[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example of the present invention, and is not intended to limit the technical scope of the present invention.

[0014] (Embodiment 1) [1] Overall structure As shown in Figs. 1 and 2, a work machine display control system 1 according to this embodiment (hereinafter simply referred to as "display control system 1") is used to display information related to a work machine 3 such as a backhoe. The display control system 1 controls the display device 2 to cause the display device 2 to display a display screen D1 (see Fig. 2). In this embodiment, as an example, the display device 2 is mounted on the body 30 of the work machine 3, and presents various pieces of information on the display screen D1 to a user (operator) who operates the work machine 3. In other words, the user who operates the work machine 3 can visually obtain various pieces of information related to the work machine 3 by looking at the display screen D1 displayed on the display device 2.

[0015] In this embodiment, as shown in Fig. 1, the display control system 1, together with the display device 2, constitutes a work machine display system 10 (hereinafter simply referred to as "display system 10"). In other words, the display system 10 according to this embodiment comprises the display control system 1 and a display device 2 that displays a display screen D1. Also, in this embodiment, the display system 10, together with the machine body 30, constitutes the work machine 3. In other words, the work machine 3 according to this embodiment comprises the display system 10 and the machine body 30 on which the display device 2 is mounted.

[0016] Here, the display system 10 and the machine 30 are capable of communicating with each other. In the present disclosure, "capable of communication" means that information (data) can be exchanged directly or indirectly via a communication network or a repeater, etc., by an appropriate communication method such as wired communication or wireless communication (communication using radio waves or light as a medium). The display system 10 and the machine 30 can communicate with each other, for example, by a communication method such as CAN (Controller Area Network). The communication means between the display system 10 and the machine 30 is not limited to the above example, and can be realized by an appropriate communication means. In addition, it is not an essential configuration of the display control system 1 that the display system 10 and the machine 30 can communicate with each other.

[0017] In a work machine 3 equipped with such a display system 10, for example, a hydraulic pump is driven by an engine 37 (see FIG. 1), and hydraulic oil is supplied from the hydraulic pump to hydraulic actuators (including hydraulic cylinders, hydraulic motors, etc.) of various parts of the machine body 30, thereby driving the machine body 30. Such a work machine 3 is controlled, for example, by a user (operator) aboard the driver's cab of the machine body 30 operating an operating lever or the like.

[0018] Here, a display device 2 is mounted in the cab of the machine body 30, and the user operates the work machine 3 while viewing various information related to the work machine 3 displayed on the display device 2. As an example, information related to the operating state of the work machine 3, such as the cooling water temperature and hydraulic oil temperature, is displayed on the display screen D1 of the display device 2, allowing the user to check information related to the operating state of the work machine 3 required for operating the work machine 3 on the display device 2. Furthermore, if a camera 36 is provided on the machine body 30 of the work machine 3, an image of the surroundings of the work machine 3 captured by the camera 36 can also be displayed on the display screen D1 of the display device 2. This allows the user to check, for example, the situation behind the work machine 3, which is likely to be a blind spot from the driver's seat, from the surrounding image displayed on the display device 2 when operating the work machine 3.

[0019] The display control system 1 according to this embodiment realizes a configuration that makes it easy to improve the visibility of each of the various pieces of information related to the work machine 3. This reduces the burden on the user operating the work machine 3 to grasp the various pieces of information related to the work machine 3, for example, and leads to improved operability of the work machine 3, and is therefore expected to improve the efficiency of work using the work machine 3.

[0020] [2] Definition In the present disclosure, the term "work machine" refers to various types of work machines, and examples thereof include work vehicles such as backhoes (including hydraulic excavators, mini excavators, etc.), wheel loaders, and carriers. The work machine 3 is not limited to a "vehicle" and may be, for example, a work vessel, a work flying object such as a drone or a multicopter, etc. Furthermore, the work machine 3 is not limited to a construction machine (construction machinery), and may be, for example, an agricultural machine (farm machinery) such as a rice transplanter, a tractor, or a combine harvester. In this embodiment, unless otherwise specified, an example will be described in which the work machine 3 is a riding type backhoe that can perform excavation work, ground leveling work, trench digging work, loading work, etc. as work.

[0021] In the present disclosure, a "screen" such as the display screen D1 means a video (image) displayed on the display device 2, and includes icons, figures, photographs, text, video, and the like. That is, the display control system 1 is capable of causing the display device 2 to display the display screen D1 including icons and the like showing information relating to the operating state of the work machine 3, such as the cooling water temperature and hydraulic oil temperature. Here, when the display screen D1 includes a video, and the like, the display screen D1 does not include a fixed image, but includes an image that changes from moment to moment.

[0022] [3] Aircraft Next, the configuration of the machine body 30 of the work machine 3 will be described with reference to Fig. 1. The work machine 3 is equipped with a working section 31, a rotating section 32, and a traveling section 33 in the machine body 30. In this embodiment, the machine body 30 further includes a cooling water temperature sensor 34, a hydraulic oil temperature sensor 35, a camera 36, ​​an engine 37, etc.

[0023] The working unit 31 is supported by the swivel unit 32 and performs work. The swivel unit 32 is located above the travel unit 33 and is configured to be rotatable around a rotation axis along the vertical direction relative to the travel unit 33. The travel unit 33 is configured to be capable of traveling (including rotating) on ​​the ground. In this embodiment, since it is assumed that the work machine 3 is a riding type backhoe as described above, the working unit 31 is driven according to the operation of a user (operator) seated in the cab and performs work such as excavation work. The cab (e.g., a cabin) in which the user (operator) sits is provided on the swivel unit 32.

