Description

Technical Field

[0001] The present invention relates to a compaction management system and a compaction management method in concrete compaction work.

Background Art

[0002] Techniques for grasping the compaction state of concrete are known. As an example, Patent Document 1 describes a technique for managing that concrete compaction is reliably performed. In the compaction management described in Patent Document 1, a rod-shaped vibrator is used to compact concrete. The vibrator illustrated in Figure 9 is provided with two transmitters fixed at different heights, and a receiver that receives signals emitted by the transmitters is provided at a location distant from these transmitters. In the compaction management described in Patent Document 1, when the receiver receives signals emitted by both transmitters, it is determined that neither of the two transmitters is buried in the concrete and the vibrator has been pulled out (not inserted) from the concrete. In addition, when the receiver does not receive the signal emitted by the transmitter fixed to the tip side of the vibrator, it is determined that the relevant transmitter and the vibrator are buried in the concrete.

Summary of Invention

Problems to be Solved by the Invention

[0004] In the compaction management described in Patent Document 1, although it is possible to detect that the transmitter fixed to the tip side of the vibrator and the vibrator are buried in the concrete, the depth at which the relevant transmitter and the vibrator are buried in the concrete cannot be detected.

[0005] One aspect of the present invention has been made in view of the above-mentioned problems, and its purpose is to detect the depth to which a vibrator and a transmitter fixed near the vibrator are embedded in concrete, in a situation where the transmitter and vibrator are embedded in concrete. [Means for solving the problem]

[0006] To solve the above problems, the compaction management system according to embodiment 1 of the present invention comprises a rod-shaped vibrating unit for compacting poured concrete, a first transmitter fixed at a position having a predetermined first interval from the tip of the vibrating unit when viewed along the axial direction, a second transmitter fixed at a position having a predetermined second interval from the first transmitter when viewed along the axial direction, a plurality of receivers arranged to surround the concrete pouring area and communicating with each of the first and second transmitters, and a control unit, wherein the control unit is a position identification unit that identifies a first position and a second position, which are the positions of the first and second transmitters, respectively, and identifies the second position according to the results of the second communication when the first communication between each of the plurality of receivers and the first transmitter is interrupted and the second communication between each of the plurality of receivers and the second transmitter is established, and identifies the first position according to the second position and the second interval.

[0007] According to the above configuration, by placing a first transmitter fixed in the concrete at a position having a first interval from the tip of the vibrator, even in situations where the first communication is interrupted and the first position cannot be directly detected, the first position can be identified according to the second position identified according to the communication result of the second communication and the second interval. Therefore, this compaction management system can detect the depth to which the transmitter and vibrator are embedded in the concrete, even when the vibrator and the transmitter fixed near the vibrator are embedded in the concrete.

[0008] In the compaction management system according to aspect 2 of the present invention, in addition to the configuration of the compaction management system according to aspect 1, the plurality of receivers include a plurality of first receivers whose height from the reference plane is a predetermined first height, and a plurality of second receivers whose height from the reference plane is a predetermined second height different from the first height, with a predetermined horizontal plane in the pouring area as the reference plane.

[0009] With the above configuration, the first position can be identified if at least one of the multiple first receivers and the multiple second receivers can establish a second communication. Therefore, compared to the case where only multiple receivers at the same height from the reference plane are used, the first position can be identified even in a concrete pouring area with poor communication conditions.

[0010] Examples of areas with poor communication environments include those where the formwork surrounding the concrete pouring area is set to a high height. In particular, communication environments tend to be poor when structural steel bars are densely packed inside the formwork, when temporary scaffolding is erected inside the formwork, or when steel formwork is used. This compaction management system can be suitably used in such cases as well.

[0011] In the compaction management system according to aspect 3 of the present invention, in addition to the configuration of the compaction management system according to aspect 2, the casting area is defined by a formwork equipped with plate-shaped members surrounding the casting area, the plurality of first receivers are fixed at a predetermined position above the upper end of the formwork, and the plurality of second receivers are fixed at a predetermined position above the lower end and below the upper end of the formwork.

[0012] With the above configuration, the first position can be reliably identified even in areas with poor communication environments during concrete pouring.

[0013] In the compaction management system according to aspect 4 of the present invention, in addition to the configuration of the compaction management system according to aspect 3, the plate-shaped member is made of a dielectric material, and the plurality of second receivers are fixed outside the casting area so as to surround the casting area.

