[0006] One aspect of the present invention, which solves the above-mentioned problems, includes a section determination unit that determines, based on the results of bulldozer leveling in the construction area, which sections are set to divide the construction area, which are completed sections where leveling by the bulldozer has been completed and which are incomplete sections where leveling has not been completed; and an area setting unit that sets, among the completed sections determined by the section determination unit, the area of ​​the completed section that is at a certain distance or more from the incomplete area of ​​the incomplete section as a compaction area where compaction by a roller is possible. The area setting unit sets a buffer area of ​​a predetermined width corresponding to the boundary between the completed area and the incomplete area, and sets the area of ​​the completed area determined by the area determination unit that does not overlap with the buffer area as a compaction-possible area. It is a construction management system.

[0007] One aspect of the present invention includes a section determination step in which, for sections set to divide a construction area, a completed section is determined based on the results of bulldozer leveling in the construction area, and an incomplete section is determined to be The area setting step sets a buffer area of ​​a predetermined width corresponding to the boundary between the completed area and the incomplete area, and sets the area of ​​the completed area determined by the area determination step that does not overlap with the buffer area as a compaction-possible area. This is a construction management method.

[0008] One aspect of the present invention is a program for a computer provided in a construction management system to function as a section determination unit that determines, based on the results of bulldozer leveling in the construction area, which sections are set to divide the construction area into sections, which are completed sections where leveling by a bulldozer has been completed and which are incomplete sections where leveling has not been completed; and an area setting unit that sets, among the completed sections determined by the section determination unit, the area of ​​the completed section that is a certain distance or more from the incomplete area of ​​the incomplete section as a compaction area where compaction by a roller can be performed. The program sets a buffer area of ​​a predetermined width corresponding to the boundary between the completed area and the incomplete area, and sets the area of ​​the completed area that does not overlap with the buffer area among the completed areas determined by the area determination unit as a compaction-possible area. That is the case. [Effects of the Invention]

[Figure 10] This flowchart shows an example of the processing procedure performed by the construction management server in this embodiment in relation to setting the area that can be compacted. [Modes for carrying out the invention]

[0011] Figure 1 shows an example configuration of the construction management system of this embodiment. As shown in the figure, the construction management system of this embodiment includes a bulldozer 100, a roller 200, and a construction management server 300.

[0012] The bulldozer 100 is a heavy machine that operates to level the fill at the construction site FL (an example of the construction target area). The bulldozer 100 can move at the construction site FL by autonomous driving and perform leveling (spreading). The leveling is a process of leveling the earth and sand transported by, for example, an earth and sand transport vehicle and unloaded at the construction site FL to be flat at the target height by the bulldozer 100. The technology for realizing the autonomous driving of the bulldozer 100 is not particularly limited. For example, LIDAR (Light Detection and Ranging) may be adopted as the technology for grasping the surrounding shape for autonomous driving. LIDAR is a technology that measures the distance based on the time from when pulsed laser light is irradiated to the surroundings until the reflected light is received, generates surrounding environment data indicating the shape of the surrounding environment, and estimates its own position.

[0013] The roller 200 is a heavy machine that operates to compact the area leveled by the bulldozer 100 at the construction site FL. The roller 200 may be any of compaction machines such as a vibratory roller, a combined roller, a macadam roller, etc. The roller 200 can move at the construction site FL by autonomous driving and perform compaction.

[0014] The bulldozer 100 and the roller 200 are communicably connected to the construction management server 300. Also, the bulldozer 100 and the roller 200 are mutually communicable.

[0015] The bulldozer 100 measures the height of the ground at the construction site FL while performing leveling at the construction site FL, and transmits the information on the measured height to the construction management server 300. Based on the height received from the bulldozer 100, the construction management server 300 identifies an area (compaction - possible area) at the construction site FL where leveling by the bulldozer is completed and compaction by the roller 200 can be performed. The construction management server 300 notifies the roller 200 of the identified compaction - possible area. The roller 200 can perform leveling of the notified compaction area.

