Description

[Technical field]

[0001] The present invention relates to a concrete pouring management system and a concrete pouring management method. [Background technology]

[0002] For example, Patent Document 1 discloses a technique for measuring the surface height of concrete poured into a pouring space, the technique measuring the surface height of concrete based on three-dimensional imaging information captured at the pouring site. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-60018 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the amount of concrete required to cast to a given height varies depending on the volume of the components (e.g., reinforcing bars, steel frames, etc.) placed in the casting space, even if the casting area is the same. In addition, depending on the components placed in the casting space, the surface height may not be measured or may be uneven in some places. For this reason, even if the surface height is measured using the technology of Patent Document 1 during concrete casting, the required amount of concrete cannot be accurately calculated, and the amount and timing of ordering concrete must be dependent on the experience of the manager who manages them. Note that these problems are not limited to concrete, but are common when casting a cement composition into a casting space. [Means for solving the problem]

[0005] A pouring management system that solves the above-mentioned problems is a pouring management system that manages a cement composition to be poured into a pouring space, and includes a final top position identification unit that identifies a final top position of the pouring space based on a three-dimensional model of the pouring space, a point cloud information acquisition unit that acquires point cloud information of the pouring site during pouring based on imaging information captured by an imaging device of the pouring site during pouring, a top position identification unit that identifies the top position of the cement composition being poured based on the three-dimensional model and the point cloud information, and a required amount calculation unit that calculates a required amount of cement composition required to pour up to the final top position based on the three-dimensional model, the point cloud information, the top position, and the final top position.

[0006] A pouring management method that solves the above-mentioned problems is a pouring management method that manages a cement composition to be poured into a pouring space, in which the pouring management system that manages the cement composition identifies a final top position of the pouring space based on a three-dimensional model of the pouring space, acquires point cloud information of the pouring site during pouring based on imaging information captured by an imaging device of the pouring site during pouring, identifies the top position of the cement composition during pouring based on the three-dimensional model and the point cloud information, and calculates the required amount of cement composition required to pour up to the final top position based on the three-dimensional model, the point cloud information, the top position, and the final top position.

[0007] According to the above-mentioned configuration, the manager can grasp the required amount of the cement composition required until pouring into the pouring space is completed, which makes it easy to manage the concrete.

[0008] In the above configuration, the cement composition is pressure-pumped into the pouring space from a transport vehicle that transports the cement composition to the pouring site, and the pouring management system preferably comprises a remaining amount calculation unit that calculates the remaining amount of cement composition that can be poured into the pouring space from the transport vehicle in operation, and a shortage calculation unit that calculates the shortage amount of cement composition based on the required amount and the remaining amount.

[0009] According to the above configuration, the manager can easily grasp the shortage of the cement composition, and thus the order amount and the order timing of the cement composition can be appropriately determined.

[0010] In the above configuration, it is preferable to include a completion schedule calculation unit that calculates a completion schedule time for the completion of pouring of the cement composition by the transport vehicle in operation based on the remaining amount. This allows the manager to order a new cement composition from the contractor so that the transport vehicle arrives at the pouring site at the scheduled completion time.

[0011] In the above configuration, it is preferable that the top end position specifying unit specifies the top end position using an estimation model created based on teacher information in which the three-dimensional model of the casting space and point cloud information based on image information of the casting site are used as input layers, and the top end position of the cement composition is used as an output layer. This makes it possible to specify the top end position of the cement composition being cast with high accuracy. [Brief description of the drawings]

[0013] An embodiment of a concrete pouring management system and a concrete pouring management method will be described with reference to Figs. 1 to 5. As shown in FIG. 1, at a pouring site 10, a pouring management system 11 is a system that manages a cement composition to be poured into a pouring space 12. The pouring management system 11 has a pouring management device 13. The cement composition is a fluid obtained by mixing at least cement and water. The cement composition is, for example, concrete obtained by mixing a cement mixture in which aggregates such as gravel and sand are mixed with cement and water. The cement composition may be a mortar such as Slimcrete (registered trademark), or may be one mixed with fibers (fiber-reinforced concrete material).

[0014] At the concrete pouring site 10, various pouring space forming members are installed to form the pouring space 12. The pouring space forming members are, for example, an outer frame member 14 installed so as to surround the pouring space 12, and an inner member 15 (reinforcing bars, steel frames, piping, etc.) installed inside the outer frame member 14.

