[0004] In information display devices such as Patent Documents 1 and 2 above, for example, it is required to make it easy for an operator to check necessary information by displaying it on the display surface without overlapping a plurality of display images. Also, for example, it is required to improve the operability in switching the displayed information by making it possible to switch the displayed information by an operation on the display surface.

[0005] An object of the present invention is to make it easy for an operator to check necessary information on the display surface and improve the operability in switching the displayed information. [Means for solving the problem]

[0006] The information display device according to this embodiment is mounted on a construction machine in which a slewing body can rotate relative to a traveling vehicle body. The information display device comprises a display device and a display control unit. The display device has a display surface capable of displaying information in a display configuration in which a main display area and a first sub-display area are separated from each other, and is located in the driver's cab of the slewing body. In the display configuration, the display control unit displays one of a plurality of main information items in the main display area and one of a plurality of first sub-information items in the first sub-display area as information related to the construction machine. The display control unit also switches the display in the main display area among the plurality of main information items and switches the display in the first sub-display area among the plurality of first sub-information items in response to a swipe operation being input in the main display area.

[0009] In this embodiment, a crane 1 is provided as a construction machine. Figure 1 shows a crane 1 according to this embodiment. As shown in Figure 1, the crane 1 comprises a traveling body 2 and a slewing body 3. The slewing body 3 is connected to the traveling body 2 from the vertically upper side (arrow Z1 side). The slewing body 3 is also rotatable relative to the traveling body 2 about a slewing axis P that is in the vertical direction (direction shown by arrows Z1 and Z2). The slewing body 3 comprises a cab (operator's room) 5 and a boom support base 6.

[0010] In the slewing body 3, including the boom support base 6, a longitudinal direction (indicated by arrows X1 and X2) is defined that intersects (orthogonal or nearly orthogonal to) the vertical direction. In addition, the slewing body 3, including the boom support base 6, has a width direction (indicated that is orthogonal or nearly orthogonal to the plane of the paper in Figure 1) that intersects (orthogonal or nearly orthogonal to) both the vertical and longitudinal directions. Similarly, the traveling vehicle body 2 also has a longitudinal direction that intersects (orthogonal or nearly orthogonal to) the vertical direction, and a width direction that intersects (orthogonal or nearly orthogonal to) both the vertical and longitudinal directions. Figure 1 shows a state where the longitudinal direction of the traveling vehicle body 2 coincides with or nearly coincides with the longitudinal direction of the slewing body 3, and the width direction of the traveling vehicle body 2 coincides with or nearly coincides with the width direction of the slewing body 3. Also in Figure 1, the crane 1 is shown with the front side of the traveling vehicle body 2 coinciding with or nearly coincides with the front side of the slewing body 3 (arrow X1 side).

[0011] The cab 5 receives input for operations related to the crane 1, such as operating the vehicle body 2, rotating the slewing body 3, raising and lowering the boom 7, and operating each of the two pairs of outriggers 9. In this embodiment, the cab 5 is provided on the slewing body 3, but the vehicle body 2 does not have a driver's cab. The cab 5 is an example of a driver's cab.

[0012] The crane 1 also includes a boom 7 and a boom luffing cylinder 8. The boom 7 extends longitudinally from its rear end to its front end, and the rear end of the boom 7 is attached to the boom support base 6 of the slewing body 3. The boom 7 is luffable and can swivel together with the slewing body 3 relative to the vehicle body 2. In the example shown in Figure 1, the cab 5 is positioned on one side in the width direction relative to the boom 7 in the slewing body 3. One end of the boom luffing cylinder 8 is connected to the boom support base 6 of the slewing body 3, and the other end is connected to the boom 7. By driving the boom luffing cylinder 8, that is, by extending or retracting the boom luffing cylinder 8, the boom 7 performs luffing operations.

[0013] On the vehicle body 2, for example, two pairs of outriggers 9 are attached. On the vehicle body 2, one pair of outriggers 9 is positioned at the front end, and another pair of outriggers 9 is positioned at the rear end. The pair of outriggers 9 at the front end are positioned in front of each of the wheels and the pivot axis P of the slewing body 3. The pair of outriggers 9 at the rear end are positioned behind each of the wheels and the pivot axis P of the slewing body 3. When the vehicle body 2 is stopped and work is performed using the crane 1, each of the two pairs of outriggers 9 is extended outwards in the width direction of the vehicle body 2, and each of the two pairs of outriggers 9 is brought into contact with the ground.

