In this configuration, when emergency information with a high degree of need to be notified to the operator during operation of the work machine is generated, the emergency information is given priority to the image display unit displaying the above ordinary telegram or the conveying information in preference to the ordinary information or abnormality information. Since the emergency information is immediately displayed on the image display unit, the operator can take appropriate measures.

Furthermore, in one of the preferred embodiments of the present invention, the abnormality occurrence notification unit also functions as a control state indicator 100 for displaying the operation state and the non-operation state of each of the plurality of control functions relating to the operation of the work machine. Abnormal notification regarding the control function is notified by the corresponding control status indicator. In this configuration, a plurality of control functions are executed to operate the work machine, and the connection cut-off state of the plurality of controls, and eventually the operating state and the non-operating state, are selectively displayed on the control state indicator. If an abnormality of either control function occurs, the control state indicator corresponding to the abnormal control function becomes a display state that indicates an abnormality. In addition, the display instruction can be instructed to display abnormal information on the control on the image display unit for confirmation.

Furthermore, in one of the preferred embodiments of the present invention, a control switching commander for instructing the controller to switch the control function to the operating state or the non-operation state is provided for each of the control functions. The transmission of the abnormality information is stopped by operating the control switching commander for the control function relating to the abnormality information. In this configuration, the occurrence of any abnormality of any of the plurality of control functions is notified by the control state display unit, and for example, the operator instructs the display command to display the abnormal information on the screen of the display unit to display the contents of the abnormal information. After confirming, by operating the control switching commander corresponding to the control function judged to be abnormal, the notification of abnormality by the control state display unit is stopped to return at a time suitable for the normal display of displaying the state of the control function.

Furthermore, in one of the preferred embodiments of the present invention, the display commander is combined with a manual operation commander provided for inputting a normal operation command to the controller, and the display command or the operation command is set by the operation method. It is recognized by the controller. In this configuration, since a display command of the abnormality information can be commanded to the controller using a manual operation commander provided for inputting normal operation information to the controller, a dedicated switch or the like is provided as the display commander. This becomes unnecessary, and the device configuration can be simplified.

The controller CU can execute a plurality of controls (handling depth control, threshing control, vehicle speed control, direction control, cutting height control, rail control, unloader control, horizontal control, etc.) to operate the combine. In addition, a plurality of control state display unit 100 for displaying a connection blocking state of each of the plurality of control, and a plurality of control switching commands for instructing the central control unit (CU) to connect each of the plurality of control The machine 200 is installed.

Specifically, the plurality of control state display units 100 each include the above-described start button 41a for handling depth control, start switch 42a for vehicle speed control, and start switch for direction control, each of which is comprised of an illuminated push button switch. 43a, a start switch 44a for mowing height control, an auto / stop switch 50a for unloader control, an auto switch 60a for starting horizontal control, and a rail control lamp 45b consisting of a single lamp; It is configured by Similarly, the plurality of control switching commanders 200 are the start switch 41a of the handling depth control, the start switch 42a of the vehicle speed control, the start switch 43a of the direction control, and the start switch 44a of the cutting height control. ), Automatic stop switch 50a for unloader control, automatic switch 60a for starting horizontal control, and rail start switch 45a composed of a single switch. Then, in the normal display state in which the connection of control is blocked, the lamp is turned on at the time of the control connection and operated to turn off at the time of the control cutoff.

When the controller CU executes the above-mentioned control, the sensors SW and the switches transmitted from the sub-controllers LU1 to LU5 and the modules MU1 to MU4 through the communication lines T1 and T2 are used. Based on the respective input data of, the appropriate drive contents for the actuators AK are determined, and the appropriate drive contents are the drive data, and the sub-controller LU in which the actuators AK are connected through the communication line T1 is connected. ), And the sub-controller LU to which the actuators AK are connected outputs a drive signal to the actuators AK based on the received drive data.

For example, the concrete case of the cutting height control will be described in detail. The controller CU is provided with a cutting height provided in the cutting height control operation unit 44 by communicating with the basic switch module MU1. When it is determined that the control start switch 44a is turned on, the cutting height is maintained at the target height based on the target height information input to the cutting height adjusting volume 44b and the ground height information of the ultrasonic sensor S6. The proper driving contents for the mowing elevating cylinder 5 are determined, and the appropriate driving contents are transmitted to the sub-controller LU1 to which the mowing elevating cylinder 5 is connected as control data.

