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 100 according to a first embodiment of the present invention will be described with reference to Figures 1A to 5. The concrete pouring management device 100 is a device for managing the transportation and pouring of concrete using image data of slips used when transporting and pouring ready-mixed concrete.

The operation of the concrete pouring management device 100 will be described with reference to Figures 1A and 1B. As shown in Figure 1A, ready-mix concrete manufactured at the manufacturing plant 130 is shipped from the manufacturing plant 130 and transported to the construction site 160. In this case, at the time of shipment from the manufacturing plant 130, an employee of the manufacturing plant 130 or the like fills in the necessary items, including the shipping time of the ready-mix concrete, in the corresponding item fields on a paper slip 120. The employee then hands the slip 120 with the necessary items filled in to the driver of the agitator truck 140, which is a transport vehicle that transports the ready-mix concrete, and the driver takes the slip 120 and departs for the construction site 160.

In this embodiment, when the agitator vehicle 140 departs from the manufacturing plant 130, the driver of the agitator vehicle 140 or an employee of the manufacturing plant 130 captures the slip 120 with a camera 190 mounted on a mobile terminal such as a tablet terminal. Once the image of the slip 120 has been captured, the driver transmits image data 191 of the slip 120 to the concrete pouring management device 100 via wireless communication or wired communication.

The image of the slip 120 at the manufacturing plant 130 may be captured by the driver of the agitator vehicle 140 or an employee of the manufacturing plant 130 using a camera 190 installed on a tablet terminal, or a camera for reading slips installed at the manufacturing plant 130. Alternatively, a camera installed in the concrete pouring management device 100 may be used.

Then, the concrete pouring management device 100 acquires the image data 191 of the slip 120 that was sent. The concrete pouring management device 100 performs OCR (Optical Character Recognition) processing on the acquired image data 191 of the slip 120 to read the contents of the slip 120. The contents read from the slip 120 include, for example, the vehicle number of the agitator truck 140, the load of ready-mixed concrete, and the shipping time of the ready-mixed concrete. Once the reading of the contents is complete, the concrete pouring management device 100 links and records the vehicle number, load, and shipping time read from the slip 120. Once these tasks are complete, the driver of the agitator truck 140 departs for the construction site 160.

Then, when the agitator vehicle 140 arrives at the construction site 160, the worker operates the operation button displayed on the display of at least one mobile terminal 195 such as a tablet terminal distributed to the worker at the construction site 160. The operation button operated by the worker is a start button for recording the start time of unloading the ready-mixed concrete transported from the manufacturing plant 130 to the construction site 160. The worker presses the start button displayed on the display of the mobile terminal 195. The concrete pouring management device 100 records the time when the start button is pressed as the unloading start time, and links it to the vehicle number of the agitator vehicle 140 to manage the transportation and pouring of concrete. Note that the mobile terminals 195 may not be distributed to the workers at the pouring site, but one mobile terminal 195 may be placed for each pump vehicle 150 dispatched to the pouring site. In this case, since there is a one-to-one correspondence between the mobile terminal 195 and the pump vehicle 150, if an identification number for identifying the pump vehicle 150 is stored in advance in the mobile terminal 195, the worker can automatically select the pump vehicle 150 to be unloaded by operating the unloading start button (the identification number of the pump vehicle 150 can be selected).

In this way, the concrete pouring management device 100 performs OCR processing on the paper slips 120 that have been widely used in the past to manage the transportation of ready-mixed concrete when it is shipped from the ready-mixed concrete manufacturing plant 130. Then, when the ready-mixed concrete arrives at the construction site 160, the concrete pouring management device 100 manages pouring at the construction site 160 by the button operation of the worker at the construction site 160.

Next, referring to FIG. 1B, we will explain the operation screen of the start button on the concrete pouring management device 100 when the agitator truck 140 arrives at the construction site 160. When the agitator truck 140 arrives at the construction site 160, for example, a screen 170 is displayed on the display of a mobile terminal 195 held by a worker at the construction site 160. Screen 170 is composed of three screens: a start/end selection screen 171, an unloading start screen 172 (end screen), and a confirmation screen 173.