[0016] When causing the bulldozer 100 to perform leveling by autonomous driving and performing leveling in a lump for the entire area of the construction site FL, there may be difficulties in terms of management and safety assurance. Therefore, the construction management system of this embodiment divides the construction site FL into section units, and the bulldozer 100 performs leveling in section units. The construction management server 300 identifies the compaction - possible area in section units based on the result of determining whether leveling in section units is completed. The roller 200 is made to perform compaction of the compaction - possible area in section units. Also, by notifying the bulldozer 100 of the identified compaction - possible area, the bulldozer 100 can perform autonomous driving so as not to enter the identified compaction - possible area. Thereby, it is possible to prevent the bulldozer 100 from approaching the periphery of the roller 200 that performs compaction. In this way, in the construction management system of this embodiment, the autonomously - driven bulldozer 100 and the roller 200 can be operated in cooperation.

[0017] FIG. 2 shows a functional configuration example of the bulldozer 100. The bulldozer 100 includes a communication unit 101, a sensor unit 102, a positioning unit 103, a vehicle mechanism unit 104, a blade mechanism unit 105, a control unit 106, and a storage unit 107.

[0018] The communication unit 101 communicates with the construction management server 300 via wireless communication. The sensor unit 102 is a part that comprehensively represents the various sensors provided by the bulldozer 100. In this embodiment, the sensor unit 102 includes a sensor that emits laser light to generate ambient environment data and estimate its own position when performing autonomous operation using LIDAR, and receives the reflected laser light. The sensor unit 102 in this embodiment also includes a sensor that measures the height of the construction site floor level (FL). In addition, ambient environment data generated by LIDAR may be used to measure the height of the construction site FL. The positioning unit 103 is equipped with a device that supports, for example, GPS (Global Positioning System), and measures its own position.

[0019] The vehicle mechanism 104 is the mechanism corresponding to the vehicle in the bulldozer 100. By driving the vehicle mechanism 104 under the control of the autonomous driving control unit 161, the bulldozer 100 can move under autonomous driving conditions. The blade mechanism 105 is a mechanism that can move the blade. By driving the blade mechanism 105 under the control of the autonomous driving control unit 161, the bulldozer 100 can move the blade appropriately under autonomous driving conditions.

[0020] The control unit 106 controls the bulldozer 100. The functions of the control unit 106 are realized by the execution of a program by the CPU (Central Processing Unit) provided in the bulldozer 100. The control unit 106 includes an autonomous driving control unit 161 and a height measuring unit 162. The autonomous driving control unit 161 performs control related to the autonomous operation of the bulldozer 100. The autonomous driving control unit 161 estimates its own position at the construction site FL based on the output of sensors such as a camera and laser scanner in the sensor unit 102. The autonomous driving control unit 161 also controls the vehicle mechanism unit 104 so that the bulldozer 100 moves based on the self-position estimation result. Furthermore, the autonomous driving control unit 161 controls the vehicle mechanism unit 104 and the blade mechanism unit 105 so that leveling is performed at the appropriate position. The height measuring unit 162 measures the height of the ground level (FL) at the construction site using the output of a predetermined sensor provided in the sensor unit 102. The memory unit 107 stores predetermined information related to the bulldozer 100.

[0021] Figure 3 shows an example of the functional configuration of the roller 200. The roller 200 comprises a communication unit 201, a sensor unit 202, a positioning unit 203, a vehicle mechanism unit 204, a roller mechanism unit 205, a control unit 206, and a storage unit 207.

[0022] The communications unit 201 communicates with the construction management server 300 via wireless communication. The sensor unit 202 is a part that encompasses various sensors provided by the roller 200. The sensor unit 202 includes sensors for generating ambient environment data and estimating the self-position in response to autonomous driving. The positioning unit 203 is equipped with a device such as GPS and measures its own position.

[0023] The vehicle mechanism 204 is the mechanism corresponding to the vehicle in the roller 200. By driving the vehicle mechanism 204 under the control of the autonomous driving control unit 261, the roller 200 can move under autonomous driving conditions. The roller mechanism 205 is a mechanism related to rollers.

[0024] The control unit 206 controls the roller 200. The functions of the control unit 206 are realized by the execution of a program by the CPU provided in the roller 200. The control unit 206 includes an autonomous driving control unit 261. The autonomous driving control unit 261 performs control related to the autonomous operation of the roller 200. The autonomous driving control unit 261 estimates its own position at the construction site FL based on the output of sensors such as cameras and radars in the sensor unit 202, and the autonomous driving control unit 261 controls the vehicle mechanism unit 204 so that the roller 200 moves according to the compaction process based on the self-position estimation result. The memory unit 207 stores predetermined information related to the roller 200.

