[0016] Below, based on the attached drawings, we will explain the concrete pouring management system and concrete pouring management method related to this embodiment.

[0017] [Overall configuration] As shown in FIG. 1, the concrete pouring management system 1 according to this embodiment includes a filling information acquisition unit 10, a compaction information acquisition unit 20, a data management device 30, and a user terminal device 40. The filling information acquisition unit 10, the compaction information acquisition unit 20, and the user terminal device 40 are installed at a construction site where fresh concrete is poured into a formwork to construct a desired concrete structure. The data management device 30 is a server device installed in, for example, a management company's cloud computing system or data management center, and is installed in a remote location away from the construction site. The filling information acquisition unit 10, the compaction information acquisition unit 20, and the user terminal device 40 are connected to the data management device 30 via a network 50 such as the Internet so that they can communicate with each other.

[0018] The filling information acquisition unit 10 includes a plurality of filling detection sensors 11, a filling state recognition processing unit 12, a filling display unit 13, a filling position information acquisition unit 14, and a first communication unit 15.

[0019] The filling detection sensor 11 is installed at a predetermined location within the formwork into which concrete is to be filled. The filling detection sensor 11 is installed, for example, at locations within the formwork where imperfect concrete filling is likely to occur (corners of the structure, areas with dense reinforcement, around sheathed pipes into which PC steel wires are inserted, etc.). The filling detection sensor 11 is connected to the filling status recognition processing unit 12 via a cable and transmits a detection signal to the filling status recognition processing unit 12 at a predetermined interval. The detection method of the filling detection sensor 11 is not particularly limited, and for example, a frequency characteristic detection method using a vibration device or a capacitance detection method using electrode wires can be applied. These detection methods themselves are well known, so they will be briefly described below.

[0020] The frequency characteristic detection method uses a sine wave excitation signal to vibrate a sensor element that converts an electrical signal into mechanical vibration, and varies the frequency within a desired range. The frequency characteristic detection method can detect a filler such as concrete by detecting a change in the frequency characteristics of the sensor element when the filler contacts the sensor element. The capacitance detection method uses a pair of electrode wires that extend parallel to each other. The capacitance detection method can detect a filler such as concrete by detecting a change in capacitance between the pair of electrode wires when the filler contacts the electrode wires, depending on the dielectric constant of the filler.

[0021] The filling status recognition processing unit 12 is a so-called microcomputer equipped with a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), etc. The filling status recognition processing unit 12 executes a filling status recognition process to recognize whether concrete has been filled into the formwork around the filling detection sensor 11 based on the detection signal transmitted from the filling detection sensor 11. The filling status recognition processing unit 12 recognizes the concrete filling status using three stages, for example, "Not Filled" indicating that no concrete has been filled at all, "Filling" indicating that concrete is being filled, and "Filling Completed" indicating that concrete filling has been completed. The filling status recognition processing unit 12 transmits the recognition result to the filling display unit 13 and the first communication unit 15 at a predetermined interval.

[0022] The filling display unit 13 is, for example, an LCD display, and is provided in hardware integrated with the filling status recognition processing unit 12. The filling display unit 13 sequentially displays the concrete filling status based on the recognition results of the filling status recognition processing unit 12 in two dimensions (for example, a bar graph showing red for unfilled, yellow for filling, and green for completed filling). Note that the filling display unit 13 is not an essential component in the concrete pouring management system 1 of the present disclosure. In other words, the filling display unit 13 can be omitted.

[0023] The filling position information acquisition unit 14 acquires filling position information (three-dimensional position coordinates in the world coordinate system) that indicates the position where concrete is filled into the formwork from the concrete pouring pipe 6. As the pouring position information acquisition unit 14, for example, a GPS (Global Positioning System) device or a GNSS (Global Navigation Satellite System) device attached to the helmet of a worker (hereinafter referred to as a pouring worker) holding the concrete pouring pipe 6 and pouring concrete into the formwork, or a GPS function of a mobile terminal device carried by the pouring worker can be used.

