Description

[Technical Field]

[0001] The present invention relates to technology related to the pouring of fresh concrete, and more specifically to a pouring information management system that can manage concrete pouring information based on various information obtained at the pouring site, such as various information obtained by image recognition of delivery notes (invoices) related to agitator trucks and images obtained by photographing agitator trucks. [Background technology]

[0002] Along with steel, concrete is one of the most important construction materials, and is used in a variety of structures, including civil engineering structures such as dams, tunnels, and bridges, as well as architectural structures such as apartment buildings and office buildings. While these concrete structures are sometimes prefabricated in factories and transported to their designated locations, civil engineering and architectural structures are often constructed directly at the designated location (site). In either case, concrete structures are constructed by pouring fresh concrete, a mixture of cement, water, aggregate, admixtures, etc., into formwork, waiting for the concrete to harden, and then removing the formwork.

[0003] Fresh concrete is poured into the formwork by being poured through a chute from an agitator truck, dropped from a hose by a concrete pump truck, poured into the designated location through pre-installed pipes, or in some cases by workers splashing it with a shovel. The fresh concrete poured into the formwork is then compacted using a vibrator (vibrating vibrator). When the vibrating vibrator vibrates the concrete, it liquefies, and as it liquefies further, the air bubbles within the concrete rise and escape, and the aggregate and mortar within the concrete are rearranged, resulting in the concrete being compacted.

[0004] When pouring concrete, work plans are drawn up in advance, such as creating a construction plan, and then construction management is carried out to ensure that the actual pouring is carried out according to the plan. Construction management also requires the timely acquisition of various information, and particularly at large-scale concrete pouring sites, it is common to manage information such as concrete pouring time and concrete pour volume in real time.

[0005] Here, concrete pouring time refers to the time from the start of mixing the concrete to the end of pouring. In order to ensure the quality of concrete, the "Concrete Standard Specifications - Construction Edition - (hereinafter simply referred to as the "Standard Specifications") stipulates that the standard concrete pouring time should be within 2 hours when the outside temperature is 25°C or below, and within 1.5 hours when the outside temperature is above 25°C. Therefore, managing the concrete pouring time in real time during concrete pouring work is extremely important in ensuring the quality of concrete.

[0006] The amount of concrete poured is the actual amount of concrete poured. Naturally, the planned amount of concrete to be poured is set, and as this planned amount approaches, a decision must be made as to how many remaining agitator trucks to request. At this time, the amount of concrete poured up to that point is the deciding factor in determining the number of trucks to request.

[0007] In the past, the construction manager stationed at the concrete pouring site visually checked the concrete pouring time and amount. Specifically, after receiving a delivery slip from the agitator truck driver, the manager would check the concrete pouring time by comparing the delivery time (which can be considered the mixing start time) listed on the delivery slip with the current time, or the amount of concrete poured based on the amount of concrete listed on the delivery slip.

[0008] However, when multiple concrete pump trucks are deployed, it is not so easy to grasp the amount of concrete poured in real time. Construction managers are only able to grasp the actual amount of concrete pump trucks they are responsible for, and in order to grasp the overall amount, an information aggregator must collect and consolidate information successively from each construction manager. Although the delivery slip for the agitator truck shows the cumulative amount of concrete that has been transported up to that point, this cumulative amount is a value for each concrete shipping plant, and is not very useful in cases where concrete is transported from multiple concrete shipping plants.

[0009] As described above, in the past, construction managers were assigned to each concrete pouring location, and large-scale construction sites where concrete was poured using multiple concrete pump trucks required the hiring of numerous construction managers. Furthermore, when multiple concrete pump trucks were deployed and concrete was transported from multiple concrete shipping plants, it was difficult to grasp the amount of concrete being poured in real time. To address this issue, various technologies have been proposed to easily manage concrete pouring time and amount in real time. For example, Patent Document 1 proposes a technology that displays information about the manufacturing plant (concrete shipping plant) based on various information related to the ready-mix concrete transport vehicle (agitator truck), and also displays the location of the agitator truck. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-27152 Summary of the Invention [Problem to be solved by the invention]

[0011] The technology disclosed in Patent Document 1 requires that a positioning device (for example, a satellite radio wave receiver) be installed on the agitator vehicle to display its location, which means that cooperation must be sought from the concrete shipping plant. Also, in order to display the location of an agitator vehicle along with information about the concrete shipping plant, it is necessary to associate and store in advance information for identifying each agitator vehicle, information about the concrete shipping plant associated with the agitator vehicle, information about the positioning device installed on the agitator vehicle, etc., but researching and inputting this information requires considerable effort and cost.

[0012] The object of the present invention is to solve the problems associated with conventional technology, namely, to provide technology that can manage concrete pouring information without having to assign a construction manager to the pouring site and without having to request cooperation from the concrete shipping factory. [Means for solving the problem]

[0013] The present invention was made with a focus on identifying an agitator vehicle using the vehicle registration number plate (so-called license plate) in the image, and obtaining concrete specification information by image recognition of the delivery note related to the agitator vehicle, and is an invention based on an unprecedented idea.

