Description

The present invention relates to a fresh concrete test management system.

Conventionally, mechanisms using portable terminal devices have been proposed to support work at construction sites such as construction sites. For example, at a concrete pouring site, the amount of air in a sample taken from fresh concrete is measured using an air meter, and mobile information is collected from the measured air amount, the separately measured mass of the sample, and the mix of the ready-mixed concrete. A technique is known that calculates the unit quantity of ready-mixed concrete using a terminal (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2006-3121

When ready-mixed concrete is delivered to a construction site, an acceptance test is conducted on-site to test the quality of the ready-mixed concrete. In this acceptance test, field workers conduct prescribed tests on the ready-mixed concrete, write the test results by hand on a recording device such as a blackboard, and place the blackboard near the sampled ready-mixed concrete and test equipment. A series of tasks such as taking pictures of the entire area are performed. In such an acceptance test, it is necessary to conduct the test and record the test results in parallel, which is time-consuming and burdens on-site workers. Particularly in the case of inexperienced field workers, there were cases where tests and records were omitted and acceptance tests had to be redone. In addition, the handwriting on the blackboard was so dirty that it was sometimes impossible to check the test results.

Although a method to simplify the recording of test results using a tablet terminal has been proposed, the practice of handwriting test results on a blackboard and taking images is still in practice. For this reason, there has been a need for a method for testing fresh concrete in a simple and accurate manner.

The present invention has been made in consideration of such circumstances, and one of the objects is to provide a ready-mixed concrete test management system that can reduce the burden of work related to test and management of ready-mixed concrete. .

One aspect of the present invention includes a quality control device that performs quality control of ready-mixed concrete, an application program that operates on a terminal device and supports testing at a site where ready-mixed concrete is used, and a quality control device and a terminal. A ready-mixed concrete test management system includes a data management device that can communicate with each of the devices and manages transmission and reception of data between the quality control device and the terminal device, the application program transmitting data to the terminal device. Via the management device, the quality control device acquires site information related to the site registered and the test results are acquired, and an electronic image containing the site information and test results is superimposed on a partial area of the site photo of the site. A fresh concrete test management system that generates a superimposed image, transmits the test result and superimposed image to a data management device, and the quality control device acquires and registers the test result and superimposed image via the data management device. It is.

According to one aspect of the present invention, it is possible to reduce the burden of work related to test management of fresh concrete.

The terminal device 3 is a computer device having at least a communication function, a display function, an input reception function, an imaging function, and a program execution function. The terminal device 3 is an example of a "terminal device."

Concrete quality testing includes, for example, measuring concrete strength, slump, air content, and chloride content. Among these, the strength is measured by taking a test piece of fresh concrete at the construction site S and conducting a compressive strength test after a predetermined period of time (for example, 28 days). The slump, air content, and chloride content are measured at the construction site S on the day of construction in accordance with predetermined standards.

For example, the quality control device 5 is equipped with a quality control system for controlling the quality of ready-mixed concrete, and processes the registration of construction sites and construction schedules to which ready-mixed concrete will be delivered, and the testing schedule of ready-mixed concrete. Performs registration processing, test result registration processing, various report output processing, etc. The quality control device 5 is placed, for example, in a concrete factory F that manufactures ready-mixed concrete. The quality control device 5 is operated by a manager such as a quality manager or a shipping manager of the concrete factory F, for example. The quality control device 5 is, for example, a computer device such as a personal computer or a server device. The quality control device 5 registers field information and formulation data in response to instructions input by a manager via an input interface (not shown).

The management server 7 includes, for example, a storage unit 9. The management server 7 stores the field information D1 and the formulation data D2 transmitted from the quality control device 5 in the storage unit 9. The management server 7 transmits the site information D1 and the combination data D2 stored in the storage unit 9 to the terminal device 3 in response to a request from the terminal device 3. The management server 7 stores the fresh concrete test result D3 and the blackboard superimposed image D4 transmitted from the terminal device 3 in the storage unit 9. The management server 7 transmits the test results D3 and the blackboard superimposed image D4 stored in the storage unit 9 to the quality control device 5. The management server 7 is an example of a "data management device." That is, the management server 7 is capable of communicating with each of the quality control device 5 and the terminal device 3, and manages the transmission and reception of data between the quality control device 5 and the terminal device 3.

The storage unit 9 is an HDD, flash memory, RAM (Random Access Memory), or the like. The storage unit 9 may be a NAS (Network Attached Storage) device that can be accessed by the management server 7 via the network NW.