[0014] With the above configuration, since multiple second receivers are fixed outside the concrete pouring area, the placement of the multiple second receivers is not restricted by the concrete pouring sequence or the reinforcement arrangement within the concrete area. Therefore, compared to the case where multiple second receivers are installed inside the concrete pouring area, it is possible to easily position the multiple second receivers at the optimal receiving location.

[0015] In the compaction management system according to aspect 5 of the present invention, in addition to the configuration of the compaction management system according to aspect 3, the plate-shaped member is made of metal, the plurality of second receivers are provided inside the casting area, and the second height is configured to be variable in the vertical direction.

[0016] In the compaction management system according to aspect 6 of the present invention, in addition to the configuration of the compaction management system according to aspect 3, a metal structural member is arranged inside the casting area, the plurality of second receivers are provided inside the casting area, and the second height is configured to be variable in the vertical direction.

[0017] According to the above configuration, the first position can be identified even in concrete pouring areas where the communication environment is particularly poor.

[0018] In the compaction management system according to embodiment 7 of the present invention, in addition to the configuration of the compaction management system according to embodiment 1, the control unit further includes a surface position identification unit that, after continuously inserting and removing the vibrating unit and the first transmitter into the poured concrete, identifies the first position according to the communication result of at least one of the first communication and the second communication at the time when the first communication recovers from interruption, and identifies the identified first position as the surface position of the concrete.

[0019] In the compaction management system according to embodiment 8 of the present invention, in addition to the configuration of the compaction management system according to embodiment 7, the surface position identification unit identifies a first surface position which is the surface position of the first layer of poured concrete after compaction is completed, the position identification unit identifies a first position when the vibrating unit and the first transmitter are inserted into a second layer of concrete poured on top of the first layer, and the control unit further includes an insertion depth identification unit which identifies the insertion depth of the vibrating unit in the first layer according to the first surface position, the first position and the first interval.

[0020] With the above configuration, when compacting the second layer of concrete, which is poured on top of the first layer of concrete that has already been compacted, it is possible to determine whether the vibrator is inserted into the interior of the first layer before compacting the second layer. Therefore, with the above configuration, quantitative control of concrete pouring can be implemented, preventing material segregation and cold joints in the concrete.

[0021] In the compaction management system according to aspect 9 of the present invention, in addition to the configuration of the compaction management system according to aspect 8, the surface position identification unit identifies a second surface position which is the surface position in the second layer after compaction is completed, and the control unit further includes a thickness identification unit which identifies the thickness of the concrete layer in the second layer according to the first surface position and the second surface position.

[0022] According to the above configuration, it is possible to determine whether the thickness of the second layer, which is poured on top of the first layer, is excessive. Therefore, according to the above configuration, quantitative control of concrete pouring can be implemented to prevent material segregation and cold joints in the concrete.

[0023] In the compaction management system according to embodiment 10 of the present invention, in addition to the configuration of the compaction management system according to embodiment 3, each of the plurality of receivers has a communicationable area, and the pouring area is included in a superimposed area where at least two of the communicationable areas overlap.

[0024] According to the above configuration, the unreceivable area of the receiver occupying the placing area can be minimized.

[0025] In order to solve the above problem, a compaction management method according to aspect 11 of the present invention uses a rod-shaped vibrating portion for compacting placed concrete, a first transmitter fixed at a position having a predetermined first interval from the tip of the vibrating portion when viewed along the axial direction, a second transmitter fixed at a position having a predetermined second interval from the first transmitter when viewed along the axial direction, a plurality of receivers arranged so as to surround the concrete placing area and communicating with each of the first transmitter and the second transmitter, and a control unit. The compaction management method for concrete is a position specifying step executed by the control unit to specify a first position and a second position which are the respective positions of the first transmitter and the second transmitter, wherein when first communication between each of the plurality of receivers and the first transmitter is interrupted, and second communication between each of the plurality of receivers and the second transmitter is established, the second position is specified according to the communication result of the second communication, and the position specifying step of specifying the first position according to the second position and the second interval is included.

[0026] According to the above configuration, the same effect as that of aspect 1 is achieved.

Effects of the Invention

[0027] According to one aspect of the present invention, in a situation where a vibrator and a transmitter fixed in the vicinity of the vibrator are buried in concrete, the burial depth of the transmitter and the vibrator in the concrete can be detected.

[0029] [Embodiment 1] The following describes one embodiment of the present invention.

[0030] (Overview of Compaction Management System 0) The compaction management system 0 according to this embodiment is a system for determining the depth to which a vibrator used in concrete compaction work is embedded in concrete.

