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 manages the transportation and placement of concrete by using image data of slips used when transporting and placing ready-mixed concrete and images from cameras installed at the construction site. It is a device for management.

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 information including the shipping time of ready-mixed concrete on the paper slip 120. The worker then hands the slip 120 with the necessary information filled in to the driver of the agitator vehicle 140, which is a transportation vehicle for transporting fresh concrete, and the driver takes the slip 120 and heads toward the construction site 160. and depart.

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 or an employee of the manufacturing plant 130 using a camera 190 installed in a tablet terminal, or by 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.

After reading the written contents, the concrete placement management device 100 records the vehicle number, loading amount, and shipping time read from the slip 120 in association with the number of the license plate 170 of the agitator vehicle 140. 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, unloading of the transported ready-mixed concrete is started. When performing unloading work, the driver of the agitator car 140 moves the agitator car 140 close to the designated pump car 150 according to the guidance of the worker at the construction site 160. Note that in this embodiment, the driver of the agitator vehicle 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 setting the agitator car 140 at a predetermined position relative to the pump car 150, the agitator car 140 is moved backward (backing) to approach the pump car 150. When the agitator car 140 approaches the pump car 150 to a predetermined distance, the fresh concrete storage drum of the agitator car 140 is connected to the pump car 150 through a chute. When the connection between the agitator car 140 and the pump car 150 is completed, fresh concrete is poured from the agitator car 140 to the pump car 150, and when the entire amount of the transported fresh concrete has been poured, the unloading work is completed.

Here, as shown in FIG. 1B, in the present embodiment, the license plate 170 installed on the back of the agitator vehicle 140 approaching the pump vehicle 150 in reverse is, for example, The camera 195 installed on the outrigger 150 captures the image. Then, the concrete placement management device 100 reads the number (vehicle registration number) from the license plate 170 of the agitator vehicle 140 from the image captured by the camera 195. Note that in FIG. 1B, the camera 195 has an angle of view that allows two agitator cars 140 to fit within one frame, but the angle of view of the camera 195 is not limited to this; A camera 195 having an angle of view that accommodates three or more agitator vehicles 140 may be used.

The concrete placement management device 100 then extracts the number of the license plate 170 of the agitator vehicle 140 from the video imaged by the camera 195. The concrete placement management device 100 continues to extract the number of the license plate 170 from the video captured by the camera 195 as long as it can. Then, the concrete placement management device 100 records the time when the number of the license plate 170 is extracted for the first time as the unloading start time, in association with the vehicle number of the agitator vehicle 140 and the number of the license plate 170.

Note that the concrete placement management device 100 determines that the unloading work is continuing while the number of the license plate 170 of the agitator vehicle 140 is extracted from the image captured by the camera 195. In other words, while the number of the agitator car 140 is being extracted, it can be determined that the agitator car 140 is parked near the pump truck 150, so while the number is being extracted, the agitator car 140 is in the process of unloading. It can be determined that

Thereafter, when the unloading work of the agitator car 140 is completed, the chute is removed, and the agitator car 140 leaves the pump car 150, it exits outside the imaging range of the camera 195. In this way, when the agitator car 140 moves out of the imaging range of the camera 195, the number of the agitator car 140 cannot be extracted from the video imaged by the camera 195. Therefore, the concrete placement management device 100 records the time when the number of the agitator vehicle 140 can no longer be extracted as the unloading end time in association with the vehicle number and identification number of the agitator vehicle 140.

As described above, in the concrete placement management device 100, the records from the shipping time at the manufacturing plant 130 to the unloading end time are consistently recorded without the involvement of the driver of the agitator vehicle 140 or the worker at the construction site 160. Concrete placement can be easily and reliably managed.

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 recording section 203, an imaging section 204, an identification number extraction section 205, a start time recording section 206, an end time recording section 207, and a display control section 208.