Each function of the quality control device 5 and the management server 7 is realized by a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of the functions may be realized by hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), GPU (Graphics Processing Unit), etc. , may be realized by cooperation of software and hardware.

[Configuration of terminal device 3 (quality control application A)]
FIG. 2 is a diagram showing an example of functional blocks of the terminal device 3 according to the embodiment. The terminal device 3 includes, for example, a control unit 10, a communication device 20, an input interface 30, a camera 40, a display 50, and a storage unit 60.

The communication device 20 includes, for example, a communication interface such as a NIC (Network Interface Card). The communication device 20 communicates with external devices such as the management server 7 via the network NW.

The input interface 30 receives various input operations from the site worker M, converts the received input operations into electrical signals, and outputs the electrical signals to the control unit 10. The input interface 30 is realized by, for example, a touch panel. If the input interface 30 is a touch panel, the display 50 may be integrated with the input interface 30.

The camera 40 is, for example, a digital camera using a solid-state imaging device such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The camera 40 is provided at least on the back side of the display 50 of the terminal device 3. The field worker M can take a photo while checking the imaging target displayed on the display 50.

The display 50 displays various information. The display 50 displays, for example, an image showing the content processed by the control unit 10, a GUI (Graphical User Interface) for accepting various input operations by the site worker M, and the like. The display 50 is an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence) display, or the like.

The control unit 10 controls the overall operation of the terminal device 3. The control unit 10 includes, for example, an acquisition unit 101, a blackboard image generation unit 103, an imaging control unit 105, a display control unit 107, a registration unit 109, and an editing unit 111. Each functional unit of the control unit 10 is realized, for example, by a hardware processor such as a CPU executing a test management application A (program (software)). Some or all of these components are realized by hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and GPU (Graphics Processing Unit). Alternatively, it may be realized by cooperation of software and hardware. The test management application A may be stored in the storage unit 60 in advance, or may be installed in the storage unit 60 by being downloaded via the Internet. Test management application A is an example of an "application program."

The acquisition unit 101 acquires site information D1 and formulation data D2 from the management server 7 via the communication device 20.

The blackboard image generation unit 103 generates a blackboard image based on the site information D1 and the formulation data D2 acquired by the acquisition unit 101 and the test result D3 input by the site worker M via the input interface 30. . A blackboard image is, for example, an electronic image imitating a blackboard on which writing is performed manually. On the blackboard image, site information D1, combination data D2, and test results D3 are displayed at predetermined locations set for each item.

FIG. 3 is a diagram showing an example of the blackboard image BB according to the embodiment. In the blackboard image BB, for example, "construction name", "constructor", "place of pouring", "name (mixture data)", Information corresponding to items such as "sampling date" is displayed, and "slump", "air content", "chloride content", and "concrete temperature" are displayed based on the test results D3 input by field worker M. Measured values of the corresponding test results are displayed for items such as ``.

The imaging control unit 105 causes the camera 40 to image the object in response to an imaging instruction input by the field worker M via the input interface 30.

The display control unit 107 performs control to display various images on the display 50. The display control unit 107 causes the display 50 to display the blackboard image BB generated by the blackboard image generation unit 103, a GUI for accepting various input operations by the site worker M, and the like. When capturing a site photo after completion of a fresh concrete test, the display control unit 107 superimposes the blackboard image BB generated by the blackboard image generation unit 103 on the site image (site photo) to be imaged. Then, it is displayed on the display 50. The field worker M confirms that the blackboard image BB is superimposed on the imaging target on the display 50 and inputs an imaging instruction via the input interface 30, thereby incorporating the blackboard image BB into the imaging target. A blackboard superimposed image D4 can be generated.

The registration unit 109 transmits the test result D3 and the blackboard superimposed image D4 to the management server 7 via the communication device 20. Thereafter, the test result D3 and the blackboard superimposed image D4 are registered in the quality control device 5 by the management server 7 transmitting the test result D3 and the blackboard superimposed image D4 received from the terminal device 3 to the quality control device 5. .