[0024] The working unit 31 has a boom, an arm, a bucket, and hydraulic actuators (including hydraulic cylinders, hydraulic motors, etc.). Here, the working unit 31 operates by receiving power from an engine 37 serving as a power source. Specifically, a hydraulic pump is driven by the engine 37, and hydraulic oil is supplied from the hydraulic pump to the hydraulic actuators of the working unit 31, thereby operating the working unit 31.

[0025] The swivel unit 32 has a hydraulic motor (hydraulic actuator) for swivel and the like. In addition to a driver's cab, an engine 37 and the like are mounted on the swivel unit 32. The traveling unit 33 has, for example, a pair of left and right crawlers, a hydraulic motor (hydraulic actuator) for traveling, and the like. Like the working unit 31, each of the swivel unit 32 and the traveling unit 33 receives power from the engine 37 as a power source and operates. In other words, the swivel unit 32 and the traveling unit 33 operate when hydraulic oil is supplied from a hydraulic pump to the hydraulic actuators (hydraulic motors) of the swivel unit 32 and the traveling unit 33.

[0026] As described above, the engine 37 functions as a power source that supplies power to each component. In this embodiment, as an example, the engine 37 is a diesel engine. The engine 37 is driven by fuel (here, diesel) supplied from a fuel tank. The fuel tank is provided with a fuel level sensor that detects the remaining amount of fuel, and the fuel level sensor outputs an electric signal (sensor signal) corresponding to the detected remaining amount of fuel.

[0027] The cooling water temperature sensor 34 is a sensor that detects the temperature of the cooling water in the radiator (cooling water temperature). The hydraulic oil temperature sensor 35 is a sensor that detects the temperature of the hydraulic oil (hydraulic oil temperature) supplied from the hydraulic pump to the hydraulic actuators in each part of the aircraft 30. The cooling water temperature sensor 34 and the hydraulic oil temperature sensor 35 are both provided in the aircraft 30, and output an electrical signal (sensor signal) corresponding to the detected temperature (cooling water temperature, hydraulic oil temperature).

[0028] The camera 36 has a function of capturing images of the surroundings of the work machine 3. The camera 36 is provided, for example, on the swivel section 32, and is configured to be able to capture images of the surroundings of the work machine 3 (at least one direction of the front, rear, left, right, up, and down). The images captured by the camera 36 may be black and white images, infrared images, or full-color images, and may be either still images or video. As an example in this embodiment, the camera 36 captures an image behind the work machine 3 (surrounding image) as a full-color video, and outputs image data of the surrounding image in real time.

[0029] In addition to the above-mentioned configuration, the machine body 30 further includes an electronic control unit (ECU), a communication terminal, a fuel tank, a battery, etc. Furthermore, the machine body 30 also includes a tachometer that measures the RPM of the engine 37, an hour meter that measures the operating time, and other sensors that detect the state of the cut-off lever, gate lock lever, starter key switch, etc., or the type of attachment attached to the working unit 31, etc.

[0030] [4] Display system Next, the configuration of the display system 10 will be described in detail with reference to Fig. 1 and Fig. 2. As described above, the display system 10 includes the display control system 1 and the display device 2. In the present embodiment, as an example, the display control system 1 and the display device 2 are accommodated in a single housing, and all functions of the display system 10 are concentrated in the single housing as shown in Fig. 2.

[0031] The display system 10 in which the display control system 1 and the display device 2 are integrated in this manner is mounted in the cab of the aircraft 30. This allows a user (operator) to visually recognize the display screen D1 displayed on the display device 2, and also allows the user to operate the display device 2 as necessary.

[0032] 1 and 2, the display device 2 includes a display unit 21 and an operation unit 22. The display device 2 is configured to be able to communicate with the display control system 1, and is able to send and receive data between the display control system 1. In this embodiment, as an example, the display device 2 is a dedicated device used in the work machine 3.

[0033] The display unit 21 is a user interface for presenting information to a user (operator), such as a liquid crystal display or an organic EL display that displays various information. The display unit 21 presents various information to the user by display. In the present embodiment, as an example, the display unit 21 is a full-color liquid crystal display with a backlight, and has a "landscape-long" display area that is long in the horizontal direction, as shown in FIG. 2.

[0034] The operation unit 22 is a user interface for accepting operation input by a user (operator) to the display screen D1 displayed on the display unit 21. The operation unit 22 accepts various operations by the user, for example, by outputting an electric signal according to the user's operation. As an example in this embodiment, the operation unit 22 includes a plurality of (six here) mechanical push button switches 221-226 as shown in FIG. 2. These plurality of push button switches 221-226 are arranged close to the display area (below in the example of FIG. 2) so as to follow the periphery of the display area of ​​the display unit 21. These plurality of push button switches 221-226 are associated with items displayed on the display screen D1 described later, and by operating any one of the plurality of push button switches 221-226, any one of the items on the display screen D1 is operated (selected).

[0035] Furthermore, the operation unit 22 may include a touch panel, an operation dial, etc. In this case as well, an operation on the operation unit 22 causes an operation (selection) of any item on the display screen D1.

