[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to the drawings. Fig. 1 is a schematic diagram showing an example of an information communication system for a construction machine.

[0011] The construction machine support system SYS of this embodiment includes a shovel 100 and a management device 300. In the construction machine support system SYS, the shovel 100 and the management device 300 communicate with each other via a network, and the management device 300 manages the shovel 100. In the following description, the construction machine support system SYS will be referred to as the support system SYS.

[0012] Furthermore, the management device 300 of this embodiment communicates with the support device 400, the terminal device 500, and the like via a network.

[0013] The shovel 100 of this embodiment is an example of a construction machine. The shovel 100 may be managed by a construction company that performs work using construction machines.

[0014] The excavator 100 comprises a lower running body 1, an upper rotating body 3 mounted on the lower running body 1 so as to be rotatable via a rotating mechanism 2, a boom 4, an arm 5, and a bucket 6 as attachments (working devices), and a cabin 10.

[0015] The lower traveling body 1 includes, for example, a pair of left and right crawlers, and is self-propelled by the crawlers being hydraulically driven by traveling hydraulic motors 1A, 1B (see FIG. 2).

[0016] The upper swing structure 3 swings relative to the lower traveling structure 1 by being driven by a swing hydraulic motor 2A (see FIG. 2).

[0017] The boom 4 is pivotally attached to the front center of the upper rotating body 3 so as to be able to tilt up and down, and an arm 5 is pivotally attached to the tip of the boom 4 so as to be able to rotate up and down, and a bucket 6 is pivotally attached to the tip of the arm 5 so as to be able to rotate up and down. The boom 4, arm 5, and bucket 6 are hydraulically driven by a boom cylinder 7, an arm cylinder 8, and a bucket cylinder 9, respectively.

[0018] The cabin 10 is a control room in which an operator (worker) rides, and is mounted on the front left side of the upper rotating body 3.

[0019] The shovel 100 can communicate with the management device 300 via a predetermined communication network NW, including, for example, a mobile communication network ending at a base station, a satellite communication network using communication satellites in the sky, the Internet, etc.

[0020] Furthermore, the excavator 100 of this embodiment acquires its own operation information and transmits it to the management device 300 periodically.

[0021] Specifically, the operation information of the shovel 100 includes position information indicating the current position of the shovel, orientation information indicating the orientation of the shovel, attitude information indicating the attitude of the shovel, performance information indicating the performance of work, load rate information indicating the load rate, accumulated time information indicating the accumulated operating time, fuel information including the amount of fuel injection, CO2 emissions, work volume, etc. Note that the position information does not have to be included in the operation information, and the position information and the operation information may be transmitted from the shovel 100 to the management device 300 separately.

[0022] Operation information includes performance information regarding work patterns for a specific type of work (e.g., repetitive work such as excavation work, loading work, finishing work, etc.) (hereinafter referred to as "work pattern performance information") and performance information regarding the environmental conditions during the work (hereinafter referred to as "environmental condition performance information").

[0023] The work pattern refers to the type of a series of operations of the shovel 100 when performing a predetermined type of work. For example, the work pattern includes the movement trajectories of operation elements such as the lower traveling structure 1, the upper rotating structure 3, the boom 4, the arm 5, and the bucket 6 during work. The work pattern performance information is specifically information detected by various sensors that indicates the performance of the work pattern of the shovel 100 when the shovel 100 actually performs a predetermined type of work. The environmental conditions may include external environmental conditions such as conditions related to the environment around the shovel 100, as well as internal environmental conditions such as variable specifications of the shovel 100 that affect the operation of the shovel 100 (for example, arm length, bucket type, etc.).

[0024] In the support system SYS of this embodiment, when the management device 300 receives operation information from the shovels 100, it identifies the shovels 100 that are present within a predetermined range based on the position information of the shovels 100 included in the operation information. Next, the management device 300 determines whether or not there is any shovel 100 that requires maintenance (repair), based on the operation information of each identified shovel 100.

[0025] Then, if there is an excavator 100 that has been determined to require maintenance, the management device 300 notifies the support device 400 to that effect.

[0026] The "predetermined range" in this embodiment may be, for example, a range that includes the location of a parking lot of a branch of a rental company that rents (dispatches) construction machines to various work sites. Also, the branch of the rental company in this embodiment is a manager that manages the parking lots located within the predetermined range and the construction machines it owns.

[0027] The support device 400 of this embodiment may be a mobile terminal carried by a serviceman belonging to a branch office. Specifically, the support device 400 is, for example, a smartphone. The serviceman is a mechanic who mainly visits parking lots to perform maintenance on construction machines such as the excavator 100.

[0028] That is, the management device 300 of this embodiment identifies the shovels 100 that have returned to the parking lot of the rental company's branch office, and further identifies the shovels 100 that require maintenance from the identified shovels 100. Then, the management device 300 notifies the support device 400 of the serviceman belonging to this branch office that there is an shovel 100 that requires maintenance among the shovels 100 that have returned to the parking lot.

[0029] Therefore, according to this embodiment, it is possible to notify the service person of the shovels 100 that need maintenance among the shovels 100 that have returned to the parking lot. In other words, according to this embodiment, it is possible to make the service person aware of the timing for maintenance of the shovel 100.

[0030] The terminal device 500 of this embodiment is, for example, a branch terminal installed at a branch of a rental company. In other words, the terminal device 500 is a terminal device for managing parking areas located within a predetermined range and the owned construction machines.

[0031] The terminal device 500 may share a schedule, such as a maintenance date, with a service technician who owns the support device 400 via the management device 300. In the following description, the terminal device 500 may be referred to as a branch terminal 500. Furthermore, the terminal device 500 may be a terminal at a service base where a service technician is on standby.

[0032] 1, the support system SYS includes one shovel 100, but this is not limiting. The number of shovels 100 included in the support system SYS may be any number, and all shovels 100 that can communicate with the management device 300 may be included in the support system SYS.