[0024] The first communication unit 15 is connected to the filling status recognition processing unit 12 and the pouring position information acquisition unit 14 via wired or wireless communication so as to be able to communicate with them. The first communication unit 15 transmits the filling status recognized by the filling status recognition processing unit 12 and the filling position information acquired by the pouring position information acquisition unit 14 to the data management device 30 via the network 50 at a predetermined interval.

[0025] The compaction information acquisition unit 20 includes a compaction position information acquisition section 21, a drive information acquisition section 22, and a second communication section .

[0026] The compaction position information acquisition unit 21 acquires compaction position information (three-dimensional position coordinates in a world coordinate system) that indicates the position of the vibrator 7 that applies vibrations to the concrete filled in the formwork. The compaction position information acquisition unit 21 may be, for example, a GPS or GNSS device attached to the helmet of a worker (hereinafter, the compaction worker) who compacts the concrete with the vibrator 7, or a GPS function of a mobile terminal device carried by the compaction worker. The X and Y position coordinates of the vibrator 7 may be acquired based on the detection results of the GPS or GNSS device. The Z position coordinate of the vibrator 7 may be acquired by, in addition to the detection results of the GPS or GNSS device, capturing the position of a marking MK on the cable 7C of the vibrator 7 with a camera (not shown) installed on-site and estimating the insertion amount of the vibrator 7 into the formwork from the captured image data.

[0027] The drive information acquisition unit 22 acquires drive information, which is information as to whether or not the compaction worker is actually compacting the concrete by driving the vibrator 7. Whether or not the vibrator 7 is actually driving may be determined, for example, by collecting the driving sound of the vibrator 7 with a sound-collecting microphone (not shown) installed on-site, or may be determined based on whether or not the compaction worker has turned on a switch (not shown) when driving the vibrator 7.

[0028] The second communication unit 23 is connected to the compaction position information acquisition unit 21 and the compaction start time acquisition unit 22 so that they can communicate via wired or wireless communication. The second communication unit 23 transmits the compaction position information acquired by the compaction position information acquisition unit 21 and the drive information acquired by the compaction start time acquisition unit 22 to the data management device 30 via the network 50 at a predetermined interval.

[0029] The data management device 30 includes a server program, a database, and the like. The server program mainly executes processes such as a block division process for a 3D model of a concrete structure to be constructed at a construction site, and a 3D image generation process for generating and displaying 3D images showing the concrete filling status and compaction status. Details of the block division process and the 3D image generation and display process will be described later. The server program executes various processes and transmits the processing results to the user terminal device 40. The database stores data used by the server program for various processes, such as filling status and filling position information transmitted from the filling information acquisition unit 10, and compaction position information and drive information transmitted from the compaction information acquisition unit 20. The database also stores, as attribute information, various data that can be used for traceability of the construction history, such as the 3D model of the concrete structure, and the filling completion time and compaction completion time of each block of the 3D model.

[0030] The user terminal device 40 is a mobile terminal device such as a smartphone or tablet device carried by the staff and workers (pouring workers, compaction workers, etc.) at the construction site, or a personal computer installed in the management office of the construction site. The user terminal device 40 is equipped with a display device 41 such as a liquid crystal display. The display device 41 displays the filling status and compaction status transmitted from the data management device 30 superimposed on a 3D model of the concrete structure.

[0031] Incidentally, the filling status recognition processing unit 12 and the filling display unit 13 provided in the filling information acquisition unit 10 are generally installed in a location (away from the actual pouring work area) where they will not interfere with the pouring work in order to prevent contamination due to the adhesion of concrete. This poses a problem that pouring workers cannot know in real time whether the concrete has been reliably filled into the formwork, and another person in charge must be placed near the filling display unit 13. In addition, the filling display unit 13 only displays the filling status in two dimensions, which poses a problem that the three-dimensional positional relationship of the filling status cannot be grasped in real time.

