Summary of the Invention

Problems to be Solved by the Invention

[0004] Work machines are equipped with various functions including a function for detecting obstacles as described in Patent Document 1. Each function of the work machine can be set to ON or OFF by an operator via a setting screen displayed on a monitor provided in the cab of the work machine. Also, due to changes in the specifications of the work machine, the validity and invalidity of functions are switched or functions are added. In this case, it was necessary to update the software of the monitor controller in accordance with the specification changes.

[Modes for carrying out the invention]

[0010] The embodiments described below will be explained with reference to the drawings, but the disclosure is not limited thereto. The components of each embodiment described below can be combined as appropriate. In addition, some components may not be used.

[0011] In this embodiment, the work machine is, for example, a forklift, wheel loader, or hydraulic excavator driven by power from a battery or an engine, and is not particularly limited. In this embodiment, the work machine detects obstacles around it.

[0012] <Display system for industrial machinery> FIG. 1 is a schematic diagram of a display system according to the present embodiment. The display system 1 of the working machine is mounted on the working machine. The display system 1 includes a first controller 20 that performs peripheral monitoring control and a second controller 40 that performs display control. In the present embodiment, the display system 1 further includes a working machine controller 50 that performs working machine control. The first controller 20, the second controller 40, and the working machine controller 50 can communicate data.

[0013] The setting items are items that allow the operator of the working machine to set various functions of the working machine. The various settings are, for example, "ON" and "OFF" of the functions. The setting items are displayed on the setting screen of the monitor 31 (see FIG. 5) provided in the cab of the working machine. The operator changes the settings of the setting items on the setting screen of the monitor 31. Specific examples of the setting items in the present embodiment will be described later.

[0014] <Peripheral monitoring device> FIG. 2 is a functional block diagram showing an example of the first controller. The peripheral monitoring device 10 detects obstacles around the working machine. When an obstacle is detected around, the peripheral monitoring device 10 performs control such as stopping the machine body or sounding a buzzer, for example. The peripheral monitoring device 10 includes a first controller 20.

[0015] <First controller> The first controller 20 implements additional functions of the working machine such as peripheral monitoring control. The first controller 20 performs control different from that of the second controller. The first controller 20 has more software updates than the second controller 40. The first controller 20 is the controller of the peripheral monitoring device 10. The first controller 20 transmits setting information to the second controller 40. The first controller 20 includes an interface unit 21, a setting information generation unit 22, a setting information storage unit 23, a setting information transmission control unit 24, and a setting information reception control unit 25.

[0016] The interface unit 21 is connected to the display device 30. The interface unit 21 communicates with the display device 30.

[0017] The setting information generation unit 22 generates setting information that indicates the display mode for each setting item related to the work machine, based on the specifications of the work machine. The setting information generated by the setting information generation unit 22 is stored in the setting information storage unit 23.

[0018] Figure 3 is a diagram illustrating an example of setting information. The setting information is information indicating the display mode on the display device 30 for each setting item related to the work machine. In this embodiment, the setting information includes information indicating whether or not to display on the display device 30, whether or not the setting can be changed, the setting value, and the conditions for setting whether or not to change the setting for each setting item.

[0019] In this embodiment, the setting items correspond to functions related to the surrounding monitoring function of the surrounding monitoring device 10. In this embodiment, there are multiple setting items. For example, the setting items are "machine stop control," "external buzzer," and "cab buzzer." The setting items are functions that may be added or removed depending on changes in the specifications of the work machine.

[0020] "Aircraft stop control" is a control function that stops the aircraft when an obstacle is detected in the surrounding area by the surrounding monitoring device 10.

[0021] The "external buzzer" is a function that sounds a buzzer located on the outside of the work machine when an obstacle is detected in the surrounding area by the surrounding monitoring device 10.

[0022] The "cab buzzer" is a function that sounds a buzzer installed inside the driver's cab when an obstacle is detected in the surrounding area by the surrounding monitoring device 10.

