Various actuators such as the swing cylinder, the boom cylinder 24, the arm cylinder 26, and the bucket cylinder 27 are operated by control valves (control valves) capable of supplying hydraulic oil to the actuators. Further, the flow rate of hydraulic oil to the control valve is changed by adjusting the pilot pressure to the control valve by operation of an operation member described later and an electromagnetic proportional valve.

As shown in FIG. 1, the backhoe 2 is provided with a control device 30 for controlling the backhoe 2, and the control device 30 and the display device 3 include a CAN (Controller Area Network) and a FlexRay (FlexRay). ) Etc., mutual communication (data exchange) can be performed.
The control device 30 in this embodiment performs various controls such as auto idle control (AI control), flow rate control, boom height control, and arm height control.

In the display device 3, setting contents that have already been set, such as setting contents for determining whether or not to activate each control in the control apparatus 30 (control presence / absence setting) and changing a setting value such as an upper limit value and a lower limit value in each control. (Presence / absence of control, set value) can be changed.
Next, each control in the control device 30 and change of setting contents in the display device 3 will be described. In addition, each control which the control apparatus 30 performs in the working machines 2, such as the backhoe 2, is not limited to what is demonstrated below.

  The AI control and the flow rate control are performed by one control device (referred to as a first control device) 30A configured by a CPU or the like. The first control device 30A includes operation amounts of operation members (for example, an operation lever 26 and an operation switch) for operating various actuators such as a swing cylinder, a boom cylinder 24, an arm cylinder 26, and a bucket cylinder 27, and a governor angle from a governor sensor. Various control signals such as (the governor position), the operation amount (angle) of the accelerator lever, the on / off signal of the idle switch (AI-SW), and the engine speed from the engine rotation sensor are input.

In the AI control, when an operation member for operating the arm 23 (arm cylinder 26), the boom 20 (boom cylinder 24) or the like is operated, the engine speed is increased or decreased according to the operation amount of the accelerator lever. When is not operated, the engine speed is fixed to the idling state.
Specifically, in the AI control by the first control device 30A, when an idle switch ON signal is input with the operation lever 33 in the neutral position, an idle signal is sent to the auto idle motor regardless of the operation amount of the accelerator lever. Outputs and drives the auto idle motor to set the engine speed to the idle speed. In the AI control by the first control device 30A, when the control lever 33 is swung back and forth or left and right and an idle switch OFF signal is input, an operation signal is output to the auto idle motor based on the accelerator position signal. Drive the idle motor. When the auto idle motor is driven, the governor lever is actuated and the engine speed becomes the speed corresponding to the accelerator lever.

In the flow rate control, the actuator is operated according to the operation amount of the operation member.
In the flow control by the first control device 30A, for example, when the operation lever 33 is swung to one side (left side) from the neutral position and the left operation amount is input, a predetermined value is applied to the solenoid of the electromagnetic proportional valve corresponding to the operated actuator. Current (actuation signal) is output. Then, the electromagnetic proportional valve opens according to the current value, the pilot pressure of the control valve corresponding to the operated actuator is controlled, and the actuator operates in one direction. When the operation lever 33 is swung from the neutral position to the opposite side to the right side and the operation amount on the right side is input, the actuator is operated on the side opposite to the left side.

Boom height control and arm angle control (arm angle control) are performed by a control device (second control device) 30B different from the first control device 30A. Various control signals such as an arm angle and a boom angle are input to the second control device.
The boom height control stops the raising operation of the boom 22 regardless of the operation of the operation lever 33 when the height of the boom 22 reaches a preset upper limit value of the boom height. In the control of the second control device 30B, the height of the boom 22 is replaced with the boom angle, and the height of the boom 22 is determined based on the boom angle. Specifically, in the boom height control by the second control device 30B, when the boom 22 is raised by the operation lever 33, the boom angle is input to the second control device 30B. When the boom angle input to the second control device 30B reaches the upper limit value, the second control device 30B applies pilot pressure (pilot oil) to the control valve that supplies hydraulic oil to the boom cylinder 24. The boom raising operation is stopped by demagnetizing the solenoid proportional valve or solenoid of the solenoid valve.

