In addition, the same code | symbol is attached | subjected about the element which is the same or it corresponds in each figure, and the overlapping description is abbreviate | omitted.

  The present embodiment is applied to a construction system for a construction machine that performs embankment work (building work for embedding embankment material (soil) to create a flat ground surface). The construction machine construction system according to the present embodiment is operated by a single operator with a dump trap (transport machine), a bulldozer (laying machine) and a vibrating roller (rolling machine), which are construction machines having an automatic operation function. The construction management department.

  The construction machine construction system 1 will be described with reference to FIGS. As shown in FIG. 1, in the construction machine construction system 1, construction information necessary for each work is transmitted from the construction management unit 2 to the dump truck 3, the bulldozer 4, and the vibration roller 5, and dumped according to the construction information. The truck 3, the bulldozer 4 and the vibrating roller 5 perform each operation by unattended automatic operation. In the construction machine construction system 1, work completion information is transmitted from the dump truck 3, the bulldozer 4, and the vibration roller 5 to the construction management unit 2 every time each work is completed, and the construction management unit 2 performs the work completion information. Set the construction information for the next work using. The number of dump trucks 3, bulldozers 4 and vibration rollers 5 is one or more, and is appropriately determined according to the size of the construction range of the embankment work. In particular, the work with the vibrating roller 5 requires more work time than each work with the dump truck 3 and the bulldozer 4, so that the number of the vibrating rollers 5 is larger than the number of the dump truck 3 and the bulldozer 4 to perform the embankment work. Time can be shortened.

  FIG. 2 shows an example of a construction site. In the construction site, a loading area A in which soil is loaded and a construction area B in which construction is performed are connected by a transportation road C. The transportation road C is a private road. In the construction area B, a creation range D in which embankment work is performed is set. The creation range D is, for example, a rectangular shape shown in FIG. In the construction area B, the construction management unit 2 is provided at a place other than the creation range D. The construction management unit 2 is arranged at a position where the operator of the construction management unit 2 can overlook the entire creation range D.

  FIG. 3 shows the flow of each work when performing a banking work. First, when the dump truck 3 is loaded with soil at a predetermined position in the loading area A, the dump truck 3 transports the soil to a predetermined position within the construction range D of the construction area B and unloads it (transportation work). The construction position information necessary for the transportation work is a loading position in the loading area A and an unloading position in the creation range D. Furthermore, as the construction position information, a via position may be provided between the loading position and the unloading position. The work completion position information of the transportation work is an unloading completion position that is an actual unloading position. The unloading completion position is the unloading position or a position near the unloading position. The dump truck 3 normally transports the maximum amount of soil that can be transported. However, the dump truck 3 may carry a predetermined amount of soil less than the maximum amount of soil. In this case, the construction management unit 2 sets the amount of soil to be transported as construction condition information necessary for the transportation work.

  Next, the bulldozer 4 spreads the unloaded soil to a predetermined thickness starting from the unloading completion position (laying operation). The construction position information necessary for the leveling work is the unloading completion position and the section range or the creation range D partitioned within the creation range D. The work completion position information of the spread work is a spread completion range which is a range where the spread is actually completed. However, in the case where it is not possible to spread all of the section range or the creation range D that is the planned range of the spreading work, a spread unfinished range that is a range where the spread has not been completed is formed. The leveling thickness of the leveling work may be determined in advance or may be set by the construction management unit 2 as construction condition information necessary for the leveling work.

  Next, the oscillating roller 5 performs a compacting operation to compact the soil by compacting the soil spread in the leveling completion range. As for the rolling work, the work may be started when the entire section range (or the creation range D) is completed, or the partial work of the partial area (or the creation range D) is performed. When is completed, the work may be started from a part of the area. The construction position information necessary for the rolling work is the leveling completion range. The work completion position information of the rolling work is a rolling completion range that is a range where the rolling is actually completed. The completion condition of the rolling work is whether the number of times of rolling actually reaches the number of times of rolling or a predetermined condition indicating the degree of compaction. This predetermined condition is, for example, whether the vibration acceleration of the roller 5a vibrated by the vibration roller 5 is below a predetermined acceleration or the vibration amplitude of the roller 5a is below a predetermined value. The number of rolling operations or a predetermined condition (such as an acceleration threshold value) of the rolling operation may be determined in advance or may be set by the construction management unit 2 as construction condition information necessary for the rolling operation.

