Description

The present invention relates to a concrete pouring management device, a concrete pouring management method, and a concrete pouring management program.

In the above technical field, Patent Document 1 discloses that the driver of a ready-mix concrete transport vehicle is required to carry an IC card, and when the driver holds the IC card over a card reader when ready-mix concrete is shipped, when it arrives at the site, and when pouring is completed, the identification information of the transport vehicle, etc. is transmitted to a management server. The management server automatically calculates the shipping time, transportation and waiting time, pouring time, and time until pouring is completed based on the identification information of the transport vehicle and the time it was received, and manages the transport time of ready-mix concrete (paragraph [0041], Figure 2, etc. of the same document).

Below, the embodiments for carrying out the present invention will be described in detail by way of example with reference to the drawings.

[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 and images from a camera installed at the construction site.

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 shipping from the manufacturing plant 130, an employee of the manufacturing plant 130 or the like fills in the necessary information, including the shipping time of the ready-mix concrete, on a paper slip 120. The worker then hands the slip 120 with the necessary information filled in to the driver of the agitator truck 140, which is a transport vehicle for transporting 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 by a camera for reading slips installed at the manufacturing plant 130.

Then, the concrete pouring management device 100 acquires the image data 191 of the voucher 120 that was sent. The concrete pouring management device 100 performs OCR (Optical Character Recognition) processing on the acquired image data 191 of the voucher 120 to read the contents of the voucher 120. The contents read from the voucher 120 are, 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 contents have been read, the concrete pouring management device 100 links the vehicle number, load, and shipping time read from the slip 120 to the number on the license plate 170 of the agitator vehicle 140 and records them. Once these tasks are completed, the driver of the agitator vehicle 140 departs for the construction site 160.

When the agitator truck 140 arrives at the construction site 160, the unloading of the transported ready-mix concrete begins. When unloading, the driver of the agitator truck 140 moves the agitator truck 140 close to the designated pump truck 150, following the guidance of the worker at the construction site 160. Note that in this embodiment, the driver of the agitator truck 140 does not need to wait for the worker at the construction site 160 to fill in the necessary information on the slip 120.

Normally, when the agitator vehicle 140 is set at a predetermined position relative to the pump vehicle 150, the agitator vehicle 140 is driven backwards (backed up) to approach the pump vehicle 150. Then, when the agitator vehicle 140 approaches the pump vehicle 150 to a predetermined distance, the ready-mix concrete storage drum of the agitator vehicle 140 is connected to the pump vehicle 150 by a chute. Once the connection between the agitator vehicle 140 and the pump vehicle 150 is complete, ready-mix concrete is poured from the agitator vehicle 140 into the pump vehicle 150, and when the entire amount of ready-mix concrete that has been transported has been poured, the unloading operation is completed.

As shown in FIG. 1B, in this embodiment, the license plate 170 attached to the back of the agitator vehicle 140 approaching the pump vehicle 150 in reverse (backing) is captured by a camera 195 attached to the outrigger of the pump vehicle 150, for example. The concrete pouring management device 100 then reads the license plate 170 of the agitator vehicle 140 from the image captured by the camera 195, and reads the license plate number (vehicle registration number) from the license plate 170 of the agitator vehicle 140. Note that, in FIG. 1B, a camera 195 with an angle of view that allows two agitator vehicles 140 to fit within one frame is used, but the angle of view of the camera 195 is not limited to this, and a camera 195 with an angle of view that allows one or three or more agitator vehicles 140 to fit within the frame may be used.

Then, the concrete pouring management device 100 extracts the number of the license plate 170 of the agitator vehicle 140 from the image captured by the camera 195. The concrete pouring management device 100 continues to extract the number of the license plate 170 from the image captured by the camera 195 as long as it is possible to extract the number of the license plate 170 from the image captured by the camera 195. The concrete pouring management device 100 then records the time when the number of the license plate 170 is first extracted as the unloading start time, linking it to the vehicle number of the agitator vehicle 140 and the number of the license plate 170.

The concrete pouring management device 100 determines that unloading work is continuing while the number on the license plate 170 of the agitator vehicle 140 is being extracted from the image captured by the camera 195. In other words, while the license plate number of the agitator vehicle 140 can be extracted, it can be determined that the agitator vehicle 140 is parked next to the pump vehicle 150, and therefore it can be determined that unloading work is ongoing while the license plate number is being extracted.

After that, when the unloading of the agitator vehicle 140 is completed, the chute is removed, and the agitator vehicle 140 moves away from the pump vehicle 150, it will exit the imaging range of the camera 195. When the agitator vehicle 140 exits the imaging range of the camera 195 in this way, the license plate number of the agitator vehicle 140 cannot be extracted from the image captured by the camera 195. Therefore, the concrete pouring management device 100 records the time at which it becomes impossible to extract the license plate number of the agitator vehicle 140 as the unloading end time, linking it to the vehicle number and identification number of the agitator vehicle 140.