  The arm angle control stops the scraping operation of the arm 23 regardless of the operation of the operation lever 33 when the arm angle reaches an upper limit value or a lower limit value of a preset arm angle (arm angle). It is. Specifically, in the arm angle control by the second control device 30B, the arm angle is input to the second control device 30B when the arm 23 is scraped by the operation lever 33. When the arm angle input to the second control device 30B reaches the upper limit value or the lower limit value, the second control device 30B controls the pilot pressure ( The scraping operation of the arm 23 is stopped by demagnetizing the solenoid proportional valve or the solenoid of the solenoid valve that supplies the pilot oil.

The display device 3 is configured to receive information (data) related to the work machine 21. That is, data input to the first control device 30A and the second control device 30B is input to the display device 3 via CAN communication, and other data such as setting values necessary for display and setting are input. It is like that.
FIG. 2 shows the display unit of the display device 3 as viewed from the front.

  The display unit 40 of the display device 3 includes a fixed display unit 40a that indicates the state of the backhoe 2 by turning on or off a lamp such as an LED, and a liquid crystal that displays various information by changing the display.

When the fifth switch 41e is pressed, the setting item N You can make a decision.

  Here, when changing the upper limit value or the lower limit value of the arm angle, as shown in FIG. 3C, the setting item N “arm limit setting” is selected on the setting screen M1. Then, as shown in FIG. 3 (d), a guidance display for guiding the arm to a new setting position (restricted position) is displayed on the setting screen M1. When the third switch 41c is pushed after coming to the position or the lower limit position, the upper limit value or lower limit value of the arm angle can be changed.

  When the setting of the upper limit value and the lower limit value of the arm angle is completed, as shown in FIG. 3E, a display indicating that the arm limit setting is completed is displayed on the setting screen M1. The changed set values (the upper limit value and the lower limit value of the arm angle) are stored in the storage unit 53 provided in any of the first control device 30A, the second control device 30B, and the display device 3. The control device 30 (30B) changes the setting of the arm angle according to the upper limit value and the lower limit value of the arm angle stored in the storage unit 53.

FIG. 4 shows the transition of the screen of the display device 3 when setting to enable or disable the angle control of the arm.
To enable or disable the arm angle control, first, while pressing the first switch 41a, perform a special operation of turning the ignition key from OFF to ON by rotating the engine start cylinder provided in the backhoe 2.

By selecting “valid” or “invalid” on the setting screen M1 and pressing the fifth switch 41e, the arm angle control can be validated or invalidated. The setting of whether the arm angle control is valid or invalid is stored in the storage unit 53. The control device 30 (30B) changes the arm angle setting in accordance with the arm angle control valid / invalid setting stored in the storage unit 53.

FIG. 5 shows the transition of the screen of the display device 3 when changing the idle speed in the AI control.
In order to change the idle speed, first, as shown in FIG. 5A, the first switch 41a is pushed in the state where the display device 3 is in the normal screen mode, and the display device 3 is changed from the normal screen mode to the setting screen mode. As shown in FIG. 5B, the liquid crystal display unit 40b is set to the setting screen M1. Then, as shown in FIG. 5C, the setting item N “AI control” is selected on the setting screen M1. Then, as shown in FIG. 5D, the setting screen M1 becomes a screen for setting the idle rotation speed, and the value of the idle rotation speed displayed on the setting screen M1 is changed (increased or decreased) by the operation of the switch 41 or the like. ). Here, when the third switch 41c is pressed, the value (set value) of the changed idle speed displayed on the setting screen M1 becomes the new idle speed.

  When the idling speed is changed on the setting screen M1, as shown in FIG. 5E, the setting screen M1 displays guidance for setting the accelerator (accelerator lever) to the maximum (MAX) position. When the accelerator is at the maximum position, guidance for setting the accelerator to the idling position is displayed on the setting screen M1, as shown in FIG. When the accelerator is set to the idling position, as shown in FIG. 5G, a display indicating that the setting of the idle speed has been completed is made on the setting screen M1. The changed idle speed (set value) is stored in the storage unit 53. Control device 30 (30A) changes the setting of AI control according to the idle speed stored in storage unit 53.

  As described above, in the display device 3, various setting contents in the backhoe 2 are changed, such as changing the upper limit value or lower limit value of the arm angle, switching the arm angle control to be valid or invalid, and changing the idle speed in the AI control. It can be performed. In other words, the setting content of the backhoe 2 can be changed by the control device 30 by executing the program stored in the control device 30 and operating the display device 3 as described above.

As described above, in the present invention, the setting content can be changed not only through the display device 3 but also through the mobile terminal 4. This point will be described in detail using the display device 3 and the portable terminal 4.
As shown in FIG. 1, the control device 30 (the first control device 30 </ b> A or the second control device 30 </ b> B) is provided with means for changing the setting contents via the display device 3.

