[0010] Hereinafter, a work management method according to an embodiment of the present invention will be described with reference to the drawings.

[0011] First, a work management system 100 suitable for carrying out a work management method according to an embodiment of the present invention will be described with reference to FIGS.

[0012] As shown in Fig. 1, the work management system 100 is a system constructed to collectively manage work performed by multiple construction machines 2 that are capable of both automatic and manual operation and are 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 more than several hundred kilometers apart from one another. Note that the multiple work sites 1A, 1B, and 1C may also be multiple work areas set up within a single civil engineering construction site.

[0013] Furthermore, the work sites 1A, 1B, and 1C are not limited to civil engineering work sites within Japan, but may be overseas civil engineering work sites or civil engineering work sites outside the Earth, such as on the surface of the moon. Furthermore, the number of work sites 1A, 1B, and 1C to be managed may be any number, provided that it is two or more.

[0014] The work management system 100 comprises a site management unit 30 installed at each of the work sites 1A, 1B, 1C (work area), and a work management unit 10 that manages the work status of multiple construction machines 2 deployed at each of the work sites 1A, 1B, 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 line. The following describes a case where the work management system 100 manages the work of construction machines 2 involved in civil engineering work to build a bank body such as a trapezoidal dam by piling up embankment material such as CSG (Cemented Sand and Gravel).

[0015] The work management unit 10 is mainly composed of a microcomputer equipped with a CPU (Central Processing Unit) as the control unit 11, ROM (Read Only Memory) and RAM (Random Access Memory) as the memory unit 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 of calculations performed by the control unit 11 and the work status of each work site 1A, 1B, 1C in real time, and an input unit 14 that accepts input operations from an operator who manages the work. The memory unit 15 pre-stores programs executed by the control unit 11 and data necessary for executing the programs, and sequentially stores the results of calculations performed by the control unit 11. Specific control performed by the control unit 11 will be described later.

[0016] The work management unit 10 is installed in a location away from each of the work sites 1A, 1B, 1C in order to collectively manage the work of the multiple construction machines 2 deployed at each of the work sites 1A, 1B, 1C. Note that the work management unit 10 may be installed at any of the work sites 1A, 1B, 1C.

[0017] Next, the site management unit 30 installed at each work site 1A, 1B, 1C and the construction machines 2 deployed at each work site 1A, 1B, 1C will be described with reference to Fig. 2. Fig. 2 shows a schematic configuration of one work site 1A among the multiple work sites 1A, 1B, 1C.

[0018] Similar to the work management unit 10, the site management unit 30 is mainly composed of a microcomputer equipped with a CPU (Central Processing Unit) as a control unit 31, a ROM (Read Only Memory) and RAM (Random Access Memory) as a memory unit 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 the operator managing the work.

[0019] The site management unit 30 also includes a transmitter / receiver 36 that exchanges data with each construction machine 2, and an imaging unit 37 that captures images of the work site 1A. The transmitter / receiver 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 the same configuration.

[0020] The construction machine 2 deployed at the work site 1A is configured to be capable of automatic (autonomous) operation by equipping a general-purpose construction machine with a position acquisition unit 42 capable of receiving signals from GPS satellites and the like that make up the Global Navigation Satellite System (GNSS), a state detection unit 43 that can detect acceleration, angular velocity, and geomagnetism, a surroundings detection unit 44 that can detect surrounding obstacles, etc., 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 each of these units.

[0021] 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 status detection unit 43 is a so-called inertial measurement unit (IMU) that is a unit that includes an acceleration sensor, a gyro sensor, a barometric pressure sensor, and a geomagnetic sensor that can detect the status of the construction machine 2. The status detection unit 43 also includes an engine operation detection sensor that detects the operating status, i.e., the status of the construction machine 2, and a voltmeter and ammeter that detect the voltage and current of the battery and electrical components of the construction machine 2. The surroundings detection unit 44 is a three-dimensional range sensor such as a laser scanner that can recognize the surrounding space by emitting light and measuring the light reflected by an object, a so-called 3D-LiDAR (light detection and ranging) sensor, or a radar sensor (RADAR) that can measure the distance to a measurement target using radio waves. The transmission / reception unit 45 is a wireless communication means similar to the transmission / reception unit 36 ​​of the site management unit 30.

[0022] 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 in the construction machine 2. By doing so, the control unit 41 detects the state and shape of the workpiece, such as embankment material, from the results detected by the periphery detection unit 44 and confirms the safety of the surroundings, while also confirming its own position and attitude from the results detected by the position acquisition unit 42 and the state detection unit 43, thereby controlling the steering and other operations of the construction machine 2 so that it autonomously performs the instructed work. Note that the automatic (autonomous) operation of the construction machine 2 may be performed by sequence control, which controls based on a predetermined order or judgment, or by feedback control, which controls based on the shape and amount of the workpiece, such as embankment material, measured by the periphery detection unit 44, or by a combination of these types of control.

