  The surface leveling device of Patent Document 1 smoothes the concrete surface smoothly by applying a load to the concrete surface by the leveling plate. In addition to the surface smoothing work performed by the surface leveling apparatus of Patent Document 1, so-called compacting work for improving strength and durability is performed on the concrete after placing. For this compacting operation, a device such as the surface leveling device of Patent Document 1 can be used. However, in a compacting operation using a device such as the surface leveling device of Patent Document 1, there is a risk that quality such as the smooth state, strength, and durability of the concrete surface may vary.

  Accordingly, an object of the present invention is to provide a concrete compaction management system and a concrete compaction management method capable of reducing variations in concrete quality.

  One aspect of the present invention is a surface compaction device having a compaction plate that can slide in contact with a concrete surface, and a vibration generating unit that vibrates the compaction plate in a direction intersecting the concrete surface. A concrete compaction management system for managing concrete compaction work performed by an operator moving on a concrete surface after placement, and a speed at which speed data indicating a travel speed of a compaction plate is acquired. A data acquisition unit, a passage number counting unit that acquires the number of times the surface compaction device has passed through a predetermined area using at least one of position data and speed data indicating the position of the compaction plate, and speed And a display unit that displays at least one of the data and the frequency data in a manner that is visible to the operator.

  As a result of intensive studies by the inventors, in concrete compaction work using a surface compaction device, it is found that the variation in concrete quality is related to the moving speed of the compaction plate and the number of times the compaction plate has passed. I found it. In the concrete compaction management system according to one aspect of the present invention, speed data and frequency data are acquired. The compaction management system displays at least one of these data in a state that is visible to the operator who operates the surface compaction device. As a result, the operator can check the state of the data related to the variation in the concrete quality, so that the operation state of the surface compaction device is set so that the displayed data becomes a value indicating a good working state. Can be operated while adjusting. Therefore, according to the concrete compaction management system according to one embodiment of the present invention, it is possible to reduce the variation in concrete quality.

  The concrete compaction management system further includes a vibration data acquisition unit that is attached to the surface compaction device and acquires vibration data indicating a vibration state of the compaction plate. The display unit includes at least one of speed data and frequency data. The vibration data may be displayed in a manner that is visible to the operator. In concrete compaction work, the variation in concrete quality is further related to the vibration state of the compaction plate. According to this configuration, the data indicating the vibration state is acquired by the vibration data acquisition unit, and the operator can check the vibration data by the display unit. Therefore, according to the concrete compaction management system according to one aspect of the present invention, it is possible to further reduce variations in concrete quality.

Furthermore, you may provide. According to this configuration, the vibration data comparison unit determines whether the vibration data is good or bad. Since the operator can know the result by the vibration state notifying unit, it is not necessary to judge the quality of the vibration data. Therefore, since the variation in the quality judgment of the vibration data by the operator is eliminated, the variation in the concrete quality can be further reduced.

Output from the frequency data comparison unit and the frequency data comparison unit that outputs at least one of information indicating that it is out of the range and information indicating that the frequency data is within the allowable range indicated in the required frequency data It may further include a number notification unit for reporting information. According to this configuration, the number data comparison unit determines whether the number data is good or bad. Since the operator can know the result by the number-of-times state notifying unit, it is not necessary to remember the number of times of passing through the predetermined area. Therefore, the surface compaction device can be reliably passed through the predetermined area a predetermined number of times, so that the variation in concrete quality can be further reduced.

  The concrete compaction management system may further include a data recording unit that records vibration data, position data, and speed data. According to this configuration, each data during the compacting operation is stored. Accordingly, it is possible to confirm after the compacting operation whether the compacting operation has been performed so as to satisfy a preset condition. Therefore, the reliability of the quality of concrete can be improved.

According to this configuration, vibration data that directly indicates the vibration state of the compaction plate can be obtained.