  Specifically, a change command transmission unit 50 and a content reception unit 51 are provided in the first control device 30A as means for changing the setting content. Further, content storage means (storage unit) 53 for storing the changed setting content is provided in the first control device 30A. The change command transmission unit 50 and the content reception unit 51 are configured by a program or the like stored in the first control device 30A.

Programs constituting the change command transmission unit 50 and the content reception unit 51 may be stored not only in the first control device 30A but also in the second control device 30B and the display device 3. In other words, the second control device 30 </ b> B and the display device 3 may include the change command transmission unit 50 and the content reception unit 51.
Hereinafter, the setting change through the display device 3 will be described with reference to FIG.

The change command transmission means 50 transmits a change command signal for instructing the portable terminal 4 to change the setting contents.
As shown in FIG. 6, when a request for changing the setting is made by wireless communication from the portable terminal 4 to the control device 30 via the display device 3 (transmission / reception unit) by operating the portable terminal 4, the change command transmission means In response to a setting change request from the mobile terminal 4, 50 transmits a change command signal if the setting can be changed.

For example, when the operation lever is being operated, the accelerator lever is being operated, and the backhoe 2 is being operated by the operator, the change command transmission means 50 sends the change command signal to the portable terminal via the transmission / reception unit. Do not send to 4. On the other hand, the change command transmission means 50 transmits a change command signal to the portable terminal 4 when the operation lever is not operated or the accelerator lever is not operated, that is, when the backhoe 2 is not being operated. Backhoe 2
Can be determined by information such as a sensor input to the control device 30.

Here, when transmitting the change command signal to the portable terminal 4, the change command transmission unit 50 may transmit the setting content already stored in the content storage unit 53 together with the change command signal.
For example, when the display device 3 has already stored the setting contents such as “Yes” for the arm angle control and “1050 rpm” for the idle rotation speed in the content storage means 53 (the storage unit of the display device 3), The same setting contents as the setting contents stored in the contents storage means 53 (the arm angle control is “present” and the idle speed is “1050 rpm”) are transmitted to the portable terminal 4. In this way, the setting value of the backhoe 2 can be confirmed on the mobile terminal 4 side, and the setting value can be changed while viewing the setting value already set on the backhoe 2 side.

Further, when the portable terminal 4 does not have a program (setting control program) for displaying the setting screen M1 for changing the setting content, the change command transmission means 50 passes the setting control program through the display device 3. You may transmit with a change command signal.
For example, when a request for changing the setting is made from the mobile terminal 4 to the control device 30 (the first control device 30A and the second control device 30B) via the display device 3, the mobile terminal 4 has a setting control program. If the change command transmission unit 50 is notified that the change has not been made, the change command transmission unit 50 receives the notification and transmits the setting control program to the portable terminal 4. In this way, the backhoe 2 can be set even if the portable terminal 4 does not have a setting control program. Note that the setting content stored in the content storage means 53 may be transmitted when the setting control program is transmitted to the portable terminal 4.

  The content receiving means 51 (content acquisition means) receives (acquires) the setting content changed on the portable terminal 4 side in response to the change command signal. For example, when the setting screen M1 is displayed on the mobile terminal 4 side, the setting of the backhoe 2 is completed, and the setting content changed on the mobile terminal 4 side is transmitted to the content receiving means 51, as shown in FIG. The content receiving means 51 receives the changed setting content transmitted from the portable terminal 4 via the display device 3, and temporarily holds the setting content.

Here, when the setting content transmitted from the mobile terminal 4 is received, for example, when the backhoe 2 is in operation and the load on the control processing of the control device and the display processing on the display device 3 is high, the content In order to give priority to control processing and display processing, the receiving means 51 divides the setting contents without receiving them continuously and receives them intermittently at time intervals.
Alternatively, under a situation where the load of the control process and the display process is high, the content receiving unit 51 temporarily stops receiving the setting content, and transmits the setting content to the portable terminal 4 when the processing load becomes low. After the request, the setting content transmitted from the portable terminal 4 is received again.

  The content storage unit 53 stores the setting content changed on the mobile terminal 4 side as a new setting content. For example, when the backhoe 2 is not in operation, that is, when the load of control processing or display processing is low, the content storage means 53 receives content from the stored settings as shown in FIG. The new setting contents fetched by the means 51 are rewritten. During rewriting of the setting contents, it is preferable to temporarily disable the backhoe 2.