[0014] FIG. 2 is a block diagram showing the configuration of the control system of a construction machine. A crane 1, which is an example of a construction machine, includes a camera 10, an information display device 20, an operation switch 31, and an operation lever 32. The information display device 20 includes a touch panel 21, a processor 25, and a storage device 26. The touch panel 21, the operation switch 31, and the operation lever 32 are provided inside the cab 5. The processor 25 and the storage device 26 are provided at an arbitrary position of the construction machine.

[0015] The camera 10 images the area around the construction machine. At least one or more cameras 10 are provided at an arbitrary position of the construction machine. The camera 10 is provided, for example, behind the traveling vehicle body 2 and images the area behind the traveling vehicle body 2. Note that the present invention is not limited to this, and the camera 10 may be provided, for example, on the right side of the traveling vehicle body 2 with respect to the traveling direction and image the area on the right side of the traveling direction. The camera 10 outputs the captured image to the processor 25.

[0016] The touch panel 21 includes a display surface p and a touch sensor 23. The touch panel 21 is a liquid crystal display device or the like that displays information about the construction machine or the like on the display surface p. In other words, the touch panel 21 displays a display image representing information about the construction machine or the like on the display surface p. The touch sensor 23 detects a swipe operation of an operator input to the display surface p.

[0017] The information about the construction machine includes a plurality of main information, a plurality of first sub-information, and a plurality of second sub-information. Each of the plurality of main information, each of the plurality of first sub-information, and each of the plurality of second sub-information are different from each other.

[0018] The touch panel 21 can display information about the construction machine in a display mode in which a plurality of display areas are partitioned from each other. The touch panel 21 displays main information in the main display area R1, first sub-information in the first sub-display area R2, and second sub-information in the second sub-display area R3, for example, when the traveling vehicle body 2 is stopped.

[0019] The touch panel 21 displays one of several main pieces of information in the main display area R1. Figure 3 is a diagram illustrating the relationships between the information related to the construction machinery. As shown in Figure 3, the multiple pieces of information include, for example, main information a, main information d, and main information f. The display images representing main information a, d, and f are called main images A, D, and F. Main information a is, for example, parameters such as the dimensions and angles of each component of the construction machinery, and is used when performing tasks such as rotating the boom 7. The touch panel 21 displays, for example, main image A in the main display area R1. Main information d is, for example, information for making various settings such as attaching a jig to the tip of the boom 7, and is used before performing the above tasks. The touch panel 21 may also display, for example, main image D in the main display area R1. Main information f includes, for example, a performance table for each component of the crane 1, a tutorial on the operation of the crane 1, the communication status of the construction machinery, and information for performing various processes such as creating a PDF. This information is checked by the operator when the crane 1 is not operating. The touch panel 21 may display main image F from among multiple main images in the main display area R1.

[0020] The touch panel 21 displays one of the multiple first sub-informations in the first sub-display area R2. As shown in Figure 3, the multiple first sub-informations include, for example, first sub-informations b1 to b4, first sub-informations e1 to e3, and first sub-informations g1 to g3. The display images representing each of the first sub-informations b1 to b4, first sub-informations e1 to e3, and first sub-informations g1 to g3 are called first sub-images B1 to B4, first sub-images E1 to E3, and first sub-images G1 to G3. First sub-information b1 includes, for example, two captured images: an image acquired from a camera 10 positioned on the side of the vehicle body 2 and an image acquired from a camera 10 positioned behind the vehicle body 2. The touch panel 21 displays, for example, a first sub-image B1 in the first sub-display area R2, which displays the two captured images side by side vertically. The multiple primary sub-informations also include, for example, information regarding the settings of camera 10, information regarding limitations on various components of the construction machinery, and information regarding the settings of targets for generating the buzzer.