Then, a start/end selection screen 171 appears on the display of the mobile terminal 195 carried by the worker at the construction site 160, and the worker selects whether the work to be performed is to start unloading or to end unloading. Note that in FIG. 1B, the start of unloading is used as an example for explanation, but even if unloading is to end, the screen operation does not change significantly, only the displayed button changes.

Since the work to be done at the construction site 160 is unloading work, the worker at the construction site 160 presses the start button 174 displayed on the start/end selection screen 171. This transitions the display on screen 170 from the start/end selection screen 171 to an unloading start screen 172. At the bottom of the unloading start screen 172, a list of agitator trucks 140 currently transporting ready-mixed concrete from the manufacturing plant 130 to the construction site 160 is displayed in order of the earliest ready-mixed concrete shipping time.

For example, the ready mixed concrete shipped at "09:30" has a vehicle number (car number) of "037" which is used by the manufacturing plant 130 to identify the agitator vehicle 140 transporting the ready mixed concrete at the first plant. Also, the transported amount (loading amount) of the ready mixed concrete is displayed as "4.5 [ ^m3 ]".

When the agitator truck 140 with the vehicle number "037" that departed from the manufacturing plant 130 at "09:30" arrives at the construction site 160 and begins unloading, the worker at the construction site 160 presses the unloading start button 175. When the unloading start button 175 is pressed, the time the unloading start button 175 is pressed is linked to the vehicle number "037" and recorded as the concrete pouring start time.

In addition, the unloading start button 175 displayed to the right of the vehicle numbers "037" and "844" and the unloading start button displayed to the right of the vehicle number "036" are alternately positioned. In this way, the unloading start button is positioned as shown in the figure on the unloading start screen 172 to make it easier for the worker to operate the buttons (to prevent erroneous operation).

When the unloading start button 175 is pressed, the unloading start screen 172 transitions to display a confirmation screen 173. The confirmation screen 173 is a screen for the worker at the construction site 160 to confirm that the vehicle number of the agitator vehicle 140 selected on the unloading start screen 172 is correct. If the selection is correct, the worker presses the "Unloading start OK" button, and the unloading start time (concrete pouring start time) is recorded. If the selection is incorrect, the worker presses the "Undo" button to return to the unloading start screen 172, and the worker can press the unloading start button for the correct vehicle number again. Even when unloading is complete, the unloading start button 175 is mainly changed to the unloading completion button among the display contents of the unloading start screen 172, and a detailed explanation is omitted.

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 reading unit 202, a first recording unit 203, a second recording unit 204, a third recording unit 205, and a display control unit 206.

The acquisition unit 201 acquires image data 191 of the slip 120, which is used when transporting the ready-mixed concrete manufactured at the ready-mixed concrete manufacturing plant to the concrete construction site 160, by reading the slip 120 using an imaging device at the time of shipment of the ready-mixed concrete. In other words, the concrete pouring management device 100 uses image data 191 of the paper slip 120, which is used when transporting the ready-mixed concrete manufactured at the ready-mixed concrete manufacturing plant 130 to the construction site 160 by the agitator truck 140. Therefore, in order to be able to use the paper slip 120 in the concrete pouring management device 100, the paper slip 120 is read (imaged) using a camera 190 (imaging device) of a mobile terminal carried by an employee of the manufacturing plant 130 or the driver of the agitator truck 140, and the like, to generate image data 191.

In this way, by reading the paper slip 120 with the camera 190 and generating image data 191, the slip 120 can be handled as digital data in the concrete pouring management device 100. The generated image data 191 is transmitted to the concrete pouring management device 100. Here, the concrete pouring management device 100 and a mobile terminal carried by the driver of the agitator vehicle 140 or the like are connected via wireless communication or wired communication.

Then, the acquisition unit 201 acquires image data 191 transmitted from a mobile terminal carried by the driver of the agitator vehicle 140 or the like. The transmitted image data 191 also includes information such as the imaging conditions and imaging time.

The reading unit 202 reads the vehicle number of the agitator truck 140, the load of ready-mixed concrete, and the shipping time of the ready-mixed concrete, which are written on the slip 120, from the image data 191. The reading unit 202 reads the contents of the slip 120 by performing OCR processing on the acquired image data 191. Note that the contents of the slip 120 read by the reading unit 202 are not limited to the vehicle number, load, and shipping time.

