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. First, as shown in FIG. 1A, a case will be considered in which ready-mixed concrete manufactured at a manufacturing factory 130 is shipped from the manufacturing factory 130 and transported to a 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.

When the agitator vehicle 140 arrives at the construction site 160, the driver hands the slip 120 to a worker at the construction site 160, and the worker writes the arrival time of the agitator vehicle 140 on the slip 120. As described above, in concrete transportation and pouring operations, various types of management such as transportation management and quality certification of ready-mixed concrete have been performed by passing paper slips 120.

Therefore, in the concrete placement management device 100, we focused on the paper slip 120 that has been widely used in the past, and performed predetermined processing on the paper slip 120 (analog data) to digitize the written contents of the slip 120. By recording and using it as data, it is possible to manage not only the transport of concrete but also the placement of concrete.

First, when the agitator car 140 departs from the manufacturing factory 130, the driver of the agitator car 140, the employee of the manufacturing factory 130, etc. captures an image of the slip 120 with a camera 190 installed in a mobile terminal such as a tablet terminal. 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 captured using a camera 190 installed in a mobile terminal owned by the driver of the agitator vehicle 140 or an employee of the manufacturing plant 130, or by using a slip reader installed in the manufacturing plant 130. A standard camera may also 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. When the reading of the written contents is completed, the concrete placement management device 100 records the vehicle number, loading amount, shipping time, etc. read from the slip 120 in association with each other.

Thereafter, the agitator vehicle 140 transports the loaded ready-mixed concrete to the construction site 160. When the agitator vehicle 140 arrives at the construction site 160, the driver of the agitator vehicle 140 or the worker at the construction site 160 images the slip 120 with a camera 195 installed in a portable terminal such as a tablet terminal. When the image capturing of the slip 120 is completed, the driver or the like transmits the image data 196 of the imaged slip 120 to the concrete placement management device 100 via wireless communication or wired communication.

Note that the image of the slip 120 at the construction site 160 is taken using a camera 195 installed in a mobile terminal owned by the driver of the agitator vehicle 140 or the worker at the construction site 160; A camera for reading slips 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 196 of the sent slip 120. The concrete placement management device 100 performs OCR processing on the image data 196 of the acquired slip 120 and reads the written contents of the slip 120. The concrete placement management device 100 reads the vehicle number of the agitator vehicle 140 from the image data 196 of the slip 120. The concrete placement management device 100 records the time when the slip 120 is read by the camera 195 as the arrival time of the agitator vehicle 140 at the construction site 160 in association with the read vehicle number. The concrete placement management device 100 displays at least one of the recorded vehicle number, loading amount, shipping time, and arrival time on the display of the mobile terminal.

Here, reading the written contents of the slip 120 will be explained with reference to FIG. 1B. In FIG. 1B, a slip image 171, which is image data 191 (or image data 196) of the captured slip 120, is displayed on the left side of the screen 170, and a read image 181, which is the read content, is displayed on the right side of the screen 170. Displayed.

The written contents of the slip 120 are displayed in the slip image 171. The contents of the slip image 171 include a slip title 172, date 173, destination 174, manufacturing factory name 175, delivery location 176, transport vehicle number 177, delivery time 178, delivery volume 179, type 180, and the like. Note that the transport vehicle number 177 corresponds to the vehicle number described above.

Then, the concrete placement management device 100 reads the written contents listed here. The written contents that the concrete placement management device 100 mainly reads include the vehicle number of the agitator vehicle 140 (transport vehicle number 177), the load capacity of ready-mixed concrete (delivery volume 179), and the shipping time of ready-mixed concrete (delivery time 178). However, it is not limited to these.

Next, the configuration of the concrete placement management device 100 will be described with reference to FIG. 2A. The concrete placement management device 100 includes a first acquisition section 201, a first reading section 202, a first recording section 203, a second acquisition section 204, a second reading section 205, a second recording section 206, and a display control section 207. .

The first acquisition unit 201 reads and generates a slip, which is used when transporting ready-mixed concrete manufactured at a ready-mixed concrete manufacturing factory to a concrete placement site, using a first imaging device at the time of shipping the ready-mixed concrete. The first image data of the issued slip 120 is obtained. 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 the concrete placement management device 100, in order to be able to use the paper slip 120, a camera 190 (first imaging device) of a mobile terminal owned by the driver of the agitator vehicle 140, etc. is used to The document 120 is read (imaged) and image data 191 is generated.

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 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 first acquisition unit 201 then acquires image data 191 (first image data) 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 first reading unit 202 reads the vehicle number of the transport vehicle (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 first image data (image data 191). The first 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 first 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 is something. 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 first reading unit 202 because the written contents of the slip 120 are unclear or the written position is blurred, the first recording unit 203 performs the following processing. . 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 writing position, the transportation time (shipment time) of the ready-mixed concrete You can manage your typing time. As described above, a series of processing at the time of shipment of ready-mixed concrete is completed, and transportation management of ready-mixed concrete is started.