[0023] Here, the existing control unit 48 controls the steering, engine output, etc. of the construction machine 2 in response to the operator operating existing operation units 49 such as handles and levers that are pre-installed on the construction machine 2 for manual steering, etc. In other words, by generating a signal in the control unit 41 that is equivalent to the signal generated when the existing operation unit 49 is operated 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, and to operate it by remote control.

[0024] In addition, since the existing operation unit 49 remains installed on the construction machine 2, it is possible for an operator to manually operate the construction machine 2 by getting on board.

[0025] Furthermore, in order to enable an operator to remotely control the construction machine 2, the construction machine 2 is further provided with an imaging unit 46 capable of capturing images of the situation at the work site 1A visible from the cab, and a sound collecting device (not shown) that picks up working sounds of the construction machine 2. The imaging unit 46 is, for example, a stereo camera capable of capturing images of the situation all around the construction machine 2, and it is preferable that the imaging direction changes according to the direction and movement of the head of the operator who operates the remote control unit 20 (described below).

[0026] In this way, the construction machine 2 is capable of automatic (autonomous) operation, and is configured to be manually operated with an operator on board, or manually operated by an operator operating in a remote location. In other words, the manual operation of the construction machine 2 described below includes a case where an operator operates the construction machine 2 by boarding the construction machine 2, and a case where an operator does not board the construction machine 2 but operates the construction machine 2 by remote control from the remote control unit 20 described below.

[0027] Examples of construction machines 2 that are configured to be capable of automatic and manual operation include bulldozers, dump trucks, vibratory rollers, and backhoes, and work performed by these different types of construction machines 2 deployed at the work site 1A is managed by the site management unit 30, and is also managed by the work management unit 10 via the site management unit 30. Note that although the configuration of the existing operation unit 49 differs depending on the type of construction machine 2, the configuration required to enable automatic operation and remote control is approximately the same.

[0028] The work management system 100 further includes a remote control unit 20 for remotely controlling the construction machines 2 deployed at the respective work sites 1A, 1B, 1C from locations distant from the respective work sites 1A, 1B, 1C.

[0029] 1, the remote control unit 20 is mainly composed 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 in real time a schedule for remote control and the work status of the remotely controlled construction machine 2. The remote control unit 20 may be directly connected to the control unit 11 of the work management unit 10, or may be connected to the work management unit 10 via a communication network 50. The remote control unit 20 may be installed in the same location as the work management unit 10, or may be installed in a location away from the work management unit 10 or at one of the work sites 1A, 1B, 1C.

[0030] The remote control device 24 is provided with an operation 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 provided on the construction machine 2 and the details of the work, and a speaker (not shown) that outputs sounds around the construction machine 2, and the operation of these is controlled by a control unit 25 that is mainly composed of a CPU (Central Processing Unit). The display unit 26 may be, for example, a head-mounted display worn by the operator.

[0031] Next, the control executed by the control unit 11 of the work management unit 10 in the work management system 100 configured as above will be described with reference to FIG.

[0032] As shown in Figure 3, the control unit 11 has a work area setting unit 11A that sets work areas within each work site 1A, 1B, 1C where multiple construction machines 2, including automatically operable construction machines, will each perform construction work in turn based on three-dimensional data such as CIM (Construction Information Modeling) data for each work site 1A, 1B, 1C; a work planning unit 11B that plans the content of the work to be performed by each construction machine 2 in each work area set by the work area setting unit 11A based on the specifications of each construction machine 2; a notification unit 11C that displays each work area set by the work area setting unit 11A 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; and a judgment unit 11D that judges the completion of the work planned by the work planning unit 11B based on the position information of each construction machine 2 and signals transmitted from each construction machine 2.

[0033] Three-dimensional data such as CIM data used in the work area setting unit 11A is stored in advance in the storage unit 15 or the storage unit 35 of each site management unit 30. The data used in the work area setting unit 11A may be input by an operator via the input unit 14.

[0034] The work area setting unit 11A sequentially sets a preceding work area where a preceding construction work is performed and a following work area where a following construction work is performed after the preceding construction work is performed within each work site 1A, 1B, 1C (work area). Specific examples of the preceding construction work and the following construction work will be described later.