The vehicle number of the agitator vehicle 140 is a one to four digit number that is displayed, for example, on the door part on the side of the body of the agitator vehicle 140 or on the front of the body, and is called a door number. Door numbers are displayed in an easily visible position compared to vehicle registration numbers (number plates), making them easy to monitor using surveillance cameras at manufacturing plants 130 and the like, and are therefore widely used. In addition, because they are displayed in an easily visible position, vehicle management for loading ready-mix concrete and identification of waiting vehicles can be easily performed, and the door number is a number that is widely used as the management number of the agitator vehicle 140.

The first recording unit 203 records the read vehicle number, load, and shipping time in association with each other. If the contents of the slip 120 are unclear or the position of the writing is shifted and the reading unit 202 cannot read the shipping time, the first recording unit 203 may perform the following process. That is, the first recording unit 203 records the time when the slip 120 is read by the camera 190 as the shipping time. This makes it possible to manage the transportation time of the ready-mixed concrete (the shipping time required to calculate the transportation time) even if the shipping time is not written in the specified position on the slip 120 or is written in a position shifted from the specified position. This completes a series of processes at the time of shipping the ready-mixed concrete, and management of the transportation time of the ready-mixed concrete begins.

When the agitator truck 140 arrives at the construction site 160, the second recording unit 204 records the time when a worker at the construction site 160 presses a start button displayed on the display of at least one mobile terminal 195 distributed to the construction site 160 to record the start time of unloading the ready-mix concrete, as the concrete pouring start time, and links this to the vehicle number.

In other words, when the ready mixed concrete shipped from the manufacturing plant 130 arrives at the construction site 160 and unloading begins, pouring of the concrete begins not long after. Therefore, the second recording unit 204 records the time when the unloading start button 175 is pressed as the concrete pouring start time. By performing such processing, it is possible to seamlessly manage the completion of the transportation of ready mixed concrete by the agitator truck 140 and the start of concrete pouring. Also, for the worker at the construction site 160, it is possible to manage the completion of the transportation of ready mixed concrete and the start of concrete pouring with a single button operation, so that concrete pouring management can be performed simply and reliably.

The mobile terminal 195 distributed to the construction site 160 may be a terminal carried by a worker at the construction site 160, or may be a terminal attached to the agitator vehicle 140, the construction site 160, or a pump vehicle 150 assigned to the construction site 160. In addition, there may be multiple mobile terminals 195 at the construction site 160.

The third recording unit 205 records the time when the worker at the construction site 160 presses the end button shown on the display to record the end time of unloading the ready-mix concrete, as the end time of pouring the concrete, and links it to the vehicle number.

In other words, when the agitator truck 140 arrives at the construction site 160, the storage drum of the agitator truck 140 for fresh concrete is connected to the pump truck 150 by a chute, and fresh concrete is poured from the agitator truck 140 into the pump truck 150. Then, when the fresh concrete transported by the agitator truck 140 is gone from the storage drum, the pouring of fresh concrete into the pump truck 150 ends. In other words, at this stage, there is no more fresh concrete to be supplied to the pouring location, and pouring of the concrete transported by the agitator truck 140 ends.

Therefore, the third recording unit 205 records the time when the worker at the construction site 160 presses the unloading end button as the time when the concrete pouring ends, together with the vehicle number of the agitator vehicle 140. This makes it possible to manage the end of unloading of ready-mix concrete and the completion of pouring of concrete with a single button operation, and allows the worker at the construction site 160 to easily and reliably manage the pouring of concrete.

The display control unit 206 displays at least one of the recorded vehicle number, load, shipping time, concrete pouring start time, and concrete pouring end time on the display. The display control unit 206 displays various recorded data on the display of a mobile terminal 195 such as a tablet terminal carried by a worker at the construction site 160. This allows the worker at the construction site 160 to check the progress of the work and the degree to which the plan has been achieved by comparing the concrete pouring work at the construction site 160 with the recorded data.

