Thus, the sensor check mode is displayed (details will be described later), and the cursor up / down movement switches 16a and 16b are used to move the screen up and down.

  FIG. 3 is a system configuration diagram of the sensor check / monitor display device. The monitor controller 21, which is a control unit of the monitor display device, receives the mode selection signal of the sensor adjustment switch 15 and the switching auxiliary signal by the switching auxiliary switch 14b, and receives information on the device operating state from the device controller 22 with a sensor check function. The sensor check information is received in a switchable manner, and the combine device operating state information and the sensor check information are switched and controlled by a control process according to the conditions. The monitor display processing unit 23 is provided to control the display of the monitor display unit 12.

  The monitor controller 21 is provided with a controller communication unit 21c connected to the monitor display processing unit 23, and by a predetermined operation of the sensor adjustment switch 15 received via the timer count processing unit 24t for timing and the digital signal input processing unit 21a. A sensor check mode selection unit 24c for instructing the monitor display processing unit 23 to switch the output mode by a mode selection signal is provided.

  The controller communication means 21c receives information on the operating state of the device from the device controller 22 when displaying the device monitor information. When displaying the sensor check information, the controller communication means 21c receives a switching signal from the sensor check mode selection unit 24c. Transmission from the device controller 22 is switched via the communication means 21c.

  The timer count processing unit 24t performs a count process of a long press operation (for example, 1 second or more) of the sensor adjustment switch 15. Based on this count process, the sensor check mode selection unit 24c makes a switching determination. By this switching determination, a conventional switch can be shared without requiring a special dedicated switch.

  The device controller 22 is provided with a sensor check means 22s and a monitor communication means 22c in addition to receiving the switch and sensor input signals for device operation control and driving the device according to the conditions, and outputs a horn to the sensor check means 22s.

The sensor check unit 22s performs a sensor check on the device control switch and the sensor input signal based on the signal from the monitor communication unit 22c, and sends the sensor check information to the monitor communication unit 22c.
The monitor communication unit 22 c transmits device operation information or sensor check information from the device controller 22 to the monitor controller 21 in accordance with a switching signal received from the monitor controller 21.

  In the normal case, the monitor display device for sensor check having the above-described configuration is such that the traveling speed is 0.9 m / s and the storage capacity of the Glen tank is full as in the monitor display example of FIG. Device operation information such as 3/5 is displayed on the monitor display unit 12.

  By performing an operation with a predetermined weighting condition such as a long press operation of the sensor adjustment switch 15, the sensor check mode is switched to the sensor check mode and the sensor check means 22 s of the device controller 22 is activated. ), The sensor check information of each item of the power steering lever, power steering position, spin turn switch, and mild turn switch is displayed.

  In the display example of FIG. 4B, the item of the power steering lever indicates the left tilt detection by reversing the left / right tilt situation. The power steering position item indicates a tilt position of “3.2v” for a lever tilt situation within a range where the rightmost tilt position is “0v”, the neutral position is “2.5v”, and the leftmost tilt position is “5v”. In the items of the spin turn switch and the mild turn switch, the detection of “off” is indicated by inversion for each on / off status. If the operation status of these levers and switches is different from the display, it can be recognized as an abnormality.

  Further, by switching the screen items, each of the items of the auger automatic storage switch, the auger automatic extension switch, and the auger automatic stop switch is displayed on the monitor display unit 12 as in the auger-related display example of FIG. Displays sensor check information.

  In the display example of FIG. 4C, the on / off states of the auger automatic storage switch, auger automatic extension switch, and auger automatic stop switch are shown by inversion. If the operation status of these switches is different from the display, it can be recognized as an abnormality.

  For sensor check information in such sensor check mode, unless the operator performs an operation with a predetermined weighting condition for mode switching, the device operation information necessary for the work is displayed on the monitor display unit 12 in accordance with the operator's intention. It is always displayed, and the operator can efficiently proceed with the cutting operation based on the device operation information. In addition, if necessary when the vehicle travels or the work equipment breaks down, check information is displayed on the monitor display unit 12 by an operation with a predetermined weighting condition, and failure diagnosis can be performed based on the check information. Adjustment of the sensitivity range of the sensor can be optimized in the same manner.

Next, the above-described operation with a weighting condition will be described.
The operation with a predetermined weighting condition for switching to the sensor check mode is a reliable management environment without providing a special dedicated switch as in the example of operating any of the switches provided for monitoring operation for a predetermined time or more. It is an object of the present invention to prevent an inadvertent switching due to sharing of an existing switch by obtaining a clear intention display of an operator necessary for a sensor check that requires.

  Therefore, in addition to the above, in another example, it is a condition that any two of the switches provided for monitor operation are operated for a predetermined time or more, and in another example, provided for monitor operation. Any one of the switch operation signals is transmitted to the device controller 22, and the sensor check mode is switched on condition that a predetermined switch is operated on the controller 22 side during the reception.

On the other hand, when it is determined that the combine is in operation, for example, when “threshing-in”, “grain sensor on”, and “vehicle speed (speed sensor value) higher than a predetermined value” are detected simultaneously from the device controller 22, Even if a conditional operation is performed, it is possible to prevent erroneous operation during work by checking the switch to the sensor check mode.
Also, when the auger is in the overhanging position, the discharge switch is operated, and the engine speed (engine speed sensor value) is equal to or higher than a predetermined value, the switching to the sensor check mode is restrained as described above. Thus, it is possible to prevent erroneous operation during work.

  Next, regarding the end condition of the sensor check mode, after switching to the sensor check mode by the operation with the above-mentioned weighting condition, “threshing-in”, “grain sensor on”, and “vehicle speed higher than predetermined” are simultaneously detected from the device controller 22 When this is done, the sensor check mode is terminated and switched to the normal mode, so that erroneous operations during work can be prevented.

  Also, when the auger is in the overhanging position, the discharge switch is operated, and the engine speed (engine speed sensor value) is equal to or higher than the predetermined value, the sensor check mode is terminated and the normal mode is set as described above. By switching to, erroneous operation during work can be prevented.
