Technical Field

[0001] This application claims priority based on Japanese Patent Application No. 2024-171366, filed on September 30, 2024. The entire contents of that Japanese application are incorporated herein by reference.

[0002] This invention relates to construction machinery and portable terminal devices for construction machinery. Background Technology

[0003] Previously, there was a known excavator equipped with a display device that displayed information related to the weight of an object loaded in the cargo box of a transport vehicle such as a dump truck, i.e., payload information (see Patent Document 1).

[0004] Patent Document 1: Japanese Patent Application Publication No. 2024-095024

[0005] In such excavators, a printer for printing payload information is sometimes installed in the cab. This is to allow the excavator operator to pass a paper (a passbook) containing the payload information to the driver of the transport vehicle. However, this method is inefficient because printing and passing the passbook is labor-intensive.

[0006] Therefore, it is desirable to reduce the workload associated with operators of construction machinery such as excavators transmitting payload information to drivers of transport vehicles. Summary of the Invention

Detailed Implementation

[0023] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, the embodiments described below are illustrative rather than limiting, and all features and combinations thereof described in the embodiments are not necessarily the essence of the invention. Additionally, in the accompanying drawings, the same or corresponding structures are sometimes labeled with the same or corresponding symbols, and descriptions are omitted.

[0024] First, refer to Figure 1 An overview of the construction machinery management system SYS according to embodiments of the present invention will be provided. Figure 1 This is a schematic diagram representing the structure of the management system SYS.

[0025] like Figure 1As shown, the management system SYS includes construction machinery 100, transport vehicles 200, and a management center 300. The construction machinery 100 and the management center 300 are connected via communication lines NW to enable data transmission and reception. In the example shown, the construction machinery 100 is configured to transmit and receive data with the management center 300 via the communication lines NW.

[0026] Specifically, the construction machinery 100 can, for example, send information related to the weight of objects loaded in the cargo box of a transport vehicle 200, such as a dump truck, i.e., payload information, to the management center 300. In the example shown, the payload information is acquired (generated) based on the output of the information acquisition device (IAD) installed on the construction machinery 100. Thus, the manager at the management center 300 can confirm the content of the payload information from the construction machinery 100. Furthermore, the information acquisition device (IAD) for acquiring payload information can be not only a device installed on the construction machinery 100, but also a device installed on a drone or other flying object operating at the construction site, a fixed-point camera installed at the construction site, or a camera device carried by workers at the construction site.

[0027] The management system SYS can include one or more construction machines 100. Therefore, the management system SYS can manage the payload information associated with each of the multiple construction machines 100. Furthermore, the management system SYS can include one or more management centers 300.

[0028] Furthermore, in this embodiment, the construction machinery 100 has a driver's cab 10 serving as the operator's compartment, within which a wireless communication device 50 and a display device 40 are installed. The wireless communication device 50 is configured to communicate with a portable terminal device SP1, such as a smartphone, carried by the operator OP, who sits in the operator's seat within the driver's cab 10. In the illustrated example, communication between the wireless communication device 50 and the portable terminal device SP1 is achieved through direct wireless communication. "Direct wireless communication" between the wireless communication device 50 and the portable terminal device SP1 refers to wireless communication conducted directly between the two devices without relying on a communication satellite or ground base station. However, "direct wireless communication" between the wireless communication device 50 and the portable terminal device SP1 also includes wireless communication via a repeater located between the two devices. The same applies to direct wireless communication between the portable terminal device SP1 and the driver's portable terminal device SP2. Alternatively, communication between the wireless communication device 50 and the portable terminal device SP1 can also be achieved through wired communication. At this time, the operator's portable terminal device SP1 can be held in place by a bracket or other holding component installed in the cockpit 10. Furthermore, the display device 40 is positioned at a location that the operator OP, seated in the driver's seat within the cockpit 10, can visually perceive.

[0029] Furthermore, in this embodiment, the cockpit 10 is configured to enable direct wireless communication between the driver's portable terminal device SP2 (such as a smartphone) carried by the driver's DV, which is located in the driver's seat within the cab 210 of the transport vehicle 200, and the operator's portable terminal device SP1. Additionally, the operator's portable terminal device SP1 can be configured to enable direct wireless communication with an on-board terminal device mounted on the transport vehicle 200. In this case, the on-board terminal device can be configured to enable direct wireless communication or wired communication with the driver's portable terminal device SP2. Furthermore, the driver's portable terminal device SP2 can be configured to enable direct wireless communication with the wireless communication device 50.

[0030] In the example shown, the wireless communication device 50 is configured to enable information exchange between the wireless communication device 50 and the operator's portable terminal device SP1 via Bluetooth (registered trademark). However, the wireless communication device 50 may also be configured to enable information exchange between the wireless communication device 50 and the operator's portable terminal device SP1 via a wireless LAN such as Wi-Fi (registered trademark). Furthermore, the wireless communication device 50 may be configured to enable wired communication between the wireless communication device 50 and the operator's portable terminal device SP1.

[0031] Furthermore, in the illustrated example, the direct wireless communication between the operator's portable terminal device SP1 and the driver's portable terminal device SP2 is implemented using Bluetooth (registered trademark). Specifically, this direct wireless communication can be established without pairing. "Pairing" refers to an example of the preparatory operation for establishing direct wireless communication, and specifically refers to the operation that allows communication between the two devices corresponding to Bluetooth (registered trademark). For example, if both the operator's portable terminal device SP1 and the driver's portable terminal device SP2 are iPhones (registered trademark), the direct wireless communication is implemented using software for sharing data, namely AirDrop (registered trademark). Alternatively, if both the operator's portable terminal device SP1 and the driver's portable terminal device SP2 are Android smartphones (registered trademark), the direct wireless communication is implemented using software for sharing data, namely Quick Share.

[0032] However, direct wireless communication between the operator's portable terminal device SP1 and the driver's portable terminal device SP2 can also be established through preparatory operations such as pairing. In this case, the direct wireless communication can be implemented using Wi-Fi (registered trademark). Furthermore, wireless communication between the operator's portable terminal device SP1 and the driver's portable terminal device SP2 can be implemented using mobile phone communication networks or satellite communication networks. In this case, the exchange of payload information between the operator's portable terminal device SP1 and the driver's portable terminal device SP2 can be implemented using email.

[0033] Next, refer to Figure 2 The detailed structure of construction machinery 100 is described. Figure 2This is a side view of an excavator (earthworker) as an example of construction machinery 100. Construction machinery 100 can be a crane or a forklift. In the example shown, an upper slewing body 3 is rotatably mounted on the lower traveling body 1 of the construction machinery 100 via a slewing mechanism 2. A boom 4 is mounted on the upper slewing body 3, a stick 5 is mounted at the front end of the boom 4, and a bucket 6 as an end-attachment is mounted at the front end of the stick 5. The end-attachment can be a breaker or a grappling hook, etc.

[0034] The boom 4, stick 5, and bucket 6 constitute an excavation attachment as an example of an auxiliary device AT, and are driven by a boom cylinder 7, stick cylinder 8, and bucket cylinder 9, which are hydraulic cylinders, as examples of working actuators WA. Furthermore, a boom angle sensor S1 is installed on the boom 4, a stick angle sensor S2 is installed on the stick 5, and a bucket angle sensor S3 is installed on the bucket 6.

