[0003] [Patent Document 1] JP 2019-023402 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the method of Patent Document 1 uses a plurality of distance meters, including a distance meter separate from the tool, and therefore has a problem in that it is cumbersome to configure the tool at the site where ready-mixed concrete is poured.

[0005] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a pouring management system that can properly pour ready-mixed concrete. [Means for solving the problem]

[0008] A desirable embodiment of the implantation management system includes a second transmitter attached to the insertion tool and emitting radio waves, the receiver receives the radio waves emitted from the second transmitter, and the control device obtains the position of the second transmitter based on the reception status of the radio waves from the second transmitter by the receiver.

[0009] In a preferred embodiment of the driving management system, the control device acquires local coordinates of the second transmitter based on the arrival speed and incident angle of the radio wave emitted from the second transmitter at the receiver.

[0010] In a preferred embodiment of the driving management system, the control device obtains the insertion position of the insertion tool based on the reception state immediately before the receiver stops receiving the radio waves transmitted from the first transmitter.

[0011] In a preferred embodiment of the implantation management system, a repeater is provided which is attached to the insertion tool and repeats the radio waves transmitted from the first transmitter to the receiver.

[0012] In a preferred embodiment of the driving management system, a display device is provided for displaying information visually indicating the insertion state of the insertion tool.

[0013] In a preferred embodiment of the pouring management system, the pouring location where the ready mixed concrete is poured is divided into a plurality of sections when viewed in a plane, and the display device has a display screen which visually shows a plurality of display sections corresponding to the plurality of sections, and displays the insertion state of the insertion tool in each of the plurality of sections in the corresponding display sections.

[0018] The following describes in detail an embodiment of the driving management system according to the present disclosure with reference to the drawings. Note that the present disclosure is not limited to the description of the following embodiment. Furthermore, the components in the following embodiment include those that are replaceable and easy for a person skilled in the art, or those that are substantially identical. Furthermore, the components in the embodiments described below may be omitted, replaced, or modified in various ways without departing from the gist of the present disclosure. In the following embodiment, the components necessary to illustrate an embodiment of the driving management system according to the present disclosure are described, and other components are omitted.

[0019] (First embodiment) [System configuration] Fig. 1 is a diagram showing a schematic configuration of a driving management system 1 according to the first embodiment. Fig. 2 is a block diagram showing a functional configuration of the driving management system 1 according to the first embodiment. Fig. 3 is a diagram showing an example of a display screen 78 of the display device 70 shown in Fig. 1.

[0020] The pouring management system 1 of the first embodiment is a system that allows a manager A, a worker W, etc. to grasp the insertion state of an insertion tool 20 to be inserted into ready mixed concrete B when performing compaction processing on ready mixed concrete B poured into a pouring location 10 at a pouring site of the ready mixed concrete B. As shown in Figs. 1 and 2, the pouring management system 1 of the first embodiment comprises an insertion tool 20, a first transmitter 30, a second transmitter 40, a receiver 50, a wireless hub 60, a display device 70, and a control device 80.

[0021] In the first embodiment, the pouring site 10 is a predetermined area where a reinforced concrete structure having reinforcing bars 12 is constructed. The reinforcing bars 12 are arranged in a lattice pattern inside a formwork set up around the pouring site 10. Manager A and worker W perform various tasks while standing on the reinforcing bars 12 set up like beams. Ready-mixed concrete B is supplied to the inside of the formwork in multiple layers (e.g., lower layer B1 and upper layer B2 in Figs. 4 and 5) from a hose connected to a supply source such as an agitator truck.

[0022] A pouring site 10 where ready-mixed concrete B is poured is divided into a plurality of sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, and 10l in a plan view. In the first embodiment, the sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, and 10l are square-shaped with sides of 50 cm in a plan view.

[0023] The insertion tool 20 is a tool whose tip is inserted into the ready-mixed concrete B when pouring the ready-mixed concrete B. In the first embodiment, the insertion tool 20 is a tool that performs a compaction process on the ready-mixed concrete B after being poured into the ready-mixed concrete B at the pouring location 10. In the first embodiment, the insertion tool 20 includes an insertion portion 22 and a cable portion 24.