The central control unit CU is configured to input data such as sensors SW and switches transmitted from the high speed terminal units LU1 to LU5 and the modules MU1 to MU4 via the communication lines T1 and T2. On the basis of this, the appropriate display contents displayed on various display devices such as the lamp and the LCD display are determined, and the appropriate display contents are transmitted to the respective modules Mu1 to MU4 via the communication line T1 as display data. Each module MU1 to MU4 is configured to output a drive signal to the display device based on the display data received from the controller CU.

The concrete case of the above-mentioned cutting height control will be described in detail. When the controller CU confirms the on state of the starting switch 44a of the cutting height control based on the received data from the basic switch module MU1, The command message for turning on the start switch 44a constituted by the dimming switch is transmitted to the switch module MU1, and the start-up height control start message is sent to the main LCD 70e to the display module MU4. Send a display command to display. Then, the basic switch module MU1 turns on the basic switch 44a for the mowing height control in accordance with the lighting command data received from the controller CU, and the display module MU4 controls the controller CU. In response to the display command received from the above, the main LCD 70e displays a message of " depth height automatic [connection] " for a predetermined time (for example, 5 seconds).

In addition, when the start height switch 44a of the cutting height control is turned off, a message of "automatic cutting height [blocking]" is displayed on the main LCD 70e for a predetermined time (for example, 5 seconds), and the cutting height is set. Even when the adjustment volume 44b is operated and the target height information is changed, the value of the target cutting height changed by the cutting height adjustment volume 44b based on the communication between the controller CU and the display module MU4. This is displayed in the bar graph on the main LCD 70e.

Next, the control operation by the controller CU will be described based on the flowcharts shown in FIGS. 19 to 23.

On the other hand, when the check switch 71 is in the off state, it is started in the normal mode. In this normal mode, the on / off state of the check switch 71 is detected. When the check switch 71 is turned on, the self-diagnosis mode is entered. Is activated.

In the fine adjustment mode, the actual operation state of each machine part from the detection information of each sensor corresponds to the detection information of each sensor when the machine parts such as the harvesting unit 1 and the threshing unit 2 are in the reference state. Information of a reference value (called fine adjustment data) for obtaining the data is stored in the memory MEM.

Specifically, fine adjustment data as exemplified below are stored.

(1) The detected value of each direction sensor S1 at that time, with the state in which the left and right direction sensors S1 return to the gas side direction position as a reference state.

(2) The detection value of the mowing lift detection sensor S1 when the mowing section 1 is raised to the upper limit position as a reference state.

(3) The detection value of the unloader position sensor S3 when the unloader 32 is rotated to the home position as a reference state.

(4) The detection value of the rolling sensor S4 when the gas V is set to the horizontal state as the reference state.

In the normal mode, as shown in Fig. 20, communication control processing for communicating between each subcontroller LU1 to LU5 and each module MU1 to MU4, management processing of the notification information, display control processing, and Job control processing for executing a plurality of controls is performed. Further, in this job control process, the actual operating state of each machine part is obtained based on the detection information of each sensor and the stored fine adjustment data, and the actuators AK are operated based on the information of the actual operating state. To control.

In the display control process, as shown in Figs. 21 to 22, first, it is determined whether the first alarm information is generated or not, and when the first alarm information is generated, the first alarm information is used as the main information. While displaying the LCD 70e continuously, the alarm buzzer 48 and the alarm lamp 49 are continuously operated. Although not shown, at the same time, the stop operation of the engine E is executed in the job control process.

When the first alarm information is not generated, it is determined whether or not the second alarm information is generated, and when the second alarm information is generated, the second alarm information is displayed on the main LCD 70e. At the same time, the alarm buzzer 48 and the alarm lamp 49 are operated simultaneously with the second alarm display. Moreover, the second alarm display is repeatedly displayed at set time intervals (e.g., 30 second intervals).