[0033] Furthermore, the management device 300 of this embodiment is a terminal device installed in a location geographically separated from the shovel 100. The management device 300 is installed, for example, in a management center or the like located outside the work site where the shovel 100 works, and is a server device configured mainly with one or more server computers or the like. In this case, the server device may be an in-house server operated by the business operator that operates the support system SYS or an associated business operator related to that business operator, or it may be a cloud server.

[0034] Next, the support system SYS of this embodiment will be further described with reference to Fig. 2. Fig. 2 is a configuration diagram showing an example of a support system for a construction machine.

[0035] In the diagram, mechanical power lines are indicated by double lines, high-pressure hydraulic lines by thick solid lines, pilot lines by dashed lines, and electric drive and control lines by thin solid lines.

[0036] The hydraulic drive system that hydraulically drives the hydraulic actuators of the excavator 100 of this embodiment includes the engine 11, the main pump 14, a regulator 14a, and a control valve 17. As described above, the hydraulic drive system of the excavator 100 also includes hydraulic actuators such as traveling hydraulic motors 1A and 1B, swing hydraulic motor 2A, boom cylinder 7, arm cylinder 8, and bucket cylinder 9 that hydraulically drive the lower traveling structure 1, upper rotating structure 3, boom 4, arm 5, and bucket 6, respectively.

[0037] The engine 11 is an example of a main power source in a hydraulic drive system, and is mounted, for example, at the rear of the upper rotating body 3. Specifically, the engine 11 rotates at a constant speed at a preset target speed under the control of an engine control unit (ECU) 74 (described later), and drives the main pump 14 and the pilot pump 15. The engine 11 is, for example, a diesel engine that uses diesel as fuel. Note that an electric motor may be used as the main power source instead of an engine. In this case, a battery is also mounted as an electricity storage device to supply power to the electric motor.

[0038] The regulator 14a controls the discharge amount of the main pump 14. For example, the regulator 14a adjusts the angle (tilt angle) of the swash plate of the main pump 14 in response to a control command from the controller 30.

[0039] The main pump 14 is mounted on the rear of the upper rotating body 3, for example, similar to the engine 11, and supplies hydraulic oil to the control valve 17 through a high-pressure hydraulic line 16. As described above, the main pump 14 is driven by the engine 11. The main pump 14 is, for example, a variable displacement hydraulic pump, and as described above, under the control of the controller 30, the tilt angle of the swash plate is adjusted by the regulator 14a, thereby adjusting the stroke length of the piston and controlling the discharge flow rate (discharge pressure).

[0040] The control valve 17 is a hydraulic control device that is mounted, for example, in the center of the upper rotating body 3 and controls the hydraulic drive system in response to an operator's operation of the control device 26. As described above, the control valve 17 is connected to the main pump 14 via the high-pressure hydraulic line 16, and selectively supplies hydraulic oil supplied from the main pump 14 to the hydraulic actuators (travel hydraulic motors 1A, 1B, swing hydraulic motor 2A, boom cylinder 7, arm cylinder 8, and bucket cylinder 9) in response to the operating state of the control device 26. Specifically, the control valve 17 includes a plurality of control valves that control the flow rate and flow direction of hydraulic oil supplied from the main pump 14 to each of the hydraulic actuators.

[0041] For example, the control valve 17 includes a control valve corresponding to the boom 4 (boom cylinder 7). Also, for example, the control valve 17 includes a control valve corresponding to the arm 5 (arm cylinder 8). Also, for example, the control valve 17 includes a control valve corresponding to the bucket 6 (bucket cylinder 9). Also, for example, the control valve 17 includes a control valve corresponding to the upper swing structure 3 (swing hydraulic motor 2A). Also, for example, the control valve 17 includes a right travel control valve and a left travel control valve corresponding to the right crawler and the left crawler of the undercarriage 1, respectively.

[0042] The operating system of the excavator 100 according to this embodiment includes a pilot pump 15, an operating device 26, and an operating valve 31.

[0043] The pilot pump 15 is mounted, for example, on the rear of the upper rotating body 3, and supplies pilot pressure to the operating device 26 and the operating valve 31 via a pilot line 25. The pilot pump 15 is, for example, a fixed displacement hydraulic pump, and is driven by the engine 11 as described above.

[0044] The operation device 26 is provided near the operator's seat in the cabin 10, and is an operation input means for the operator to operate the various operating elements (undercarriage 1, upper rotating body 3, boom 4, arm 5, bucket 6, etc.). In other words, the operation device 26 is an operation input means for the operator to operate the hydraulic actuators that drive the respective operating elements (i.e., traveling hydraulic motors 1A, 1B, swing hydraulic motor 2A, boom cylinder 7, arm cylinder 8, bucket cylinder 9, etc.).

[0045] The operation device 26 has a secondary pilot line connected to the control valve 17. As a result, a pilot pressure according to the operation state of the undercarriage 1, the upper rotating body 3, the boom 4, the arm 5, the bucket 6, etc. in the operation device 26 may be input to the control valve 17. Therefore, the control valve 17 can drive each hydraulic actuator according to the operation state of the operation device 26.

[0046] The operating valve 31 adjusts the flow path area of ​​the pilot line 25 in response to a control command (for example, a control current) from the controller 30. As a result, the operating valve 31 can output a pilot pressure corresponding to the control command to the secondary pilot line using the primary pilot pressure supplied from the pilot pump 15 as the source pressure.

[0047] The operating valve 31 has its secondary port connected to the left and right pilot ports of the control valve corresponding to each hydraulic actuator of the control valve 17, and applies pilot pressure according to a control command from the controller 30 to the pilot ports of the control valve.

[0048] As a result, even if the operating device 26 is not operated by the operator, the controller 30 can supply the hydraulic oil discharged from the pilot pump 15 to the pilot port of the corresponding control valve in the control valve 17 via the operating valve 31, thereby operating the hydraulic actuator.

[0049] In addition to the operation valve 31, an electromagnetic relief valve may be provided to relieve excess hydraulic pressure generated in the hydraulic actuator to a hydraulic oil tank. This makes it possible to actively suppress the operation of the hydraulic actuator when, for example, the operator operates the operation device 26 excessively. For example, an electromagnetic relief valve may be provided to relieve excess pressure in the bottom-side oil chamber and rod-side oil chamber of each of the boom cylinder 7, arm cylinder 8, and bucket cylinder 9 to the hydraulic oil tank.

