Below, the embodiments for carrying out the present invention will be described in detail by way of example with reference to the drawings. However, the configurations, numerical values, processing flows, functional elements, etc. described in the following embodiments are merely examples, and may be freely modified or altered, and are not intended to limit the technical scope of the present invention to the following description.

[First embodiment]
A concrete pouring management device according to a first embodiment of the present invention will be described with reference to Figures 1A to 5B. The concrete pouring management device 100 is a device for consistently carrying out a process from planning a pouring plan for pouring concrete into a structure to pouring management for actually pouring the concrete according to the planned pouring plan.

First, referring to Figures 1A and 1B, an overview of the operation of the concrete pouring management device 100 will be described. As shown in Figure 1A, when pouring concrete into a structure of a certain size, a concrete pouring plan is drawn up, and the concrete is transported and poured according to the drawn up pouring plan. The concrete pouring management device 100 is a device that manages a series of processes from drawing up the pouring plan to transporting and pouring the concrete.

The concrete pouring management device 100 creates a pouring plan for a structure. The concrete pouring management device 100 first acquires three-dimensional design information 170 for the structure, which is generated using a three-dimensional CAD (Computer-Aided Design) or the like. The structure is of a certain size, and concrete is poured in several steps.

Then, the concrete pouring management device 100 divides the acquired three-dimensional design information 170 into pouring blocks 171 of a predetermined size. The size of the pouring blocks 171 is determined according to, for example, the amount (volume) of concrete that can be poured in one day.

When the concrete is divided into pouring blocks 171 of a predetermined size, the concrete pouring management device 100 divides each of the divided pouring blocks 171 into small blocks 172 of a predetermined size to generate the small blocks 172. The size of the small blocks 172 is determined, for example, according to the amount of concrete that can be transported by one agitator truck 140. Then, information (division data) of the generated small blocks 172 is stored in association with the three-dimensional design information 170. In other words, the three-dimensional design information 170 includes information on the pouring blocks 171 and the small blocks 172.

Next, the concrete pouring management device 100 assigns a block number to each of the generated small blocks 172, indicating the order in which the concrete will be poured. The concrete is poured based on the assigned block numbers. In this way, once a concrete pouring plan for the structure has been drawn up, the concrete is poured according to the drawn up pouring plan.

The manufactured ready-mix concrete is transported from the ready-mix concrete manufacturing plant by an agitator truck 140, and the time from manufacturing to completion of pouring is regulated by JIS standards and concrete standard specifications. In other words, pouring of concrete for structures is carried out under strict time management.

The concrete pouring management device 100 records the time elapsed between when the ready-mixed concrete shipped from the manufacturing plant is poured at the pouring location where the pump truck 150 is located at the construction site 160, thereby managing the concrete so that the above-mentioned standards are met. In other words, when the agitator truck 140 leaves the manufacturing plant and arrives at the construction site 160, it follows the instructions of the on-site guide to move to the stopping position of the pump truck 150 to which the ready-mixed concrete it has been transported will be supplied. The driver of the agitator truck 140 then begins unloading the ready-mixed concrete. Once the unloading operation has begun, the ready-mixed concrete that has been transported is supplied from the pump truck 150 to the small block where it will be poured, and the pouring of the concrete is completed.

Ready-mixed concrete transported from a manufacturing plant is manufactured under various conditions, and the concrete pouring management device 100 manages these conditions as ready-mixed concrete information. The ready-mixed concrete information includes, for example, information such as the mixing ratio of raw materials, the production volume, the date of manufacture, and the shipping time. The concrete pouring management device 100 then records the start and end times of unloading work, the start and end times of concrete pouring, and the like, in association with the ready-mixed concrete information, along with the identification number of the agitator vehicle 140 that transported the work. The identification number of the agitator vehicle 140 is, for example, the vehicle registration number (license plate number) or vehicle number of the agitator vehicle 140.