[0032] The concrete pouring management system 1 according to this embodiment solves these problems by sequentially transmitting concrete pouring information (filling status, compaction status, etc.) acquired by the filling information acquisition unit 10 and the compaction information acquisition unit 20 to the data management device 30, and by generating a 3D image in which the pouring information is superimposed on a 3D model in the data management device 30, and displaying the image in real time on the display device 41 of the user terminal device 40 via the network 50. Details of the data management device 30 will be described below.

[0033] [Hardware configuration of data management device] FIG. 2 is a schematic diagram showing an example of the hardware configuration of the data management device 30 according to this embodiment.

[0034] As shown in FIG. 2, the data management device 30 includes a CPU 31, a ROM 32, and a RAM 33. The CPU 31, the ROM 32, and the RAM 33 form a so-called microcomputer. The data management device 30 also includes an auxiliary storage device 34 and a network IF 35. The CPU 31 executes various programs stored in the auxiliary storage device 34. The ROM 32 is a non-volatile memory that stores data and other information necessary for the CPU 31 to execute the various programs stored in the auxiliary storage device 34. The RAM 33 is a volatile memory that provides a working area into which the various programs stored in the auxiliary storage device 34 are expanded when the CPU 31 executes the various programs. The auxiliary storage device 34 is an auxiliary storage device that stores various programs and data used when the various programs are executed. The network IF 35 is a communication device that allows the data management device 30 to communicate with the filling information acquisition unit 10, the compaction information acquisition unit 20, the user terminal device 40, and the like via the network 50.

[0035] [Data management device software configuration] FIG. 3 is a schematic diagram showing an example of the software configuration of the data management device 30. As shown in FIG.

[0036] As shown in Figure 3, the data management device 30 has functional elements such as a 3D model memory unit 100, a block division processing unit 110, a data table generation and memory unit 120, a pouring information receiving unit 130, a compaction judgment unit 140, an attribute information storage processing unit 150, a 3D image generation and display processing unit 160, and a pouring notification processing unit 170.

[0037] The 3D model storage unit 100 stores a 3D model of a concrete structure to be constructed at a construction site. Here, the 3D model is design data that represents the shape and the like of the concrete structure in three dimensions, and for example, a CIM (Construction Information Modeling) model or a BIM (Building Information Modeling) model can be used. The 3D model may be created by the data management device 30, or may be created by an information processing device separate from the data management device 30. When created by a separate information processing device, the 3D model may be stored in the 3D model storage unit 100 via the network 50 or a storage medium.

[0038] The block division processing unit 110 performs a block division process to divide the 3D model stored in the 3D model storage unit 100 into multiple blocks. The 3D model is design data for a concrete structure, and the elements that make up the 3D model, such as the deck, beams, and columns, are often not sized appropriately for concrete pouring management. The block division processing unit 110 executes a block division process to divide the 3D model into multiple blocks of a size appropriate for concrete pouring management and assign a control number to each block. Here, the size appropriate for concrete pouring management is not particularly limited, but, as an example, it is desirable to set it based on a size that satisfies the allowable concrete pouring time interval and ensures workability during pouring. The allowable pouring time interval may be determined based on the outside temperature at the construction site, etc.

[0039] FIG. 4 is a schematic diagram illustrating an example of a block division process. In FIG. 4, the symbol MD indicates a portion of a three-dimensional model of a concrete structure. The block division processor 110 first divides the three-dimensional model MD into multiple blocks B1, B2, etc. suitable for pouring management. The block division processor 110 then divides each of the divided blocks B1, B2, etc. into multiple layers in the height direction. In the example shown in FIG. 4, each block B1, B2, etc. is divided into three layers in the height direction. After dividing each block B1, B2, etc. in the height direction, the block division processor 110 assigns a control number to each layer. For example, the lowest layer L1 of the first block B1 is assigned a control number such as "B1-L1," the second-lowest layer L2 is assigned a control number such as "B1-L2," and the third-lowest layer L3 is assigned a control number such as "B1-L3." The number of layers into which each block B1, B2, etc. is divided in the height direction is basically determined according to the number of locations where concrete filling confirmation is required (hereinafter referred to as filling confirmation locations). That is, in one preferred embodiment, at least one filling detection sensor 11 (shown in FIG. 1) is installed in each location within the formwork corresponding to each layer L1, L2, etc. of each block B1, B2, etc. Note that, for example, in the top layer, workers may be able to grasp the filling status by visual inspection or based on the discharge from the concrete pouring pipe 6. For this reason, the technology disclosed herein may include an embodiment in which a filling detection sensor 11 is not installed for a specific block or layer.