[0050] The control system of the shovel 100 according to this embodiment includes a controller 30, an ECU 74, a discharge pressure sensor 14b, an operating pressure sensor 15a, a display device 40, an input device 42, a spatial recognition device 80, a state detection device S1, and a communication device T1.

[0051] The controller 30 controls the driving of the shovel 100. The functions of the controller 30 may be realized by any hardware, software, or a combination thereof. For example, the controller 30 is configured mainly with a computer including a processor such as a CPU (Central Processing Unit), a memory device such as a RAM (Random Access Memory), a non-volatile auxiliary storage device such as a ROM (Read Only Memory), and various input / output interface devices.

[0052] The controller 30 realizes various functions by, for example, executing various programs installed in an auxiliary storage device on a CPU.

[0053] For example, the controller 30 sets a target rotation speed based on a work mode or the like that is set in advance by a predetermined operation by an operator or the like, and outputs a control command to the ECU 74, thereby performing drive control via the ECU 74 to keep the engine 11 rotating at a constant speed.

[0054] Furthermore, for example, the controller 30 outputs a control command to the regulator 14a as necessary to change the discharge amount of the main pump 14, thereby performing so-called total horsepower control or negative control.

[0055] Furthermore, for example, the controller 30 may have a function (hereinafter referred to as "upload function") of uploading various information related to the shovel 100 to the management device 300. Specifically, the controller 30 may transmit (upload) work pattern record information and environmental condition record information during a predetermined type of work by the shovel 100 to the management device 300 via the communication device T1. The controller 30 includes, for example, an information transmission unit 301 as a functional unit related to the upload function, which is realized by executing, on a CPU, one or more programs installed in an auxiliary storage device or the like.

[0056] Furthermore, for example, the controller 30 performs control related to a machine guidance function that guides (provides guidance for) the manual operation of the shovel 100 by the operator via the operation device 26. Furthermore, the controller 30 may perform control related to a machine control function that automatically assists the manual operation of the shovel 100 by the operator via the operation device 26.

[0057] The controller 30 includes, for example, an operation information acquisition unit 302 and a machine guidance unit 303 as functional units related to machine guidance functions and machine control functions, which are realized by executing one or more programs installed on an auxiliary storage device or the like on a CPU.

[0058] Note that some of the functions of the controller 30 may be realized by another controller (control device). That is, the functions of the controller 30 may be realized in a distributed manner by a plurality of controllers. For example, the machine guidance function and the machine control function described above may be realized by a dedicated controller (control device).

[0059] The ECU 74 controls various actuators (for example, a fuel injection device) of the engine 11 in response to a control command from the controller 30, and causes the engine 11 to rotate at a set target rotation speed (set rotation speed) (constant rotation control). At this time, the ECU 74 performs constant rotation control of the engine 11 based on the rotation speed of the engine 11 detected by the engine rotation speed sensor 11a.

[0060] The discharge pressure sensor 14b detects the discharge pressure of the main pump 14. A detection signal corresponding to the discharge pressure detected by the discharge pressure sensor 14b is input to the controller 30.

[0061] As described above, the operating pressure sensor 15a detects the secondary pilot pressure of the operating device 26, that is, the pilot pressure corresponding to the operating state of each operating element (hydraulic actuator) in the operating device 26. A detection signal of the pilot pressure detected by the operating pressure sensor 15a, which corresponds to the operating state of the lower traveling structure 1, the upper rotating structure 3, the boom 4, the arm 5, the bucket 6, etc. in the operating device 26, is input to the controller 30.

[0062] The display device 40 is connected to the controller 30, and is provided at a position that is easily visible to an operator seated in the cabin 10, and displays various information images under the control of the controller 30. The display device 40 is, for example, a liquid crystal display or an organic EL (Electroluminescence) display.

[0063] The input device 42 is provided within reach of an operator seated in the cabin 10, accepts various operations by the operator, and outputs signals corresponding to the operations. For example, the input device 42 is integrated with the display device 40. Alternatively, the input device 42 may be provided separately from the display device 40. The input device 42 includes a touch panel mounted on the display of the display device 40, a knob switch provided at the tip of a lever included in the operation device 26, a button switch, lever, toggle, etc. provided around the display device 40. A signal corresponding to the operation performed on the input device 42 is input into the controller 30.

[0064] The display unit of a support device such as a mobile terminal may be used as the display device 40. The support device is typically a mobile terminal device, such as a notebook PC, tablet PC, or smartphone carried by a worker at a construction site. The support device may also be the support device 400 in this embodiment. The support device may also be a computer carried by the operator of the shovel 100. The support device may also be a fixed terminal device.

[0065] The spatial recognition device 80 captures images of the periphery of the shovel 100. The spatial recognition device 80 includes a camera 80F that captures images in front of the shovel 100, a camera 80L that captures images to the left of the shovel 100, a camera 80R that captures images to the right of the shovel 100, and a camera 80B that captures images behind the shovel 100.

[0066] Camera 80F is attached, for example, to the ceiling of cabin 10, i.e., inside cabin 10. Camera 80F may also be attached to the exterior of cabin 10, such as the roof of cabin 10 or the side of boom 4. Camera 80L is attached to the left end of the upper surface of the upper rotating body 3, camera 80R is attached to the right end of the upper surface of the upper rotating body 3, and camera 80B is attached to the rear end of the upper surface of the upper rotating body 3.

[0067] The spatial recognition device 80 (cameras 80F, 80B, 80L, 80R) is, for example, a monocular wide-angle camera having a very wide angle of view. The spatial recognition device 80 may also be a stereo camera, a distance imaging camera, or the like. Image data of the surroundings of the shovel 100 captured by the spatial recognition device 80 is input into the controller 30.

[0068] The spatial recognition device 80 is configured to acquire information about the three-dimensional space around the shovel 100. The spatial recognition device 80 may also be configured to calculate the distance from the spatial recognition device 80 or the shovel 100 to an object recognized by the spatial recognition device 80.