[0014] The pouring information management system of the present invention manages pouring information related to concrete pouring based on images of a vehicle transporting fresh concrete. It includes a pouring site photographing means, a site vehicle information reading means, a specification information reading means, and a sequential pouring information generating means. The pouring site photographing means is a means for capturing video (or continuous still images) of a vehicle deployed at a concrete pouring site to acquire a "pouring site image." The site vehicle information reading means is a means for reading "vehicle number information" included in the "vehicle registration plate" of a vehicle captured in the pouring site image by image recognition of the pouring site image. The specification information reading means is a means for reading a delivery slip containing "concrete specification information" related to the fresh concrete loaded on the vehicle and generating "specification text data" by converting the information included in the concrete specification information into text data. The sequential pouring information generating means is a means for generating a set of "sequential pouring information" from the "vehicle number information" and the "specification text data." The specification text data includes the time when mixing of fresh concrete started, the amount of fresh concrete loaded on the transport vehicle, and "transport vehicle identification information" that identifies the transport vehicle. The sequential pouring information generating means generates sequential pouring information for each transport by the transport vehicle, and generates sequential pouring information using the on-site photographing time and specification text data related to the same transport vehicle based on the "transport vehicle correspondence table" in which vehicle number information and transport vehicle identification information are associated.

[0015] The concrete pouring information management system of the present invention can further include a gate entry photographing means and a gate vehicle information reading means. The gate entry photographing means is a means for capturing video (or continuous still images) of a transport vehicle entering the entrance of a construction yard including a concrete pouring site to obtain a gate entry image, and the gate vehicle information reading means is a means for reading vehicle number information related to the transport vehicle contained in the gate entry image by image recognition of the gate entry image. In this case, the sequential pouring information generating means includes the "gate photographing time" at which the gate entry image was obtained in the sequential pouring information related to the same transport vehicle.

[0016] The concrete pouring information management system of the present invention may further include a vehicle status determination means. This vehicle status determination means, when a concrete pouring site image is acquired, determines whether the vehicle is in a "vehicle deployed state (a state in which the vehicle is deployed to the concrete pouring site)" or a "vehicle exited state (a state in which the vehicle has exited the concrete pouring site)" based on the vehicle number information associated with the concrete pouring site image. In this case, the vehicle status determination means determines the vehicle as in a "vehicle deployed state" when the number of consecutive reads of the same vehicle number information exceeds a predetermined consecutive deployment threshold, or when the number of times the same vehicle number information is read out of a predetermined number of determinations exceeds a predetermined deployment percentage threshold. The vehicle status determination means also determines the vehicle as exited when the number of consecutive reads of the same vehicle number information falls below a predetermined consecutive exit threshold, or when the number of times the same vehicle number information is read out of a predetermined number of determinations falls below a predetermined exit percentage threshold.

[0017] The input information management system of the present invention may further include input time determination means. This input time determination means determines a "start time of input" for a transport vehicle based on the determined time of the transport vehicle's vehicle location status, and determines a "end time of input" for the transport vehicle based on the determined time of the transport vehicle's vehicle exit status. In this case, the sequential input information generation means includes the start time of input and the end time of input in the sequential input information for the same transport vehicle.

[0018] The drive-in information management system of the present invention can also determine the drive-in start time and drive-in end time based on a predetermined judgment period. In this case, the drive-in time determination means determines the judgment time as the drive-in start time when no other judgment has been made within a period going back by the judgment period from the judgment time of the transport vehicle deployment state, and determines the judgment time as the drive-in end time when no other judgment has been made even after the judgment period has passed since the judgment time of the transport vehicle exit state.

[0019] The pouring information management system of the present invention may further include a guide display means. This guide display means is installed at the entrance of a construction yard including a concrete pouring site and displays the concrete pump truck that should be headed for a transport vehicle entering the entrance. In this case, two or more concrete pump trucks are arranged in the construction yard, and two or more pouring site photography means are arranged corresponding to each concrete pump truck. The pouring time determination means determines the pouring start time and pouring end time for each pouring site photography means. After the pouring end time has been determined, the guide display means displays the concrete pump trucks corresponding to the pouring site photography means for which the pouring start time has not yet been determined.

[0020] The pouring information management system of the present invention may further include an overflow warning information output means. This overflow warning information output means outputs "overflow warning information" indicating that a predetermined time has elapsed since the start of fresh concrete. In this case, when the interval between the mixing start time and the on-site photographing start time (the start time of acquiring pouring site images) for the same transport vehicle exceeds a predetermined concrete elapsed time threshold, the overflow warning information output means outputs the overflow warning information.

[0021] The input information management system of the present invention may further include a warning information output means for outputting "read warning information" indicating that the delivery note has not been image-recognized. In this case, if the specification information reading means has not generated specification text data even after a predetermined reading time threshold has elapsed since the start of on-site photography, the warning information output means outputs the reading warning information.

[0022] The driving-in information management system of the present invention may also be equipped with a driving-in site photographing means that allows the angle of view to be adjusted by remote control by an operator. [Effects of the Invention]

[0023] The driving information management system of the present invention has the following effects. (1) There is no need to assign a construction manager to each installation location, which means that the number of construction managers that need to be secured can be reduced, thereby reducing labor costs. (2) There is no need to rely on others, such as concrete shipping factories, and the contractor can carry out the work at their own discretion. (3) Even when multiple concrete pump trucks are deployed, concrete pouring information can be easily managed in real time. (4) The on-site vehicle information reading means and the gate vehicle information reading means transmit text data after image recognition processing, rather than image data, so that the amount of communication can be reduced, and as a result, communication speed is improved. (5) By using a means of photographing the driving site, which allows the operator to adjust the angle of view by remote control, the situation at the site can be checked from a remote location such as the management building or supervisor's station.

[0025] An embodiment of the drive-in information management system of the present invention will be described with reference to the drawings.

[0026] 1.Definition Before describing an embodiment of the drive-in information management system of the present invention, definitions of terms used herein will be provided.

