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.

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 supplies the transported ready-mixed concrete to the pump truck 150 after the agitator vehicle 140, which transports the ready-mixed concrete manufactured at the ready-mixed concrete manufacturing factory to the concrete construction site 160, arrives at the construction site 160. This is a device for managing the actual driving.

<Input management>
First, with reference to FIGS. 1A and 1B, unloading management of ready-mixed concrete at the construction site 160 will be described. The agitator vehicle 140 loaded with ready-mixed concrete manufactured at the ready-mixed concrete manufacturing factory 130 departs 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.

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 (the same number) 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, it can be determined that the agitator car 140 is in the process of unloading. I can judge.

Therefore, as described above, if the same number is continuously extracted between the recorded unloading start time and unloading end time, the concrete placement management device 100 uses this time as the unloading time. , and are recorded in association with the number of the agitator vehicle 140. In this way, since the concrete placement management device 100 records the unloading start time, unloading time, and unloading end time, it is possible to consistently manage a series of operations from the start of unloading to the end of unloading at the construction site 160. I can do it.

Furthermore, during unloading of fresh concrete from the agitator vehicle 140, workers at the construction site 160 may block the license plate 170 due to work circumstances, making it impossible for the camera 195 to capture an image of the license plate 170. be.

In such a case, even if the condition in which the number cannot be extracted from the captured video occurs for a certain period of time, the concrete placement management device 100 can extract the same number again after the certain period of time has elapsed. It is determined that unloading work is continuing. That is, even if there is a certain period of time during which the number of the license plate 170 cannot be extracted, the concrete placement management device 100 continues unloading work from the same agitator vehicle 140 as long as predetermined conditions are met. I judge that.

<Transportation management>
Next, transportation management of ready-mixed concrete at the time of shipment from a manufacturing factory will be explained. 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, an employee of the manufacturing plant 130, or the like using a camera 190 installed on a tablet terminal. A standard camera may also be used.

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 on 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.

Next, the configuration of the concrete placement management device will be described with reference to FIG. 2. The concrete placement management device 100 includes an imaging section 201, an identification number extraction section 202, a start time recording section 203, an end time recording section 204, and an unloading time recording section 205. With these configurations, input management is performed. Further, the concrete placement management device 100 includes an acquisition section 206, a reading section 207, and a recording section 208. Transportation management is performed by these configurations.

The imaging unit 201 is attached to the pump truck 150 or placed near the pump truck 150 in order to image the agitator truck 140 , moves backward to approach the pump truck 150 , and approaches the pump truck 150 in the vicinity of the pump truck 150 . An image of the back of the stopped agitator vehicle 140 is taken.

Here, the camera 195 as the imaging unit 201 is attached to the outrigger of the pump truck 150, for example. 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 near the pump truck 150 or at any position on the construction site 160. If the camera 195 is installed near the pump car 150 or the pump car 150, the correspondence between the agitator car 140 and the pump car 150 to which fresh concrete is supplied becomes clear. Furthermore, the number of cameras 195 installed may be one or more. Furthermore, when the number of cameras 195 installed is one, one camera 195 may take images of two or more agitator cars 140. If two or more cameras 195 are installed and two or more agitator cars 140 are installed, each of the two or more cameras 195 images each of the two or more agitator cars 140. Good too.

The identification number extraction unit 202 extracts an identification number for identifying the agitator vehicle 140 from the video imaged by the imaging unit 201. Further, the identification number extraction unit 202 starts extracting the identification number at the timing when the back of the agitator vehicle 140 falls within the imaging range of the camera 195. In other words, if the back of the agitator vehicle 140 approaching in reverse is not included in the frame of the camera 195, the agitator vehicle 140 will not be captured in the image captured by the camera 195, so the identification number cannot be extracted. I can't. Therefore, the identification number extraction unit 202 starts extracting the identification number at the timing when the agitator vehicle 140 enters the frame of the camera 195. Note that the timing at which the identification number extraction unit 202 starts extracting the identification number is not limited to the timing shown here, but may be, for example, at the timing when the movement of the agitator vehicle 140 in the video imaged by the camera 195 has stopped. There may be.