[0035] The boom angle sensor S1 detects the rotation angle of the boom 4. In this embodiment, the boom angle sensor S1 is an acceleration sensor capable of detecting the boom angle, which is the rotation angle of the boom 4 relative to the upper rotating body 3. The boom angle is, for example, the minimum angle when the boom 4 is lowered to the maximum extent, and increases as the boom 4 is raised.

[0036] The stick angle sensor S2 detects the rotation angle of the stick 5. In this embodiment, the stick angle sensor S2 is an acceleration sensor capable of detecting the stick angle, which is the rotation angle of the stick 5 relative to the boom 4. The stick angle is, for example, the minimum angle when the stick 5 is retracted to its maximum extent, and increases as the stick 5 is extended.

[0037] The bucket angle sensor S3 detects the rotation angle of the bucket 6. In this embodiment, the bucket angle sensor S3 is an acceleration sensor capable of detecting the bucket angle, which is the rotation angle of the bucket 6 relative to the stick 5. The bucket angle is, for example, the minimum angle when the bucket 6 is retracted to its maximum extent, and increases as the bucket 6 is opened.

[0038] The boom angle sensor S1, stick angle sensor S2, and bucket angle sensor S3 can also be a potentiometer using a variable resistor, a stroke sensor that detects the stroke of the corresponding hydraulic cylinder, or a rotary encoder that detects the rotation angle around the connecting pin, etc. Furthermore, the boom angle sensor S1, stick angle sensor S2, and bucket angle sensor S3 constitute a posture sensor AS for detecting the posture of the excavating attachment.

[0039] The boom bottom pressure sensor S7B is a pressure sensor used to detect the pressure of the working oil in the bottom-side oil chamber of the boom cylinder 7, i.e., the boom bottom pressure. The boom rod pressure sensor S7R is a pressure sensor used to detect the pressure of the working oil in the rod-side oil chamber of the boom cylinder 7, i.e., the boom rod pressure. The stick bottom pressure sensor S8B is a pressure sensor used to detect the pressure of the working oil in the bottom-side oil chamber of the stick cylinder 8, i.e., the stick bottom pressure. The stick rod pressure sensor S8R is a pressure sensor used to detect the pressure of the working oil in the rod-side oil chamber of the stick cylinder 8, i.e., the stick rod pressure. The bucket bottom pressure sensor S9B is a pressure sensor used to detect the pressure of the working oil in the bottom-side oil chamber of the bucket cylinder 9, i.e., the bucket bottom pressure. The stick pressure sensor S9R is a pressure sensor used to detect the pressure of the working oil in the rod-side oil chamber of the bucket cylinder 9, i.e., the stick pressure. In the example shown, the boom bottom pressure sensor S7B is located in the oil circuit connecting the bottom-side oil chamber of the boom cylinder 7 and the control valve unit 17, but it can also be located within the boom cylinder 7 itself. The same applies to the boom rod pressure sensor S7R, stick bottom pressure sensor S8B, stick rod pressure sensor S8R, bucket bottom pressure sensor S9B, and stick pressure sensor S9R.

[0040] The upper rotating body 3 is equipped with a cockpit 10, an engine 11, a positioning device PD, a fuselage tilt sensor S4, a slewing angular velocity sensor S5, a spatial identification device S6, a slewing actuator SA, and a communication device T1.

[0041] An excavator controller 30 and a wireless communication device 50 are installed inside the cab 10. The cab 10 also includes an operator's seat, operating devices 26, and a display device 40. The excavator controller 30 is a control device that performs various calculations. The excavator controller 30 is located inside the cab 10 and performs drive control of the construction machinery 100. The functions of the excavator controller 30 can be implemented by any hardware, software, or a combination thereof. For example, the excavator controller 30 may be composed of a microcomputer including a CPU, RAM (volatile memory), ROM (non-volatile memory), and various input / output interface devices. The excavator controller 30 can, for example, implement various functions by executing various programs installed on the non-volatile memory on the CPU.

[0042] Engine 11 is an example of the drive source for construction machinery 100. In the example shown, engine 11 is a diesel engine and is mounted at the rear of the upper rotating body 3. The output shaft of engine 11 is connected to the input shafts of the main pump 14 and the pilot pump 15, respectively. Specifically, under the direct or indirect control of the excavator controller 30, engine 11 rotates at a constant target speed set in advance, driving the main pump 14 and the pilot pump 15, etc. Alternatively, the drive source for construction machinery 100 can be a battery-powered electric motor. That is, construction machinery 100 can be a hybrid construction machine or an electric construction machine.

[0043] The body tilt sensor S4 is configured to detect the tilt angle of the upper rotating body 3 relative to a predetermined plane. In the example shown, the body tilt sensor S4 is an acceleration sensor that detects the tilt angle of the upper rotating body 3 about the front and rear axes and the tilt angle about the left and right axes relative to the horizontal plane. The front and rear axes and the left and right axes of the upper rotating body 3 are, for example, orthogonal to each other and pass through a center point, which is a point on the rotation axis PV of the construction machinery 100.

[0044] The rotational angular velocity sensor S5 is configured to detect the rotational angular velocity of the upper rotating body 3. In this embodiment, the rotational angular velocity sensor S5 is a gyroscope sensor. The rotational angular velocity sensor S5 can also be a rotary transformer or a rotary encoder, etc. Furthermore, the rotational angular velocity sensor S5 can be configured to detect the rotational speed. Moreover, the rotational speed can be calculated based on the rotational angular velocity.

[0045] The spatial recognition device S6 is configured to acquire images of the area surrounding the construction machinery 100. In the example shown, the spatial recognition device S6 includes a front camera S6F that captures images of the space in front of the construction machinery 100, a left camera S6L that captures images of the space to the left of the construction machinery 100, a right camera S6R that captures images of the space to the right of the construction machinery 100, and a rear camera S6B that captures images of the space behind the construction machinery 100.

[0046] The spatial recognition device S6 is, for example, a monocular camera with imaging elements such as CCD or CMOS, which can output the captured images to the display device 40.

[0047] The front camera S6F is mounted, for example, on the top of the cockpit 10. The left camera S6L is mounted on the left end of the upper surface of the upper rotating body 3. The right camera S6R is mounted on the right end of the upper surface of the upper rotating body 3. The rear camera S6B is mounted on the rear end of the upper surface of the upper rotating body 3.

[0048] The spatial recognition device S6, positioned at the aforementioned location, can capture images of objects surrounding the construction machinery 100. Furthermore, the spatial recognition device S6 can be a camera (e.g., an RGBD camera or a stereo camera) capable of identifying the distance to the object being photographed. Additionally, the spatial recognition device S6 can be a LiDAR.

[0049] The positioning device PD is configured to acquire information related to the position of the construction machinery 100. In this embodiment, the positioning device PD is configured to determine the position and orientation of the construction machinery 100 in a reference coordinate system. Specifically, the positioning device PD is a GNSS (Global Navigation Satellite System) receiver equipped with an electronic compass, which determines the latitude, longitude, and altitude of the current position of the construction machinery 100, and also determines the orientation of the construction machinery 100 (upper rotating body 3). In the example shown, the reference coordinate system is the World Geodetic System. The World Geodetic System is a three-dimensional orthogonal XYZ coordinate system with the Earth's center of gravity as the origin, the direction of the intersection of the Greenwich Meridian and the equator as the X-axis, the direction of 90 degrees east longitude as the Y-axis, and the direction of the North Pole as the Z-axis.