The concrete pouring management device 100 also records the block number of the small block into which the concrete has been poured, together with the identification number of the agitator vehicle 140, in association with the ready-mix concrete information. The ready-mix concrete information associated with the small block number is, for example, the information shown in FIG. 1B, but is not limited to this. In this way, the concrete pouring management device 100 records ready-mix concrete information, shipping time, arrival time, pouring start time, and pouring end time in association with the block number of the small block, making it possible to consistently manage the entire process from the production of ready-mix concrete to pouring.

Next, the configuration of the concrete pouring management device 100 will be described with reference to FIG. 2. The concrete pouring management device 100 has an acquisition unit 201, a small block generation unit 202, and a block number assignment unit 203. The concrete pouring management device 100 further has a shipment detection unit 204, a shipment time recording unit 205, an arrival detection unit 206, an arrival time recording unit 207, a small block information recording unit 208, a pouring start time recording unit 209, an unloading completion determination unit 210, and a pouring completion time recording unit 211.

The acquisition unit 201 acquires three-dimensional design information of the structure into which the ready-mix concrete will be poured. As described above, the three-dimensional design information is design data of the structure designed using three-dimensional CAD.

The small block generating unit 202 divides the acquired three-dimensional design information into pouring blocks of a predetermined size, and divides each divided pouring block into small blocks of a predetermined size to generate the small blocks. The pouring blocks are, for example, blocks divided into multiple layers of a structure according to the amount of concrete that can be transported in a day. The small blocks are then generated by further dividing the pouring blocks into smaller sized blocks. For example, the size of the small blocks is determined by the amount of concrete that can be transported by one agitator truck 140.

The block number assignment unit 203 assigns a block number indicating the order in which the concrete will be poured to each of the generated small blocks. In other words, the block number assignment unit 203 assigns a block number to each of the small blocks included in the acquired three-dimensional design information, which is capable of identifying each small block and indicates the order in which the concrete will be poured.

The shipment detection unit 204 detects the shipment of ready mixed concrete by the agitator vehicle 140 that transports ready mixed concrete manufactured at the ready mixed concrete manufacturing plant to the concrete construction site 160. The method of shipment detection is, for example, by the shipment detection unit 204 receiving a shipment signal indicating that ready mixed concrete has been shipped from a mobile terminal installed at the manufacturing plant or a mobile terminal carried by an employee of the manufacturing plant. The shipment detection unit 204 receives a shipment signal transmitted by, for example, an employee of the manufacturing plant operating a mobile terminal, and is thereby able to detect the shipment of ready mixed concrete. The mobile terminal may transmit an identification number for identifying the agitator vehicle 140 to the shipment detection unit 204 together with the shipment signal.

Another method of detecting shipments is to use an imaging unit such as a camera installed in a ready-mix concrete manufacturing plant to capture an image of a specified imaging range of the manufacturing plant, and to capture and detect an agitator vehicle 140 that enters or passes through the specified imaging range. The specified imaging range of the manufacturing plant is, for example, the entrance and exit area of the manufacturing plant.

Then, the shipment detection unit 204 reads an identification number for identifying the agitator vehicle 140, for example, from the image captured by the imaging unit. The identification number that is read is the vehicle registration number (license plate number) or vehicle number of the agitator vehicle 140. Then, when the identification number of the agitator vehicle 140 is read, the shipment detection unit 204 detects the shipment of ready-mix concrete by the agitator vehicle 140.

The shipping time recording unit 205 records the time when the shipping is detected by the shipping detection unit 204 in association with the ready-mix concrete information including information about ready-mix concrete. When the shipping of ready-mix concrete is detected by a mobile terminal, the shipping time recording unit 205 records the time when the shipping detection unit 204 receives the shipping signal as the shipping time of the ready-mix concrete. When the shipping of ready-mix concrete is detected by the imaging unit, the shipping time recording unit 205 records the time when the identification number of the agitator car 140 is read by the shipping detection unit 204 as the shipping time of the ready-mix concrete. The shipping time recording unit 205 may record the identification number of the agitator car 140 transmitted from a mobile terminal carried by an employee of the manufacturing plant, or the identification number read by the shipping detection unit 204, in association with the ready-mix concrete information together with the shipping time.