The editing unit 111 performs editing processing on the site information D1, the combination data D2, the test results D3, and the blackboard image BB generated by the blackboard image generation unit 103 received from the management server 7. The editing process includes changing the numerical value of the test result D3 included in the blackboard image BB before generating the blackboard superimposed image D4, changing the font, and the like. Note that in order to prevent falsification of the test results, editing of the image (blackboard superimposed image D4) once saved is not permitted. A hash value calculated from the image data is recorded in the metadata of the blackboard superimposed image D4 in accordance with a predetermined standard so that it can be detected even if the blackboard superimposed image D4 is edited by another application. That is, the test management application A causes the terminal device 3 to edit the blackboard image BB (electronic image) based on the operation by the field worker M (user) of the terminal device 3. Details of the processing by the editing unit 111 will be described later.

The storage unit 60 is an HDD, flash memory, RAM, or the like. The storage unit 60 may be a NAS device that can be accessed by the terminal device 3 via the network NW. The storage unit 60 stores, for example, information such as a test management application A, test results D3, and a blackboard superimposed image D4.

That is, the test management application A operates on the terminal device 3 and supports testing at a site where ready-mixed concrete is used. The test management application A causes the terminal device 3 to acquire site information related to the site registered in the quality control device 5 via the management server 7, to acquire the test results of the test, and to obtain electronic information including the site information and test results. A superimposed image in which the image is superimposed on a partial area of a photograph of the site is generated, and the test results and the superimposed image are transmitted to the management server 7. The quality control device 5 acquires and registers test results and superimposed images via the management server 7.

The test management application A causes the terminal device 3 to further acquire the mix data of ready-mixed concrete registered in the quality control device 5 via the management server 7, and the electronic image further including the mix data is displayed as part of the site photograph. A superimposed image superimposed on the partial area is generated. The site information includes at least one of a site name, a builder, and a construction schedule, and the test results include at least one measured value of slump, air content, and chloride content of fresh concrete.

[Processing flow of ready-mixed concrete test management system 1]
Next, the processing flow of the fresh concrete test management system 1 will be explained. FIG. 4 is a sequence diagram showing an example of the processing flow of the ready-mixed concrete test management system 1 according to the embodiment. First, in the concrete factory F, site information D1 and mixture data D2 are registered in the quality control device 5 based on instructions from a manager via the input interface (not shown) of the quality control device 5 (step S100). Next, the quality control device 5 transmits (uploads) the registered site information D1 and combination data D2 to the management server 7 (step S101). After this registration work is completed, ready-mixed concrete is delivered from the concrete factory F to the construction site S, for example, by a delivery vehicle such as a mixer truck.

After the ready-mixed concrete arrives at the construction site S, when the site worker M operates the terminal device 3 to launch the test management application A, the acquisition unit 101 of the terminal device 3 acquires the site information D1 and the mixture necessary for the test. A request for data D2 is sent to the management server 7 (step S103). In response to the request for the site information D1 and formulation data D2, the management server 7 transmits the corresponding site information D1 and formulation data D2 to the terminal device 3 (step S105). For example, the acquisition unit 101 sends the request to the management server 7, including identification information such as the user number and personal ID used by the field worker M when logging into the test management application A. The management server 7 extracts site information D1 and combination data D2 that are registered in advance in association with this identification information, and transmits the extracted site information D1 and combination data D2 to the terminal device 3. Regarding step S103 above, the timing of transmitting the request for site information D1 and mixture data D2 from the terminal device 3 to the management server 7 is not limited to after the ready-mixed concrete arrives at the construction site S. If the communication function of the terminal device 3 is limited (for example, only the WiFi function can be used) and Internet communication cannot be performed outside the concrete factory F, the acquisition unit 101 of the terminal device 3 requests the request within the concrete factory F before delivery. may be transmitted to the management server 7 to obtain necessary information in advance.

Next, the display control unit 107 of the terminal device 3 displays a test object selection screen on the display 50 (step 107). FIG. 5 is a diagram illustrating an example of a test subject selection screen according to the embodiment. On this test object selection screen, for example, calendar information P1 and a list of test objects P2 are displayed. The site worker M selects (touches) a site to be tested from among the test targets included in the test target list P2.

Next, the display control unit 107 of the terminal device 3 displays a test details screen on the display 50 in response to the site selection operation on the test object selection screen (step 109). FIG. 6 is a diagram illustrating an example of a test details screen according to the embodiment. In this test details screen, for example, test detailed information P3 of the selected test subject is displayed. The test detailed information P3 includes, for example, in addition to the field information D1 and the formulation data D2, information regarding test conditions such as the sample size and the number of tests in the test.