[0035] In the work area setting unit 11A, the following work area is set within the range of the area of ​​the preceding work area for which the determination unit 11D has determined that the preceding construction work has been completed, but within a range that does not exceed the area of ​​the preceding work area, and the preceding work area is set adjacent to the preceding work area for which the determination unit 11D has determined that the preceding construction work has been completed, but does not overlap with this area. In this way, the work area setting unit 11A sequentially sets work areas (preceding work area, following work area) within each work site 1A, 1B, 1C in which multiple construction machines 2, including automatically operable construction machines, will each perform construction work in turn, in response to the completion of construction work.

[0036] The specifications of each construction machine 2 used in the work planning unit 11B are input in advance by an 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 and the like are input as specifications; if it is a dump truck, the maximum load capacity and traveling speed; and if it is a vibratory roller, the roller width and the like are input as specifications.

[0037] Furthermore, when the work content is planned in the work planning unit 11B, of the construction machines 2 deployed at each work site 1A, 1B, 1C, construction machines 2 undergoing inspection or repair are excluded from the plan, and only construction machines 2 that are ready to perform work are included in the plan. Whether or not a construction machine 2 is ready to work is input at any time by the operator via the input unit 34 of the site management unit 30. Furthermore, since each construction machine 2 originally has an abnormality detection function that detects abnormalities in the actuators that operate the work machine based on hydraulic oil pressure sensors and hydraulic oil temperature sensors (not shown), it may also be possible to determine at any time whether or not a construction machine 2 is ready to work based on the presence or absence of an abnormality transmitted from each construction machine 2.

[0038] The work content planned by the work planning unit 11B includes the automatic driving work content in which the construction machine 2 performs work by automatic driving within the work area, specifically the start position where the automatic driving work begins, the end position where the automatic driving work ends, and the route from the start position to the end position, and these are converted into data and sent to the construction machine 2 in charge of the work via the site management unit 30. The automatic driving work content is, for example, the content of work to be done on the work object such as embankment material, and includes information about the work range in which the work will be performed and target values ​​within the work range (target shape, target specifications), and is set respectively according to the work to be performed by each construction machine 2, as described below. By setting the work range and the target values ​​within the work range, the construction machine 2 performs work by automatic driving within the work range so as to achieve the target values.

[0039] The work content planned in the work planning unit 11B also includes manual operation work content in which the construction machine 2 is manually operated within the work area. When an operator gets on the construction machine 2, the work content planned in the work planning unit 11B is sent via the site management unit 30 to a terminal equipped on the construction machine 2 or a tablet terminal carried by the operator, and when the operator remotely operates the construction machine 2 using the remote control unit 20, the work content is sent to the remote control device 24.

[0040] The completion status of the work determined by the determination unit 11D is displayed via the notification 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, in the same way as each work area set by the work area setting unit 11A. In addition, each display unit displays the order and time in which the work planned by the work planning unit 11B will be performed as a schedule such as a Gantt chart. This makes it easy to grasp the progress of the work.

[0041] The determination unit 11D also functions as a monitoring unit that monitors the work of each construction machine 2 within each work area set by the work area setting unit 11A. The determination unit 11D monitors whether or not a construction machine 2 performing construction work in a work area (preceding work area, following work area) set by the work area setting unit 11A is working within the work area based on the position information of the construction machine 2 acquired by the position acquisition unit 42, and if it is determined that the construction machine 2 has moved outside the work area, it issues an alarm via the notification unit 11C. The alarm is issued to the operator by, for example, flashing a warning message or the like on the display unit 13, the display unit 33 of each site management unit 30, the display unit 22 of the remote control unit 20, or a display unit (not shown) of the construction machine 2, and by emitting an alarm sound.

[0042] Note that these work area setting units 11A and the like represent the functions of the control unit 11 as virtual units, and do not mean that they physically exist. Furthermore, the above functions are part of the control executed by the control unit 11, and the control unit 11 also executes control related to functions other than these as needed.

[0043] Next, with reference to Figures 4 to 6, a specific description will be given of a work management method for a construction machine 2 performed by the work management system 100 configured as described above. The following description will be given taking as an example civil engineering work in which a bank body is constructed by repeating a plurality of construction operations to form a plurality of layers as shown in Figures 4A, 4B, 4C, and 4D.

[0044] The component work shown in FIG. 4A is a first component work in which an automatically operated bulldozer 2A (leveling machine) spreads and levels the embankment material transported by an automatically operated dump truck 2B (transport machine). The component work shown in FIG. 4B is a second component work in which a manually operated bulldozer 2C (leveling machine) further spreads and levels the embankment material, and is performed after the first component work. Furthermore, the component work shown in FIG. 4C is a third component work in which an automatically operated vibrating roller 2D (rolling machine) compacts the surface of the embankment material by rolling, and is performed after the second component work. Furthermore, the component work shown in FIG. 4D is a fourth component work in which a manually operated vibrating roller 2E (rolling machine) further compacts the surface of the embankment material by rolling, and is performed after the third component work.

