A vehicle speed sensor (46) to be displayed, a display changeover switch (47) for switching display on the monitor display section (35g) and a buzzer stop switch (48) as a changeover switch are input to the liquid crystal display (36). Connected.
[0010]
Then, a first controller (49 that performs the cutting height control of the cutting unit (8), the handling depth control of the culm, the horizontal control of the vehicle body, the threshing control for keeping the threshing load constant, the vehicle speed control, etc. in the combine work) ) And a second electronic governor controller (50) for controlling the electronic governor of the engine (21). The liquid crystal display (36) and the controllers (49) (50) are connected to the communication line (51). Are connected to the loop, and the rotational speed and rotational load of the engine (21) are displayed on the monitor display sections (35h) and (35i).
[0011]
Furthermore, a photoelectric display element (52) that displays the charge state of the battery on the monitor display unit (35j) by light emission, and a hydraulic display element (53) that displays the appropriateness of the oil supply pressure of the engine oil on the monitor display unit (35j). A water temperature display element (54) for displaying the coolant temperature of the engine coolant on the monitor display section (35j) and a heater display element (55) for displaying the heater heating temperature on the monitor display section (35j). Provided in the vessel (34).
[0012]
In the monitor display section (35g) for displaying the vehicle speed, when an error occurs in each controller (49) (50) and the buzzer stop switch (48) is operated, the controller (49) is replaced with the vehicle speed display. The error (50) is configured to be displayed.
[0013]
The operation will be described below with reference to the flowchart of FIG. 6 and the flow of FIG. 7. When the vehicle speed is always displayed on the display unit (35g) and an error occurs in each controller (49) (50). When the error code display (35k) on the display unit (35g) is lit, and the buzzer stop switch (48) is turned on continuously for a certain time (for example, 5 seconds) during this display, the vehicle speed is switched. Error is displayed.
[0014]
Error display is performed in the order of the controller (49) (50) number and error code. When multiple errors occur, the error code display is switched every predetermined time (for example, 2 seconds), and all error codes are displayed. Then, the display returns to the vehicle speed display.
[0015]
FIG. 8 shows an example in which error information generated in each controller (49) (50) is read. The controller (49) (50) is periodically (for example, once a second) from the liquid crystal display (36). A 6-byte error read command is sent to.
[0016]
Error reading commands from the display (36) are: (1) error reading command ('E''R''R'), (2) ID number (01H), (3) end command ('E''N) ”D”), and the command is transmitted to the controller (49) (50) with ID number = 1.
[0017]
Also, the controller (49) (50) receives the error read command. If there is no error information in the first controller (49), 1 is added to the ID number (02H) and the error read command is sent to the second controller (50). When there is error information in the second controller (50), the error read command ('E''R''R') is followed by the ID number (03H) of this controller (50), Finally, an end command ('E''N''D') is transmitted to the display (36).
[0018]
Further, when there is error information in the first controller (49), the error read command ('E''R''R') is followed by its own ID number (02H) and error code (23H, 24H). , 25H, 34H, 35H) (five errors have occurred in the first controller (49)), and finally the end command ('E''N''D') is transmitted to the second controller (50). If there is error information, the error code of the first controller (49) before reception is transmitted as it is after the error read command ('E''R''R'), and then the second controller ( The error code (23H, 24H) generated in (50) (two errors are generated in the second controller (50)) is similarly transmitted, and finally the end command is transmitted to the liquid crystal display (36).
[0019]
Thus, the command sent from the liquid crystal display (36) to each controller (49) (50), when there is error information in each controller (49) (50), takes this information into the liquid crystal display. Returning to the device (36), the ID number (C1) (C2) of the controller (49) (50) and its error code (23H, etc.) are sequentially displayed on the monitor display (35g) as shown in FIG. is there.
[0020]
【The invention's effect】
As is apparent from the above embodiments, the present invention includes the controllers (49) and (50), and detects the operation of the mobile farm machine in the general display device of the mobile farm machine controlled by the controller (49) and (50). The display (35) which displays the information of the sensors (37) to (46) and the controllers (49) and (50) to be displayed on the same display surface is provided, and the controllers (49) and (50) are provided on the display (35). Error code display (error reporting means) (35k) that indicates that an error has occurred when an error occurs, the location where the error occurred (controller number) and error information only when an error occurs A display unit (error content display means) (35g) for displaying and a buzzer stop switch (content display switch) (48) for displaying the display unit (35g) are provided. Since not more, it can be turned and functional information readily ascertainable, such as multiple devices to equip the vehicle body in a single display, to improve the workability and economic efficiency. Further, it is possible to easily and accurately confirm error information of the controller when necessary.
[0021]
Further, since the error information read signal is output from the display unit (34) to the plurality of controllers (49) and (50) at regular intervals, the error information of all the controllers (49) and (50) is displayed when necessary. There are remarkable effects such as easy and accurate confirmation. In addition, when a plurality of errors occur, a plurality of error information is sequentially displayed on the display unit (error content display means) 35g at regular intervals, so that the error information of all the controllers (49) and (50) can be easily and accurately displayed.