Next, the display control unit 107 of the terminal device 3 displays a test result input screen on the display 50 in response to an input instruction from the field worker M on the test details screen or the like (step 111). FIG. 7 is a diagram showing an example of a test result input screen according to the embodiment. On this test result input screen, for example, an area (input form) P4 for accepting input of numerical values of the test result D3, etc. is displayed. The field worker M can register the test result D3 by inputting the test result D3 into this input form P4. Furthermore, this test result input screen includes a "take photo" button that accepts instructions to take a photo, a "select photo" button that accepts instructions to select a photo that has already been taken, and an instruction to generate the blackboard superimposed image D4. Buttons P5 are provided, including a "blackboard edit" button and the like.

Note that the slump measurement may be automatically performed using the LiDAR function provided in the terminal device 3, and the measurement results may be obtained. For example, 3D point cloud data of a fresh concrete sample to be tested is acquired using LiDAR, and slump is measured.

Next, the blackboard image generation unit 103 of the terminal device 3 generates a blackboard image BB as shown in FIG. 3 (step S113). Note that the layout of each item on the blackboard image BB can be changed as appropriate according to requests. For example, the layout setting information specified by the site worker M etc. is registered in advance in the test management application A, and the blackboard image generation unit 103 generates the blackboard image BB according to this layout setting information. You can also do this.

Next, the display control unit 107 of the terminal device 3 displays an imaging preparation state screen on the display 50, for example, when the "blackboard edit" button is pressed on the test result input screen shown in FIG. 7 (step 115). FIG. 8 is a diagram illustrating an example of an imaging preparation state screen according to the embodiment. On this imaging preparation state screen, an image P6 (site image) of the target space that is currently a target (candidate) for imaging by the camera 40 of the terminal device 3 is displayed, and a region P7 of the image P6 of the target space is displayed. The blackboard image BB generated by the blackboard image generation unit 103 is displayed in a superimposed manner. The field worker M presses the button P8 that accepts imaging instructions while checking this imaging preparation state screen, so that the imaging control unit 105 outputs the imaging instruction to the camera 40, and the scene where the blackboard image BB is superimposed is outputted to the camera 40. A blackboard superimposed image D4 that is a photograph can be generated. As a result, a blackboard image BB is created from the information of the site information D1 and compounding data D2 obtained in synchronization with the quality control device 5, and the test results D3 registered in the quality control application A by the site worker M. It can be imprinted on the on-site photograph taken by the device 3.

Note that the shape of the blackboard image BB can be any shape other than a rectangle as shown in FIG. For example, the blackboard image BB may have an L-shape. By creating an L-shaped blackboard image BB, the area that hides the on-site photo can be kept at the periphery, thereby avoiding the area close to the center of the on-site photo being hidden by the blackboard image BB. . Further, the position of the blackboard image BB can be changed according to an operation (slide operation) by the site worker M.

Incidentally, the site worker M often places the subject in the center of the remaining rectangular area hidden by the blackboard image BB of the site photo and captures the image. For this reason, if you autofocus at the center of the scene photo, the focus and brightness may not be correct. For this reason, the imaging control unit 105 and the camera 40 may autofocus and image the center of a rectangular area other than the area hidden by the blackboard image BB, instead of the center of the scene photograph. That is, the test management application A causes the terminal device 3 to adjust the focal position according to the position where the electronic image is superimposed and take a photograph of the site.

Even if AR (Augmented Reality) technology is used to display an AR blackboard image that looks like a real blackboard on the imaging preparation state screen, and this AR blackboard image is used to generate the blackboard superimposed image D4. good. Furthermore, using MR (Mixed Reality) goggles, the site worker M may move a virtual blackboard image through the MR goggles and take a photograph of the site as it is visible.

Note that when the "Select photo" button is pressed on the test result input screen shown in FIG. 7 and a desired on-site photo is selected from the captured on-site photos stored in the storage unit 60 of the terminal device 3, For example, the display control unit 107 causes the display 50 to display a screen in which the blackboard image BB generated by the blackboard image generation unit 103 is displayed superimposed on the selected on-site photograph. On this screen, it is possible to change the superimposition position, size, etc. of the blackboard image BB. Furthermore, when the "take photo" button is pressed on the test result input screen shown in FIG. screen) is displayed on the display 50.

Next, the registration unit 109 of the terminal device 3 transmits the test result D3 and the blackboard superimposed image D4 to the management server 7 via the communication device 20 (step S117). The management server 7 transmits the test result D3 and the blackboard superimposed image D4 received from the terminal device 3 to the quality control device 5 (step S119).