[0027] (Pouring information and concrete specifications) One of the technical features of the present invention is the management of information related to concrete pouring in real time while it is being poured. For convenience, information related to concrete pouring will be referred to simply as "concrete pouring information." This pouring information includes information (hereinafter referred to as "vehicle number information") that identifies a mobile vehicle capable of transporting fresh concrete, such as an agitator vehicle (hereinafter referred to as "transport vehicle"), and "concrete specification information."

[0028] Here, concrete specification information refers to information about fresh concrete loaded onto a transport vehicle at a concrete shipping factory (concrete manufacturing plant), and is information written on the "delivery note (invoice)" handed over to the recipient of the fresh concrete. It includes the time when mixing of the fresh concrete began, the amount of fresh concrete loaded (amount per transport), and identification information that identifies the transport vehicle (hereinafter referred to as "transport vehicle identification information"), and can also include the type and mix of concrete, the cumulative amount of fresh concrete shipped from the concrete shipping factory, etc.

[0029] While the present invention can be applied to various types of concrete, it is particularly suited to ready-mixed concrete as defined by the Japanese Industrial Standards (JIS). For ready-mixed concrete conforming to the JIS standard, the delivery slip contains concrete specifications such as the name of the manufacturing plant, delivery time (departure), delivery volume, and delivery truck number, ensuring reliable implementation of the present invention. Furthermore, even when using ready-mixed concrete that does not conform to the JIS standard, or when the delivery slip format differs between regional associations, the delivery slip generally conforms to the JIS standard, making it possible to fine-tune the specifications for JIS ready-mixed concrete. For ready-mixed concrete conforming to the JIS standard, the delivery slip contains the "delivery time (departure)," which can be considered the "mixing start time." Therefore, for convenience, the "delivery time (departure)" will also be referred to as the "mixing start time."

[0030] The "vehicle number information" of the transport vehicle included in the pouring information is all or part (for example, the last four digits) of the "automobile registration number plate (the symbol or number printed on the license plate)" attached to the transport vehicle. On the other hand, the "transport vehicle identification information" included in the concrete specification information is identification information that can be used to distinguish the transport vehicle from other transport vehicles (i.e., it is unique), but it is set using the "agitator vehicle number" attached by the concrete shipping plant, etc., and is not information related to the automobile registration number plate. In other words, the vehicle number information and the transport vehicle identification information are different pieces of information.

[0031] While the present invention has been described as managing pouring information in real time, it goes without saying that concrete specification information differs for each vehicle, and therefore for each transport, and therefore for each pouring information. Therefore, in the present invention, pouring information is generated each time a vehicle transports fresh concrete, in other words, for each transport and for each vehicle. For convenience, the pouring information for each transport by a vehicle is referred to as "sequential pouring information." In other words, multiple pieces of sequential pouring information are generated as the concrete is poured, and the collection of these multiple pieces of sequential pouring information constitutes the "pouring information."

[0032] (Construction yard and concrete pouring site) Figure 1 is a plan view that shows a schematic diagram of concrete being poured using the pouring information management system of the present invention. In this figure, concrete is being poured to build a circular structure in plan view, and three concrete pump trucks are deployed, each with two transport vehicles AG. Of course, the pouring information management system of the present invention can be implemented in cases where only one concrete pump truck is deployed, or in cases where two or more concrete pump trucks are deployed, as shown in Figure 1.

[0033] In Figure 1, three concrete pump trucks are deployed, allowing fresh concrete to be poured from three locations. For convenience, the area surrounding the location where the fresh concrete is actually poured (in other words, the pouring point), such as the nozzle of the concrete pump truck, will be referred to as the "concrete pouring site." For example, in Figure 1, the first concrete pump truck PCa and two transport vehicles AG form the "first concrete pouring site a," while the second concrete pump truck PCb and two transport vehicles AG form the "second concrete pouring site b," and the third concrete pump truck PCc and two transport vehicles AG form the "third concrete pouring site c."

[0034] Generally, a temporary fence is set up around the site where concrete is poured to prevent third parties from easily entering, forming an area that includes the concrete pouring site. For convenience, we will refer to this area that includes the concrete pouring site as the "construction yard YD." As shown in Figure 1, the construction yard YD is equipped with a gate (hereinafter referred to as the "entrance gate GT") for transport vehicles AG and the like to enter.

[0035] (Images of the driving site and gate entrance) At each concrete pouring site, equipment for photographing the transport vehicle AG (hereinafter referred to as "pouring site photographing means 101") is installed, and near the entrance GT, equipment for photographing the transport vehicle AG entering through the entrance GT (hereinafter referred to as "gate entrance photographing means 105") is installed. For example, in Figure 1, a first pouring site photographing means 101a is installed at the first concrete pouring site a, and similarly, a second pouring site photographing means 101b is installed at the second concrete pouring site b, and a third pouring site photographing means 101c is installed at the third concrete pouring site c, and gate entrance photographing means 105 is installed near the entrance GT.

[0036] The driving site photographing means 101 and the gate entrance photographing means 105 photograph the transport vehicle AG as video or continuous still images. Devices capable of transmitting captured images in real time, such as network cameras, smartphones, and tablet PCs, can be used. Both video and continuous still images are composed of images (frames) captured at extremely short intervals. While video generally refers to images captured at 24 to 60 frames per second (i.e., 24 to 60 fps), continuous still images are defined as images captured at less than 24 fps or more than 60 fps. For convenience, the images (frames) captured by the driving site photographing means 101 will be referred to as "driving site images," and the images captured by the gate entrance photographing means 105 will be referred to as "gate entrance images." Furthermore, the time at which the driving site photographing means 101 captures the driving site image will be referred to as the "site photographing time," and the time at which the gate entrance photographing means 105 captures the gate entrance image will be referred to as the "gate photographing time."

