also raised accordingly, and the first leveling body display 66b is displayed by rotating downward about the fulcrum on the cover display 66a side. It should be noted that this position can be displayed according to the degree of movement of the actual position of the scraping work machine 30. Further, in the numerical display (upper side) 68a of the state display 68, "2" is displayed, which means that the integer value of the inclination on the front side is 2 °. Nothing is displayed on the numerical display (lower side) 68b. Further, the scale display 68c indicates a state below the decimal point, and the scale is increased on the side moving from the reference position of the vertical center. In the example of FIG. 8, one graduation display of the graduation display 68c is shown every 0.2 °, and four graduations are displayed on the upper side. For this reason, FIG. 8 shows that it is moving in the shallow direction by inclining to the front side in the range of 2.8 ° or more and less than 3.0 °. This is because the agricultural work machine 2 mounted on the tractor 1 normally utilizes the property of tilting forward because of the structure of the connecting portion when moving upward with respect to the tractor 1. When the reference angle is 0 °, the farming machine 2 is shallower if it is a forward tilt angle and deeper if it is a backward tilt angle. This makes it possible to indicate the degree of depth.

  The degree of inclination can be measured by a sensor 22 (for example, an inclination sensor, an acceleration sensor, or the like) provided on the side of the scraping work machine 30 inside the control box 38 or the like. This information is sent from the control unit 21 to the display device 11 via the communication conversion device 12.

  As described above, in the depth state display 60, the current state is displayed in an intuitively easy-to-understand manner by actually changing the depth of the substitute scraping implement display 66g in the diagram display 66. Further, in the status display 68, the actual depth degree can be displayed in an easy-to-understand manner by displaying numerical values and scales.

  FIG. 9: shows the example of the flowchart in the control part of 1st Embodiment of the display system for agricultural implements of this invention. Here, the processing of the control section 21 on the side of the scraping work machine 30, which is the farm work machine 2, is shown.

  When the power is turned on (S101), a connection standby state is set (S102). Connection standby here means waiting for connection by wireless communication, and is a state in which radio waves for connection standby are being emitted.

  Next, it is determined whether or not a pairing request is received (S103), if the pairing request is not received, the connection standby of S102 is continued, and if the pairing request is received, the pairing is completed (S104). ). The pairing is a pairing with the communication conversion device 12, and is performed by receiving a pairing request (S205 of FIG. 10 described later) from the communication conversion device 12.

  Next, it is determined whether or not the pairing release is received (S105), if the pairing release is received, the process returns to the connection standby of S102, and if the pairing release is not received, the process goes to S106. Here, the pairing cancellation request is also sent from the communication conversion device 12.

  In S106, it is determined whether or not the rewriting signal of the setting data is received. The setting data rewriting signal is a signal sent through the communication conversion device 12 by the operation of the display device 11. For example, it is a signal based on the operation shown in FIG.

  When it is determined that the setting data rewriting signal is received in S106, the setting data is rewritten (S107) and output to the actuator (S108). That is, when the control unit 21 receives the signal transmitted based on the operation on the display device 11 (S209 in FIG. 10, which will be described later), the control unit 21 controls the actuator 23 (for example, the electric hydraulic cylinder 36 or the like). To operate. If it is determined that the rewriting signal of the setting data is not received in S106, the process proceeds to S109.

  In S109, it is determined whether or not the measurement data has been updated. The measurement data is, for example, data measured by the sensor 22 installed on the side of the scraping work machine 30 or data calculated using these. When the measurement data is updated, the measurement data is rewritten (S110), and the rewritten data is output (S111). If the measurement data is not updated, the previous data that has not been rewritten is output (S111). The data output in S111 is performed to the communication conversion device 12, and the communication conversion device 12 determines whether or not the data is received from the control unit 21 (S210 in FIG. 10, which will be described later). After the data output in S111, the process returns to S105.