[0021] Next, we will explain the relationship between the main information and the first sub-information. Multiple first sub-informations are divided into multiple information groups. That is, each of the multiple first sub-informations is included in one of the information groups. Each of the information groups consists of some of the first sub-informations from the multiple first sub-informations. Typically, each of the information groups consists of two or more first sub-informations from the multiple first sub-informations. Specifically, for example, among the multiple first sub-informations, first sub-information b1 is included in information group b. Also, among the multiple first sub-informations, first sub-informations b2 to b4 are also included in information group b. Furthermore, first sub-informations e1 to e3 are included in information group e, and first sub-informations g1 to g3 are included in information group g. Note that each of the information groups may consist of one first sub-information from the multiple first sub-informations.

[0022] One of the multiple main pieces of information corresponds one-to-one with one of the multiple information groups. For example, main piece of information a corresponds one-to-one with information group b. Main piece of information d corresponds one-to-one with information group e, and main piece of information f corresponds one-to-one with information group g. When the touch panel 21 displays one piece of main piece of information in the main display area R1, it displays one of the one or more first sub-pieces of information included in the information group corresponding to that main piece of information in the first sub-display area R2.

[0023] The touch panel 21 displays one of the multiple second sub-informations in the second sub-display area R3. The multiple second sub-informations include, for example, second sub-informations c1 to c5. The display images representing each of the second sub-informations c1 to c5 are referred to as second sub-images C1 to C5. The second sub-informations include information such as the amperage meter, odometer, detection results of people around the construction machine, the speed of the moving vehicle 2, and temperature.

[0024] The touch sensor 23 detects the operator's swipe operation applied to the display surface p. The touch sensor 23 generates different detection signals depending on the display area where the detected swipe operation was applied and the direction in which the swipe operation was applied, and outputs the generated detection signals to the processor 25.

[0025] The processor 25 is an integrated circuit or circuit configuration that includes a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate Array), etc. There may be only one processor 25 or multiple processors 25. Processing by the processor 25 is performed according to a program stored in the processor 25 or the storage device 26. The processor 25 acquires the captured image captured by the camera 10. The processor 25 also has a display control function 251. The display control function 251 enables the processor 25 to display various information on the touch panel 21. The display control function 251 is an example of a display control unit.

[0026] The processor 25 switches the information displayed on the display surface p in response to the input swipe operation. In other words, the processor 25 switches the information displayed on the display surface p based on the detection signal output from the touch sensor 23. In the following description, the phrase "switching information" includes "switching the display image representing information to another display image representing other information."

[0027] The storage device 26 stores processing programs used by the processor 25, as well as parameters, functions, tables, etc., used in calculations performed by the processor 25.

[0028] Next, an example of the operation of the information display device 20 configured as described above will be explained with reference to Figures 4 to 7. Figure 4 is a flowchart illustrating an example of the operation of the information display device 20 according to the embodiment. Figure 5 is a diagram illustrating the display surface p before and after detection of a swipe operation in the main display area R1 according to the embodiment. Figure 6 is a diagram illustrating the display surface p before and after detection of a swipe operation in the first sub-display area R1 according to the embodiment. Figure 7 is a diagram illustrating the display surface p before and after detection of a swipe operation in the second sub-display area R1 according to the embodiment. In Figure 5, the display image representing the entire display area of ​​the display surface p is denoted as display image I1 or display image I2. Also, in Figure 6, the display image representing the entire display area of ​​the display surface p is denoted as display image I3 or display image I4. Also, in Figure 6, the display image representing the entire display area of ​​the display surface p is denoted as display image I5 or display image I6.

[0029] Initially, with the power of the information display device 20 turned ON and each of the two pairs of outriggers 9 in contact with the ground, the processor 25 displays one of the multiple main information items in the main display area R1. At the same time, it displays one of the multiple first sub-information items in the first sub-display area R2, and one of the multiple second sub-information items in the first sub-display area R3. The first sub-information item displayed together with the main information item displayed in the main display area R1 is one of one or more first sub-information items included in the information group corresponding to that main information item. As shown in Figures 5 to 7, the first sub-display area R2 corresponds to, for example, the area around the lower left corner of the display surface p. The second sub-display area R3 corresponds to, for example, the area around the lower right corner of the display surface p. The main display area R1 corresponds to the remaining area of ​​the entire display surface p, excluding the first sub-display area R2 and the second sub-display area R3. In this state, step ST10 is started.