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. The door number is displayed in a more easily visible position than the vehicle registration number (the number on the license plate 170), so it is easy to monitor using a surveillance camera in the manufacturing factory 130, etc., and 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 recording unit 203 records the read vehicle number, loading amount, shipping time, and identification number of the agitator vehicle 140 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 of the agitator cars 140 to be managed separately. 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 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. 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 can be changed. can be managed. 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 imaging unit 204 images the agitator car 140 after the agitator car 140 arrives at the construction site 160. Here, the camera 195 as the imaging unit 204 is installed, for example, on the outrigger of the pump truck 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 placed within 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 truck 150, the correspondence between the agitator truck 140 and the pump truck 150 to which ready-mixed concrete is supplied becomes clear. Further, the license plate 170 of the agitator vehicle 140 may be imaged by the camera 195 in front.

The identification number extraction unit 205 extracts an identification number for identifying the agitator car 140 from the video imaged by the imaging unit 204 at the timing when the agitator car 140 enters the imaging range of the imaging unit 204. That is, unless the agitator car 140 is included in the frame of the camera 195, the identification number extraction unit 205 cannot extract the identification number because the agitator car 140 is not included in the video 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 (the number of the license plate 170) of the agitator vehicle 140 as the identification number. The identification number extraction unit 205 extracts the vehicle registration number as an identification number because the vehicle number (door number) displayed on the front or side of the agitator vehicle 140 has no fixed display position or font size. This is also because there is a possibility that the numbers will be duplicated. Therefore, the identification number extraction unit 205 extracts the number of the license plate 170, which has a fixed installation position to some extent and has a uniform font size, font, etc., like the license plate 170.

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

That is, when the agitator car 140 approaches the pump truck 150 in reverse and the back of the agitator car 140 fits into the frame of the camera 195, the identification number extraction unit 205 starts to identify the position of the license plate 170. Note that the focal position of the camera 195 is adjusted to the front and rear range including the position where the agitator vehicle 140 is assumed to stop.

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

When the position of the license plate 170 is specified, the identification number extraction unit 205 cuts out, for example, the license plate part of the agitator car 140 from the video imaged by the camera 195, performs character recognition, and extracts the number ( Extract the number).

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 in association with 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 unloading of ready-mixed concrete will begin immediately thereafter. Therefore, the start time recording unit 206 records the time when the number of 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 at which the agitator vehicle 140 exits the imaging range of the imaging unit 204 and is no longer able to extract the identification number from the image captured by the imaging unit 204 as the end of unloading. The time is recorded in association with the vehicle number and identification number. The agitator car 140 immediately leaves the pump car 150 after the unloading work is completed. That is, when the agitator car 140 finishes unloading, it starts moving from the position where the agitator car 140 has been stopped. When the agitator car 140 moves, the agitator car 140 moves out of the frame of the camera 195, so the identification number extraction unit 205 cannot extract the number of the license plate 170 of the agitator car 140. Therefore, the timing at which the identification number extraction unit 205 can no longer 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 for frame-in and frame-out of the agitator vehicle 140 into the frame of the camera 195. Therefore, the concrete placement management device 100 automatically manages the unloading start time and end time based on whether or not the identification number can be extracted. In this way, the concrete placement management device 100 does not require any work by the driver of the agitator vehicle 140 or the workers at the construction site 160, so human errors such as operational errors and input errors can be reduced to the utmost. It is possible.

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 located at the construction site 160. The display control unit 208 displays recorded information on a display of a tablet terminal, smartphone, or the like owned by a worker at the construction site 160, for example. Workers at the construction site 160 manage concrete placement based on the displayed information.

The start time recording unit 206 and the end time recording unit 207 divide the three-dimensional design information of the structure into large blocks of a predetermined size, and record each of the divided large blocks. In the three-dimensional design information having divided data divided into small blocks of a predetermined size, information on the small blocks in which fresh concrete is poured is recorded in association with the vehicle number. 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. 2B. 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.

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, automobile registration number 314, unloading start time 315, and unloading end time 316 in association with image data ID (Identifier) 311.