[0025] Figure 4 shows an example of the functional configuration of the construction management server 300. The construction management server 300 comprises a communication unit 301, a control unit 302, and a storage unit 303. The functions of the construction management server 300 shown in the figure are realized by the CPU of the construction management server 300 executing programs. The communication unit 301 communicates with the bulldozer 100 and the roller 200 via wireless communication.

[0026] The control unit 302 performs various controls on the construction management server 300. The control unit 302 includes an information acquisition unit 321, a partition determination unit 322, a region setting unit 323, and an information transmission unit 324. The information acquisition unit 321 acquires information transmitted from the bulldozer 100 to the construction management server 300. The information acquired by the information acquisition unit 321 from the bulldozer 100 includes measured height information (height information). The information acquisition unit 321 may also be capable of acquiring information transmitted from the roller 200 to the construction management server 300. The section determination unit 322 determines, based on the height information acquired by the information acquisition unit 321, which sections have been set for the construction site floor level (FL), whether they are completed sections where leveling by the bulldozer 100 has been completed or incomplete sections where leveling has not been completed. The area setting unit 323 sets a compaction-possible area where compaction by the roller 200 is possible. The compaction-possible area is a set of sections that have been determined by the section determination unit 322 to be compaction-possible from among the completed sections. When determining whether or not a section can be compacted as a completed section, the area setting unit 323 determines whether or not the condition is met that the section is located at a certain distance or more from the boundary between the completed area (formed by the completed sections) and the incomplete area (formed by the incomplete sections) at the construction site FL. The information transmission unit 324 transmits predetermined information to the bulldozer 100 and the roller 200. The information transmitted by the information transmission unit 324 includes information indicating the compaction area set by the area setting unit 323.

[0027] The storage unit 303 stores various types of information corresponding to the construction management server 300. The storage unit 303 includes a construction status data storage unit 331. The construction status data storage unit 331 stores construction status data. The construction status data is data that shows the progress of leveling by the bulldozer 100 as the construction status at the construction site FL. Specifically, the construction status data may be data that indicates whether each section on a map, which divides the construction site FL into sections, is a completed section or an incomplete section as determined by the section determination unit 322.

[0028] Referring to Figures 5 to 8, an example of the procedure for setting the compaction-enabled area using the construction management server 300 will be explained. In Figure 5, the construction area AR1 corresponds to the area of ​​the construction site FL as viewed from a plane. The construction area AR1 is divided by partitions Di. In the diagram, partitions Di are set relative to the construction area AR1 in a rectangular mesh pattern. Note that the size (dimensions) of partitions Di do not have to be uniform. Also, the shape of partitions Di does not have to be a rectangle. Furthermore, as shown in the diagram, the partition-corresponding construction area AR20 is set as a region formed by the collection of partitions Di set relative to the construction area AR1. As shown in the figure, the map in the construction status data is created by setting a partition-corresponding construction area AR20 for the construction area AR1. Therefore, the map in the construction data area shows the construction area AR1 divided by partition Di. Furthermore, the construction area AR1 in the same figure shows the state during construction. In this figure, the progress of construction in construction area AR1 is shown by the completed area AR11, where leveling by bulldozer 100 has been completed, and the incomplete area AR12, where leveling has not yet been completed.

[0029] The height measuring unit 162 of the bulldozer 100, which is leveling the ground at the construction site FL, measures the height of the ground at the construction site FL at a predetermined timing. In this case, the height measuring unit 162 may, for example, measure the height of the site portion corresponding to the plot unit that has been targeted for leveling at the construction site FL. Alternatively, the height measuring unit 162 may measure the height relative to a reference plane set at the construction site FL. This allows the height measuring unit 162 to obtain information on the height distribution of the site portion being measured.

[0030] The height measurement unit 162 transmits height information, which shows the height distribution measured for the site area being measured, to the construction management server 300. The height information also includes location range information, which indicates the location range corresponding to the measured site area.

