Description

[Technical Field]

[0001] The present invention relates to a system for inputting information into a work machine such as a hydraulic excavator. [Background technology]

[0002] BACKGROUND ART In recent years, work machines such as hydraulic excavators have become increasingly multifunctional, and a large number of electronic devices are being installed in the work machines.

[0003] One function realized by these electronic devices is machine guidance (MG), which calculates the position and posture of the work machine and its working equipment from information acquired by various sensors attached to the work machine and its working equipment, and assists the operator in the work by notifying them of their positional relationship with the target surface during construction.

[0004] There is also an area restriction function that assists in working within the work area by calculating the degree to which the work machine and work equipment are approaching the boundary of the work area from information on the position and posture of the work machine and work equipment and information on the pre-set work area, and notifying the operator and imposing operational restrictions on the work machine or work equipment according to the degree of proximity.

[0005] Furthermore, there is a function to notify the operator of the situation around the work machine using image information etc. based on information obtained from sensors such as cameras mounted on the work machine, and a function to detect nearby workers and notify them of the detected information.

[0006] In order to use the various functions mentioned above, an input device is required that can input information for setting each function, etc. Examples of such input devices include lever switches provided on control levers that operate various actuators. Recently, various information devices such as touch panel monitors have also come to be used as input devices in work machines.

[0007] As the functionality of work machines increases, the number of input devices installed on work machines also increases, resulting in a vast number of combinations of functions and input devices. The more appropriate the combination of functions and input devices, the more efficient the work.

[0008] In the excavator of Patent Document 1, one of a plurality of functions can be selectively assigned to an operation switch (input device) provided on the operation lever, so that the operator can improve work efficiency by assigning a desired function to the operation switch. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-110472 Summary of the Invention [Problem to be solved by the invention]

[0010] In the excavator of Patent Document 1, it is possible to selectively assign one of a plurality of functions to an operation switch. However, unless the operator knows which function to assign to the operation switch (input device) provided on the operation lever and to the input devices provided on equipment other than the operation lever in order to improve work efficiency, he or she cannot make an appropriate assignment. Furthermore, if the operator does not assign an appropriate function, there is a risk that work efficiency will actually decrease.

[0011] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an information input system for a work machine that is capable of suggesting to an operator appropriate function allocations to input devices provided on the control levers of the work machine or to input devices provided on equipment other than the control levers.

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, the same components are denoted by the same reference numerals, and duplicated descriptions will be omitted as appropriate.

[0016] FIG. 1 is a schematic view of a hydraulic excavator, an example of a work machine. The hydraulic excavator 1 is composed of an articulated front working implement 1A consisting of a boom 1a, an arm 1b, and a bucket 1c, each of which rotates vertically, and a vehicle body 1B consisting of an upper rotating body 1d and a lower traveling body 1e. A driver's cab 1f is provided on the upper rotating body 1d. The base end of the boom 1a of the front working implement 1A is supported on the front part of the upper rotating body 1d. The boom 1a, the arm 1b, the bucket 1c, the upper rotating body 1d, and the lower traveling body 1e are driven by actuators for a boom cylinder 2a, an arm cylinder 2b, a bucket cylinder 2c, a swing motor 3d, and left and right traveling motors 3e, 3f, respectively.

[0017] The upper rotating body 1d is equipped with an engine 4, which is the prime mover for operating the hydraulic excavator 1, a pump 5, and a valve 6 (shown in Figure 4). The pump 5 is driven by the rotation of the engine 4 and discharges hydraulic oil. The valve 6 controls the flow rate of hydraulic oil according to input from operation levers 7a, 7b, 7c, and 7d (shown in Figure 2) installed in the operator's cab 1f, and operates each actuator.

[0018] Angle sensors 8a, 8b, and 8c that detect the respective rotation angles are attached to the boom 1a, arm 1b, and bucket 1c. GNSS antennas 9a and 9b that acquire the position of the hydraulic excavator 1 are attached to the left and right sides of the upper rotating body 1d. Cameras 10a, 10b, and 10c that capture images of the surroundings of the hydraulic excavator 1 are attached to the left, rear, and right sides of the upper rotating body 1d.