[0040] The data table generating and storing unit 120 generates and stores a data table that associates the filling detection sensors 11 actually installed at the construction site with the control numbers B1-L1, B1-L2, etc. of each layer L1, L2, etc. assigned by the block division processing unit 110. FIG. 5 is an example of a data table DT generated by the data table generating and storing unit 120. The data table generating and storing unit 120 automatically assigns serial numbers (S1, S2, etc.) corresponding to the number of filling detection sensors 11 actually installed at the construction site to the "sensor type" column of the data table DT. Next, the data table generating and storing unit 120 stores the control numbers B1-L1, B1-L2, etc. assigned by the block division processing unit 110 to the serial numbers of the filling detection sensors 11 in the "block type" column of the data table DT. Additionally, the data table generating and storing unit 120 stores the three-dimensional position information of each layer L1, L2, . . . extracted from the three-dimensional model in the "position information" column of the data table DT in association with the management number.

[0041] The above-described storage process of the 3D model MD, block division process, and data table DT generation process are preparatory processes carried out before starting concrete pouring work at the construction site. Once all of these preparatory processes are completed and the filling detection sensors 11 are installed at the construction site at filling confirmation locations within the formwork (locations corresponding to each layer L1, L2, etc.), the concrete pouring management system 1 enters a state where it can start concrete pouring management (i.e., a standby state).

[0042] When the pouring information receiving unit 130 receives a request to start pouring management after the aforementioned preparation process is completed and the installation work of the filling detection sensor 11 at the construction site is finished, the pouring information receiving unit 130 sequentially receives filling status and filling position information transmitted at a predetermined interval from the filling information acquisition unit 10. In addition, after receiving the request to start pouring management, when the pouring work of concrete into the formwork is started, the pouring information receiving unit 130 sequentially receives compaction position information and drive information transmitted at a predetermined interval from the compaction information acquisition unit 20. The request to start pouring management may be input by a worker or staff member at the construction site using the user terminal device 40. The pouring information receiving unit 130 sequentially transmits the filling status and filling position information received from the filling information acquisition unit 10 to the attribute information storage processing unit 150 and the 3D image generation and display processing unit 160, which will be described later. In addition, the pouring information receiving unit 130 sequentially transmits the compaction position information and drive information received from the compaction information acquisition unit 20 to the compaction determination unit 140 described later.

[0043] The compaction determination unit 140 performs a compaction determination to determine whether the concrete in the formwork has been compacted, based on the compaction position information and drive information received by the pouring information receiving unit 130. The compaction determination unit 140 identifies the layers L1, L2, etc. of the blocks B1, B2, etc. into which the vibrator 7 is actually inserted, by referring to the data table DT (shown in FIG. 5) based on the compaction position information. After identifying the layers L1, L2, etc. into which the vibrator 7 is inserted, the compaction determination unit 140 determines whether the vibrator 7 is actually operating, based on the drive information transmitted from the pouring information receiving unit 130 (such as the drive sound of the vibrator 7 and information on the switch ON operation by the compaction worker).