  FIG. 10: shows the example of the flowchart in the communication converter of 1st Embodiment of the display system for agricultural implements of this invention. Here, the processing of the communication conversion device 12 arranged on the tractor 1 side is shown.

  When the power is turned on (S201), it is determined whether a device waiting for connection has been detected (S202). Here, the device waiting for connection can be detected by the control unit 21 when the device is waiting for connection in S102 of FIG. When a device waiting for connection is detected in S202, the device waiting for connection is output to the display device 11 (S203). Based on this output, the devices waiting for connection are displayed on the display device 11 (S303 in FIG. 11, which will be described later).

  Next, it is determined whether a pairing request has been received (S204). The determination here is made based on whether or not the pairing request (S305 in FIG. 11, which will be described later) transmitted from the display device 11 is received. When the pairing request is not received, the process returns to S202, and when the pairing request is received, the pairing request is transmitted to the requested device (S205). The transmission of this pairing request is to the control unit 21, and the control unit 21 determines whether or not the pairing request has been received based on this (S103 in FIG. 9).

  Next, it is determined whether the pairing is successful (S206). If the pairing is not successful, the process returns to S202, and if it is determined that the pairing is successful, the pairing completion information is output (S207). The output here is performed to the display device 11, and the display device 11 determines based on this whether or not the pairing is successful (S306 in FIG. 11 described later).

  Next, it is determined whether data has been received from the display device 11 (S208). The determination here is made based on whether or not the data output from the display device 11 (S309 in FIG. 11, which will be described later) is received. If it is determined that the data is not received, the process proceeds to S210, and if it is determined that the data is received, the data is transmitted to the control unit 21 (S209). At this time, the communication protocol of the data used in the communication between the communication conversion device 12 and the display device 11 is changed to the communication protocol of the data used in the communication between the communication conversion device 12 and the control unit 21 and transmitted. The control unit 21 determines whether or not the data is received based on the transmitted data (S106 in FIG. 9).

  Next, it is determined whether data is received from the control unit 21 (S210). The determination here is made based on whether or not the data (S111 in FIG. 9) output from the control unit 21 has been received. If it is determined that the data is not received, the process proceeds to S211, and if it is determined that the data is received, the data is transmitted to the display device 11 (S212). At this time, the communication protocol of the data used in the communication between the communication conversion device 12 and the control unit 21 is changed to the communication protocol of the data used in the communication between the communication conversion device 12 and the display device 11 and transmitted. Based on the transmitted data, the display device 11 determines whether or not the data is received (S310 in FIG. 11, which will be described later). After S212, the process returns to S208.

  In S211, it is determined whether or not data has been received within a fixed time. Then, when the data is not received within the fixed time, the process returns to S202. In the state of S202, the communication interval can be reduced and the power saving mode can be set, as compared with the states of S208 and S210, so that wasteful power consumption of the communication conversion device 12 can be suppressed.

  FIG. 11: shows the example of the flowchart in the display apparatus of 1st Embodiment of the display system for agricultural implements of this invention. Here, the processing of the display device 11 arranged on the tractor 1 side is shown.

  The display device 11 activates an application that enables the processing (S301).

  Next, the device search is started by the operator's operation or automatically (S302), and the device waiting for connection is displayed on the display screen 11a of the display device 11 (S303). The information of the device waiting for connection here is output from the communication conversion device 12 (S203 in FIG. 10). The display example here is as shown in FIG.

  Next, the device to be connected is selected (S304). The selection here can be performed by the operator touching the touch panel of the display screen 11a or the like.

  Next, a pairing request is transmitted (S305). A pairing request is transmitted to the communication conversion device 12 for the device selected in S303. Based on this, the communication conversion device 12 determines whether or not the pairing request has been received (S204 in FIG. 10).