[0019] FIG. 2 is an interior view of the operator's cab 1f. The operator's cab 1f is equipped with work operation levers 7a, 7b for operating the front work implement 1A and the upper revolving body 1d, travel operation levers 7c, 7d for operating the lower traveling body 1e, a shutoff lever 18 for disabling operation of the vehicle body using the operation levers 7a, 7b, 7c, 7d, a speaker 11 for audibly transmitting information to the operator, and a monitor 12 as a notification device for notifying the operator of information. In this embodiment, the speaker 11 is built into the monitor 12, but the speaker's location is not limited thereto as long as it can transmit audible information to the operator. Furthermore, the monitor 12 in this embodiment is equipped with a touch panel 15 as an input device for instructing the execution of functions implemented in the hydraulic excavator 1.

[0020] 3 is a schematic diagram of the work operation levers 7a, 7b. The work operation levers 7a, 7b are provided with lever switches 17a, 17b as input devices for issuing commands to execute functions implemented in the hydraulic excavator 1. In this embodiment, one lever switch is provided on each of the operation levers 7a, 7b, but the number of lever switches is not limited to this.

[0021] 4 is an overall configuration diagram of the control system of the hydraulic excavator 1. The control device 100 of the hydraulic excavator 1 has a main controller unit 50, a GNSS controller unit 40 that processes information from the GNSS antennas 9a and 9b, and a notification controller unit 60 that controls various notifications to the operator.

[0022] The main controller unit 50 performs engine control, pump control, etc. The main controller unit 50 is connected to the key cylinder 14, and performs electrical startup of the hydraulic excavator 1 and starting of the engine 4, etc. The main controller unit 50 is also connected to the communication terminal 16, and communicates with various terminals and servers outside the hydraulic excavator 1. The notification controller unit 60 calculates display information for the monitor 12 and sound information for the speaker 11 based on the processing status of the main controller unit 50, and transmits these to the monitor 12 and the speaker 11. Furthermore, the notification controller unit 60 transmits various setting signals to the main controller unit 50 in accordance with inputs from the touch panel 15 and lever switches 17a, 17b.

[0023] The work machine information input system 200 in this embodiment includes a control device 100, lever switches 17a and 17b, a touch panel 15, and a monitor 12.

[0024] 5 is a functional block diagram of control device 100. Control device 100 includes function determination unit 101, function assignment storage unit 102, function execution unit 103, notification content creation unit 104, operation information collection unit 105, and function assignment proposal unit 106. Each block will be described below.

[0025] The function allocation storage unit 102 stores combinations (function allocation patterns) of functions with the lever switches 17a and 17b and the touch panel 15. A plurality of function allocation patterns may be stored, and the patterns may be changed by the operator.

[0026] The function determination unit 101 determines the function assigned to the operated lever switch 17a, 17b or touch panel 15 based on the function assignment pattern stored in the function assignment storage unit 102. If multiple function assignment patterns are stored in the function assignment storage unit 102, the determination is made based on the currently set function assignment pattern. Details of the function assignment patterns will be described later.

[0027] The function execution unit 103 executes the function determined by the function determination unit 101 .

[0028] The notification content creation unit 104 creates notification content for notifying the execution result of the function execution unit 103 and outputs it to the monitor 12.

[0029] Based on the result of the determination by the function determination unit 101, the operation information collection unit 105 collects operation information of each device (the lever switches 17a and 17b and the touch panel 15).

[0030] The function allocation proposing unit 106 proposes function allocation to each device based on the operation information collected by the operation information collecting unit 105.

[0031] The notification content creation unit 104 creates notification content for notifying the proposal of the function allocation proposal unit 106 and outputs it to the monitor 12 .

[0032] FIG. 6 is a diagram showing an example of a function allocation pattern. The function allocation pattern 110 shows the combination of the lever switches 17a and 17b and the touch panel 15 with each function. In this embodiment, the air conditioner ON / OFF function and the radio ON / OFF function are assigned to the touch panel 15, the camera switching function is assigned to the lever switch 17a, and the wiper function is assigned to the lever switch 17b. The functions assigned to the touch panel 15 will be described later together with the display method on the monitor 12. The camera switching function is a function that switches the display pattern of the camera image displayed on the monitor 12. When images acquired from the cameras 10a, 10b, and 10c are displayed on the monitor 12, the operator can switch the display pattern from several display patterns with different display methods to suit the work being performed. The wiper function is a function that operates the wiper provided on the front window of the hydraulic excavator 1.