[0044] When the compaction determination unit 140 determines that the vibrator 7 is being driven, the compaction determination unit 140 calculates the cumulative driving time T SUM The driving of the vibrator 7 may be either continuous or intermittent. The compaction determination unit 140 calculates the cumulative driving time T SUMWhen the cumulative driving time T reaches a predetermined threshold time Tv, the compaction determination unit 140 determines that the concrete in the layers L1, L2, etc. into which the vibrator 7 is inserted has been compacted (i.e., "compaction completed"). SUM reaches a predetermined threshold time Tv, the compaction determination unit 140 determines that the concrete in the layers L1, L2, etc. into which the vibrator 7 is inserted is not compacted (i.e., "compaction incomplete"). The compaction determination unit 140 sequentially transmits the compaction determination results to the attribute information storage processing unit 150 and the 3D image generation and display processing unit 160.

[0045] The attribute information storage processor 150 acquires the concrete filling start time and filling completion time for each layer L1, L2, etc. based on the filling status received by the pouring information receiver 130. Furthermore, upon acquiring the concrete filling start time and filling completion time for each layer L1, L2, etc., the attribute information storage processor 150 stores the filling start time and filling completion time in association with the management number in the "filling information" column of the data table DT, as shown in FIG. 5. Additionally, the attribute information storage processor 150 acquires the concrete compaction start time and compaction completion time for each layer L1, L2, etc. based on the compaction assessment result of the compaction assessment unit 140. Furthermore, when the attribute information storage processing unit 150 acquires the compaction start time and compaction completion time of the concrete for each layer L1, L2, etc., it stores the compaction start time and compaction completion time in the "compaction information" column of the data table DT in association with the control number, as shown in Fig. 5. In this way, by storing the concrete filling start time and filling completion time of each layer L1, L2, etc., as well as the compaction start time and compaction completion time, etc., in association with the control number, this attribute information can be used for traceability of the construction history of the concrete structure.

[0046] The 3D image generation and display processing unit 160 executes a 3D image generation and display process that displays the concrete filling status and compaction status in 3D in real time on the display device 41 of the user terminal device 40. When the 3D image generation and display processing unit 160 receives a request to start pouring management from a worker or the like at the construction site via the user terminal device 40, the pouring information receiving unit 130 identifies blocks B1, B2, etc. into which concrete will actually be poured by referring to the data table DT based on the filling position information received from the filling information acquisition unit 10. An example of the 3D image generation and display process when block B1 is identified will be described below. The same process is performed when other blocks B2, etc. are identified, so a description of those processes will be omitted.

[0047] FIG. 6 shows an example of an image G1 displayed on the display device 41 of the user terminal device 40 when the 3D image generation and display processing unit 160 receives a request to start pouring management. At the time the request to start pouring management is received, concrete has not yet been poured into the formwork. Therefore, the filling status of each of the layers L1 to L3 received by the pouring information receiving unit 130 from the filling information acquisition unit 10 is "unfilled." In this case, the 3D image generation and display processing unit 160 applies a first color (e.g., red) to the filling indicators IGF1 to IGF3, which are displayed superimposed on each of the layers L1 to L3 of the 3D model MD, indicating that concrete is not yet filled. Although the shape of the filling indicators IGF1 to IGF3 is shown as a roughly cubic shape in FIG. 6, any other shape may be used as long as it can be displayed superimposed on each of the layers L1 to L3. While the filling indicators IGF1 to IGF3 are displayed in the first color indicating that they are not yet filled, the layers L1 to L3 of the three-dimensional model MD are displayed in a transparent state indicating that concrete has not yet reached them.

[0048] When the pouring of concrete causes the filling status of layer L1 received by the pouring information receiving unit 130 from the filling information acquisition unit 10 to change from "unfilled" to "filling," the 3D image generation and display processing unit 130 displays image G2 shown in FIG. 7 on the display device 41 of the user terminal device 40. In this case, the 3D image generation and display processing unit 160 applies a second color (e.g., orange) to the filling indicator IGF1 corresponding to layer L1 of the 3D model, which is different from the first color indicating that concrete is being poured. In addition, the 3D image generation and display processing unit 160 switches the display of the entire layer L1 of the 3D model from a transparent state to a semi-transparent state indicating that the concrete has arrived.