[0031] (Configuration of Compaction Management System 0) The configuration of the compaction management system 0 will be explained with reference to Figure 1. Figure 1 is a cross-sectional view of concrete and formwork illustrating an example of the configuration of the compaction management system 0. As an example, the compaction management system 0 includes a vibration unit V, a first transmitter 21, a second transmitter 22, a plurality of receivers 3, and an information processing device 1, as shown in Figure 1.

[0032] (Vibrating part V) The vibrating part V is a rod-shaped vibrating part that compacts the poured concrete CO. The vibrating part V may also be a vibrator that compacts the concrete CO by applying vibration to the concrete CO while it is inserted into the poured concrete CO.

[0033] (Transmitter 1, 21) The first transmitter 21 is a transmitter fixed at a position having a predetermined first distance d1 from the tip of the vibrating part V when viewed along the axial direction.

[0034] The first transmitter 21 emits radio waves that can be received by the receiver 3. The radio waves emitted by the first transmitter 21 are blocked by concrete CO. For example, the first transmitter 21 may be fixed to the vibrator. Alternatively, for example, the first transmitter 21 may be fixed near the vibrating unit V, such as on the cable CA connected to the vibrating unit V. Alternatively, for example, the first transmitter 21 may be fixed so as to be integrated with the vibrating unit V, such as by being built into the vibrating unit V.

[0035] The "axial direction" refers to the longitudinal direction of the rod-shaped vibrating part V. For example, the "axial direction" may refer to the longitudinal direction of the vibrating part V and the cable CA connected to the vibrating part V, as shown in Figure 1. Here, for example, the vibrating part V and the cable CA connected to the vibrating part V may be suspended in a substantially vertical direction, as shown in Figure 1. In other words, for example, the "axial direction" may refer to a substantially vertical direction.

[0036] The first interval d1 is a predetermined distance from the tip of the vibrating part V to the position where the first transmitter 21 is fixed, as shown in Figure 1, when viewed along the axial direction.

[0037] (Second transmitter 22) The second transmitter 22 is a transmitter fixed at a position having a predetermined second distance d2 from the first transmitter 21 when viewed along the axial direction.

[0038] The second transmitter 22, like the first transmitter 21, emits radio waves that can be received by the receiver 3. For example, the second transmitter 22 may be fixed on a cable CA connected to the vibrating unit V.

[0039] The second interval d2 is a predetermined distance from the position where the first transmitter 21 is fixed to the position where the second transmitter 22 is fixed, as shown in Figure 1, when viewed along the axial direction.

[0040] The number of second transmitters 22 provided by the compaction management system 0 may be one or more. Here, for example, if the compaction management system 0 is equipped with multiple second transmitters 22, other second transmitters 22 may be fixed at a position further apart by a second distance d2 from a second transmitter 22 that is fixed at a position a predetermined second distance d2 from a first transmitter 21 on the cable CA.

[0041] (Multiple receivers 3) Multiple receivers 3 are arranged to surround the concrete CO pouring area and communicate with the first transmitter 21 and the second transmitter 22, respectively.

[0042] Multiple receivers 3 receive radio waves transmitted by the first transmitter 21 and the second transmitter 22. For example, each of the multiple receivers 3 may use the radio waves transmitted by the first transmitter 21 and the second transmitter 22 to calculate the distance between each of the first transmitter 21 and the second transmitter 22 and the receiver 3. Here, it is preferable that the multiple receivers 3 are, for example, three or more receivers.

[0043] For example, communication between multiple receivers 3 and each of the first and second transmitters 21 and 22 may be conducted using frequencies in the Ultra Wide Band (UWB) spectrum.

[0044] The pouring area is the area where concrete CO is poured. For example, the pouring area may be defined by a formwork F equipped with plate-like members that surround the pouring area. For example, metal structural members may be placed inside the pouring area. As a specific example, metal structural members such as reinforcing bars may be arranged in a grid pattern inside the pouring area, as shown in Figure 1.

[0045] For example, multiple receivers 3 may be fixed in a predetermined position above the lower end of the formwork F. Here, for example, multiple receivers 3 may be fixed to a support column or scaffolding provided at the upper end of the formwork F.

[0046] For example, the position of each of the multiple receivers 3 may be indicated by its height from a predetermined horizontal plane in the casting area, with the horizontal plane in the casting area serving as the reference plane. The "reference plane" is a predetermined horizontal plane in the casting area. For example, the reference plane may be the horizontal plane at the bottom of the formwork F, or it may be a horizontal plane at any other arbitrary height.