[0069] The spatial recognition device 80 is, for example, an ultrasonic sensor, a millimeter-wave radar, a monocular camera, a stereo camera, a LIDAR, a distance image sensor, or an infrared sensor. In this embodiment, the spatial recognition device 80 includes a front camera 80F attached to the front end of the upper surface of the cabin 10, a rear camera 80B attached to the rear end of the upper surface of the upper rotating body 3, a left camera 80L attached to the left end of the upper surface of the upper rotating body 3, and a right camera 80R attached to the right end of the upper surface of the upper rotating body 3. The front camera 80F may be omitted.

[0070] The spatial recognition device 80 is, for example, a monocular camera having an imaging element such as a CCD or CMOS, and outputs the captured image to the display device 40. In addition to using the captured image, when a LIDAR, millimeter wave radar, ultrasonic sensor, laser radar, or the like is used as the spatial recognition device 80, the spatial recognition device 80 may transmit a number of signals (laser light, etc.) toward an object and receive the reflected signals, thereby detecting the distance and direction of the object from the reflected signals.

[0071] The spatial recognition device 80 may be configured to detect objects present around the shovel 100. Examples of objects include terrain features (slope, holes, etc.), power lines, utility poles, people, animals, vehicles, construction machinery, buildings, walls, helmets, safety vests, work clothes, or predetermined marks on helmets. The spatial recognition device 80 may be configured to identify at least one of the type, position, and shape of an object. The spatial recognition device 80 may be configured to distinguish between people and non-human objects.

[0072] Furthermore, the spatial recognition device 80 may be a fixed-point installation type spatial recognition device 80 set at a fixed point on the work site, or a spatial recognition device 80 installed on a multicopter or the like may be used.

[0073] The spatial recognition device 80 is installed so that it can acquire information above the horizon in order to acquire weather information. Furthermore, the spatial recognition device 80 stores information indicating the position and orientation of the data acquired by the spatial recognition device 80 in association with the data so that the orientation of the captured image can be determined.

[0074] The state detection device S1 outputs detection information relating to various states of the shovel 100. The detection information output from the state detection device S1 is taken into the controller 30. The detection information may be included in operation information of the shovel 100.

[0075] For example, the state detection device S1 detects the attitude state and operating state of the attachment. Specifically, the state detection device S1 may detect the elevation and depression angles of the boom 4, arm 5, and bucket 6 (hereinafter referred to as the "boom angle," "arm angle," and "bucket angle," respectively). In other words, the state detection device S1 may include a boom angle sensor, an arm angle sensor, and a bucket angle sensor that detect the boom angle, arm angle, and bucket angle, respectively.

[0076] Furthermore, the state detection device S1 may detect the acceleration, angular acceleration, etc. of the boom 4, the arm 5, and the bucket 6. In this case, the state detection device S1 may include, for example, a rotary encoder, an acceleration sensor, an angular acceleration sensor, a six-axis sensor, an IMU (Inertial Measurement Unit), etc., which are attached to each of the boom 4, the arm 5, and the bucket 6. Furthermore, the state detection device S1 may include cylinder sensors which detect the cylinder position, speed, acceleration, etc. of the boom cylinder 7, the arm cylinder 8, and the bucket cylinder 9 which drive the boom 4, the arm 5, and the bucket 6, respectively.

[0077] Furthermore, for example, the state detection device S1 detects the attitude state of the machine body, that is, the lower running body 1 and the upper rotating body 3. Specifically, the state detection device S1 may detect the tilt state of the machine body with respect to the horizontal plane. In this case, the state detection device S1 may include, for example, an inclination sensor attached to the upper rotating body 3 that detects the tilt angles of the upper rotating body 3 around two axes in the fore-aft and lateral directions (hereinafter referred to as "fore-aft inclination angle" and "lateral inclination angle").

[0078] Furthermore, for example, the state detection device S1 detects the rotation state of the upper rotating body 3. Specifically, the state detection device S1 detects the rotation angular velocity and rotation angle of the upper rotating body 3. In this case, the state detection device S1 may include, for example, a gyro sensor, a resolver, a rotary encoder, etc. attached to the upper rotating body 3. In other words, the state detection device S1 may include a rotation angle sensor that detects the rotation angle, etc. of the upper rotating body 3.

[0079] Furthermore, for example, the state detection device S1 detects the state of action of a force acting on the excavator 100 through an attachment. Specifically, the state detection device S1 may detect the operating pressure (cylinder pressure) of a hydraulic actuator. In this case, the state detection device S1 may include pressure sensors that detect the pressures in the rod-side oil chamber and bottom-side oil chamber of each of the boom cylinder 7, arm cylinder 8, and bucket cylinder 9.

[0080] Furthermore, for example, the state detection device S1 may include a sensor that detects the displacement of a spool of a control valve in the control valve 17. Specifically, the state detection device S1 may include a boom spool displacement sensor that detects the displacement of a boom spool. Furthermore, the state detection device S1 may include an arm spool displacement sensor that detects the displacement of an arm spool.

[0081] The state detection device S1 may also include a bucket spool displacement sensor that detects the displacement of the bucket spool. The state detection device S1 may also include a swing spool displacement sensor that detects the displacement of the swing spool. The state detection device S1 may also include a right travel spool displacement sensor and a left travel spool displacement sensor that detect the displacement of the right travel spool and the left travel spool that constitute the right travel control valve and the left travel control valve, respectively.

[0082] Furthermore, for example, the state detection device S1 detects the position of the shovel 100 and the orientation of the upper rotating body 3. In this case, the state detection device S1 may include, for example, a GNSS (Global Navigation Satellite System) compass, a GNSS sensor, a direction sensor, etc. attached to the upper rotating body 3.

[0083] The communication device T1 communicates with external devices via the communication network NW. The communication device T1 is, for example, a mobile communication module compatible with mobile communication standards such as LTE (Long Term Evolution), 4G (4th Generation), and 5G (5th Generation), or a satellite communication module for connecting to a satellite communication network.