[0030] In step ST10 in Figure 4, if the touch sensor 23 detects a swipe operation in the main display area R1, the process proceeds to step ST11. On the other hand, if the touch sensor 23 does not detect a swipe operation in the main display area R1, the process proceeds to step ST20.

[0031] After step ST10, in step ST11, the touch sensor 23 detects the direction of the swipe operation input to the main display area R1. The touch sensor 23 generates a detection signal corresponding to the display area to which the detected swipe operation was input and the input direction, and outputs the generated detection signal to the processor 25.

[0032] The processor 25 receives a detection signal output from the touch sensor 23. Then, in step ST12, the processor 25 associates the main information displayed in the main display area R1 with the first sub-information that was displayed together with the main information in the first sub-display area R2 and stores it in the storage device 26. Specifically, for example, before the input of a swipe operation, the processor 25 displays a main image A representing the main information a in the main display area R1 and a first sub-image B1 representing the first sub-information b1 in the first sub-display area R2, as shown in the display image I1 in Figure 5. In this case, the processor 25 associates the main information a with the first sub-information b1 that was displayed together with the main information a in the first sub-display area R2 and stores it in the storage device 26. Note that when the power of the information display device 20 is turned OFF, the processor 25 may erase the main information a and the first sub-information b1 stored in the storage device 26.

[0033] In step ST13, the processor 25 acquires the main information of the switching destination based on the detection signal output from the touch sensor 23. The processor 25 acquires the main information corresponding to the direction in which the swipe operation was input. The input direction of the swipe operation will be described later. Then, the processor 25 acquires the first sub-information that was displayed in the first sub-display area R2 when the acquired main information was previously displayed. Specifically, for example, the processor 25 acquires the main information d of the switching destination based on the detection signal output from the touch sensor 23. Then, the processor 25 reads the first sub-information e1, which was stored in association with the main information d, from the storage device 26. Note that under a setting where the first sub-information is erased when the power is turned off, there are cases where the main information is displayed, the power is turned off without displaying that main information again, and the main information is displayed again when the power is turned on. In this case, the processor 25 erases the main information and the first sub-information b1 stored in the storage device 26. Therefore, the processor 25 does not retrieve the first sub-information that was displayed in the first sub-display area R2 when the main information was last displayed from the storage device 26, but instead retrieves any predetermined first sub-information.

[0034] In step ST14, the processor 25 switches the display in the main display area R1 between multiple main information items in response to a swipe operation being input in the main display area R1. At the same time, the processor 25 switches the display in the first sub-display area R2 between multiple first sub-information items. The first sub-information item displayed in the first sub-display area R2 after the switch is one of one or more first sub-information items included in the information group corresponding to the main information item to be displayed after the switch. Specifically, as shown by arrow y1 and display image I2 in Figure 5, the processor 25 displays the main image D representing the main information d acquired in ST13 in the main display area R1. At the same time, the processor 25 displays the first sub-image E1 representing the first sub-information e1 acquired in ST13 in the first sub-display area R2. Meanwhile, as shown by display images I1 and I2 in Figure 5, the processor 25 maintains the display of the second sub-image C1 in the second sub-display area R3. After step ST14, the process returns to step ST10.

[0035] Next, after step ST10, if the touch sensor 23 detects a swipe operation in the first sub-display area R2 in step ST20, the process proceeds to step ST21. On the other hand, if the touch sensor 23 does not detect a swipe operation in the first sub-display area R2, the process proceeds to step ST30.

[0036] After step ST20, in step ST21, the touch sensor 23 detects the direction of the swipe operation input to the first sub-display area R2. The touch sensor 23 generates a detection signal corresponding to the display area to which the detected swipe operation was input and the input direction, and outputs the generated detection signal to the processor 25.