[0037] 2. Input information management system Next, the driving information management system of the present invention will be described in detail. Figure 2 is a block diagram showing the main components of the driving information management system 100 of the present invention. As shown in this figure, the driving information management system 100 of the present invention is configured to include a driving site photographing means 101, a field vehicle information reading means 102, a specification information reading means 103, and a sequential driving information generating means 104, and can also be configured to include a gate entrance photographing means 105, a gate vehicle information reading means 106, a transport vehicle status determining means 107, a driving time determining means 108, a guide display means 109, an excess warning information control means 110, an excess warning information output means 111, a warning information control means 112, a warning information output means 113, a sequential driving information storage means 114, and a field vehicle information storage means 115.

[0038] Of the main elements constituting the driving information management system 100, the field vehicle information reading means 102, specification information reading means 103, sequential driving information generating means 104, gate vehicle information reading means 106, transport vehicle status determining means 107, driving time determining means 108, excess warning information control means 110, and attention calling information control means 112 can be manufactured as dedicated devices or general-purpose computer devices can be used. This computer device is equipped with a processor such as a CPU, memory such as ROM and RAM, input means such as a mouse and keyboard, and a display, and executes calculations according to a predetermined program, and can be configured as a personal computer (PC), a server, a tablet PC such as an iPad (registered trademark), a mobile terminal including a smartphone, etc.

[0039] The sequential input information storage means 114 and the field vehicle information storage means 115 can be configured as a general-purpose computer storage device or as a database server. When configured as a database server, it can be placed on a local network (LAN: Local Area Network) or as a cloud server that stores data via the Internet.

[0040] The components of the pouring information management system 100 can be distributed among the concrete pouring site, the vicinity of the entrance gate GT, and the management team, as shown in Figure 3. In this figure, the pouring site photographing means 101, the site vehicle information reading means 102, the transport vehicle status determination means 107, the specification information reading means 103 (particularly the delivery note photographing means described below), the excess warning information output means 111, and the attention information output means 113 are located at the concrete pouring site, the gate entry photographing means 105, the gate vehicle information reading means 106, and the guide display means 109 are located near the entrance gate GT, and the sequential pouring information generating means 104, the pouring time determining means 108, the excess warning information control means 110, and the attention information control means 112 are located in the management team. The management team can be located in a location different from the concrete pouring site and the entrance gate GT, and can be located within the construction yard YD or away from the construction yard YD.

[0041] The pouring site photographing means 101, the site vehicle information reading means 102, and the transport vehicle status determination means 107 are preferably located at a location at the concrete pouring site slightly away from the transport vehicle AG (a location where it is easy to photograph the transport vehicle AG), while the specification information reading means 103 (particularly the delivery note photographing means described below), the excess warning information output means 111, and the attention information output means 113 are preferably located at a location at the concrete pouring site closer to the transport vehicle AG. In this case, the site vehicle information reading means 102 and the transport vehicle status determination means 107 can utilize a computer device located slightly away from the transport vehicle AG, and the specification information reading means 103 can utilize a computer device located close to the transport vehicle AG. Similarly, the gate vehicle information reading means 106 can utilize a computer device located near the entrance GT, and the sequential pouring information generating means 104, the pouring time determining means 108, the excess warning information control means 110, and the attention information control means 112 can utilize computers located in the management team. As shown in FIG. 3, the computers are configured to be able to transmit and receive information to and from each other via wireless communication means (or wired communication means).

[0042] Below, each of the main elements that make up the drive-in information management system 100 of the present invention will be described in detail.

[0043] (Method of photographing the installation site) As mentioned above, the pouring site photographing means 101 is installed at each concrete pouring site and acquires "pouring site images." The pouring site images acquired by the pouring site photographing means 101 are recorded with the time the site was photographed. The pouring site photographing means 101 is used as a so-called fixed camera and is installed so that pouring site images with approximately the same angle of view (photographing range, photographing direction, zoom, etc.) are acquired. Furthermore, it is preferable to use a pouring site photographing means 101 that allows the angle of view to be adjusted by remote control by an operator. When acquiring pouring site images, the angle of view is adjusted to a predetermined value, and when there is no need to acquire pouring site images, the angle of view is adjusted while monitoring the site.

[0044] FIG. 4 is a model diagram that shows a schematic representation of a pouring site image acquired by the pouring site photographing means 101. As shown in this figure, the pouring site image is acquired so as to include the transport vehicle AG, in particular the license plate. However, at this time, the transport vehicle AG is positioned in a predetermined location (hereinafter referred to as the "regular pouring position") for pouring concrete, for example, a transport vehicle AG positioned in a location (regular pouring position) close to a concrete pump truck. The pouring site image acquired here is stored in the site vehicle information storage means 115 (FIG. 2).

[0045] (Field vehicle information reading means) The on-site vehicle information reading means 102 is a means for reading the "vehicle number information (part or all of the vehicle registration plate)" of the transport vehicle AG contained in the driving site image by performing image recognition on the driving site image. Various conventional image analysis techniques can be used to read the vehicle number information from the driving site image, and for example, machine learning technology can be used to automatically extract the vehicle number information. When using machine learning technology, the vehicle number information is automatically extracted by inputting the driving site image into a "trained model." This trained model can be generated by machine learning a large amount of training data, using driving site images with vehicle number information attached as "training data."