[0045] That is, one layer in one working area is formed in the following manner. · Embankment materials are transported by dump truck 2B (transportation machine). The embankment material transported by bulldozers 2A and 2C (leveling machines) is spread to the specified thickness (leveling thickness 25 cm). The embankment material is compacted by using a vibrating roller 2D (rolling machine) on the surface of the laid and leveled embankment material. For example, the material is compacted by going back and forth a specified number of times (three times). - The vibrating roller 2E (compaction machine) compacts the embankment material, smoothing out any unevenness or ruts that have occurred on the surface.

[0046] In this way, a plurality of constituent tasks are carried out in order in a given work area, completing a single overall task of embankment work and constructing one layer of the embankment body.

[0047] Furthermore, by performing the second and fourth configuration tasks manually after the first and third configuration tasks are completed by automatic driving, it is possible to manually correct work areas that were not completed properly by automatic driving (partially occurring unevenness or ruts). Also, the first and third configuration tasks performed by automatic driving can be performed by large construction machinery or multiple construction machinery, while the second and fourth configuration tasks performed by manual driving can be performed by small construction machinery that requires precision, or by performing the work with fewer construction machinery, thereby saving labor and improving construction quality.

[0048] Specifically, for example, in the first configuration work, work may be performed by automatic operation using three large bulldozers 2A, while in the second configuration work, work may be performed by manual operation using one small bulldozer 2C, and in the third configuration work, work may be performed by automatic operation using five vibrating rollers 2D, while in the fourth configuration work, work may be performed by manual operation using two vibrating rollers 2E.

[0049] In this embodiment, the workpiece is so-called embankment material, such as earth and sand or a cement mixture. The embankment material transported and unloaded by the dump truck 2B is spread and leveled by the bulldozer 2A to a predetermined target thickness (target shape), for example, 25 cm, i.e., to increase the height by 25 cm. The material is then compacted by the vibratory roller 2D a predetermined number of times (for example, six times) to meet the target specifications.

[0050] Therefore, the work content planned in the work planning section 11B is, in the case of the bulldozer 2A, to spread the embankment material to the target shape (leveling thickness of 25 cm) within a specified range, and in the case of the vibratory roller 2D, to compact the surface of the embankment material spread and leveled within a specified range to the target specifications (a specified number of times, for example, 6 times) by moving back and forth over the surface.

[0051] Next, the work area set by the work area setting unit 11A when the four configuration tasks described above are performed in order will be specifically described with reference to FIGS. 5A to 5F.

[0052] Figure 5A shows a state in which the first work area A1, where the first construction work, which is the first construction work, is performed by an automatically operated bulldozer 2A, is set in an unconstructed area of ​​the planned work area A of any of the work sites 1A, 1B, 1C (work area).

[0053] When the first construction work in the first working area A1 shown in Fig. 5A is completed, as shown in Fig. 5B, a new first working area A1 is set in the unfinished area of ​​the planned work area A adjacent to the completed first working area DA1 but not overlapping with this area. At the same time, a second working area A2 in which the second construction work, the manually operated bulldozer 2C, will be performed, is set within the area of ​​the completed first working area DA1, preferably within a range not exceeding the area of ​​the first working area DA1. In the example shown in Fig. 5B, the size of the second working area A2 is the same as the size of the completed first working area DA1.

[0054] In this case, the first configuration work by the automatically operated bulldozer 2A is a preceding configuration work performed before the second configuration work by the manually operated bulldozer 2C, and the second configuration work by the manually operated bulldozer 2C is a following configuration work performed after the first configuration work by the automatically operated bulldozer 2A, with the first work area A1 being the preceding work area and the second work area A2 being the following work area.

[0055] Then, when the first construction work in the first work area A1 shown in Fig. 5B is completed, a new first work area A1 is set in the unfinished area of ​​the planned work area A, adjacent to the completed first work area DA1 but not overlapping with it, as shown in Fig. 5C. When the second construction work in the second work area A2 shown in Fig. 5B is completed, a new second work area A2 is set adjacent to the completed second work area DA2 but not overlapping with it, as shown in Fig. 5C. The new second work area A2 is set within the completed first work area DA1, preferably within a range not exceeding the first work area DA1. At the same time, a third construction work, a third construction work by the automatically operated vibrating roller 2D, is performed, and a third work area A3 is set within the completed second work area DA2, preferably within a range not exceeding the second work area DA2.

[0056] In this case, the second construction work by the manually operated bulldozer 2C is a preceding construction work performed before the third construction work by the automatically operated vibratory roller 2D, and the third construction work by the automatically operated vibratory roller 2D is a following construction work performed after the second construction work by the manually operated bulldozer 2C, with the second work area A2 being the preceding work area and the third work area A3 being the following work area. In other words, the second construction work is a following construction work relative to the first construction work, but a preceding construction work relative to the third construction work.