  The speed data acquisition unit uses a marker attached to the surface compaction device, a camera that acquires a marker image including the marker, a position calculation unit that calculates position data using the marker image, and the position data. You may have the speed calculation part which calculates speed data. According to this configuration, the position and speed of the surface compaction device are acquired by image processing. Therefore, speed data in which the influence of the vibration of the compaction plate is suppressed can be obtained.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

<First Embodiment>
A concrete compaction management system (hereinafter also simply referred to as “management system”) according to the first embodiment will be described. As shown in FIG. 1, the management system 1 gives a management function to the surface compaction device 100. The surface compaction device 100 is operated by an operator M. Each element constituting the management system 1 may be attached to the surface compaction apparatus 100 from the beginning, or may be detachably attached to the surface compaction apparatus 100. The management system 1 has a function of displaying data acquired using various sensors. The operator M operates the surface compaction apparatus 100 so as to obtain a good compacted state while confirming the displayed data.

  First, the surface compaction device 100 will be described. As shown in FIG. 2, the surface compaction apparatus 100 performs a surface compaction operation while moving on the concrete surface C after placing. Hereinafter, XYZ orthogonal coordinates with the Z axis as the vertical axis and the XY plane as the horizontal plane are defined, and X, Y, and Z are used in the following description. Moreover, in this embodiment, the concrete surface C used as the object of surface compaction shall be a horizontal surface. In FIG. 2, in order to facilitate understanding of the description, the shape and size of each part of the surface compaction device 100 may be exaggerated and the dimensional ratio on the drawing does not necessarily match the actual one. do not do.

  The surface compaction device 100 includes a compaction plate 101, a vibration generating unit 102 for vibrating the compaction plate 101, and a handle 107 for dragging and moving the compaction plate 101 on the concrete surface C. .

  The compaction plate 101 has a flat plate shape having a longitudinal direction in the X direction. The length of the compaction plate 101 in the X direction is, for example, about 2.5 m. On the bottom surface of the compaction plate 101, a compaction surface is formed that can slide in contact with the concrete surface C. The compaction plate 101 includes a frame for mounting the vibration generating unit 102 and the like on the upper surface of the compaction plate 101.

  The vibration generator 102 vibrates the compaction plate 101 in a direction (Z direction) intersecting the concrete surface. The vibration generating unit 102 includes a rotation driving unit 103, two vibrating bodies (eccentric weights) 104 that vibrate upon receiving power from the rotation driving unit 103, and a shaft that transmits the power from the rotation driving unit 103 to the vibrating body 104. 106. The rotation drive unit 103 is mounted at the center of the compaction plate 101 in the X direction. As the rotation drive unit 103, for example, an internal combustion engine or a motor can be employed. The two vibrating bodies 104 are arranged at positions symmetrical to each other in the X direction with the rotation drive unit 103 interposed therebetween, and are fixed to the upper surface of the compaction plate 101, respectively. As the vibrating body 104, for example, a vibrating device including a weight that rotates following rotation of the shaft 106 can be employed. Two locations on the compaction plate 101 to which the vibrating body 104 is attached are vibration transmission locations V at which vibration from the vibration generating unit 102 is transmitted to the compaction plate 101. The vibration generating unit 102 can control the rotation speed of the rotation driving unit 103.

  The handle 107 has a U shape in plan view and is coupled to the compaction plate 101 via two connecting portions 108. The connecting portion 108 has a hinge structure with the X direction as an axis, and the handle 107 can rotate around the X axis with respect to the compaction plate 101. Further, the two connecting portions 108 are provided at positions symmetrical to each other in the X direction when viewed from the center of the compaction plate 101. The operator M can drag and move the compaction plate 101 on the concrete surface C by pulling the handle 107.

  In addition, the brake mechanism (not shown) which intentionally prohibits the rotation of the handle 107 with respect to the compaction plate 101 by a predetermined operation by the operator M, and a lever which adjusts the rotation speed of the vibration generating unit 102 An operating means may be provided. According to the brake mechanism, the operator M prohibits the rotation of the handle 107, thereby facilitating the operation of intentionally lifting the compaction plate 101 and overcoming the uneven surface of the concrete surface C. Further, according to the lever for adjusting the rotation speed, the compaction condition can be adjusted.