The arrival detection unit 206 detects the arrival of the agitator vehicle 140 at the construction site 160. The arrival detection unit 206 detects the arrival of the agitator vehicle 140, for example, in the following manner. The arrival detection unit 206 receives an arrival signal indicating the arrival of the agitator vehicle 140 at the construction site 160 from a mobile terminal placed at the construction site 160. The arrival signal is transmitted from a mobile terminal such as a tablet terminal carried by a worker at the construction site 160.

For example, when the agitator vehicle 140 arrives at the construction site 160, the worker at the construction site 160 operates a mobile terminal to select the identification number of the agitator vehicle 140 that has arrived from, for example, a list of agitator vehicles 140 transporting ready-mixed concrete displayed on the display. Then, a signal indicating that the agitator vehicle 140 selected from the list has arrived at the construction site 160 is transmitted from the mobile terminal to the arrival detection unit 206. The arrival detection unit 206 then detects the arrival of the agitator vehicle 140 at the construction site 160 by receiving the transmitted arrival signal. In addition, for example, an entry/exit detection sensor may be installed near the entrance/exit gate of the construction site 160, and the arrival of the agitator vehicle 140 at the pouring location may be detected using this entry/exit detection sensor. The mobile terminal may transmit an identification number for identifying the agitator vehicle 140 to the arrival detection unit 206 together with the arrival signal.

Furthermore, an imaging unit may be arranged at the construction site 160 to detect the arrival of the agitator vehicle 140 at the construction site 160. That is, the arrival detection unit 206 acquires an image of the agitator vehicle 140 from the imaging unit arranged at the construction site 160. Here, the image taken at the construction site 160 may be an image (video) taken at a predetermined time interval or a still image taken at a predetermined timing. In addition, the imaging unit may take an image of the agitator vehicle 140 at a predetermined angle of view, and may take an image of one or more agitator vehicles 140 in one frame. The imaging unit may take an image of the front, side, or back of the agitator vehicle 14, or a combination of these positions, so that they fit into one frame.

Then, the arrival detection unit 206 reads the identification number of the agitator vehicle 140 from the acquired captured image. The arrival detection unit 206 detects the arrival of the agitator vehicle 140 by reading the identification number of the agitator vehicle 140, for example, by performing OCR (Optical Character Recognition) processing on the captured image.

The arrival time recording unit 207 records the time when the arrival is detected by the arrival detection unit 206 as the arrival time of the ready-mixed concrete together with the identification number of the agitator vehicle 140 in association with the ready-mixed concrete information. When the arrival of the agitator vehicle 140 is detected by the mobile terminal, the arrival time recording unit 207 records the time when the arrival detection unit 206 received the arrival signal as the arrival information of the agitator vehicle 140. When the arrival of the agitator vehicle 140 is detected by the imaging unit, the arrival time recording unit 207 records the time when the arrival detection unit 206 reads the identification number of the agitator vehicle 140 as the arrival time of the agitator vehicle 140. The arrival time recording unit 207 may record the identification number of the agitator vehicle 140 transmitted from the mobile terminal carried by the worker at the construction site 160, or the identification number read by the arrival detection unit 206, in association with the arrival time and ready-mixed concrete information.

The small block information recording unit 208 records the block number of the small block into which the transported ready-mixed concrete is poured, together with the identification number, in association with the ready-mixed concrete information. That is, the ready-mixed concrete transported to the construction site 160 is unloaded at the construction site 160 and supplied to the pump vehicle 150. The concrete is then poured from the tip of the boom of the pump vehicle 150 into the small block to be poured. In this case, the small block information recording unit 208 records the block number of the small block into which the concrete transported by the agitator vehicle 140 is poured, together with the identification number of the agitator vehicle 140, in association with the ready-mixed concrete information.