[0046] The vehicle number information obtained by the on-site vehicle information reading means 102 is stored in the on-site vehicle information storage means 115 (FIG. 2). At this time, it is preferable to store it as a "on-site vehicle information table" as shown in FIG. 5. That is, the vehicle number information, the driving site image ID (an identifier that identifies the driving site image), and the on-site photographing time are associated with each other; in other words, the vehicle number information, the driving site image ID, and the on-site photographing time are treated as one record, and a on-site vehicle information table consisting of multiple records is formed and stored in the on-site vehicle information storage means 115. As shown in FIG. 5, the on-site photographing time at which the driving site image of the guided vehicle AG deployed at the fixed driving position was first acquired is specifically referred to as the "on-site photographing start time." However, this on-site photographing start time is assigned to each delivery; that is, if the same guided vehicle AG is deployed more than once, different on-site photographing start times are assigned to each.

[0047] (Specification information reading means) The specification information reading means 103 is a means for reading the concrete specification information written on the "delivery note" as a paper medium and generating the read concrete specification information as text data (hereinafter referred to as "specification text data"), and is composed of a delivery note photographing means and a text data conversion means. Here, text data is a record created in an electronic, magnetic or other format that cannot be recognized by human perception, and includes electromagnetic records used for information processing by a computer, and is data mainly composed of numbers, letters, symbols, etc.

[0048] To read concrete specification information from a delivery slip, first, image data of the delivery slip is acquired using a delivery slip photographing device. This delivery slip photographing device can be any of a variety of conventional devices, such as a digital camera, smartphone, tablet PC, or image scanner. Figure 6 is a model diagram showing an example of scanning a delivery slip using a mobile device such as a tablet PC or smartphone. In this case, the scanning application stored on the mobile device guides the user through the necessary operations. It is anticipated that the delivery slip scanning operation will also be performed by the driver of the transport vehicle AG, so it is desirable to have a specification that allows for easy operation, as in the example in Figure 6. To further simplify the operation, it is also possible to attach an "external button" that allows the driver to confirm the operation feel, or to add a "voice guidance function."

[0049] The image data of the delivery note captured by the delivery note photographing means is transmitted to the text data conversion means. The text data conversion means then generates specification text data from the image data. This text data conversion means can utilize various conventional technologies, including OCR (Optical Character Recognition / Reader), and it is also possible to generate specification text data using, for example, machine learning technology. When machine learning technology is used, the specification text data is generated by inputting the image data into a "trained model." This trained model can be generated by machine learning a large amount of training data, with the image data annotated with the specification text data being used as "training data."

[0050] When the present invention targets a delivery slip containing a two-dimensional code, it is possible to design the device to read only the two-dimensional code without acquiring the image data of the entire delivery slip. However, the two-dimensional code is a two-dimensional graphic pattern converted from information such as letters and numbers (i.e., concrete specification information) written on the delivery slip, such as a QR Code (registered trademark). Alternatively, a one-dimensional code such as a barcode can be used instead of the two-dimensional code. In this case, the delivery slip photographing means can be a conventionally used device for reading two-dimensional (or one-dimensional) codes, and the text data conversion means can be a conventionally used device for converting two-dimensional (or one-dimensional) codes. Furthermore, when the specification text data is managed on a web server, it is also possible to design the device to reference the web server using URL information obtained from the two-dimensional code, etc., and read the specification text data stored there.

[0051] Incidentally, although it has been explained that the specification information reading means 103 can be placed at the concrete pouring site, it is also possible to place both the delivery note photographing means and the text data conversion means at the concrete pouring site, or to place only the delivery note photographing means at the concrete pouring site. When only the delivery note photographing means is placed, the text data conversion means can use a computer device placed in a remote location such as an administration building or supervisor's office, or it can use an external service that returns text data when image data is sent.

[0052] When the specification information reading means 103 generates the specification text data, it generates a "specification information table" as shown in Fig. 7. This specification information table is made up of multiple records, with one record consisting of transport vehicle identification information and specification text data (in this figure, the mixing start time and the amount of fresh concrete). In the example in this figure, the combination of the concrete shipping plant and the agitator vehicle number is used as the "transport vehicle identification information," but this is not limiting, and if the agitator vehicle number alone can be used to identify the transport vehicle from other vehicles (i.e., it is unique), the agitator vehicle number can also be used as the "transport vehicle identification information."

[0053] (Sequential input information generating means) The sequential placing information generating means 104 is a means for generating "sequential placing information" which is a set of "vehicle number information" and "specification text data." Specifically, the sequential placing information generating means 104 reads out the vehicle number information and specification text data relating to the same transport vehicle AG (same transport), and generates a "sequential placing information table" as shown in Figure 8. This sequential placing information table is formed by a plurality of records, with sequential placing information consisting of vehicle number information and specification text data (in this figure, the mixing start time and the amount of fresh concrete) being treated as one record.

[0054] To generate the sequential input information, in other words, to associate vehicle number information with specification text data, a "vehicle correspondence table" is used. This vehicle correspondence table is set in advance, and as shown in FIG. 9, vehicle number information and vehicle identification information are associated with each other. That is, by referring to the vehicle correspondence table, vehicle number information and vehicle identification information are associated with each other, and as a result, specification text data related to the vehicle identification information can be associated with the vehicle number information. The sequential input information generated here is stored in the sequential input information storage means 114 (FIG. 2).

[0055] (Gate entrance photography method) As described above, the gate entrance photographing means 105 is installed near the entrance GT and captures "gate entrance images" of the transport vehicle AG entering through the entrance GT. The gate entrance images captured by the gate entrance photographing means 105 record the time the gate was photographed. The gate entrance photographing means 105 is used as a so-called fixed camera and is installed so that gate entrance images with approximately the same angle of view are captured. Furthermore, it is preferable to use a gate entrance photographing means 105 that allows the angle of view to be adjusted by remote control by an operator. When capturing gate entrance images, the angle of view is adjusted to a predetermined value, and when it is not necessary to capture gate entrance images, the angle of view is adjusted while monitoring the site.

