(Monitor system)
FIG. 3 is a system configuration diagram of the monitor display device. The monitor display device includes a device control controller 41 as a control unit that processes the monitor display information of the combine, and a meter panel 2 incorporating a monitor display unit 2d that receives the monitor display information and outputs an image. .

  Specifically, in addition to the various functions for controlling the equipment of the combine, the equipment control controller 41 serves as a monitor display control device, a monitor communication means 41c for performing data communication with the meter panel 2, a monitor display section In addition to the monitor display detection means 41m for determining the screen switching condition of 2d, the travel distance detection means 41d for calculating the remaining cutting distance up to the full amount of the Glen tank, the timer count detection means 41t for counting the time, etc. The

  On the input side of the device control controller 41 as a monitor display control device, the first to fifth eyelid sensors 42 for detecting the storage amount from the first stage to the fifth stage (full amount), the left and right for detecting the uncut shears In response to instrument signals such as the cereal sensor 43, the mowing monolever 5d, the discharge clutch sensor 44, the HST sensor 5c, the vehicle speed sensor 45, and the engine rotation sensor 46, the meter panel 2 is connected to the output side to display monitor display information. By transmitting, a monitor display device for performing monitor display according to a predetermined display condition is configured.

  In addition to the monitor display unit 2d using a liquid crystal display or the like, the meter panel 2 includes an image control unit 2p for image configuration processing for the display, and displays the monitor display information received from the device control controller 41 as an image. For example, as shown in the screen switching display configuration in FIG. 4, the vehicle speed (0.9 km / h in the example) and the soot storage amount (in the example in FIG. 4) corresponding to the third soot sensor 42 are shown. When the device control controller 41 determines that the soot priority display, the soot storage amount is displayed alone (b) or the soot storage amount is enlarged (c).

  As shown in the flowchart of FIG. 5, the detailed monitor display control in the device controller 41 is a two-condition determination process step 1 in which the engine speed is being output when the engine speed exceeds a predetermined value and the discharge clutch is “ON”. , 2 (denoted as “S1, S2” in the following), or the determination of three conditions when the mowing monolever “ON”, the aircraft is running, and the grain sensor is not “ON” For both cases corresponding to the processes (S3 to S5), the soot sensor information acquisition process (S6) and the soot sensor information display process (S7) are performed.

  With respect to the determination while the vehicle is traveling, it is determined that the vehicle speed sensor exceeds a predetermined value or the HST corresponds to work traveling by a forward operation, and the above two conditions (S1, S2) or three conditions (S3 to S3) are determined. By the determination process of S5), the dredging storage amount is forcibly displayed alone for a specific work situation such as during auger discharge work or during retraction work during the harvesting travel.

  Except for the above case, the display switching operation detection process (S11) is followed by a display switching “present” determination process (S12). If applicable, in order to display the corresponding device information, A sensor information display cancellation process (S13) and a display information set process (S14) are performed. That is, information corresponding to the device status is displayed by the display switching operation detection process (S11), except for a specific work status that is during an auger discharge operation or during a turning run between the harvesting runs.

  With the monitor display control device having the above-described configuration, various types of device information are appropriately provided to the operator who operates the vehicle, and at the time of the turning traveling between the first stroke and the next one, which is a break of the cutting operation Kernel storage information is forcibly displayed. Therefore, important information that is indispensable as a judgment material in the cutting operation is displayed on the monitor with the highest priority in accordance with the required operation timing, so whether or not the next cutting process should be entered, or Thus, it is possible to quickly and accurately determine whether or not to discharge the grain, and to proceed with the cutting work efficiently. For example, even if the Glen tank is not full, if it becomes full in the middle of the next stroke and it is necessary to return to the place of the truck, the kernel is discharged.

  In addition, when dredging is discharged, the grain storage amount information is forcibly displayed in correspondence with the discharging operation by the auger. Therefore, based on the grain storage amount information that is compulsorily displayed without interruption, it is possible to quickly determine the adjustment with the next work plan by estimating the remaining work time. For example, when the truck bed is full and grains remain in the Glen tank, another truck is called.

Next, another screen configuration of the monitor display unit will be described.
FIG. 6 displays the full travel distance alongside the soot storage amount. The full travel distance is the distance that can be harvested until the Glen tank reaches the full capacity, and the amount of dredged storage when it reaches a predetermined dredging amount (fourth stage in the figure) near the full amount shown in FIG.籾 full distance (in the example, “about 12 m”) is displayed, and thereafter, as shown in FIG. The monitor display control device is configured to display “about 3 m”). In this way, it is possible to make an accurate work determination based on the full travel distance displayed side by side with the soot storage amount.