Next, the quality control device 5 registers the test result D3 and the blackboard superimposed image D4 received from the management server 7 in the quality control system (step S121). With the above steps, the processing of this flowchart is completed.

In addition, in steps S117, S118, and S121 described above, the registration unit 109 of the terminal device 3 sends the original image of the scene photograph without the blackboard image superimposed to the management server in addition to the test result D3 and the blackboard superimposed image D4. 7, the quality control device 5 may be registered. This allows only the original image to be managed if there is a mistake in the item information included in the blackboard image.

Also, when generating the blackboard superimposed image D4 in step 115 above, information such as site name, test type (slump, air amount, chloride content), etc. is written in metadata (for example, Exif) of the image file. You can also do this. Thereby, the blackboard superimposed image D4 can be searched using the field name, test type, date and time, etc. as keys. Further, the test type may be automatically identified by analyzing the on-site photograph using an AI (Artificial Intelligence) function. For example, a newly acquired on-site photo (or blackboard superimposed image D4) is used for a learning model generated by learning training data in which test type information is associated with an on-site photo (or blackboard superimposed image D4). By inputting D4), the test type may be automatically identified. For example, the terminal device 3 stores the learning model generated in this way in the storage unit 60, and inputs the on-site photograph (or blackboard superimposed image D4) taken by the camera 40 into the learning model. It may be possible to automatically identify the type. Alternatively, the management server 7 stores the learning model generated in this way in the storage unit 9, and inputs the on-site photograph (or blackboard superimposed image D4) received from the terminal device 3 into the learning model to perform the test. The type may be automatically identified and tagged.

That is, the blackboard superimposed image D4 (superimposed image) is given metadata including at least one of information such as site information, test type, and test date and time, and the quality control device 5 Search for superimposed images based on metadata. In addition, the test management application A causes the terminal device 3 to automatically identify the type of test by analyzing the on-site photo using the artificial intelligence function, and the electronic image containing the identified test type is added to the on-site photo. A superimposed superimposed image is generated. Furthermore, the management server 7 uses an artificial intelligence function to automatically identify the type of test by analyzing the on-site photograph or superimposed image received from the terminal device 3.

(editing function)
Next, the editing function of the terminal device 3 will be explained. The terminal device 3 includes an editing section 111 that has a function of editing the site information D1, the combination data D2, the registered test results D3, and the blackboard image BB received from the management server 7. FIG. 9 is a diagram showing an example of the site information editing screen according to the embodiment. On this site information editing screen, an area (input form) P9 is displayed that accepts inputs for changing the contents of each item of the site information D1 and combination data D2. By operating the site information editing screen, the site worker M can change the site information D1 and the combination data D2 at any timing before or after the test.

FIG. 10 is a diagram illustrating an example of a test result editing screen according to the embodiment. This test result editing screen displays an area (input form) P10 that accepts input for changing the contents of each item of the registered test result D3. The field worker M can change the test result D3 at any timing after the test by operating this test result editing screen.

Furthermore, the editing unit 111 can change the numerical values, fonts, etc. of each item of the blackboard image BB before generating the blackboard superimposed image D4. By allowing the font of numerical display items to be changed, it is possible to cope with a situation where, when printing the blackboard superimposed image D4 for a report, the numerical values are crushed and difficult to read.

In addition, in accordance with the above-mentioned changes to the site information D1, compounding data D2, and test results D3, the registration unit 109 stores the changed site information D1, compounding data D2, and test results D3 on the management server 7. The information is transmitted to the quality control device 5 via the host computer. Thereby, it is possible to reflect the changed site information D1, combination data D2, and test results D3 also on the quality control system side managed by the quality control device 5.

According to the embodiment described above, it is possible to reduce the burden of work related to test management of fresh concrete. In particular, the conventional work of handwriting test results on a blackboard can be saved, and at the same time, the test results D3 and the blackboard superimposed image D4 can be simply and accurately registered in the quality control device 5. In addition, this allows the various data registered in the quality control device 5 (field information D1, formulation data D2, test results D3, blackboard superimposed image D4) to be constantly synchronized with the various data stored in the terminal device 3. can be done.

Although the mode for implementing the present invention has been described above using embodiments, the present invention is not limited to these embodiments in any way, and various modifications and substitutions can be made without departing from the gist of the present invention. can be added.