  In the example shown in FIG. 4A, loading positions PA1 to PA3 are set in the loading area A. In the example shown in FIG. 4B, unloading positions PD1 to PD6 are set in the creation range D. In the case of this example, ((area of creation range D × soil amount per unit area required for embankment work) / maximum soil amount of one transport operation by dump truck 3) It is judged that the amount of soil required for carrying work is necessary. Then, the creation range D is divided into six equal parts, and the unloading positions PD1 to PD6 are distributed to the center positions of the respective division ranges AD1 to AD6. Each of the division ranges AD1 to AD6 is a planned range for the leveling work. In FIG.4 (c) and FIG.4 (d), in the leveling operation | work, the location where the leveling was completed is hatched. In the case of the example shown in FIG. 4C, all the division ranges AD <b> 1 to AD <b> 6 have been completed, and the spread completion range. On the other hand, in the case of the example shown in FIG. 4D, part of the division ranges AD5 and AD6 is not yet completed, and the leveling is incomplete ranges AD5 'and AD6'. The spread unfinished ranges AD5 'and AD6' are, for example, valley shapes that are depressed more than other locations in the creation range D, and are locations where the spread thickness has not been reached. For the spread unfinished ranges AD5 'and AD6', an unloading position PD7 is newly set, and additional transport work, spread work, and rolling work are performed.

  With reference to FIG. 5, the flow of the construction method of the banking construction by the construction machine construction system 1 is demonstrated. FIG. 5 is a diagram showing a flow of a construction method by the construction machine construction system 1. When the creation range D of the banking work is determined, the construction management unit 2 divides the creation range D by an operation by the operator or automatic setting by the computer 23, and sets a plurality of division ranges. The following operation is repeatedly performed on the plurality of partition ranges. However, when the creation range D is small and the embankment can be performed with the amount of soil of one transport operation, the creation range D is not partitioned. In this case, the following operation is performed only once for the creation range D. During the embankment work, the operator monitors the status of each work of the dump truck 3, the bulldozer 4, and the vibration roller 5 performed within the creation range D.

  First, the construction management unit 2 sets a loading position in the loading area A by an operation by an operator or automatic setting by the computer 23, and within the section range of the creation range D (however, it may be in the creation range D). An unloading position is set (S20). And the construction management part 2 transmits a conveyance work start instruction | command, a loading position, and an unloading position to the dump truck 3 as construction information of conveyance work (S21: conveyance construction information transmission process).

  The dump truck 3 receives the transportation work start command, the loading position, and the unloading position (S30: transportation construction information receiving step). Then, the dump truck 3 moves to the loading position by automatic operation. When the soil is loaded at the loading position, the dump truck 3 moves to the unloading position by automatic operation and lowers the soil at the unloading position (S31: automatic transportation operation process). When the transportation work is completed, the dump truck 3 transmits a transportation work completion notification, an unloading completion position, and a soil volume to the construction management unit 2 as work completion information of the transportation work (S32: transportation work completion information transmission step). The dump truck 3 may not transmit the unloading completion position to the construction management unit 2 in some cases.

  The construction management unit 2 receives the transportation work completion notification, the unloading completion position, and the amount of soil (S22: transportation work completion information receiving step). The construction management unit 2 sets the unloading completion position as the leveling start position of the bulldozer 4 by an operation by the operator or automatic setting by the computer 23 (S23). Then, the construction management unit 2 sets the leveling work start command, the section range within the creation range D (but may be the creation range D), and the unloading completion position to the bulldozer 4 as construction information of the leveling work. Transmit (S24: flooring information transmission step). The construction management unit 2 may transmit only the leveling work start command and the unloading completion position to the bulldozer 4 as the leveling work construction information. Further, when the dump truck 3 does not transmit the unloading completion position, the construction management unit 2 transmits only the leveling work start command and the section range within the creation range D to the bulldozer 4 as the leveling work construction information. . In this case, the bulldozer 4 may detect the position where the dump truck 3 unloads the soil by the embankment material detection device 43. Further, the construction management unit 2 may transmit only a spread work start command to the bulldozer 4 as the spread work construction information.