[0036] 1, the display control system 1 includes a data acquisition unit 11, an image acquisition unit 12, and a display processing unit 13. The display control system 1 is configured to be able to communicate with the aircraft 30, and can receive, for example, outputs (sensor signals) of the cooling water temperature sensor 34 and the hydraulic oil temperature sensor 35, outputs (image data of peripheral images) of the camera 36, ​​and outputs of other sensors from the aircraft 30. Here, the display control system 1 may acquire this information (data) directly from the cooling water temperature sensor 34, the hydraulic oil temperature sensor 35, the camera 36, ​​etc., or may acquire it via an electronic control unit of the aircraft 30.

[0037] The data acquisition unit 11 periodically or irregularly acquires various data including the output (sensor signal) of the coolant temperature sensor 34 and the output (sensor signal) of the hydraulic oil temperature sensor 35 from the aircraft 30. That is, the data acquisition unit 11 acquires detection results (detection values) of various sensors including data indicating the temperature of the coolant (coolant temperature) and the temperature of the hydraulic oil (hydraulic oil temperature) of the engine 37. In this embodiment, the data acquisition unit 11 also acquires the output (sensor signal) of the remaining amount sensor, that is, data indicating the remaining amount of fuel, from the aircraft 30. The data acquired by the data acquisition unit 11 is stored, for example, in a memory or the like.

[0038] The image acquisition unit 12 periodically or irregularly acquires the output of the camera 36 (image data of the surrounding image) from the machine body 30. In other words, the image acquisition unit 12 acquires an image of the surroundings of the work machine 3 (in this embodiment, an image behind the work machine 3). The data acquired by the image acquisition unit 12 is stored in, for example, a memory or the like.

[0039] The display processing unit 13 mainly comprises a computer system having one or more processors such as a CPU (Central Processing Unit) and one or more memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and executes various processes (information processing). The display processing unit 13 has a function of displaying at least a display screen D1 on the display device 2. Specifically, the display processing unit 13 generates the display screen D1 based on data acquired by the data acquisition unit 11 and the image acquisition unit 12, and controls the display device 2 to display the display screen D1 on the display unit 21 of the display device 2. Furthermore, the display processing unit 13 operates in response to an operation received by an operation unit 22 of the display device 2.

[0040] [5] Display control method 3 to 8, an example of a work machine display control method (hereinafter simply referred to as a "display control method") executed mainly by the display control system 1 will be described below. That is, the display control method according to this embodiment includes (processing) displaying a display screen D1, which will be described below, on the display device 2.

[0041] The display control method according to this embodiment is executed by a display control system 1 having a computer system as its main component, and in other words is embodied in a display control program for a work machine (hereinafter simply referred to as a "display control program"). In other words, the display control program according to this embodiment is a computer program for causing one or more processors to execute each process related to the display control method. The display control program according to this embodiment is a program for causing one or more processors to execute (process) displaying the display screen D1 described below on the display device 2. Such a display control program may be executed, for example, by the display control system 1 and the display device 2 in cooperation with each other.

[0042] Here, when a specific preset start operation is performed to execute the display control program, the display control system 1 executes the various processes described below related to the display control method. The start operation is, for example, an operation to start the engine 37 of the work machine 3. On the other hand, when a specific preset end operation is performed, the display control system 1 ends the various processes described below related to the display control method. The end operation is, for example, an operation to stop the engine 37 of the work machine 3.

[0043] [5.1] Display screen Here, first, the configuration of the display screen D1 displayed on the display unit 21 of the display device 2 by the display control method will be described. In the drawings showing the display screen D1 displayed on the display unit 21 of the display device 2, such as Fig. 3, the dashed dotted lines, leader lines and reference symbols representing areas are all added for the purpose of explanation only and are not actually displayed on the display device 2. Furthermore, in Fig. 3, a "point" indicating the center C1 of the display screen D1 is depicted, but this "point" is also an imaginary point that is not actually displayed on the display device 2.

[0044] The display screen D1 shown in Fig. 3 is a home screen D11 that is initially displayed by the display control method. The home screen D11 is a basic display screen D1 that is initially displayed on the display device 2 while the work machine 3 is in operation. The display screen D1 can transition from the home screen D11 to various display screens D1 including a camera screen D12 (see Fig. 4), a full display screen D13 (see Fig. 4), a menu screen, a crane screen, a mode screen, a PTO screen, and the like, in accordance with an operation on the operation unit 22.

[0045] The home screen D11 as the display screen D1 includes a remaining amount display area R1 (first area) and a switching display area R2 (second area) as shown in Fig. 3. The home screen D11 further includes a third area R3, a fourth area R4, a fifth area R5, a sixth area R6, a seventh area R7, an eighth area R8, a ninth area R9, and a tenth area R10.

[0046] Specifically, the home screen D11 is divided into four regions in the vertical direction (up and down direction). The top three regions are further divided into three regions in the horizontal direction (left and right direction). As a result, the home screen D11 is divided into a total of ten regions. The second region from the top is, from the left, a remaining amount display region R1, a switching display region R2, and a third region R3. The bottom region is a fourth region R4. The third region from the top is, from the left, a fifth region R5, a sixth region R6, and a seventh region R7, and the top region is, from the left, an eighth region R8, a ninth region R9, and a tenth region R10. In terms of vertical size, the second region from the top (remaining amount display region R1, switching display region R2, and third region R3) is the largest among the four regions divided vertically. In terms of horizontal size, the middle area (switchable display area R2, sixth area R6, and ninth area R9) is the largest among the three areas divided horizontally.