[0023] "Display or non-display" refers to whether or not the setting item is displayed on the display device 30. If "Display enabled," the setting item is displayed on the settings screen of the monitor 31 of the display device 30. If "Do not display," the setting item is not displayed on the settings screen of the monitor 31.

[0024] For example, if the "aircraft shutdown control" function is disabled, in other words, if the function is not available, "aircraft shutdown control" will be displayed as "not displayed". For example, if the "aircraft shutdown control" function is enabled, in other words, if the function is available, "aircraft shutdown control" will be displayed as "displayed".

[0025] "Setting changeability" refers to whether or not the setting value of the setting item can be changed. More specifically, "setting changeability" refers to whether or not the operator can switch between "ON" and "OFF" for the function corresponding to the setting item. If "setting changeability" is enabled, the setting value of the setting item can be changed between "ON" and "OFF" via the setting screen of the monitor 31 of the display device 30. For example, to not sound the "external buzzer," set "external buzzer" to "OFF." For example, to sound the "external buzzer," set "external buzzer" to "ON." If "setting changeability" is disabled, the setting value of the setting item cannot be changed between "ON" and "OFF" via the setting screen of the monitor 31. In this embodiment, the setting value of a setting item may be automatically set by a combination of the setting values ​​of other setting items. Such conditions are called "permission setting conditions." Permission setting conditions are conditions that restrict the settings of multiple setting items.

[0026] The permission / failure setting conditions are, for example, conditions such as setting item "Function A" to "ON" and setting item "Function B" to "OFF". This permission / failure setting condition restricts setting item "Function B" to "ON" when setting item "Function A" is "ON". Similarly, the permission / failure setting conditions are, for example, conditions such as setting item "Function C" to "ON" when setting item "Function A" or "Function B" is "ON". This permission / failure setting condition restricts setting item "Function C" to "OFF" when setting item "Function A" or "Function B" is "ON". The permission / failure setting conditions are defined based on the specifications of the work machine.

[0027] In this embodiment, the setting information generation unit 22 generates such setting information based on the specifications of the work machine.

[0028] The setting information storage unit 23 stores setting information that indicates the display mode for each setting item related to the work machine. The setting information storage unit 23 stores the setting information generated by the setting information generation unit 22 as master data. The setting information to be stored will be described later. The setting information storage unit 23 may use at least one of the following: non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Random Only Memory), flash memory, EPROM (Erasable Programmable Random Access Memory), EEPROM (Electrically Erasable Programmable Random Access Memory), magnetic disks, flexible disks, and magneto-optical disks.

[0029] The setting information transmission control unit 24 controls the transmission of setting information to the second controller 40 via the interface unit 21. The setting information transmission control unit 24 transmits setting information, for example, when the work machine is started up.

[0030] The setting information receiving control unit 25 controls the receiving of setting information from the second controller 40 via the interface unit 21. The setting information receiving control unit 25 receives setting information, for example, when the display of the setting screen ends, when the setting value is changed, or when the work machine is finished. The setting information received by the setting information receiving control unit 25 is stored in the setting information storage unit 23. As a result, the setting information set by the operator via the setting screen of the monitor 31 of the display device 30 is stored in the setting information storage unit 23 as master data.

[0031] <Display device> Figure 4 is a functional block diagram showing an example of a display device including a second controller. The display device 30 displays various information about the work machine. The display device 30 displays, for example, video transmitted from the peripheral monitoring device 10. The display device 30 also displays, for example, setting items related to the work machine. The display device 30 comprises a monitor 31, an operation unit 32, and a second controller 40.

[0032] The monitor 31 is positioned, for example, in front of the operator's seat of the work machine. The monitor 31 includes a flat panel display such as a liquid crystal display or an organic EL display (electroluminescence). The monitor 31 displays, for example, video transmitted from the peripheral monitoring device 10. The monitor 31 also displays, for example, video of the settings screen for setting items related to the work machine.