[0024] The insertion part 22 is a portion of the insertion tool 20 that is inserted into the ready-mixed concrete B. In the first embodiment, the insertion part 22 includes a vibrating body, i.e., a vibrator, that applies vibration to the ready-mixed concrete B to promote compaction. The insertion part 22 is, for example, rod-shaped with a diameter of about 50 mm and a longitudinal length of about 40 cm.

[0025] The insertion part 22 is inserted downward from the surface of the ready-mixed concrete B along the longitudinal direction. The insertion part 22 of the insertion tool 20 is inserted into only one predetermined location in each of the sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, and 10l of the pouring location 10, and is not moved in the horizontal direction. The insertion part 22 applies vibration to the inside of the ready-mixed concrete B. The insertion part 22 applies vibration to the ready-mixed concrete B for, for example, 15 seconds. After being vibrated and compacted, the ready-mixed concrete B is cured for a predetermined time to harden.

[0026] The cable portion 24 is waterproof and flexible. The cable portion 24 is connected to an end of the insertion portion 22 that is located at the top when the insertion portion 22 is inserted into the ready-mixed concrete B. The cable portion 24 is connected to, for example, a power source and a switch to supply power for vibrating the vibrator of the insertion portion 22. For example, the worker W holds the cable portion 24 and inserts the insertion portion 22 into the ready-mixed concrete B by lowering the insertion portion 22 downward while keeping the insertion portion 22 hanging vertically downward.

[0027] The first transmitter 30 transmits radio waves for the control device 80 described later to determine the insertion state of the insertion tool 20. The radio waves transmitted by the first transmitter 30 are radio waves that are significantly attenuated in the ready-mix concrete B. The radio waves include, for example, short-range wireless communication standards such as Bluetooth (registered trademark), Wi-Fi (registered trademark), or ZiBbee (registered trademark) in the 2.4 GHz band, or radio waves of the ultra-wideband (UWB; Ultra Wide Band) communication standard in the bands of 3.4 to 4.8 GHz and 7.25 to 10.25 GHz. The radio waves transmitted by the first transmitter 30 are preferably radio waves having a frequency of 433 MHz or more that is significantly attenuated in water. The first transmitter 30 includes, for example, an active tag that communicates by RFID (Radio Frequency Identifier). The active tag is a tag that has a built-in battery and emits radio waves using its own power during communication.

[0028] The first transmitter 30 is attached at a position at a predetermined distance from the tip of the insertion tool 20. In the first embodiment, the first transmitter 30 is attached to the cable part 24. The position at which the first transmitter 30 is attached is a position that exists inside from the surface of the fresh concrete B when the insertion tool 20 is inserted into the fresh concrete B at a predetermined insertion depth. The first transmitter 30 is attached at a position where the transmitted radio wave is sufficiently attenuated before propagating to the outside of the fresh concrete B when the insertion tool 20 is inserted into the fresh concrete B at a predetermined insertion depth. "Sufficiently attenuated" means that the radio wave transmitted from the first transmitter 30 cannot be detected by the receiver 50 described later.

[0029] The second transmitter 40 transmits radio waves for the control device 80 (described later) to acquire the insertion position of the insertion instrument 20 in a planar view. The radio waves include, for example, radio waves of short-range wireless communication standards such as Bluetooth, Wi-Fi, or ZiBbee in the 2.4 GHz band, or ultra-wideband (UWB) communication standards in the 3.4 to 4.8 GHz or 7.25 to 10.25 GHz band. The second transmitter 40 includes, for example, an active tag that communicates by RFID.

[0030] The second transmitter 40 is attached to a position farther from the tip of the insertion tool 20 than the first transmitter 30. In the first embodiment, the second transmitter 40 is attached to the cable part 24. The position at which the second transmitter 40 is attached is a position that is present on the outer side than the surface of the ready-mixed concrete B when the insertion tool 20 is inserted into the ready-mixed concrete B to a predetermined insertion depth.