Here, the identification number extraction unit 202 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 202 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. , Also, there is a possibility that the numbers may be duplicated. Therefore, the identification number extraction unit 202 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. Note that the combination of the vehicle registration number and vehicle number of the agitator vehicle 140 is registered in advance.

The identification number extraction unit 202 extracts the identification number according to the following procedure. First, the identification number extraction unit 202 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 202 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 202 first specifies the position of the license plate 170.

When the position of the license plate 170 is specified, the identification number extraction unit 202 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).

If the same identification number has been continuously extracted for a predetermined period of time by the identification number extraction unit 202, the start time recording unit 203 sets the unloading start time to the time when the same identification number is extracted for the first time, and records the identification number as the unloading start time. and record it.

Here, the start time recording unit 203 sets a condition for recording the unloading start time when the same identification number is continuously extracted for a predetermined period of time. Such conditions are set because, for example, when the agitator car 140 just crosses in front of the camera 195, the license plate 170 of the agitator car 140 will be reflected in the camera 195 for a short time, and the agitator car 140 will be identification number may be extracted. However, in such a case, the agitator car 140 has not approached the pump car 150 for unloading, so the unloading operation is not started. Therefore, if the start time recording unit 203 records the start time of unloading, it will record erroneous data, so it is necessary to eliminate the recording of erroneous data. Therefore, in the start time recording unit 203, the condition for recording the unloading start time is that the same number is continuously extracted for a predetermined period of time.

Therefore, in order to prevent such erroneous recording from occurring, the start time recording unit 203 confirms that the identification number of the agitator car 140 has been continuously extracted for a predetermined period of time, and then extracts the identification number of the agitator car 140. The time when the identification number 140 is extracted for the first time is recorded as the unloading start time. Thereby, the start time recording unit 203 can accurately and reliably record the unloading start time of ready-mixed concrete.

Note that the agitator vehicle 140 transports the ready-mixed concrete produced at the manufacturing factory to the construction site 160, but at the stage of concrete pouring planning, the agitator vehicle 140 transports the ready-mixed concrete to the construction site 160. Not yet. When the agitator car 140 arrives at the construction site 160, the driver of the agitator car 140 follows the instructions of the guide who guides the pump car 150 at which pouring location in the construction site 160 to unload the cargo. , to the designated pump truck 150.

If the same identification number is not extracted continuously for a predetermined period of time by the identification number extraction unit 202, the end time recording unit 204 sets the unloading end time as the time when the same identification number is not extracted for the first time, and records the identification number. and record it. That is, since the agitator car 140 is parked near the pump car 150 during the unloading operation, the back of the agitator car 140 is placed in the frame of the camera 195. Then, the same identification number is continuously extracted by the identification number extraction unit 202.

However, when the unloading work is completed and the agitator car 140 leaves the pump car 150, the agitator car 140 moves out of the frame of the camera 195. Therefore, the identification number extracting unit 202 will no longer extract the same identification number that was extracted during the unloading operation. If such a state continues for a predetermined period of time, it can be determined that the unloading work has already been completed, so the end time recording unit 204 records whether the same identification number that was extracted during the unloading work is extracted first. The timing at which unloading is stopped is recorded as the end time of unloading work in association with the identification number.

If the same identification number is continuously extracted between the unloading start time and the unloading end time, the unloading time recording unit 205 records the time between the unloading start time and the unloading end time as the unloading time. The time is recorded in association with the identification number.

In other words, if the same identification number is continuously extracted by the identification number extraction unit 202, the unloading time recording unit 205 determines that the unloading work of the agitator vehicle 140 having the identification number is continuing. do. Then, while the identification number of the agitator vehicle 140 currently undergoing unloading work continues to be extracted, the unloading time recording unit 205 records the time when the identification number is first extracted and the time when it is last extracted. The time between is recorded as the time during unloading work.