  Next, it is determined whether the pairing is successful (S306). This determination can be made based on the pairing completion information from the communication conversion device 12 (S207 in FIG. 10). When it is determined that the pairing is not successful, the process returns to S302, and when it is determined that the pairing is successful, the work screen is displayed on the display screen 11a (S307). The display here is, for example, a display of the work state such as the horizontal state display 50 and the depth state display 60 shown in FIG. Initially, the reference state may be displayed as shown in FIG.

  Next, it is determined whether or not a setting input has been made (S308). The setting input here is when there is some input on the display device 11, and is, for example, the input of the setting by touching the touch panel of the display screen 11a. As described with reference to FIGS. 5 and 6, it is also possible to touch a part of the graphic display 56 and use it as an input for changing the setting. If there is no setting input in S308, the process proceeds to S310, and if there is a setting input, the input setting data is output (S309). The output here is output to the communication conversion device 12. Based on this, the communication conversion device 12 determines whether or not data has been received from the display device 11 (S208 in FIG. 10).

  Next, it is determined whether data has been received (S310). The data here is the data transmitted from the communication conversion device 12 (S212 in FIG. 10). The data here is, for example, information based on the sensor 22 of the substitute scraping work machine 30 (agricultural work machine 2). Then, when it is determined that the data is not received, the process proceeds to S311. When it is determined that the data is received, the screen is updated (S312) and the process returns to S308. As an example of updating the screen, it is possible to change the horizontal state display 50 and the depth state display 60 of FIG. 5 according to the data based on the sensor 22 as shown in FIGS. 7 and 8.

  In S311, it is determined whether or not data is received within a fixed time. Then, if the data is not received within the fixed time, it is determined that the communication is disconnected, the process returns to S302, and the pairing is performed again. In the state of S302, the communication interval can be reduced and the power saving mode can be set, as compared with the states of S308 and S310, so that useless power consumption of the display device 11 can be suppressed.

  As described above, in the first embodiment, the display device 11 mounted on the tractor 1 makes it possible to easily understand and perform the operation and the state of the agricultural work machine 2. Furthermore, the versatility can be increased by converting the communication protocol using the communication conversion device 12 for the display device 11 mounted on the tractor 1. In particular, the display device 11 and the communication conversion device 12 can be connected to the display device 11 through communication by using CAN widely used for tractors, even if the manufacturers and vehicle types are different. In addition, by setting BLE between the control unit 21 and the communication conversion device 12, it is possible to perform communication with low power and, as described later, versatility with a general portable device such as a smartphone. Can be increased. In addition, since wireless communication is performed between the communication conversion device 12 and the control unit 21, when attaching or detaching the agricultural work machine 2 to or from the tractor 1, there is no need to connect wiring for communication, so that labor is saved. It is possible to prevent wiring damage such as disconnection due to a work mistake.

  FIG. 12 is a second block diagram of the first embodiment of the agricultural-working machine display system of the present invention. FIG. 13 is a second schematic plan view of the first embodiment of the display system for agricultural work machines of the present invention.

  The agricultural working machine display system of the first embodiment can be configured as a system applicable to the communication terminal 81 in addition to the display device 11 mounted on the tractor 1 shown in FIGS. This is shown in FIGS. 12 and 13, and since the communication terminal 81 is a portable terminal, it can be arranged in the tractor 1. Further, the control unit 21, the sensor 22, and the actuator 23 are the same as those shown in FIGS. 1 and 2 and the like, which are provided in the agricultural work machine 2 (scraping work machine 30).

  The communication terminal 81 is a portable terminal having a wireless communication function, and includes a display screen 81a made of liquid crystal, organic EL, LED or the like. Further, the communication terminal 81 has a configuration capable of introducing an application and performing the same processing as that of the display device 11 described above. Further, in order to facilitate the operation, the display screen 81a of the communication terminal 81 can adopt a touch panel system. As the communication terminal 81, a general-purpose communication terminal can be preferably applied. For example, it is a smartphone or a tablet computer.

