Description

  The present invention relates to an input device capable of numeric keypad input.

  As shown in FIG. 3, in a work machine such as a hydraulic excavator, an upper swing body 12 is turnable with respect to a lower traveling body 11, and a power source device such as an engine and a hydraulic pump is provided on the upper swing body 12. Since the cab 14 and the work device 15 are mounted together with 13, it is possible to perform various work such as excavation work, crane work, and various attachment work. Such a hydraulic excavator has parameter settings that determine each function and performance, such as the flow rate setting of the attachment used. A monitor 17 having a calculation function is installed in front of the driver's seat 16 of the excavator.

  As a monitor mounted on this type of work machine, for example, a monitor is provided with a numeric keypad together with a liquid crystal screen, and various parameters can be set by inputting from the numeric keypad. Depending on the space occupied by the numeric keypad, There is a problem that the liquid crystal screen becomes relatively small and the overall size is increased (see, for example, Patent Document 1).

  On the other hand, the monitor 17 shown in FIG. 4 is provided with a liquid crystal screen unit 22 and a button operation unit 23 in the monitor main body unit 21, and an up / down key 24 and the like are provided in the button operation unit 23. The button operation unit 23 is closed by a lid cover 26 attached to the lower part of 21 by a hinge 25, and when the button operation unit 23 is operated, it is opened as shown in FIG.

  The normal mode screen 27 is displayed on the liquid crystal screen portion 22 shown on the left side of FIG. 4, and the engine speed and the used attachment flow rate are set on the liquid crystal screen portion 22 shown on the right side of FIG. A service mode screen 28 used for the above is displayed.

  The monitor 17 has the above parameter settings in an area that can be set only by a service person, and specifically includes a configuration mode and tool programming. The service mode screen 28 shown on the right side of FIG. 4 is an example of a service mode configuration screen.

  In the current aircraft, when various parameters are set on the monitor 17, the up / down key 24 is used to change the numerical value of the parameter.

JP 2003-97338 A (page 3, FIG. 2)

  When changing the numerical value using the up / down key 24 like this, the target numerical value cannot be directly input. For example, even if trying to input 1980 rpm, the numerical value must be increased or decreased from the previous value. It takes time and workability is not good.

  As shown in FIG. 1, a monitor 17 installed in a cab 14 of a hydraulic excavator, an airframe controller 18 that electronically controls hydraulic equipment such as a traveling system, a turning system, and a work device 15 of the hydraulic excavator, and an in-vehicle engine An engine controller 19 that electronically controls the fuel injection and a switch panel module 29 are connected by a controller area network bus (CAN bus) 30. The switch panel module 29 is installed on a console 16c integrated with the driver's seat 16 in the cab 14 in FIG.

  The monitor 17 has a calculation storage function, and operates a home button switch 23h, a menu button switch 23m, an OK button switch 23ok, a cancel button switch 23c, and the like shown in FIG. 4, and a normal mode screen shown on the left side of FIG. 27 can be switched to the service mode screen 28 shown on the right side of FIG. 4. In this service mode screen 28, the numerical value is changed by the up / down key 24 for increasing / decreasing the numerical value to set and use the engine speed. It is originally equipped with a numeric input function that can set the attachment flow rate.

  Further, the switch panel module 29 connected to the monitor 17 has a plurality of buttons used as input keys of the monitor 17 to which any of numerals, letters (alphabet, kana, etc.) and symbols are assigned when the monitor 17 is in the input mode. Switches 31-40 are provided.

  As shown in FIG. 1, these button switches 31 to 40 are used as numeric keys when the monitor 17 is in a numeric input mode. These button switches 31 to 40 include at least 1 to 9 and A numeric value of 0 is assigned, and an assigned numeric value input function for inputting these numeric values to the monitor 17 is provided. However, considering the assignment of characters or symbols by switching the input mode, the switch panel module 29 has 10 types. You may install more button switches. In short, according to the input mode, any one of numbers, letters, and symbols is appropriately selected.

  Illustrating the original functions of the illustrated button switches 31 to 40, the button switch 31 is, for example, a switch that switches to an eco mode that suppresses the engine speed, and the button switch 32 is, for example, a switch that switches the running speed slowly or suddenly. Yes, the button switch 33 is a switch that switches to an auto-decel mode that automatically reduces the engine speed when there is no load, for example, the button switch 34 is a switch that releases an alarm sound during driving, for example, and the button switch 35 For example, a switch for switching the bucket attachment mode, the button switch 36 is a switch for turning on / off a rear view camera, for example, the button switch 37 is a switch for turning on / off a light, for example, and the button switch 38 is For example, a switch that turns the wiper on cab 14 on and off The button switch 39 is, for example, a switch for turning on / off a wiper cleaning liquid pump, and the button switch 40 is, for example, a switch for switching to a crane mode.