[0056] (Gate vehicle information reading means) The gate vehicle information reading means 106 is a means for reading the "vehicle number information" of the transport vehicle AG contained in the gate entrance image by performing image recognition on the gate entrance image. As with the on-site vehicle information reading means 102, various conventional image analysis techniques can be used to read the vehicle number information from the gate entrance image. For example, machine learning techniques can be used to automatically extract the vehicle number information. When using machine learning techniques, the vehicle number information is automatically extracted by inputting the gate entrance image into a "trained model." This trained model can be generated by machine learning a large amount of training data, using gate entrance images with vehicle number information attached as "training data."

[0057] Using the vehicle number information obtained by the gate vehicle information reading means 106, a "gate vehicle table" such as that shown in FIG. 10 can be created. That is, the vehicle number information, the gate entry image ID (an identifier for identifying the gate entry image), and the gate photographing time are associated with each other. In other words, the gate vehicle table is formed from multiple records, each consisting of vehicle number information, gate entry image ID, and gate photographing time. In this case, the sequential entry information generating means 104 can generate sequential entry information including the gate photographing time. Specifically, the sequential entry information generating means 104 references the gate vehicle table to extract the gate photographing time associated with a specific vehicle number, obtain sequential entry information associated with the same vehicle number, and include the gate photographing time in the sequential entry information. By managing the gate photographing time as the pouring information, it is possible to clarify who is responsible when the transport vehicle AG arrives late at the concrete pouring site. In other words, if the transport vehicle AG entered the construction yard YD at the designated time but was asked to wait within the construction yard YD, the concrete shipping factory would not be held responsible, but if the time the transport vehicle AG passed through the entrance gate GT (i.e., the time the gate was photographed) was delayed in the first place, the concrete shipping factory would be held responsible.

[0058] (Transportation vehicle state determination means) The vehicle status determination means 107 is a means for determining whether the vehicle AG is positioned at the "regular pouring position" (hereinafter referred to as the "vehicle positioned state") or whether the vehicle AG has left the "concrete pouring site" (hereinafter referred to as the "vehicle left state") based on the vehicle number information related to the pouring site image. As mentioned above, the pouring site photographing means 101 captures images as video or continuous still images, so pouring site images are acquired at extremely short time intervals. Therefore, the vehicle status determination means 107 repeatedly determines the state of the vehicle AG (vehicle positioned state / vehicle left state). The determination can be made each time a pouring site image is acquired, or at regular intervals (for example, every 1 second). The following describes the processing procedure used by the vehicle status determination means 107 to determine the state of the vehicle AG.

[0059] The vehicle status determination means 107 determines the status of the vehicle AG (hereinafter simply referred to as "status determination") based on the vehicle number information associated with the driving site image. This status determination is repeated as described above. Specifically, when performing the status determination, the vehicle number information is received from the on-site vehicle information reading means 102. If the vehicle number information associated with the previous status determination matches the vehicle number information associated with the current status determination, the vehicle status determination means 107 determines the vehicle as "in service." Alternatively, the vehicle status determination means 107 may use various conventional image analysis techniques to generate the license plate shape (e.g., a rectangle generated from the four corner points), and if the previous and current vehicle number information match and the previous and current license plate shapes overlap to a certain extent (e.g., 10% or more of the area), it determines the vehicle as "in service." Furthermore, the vehicle status determination means 107 determines the vehicle as "leaving" when the vehicle number information associated with the previous status determination does not match the vehicle number information associated with the current status determination. Furthermore, if the vehicle number information matches between the previous and current events, but the shapes of the license plates do not overlap to a certain extent (for example, 10% or more of the area), the system can be configured to determine that the vehicle has left the area.

[0060] As explained above, the vehicle status determination means 107 repeatedly performs status determination, determining whether the vehicle is in the deployed state or the vehicle has left state each time. Therefore, the results may be unstable, such as when the vehicle is repeatedly determined to be in the deployed state and the vehicle has left state, and in some cases, the vehicle may be determined to be in the left state even when it is actually in the deployed state. Therefore, it is possible to immediately determine the vehicle as in the deployed state when the vehicle number information matches even once (and the license plate shapes overlap), and immediately determine the vehicle as the left state when the vehicle number information does not match even once. Alternatively, it is also possible to determine the vehicle as in the deployed state or the vehicle has left state only when certain conditions are met.

[0061] For example, the vehicle may be determined to be in a deployed state when the number of times the same vehicle number information is read consecutively (i.e., the number of times the vehicle number information matches) exceeds (or becomes equal to) a predetermined threshold (hereinafter referred to as a "continuous deployment threshold"). Alternatively, the vehicle may be determined to be in a deactivated state when the number of times the same vehicle number information is read consecutively falls below (or becomes equal to) a predetermined threshold (hereinafter referred to as a "continuous exit threshold"). In the example of FIG. 11, the continuous deployment threshold is set to 30 times, and the continuous exit threshold is set to 20 times. Therefore, the vehicle state determination means 107 in this case determines the vehicle as in a deployed state at determination time T32, and determines the vehicle as deactivated state at determination time T88.