[0050] The communication device T1 is configured to control communication with equipment located outside the construction machinery 100. In this embodiment, the communication device T1 is configured to control communication between the communication device T1 and equipment located outside the construction machinery 100 via a wireless communication network. The communication device T1 may include, for example, a mobile communication module corresponding to mobile communication standards such as LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation), or a satellite communication module for connecting to a satellite communication network.

[0051] Furthermore, the communication device T1 can be configured, for example, to control wireless communication between an external GNSS measurement system and the construction machinery 100.

[0052] Figure 3 It means Figure 2 A diagram illustrating the structure of the drive control system of construction machinery 100. Figure 3 In the diagram, the mechanical power transmission system is represented by double lines, the working oil pipeline by thick solid lines, the pilot line by dashed lines, and the electric drive / control system by dotted lines.

[0053] The drive system of the construction machinery 100 involved in this embodiment includes an engine 11, a regulator 13, a main pump 14, and a control valve unit 17. Furthermore, the hydraulic drive system of the construction machinery 100 includes a travel hydraulic motor (left travel hydraulic motor 1L and right travel hydraulic motor 1R) serving as a travel actuator DA, a slewing hydraulic motor 2A serving as a slewing actuator SA, and a boom cylinder 7, a stick cylinder 8, and a bucket cylinder 9 serving as a work actuator WA.

[0054] The regulator 13 is configured to control the output of the main pump 14. In the example shown, the regulator 13 adjusts the angle (deflection angle) of the swashplate of the main pump 14 according to control commands from the excavator controller 30.

[0055] The main pump 14, like the engine 11, is mounted on the upper rotating body 3 and supplies working oil to the control valve unit 17 via a working oil line. Furthermore, the main pump 14 is driven by the engine 11. In the example shown, the main pump 14 is a variable-capacity hydraulic pump. As described above, under the control of the excavator controller 30, the piston stroke length is adjusted by regulating the deflection angle of the swashplate via the adjuster 13, thereby controlling the discharge flow rate (discharge pressure).

[0056] Control valve unit 17 is a hydraulic control device for controlling the hydraulic system in construction machinery 100. In the example shown, control valve unit 17 includes control valves 171 to 176, which function as spool valves. Control valve unit 17 is configured to selectively supply working oil discharged from main pump 14 to one or more hydraulic actuators via control valves 171 to 176. Control valves 171 to 176, for example, control the flow rate of working oil from main pump 14 to hydraulic actuators and the flow rate of working oil from hydraulic actuators to working oil reservoirs. The hydraulic actuators include boom cylinder 7, stick cylinder 8, bucket cylinder 9, left travel hydraulic motor 1L, right travel hydraulic motor 1R, and swing hydraulic motor 2A. More specifically, control valve 171 corresponds to left travel hydraulic motor 1L, control valve 172 corresponds to right travel hydraulic motor 1R, and control valve 173 corresponds to swing hydraulic motor 2A. Furthermore, control valve 174 corresponds to bucket cylinder 9, control valve 175 corresponds to boom cylinder 7, and control valve 176 corresponds to stick cylinder 8.

[0057] The pilot pump 15 is an example of a pilot pressure generating device, and is configured to supply working oil to hydraulic control equipment via pilot lines. In this embodiment, the pilot pump 15 is a fixed-capacity hydraulic pump. However, the pilot pressure generating device can be implemented by the main pump 14. That is, in addition to supplying working oil to the control valve unit 17 via working oil lines, the main pump 14 can also supply working oil to various hydraulic control devices via pilot lines. In this case, the pilot pump 15 can be omitted.

[0058] Operating device 26 is a device for the operator OP located in the cab 10 to operate the actuators. The actuators include at least one of hydraulic actuators and electric actuators. In the example shown, operating device 26 includes a control lever, a travel lever, and a travel pedal. The control lever includes a left control lever for swing operation and stick operation, and a right control lever for boom operation and bucket operation.

[0059] The discharge pressure sensor 28 is configured to detect the discharge pressure of the main pump 14. In this embodiment, the discharge pressure sensor 28 outputs the detected value to the excavator controller 30.

[0060] The operation sensor 29 is configured to detect the operation content (OP) of the operator using the operation device 26. In this embodiment, the operation sensor 29 detects the operation direction and operation amount of the operation device 26 corresponding to each actuator and outputs the detected value to the excavator controller 30. Specifically, the operation sensor 29 may be, for example, a tilt sensor that detects the tilt angle of the operating lever or an angle sensor that detects the swing angle of the operating lever around the swing axis. The operation sensor 29 may be composed of other sensors such as pressure sensors, current sensors, voltage sensors, or distance sensors. In the example shown, the excavator controller 30 controls the opening area of ​​the solenoid valve 31 based on the output of the operation sensor 29. Furthermore, the excavator controller 30 applies pressure based on the working oil discharged by the pilot pump 15 to the pilot port of the corresponding control valve in the control valve unit 17. The pressure of the working oil acting on the pilot port (pilot pressure) is, in principle, the pressure corresponding to the operation direction and operation amount of the operation device 26 corresponding to each hydraulic actuator. Thus, the operating device 26 is configured to apply pressure based on the working oil discharged by the pilot pump 15 to the pilot port of the corresponding control valve in the control valve unit 17.

[0061] The solenoid valve 31, functioning as a control valve for equipment control, is located in the oil passage connecting the pilot pump 15 and the pilot port of the control valve within the control valve unit 17, and is configured to change the flow area of ​​this oil passage. In the illustrated example, the solenoid valve 31 operates according to a control command output by the excavator controller 30. Therefore, the excavator controller 30 can achieve the desired pilot pressure by applying the pressure of the working oil discharged from the pilot pump 15 to the pilot port of the control valve within the control valve unit 17 via the solenoid valve 31, independent of the operator's (OP) operation of the operating device 26. In the illustrated example, the excavator controller 30 is configured to perform feedback control of the pilot pressure based on the output of the pilot pressure sensor 32.

[0062] According to this structure, the excavator controller 30 can activate the hydraulic actuator corresponding to the specific operating device 26 not only when operating the specific operating device 26, but also when not operating the specific operating device 26.

[0063] Furthermore, the excavator controller 30 is configured to perform various functions in addition to controlling the pilot pressure. For example, the excavator controller 30 can set a target speed according to a working mode preset by the operator (OP) and perform drive control to keep the engine 11 rotating at a constant speed.

[0064] Furthermore, the excavator controller 30 can, for example, output control commands to the regulator 13 as needed to change the discharge volume of the main pump 14.

[0065] Furthermore, the excavator controller 30 can, for example, perform equipment guidance functions related to guiding the manual operation of the construction machinery 100 by the operator OP via the operating device 26. Also, the excavator controller 30 can, for example, perform equipment control functions related to automatically supporting the manual operation of the construction machinery 100 by the operator OP via the operating device 26.