[0047] (Information Processing Device 1) The information processing device 1 is a device for determining the positional relationship between the first transmitter 21 and the second transmitter 22 using a plurality of receivers 3. The configuration of the information processing device 1 will be described with reference to Figure 2. Figure 2 is a block diagram showing an example of the configuration of the information processing device 1. As an example, the information processing device 1 includes a control unit 10, a storage unit 11, a communication interface 12, and an input / output unit 13, as shown in Figure 2. Here, the information processing device 1 may be connected to external devices such as receivers 3 via a network N, as shown in Figure 2. Specific examples of the information processing device 1 include laptop computers, tablet computers, desktop computers, and wearable computers. Another specific example of the information processing device 1 is a smartphone.

[0048] (Control Unit 10) The control unit 10 controls all parts of the information processing device 1. As shown in Figure 2, the control unit 10 includes a position identification unit 101.

[0049] (Location specifying unit 101) The position identification unit 101 identifies the first position and the second position, which are the respective positions of the first transmitter 21 and the second transmitter 22.

[0050] The first position is the position where the first transmitter 21 is located. For example, the first position may be the position where the first transmitter 21 is fixed, as described above. The second position is the position where the second transmitter 22 is located. For example, the second position may be the position where the second transmitter 22 is fixed, as described above. For example, the first and second positions may be indicated by coordinates on a predetermined coordinate axis set in the vertical direction. Here, for example, the origin on the predetermined coordinate axis may be the intersection point with the reference plane described above. Also, for example, the predetermined coordinate axis may be set in the "axial direction" when the vibrating part V and the cable CA connected to the vibrating part V are suspended in a substantially vertical direction.

[0051] For example, the first interval d1 may be a predetermined distance from the tip of the vibrating part V to the first position when viewed along the axial direction. Also, for example, the second interval d2 may be a predetermined distance from the first position to the second position when viewed along the axial direction.

[0052] Furthermore, if the first communication between each of the multiple receivers 3 and the first transmitter 21 is interrupted, and the second communication between each of the multiple receivers 3 and the second transmitter 22 is established, the position determination unit 101 determines the second position according to the communication result of the second communication, and determines the first position according to the second position and the second interval d2.

[0053] The first communication is between each of the multiple receivers 3 and the first transmitter 21. The second communication is between each of the multiple receivers 3 and the second transmitter 22. For example, the first and second communications may be communications using radio waves transmitted by the first transmitter 21 and the second transmitter 22, respectively. Here, for example, the first and second communications may be communications using frequencies in UWB, as described above.

[0054] Here, for example, the position of each of the multiple receivers 3 may be set such that at least one of the multiple receivers 3 can establish a first communication with a first transmitter 21 located inside the concrete pouring area. Alternatively, for example, the position of each of the multiple receivers 3 may be set such that at least one of the multiple receivers 3 can establish a second communication with a second transmitter 22 located inside the concrete pouring area.

[0055] For example, as shown in Figure 1, if the first communication is interrupted because the first transmitter 21 is in concrete CO, and a second communication is established between each of the multiple receivers 3 and the second transmitter 22, the position identification unit 101 may identify the second position by using the radio waves emitted by the second transmitter 22 to calculate the distance between each of the multiple receivers 3 and the second transmitter 22. Then, for example, the position identification unit 101 may identify the first position as a position that has a second distance d2 from the second position toward the first transmitter 21 when viewed along the axial direction.

[0056] (Storage unit 11) The memory unit 11 stores various data referenced by the control unit 10, as well as various data generated by the control unit 10. Specific examples of data stored in the memory unit 11 include the first interval d1, the second interval d2, the first position, the second position, the communication results of the first communication, the communication results of the second communication, the position of the reference plane, and the positions of each of the multiple receivers 3 (the first height h1 and second height h2 described later).

[0057] (Communication interface 12) The communication interface 12 is an interface that connects the information processing device 1 to the network N. The communication interface 12 may be a wireless communication interface or a wired communication interface.

[0058] (Input / output section 13) The input / output unit 13 is configured to include at least one of the following input / output devices: a keyboard, mouse, display, printer, touch panel, etc. Alternatively, the input / output unit 13 may be configured to have input / output devices such as a keyboard, mouse, display, printer, touch panel, etc. connected to it. In this configuration, the input / output unit 13 receives various types of information from the connected input device to the information processing device 1. The input / output unit 13 also outputs various types of information to the connected output device under the control of the control unit 10. An interface such as USB (Universal Serial Bus) can be used as the input / output unit 13.

