[0004] In recent years, in order to improve construction efficiency, the introduction of construction machines capable of automatic (autonomous) operation as described in Patent Document 1 has been promoted. Although it is desirable to complete all construction work by work performed by automatically operated construction machines, for example, in precise work and finishing processes, work by construction machines manually operated by an operator may be required in some cases. That is, within a work area, automatically operated construction machines and manually operated construction machines coexist.

[Modes for carrying out the invention]

[0015] Hereinafter, with reference to the drawings, a work management system and a work management method according to an embodiment of the present invention will be described.

[0016] First, with reference to Figures 1 to 3, a work management system 100 according to an embodiment of the present invention will be described.

[0017] As shown in Figure 1, the work management system 100 is a system constructed to centrally manage the work of multiple construction machines 2, which are capable of both automated and manual operation, deployed at multiple work sites 1A, 1B, and 1C. The multiple work sites 1A, 1B, and 1C managed by the work management system 100 are, for example, civil engineering work areas set up in locations several hundred kilometers or more apart from each other. Note that the multiple work sites 1A, 1B, and 1C may be multiple work areas set up within a single civil engineering construction site.

[0018] Furthermore, work sites 1A, 1B, and 1C are not limited to domestic civil engineering work sites; they may also be overseas civil engineering work sites, or even extraterrestrial civil engineering work sites such as the lunar surface. Additionally, the number of work sites 1A, 1B, and 1C under management can be any number, as long as there are two or more locations.

[0019] The work management system 100 comprises a site management unit 30 installed at each work site 1A, 1B, and 1C (work area), and a work management unit 10 that manages the work status of multiple construction machines 2 deployed at each work site 1A, 1B, and 1C via the site management unit 30. The work management unit 10 and each site management unit 30 are connected to each other via a communication network 50 such as a public telephone line. In the following description, we will explain the case in which the work management system 100 manages the work of construction machines 2 that are involved in civil engineering work to construct embankment bodies such as trapezoidal dams by piling up embankment materials such as CSG (Cemented Sand and Gravel).

[0020] The work management unit 10 mainly consists of a microcomputer equipped with a CPU (Central Processing Unit) as a control unit 11, ROM (Read Only Memory) and RAM (Random Access Memory) as storage units 15, and an input / output interface (I / O interface); a communication unit 12 that exchanges data with each site management unit 30 via a communication network 50; a display unit 13 that can display the results calculated by the control unit 11 and the work status of each work site 1A, 1B, and 1C in real time; and an input unit 14 that accepts input operations from operators managing the work. The storage unit 15 pre-stores programs executed by the control unit 11 and data necessary for program execution, as well as sequentially stores the results calculated by the control unit 11. The specific control performed by the control unit 11 will be described later.

[0021] The work management unit 10 is installed in a location separate from each work site 1A, 1B, and 1C in order to centrally manage the operations of multiple construction machines 2 deployed at each work site 1A, 1B, and 1C. However, the work management unit 10 may also be installed at any of the work sites 1A, 1B, and 1C.

[0022] Next, with reference to Figure 2, we will describe the site management units 30 installed at each work site 1A, 1B, and 1C, and the construction machinery 2 deployed at each work site 1A, 1B, and 1C. Figure 2 shows a schematic configuration of one of the multiple work sites 1A, 1B, and 1C, specifically work site 1A.

[0023] The site management unit 30, like the work management unit 10, mainly consists of a microcomputer equipped with a CPU (Central Processing Unit) as a control unit 31, ROM (Read Only Memory) and RAM (Random Access Memory) as storage units 35, and an input / output interface (I / O interface); a communication unit 32 that exchanges data with the work management unit 10 via a communication network 50; a display unit 33 that can display the results calculated by the control unit 11 of the work management unit 10, the situation within the work site 1A, and the status of each construction machine 2 in real time; and an input unit 34 that accepts input operations from operators managing the work.

[0024] Furthermore, the site management unit 30 includes a transmitting / receiving unit 36 ​​that exchanges data with each construction machine 2, and an imaging unit 37 that captures images of the work site 1A. The transmitting / receiving unit 36 ​​is a wireless communication means such as LTE (Long Term Evolution), 5G, or Wi-Fi (registered trademark), and the imaging unit 37 is a camera installed at multiple locations within the work site 1A. The site management units 30 installed at the other work sites 1B and 1C have a similar configuration.

[0025] The construction machine 2 deployed at the work site 1A is configured to operate automatically (autonomously) by mounting the following components on a general-purpose construction machine: a position acquisition unit 42 capable of receiving signals from GPS satellites and other components of the Global Navigation Satellite System (GNSS); a state detection unit 43 capable of detecting acceleration, angular velocity, and geomagnetic field; an environment detection unit 44 capable of detecting surrounding obstacles; a transmission / reception unit 45 that exchanges data with the site management unit 30; and a control unit 41 that controls the operation of the construction machine 2 based on the information acquired by these units.