[0049] Furthermore, when the 3D image generation and display processing unit 160 switches the layer L1 of the 3D model MD to a semi-transparent state, it displays a compaction indicator IGC superimposed on the layer L1. This compaction indicator IGC has a generally cylindrical shape that schematically indicates the range over which vibrations are transmitted from the vibrator 7 to the concrete. When the concrete filling status of layer L1 is "filling," the concrete compaction is not complete. In this case, the 3D image generation and display processing unit 160 assigns a third color (e.g., yellow) different from the first and second colors to the compaction indicator IGC displayed superimposed on layer L1 of the 3D model, indicating that the concrete compaction is not yet complete.

[0050] As the pouring of concrete continues, when the filling status of layer L1 received by the pouring information receiving unit 130 from the filling information acquisition unit 10 changes from "filling in progress" to "filling completed," the 3D image generation and display processing unit 160 displays image G3 shown in FIG. 8 on the display device 41 of the user terminal device 40. In this case, the 3D image generation and display processing unit 160 applies a fourth color (e.g., green) different from the first to third colors to the filling indicator IGF1 corresponding to layer L1 of the 3D model, indicating that filling with concrete has been completed. At this time, if the determination result of the compaction determination unit 140 is "compaction incomplete," the 3D image generation and display processing unit 160 continues to display the compaction indicator IGC in the third color, as shown in FIG. 8.

[0051] As the pouring of concrete continues, when the filling status of layer L2 received by the pouring information receiving unit 130 from the filling information acquisition unit 10 changes from "unfilled" to "filling," the 3D image generation and display processing unit 160 displays image G4 shown in FIG. 9 on the display device 41 of the user terminal device 40. In this case, the 3D image generation and display processing unit 160 applies a second color to the filling indicator IGF2 corresponding to layer L2 of the 3D model. Furthermore, if the compaction determination unit 140 determines that the compaction of layer 1 is "compaction completed," the 3D image generation and display processing unit 160 applies a fifth color (e.g., blue) to the compaction indicator IGC located on layer L1, as shown in FIG. 9, which is different from the first to fourth colors indicating that the compaction of the concrete is completed, and switches the display of the entire layer L1 of the 3D model from a semi-transparent state to an opaque state. Thereafter, the 3D display image generation processing unit 160 repeatedly executes the 3D image generation and display process, appropriately switching the colors of the filling indicators IGF2, 3 and the compaction indicator IGC, until the concrete filling of the top layer L3 is completed and the concrete compaction is completed.

[0052] In this embodiment, the concrete filling status and compaction status within the formwork are sequentially displayed on the display device 41 of the user terminal device 40 carried by the concrete pourer at the construction site. This allows the concrete pourer to grasp the filling status and compaction status in real time while continuing work. This eliminates the need to check the filling display unit 13, which is installed at a location distant from the actual work area, improving work efficiency. Furthermore, since there is no need to assign additional personnel to the filling display unit 13, labor savings can be achieved. Furthermore, since there is no need to travel to the location where the filling display unit 13 is installed, risks and time waste associated with travel can be effectively reduced. Furthermore, since the concrete filling status and compaction status are displayed in three dimensions on the display device 41, the three-dimensional positional relationship of the filling status and compaction status can be easily grasped.

[0053] The pouring notification processor 170 performs pouring notification processing to notify the user that the pouring start time has arrived when it is time to pour concrete into each layer L1-L3. The pouring notification processor 170 starts counting time, for example, when the filling status of layer L1 received by the pouring information receiver 130 from the filling information acquisition unit 10 changes from "filling in progress" to "filling completed" and the assessment result of layer L1 by the compaction assessment unit 140 changes from "compaction incomplete" to "compaction completed." When the measured time reaches a predetermined time, the pouring notification processor 170 notifies the user that the time to pour concrete into layer L1 has arrived. The notification may be made by displaying a message on the display device 41 of the user terminal device 40 or by voice from a speaker provided in the user terminal device 40. Automatically managing the concrete pouring time in this way eliminates the need for workers to take notes on the time, which is a conventional task performed by construction site workers. That is, convenience is improved.