For example, the agitator car 140 is set next to the pump car 150, unloading work is started, and the agitator car 140 continues to stop at that location until the entire amount of transported fresh concrete is transferred to the pump car 150. . Therefore, while the agitator car 140 is being unloaded, the number of the agitator car 140 continues to be extracted. Therefore, while the same number is being extracted continuously, it is assumed that unloading work is being performed, and the unloading time recording unit 205 records the continuously extracted time as being unloading work in progress.

In addition, the unloading time recording unit 205 records a state in which the same identification number is continuously extracted between the unloading start time and the unloading end time, and the same identification number is not extracted for a certain period of time. In the case where the same identification number is continuously extracted after that, the items between the unloading start time and the unloading end time are recorded as the unloading time in association with the identification number.

For example, the driver of the agitator vehicle 140 or the worker at the construction site 160 stands in front of the license plate 170 to perform work, and the license plate 170, which was housed in the frame of the camera 195, becomes hidden. In such a state, the identification number extraction unit 202 will no longer be able to extract the identification number, but if the worker or the like moves from in front of the license plate 170, the identification number extraction unit 202 will extract the identification number again. You will be able to extract the number. In such a case, if the unloading operation is judged to have ended when the identification number can no longer be extracted, an incorrect unloading end time may be recorded even though the unloading operation is actually continuing. I will do it.

Therefore, even if there is a time during the unloading operation when the identification number extraction unit 202 cannot extract the same identification number, the unloading time recording unit 205 can extract the same identification number again after that. If so, it is determined that unloading work is in progress.

By making such a determination, the unloading time recording unit 205 can more accurately and without error determine that the unloading work is continuing. Note that the certain period of time may be from several seconds to several tens of seconds or several minutes, and can be set as appropriate depending on the work procedures and flow line settings at the construction site 160.

The acquisition unit 206 acquires image data 191 of the slip 120 that is generated by reading the slip 120 used when transporting the ready-mixed concrete to the construction site 160 using an imaging device when the ready-mixed concrete is shipped. 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 206 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 207 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 207 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 207 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 208 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 207 because the written contents of the slip 120 are unclear or the written position is shifted, the recording unit 208 may perform the following processing. That is, the recording unit 208 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.

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 time 315, and extraction intermittent time 316 in association with image data ID (Identifier) 311. The image data ID 311 is an identifier for identifying the image data 191 of the slip 120 captured by the camera 190. The image data information 312 is information regarding the imaging conditions of the slip 120, the imaging time, and the like.

The read content data 313 is data about the content read from the image data 191 of the slip 120 by OCR processing, and includes the vehicle number, shipping time, loading amount, and the like. The vehicle registration number 314 is the number of the license plate 170 of the agitator vehicle 140 extracted by the identification number extraction unit 202. The unloading time 315 includes a start time and an end time. The start time is the time when the number of the license plate 170 of the agitator vehicle 140 is extracted for the first time as the start time of unloading. The end time is the time at which the number of the license plate 170 of the agitator vehicle 140 can no longer be extracted as the end time of unloading. The intermittent extraction time 316 is the time during which the number of the license plate 170 of the agitator vehicle 140 could not be extracted, and if this time is within a certain period of time, it indicates that the number is being extracted continuously.

The hardware configuration of the concrete placement management device 100 will be described with reference to FIG. 4. A CPU (Central Processing Unit) 410 is a processor for arithmetic control, and realizes each functional configuration of the concrete placement management device 100 shown in FIG. 2 by executing a program. The CPU 410 has multiple processors and may execute different programs, modules, tasks, threads, etc. in parallel.

In step S533, the reading unit 207 reads the vehicle number of the agitator vehicle 140, the loading amount of ready-mixed concrete, and the shipping time of the ready-mixed concrete written on the slip 120 from the image data 191.

In step S535, the recording unit 208 determines whether the shipping time can be read. If it is determined that the shipping time can be read (YES in step S535), the recording unit 208 proceeds to step S537. In step S507, the recording unit 208 records the read vehicle number, loading amount, and shipping time in association with each other.

If it is determined that the shipping time cannot be read (NO in step S535), the recording unit 208 proceeds to step S539. In step S509, the recording unit 208 records the time when the slip 120 is read by the camera 190, as the ready-mixed concrete shipping time, in association with the vehicle number or the like.