[0026] The position acquisition unit 42 is a positioning sensor capable of detecting the position (latitude, longitude, altitude) of the construction machine 2 based on signals from multiple positioning satellites. The state detection unit 43 is a so-called inertial measurement unit (IMU) that integrates an acceleration sensor, gyro sensor, barometric pressure sensor, and geomagnetic sensor capable of detecting the state of the construction machine 2. The state detection unit 43 also includes an engine operation detection sensor that detects the operating status of the construction machine 2, and a voltmeter and ammeter that detect the voltage and current of the construction machine 2's battery and electrical components. The surrounding detection unit 44 is a three-dimensional range sensor such as a laser scanner that can recognize the surrounding space by irradiating light and measuring the reflected light reflected by an object, a so-called 3D-LiDAR (light detection and ranging) sensor, and a radar sensor (RADAR: Radio Detection and Ranging) that can measure the distance to an object using radio waves. The transmitting and receiving unit 45 is a wireless communication means similar to the transmitting and receiving unit 36 ​​of the site management unit 30.

[0027] The control unit 41 is mainly composed of a CPU (Central Processing Unit) and is connected to an existing control unit 48 that is pre-installed on the construction machine 2. The control unit 41 detects the state and shape of the workpiece, such as embankment material, from the results detected by the surrounding detection unit 44 and confirms the safety of the surroundings, while confirming its own position and posture from the results detected by the position acquisition unit 42 and the state detection unit 43, thereby controlling the steering of the construction machine 2 to autonomously perform the instructed work. The automatic (autonomous) operation of the construction machine 2 may be performed by sequence control, which controls based on a predetermined order and judgment, or by feedback control, which controls based on the shape and quantity of the workpiece, such as embankment material, measured by the surrounding detection unit 44, or by a combination of these controls.

[0028] Here, the existing control unit 48 controls the steering and engine output of the construction machine 2 in response to the operation of existing operating parts 49, such as handles and levers, which are pre-installed on the construction machine 2 for manual steering, etc., by the operator. In other words, by generating a signal equivalent to the signal generated when the existing operating parts 49 are operated in the control unit 41 and transmitting the generated pseudo-signal to the existing control unit 48, it is possible to move the construction machine 2 as if it were being operated by an operator.

[0029] Furthermore, since the existing control unit 49 remains installed on construction machine 2, it is possible for an operator to manually operate construction machine 2 by boarding it.

[0030] Furthermore, the construction machine 2 is equipped with an imaging unit 46 capable of capturing images of the work site 1A visible from the driver's cab, and a sound collection device (not shown) that picks up sounds of the construction machine 2, etc., so that an operator can control the construction machine 2 from a distance. The imaging unit 46 is preferably, for example, a stereo camera capable of capturing images of the surrounding environment of the construction machine 2, and the imaging direction changes according to the orientation and movement of the operator's head when operating it with the remote control unit 20 described later.

[0031] Thus, the construction machine 2 is configured to be capable of automatic (autonomous) operation, as well as manual operation with an operator on board, and manual operation by an operator operating it remotely. In other words, the manual operation of the construction machine 2 described below includes cases where the operator is on board the construction machine 2 and operates it, and cases where the operator does not board the construction machine 2 but operates it remotely from the remote control unit 20 described later.

[0032] Construction machinery 2, configured to be capable of both automated and manual operation, includes, for example, bulldozers, dump trucks, vibratory rollers, and backhoes. The work performed by these different types of construction machinery 2 deployed at the work site 1A is managed by the site management unit 30 and also managed by the work management unit 10 via the site management unit 30. Although the configuration of the existing control unit 49 differs depending on the type of construction machinery 2, the configuration necessary to enable automated operation and remote control is almost the same.

[0033] The work management system 100 further includes a remote control unit 20 for remotely operating construction machinery 2 deployed at each work site 1A, 1B, and 1C from a location away from each work site 1A, 1B, and 1C.

[0034] As shown in Figure 1, the remote control unit 20 mainly consists of a microcomputer equipped with a CPU (Central Processing Unit) as a remote control unit 21, a plurality of remote control devices 24 connected to the remote control unit 21, and a display unit 22 capable of displaying the schedule for remote control and the work status of the construction machine 2 being remotely controlled in real time. The remote control unit 20 may be directly connected to the control unit 11 of the work management unit 10, or it may be connected to the work management unit 10 via a communication network 50. Furthermore, the remote control unit 20 may be installed in the same location as the work management unit 10, or it may be installed in a location away from the work management unit 10 or at any of the work sites 1A, 1B, 1C.