[0084] The information transmitting unit 301 transmits operation information of the shovel 100 to the management device 300 via the communication device T1. The operation information transmitted by the information transmitting unit 301 includes, for example, various types of detection information input from the state detection device S1.

[0085] Furthermore, the operation information transmitted by the information transmission unit 301 includes, for example, an image of the surroundings of the shovel 100 input from the spatial recognition device 80. Furthermore, the operation information transmitted by the information transmission unit 301 may include information on the internal environmental conditions of the shovel 100, for example, information on variable specifications such as a large-capacity bucket specification, a long arm specification, a quick coupling specification, etc.

[0086] For example, the information transmission unit 301 sequentially determines whether or not a predetermined target type of work is being performed, and when it determines that the target type of work is being performed, it links the work pattern performance information (i.e., various detection information input from the status detection device S1) and environmental condition information (i.e., images of the surroundings of the shovel 100 input from the spatial recognition device 80) for the period in which the work is being performed, and records them in an internal memory or the like.

[0087] At this time, date and time information regarding the start and end of the target type of work, as well as the location information of the shovel 100 during the work, may also be stored in the internal memory in a manner that further links them to the set of work pattern actual information and environmental condition actual information.

[0088] That is, the operation information in this embodiment includes image data of the periphery of the shovel 100 captured by the spatial recognition device 80 and location information indicating the position of the shovel 100. In other words, the image data of the periphery of the shovel 100 and the location information indicating the position of the shovel 100 are part of the operation information that the management device 300 receives from the shovel 100.

[0089] At this time, the date and time information may be acquired, for example, from a predetermined timekeeping means (for example, an RTC (Real Time Clock)) inside the controller 30. Then, the information transmitting unit 301 transmits the operation information to the management device 300 through the communication device T1 at a predetermined timing, such as when the key of the shovel 100 is turned off (when the shovel 100 is stopped). Furthermore, the information transmitting unit 301 may transmit the operation information to the management device 300 through the communication device T1 every time a task of the target type is performed, after the task is completed.

[0090] The environmental condition record information may include detection information detected by other sensors mounted on the shovel 100 instead of or in addition to the spatial recognition device 80. For example, the shovel 100 may be equipped with other sensors such as millimeter wave radar, LIDAR (Light Detecting and Ranging), etc., and the environmental condition record information may include detection information from these distance sensors.

[0091] The same applies to the current environmental condition information described below. Furthermore, the environmental condition record information may include meteorological information. The meteorological information may include, for example, information detected by a raindrop sensor, an illuminance sensor, or the like, which are examples of the state detection device S1.

[0092] The current environmental condition performance information may also include information about the internal environmental conditions of the shovel 100, such as variable specifications such as a large-capacity bucket specification, a long arm specification, or a quick coupling specification.

[0093] The machine guidance unit 303 controls the machine guidance function and the machine control function. That is, the machine guidance unit 303 supports the operation of various operating elements (the lower traveling body 1, the upper rotating body 3, and attachments including the boom 4, the arm 5, and the bucket 6) by the operator through the operation device 26.

[0094] For example, when the operator is operating the arm 5 via the operation device 26, the machine guidance unit 303 may automatically operate at least one of the boom 4 and the bucket 6 so that a target design plane (hereinafter simply referred to as the "design plane") that is defined in advance as a target trajectory coincides with the tip of the bucket 6 (for example, the tip or back surface as a working part). Furthermore, the machine guidance unit 303 may also automatically operate the arm 5 regardless of the operating state of the operation device 26 that operates the arm 5. In other words, the machine guidance unit 303 may cause the attachment to perform a predetermined operation when triggered by operation of the operation device 26 by the operator.

[0095] More specifically, the machine guidance unit 303 acquires various types of information from the state detection device S1, the spatial recognition device 80, the communication device T1, the input device 42, etc. Furthermore, the machine guidance unit 303 calculates, for example, the distance between the bucket 6 and the design surface based on the acquired information. Then, the machine guidance unit 303 appropriately controls the operation valve 31 in accordance with the calculated distance between the bucket 6 and the design surface, etc., and can automatically operate each hydraulic actuator by individually and automatically adjusting the pilot pressure acting on the control valve corresponding to the hydraulic actuator.

[0096] The operating valves 31 include, for example, a boom proportional valve corresponding to the boom 4 (boom cylinder 7). The operating valves 31 also include, for example, an arm proportional valve corresponding to the arm 5 (arm cylinder 8). The operating valves 31 also include, for example, a bucket proportional valve corresponding to the bucket 6 (bucket cylinder 9).

[0097] The operation valves 31 also include, for example, a swing proportional valve corresponding to the upper swing body 3 (swing hydraulic motor 2A). The operation valves 31 also include, for example, a right traveling proportional valve and a left traveling proportional valve corresponding to the right crawler and the left crawler of the lower traveling body 1, respectively.

[0098] For example, in order to support excavation work, the machine guidance unit 303 may automatically extend and retract at least one of the boom cylinder 7, the arm cylinder 8, and the bucket cylinder 9 in response to an opening / closing operation of the arm 5 using the operating device 26. The excavation work is work in which the toe of the bucket 6 is used to excavate the ground along a design surface. For example, when the operator manually operates the operating device 26 to close the arm 5 (hereinafter referred to as the "arm closing operation"), the machine guidance unit 303 automatically extends and retracts at least one of the boom cylinder 7 and the bucket cylinder 9.

[0099] The machine guidance unit 303 may also automatically extend and retract at least one of the boom cylinder 7, arm cylinder 8, and bucket cylinder 9 to assist in finishing work on slopes or horizontal surfaces, for example. Finishing work includes, for example, pulling the bucket 6 toward you along the design surface while pressing the back of the bucket 6 against the ground.

[0100] For example, when an operator manually performs an arm closing operation using the operation device 26, the machine guidance unit 303 automatically extends and retracts at least one of the boom cylinder 7 and the bucket cylinder 9. This allows the bucket 6 to move along the design surface, which is the slope (embankment) or horizontal surface after completion, while pressing the back surface of the bucket 6 against the slope (embankment) or horizontal surface before completion with a predetermined pressing force.