[0047] However, the arrangement and size of each of these regions are merely examples and can be changed as appropriate. Also, it is not essential that each region is clearly divided by a boundary line. For example, in the example of Fig. 3, the switching display region R2 and the third region R3 are clearly divided by a boundary line, whereas there is no boundary line between the remaining amount display region R1 and the switching display region R2. Of course, the remaining amount display region R1 and the switching display region R2 may be clearly divided by a boundary line.

[0048] The remaining amount display area R1 is a vertically long rectangular area. The remaining amount display area R1 displays remaining amount information G1 relating to the remaining amount of the monitored object. Here, the monitored object is an object (including liquid and gas) consumed in conjunction with the operation of the work machine 3. In this embodiment, as an example, the monitored object includes fuel (e.g., diesel) for the engine 37. That is, the remaining amount display area R1 displays remaining amount information G1 relating to the remaining amount of the fuel, which is the monitored object. The display processing unit 13 generates remaining amount information G1 in the display screen D1 (home screen D11) based on the output (sensor signal) of the remaining amount sensor acquired by the data acquisition unit 11.

[0049] In this embodiment, the remaining amount information G1 is a bar graph. That is, the remaining amount information G1 is information in which the remaining amount of the monitored object (here, fuel) is indexed and represented by the length (height) of the bar graph. By displaying the remaining amount information G1 as a graph (bar graph), there is an advantage that the user can easily see and intuitively understand the remaining amount of the monitored object. The remaining amount information G1 may be information related to the remaining amount of the monitored object, and may be not only information that represents the remaining amount itself as a numerical value or the like, but also information that represents the remaining amount in stages using pictures (icons) and the like, and information that indirectly represents the remaining amount by representing the consumption amount of the monitored object.

[0050] The switching display area R2 is a rectangular area that is long in the horizontal direction. Display target information is displayed in the switching display area R2. Here, the display target information is information that is switchably selected from a plurality of pieces of information including at least first information and second information related to the work machine 3. In the example of FIG. 3, the cooling water temperature information G3 and the hydraulic oil temperature information G2 are displayed in the switching display area R2. The cooling water temperature information G3 and the hydraulic oil temperature information G2 are first information related to the work machine 3. In other words, the home screen D11 shown in FIG. 3 is the display screen D1 in a state in which the first information (cooling water temperature information G3 and hydraulic oil temperature information G2) is displayed in the switching display area R2 as display target information. Both the cooling water temperature information G3 and the hydraulic oil temperature information G2 are information related to the work machine 3, and in particular, information related to the operating state of the work machine 3.

[0051] That is, information relating to the operating state of the work machine 3 can be displayed as the first information in the switching display region R2. The display processing unit 13 generates coolant temperature information G3 on the display screen D1 (home screen D11) based on the output (sensor signal) of the coolant temperature sensor 34 acquired by the data acquisition unit 11. Similarly, the display processing unit 13 generates hydraulic oil temperature information G2 on the display screen D1 (home screen D11) based on the output (sensor signal) of the hydraulic oil temperature sensor 35 acquired by the data acquisition unit 11.

[0052] In this embodiment, the cooling water temperature information G3 and the hydraulic oil temperature information G2 are both graphs imitating an analog meter. In the analog meter, needles G21, G31 rotate, and a value is displayed according to the position of the needles G21, G31. In other words, the cooling water temperature information G3 is information in which the cooling water temperature included in the operating state of the work machine 3 is indexed and represented by the position of the needle G31 of the graph. Similarly, the hydraulic oil temperature information G2 is information in which the hydraulic oil temperature included in the operating state of the work machine 3 is indexed and represented by the position of the needle G21 of the graph. By displaying the cooling water temperature information G3 and the hydraulic oil temperature information G2 as a graph, there is an advantage that the user can easily recognize the information and can intuitively understand the operating state of the work machine 3. The cooling water temperature information G3 and the hydraulic oil temperature information G2 may not only be information in which the cooling water temperature and the hydraulic oil temperature are represented by numerical values ​​or the like, but may also be information in which the cooling water temperature and the hydraulic oil temperature are represented in stages by pictures (icons) or the like, for example.

[0053] In short, in this embodiment, the first information is information relating to the operating state of the work machine 3. This allows the user to understand the operating state of the work machine 3 from the first information displayed in the switching display area R2 of the display screen D1. Furthermore, in this embodiment, the first information is information that represents the operating state in an index form. Therefore, the user can understand the operating state of the work machine 3 in detail.

[0054] Incidentally, the display target information displayed in the switching display area R2 is information that is switchably selected from a plurality of pieces of information including the first information and the second information, and is not limited to the above-mentioned first information (the cooling water temperature information G3 and the hydraulic oil temperature information G2). In other words, the switching display area R2 can display the second information, which is different from the first information and is related to the work machine 3, in place of the first information.

[0055] In this embodiment, an example of the second information is a surrounding image G4 (see FIG. 6) captured by the camera 36. In other words, the second information is information that includes a surrounding image of the work machine 3. In this way, the display target information displayed in the switch display area R2 is switched among a plurality of pieces of information including the first information and the second information, so that, for example, information required by the user depending on the situation at that time can be preferentially displayed on the display screen D1.