[0035] The remote control device 24 includes an operating unit 27 such as a handle or lever for operating the construction machine 2, a display unit 26 that displays images captured by an imaging unit 46 installed on the construction machine 2 and work details, and a speaker (not shown) for emitting sounds from the surroundings of the construction machine 2. The operation of these components is controlled by a control unit 25 mainly composed of a CPU (Central Processing Unit). The display unit 26 may be, for example, a head-mounted display worn by the operator.

[0036] Next, the control performed by the control unit 11 of the work management unit 10 in the work management system 100 configured in this way will be explained with reference to Figure 3.

[0037] As shown in Figure 3, the control unit 11 includes a work area setting unit 11A that sets up an automated work area where the construction machinery 2 performs work by automated operation and a manual work area where the construction machinery 2 performs work by manual operation within each work site 1A, 1B, and 1C based on 3D data such as CIM (Construction Information Modeling) data for each work site 1A, 1B, and 1C; a work planning unit 11B that plans the content of the work to be performed by each construction machinery 2 in each work area set up by the work area setting unit 11A based on the specifications of each construction machinery 2; and a schedule such as a Gantt chart that sets the order and time of the work to be performed by the work planning unit 11B. The system includes a schedule generation unit 11C that generates a schedule, a notification unit 11D that displays the schedule generated by the schedule generation unit 11C on the display unit 13, the display unit 33 of each site management unit 30, and the display unit 22 of the remote control unit 20, a determination unit 11E that determines the completion status of the work planned by the work planning unit 11B based on the location information of each construction machine 2 and signals transmitted from each construction machine 2, and an operation switching unit 11F that switches the operating state of each construction machine 2 to either an automatic operation state or a manual operation state, for example, in accordance with the determination by the determination unit 11E.

[0038] Three-dimensional data such as CIM data used in the work area setting unit 11A is stored in advance in the storage unit 15 and the storage units 35 of each site management unit 30. Alternatively, the data used in the work area setting unit 11A may be input by an operator via the input unit 14.

[0039] The specifications of each construction machine 2 used in the work planning unit 11B are entered in advance by the operator via the input unit 34 of the site management unit 30. For example, if the construction machine 2 is a bulldozer, the blade width, etc., is entered as the specifications; if it is a dump truck, the maximum load capacity and travel speed are entered; and if it is a vibratory roller, the roller width, etc., are entered.

[0040] Furthermore, when planning the work in the work planning unit 11B, construction machinery 2 that is undergoing inspection or repair at each work site 1A, 1B, and 1C is excluded from the plan, and only construction machinery 2 that is in a state where it can perform work is included in the plan. Whether or not a construction machine 2 is in a state where it can perform work is entered by the operator at any time via the input unit 34 of the site management unit 30. In addition, since each construction machine 2 originally has an abnormality detection function that detects abnormalities in actuators etc. that operate the work machine based on hydraulic oil pressure sensors and hydraulic oil temperature sensors (not shown), it is also possible to determine at any time whether or not a construction machine 2 is in a state where it can perform work based on the presence or absence of abnormalities transmitted from each construction machine 2.

[0041] The work details planned in the work planning unit 11B include, for example, the automated work details in which the construction machine 2 performs work by automated operation within the automated operation work area. Specifically, this includes the starting position where the automated work begins, the ending position where the automated work ends, and the route from the starting position to the ending position. This data is then transmitted to the construction machine 2 responsible for the work via the site management unit 30. The automated work details include, for example, the work performed on the work object such as embankment material, the work area in which the work is performed, and target values ​​(target shape, target specifications) within the work area. These are set according to the work performed by each construction machine 2, as described later. Once the work area and target values ​​within the work area are set, the construction machine 2 performs the work by automated operation within the work area in order to achieve the target values.

[0042] Furthermore, the work details planned in the work planning unit 11B include, for example, manual operation work in which the construction machine 2 performs work by manual operation within the manual operation work area. When an operator boards the construction machine 2, the work details planned in the work planning unit 11B are transmitted via the site management unit 30 to a terminal equipped on the construction machine 2 or to a tablet terminal held by the operator, and when the operator remotely operates the construction machine 2 using the remote control unit 20, they are transmitted to the remote control device 24.

[0043] As described later, the schedule generation unit 11C generates a schedule such that the times (times) when the construction machinery 2 is in manual operation mode do not overlap as much as possible between the work sites 1A, 1B, and 1C. This allows the operator remotely controlling the construction machinery 2 with the remote control unit 20 to sequentially operate the construction machinery 2 deployed at multiple work sites 1A, 1B, and 1C, and as a result, the number of operators required can be reduced.

[0044] The results determined by the determination unit 11E are displayed via the notification unit 11D on the display unit 13, the display units 33 of each site management unit 30, and the display unit 22 of the remote control unit 20, similar to the schedule generated by the schedule generation unit 11C. This makes it easy to grasp the progress of the work.