[0057] When the first construction work in the first work area A1 shown in FIG. 5C is completed, a new first work area A1 is set in the unfinished area of ​​the planned work area A, adjacent to the completed first work area DA1 but not overlapping with it, as shown in FIG. 5D. When the second construction work in the second work area A2 shown in FIG. 5C is completed, a new second work area A2 is set within the area of ​​the completed first work area DA1, preferably within a range not exceeding the area of ​​the first work area DA1, adjacent to the completed second work area DA2 but not overlapping with it, as shown in FIG. 5D. When the third construction work in the third work area A3 shown in FIG. 5C is completed, a new third work area A3 is set within the area of ​​the completed second work area DA2, adjacent to the completed third work area DA3 but not overlapping with it, as shown in FIG. 5D. At the same time, a fourth work area A4 where the fourth configuration work, which is the fourth configuration work using a manually operated vibrating roller 2E, is performed is set within the range of the area of ​​the third work area DA3 where the work has been completed, preferably within a range not exceeding the area of ​​the third work area DA3.

[0058] In this case, the third configuration work by the automatically operated vibrating roller 2D is a preceding configuration work performed before the fourth configuration work by the manually operated vibrating roller 2E, and the fourth configuration work by the manually operated vibrating roller 2E is a following configuration work performed after the third configuration work by the automatically operated vibrating roller 2D, with the third work area A3 being the preceding work area and the fourth work area A4 being the following work area. In other words, the third configuration work is a following configuration work relative to the second configuration work, but a preceding configuration work relative to the fourth configuration work.

[0059] Then, when each configuration task in each work area A1, A2, A3, A4 shown in Fig. 5D is completed, new work areas A1, A2, A3, A4 are set in the same manner as described above, as shown in Fig. 5E. In this example, since the fourth configuration task is the final configuration task, the fourth work area DA4 where the task has been completed becomes the work completion area.

[0060] In this way, the height of the dam body in the planned work area A increases in order from the area where all construction work has been completed.

[0061] For example, even if the second configuration work, which is the work of the manually operated bulldozer 2C, is completed, if the first configuration work, which is the preceding configuration work, has not yet been completed and the next work area for the second configuration work has not been set, the bulldozer 2C will not be able to move from the second work area DA2 where the work has been completed. If the bulldozer 2C remains in the second work area DA2 where the work has been completed, it will not be able to surrender the work area to the automatically operated vibratory roller 2D that will perform the following configuration work, and there is a risk that delays will occur in the progress of the third configuration work and the fourth configuration work, which is the subsequent configuration work.

[0062] Therefore, in such cases, it is preferable to set up a waiting area (not shown) in part of the second work area DA2 where work has been completed so that the bulldozer 2C can temporarily wait, in order to quickly vacate most of the work area for the construction machine 2 performing the following construction work.

[0063] 5B, the new first working area A1 is set adjacent to the first working area DA1 for which work has been completed. However, if there is an obstacle or the like, the new first working area A1 may be set at a location away from the first working area DA1 for which work has been completed, as shown in FIG. 5F. In other words, the location for setting the new first working area A1 may be anywhere as long as it does not overlap with the area of ​​the first working area DA1 for which work has been completed. A non-working area where no work is being performed may exist between the new first working area A1 and the first working area DA1 for which work has been completed. However, in order to shorten the travel distance of the construction machine 2 and improve the construction efficiency of the construction work, it is preferable that the new first working area A1 be set near the first working area DA1 for which work has been completed.

[0064] Furthermore, in the example shown in Figure 5B, the size of the second work area A2 is the same as the size of the first work area DA1 where work has been completed, but the second work area A2, which is the following work area, can be any size as long as it is set within the range of the area where work has been completed of the first work area A1, which is the preceding work area, and preferably does not exceed the area where work has been completed, and as shown in Figure 5F, it can also be smaller than the first work area DA1 where work has been completed.

[0065] Furthermore, the construction work is not limited to the work described above, and for example, between the second and third construction work described above, a construction work of shaping the edge of the slope with an automatically or manually operated backhoe (edge ​​shaping machine) or a construction work of driving in joint cutting plates with a vibrating joint cutting machine may be performed. Furthermore, the number of construction work is not limited to four, and may be two or five or more work as long as they are multiple work performed in sequence.

