EMBODIMENT OF THE INVENTION Below, the form for implementing this invention will be exemplarily described in detail with reference to drawings. However, the configuration, numerical values, process flow, functional elements, etc. described in the following embodiments are merely examples, and modifications and changes may be made freely, and the technical scope of the present invention is limited to the following description. It is not intended to do so.

[First embodiment]
A concrete placement management device 100 as a first embodiment of the present invention will be explained using FIGS. 1A to 5. The concrete placement management device 100 is a device for managing the transportation and placement of concrete using image data of slips used when transporting and placing fresh concrete.

An overview of the operation of the concrete placement management device 100 will be described with reference to FIGS. 1A and 1B. As shown in FIG. 1A, ready-mixed concrete manufactured at manufacturing factory 130 is shipped from manufacturing factory 130 and transported to construction site 160. In this case, at the time of shipment from the manufacturing factory 130, an employee of the manufacturing factory 130 fills in necessary items, including the shipping time of ready-mixed concrete, on the paper slip 120 in each corresponding item column. The employee then hands the slip 120 with the necessary items filled in to the driver of the agitator vehicle 140, which is a transport vehicle for transporting the ready-mixed concrete, and the driver takes the slip 120 and leaves for the construction site 160. do.

In this embodiment, when the agitator car 140 leaves the manufacturing factory 130, the driver of the agitator car 140, the employees of the manufacturing factory 130, etc. use the camera 190 installed on a mobile terminal such as a tablet terminal. The slip 120 is imaged. When the image capturing of the slip 120 is completed, the driver or the like transmits the image data 191 of the slip 120 to the concrete placement management device 100 via wireless communication or wired communication.

Note that the slip 120 at the manufacturing plant 130 can be imaged by the driver of the agitator vehicle 140, an employee of the manufacturing plant 130, or the like using a camera 190 installed on a tablet terminal. A standard camera may also be used. Alternatively, a camera provided in the concrete placement management device 100 may be used.

The concrete placement management device 100 then acquires the image data 191 of the sent slip 120. The concrete placement management device 100 performs OCR (Optical Character Recognition) processing on the image data 191 of the acquired slip 120 to read the written contents of the slip 120. The written contents read from the slip 120 include, for example, the vehicle number of the agitator vehicle 140, the loading amount of ready-mixed concrete, and the shipping time of the ready-mixed concrete. Once the written content has been read, the concrete placement management device 100 records the vehicle number, loading amount, and shipping time read from the slip 120 in association with each other. Once these tasks are completed, the driver of the agitator vehicle 140 leaves for the construction site 160.

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. do. 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 factory 130 to the construction site 160. The worker presses the start button displayed on the display of the mobile terminal 195. The concrete placement management device 100 records the press time of the start button as the unloading start time in association with the vehicle number of the agitator vehicle 140, and manages the transportation and placement of concrete. Note that instead of distributing the mobile terminals 195 to workers at the pouring site, one mobile terminal 195 may be arranged for each pump truck 150 that is dispatched to the pouring site. In this case, the mobile terminal 195 and the pump truck 150 will have a one-to-one correspondence, so if the mobile terminal 195 has an identification number for identifying the pump truck 150 in advance, the worker can unload the cargo. By operating the start button, the pump truck 150 to be unloaded can be automatically selected (the identification number of the pump truck 150 can be selected).

As described above, in the concrete placement management device 100, when shipping the ready-mixed concrete from the manufacturing factory 130, the paper slip 120, which has been widely used in the past, is subjected to OCR processing to manage the transportation of the ready-mixed concrete. Then, when the ready-mixed concrete arrives at the construction site 160, the concrete placement management device 100 performs pouring management at the construction site 160 by a button operation by a worker at the construction site 160.

Next, with reference to FIG. 1B, the operation screen of the start button in the concrete placement management device 100 when the agitator vehicle 140 arrives at the construction site 160 will be described. When the agitator vehicle 140 arrives at the construction site 160, a screen 170 is displayed on the display of a mobile terminal 195 owned by a worker at the construction site 160, for example. The 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 is displayed on the display of the mobile terminal 195 owned by the worker at the construction site 160, and the worker can decide whether the work to be performed is to start unloading or end unloading. Select. In addition, in FIG. 1B, explanation will be given using the start of unloading as an example, but even when unloading ends, the screen operation does not differ significantly, only the displayed button changes.