[0031] The receiver 50 receives radio waves. The receiver 50 extracts, from the received radio waves, radio wave signals of the radio waves transmitted from the first transmitter 30 and the radio waves transmitted from the second transmitter 40. The receiver 50 transmits the extracted radio wave signals to the control device 80 via the communication network to which the wireless hub 60 belongs. The receiver 50 includes multiple receivers 52, 54, 56, and 58. The multiple receivers 52, 54, 56, and 58 are connected to the wireless hub 60 via wireless communication.

[0032] The wireless hub 60 is an access point of a wireless LAN (Local Area Network) that belongs to a communication network established at the driving site including the driving location 10. The wireless hub 60 may be, for example, a wireless LAN router. The wireless hub 60 connects the receiver 50, the display device 70, and the control device 80 to one another via a wireless network. Note that, in the embodiment, the communication network of the driving management system 1 is established so that each device is wirelessly connected via the wireless hub 60, but in the present disclosure, some connections may be made by wire.

[0033] The display device 70 displays various images for driving management. The display device 70 displays various information based on control signals including video signals and the like output from the control device 80. The display device 70 displays information visually indicating the insertion state of the insertion tool 20 into the driving location 10. The display device 70 is, for example, a display including a liquid crystal display (LCD) or an organic electro-luminescence (EL) display. The display device 70 may be a touch panel type display that functions as an operation unit that can input various operations.

[0034] The display device 70 includes, for example, a large monitor, an electronic board, a tablet terminal, a smartphone, a smart watch, a wearable monitor, etc. In the first embodiment, the display device 70 includes multiple types of display devices 72, 74, 76. In the first embodiment, the display device 72 is an electronic board installed in a position close to the driving location 10. In the first embodiment, the display device 74 is a tablet terminal operated by the manager A. In the first embodiment, the display device 76 is a smart watch worn by the worker W.

[0035] When the display device 70 is caused to display information showing the insertion status of the insertion tool 20 into the driving site 10, as shown in FIG. 3, the display screen 78 of each display device 70 is divided into a plurality of display sections 78a, 78b, 78c, 78d, 78e, 78f, 78g, 78h, 78i, 78j, 78k, and 78l corresponding to the plurality of sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, and 10l of the driving site 10.

[0036] In the example shown in Fig. 3, the display sections 78a, 78b, 78c, 78d, and 78e of the display screen 78 are displayed in gray, and the display sections 78f, 78g, 78h, 78i, 78j, 78k, and 78l are displayed in white. The display sections 78a, 78b, 78c, 78d, and 78e displayed in gray indicate that the compaction process by the insertion tool 20 has been performed in the sections 10a, 10b, 10c, 10d, and 10e of the corresponding driving location 10. The display sections 78f, 78g, 78h, 78i, 78j, 78k, and 78l displayed in white indicate that the compaction process by the insertion tool 20 has not been performed in the sections 10f, 10g, 10h, 10i, 10j, 10k, and 10l of the corresponding driving location 10.

[0037] The method of displaying the insertion state of the insertion tool 20 into the driving location 10 on the display device 70 is not limited to the first embodiment. For example, in the section 10e where the insertion tool 20 is being inserted into the ready-mixed concrete B for compaction processing, if the insertion tool 20 is not inserted to a predetermined insertion depth, the display section 78e may be displayed in red. The method of determining the insertion state of the insertion tool 20 will be described later.

[0038] The control device 80 controls the processing by the driving management system 1. The control device 80 includes a storage device in which various control programs and data used for various control processes are stored, an arithmetic processing device that executes predetermined control programs, and an input / output interface device as a means of communication with various devices of the driving management system 1. The control device 80 acquires the radio signal of the first transmitter 30 and the radio signal of the second transmitter 40 from the receiver 50 via the wireless hub 60. The control device 80 outputs control signals including video signals for displaying various images for driving management to the display device 70 via the wireless hub 60.

[0039] [How to determine the insertion status] FIG. 4 is a diagram for explaining the state of the insertion tool 20 when not inserted. FIG. 5 is a diagram for explaining the state of the insertion tool 20 when inserted. The example shown in FIG. 4 and FIG. 5 shows a compaction process in which a fresh concrete layer (n+1)th layer (hereinafter referred to as upper layer B2) is poured in the height direction on a fresh concrete layer (hereinafter referred to as lower layer B1) that has been poured previously (integer)th layer. When pouring fresh concrete B in multiple layers, each fresh concrete layer is set to a thickness of 50 cm or less. In the example shown in FIG. 4 and FIG. 5, the thickness h1 of the lower layer B1 and the upper layer B2 is, for example, 50 cm.