  The bulldozer 4 receives the spread work start command, the section range, and the unloading completion position (S40: spread work information receiving step). Then, the bulldozer 4 spreads the soil that has been lowered to the unloading completion position so as to be spread and thickened in the section range by automatic operation (S41: automatic spread operation operation step). When the spreading work is completed, the bulldozer 4 transmits the spread work completion notification and the spread completion range (corresponding to the section range) to the construction management unit 2 as work completion information of the spread work (S42: Leveling work completion information transmission process). However, if the entire area of the section cannot be spread and spread to the thickness (if the spread work has not been completed), the bulldozer 4 will notify the spread work incomplete and the spread complete range. The spread unfinished range is transmitted to the construction management unit 2 (S42: spread work completion information transmission step). In addition, when the construction management unit 2 transmits only the leveling work start command and the unloading completion position as the leveling work construction information, the bulldozer 4 automatically operates the soil that has been lowered to the unloading completion position. And spread a predetermined range within the creation range D to a thickness. Further, when the construction management unit 2 transmits only the leveling work start command and the section range within the creation range D as the leveling work construction information, the bulldozer 4 uses the embankment material detection device 43 to place the dump truck 3 into the soil. The unloading position is detected, and it is spread in the area of the section by automatic operation. Further, even when the construction management unit 2 transmits only the leveling work start command as the leveling work construction information, the bulldozer 4 autonomously unloads the soil from the dump truck 3 by the embankment material detection device 43. The position can be detected, and a predetermined range within the creation range D can be spread by automatic operation and spread to a thickness.

  The construction management unit 2 receives the leveling work completion notification and the leveling completion range (S25: leveling work completion information receiving step). Alternatively, the construction management unit 2 receives a spread work incomplete notification and a spread complete range and a spread complete range (S25: spread work completion information receiving step). The construction management unit 2 sets the spread completion range as the rolling range of the vibration roller 5 by an operation by the operator or automatic setting by the computer 23 (S26). And the construction management part 2 transmits a rolling work start command and a spread completion range to the vibrating roller 5 as construction information of the rolling work (S27: rolling work information transmission process).

  The vibration roller 5 receives the rolling work start command and the spread completion range (S50: rolling pressure construction information receiving process). Then, the vibration roller 5 is spread in an automatic operation, and the completion range is pressed and compacted (S51: automatic rolling operation operation process). When the rolling work is completed, the vibrating roller 5 transmits a rolling work completion notification and a rolling pressure completion range to the construction management unit 2 as work completion information of the rolling work (S52).

  The construction management unit 2 receives the rolling work completion notification and the rolling compaction completion range (S28). The construction management unit 2 determines that the banking work in the creation range D is completed when all the work is completed for all the division ranges in the creation range D. However, when there is a spread incomplete range, the above operation is performed on the spread incomplete range. In this case, the construction management unit 2 determines that the banking work in the creation range D is completed when all the work is completed for the spread and incomplete range.

  Each transmission of S21, S24, and S27 (that is, the start timing of each work) may be performed at a timing according to an operation by an operator who monitors the work status or automated timing by the computer 23. It may be done at. In particular, for the rolling work, the work may be started after the completion of the spread of the entire section range, or the work may be started when the spread of a part of the section range is finished. . When the rolling operation is started when the spread of a part of the area is completed, the bulldozer 4 transmits S42 every time the spread of the predetermined area within the division range is completed during the spread operation. To do. In this transmission, the spread partial end notice and the range of the spread finished area are transmitted. For each transmission, the construction management unit 2 performs operations S25, S26, and S27, and the vibration roller 5 performs operations S50, S51, and S52.

  The construction machine construction system 1 transmits construction start information and construction position information from the construction management unit 2 to a plurality of construction machines 3, 4 and 5, respectively. Each of them is operated automatically by using As a result, the construction machine construction system 1 can automatically operate a plurality of construction machines 3, 4, and 5 under the control of the construction management unit 2, and highly efficient construction by a single operator (small number of people). It becomes possible.

  The construction machine construction system 1 sets the construction position information of the next work from the work completion position information of the previous work, thereby causing the construction machine to perform the next work according to the position where the previous work is completed. A plurality of construction machines 3, 4 and 5 can be operated sequentially in the same construction range D.