[0033] 7 is a diagram showing an example of the display on the monitor 12. Monitor display 400A is the display when the air conditioner and radio are on, and monitor display 400B is the display when the air conditioner and radio are off. Monitor 12 displays a fuel gauge 401 that shows the remaining fuel, a clock 402 that shows the current time, a mode icon 403 that shows the vehicle mode, a water temperature gauge 404 that shows the temperature of the coolant in the engine 4, and a camera image 405 of the vehicle surroundings.

[0034] Air conditioner temperature display 406 and radio volume display 407 also function as switches that can be tapped. Air conditioner temperature display 406 displays the set temperature when the air conditioner is on, and can output an instruction to switch the air conditioner to OFF by tapping the display area. Radio volume display 407 displays the set volume when the radio is on, and can output an instruction to switch the radio to OFF by tapping the display area.

[0035] Air conditioner OFF display 408 and radio OFF display 409 also function as switches that can be tapped. Air conditioner OFF display 408 displays the OFF state of the air conditioner, and by tapping the display area, it is possible to output an instruction to switch the air conditioner to ON. Radio OFF display 409 displays the OFF state of the radio, and by tapping the display area, it is possible to output an instruction to switch the radio to ON.

[0036] FIG. 8 is a flowchart showing the processing of the control device 100 when a function assigned to the lever switches 17a and 17b or the touch panel 15 is executed.

[0037] First, in step S300, it is determined whether or not lever switches 17a, 17b or touch panel 15 have been operated. If the determination result in step S300 is false, the flow ends.

[0038] If the determination result in step S300 is true, the function (hereinafter, function F) assigned to the operated device (lever switch 17a, 17b or touch panel 15) is determined based on the function assignment pattern 110 (step S301).

[0039] Following step S301, function F is executed (step S302). When the air conditioner ON / OFF function is executed, the air conditioner operates or stops, when the radio ON / OFF function is executed, the radio operates or stops, when the wiper function is executed, the wipers operate or stop, and when the camera switching function is executed, the display pattern of the camera image switches.

[0040] Following step S302, the execution result of function F is notified to the operator (step S303), and the flow ends. This allows the operator to understand the execution result of function F.

[0041] FIG. 9 is a flowchart showing the processing of the control device 100 when proposing functions to be assigned to the lever switches 17a and 17b.

[0042] First, in step S310, it is determined whether or not the lever switches 17a, 17b or the touch panel 15 has been operated. If the determination result in step S310 is false, the flow ends.

[0043] If the determination result in step S310 is true, the function assigned to the operated device (the lever switch 17a, 17b or the touch panel 15) is determined (step S311).

[0044] Following step S311, it is determined whether the operated device is either the lever switch 17a or 17b (step S312).

[0045] If the determination result in step S312 is true, the number of times that the function assigned to the operated lever switch among the functions assigned to the lever switches 17a and 17b (hereinafter referred to as functions Xa and Xb) is executed is counted (step S313).

[0046] If the determination result in step S312 is false, the number of times the function assigned to touch panel 15 (hereinafter, function Y) is executed is counted (step S314).

[0047] Following step S313 or step S314, it is determined whether a proposal to assign function Y to either of the lever switches 17a and 17b (hereinafter, proposal P) is necessary (step S315). The details of step S315 will be described later. If the determination result of step S315 is false, the flow ends.

[0048] If the determination result in step S315 is true, it is determined whether or not there is a history of proposal P being rejected (step S316). If the determination result in step S316 is false, the flow ends. This makes it possible to prevent proposals P that have been rejected by the operator in the past from being repeatedly notified to the operator.

[0049] If the determination result in step S316 is true, the proposal P is notified to the operator (step S317).

[0050] Following step S317, it is determined whether the proposal P has been accepted by the operator (step S318).

[0051] If the determination result in step S316 is false, the proposal P is stored as a rejected proposal (step S319), and the flow ends.

[0052] If the determination result in step S316 is true, the function allocation is changed to match the proposal P (step S320), and the flow ends. This makes it possible to execute function X, which is executed more frequently than function Y, through the operation of either lever switch 17a or 17b, which places less burden on the operator.