When the alarm information is not generated, it is judged whether or not self diagnosis data is generated. When the self diagnostic data is generated, the check lamp 70g1 is turned on except when the self diagnostic data is already displayed, and it is determined whether or not the check switch 71 is turned on. When the check switch 71 is turned on, the self-diagnosis data is displayed on the main LCD 70e. When the check switch 71 is turned on again while displaying the self diagnostic data, the check lamp 70g1 is turned off, the display of the self diagnostic data is turned off, and the main LCD 70e displays normal information. Return to the state.

When the first alarm information and the self-diagnosis data are not generated, the main LCD 70e displays the information of the time meter and the battery voltage until the engine E is started. After the engine E is started, the engine rotation speed is displayed on the main LCD 70e until it is in the working state, and as the working state is reached, the load level and the sieve level information are displayed on the main LCD 70e. Let's do it. Furthermore, the working state is determined by the threshing clutch 37 being connected and the threshing switch S9 is turned on.

In the self-diagnosis mode, as shown in FIG. 23, the information of the self-diagnosis data stored in the memory MEM is decoded and displayed on the main LCD 70e. When the check switch 71 is pressed, the self-diagnosis mode ends.

[Separate embodiment]

Next, another embodiment is described.

In the said 1st-3rd embodiment. Although this invention was applied to the harvesting harvester combine as a working machine, this invention can also be applied to working machines other than a combine. In the working machines other than the combine, normal information, abnormality information (self-diagnosis data), and alarm information are appropriately changed.

In the above first to third embodiments, the plurality of control state display unit 100 and the control switching commander 200 are constituted by dimming switches, special switches and lamps. Instead of such individual switches and lamps, For example, the plurality of control state display unit 100 and the control switching commander 200 may be configured using a display screen of a touch panel display.

In the third embodiment, the display changeover switch 72 is used as the manual operation commander constituting the display commander HS, but other manual switches can be suitably used as the display commander HS.

With the above configuration, even if an abnormality in the operation state occurs during operation of the working machine, the abnormality information regarding the abnormality is not immediately displayed on the image display unit. When the abnormality occurs and the abnormality information is generated, the abnormality It is notified that it occurred. After that, when the operator instructs the display instruction, the abnormality information is displayed on the screen of the display unit in place of the normal information. Therefore, when the abnormality information is generated as in the prior art, the abnormality information is immediately replaced instead of the normal information. Instead of displaying on the screen of the image display unit, even when the operator displays the abnormality information, the abnormality information is displayed when it is judged that there is no problem in operation, and the display of the abnormality information is appropriate without disturbing the operator's operation. Is done. As a result, the operation performed by the operator while viewing the normal information is not hindered by the sudden display switching to the information unless an emergency is required.

Furthermore, in the case of displaying the abnormality information by sentence in regard to the display form of the abnormality information on the image display unit, for example, only the names of sensors or motors in which an abnormality in the operating state is detected are simply displayed, It can be quickly and easily understood.

In addition, when emergency information with high need to notify the operator is generated during operation of the work machine, the emergency information is displayed on the image display unit displaying the normal telegram or the transfer information in preference to the normal information or abnormality information. Therefore, such emergency information can be immediately displayed on the image display unit, so that the operator can take appropriate measures.

In addition, a plurality of control functions are executed to operate the work machine, and the connection cut-off state of the plurality of controls, and thus the operation state and the non-operation state, are selectively displayed on the control state indicator. If an abnormality of either control function occurs, the control state indicator corresponding to the abnormal control function becomes a display state that indicates an abnormality. In addition, the display instruction can be instructed to display abnormal information on the control on the image display unit for confirmation.

According to the present invention, the occurrence of any abnormality of any of a plurality of control functions is notified by the control state display unit, for example, the operator instructs the display command to display the abnormal information on the screen of the display unit, and displays the contents of the abnormal information. After confirming, by operating the control switching commander corresponding to the control function judged to be abnormal, the notification of the abnormality by the control state display unit is stopped and timely returns to the normal display displaying the state of the control function.

In addition, since a display command for abnormal information can be commanded to the controller using a manual operation commander provided for inputting normal operation information to the controller, it is unnecessary to install a dedicated switch or the like as the display commander. As a result, the device configuration can be simplified.