[0066] Furthermore, the excavator controller 30 can acquire payload information based on the output of the information acquisition device IAD. In the example shown, the information acquisition device IAD includes a posture sensor AS and a cylinder pressure sensor CPS. The posture sensor AS includes a boom angle sensor S1, a stick angle sensor S2, and a bucket angle sensor S3. The cylinder pressure sensor CPS includes a boom cylinder pressure sensor S7, a stick cylinder pressure sensor S8, and a bucket cylinder pressure sensor S9. Additionally, the boom cylinder pressure sensor S7 includes a boom bottom pressure sensor S7B and a boom rod pressure sensor S7R; the stick cylinder pressure sensor S8 includes a stick bottom pressure sensor S8B and a stick rod pressure sensor S8R; and the bucket cylinder pressure sensor S9 includes a bucket bottom pressure sensor S9B and a bucket rod pressure sensor S9R. The payload information includes, for example, the weight of the sand and soil taken into the bucket 6.

[0067] Furthermore, some of the functions of the excavator controller 30 can also be implemented by other controllers (control devices). That is, the functions of the excavator controller 30 can be implemented by multiple controllers. For example, the equipment guidance function and the equipment control function can also be implemented by a dedicated controller (control device). The same applies to the function of calculating payload information.

[0068] Next, refer to Figure 4 This document describes the payload information management system (PS) that manages payload information. Figure 4This is a block diagram representing a structural example of a payload information management system (PS).

[0069] In the example shown, the payload information management system PS is configured to include an excavator controller 30, a wireless communication device 50, an information acquisition device IAD, a display device 40, and a communication device T1. The information acquisition device IAD includes an operation sensor 29, a posture sensor AS, and a cylinder pressure sensor CPS. Furthermore, the excavator controller 30 is connected to the display device 40, the wireless communication device 50, and the communication device T1 via a CAN (Controller Area Network).

[0070] The display device 40 is configured to display various information. In this embodiment, the display device 40 is configured to display one or more video images captured by the camera device, which is a spatial recognition device S6. The display device 40 operates by receiving power from a battery. The display device 40 includes a control unit 40a, an image display unit 41, and an operation unit 42.

[0071] The control unit 40a controls the image displayed on the image display unit 41. In this embodiment, the control unit 40a is configured as a computer equipped with a CPU, RAM, NVRAM, ROM, and input / output interfaces. In this case, the control unit 40a reads the software (program) corresponding to each functional component from the ROM and loads it into the RAM, causing the CPU to execute the corresponding processing. Each functional component can be configured in hardware or a combination of software and hardware. Furthermore, the image displayed on the image display unit 41 can also be controlled by the excavator controller 30 or the space recognition device S6.

[0072] The image display unit 41 displays a main screen showing a camera image captured by at least one of the camera devices, which serves as a spatial recognition device S6. The camera image may be, for example, any one of a rear image captured by the rear camera S6B, a left image captured by the left camera S6L, and a right image captured by the right camera S6R. Furthermore, the camera image may also be a top-down image obtained by combining camera images captured by the rear camera S6B, left camera S6L, and right camera S6R respectively. Additionally, the camera image may be two or more images selected from the rear image, left image, right image, and top-down image. The main screen includes status information indicating the state of the construction machinery 100 or setting information indicating various settings of the construction machinery 100.

[0073] The operation unit 42 is a switch panel that includes a hardware switch. The operation unit 42 can also be a touch panel. In the example shown, the operation unit 42 is located below the image display unit 41 and includes a button switch 42a for changing (switching) the screen or image displayed on the image display unit 41. However, the configuration of the operation unit 42 is not limited to the above example; for example, it can be configured on a joystick, or on the left or right console of the driver's seat. In addition to the operation unit 42 provided on the display device 40, a driver's seat-side operation unit with the same function as the operation unit 42 can be configured on at least one of the joystick, the left console, and the right console.

[0074] Here, for reference Figure 5 The flow of payload information exchanged between the excavator controller 30, wireless communication device 50, display device 40, management center 300, operator portable terminal device SP1, driver portable terminal device SP2, and communication device T1 is explained. Figure 5 This is a flowchart representing an example of a process for displaying payload information.

[0075] First, the operator (OP) of the construction machinery 100 enters the cab 10 of the construction machinery 100 and starts the payload information management application, which is a dedicated application (software), on the operator's portable terminal device SP1. This payload information management application is software that receives payload information from the construction machinery 100, generates an electronic ticket based on the received payload information, and sends the generated electronic ticket to the driver's portable terminal device SP2.

[0076] An electronic ticket is an electronic pass sent from the operator (OP) of construction machinery 100 to the driver (DV) of transport vehicle 200. In the example shown, the electronic ticket is generated based on payload information. Specifically, the electronic ticket is data in PDF format and is generated in a non-editable manner. However, an electronic ticket can also be data in text format.

[0077] In the example shown, when the operator (OP) first establishes a Bluetooth (trademarked) connection between the operator's portable terminal device SP1 and the wireless communication device 50, key pairing is performed. For subsequent connections, the operator (OP) does not need to enter a key; simply by bringing the operator's portable terminal device SP1 into the cockpit 10, direct wireless communication between the operator's portable terminal device SP1 and the wireless communication device 50 can be achieved.

[0078] If the payload information management application is launched, the operator sends a connection request signal to the wireless communication device 50 using a portable terminal device SP1. Upon receiving the connection request signal, the wireless communication device 50 sends device number information to the operator's portable terminal device SP1. The device number information is related to the device number of the construction machinery 100 equipped with the wireless communication device 50, and is pre-stored in the excavator controller 30, containing a device number of a specified number of characters. Furthermore, the excavator controller 30 repeatedly sends the device number information to the wireless communication device 50 at a predetermined period. Therefore, typically, the wireless communication device 50 receives the device number information from the excavator controller 30 before receiving the connection request signal.

[0079] Then, if the loading operation of the construction machinery 100 is completed, and the operator OP operates the button switch corresponding to the loading completion button image displayed on the screen of the display device 40, the display device 40 sends a payload information request signal to the excavator controller 30.

[0080] Then, the excavator controller 30, having received the payload information request signal, sends the previously unsent payload information to the wireless communication device 50 as the current payload information. The wireless communication device 50, having received the current payload information, transmits the current payload information to the operator's portable terminal device SP1. Furthermore, the current payload information refers to the payload information generated by the excavator controller 30 based on information acquired after the previous payload information was sent (information from the information acquisition device IAD), or the initial payload information in the absence of previous payload information.

[0081] Then, the payload information is displayed on the display (touch panel) of the operator's portable terminal device SP1, which receives the payload information. During this stage, the operator (OP) can generate an electronic ticket by adding various information to the payload information through touch operation on the display of the operator's portable terminal device SP1.

[0082] Then, the operator (OP) sends the generated electronic ticket to the driver's portable terminal device (SP2) by touching the part corresponding to the shared button image displayed on the display of the operator's portable terminal device (SP1).

[0083] The driver's portable terminal device SP2, upon receiving the electronic ticket, can display the electronic ticket on its display unit (touch panel). Therefore, the driver's DV of the transport vehicle 200 can easily view the payload information related to the objects loaded on the cargo box of the transport vehicle 200 being driven by the driver on the display unit of the driver's portable terminal device SP2.

[0084] Next, refer to Figure 6 An example of the structure of the image display unit 41 and the operation unit 42 of the display device 40 will be described. Figure 6 This diagram illustrates an example of the structure of the image display unit 41 and the operation unit 42 of the display device 40. Figure 6 The example shown illustrates the following state: In the image display unit 41, as a screen displayed before the button switch 42a of the operation unit 42 is operated, a main screen is displayed including the right-side image RG, the rear image BG, and the overhead image TG captured by the camera device, which is the spatial recognition device S6. The main screen is the screen displayed during the operation of the construction machinery 100.