[0101] The machine guidance unit 303 may also automatically rotate the swing hydraulic motor 2A to make the upper swing body 3 face the design surface. In this case, the machine guidance unit 303 may make the upper swing body 3 face the design surface by operating a predetermined switch included in the input device 42. The machine guidance unit 303 may also make the upper swing body 3 face the design surface and start the machine control function by simply operating a predetermined switch.

[0102] Furthermore, for example, when a predetermined type of work (e.g., excavation work, loading work, finishing work, etc.) is being performed, the machine guidance unit 303 controls the operation of at least a portion of the attachment, upper rotating body 3, and lower running body 1 in accordance with the operator's operation of the operating device 26 so as to match the work pattern (optimal work pattern) acquired by the operation information acquisition unit 302.

[0103] This allows the operator, regardless of his or her level of proficiency in operating the shovel 100, to adjust the operation of the shovel 100 to an optimal work pattern for the current environmental conditions of the shovel 100, which is output from the management device 300 so as to relatively increase a predetermined target indicator, for example, the evaluation of work speed.

[0104] Furthermore, the machine guidance unit 303 may control the operation of the shovel 100 based on the optimal work pattern, while causing the display device 40 to display the operation of the shovel 100 corresponding to the optimal work pattern for the operator. For example, when the machine guidance unit 303 controls the operation of the shovel 100 based on the optimal work pattern, it causes the display device 40 to display a video of the simulation results corresponding to the optimal work pattern. This allows the operator to proceed with work while checking the content of the actual work pattern on the video on the display device 40.

[0105] Next, a description will be given of the management device 300 of this embodiment. The management device 300 of this embodiment includes a storage unit 320 and a notification determination unit 330.

[0106] The storage unit 320 stores various types of information that are referenced when the notification determination unit 330 executes processing. The information stored in the storage unit 320 will be described in detail later.

[0107] The notification determination unit 330 identifies an excavator 100 that is parked within a predetermined range and requires maintenance, based on the operation information received from the excavator 100, and notifies a service person. Details of the notification determination unit 330 will be described later.

[0108] The following describes the management device 300 of this embodiment. Fig. 3 is a diagram showing an example of the hardware configuration of the management device.

[0109] The management device 300 of this embodiment is a computer including an input device 311, an output device 312, a drive device 313, an auxiliary storage device 314, a memory device 315, an arithmetic processing device 316, and an interface device 317, which are all interconnected by a bus B.

[0110] The input device 311 is a device for inputting various types of information and is realized by, for example, a keyboard, a pointing device, etc. The output device 312 is for outputting various types of information and is realized by, for example, a display, etc. The interface device 317 includes a LAN card, etc., and is used for connecting to a network.

[0111] The management program that realizes the notification determination unit 330 is at least a part of various programs that control the management device 300. The support program is provided, for example, by distributing a storage medium 318 or by downloading it from a network. The storage medium 318 that records the management program can be of various types, including storage media that record information optically, electrically, or magnetically, such as a CD-ROM, a flexible disk, or a magneto-optical disk, and semiconductor memory that records information electrically, such as a ROM or flash memory.

[0112] When a storage medium 318 storing these programs is set in a drive device 313, the assistance programs are installed from the storage medium 318 into the auxiliary storage device 314 via the drive device 313. The programs downloaded from the network are installed into the auxiliary storage device 314 via an interface device 317.

[0113] The auxiliary storage device 314 realizes each storage unit etc. of the management device 300, and stores the assistance program installed in the management device 300 as well as various files, data etc. required by the management device 300. The memory device 315 reads and stores the assistance program from the auxiliary storage device 314 when the management device 300 is started. The arithmetic processing device 316 then realizes various processes as described below in accordance with the assistance program stored in the memory device 315.

[0114] Next, the functions of the management device 300 of this embodiment will be described with reference to Fig. 4. Fig. 4 is a diagram illustrating the functions of the management device of this embodiment.

[0115] The management device 300 of this embodiment has a storage unit 320 and a notification determination unit 330. The storage unit 320 is realized, for example, by the auxiliary storage device 314 of the management device 300. The notification determination unit 330 is realized by the arithmetic processing unit 316 of the management device 300 reading and executing an assistance program stored in the memory device 315.

[0116] First, a description will be given of the storage unit 320. The storage unit 320 stores operation information of construction machines including the shovel 100, information on service personnel who perform maintenance on the construction machines, information on the maintenance schedule for the construction machines, and the like.

[0117] Specifically, the storage unit 320 stores construction machine management information 321, serviceman management information 322, and schedule management information 323.

[0118] In this embodiment, a part of the construction machine management information 321 and the serviceman management information 322 may be transmitted from the branch terminal 500 to the management device 300 and stored in advance, for example.

[0119] Furthermore, in this embodiment, when the scheduled date and time of maintenance is input from the support device 400 of the service technician, the schedule management information 323 including the input scheduled date and time may be stored in the storage unit 320.

[0120] The construction machinery management information 321 includes information items such as store code, machine number, and operation information, which are all associated with each other. The value of the "store code" item is, for example, identification information that identifies the branch office of the rental company that rents out the construction machinery. In other words, the value of the "store code" item is manager identification information that identifies the manager of the construction machinery.

[0121] The value of the item "machine number" is identification information for identifying the construction machine. The value of the item "operation information" is operation information received from the construction machine.

[0122] In the construction machinery management information 321 of this embodiment, the values ​​of the item "store code" and the item "machine number" may be registered in advance in the storage unit 320 by the branch office terminal 500.

[0123] Then, when the management device 300 receives operation information from a construction machine, the management device 300 may associate the operation information with a store code corresponding to the machine number included in the received operation information.

[0124] The serviceman management information 322 includes information items such as a store code, a serviceman ID, and a terminal ID, which are associated with each other. The value of the item "serviceman ID" is identification information that identifies a serviceman who belongs to the branch indicated by the store code. The value of the item "terminal ID" is terminal identification information that identifies the support device 400 owned by the serviceman. Specifically, the value of the item "terminal ID" may be the phone number of the smartphone (support device 400) owned by the serviceman.