  As shown in the flowchart of FIG. 7, the specific monitor display control of this monitor display control device determines the measurement start condition if the measurement is not being performed by the determination process (S21) regarding the full distance measurement, If the tank storage amount reaches a predetermined amount near the full amount, that is, if the result is determined by the determination process (S22) for the fourth tank sensor “ON”, a predetermined remaining remaining travel distance is set. A possible travel distance setting process (S23) and a full travel distance measurement start process (S24) are performed.

During the full distance measurement, including the above distance measurement start, the travel distance acquisition process (S25) by the vehicle speed sensor is performed, and the detection process subtraction process (S26) for subtracting the travel distance from the possible travel distance is possible. A distance display process (S27) is performed. For the subtraction of the travel distance, the travel distance in the next “on” state of the wheat straw sensor is used.
Next, the soot storage amount is displayed by performing the soot sensor information display process (S28) including the case where the predetermined soot amount near the full amount has not been reached.

(Auger monitor system)
Next, the monitor display related to the auger operation will be described.
As shown in FIG. 8, the monitor display system related to the auger operation includes an auger control device 51 including a monitor display detecting means 51m, a radio control input means 51r, etc. in addition to the monitor communication means 51c similar to the above. It is configured to display necessary information on the monitor screen of the meter panel 2 in accordance with the operation signal.

  On the input side of the device controller 51, signals of an auger automatic storage switch 52a, an auger automatic extension switch 52b, an auger automatic stop switch 53a, and an auger automatic discharge switch 53b are arranged as a group of auger operation switches arranged on the combine cab. In addition to the above, as a signal group by the radio control operation inputted through the auger control unit 61, an auger up / down operation signal 62, an auger left / right operation signal 63, an auger expansion / contraction operation signal 64, an auger automatic turning signal 65, an auger automatic discharge signal 66a. The auger automatic stop signal 66b is received.

The device controller 51 controls display of the monitor screen according to these operation signals.
When a radio control operation is performed, “radio control operation in progress” or “control operation in radio control” is displayed on the monitor. Further, as shown in FIG. 9, the operation content is specifically displayed. With such a monitor display, it is possible to prevent a situation in which a person other than the operator is confused by an unintended auger operation and causes confusion when performing a radio control operation.

Specifically, when the zoom expansion / contraction operation signal 64 is received from the radio control, “zoom expansion” “45%”, “zoom reduction” “60%” in FIG. , Display the auger length expansion and contraction direction by the zoom operation of the radio control.
When the auger up / down operation signal 62 is received from the radio control, the “auger up” and “lower auger” arrows from the “upper auger” and the second lower stage of the example (c, d), As described above, the height position and the operation direction by the vertical operation of the radio control are displayed.
When the auger left / right operation signal 63 is received from the radio control, the left and right operation of the radio control is performed as in the “auger left” and auger left turning arrows, “auger right” and auger right turning arrows in the examples (e, f). Displays the direction of movement.
When an auger stowage or auger overhang signal is received from the radio control, “auger stowage” “return” and auger left turn arrows, “auger overhang” “out” and auger right turn in the examples (g, h) As indicated by the arrow, the direction of operation of the radio-controlled storage overhang operation is displayed.
When the auger automatic discharge signal 66a and the auger automatic stop signal 66b are received from the radio control, the operation of the radio control is performed as shown by “籾 discharge” and the arrow indicating soot discharge in the example (j, k), “saddle discharge stop”. Display the contents.
When an automatic auger storage operation signal is received during discharge, “Discharge!” And “Automatic storage / extension not possible” are displayed alongside the load level display (example of the third step) in the example (m). When a warning is displayed and a discharge signal is received during automatic storage / extension of the auger, along with the weight level display (example of the third stage) in the example (n), “Automatic storage / extension! "Attention cannot be given by displaying" Cannot eject ".

In addition to the above, in an auger device that checks the turning during the discharge operation based on the discharge clutch sensor signal, when the automatic clutch or automatic extension operation signal is received under the detection of the discharge clutch "ON" “Middle” or “Automatic turn impossible” is displayed with caution.
In the conventional auger device, since the auger automatic turning cannot be performed if the turning clutch is restrained due to the trouble of the discharge clutch sensor, this may be mistaken as a trouble related to the auger automatic, resulting in confusion. The situation can be accurately grasped by the monitor display, and such a situation can be avoided.