[0045] Furthermore, the operating status of each construction machine 2, whether it is in automatic or manual operation mode, is also displayed via the notification unit 11D on the display unit 13, the display unit 33 of each site management unit 30, and the display unit 22 of the remote control unit 20. This allows, for example, an operator to determine which construction machine 2 is in a state where it can be operated manually, i.e., remotely controlled, by looking at the display unit 22 of the remote control unit 20.

[0046] It should be noted that these work area setting units 11A, etc., represent the functions of the control unit 11 as virtual units and do not imply their physical existence. Furthermore, the above functions are only a part of the control performed by the control unit 11, and the control unit 11 also performs control related to other functions as needed.

[0047] Next, referring to Figures 4-7, we will specifically explain the work management method for the construction machinery 2 performed by the work management system 100 with the above configuration. In the following, we will explain using a civil engineering work example in which, as shown in Figure 4A, embankment material transported by a dump truck 2B (construction machinery) is spread out by a bulldozer 2A (construction machinery), then as shown in Figure 4B, the ends of the slope are shaped by a backhoe 2C (construction machinery), and then as shown in Figure 4C, the surface is compacted by a vibratory roller 2D (construction machinery), and these processes are repeated to form multiple layers and construct an embankment.

[0048] In this embodiment, the workpiece is so-called embankment material, such as soil or a cement mixture. The embankment material, transported and unloaded by a dump truck 2B, is spread by a bulldozer 2A to a predetermined target thickness (target shape), for example, 25 cm, that is, to raise the height by 25 cm. After that, the ends are shaped into a predetermined shape, which is the target shape, by a backhoe 2C. Then, it is compacted by a vibratory roller 2D for a predetermined number of times (for example, 6 times), which is the target specification.

[0049] Therefore, the work planned in the work planning section 11B is as follows: in the case of the bulldozer 2A, it is to spread the embankment material to a target shape (spread thickness of 25 cm) within a predetermined range; in the case of the backhoe 2C, it is to shape the edges of the predetermined range where the embankment material has been spread to a target shape (a predetermined angle (e.g., 45 degrees)); and in the case of the vibratory roller 2D, it is to compact the surface of the embankment material that has been spread within a predetermined range and whose edges have been shaped by moving it back and forth for a target specification (a predetermined number of times (e.g., 6 times)).

[0050] Figure 5 shows three work areas A, B, and C, where leveling is carried out sequentially by bulldozer 2A (construction machinery). Specifically, once leveling is completed in the first work area A, bulldozer 2A moves to the second work area B and begins leveling work in the second work area B. After leveling by bulldozer 2A is completed in the first work area A, backhoe 2C enters and begins shaping the edge of the slope.

[0051] Once the leveling work in the second work area B is complete, bulldozer 2A moves to the third work area C and begins leveling work there. After bulldozer 2A has finished leveling in the second work area B, backhoe 2C, which has finished working in the first work area A, enters the area and begins shaping the edge of the slope. Also, after backhoe 2C has finished shaping the edge of the first work area A, vibratory roller 2D enters the area and begins compaction.

[0052] In this way, the height of the dam increases in the order of the first work area A, the second work area B, and the third work area C.

[0053] Here, from the standpoint of efficiency and safety, it is preferable to have all the work in each work area A, B, and C performed by construction machine 2 under automated operation. However, for example, leveling by bulldozer 2A tends to have reduced work accuracy near the edges (slopes) and near the boundaries between work areas A, B, and C. Therefore, in these areas, it is necessary to ensure work accuracy through manual operation by an operator.

[0054] Therefore, the work area setting unit 11A of the control unit 11 described above sets a certain width of area including the edges of each work area A, B, and C as manual operation work areas A2, B2, and C2, where work is performed by the manually operated construction machine 2, for example, as shown in Figure 5. In addition, the area enclosed on three sides by the manual operation work area A2 is set as the automatic operation work area A1, where work is performed by the automatically operated construction machine 2, and the areas sandwiched between the manual operation work areas B2 and C2 are set as the automatic operation work areas B1 and C1, where work is performed by the automatically operated construction machine 2. In other words, each work area A, B, and C is divided into two areas: the automatic operation work areas A1, B1, C1 and the manual operation work areas A2, B2, C2. Thus, the manual operation work areas A2, B2, and C2 are set outside the automatic operation work areas A1, B1, C1. In other words, the automated operation areas A1, B1, and C1 are set inside the manual operation areas A2, B2, and C2. Note that there may be overlapping areas between the automated operation area A1 and the manual operation area A2.