The concrete pouring management device 100 may also have a notification unit that issues an alert when the transportation time of the ready-mixed concrete calculated from the recorded shipping time and arrival time exceeds the transportation reference time. By issuing this alert, it is possible to warn of the approach of the management time and to encourage workers and the like to be careful. Here, the transportation reference time is the time by which the agitator vehicle 140 must arrive at the construction site 160, which is set a predetermined time before the transportation management time. In addition, the transportation management time is the time allowed for ready-mixed concrete manufactured at the manufacturing plant 130 to be transported to the construction site 160, and is the time beyond which ready-mixed concrete transported to the construction site 160 cannot be poured. In other words, the transportation management time is a standard time for maintaining the quality of concrete, as determined by the Japanese Industrial Standards (JIS) and the Standard Specifications for Concrete. If the transportation time exceeds the transportation management time, the concrete must be returned without being unloaded. The standard transportation time is set to be shorter than the transportation and management time, but this is set taking into account the time required for pouring concrete. In other words, the standard transportation time is calculated so that if the ready-mix concrete is transported by this time, the time until concrete pouring is completed falls within the transportation and management time. The standard transportation time is set, for example, 10 to 15 minutes shorter than the transportation and management time.

Furthermore, the concrete pouring management device 100 may have a notification unit that issues an alert when the pouring end time (unloading end time) estimated from the recorded arrival time exceeds the pouring reference time. In other words, when this alert is issued, the transported ready-mixed concrete must be returned to the manufacturing plant 130. Here, the pouring reference time is the time by which the transported ready-mixed concrete must be poured, which is set a predetermined time before the pouring management time. The predetermined time is a time determined based on the time required to pour the concrete. In addition, the pouring management time is the time allowed for the ready-mixed concrete manufactured at the manufacturing plant 130 to be poured at the construction site 160, and if pouring is completed beyond this time, the quality of the concrete after hardening cannot be maintained. In other words, the pouring management time is a standard time for maintaining the quality of concrete after pouring, as determined by the Japanese Industrial Standards and the Concrete Standard Specifications. The standard pouring time is set to be shorter than the pouring control time, but is set to ensure the safety of the poured concrete. The standard pouring time is, for example, the pouring control time minus the estimated time required for pouring.

Next, referring to FIG. 3, an example of the image data table 301 held by the concrete pouring management device 100 will be described. The image data table 301 stores image data information 312, read content data 313, unloading start time 314, and unloading end time 315 in association with an image data ID (Identifier) 311. The image data ID 311 is an identifier for identifying the image data 191 of the slip 120 captured by the camera 190. The image data information 312 is information about the imaging conditions and imaging time of the slip 120. The read content data 313 is data about the contents read from the image data 191 of the slip 120 by OCR processing, and includes the vehicle number, shipping time, and loading amount. The unloading start time 314 is the time when the worker at the construction site 160 presses the unloading start button 175. The unloading end time 315 is the time when the worker at the construction site 160 presses the unloading end button.

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 transmitted or received data in an area of the RAM (Random Access Memory) 440. It is also preferable to provide a DMAC (Direct Memory Access Controller) (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 or the DMAC.

RAM 440 is a random access memory used by CPU 410 as a temporary storage work area. RAM 440 has a storage area reserved for storing data necessary for implementing this embodiment. Invoice image data 441 is image data of invoice 120 captured by imaging equipment, and is image data of invoice 120 captured at the time of shipment from manufacturing factory 130. Image data information 442 is information including the imaging conditions and imaging time when invoice 120 was captured. Read data 443 is data related to the contents of invoice 120 read from image data 191. Start and end time data 444 is data related to the time when the worker at construction site 160 pressed unloading start button 175 and unloading end button.

Transmitted and received data 445 is data transmitted and received via the network interface 430. In addition, the RAM 440 has an application execution area 446 for executing various application modules.

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

The storage 450 further stores an acquisition module 451, a reading module 452, a first recording module 453, a second recording module 454, a third recording module 455, and a display control module 456. The acquisition module 451 is a module that acquires image data 191 of the slip 120. The reading module 452 is a module that reads the vehicle number, the load, and the shipping time written on the slip 120 from the image data 191. The first recording module 453 is a module that links and records the read vehicle number, the load, and the shipping time. The second recording module 454 is a module that links and records the time when the worker at the construction site 160 presses the unloading start button 175 as the concrete pouring start time and links it to the vehicle number. The third recording module 455 is a module that links and records the time when the worker at the construction site 160 presses the unloading end button as the concrete pouring end time and links it to the vehicle number. The display control module 456 is a module that displays the vehicle number, load, shipping time, and arrival time on the display of the mobile terminal. These modules 451 to 456 are read into the application execution area 446 of the RAM 440 by the CPU 410 and executed. The control program 457 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. 5. 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 image data 191 of the slip 120 that was generated by scanning using the camera 190 at the time of shipment from the manufacturing plant 130. In step S503, the reading unit 202 reads from the image data 191 the vehicle number of the agitator vehicle 140, the load of ready-mixed concrete, and the shipping time of the ready-mixed concrete, which are written on the slip 120.