[0033] The operation unit 32 is, for example, a touch panel superimposed on a liquid crystal display. In this embodiment, the operation unit 32 is, for example, button images 321, 322, 323, and 324 displayed on the settings screen. Button image 321 is a button that moves the selection position of a setting item on the settings screen downwards. Button image 322 is a button that moves the selection position of a setting item on the settings screen upwards. Button image 323 is a button that returns the selection position of a setting item on the settings screen to its original position. Button image 324 is a button that determines the selection position of a setting item on the settings screen. The operation unit 32 may also be, for example, a function switch located around the monitor 31.

[0034] <Second Controller> The second controller 40 implements the basic functions of the work machine. The second controller 40 undergoes fewer software updates than the first controller 20. The second controller 40 is, for example, the controller of the display device 30, in other words, the monitor controller. The second controller 40 receives setting information from the first controller 20. Based on the received setting information, the second controller 40 displays the setting items on the monitor 31. The second controller 40 displays, for example, video transmitted from the peripheral monitoring device 10 on the monitor 31. The second controller 40 comprises an interface unit 41, a setting information reception control unit 42, a display control unit 43, an operation reception unit 44, and a setting information transmission control unit 45.

[0035] The second controller 40 is connected to the monitor 31 and the operation unit 32. When the second controller 40 detects an operation on the operation unit 32, it performs control to acquire operation information. When the work machine is started, the second controller 40 performs control to display the setting information acquired from the first controller 20 on the monitor 31.

[0036] The interface unit 41 is connected to the peripheral monitoring device 10 and the work equipment controller 50. The interface unit 41 communicates with the peripheral monitoring device 10 and the work equipment controller 50. The communication with the work equipment controller 50 will not be explained.

[0037] The setting information receiving control unit 42 controls the receiving of setting information from the first controller 20 via the interface unit 41. The setting information receiving control unit 42 receives setting information, for example, when the work machine is started up. The setting information received by the setting information receiving control unit 42 is stored in a storage unit (not shown).

[0038] The display control unit 43 controls the output to the monitor 31. For example, the display control unit 43 outputs a video signal that displays video transmitted from the peripheral monitoring device 10 on the monitor 31. Based on the setting information acquired by the setting information reception control unit 42, the display control unit 43 outputs a video signal that displays the setting items on the monitor 31.

[0039] The display control unit 43 outputs a video signal for each setting item, based on the setting information received from the first controller 20, indicating whether or not to display, whether or not the setting can be changed, the setting value, and a setting screen corresponding to the setting conditions. For each setting item, if the display status is "display enabled," the setting item is displayed on the setting screen. For each setting item, if the setting change status is "setting change enabled," a setting change request is displayed on the setting screen. In this embodiment, the setting change request also functions as the setting value. If the display status is "display disabled," the setting item is hidden. The following applies to setting items that are "display enabled." If the setting change status is "setting change enabled," the setting values ​​"ON" and "OFF" for the setting item are displayed in a way that allows them to be changed. For example, the setting values ​​"ON" and "OFF" are displayed in a way that allows them to be switched each time they are pressed. In this embodiment, the setting values ​​"ON" and "OFF" for the setting item function as a setting change request. If the setting change status is "setting change disabled," the setting value for the setting item is displayed in a way that prevents it from being changed. Furthermore, based on the permission / rejection setting conditions, the setting value for whether a setting item can be changed is automatically set and displayed by combining it with the setting values ​​for other setting items.

[0040] Figure 5 is a diagram illustrating an example of the settings screen. The settings screen displayed on monitor 31 shows three setting items and their respective values. Button images 321, 322, 323, and 324 are displayed at the bottom of the settings screen. In the example shown in Figure 5, "Aircraft Stop Control" is set to "ON", "External Buzzer" is set to "ON", and "Cab Buzzer" is set to "ON".

[0041] The display control unit 43 updates the display of the settings screen based on the operation information acquired by the operation reception unit 44. For example, based on operation information to change a setting value, the display control unit 43 displays an image of the setting value of the relevant item on the settings screen that has been updated.

[0042] The display control unit 43 transmits setting information, including information about the setting values ​​on the current setting screen, to the first controller 20. More specifically, the display control unit 43 transmits setting information, including information about the setting values ​​on the current setting screen, to the first controller 20 via the setting information transmission control unit 45, for example, when it terminates the display of the setting screen or when a setting value is changed.