[0055] Furthermore, the work planning unit 11B of the control unit 11, as described above, sets the automatic operation start position P1 and the automatic operation end position P2 based on the leveling work performed within the automatic operation work area A1, as shown in Figure 5. For example, the automatic operation start position P1 is set according to the position where the dump truck 2B, which transports the embankment material, first unloads. The position where the dump truck 2B unloads is set separately according to the size of the first work area A, the thickness of the embankment, the load capacity of the dump truck 2B, etc.

[0056] The automated driving work completion position P2 may be set appropriately within the automated driving work area A1 according to the unloading position and unloading sequence of the dump truck 2B, which are set separately within the first work area A, or it may not be set in advance and its position may be changed in accordance with the progress of work within the automated driving work area A1, for example, in accordance with changes in the unloading position and unloading sequence of the dump truck 2B. Furthermore, the work planning unit 11B of the control unit 11 described above may set the automated driving work start position P1 and the target shape of the embankment material (work to be done) (leveling thickness (for example, 25 cm)).

[0057] In this way, once the work planning unit 11B sets the work content to be performed in each operating work area A1, A2, the schedule generation unit 11C generates a schedule of work to be performed at each work site 1A, 1B, and 1C, as shown in Figure 6. The schedule shown in Figure 6 is an excerpt of the work schedule to be performed at the two work sites 1A and 1B, showing the scheduled work to be performed by the bulldozer 2A (leveling machine) in automatic operation mode and the scheduled work to be performed in manual operation mode.

[0058] For example, as shown in Figure 6, by setting the time when the bulldozer 2A (leveling machine) is in manual operation mode so that it does not overlap at the two work sites 1A and 1B, it becomes possible for one operator to remotely control the bulldozers 2A deployed at different work sites 1A and 1B using the remote control unit 20.

[0059] Next, we will explain the process of leveling the automated work area A1 and the manually operated work area A2, which are set up within the work site 1A as shown in Figure 5, using the bulldozer 2A, with reference to the flowchart shown in Figure 7.

[0060] First, in step S10, the work management unit 10 sets up an automatic operation work area A1 and a manual operation work area A2 within the work site 1A using the work area setting unit 11A of the control unit 11, as described above (work area setting step).

[0061] Next, in step S11, the work management unit 10 sets the work details, including the automatic operation start position P1, the automatic operation end position P2, and the target value of the embankment material (work to be worked on), using the work planning unit 11B of the control unit 11 as described above (work planning process). Note that, as described above, the automatic operation end position P2 may not be set at this point, but may be set as the work progresses after the automatic operation has started.

[0062] Once the work area and work details are set in this manner, the work management unit 10 transmits the automatic operation start position P1 to the bulldozer 2A in manual operation mode in the subsequent step S12. If the bulldozer 2A is manually operated by an operator via the remote control unit 20, the automatic operation start position P1 is transmitted to the remote control unit 20. If the bulldozer 2A is manually operated by an operator boarding the bulldozer 2A, the automatic operation start position P1 is transmitted to a terminal equipped on the construction machine 2 or to a tablet terminal held by the operator.

[0063] The work details set in step S11 are generated as a work schedule (work plan) by the schedule generation unit 11C described above, and displayed via the notification unit 11D on the display unit 13, the display units 33 of each site management unit 30, and the display unit 22 of the remote control unit 20 (displayed process).

[0064] The schedule displayed on each of the display units 13, 22, and 33 includes the automatic operation time during which the bulldozer 2A performs work automatically and the manual operation time during which it performs work manually. Furthermore, each of the display units 13, 22, and 33 also displays whether the bulldozer 2A is in an automatic operation state or a manual operation state. For example, by looking at the display unit 22 of the remote control unit 20, the operator can easily determine which of the work sites 1A, 1B, and 1C has a bulldozer 2A that is in a state where it can be operated manually, i.e., a state where it can be remotely controlled.

[0065] Upon receiving information regarding the automated operation start position P1, the operator operates the control unit 27 of the remote control device 24 or the existing control unit 49 of the bulldozer 2A to move the bulldozer 2A from the parking position (current position) to the automated operation start position P1 (step S13).

[0066] As shown in Figure 5, when the bulldozer 2A reaches the automated operation start position P1, the operator performs an operation to send a movement completion signal to the work management unit 10 to inform it that the movement is complete (step S14).

[0067] Upon receiving the movement completion signal, the work management unit 10 acquires the current position information of the bulldozer 2A, and the determination unit 11E determines whether or not the bulldozer 2A has reached a predetermined position, i.e., the automatic operation start position P1 (step S15: determination step).