The second acquisition unit 204 reads and generates the slip 120 using a second imaging device included in a mobile terminal owned by a worker at the construction site 160 when the transport vehicle arrives at the construction site 160. image data 196 is acquired. That is, when the fresh concrete transported by the agitator vehicle 140 arrives at the construction site 160, the driver of the agitator vehicle 140 hands over the slip 120 to the worker at the construction site 160. The worker at the construction site 160 who received the slip enters the arrival time of the agitator vehicle 140 and other necessary information on the received slip 120.

Then, the worker at the construction site 160 reads the slip 120 in which the arrival time and other information is written, using a camera 195 (second imaging device) installed on a mobile terminal such as a tablet terminal that he/she owns, and reads the slip 120. Image data 196 is generated. The generated image data 196 is transmitted from the worker's mobile terminal to the concrete placement management device 100 via wireless communication or wired communication.

The second acquisition unit 204 then receives and acquires the image data 196 transmitted from the worker's mobile terminal. In addition, here, an example has been described in which the image data 196 of the slip 120 is generated using the camera 195 of a mobile terminal owned by a worker at the construction site 160. Image data 196 may also be generated. Further, instead of using a mobile terminal carried by a worker or a driver, for example, a camera installed at the construction site 160 may be used to read the slip 120 and generate the image data 196.

The second reading unit 205 reads the vehicle number written on the slip 120 from the image data 196. The second reading unit 205 reads the vehicle number of the agitator vehicle 140 by performing OCR processing on the acquired image data 196. In other words, the loading amount and the like read by the first reading unit 202 do not change between the time of departure from the manufacturing factory 130 and the time of arrival at the construction site 160, so there is no need to read the contents of such a slip 120.

That is, when the agitator vehicle 140 arrives at the construction site 160, if the vehicle number written on the slip 120 can be determined, the shipping time and loading amount of ready-mixed concrete can be easily extracted. In other words, information such as shipping time and loading amount of ready-mixed concrete has already been linked and recorded in the first recording unit 203, and this information does not change while concrete is being poured. It is from. Therefore, the second reading unit 205 reads the vehicle number of the agitator vehicle 140. Note that the second reading unit 205 can also read the contents written on the slip 120 other than the vehicle number (such as arrival time), but by limiting the read contents, the processing time in the second reading unit 205 can be shortened. I can do it.

Next, the second recording unit 206 records the time when the slip 120 was read by the second imaging device as the arrival time of the transport vehicle at the construction site 160, linking it to the vehicle number read by the second reading unit 205. do. For example, when the driver of the agitator vehicle 140 (transport vehicle) arrives at the construction site 160, he hands the slip 120 to a worker at the construction site 160 and asks him to fill in the arrival time. Therefore, the second recording unit 206 may read the arrival time written on the slip 120 by performing OCR processing on the slip 120 on which the arrival time is written.

However, since ready-mixed concrete has a limited time from manufacture to completion of pouring, the agitator vehicle 140 arrives at the construction site 160 and immediately starts unloading to complete concrete pouring. This is desirable. Furthermore, for example, if the arrival time is not entered in the correct position on the slip 120, OCR processing may not be possible or processing will take time, and unloading operations may be delayed until OCR processing is completed. You will not be able to start the process, and you will lose a lot of time.

Therefore, the second recording unit 206 does not record the arrival time read from the slip 120, but records the time when the slip 120 is read by the camera 195 (second imaging device) as the arrival time of the agitator vehicle 140. ing. Note that reading of the slip 120 by the camera 195 is performed in a relatively short period of time after the agitator vehicle 140 arrives at the construction site 160, so that processing can be performed in this manner. This reduces the time lost when arriving at the pouring site due to reading the contents of the slip 120, and allows the driver of the agitator vehicle 140 and the workers at the construction site 160 to smoothly move on to the next task. Become.

Further, the second recording unit 206 may record the recorded arrival time as the unloading start time of the ready-mixed concrete. That is, when the agitator vehicle 140 arrives at the construction site 160, the driver of the agitator vehicle 140 and the worker at the construction site 160 begin unloading the fresh concrete that has been transported. For example, 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. As the start time for transferring the fresh concrete, the time when the agitator vehicle 140 arrives at the construction site 160 may be recorded as the time to start unloading the fresh concrete.

Note that the concrete unloading start time may be recorded together with an identification number for identifying the pump truck 150. For example, if one second reading unit 205 is installed at the entrance/exit of the construction site 160 and one pump truck 150 is installed at the construction site 160, the agitator truck 140 and unloading Since there is a one-to-one correspondence with the pump truck 150, the correspondence is clear.

However, when a plurality of pump trucks 150 are arranged at the construction site 160, the pump trucks 150 are recorded using a mobile terminal such as a tablet terminal at the place where the pump trucks 150 unload concrete. . This makes it possible to link and record the agitator car 140 that has transported fresh concrete and the pump car 150 that has unloaded the transported fresh concrete, and to record the agitator car 140 and pump car 150. A one-to-one correspondence is possible.