[0085] If the designated button switch 42a in the operation unit 42 is operated while the main screen is displayed, the image display unit 41 displays other screens. For example, before and after the button switch 42a in the operation unit 42 is operated, the image display unit 41 does not change the size of the right image RG and the rear image BG, but displays other information in the area where the overhead image TG is displayed. Specifically, the image display unit 41 switches the currently displayed overhead image TG to an information image (menu display subscreen) that corresponds to the designated button switch 42a, such as a status display image (status display subscreen) indicating the status of the construction machinery 100 or a setting display image (setting display subscreen) indicating various settings of the construction machinery 100.

[0086] First, the image display unit 41 will be described. For example... Figure 6 As shown, the image display unit 41 includes a date and time display area 41a, a driving mode display area 41b, an auxiliary device display area 41c, a fuel consumption rate display area 41d, an engine control status display area 41e, an engine running time display area 41f, a coolant temperature display area 41g, a fuel balance display area 41h, a speed level display area 41i, a urea water balance display area 41j, an operating oil temperature display area 41k, an air conditioning operation status display area 41m, an image display area 41n, and a switch image display area 41p.

[0087] The walking mode display area 41b, auxiliary device display area 41c, engine control status display area 41e, speed level display area 41i, and air conditioning operation status display area 41m are areas that display information related to the setting status of the construction machinery 100, i.e., setting status information. The fuel consumption rate display area 41d, engine running time display area 41f, coolant temperature display area 41g, fuel balance display area 41h, urea water balance display area 41j, and working oil temperature display area 41k are areas that display information related to the operating status of the construction machinery 100, i.e., operating status information.

[0088] Specifically, date and time display area 41a displays the current date and time. Travel mode display area 41b displays the current travel mode. Accessory display area 41c displays an image representing the currently installed accessories. Fuel consumption rate display area 41d displays fuel consumption rate information calculated by the excavator controller 30. Fuel consumption rate display area 41d includes an average fuel consumption rate display area 41d1 displaying the total average fuel consumption rate or the interval average fuel consumption rate, and an instantaneous fuel consumption rate display area 41d2 displaying the instantaneous fuel consumption rate.

[0089] The engine control status display area 41e displays the control status of the engine 11. The engine running time display area 41f displays the cumulative running time of the engine 11. The coolant temperature display area 41g displays the current temperature of the engine coolant. The fuel level display area 41h displays the remaining fuel in the fuel tank. The speed level display area 41i displays the current speed level set by the control panel 75 graphically. Figure 6 This indicates that level 1 has been selected. The urea water level display area 41j is an area that graphically displays the remaining urea water level in the urea water tank. The working oil temperature display area 41k is an area that displays the temperature of the working oil in the working oil tank.

[0090] The air conditioner operation status display area 41m includes an air outlet display area 41m1 that displays the current air outlet position, an operation mode display area 41m2 that displays the current operation mode, a temperature display area 41m3 that displays the current set temperature, and an air volume display area 41m4 that displays the current set air volume.

[0091] Image display area 41n is the area for displaying images captured by the camera device, which functions as a spatial recognition device S6. Figure 6In the example shown, image display area 41n displays the right image RG, the rear image BG, and the overhead image TG. The right image RG shows the space to the right of the construction machinery 100 and includes the image GC1 of the right end of the upper surface of the upper rotating body 3. The right image RG is an actual viewpoint image generated by the control unit 40a, based on the image acquired by the right camera S6R. The rear image BG shows the space behind the construction machinery 100 and includes the image GC2 of the counterweight. The rear image BG is an actual viewpoint image generated by the control unit 40a and based on the image acquired by the rear camera S6B. The overhead image TG is a virtual viewpoint image generated by the control unit 40a and based on the images acquired by the rear camera S6B, the left camera S6L, and the right camera S6R, respectively. Furthermore, an excavator graphic corresponding to the construction machinery 100 is placed in the central part of the overhead image. This is to allow the operator (OP) to intuitively grasp the positional relationship between the construction machinery 100 and objects existing around it.

[0092] Furthermore, the image display area 41n has a first image display area 41n1 located above and a second image display area 41n2 located below. Figure 6 In the example shown, the right image RG and the rear image BG are configured in the first image display area 41n1, and the top-view image TG is configured in the second image display area 41n2. Alternatively, in the image display area 41n, the top-view image TG can also be configured in the first image display area 41n1, and the rear image BG and the right image RG can be configured in the second image display area 41n2.

[0093] Furthermore, the image display area 41n can also be configured to simultaneously display the left image. In this case, the left image and the right image RG can be arranged in the first image display area 41n1, and the rear image BG and the top-view image TG can be arranged in the second image display area 41n2. In this case, the left image can be arranged to the left of the first image display area 41n1 and the right image RG can be arranged to the right of the first image display area 41n1.

[0094] Furthermore, in Figure 6 In the example shown, the right image RG and the rear image BG are arranged adjacently, but they can also be arranged with an interval between them. Furthermore, in Figure 6In the example shown, the image display area 41n is a vertically elongated area, but it can also be a horizontally elongated area. When the image display area 41n is horizontally elongated, a top-view image TG can be configured on the left as the first image display area 41n1, and a rear image BG and a right image RG can be configured on the right as the second image display area 41n2. In this case, the left and right images can be arranged alternately, or the positions of the top-view image TG and the rear image BG and right image RG can be interchanged.

[0095] The switch image display area 41p includes the first switch image display area 41p1 to the seventh switch image display area 41p7. Figure 6 In the example shown, at the bottom of the image display unit 41, the first switch image display area 41p1 to the seventh switch image display area 41p7 are arranged with intervals between them. Icons representing the functions of the corresponding button switches 42a1 to 42a7 are displayed in the first switch image display area 41p1 to the seventh switch image display area 41p7.

[0096] The first switch image display area 41p1 displays icons for displaying detailed menu items. If the operator (OP) operates the button switch 42a1 corresponding to the first switch image display area 41p1, the icons displayed in the second switch image display areas 41p2 to the seventh switch image display areas 41p7 are switched to icons associated with the detailed menu items.

[0097] exist Figure 6 In the example shown, an icon for displaying information related to the digital level is displayed in the fourth switch image display area 41p4. If the operator (OP) operates the button switch 42a4 corresponding to the fourth switch image display area 41p4, the overhead image TG displayed in the second image display area 41n2 switches to an image (sub-screen) displaying information related to the digital level. On the other hand, the rear image BG and right image RG displayed in the first image display area 41n1 continue to be displayed at the same size. However, the image (sub-screen) displaying information related to the digital level can also be displayed in the first image display area 41n1. In this case, the rear image BG and right image RG displayed in the first image display area 41n1 can also be displayed in the second image display area 41n2 instead of the overhead image TG.

[0098] The sixth switch image display area 41p6 displays icons for displaying information related to information-based construction. If the operator (OP) operates the button switch 42a6 corresponding to the sixth switch image display area 41p6, the overhead image TG displayed in the second image display area 41n2 switches to an image (sub-screen) representing information related to information-based construction. On the other hand, the rear image BG and right image RG displayed in the first image display area 41n1 continue to be displayed at the same size. However, the image (sub-screen) representing information related to information-based construction can also be displayed in the first image display area 41n1. In this case, the rear image BG and right image RG displayed in the first image display area 41n1 can also be displayed in the second image display area 41n2 instead of the overhead image TG.