[0054] [Preparation process flow] FIG. 10 is a flow diagram illustrating a preparation process for concrete pouring management using the concrete pouring management system 1 according to this embodiment.

[0055] In step S100, a three-dimensional model MD of the concrete structure to be constructed at the construction site is created and stored in the data management device 30. The three-dimensional model MD may be created by the data management device 30, or may be created by an information processing device separate from the data management device 30.

[0056] Next, in step S110, the CPU 31 of the data management device 30 divides the three-dimensional model MD into a plurality of blocks B1, B2, etc. that are suitable for pouring management, and divides each block B1, B2, etc. into a plurality of layers L1, L2, etc. in the vertical direction, and performs a block division process in which management numbers B1-L1, B1-L2, etc. are assigned to each layer.

[0057] Next, in step S120, the CPU 31 of the data management device 30 determines whether each layer L1, L2, etc. matches the filling confirmation location. If each layer L1, L2, etc. matches the filling confirmation location (Yes), the CPU 31 of the data management device 30 proceeds to the processing of step S140. On the other hand, if each layer L1, L2, etc. does not match the filling confirmation location (No), the CPU 31 of the data management device 30 proceeds to the processing of step S130.

[0058] In step S130, the CPU 31 of the data management device 30 re-divides the layers L1, L2, etc. that do not match the filling confirmation points so that they match the filling confirmation points and assigns new management numbers. After assigning the management numbers, the CPU 31 of the data management device 30 proceeds to the processing of step S140.

[0059] In step S140, the CPU 31 of the data management device 30 generates a data table DT that associates the serial numbers (S1, S2, etc.) of the filling detection sensors 11 actually installed at the construction site, the serial numbers B1-L1, B1-L2, etc. of each layer L1, L2, etc., with the three-dimensional position information of each layer L1, L2, etc. extracted from the three-dimensional model. Next, in step S150, the CPU 31 of the data management device 30 stores the generated data table DT, and the preparation process ends.

[0060] [Pouring management process flow] Fig. 11 is a flow diagram illustrating the process of concrete pouring management using the concrete pouring management system 1 according to this embodiment. The flow shown in Fig. 11 starts after the preparation process shown in Fig. 10 is completed and the filling detection sensor 11 is installed at the filling confirmation point in the formwork at the construction site.

[0061] In step S200, the CPU 31 of the data management device 30 determines whether or not a request to start pouring management has been received. If a request to start pouring management has been received (Yes), the CPU 31 of the data management device 30 proceeds to the processing of step S210. On the other hand, if a request to start pouring management has not been received (No), the CPU 31 of the data management device 30 returns (ends) this routine.

[0062] In step S210, the CPU 31 of the data management device 30 displays on the display device 41 of the user terminal device 40 an image G1 (shown in FIG. 6) in which the filling indicators IGF1 to IGF3 superimposed on each layer L1 to L3 are colored a first color (e.g., red) to indicate that concrete has not been filled, and each layer L1 to L3 of the three-dimensional model is made transparent to indicate that concrete has not yet reached it.

[0063] In step S220, the CPU 31 of the data management device 30 determines whether the filling status of the bottom layer L1 has switched from "unfilled" to "filling." If the filling status has not switched from "unfilled" to "filling" (No), the CPU 31 of the data management device 30 returns to the processing of step S210. That is, the CPU 31 of the data management device 30 continues to display the image G1. On the other hand, if the filling status has switched from "unfilled" to "filling" (Yes), the CPU 31 of the data management device 30 proceeds to the processing of step S230.

[0064] In step S230, the CPU 31 of the data management device 30 changes the filling indicator IGF1 corresponding to layer L1 to a second color (e.g., orange) indicating that concrete is being filled, and displays an image G2 (shown in Figure 7) on the display device 41 of the user terminal device 40, which makes layer L1 of the three-dimensional model translucent to indicate that the concrete has arrived.

