Hereinafter, substantially identical components in the description and the accompanying drawings are denoted by the same reference numerals, respectively, and redundant description will be omitted. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In the meantime, the term "and / or" as used in the present invention includes any combination of a plurality of related listed items or any of a plurality of related listed yields.

The technical term "display device " used in the present invention is a generic term collectively referred to as an apparatus for providing an analog or digital display device, and may be abbreviated as" display "or" monitor "or" instrument panel ". Further, the "display device" of the present invention may be an apparatus composed of one or more monitors or a dash panel. Furthermore, the "display device" of the present invention may be an integrated or independently configured device with a control (or processor) that operates a "display ".

The technical term "joystick " used in the present invention is a device for operating a construction machine mounted on an operator's chair. The "joystick" of the present invention may be configured as a pair of left and right, or may be configured on the left or right side of the operator's chair. Meanwhile, as an embodiment of the present invention, the "joystick" of the present invention is an operation device capable of remotely operating a boom, an arm, and a bucket of a construction machine, (Or a switch, a function key or a control key). Alternatively, as an embodiment of the present invention, the "joystick" of the present invention may map hotkeys (or HOT Keys) that can manipulate the display device to buttons that are already configured.

The technical term "construction machine" used in the present invention is not limited to literally machines used for construction but is a generic meaning of all the vehicles to which the joystick and display device according to the present invention are applied.

The basic concept of the present invention is as follows: 1) Further configuring buttons (or control keys or function keys) capable of operating a display device on a joystick for operating a construction machine; 2) providing a mode of operation of the joystick for a work operation mode for operation of a construction machine and a dashboard operation mode for remotely operating a display device; 3) mapping each function capable of operating the display device to each button (i.e., function keys) configured in the joystick.

3 is a view illustrating a joystick of a construction machine according to an embodiment of the present invention.

3 is an example in which a pair of joysticks 31 and 32 are formed on the chair 30 of the operator. FIG. 3 shows an embodiment in which four physical keys are configured in the right joystick 31 among the pair of joysticks 31 and 32. FIG.

As shown in FIG. 3, the joystick 31 is an embodiment constituting four function keys 31-1, 31-2, 31-3 and 31-4. On the other hand, for example, the four function key types may be push switches or other types of switches.

FIG. 4 is a table showing an operation mapped to the function keys configured in the joystick of FIG. 3 according to an embodiment of the present invention.

The joystick 31 according to the present invention can provide the "operation mode for work" and the "instrument panel operation mode ". For example, when a specific function key (for example, the function key 31-2) is pressed for a predetermined time (for example, set to N seconds), the operation mode is switched from the "operation mode for work" to the "instrument panel operation mode" . On the other hand, the "instrument panel operation mode" can be divided into "basic instrument panel operation mode" and "instrument panel HOT key mapping operation mode". For example, when a specific function key (for example, the function key 31-2) is pressed for a predetermined time (for example, set to N + 1 seconds), the "instrument panel HOT Key mapping operation mode" Can be switched. That is, it can be toggled into three modes, namely, the "operation mode for work", the "basic instrument panel operation mode" and the "instrument panel HOT key mapping operation mode" according to the pressing time of the specific function key.

This will be described below with reference to Figs. 3 and 4. Fig.

As shown in Fig. 4, the four function keys can be used for an operation of a construction machine which is a current system. For example, "function key 1 31-1" is applied to "boost / breaker" operation; Function key 3 (31-3) "is applied to" TWO WAY OPEN "and" function key 4 (31-4) "is applied to" In other words, the function of the joystick is to perform a specific operation for the operation of the construction machine, that is, the operator can operate the joystick and the function keys in the "TWO WAY CLOSED" The boom, the arm and the bucket of the construction machine can be operated by using the boom, arm and bucket of the construction machine.