  Next, the management system 1 shown in FIG. 1 will be described. The management system 1 has a function of acquiring and displaying three pieces of data related to the concrete quality in the compacting operation. According to the knowledge of the inventors, the vibration state of the compaction plate 101, the moving speed of the compaction plate 101, and the number of times the compaction plate 101 has passed through a predetermined area are related to the concrete quality. Therefore, the management system 1 displays the sensors 2 for acquiring the vibration state, the moving speed, and the number of passages, the data processing device 3 for processing the data output from the sensors 2, and the processed data. And a display (display unit) 4.

  The sensors 2 include an acceleration sensor (acceleration measurement unit) 6 that acquires vibration data indicating the vibration state of the compaction plate 101. The acceleration sensor 6 acquires vibration data indicated as an acceleration history and outputs the vibration data to the data processing device 3. The vibration data is transmitted to the data processing device 3 by wired communication or wireless communication. The acceleration sensor 6 is a so-called acceleration pick or the like, and is attached in the vicinity of both ends of the compaction plate 101 (see FIG. 2).

  The sensors 2 have a marker 7 and a camera 8. The markers 7 are respectively attached in the vicinity of both ends of the compaction plate 101 (see FIG. 2). The camera 8 acquires a marker image including the marker 7 attached to the surface compaction device 100 and outputs the marker image to the data processing device 3. The camera 8 is disposed at a different location from the surface compaction device 100. The camera 8 is arranged at a position where an image including the entire work area where the compacting work is performed can be acquired. The marker image is transmitted to the data processing device 3 by wired communication or wireless communication. The marker 7, the camera 8, and the position calculation unit 9 described later constitute a position acquisition unit.

  The data processing device 3 includes a position calculation unit 9, a speed calculation unit 11, a passage number counting unit 12, and a data recording unit 13 as functional components. Each functional element of the data processing device 3 reads predetermined software on the CPU or the main storage unit, operates the communication control unit, the input device, the output device, and the like under the control of the CPU, and operates the main storage unit or the auxiliary unit. This is realized by reading and writing data in the storage unit. Data and databases necessary for processing are stored in the main storage unit or the auxiliary storage unit.

  The position calculation unit 9 calculates position data indicating the position of the surface compaction device 100 using the marker image input from the camera 8. For calculating the position of the surface compaction apparatus 100, a known image processing method such as a stereo matching method can be used. The position of the surface compaction device 100 is shown as a two-dimensional coordinate based on the concrete surface C. Therefore, the position data includes the time when the marker image is captured and two-dimensional coordinates as information. The position data is output to the speed calculation unit 11, the passage number counting unit 12, and the display 4.

  The speed calculation unit 11 calculates speed data indicating the moving speed of the surface compaction apparatus 100 using the position data. Here, the speed data includes the moving direction of the surface compaction apparatus 100 and the speed. For example, the speed calculation unit 11 calculates speed data as a moving speed per unit time using a difference between position data at a predetermined time and position data at another time. Further, the speed calculation unit 11 may calculate speed data by differentiating the time history of the position data with respect to time. The speed data is output to the display 4.

  The passage number counting unit 12 acquires the number of times data indicating the number of times the surface compaction device 100 has passed through the predetermined area by using at least one of the position data and the velocity data. It is assumed that the passing number counting unit 12 of the present embodiment acquires the number data using position data. For example, the passage number counting unit 12 generates data obtained by dividing an area to be compacted into a plurality of rectangular small areas. At least one side of the small region is equal to or smaller than the lateral width of the compaction plate 101. Then, the number of times the position of the surface compaction device 100 indicated by the position data overlaps these small areas is counted. This number is acquired as the number data. The count data is output to the display 4.