[0099] The 7th switch image display area 41p7 displays icons for showing information related to the crane mode. If the operator (OP) operates the push-button switch 42a7 corresponding to the 7th switch image display area 41p7, the overhead image TG displayed in the 2nd image display area 41n2 switches to an image (sub-screen) showing information related to the crane mode. On the other hand, the rear image BG and right image RG displayed in the 1st image display area 41n1 continue to be displayed at the same size. However, the image (sub-screen) showing information related to the crane mode can also be displayed in the 1st image display area 41n1. In this case, the rear image BG and right image RG displayed in the 1st image display area 41n1 can also be displayed in the 2nd image display area 41n2 instead of the overhead image TG.

[0100] exist Figure 6 In the example shown, no icons are displayed in the second switch image display area 41p2, the third switch image display area 41p3, and the fifth switch image display area 41p5. Therefore, even if the operator operates the button switches 42a2, 42a3, and 42a5 corresponding to the second switch image display area 41p2, the third switch image display area 41p3, and the fifth switch image display area 41p5, the images displayed on the image display unit 41 will not change.

[0101] In addition, the icons displayed in the first switch image display area 41p1 to the seventh switch image display area 41p7 are not limited to the examples described above, and icons used to display other information may also be displayed.

[0102] Next, the operation unit 42 will be explained. For example... Figure 6 As shown, the operation unit 42 is composed of push-button switches 42a, which correspond to the first switch image display area 41p1 to the seventh switch image display area 41p7 respectively. Figure 6In the example shown, the operation unit 42 includes seven push-button switches 42a1 to 42a7 disposed in the upper section and seven push-button switches 42a8 to 42a14 disposed in the lower section. Push-button switches 42a8 to 42a14 are disposed below each of the push-button switches 42a1 to 42a7. However, the number, shape, and arrangement of the push-button switches 42a in the operation unit 42 are not limited to the above example; for example, they could be arranged in a manner that combines the functions of multiple push-button switches into one, such as a micro-roller or micro-switch. Furthermore, the operation unit 42 can be configured as a component different from the display device 40. It can also be operated by directly touching the first switch image display area 41p1 to the seventh switch image display area 41p7 using a touch panel that integrates the image display unit 41 and the operation unit 42.

[0103] Button switches 42a1 to 42a7 are positioned below the first to seventh switch image display areas 41p1 to 41p7, respectively, and function as button switches for selecting each of these areas. Because button switches 42a1 to 42a7 are positioned below the first to seventh switch image display areas 41p1 to 41p7, respectively, the operator can intuitively select each of these areas.

[0104] The button switch 42a8 is used to switch the camera image displayed in the image display area 41n. It is configured such that, each time the button switch 42a8 is operated, the camera image displayed in the first image display area 41n1 of the image display area 41n is switched between, for example, a rear image, a left image, a right image, and a top-down image. It can also be configured such that, each time the button switch 42a8 is operated, the camera image displayed in the second image display area 41n2 of the image display area 41n is switched between, for example, a rear image, a left image, a right image, and a top-down image. Furthermore, it can also be configured such that, each time the button switch 42a8 is operated, the camera image displayed in the first image display area 41n1 and the camera image displayed in the second image display area 41n2 of the image display area 41n are interchanged. Thus, the button switch 42a8, which serves as the operation unit 42, can be used to switch between the camera images displayed in the first image display area 41n1 and the second image display area 41n2, and can also be used to switch between the camera images displayed in the first image display area 41n1 and the camera images displayed in the second image display area 41n2. Furthermore, a separate switch for switching the image displayed in the second image display area 41n2 can also be provided.

[0105] Push-button switches 42a9 and 42a10 are used to adjust the air conditioner's fan speed. Figure 6 In the example shown, if button switch 42a9 is operated, the air volume of the air conditioner decreases, and if button switch 42a10 is operated, the air volume of the air conditioner increases.

[0106] The push-button switch 42a11 is used to switch the cooling / heating function on / off. Figure 6 In the example shown, the cooling / heating function is switched on / off each time the button switch 42a11 is operated.

[0107] Push-button switches 42a12 and 42a13 are used to adjust the set temperature of the air conditioner. Figure 6 In the example shown, if button switch 42a12 is operated, the set temperature will decrease, and if button switch 42a13 is operated, the set temperature will increase.

[0108] The push-button switch 42a14 is a switch that can switch the display of the engine running time display area 41f.

[0109] Furthermore, push-button switches 42a2-42a6 and 42a9-42a13 are configured to input numbers displayed on or near the switches. Additionally, push-button switches 42a3, 42a4, 42a5, and 42a11 are configured to move the cursor left, up, right, and down respectively when the cursor is displayed in the image display area 41n.

[0110] In addition, the functions assigned to the aforementioned push-button switches 42a1~42a7 and 42a8~42a14 are just one example; other functions can also be assigned.

[0111] As described above, if the button switch 42a1 corresponding to the first switch image display area 41p1 is operated while the right image RG, the rear image BG, and the overhead image TG are displayed in the image display area 41n, then new icons (indicating the functions newly assigned to the button switches 42a1 to 42a7) will be displayed in the second switch image display area 41p2 to the seventh switch image display area 41p7 while the right image RG and the rear image BG are displayed. Therefore, the operator (OP) can confirm the right image RG and the rear image BG while simultaneously confirming the new icons.

[0112] Furthermore, in the above example, if one of the push-button switches 42a1 to 42a7 corresponding to the first switch image display area 41p1 to the seventh switch image display area 41p7 is operated while the right image RG, the rear image BG, and the overhead image TG are displayed in the image display area 41n, the overhead image TG will switch to an information image displaying information corresponding to the selected switch image display area 41p. Thus, by displaying the information image while the right image RG and the rear image BG are displayed, the operator (OP) can continue to monitor the surroundings (rear and right spaces) even when the information image is displayed. Therefore, the operator (OP) can operate the construction machinery 100 while the information image is displayed.

[0113] Next, refer to Figure 7 An example of displaying an information image on the image display unit 41 of the display device 40 will be described. Figure 7 This is a diagram showing a screen including, for example, a payload information image 41q, which is an information image displayed on the image display unit 41 of the display device 40. For example, in the switch image display area 41p (not shown),... Figure 6 When the button switch 42a corresponding to one of the first switch image display areas 41p1 to the seventh switch image display areas 41p7 is respectively displayed, the information is displayed in the image display area. Figure 7 The payload information image 41q is displayed in the image display unit 41.

[0114] exist Figure 7 In the example shown, the first switch image display area 41p1 displays menu detail item icons for displaying menu details. If the operator (OP) operates the button switch 42a1 corresponding to the first switch image display area 41p1, the icons displayed in the second switch image display areas 41p2 to the seventh switch image display areas 41p7 are switched to icons associated with the menu detail items.

[0115] The second switch image display area 41p2 displays an icon (the cargo box icon of the transport vehicle 200) for displaying a screen that shows information related to the transport vehicle 200. If the operator (OP) operates the push-button switch 42a2 corresponding to the second switch image display area 41p2, a screen for setting information related to the transport vehicle 200 will be displayed on the image display unit 41. The information related to the transport vehicle 200 includes the maximum load weight, etc.