  The communication terminal 81 and the control unit 21 are capable of wireless communication. The wireless communication between the communication terminal 81 and the control unit 21 is based on the same protocol as the wireless communication between the communication conversion device 12 and the control unit 21 described in FIGS. For example, BLE can be applied. Since the same communication type is adopted, the data transmitted from the control unit 21 and the data received by the control unit 21 can be the same in the examples of FIGS. 1 and 2 and the examples of FIGS. 12 and 13. ..

  FIG. 14 shows a display example of the work status on the communication terminal of the first embodiment of the agricultural working machine display system of the present invention.

  In FIG. 14, on the display screen 81a of the communication terminal 81, two blocks of the horizontal state display 50 and the depth state display 60 described in FIG. 5 are displayed side by side in the vertical direction. This is different from FIG. 5 in that the longitudinal direction of the display screen 81a is the vertical direction, and therefore the sensor in the communication terminal 81 senses this and displays it accordingly. This can be displayed by a process in the communication terminal 81. When the longitudinal direction of the communication terminal 81 is set to the horizontal direction, the sensor in the communication terminal 81 senses this, and the blocks of the horizontal state display 50 and the depth state display 60 are set to the horizontal direction as in FIG. You may display it side by side.

  Next, processing of the control unit 21 and the communication terminal 81 in the configurations shown in FIGS.

  The control unit 21 of FIGS. 12 and 13 performs the process according to the flowchart of FIG. Here, as compared with the case of the configuration including the communication conversion device 12 and the display device 11 described above, the difference is that data is exchanged not with the communication conversion device 12 but with the communication terminal 81. The other processes in the control unit 21 are basically the same. Hereinafter, the case where the communication terminal 81 is used will be described focusing on the points different from the case where the communication conversion device 12 and the display device 11 are used.

  The pairing in S103 and S104 of FIG. 9 is pairing with the communication terminal 81, and is performed by receiving a pairing request from the communication terminal 81. The request for canceling the pairing in S105 is also sent from the communication terminal 81.

  In the determination of whether or not the setting data rewriting signal is received in S106, the setting data rewriting signal is a signal directly sent from the communication terminal 81 by the operation of the communication terminal 81. For example, it is a signal based on the case where the same operation as that shown in FIG. 6 is performed on the communication terminal 81. Based on this signal, the processes of S107 and S108 are performed.

  The data output in S111 is performed to the communication terminal 81. For example, in the communication terminal 81, the display of FIG. 14 is changed to the display as shown in FIGS.

  The communication terminal 81 of FIGS. 12 and 13 performs processing according to the flowchart of FIG. Here, as compared with the case of the configuration including the communication conversion device 12 and the display device 11 described above, the difference is that data is exchanged not with the communication conversion device 12 but with the control unit 21. The other processes in the communication terminal 81 are basically the same as those in the display device 11. Hereinafter, the points different from the case of the display device 11 will be mainly described.

  In S301 of FIG. 11, the communication terminal 81 activates an application that enables the process.

  In S302 and S303, information on the device waiting for connection is output from the control unit 21 (S102 in FIG. 9) and displayed on the communication terminal 81. The display example is the same as in FIG. In S304, the operator selects a device to connect by touching the touch panel of the display screen 81a or the like.

  The pairing request of S305 is transmitted to the control unit 21. Based on this, the control unit 21 determines whether or not a pairing request has been received (S103 in FIG. 9).

  The determination as to whether or not the pairing in S306 is successful can be made because the communication terminal 81 performs the pairing. The display of the work screen in S307 can be performed on the display screen 81a as shown in FIG. 14, for example. Initially, the reference state as shown in FIG. 14 may be displayed.

  The determination as to whether or not the setting input has been made in S308 is when there is any input to the communication terminal 81, for example, the setting input by touching the touch panel of the display screen 81a. It is also possible to display as shown in FIG. 14 on the display screen 81a and touch a part of the diagram display 56 to make an input for changing the setting as shown in FIG. The output of the setting data in S309 is output to the control unit 21. Based on this, the control unit 21 determines whether or not the setting data rewrite signal has been received (S106 in FIG. 9).