The casting start time recording unit 209 records the arrival time as the concrete casting start time, in association with the ready-mixed concrete information, together with the identification number and block number. When the agitator truck 140 arrives at the construction site 160, the unloading of the ready-mixed concrete it has transported begins immediately. Then, when the unloading of the ready-mixed concrete begins, the unloaded ready-mixed concrete is supplied to the pump truck 150 and poured into the small block into which it is to be poured. In this way, the ready-mixed concrete transported by the agitator truck 140 is poured into the small block into which it is to be poured as soon as it arrives at the construction site 160, so the casting start time recording unit 209 records the arrival time of the agitator truck 140 at the construction site 160 as the concrete casting start time.

The unloading completion determination unit 210 determines the completion of unloading of ready-mix concrete. The completion of unloading is determined, for example, when a worker at the construction site 160 uses a mobile terminal or the like to send an unloading completion signal indicating the completion of unloading, and the unloading completion determination unit 210 receives the unloading completion signal.

Alternatively, the unloading completion determination unit 210 may detect that the agitator vehicle 140 is no longer visible in the image captured by the imaging unit installed at the construction site 160 while the unloading operation is in progress. In other words, when the unloading of ready-mix concrete from the agitator vehicle 140 is completed, the agitator vehicle 140 moves away from the position where the pump vehicle 150 is parked so that the next agitator vehicle 140 can unload. Therefore, when the agitator vehicle 140 moves away from the pump vehicle 150, it can be determined that the unloading by the agitator vehicle 140 has been completed, and the unloading completion determination unit 210 uses this to determine the completion of unloading.

When the unloading completion determination unit 210 is determining the completion of unloading using the imaging unit, it determines that unloading by the agitator vehicle 140 is continuing, for example, as long as the same identification number continues to be recognized (extracted) from the captured image. Furthermore, the unloading completion determination unit 210 determines that unloading is completed when the same identification number cannot be recognized from the captured image for a predetermined period of time.

The pouring end time recording unit 211 records the time when the unloading end determination unit 210 determines that the unloading of the ready-mixed concrete has ended as the concrete pouring end time, in association with the identification number and the block number, and with the ready-mixed concrete information. In other words, when the unloading operation from the agitator truck 140 ends, the supply of concrete from the pump truck 150 to the small blocks also ends immediately. Therefore, the pouring end time recording unit 211 records the time when the unloading end determination unit 210 determines that the unloading has ended as the concrete pouring end time.

An example of a concrete information table 301 held by the concrete pouring management device 100 will be described with reference to FIG. 3. The concrete information table 301 stores concrete information 312 and small block information 313 in association with an identification number 311. The identification number 311 is a number for identifying the agitator vehicle 140, and is the vehicle registration number or vehicle number of the agitator vehicle 140. The concrete information 312 is information about concrete manufactured at a ready-mix concrete manufacturing plant, and includes the load amount, shipping time, arrival time, etc. The small block information 313 is information about the generated small blocks, and includes the block number and position, etc.

The hardware configuration of the concrete pouring management device 100 will be described with reference to FIG. 4. The CPU (Central Processing Unit) 410 is a processor for arithmetic control, and executes a program to realize each functional configuration of the concrete pouring management device 100 in FIG. 2. The CPU 410 has multiple processors and may execute different programs, modules, tasks, threads, etc. in parallel. The ROM (Read Only Memory) 420 stores fixed data such as initial data and programs, and other programs. The network interface 430 communicates with other devices, etc. via a network. The CPU 410 is not limited to one, and may be multiple CPUs or may include a GPU (Graphics Processing Unit) for image processing. It is also preferable that the network interface 430 has a CPU independent of the CPU 410 and writes or reads transmission and reception data in an area of the RAM (Random Access Memory) 440. It is also preferable to provide a direct memory access controller (DMAC) (not shown) that transfers data between the RAM 440 and the storage 450. Furthermore, the CPU 410 recognizes that data has been received or transferred to the RAM 440 and processes the data. The CPU 410 also prepares the processing results in the RAM 440 and leaves subsequent transmission or transfer to the network interface 430 and the DMAC.

Storage 450 stores a database, various parameters, or the following data or programs required to realize this embodiment. Storage 450 stores concrete information table 301. Concrete information table 301 is a table that manages the relationship between identification number 311 and concrete information 312, etc., shown in FIG. 3.