[0116] The third switch image display area 41p3 displays an icon (target icon) for setting the target load weight. If the operator operates the button switch 42a3 corresponding to the third switch image display area 41p3, the image display unit 41 will display the screen for setting the target load weight.

[0117] The fourth switch image display area 41p4 displays an icon (an icon of two vertically extending lines) indicating that the calculation of the weight of the object taken into the bucket 6 is temporarily interrupted. If the operator (OP) operates the button switch 42a4 corresponding to the fourth switch image display area 41p4, a text message indicating that the calculation related to the weight of the object taken into the bucket 6 has been interrupted will be displayed on the image display unit 41. During this period, regardless of where the object taken into the bucket 6 is dumped (unloaded) (including the cargo box of the transport vehicle 200), its weight will not be added to the loading weight (the weight of the object loaded on the cargo box of the transport vehicle 200). Furthermore, if the operator (OP) operates the button switch 42a4 again, the interruption will be lifted.

[0118] The fifth switch image display area 41p5 displays an icon (× mark icon) indicating that the weight of the object currently being loaded into the bucket 6 is not being calculated. If the operator (OP) operates the button switch 42a5 corresponding to the fifth switch image display area 41p5, a text message indicating that the weight of the object currently loaded into the bucket 6 is not being calculated will be displayed on the image display unit 41. At this time, regardless of where the object currently loaded into the bucket 6 is dumped (unloaded) (including the cargo box of the transport vehicle 200), the weight of the object currently loaded into the bucket 6 will not be added to the loading weight.

[0119] The sixth switch image display area 41p6 displays an icon (a checkmark icon) to inform the excavator controller 30 that the loading operation has been completed. If the operator (OP) operates the button switch 42a6 corresponding to the sixth switch image display area 41p6, a payload information request signal is sent from the display device 40 to the excavator controller 30, and a text message indicating that the loading operation has been completed is displayed on the image display unit 41. Therefore, the button switch 42a6 functions as a "loading complete button".

[0120] An icon (power indicator icon) for accessing the main screen is displayed in the 7th switch image display area 41p7. If the operator (OP) operates the button switch 42a7 corresponding to the 7th switch image display area 41p7, the image display section 41 will display an icon (power indicator icon) for accessing the main screen. Figure 6 The main screen shown.

[0121] Furthermore, in Figure 7 In the example shown, the payload information image 41q includes a truck icon 41q1, a target loaded weight image 41q2, a bucket load image 41q3, a bucket internal load image 41q4, a bucket icon 41q5, a truck name image 41q6, a bucket name image 41q7, a unit of measurement image 41q8, a cloud icon 41q9, a zero point adjustment icon 41q10, a truck counter image 41q11, and a bucket counter image 41q12.

[0122] Truck icon 41q1 is an icon representing the loading status of objects loaded on the cargo box of transport vehicle 200. In the example image, truck icon 41q1 is configured to represent the loading status of transport vehicle 200 in six stages: "empty", "small quantity", "medium", "almost fully loaded", "fully loaded" and "overloaded" by changing the size of the image portion representing the objects loaded on the cargo box. Figure 7 This indicates a "medium" loading status. Furthermore, the truck icon 41q1 can be configured to turn off if the loading operation is interrupted.

[0123] Image 41q2 represents the target load weight of objects loaded onto the cargo box of transport vehicle 200. In the example image, the initial value of the target load weight is the maximum load weight of transport vehicle 200, and the target load weight decreases as objects are loaded onto the cargo box of transport vehicle 200. Furthermore, the display color of the target load weight can change according to the loading status, etc.

[0124] Image 41q3 shows the weight of objects loaded onto the cargo box of transport vehicle 200, i.e., the load inside the truck bed. Similar to the target load weight, the display color of the load inside the truck bed can change depending on the loading status, etc. In this case, the loading status can be determined based on the ratio of the load inside the truck bed to the maximum load weight.

[0125] Image 41q4 shows the weight of the object that has been loaded into bucket 6, i.e., the load inside the bucket. Similar to the target load weight and the load inside the bucket, the display color of the load inside the bucket can change depending on the loading status. In this case, the loading status can be determined based on the ratio of the total weight of the load inside the bucket and the weight inside the bucket to the maximum load weight.

[0126] Figure 7 This indicates a target load weight of 0.5 tons and a bed load of 9.5 tons. This is based on the fact that the maximum load weight of transport vehicle 200 is 10 tons. Furthermore, Figure 7 This indicates a situation where the load inside the bucket is 0.8 tons, exceeding the target loading weight. That is, Figure 7This indicates a situation where, if all the objects in the bucket 6 are loaded onto the cargo box of the transport vehicle 200, the combined weight of the load in the bucket and the load in the cargo box exceeds the maximum load capacity of the transport vehicle 200.

[0127] The bucket icon 41q5 is an icon that indicates the state of the bucket 6. In the example diagram, the bucket icon 41q5 is configured to represent the loading state of the bucket 6 in three stages: "with soil (measurement accuracy: normal)", "with soil (measurement accuracy: low)" and "without soil" by changing the size of the image portion (area of ​​the lit portion) representing the object being taken into the bucket 6. Figure 7 This indicates the loading status as "with soil (measurement accuracy: normal)". Furthermore, the bucket icon 41q5 can be configured to turn off if the loading operation is interrupted.

[0128] Truck name image 41q6 is an image representing the name of the transport vehicle 200 that is the object of the loading operation. Figure 7 In the image 41q6, the truck name image, together with the icon representing the cargo box of the transport vehicle 200, indicates that the name of the transport vehicle 200, which is the object of the loading operation, is "DP-001".

[0130] Image 41q8 is an image representing the units of measurement for the displayed loads (weights). In the example image, the unit is selected from "t" (tons) or "lb" (pounds). Figure 7 The unit is "t" (ton).

[0131] The cloud icon 41q9 indicates the connection status with the server (management center 300). In the example diagram, the cloud icon 41q9 is configured such that by changing the icon's color, operators can distinguish between "currently communicating with the server" and "not communicating with the server". Figure 7 This indicates a state of "communicating with the server".

[0132] The zero-point adjustment icon 41q10 indicates the implementation status of zero-point adjustment. In the example diagram, the zero-point adjustment icon 41q10 is configured such that, by changing the icon's color, the operator (OP) can distinguish between "no zero-point adjustment" and "zero-point adjustment implemented." Zero-point adjustment is an adjustment performed when the load inside the bucket 6 is a value other than zero, even though no object has been retrieved. Furthermore, "zero-point adjustment implemented" indicates, for example, that when the load inside the bucket 6 is a value other than zero, even though no object has been retrieved, the auxiliary device is set to a predetermined position and a predetermined reset button is pressed (resulting in the bucket load being adjusted to zero). Figure 7 This indicates a state where "zero point adjustment has been implemented." Furthermore, the "zero point adjustment implemented" state can be valid for only one subsequent loading operation, or it can remain valid for multiple subsequent loading operations. If it's only valid for one subsequent loading operation, the "zero point adjustment implemented" state can automatically switch to a "zero point adjustment not implemented" state at the moment of dumping (unloading).

[0133] Truck counter image 41q11 is an image representing the number of transport vehicles 200 that have been loaded. In the example image, truck counter image 41q11 represents the number of transport vehicles 200 that have been loaded after the payload information management application has been launched. Figure 7 The term 200 indicates that one transport vehicle has completed loading, while the term 200 indicates that the transport vehicle currently being loaded is the second transport vehicle.