[0059] (Flow of Compaction Management Method M10) The flow of the compaction management method M10 executed by the compaction management system 0 will be explained with reference to Figure 3. Figure 3 is a flowchart showing the flow of the compaction management method M10. The compaction management method M10 is a concrete compaction management method that uses a rod-shaped vibrating section V for compacting the poured concrete, a first transmitter 21 fixed at a predetermined first interval d1 from the tip of the vibrating section V when viewed along the axial direction, a second transmitter 22 fixed at a predetermined second interval d2 from the first transmitter 21 when viewed along the axial direction, a plurality of receivers 3 arranged to surround the concrete pouring area and to communicate with each of the first transmitter 21 and the second transmitter 22, and a control unit 10. As shown in Figure 3, the compaction management method M10 includes a position identification step S11.

[0060] (Location identification step S11) The position determination step S11 is performed by the control unit 10 to determine the first position and the second position, which are the respective positions of the first transmitter 21 and the second transmitter 22. Furthermore, the position determination step S11 is performed when the first communication between each of the multiple receivers 3 and the first transmitter 21 is interrupted, and the second communication between each of the multiple receivers 3 and the second transmitter 22 is established, to determine the second position according to the communication result of the second communication, and to determine the first position according to the second position and the second interval d2.

[0061] [Embodiment 2] Other embodiments of the present invention are described below. For the sake of clarity, components having the same function as those described in the above embodiments will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0062] (Overview of the compaction management system 0 according to this embodiment) The compaction management system 0 according to this embodiment is a system for determining the depth to which a vibrator used in concrete compaction work is embedded in concrete, similar to the compaction management system 0 according to Embodiment 1. The main difference between the compaction management system 0 according to this embodiment and the compaction management system 0 according to Embodiment 1 is that there are at least multiple types of heights from the reference plane for the multiple receivers 3.

[0063] (Configuration of the compaction management system 0 according to this embodiment) The configuration of the compaction management system 0 according to this embodiment will be described with reference to Figure 4. Figure 4 is a cross-sectional view of concrete and formwork illustrating an example of the configuration of the compaction management system 0 according to this embodiment. As an example, the compaction management system 0 according to this embodiment includes a vibration unit V, a first transmitter 21, a second transmitter 22, a plurality of first receivers 31, a plurality of second receivers 32, and an information processing device 1, as shown in Figure 4. Here, the plurality of first receivers 31 and the plurality of second receivers 32 are all included in the plurality of receivers 3. The vibration unit V, the first transmitter 21, the second transmitter 22, and the information processing device 1 may be the same as those of the vibration unit V, the first transmitter 21, the second transmitter 22, and the information processing device 1 according to Embodiment 1, so their description is omitted here.

[0064] (Multiple first receivers 31 and multiple second receivers 32) For example, as described above, with a predetermined horizontal plane in the concrete casting area as the reference plane, the plurality of receivers 3 may include a plurality of first receivers 31 whose height from the reference plane is a predetermined first height h1, and a plurality of second receivers 32 whose height from the reference plane is a predetermined second height h2 that is different from the first height h1.

[0065] The multiple first receivers 31 and the multiple second receivers 32 are all receivers included in the multiple receivers 3. The height of the multiple first receivers 31 from the reference plane is a predetermined first height h1. The height of the multiple second receivers 32 from the reference plane is a predetermined second height h2 that is different from the first height h1. For example, the reference plane may be the horizontal plane at the lower end of the formwork F, as shown in Figure 4. Alternatively, for example, the second height h2 may be set so that at least one of the multiple second receivers 32 can establish a second communication with a second transmitter 22 located inside the pouring area.

[0066] For example, as described above, the casting area may be defined by a formwork F equipped with plate-like members surrounding the casting area. Here, for example, a plurality of first receivers 31 may be fixed at a predetermined position above the upper end of the formwork F. Also, for example, a plurality of second receivers 32 may be fixed at a predetermined position above the lower end and below the upper end of the formwork F.

[0067] (When multiple second receivers 32 are fixed outside the pouring area) In the following section, as an example, we will explain the case where multiple second receivers 32 are fixed outside the concrete pouring area, referring to Figure 4.

[0068] For example, the plate-shaped member according to this embodiment may be made of a dielectric material. Specific examples of plate-shaped members made of dielectric material include wooden plate-shaped members such as plywood or resin plate-shaped members.

[0069] Here, for example, as shown in Figure 4, the multiple second receivers 32 may be fixed to the outside of the concrete pouring area, surrounding the concrete pouring area. For example, the multiple second receivers 32 according to this embodiment may be fixed to pillars or scaffolding provided on the outside of the concrete pouring area.

[0070] Other configurations in the compaction management system 0 according to this embodiment may be the same as the configuration of the same name in the compaction management system 0 according to Embodiment 1, so their description is omitted here.