Storage 450 further stores an acquisition module 451, a small block generation module 452, a block number assignment module 453, a shipment detection module 454, a shipment time recording module 455, an arrival detection module 456, and an arrival time recording module 457. Storage 450 further stores a small block information recording module 458, a concrete pouring start time recording module 459, an unloading completion determination module 470, and a concrete pouring completion time recording module 471.

The acquisition module 451 is a module that acquires three-dimensional design information of a structure. The small block generation module 452 is a module that divides the acquired three-dimensional design information into pouring blocks of a predetermined size, and divides each of the divided pouring blocks into blocks of a predetermined size to generate small blocks. The block number assignment module 453 is a module that assigns a block number indicating the order in which the concrete is poured to each of the generated small blocks. The shipment detection module 454 is a module that detects the shipment of ready-mixed concrete by the agitator truck 140 that transports the ready-mixed concrete manufactured at the ready-mixed concrete manufacturing plant to the concrete construction site 160. The shipment time recording module 455 is a module that records the time when the shipment is detected in association with ready-mixed concrete information including information about the ready-mixed concrete.

The arrival detection module 456 is a module that detects the arrival of the agitator truck 140 at the construction site 160. The arrival time recording module 457 records the time of arrival detected as the arrival time of the ready-mixed concrete together with the identification number of the agitator truck 140 in association with the ready-mixed concrete information. The small block information recording module 458 is a module that records the block number of the small block into which the transported ready-mixed concrete has been poured together with the identification number of the agitator truck 140 in association with the ready-mixed concrete information.

The pouring start time recording module 459 is a module that records the arrival time of the agitator truck 140 as the concrete pouring start time, together with the identification number and block number, in association with the ready-mix concrete information. The unloading end determination module 470 is a module that determines the end of unloading of ready-mix concrete. The pouring end time recording module 471 is a module that records the time that it is determined that the unloading of ready-mix concrete has ended, together with the identification number and block number, in association with the ready-mix concrete information, in association with the concrete pouring end time. These modules 451 to 459, 470 to 471 are read by the CPU 410 into the application execution area 446 of the RAM 440 and executed. The control program 472 is a program for controlling the entire concrete pouring management device 100.

The input/output interface 460 interfaces with input/output devices for input/output data. A display unit 461 and an operation unit 462 are connected to the input/output interface 460. A storage medium 464 may also be connected to the input/output interface 460. A speaker 463 serving as an audio output unit, a microphone (not shown) serving as an audio input unit, or a GPS position determination unit may also be connected. Note that the RAM 440 and storage 450 shown in FIG. 4 do not show programs or data relating to the general-purpose functions of the concrete pouring management device 100 or other feasible functions.

Next, the processing procedure of the concrete pouring management device 100 will be described with reference to the flowchart shown in FIG. 5A. This flowchart is executed by the CPU 410 in FIG. 4 using the RAM 440, and realizes each functional configuration of the concrete pouring management device 100 in FIG. 2.

In step S501, the acquisition unit 201 acquires three-dimensional design information of the structure. In step S503, the small block generation unit 202 divides the three-dimensional design information into pouring blocks of a predetermined size, and generates small blocks by dividing each of the divided pouring blocks into blocks of a predetermined size. In step S505, a block number indicating the pouring order of the concrete is assigned to each of the generated small blocks.

In step S507, the shipment detection unit 204 detects the shipment of ready-mixed concrete by the agitator vehicle 140 that transports ready-mixed concrete manufactured at the manufacturing plant to the construction site 160. The method of shipment detection includes, but is not limited to, a method of receiving a shipping signal from a mobile terminal installed at the manufacturing plant, or a method of detecting shipment from an image captured by an imaging unit such as a camera. In step S509, the shipping time recording unit 205 records the time when the shipment was detected in association with ready-mixed concrete information including information about the ready-mixed concrete.

In step S511, the arrival detection unit 206 detects the arrival of the agitator vehicle 140 at the construction site 160. In step S513, the small block information recording unit 208 records the block number of the small block into which the ready-mix concrete has been poured, together with the identification number, in association with the ready-mix concrete information.