  The determination as to whether or not the data has been received in S310 is performed based on the data (S111 in FIG. 9) transmitted from the control unit 21. The data here is information based on the sensor 22 of the substitute scraping work machine 30 (agricultural work machine 2), for example. The screen of S312 is updated on the display screen 81a. For example, the horizontal state display 50 and the depth state display 60 in FIG. 14 can be changed by the data based on the sensor 22 in the same manner as in FIGS. 7 and 8. The determination of S311 is performed in the communication terminal 81 in the same manner as in the case of the display device 11.

  In this way, the portable communication terminal 81 makes it possible to easily understand and perform the operation and the state of the agricultural work machine 2. Further, also in the case of the communication terminal 81, the versatility can be increased without replacing parts by performing the same control by the control unit 21 as in the case of using the display device 11 and the communication conversion device 12. Further, as shown in FIG. 14, by changing the arrangement of the blocks in the horizontal state display 50 and the depth state display 60, the display size can be reduced and the display can be made easier to see. In addition, by using BLE between the control unit 21 and the communication terminal 81, it is possible to perform communication with low power and use a communication protocol used in a general portable device such as a smartphone. , The range of application can be expanded.

(Second embodiment)
FIG. 15 is a schematic plan view of a second embodiment of the agricultural working machine display system of the present invention. In the second embodiment, the points different from the first embodiment will be mainly described, the same parts are denoted by the same reference numerals, and the same description is omitted for parts that are not particularly described.

One end of the intermediate frame 103 is rotatably connected to the mounting unit 102, and the other end of the intermediate frame 103 is connected to a working unit 105 having a rotating mechanism 104. The working section 105 has a plowing section 107 on the front side and a disk section 108 behind it. The PTO power from the tractor 1 is sent to the working unit 105 via a transmission mechanism (not shown). The working unit 105 has a configuration in which the soil of the old ridge is sent to the disc unit 108 by the rotation of the claw 107a in the cultivating unit cover 107b in the cultivating unit 107, and the rotation of the disc unit 108 shapes the ridge shape into a new ridge shape.

  Further, the ridge coater 100 is provided with a first cylinder 111 and a second cylinder 112. By expanding and contracting the first cylinder 111, the offset amount of the working unit 105 (the position in the lateral direction with respect to the tractor 1) can be adjusted. Further, by fully contracting the first cylinder 111 from the forward working state shown in FIG. 15, the working unit 105 can be offset moved to the center, and the working state can be set. Further, by extending the second cylinder 112 from the retracted state, the working unit 105 is rotated, and the return work is made possible in the back working state. At this time, the working unit 105 projects to the left side opposite to the left and right, and the front and rear of the working unit 105 are reversed. The first cylinder 111 and the second cylinder 112 correspond to the actuator 23 of FIG.

  The control box 110 is attached to the mounting unit 102, and can store the control unit 21, the sensor 22 and the like shown in FIG. Further, the display device 11 and the communication conversion device 12 of the tractor 1 are the same as those in the first embodiment.

  Here, in the ridge coater 100, examples of displaying the working state on the display device 11 include an example of displaying the offset amount of the working unit 105 and an example of displaying the depth of the tilling unit 107 with respect to the disk unit 108. Be done. At this time, similarly to FIGS. 5 to 7, it is possible to display by a diagram or a picture, and display by a numerical value and a scale. Further, when displaying a drawing or a picture corresponding to the ridge coater 100 on the display device 11, touching a portion corresponding to the working unit 105 controls so that the forward working state, the stored state, and the back working state can be respectively changed. May be. The exchange of these data is the same as in the first embodiment. Further, it may be configured to be applicable to the communication terminal 81 as in FIGS.