[0071] [Embodiment 3] Other embodiments of the present invention are described below. For the sake of clarity, components having the same function as those described in the above embodiments will be denoted by the same reference numerals, and their descriptions will not be repeated.

The main difference between the compaction management system 0 according to this embodiment and the compaction management system 0 according to Embodiment 2 is that a plurality of second receivers 32 are provided inside the pouring area.

[0073] (Configuration of the compaction management system 0 according to this embodiment) The configuration of the compaction management system 0 according to this embodiment will be described with reference to Figure 5. Figure 5 is a cross-sectional view of concrete and formwork illustrating an example of the configuration of the compaction management system 0 according to this embodiment. As an example, the compaction management system 0 according to this embodiment includes a vibration unit V, a first transmitter 21, a second transmitter 22, a plurality of first receivers 31, a plurality of second receivers 32, and an information processing device 1, as shown in Figure 5.

[0074] (When multiple second receivers 32 are provided inside the concrete pouring area) In the following section, as an example, a case in which multiple second receivers 32 are provided inside the concrete pouring area will be described with reference to Figure 5. The other configurations of the multiple second receivers 32 may be the same as those of the multiple second receivers 32 according to Embodiment 2, so their description will be omitted here.

[0075] For example, the plate-shaped member according to this embodiment may be made of metal. A specific example of a plate-shaped member made of metal is a steel plate-shaped member. Also, as described above, a metal structural member may be placed inside the casting area.

[0076] Here, for example, as shown in Figure 5, the multiple second receivers 32 are provided inside the concrete casting area, and the second height h2 may be configured to be variable in the vertical direction. For example, each of the multiple second receivers 32 according to this embodiment may be suspended inside the concrete casting area using a rod or rope. In this case, for example, the second height h2 may be configured to be variable in the vertical direction by raising or lowering the rod or rope from which each of the multiple second receivers 32 is suspended. In the example in Figure 5, only one second receiver 32 suspended using a rod or rope is described, and the other second receivers 32 are not described.

[0078] [Embodiment 4] Other embodiments of the present invention are described below. For the sake of clarity, components having the same function as those described in the above embodiments will be denoted by the same reference numerals, and their descriptions will not be repeated.

[0079] (Overview of the compaction management system 0A according to this embodiment) The compaction management system 0A according to this embodiment is a system for determining the depth to which a vibrator used in concrete compaction work is embedded in concrete, similar to the compaction management system 0 according to embodiments 1 to 3. The main difference between the compaction management system 0A according to this embodiment and the compaction management system 0 according to embodiment 1 is that, when a second layer of concrete is poured on top of a first layer of poured concrete, the system determines the depth to which the vibrator is inserted in the first layer.

[0080] (Configuration of Compaction Management System 0A) The configuration of the compaction management system 0A will be explained with reference to Figure 6. Figure 6 is a cross-sectional view of concrete and formwork illustrating an example of the configuration of the compaction management system 0A.

[0081] More specifically, Figure 6 illustrates a situation where a vibrating section V is inserted into the first layer of concrete CO1, when a second layer of concrete CO2 is poured on top of the first layer of concrete CO1. The first layer of concrete CO1 is the poured layer of concrete. The second layer of concrete CO2 is the layer of concrete poured on top of the first layer CO1 after compaction of the first layer CO1 is complete. For example, the point at which compaction of the poured concrete layer is complete may be when the concrete becomes approximately flat due to compaction. In other words, for example, the second layer CO2 may be the layer of concrete poured on top of the first layer CO1 after the first layer CO1 has become approximately flat due to compaction. The point at which compaction of the poured concrete layer is complete may be determined, for example, by the user.

[0082] As an example, the compaction management system 0A includes a vibration unit V, a first transmitter 21, a second transmitter 22, a plurality of receivers 3, and an information processing device 1A, as shown in Figure 6. The vibration unit V, the first transmitter 21, and the second transmitter 22 may be the same as those in Embodiment 1, so their description is omitted here.

[0083] (Information Processing Device 1A) The information processing device 1A, like the information processing device 1 described in Embodiment 1, is a device for determining the positional relationship between the first transmitter 21 and the second transmitter 22 using a plurality of receivers 3. The main difference between the information processing device 1A and the information processing device 1 is that, when the second layer CO2 is poured on top of the first layer CO1, the depth to which the vibrating part is inserted into the first layer CO1 is determined.