Now, referring to FIG. 5B, the details of the process in step S513 of associating and recording the small block number with ready-mix concrete information and the like will be described. The circled numbers shown in the figure are the identification numbers (or vehicle numbers) of the agitator vehicle 140. Note that the identification number of the agitator vehicle 140 and the vehicle number are associated in advance.

First, we will explain the case where concrete is poured into small blocks A1 to A3. The agitator vehicle 140 with identification number 5 is unloading at the pouring location where the pump vehicle 150 is parked at the construction site 160, between time T1 (13:00) and time T2 (13:10). During the same time period (13:00-13:10), concrete is poured into small block A1, and the pouring start and end times for small block A1 fall within this time period. In this case, the unloading time of agitator vehicle 140 No. 5 overlaps with the time to pour concrete into small block A1, so the concrete transported by agitator vehicle 140 No. 5 is recorded as having been poured into small block A1 and associated with the block number of small block A1. That is, the concrete pouring management device 100 compares the unloading time of the agitator truck 140 with the time when concrete is poured into the small blocks, and records the vehicle number of the agitator truck 140 and the block number of the small block in association with each other depending on whether there is an overlapping time period. In the figure, the white circle with the horizontal bar for small block A1 indicates the start time of pouring concrete, and the black circle indicates the end time of pouring concrete, and the same is true for the other small blocks.

Next, the agitator vehicle 140 with the identification number 8 performs unloading work between 13:10 and 13:20, during which time concrete is poured into small block A2. Therefore, the concrete transported by agitator vehicle 140 with identification number 8 is recorded as having been poured into small block A2 in association with the block number of small block A2.

Similarly, the agitator vehicle 140 with identification number 10 performs unloading work between 13:20 and 13:30, during which time concrete is poured into small block A3. Therefore, the concrete transported by agitator vehicle 140 10 is recorded as having been poured into small block A3 in association with the block number of small block A3. Above, we have explained an example in which concrete transported by one agitator vehicle 140 is poured into one small block.

Next, an example will be described in which concrete transported by one agitator vehicle 140 is poured into multiple small blocks. First, concrete is poured into small block B1 and small block B2 during the time period (13:00-13:10) when agitator vehicle No. 5 140 is unloading. Therefore, concrete transported by agitator vehicle No. 5 140 is recorded as having been poured into small block B1 and small block B2 in association with the block numbers of small block B1 and small block B2.

During the time period when agitator vehicle 140 No. 8 is unloading (13:10-13:20), concrete is continuously poured into small block B2, and concrete is also being poured into small block B3. Therefore, concrete transported by agitator vehicle 140 No. 5 and agitator vehicle 140 No. 8 is being poured into small block B2. Therefore, during the time period when concrete is being poured into small block B2, unloading is being performed by two agitator vehicles 140 (No. 5 and No. 8), so the concrete transported by the two agitator vehicles 140 is recorded as having been poured in association with the block number of small block B2.

In contrast, for small block B3, during the time period when concrete is being poured into small block B3, the concrete is being unloaded by agitator vehicle 140 no. 8. Therefore, the concrete transported by agitator vehicle 140 no. 8 is recorded as having been poured into small block B3 in association with the block number of small block B3.

In addition, concrete is poured into small block B4 during the time period when agitator vehicle 140 No. 8 is unloading (13:10-13:20). Therefore, concrete transported by agitator vehicle 140 No. 8 is poured into small block B4, and this is recorded in association with the block number of small block B4. Furthermore, concrete continues to be poured into small block B4 during the time period when agitator vehicle 140 No. 10 is unloading (13:20-13:30). Therefore, concrete transported by two agitator vehicles 140 (No. 8 and No. 10) is poured into small block B4, and this is recorded in association with the block number of small block B4.

In step S515, the arrival time recording unit 207 records the time when the arrival of the agitator truck 140 is detected as the arrival time of the ready-mixed concrete, together with the identification number of the agitator truck 140, in association with the ready-mixed concrete information. The pouring start time recording unit 209 records the arrival time of the agitator truck 140 as the start time of pouring the concrete, together with the identification number and block number, in association with the ready-mixed concrete information.