  The vibration data input from the acceleration sensor 6 to the data processing device 3 is output to the display 4 after performing desired processing. Vibration data, position data, speed data, and number of times data are recorded in the data recording unit 13, respectively.

  The display 4 displays vibration data, position data, speed data, and frequency data in a manner that the worker M can visually recognize. As an aspect which can be visually recognized, the numerical value of each data may be displayed in real time, and the time-dependent change of each data may be displayed as a graph, for example.

  Next, a concrete compaction management method using the management system 1 will be described. As shown in FIG. 3, first, the worker M determines the rotation speed of the rotation drive unit 103 of the surface compaction device 100 (step S1). The number of revolutions is determined by the temperature, humidity, concrete components, and the like during the compacting operation, and is appropriately adjusted during the compacting operation. Next, the surface compaction device 100 is disposed at an initial position on the concrete surface C (step S2). Note that step S2 may be performed prior to step S1.

  Next, the operator M grips the handle 107 and drags and moves the surface compaction device 100 while controlling the rotation driving unit 103 so that the number of rotations determined in step S1 is achieved. At this time, the management system 1 acquires vibration data (step S3), speed data (step S4), and frequency data (step S5), and displays each data (step S6). Is done. Then, the worker M confirms these data displayed on the display 4, and determines whether or not the vibration data and the speed data are within an allowable range (step S7). When the operator M determines that it is not acceptable (step S7: NO), the operation state of the surface compaction device 100 is adjusted (step S8). Specifically, when the vibration data is not within an allowable range, the rotation speed of the rotation drive unit 103 is adjusted. If the speed data is not within an allowable range, the speed at which the operator M pulls the surface compaction device 100 is adjusted. On the other hand, when the worker M determines that it is acceptable (step S7: YES), the process proceeds to the next step (step S9).

  In step S9, it is confirmed whether or not all the areas have been compacted in the work area where the compaction work is to be performed. For example, the number of times the surface compaction device 100 should pass is set for each of the small areas in the preset work area. The worker M compares the number of times to pass with the number of times actually passed, and determines whether or not the compacting operation has been completed. When the actual number of times of passage is less than the number of times of passage (step S9: NO), steps S1 to S7 are repeated again. On the other hand, when the actual number of times of passage becomes equal to the number of times of passage (step S9: YES), the compaction operation is terminated.

  Here, the concrete quality by the compaction work using the surface compaction apparatus 100 will be described. In the compacting operation, the compaction plate 101 moves on the concrete surface C while vibrating, so that air and excess moisture in the concrete surface layer escape. If the air and excess moisture are removed, the concrete surface layer becomes dense, and the strength and durability of the concrete increase. However, to improve concrete strength and durability, it is necessary to ensure sufficient compaction work at an appropriate time and to transmit sufficient vibration to the concrete surface layer. Therefore, when these conditions are not satisfied, it is difficult to sufficiently improve the concrete strength and durability.

  For example, FIG. 4 is a graph comparing the compaction effects when the worker M having different characteristics performs the compaction work. Graph G1 shows the result when finishing with a normal plasterer without performing surface compaction. Graph G2 shows the results when a construction worker skilled in compaction work performs the work as he thinks best. Graph G3 shows the results when a construction worker skilled in compaction work moves the surface compaction device 100 faster than deemed to be the best. Graph G4 shows the result when a construction worker who is not proficient in the compaction work performs the compaction work. According to the graphs G1 to G4, it was found that the operator M has a large difference in the compaction effect. That is, it was found that factors such as the sensation and ability of the worker M have an influence on the concrete quality obtained by the compacting operation. Further, it was found that the highest compaction effect can be obtained when the worker M who is proficient in the compaction work performs the compaction work. Further, even if the worker M is proficient in compaction work, the compaction effect can be significantly reduced under conditions (eg, the surface compaction device 100 is moved quickly) that deviates from the conditions that the worker considers good. I understood.