[0066] In other words, if there are N (N is a natural number greater than or equal to 2) configuration tasks that are performed in sequence, and the Nth configuration task is performed after the (N-1)th configuration task is performed, the N work areas from the first work area A1 where the first configuration task is performed to the Nth work area where the Nth configuration task is performed are sequentially set by the work area setting unit 11A to the planned work area A of the work sites 1A, 1B, 1C (work area) using the procedure described above.

[0067] Next, the flow of control executed in the work management unit 10 will be specifically described with reference to the flow diagram shown in FIG.

[0068] First, in step S10, the work management unit 10 sets, using the work area setting unit 11A of the control unit 11, a preceding work area where preceding configuration work will be performed and a following work area where following configuration work will be performed after the preceding configuration work is performed, in the planned work area A within each work site 1A, 1B, 1C (work area), as described above with reference to Figures 5A to 5F (work planning process).

[0069] In addition, in step S10, the range of each work area (preceding work area, following work area) set by the work area setting unit 11A is 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 by the notification unit 11C of the control unit 11 (display process).

[0070] Next, in step S11, the work management unit 10 uses the work planning unit 11B of the control unit 11 to plan the work content to be performed in each work area (leading work area, following work area) based on the specifications of each construction machine 2 performing each component work (leading component work, following component work) (work planning process).

[0071] Furthermore, in step S11, the work content planned by the work planning unit 11B is transmitted from the control unit 11 to each construction machine 2 together with a start command that commands the start of work (work content transmission process). When the construction machine 2 is manually operated and an operator is on board the construction machine 2, the work content and start command are transmitted via the site management unit 30 to a terminal equipped on the construction machine 2 or a tablet terminal carried by the operator, and when the construction machine 2 is manually operated and an operator remotely controls the construction machine 2 using the remote control unit 20, the work content and start command are transmitted to the remote control device 24.

[0072] Upon receiving the work content and start command, each construction machine 2 starts construction work based on the work content in each assigned work area.

[0073] When each construction machine 2 starts construction work, the work management unit 10 monitors the work of each construction machine 2 using the monitoring function of the determination unit 11D of the control unit 11 in the following step S12 (monitoring step).

[0074] When it is determined that the construction machine 2 has moved outside the assigned work area, an alarm is issued via the notification unit 11C as described above. Furthermore, if the construction machine 2 that has moved outside the work area is automatically operated, the operation of that construction machine 2 is stopped on the spot to ensure safety. If the construction machine 2 that has moved outside the work area is manually operated, a warning is issued to the operator of that construction machine 2 to return to the designated work area, and if, for example, the construction machine 2 does not return to the work area within a predetermined time, the operation of that construction machine 2 is stopped on the spot to ensure safety.

[0075] Subsequently, in step S13, the work management unit 10 determines, by the determination unit 11D of the control unit 11, whether or not the configuration work in any of the work areas has been completed (work completion determination step).

[0076] Whether or not the construction work by the construction machine 2 has been completed is determined, for example, by whether or not a work completion signal has been received from the construction machine 2, or whether or not it has been confirmed that the construction machine 2 has reached a position designated as the work completion position within the work area.

[0077] In addition, instead of or in addition to the above determination, whether the construction work by the automatically operated construction machine 2 has been completed may be determined by whether the work by each construction machine 2 on the embankment material (work object) has reached a target value. In the case of a bulldozer 2A, this may be determined by whether the leveling thickness of the embankment material has reached a set target value (e.g., 25 cm), for example, by whether the height (altitude) of the bulldozer 2A obtained from the detection values ​​of the position acquisition unit 42 and the status detection unit 43 has increased by the amount of the target leveling thickness within the work area. In the case of a vibratory roller 2D, this may be determined by, for example, whether the trajectory of the vibratory roller 2D moving on the surface of the embankment material, obtained based on the detection values ​​of the position acquisition unit 42, is the target trajectory (e.g., six compactions). In the case of a backhoe (not shown) that shapes the ends of slopes, this may be determined by, for example, whether the angle of the compaction attachment is the target angle (e.g., 45 degrees).

[0078] In step S13, if it is determined that the configuration work in any of the work areas has been completed, the process proceeds to step S14, and the judgment unit 11D of the control unit 11 determines whether all of the configuration work planned in the planned work area A has been completed.

[0079] On the other hand, if it is determined in step S13 that construction work has not been completed in any of the work areas, the process returns to step S12, and monitoring of the work of each construction machine 2 continues.

[0080] If it is determined in step S14 that all of the construction work scheduled in the planned work area A has been completed, the control is temporarily terminated since there are no more work areas to be newly set by the work area setting unit 11A.

[0081] On the other hand, if all the construction work scheduled in the planned work area A has not yet been completed, the process returns to step S10, and the work area setting unit 11A sets a work area where the next construction work will be performed.