[0134] Bucket counter image 41q12 is an image representing how many times the transport vehicle 200, which is the object of the current loading operation, has been loaded using the bucket 6. In the example image, bucket counter image 41q12 indicates that the transport vehicle 200, which is the object of the current loading operation, has been loaded 4 times.

[0164] Next, refer to Figure 11 Another example of the screen displayed on the display unit (touch panel) of the operator's portable terminal device SP1 will be described. Figure 11 This is a diagram illustrating an example of the structure of the report screen SC3 displayed on the display unit (touch panel) of the operator's portable terminal device SP1.

[0165] Report screen SC3 is used to display statistical values ​​based on the acquired payload information. In the example image, in the history screen SC1 (reference) Figure 8 (or the electronic ticket generation screen SC2 (see reference)) Figure 9 When the software button SB4 is touched, the report screen SC3 is displayed.

[0166] Specifically, the report screen SC3 includes the screen icon display area GP4, the extraction condition selection area GP6, the statistical results display area GP7, the time-varying display area GP8, and the map display area GP9.

[0167] and Figure 8 The historical record screen SC1 shown is as follows Figure 9 Similarly, the screen icon display area GP4 in each of the electronic ticket generation screens shown is used to display icons related to the selectable screens. In the example image, the screen icon display area GP4 displays: SC1, representing the history screen (see reference). Figure 8 The system includes a software button SB3 for the currently displayed report screen SC3, a software button SB4 for the report screen SC3, and a software button SB5 for the settings screen (not shown). Furthermore, the software button SB4, which indicates the currently displayed report screen SC3, is distinguishably displayed from the software buttons SB3 and SB5, which are not currently displayed. In the example shown, software button SB4 is displayed in a different color than software buttons SB3 and SB5. That is, apart from the distinguishable display of software button SB4, the icon display area GP4 of the report screen SC3 is the same as the icon display area GP4 of the history screen SC1.

[0168] The extraction criteria selection area GP6 is used to select statistics by day, week, and month. In the example image, a software button SB21 is displayed in the extraction criteria selection area GP6. Software button SB21 consists of three areas: a left area with a title corresponding to the daily statistics ("Day"), a central area with a title corresponding to the weekly statistics ("Week"), and a right area with a title corresponding to the monthly statistics ("Month"). The operator (OP) can select daily statistics by touching the left area of ​​software button SB21, select weekly statistics by touching the central area, and select monthly statistics by touching the right area. Figure 11 This indicates that the statistics were selected in daily units and "Nov01,2023" (November 1, 2023) was selected.

[0169] Furthermore, the extraction condition selection area GP6 displays a software button SB22 for adjusting the selected date and time forward, and a software button SB23 for adjusting the selected date and time backward. Figure 11 In the example shown, the operator (OP) can change the selected "Nov 01, 2023" (November 1, 2023) to "Oct 31, 2023" (October 31, 2023) by touching the software button SB22 once, and can change the selected "Nov 01, 2023" (November 1, 2023) to "Nov 02, 2023" (November 2, 2023) by touching the software button SB23 once. Furthermore, when weekly statistics are selected, touching the software button SB22 changes the selected week to the previous week; when monthly statistics are selected, touching the software button SB22 changes the selected month to the previous month. The same applies to touching the software button SB23.

[0170] The statistical results display area GP7 shows a general structure of the statistical results. Figure 11 In the example shown, the statistical results in area GP7 show that the total load weight on "Nov 01, 2023" (November 1, 2023) is "240" tons, the load weight per load (bucket full) is "1.0" ton, the number of transport vehicles 200 that are the objects of the loading operation is "24", the number of dumping (unloading) required to load one transport vehicle 200 is "10", the load weight per hour is "40" tons, and the time required for each loading operation is "50" seconds.

[0171] The GP8 display area shows how various physical quantities change over time. Figure 11 In the example shown, the time-varying display area GP8 displays a two-dimensional chart showing the change of loaded weight (tons) over time. Specifically, the time-varying display area GP8 displays a bar chart with the vertical axis set to loaded weight (tons) and the horizontal axis set to time. Additionally, Figure 11 The height (value) of the bar chart shown is for illustrative purposes only and does not correspond to the values ​​displayed in the statistical results display area GP7.

[0172] The location of the loading operation site on the map is shown in map display area GP9. Figure 11The map is displayed in the map display area GP9, showing the upper part of the map, and the location where loading operations were carried out on "Nov 01, 2023" (November 1, 2023) is indicated by a circle marker CL on the map. Additionally, the operator (OP) can visually identify the remaining portion of the map (located in a larger area than the map shown in the image) by scrolling down the report screen SC3. Figure 11 (The lower part of the upper end that is visible in the middle).

[0173] Furthermore, software buttons SB10 and SB12 are displayed on the report screen SC3.

[0174] Software button SB10 is a sharing button used to share information between the operator's portable terminal device SP1 and the driver's portable terminal device SP2. The operator (OP) can access PDF format reports by touching the sharing button. Figure 11 The content displayed in the document is sent to the driver's portable terminal device SP2.

In other words, this structure enables the operators (OP) and drivers (DV) to quickly confirm more detailed information related to the objects loaded on the cargo container of the transport vehicle 200.

[0182] Furthermore, the wireless communication device 50, which is a communication device, can send payload information to a server located at a remote location (the server set up in the management center 300).

[0183] This structure has the following effect: Payload information is managed in the management center 300. Therefore, this structure has the following effect: relevant personnel, including operators (OPs) and drivers (DVs), can confirm payload information from any location at any time.

[0184] Furthermore, the payload information may include an information identification number. The payload information received by the transport vehicle 200 and the payload information received by the server (located in the management center 300) can be verified based on this information identification number.

[0185] The structure has the following effect: it can interface the payload information received by the transport vehicle 200 with the payload information received by the server (the server set up in the management center 300) to confirm the matching, thus improving the traceability of objects loaded on the cargo box of the transport vehicle 200.

[0186] Furthermore, the portable terminal device (operator's portable terminal device SP1) is a multi-functional terminal, such as a smartphone, carried by the operator OP of the construction machinery 100, and has a display section capable of displaying various information.

[0192] Furthermore, the portable terminal device (operator portable terminal device SP1) and other portable terminal devices (driver portable terminal device SP2) can be configured to communicate without pairing.

[0193] This architecture offers the following advantages: it eliminates the need for establishing and implementing wireless communication between the operator's portable terminal device SP1 and the driver's portable terminal device SP2, facilitating the easier transmission of payload information from the operator (OP) to the driver's (DV). Specifically, the operator (OP) can send electronic tickets (electronic passes) to the driver's portable terminal device SP2 simply by touching the share button on the operator's portable terminal device SP1 (smartphone) without needing to perform pairing or other preparatory operations. Furthermore, the driver's (DV) can receive electronic tickets (electronic passes) simply by holding the driver's portable terminal device SP2 (smartphone) without needing to perform pairing or other preparatory operations.

[0194] Furthermore, the portable terminal device for construction machinery involved in the embodiments of the present invention is a portable terminal device (operator portable terminal device SP1) carried by the operator OP of the construction machinery 100. It is configured to receive payload information sent from a communication device (wireless communication device 50), generate an electronic ticket based on the received payload information, and send the electronic ticket to the transport vehicle 200 via wireless communication.
