DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for displaying, for example, a vehicle speed for performing a harvesting operation for continuously cutting and threshing a grain stalk.

[0002]

Conventionally, a display is provided on the operation unit to display the operation status. However, in a structure in which the display is provided for each display content, the display mechanism is complicated and the cost tends to be high. In addition, with the structure where the contents that need to be displayed temporarily are displayed continuously in the same way as the contents that need to be displayed continuously, the compactness of the display and the improvement of the display function etc. There is a problem that it cannot be easily achieved.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention relates to a combine having a threshing unit, a reaping unit, a driver's seat, and a general display for displaying a harvesting operation state in a driving operation unit. Alternatively, a display section of the load or the vehicle speed is provided on the monitor surface of the general display, so that the display mechanism can be simplified and downsized more easily than before, and the manufacturing cost can be reduced and the display function can be easily improved. It is possible to achieve.

When the display (35k) of the error code (5g) is turned on and the buzzer stop switch (48) is continuously turned on for a certain period of time (for example, 5 seconds) during this display, the display is switched to the vehicle speed and the error display is displayed. Done.

The error display is made by the controller (49) (5).
0) is performed in the order of the number and the error code, and when a plurality of errors occur, the display of the error code is switched every predetermined time (for example, 2 seconds), and when all the error codes are displayed, the display returns to the vehicle speed display. .

FIG. 8 shows an example of reading out error information generated in each of the controllers (49) and (50). The liquid crystal display (36) periodically (for example, every one second) sends the information to the controllers (49) and (50). 1) sends a 6-byte error read command.

An error read command from the display (36) is: an error read command ('E''R'')
R '), ID number (01H), End command ('
E′′N ″ D ′), and transmits a command to the controller (49) (50) as ID number = 1.

The controller (49) (50) receives the error read command, and adds 1 to the ID number (02) when the first controller (49) has no error information.
H) An error read command is transferred to the second controller (50), and if there is error information in the second controller (50), an error read command ('E''R'')
R ′), the ID number (03H) of the controller (50) is transmitted, and finally the end command (“E”)
'N''D') is transmitted to the display (36).

Further, when there is error information in the first controller (49), an error read command (`E`
'R''R') followed by its own ID number (02
H) and error codes (23H, 24H, 25H, 34)
H, 35H) (5 errors have occurred in the first controller (49)), and finally the end command ('E'')
N '' D '), and if there is error information in the second controller (50), an error read command ('
E '' R '' R '), the error code of the first controller (49) before being received is transmitted as it is,
Next, the error code (23H, 24H) generated in the second controller (50) (two errors have occurred in the second controller (50)) is similarly transmitted, and finally the end command is transmitted to the liquid crystal display (36). Send.

The command sent from the liquid crystal display (36) to each of the controllers (49) and (50) is fetched when error information is present in each of the controllers (49) and (50). Returning to the liquid crystal display (36), the ID numbers (C1) and (C2) of the controllers (49) and (50) and their error codes (23H etc.) are sequentially displayed on the monitor display (35g) as shown in FIG. Is what you do.