[0040] 4, when the insertion tool 20 is not inserted into the ready-mix concrete B, the first transmitter 30 is present outside the surface of the ready-mix concrete B. At this time, the radio waves transmitted from the first transmitter 30 are not impeded from propagation by the ready-mix concrete B, so that the receiver 50 can receive the radio waves transmitted from the first transmitter 30.

[0041] 5, in a state where the insertion tool 20 is inserted into the ready-mix concrete B at an insertion depth H, the first transmitter 30 is present inside the surface of the ready-mix concrete B. At this time, the radio waves transmitted from the first transmitter 30 are blocked from propagation by the ready-mix concrete B, and therefore the receiver 50 cannot receive the radio waves transmitted from the first transmitter 30.

[0042] The insertion depth H is the sum of the thickness h1 of the upper layer B2 and the depth h2 to which the insertion tool 20 is inserted into the lower layer B1. The depth h2 to which the insertion tool 20 is inserted into the lower layer B1 is the depth from the surface of the lower layer B1 to the tip of the insertion tool 20. For example, during construction, the position of the surface of the lower layer B1 is a position below the surface of the upper layer B2 being driven by the designed thickness of the upper layer B2. The depth h2 is 10 cm or more. The insertion depth H is, for example, 60 cm. When driving the upper layer B2 into the lower layer B1 in the middle of hardening, the tip of the insertion part 22 of the insertion tool 20 is inserted into the lower layer B1 and the upper layer B2 and the lower layer B1 are compacted together to suppress cold joints and integrate the upper layer B2 and the lower layer B1.

[0043] The control device 80 (see FIG. 2) judges the insertion state of the insertion tool 20 based on the reception state of the radio wave from the first transmitter 30 by the receiver 50. More specifically, the control device 80 judges whether the first transmitter 30 is inserted into the ready-mix concrete B or not, that is, whether the insertion tool 20 is inserted to a predetermined insertion depth into the ready-mix concrete B or not, based on whether the receiver 50 has received the radio wave transmitted from the first transmitter 30.

[0044] When the receiver 50 receives the radio waves transmitted from the first transmitter 30, the control device 80 determines that the insertion tool 20 is not inserted to a predetermined insertion depth into the ready-mix concrete B. When the receiver 50 does not receive the radio waves transmitted from the first transmitter 30, the control device 80 determines that the insertion tool 20 is inserted to a predetermined insertion depth into the ready-mix concrete B.

[0045] [How to get the insertion position] The control device 80 acquires the position of the second transmitter 40 based on the reception status of the radio wave from the second transmitter 40 by the receiver 50. The control device 80 acquires the insertion position of the insertion instrument 20 in a planar view based on the acquired position information of the second transmitter 40. The control device 80 acquires the local coordinates of the second transmitter 40 based on, for example, the radio wave arrival time and the incidence angle from the second transmitter 40 to each of the receivers 52, 54, 56, 58. The control device 80 stores the local coordinates acquired when the insertion instrument 20 is inserted into each of the sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, 10l (see FIG. 1). The control device 80 judges whether the insertion instrument 20 is properly inserted, for example, at 50 cm intervals in a planar view, based on each acquired local coordinate.

[0046] As described above, the pouring management system 1 of the first embodiment comprises an insertion tool 20 whose tip is inserted into the fresh concrete B when pouring the fresh concrete B, a first transmitter 30 that is attached to the insertion tool 20 so that the tip of the insertion tool 20 is located inside the surface of the fresh concrete B when inserted into the fresh concrete B at a predetermined insertion depth H and that emits radio waves, a receiver 50 that receives the radio waves emitted from the first transmitter 30, and a control device 80 that determines the insertion state of the insertion tool 20 based on the reception status of the radio waves from the first transmitter 30 by the receiver 50.