[0082] Through the above process, each work area (leading work area, following work area) is set in sequence in the planned work area A within each work site 1A, 1B, 1C (work area), and the embankment is gradually constructed as each construction machine 2 performs its respective prescribed construction work in each work area.

[0083] According to the above embodiment, the following effects are achieved.

[0084] As described above, the work management method of this embodiment is a work management method using a work management system 100 that manages N configuration tasks in a predetermined work site 1A, 1B, 1C (work area) in which the (N-1)th (N is a natural number greater than or equal to 2) configuration task is performed by a plurality of construction machines 2, including automatically operable construction machines 2, and then the Nth configuration task is performed in sequence.The method includes a work area setting process that sequentially sets N work areas within the work area, from a first work area A1 where the first configuration task is performed to an Nth work area where the Nth configuration task is performed, and a work completion determination process that determines the completion of (N-1) configuration tasks from the first configuration task performed in the first work area A1 to the (N-1)th configuration task performed in the (N-1)th work area. Then, either the (N-1)th construction work or the Nth construction work is performed by an automatically operated construction machine 2, and in the work area setting process, the Nth work area is set within the range of the area of ​​the (N-1)th work area in which it is determined in the work completion determination process that the (N-1)th construction work has been completed, preferably within a range not exceeding the area of ​​the (N-1)th work area, and the new (N-1)th work area is set adjacent to the (N-1)th work area in which it is determined in the work completion determination process that the (N-1)th construction work has been completed, but so as not to overlap with this area.

[0085] As described above, according to the work management method of this embodiment, the leading work area where leading construction work is performed and the trailing work area where trailing construction work is performed after the leading construction work are set completely separately. This prevents a construction machine 2 performing leading construction work and a construction machine 2 performing trailing construction work from working in the same area. Therefore, even if either the leading construction work or the trailing construction work is performed by an autonomous construction machine 2, there is no risk of the two machines interfering with the progress of the other's construction work, making it possible to perform the construction work efficiently. This improves construction efficiency when multiple construction machines, including autonomously operated construction machines, work within a specified work area. Furthermore, because autonomously operated construction machines 2 and manually operated construction machines 2 are not mixed in the same work area, collisions between the construction machines 2 are avoided, ensuring safety.

[0086] The following modified examples are also within the scope of the present invention, and it is possible to combine the configuration shown in the modified example with the configuration described in the above embodiment, or to combine the configurations described in the different modified examples below.

[0087] The work management method according to the above embodiment manages the work of construction machines 2 engaged in civil engineering work to build a bank body. Alternatively, the work management method for construction machines 2 carried out by the work management system 100 may manage the work of construction machines 2G, 2H, 2J engaged in excavation work as shown in Figures 7A, 7B, and 7C, and the civil engineering work carried out at each work site 1A, 1B, 1C managed by the work management system 100 may be different types of work, such as embankment work and excavation work.

[0088] In this modified example, a construction base surface of a predetermined width is formed in the natural ground by repeating a plurality of constituent operations as shown in Figures 7A, 7B, and 7C. The constituent operation shown in Figure 7A is a first constituent operation in which an automatically operated bulldozer 2G (excavation machine) excavates the natural ground and forms an excavation bed. The constituent operation shown in Figure 7B is a second constituent operation in which a manually operated bulldozer 2H (excavation machine) precisely excavates the vicinity of the toe of the slope, and is a constituent operation performed after the first constituent operation. Furthermore, the constituent operation shown in Figure 7C is a third constituent operation in which an automatically or manually operated backhoe 2J (slope shaping machine) compacts the slope, and is a constituent operation performed after the second constituent operation.

[0089] In other words, the excavation bed at one work site is formed in the following procedure. - The ground is excavated to a specified depth using a bulldozer 2G (excavation machine). - Use a bulldozer 2H (excavation machine) to excavate areas where excavation is insufficient, such as near the foot of a slope. · Backhoe 2J (slope shaping machine) is used to compact the slope created by excavation.

[0090] In this way, by carrying out a plurality of component tasks in sequence in a predetermined area, i.e., a work area, an excavation task, which is a single overall task, is completed, and the height of the excavation floor is lowered.

[0091] Even in this modified example, by performing the second component work by manual operation after the first component work performed by automatic operation is completed, it is possible to manually correct excavation work locations that were insufficient with automatic operation (for example, near the toe of a slope or partial unevenness). Furthermore, by performing the first component work by automatic operation using a large construction machine or multiple construction machines, and performing the second component work by manual operation using a small construction machine that requires precision, or by performing the work with a smaller number of construction machines, it is possible to save labor and improve construction quality.

[0092] Specifically, for example, in the first configuration work, work may be performed by automatic operation using three large bulldozers 2G, while in the second configuration work, work may be performed by manual operation using one small bulldozer 2H.