In step S517, the unloading completion determination unit 210 determines whether or not the unloading of the ready-mixed concrete has been completed. If it is determined that the unloading has not been completed (N in step S517), the concrete pouring management device 100 continues the determination. If it is determined that the unloading has been completed (YES in step S517), the concrete pouring management device 100 proceeds to the next step. In step S519, the pouring completion time recording unit 211 records the time at which it is determined that the unloading has been completed as the concrete pouring completion time, together with the identification number and block number, in association with the ready-mixed concrete information.

According to this embodiment, it is possible to consistently manage the process from transporting ready-mix concrete to pouring it.

[Second embodiment]
Next, a concrete pouring management device according to a second embodiment of the present invention will be described with reference to Figures 6 to 10. Figure 6 is a diagram for explaining an overview of the operation of a concrete pouring management device 600 according to this embodiment. The concrete pouring management device 600 according to this embodiment differs from the first embodiment in that it extracts ready-mix concrete information about defects found during inspection of a structure after concrete pouring. Other configurations and operations are similar to those of the first embodiment, so the same configurations and operations are denoted by the same reference numerals and detailed explanations thereof are omitted.

For example, after a structure is constructed, inspection work is periodically performed to check for defects such as cracks or damage. If a defect 611 is found in one of the small blocks 610 that make up the structure during this periodic inspection work, the cause of the defect must be identified in order to carry out repairs, etc.

In the concrete pouring management device 600, various information is recorded for each small block, such as the factory where the poured concrete was manufactured, the material mix, and the time elapsed from shipment to completion of pouring. Therefore, when a defect 611 is found in a small block 610 in which concrete has already been poured, the concrete pouring management device 600 identifies the small block 610 in which the defect occurs based on measurement data that measures the distance from a reference position 612 to the defect 611. Then, various information (ready-mixed concrete information) related to the concrete poured in the identified small block 610, which is recorded in association with the identified small block 610, is extracted from a specified database or the like. The person in charge of maintaining the structure can consider maintenance methods based on the extracted ready-mixed concrete information.

Next, the configuration of the concrete pouring management device 600 will be described with reference to FIG. 7. The concrete pouring management device 600 differs from the first embodiment in that it has a measurement data receiving unit, an identifying unit, and an extracting unit. The concrete pouring management device 600 has a measurement data receiving unit 701, an identifying unit 702, and an extracting unit 703.

After concrete is poured for all of the small blocks generated for the structure and the structure is constructed, the measurement data receiving unit 701 inspects the structure and, if a defect is found, receives measurement data that measures the position of the defect found as a distance from a predetermined reference position (reference position 612). The predetermined reference position may be any position on the constructed structure. The measurement data that is received is obtained, for example, by an inspector measuring the distance using a tape measure, distance measuring device, etc.

Furthermore, if the structure is a large-scale structure and it is difficult for an inspector to approach the defective location, an unmanned aerial vehicle (drone) can be used to capture an image of the defective location so that the specified reference position is captured. Then, data can be obtained by estimating the distance from the captured image of the defective location.

The identification unit 702 identifies the position where the defect occurs and the relationship with the small block based on the received measurement data. That is, the identification unit 702 identifies the small block where the defect occurs and identifies the block number of the identified small block. Also, for example, if the defect occurs across multiple small blocks, the identification unit 702 identifies multiple block numbers.

For each small block that has been generated, there is information about its position from a reference position in the 3D design information. For example, an inspection worker can identify which small block the defect is occurring in by measuring the distance from the reference position in the 3D design information for the defect that has occurred. Here, defects include, but are not limited to, weak parts such as cold joints, peeling, exposed internal structure, exposed rebar, and damage such as rust, water leakage, and free lime.