  As a result of intensive studies by the inventors on the difference in compaction effect shown in FIG. 4, in the concrete compaction work using the surface compaction device 100, the variation in concrete quality caused by the operator M is compacted. It has been found that the vibration state of the plate 101, the moving speed of the compaction plate 101, and the number of times the compaction plate 101 has passed are related. In the management system 1, vibration data, speed data, and frequency data are acquired. Then, the management system 1 displays these data in a state that is visible to the worker M who operates the surface compaction device 100. Then, the worker M can check the state of data related to the variation in concrete quality. In addition, since the parameters related to the concrete quality can be displayed as specific numerical values or graphs, the work state can be objectively grasped regardless of the sense and ability of the worker M. Therefore, it can be operated while adjusting the operating state of the surface compaction device 100 so that the displayed data becomes a value indicating a good working state. Therefore, according to the management system 1 and the management method, variation in concrete quality can be reduced and uniform concrete quality can be obtained.

  The management system 1 includes a data recording unit 13. Each data during the compacting operation is stored in the data recording unit 13. Accordingly, it is possible to confirm after the compacting operation whether the compacting operation has been performed so as to satisfy a preset condition. Therefore, according to the management system 1, the traceability regarding the compacting work can be provided and the reliability of the quality of the concrete can be enhanced.

  The management system 1 includes a marker 7 attached to the surface compaction device 100, a camera 8 that acquires a marker image including the marker 7, a position calculation unit 9 that calculates position data using the marker image, and position data. Is used to calculate speed data. According to this configuration, the position and speed of the surface compaction device 100 are acquired by image processing. Accordingly, speed data in which the influence of vibration of the compaction plate 101 is suppressed can be obtained.

Second Embodiment
A concrete compaction management system according to the second embodiment will be described. As shown in FIG. 5, the management system 1A is different from the management system 1 of the first embodiment in the sensors that constitute the sensors 2A. Since different measurement data is output for different sensors, the configuration for acquiring vibration data, speed data, and frequency data in the data processing device 3A is also different. Moreover, in the management system 1 of 1st Embodiment, the operator M performed the quality determination of vibration data, speed data, and frequency data. In the second embodiment, the quality judgment of these data is also different in that the management system 1A performs the judgment. Furthermore, the management system 1A is different from the management system 1 in that it has three lamps 22, 23, 24 instead of the display 4.

  The sensors 2 </ b> A have a rotation speed sensor (rotation speed measurement unit) 16. The rotation speed sensor 16 is attached to the rotation drive unit 103 of the vibration generation unit 102, acquires rotation speed data of the rotation drive unit 103, and outputs the rotation speed data to the data processing device 3A.

  The sensor group 2 </ b> A includes an inertial measurement sensor (inertia measurement unit) 14. The inertial measurement sensor 14 includes an angular velocity meter such as an accelerometer or a gyroscope configured in three axes or two axes. The inertial measurement sensor 14 is attached to the surface compaction apparatus 100 at a location that is not easily affected by the vibration generating unit 102. The inertial measurement sensor 14 may be attached to the surface compaction device 100 via a vibration isolator (not shown). The inertial measurement sensor 14 acquires, for example, an acceleration related to two axes (X axis, Y axis) parallel to the concrete surface C and an angular velocity around an axis (Z axis) orthogonal to the concrete surface C, The data is output to the data processing device 3A.

  The data processing device 3A includes a vibration calculating unit 17, a speed calculating unit 11A, a position calculating unit 9A, and a passing number counting unit 12A as functional components. Further, the data processing device 3 </ b> A includes a vibration data comparison unit 18, a speed data comparison unit 19, and a frequency data comparison unit 21.

  The vibration calculation unit 17 calculates vibration data using the rotation speed data output from the rotation speed sensor. The vibration data is calculated based on the rotation speed, the weight of the eccentric weight attached to the rotation driving unit 103, and the amount of eccentricity. The vibration data is output to the vibration data comparison unit 18.