Meanwhile, according to the present invention, the four function keys 31-1 to 31-4 can be mapped to functions for operating the instrument panel. In addition, the four function keys can be classified into "basic instrument panel operation mode" and "instrument panel HOT key mapping operation mode". For example, as shown in [Table 1] of FIG. 4, four function keys can be applied to the functions of the " basic instrument panel operation mode ". That is, "function key 1 (31-1)" is applied to "ENTER "; "Function key 2 (31-2) is applied to" ESC ";" Function key 3 (31-3) "is applied to" UP ";" Function key 4 Can be applied.

 For example, the operator can operate the currently operated construction machine as a "step-up or breaker" by using the "function key 1 (31-1)" in the currently set "work operation mode". At this time, the operator can switch the mode to the "basic instrument panel operation mode" in which the instrument panel can be operated by pressing the function key 2 (31-2) for a predetermined time (for example, 2 seconds to 3 seconds). When the current system, the construction machine, switches to the "basic instrument panel operation mode", the operator can press the "function key 1 (31-1)" corresponding to the "ENTER" function have. Also, for example, when the operator wants to get out of the page currently displayed on the instrument panel, he / she can press the "function key 2 (31-2)" corresponding to the "ESC" function. Further, when the operator presses the page currently displayed on the instrument panel by pressing the function key 3 (31-3) and / or the function key 4 (31-4) corresponding to "UP" and / or "DOWM" The user can move the page displayed on the screen. Therefore, the operator can operate the instrument panel simultaneously with the ongoing work (that is, the operation of operating the joystick of the construction machine) at the same time, without leaving the operating hand in the joystick to operate the instrument panel.

On the other hand, the four function keys 31-1 to 31-4 of the joystick 31 can be used by switching to the "instrument panel HOT Key mapping operation mode" in the "instrument panel operation mode". For example, when the user presses the "function key 2 (31-2)" for a predetermined time (for example, 3 to 4 seconds), the four function keys of the joystick 31 are set to the " Can be set to be switched. At this time, the four function keys of the joystick 31 can set a function desired by the operator. For example, the operator is a hot key for operating the instrument panel, the "function key 1 (31-1)" is applied to the "Power Mode" "Function key 2 (31-2) is applied to" Work Mode ";" Function key 3 (31-3) "is applied to" Auto Idle ";" Function key 4 Quot; hot key mapping operation mode "described above may be applied to the function keys (not shown) of another joystick 32 without being implemented in the joystick 31 as another embodiment. .

5 is a flowchart illustrating a method of operating a dashboard with a joystick of a construction machine according to an embodiment of the present invention.

Hereinafter, a description will be given with reference to Figs. 3 to 5. Fig.

The operator operates the joystick 31 to operate the construction machine, which is the current system, to carry out the work. At this time, the function keys 31-1 to 31-4 of the joystick can be input in a state where the operator is set to the "operation mode for work ". When a signal is input from the function keys 31-1 to 31-4 of the joystick 31, a vehicle control unit (VCU) (or a control unit) receives the signal and changes the mode of the joystick 31 It is determined whether the signal is a request signal (S52). Particularly, in order for the operator to operate the function key 2 (31-2) of the joystick 31 for a predetermined time (for example, 2 seconds to 3 seconds corresponding to the "basic dashboard mode" or " (3 seconds to 4 seconds corresponding to the " mapping operation mode "), the vehicle controller first determines whether the signal from the joystick function key 2 (31-2) is the" basic dashboard mode " For example, if the operator depresses the function key 31-2 of the joystick 31 for a predetermined time (for example, 2 seconds to 3 seconds), the vehicle controller requests it to switch to the " It is determined that the function keys 31-1 to 31-4 of the joystick 31 are corresponding to the respective function keys (i.e., "ENTER "," "ESC", "UP" and "DOWN") (S54). On the other hand, for example, if the operator presses the function key 2 (31-2) of the joystick 31 for a predetermined time (for example, 3 seconds to 4 seconds) (S55), and the function keys 31-1 to 31-4 of the joystick 31 are set to be the same as those shown in Fig. 4 (I.e., "Power Mode", "Work Mode", "Auto Idle", and "Camera Mode") in which the instrument panel can be operated (S56).