[0093] 7A, 7B, and 7C, the workpiece is natural ground, which is gradually excavated by bulldozers 2G and 2H so that the height of the excavation bed reaches a predetermined height (target shape), and then the slope is compacted into the predetermined target shape by a backhoe 2J. Note that the excavated soil and sand produced by the excavation are transported as needed by a dump truck (not shown).

[0094] In this example, the work content planned in the work planning unit 11B is, in the case of the bulldozer 2G, to excavate within a specified range so that the height of the excavation bed is lowered by a specified height, and in the case of the backhoe 2J, to compact the slope within a specified range to a target shape (a specified angle (e.g., 45 degrees)).

[0095] Next, the work area set by the work area setting unit 11A when the above-mentioned three configuration tasks are performed in order will be specifically described with reference to FIGS. 8A to 8C.

[0096] Figure 8A shows a state in which the first work area A1, where the first construction work, which is the first construction work, is performed by an automatically operated bulldozer 2G, is set in an unconstructed area of ​​the planned work area A of any of the work sites 1A, 1B, 1C (work area).

[0097] When the first component work in the first working area A1 shown in Fig. 8A is completed, as shown in Fig. 8B, a new first working area A1 is set in the unfinished area of ​​the planned work area A adjacent to the completed first working area DA1 without overlapping with this area. At the same time, a second working area A2 in which the second component work, the manually operated bulldozer 2H, will be performed, is set within the area of ​​the completed first working area DA1, preferably within a range not exceeding the area of ​​the first working area DA1. As mentioned above, the second component work is excavation work near the toe of the slope, so the second working area A2 is set in a portion on the toe side of the completed first working area DA1.

[0098] In this case, the first configuration work by the automatically operated bulldozer 2G is a preceding configuration work performed before the second configuration work by the manually operated bulldozer 2H, and the second configuration work by the manually operated bulldozer 2H is a following configuration work performed after the first configuration work by the automatically operated bulldozer 2G, with the first work area A1 being the preceding work area and the second work area A2 being the following work area.

[0099] Then, when the first configuration work in the first working area A1 shown in Figure 8B is completed, a new first working area A1 is set in the unfinished area of ​​the planned work area A, adjacent to the completed first working area DA1 but not overlapping with this area, as shown in Figure 8C. Also, when the second configuration work in the second working area A2 shown in Figure 8B is completed, a new second working area A2 is set adjacent to the completed second working area DA2 but not overlapping with this area, as shown in Figure 8C. The new second working area A2 is set within the range of the completed first working area DA1 but preferably not exceeding the range of the first working area DA1. At the same time, a third working area A3, where the third configuration work, which is the third configuration work by the automatically or manually operated backhoe 2J, will be performed, is set within the range of the completed second working area DA2 but preferably not exceeding the range of the second working area DA2. As described above, the third component work is the work of compacting the slope, and therefore the third work area A3 is set in a part of the slope side (the foot side of the slope) of the second work area DA2 where the work has been completed.

[0100] In this case, the second configuration work by the manually operated bulldozer 2H is a preceding configuration work performed before the third configuration work by the automatically or manually operated backhoe 2J, and the third configuration work by the automatically or manually operated backhoe 2J is a following configuration work performed after the second configuration work by the manually operated bulldozer 2H, with the second work area A2 being the preceding work area and the third work area A3 being the following work area. In other words, the second configuration work is a following configuration work relative to the first configuration work, but a preceding configuration work relative to the third configuration work.

[0101] 8C, new work areas A1, A2, A3 are set in the same manner as described above. In this example, the third work area DA3, where the work has been completed, becomes the work completion area because the third work area DA3 is the final work area.

[0102] In this way, the height of the excavation bed in the planned work area A decreases in order from the area where all construction work has been completed, and these construction works are repeated until the height of the excavation bed reaches the construction base level.

[0103] Even in excavation work carried out using multiple construction machines 2, including autonomous construction machines 2, in order to improve construction efficiency, it is necessary to avoid the work of the construction machines 2 performing leading construction work being hindered by the construction machines 2 performing trailing construction work.

[0104] Therefore, by managing the work of each construction machine 2 involved in excavation work such as those shown in Figures 7A, 7B, and 7C using the work management method for the construction machine 2 performed by the above-mentioned work management system 100, as in the above embodiment, even if either the leading construction work or the trailing construction work is performed by an automatically driven construction machine 2, there is no risk of hindering the progress of each other's construction work, so the construction work can be performed efficiently and safety can be ensured because collisions between the construction machines 2 can be avoided.

[0105] Although the embodiments of the present invention have been described above, the above embodiments merely illustrate some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above embodiments.