[0068] In step S15, when it is determined that the bulldozer 2A has reached a predetermined position, the work management unit 10 switches the operating state of the bulldozer 2A from manual operation to automatic operation using the operation switching unit 11F (operation switching process). If the manual operation of the bulldozer 2A is performed by an operator riding on the bulldozer 2A, the operation state of the bulldozer 2A is switched after it is confirmed, for example, from the positional relationship between the tablet terminal held by the operator and the bulldozer 2A that the operator has dismounted from the bulldozer 2A and moved a predetermined distance or more away.

[0069] On the other hand, if it is determined in step S15 that the bulldozer 2A has not yet reached the predetermined position, the work management unit 10 instructs the operator controlling the bulldozer 2A to correct the position of the bulldozer 2A. Upon receiving the instruction to correct the stopping position, the operator moves the bulldozer 2A according to the instruction and then transmits a movement completion signal again (step S14).

[0070] In step S15, when the operating state of the bulldozer 2A is switched from manual operation to automatic operation, the work management unit 10 transmits a start command to the bulldozer 2A to start automatic (autonomous) operation within the automatic operation work area A1, and also transmits the details of the work to be performed within the automatic operation work area A1, such as the unloading position of the dump truck 2B and the direction and range of leveling around the unloading position (step S16).

[0071] Furthermore, in step S15, when it is determined that the bulldozer 2A has reached a predetermined position, i.e., the automatic operation start position P1, or when the operation switching unit 11F switches the operating state of the bulldozer 2A from manual operation to automatic operation, the fact that the automatic operation of the bulldozer 2A has started is notified via the notification unit 11D to the display unit 13, the display unit 33 of each site management unit 30, the display unit 22 of the remote control unit 20, and a display unit (not shown) of the bulldozer 2A (construction machine 2) (notification process). For this reason, for example, by looking at the display unit 22 of the remote control unit 20, the operator can easily understand which bulldozer 2A deployed at which work site 1A, 1B, or 1C has become ready for automatic operation.

[0072] Upon receiving the start command, the bulldozer 2A begins work in automatic operation and performs the work according to the received work instructions. Specifically, the surrounding detection unit 44 detects the position of the dump truck 2B and the shape of the embankment material (work to be done) unloaded from the dump truck 2B, and starts leveling work in automatic (autonomous) operation according to the shape of the embankment material (step S17).

[0073] Within the automated work area A1, the bulldozer 2A spreads the embankment material (workpiece) detected by the surrounding detection unit 44 in a predetermined direction and range so that the spreading thickness of the embankment material (workpiece) reaches a set target value (for example, 25 cm). The spreading thickness of the embankment material is approximately equal to the difference between the height (altitude) of the bulldozer 2A before spreading and the height (altitude) of the bulldozer 2A after spreading, and is calculated using a known method based on the detected values ​​of the position acquisition unit 42 and the state detection unit 43.

[0074] The position where work is completed within the automated work area A1 (autonomous work completion position P2) is determined within the automated work area A1 according to the unloading position and order of the dump truck 2B. It is the position where the leveling work within the automated work area A1 is completed and the bulldozer 2A stops, that is, the position where the bulldozer 2A stops simultaneously with the completion of the leveling work within the automated work area A1. Therefore, if there are any changes to the unloading position or order of the dump truck 2B, the automated work completion position P2 will also be changed accordingly. Alternatively, the automated work completion position P2 may be set in advance, and the bulldozer 2A may be automatically driven toward the automated work completion position P2 after the leveling work within the automated work area A1 is completed, regardless of the unloading position or order of the dump truck 2B.

[0075] Once the bulldozer 2A has completed moving to the automated work completion position P2, it sends a movement completion signal to the work management unit 10 (step S18).

[0076] Upon receiving the movement completion signal, the work management unit 10 acquires the current position information of the bulldozer 2A, and the determination unit 11E determines whether the bulldozer 2A has reached a predetermined position, i.e., the automatic operation completion position P2 (step S19: determination process). The determination unit 11E also determines whether the work on the embankment material (work to be done) has reached a target value, for example, whether the height (altitude) of the bulldozer 2A has risen by the target leveling thickness.

[0077] In step S19, when the bulldozer 2A reaches a predetermined position and it is determined that the work on the embankment material has reached the target value, the work management unit 10 switches the operating state of the bulldozer 2A from automatic operation to manual operation using the operation switching unit 11F (operation switching process).

[0078] Furthermore, in step S19, when the bulldozer 2A reaches a predetermined position, i.e., the automatic operation completion position P2, and the determination unit 11E determines that the work on the embankment material has reached the target value, or when the operation switching unit 11F switches the operating state of the bulldozer 2A from automatic operation to manual operation, the completion of the automatic operation of the bulldozer 2A is notified via the notification unit 11D to the display unit 13, the display unit 33 of each site management unit 30, the display unit 22 of the remote control unit 20, and an unshown display unit on the bulldozer 2A (construction machine 2) (notification process). For this reason, for example, by looking at the display unit 22 of the remote control unit 20, the operator can easily understand which bulldozer 2A deployed at which work site 1A, 1B, or 1C has become capable of manual operation, i.e., capable of remote operation.