[0015] Concrete to be poured into the pouring space 12 is transported by a transport vehicle 16 from a concrete factory to a pouring site based on an order from a manager. The transport vehicle 16 is a concrete pump vehicle and has a tank 17 for storing concrete. The concrete in the tank 17 is pumped to the pouring space 12 through a pressure feed path 20 composed of a pressure feed pipe 18, a hose 19, and the like. The transport vehicle 16 is provided with a tank remaining amount sensor 21 that detects the amount of concrete remaining in the tank 17. The tank remaining amount sensor 21 is configured to be able to communicate with the pouring management device 13. During communication with the pouring management device 13, the tank remaining amount sensor 21 outputs the tank remaining amount to the pouring management device 13.

[0016] At the concrete pouring site 10, an imaging device 22 is installed at a position where the concrete pouring space 12 can be imaged from above. The imaging device 22 is configured to be able to communicate with the concrete pouring management device 13. The imaging device 22 may be one or more. The imaging device 22 may be movable. The imaging device 22 is, for example, a 3D scanner such as a LIDAR (Laser Imaging Detection and Ranging). The imaging device 22 outputs imaging information obtained by imaging the concrete pouring site 10 to the concrete pouring management device 13.

[0017] (Pouring management system) The concrete pouring management system 11 will be described with reference to Figs. 2 to 5. The concrete pouring management device 13 is a portable computer. The concrete pouring management device 13 acquires various information and executes various processes based on the acquired various information, and programs and various data stored in the memory. The concrete pouring management device 13 may be configured as a circuit including one or more dedicated hardware circuits such as ASIC, one or more processors operating according to a computer program (software), or a combination thereof. The processor includes a CPU and memory such as RAM and ROM, and the memory stores program code or instructions configured to cause the CPU to execute processes. The memory, i.e., computer-readable medium, includes any available medium accessible by a general-purpose or dedicated computer.

[0018] An input device 25 and a notification device 26 are communicatively connected to the pouring management device 13. The input device 25 includes a keyboard, a pointing device, and the like. The input device 25 inputs various information, instructions to execute various processes, and the like to the concrete pouring management device 13. As various information, in-vehicle route information, pressure feed path information, and the like are input to the concrete pouring management device 13. The in-vehicle route information is information about the volume from the tank 17 to the pressure feed path 20 in the transport vehicle 16, such as the hopper volume and the piping volume inside the concrete pump vehicle. The pressure feed path information is information about the volume of the pressure feed path 20, such as the piping diameter and piping length of the pressure feed pipe 18, and the hose diameter and hose length of the hose 19.

[0019] The notification device 26 is a notification unit that notifies various information to a manager who manages concrete ordering, etc. The notification device 26 is, for example, a display device that displays various information, etc. The notification device 26 is preferably a portable terminal that can be carried so that the manager can receive notifications at the concrete pouring site 10.

[0020] A program for executing a concrete pouring management process described later is installed in the concrete pouring management device 13, whereby an estimation model 27 is input. By installing the program, the concrete pouring management device 13 stores the estimation model 27 in a part of the memory as an estimation model storage unit 28. The estimation model 27 is a model that estimates the top position of the concrete based on various information input to the concrete pouring management device 13.

[0021] The estimation model 27 is created by an estimation model creation device. The estimation model creation device creates the estimation model 27 using information obtained about various concrete pouring sites as teacher information. Specifically, the estimation model creation device creates the estimation model 27 using teacher information in which a three-dimensional model capable of reproducing the pouring space and point cloud information obtained by capturing an image of the concrete pouring site during pouring with an imaging device are used as input layers, and the top position of the concrete at the time of capturing the image is used as output layers.

[0022] The three-dimensional model is a model capable of reproducing the pouring space including the components that form the pouring space. This three-dimensional model is created based on a BIM (Building Information Modeling) model. A BIM model is a model capable of reproducing an actual building constructed in a virtual three-dimensional space, with objects such as columns, beams, walls, floors, piping, and reinforcement. Point cloud information is information that includes coordinate information based on the distance and direction from the imaging device to each position within its imaging range. The top position of the concrete is indicated in the same coordinate system as the coordinate system in the point cloud information.

[0023] We explain the estimation model 27 in detail. As shown in FIG. 3, for example, in a concrete pouring site 30, an outer frame 32 and a steel frame 33 arranged inside the outer frame 32 are installed as pouring space forming members that form a pouring space 31. In this case, when the pouring space 31 is imaged by an imaging device 34 during concrete pouring, point cloud information cannot be obtained for an unimaging part 36 of the concrete 35 that cannot be imaged by the imaging device 34 because it is covered by the steel frame 33. The estimation model 27 is a model that specifies the top end position of the concrete 35 including the unimaging part 36 and unevenness in the top end position based on a three-dimensional model that can reproduce the pouring space 31 and point cloud information obtained from the imaging information of the imaging device 34. The estimation model 27 is generated by machine learning using teacher information that combines the point cloud information, the three-dimensional model, and the top end position, with the point cloud information and the three-dimensional model as input layers and the top end position as output layers. The teacher information may be information obtained at an actual pouring site, or may be information obtained by simulation or the like.