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

For example, for ready-mixed concrete shipped at "09:30", the manufacturing factory 130 at the first plant has the vehicle number (vehicle number) for identifying the agitator vehicle 140 transporting the concrete as "037". ”. Further, it is displayed that the transport amount (loading amount) of the ready-mixed concrete is "4.5 [m ³ ]".

When the agitator vehicle 140 with vehicle number "037" that left the manufacturing factory 130 at "09:30" arrives at the construction site 160 and starts unloading, the worker at the construction site 160 starts unloading. Press button 175. When the unloading start button 175 is pressed, the time when the unloading start button 175 is pressed is recorded in association with the car number "037" as the concrete placement start time.

Additionally, the display positions of the unloading start button 175 displayed on the right side of car numbers "037" and "844" and the unloading start button displayed on the right side of car number "036" are alternately arranged. has been done. In this way, on the unloading start screen 172, the unloading start buttons are arranged as shown in the figure in order to make it easier for the operator to operate the buttons (to prevent erroneous operations).

Note that when the unloading start button 175 is pressed, the unloading start screen 172 changes and a confirmation screen 173 is displayed. The confirmation screen 173 is a screen for allowing the worker at the construction site 160 to confirm whether the vehicle number of the agitator vehicle 140 selected on the unloading start screen 172 is correct. If the selection is correct, the operator presses the "OK to start unloading" button, and the unloading start time (casting start time) is recorded. If the selection is incorrect, the operator can press the "Undo" button to return to the unloading start screen 172, so the operator can press the unloading start button for the correct vehicle number again. Note that even in the case of the end of unloading, the unloading start button 175 among the displayed contents of the unloading start screen 172 is changed to the unloading end button and is therefore displayed, so a detailed explanation will be omitted.

Next, with reference to FIG. 2, the configuration of the concrete placement management device 100 will be described. The concrete placement management device 100 includes an acquisition section 201, a reading section 202, a first recording section 203, a second recording section 204, a third recording section 205, and a display control section 206.

The acquisition unit 201 reads the slip 120 used when transporting the ready-mixed concrete produced at the ready-mixed concrete manufacturing factory to the concrete construction site 160 using an imaging device at the time of shipping the ready-mixed concrete, and generates a slip. 120 image data 191 is acquired. That is, the concrete placement management device 100 uses the image data 191 of the paper slip 120 used when transporting the ready-mixed concrete manufactured at the ready-mixed concrete manufacturing factory 130 to the construction site 160 by the agitator vehicle 140. do. Therefore, in order to be able to use the paper slip 120 in the concrete placement management device 100, a camera 190 (imaging device) of a mobile terminal owned by an employee of the manufacturing plant 130, a driver of the agitator vehicle 140, etc. is used to read (image) the paper slip 120 and generate image data 191.

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

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

The reading unit 202 reads the vehicle number of the agitator vehicle 140, the loading amount of ready-mixed concrete, and the shipping time of the ready-mixed concrete written on the slip 120 from the image data 191. The reading unit 202 reads the written 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, loading amount, and shipping time.

Here, the vehicle number of the agitator vehicle 140 is, for example, a 1- to 4-digit number displayed on the side door or the front of the vehicle body of the agitator vehicle 140, and is called a door number. It's a number. Since the door number is displayed in a position that is easier to see than the vehicle registration number (license plate), it is easier to monitor using a surveillance camera in the manufacturing factory 130 and the like, so it is widely used. Furthermore, since it is displayed in an easily visible position, it is easy to manage vehicles for loading ready-mixed concrete and to keep track of waiting vehicles.The door number is a number that is widely used as a management number for the agitator vehicle 140.

The first recording unit 203 records the read vehicle number, loading amount, and shipping time in association with each other. Note that if the shipping time cannot be read by the reading unit 202 because the written content of the slip 120 is unclear or the written position is shifted, the first recording unit 203 may perform the following processing. good. That is, the first recording unit 203 records the time when the slip 120 is read by the camera 190 as the shipping time. As a result, even if the shipping time is not written in the predetermined position on the slip 120 or is written in a position shifted from the predetermined position, the transportation time of the ready-mixed concrete (transportation time calculation) (Shipping time required for shipping) can be managed. With the above steps, a series of processes at the time of shipping the ready-mixed concrete are completed, and management of the transportation time of the ready-mixed concrete is started.