As described above, the concrete pouring management device 100 automatically records everything from the shipping time from the manufacturing plant 130 to the end of unloading time without the involvement of the driver of the agitator truck 140 or the worker at the construction site 160, making it easy and reliable to manage concrete pouring.

Next, the configuration of the concrete pouring management device 100 will be described with reference to FIG. 2. The concrete pouring management device 100 has an acquisition unit 201, a reading unit 202, a recording unit 203, an imaging unit 204, an identification number extraction unit 205, a start time recording unit 206, an end time recording unit 207, and a display control unit 208.

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 the vehicle registration number (the number on the license plate 170), 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 recording unit 203 records the vehicle number, the load, the shipping time, and the identification number of the agitator vehicle 140 that have been read, in association with each other. Here, any number may be used as the identification number, as long as it is a number that allows each agitator vehicle 140 to be managed separately. 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 recording unit 203 may perform the following process. That is, the 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 (shipping time) of the ready-mixed concrete 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. With the above, a series of processes at the time of shipping ready-mixed concrete is completed, and the transportation management of ready-mixed concrete begins.

After the agitator vehicle 140 arrives at the construction site 160, the imaging unit 204 images the agitator vehicle 140. Here, the camera 195 as the imaging unit 204 is installed, for example, on the outrigger of the pump vehicle 150. However, the installation position of the camera 195 is not limited to this, and may be any position as long as the license plate 170 on the back of the agitator vehicle 140 can be included in the imaging range of the camera 195. For example, the camera 195 may be installed at any position on the construction site 160. Note that if the camera 195 is installed near the pump vehicle 150, the correspondence between the agitator vehicle 140 and the pump vehicle 150 to which the ready-mixed concrete is supplied becomes clear. In addition, the license plate 170 of the agitator vehicle 140 on the front side may be imaged by the camera 195.

The identification number extraction unit 205 extracts an identification number for identifying the agitator vehicle 140 from the image captured by the imaging unit 204 at the timing when the agitator vehicle 140 enters the imaging range of the imaging unit 204. In other words, if the agitator vehicle 140 is not within the frame of the camera 195, the identification number extraction unit 205 cannot extract the identification number because the agitator vehicle 140 is not visible in the image captured by the camera 195. Therefore, the identification number extraction unit 205 starts extracting the identification number at the timing when the agitator vehicle 140 enters the frame of the camera 195.

Here, the identification number extraction unit 205 extracts the vehicle registration number of the agitator vehicle 140 (the number of the license plate 170) as the identification number. The identification number extraction unit 205 extracts the vehicle registration number as the identification number because the vehicle number (door number) displayed on the front and side of the agitator vehicle 140 has no set display position or character size, and there is a possibility of duplicate numbers. For this reason, the identification number extraction unit 205 extracts the number of the license plate 170, which, like the license plate 170, has a set installation position to a certain extent and standardized character size and font.

The identification number is extracted by the identification number extraction unit 205 according to the following procedure. First, the identification number extraction unit 205 identifies the position of the license plate 170 in the image captured by the camera 195. The position of the license plate 170 is identified, for example, using image recognition by artificial intelligence (AI), but is not limited to this. For example, a technology such as character recognition by OCR processing may be used.

That is, when the agitator vehicle 140 approaches the pump vehicle 150 in reverse and the back of the agitator vehicle 140 fits into the frame of the camera 195, the identification number extraction unit 205 begins to identify the position of the license plate 170. Note that the focal position of the camera 195 is set to a range in front of and behind the position where the agitator vehicle 140 is expected to stop.

In addition, in the case of an agitator vehicle 140, the position where the license plate 170 is displayed is almost fixed for each vehicle body, so the position of the license plate 170 is relatively easy to identify in the image captured by the camera 195. Note that the license plate 170 of the agitator vehicle 140 is almost always installed next to the hopper of the agitator vehicle 140, but it may be installed in another location. Therefore, the identification number extraction unit 205 first identifies the position of the license plate 170.

Once the position of the license plate 170 has been identified, the identification number extraction unit 205 cuts out, for example, the license plate portion of the agitator vehicle 140 from the image captured by the camera 195, performs character recognition, and extracts the numbers (numbers) on the license plate 170.

The start time recording unit 206 records the time when the identification number is first extracted by the identification number extraction unit 205 as the unloading start time, linking it to the vehicle number and the identification number. In other words, when the agitator vehicle 140 approaches the pump vehicle 150 to a position where the number on the license plate 170 can be read, it can be expected that the unloading of ready-mix concrete will start immediately after that. Therefore, the start time recording unit 206 records the time when the number on the license plate 170 is first extracted by the identification number extraction unit 205 as the unloading start time.