  Here, when the setting content received by the content receiving unit 51 is stored as new setting content by the content storage unit 53, the setting content received by the content receiving unit 51 and the setting content transmitted from the portable terminal 4 are collated. It is preferable. For example, after the setting content is received by the content receiving means 51, the received setting content is returned (transmitted) from the control device 30 to the portable terminal 4 via the display device 3. For convenience of explanation, the setting content returned from the display device 3 (control device 30) is referred to as collation setting content.

  On the mobile terminal 4 side, the collation setting content transmitted from the display device 3 (control device 30) is collated with the setting content (setting content for transmission) set in the mobile terminal 4 and transmitted to the display device 3. If the two contents match, a match signal indicating the contents match is transmitted from the portable terminal 4 to the control device 30 via the display device 3. On the content storage means 53 side, when the coincidence signal is received, the setting content already transmitted from the portable terminal 4 is stored as new setting content.

If the collation setting content and the transmission setting content do not match, the portable terminal 4 transmits a mismatch signal indicating content mismatch to the control device 30 via the display device 3. On the control device 30 side, when the mismatch signal is received, the setting contents already transmitted from the portable terminal 4 are not stored as new setting contents, and the contents receiving unit 51 requests the portable terminal 4 to transmit the setting contents again. Then, the portable terminal 4 resends the setting contents in response to the retransmission request. That is, the display device 3 (control device 30) and the mobile terminal 4 collate whether or not the setting contents match, and the process is repeated until the collation matches.

  In FIG. 6, a setting change request is sent from the mobile terminal 4 to the control device 30, and the control device 30 transmits a change command signal based on the request from the mobile terminal 4. Further, on the mobile terminal 4 side, In response to the change command signal transmitted from the control device 30, the setting content set on the mobile terminal 4 side is transmitted to the control device 30. However, as shown in FIG. 9, a setting change request from the mobile terminal 4 to the control device 30, transmission of a change command signal from the control device 30 to the mobile terminal 4 based on this request, and from the mobile terminal 4 to the control device The control device 30 may directly receive the setting content transmitted from the mobile terminal 4 without performing a response to the change command signal to 30. For example, when the data amount of the setting content transmitted from the portable terminal 4 to the control device 30 is small, a method as shown in FIG. 9 may be performed.

Next, content setting by the portable terminal 4 will be described with reference to FIGS.
As shown in FIG. 1, the mobile terminal 4 includes a setting screen display unit 60, a change unit 61, and a setting content transmission unit 62. The setting screen display means 60, the changing means 61, and the setting content transmission means 62 are composed of programs stored in the mobile terminal 4. Moreover, the portable terminal 4 has a display unit 63 for displaying the setting screen M1. The display unit 63 may be a touch panel type as described later, or may be a non-touch panel type as long as it can display various information.

  The setting screen display means 60 displays a setting screen M1 for changing the setting contents in response to the change command signal on the display unit 63. For example, when the change command signal transmitted from the control device 30 via the display device 3 is received, the setting screen display means 60 activates a setting control program for displaying the setting screen M1 and displays the display unit of the portable terminal 4. A setting screen M1 is displayed at 63.

  Here, when the setting control program is already stored in the portable terminal 4, the setting screen display means 60 activates the stored setting control program and displays the setting screen M1 on the display unit. On the other hand, when the setting control program is not provided, the setting screen display means 60 downloads the setting control program transmitted together with the change command signal from the display device 3 (control device 30), and downloads the downloaded setting program. The control program is activated to display the setting screen M1 on the display unit.

As described above, the setting screen M1 on the portable terminal 4 may be the same screen (characters, numerical values, designs, sizes, display ranges, etc. are exactly the same) as the setting screen M1 of the display device 3. It is good also as a screen which put together the display divided into multiple in the setting screen M1.
Specifically, as shown in FIG. 7, for example, on the setting screen M1 of the portable terminal 4, a list of all setting items N is displayed on the left side, and each setting item N is already set on the center. The setting content (existing setting content) is displayed, the changed setting content (setting content set in the mobile terminal 4) is displayed on the right side, and guidance (message) is displayed on the lower side. That is, the mobile terminal 4 divides one setting screen M1 into a plurality of areas, and displays a list of setting items, existing setting contents, changed setting contents, messages, etc. in each divided area. . For convenience of explanation, the first area Q1 is a part for displaying a list of setting items, the second area Q2 is a part for displaying existing setting contents, the third area Q3 is a part for displaying changed setting contents, and a guidance is displayed. The part to be referred to is called the fourth area Q4.