The extraction unit 703 extracts ready-mixed concrete information recorded in the small block information recording unit 208 for the small block in which the defect occurred. In the concrete pouring management device 600, information is recorded for each small block regarding which agitator truck 140 the ready-mixed concrete was transported and poured. Therefore, based on this information, the extraction unit 603 extracts information such as the manufacturing plant and mix of the ready-mixed concrete poured into the small block in which the defect occurred. Then, by using the extracted ready-mixed concrete information, it becomes possible to estimate the cause of the defect.

The hardware configuration of the concrete pouring management device 600 will be described with reference to FIG. 8. The RAM 840 is a random access memory used by the CPU 410 as a work area for temporary storage. The RAM 840 has a storage area reserved for storing data necessary to realize this embodiment. The measurement data 841 is data on the distance from a predetermined reference position measured by an inspector to the position of the defect discovered.

The storage 850 stores a database, various parameters, or the following data or programs required to realize this embodiment. The storage 850 stores a measurement data reception module 851, an identification module 852, and an extraction module 853. The measurement data reception module 851 is a module that receives measurement data that measures the position of a defect discovered by an inspector during an inspection of a structure after the structure is constructed, as a distance from a predetermined reference position. The identification module 852 is a module that identifies a small block in which a defect has occurred based on the received measurement data. The extraction module 853 is a module that extracts ready-mix concrete information recorded for a small block in which a defect has occurred. These modules 851 to 853 are read into the application execution area 446 of the RAM 840 by the CPU 410 and executed.

Next, the processing procedure of the concrete pouring management device 600 will be described with reference to the flowchart shown in FIG. 9. This flowchart is executed by the CPU 410 in FIG. 8 using the RAM 840, and realizes each functional configuration of the concrete pouring management device 600 in FIG. 7.

In step S901, the measurement data receiving unit 701 receives measurement data that measures the position of the defect as a distance from a specified reference position. In step S903, the identification unit 702 identifies the position of the defect based on the received measurement data, and identifies the small block in which the defect occurs from the identified position of the defect. In step S905, the extraction unit 703 extracts ready-mix concrete information recorded by the small block information recording unit 208 for the small block in which the defect occurred.

According to this embodiment, it is possible to consistently manage the process from transporting ready-mix concrete to pouring and maintenance after pouring.

[others]
The concrete pouring management devices 100 and 600 can distinguishably display small blocks that have already been poured, small blocks that are being poured, and small blocks that have not yet been poured, as part of management during concrete pouring. For example, small blocks in which concrete has been poured (already poured small blocks), small blocks in which concrete is being poured (pouring small blocks), and small blocks in which concrete has not yet been poured (unpouring small blocks) are displayed in different colors.

In this way, the concrete pouring management device 100, 600 makes it possible to display each small block in a different color according to the time that has elapsed since the start of concrete pouring. Therefore, in the concrete pouring management device 100, 600, the small block information recording unit 208 also records the progress of each small block from the start of pouring to the end of pouring. For example, it is conceivable that the state of the completed structure will differ between a case in which concrete pouring for a certain small block is completed with plenty of time to spare, and a case in which concrete pouring for another small block is completed within the specified time, but both the start and end times of pouring are just before the specified time.

For example, if there are multiple small blocks adjacent to a certain small block, and concrete pouring cannot be carried out in the adjacent small blocks until the concrete pouring of the small block is completed, if the concrete pouring of the small block is completed right at the designated time, the concrete pouring of the adjacent small blocks will be affected by the concrete pouring of the small block, and the concrete pouring of the adjacent small blocks will be completed right at the designated time, and this effect on the surrounding small blocks may cause defect 611.

Therefore, when concrete is poured into a small block, the small block information recording unit 208 also records information about the condition under which the concrete was poured. In other words, the small block information recording unit 208 records the results displayed in an identifiable manner according to the remaining time until the concrete pouring is completed, which is specified for each small block, in association with information about the ready-mix concrete poured into that small block. This makes it possible to perform more accurate maintenance management, since even if a defect 611 is discovered during a subsequent inspection, information about the condition of the concrete poured into the small block can be considered together with information about the ready-mix concrete.

The present invention has been described above with reference to the embodiments, but the present invention is not limited to the above-described embodiments and can be modified as appropriate. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