[0037] In step ST22, even if a swipe operation is input in the first sub-display area R2, the processor 25 does not switch the main information currently displayed in the main display area R1, but maintains that display. On the other hand, in response to the swipe operation being input in the first sub-display area R2, the processor 25 switches the display in the first sub-display area R2 between two or more first sub-information items included in the information group corresponding to the main information currently displayed in the main display area R1. Specifically, for example, suppose the touch panel 21 is displaying a main image D representing main information d in the main display area R1, as shown in display image I3 in Figure 6. At the same time, suppose the touch panel 21 is displaying a first sub-image E1 representing first sub-information e1 in the first sub-display area R2, and a first sub-image C1 representing second sub-information c1 in the second sub-display area R2. In this state, even if a swipe operation is input in the first sub-display area R2, the display of the main image D and the second sub-image C1 is maintained, as shown in the display images I3 and I4 in Figure 6. On the other hand, as shown by arrow y2 and display image I4 in Figure 6, the processor 25 switches the display in the first sub-display area R2 to the sub-display image E2 representing the first sub-information e2, in response to the input of a swipe operation in the first sub-display area R2. After step ST22, the process returns to step ST10. Note that if there is only one first sub-display information included in the information group corresponding to the main image, the processor 25 does not switch the display even if a swipe operation is input in the first sub-display area R2.

[0038] Furthermore, if the touch sensor 23 detects a swipe operation in the second sub-display area R3 in step ST30, after step ST20, the process proceeds to step ST31. On the other hand, if the touch sensor 23 does not detect a swipe operation in the second sub-display area R3, the process returns to step ST10.

[0039] After step ST30, in step ST31, the touch sensor 23 detects the direction of the swipe operation input to the second sub-display area R3. The touch sensor 23 generates a detection signal corresponding to the display area to which the detected swipe operation was input and the input direction, and outputs the generated detection signal to the processor 25.

[0040] In step ST32, the processor 25 maintains the display of the main display area R1 and the first sub-display area R2 even when a swipe operation is input in the second sub-display area R3. On the other hand, the processor 25 switches the display in the second sub-display area R3 among multiple second sub-informations in response to the input of a swipe operation in the second sub-display area R3. Specifically, for example, suppose the touch panel 21 is displaying a main image D representing main information d in the main display area R1, as shown in display image I5 in Figure 7. At the same time, suppose the touch panel 21 is displaying a first sub-image B1 representing first sub-information b1 in the first sub-display area R2, and a first sub-image C1 representing second sub-information c1 in the second sub-display area R2. In this state, even when a swipe operation is input in the second sub-display area R3, the display of the main image D and the first sub-image B1 is maintained, as shown in display images I5 and I6 in Figure 7. On the other hand, as shown by arrow y3 and display image I6 in Figure 6, the processor 25, in response to a swipe operation being input in the second sub-display area R3, switches the display in the second sub-display area R3 to the sub-display image C2 representing the second sub-information c2. After step ST32, the process returns to step ST10.

[0041] The information display device 20 repeatedly performs the above-described process, for example, until the power is turned off.

[0042] Next, the switching of display images according to the direction of the detected swipe operation will be described. The processor 25, in response to the input of a swipe operation, switches the currently displayed display image to a display image according to the direction of the input swipe operation. Figure 8 is a diagram illustrating the switching of display images according to the input direction of a swipe operation according to the embodiment. In Figure 8, the display images representing the first sub-display area R2 are displayed images I7 to I9. The touch sensor 23 can detect a swipe operation directed to the right relative to the display surface p, for example, as shown by arrow r1 in display image I7 in Figure 8. The touch sensor 23 can also detect a swipe operation directed to the left relative to the display surface p, for example, as shown by arrow l1 in display image I7 in Figure 8. The touch sensor 23 can detect a swipe operation directed to the right or to the left, for example.