[0056] The third area R3 is a vertically long rectangular area. In the third area R3, an icon Im1 corresponding to the operating state of each part of the work machine 3 is displayed. In the third area R3, a plurality of icons Im1 can be displayed, and the design (pattern) of each icon Im1 indicates which state it represents, for example, the battery, seat belt, cooling water temperature, hydraulic oil temperature, etc. Here, each icon Im1 indicates the operating state by, for example, a display mode such as a display color or size. The display processing unit 13 determines the state of each part of the work machine 3 using the output of various sensors (including the cooling water temperature sensor 34 and the hydraulic oil temperature sensor 35) that detect the operating state of each part of the work machine 3. Then, when an abnormal value is detected in any part, the display processing unit 13 displays a warning by changing the display mode, such as the display color, of the icon Im1 of that part.

[0057] The fourth region R4 is a strip-shaped region extending across the entire width of the display screen D1. In the fourth region R4, various items for operating the display screen D1 are displayed. In FIG. 3, as an example, the fourth region R4 has six items, "menu", "crane", "mode", "camera", "PTO", and "switch", arranged in this order from the left. These six items are associated with six pushbutton switches 221 to 226 of the operation unit 22 located directly below them. For example, the "menu" item is associated with the pushbutton switch 221, and the "crane" item is associated with the pushbutton switch 222. Therefore, for example, when the pushbutton switch 224 corresponding to the "camera" item is operated by the user U1 (see FIG. 2), the "camera" item is operated (selected).

[0058] Furthermore, in this embodiment, in order to correspond to the operation of the operation dial (or cursor key) of the operation unit 22, any of the items is highlighted in the fourth region R4. In the example of FIG. 3, the item "Menu" is highlighted, and the highlighted item is switched by the operation of the operation dial (or cursor key). The user U1 can select the desired item by operating the decision button with the desired item highlighted. Therefore, for example, when the decision button is operated with the highlight moved to the "Camera" item, the "Camera" item is operated (selected). Furthermore, in the case where the operation unit 22 includes a touch panel, the user U1 can select the desired item by touching the desired item on the display screen D1.

[0059] The fifth area R5 displays presentation information Im2 (see FIG. 5), which will be described later. The sixth area R6 displays, for example, information related to the working unit 31 currently operating in the work machine 3. The seventh area R7 displays, for example, information related to the operating state of the work machine 3, such as the RPM of the engine 37 (see FIG. 5). The eighth area R8 displays, for example, the current time. The ninth area R9 displays, for example, information indicating the item to which the currently displayed display screen D1 belongs. The tenth area R10 displays, for example, information related to the operating time (hour meter) of the work machine 3.

[0060] In the display screen D1 (home screen D11) as described above, the switching display region R2 is disposed in a central area including the center C1 of the display screen D1. That is, as shown in FIG. 3, when a central area (same range as the switching display region R1) including the center C1 of the display screen D1 is defined in the display screen D1, display target information that is switchably selected from a plurality of pieces of information including the first information and the second information is displayed in the central area. On the other hand, the remaining amount display region R1 is disposed in a peripheral area located around the central area of ​​the display screen D1. That is, as shown in FIG. 3, when a central area including the center C1 of the display screen D1 is defined in the display screen D1, the remaining amount information G1 is displayed in a peripheral area close to the edge of the display screen D1.

[0061] In short, the display control system 1 according to this embodiment includes a display processing unit 13 that displays a display screen D1 on the display device 2. The display screen D1 includes a remaining amount display area R1 and a switching display area R2. The remaining amount display area R1 is an area that displays remaining amount information G1 relating to the remaining amount of a monitored object consumed in association with the operation of the work machine 3. The switching display area R2 is an area that displays display target information that is switchably selected from a plurality of pieces of information including at least first information and second information related to the work machine 3. The switching display area R2 is disposed in a central area including the center C1 of the display screen D1. The remaining amount display area R1 is disposed in a peripheral area located around the central area of ​​the display screen D1.

[0062] According to this configuration, the remaining amount information G1, which is preferably always displayed on the display screen D1, can be easily displayed at the edge (peripheral area) of the display screen D1 without overlapping with the display of other information. Meanwhile, for example, the first information such as the cooling water temperature information G3 and the hydraulic oil temperature information G2 is displayed in the center (central area) of the display screen D1, so that the information that is prioritized when the work machine 3 is in operation can be easily displayed in a particularly conspicuous and highly visible position. Moreover, since the information displayed in the switchable display area R2 can be switched, it is possible to switch the information displayed in the highly visible position (central area) from time to time. Therefore, the display control system 1 according to this embodiment has the advantage that it is easy to improve the visibility of each of the various pieces of information related to the work machine 3.

[0063] Meanwhile, as shown in FIG. 4, the display processing unit 13 transitions the display screen D1 displayed on the display device 2 from the home screen D11 to another screen (such as a camera screen D12 or a full display screen D13) in response to a user operation.

[0064] Here, as an example, as shown in FIG. 4, a home screen D11 is first displayed on the display unit 21 of the display device 2 by a start operation. Then, when the "camera" item is operated (selected) by operating the push button switch 224 corresponding to the "camera" item while the home screen D11 is displayed, the home screen D11 transitions to a camera screen D12. When the "camera" item is operated (selected) while the camera screen D12 is displayed, the camera screen D12 transitions to a full display screen D13. Furthermore, when any item is operated (selected) while the full display screen D13 is displayed, the full display screen D13 transitions to the home screen D11. However, the operation for transition of the display screen D1 and the order of transition are not limited to the above example and can be changed as appropriate.