[0043] The operation reception unit 44 receives operations for the operation unit 32. The operation reception unit 44 acquires operation information. The operation reception unit 44 outputs the received operation information to the display control unit 43.

[0044] The setting information transmission control unit 45 controls the transmission of setting information to the first controller 20 via the interface unit 41. The setting information transmission control unit 45 transmits the setting information, for example, when the display of the setting screen ends, when the setting value is changed, or when the work machine is finished.

[0045] <Work equipment controller> The work equipment controller 50 is connected to the display device 30 via an interface unit (not shown). In this embodiment, the work equipment controller 50 controls functions related to the surrounding monitoring function of the surrounding monitoring device 10. For example, the work equipment controller 50 controls the stopping of the machine. For example, the work equipment controller 50 controls the sounding of an external buzzer. For example, the work equipment controller 50 controls the sounding of a buzzer inside the cab.

[0046] <Display system processing> Next, the method for displaying the working machine will be explained. First, when the working machine is started, the first controller 20 is controlled by the setting information transmission control unit 24 to transmit setting information to the second controller 40 via the interface unit 21.

[0047] Figure 6 is a flowchart showing an example of the processing of the display system 1 according to this embodiment. When the work machine is started, the second controller 40 receives setting information from the first controller 20 (step S11). More specifically, the second controller 40 is controlled by the setting information reception control unit 42 to receive setting information from the first controller 20 via the interface unit 41. The second controller 40 proceeds to step S12.

[0048] The second controller 40 displays the settings information (step S12). More specifically, based on the settings information received from the first controller 20, the second controller 40 outputs a video signal that displays a setting screen according to the setting conditions, indicating whether or not to display the setting, whether or not the setting can be changed, the setting value, and whether or not to display the setting for each setting item.

[0049] Then, for example, when the display of the settings screen ends, when the setting value is changed, or when the work machine is finished, the second controller 40 transmits setting information, including the information of the setting value on the current settings screen, via the setting information transmission control unit 45.

[0050] The first controller 20 then receives the setting information from the setting information receiving control unit 25. The first controller 20 stores the setting information received by the setting information receiving control unit 25 in the setting information storage unit 23.

[0051] In this way, the setting information changed via the setting screen displayed on the monitor 31 is transmitted from the second controller 40 to the first controller 20 and stored in the setting information storage unit 23. The setting information storage unit 23 stores the setting information as master data.

[0052] Figure 7 illustrates a specific example of the setting information. In Figure 7, "Aircraft Stop Control" is stored as "Display Enabled," "Setting Changeable," and "ON" as the set value. When it is "ON," the setting condition for enabling or disabling the cab buzzer is "ON." "External Buzzer" is stored as "Display Enabled," "Setting Changeable," and "ON" as the set value. When it is "ON," the setting condition for enabling or disabling the cab buzzer is "ON" as the set value. "Cab Buzzer" is stored as "Display Enabled," "Setting Change Not Enabled," and "ON" as the set value. Based on the setting information shown in Figure 7, the setting screen shown in Figure 5 is displayed.

[0053] Figure 8 is a diagram illustrating a specific example of setting information. Figure 9 is a diagram of the setting screen displayed based on the setting information in Figure 8. In Figure 8, "Aircraft Stop Control" is stored as "Not Displayed". "External Buzzer" is stored as "Displayed", "Setting Changeable", and "ON" as the set value. Also, when "ON", the setting value of the cab buzzer is "ON" as the permission setting condition. "Cab Buzzer" is stored as "Displayed", "Setting Change Not Possible", and "ON" as the set value. Based on the setting information shown in Figure 8, the setting screen shown in Figure 9 is displayed. In the example shown in Figure 9, "Aircraft Stop Control" is hidden, "External Buzzer" is set to "ON", and "Cab Buzzer" is set to "ON". In the example shown in Figure 9, according to the permission setting condition, when "External Buzzer" is "ON", "Cab Buzzer" is also set to "ON", and it is not possible to switch "Cab Buzzer" to "OFF".