[0047] The appropriate insertion depth H of the insertion tool 20 is determined depending on the treatment of the ready-mixed concrete B. That is, in the pouring control system 1 of the first embodiment, when the insertion tool 20 is inserted at the appropriate insertion depth H during treatment, the first transmitter 30 is present inside the ready-mixed concrete B, and therefore the radio waves transmitted from the first transmitter 30 are significantly attenuated by the ready-mixed concrete B.

[0048] Therefore, depending on the reception status of the radio wave from the first transmitter 30 by the receiver 50, it can be determined whether the first transmitter 30 is present inside the ready-mixed concrete B, and therefore the insertion status of the insertion tool 20 to which the first transmitter 30 is attached can be determined. In this way, by determining the insertion status of the insertion tool 20 into the ready-mixed concrete B, the ready-mixed concrete B can be appropriately poured. In addition, by making a determination based on the reception status from the first transmitter 30 by the receiver 50, it is possible to easily determine the insertion status of the insertion tool 20, and therefore the pouring work of the ready-mixed concrete B can be made more efficient.

[0049] Furthermore, in the driving management system 1, when the receiver 50 receives radio waves transmitted from the first transmitter 30, the control device 80 determines that the insertion tool 20 is not inserted to the predetermined insertion depth H, and when the receiver 50 does not receive radio waves transmitted from the first transmitter 30, the control device 80 determines that the insertion tool 20 is inserted to the predetermined insertion depth H. As a result, depending on whether the receiver 50 receives radio waves from the first transmitter 30, it can be determined whether the first transmitter 30 is present inside the ready-mix concrete B, and therefore it can be determined whether the insertion tool 20 to which the first transmitter 30 is attached is inserted to the predetermined insertion depth H.

[0050] The pouring control system 1 also includes a second transmitter 40 that is attached to the insertion tool 20 and transmits radio waves, and in the pouring control system 1, a receiver 50 receives the radio waves transmitted from the second transmitter 40, and a control device 80 acquires the position of the second transmitter 40 based on the reception status of the radio waves from the second transmitter 40 by the receiver 50. This makes it possible to know the position where the insertion tool 20 is inserted, and therefore allows the ready-mix concrete B to be processed at an appropriate position in the pouring site 10.

[0051] Furthermore, in the pouring management system 1, the control device 80 acquires the local coordinates of the second transmitter 40 based on the arrival speed and incident angle of the radio waves emitted from the second transmitter 40 at the receiver 50. This makes it possible to ascertain the local coordinates of the position where the insertion tool 20 is inserted, and therefore allows processing of the ready-mix concrete B at an appropriate position in the pouring site 10.

[0052] The pouring control system 1 also includes a display device 70 that displays information visually indicating the insertion state of the insertion tool 20. This allows the manager A and the worker W to easily grasp the insertion state of the insertion tool 20, allowing the ready-mixed concrete B to be poured appropriately and the pouring work of the ready-mixed concrete B to be made more efficient.

[0053] In addition, in the pouring management system 1, the pouring site 10 where the ready-mixed concrete B is poured is divided into a plurality of sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, and 10l in a plan view, and the display device 70 has a display screen 78 that displays a plurality of display sections 78a, 78b corresponding to the plurality of sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, and 10l. , 78c, 78d, 78e, 78f, 78g, 78h, 78i, 78j, 78k, and 78l, and display information visually showing the insertion state of the insertion tool 20 in each of the multiple sections 10a, 10b, 10c, 10d, 10e, 10f, 10g, 10h, 10i, 10j, 10k, and 10l is displayed in the multiple display sections 78a, 78b, 78c, 78d, 78e, 78f, 78g, 78h, 78i, 78j, 78k, and 78l corresponding to each section. This allows the manager A and the worker W to easily grasp the insertion state of the insertion tool 20, so that the ready-mixed concrete B can be appropriately poured and the pouring work of the ready-mixed concrete B can be made more efficient.