[0065] That is, the display screen D1 displayed on the display device 2 can be switched, for example, from a home screen D11 as shown in Fig. 5 to a camera screen D12 as shown in Fig. 6. Furthermore, the display screen D1 displayed on the display device 2 can also be switched, for example, to a full display screen D13 as shown in Fig. 7.

[0066] The camera screen D12 shown in Fig. 6 is a screen in which only the display content of the switching display area R2 is changed from the home screen D11 shown in Fig. 5. In other words, the display other than the switching display area R2 is the same between the camera screen D12 and the home screen D11.

[0067] In the switching display area R2 of the camera screen D12, second information is displayed as the display target information instead of the first information (cooling water temperature information G3 and hydraulic oil temperature information G2). Here, the second information is information including a peripheral image G4 of the work machine 3. The display processing unit 13 generates the peripheral image G4 in the display screen D1 (camera screen D12) based on the output (image data) of the camera 36 acquired by the image acquisition unit 12. Therefore, according to the camera image D12, the user can easily check the periphery (here, rear) of the work machine 3, which is likely to be a blind spot, in the peripheral image G4 displayed in the center (central area) of the display screen D1. Here, the peripheral image G4 is displayed, as an example, when the engine 37 is running and a cutoff lever that prohibits the operation of the work machine 3 is released, that is, the prohibition of operation is lifted.

[0068] The full display screen D13 shown in Fig. 7 is a screen in which the switching display area R2 in which the peripheral image G4 is displayed is enlarged compared to the camera screen D12 shown in Fig. 6. In the example of Fig. 7, the full display screen D13 includes only two areas, the switching display area R2 and the third area R3, and most of the display screen D1 is the switching display area R2, and only the right end part of the display screen D1 is the third area R3. In other words, in the full display screen D13, the remaining amount display area R1 is not displayed, and the switching display area R2 is enlarged and displayed from the central area to the peripheral area where the remaining amount display area R1 is displayed in the camera screen D12, etc.

[0069] In short, the display processing unit 13 according to this embodiment has a plurality of display modes including a first mode and a second mode. In the first mode, the display processing unit 13 arranges the switch display area R2 in the central area and the remaining amount display area R1 in the peripheral area. In the second mode, the display processing unit 13 hides the remaining amount display area R1 and arranges the switch display area R2 across the central area and the peripheral area. Therefore, the display processing unit 13 displays the home screen D11 and the camera screen D12 in the first mode and displays the full display screen D13 in the second mode.

[0070] According to this configuration, the display processing unit 13 can enlarge and display the switching display area R2 while operating in the second mode, that is, by displaying the full display screen D13. Therefore, the visibility of the information displayed in the switching display area R2 is improved for the user. In this embodiment, in the full display screen D13, the surrounding image G4 is basically displayed as the second information in the switching display area R2, but this configuration is not limited. In other words, in the full display screen D13, the first information such as the cooling water temperature information G3 and the hydraulic oil temperature information G2 may be displayed in the switching display area R2.

[0071] Incidentally, the home screen D11 in FIG. 5 shows a state in which the presentation information Im2 is displayed in the fifth region R5. In the example of FIG. 5, a case is assumed in which an abnormal value is detected for the cooling water temperature. That is, the display processing unit 13 judges the state of each part of the work machine 3, for example, for the operating state of each part of the work machine 3 corresponding to the various icons Im1 displayed in the third region R3, using the outputs of various sensors (including the cooling water temperature sensor 34 and the hydraulic oil temperature sensor 35). As an example, in a case in which the normal range for the cooling water temperature is 30 degrees or more and less than 110 degrees, if the cooling water temperature becomes less than 30 degrees or more than 110 degrees, the display processing unit 13 detects an abnormal value for the cooling water temperature. Then, when such an abnormal value is detected, the display processing unit 13 displays the presentation information Im2 in the fifth region R5 while changing the display mode, such as the display color, of the icon Im1 corresponding to the abnormal value in the third region R3. Furthermore, in the example of FIG. 5, presentation information Im3 indicating that an abnormal value has been detected, such as "Error Occurring", is also displayed in the ninth region R9.

[0072] Here, the presentation information Im2 and Im3 are information related to the first information (cooling water temperature information G3 and hydraulic oil temperature information G2). Specifically, the presentation information Im2 and Im3 are warning displays indicating that an abnormal value has been detected for the first information. Furthermore, the presentation information Im2 and Im3 include an image (icon) representing the first information (cooling water temperature). That is, the presentation information Im2 and Im3 include an image related to the first information. Particularly in this embodiment, the presentation information Im2 expresses the content of the abnormal value by the display mode (display color or size, etc.) of the image. As an example, if the cooling water temperature is less than 30 degrees, the presentation information Im2 is a blue image, and if the cooling water temperature is 110 degrees or more, the presentation information Im2 is a red image. In this way, the presentation information Im2 and Im3 include an image, so that the user can easily understand the content represented by the presentation information Im2 and Im3.

[0073] Furthermore, in the example of Fig. 5, the item at the right end of the fourth region R4 has changed from "switch" (see Fig. 3) to warning Im5. That is, when an abnormal value is detected, the display processing unit 13 displays the warning Im5 item in the fourth region R4 while displaying the presentation information Im2 and Im3. In this state, for example, when the push button switch 226 corresponding to warning Im5 is operated by the user U1 (see Fig. 2), the warning Im5 item is operated (selected). When the warning Im5 item is operated, details of the error (abnormal value) occurring at that time are displayed on the display screen D1.