[0024] As shown in Fig. 2, a three-dimensional model 40 of the concrete pouring space 12 is input to the concrete pouring management device 13. The concrete pouring management device 13 stores the three-dimensional model 40 in a part of its memory as a three-dimensional model storage unit 41.

[0025] The concrete pouring management device 13 has a processing unit 45 that executes various processes. The processing unit 45 has a final top position identification unit 46, a point cloud information acquisition unit 47, a top position identification unit 48, a required amount calculation unit 49, a remaining amount calculation unit 50, a scheduled completion time calculation unit 51, and a shortage amount calculation unit 52 as functional units that function by executing a program.

[0026] The final top position identifying unit 46 identifies the final top position, which is the final top position of the concrete, based on the three-dimensional model 40. The point cloud information acquisition unit 47 acquires point cloud information within the imaging range of the imaging device 22 based on the imaging information, and stores the acquired point cloud information.

[0027] The top position identifying unit 48 identifies the top position of the poured concrete based on the three-dimensional model 40, the point cloud information, and the estimated model 27. The required quantity calculation unit 49 calculates the required quantity, which is the amount of concrete required to pour concrete from the top position to the final top position, based on the three-dimensional model 40, the final top position of the concrete, and the top position of the concrete.

[0028] The remaining amount calculation unit 50 calculates the remaining amount of concrete that can be poured into the pouring space 12 from the transport vehicle 16 in operation. The estimated completion time calculation unit 51 calculates the estimated completion time for the concrete pouring by the transport vehicle 16 in operation to be completed.

[0029] The shortage calculation unit 52 calculates the shortage amount of concrete based on the required amount and the remaining amount. With reference to Figs. 4 and 5, a preparation process and a concrete pouring control process executed by the concrete pouring control device 13 in relation to the concrete pouring control method will be described.

[0030] (Preparation process) The pouring management device 13 performs preparatory processing before pouring concrete. As shown in FIG. 4, the preparation process includes a three-dimensional model acquisition process (step S101) and a final top end position specification process (step S102).

[0031] The three-dimensional model acquisition process (step S101) is a process for storing the three-dimensional model 40. The three-dimensional model acquisition process is started by performing an acquisition operation on the input device 25 while a storage medium for storing the three-dimensional model 40 is connected to the pouring management device 13. In the three-dimensional model acquisition process, the processing unit 45 of the pouring management device 13 stores the input three-dimensional model 40 in the three-dimensional model storage unit 41.

[0032] The final top position identification process (step S102) is executed when the three-dimensional model 40 is stored in the three-dimensional model storage unit 41. In this process, the final top position identification unit 46 identifies the final top position of the concrete based on the three-dimensional model 40. The final top position identification unit 46 stores final top position information indicating the identified final top position.

[0033] (Pouring management processing) The pouring management process is executed by a start operation being performed on the input device 25. When the pouring management process is started, the concrete can be poured from the transport vehicle 16 into the pouring space 12. The tank remaining amount sensor 21 and the pouring management device 13 are in a state in which they can communicate with each other, and the imaging device 22 is installed at the pouring site 10 at a position where it can capture an image of the pouring space 12.

[0034] As shown in Figure 5, the concrete pouring management process includes a point cloud information acquisition process (step S201), a top end position identification process (step S202), a required amount calculation process (step S203), a remaining amount calculation process (step S204), a planned completion time calculation process (step S205), a shortage amount calculation process (step S206), and a notification process (step S207).

[0035] The point cloud information acquisition process (step S201) is a process for acquiring point cloud information at the concrete pouring site 10. In this process, the point cloud information acquisition unit 47 acquires imaging information captured by the imaging device 22, and acquires point cloud information within the imaging range of the imaging device 22 based on the acquired imaging information. The point cloud information acquisition unit 47 stores the point cloud information.

[0036] The top end position specification process (step S202) is a process for specifying the top end position of the concrete being poured. In this process, the top end position specification unit 48 specifies the top end position of the concrete being poured based on the estimated model 27, the three-dimensional model 40, and the point cloud information, and stores top end position information indicating the specified top end position. The top end position information is information that allows the surface of the concrete being poured to be reproduced three-dimensionally, including the range that cannot be imaged by the imaging device 22.

[0037] The required amount calculation process (step S203) is a process for calculating the required amount, which is the amount of concrete required to pour concrete up to the final top position. In this process, the required amount calculation unit 49 calculates the required amount based on the three-dimensional model 40, the final top position information, and the top position information. Specifically, based on the three-dimensional model 40, the final top position, and the top position of the concrete being poured, the required amount calculation unit 49 calculates the volume of the space from the top position to the final top position minus the volume of the pouring space forming member present in that space.