[0054] In addition, in the pouring management system 1, the insertion tool 20 includes an insertion part 22 including a vibrator that, when inserted into the ready-mixed concrete B, vibrates the ready-mixed concrete B to promote compaction, and when the ready-mixed concrete B is poured in layers and an upper layer B2 is poured into a lower layer B1 that has been poured in advance, the first transmitter 30 is attached to the insertion tool 20 so that, when the tip of the insertion part 22 is inserted into the lower layer B1 at a predetermined depth h2, the first transmitter 30 is located inside the surface of the ready-mixed concrete B. As a result, when the ready-mixed concrete B is poured in layers, the insertion part 22 can be inserted to a suitable insertion depth H and the lower layer B1 and the upper layer B2 can be compacted together, thereby suppressing cold joints and integrating the upper layer B2 and the lower layer B1.

[0055] (First Modification of the First Embodiment) 6 is a block diagram showing the functional configuration of a driving management system 2 according to a first modified example of the first embodiment. In the driving management system 2 according to the first modified example of the first embodiment, the same components as those in the driving management system 1 according to the first embodiment are given the same reference numerals and explanations are omitted as appropriate, and different components will be described. The driving management system 2 according to the first modified example of the first embodiment differs from the driving management system 1 according to the first embodiment in that it includes a first transmitter 32 and a repeater 90 instead of the first transmitter 30 and the second transmitter 40.

[0056] The first transmitter 32, like the first transmitter 30 of the first embodiment, transmits radio waves for the control device 80 to determine the insertion state of the insertion tool 20. The attachment position of the first transmitter 32 is similar to that of the first transmitter 30 of the first embodiment. That is, the attachment position of the first transmitter 32 is a position that is present inside from the surface of the ready-mixed concrete B when the insertion tool 20 is inserted into the ready-mixed concrete B to a predetermined insertion depth.

[0057] The repeater 90 relays the radio waves transmitted from the first transmitter 32 to the receiver 50. The repeater 90 is attached in the same position as the second transmitter 40 in the first embodiment. That is, the position at which the repeater 90 is attached is a position farther from the tip of the insertion tool 20 than the first transmitter 30, and is a position that is present on the outer side than the surface of the ready-mixed concrete B when the insertion tool 20 is inserted into the ready-mixed concrete B to a predetermined insertion depth.

[0058] The method in which the control device 80 of the first modified example of the first embodiment determines the insertion state of the insertion tool 20 is the same as that of the first embodiment. That is, when the first transmitter 32 is present outside the surface of the ready-mixed concrete B, the radio waves transmitted from the first transmitter 32 propagate to the receiver 50 via the repeater 90. When the receiver 50 receives the radio waves transmitted from the first transmitter 32, the control device 80 determines that the insertion tool 20 is not inserted into the ready-mixed concrete B to a predetermined insertion depth.

[0059] When the first transmitter 32 is present inside the surface of the ready-mix concrete B, the radio waves transmitted from the first transmitter 32 are blocked by the ready-mix concrete B and are not transmitted to the receiver 50 via the repeater 90. When the receiver 50 does not receive the radio waves transmitted from the first transmitter 32, the control device 80 determines that the insertion tool 20 has been inserted into the ready-mix concrete B to a predetermined insertion depth.

[0060] The control device 80 acquires the position of the repeater 90 based on the reception status of the radio wave from the first transmitter 32 via the repeater 90 by the receiver 50. The control device 80 acquires the insertion position of the insertion tool 20 in a planar view based on the acquired position information of the repeater 90. The control device 80 acquires the local coordinates of the repeater 90 based on, for example, the radio wave arrival time from the first transmitter 32 to each of the receivers 52, 54, 56, 58 and the incident angle of the radio wave from the repeater 90.

[0061] As described above, the pouring management system 2 of the first modified example of the first embodiment includes the repeater 90 that is attached to the insertion tool 20 and relays the radio waves transmitted from the first transmitter 32 to the receiver 50. As a result, even when pouring ready-mixed concrete B at a pouring location 10 with many obstacles or at a pouring location 10 where the receiver 50 cannot be located near the insertion tool 20, the radio waves transmitted from the first transmitter 32 outside the ready-mixed concrete B can be propagated to the receiver 50.