[0074] In the present embodiment, the presentation information Im2 and Im3 are also displayed on the camera screen D12 in which the second information (peripheral image G4) is displayed in the switching display area R2, as shown in FIG. 6. That is, the display processing unit 13 displays the presentation information Im2 and Im3 related to the first information on the display screen D1 in a state in which at least the first information is not displayed in the switching display area R2. This makes it possible to present information related to the first information to the user by the presentation information Im2 and Im3 even in a state in which the first information is not displayed. In the present embodiment, the presentation information Im2 and Im3 are displayed not only in a state in which the first information is not displayed (camera screen D12) but also in a state in which the first information is displayed (home screen D11). However, as shown in FIG. 7, only the presentation information Im3 of the presentation information Im2 and Im3 is displayed on the full display screen D13.

[0075] In addition, in this embodiment, at least the presentation information Im2 is displayed in the fifth region R5, that is, in a region other than the switching display region R2. The fifth region R5 is located below the remaining amount display region R1. In short, the display processing unit 13 displays the presentation information Im2 at a position other than the switching display region R2 on the display screen D1. This improves the visibility of each piece of information without the presentation information Im2 overlapping the first information or the second information, etc., displayed in the switching display region R2. Furthermore, the display processing unit 13 displays the presentation information Im2 below the remaining amount display region R1 on the display screen D1. This improves the visibility of each piece of information without the presentation information Im2 overlapping the remaining amount information G1 displayed in the remaining amount display region R1.

[0076] [5.2] Overall processing Next, an overall flow of processing related to the display control method will be described with reference to Fig. 8. Fig. 8 is a flowchart showing an example of processing related to the display control method.

[0077] As shown in FIG. 8, the display processing unit 13 of the display control system 1 first displays the home screen D11 on the display device 2. That is, the display processing unit 13 displays first information (e.g., cooling water temperature information G3 and hydraulic oil temperature information G2) related to the operating state of the work machine 3 in the switching display area R2 of the display screen D1 (home screen D11) (S1). Furthermore, the display processing unit 13 displays the remaining amount information G1 in the remaining amount display area R1 of the display screen D1 (home screen D11) (S2). At this time, when the display processing unit 13 displays the operating state and the remaining amount information G1, the display control system 1 uses the data acquired by the data acquisition unit 11. In this state, the display processing unit 13 monitors whether or not an image display operation, that is, an operation (selection) of the "camera" item is performed (S3). If no image display operation is performed (S3: No), the display processing unit 13 continues to display the home screen D11 (S1, S2).

[0078] When an image display operation is performed (S3: Yes), the display processing unit 13 displays the camera screen D12 on the display device 2. That is, the display processing unit 13 displays the peripheral image G4 of the work machine 3 in the switching display area R2 of the display screen D1 (camera screen D12) (S4). The image data acquisition process by the image acquisition unit 12 may be executed for the first time when the peripheral image G4 is displayed, that is, at the time of processing S4. In this state, the display processing unit 13 monitors whether or not a mode switching operation, that is, an operation (selection) of the "camera" item, is performed (S5).

[0079] If a mode switching operation is performed (S5: Yes), the display processing unit 13 displays the full display screen D13 on the display device 2. That is, the display processing unit 13 makes the remaining amount display area R1 non-displayable, and displays the switch display area R2 of the display screen D1 (full display screen D13) full screen (enlarged) (S6). On the other hand, if a mode switching operation is not performed (S5: No), the display processing unit 13 skips the process S6 and continues to display the camera screen D12.

[0080] Then, the display processing unit 13 monitors whether or not an operation to end the image display, that is, an operation (selection) of the "camera" item is performed while the camera screen D12 or the full display screen D13 is displayed (S7). If an operation to end the image display is not performed (S7: No), the display processing unit 13 continues to display the camera screen D12 or the full display screen D13 (S4 to S6). If an operation to end the image display is performed (S7: Yes), the display processing unit 13 returns to process S1 and displays the home screen D11 on the display device 2.

[0081] Here, the data acquisition process by the data acquisition unit 11 and the abnormal value detection (determination) process by the display processing unit 13 are executed constantly (or periodically) as background processes of each process in the above flowcharts. Therefore, even if any process in the above flowcharts is being executed, when an abnormal value is detected in the abnormal value detection process, the display processing unit 13 displays the presentation information Im2 and Im3.

[0082] However, the flowchart shown in FIG. 8 is merely an example, and processes may be added or omitted as appropriate, and the order of processes may be changed as appropriate.

[0083] [6] Variations Below, we will list some modified examples of the embodiment 1. The modified examples explained below can be applied in appropriate combinations.

[0084] FIG. 9 shows a display screen D1 (home screen D11) displayed by the display control system 1 according to the first modified example. In this modified example, a work machine 3 is assumed to have a urea SCR (Selective Catalytic Reduction) system attached to the engine 37. The urea SCR system removes NOx contained in the exhaust gas by injecting urea water into the exhaust gas. In a work machine 3 configured in this way, it is necessary to appropriately replenish not only fuel but also the urea water in the urea water tank. Therefore, in this modified example, the remaining amount information G1 displayed in the remaining amount display area R1 includes urea water remaining amount information G12 related to the remaining amount of urea water in addition to fuel remaining amount information G11 related to the remaining amount of fuel. Both the fuel remaining amount information G11 and the urea water remaining amount information G12 are bar graphs. In this modified example, a fuel consumption rate is also displayed in the seventh area R7.