[0062] Alternatively, the vehicle may be determined to be in a deployed state when the number of times the same vehicle number is read (i.e., the number of times the vehicle number information matches) among a predetermined number of times (hereinafter referred to as the "deployment determination count") exceeds (or becomes equal to) a predetermined threshold (hereinafter referred to as the "deployment ratio threshold"). Alternatively, the vehicle may be determined to be in a exited state when the number of times the same vehicle number is read among a predetermined number of times (hereinafter referred to as the "exit determination count") falls below (or becomes equal to) the predetermined threshold (hereinafter referred to as the "exit ratio threshold"). For example, if the deployment determination count is 50 times and the deployment ratio threshold is 40 times, the vehicle is determined to be in a deployed state if the number of times the vehicle number information matches is 45 times. Similarly, if the exit determination count is 30 times and the exit ratio threshold is 10 times, the vehicle is determined to be in an exited state if the number of times the vehicle number information matches is 8 times.

[0063] (Entering time determining means) The pouring time determination means 108 determines the time when the transport vehicle AG begins to participate in pouring concrete (hereinafter referred to as the "pouring start time") and the time when the transport vehicle AG ceases to participate in pouring concrete (hereinafter referred to as the "pouring end time"). It determines the pouring start time and pouring end time based on the time when the status of the transport vehicle AG is determined (hereinafter referred to as the "determination time"). Since the pouring time determination means 108 performs processing based on the determination time of the transport vehicle status determination means 107, it repeatedly determines the pouring start time and pouring end time. Therefore, the results may be unstable, such as the pouring start time and pouring end time being determined repeatedly and frequently. Therefore, it is possible to determine the pouring start time immediately when the transport vehicle is determined to be in the deployed state even once, and the pouring end time immediately when the transport vehicle is determined to be in the exited state even once. Alternatively, it is also possible to determine the pouring start time and pouring end time only when certain conditions are met. The following describes the processing steps performed by the input time determination means 108 to determine the input start time and input end time.

[0064] FIG. 12 is a model diagram for explaining the processing procedure for determining the pouring start time and pouring end time. As shown in this diagram, if a person or worker enters between the pouring site photographing means 101 and the guided vehicle AG, the pouring site photographing means 101 is blocked, and the guided vehicle status determination means 107 determines that the guided vehicle is in the withdrawn state, even if the guided vehicle is actually in the deployed state. On the other hand, when the guided vehicle AG leaves the concrete pouring site, it returns to the concrete shipping plant, so a certain period (hereinafter referred to as the "determination period") must pass before the same guided vehicle AG is deployed to the same designated pouring position (concrete pump truck). Therefore, by utilizing this determination period, the pouring start time and pouring end time can be appropriately determined. Specifically, if no other judgments have been made regarding the same transport vehicle AG within the period going back by the "judgment period" from the judgment time when the transport vehicle was placed (hereinafter, for convenience, referred to as the "pre-elapsed period"), that judgment time is determined as the start time of the entry, and if no other judgments have been made regarding the same transport vehicle AG within the period of the "judgment period" that has passed since the judgment time when the transport vehicle was placed (hereinafter, for convenience, referred to as the "post-elapsed period"), that judgment time is determined as the end time of the entry.

[0065] For example, in Figure 12, the judgment period is set to 60 minutes, and the start and end times of the drive are determined based on this judgment time (60 minutes). For example, in record No. 03, the drive is judged as being in a vehicle-deployed state, but since the judgment of record No. 02 occurred within the preceding elapsed period (1 minute earlier), the drive start time is not determined by record No. 03. In contrast, in record No. 07, the drive is judged as being in a vehicle-deployed state, and the judgment of the immediately preceding record No. 06 occurred 78 minutes earlier, meaning that there are no other judgments within the preceding elapsed period, so the judgment time (13:24) for record No. 07 is determined as the drive start time. In addition, the system can be designed so that the specified judgment time is determined as the start time of input (e.g., 13:24) as is, or the system can be designed so that the time that is a specified amount of time (e.g., 5 minutes) before the specified judgment time (e.g., 13:24 - 5 minutes) or the time that has passed (e.g., 13:24 + 5 minutes) is determined as the start time of input (in this case, 13:19 or 13:29).

[0066] Furthermore, although record No. 08 indicates that the transport vehicle has left the vehicle, the determination of record No. 09 occurs within the subsequent elapsed time (one minute later), and therefore the end time of the input is not determined by record No. 08. In contrast, record No. 10 indicates that the transport vehicle has left the vehicle, and the determination of the immediately following record No. 11 occurs 70 minutes later. In other words, since there are no other determinations within the subsequent elapsed time, the determination time (13:32) for record No. 10 is determined as the end time of the input. Note that the specified determination time can be determined as the end time of the input (e.g., 13:32), or a time a specified time (e.g., three minutes) has elapsed from the specified determination time (e.g., 13:32 + 3 minutes) or a time going back (e.g., 13:32 - 3 minutes) can be determined as the end time of the input (in this case, 13:35 or 13:29).

[0067] The sequential entry information generating means 104 can generate sequential entry information including the entry start time and entry end time determined by the entry time determining means 108. Specifically, the sequential entry information generating means 104 acquires car number information related to the entry start time and car number information related to the entry end time, and also acquires sequential entry information related to the same car number information, and includes the entry start time and entry end time in the sequential entry information.

[0068] (Guidance display means) The guide display means 109 is installed near the entrance GT of the construction yard YD and is a means for displaying the designated pouring position (concrete pump truck) to the transport vehicle AG entering the entrance GT, and is implemented, for example, by using an electronic bulletin board or display. The guide display means 109 is particularly effective in cases where two or more concrete pump trucks are arranged within the construction yard YD. In this case, a pouring site photographing means 101 and a site vehicle information reading means 102 are arranged to correspond to each concrete pump truck, and the pouring time determination means 108 determines the pouring start time and pouring end time for each concrete pump truck (i.e., each designated pouring position).