(Third Embodiment)
FIG. 16 is a schematic plan view of a third embodiment of the agricultural working machine display system according to the present invention. In the third embodiment, the points different from the first embodiment will be mainly described, the same parts are denoted by the same reference numerals, and the same description is omitted for parts that are not particularly described. In this embodiment, an example is shown in which a fertilizer application and seeding machine 200 that performs fertilization and sowing is applied as the agricultural work machine 2. Note that the upper side of FIG. 16 indicates the front side (forward direction of work), the lower side indicates the rear side, and the left-right direction of FIG. 16 indicates the lateral (left-right) direction. Note that in FIG. 16, the illustration of the tractor 1 and the fertilizer-seeding machine 200 is simplified.

  The fertilizer application and seeding machine 200 includes a fertilizer application hopper 201 and a seeding hopper 211 provided behind the fertilizer application hopper 201. At the lower part of the fertilizer application hopper 201, there is a rotary for rotating a tilling part (not shown) to perform tilling. Fertilizer as a content is contained in the fertilizer application hopper 201, and as the fertilizer application motor 202 rotates, the fertilizer is discharged from the lower part of the fertilizer application hopper 201 through the fertilizer application hose to the front side of the tillage section. Further, seeds are contained as contents in the seeding hopper 211, and the seeds are discharged to the rear side of the tilling part through the seed hose as the seeding motor 212 rotates. In FIG. 16, two fertilizer hoppers 201 are installed on the left and right, and six seeding hoppers 211 are installed on the left and right. At this time, the discharge amount of fertilizer in the fertilizer hopper 201 can be changed according to the rotation speed of the fertilizer application motor 202, and the discharge amount of seeds in the seed hopper 211 can be changed according to the rotation speed of the sowing motor 212. it can.

  The control box 220 is attached between the fertilizing hopper 201 and the sowing hopper 211, etc., and can store the control unit 21, the sensor 22 and the like shown in FIG. 1.

Further, the communication conversion device 12 'can be started by an external power source (for example, DC 12V) of the tractor 1.

  The connector 18a at one end of the branch destination of the communication line 18 connected to the communication conversion device 12 'is connected to the connector 17a of the communication line 17 connected to the tractor-side controller 13. Further, the connector 18b at the other end of the branch destination of the communication line 18 is connected to the connector 25a of the communication line 25 connected to the control unit 21 '. As a result, the communication converter 12 ', the controller 21', and the tractor-side controller 13 are connected by wire. As a communication protocol between them, CAN (Controller Area Network) can be applied, for example.

  Information about the tractor 1 is output from the tractor-side controller 13 through the communication line 17. The information output here includes information indicating the current state of the tractor. For example, the current vehicle speed and steering angle of the tractor 1, the position of the agricultural work machine 2 mounted on the tractor 1 with respect to the tractor 1 (height and Information such as angle).

At this time, as shown in FIGS. 5 to 8 and 14, it is possible to perform display by figures or pictures, and display by numerical values and scales. In addition, if the emission amount per unit area is displayed as the emission amount of fertilizer or seed, it becomes easy for the operator to understand. The discharge amount per unit area can be calculated by the control unit 21 'by using the speed of the fertilizer-seeding machine 200 and the discharge amount per time. The speed of the fertilizer application seeder 200 can be measured by providing a sensor capable of measuring the speed as the sensor 22 in the fertilizer application seeder 200. Alternatively, the vehicle speed information can be obtained from the tractor-side controller 13 via the communication line 17, the communication line 18, and the communication line 25. The discharge amount per time can be measured by the number of rotations of the fertilizer application motor 202 and the seeding motor 212. The fertilizer and seed discharge amounts calculated by the control unit 21 'are sent to the display device 11' via the communication line 25, the communication line 18, and the communication conversion device 12 '.