[0085] In this way, the remaining amount information G1 displayed in the remaining amount display area R1 is not limited to the remaining amount of fuel, and may include information regarding the remaining amounts of various monitored objects. The remaining amount information G1 may display information regarding the remaining amounts of multiple monitored objects simultaneously, or may display the information individually. Furthermore, for example, what is included in the monitored objects may be automatically determined by the display processing unit 13 through communication with the machine body 30 of the work machine 3, or may be set manually.

[0086] The display control system 1 in the present disclosure includes a computer system. The computer system mainly comprises one or more processors and one or more memories as hardware. The processor executes a program recorded in the memory of the computer system to realize the functions of the display control system 1 in the present disclosure. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or may be recorded and provided in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. In addition, some or all of the functional units included in the display control system 1 may be configured with electronic circuits.

[0087] Furthermore, it is not an essential configuration for the display control system 1 that at least some of the functions of the display system 10 are concentrated in one housing, and the components of the display system 10 may be distributed across multiple housings. Conversely, in the first embodiment, the functions of the display system 10 and the like that are distributed across multiple devices may be concentrated in one housing. Furthermore, at least some of the functions of the display control system 1 may be realized by the cloud (cloud computing) or the like.

[0088] Furthermore, the power source of the work machine 3 is not limited to a diesel engine, and may be, for example, an engine other than a diesel engine, a motor (electric motor), or a hybrid power source including an engine and a motor (electric motor). When the power source includes an electric motor such as a motor, the power source is driven by consuming electric energy stored in a battery in addition to or instead of fuel (diesel oil, gasoline, etc.). In this case, for example, the SOC (State Of Charge) equivalent to the remaining capacity of the battery or the like may be displayed on the display screen D1 as remaining capacity information G1.

[0089] Furthermore, the peripheral image captured by the camera 36 is not limited to an image behind the work machine 3, and may include, for example, an image in at least one direction of the front, left, right, above, and below the work machine 3, in addition to or instead of the image behind the work machine 3. If a plurality of cameras 36 are provided, by switching between these multiple cameras 36, it may be possible to switch between, for example, an image behind the work machine 3 and an image in front of the work machine 3 and display them on the display screen D1.

[0090] The display device 2 is not limited to a dedicated device, and may be, for example, a general-purpose terminal such as a laptop computer, a tablet terminal, or a smartphone. The display unit 21 is not limited to a mode in which the display screen D1 is directly displayed, such as a liquid crystal display or an organic EL display, and may be configured to display the display screen D1 by projection, such as a projector. The display area of ​​the display unit 21 is not limited to a horizontally long area, and may be vertically long.

[0091] Furthermore, the information input form of the operation unit 22 may be other than the push button switches 221 to 226, the touch panel, and the operation dial. For example, the operation unit 22 may be a keyboard, a pointing device such as a mouse, a voice input, a gesture input, or an input of an operation signal from another terminal.

[0092] Furthermore, the first information displayed in the switching display area R2 is not limited to the coolant temperature information G3 and the hydraulic oil temperature information G2. For example, the first information may be only one of the coolant temperature information G3 and the hydraulic oil temperature information G2, or may include information about the working unit 31 in operation, as displayed in the sixth area R6.

[0093] The above-mentioned arrangement and size of the remaining amount display area R1 and the switching display area R2 are also merely examples and can be changed as appropriate. For example, the switching display area R2 may be arranged in the peripheral area and the remaining amount display area R1 in the central area. Furthermore, at least one of the remaining amount display area R1 and the switching display area R2 may be omitted as appropriate.

[0094] (Embodiment 2) A display system 10A according to this embodiment differs from the display system 10 according to the first embodiment in that the display system 10A is provided separately from the body 30 of the work machine 3A, as shown in Fig. 10. Hereinafter, common reference symbols are used for configurations similar to those of the first embodiment, and descriptions thereof will be omitted as appropriate.

[0095] In this embodiment, as an example, the work machine 3A operates by automatic driving (autonomous travel). Specifically, the work machine 3A includes a position detection unit that detects the position (latitude and longitude) of the machine body 30 using a satellite positioning system such as a Global Navigation Satellite System (GNSS), an attitude detection unit that detects the attitude of the work machine 3A, and the like.

[0096] A display system 10A equipped with the display control system 1A and the display device 2A is realized by a tablet terminal or the like arranged outside the work machine 3A. In this embodiment, the display control system 1A is equipped with a communication unit 14. The machine body 30 of the work machine 3A is equipped with a machine body-side communication unit 38. The communication unit 14 and the machine body-side communication unit 38 are configured to be able to communicate with each other via a communication network N1 such as the Internet.

[0097] According to this configuration, even if the display system 10A is provided separately from the machine body 30 of the work machine 3A, it is possible to display the same display screen D1 as in the first embodiment on the display device 2A by communicating with the machine body 30.

[0098] As a modification of this embodiment, the work machine 3A is not limited to a configuration that operates by automatic driving, and may be operated by remote operation of a user (operator). In this case, the user remotely operates the work machine 3A while, for example, viewing the display screen D1 displayed on the display device 2A.

[0099] The configuration according to the second embodiment (including the modified examples) can be adopted in appropriate combination with the various configurations (including the modified examples) described in the first embodiment.