[0053] The above describes an example in which, when the execution frequency of function Y assigned to touch panel 15 is higher than the execution frequency of either of functions Xa and Xb assigned to lever switches 17a and 17b, respectively, a suggestion is notified to assign function Y assigned to touch panel 15 to a lever switch to which a function executed less frequently than function Y is assigned. However, a suggestion may also be notified to assign one of functions Xa and Xb executed less frequently than function Y to touch panel 15. Furthermore, when the execution frequency of a function assigned to a lever switch on the opposite side of the operator's dominant hand is higher than the execution frequency of a function assigned to the lever switch on the dominant hand side, a suggestion may be notified to swap functions Xa and Xb assigned to lever switches 17a and 17b, respectively.

[0054] In this embodiment, the determination in step S315 is made according to the following conditional expression. C tn ≧ C lm + α nm (n,m=1,2) C t1 = Number of times the air conditioner ON / OFF function is executed C t2 = Number of times the radio ON / OFF function has been executed C l1 = Number of times the camera switching function is executed C l2 = Number of wiper operations α nm = constant C tnC represents the count of the number of times each function operated via the touch panel 15 has been executed. In the function allocation in this embodiment, the number of times the air conditioner ON / OFF function and the radio ON / OFF function have been executed is counted. lm represents the count of the number of times each function Xa, Xb operated via the lever switches 17a, 17b is executed, and in the function allocation in this embodiment, the number of times the camera switching function (function Xa) and the wiper function (function Xb) are executed is counted. In this embodiment, the number of times the function is executed after transitioning to the key-on state is counted, and the count is reset when the key is turned off. The timing of starting and ending the count may be changed depending on changes in the vehicle mode, etc., and is not limited to this.

[0055] α nm is a constant. This conditional expression makes a function allocation suggestion when the number of times the function operated via touch panel 15 is executed is a certain number of times more than the number of times either function Xa or Xb operated via lever switches 17a, 17b is executed. This conditional expression is an example, and the determination method and conditional expression are not limited to this.

[0056] In this embodiment, α nm The value of is set to 10 regardless of the values ​​of n and m. The number of times the camera switching function (function Xa) is executed is C. l1 5 times, and the number of times the radio ON / OFF function is executed is C t2 If the number of times is 20, the number of times the radio ON / OFF function is executed is C t2 is the number of times the camera switching function is executed, C l1 and a constant α nm Therefore, the determination result in step S315 is true, and in step S317, a proposal to assign the radio ON / OFF function to the lever switch 17a is notified. nm The value may be changed depending on n and m.

[0057] FIG. 10 is a diagram showing an example of the display on the monitor 12 when proposing a change in the function assigned to the lever switch 17a provided on the left work operation lever 7a. Monitor display 400C shows an example of the display when proposing a function assignment to the lever switch 17a. Monitor display 400C displays, as a lever schematic diagram 410, a diagram that simulates the left work operation lever 7a and lever switch 17a to which the function assignment is proposed. Displaying the schematic diagram makes it easy to understand which lever switch the function assignment is being proposed to. Displayed near the lever schematic diagram 410 are a current function name 411 indicating the currently assigned function and a proposed function name 412 indicating the function to be proposed to be assigned.

[0058] Along with these displays, a guide message 413 is displayed to inform the operator that a function allocation is being proposed, a change rejection button 414 for selecting whether or not to make changes to the proposed function allocation, and a change reflection button 415. If the operator operates the change rejection button 414, the function allocation proposal is rejected, and the camera switching function that was originally assigned to the lever switch 17a is maintained. If the change reflection button 415 is operated, the function allocation proposal is approved, and the radio on / off function is assigned to the lever switch 17a instead of camera switching.

[0059] This display does not need to be displayed immediately after the judgment in step S315, but may be displayed, for example, when the shutoff lever 18 switches from an unlocked state (a state in which the vehicle can be operated by operating the lever) to a locked state (a state in which the vehicle cannot be operated by operating the lever).

[0060] As described above, when an operator initially performs work with the camera switching function assigned to lever switch 17a and the radio ON / OFF function assigned to touch panel 15, operation information for each device is collected, and if it is determined from the operation information for each device that the frequency of execution of the radio ON / OFF function is higher than the frequency of execution of the camera switching function, a suggestion is made to the operator to assign the radio ON / OFF function to lever switch 17a. As a result, the operator can improve work efficiency by assigning the frequently executed radio ON / OFF function to lever switch 17a, which requires less operation.