In this case, the connector 17a of the communication line 17 and the connector 25a of the communication line 25 are connected. Even in this state, the control unit 21 'can obtain information from the tractor-side controller 13. Here, the connector 25a of the communication line 25 and the connector 18a at the one end of the branch destination of the communication line 18 have the same shape, and the connector 17a of the communication line 17 and the connector 18b at the other end of the branch destination of the communication line 18 are the same. It is a shaped connector.

  When the power is turned on (S401), it is determined whether or not a setting data rewrite signal is received (S402). The setting data rewriting signal is a signal sent through the communication conversion device 12 'by operating the display device 11'.

  When it is determined in S402 that the setting data rewriting signal is received, the setting data is rewritten (S403) and output to the actuator (S404). That is, when the control unit 21 ′ receives the signal transmitted based on the operation on the display device 11 ′ (S507 in FIG. 20, which will be described later), the control unit 21 ′ causes the actuator 23 (for example, the fertilizer application motor 202, the seeding motor). 212, etc.) to operate. If it is determined in S402 that the setting data rewrite signal is not received, the process proceeds to S405.

  Next, in S405, it is determined whether or not the measurement data has been updated. The measurement data is, for example, data measured by the sensor 22 installed on the farm work machine 2 side, data from the tractor side controller 13 (for example, vehicle speed information), or data calculated using these. When the measurement data is updated, the measurement data is rewritten (S406) and the rewritten data is output (S407). If the measurement data is not updated, the previous data that has not been rewritten is output (S407). The data output in S407 is performed to the communication conversion device 12 ', and the communication conversion device 12' receives the data from the control unit 21 '(S508 in FIG. 20, which will be described later). After the data output in S407, the process returns to S402.

  Next, it is determined whether or not a pairing request is received (S503), if the pairing request is not received, the connection standby of S502 is continued, and if the pairing request is received, the pairing is completed (S504). ). The pairing is a pairing with the display device 11 ', and is performed by receiving a pairing request (S605 in FIG. 21, which will be described later) transmitted from the display device 11'.

  Next, it is determined whether or not the pairing release is received (S505), if the pairing release is received, the process returns to the connection standby of S502, and if the pairing release is not received, the process proceeds to S506. Here, the pairing cancellation request is also sent from the display device 11 '.

  Next, it is determined whether or not data is received from the display device 11 '(S506). The determination here is made based on whether or not the data (S609 of FIG. 21, which will be described later) output from the display device 11 'is received. If it is determined that the data is not received, the process proceeds to S508, and if it is determined that the data is received, the data is transmitted to the control unit 21 '(S507). At this time, the communication protocol of the data used in the communication between the communication conversion device 12 and the display device 11 'is changed to the communication protocol of the data used in the communication between the communication conversion device 12 and the control unit 21' and transmitted. .. The control unit 21 'determines whether or not the data is received based on the transmitted data (S402 in FIG. 19).

  Next, the data is received from the control unit 21 '(S508), and the data is transmitted to the display device 11' (S509). At this time, the communication protocol of the data used in the communication between the communication conversion device 12 'and the control unit 21' is changed to the communication protocol of the data used in the communication between the communication conversion device 12 'and the display device 11'. Send. The display device 11 'determines whether or not the data is received based on the transmitted data (S610 in FIG. 21, which will be described later). After S509, the process returns to S505.

  FIG. 21: shows the example of the flowchart in the display apparatus of 4th Embodiment of the display system for agricultural implements of this invention. Here, the processing of the display device 11 ′ that can be arranged on the tractor 1 side is shown.

  On the display device 11 ', an application that enables the processing is activated (S601).

  Next, the device search is started by the operator's operation or automatically (S602), and the device waiting for connection is displayed on the display screen 11a 'of the display device 11' (S603). The display example here is the same as that in FIG.

  Next, the device to be connected is selected (S604). The selection here can be made by the operator touching the touch panel of the display screen 11a 'or the like.

  Next, a pairing request is transmitted (S605). A pairing request is transmitted to the communication conversion device 12 'for the device selected in S603. Based on this, the communication conversion device 12 'determines whether or not the pairing request has been received (S503 in FIG. 20).