The second recording unit 204 records the unloading start time of ready-mixed concrete displayed on the display of at least one mobile terminal 195 distributed to the construction site 160 when the agitator vehicle 140 arrives at the construction site 160. The time at which the worker at the construction site 160 presses the start button is recorded as the concrete placement start time in association with the vehicle number.

In other words, when the ready-mixed concrete shipped from the manufacturing factory 130 arrives at the construction site 160 and unloading is started, concrete pouring begins shortly after. Therefore, the second recording unit 204 records the time when the unloading start button 175 is pressed as the concrete placement start time. By performing such processing, it is possible to seamlessly manage the completion of transportation of fresh concrete by the agitator vehicle 140 and the start of concrete pouring. Additionally, workers at the construction site 160 can manage the completion of fresh concrete transport and the start of concrete pouring with a single button operation, allowing them to manage concrete pouring easily and reliably. It can be performed.

Note that even if the mobile terminal 195 distributed to the construction site 160 is owned by a worker at the construction site 160, it may be used in the agitator vehicle 140, the construction site 160, the pump truck 150 distributed to the construction site 160, etc. It may be an installed terminal. Further, a plurality of mobile terminals 195 may exist at the construction site 160.

The third recording unit 205 sets the time when the worker at the construction site 160 presses the end button displayed on the display for recording the time when unloading of ready-mixed concrete is finished, as the concrete placement end time, and the vehicle number. Record it by linking it to.

That is, when the agitator car 140 arrives at the construction site 160, the fresh concrete storage drum of the agitator car 140 is connected to the pump car 150 through a chute, and the fresh concrete is poured from the agitator car 140 to the pump car 150. When the ready-mixed concrete transported by the agitator car 140 disappears from the storage drum, pouring of the ready-mixed concrete into the pump car 150 ends. That is, at this stage, there is no more fresh concrete to be supplied to the pouring location, so the pouring of concrete transported by the agitator vehicle 140 is completed.

Therefore, the third recording unit 205 records the time when the worker at the construction site 160 presses the unloading end button, together with the vehicle number of the agitator vehicle 140, as the time when concrete placement ends. With this, it is possible to manage the completion of unloading of fresh concrete and the completion of concrete pouring with a single button operation, and workers at the construction site 160 can easily and reliably manage concrete pouring. be able to.

The display control unit 206 causes the display to display at least one of the recorded vehicle number, loading amount, shipping time, pouring start time, and pouring end time. The display control unit 206 displays various data recorded on the display of a mobile terminal 195 such as a tablet terminal owned by a worker at the construction site 160. Thereby, the worker at the construction site 160 can check the progress of the work, the degree of achievement of the plan, etc. while comparing the pouring work at the construction site 160 with the recorded data.

Further, the concrete placement management device 100 may include a notification unit that notifies an alert when the transportation time of ready-mixed concrete calculated from the recorded shipping time and arrival time exceeds the transportation reference time. . By reporting this alert, it is possible to warn that the management time is approaching and to urge workers and the like to be careful. Here, the transportation reference time is a time, which is set a predetermined time before the transportation management time, by which the agitator vehicle 140 must arrive at the construction site 160. Further, the transportation management time is the time allowed until the ready-mixed concrete manufactured at the manufacturing factory 130 is transported to the construction site 160, and if the ready-mixed concrete that has been transported to the construction site 160 is poured beyond this time. This is the time when you will no longer be able to do anything. That is, the transportation control time is a time defined by Japanese Industrial Standards (JIS), concrete standard specifications, etc., and is one of the standards for maintaining the quality of concrete. If the transportation time exceeds the transportation control time, the concrete must be returned without being unloaded. The transportation reference time is set to be shorter than the transportation management time, but this time is set in consideration of the time required for pouring concrete. That is, the transportation reference time is a time calculated such that if the ready-mixed concrete is transported by this time, the time until the concrete placement is completed will be within the transportation management time. The transportation reference time is, for example, a time set to be 10 to 15 minutes shorter than the transportation management time.