[0043] The processor 25 responds to a rightward swipe input in the first sub-display area R2 by switching the display in the first sub-display area R2 to the first sub-image corresponding to the rightward swipe operation. On the other hand, the processor 25 responds to a leftward swipe input in the first sub-display area R2 by switching the display in the first sub-display area R2 to the first sub-image corresponding to the leftward swipe operation. Similarly, for the main image or the second sub-image, the processor 25 switches to the other first sub-image or other second sub-image depending on the direction of the swipe operation. Specifically, for example, as shown by arrow y4 and display images I7 and I8 in Figure 8, the processor 25 responds to a rightward swipe input in the first sub-display area R2 by switching from sub-display image E1 representing the first sub-information e1 to sub-display image E2 representing the first sub-information e2. Then, while the first sub-image E2 is being displayed, the processor 25, in response to a rightward swipe operation being input in the first sub-display area R2, switches the display of the first sub-display area R2 from the first sub-image E2 to the first sub-image E3, as shown by arrow y5, display images I8 and I9 in Figure 8. On the other hand, as shown by arrow y6, display images I7 and I9 in Figure 8, the processor 25, in response to a leftward swipe operation being input in the first sub-display area R2, switches the display of the first sub-display area R2 from the first sub-image E3 to the first sub-display image E3, as shown by arrow y6 in Figure 8. Furthermore, while the first sub-image E3 is being displayed, the processor 25, in response to a leftward swipe operation being input in the first sub-display area R2, switches the display of the first sub-display area R2 from the first sub-image E3 to the first sub-image E2, as shown by arrow y6 in Figure 8. Furthermore, while the first sub-image E1 is being displayed, the processor 25, in response to a rightward swipe input in the first sub-display area R2 followed by a leftward swipe input, switches the display in the first sub-display area R2 from the first sub-image E1 to E2, then E1.

[0044] The processor 25, in response to the fact that rightward swipe operations have been input by a reference number of times more than leftward swipe operations in the first sub-display area R2, displays the same first sub-information that was displayed before the reference number of swipe operations were input in the first sub-display area R2. The reference number corresponds, for example, to the number of types of display images that represent each of the two or more first sub-information contained in one information group. As shown in the display image I7 in Figure 8, the first sub-image E1 representing the first sub-information e1 is displayed in the first sub-display area R2. The information group e containing the first sub-information e1 consists of three first sub-informations e1 to e3. Therefore, the reference number in this example is 3. In this state, the touch sensor 23 detects three consecutive rightward swipe operations in the first sub-display area R2, and does not detect any leftward swipe operations in the first sub-display area R2 during this time. In this case, rightward swipes are input by a criterion number (3 - 0 = 3) more than leftward swipes. At this time, the processor 25 switches the display of the first sub-image E1 representing the first sub-information e1 in the order of first sub-images E2, E3, and E1, corresponding to the fact that three consecutive rightward swipes have been input in the first sub-display area R2. As a result, the processor 25 displays the same first sub-information E1 in the first sub-display area R2 as the first sub-information E1 that was displayed before the swipe operations were input by the criterion number of times. Alternatively, for example, suppose that in the first sub-display area R2, swipe operations are input consecutively in the order of rightward, rightward, leftward, rightward, and rightward. In this case, rightward swipes are input by a criterion number (4 - 1 = 3) more than leftward swipes. At this time, the processor 25, in response to the continuous input of swipe operations in the order described above, switches the display of the first sub-image E1 representing the first sub-information e1 in the order of first sub-images E2, E3, E2, E3, E1. As a result, the processor 25 displays the same first sub-information in the first sub-display area R2 as the first sub-information that was displayed before the swipe operation was input a certain number of times more.

[0045] Note that the rightward swipe is an example of the first orientation, and the leftward swipe is an example of the second orientation. The processor 25 may, in response to the fact that leftward swipe operations have been input by a reference number of times more than rightward swipe operations, display the same first sub-information that was displayed before the reference number of swipe operations was input in the first sub-display area R2. In addition, the processor 25 may, in response to the fact that swipe operations of the first orientation have been input by a reference number more than swipe operations of the second orientation, display the same second sub-information that was displayed before the reference number of swipe operations was input in the second sub-display area R3. In this case, the reference number corresponds to the number of types of display images that represent each of the second sub-information. Similarly, the processor 25 may, in response to the fact that a criterion number of swipe operations in the first orientation have been input in the main display area R1 compared to the number of swipe operations in the second orientation, display the same main information in the main display area R1 as the main information that was displayed before the criterion number of swipe operations were input. In this case, the criterion number corresponds to the number of types of display images that represent each of the main information.