  Next, it is determined whether the pairing is successful (S606). If it is determined that the pairing is not successful, the process returns to S602, and if it is determined that the pairing is successful, the work screen is displayed on the display screen 11a '(S607). The display here is, for example, a display according to the display of the work state such as the horizontal state display 50 and the depth state display 60 shown in FIG. 5, the display of the amount of fertilizer or seed discharge, and the like.

  Next, it is determined whether or not the setting is input (S608). The setting input here is a case where there is some input on the display device 11 ', for example, a setting input by touching the touch panel of the display screen 11a'. Then, if there is no setting input in S608, the process proceeds to S610, and if there is a setting input, the input setting data is output (S609). The output here is output to the communication conversion device 12 '. Based on this, the communication conversion device 12 'determines whether or not data has been received from the display device 11' (S506 in FIG. 20).

  Next, it is determined whether data has been received (S610). The data here is the data transmitted from the communication conversion device 12 '(S509 in FIG. 20). For example, it is information based on the sensor 22 of the farm work machine 2. Then, when it is determined that the data is not received, the process proceeds to S611, and when it is determined that the data is received, the screen is updated (S612) and the process returns to S608. The screen update here is performed based on the received data.

  In S611, it is determined whether or not the data is received within the fixed time. Then, if the data is not received within the fixed time, the process returns to S602. In the state of S602, the communication interval can be reduced and the power saving mode can be set, as compared with the states of S608 and S610, so that useless power consumption of the display device 11 'can be suppressed.

When the pairing completion information (S707 in FIG. 24) output from the communication terminal 81 'is received, it is determined that the pairing is successful, and when not received, it is determined that the pairing is not successful. When it is determined that the pairing is not successful, the process returns to S802, and when it is determined that the pairing is successful, the pairing completion information is output to the display device 11 (S807). Based on this, the display device 11 determines whether the pairing is successful (S306 in FIG. 11).

  Next, it is determined whether data has been received from the display device 11 (S808). The determination here is made based on whether or not the data (S309 of FIG. 11) output from the display device 11 has been received. When it is determined that the data is not received, the procedure proceeds to S810, and when it is determined that the data is received, the data is transmitted to the communication terminal 81 '(S809). At this time, from the communication protocol (second communication protocol P2) of the data used in the communication between the communication conversion device 12 ″ and the display device 11, the communication conversion device 12 ″ is used in the communication between the communication terminal 81 ′. The data communication protocol (third communication protocol P3) is changed and transmitted. Based on the transmitted data, the communication conversion device 12 ″ determines whether or not the data has been received (S <b> 708 in FIG. 24).

  Next, it is determined whether data has been received from the communication terminal 81 '(S810). The determination here is made based on whether or not the data (S712 in FIG. 24) output from the communication terminal 81 'has been received. If it is determined that the data is not received, the process proceeds to step S811, and if it is determined that the data is received, the data is transmitted to the display device 11 (S812). At this time, from the communication protocol (third communication protocol P3) of the data used in the communication between the communication conversion device 12 ″ and the communication terminal 81 ′, the communication conversion device 12 ″ is used in the communication between the display device 11 and the communication device 81 ″. A data communication protocol (second communication protocol P2) is changed and transmitted. The display device 11 determines whether or not the data is received based on the transmitted data (S310 in FIG. 11). After S812, the process returns to S808.

  In S811, it is determined whether or not the data is received within the fixed time. Then, if the data is not received within the fixed time, it is determined that the communication is disconnected, and the process returns to S802. In the state of S802, the communication interval can be reduced and the power saving mode can be set, as compared with the states of S808 and S810, so that wasteful power consumption of the communication conversion device 12 ″ can be suppressed.

  In the display device 11 of the fifth embodiment, processing is performed according to the above-mentioned flowchart of FIG.
