This operation will be described below with reference to the flow chart of FIG. 6 and the display operation explanatory diagram of FIG. 7. The display unit (35g) always displays the vehicle speed, and the controllers (49) and (50) display the vehicle speed. When an error occurs, the error code display (35k) on the display unit (35g) is turned on, and the buzzer stop switch (48) is continuously turned on for a certain time (for example, 5 seconds) during this display. At this time, the vehicle speed is switched to display an error.

The error display indicates 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 controller (49) (50). The controller (49) (50) is periodically (for example, 1 second) from the liquid crystal display (36). Send a 6-byte error read command once).

The error read command from the display (36) is the 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.

Further, the controllers (49) and (50) receive the error read command, and if the first controller (49) has no error information, add 1 to the ID number (02
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 the first controller (49) has error information, 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 controller (49) (50) in this way takes in this information when each controller (49) (50) has error information. Returning to the liquid crystal display (36), the ID numbers (C1) (C2) of the controllers (49) (50) and their error codes (23H etc.) are sequentially displayed on the monitor display (35g) as shown in FIG. To do.

Further, as shown in FIG. 9, in the monitor display section (35g), both the display changeover switch (47) and the buzzer stop switch (48) are turned on, and this on state continues for a predetermined time (for example, 5 seconds). When the display is in the initial setting mode, the display (35g) displays the initial setting mode (35
m) is turned on, and the numerical value (1 in this case) of the initial setting mode corresponding to various controls is blinkingly displayed on the display unit (35g). For example, the first controller (4
In 9), 1; cutting height control, 2; handling depth control,
3; vehicle body horizontal control, 4; threshing control, 5; vehicle speed control.

Then, as also shown in FIG. 10, every time the display changeover switch (47) is turned on, 2, 3, 4, 5 are turned on.
When the buzzer stop switch (48) is turned on during the blinking display, the mode is determined and the numerical value is displayed continuously (lighted).

Further, as shown in FIG. 11, when the mode is decided, for example, the following transmission / reception is performed between the display (36) and the controller (49).

An initialization code corresponding to the mode is transmitted to the controller (49) (50). (FIG. 11 is for horizontal body control) 1; Mowing height control "INKS"2; Depth control "INDS"3; Horizontal body control "INUS"4; Threshing control "INTS"5; Vehicle speed control "INSS"

In this case, the initial setting code is the indicator (3
For example, a reference value to be written or a detection value at that time of a tilt sensor for detecting a tilt of a vehicle body is fetched and transmitted to the controller (49).

Then, when the initialization code related to the controller is sent, the controller enters the initialization mode, and the reference value of the control written on the display (36) and the inclination for detecting the inclination of the vehicle body are detected. Initial setting is performed by reading sensor values of various controls at that time such as sensors as set values, and a response code ending in “M” is transmitted to the display (36). 1: harvesting height control "INKM" 2: handling depth control "INDM" 3: body level control "INUM" 4: threshing control "INTM"5; vehicle speed control "INSM"

The irrelevant initialization code is directly transmitted to the second controller (50), and the second controller (50) transmits the received initialization code to the display (36) as it is.

When the display device (36) receives the response code, the display of the initial setting mode (35 m) and the numerical value (3 in the case of the embodiment) of the mode corresponding to the received response code are displayed for a fixed time (for example, 2 seconds). indicate. (If nothing is received for a predetermined time (for example, 2 seconds) after transmitting the initial setting mode, the mode returns to the normal mode.)

When all the initial settings are completed by the controllers (49) (50), the initial setting completion code ending with “F” is transmitted to the display (36). 1: harvesting height control "INKF" 2: handling depth control "INDF" 3: body level control "INUF" 4: threshing control "INTF"5; vehicle speed control "INSF"

The irrelevant initialization code is transmitted to the next second controller (50) as it is, and the second controller (50) transmits the received initialization completion code to the display (36) as it is.

When the display device (36) receives the initial setting completion code, it sounds the buzzer (56) for a fixed time (for example, one second), ends the initial setting mode, and returns to the normal vehicle speed display. (If nothing is received for a predetermined time (for example, 2 seconds) after transmitting the initial setting mode, the mode returns to the normal mode from the initial setting mode.)

Then, by sending an initialization code from the display (36) to each controller (49) (50) to enable the initialization of the controller (49) (50), each controller (49) ( 50) It is possible to eliminate the need for input / output for each initial setting, and to write the initial setting command code in the rewritable memory of the display unit (36) even if the model and specifications are different, ) Can be made to correspond to this without changing the program.