When the setting screen display means 60 has received the setting content already stored in the content storage means 53 together with the change command signal from the control device 30, the setting screen display means 60 displays the received existing content in the second area Q2. If the setting contents are not received, the existing setting contents are not displayed in the second area Q2.
The change means 61 changes the setting content displayed on the setting screen M1.

For example, when the display unit of the portable terminal 4 is a touch panel type, when the setting content corresponding to the setting item displayed in the third area is touched (touched) with the finger, the changing unit 61 sets the touched setting. The setting contents corresponding to the item are popped up on the setting screen M1, and the setting contents can be changed on the pop-up screen.
For example, when the idling speed setting content is touched in the third area, the changing means 61 causes the idling speed to be displayed on the pop-up screen. On this pop-up screen, the changing means 61 automatically displays a numeric keypad for changing the value of the idle rotation speed. By operating the numeric keypad on the pop-up screen on which the numeric keypad is displayed, the idle rotation speed can be changed.

  Further, when the setting content (valid or invalid) of the arm restriction setting is touched in the third area, the changing means 61 displays the validity or invalidity of the arm angle control on the pop-up screen. In this pop-up screen, the change means 61 changes the setting to “invalid” by touching “valid” when “valid” is already displayed, and changes to “invalid” when “valid” is already displayed. Touch [Disable] to change the setting to [Enable].

  As described above, the changing unit 61 can freely change the setting contents displayed on the setting screen M1. Although the touch panel has been described as an example, the changing unit 61 may change the setting content displayed on the setting screen M1 by operating a switch or the like, or the setting content may be changed by voice or the like. As long as the setting contents can be changed, the changing means 61 may be any type.

  The setting content transmitting means 62 transmits the setting content changed on the setting screen M1 to the display device 3 (control device 30). For example, when the display indicating the completion of setting displayed on the setting screen M <b> 1 is touched on the mobile terminal 4, the setting content changed by the changing unit 61 is transmitted to the control device 30 via the display device 3. The setting content transmitting means 62 transmits the setting content to the display device 3 (control device 30) when there is an instruction to complete the setting. Note that the setting completion instruction method may be a method of touching a display indicating the completion of setting as described above, a switch or the like, or a voice.

  As described above, the mobile terminal 4 may include a content verification unit that performs verification between the verification setting content transmitted from the display device 3 (control device 30) and the transmission setting content from the mobile terminal 4 side. Good. In this case, the portable terminal 4 transmits a coincidence signal indicating content coincidence to the display device 3 (control device 30) if the setting contents match, and if the setting contents do not coincide, the portable terminal 4 sends a disagreement signal indicating content disagreement. It transmits to the display apparatus 3 (control apparatus 30). If the setting contents do not match, the setting contents transmitting unit 62 resends the setting contents in response to the retransmission request transmitted from the display device 3 (control device 30). The setting content transmitting unit 62 transmits the setting content until the setting content matches.

  According to the present invention, since the change command transmission means 50, the content reception means 51, and the content storage means 53 are provided, the operator who operates the work machine 2 holds the portable terminal 4 while holding the portable terminal 4. The setting contents of the work machine 2 can be easily changed by simply operating the terminal 4. In addition, since the change command transmission unit 50 is configured to transmit the setting content already stored on the work machine 2 side to the portable terminal 4, when the operator changes the setting, the setting content before the change is set. Since it is possible to change the new setting contents while watching the above, it is easy to make a policy on how to change the setting contents from the current state, and the setting can be easily performed from this point.

Furthermore, since the change command transmission unit 50 is configured to transmit a program (setting control program) for displaying the setting screen M1 to the portable terminal 4, the portable terminal 4 owned by the operator controls the setting. Even if you do not have a program, you can change the settings.
In addition, according to the present invention, it is provided with the content collating means for collating the setting content for collation with the setting content for transmission from the portable terminal 4 side, and the content storage means 53 is carried when the collation of the setting content is established. Since the setting contents transmitted from the terminal 4 are stored as new setting contents, for example, the setting contents do not match due to a communication error between the display device 3 (control device 30) and the portable terminal 4. Can be prevented, and the reliability of changing the setting contents by the portable terminal 4 can be improved.