[0061] (summary) In this embodiment, the work machine information input system 200 includes a control device 100 that executes a plurality of functions of a hydraulic excavator 1 (work machine), lever switches 17a, 17b (first input devices) that are provided on operation levers 7a, 7b for operating the hydraulic excavator 1 and that instruct the control device 100 to execute one of the plurality of functions, and a touch panel 15 (second input device) that is provided on a monitor 12 (a device mounted on the hydraulic excavator 1 other than the operation levers 7a, 7b) and that instructs the control device 100 to execute one of the plurality of functions. The work machine information input system 200 includes a monitor 12 (notification device) that notifies information about the hydraulic excavator 1, and each of the lever switches 17a, 17b and the touch panel 15 can be selectively assigned any one of the plurality of functions, and the control device 100 collects operation information that indicates that any of the plurality of functions has been executed by operating the lever switches 17a, 17b and the touch panel 15, and outputs a proposal for a function to be assigned to the lever switches 17a, 17b or the touch panel 15 to the monitor 12 based on the collected operation information.

[0062] According to the present embodiment configured as described above, it is possible to suggest to the operator of the work machine 1 appropriate function allocation to the first input devices 17a, 17b provided on the operating levers 7a, 7b or the second input device 15 provided on equipment 12 other than the operating levers 7a, 7b, based on operation information from the first input devices 17a, 17b and the second input device 15, thereby making it possible to improve work efficiency.

[0063] In this embodiment, the equipment 12 other than the operation levers 7a, 7b on which the second input device 15 is provided is a monitor 12 installed in the operator's cab 1f of the work machine 1, and the second input device 15 is a touch panel 15 provided on the monitor 12. This makes it possible to interchange the functions assigned to the operation lever switches 17a, 17b and the functions assigned to the touch panel 15 provided on the monitor 12.

[0064] Furthermore, the operation information collected by the control device 100 in this embodiment is the number of times that functions assigned to the first input devices 17a and 17b and the second input device 15 have been executed. This makes it possible to propose function assignments to the first input devices 17a and 17b and the second input device 15 based on the execution frequencies of the functions assigned to the first input devices 17a and 17b and the second input device 15, respectively.

[0065] Furthermore, the control device 100 in this embodiment determines whether the difference obtained by subtracting the number of times the function assigned to the first input device 17a, 17b is executed from the number of times the function assigned to the second input device 15 is executed is equal to or exceeds a predetermined threshold value (=α nm ) or more, it is suggested that the function assigned to the second input device 15 be assigned to the first input devices 17a and 17b. This makes it possible to assign frequently executed functions to the first input devices 17a and 17b provided on the operating levers 7a and 7b.

[0066] Furthermore, the control device 100 in this embodiment starts counting the number of times the functions assigned to the first input devices 17a, 17b and the second input device 15 have been executed when the work machine 1 transitions to a predetermined mode, and resets the number of times the functions assigned to the first input devices 17a, 17b and the second input device 15 have been executed when the work machine 1 leaves the predetermined mode. This makes it possible to improve work efficiency when the work machine 1 is in the predetermined mode.

[0067] Furthermore, the control device 100 in this embodiment outputs the notification content to the notification device at the timing when the work machine 1 switches from a key-off state to a key-on state, or at the timing when the shut-off lever 18 installed in the operator's cab 1f of the work machine 1 switches from an unlocked state to a locked state. This makes it possible to prevent function allocation changes from being made in the middle of work, as a change to function allocation is suggested immediately before or after work starts.

[0068] Furthermore, the control device 100 in this embodiment includes, in the notification content output to the notification device 12, the name of the function assigned to the first input device 17a, 17b or the second input device 15 (current function name 411) and the name of the function proposed to be assigned to the first input device 17a, 17b or the second input device 15 (proposed function name 412). This allows the operator to easily understand the content of the proposed function assignment.

[0069] Furthermore, in the present embodiment, if there is a history of a proposal for a function to be assigned to the lever switches 17a, 17b or the touch panel 15 being rejected, the control device 100 does not output the proposal to the monitor 12 (notification device). This makes it possible to prevent the operator from being repeatedly notified of proposals that have been rejected by the operator in the past.

[0070] Furthermore, the control device 100 in this embodiment outputs a schematic diagram of the operating levers 7a and 7b, which shows the arrangement of the lever switches 17a and 17b, to the monitor 12 (notification device) together with the proposal of functions to be assigned to the lever switches 17a and 17b (first input device). This makes it possible to clearly communicate to the operator which lever switches 17a and 17b are being proposed to be assigned functions.

[0071] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments and includes various modifications.