In step S505, the first recording unit 203 determines whether the shipping time can be read. If it is determined that the shipping time can be read (YES in step S505), the first recording unit 203 proceeds to step S507. In step S507, the first recording unit 203 records the read vehicle number, load, and shipping time in association with each other.

If it is determined that the shipping time cannot be read (NO in step S505), the first recording unit 203 proceeds to step S509. In step S509, the first recording unit 203 records the time when the camera 190 reads the slip 120 as the shipping time of the ready-mix concrete, linking it to the vehicle number, etc.

In step S511, the second recording unit 204 records the time when the worker at the construction site 160 presses the unloading start button 175 as the concrete pouring start time, and links it to the vehicle number of the agitator truck 140. In step S513, the third recording unit 205 records the time when the worker at the construction site 160 presses the unloading end button as the concrete pouring end time, and links it to the vehicle number of the agitator truck 140.

According to this embodiment, the details entered on the delivery slip when the concrete was shipped are used as is, so there is no room for human error such as entry or input errors, and concrete pouring can be managed quickly and accurately. Also, at the pouring site, the data recorded at the time of shipment is used as is, so there is no room for human error, just as there was at the time of shipment. Furthermore, the read details are recorded linked to the vehicle number of the agitator vehicle, so the pouring destination and manufacturer of the concrete transported by the agitator vehicle can be managed centrally. In addition, the transport time of the concrete and the pouring time of the concrete can be easily managed.

[Second embodiment]
Next, a concrete pouring management device according to a second embodiment of the present invention will be described with reference to Figures 6A to 9. Figure 6A is a block diagram for explaining the configuration 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 has a reception unit 601 and a fourth recording unit 602. Since the other configurations and operations are the same as those of the first embodiment, the same configurations and operations are denoted by the same reference numerals and detailed description thereof will be omitted.

The concrete pouring management device 600 has a reception unit 601 and a fourth recording unit 602. The reception unit 601 receives an identification number selected by a worker at the construction site 160 using at least one mobile terminal 195 to identify at least one pump vehicle 150 arranged at the construction site 160 in order to supply ready-mixed concrete to a specified pouring location. In other words, when the agitator vehicle 140 arrives at the construction site 160, it must determine which pump vehicle 150 will deliver the transported ready-mixed concrete.

In this case, first, a guide at the construction site 160 guides the agitator vehicle 140 that has arrived at the construction site 160 to the pouring location where the pump vehicle 150 is parked within the construction site 160. That is, the guide instructs the driver of the agitator vehicle 140 which pump vehicle 150 to head to if there are multiple pump vehicles 150. Then, the driver of the agitator vehicle 140 moves the agitator vehicle 140 to the specified pump vehicle 150 according to the instruction.

Next, the worker at the construction site 160, the operator of the pump vehicle 150, the driver of the agitator vehicle 140, etc., use a mobile terminal 195 distributed to the construction site 160 (concrete pouring location) or a mobile terminal 195 installed in the pump vehicle 150 to extract the identification number of the pump vehicle 150 that is pre-linked to the mobile terminal 195. Then, the reception unit 601 receives the identification number. Then, the reception unit 601 receives the selected identification number.

The fourth recording unit 602 records information on the small blocks into which the ready-mix concrete has been poured, in the three-dimensional design information of the structure, which is divided into large blocks of a predetermined size and each of the divided large blocks is divided into small blocks of a predetermined size, in association with the identification number of the pump car 150 and the vehicle number of the agitator car 140 received by the reception unit 601. By linking and recording the identification number of the pump car 150 and the vehicle number of the agitator car in this way, it is possible to track which small block (pouring location) the ready-mix concrete transported by the agitator car 140 has been poured into, even after pouring is completed. Information on which agitator car 140 with which vehicle number unloaded concrete into which pump car 150, information on the small blocks into which the unloaded concrete was poured, information on the transportation time, information on the pouring time, and the like are recorded in the form of a form such as that shown in FIG. 6B. In addition to the vehicle number of the agitator vehicle 140, identification numbers such as license plate numbers may also be recorded on the form.