Furthermore, the concrete placement management device 100 may include a notification unit that issues an alert when the placing end time (unloading end time) estimated from the recorded arrival time exceeds the standard placing time. good. That is, when this alert is reported, the transported ready-mixed concrete must be returned to the manufacturing factory 130. Here, the pouring reference time is a time, which is set a predetermined time before the pouring management time, by which pouring of the transported ready-mixed concrete must be completed. The predetermined time is a time determined based on the time required for pouring concrete. In addition, the pouring control time is the time allowed for ready-mixed concrete manufactured at the manufacturing factory 130 to finish pouring at the construction site 160, and if the pouring is completed beyond this time, the hardened concrete will This is the time when quality cannot be maintained. That is, the pouring control time is a time defined by the Japanese Industrial Standards, the Standard Specification for Concrete, etc., and is one of the standards for maintaining the quality of concrete after pouring. The pouring reference time is set as a shorter time than the pouring control time, but is set to ensure the safety of poured concrete. The driving reference time is, for example, the time obtained by subtracting the estimated time required for driving from the driving management time.

Next, with reference to FIG. 3, an example of the image data table 301 included in the concrete placement 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 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 regarding the imaging conditions of the slip 120, the imaging time, and the like. The read content data 313 is data about the content read from the image data 191 of the slip 120 by OCR processing, and includes the vehicle number, shipping time, loading amount, and the like. 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 placement management device 100 will be described with reference to FIG. 4. A CPU (Central Processing Unit) 410 is a processor for arithmetic control, and realizes each functional configuration of the concrete placement management device 100 shown in FIG. 2 by executing a program. The CPU 410 has multiple processors and may execute different programs, modules, tasks, threads, etc. in parallel. ROM (Read Only Memory) 420 stores fixed data such as initial data and programs, and other programs. Further, the network interface 430 communicates with other devices via a network. Note that the number of CPUs 410 is not limited to one, and may be a plurality of CPUs or may include a GPU (Graphics Processing Unit) for image processing. Further, it is preferable that the network interface 430 has a CPU independent of the CPU 410 and writes or reads transmitted and received data in a RAM (Random Access Memory) 440 area. Further, it is desirable to provide a DMAC (Direct Memory Access Controller) that transfers data between the RAM 440 and the storage 450 (not shown). Further, the CPU 410 recognizes that data has been received or transferred to the RAM 440 and processes the data. Further, the CPU 410 prepares the processing results in the RAM 440 and leaves subsequent transmission or transfer to the network interface 430 or DMAC.

The RAM 440 is a random access memory used by the CPU 410 as a temporary storage work area. A storage area is secured in the RAM 440 to store data necessary for realizing this embodiment. The slip image data 441 is image data of the slip 120 captured by an imaging device, and is image data of the slip 120 captured at the time of shipment from the manufacturing factory 130. The image data information 442 is information including the imaging conditions and imaging time when the slip 120 was imaged. The read data 443 is data related to the written contents of the slip 120 read from the image data 191. The start/end time data 444 is data related to the time when the worker at the construction site 160 presses the unloading start button 175 and the unloading end button.

Transmission/reception data 445 is data transmitted/received via network interface 430. The RAM 440 also has an application execution area 446 for executing various application modules.

The storage 450 stores a database, various parameters, and the following data or programs necessary for realizing this embodiment. Storage 450 stores image data table 301. The image data table 301 is a table that manages the relationship between the image data ID 311, the image data information 312, etc. shown in FIG.

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 the image data 191 of the slip 120. The reading module 452 is a module that reads the vehicle number, loading amount, and shipping time written on the slip 120 from the image data 191. The first recording module 453 is a module that records the read vehicle number, loading amount, and shipping time in association with each other. The second recording module 454 is a module that records the time when the worker at the construction site 160 presses the unloading start button 175 as the concrete placement start time in association with the vehicle number. The third recording module 455 is a module that records the time when the worker at the construction site 160 presses the unloading end button as the concrete placement end time in association with the vehicle number. The display control module 456 is a module that displays the vehicle number, loading amount, 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 placement management device 100.