[0125] The schedule management information 323 includes information items such as a shop code and schedule information, which are associated with each other. The value of the "schedule information" item indicates the scheduled date and time of construction machine maintenance. Specifically, since the scheduled date and time of maintenance is entered by a service technician, the value of the "schedule information" item includes the scheduled date and time of maintenance and the service technician ID of the service technician who entered the scheduled date and time of maintenance.

[0126] In this way, the memory unit 320 of this embodiment stores, in correspondence with each other, a machine number that identifies the construction machine, manager identification information that identifies the manager of the construction machine, and terminal identification information that identifies the service technician's support device 400.

[0127] Next, a description will be given of the notification determination unit 330. The notification determination unit 330 of this embodiment includes a communication control unit 331, an extraction unit 332, a state determination unit 333, a target identification unit 334, and a notification destination identification unit 335.

[0128] The communication control unit 331 controls communication between the management device 300 and external devices. Specifically, the communication control unit 331 controls transmission and reception of information with construction machines including the shovel 100, the support device 400, the branch terminal 500, etc.

[0129] Specifically, the communication control unit 331 receives operation information from the construction machine. The communication control unit 331 also transmits a notification regarding the construction machine requiring maintenance to the service technician support device 400. The communication control unit 331 also receives schedule management information including the scheduled date and time of maintenance from the service technician support device 400.

[0130] That is, the communication control unit 331 of this embodiment is an example of an output unit that outputs various types of information from the management device 300. Also, the communication control unit 331 of this embodiment is an example of an input receiving unit that receives input of various types of information.

[0131] The extraction unit 332 extracts operation information of construction machines whose operation information has been received and whose positions indicated by the position information included in the operation information are within a predetermined range.

[0132] The status determination unit 333 determines the status of each construction machine from the extracted operation information. Specifically, the status determination unit 333 determines whether the status of the construction machine is such that maintenance is required. Maintenance in this embodiment refers to work performed by a service technician, and includes, for example, periodic maintenance, repair of abnormalities or malfunctions, etc.

[0133] The status determination unit 333 determines whether maintenance is required based on the operating time. Specifically, for example, the status determination unit 333 outputs a maintenance notice when the time until the next maintenance falls within a predetermined time. Furthermore, the status determination unit 333 outputs a maintenance warning if the maintenance has not been performed even after the time for the next maintenance has passed. The time until the next maintenance may be determined based not only on the operating time but also on the work content (for example, work pattern performance information), workload, etc.

[0134] Furthermore, the state determination unit 333 may determine the time until the next maintenance based on environmental condition record information, etc. The state determination unit 333 also determines whether or not an abnormality (failure) has occurred based on thresholds set for detection information from various sensors, etc. In this case, the state determination unit 333 may set multiple thresholds and determine the degree of the abnormality in multiple stages (for example, mild abnormality, severe abnormality, etc.).

[0135] The target identification unit 334 identifies the construction machine that is the target of work by the service technician, according to the determination result by the status determination unit 333. Specifically, the target identification unit 334 identifies the construction machine that has been determined by the status determination unit 333 to require maintenance as the construction machine to be maintained.

[0136] In other words, the extraction unit 332, the state determination unit 333, and the target identification unit 334 of this embodiment are an example of an identification unit that identifies a construction machine whose state is to be notified to the support device 400.

[0137] The notification destination specification unit 335 specifies the destination of a notification regarding the construction machine that is the maintenance target. Specifically, the notification destination specification unit 335 specifies the shop code that corresponds to the model number of the construction machine that is the maintenance target, and specifies the support device 400 of the service technician that is associated with the specified shop code as the notification destination.

[0138] In other words, the notification destination identification unit 335 of this embodiment refers to a memory unit in which the machine number identifying the construction machine, the administrator identification information identifying the administrator who manages the construction machine, and the terminal identification information identifying the support device are stored in association with each other, and identifies the support device associated with the construction machine to be maintained as the notification output destination.

[0139] Next, the operation of the support system SYS will be described with reference to Fig. 5. Fig. 5 is a sequence diagram illustrating the operation of the support system.

[0140] In the support system SYS, the shovel 100 acquires its own operation information through the operation information acquisition unit 302 (step S501). Subsequently, the shovel 100 transmits the operation information to the management device 300 through the information transmission unit 301 (step S502).

[0141] In this embodiment, a construction machine including the shovel 100 may transmit operation information to the management device 300, for example, after work for the day is completed. Also, in this embodiment, a construction machine including the shovel 100 may transmit operation information including location information to the management device 300, for example, after work is completed and the construction machine is transported by trailer or the like from a work site to a parking area, and when the engine 11 is turned on to descend from the trailer to the parking area, the construction machine may transmit operation information including location information to the management device 300. Also, at this time, only the location information may be transmitted to the management device 300 separately from the operation information of the shovel 100.

[0142] When the management device 300 receives the operation information, the notification determination unit 330 performs a notification determination process (step S503). The process of step S503 will be described in detail later.

[0143] When the notification destination is identified by the notification determination unit 330, the management device 300 transmits a notification to the support device 400 of the notification destination, indicating that the construction machine to be maintained is waiting at the parking area (step S504).

[0144] When the support device 400 receives this notification, it displays the notification on the display screen of the support device 400 (step S505).

[0145] Next, when the support device 400 receives an instruction to display a list of construction machines to be maintained, it requests list information from the management device 300 (step S506). The management device 300 receives the request for list information and transmits the list information to the support device 400 (step S507). At this time, the management device 300 may transmit the list information of the maintenance targets, information on the maintenance content, etc. to the support device 400 at the same time as transmitting the list information.

[0146] The support device 400 displays the list information received from the management device 300 and accepts the selection of a machine number from the list of construction machines to be maintained (step S508). Next, the support device 400 displays information regarding the maintenance content of the selected construction machine and accepts input of the scheduled date and time of maintenance (step S509).