[0062] (Second Modification of the First Embodiment) 7 is a block diagram showing the functional configuration of a driving management system 3 according to a second modified example of the first embodiment. In the driving management system 3 according to the second modified example of the first embodiment, the same components as those in the driving management system 1 according to the first embodiment are given the same reference numerals and their explanations are omitted as appropriate, and only different components will be explained. The driving management system 3 according to the second modified example of the first embodiment differs from the driving management system 1 according to the first embodiment in that it has a first transmitter 34 instead of the first transmitter 30 and the second transmitter 40.

[0063] The first transmitter 34 emits radio waves for the control device 80 to determine the insertion state of the insertion tool 20 and to acquire the insertion position in a plan view of the insertion tool 20. The attachment position of the first transmitter 34 is similar to that of the first transmitter 30 in the first embodiment. That is, the attachment position of the first transmitter 34 is a position that is present inside from the surface of the ready-mixed concrete B when the insertion tool 20 is inserted into the ready-mixed concrete B to a predetermined insertion depth.

[0064] The method in which the control device 80 of the second modified example of the first embodiment determines the insertion state of the insertion tool 20 is the same as that of the first embodiment. That is, when the first transmitter 32 is present on the outer side of the surface of the ready-mixed concrete B, the radio waves transmitted from the first transmitter 34 are not blocked by the ready-mixed concrete B and propagate to the receiver 50. When the receiver 50 receives the radio waves transmitted from the first transmitter 34, the control device 80 determines that the insertion tool 20 is not inserted into the ready-mixed concrete B to a predetermined insertion depth.

[0065] When the first transmitter 34 is present inside the surface of the ready-mix concrete B, the radio waves transmitted from the first transmitter 32 are blocked by the ready-mix concrete B and are not transmitted to the receiver 50. When the receiver 50 does not receive the radio waves transmitted from the first transmitter 34, the control device 80 determines that the insertion tool 20 is inserted into the ready-mix concrete B to a predetermined insertion depth.

[0066] The control device 80 periodically acquires the reception status of radio waves from the first transmitter 34 by the receiver 50. The control device 80 acquires the insertion position of the insertion device 20 based on the reception status immediately before the receiver 50 stops receiving radio waves transmitted from the first transmitter 34. The control device 80 acquires the insertion position of the insertion device 20 in a planar view based on the acquired position information of the first transmitter 34. The control device 80 acquires the local coordinates of the first transmitter 34 based on, for example, the arrival time and incident angle of radio waves from the first transmitter 34 to each of the receivers 52, 54, 56, 58.

[0067] As described above, in the pouring management system 3 of the second modified example of the first embodiment, the control device 80 acquires the insertion position of the insertion tool 20 based on the reception status immediately before the receiver 50 stops receiving radio waves transmitted from the first transmitter 34. This makes it possible to grasp the insertion state and insertion position of the insertion tool 20 based on the reception status of radio waves transmitted from one transmitter (the first transmitter 34). Therefore, with a simple configuration, it is possible to appropriately pour the ready-mixed concrete B at an appropriate position in the pouring location 10 and to make the pouring work of the ready-mixed concrete B more efficient.

[0068] Second embodiment 8 is a diagram showing a schematic configuration of the driving management system 4 according to the second embodiment. In the driving management system 4 of the second embodiment, the same components as those in the driving management system 3 of the second modified example of the first embodiment are given the same reference numerals and the description is omitted as appropriate, and only different components will be described.

[0069] The pouring control system 4 of the second embodiment is a system for allowing a manager, worker, etc. to grasp the insertion state of an insertion tool 120 to be inserted into the ready-mixed concrete B when performing a pouring process on the ready-mixed concrete B poured into the pouring site 110 during pouring of the ready-mixed concrete B. As shown in FIG. 8, the pouring control system 4 of the second embodiment comprises an insertion tool 120 and a first transmitter 34. Similarly to the second modified example of the first embodiment, the pouring control system 4 of the second embodiment also comprises a receiver 50, a wireless hub 60, a display device 70, and a control device 80, but these are not shown in FIG. 8.