[0054] Figure 10 is a diagram illustrating a specific example of setting information. Figure 11 is a diagram of the setting screen displayed based on the setting information in Figure 10. In Figure 10, "Aircraft Stop Control" is stored as "Not Displayed". "External Buzzer" is stored as "Displayed", "Setting Changeable", and "OFF" as the set value. Also, if "ON", the setting value of the cab buzzer is "ON" is the setting condition for enabling / disabling. "Cab Buzzer" is stored as "Displayed", "Setting Changeable", and "ON" as the set value. Based on the setting information shown in Figure 10, the setting screen shown in Figure 11 is displayed. In the example shown in Figure 11, "Aircraft Stop Control" is hidden, "External Buzzer" is set to "OFF", and "Cab Buzzer" is set to "ON". In the example shown in Figure 11, "External Buzzer" is "OFF" and "Cab Buzzer" is "ON". The "Cab Buzzer" can be switched to "OFF" based on the setting condition for enabling / disabling.

[0055] <Computer System> Figure 12 is a block diagram showing an example of a computer system 1000 according to this embodiment. The peripheral monitoring device 10 described above includes the computer system 1000. The computer system 1000 has a processor 1001 such as a CPU (Central Processing Unit), a main memory 1002 including non-volatile memory such as ROM and volatile memory such as RAM, a storage 1003, and an interface 1004 including input / output circuits. The first controller 20, the second controller 40, and the work machine controller 50 are numerical arithmetic units (processors) such as CPUs. The functions of each controller of the peripheral monitoring device 10 described above are stored as programs in the storage 1003. The processor 1001 reads the program from the storage 1003, loads it into the main memory 1002, and executes the above processing according to the program. The program may be distributed to the computer system 1000 via a network.

[0056] <Effects> As described above, in this embodiment, the first controller 20 stores the setting information as master data. In this embodiment, the second controller 40 displays the setting items on the setting screen based on the setting information received from the first controller 20. According to this embodiment, the setting screens for various functions of the work machine can be displayed appropriately. In this embodiment, if the setting items are changed, it is only necessary to change the setting information, which is the master data stored in the first controller 20. According to this embodiment, the second controller 40 does not need to be changed, and the scope of modifications can be reduced.

[0057] In this embodiment, the setting information includes information indicating whether or not a setting item is displayed and whether or not the setting item can be changed. According to this embodiment, when a function is switched between enabled and disabled or a function is added due to a change in the specifications of the work machine, it is sufficient to change the setting information, which is the master data stored in the first controller 20. This embodiment can easily accommodate changes in the specifications of the work machine.

[0058] This embodiment allows for automatic setting and display based on combinations of setting values ​​for multiple setting items, according to feasibility setting conditions.

[0059] In this embodiment, the first controller 20, which undergoes more software updates than the second controller 40, stores the setting information, which is the master data. According to this embodiment, the frequency of updates to the second controller 40, which implements the basic functions of the work machine, can be reduced.

[0060] In this embodiment, the settings include controls for stopping the work machine, igniting an external buzzer, and igniting a cab buzzer when an obstacle is detected by the surrounding monitoring device 10. According to this embodiment, the settings screen for various functions of the surrounding monitoring device 10 can be displayed appropriately.

[0061] <Variation> Figure 13 is a schematic diagram of a modified display system. Figure 14 is a functional block diagram showing a modified first controller. The display system 1 includes a first controller 20, a second controller 40, and a third controller 60 that manages the specifications of the second controller 40. The third controller 60 has a function corresponding to the setting information generation unit 22 of the first controller 20. The third controller 60 transmits the generated setting information to the first controller 20. The first controller 20 receives the setting information from the third controller 60 via the first interface unit 26 by the first setting information receiving control unit 27. The first controller 20 transmits the setting information to the second controller 40 via the second interface unit 21 by the second setting information transmission control unit 24. With this configuration, the third controller 60 manages the specifications of the second controller 40, so when the specifications change, only the third controller 60 needs to be modified, and the scope of modification can be limited.