[0147] The information regarding the maintenance content may be acquired by the support device 400 together with the list information. Furthermore, the support device 400 may acquire information regarding the maintenance content of the selected construction machine from the management device 300 every time the support device 400 receives a selection of a construction machine from the list information.

[0148] When the support device 400 receives input of the scheduled date and time of maintenance (schedule information), it transmits schedule management information 323, which associates the serviceman ID of the serviceman who owns the support device 400 with the schedule information, to the management device 300 (step S510).

[0149] In addition, the management device 300 accepts an inquiry from the branch terminal 500 regarding the status of the construction machinery managed by the branch where the branch terminal 500 is installed (step S511), and transmits information indicating the status of the construction machinery, including schedule information, to the branch terminal 500 (step S512).

[0150] When the branch office terminal 500 receives the information indicating the status from the management device 300, it displays the received information (step S513).

[0151] In this embodiment, in response to an inquiry from the branch terminal 500, information indicating the status of the construction machines waiting in the parking area and maintenance schedule information for the construction machines are displayed on the branch terminal 500.

[0152] In this way, in this embodiment, the service technician and the branch office can share schedules such as planned maintenance dates.

[0153] Next, the notification determination process by the notification determination unit 330 will be described with reference to Fig. 6. Fig. 6 is a flowchart illustrating the process of the management device. The process shown in Fig. 6 is a detailed description of the process of step S503 in Fig. 5.

[0154] The management device 300 of this embodiment uses the communication control unit 331 of the notification determination unit 330 to refer to operation information received from construction machines including the shovel 100 (step S601). Next, the notification determination unit 330 uses the extraction unit 332 to extract operation information of construction machines waiting within a predetermined range from the construction machines for which operation information has been received (step S602).

[0155] Specifically, the extraction unit 332 extracts operation information of construction machines whose current positions, indicated by the position information included in the operation information, are within a predetermined range. In this embodiment, construction machines whose current positions are within a predetermined range are considered to be construction machines waiting in the parking lot of a branch office.

[0156] Next, the notification determination unit 330 determines whether or not there are any construction machines that require maintenance based on each piece of extracted operation information using the status determination unit 333 (step S603). If there are no construction machines that require maintenance in step S603, the notification determination unit 330 ends the process.

[0157] In step S603, if there is a construction machine that requires maintenance, the notification determination unit 330 causes the target identification unit 334 to identify the construction machine that requires maintenance and the details of the maintenance (step S604). Specifically, the target identification unit 334 identifies the model number of the construction machine that has been determined to require maintenance by the status determination unit 333. In other words, the target identification unit 334 identifies the construction machine that is the target of maintenance.

[0158] Next, the notification determination unit 330 causes the notification destination specification unit 335 to specify the destination of the notification indicating that the construction machine to be maintained is waiting in the parking area (step S605), and proceeds to step S504 in FIG.

[0159] Specifically, the notification destination specification unit 335 refers to the construction machinery management information 321 and specifies the manager identification information associated with the model number of the construction machinery to be maintained. Then, the notification destination specification unit 335 refers to the serviceman management information 322 and specifies the support device 400 specified by the terminal ID associated with the manager identification information as the support device 400 to be notified.

[0160] In this embodiment, construction machines waiting within a predetermined range are identified based on the position information of the construction machines, and the status of the identified construction machines is determined. Then, in this embodiment, only when a construction machine waiting within the predetermined range requires maintenance is the support device 400 for the service technician notified of this.

[0161] Therefore, according to this embodiment, it is possible to notify the service technician of information about construction machines waiting at the parking lot, which allows the service technician to know when to perform maintenance, and prevents the occurrence of a situation where the service technician heads to the parking lot only to find that the construction machine to be maintained is not waiting there.

[0162] Next, a display example of the support device 400 in this embodiment will be described. The support device 400 in this embodiment may display each screen described later on a display using, for example, a browser function. Furthermore, the support device 400 in this embodiment may have an application installed thereon that communicates with the management device 300 and displays the screen described later.

[0163] Fig. 7 is a first diagram showing a display example of the support device. A screen 71 is displayed on the support device 400 shown in Fig. 7. The screen 71 shown in Fig. 7 is an example of a screen displayed on the support device 400 in, for example, step S505 of Fig. 5.

[0164] In the screen 71, the home screen of the support device 400 is displayed in the background, and a push notification 72 is displayed on the home screen.

[0165] The push notification 72 displays a message indicating that an excavator 100 requiring maintenance is waiting in the parking lot of the branch office to which the service technician who owns the support device 400 belongs.

[0166] When the support device 400 receives an operation to select this push notification 72, it transmits to the management device 300 a request to acquire list information of construction machines that are the target of maintenance.

[0167] Upon receiving this request, the management device 300 causes the support device 400 to display a list of information on the construction machines that are the maintenance targets.

[0168] Fig. 8 is a second diagram showing an example of a display on the support device. Fig. 8 shows an example of a screen 81 displayed on the support device 400. The screen 81 is an example of a screen displaying a list of construction machines that are the target of maintenance. The screen 81 is an example of a screen displayed on the support device 400, for example, in step S508 of Fig. 5.

[0169] In Fig. 8, a list of construction machines that are the subject of maintenance is displayed in the display area 82. In this embodiment, the list of construction machines that is displayed in the display area 82 includes the machine number of the construction machine identified in step S604 in Fig. 6 and the determination result of the status determination unit 333 based on the operation information corresponding to this machine number. In other words, the list of construction machines may include the machine number of the construction machine that is the subject of maintenance and information indicating the status of the construction machine that is the subject of maintenance. In this embodiment, the status of the construction machine may also be represented by an icon image or the like.

[0170] The list information may also include the date and time when the management device 300 acquired the operating status used in the status determination by the status determination unit 333, and information indicating the lender of the construction machine.

[0171] 8, the model number "SM05" is displayed in association with the icon image 82a. The icon image 82a includes two images, one large and one small. In the icon image 82a, the small image indicates, for example, that "regular maintenance is required (the time has passed)," and the large image indicates, for example, that "a low-importance abnormality has occurred."