[0070] In the second embodiment, the driving site 110 includes a vertical hole that is excavated for driving foundation piles or the like into the ground G. A cylindrical reinforcing bar cage 112, which is a reinforcing bar for the pile, is set in the hole of the driving site 110. Furthermore, an insertion tool 120 is set in the inside of the reinforcing bar cage 112.

[0071] In the second embodiment, the insertion tool 120 is a tubular tool that supplies, from its lower end (tip), the ready-mixed concrete B received from a hopper 126 attached to its upper end. In the second embodiment, the insertion tool 120 is a tremie pipe. The tip of the insertion tool 120 is placed at the bottom of the hole in the pouring location 110, and supplies the ready-mixed concrete B to the bottom of the hole. It is preferable that the insertion tool 120 is successively raised while the ready-mixed concrete B is being supplied to the hole, so that the insertion portion 122 at the tip does not rise above the layer of ready-mixed concrete B poured in advance, and so that the insertion depth H is maintained approximately constant.

[0072] The first transmitter 34 in the second embodiment is attached at a position a predetermined distance from the tip of the insertion part 122 of the insertion tool 120. The position at which the first transmitter 34 is attached is a position that is present inside from the surface of the fresh concrete B when the insertion part 122 of the insertion tool 20 is inserted into the fresh concrete B at a predetermined insertion depth H.

[0073] That is, when pouring concrete over previously poured ready-mixed concrete B, the insertion part 122 is inserted into the previously poured ready-mixed concrete B. At this time, if the insertion part 122 is not inserted to a predetermined insertion depth H, the first transmitter 34 is present on the outer side than the surface of the ready-mixed concrete B. At this time, since the radio waves transmitted from the first transmitter 34 are not blocked from propagating to the ready-mixed concrete B, the receiver 50 (see Figs. 1, 7, etc.) can receive the radio waves transmitted from the first transmitter 34. When the receiver 50 receives the radio waves transmitted from the first transmitter 34, the control device 80 (see Figs. 2, 7, etc.) determines that the insertion tool 120 is not inserted into the ready-mixed concrete B to the predetermined insertion depth H.

[0074] When the insertion portion 122 is inserted to a predetermined insertion depth H, the first transmitter 34 is present inside the surface of the ready-mix concrete B. At this time, the radio waves transmitted from the first transmitter 34 are blocked from propagation by the ready-mix concrete B, and the receiver 50 (see Figs. 1, 7, etc.) cannot receive the radio waves transmitted from the first transmitter 34. When the receiver 50 does not receive the radio waves transmitted from the first transmitter 34, the control device 80 (see Figs. 2, 7, etc.) determines that the insertion tool 120 is inserted into the ready-mix concrete B to a predetermined insertion depth H.

[0075] As described above, in the pouring management system 4 of the second embodiment, the insertion tool 120 includes a tremie pipe that supplies ready-mixed concrete B from its tip, and when the tip (insertion part 122) of the tremie pipe is inserted into the previously poured ready-mixed concrete B to pour it over, the first transmitter 34 is attached to the tremie pipe so as to be located inside the surface of the ready-mixed concrete B when the tip of the tremie pipe is inserted into the previously poured ready-mixed concrete B at a predetermined insertion depth H. This makes it possible to determine the insertion state of the tremie pipe to which the first transmitter 34 is attached by checking the reception status of the radio wave transmitted from the first transmitter 34 when the tremie pipe is successively pulled up while supplying ready-mixed concrete B. Therefore, the insertion depth H can be maintained substantially constant so that the insertion part 122 at the tip of the tremie pipe does not rise up from the layer of the previously poured ready-mixed concrete B, and the ready-mixed concrete B can be poured appropriately.

[0076] Each configuration described in each embodiment may be combined with other configurations in each embodiment without departing from the spirit of the invention. Furthermore, each of these configurations may be combined with configurations in other embodiments different from each embodiment without departing from the spirit of the invention. Furthermore, various modifications may be made without departing from the spirit of the invention.

[0077] For example, in the first embodiment, the local coordinates of the second transmitter 40 are obtained based on the radio wave arrival time and incident angle at the receiver 50 of the radio wave transmitted from the second transmitter 40, but the global coordinates may be obtained by the GNSS (Global Navigation Satellite System).