On the other hand, if the signal from the function keys 31-1 to 31-4 of the joystick 31 is not the signal of the function key 31-2 in the step S52, the vehicle controller is operated in the "operation mode for work" (E.g., a boom, an arm, or a bucket) so as to perform a function corresponding to the input of the corresponding function key (S57).

6 is a block diagram of an apparatus for operating a dashboard with a joystick of a construction machine according to an embodiment of the present invention.

As shown in FIG. 6, only components of the construction machine 60 that operate the instrument panel are schematically shown. 6 shows a joystick 61, a vehicle controller 62, a mechanical part 63, and a dashboard (or display) 64. In this regard, Thus, a construction machine 60 embodying an embodiment of the present invention includes all of the other physical components for performing the operations and functions of the present invention.

6, the joystick 61 may be used to remotely operate a mechanical part (e.g., a boom, a female, or a bucket) to physically operate the mechanical part 63 of the construction machine 60 Adjustment device. In particular, the joystick 61 may be configured as a pair or a joystick as shown in Fig. 3, the joystick 61 may further comprise at least one or more function key sets 61-1 to 61-4, and each of the function keys is connected to the instrument panel 64 as described above, To the function keys 61-1 to 61-4.

The vehicle controller (VCU) 62 monitors the operation signals from the joystick 61 and signals from the function keys 61-1 to 61-4 (i.e., 31-1 to 31-4 in Fig. 3) of the joystick 61 do. When a signal is received from the joystick 61, the vehicle controller 62 first determines whether the signal is a signal requesting the mode switching of the joystick. If the signal is determined to be a signal requesting the mode switching of the joystick (first judgment for convenience), the vehicle controller 62 again determines whether the signal is the " basic instrument panel operation mode "or the " instrument panel HOT key mapping operation mode" (Second judgment for convenience). Meanwhile, the manner in which the vehicle controller 62 determines the respective modes is the same as that described with reference to FIGS. The vehicle controller 62 receives a signal of a specific function for operating the instrument panel 64 in the " basic instrument panel operation mode "or the " instrument panel HOT key mapping operation mode" So that the function corresponding to the signal is performed through the instrument panel 64. [ That is, the vehicle controller 62 converts an analog signal transmitted from the function keys 61-1 to 61-4 of the joystick 61 into a CAN signal, which is a digital signal, so that an operation corresponding to the function key is operated from the instrument panel So as to control the instrument panel. On the other hand, the vehicle controller 62 checks which mode the current system is in, and controls the instrument panel to display the current system mode on the instrument panel with an icon or the like. For example, as shown in FIG. 7, the vehicle controller 62 may display a "joystick" icon on the instrument panel 64 to indicate that the current system is the "instrument panel operation mode". In addition, the vehicle controller 62 controls the instrument panel to display a notification, for example, a notification pop-up window, on the instrument panel 64 when a mode change occurs in the current system mode, as shown in FIG.

FIG. 8 is an example of an operation of processing an instrument panel operation signal input by a joystick of a construction machine according to an embodiment of the present invention. The joystick 61 corresponds to the joystick 31 of Fig. 3 and the function keys 61-1 to 61-4 of the joystick 61 correspond to the corresponding functions of the joystick 31 of Fig. Keys 31-1 to 31-4, respectively.

FIG. 8 is a simplified illustration of an embodiment of the present invention described with reference to FIGS. That is, when the operator requests a signal for operating the instrument panel by using the function keys 61-1 to 61-4 of the joystick 61, the vehicle controller 62 switches the signal to the CAN signal to operate the instrument panel 64 do. For example, assuming that the present system is in the "instrument panel operation mode", when the operator presses a function key (for example, 31-3 in FIG. 3) for which the "UP" function is set among the function keys of the joystick 61 , The vehicle controller 62 receives the signal of the function key (i.e., 31-3 in Fig. 3) and switches to the corresponding CAN signal that can control the instrument panel 64 and also displays the current page To move up.