[0084] The configuration of the information processing device 1A will be described with reference to Figure 7. Figure 7 is a block diagram showing an example configuration of the information processing device 1A. As an example, the information processing device 1A includes a control unit 10A, a storage unit 11, a communication interface 12, and an input / output unit 13, as shown in Figure 7. Here, the information processing device 1A may be connected to each other via a network N with multiple external devices such as receivers 3, as shown in Figure 7. The communication interface 12 and the input / output unit 13 may be the same as the communication interface 12 and input / output unit 13 according to Embodiment 1, so their description will be omitted here.

[0085] (Control Unit 10A) The control unit 10A controls all parts of the information processing device 1A. As shown in Figure 7, the control unit 10A includes a position identification unit 101, a surface position identification unit 102, an insertion depth identification unit 103, and a thickness identification unit 104.

[0086] (Surface position identification unit 102) The surface position identification unit 102 identifies a first position based on the communication result of at least one of the first and second communications at the time when the first communication is restored after interruption, after the first vibration unit V and the first transmitter 21 have been continuously inserted into and removed from the poured concrete, and identifies the identified first position as the surface position of the concrete. The surface position is the position of the surface in the concrete layer. For example, after the vibration unit V and the first transmitter 21 have been continuously inserted into and removed from the poured concrete, the vibration unit V and the first transmitter 21 may be inserted into the concrete layer immediately before the completion of compaction in the concrete layer. Then, for example, the surface position identification unit 102 may identify a first position based on the communication result of at least one of the first and second communications at the time when the first transmitter 21 is exposed to the outside of the concrete and the first communication is restored after interruption, and identifies the identified first position as the surface position of the concrete.

[0087] (Identification of the first surface position) For example, the surface position identification unit 102 may identify a first surface position, which is the surface position of the first layer CO1 of the poured concrete after compaction is complete.

[0088] (Location identification unit 101 according to this embodiment) For example, the position identification unit 101 according to this embodiment may identify the first position when the vibrating unit V and the first transmitter 21 are inserted into the second layer CO2 of concrete that has been poured on top of the first layer CO1.

[0089] (Insertion depth specification unit 103) The insertion depth determination unit 103 determines the insertion depth de of the vibrating unit V in the first layer CO1 according to the first surface position, the first position, and the first interval d1. The insertion depth de is an indicator of how far the vibrating unit V has been inserted into the first layer CO1. For example, the insertion depth de may be indicated by the tip position of the vibrating unit V relative to the first surface position.

[0090] For example, the insertion depth determination unit 103 may determine the tip position of the vibrating unit V as a position having a first interval d1 from the first position determined by the position determination unit 101 according to this embodiment, when viewed along the axial direction described above. Then, for example, the insertion depth determination unit 103 may determine the distance of the tip position of the vibrating unit V to the first surface position, when viewed along the axial direction, as the insertion depth de.

[0091] Furthermore, for example, the insertion depth determination unit 103 may determine whether the insertion depth de exceeds a predetermined depth threshold. A specific example of a predetermined depth threshold is 10 cm.

[0092] (Identification of the second surface location) Furthermore, for example, the surface position identification unit 102 may identify the second surface position, which is the surface position after compaction of the second layer of CO2.

[0093] (Thickness-specific section 104) The thickness determination unit 104 determines the thickness th of the concrete layer in the second CO2 layer according to the first surface position and the second surface position. For example, the thickness determination unit 104 may determine the distance between the first surface position and the second surface position when viewed along the axial direction as the thickness th of the concrete layer in the second CO2 layer.

[0094] Furthermore, for example, the thickness determination unit 104 may determine whether the thickness th of the concrete layer exceeds a predetermined thickness threshold. A specific example of a predetermined thickness threshold is 50 cm.

[0095] (Storage unit 11 according to this embodiment) The storage unit 11 according to this embodiment stores various data referenced by the control unit 10A, and various data generated by the control unit 10A. Specific examples of data stored by the storage unit 11 according to this embodiment include the first interval d1, the second interval d2, the first position, the second position, the communication result of the first communication, the communication result of the second communication, the position of the reference surface, the positions of each of the multiple receivers 3 (first height h1 and second height h2), the first surface position, the insertion depth de, a predetermined depth threshold, the second surface position, the thickness th of the concrete layer, a predetermined thickness threshold, and so on.

[0096] Other configurations in the information processing device 1A may be the same as those of the same name in the information processing device 1, so their explanation is omitted here.

[0097] (Example of installation with multiple receivers 3) For example, each of the multiple receivers 3 may have a communication area. Also, for example, the concrete pouring area may be included in a superimposed area where at least two communication areas overlap.