[0079] On the other hand, in step S19, if it is determined that the bulldozer 2A has not yet reached the predetermined position or that the work on the embankment material has not reached the target value, the work management unit 10 instructs the bulldozer 2A, which is in automatic operation mode, to correct its position or perform the work again. Upon receiving an instruction to correct the stopping position, the bulldozer 2A moves according to the instruction and then transmits a movement completion signal again. Upon receiving an instruction to perform work again on the embankment material, the bulldozer 2A resumes automatic operation, performs the necessary work, and then transmits a work completion signal again (step S18).

[0080] In step S19, when the operating state of the bulldozer 2A is switched from automatic operation to manual operation, the work management unit 10 transmits a start command to the operator of the bulldozer 2A to begin work in the manual operation work area A2, along with the details of the work to be performed in the manual operation work area A2 (step S20). Specifically, the shape and extent of the manual operation work area A2, the automatic operation start position P1 in the automatic operation work area B1 of the next work area, the second work area B, etc. are transmitted as work details.

[0081] Upon receiving the work instructions, the operator operates the bulldozer 2A and begins leveling work in the manually operated work area A2 (step S21). Once the work in the manually operated work area A2 is completed, the operator moves the bulldozer 2A to the automated work start position P1 in the automated work area B1 of the second work area B, which is the next work area.

[0082] When the bulldozer 2A reaches the automated work start position P1 in the automated work area B1, the operator performs an operation to send a move completion signal to the work management unit 10 to inform it that the move is complete (step S22).

[0083] Upon receiving the movement completion signal, the work management unit 10 acquires the current position information of the bulldozer 2A, and the determination unit 11E determines whether or not the bulldozer 2A has reached a predetermined position, i.e., the automated operation start position P1 in the automated operation work area B1 (step S23: determination step).

[0084] In step S23, when it is determined that the bulldozer 2A has reached a predetermined position, the work management unit 10 switches the operating state of the bulldozer 2A from manual operation to automatic operation using the operation switching unit 11F (operation switching process).

[0085] On the other hand, if it is determined in step S23 that the bulldozer 2A has not yet reached the predetermined position, the work management unit 10 instructs the operator of the bulldozer 2A to correct the position of the bulldozer 2A, similar to step S15 described above.

[0086] In step S23, when the operating state of the bulldozer 2A is switched from manual operation to automatic operation, the work management unit 10 transmits to the bulldozer 2A the details of the work to be performed within the automatic operation work area B1, similar to step S16 described above.

[0087] From this point onward, the processes from step S16 to step S23, i.e., the work performed by both automated and manual operation, are repeated until the leveling work within the pre-planned work area is completed, for example, until the work in the third work area C shown in Figure 5 is completed.

[0088] Furthermore, for the slope edge shaping work by the backhoe 2C and the compaction work by the vibratory roller 2D, which follow the leveling work by the bulldozer 2A, the work area and work content are set in the same way as for the leveling work by the bulldozer 2A, and the work is repeatedly performed in both automatic and manual operation modes. Whether the work on the embankment material (work to be done) has reached the target value is determined, for example, by whether the angle of the compaction attachment is at the target angle (e.g., 45 degrees) in the case of the backhoe 2C, and for example, by whether the trajectory of the vibratory roller 2D moving across the surface of the embankment material, which is determined based on the detected value of the position acquisition unit 42, is the target trajectory (e.g., 6 compactions). Note that the edge shaping work by the backhoe 2C may be performed by manual operation only, and the compaction work by the vibratory roller 2D may be performed by automatic operation only.

[0089] In this way, a multi-layered dam is constructed as each construction machine 2A, 2B, 2C, and 2D sequentially performs its planned work.

[0090] According to the above embodiments, the following effects are achieved.

[0091] According to the work management system 100 and work management method of this embodiment, the operating state of the construction machine 2 is switched only when it is determined that the construction machine 2 has reached a preset automatic operation start position P1 or automatic operation end position P2. In other words, construction machine 2 in automatic operation state and construction machine 2 in manual operation state will not be mixed in the same work area. As a result, it becomes possible to efficiently perform work in automatic operation work areas A1, B1, C1 and work in manual operation work areas A2, B2, C2, and safety can be ensured as collisions between construction machines 2 can be avoided.

[0092] Furthermore, according to the work management system 100 and work management method of this embodiment, when the construction machinery 2 deployed at each work site 1A, 1B, and 1C is switched to manual operation mode, it can be remotely operated from a remote control unit 20 located away from each work site 1A, 1B, and 1C. In other words, the operator remotely controlling the construction machinery 2 from the remote control unit 20 can operate the construction machinery 2 deployed at multiple work sites 1A, 1B, and 1C. This reduces the number of operators stationed at each work site 1A, 1B, and 1C. In addition, since operators no longer need to be on board the construction machinery 2, work safety can be improved.