[0069] The guidance display means 109 displays the concrete pump truck to which the driver should head in accordance with the processing of the pouring time determination means 108. Specifically, after the pouring end time is determined by the pouring time determination means 108, a pouring site photographing means 101 for which a pouring start time has not yet been determined is selected, and the concrete pump truck corresponding to that pouring site photographing means 101 is displayed by the guidance display means 109. For example, in FIG. 13, the designated pouring position to the left of the second concrete pump truck PCb is vacant, and therefore the guidance display means 109 displays this second concrete pump truck PCb. This is advantageous because the driver of the transport vehicle AG can head to the desired concrete pump truck (i.e., the designated pouring position) without getting lost.

[0070] (Excess warning information output means) As mentioned above, the Standard Specifications prescribe standard concrete pouring times to ensure the quality of concrete. Therefore, if the concrete pouring time exceeds a predetermined time threshold (hereinafter referred to as the "concrete elapsed time threshold"), it is advisable to issue a warning to that effect at the concrete pouring site. For convenience, the information that warns that fresh concrete has exceeded the concrete elapsed time threshold will be referred to here as "excess warning information."

[0071] The excess warning information control means 110 is a means for controlling the output of excess warning information, and the excess warning information output means 111 is a means for outputting excess warning information in accordance with the control of the excess warning information control means 110. Therefore, it is desirable that the excess warning information output means 111 be placed at the concrete pouring site, and can be, for example, a display that displays letters and symbols, a speaker that outputs sound, or a light that outputs light (for example, a red rotating light).

[0072] The excess warning information control means 110 receives the "specification text data" from the specification information reading means 103, acquires the "mixing start time" from the data, and calculates the transport time for the transport vehicle AG from the mixing start time and the current time. When the transport time exceeds the concrete elapsed time threshold, the excess warning information control means 110 controls to output excess warning information, and in response, the excess warning information output means 111 outputs excess warning information.

[0073] (Warning information output means) As mentioned above, the specification text data constituting the sequential pouring information is generated by acquiring image data of the "delivery note" as a paper medium. This operation is expected to be performed by the driver of the transport vehicle AG. However, if the driver is unfamiliar with the pouring information management system 100 of the present invention, it is possible that he or she may forget to acquire the image data. Therefore, it is advisable to output information (hereinafter referred to as "reading warning information") at the concrete pouring site to warn that the image data acquisition operation has not been performed.

[0074] The warning information control means 112 is a means for controlling the output of the read warning information, and the warning information output means 113 is a means for outputting the read warning information according to the control of the warning information control means 112. Therefore, like the excess warning information output means 111, the warning information output means 113 is desirably placed at the concrete pouring site, and can be, for example, a display that displays characters and symbols, a speaker that outputs sound, or a light that outputs light (for example, a red rotating light).

[0075] The warning information control means 112 receives the "on-site photographing time" from the driving site photographing means 101, acquires the "on-site photographing start time (FIG. 5)" from the on-site photographing start time, and calculates the elapsed time from the on-site photographing start time and the current time. When the elapsed time exceeds a predetermined time threshold (hereinafter referred to as the "read time threshold"), the warning information control means 112 controls to output read warning information, and in response, the warning information output means 113 outputs the read warning information.

[0076] (Example of use) An example of using the input information management system 100 of the present invention will be described with reference to Figure 14. Figure 14 is a flow diagram showing the main processing flow of the input information management system 100 of the present invention, with the central column showing the processing to be performed, the left column showing information necessary for that processing, and the right column showing information resulting from that processing.

[0077] First, when the transport vehicle AG enters the construction yard YD from the entrance GT, the "gate entry image" and its "gate photographing time" are acquired by the gate entry camera (Step 201 in FIG. 14), and the "vehicle number information" of the transport vehicle AG contained in the gate entry image is read by the gate vehicle information reading means 106 (Step 202 in FIG. 14). Next, when the transport vehicle AG is placed in the "fixed driving position," the "driving site image" is acquired by the driving site photographing means 101 (Step 203 in FIG. 14), and the "vehicle number information" of the transport vehicle AG contained in the driving site image is read by the site vehicle information reading means 102 (Step 204 in FIG. 14).

[0078] For example, the driver of the transport vehicle AG operates the delivery note photographing means (specification information reading means 103) to obtain image data of the "delivery note" as a paper medium. Then, the text data conversion means (specification information reading means 103) that receives the image data generates specification text data (Step 205 in FIG. 14).

[0079] Meanwhile, the vehicle status determination means 107 determines the status of the vehicle AG (vehicle deployment status / vehicle exit status) based on the vehicle number information related to the driving site image (Step 206 in FIG. 14), and the driving time determination means 108 determines the "driving start time" and "driving end time" for the vehicle AG (Step 207 in FIG. 14). Then, the sequential driving information generation means 104 generates sequential driving information including the "vehicle number information," "specification text data," "gate photography time," "driving start time," and "driving end time." The sequential driving information generated here is shared with all parties involved, i.e., it can be viewed in real time. Naturally, various lists, graphs, etc. can be generated based on this sequential driving information. [Industrial Applicability]

[0080] The pouring information management system of the present invention can be used in the construction of various concrete structures, including cast-in-place concrete work and the production of precast concrete (so-called site PC) at construction sites. Considering that the present invention provides appropriately managed, so-called high-quality concrete structures, it can be said to be an invention that can be expected to not only be used industrially but also to make a great contribution to society.