The input/output interface 460 interfaces input/output data with input/output equipment. A display section 461 and an operation section 462 are connected to the input/output interface 460. Further, a storage medium 464 may be further connected to the input/output interface 460. Furthermore, a speaker 463 as an audio output section, a microphone (not shown) as an audio input section, or a GPS position determination section may be connected. Note that the RAM 440 and storage 450 shown in FIG. 4 do not show programs or data related to general-purpose functions or other realizable functions that the concrete placement management device 100 has.

Next, the processing procedure of the concrete placement management device 100 will be explained with reference to the flowchart shown in FIG. This flowchart is executed by the CPU 410 in FIG. 4 using the RAM 440 to realize each functional configuration of the concrete placement management device 100 in FIG. 2.

In step S<b>501 , the acquisition unit 201 acquires image data 191 of the slip 120 that was read and generated using the camera 190 at the time of shipment from the manufacturing factory 130 . In step S503, the reading unit 202 reads the vehicle number of the agitator vehicle 140, the loading amount of ready-mixed concrete, and the shipping time of the ready-mixed concrete written on the slip 120 from the image data 191.

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, loading amount, 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 slip 120 is read by the camera 190, as the ready-mixed concrete shipping time, in association with the vehicle number or the like.

According to this embodiment, since the contents entered on the slip at the time of concrete shipment are used as is, there is no room for human errors such as entry errors and input errors, and concrete placement is managed quickly and accurately. can do. Furthermore, at the pouring site, the data recorded at the time of shipment is used as is, so there is no room for human error to occur, just as there is at the time of shipment. Furthermore, since the read information is recorded in association with the vehicle number of the agitator vehicle, it is possible to centrally manage the destination and manufacturer of concrete transported by the agitator vehicle. Furthermore, the concrete transport time and concrete placement time can be easily managed.

[Second embodiment]
Next, a concrete placement management device according to a second embodiment of the present invention will be described using FIGS. 6A to 9. FIG. 6A is a block diagram for explaining the configuration of a concrete placement management device 600 according to this embodiment. The concrete placement management device 600 according to this embodiment differs from the first embodiment in that it includes a reception section 601 and a fourth recording section 602. Since the other configurations and operations are the same as those in the first embodiment, the same configurations and operations will be denoted by the same reference numerals and detailed description thereof will be omitted.

The concrete placement management device 600 has a reception section 601 and a fourth recording section 602. The reception unit 601 receives an identification number for a worker at the construction site 160 to identify at least one pump truck 150 placed at the construction site 160 in order to supply ready-mixed concrete to a predetermined pouring location. At least one mobile terminal 195 is used to accept the selected identification number. That is, when the agitator vehicle 140 arrives at the construction site 160, it is necessary to determine the pump vehicle 150 to which the transported ready-mixed concrete will be delivered.

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 a pouring location within the construction site 160 where the pump vehicle 150 is parked. That is, the guide instructs the driver of the agitator car 140 which pump car 150 to go to if there are a plurality of pump cars 150. Then, the driver of the agitator car 140 moves the agitator car 140 to the designated pump car 150 in accordance with the instruction.

Next, the workers at the construction site 160, the operator of the pump truck 150, the driver of the agitator truck 140, etc., use the mobile terminal 195 distributed at the construction site 160 (place of pouring) or the mobile terminal installed in the pump truck 150. 195, etc., to extract the identification number of the pump truck 150 that is linked to the mobile terminal 195 in advance. Then, the reception unit 601 receives the identification number. Then, the receiving unit 601 receives the selected identification number.

A fourth recording unit 602 stores three-dimensional design information of a structure, divides the three-dimensional design information into large blocks of a predetermined size, and converts each of the divided large blocks into small blocks of a predetermined size. In the three-dimensional design information having the divided division data, information on the small block in which the ready-mixed concrete is placed is linked to the identification number of the pump truck 150 received by the reception unit 601 and the vehicle number of the agitator truck 140. and record it. In this way, by linking and recording the identification number of the pump truck 150 and the vehicle number of the agitator truck, it is possible to determine which small block (place of pouring) the fresh concrete transported by the agitator truck 140 will be poured into. This makes it possible to track what has been done even after the pouring is completed. Then, the agitator car 140 with which vehicle number unloads concrete to which pump car 150, information on the small block into which the unloaded concrete was poured, information on transportation time, information on pouring time, etc. For example, it is recorded in the form of a form as shown in FIG. 6B. In addition to the vehicle number of the agitator vehicle 140, an identification number such as a license plate number may also be recorded in the form.