[0031] In the construction management server 300, the information acquisition unit 321 acquires height information transmitted from the bulldozer 100. The section determination unit 322 of the construction management server 300 determines whether leveling has been completed for a section Di that falls within the position range indicated by the position range information included in the height information acquired by the information acquisition unit 321, using the height distribution information indicated by the height information. At this time, the section determination unit 322 calculates the height difference ΔH between the measured height and the target height for each measurement point in the height distribution indicated by the height information. The section determination unit 322 determines whether the calculated elevation difference ΔH is less than a predetermined allowable range Emx. If the elevation difference ΔH of all measurement points in the section Di to be determined is less than the allowable range Emx, the section Di to be determined is determined to be a completed section where leveling has been completed. In addition, the section determination unit 322 determines that any section Di that has not been determined to be a completed section so far is an incomplete section where leveling has not been completed. The section determination unit 322 then divides each section Di set in the section-corresponding construction area AR20 at the construction site FL into completed sections and incomplete sections.

[0032] Figure 6 shows the result of the section determination unit 322 dividing the section-corresponding construction area AR20 into completed and incomplete sections, targeting construction area AR1, which has both a completed area AR11 and an incomplete area AR12 as shown in Figure 5. As shown in Figure 6, among the sections Di included in the section-corresponding construction area AR20, sections Di in which the entire portion included as construction area AR11 is actually completed area AR11 are classified as completed sections D1. On the other hand, among the sections Di included in the section-corresponding construction area AR20, sections Di in which at least a portion is actually incomplete area AR12 are classified as incomplete sections D2.

[0033] In this embodiment, the process starts from a certain section Di in the construction area AR1, and the area where leveling is completed is expanded by further leveling the section Di adjacent to the section Di where leveling has been completed. For this reason, the section-corresponding construction area AR20 in Figure 6 is divided into a completed section area AR21 consisting of six completed sections D1, and an incomplete section area AR22 consisting of incomplete sections D2 that are not included in the completed section area AR21. The section determination unit 322 may also perform this division between the completed section area AR21 and the incomplete section area AR22 based on the division result of the completed section D1 and the incomplete section D2.

[0034] Next, the area setting unit 323 in the construction management server 300 performs the following process to identify areas that can be compacted based on the division results of completed area D1 and incomplete area D2 in Figure 6. First, the area setting unit 323 sets a buffer area corresponding to the boundary between the completed area AR21 and the incomplete area AR22, according to the division result of the completed area D1 and the incomplete area D2 in Figure 6. Figure 7 shows an example of setting a buffer area ARm for the boundary between the completed area AR21 and the incomplete area AR22 shown in Figure 6. The buffer area ARm shown in the figure includes the boundary between the completed area AR21 and the incomplete area AR22 and is a strip-shaped area with a predetermined width W.

[0035] Among the completed sections D1, any section D1 that overlaps with the buffer area ARm will be adjacent to an incomplete section D2. The fact that a completed section D1 is adjacent to an incomplete section D2 means that there is an area in the vicinity of that completed section D1 where leveling has not yet been completed. Thus, if the roller 200 compacts the completed section D1 while there are areas nearby that have not yet been leveled, there is a possibility that compaction will extend to areas where leveling is incomplete and compaction should not be performed. For this reason, it is preferable to exclude the completed section D1 adjacent to the incomplete section D2 from the list of candidates for sections that can be compacted (sections that can be compacted).

[0036] Therefore, as shown in Figure 8, the area setting unit 323 sets the completed sections D1 included in the completed section area AR21 that do not overlap with the buffer area ARm as compaction-ready sections D11. The area setting unit 323 sets the set compaction-ready sections D11 as the compaction-ready area. In the example in Figure 7, since one compaction-ready section D11 is set, the area setting unit 323 sets the compaction-ready area using this one compaction-ready section D11.

[0037] The information transmission unit 324 of the construction management server 300 transmits compaction-possible area information relating to the set compaction-possible area to the bulldozer 100 and roller 200 at the construction site FL. The compaction-possible area information includes information indicating the location range of the set compaction-possible area. If the bulldozer 100 and roller 200 are configured to store a map of the construction site FL divided by section Di, the compaction-possible area information may also include information indicating the section Di that forms the set compaction-possible area. The roller 200 operates to compact the area designated as a compaction-possible area by the received compaction-possible area information. The roller 200 is also configured to transmit its operating status to the bulldozer 100. This allows the bulldozer 100 to move in a way that avoids approaching the compaction-possible area when the roller 200 is compacting it, thereby enhancing safety.