Therefore, it is possible to confirm which agitator car 140 has unloaded concrete to which pump car 150. Further, the unloading end time may also be recorded. The unloading end time may be recorded based on the time when a worker near the pouring site in the construction site 160 operates a mobile terminal such as a tablet terminal.

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 transportation 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.

The display control unit 207 displays at least one of the recorded vehicle number, loading amount, shipping time, and arrival time on the display of the mobile terminal. The display control unit 207 displays the recorded data on the display of a mobile terminal such as a tablet terminal owned by a worker at the construction site 160, for example. This allows workers at the construction site 160 to compare the pouring work at the construction site 160 with the recorded transportation and pouring data and check the progress of the work and the degree to which the plan has been achieved. can.

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, reading content data 313, and reading time 314 in association with an image data ID (Identifier) 311. The image data ID 311 is an identifier for identifying the image data of the slip 120 captured by the cameras 190 and 195. The image data information 312 is, for example, information regarding the imaging conditions and imaging time of the slip 120. The read content data 313 is data about the content read from the image data 191 and the image data 196 of the slip 120 by OCR processing, and includes the vehicle number, shipping time, loading amount, and the like. The reading time 314 is the time when the image data 196 was read by the camera 195.

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 when shipped from the manufacturing factory 130 and when arrived at the construction site 160. 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 linking data 444 is data such as the vehicle number of the agitator vehicle 140 and the shipping time linked to the vehicle number.

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 a first acquisition module 451, a first reading module 452, a first recording module 453, a second acquisition module 454, a second reading module 455, a second recording module 456, and a display control module 457. The first acquisition module 451 is a module that acquires the image data 191 of the slip 120. The first 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.

[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 third recording section 601. 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 third recording unit 601 sets the time when the worker at the construction site 160 presses the button displayed on the display of the mobile terminal for recording the unloading end time of the ready-mixed concrete as the end time for unloading the ready-mixed concrete. , and record it by linking it to the vehicle number. In the concrete placement management device 100 according to the first embodiment, fresh concrete is transported to the construction site 160 and managed until the timing of starting unloading. By also managing the timing of the end of unloading, it becomes possible to manage a series of operations from the start of transporting ready-mixed concrete to the end of unloading.

Therefore, when a worker at the construction site 160 presses a button for recording the unloading end time displayed on the display of a mobile terminal owned by the worker, the third recording unit 601 outputs a signal indicating that the button has been pressed. Receive. Then, the third recording unit 601 records the button press time included in the signal in association with the vehicle number of the agitator vehicle 140 as the unloading end time of the ready-mixed concrete. This makes it possible to manage a series of operations until the unloading of concrete is completed.

Further, the third recording unit 601 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 a small block of a predetermined size. In the three-dimensional design information having divided data, information on small blocks on which concrete has been placed is recorded in association with the vehicle number. By recording information on small blocks where concrete has been placed in association with the vehicle number of the agitator vehicle 140, it becomes possible to manage the location where concrete has been placed based on the vehicle number. In addition, on the contrary, it is possible to trace back from the information on the small block to see in which manufacturing factory the concrete poured into the small block was manufactured and how it was transported. 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 a press time 711 and a placement location 712 in association with the image data ID 311. The press time 711 is the time when the worker at the construction site 160 presses the button for recording the concrete unloading end time displayed on the display of the mobile terminal, and is recorded together with the vehicle number of the agitator vehicle 140. . The pouring site 712 is a place where fresh concrete transported by the agitator vehicle 140 is poured.

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. A storage area is secured in the RAM 840 to store data necessary for realizing this embodiment. The press time data 841 is the time when the worker at the construction site 160 presses the button for recording the unloading end time displayed on the display of the mobile terminal. The placement location data 842 is data about the location where concrete transported by the agitator vehicle 140 from the manufacturing factory 130 is to be poured.

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 press time 711, and the placement location 712.

The storage 850 further stores a third recording module 851. The third recording module 851 links the time when the worker at the construction site 160 presses the button for recording the unloading end time displayed on the display of the mobile terminal to the vehicle number as the unloading end time. This is a recording module. This module 851 is read into the application execution area 446 of the RAM 840 by the CPU 410 and executed.

Next, the processing procedure of the concrete placement management device 600 will be explained with reference to the flowchart of 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 third recording unit 601 sets the vehicle number as the unloading end time by the time when the worker at the construction site 160 presses the button for recording the unloading end time displayed on the display of the mobile terminal. Record it by linking it to. In step S903, the third recording unit 601 records information on the small block into which concrete has been poured, in association with the vehicle number of the agitator vehicle 140.

According to this embodiment, since the unloading end time is recorded in association with the vehicle number, all information related to concrete can be managed in association with small blocks, starting from the shipment of ready-mixed concrete from the manufacturing factory. It is possible to reliably manage a series of operations for pouring concrete, up to the end of unloading fresh concrete at the construction site 160, and subsequently.