When pouring concrete into a structure, unhardened concrete is transported using an agitator vehicle 140, and the unhardened concrete is poured, for example, into the formwork assembled in the construction area for one day. Then, before the previously poured concrete hardens, the next concrete is poured and compacted using a vibrator or the like, and the two concretes poured one after the other are integrated. By repeating this process from pouring to integration, the pouring of concrete into the construction area is completed. After the concrete has been poured, it is left to cure for a certain period of time to harden, and the assembled formwork is removed.

In this case, when pouring concrete into a structure in sequence, it is necessary to use a vibrator or similar device to integrate the overlapping concrete before the previously poured concrete hardens. If the time it takes to pour the concrete exceeds the controlled time, cold joints may occur in the overlapping concrete, causing it to become weak. For this reason, when pouring concrete into a structure, it is important to manage the time from mixing the materials, the order in which the concrete is poured, and the time it takes to pour the concrete.

When the size of the concrete construction area becomes large, a large amount of concrete is required, and the number of agitator trucks 140 required to transport the concrete increases. Furthermore, in order to pour concrete for a large-scale structure, the structure must be divided into multiple layers depending on the amount of concrete that the agitator trucks 140 can transport, and the concrete must be poured in an orderly manner, which tends to increase the number of concrete layers. As a result, there are more pouring joints, and in order to prevent weak parts such as cold joints from occurring, it is necessary to plan the pouring sequence and pouring layer thicknesses, taking into account the time it takes to pour the concrete.

The pouring plan is created using three-dimensional design information, which includes three-dimensional data of the structure designed using, for example, three-dimensional CAD (Computer-Aided Design). The three-dimensional design information also includes information such as the construction area and construction period. The three-dimensional design information is a construction area set according to the amount of concrete that can be poured in a specified period of time, and is divided into multiple large blocks. In other words, the structure includes multiple large blocks. The multiple large blocks are then divided into several small blocks according to the amount that the agitator vehicle 140 can carry. In this way, the three-dimensional design information has division data that divides the structure into multiple small blocks, and the concrete is poured in small block units.

Next, referring to FIG. 7, an example of an image data table 701 held by the concrete pouring management device 600 will be described. The image data table 701 stores an identification number 711 in association with an image data ID 311. The identification number 711 is an identifier for identifying the pump vehicle 150 to which the ready-mix concrete transported by the agitator vehicle 140 is to be supplied.

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. An area is reserved in the RAM 840 for storing data necessary for implementing this embodiment. The identification number data 841 is data related to an identifier for identifying the pump vehicle 150.

Storage 850 stores a database, various parameters, or the following data or programs required to realize this embodiment. Storage 850 stores image data table 701. Image data table 701 is a table that manages the relationship between image data ID 311 and identification number 711, etc., shown in FIG. 7.

The storage 850 further stores a reception module 851 and a fourth recording module 852. The reception module 851 is a module that receives an identifier for identifying the pump vehicle 150 selected by the worker at the construction site 160. The fourth recording module 852 is a module that links and records the identification number of the pump vehicle 150 and the vehicle number of the agitator vehicle 140. These modules 851 to 852 are read by the CPU 410 into the application execution area 446 of the RAM 840 and executed. The control program 457 is a program for controlling the entire concrete pouring management device 600.

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. 6.

In step S901, the reception unit 601 receives an identification number for identifying at least one pump vehicle 150 deployed at the construction site 160. The identification number is a number for identifying the pump vehicle 150 selected by a worker at the construction site 160. In step S903, the fourth recording unit 602 links the received identification number with the vehicle number of the agitator vehicle 140 and records them.

According to this embodiment, the vehicle number of the agitator truck and the identification number of the pump truck are linked and recorded, so all information related to concrete can be managed by linking it to small blocks, and it is possible to track the pouring location at which ready-mixed concrete transported from the manufacturing plant was poured, even after pouring is complete.