[0093] Furthermore, according to the work management system 100 and work management method of this embodiment, the time (time) when the construction machine 2 is in manual operation mode is set so that it does not overlap as much as possible between each work site 1A, 1B, and 1C. As a result, the operator who remotely controls the construction machine 2 with the remote control unit 20 can sequentially operate the construction machines 2 deployed at multiple work sites 1A, 1B, and 1C, and as a result, the number of operators required can be reduced.

[0094] Furthermore, according to the work management system 100 and work management method of this embodiment, the result of the determination unit 11E determining that the work has been completed, and whether the operating status of each construction machine 2 is in an automatic operation state or a manual operation state, are displayed on the display unit 13, the display unit 33 of each site management unit 30, and the display unit 22 of the remote control unit 20. This makes it easy to grasp the progress of the work, and for example, by looking at the display unit 22 of the remote control unit 20, the operator can easily determine which construction machine 2 is in a state where it can be operated manually, that is, in a state where it can be remotely operated.

[0095] Furthermore, the following modifications are also within the scope of the present invention, and it is possible to combine the configurations shown in the modifications with the configurations described in the embodiments described above, or to combine the configurations described in the following different modifications.

[0096] In the above embodiment, the work management system 100 manages the work of construction machinery 2 involved in civil engineering work to construct the embankment. Alternatively, the work management system 100 may manage the work of construction machinery 102A involved in excavation work, as shown in Figure 8, and the civil engineering work carried out at each work site 1A, 1B, and 1C managed by the work management system 100 may be of different forms, such as embankment work and excavation work.

[0097] The example shown in Figure 8 involves excavating the ground with a bulldozer 102A (construction machine) to form an excavation bed, then compacting the slope with a backhoe (not shown), and repeating these steps to form a construction base surface of a predetermined width. In the example shown in Figure 8, the workpiece is the ground, which is gradually excavated by the bulldozer 102A (construction machine) until the height of the excavation bed reaches a predetermined height (target shape), and then the slope is compacted by the backhoe to the predetermined shape, which is the target shape. The excavated soil is transported away as needed by a dump truck (not shown).

[0098] In this example, the work planned in the work planning section 11B is, in the case of the bulldozer 102A, to excavate within a predetermined range so that the height of the excavation bed is reduced by a predetermined amount, and in the case of the backhoe, to compact the slope within a predetermined range to a target shape (a predetermined angle (for example, 45 degrees)).

[0099] Figure 9 shows three work areas A, B, and C where excavation is carried out sequentially by a bulldozer 102A (construction machine). Specifically, once excavation work in the first work area A is completed, the bulldozer 102A moves to the second work area B and begins excavation work in the second work area B. After the excavation work by the bulldozer 102A is completed in the first work area A, a backhoe enters and begins compacting the slope.

[0100] Once the excavation work in the second work area B is completed, bulldozer 102A will move to the third work area C and begin excavation work there. After the excavation work by bulldozer 102A is completed in the second work area B, the backhoe that has finished its work in the first work area A will enter and begin compacting the slope.

[0101] In this manner, the height of the excavation bed decreases in the order of the first work area A, the second work area B, and the third work area C, and these operations are repeated until the height of the excavation bed reaches the construction base level.

[0102] While it would be preferable from the standpoint of efficiency and safety to have all the work in each work area A, B, and C performed automatically by the construction machine 102A, the accuracy of excavation by the bulldozer 102A tends to decrease near the toe of the slope. Therefore, in this section, it is necessary to ensure accuracy through manual operation by an operator.

[0103] Therefore, in such excavation work, the work area setting unit 11A of the control unit 11 described above sets the area near the toe of the slope as a manually operated work area A2 where work is performed by a manually operated construction machine 102A, as shown in Figure 9, and sets the remaining area as an automatically operated work area A1 where work is performed by an automatically operated construction machine 102A. In other words, each work area A, B, and C is divided into two areas: an automatically operated work area A1, B1, C1 and a manually operated work area A2, B2, C2. Note that there may be overlapping areas between the automatically operated work area A1 and the manually operated work area A2.

[0104] In this case as well, similar to the above embodiment, the construction machine 102A completes the predetermined civil engineering work by repeatedly performing tasks under automated driving and tasks under manual driving.

[0105] Therefore, similar to the above embodiment, it becomes possible to efficiently perform work in the automated work areas A1, B1, and C1, as well as work in the manual work areas A2, B2, and C2, and safety can be ensured as collisions between construction machines 2 can be avoided.