  In addition, due to the decrease in the number of construction workers and aging, the number of skilled workers in construction work is expected to decrease dramatically. Therefore, in order to efficiently perform a large number of construction work with a small number of people with high quality, it is indispensable to increase the mechanization rate at the construction site and promote automation. Therefore, by applying a system similar to the construction machine construction system 1 to various construction sites and using skilled workers as operators, it is possible to increase the mechanization rate and promote automation at the construction site by a small number of people. . Particularly, since appropriate construction information can be transmitted from the construction management unit 2 to each construction machine in accordance with the operation of the operator, the high skill of the operator can be reflected in the construction work of each construction machine.

  As mentioned above, although embodiment of this invention was described, it is implemented in various forms, without being limited to the said embodiment.

  For example, in the above embodiment, the dump truck (transport machine), bulldozer (laying machine), and vibration roller (rolling machine) are unattended automatic operation, and the dump truck, bulldozer and vibration roller are managed by the construction management unit. However, the dump truck and the bulldozer may be automatically operated unattended, the vibration roller may be manually operated by a person, and only the dump truck and the bulldozer may be managed by the construction management unit. In this case, the dump truck and the bulldozer can be operated automatically by the construction management unit. In particular, in this case, since the vibrating roller is manned, it is possible to sequentially compact the places where the leveling by the bulldozer has been completed. Further, the bulldozer and the vibration roller may be unattended automatic operation, the dump truck may be manually operated by a person, and the bulldozer and the vibration roller may be managed by the construction management unit. Also in this case, the construction management unit can operate the bulldozer and the vibrating roller in an automatic operation. In this case, in particular, since the dump truck is manned, it is possible to travel on public roads.

  Moreover, in the said embodiment, when the amount of soil by several times of carrying work was required, the inside of the creation range was divided and each operation | work was performed for every division range, However, It is applicable also when not dividing the creation range. If the construction area is not partitioned, the unloading position is set appropriately in the unworked area within the construction area, and a predetermined range is spread according to the amount of soil unloaded at the unloading position. Compact inside. This series of operations is repeated until the entire creation range is completed. In this case as well, the construction management unit sequentially operates the dump truck, the bulldozer, and the vibration roller by adding the operation start information of each work to the dump truck, the bulldozer, and the vibration roller, and sequentially transmitting the construction position information. it can. Since the division range is not set within the creation range, there is no case where the spread is not completed in the spread work as in the above embodiment.

  Moreover, although it applied to the embankment construction using soil as a material in the said embodiment, it is applicable also to the construction using other materials, such as concrete. In the above embodiment, a dump truck is used as the transporting machine, but other transporting machines such as a truck mixer can also be applied. In the above embodiment, the bulldozer is used as the spreader, but other spreaders such as a backhoe can be applied. In the above-described embodiment, the vibration roller is used as the compaction machine, but other compaction machines such as a load roller and a tire roller are also applicable.

  Moreover, although it was set as the structure which wirelessly communicates between a construction management part and each construction machine in the said embodiment, it is good also as a structure which wirelessly communicates between construction machines and transmits / receives information between construction machines. For example, by sharing current position information between construction machines, each construction machine working in the same construction range D can move smoothly while avoiding other construction machines.

  As described above, since the rolling operation requires time, the same rolling range may be rolled by a plurality of vibrating rollers 5. In this case, the number of times each vibrating roller 5 has rolled is accumulated, and the rolling operation is terminated when the accumulated number reaches the number of rolling times. Therefore, each time each vibration roller 5 finishes one rolling, the information is transmitted to the construction management unit 2, and the number of times each vibration roller 5 is rolled by the construction management unit 2 is accumulated and accumulated. It is determined whether the number of times has reached the number of times of rolling. In addition, when wireless communication is possible between the plurality of vibration rollers 5, the number of times of rolling between the vibration rollers 5 is shared, and the number of times each vibration roller 5 is rolled in the vibration roller 5 serving as a master unit is integrated, It is determined whether the accumulated number has reached the number of times of rolling. Alternatively, the rolling pressure range may be divided into a plurality of regions, and the divided regions may be respectively rolled by the plurality of vibration rollers 5. In this case, the construction management unit 2 transmits each area obtained by dividing the rolling pressure range and the rolling work start command to each vibration roller 5. Thus, by performing the rolling operation with the plurality of vibrating rollers 5, the time required for the entire rolling operation can be shortened.