[0038] The remaining amount calculation process (step S204) is a process for calculating the remaining amount, which is the amount of concrete that can be poured using the transport vehicle 16 in operation. In this process, the remaining amount calculation unit 50 calculates the remaining amount based on the tank remaining amount as well as the in-vehicle route information, the pressure feed route information, the hose information, and the like. Specifically, the remaining amount calculation unit 50 calculates the in-vehicle piping volume, which is the volume of the piping portion from the tank 17 to the pressure feed route 20, based on the in-vehicle route information. The remaining amount calculation unit 50 calculates the pressure feed route volume, which is the volume of the pressure feed route 20, based on the pressure feed route information. The remaining amount calculation unit 50 calculates the hose volume, which is the volume of the hose 19, based on the hose information. Then, the remaining amount calculation unit 50 calculates a value obtained by adding the in-vehicle piping volume and the pressure feed route volume to the tank remaining amount as the remaining amount.

[0039] The estimated completion time calculation process (step S205) is a process for calculating the time when pouring of concrete by the operating transport vehicle 16 will be completed. In this process, the estimated completion time calculation unit 51 calculates the rate at which the concrete in the tank 17 decreases based on the change in the remaining amount in the tank. Then, based on the remaining amount and the rate of decrease, the time when pouring of concrete by the operating transport vehicle 16 will be completed is calculated as the estimated completion time.

[0040] In the shortage calculation process (step S206), the shortage amount of concrete is calculated based on the required amount and the remaining amount. In this process, the shortage calculation unit 52 calculates the shortage amount by subtracting the remaining amount from the required amount.

[0041] The notification process (step S207) is a process for notifying the administrator of various information. In this process, the processing unit 45 inputs the required amount, remaining amount, estimated completion time, shortage amount, and the like obtained by the various processes described above as notification information to the notification device 26. The notification device 26 notifies the administrator of the input notification information.

[0042] The operation and effects of this embodiment will be described. (1) At the pouring site 10, the concrete manager can ascertain the required amount of concrete by checking the notification information from the notification device 26 that receives the notification from the pouring management device 13. This allows the manager to place an order for concrete with a contractor after taking into consideration the pouring plan for that day, the current time, the time required to travel from the concrete factory to the pouring site 10, and the like. As a result, concrete can be appropriately managed.

[0043] (2) In addition to the required amount, the remaining amount for the transport vehicle 16, the estimated completion time, and the amount of concrete shortage can also be grasped, so concrete can be ordered without relying on the manager's experience. As a result, the burden on the manager and the amount of returned concrete can be reduced, and concrete can be ordered taking into consideration working hours.

[0044] (3) In the concrete pouring management system 11, the top edge position of the concrete is specified by using the estimation model 27. This allows the top edge position to be specified with high accuracy, and increases the versatility of the concrete pouring management system 11.

[0045] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. The estimation model 27 is not limited to a model created based on teacher information in which the three-dimensional model of the pouring space and point cloud information based on the imaging information of the pouring site are input layers, and the top end position of the concrete is output layers. For example, the estimation model 27 may be created based on teacher information in which the three-dimensional model of the pouring space and point cloud information based on the imaging information of the pouring site are input layers, and the poured amount of concrete up to the time of imaging is output layers. According to such an estimation model 27, the poured amount of concrete can be calculated based on the three-dimensional model and the point cloud information. Then, the required amount can be calculated by subtracting the poured amount from the volume of the pouring space.

[0046] The top position identification unit 48 may determine the height position of the top position in the range that cannot be imaged by the imaging device 22 as the average height position of the top position of the concrete obtained from the point cloud information in the pouring space 12.

[0047] The concrete pouring management system 11 is not limited to a configuration that notifies the manager of various information such as the required amount, but may be configured to display various information on a display device of a computer in an office installed at the concrete pouring site. This allows the manager to grasp various information through a display device in the office. Also, the concrete pouring management system 11 may be configured to display various information on a display device of a portable terminal by the manager accessing the concrete pouring management device 13 through the portable terminal.

[0048] The concrete pouring management system 11 may be configured to notify the manager of the establishment of a predetermined condition regarding the remaining amount or the estimated completion time by a notification unit when the condition is established. In such a configuration, the notification unit may notify the manager by a sound such as an alarm sound.

[0049] The concrete pouring management system 11 may obtain point cloud information of the concrete pouring site 10 before starting concrete pouring work and calculate the required amount based on the point cloud information. This makes it possible to verify the planned concrete pouring amount calculated from the drawing. [Explanation of symbols]