[0038] Referring to the flowchart in Figure 9, an example of the processing procedure performed by the bulldozer 100 in relation to measuring the height of the construction site floor level (FL) will be described. Step S100: In the bulldozer 100, the height measuring unit 162 is waiting for a height measurement trigger to occur. The height measurement trigger is a trigger that instructs the measurement of the height of the construction site's floor level (FL). The height measurement trigger may be generated, for example, when the autonomous operation control unit 161 of the bulldozer 100 determines that it has completed movement for leveling in a certain target area Di, or when a certain amount of time has elapsed since the bulldozer 100 was started for leveling. Step S102: In response to the occurrence of a height measurement trigger, the height measurement unit 162 measures the height of the ground at the construction site FL. Step S104: The height measuring unit 162 transmits the height measured in step S102 and height information indicating the position range in which the height was measured to the construction management server 300.

[0039] Referring to the flowchart in Figure 10, an example of the processing procedure performed by the construction management server 300 in relation to setting the compaction area will be explained. Step S200: In the construction management server 300, the information acquisition unit 321 acquires the height information transmitted in step S104 of Figure 9.

[0040] Step S202: The section determination unit 322 uses the height information obtained in step S200 to divide the section Di set for the construction site FL into completed section D1 and incomplete section D2 on the construction status data map stored in the construction status data storage unit 331, as explained with reference to Figure 6. Based on the results of this division, the section determination unit 322 also divides the section-corresponding construction area AR20 set on the map into completed section area AR21 and incomplete section area AR22. In this way, by executing the process of step S202 using the construction status data map, the progress of leveling is reflected in the construction status data as part of the construction status.

[0041] Step S204: The area setting unit 323 determines whether a new completed area D1 has been obtained as a result of the division of completed area D1 and incomplete area D2 in step S02. If it is determined that a new completed area D1 has not been obtained, the process shown in the figure is terminated.

[0042] Step S206: If it is determined in step S204 that a new completed section D1 has been obtained, the area setting unit 323 sets the buffer area ARm as described with reference to Figure 7. Step S208: The area setting unit 323 sets compaction-possible sections D11 as described with reference to Figure 8, and sets a compaction-possible area by the collection of the set compaction-possible sections D11. Step S210: The information transmission unit 324 transmits compaction-possible area information related to the compaction-possible area set in step S208 to the bulldozer 100 and the roller 200.

[0043] The following describes some modified examples of this embodiment. In the above embodiment, the bulldozer 100 measures the height of the ground at the construction site FL, and the construction management server 300, based on the measured height, performs the steps from dividing the area into completed section D1 and incomplete section D2 to setting the area that can be compacted, as shown in Figure 10. However, the bulldozer 100 may perform the processing up to a predetermined stage in steps S202 to S208 in Figure 10, and the construction management server 300 may perform the processing of the remaining stages.

[0044] In the above embodiment, we took the example of a construction site floor level (FL) where soil and sand are spread and leveled. However, the construction management system of this embodiment can also be applied to construction sites where concrete is spread and leveled using bulldozers, such as dams.

[0045] In the above embodiment, completed sections D1 that overlap with the buffer zone were uniformly excluded from the candidates for compaction-ready sections D11. However, among the completed sections D1 that overlap with the buffer zone, those completed sections D1 that have a certain percentage or more of uncompleted sections D2 adjacent to them that satisfy the condition of having completed leveling the ground may be set as compaction-ready sections D11.

[0046] In the above embodiment, an example was given in which the bulldozer 100 and the roller 200 are each configured to operate autonomously. However, at least one of the bulldozer 100 and the roller 200 may be operated (controlled) by a person. For example, if the roller 200 is operated by a person, the roller 200 may display the position range indicated by the compaction-possible area information received from the construction management server 300 on a map of the construction site FL. The operator of the roller 200 confirms the displayed position range and operates the roller 200 to perform compaction.

[0047] Furthermore, the programs for realizing the functions of the bulldozer 100, roller 200, and construction management server 300 described above may be recorded on a computer-readable recording medium, and the programs recorded on this recording medium may be loaded into a computer system and executed to perform the processing of the bulldozer 100, roller 200, and construction management server 300 described above. Here, "loading the programs recorded on the recording medium into a computer system and executing them" includes installing the programs into the computer system. Here, "computer system" includes hardware such as the OS and peripheral devices. Also, "computer system" may include multiple computer devices connected via a network including communication lines. The recording medium also includes internal or external recording media that are accessible from the distribution server for distributing the programs. [Explanation of symbols]