[0098] The communication area is the area in each of the multiple receivers 3 that includes the location of the first transmitter 21 where first communication can be established, and the location of the second transmitter 22 where second communication can be established. For example, the communication area of ​​each of the multiple receivers 3 may be within the range centered on the normal direction to the receiving surface of the radio waves in each of the multiple receivers 3. Here, the communication area may be within the range defined by the elevation angle direction and the azimuth angle direction centered on the normal direction. The "elevation angle direction" is the vertical angle range centered on the normal direction. The "azimuth angle direction" is the horizontal angle range centered on the normal direction.

[0099] Figure 8 is a cross-sectional view of the formwork F illustrating an example of installation with multiple receivers 3. In Figure 8, as an example, multiple receivers 3 fixed to the upper end of the formwork F are shown. In other words, these multiple receivers 3 may be, for example, a first receiver 31. Also in Figure 8, as an example, the pouring area defined by the formwork F is shown with diagonal lines. Also in Figure 8, as an example, the dimensions of each part are indicated in millimeters. Note that in Figure 8, the description of components other than the formwork F and the multiple receivers 3 fixed to the upper end of the formwork F is omitted.

[0100] In the example shown in Figure 8, the communication range for each of the multiple receivers 3 is from -40 degrees to +40 degrees in the elevation direction. Also, in the example shown in Figure 8, the formwork F is a cube shape with sides of 4000 mm. Here, in the example shown in Figure 8, in order to ensure that the pouring area is included in the overlapping area, each of the multiple receivers 3 is installed 1000 mm above the formwork F and is installed so that its normal direction is tilted 55 degrees downward from the horizontal. Note that all of the values ​​mentioned above with reference to Figure 8 are examples only.

[0101] Other configurations in the compaction management system 0A according to this embodiment may be the same as the configurations of the same name in the compaction management system 0 according to embodiments 1 to 3, so their description is omitted here.

This program can also be described as a program that causes a computer to execute each step (which can also be rephrased as "each process," "each procedure," "each step," etc.) included in the compaction management method described in the above embodiment.

For example, an integrated circuit in which logic circuits functioning as each of the above control blocks are formed is also included in the scope of the present invention. In addition, it is also possible to realize the functions of each of the above control blocks by, for example, a quantum computer.

[0106] Furthermore, each process described in the above embodiments may be performed by AI (Artificial Intelligence). In this case, the AI ​​may operate on the control device described above, or it may operate on other devices (for example, an edge computer or a cloud server).

[0107] The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Examples]

[0108] One embodiment of the present invention is described below.

[0109] In this embodiment, the installation conditions for multiple receivers 3 were verified.

[0110] The concrete pouring area was a cube with sides of 4m. A total of four receivers 3 were installed above each of the four sides of the cube-shaped concrete pouring area. Here, the receivers 3 were installed 1m above the midpoint of the upper side of each square-shaped side. The communication range of the receivers 3 was within the range of -40 to +40 degrees in the elevation direction and within the range of -80 to +80 degrees in the azimuth direction. In addition, the receivers 3 were installed so that the normal direction of the receivers 3 was tilted 55 degrees downward from the horizontal.

[0111] The concrete pouring area was divided into virtual subdivisions, each 50 cm high. Then, the "transmitters" corresponding to the first transmitter 21 and the second transmitter 22 were tested to see if they could be detected by multiple receivers 3 in each subdivision. This test was conducted both with and without reinforcing bars between the "transmitters" and the multiple receivers 3.

[0112] The verification results showed that multiple receivers 3 detected the location and time of the "transmitters" installed in all divided areas, regardless of the presence or absence of reinforcing bars. Therefore, it was confirmed that multiple receivers 3 could establish communication with the "transmitters" under the installation conditions described above. [Examples]

[0113] Other embodiments of the present invention are described below.

[0114] In this embodiment, we verified the case in which, in the "case where reinforcing bars are present" as in Example 1, the multiple receivers 3 installed above the pouring area were made into multiple first receivers 31, and further multiple second receivers 32 were installed on the side of the pouring area.

[0115] Multiple second receivers 32 were installed, a total of four, around each of the four sides of the cube-shaped concrete pouring area. Here, the multiple second receivers 32 were installed within 50 cm horizontally outward from the intersection of the diagonals on each square-shaped side. In addition, plywood panels simulating plate-like members were installed on each square-shaped side.

[0116] The verification results showed that multiple first receivers 31 and multiple second receivers 32 detected the location and time of the "transmitters" installed in all divided areas. Therefore, it was confirmed that multiple first receivers 31 and multiple second receivers 32 can establish communication with the "transmitters" under the installation conditions described above.