[0046] As described above, the information display device 20 according to the embodiment has a touch panel 21 (display device) capable of displaying information in a display mode in which the main display area R1 and the first sub-display area R2 are separated from each other. The processor 25, through the implementation of the display control function 251 (display control unit), displays one of the multiple main information items in the main display area R1 and one of the multiple first sub-information items in the first sub-display area R2 as information related to the construction machine in the above display mode. At the same time, the processor 25 switches the display in the main display area R1 among the multiple main information items and switches the display in the first sub-display area R2 among the multiple first sub-information items in response to a swipe operation input in the main display area R1. This makes it easier for the operator to confirm the information they need. In addition, since the information displayed on the display surface p can be switched using a highly operable swipe operation as a trigger, the operability of switching the displayed information can be improved. Therefore, it is possible to make it easier for the operator to confirm the information they need and to improve the operability of switching the displayed information. This makes it possible to improve work efficiency during construction machine operation.

[0047] Furthermore, according to the embodiment, the multiple first sub-informations are divided into multiple information groups. Each of the multiple information groups consists of one or more first sub-informations from the multiple first sub-informations and corresponds one-to-one with one of the multiple main informations. In response to a swipe operation being input in the main display area R1, the processor 25 switches the display in the first sub-display area R2 from one of the one or more first sub-informations included in the information group corresponding to the main information that was displayed before the swipe operation to one of the one or more first sub-informations included in the information group corresponding to the main information to be displayed after the swipe operation. With this configuration, one or more first sub-informations related to the main information are divided into one or more first sub-informations such that they are included in the information group related to the main information. Therefore, the processor 25 can display the first sub-informations related to the main information after the switch, along with the main information after the switch.

[0048] Furthermore, according to the embodiment, the processor 25, in response to a swipe operation being input in the main display area R1, switches the display of the first sub-display area R2 to the first sub-information that was displayed in the first sub-display area R2 when the main information to be displayed after the swipe operation was previously displayed in the main display area R1. With this configuration, the first sub-information that was displayed together with the main information to be displayed after the swipe operation when the main information to be displayed after the swipe operation was previously displayed in the main display area R1 can also be confirmed by the operator at the same time.

[0049] Furthermore, according to the embodiment, the processor 25 maintains the display of the main information in the main display area R1 in response to a swipe operation being input in the first sub-display area R2. The processor 25 switches the display in the first sub-display area R2 between two or more first sub-information items included in the information group corresponding to the main information currently displayed in the main display area R1. With this configuration, while one main piece of information is being displayed, other first sub-information items related to that main piece of information can be switched without switching that main piece of information. Therefore, it becomes easier for the operator to confirm the information they need.

[0050] Furthermore, according to the embodiment, the processor 25, in response to the fact that a certain number of right (first orientation) swipe operations have been input more times than left (second orientation) swipe operations in the first sub-display area, displays the same first sub-information that was displayed before the certain number of swipe operations were input in the first sub-display area. With this configuration, the processor 25 enables rotational display of the first sub-information. As a result, the processor 25 can allow the operator to confirm the information they want to confirm in fewer steps. Specifically, for example, suppose there are many first sub-information items in a group of information, and the certain number of swipe operations is 3 or more, and the operator inputs a number of swipe operations in the first orientation consecutively equal to the certain number of swipe operations minus 1. In this case, without this configuration, the operator would need to perform the swipe operation again a number of times equal to the certain number of swipe operations minus 1 in order to confirm the information that was displayed before the swipe operation. On the other hand, since the information display device 20 has the above configuration, by performing a swipe operation in the first direction just once, the information that was displayed before the swipe operation can be confirmed. In this way, the worker's work efficiency can be further improved.

[0051] Furthermore, according to the embodiment, in the above display configuration, the display surface p is divided into a second sub-display area R3 in addition to the main display area R1 and the first sub-display area R2. The processor 25 displays one of the multiple second sub-information items in the second sub-display area R3 as information related to the construction machine, and maintains the display in the second sub-display area R3 even if a swipe operation is input in a display area other than the second sub-display area R3. With this configuration, even if a swipe operation is performed in the main display area R1 and the first sub-display area R2, the display in the third display area R3 can be maintained, so that more information necessary for the operator can be displayed.