When pouring concrete for a structure, unhardened concrete is transported by an agitator vehicle 140, and, for example, the unhardened concrete is successively poured into formwork assembled in a construction area on one day. Then, before the previously poured concrete hardens, the next concrete is poured, and the concrete is compacted using a vibrator, etc., and both the poured concrete and the piled concrete are integrated. By repeating this work from pouring to integration, pouring of concrete into the construction area is completed. After the concrete is poured, it is cured for a certain period of time to harden, and the assembled formwork is removed from the mold.

In this case, when pouring concrete into a structure one after another, it is necessary to use a vibrator or the like to integrate the poured concrete and the piled concrete before the previously poured concrete hardens. At this time, if the concrete stacking time exceeds the control time, cold joints may occur in the concrete stacking area, which may become a weak part. Therefore, when pouring concrete for structures, it is important to manage the time from mixing the materials, the order of concrete pouring, and the time required to pour the concrete.

Here, as the scale of the concrete construction area increases, a large amount of concrete is required, and the number of agitator vehicles 140 required to transport the concrete increases. Furthermore, in order to pour concrete for a large-scale structure, it is necessary to divide the structure into multiple layers depending on the transportable amount of the agitator vehicle 140, etc., and pour concrete in an orderly manner. The number of concrete layers also tends to increase. As a result, there will be many joints, so in order to prevent weak points such as cold joints from occurring, the order of pouring, thickness of pouring layers, etc. should be decided upon, taking into consideration the time required for pouring concrete. I needed to draw up a plan.

The pouring plan is created using, for example, three-dimensional design information including three-dimensional data of a structure designed using three-dimensional CAD (Computer-Aided Design) or the like. The three-dimensional design information also includes information such as the construction area and construction period, for example. The three-dimensional design information is a construction area set according to the amount of concrete that can be placed in a predetermined period, and is divided into a plurality of large blocks. That is, the structure includes a plurality of large blocks. Then, the plurality of large blocks are divided into several small blocks according to the transportable amount of the agitator vehicle 140. In this way, the three-dimensional design information includes division data in which the structure is divided into a plurality of small blocks, and concrete is poured in units of small blocks.

Next, with reference to FIG. 7, an example of the image data table 701 included in the concrete placement management device 600 will be described. The image data table 701 stores an identification number 711 in association with the image data ID 311. The identification number 711 is an identifier for identifying the pump truck 150 to which the fresh concrete transported by the agitator truck 140 is supplied.

The hardware configuration of concrete placement 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 temporary storage work area. The RAM 840 has an area reserved for storing data necessary for realizing this embodiment. Identification number data 841 is data regarding an identifier for identifying pump truck 150.

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

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 truck 150 selected by the worker at the construction site 160. The fourth recording module 852 is a module that records the identification number of the pump truck 150 and the vehicle number of the agitator truck 140 in a linked manner. These modules 851 to 852 are read into the application execution area 446 of the RAM 840 by the CPU 410 and executed. The control program 457 is a program for controlling the entire concrete placement management device 600.

Next, the processing procedure of the concrete placement management device 600 will be explained with reference to the flowchart shown in FIG. This flowchart is executed by the CPU 410 in FIG. 8 using the RAM 840 to realize each functional configuration of the concrete placement management device 600 in FIG. 6.

In step S901, the receiving unit 601 receives an identification number for identifying at least one pump truck 150 placed at the construction site 160. The identification number is a number for identifying the pump truck 150 selected by the worker at the construction site 160. In step S903, the fourth recording unit 602 records the received identification number and the vehicle number of the agitator vehicle 140 in association with each other.

According to this embodiment, since the vehicle number of the agitator vehicle and the identification number of the pump truck are linked and recorded, all information related to concrete can be managed by linking it to small blocks, and the concrete is transported from the manufacturing plant. It is possible to track where fresh concrete has been poured even after pouring is complete.