[0065] In step S240, the CPU 31 of the data management device 30 determines whether the filling status of layer L1 has switched from "filling" to "filling complete." If the filling status of layer L1 has not switched to "filling complete" (No), that is, if it is "filling," the CPU 31 of the data management device 30 returns to the processing of step S230. That is, the CPU 31 of the data management device 30 continues to display the image G2. On the other hand, if the filling status of layer L1 has switched to "filling complete" (Yes), the CPU 31 of the data management device 30 proceeds to the processing of step S250.

[0066] In step S250, the CPU 31 of the data management device 30 displays an image G3 (shown in FIG. 8) on the display device 41 of the user terminal device 40, in which the filling indicator IGF1 corresponding to layer L1 of the three-dimensional model is colored a fourth color (e.g., green) to indicate that concrete filling has been completed, and the compaction indicator IGC displayed superimposed on layer L1 of the three-dimensional model is colored a third color (e.g., yellow) to indicate that compaction has not been completed.

[0067] In step S260, the CPU 31 of the data management device 30 calculates the cumulative driving time T SUM It is determined whether the cumulative driving time T SUM If the cumulative driving time T has not reached the predetermined threshold time Tv (No), the CPU 31 of the data management device 30 determines that the compaction of the concrete is not completed, and returns to the process of step S250. That is, the CPU 31 of the data management device 30 continues to display the image G3. On the other hand, if the cumulative driving time T SUM When the time reaches the predetermined threshold time Tv (Yes), the CPU 31 of the data management device 30 determines that the compaction of the concrete is completed, and proceeds to the processing of step S270.

[0068] In step S270, the CPU 31 of the data management device 30 changes the compaction indicator IGC located on layer L1 to a fifth color (e.g., blue) indicating that concrete compaction has been completed, and displays an image G4 (shown in Figure 9) on the display device 41 of the user terminal device 40, which makes the entire layer L1 of the three-dimensional model opaque.

[0069] In step S280, the CPU 31 of the data management device 30 determines whether or not the three-dimensional image generation and display process for the filling status and compaction status has been performed for all blocks B1, B2, etc. of the three-dimensional model MD. If the three-dimensional image generation and display process for the filling status and compaction status has not been performed for all blocks B1, B2, etc. (No), that is, if there are blocks B2, etc. for which the three-dimensional display process has not been performed, the CPU 31 of the data management device 30 returns to the process of step S210 and starts the three-dimensional image generation and display process for the remaining blocks B2, etc. On the other hand, if the three-dimensional image generation and display process for the filling status and compaction status has been performed for all blocks B1, B2, etc. (Yes), the CPU 31 of the data management device 30 returns (ends) this routine.

[0070] The above describes the pouring management system and pouring management method related to this embodiment, but this disclosure is not limited to the above embodiment, and various modifications are possible as long as they do not deviate from the purpose of this disclosure.

[0071] For example, in the above embodiment, the filling status recognition processing unit 12 is described as being included in the filling information acquisition unit 10, but it can also be provided in the data management device 30. In this case, the detection signal of the filling detection sensor 11 can be directly transmitted from the first communication unit 15 to the data management device 30 via the network 50. Furthermore, while the data management device 30 has been described as being installed in a remote location away from the construction site, the technology disclosed herein does not preclude the data management device 30 from being installed in a management office or the like at the construction site. Furthermore, the display device 41 of the user terminal device 40 is not limited to a liquid crystal display of a mobile terminal device or the like, but may also be goggles worn by workers. Furthermore, the block division process has been described as dividing each block B1, B2, etc. into multiple layers L1, L2, etc., but blocks with only one filling confirmation location (the location where the filling detection sensor 11 is installed) do not need to be divided into layers. Furthermore, in the above embodiment, the filling status and compaction status are described as being displayed in three dimensions on the display device 41, but these filling status and compaction status can also be displayed in two dimensions on the display device 41. In addition, in the above embodiment, concrete pouring management has been described as an example, but the technology disclosed herein can be widely applied to the pouring management of various cement-based compositions such as mortar, cement milk, etc. [Explanation of symbols]