[0052] Furthermore, according to this embodiment, the construction machine comprises an information display device 20, a slewing body 3, and a traveling vehicle body 2. The slewing body 3 includes a cab 5 (driver's room) on which the touch panel 21 of the information display device 20 is located. The slewing body 3 is rotatably connected to the traveling vehicle body 2. With this configuration, it is possible to provide a construction machine equipped with an information display device 20 that makes it easier for workers to check necessary information and improves operability in switching between displayed information.

[0053] (modified version) In this embodiment, the touch sensor 23 detects a swipe operation, generates a detection signal, and outputs the detection signal to the processor 25, but the system is not limited to this configuration. For example, in the event of a malfunction in the touch sensor 23, an input instruction may be input to the operation switch 31 as an emergency measure, and the input instruction may be output to the processor 25. Also, in the event of a malfunction in the touch sensor 23, an input instruction may be input to the operation lever 32, not just the operation switch 31, and the input instruction may be output to the processor 25. The processor 25 may then switch the displayed image based on the input instruction output from the operation switch 31 or the operation lever 32, instead of the detection signal output from the touch sensor 23.

[0054] Furthermore, in this embodiment, when the vehicle body 2 is stopped with each of the two pairs of outriggers 9 grounded, the touch panel 21 can display information in a manner in which the main display area R1, the first sub-display area R2, and the second sub-display area R3 are separated from each other. However, the touch panel 21 may, for example, display information about the construction machinery on the display surface p in a display manner different from the above when each of the two pairs of outriggers 9 is activated. Figure 9 is a diagram illustrating the display surface p when the outriggers 9 are activated according to this embodiment. In Figure 9, the display image representing the entire display area of ​​the display surface p is referred to as display image I10 or display image I11. The processor 25 switches from the display manner when the vehicle body 2 is stopped to the display manner when the outriggers 9 are activated, as shown by arrow y6, display images I10 and I11, etc. in Figure 9, in response to input such as an operation to activate each of the two pairs of outriggers 9.

[0055] As shown in display image I11, the touch panel 21 can display information in a manner in which the two display areas, the main display area R1 and the first sub-display area R2, are combined into a single display area R4, and the second sub-display area R3 is separated from each other. Hereafter, the combined display area R4 will be referred to as the combined display area R4. In the combined display area R4, the touch panel 21 displays an outrigger image H that shows information related to the operation of the outriggers included in the information related to the construction machinery, and in the second sub-display area R3, it displays second sub-information such as the second sub-information C1.

[0056] Furthermore, the processor 25 may, for example, switch the display on the display surface p in response to an operation in the cab 5 where the gear is changed from neutral to D range. The touch panel 21 also displays information about the construction machinery on the display surface p in a display mode in which the combined display area R4 and the second sub-display area R3 are separated from each other, even when the vehicle body 2 is in motion. At this time, the touch panel 21 displays, for example, an image captured by the camera 10 in the combined display area R4, and displays second sub-information in the second sub-display area R3. Typically, when the vehicle is in motion, the processor 25 is set not to switch the display on the display surface p even if a swipe operation is input. However, it is not limited to this, and the display on the display surface p may be switched in response to a swipe operation even when the vehicle is in motion.

[0057] Furthermore, although the embodiment has described an example in which the cab 5 is provided on the slewing body 3 and there is no driver's cab on the vehicle body 2, it is not limited to this configuration. The slewing body 3 may be provided with a cab 5, and the vehicle body 2 may also be provided with a driver's cab (not shown). In this configuration, the touch panel 21 is provided inside the cab 5, and another touch panel (not shown) is also provided inside the driver's cab of the vehicle body 2. The other touch panel in this modified example displays the captured image taken by the camera 10 while the vehicle body 2 is in motion. On the other hand, the touch panel 21 in the cab 5 of the slewing body 3 does not have to display the captured image taken by the camera 10 while the vehicle body 2 is in motion.

[0058] Furthermore, the present invention is not limited to the embodiments described above, and can be modified in various ways during implementation without departing from its essence. Also, each embodiment may be combined as appropriately as possible, in which case the combined effects can be obtained. Moreover, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriate combinations of the multiple disclosed constituent elements.