The end time recording unit 207 records the time when the agitator vehicle 140 leaves the imaging range of the imaging unit 204 and the identification number can no longer be extracted from the image captured by the imaging unit 204 as the unloading end time, linking it to the vehicle number and the identification number. When the unloading operation is completed, the agitator vehicle 140 promptly leaves the side of the pump vehicle 150. In other words, when unloading is completed, the agitator vehicle 140 starts moving from the position where the agitator vehicle 140 was stopped. When the agitator vehicle 140 moves, the agitator vehicle 140 goes out of the frame of the camera 195, and the identification number extraction unit 205 is no longer able to extract the number of the license plate 170 of the agitator vehicle 140. Therefore, the time when the identification number extraction unit 205 is no longer able to extract the license plate number of the agitator vehicle 140 is set as the end time of unloading of the agitator vehicle 140.

As described above, in this embodiment, the timing for determining the start and end of unloading is the timing when the agitator truck 140 enters and leaves the frame of the camera 195. Therefore, the concrete pouring management device 100 automatically manages the start and end times of unloading based on whether or not the identification number can be extracted. In this way, the concrete pouring management device 100 does not require any work by the driver of the agitator truck 140 or the worker at the construction site 160, making it possible to minimize human errors such as operating errors and input errors.

The display control unit 208 displays at least one of the recorded vehicle number, loading amount, shipping time, unloading start time, and unloading end time on the display of a mobile terminal placed at the construction site 160. The display control unit 208 displays the recorded information on the display of, for example, a tablet terminal or smartphone carried by a worker at the construction site 160. The worker at the construction site 160 manages the pouring of concrete based on the displayed information.

The start time recording unit 206 and end time recording unit 207 record information on small blocks into which ready-mix concrete has been poured, in three-dimensional design information of a structure, in which the three-dimensional design information is divided into large blocks of a predetermined size, and each of the divided large blocks has division data divided into small blocks of a predetermined size, in association with the vehicle number. Information on which agitator vehicle 140 with which vehicle number unloaded concrete onto which pump vehicle 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, for example, in the form of a document as shown in FIG. 2B. In addition to the vehicle number of the agitator vehicle 140, identification numbers such as license plate numbers may also be recorded in the document.

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.

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 an 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, vehicle registration number 314, unloading start time 315, and unloading end time 316 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 content read by OCR processing from the image data 191 of the slip 120, and includes the vehicle number, shipping time, load amount, etc. The vehicle registration number 314 is the number of the license plate 170 of the agitator vehicle 140 extracted by the identification number extraction unit 205. The unloading start time 315 is the time when the number of the license plate 170 of the agitator vehicle 140 is extracted for the first time, which is set as the start time of unloading. The unloading end time 316 is the time when the number of the license plate 170 of the agitator vehicle 140 can no longer be extracted, which is set as the end time of unloading.

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.

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, the shipping time of the ready-mixed concrete, and the like, which are written on the slip 120.

In step S505, the 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 recording unit 203 proceeds to step S507. In step S507, the 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 recording unit 203 proceeds to step S509. In step S509, the 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 imaging unit 204 images the agitator vehicle 140 that has arrived at the construction site 160. In step S513, the concrete pouring management device 100 determines whether or not the number on the license plate 170 of the agitator vehicle 140 can be extracted from the image captured by the imaging unit 204. If it is determined that the number cannot be extracted (NO in step S513), the concrete pouring management device 100 continues imaging and extraction. If it is determined that the number can be extracted, the concrete pouring management device 100 proceeds to step S515.

In step S517, the concrete pouring management device 100 determines whether the number on the license plate 170 of the agitator vehicle 140 can no longer be extracted from the video captured by the imaging unit 204. If it is determined that the number can be extracted (NO in step S517), the concrete pouring management device 100 continues processing. If it is determined that the number can no longer be extracted (YES in step S517), the concrete pouring management device 100 proceeds to step S519.

In step S519, the end time recording unit 207 records the time when it becomes impossible to extract the number from the license plate 170 of the agitator vehicle 140 as the unloading end time, linking it to the vehicle number and number of the agitator vehicle 140. In step S521, the display control unit 208 displays at least one of the recorded vehicle number, load, shipping time, unloading start time, and unloading end time on the display of a mobile terminal placed at the construction site 160.

According to this embodiment, the details written on the shipping slip when the concrete is shipped are used as is, and after the agitator truck arrives at the construction site, the start and end of unloading is managed using camera footage, so there is no room for human error. In addition, since image data from the shipping slip and footage captured by the camera are used, concrete pouring can be managed quickly and reliably, despite the simple method.