  Further, the switch panel module 29 includes an accelerator dial 41 for setting the engine speed when there is no load, and the accelerator dial 41 sets the engine speed with a dial scale 42 of at least 10 steps. At this time, an assigned numerical value input function is provided for inputting, to the monitor 17, numerical values assigned to at least the 10 dial scales 42 of the accelerator dial 41.

  In conjunction with the accelerator dial 41, the numerical value 43 on the monitor screen can be changed or selected on the monitor screen according to the numerical value assigned to the dial scale 42 on the service mode screen 28 shown on the right side of FIG. It also has a function to slide the item 44 to be performed.

  The input mode of numbers, characters and symbols may be switched on the monitor 17 side or on the switch panel module 29 side. For example, the input mode is switched on the selection screen displayed by the menu button switch 23m on the monitor 17 side, or the input mode is switched by the accelerator dial 41 when the button switches 31 to 40 on the switch panel module 29 are used as input keys. Alternatively, switches for switching the input mode (not shown in FIG. 1) may be installed on the switch panel module 29.

  Next, the function and effect of the embodiment shown in FIG. 1 will be described with reference to the flowchart in the case of the numeric input mode shown in FIG.

(Step 1)
It is determined whether or not the monitor 17 is in the normal operation mode.

(Step 2)
In the normal operation mode, the normal mode screen 27 displays basic information such as the time, the accelerator dial position, the fuel level, the hydraulic oil temperature, the coolant temperature, and the operation time shown on the left side of FIG.

(Step 3)
When the monitor 17 is in the normal mode screen 27, when the button switches 31 to 40 of the switch panel module 29 are pressed, switching of various functions inherent to the button switches 31 to 40 can be selected.

(Step 4)
When the accelerator dial 41 is operated while the monitor 17 is in the normal mode screen 27, the engine speed when there is no load can be selected as a numerical value set on the dial scale 42 indicated by the accelerator dial 41.

  Thus, when the monitor 17 is in the normal operation mode, the switch panel module 29 operates as a normal switch and an accelerator dial.

(Step 5)
When the monitor 17 is not in the normal operation mode, the service mode screen 28 is displayed.

(Step 6)
On the service mode screen 28, a numeric input mode is set.

(Step 7)
When the monitor 17 enters the numerical value input mode of the service mode screen 28, it is out of the normal operation mode, and 1-9 and 0 are assigned to the button switches 31-40 of the switch panel module 29. ˜40 functions as a numeric keypad for inputting 1 to 9 and 0.

  Further, the value of the accelerator dial 41 of the switch panel module 29 can be changed greatly. For example, in the range of 0 to 4000 kPa, the dial scale 42 of the accelerator dial 41 is 1 to 10, so that “400” is 1 scale. The automatic allocation function that increases in increments works, and “1” on the dial scale 42 is assigned to 0, “2” on the dial scale 42 is assigned to 400, “3” is assigned to 800, “4” is assigned to 1200 in order. Can do.

  Further, when the monitor 17 is switched to the character or symbol input mode, the characters or symbols assigned thereto are input to the monitor 17 from the button switches 31 to 40 of the switch panel module 29 connected to the monitor 17. .

  In this way, the switch panel module 29 connected to the monitor 17 includes a plurality of button switches 31 to 40, and when the monitor 17 is in the input mode, these button switches 31 to 40 are either numbers, letters or symbols. Since it is used as an input key for the assigned monitor 17, it is possible to efficiently input any number, letters, or symbols from the switch panel module 29 located outside the monitor to the monitor 17 to the monitor 17. The workability of input work can be improved.

  In particular, the switch panel module 29 connected to the monitor 17 via the CAN bus 30 includes at least ten types of button switches 31 to 40 used as numeric keys. When the monitor 17 is in a numeric input mode, these button switches 31 to Since the assigned numerical value input function to input the numerical value assigned to 40 to the monitor 17 is provided, the button switches 31 to 40 used as these numeric keys allow efficient numeric key input to the monitor 17 that does not have a numeric keypad. This makes it possible to improve the workability of numerical input work.

  In addition, since the numeric dial input mode has an assigned numeric value input function for inputting the numeric value assigned to the dial scale 42 of at least 10 steps of the accelerator dial 41 provided in the switch panel module 29 to the monitor 17, this accelerator dial 41 is provided. Thus, an efficient numerical value input operation can be performed on the monitor 17.

  Furthermore, as another function, by making the dial scale 42 of the accelerator dial 41 correspond to a plurality of items on the monitor display screen, the item selection by the accelerator dial 41 can be simplified.

  In this way, the serviceability of the monitor 17 can be improved, but furthermore, by assigning numerical values to the button switches 31 to 40 of the switch panel module 29, it becomes possible to support password input without a monitor screen, A work machine anti-theft function can be easily added.

  The input device of the present invention can be used in the manufacturing industry of work machines.