  The vibration data comparison unit 18 determines whether the vibration data is acceptable. The vibration data comparison unit 18 determines whether or not the vibration data is within an allowable range indicated by the allowable vibration data by comparing the vibration data with the allowable vibration data input in advance. The result of this determination may be output as information indicating that the vibration data is within the allowable range, or may be output as information indicating that the vibration data is outside the allowable range. Information indicating the determination result is output to the lamp 22.

  The lamp (vibration state notifying unit) 22 notifies the worker M of the result of the quality determination of the vibration data in a manner visible to the worker M. For example, the lamp 22 has red and blue light sources. When information indicating that the vibration data is within the allowable range is input, only the blue lamp is turned on. On the other hand, when information indicating that the vibration data is outside the allowable range is input, only the red lamp is turned on. The lamp 22 may not only notify that the vibration data is within the allowable range or outside the allowable range, but may also notify that the vibration data is larger or smaller than the allowable range.

  The speed calculation unit 11A integrates the acceleration output from the inertial measurement sensor 14 to calculate speed data. The speed data is output to the speed data comparison unit 19 and the position calculation unit 9A.

  The speed data comparison unit 19 determines whether the speed data is acceptable. The speed data comparison unit 19 determines whether or not the speed data is within an allowable range indicated by the allowable speed data by comparing the speed data with the allowable speed data input in advance. The result of this determination may be output as information indicating that the speed data is within the allowable range, or may be output as information indicating that the speed data is outside the allowable range. Information indicating the determination result is output to the lamp 23.

  The lamp (speed state notifying unit) 23 notifies the worker M of the result of the pass / fail judgment on the speed data in a manner visible to the worker M. For example, the lamp 23 has red and blue light sources. When information indicating that the speed data is within the allowable range is input, only the blue lamp is turned on. On the other hand, when information indicating that the speed data is outside the allowable range is input, only the red lamp is turned on. Note that the lamp 23 may not only notify that the speed data is within the allowable range or outside the allowable range, but may also notify that the speed data is larger or smaller than the allowable range.

  The position calculation unit 9A calculates position data of the surface compaction device 100 using the speed data calculated by the speed calculation unit 11A. In the calculation of the position data, the angular velocity output from the inertial measurement sensor 14 may be used together. The position data is output to the passage number counting unit 12A.

  The passage number counting unit 12A is the same as the passage number counting unit 12 of the first embodiment, and a detailed description thereof is omitted.

  The number data comparison unit 21 determines whether the number data is good or bad. The number-of-times data comparison unit 21 compares the number-of-times data with the necessary number of times data indicating the number of times the surface compaction apparatus 100 should pass before the compaction operation is completed. The number-of-times data comparison unit 21 includes information indicating that the number of times data is less than the required number of times indicated in the required number of times data, and information indicating that the number of times data has reached the required number of times indicated in the required number of times data. Output at least one. Information indicating the determination result is output to the lamp 24.

  The lamp (number notifying unit) 24 notifies the worker M of the result of determining whether the number data is good or bad. For example, the lamp 24 has red and blue light sources. When information indicating that the number data is less than the required number indicated in the required number data is input, only the red lamp is turned on. On the other hand, when information indicating that the number of times data has reached the required number of times indicated in the required number of times data is input, only the blue lamp is turned on. Therefore, the operator M can know that the compacting operation is not completed when the lighting color of the lamp 24 is red, and the compacting operation is completed when the lighting color of the lamp 24 is blue. I can know that.

  Next, a concrete compaction management method using the management system 1A will be described. As shown in FIG. 6, first, the worker M performs the steps S1 and S2 in the same manner as the management method of the first embodiment. Next, the operator M grips the handle 107 and drags and moves the surface compaction device 100 while controlling the rotation driving unit 103 so that the number of rotations determined in step S1 is achieved. At this time, the management system 1A performs vibration data acquisition (step S3), speed data acquisition (step S4), and number of times data acquisition (step S5), and the quality of each data is determined (step). S11). As described above, in the management method according to the second embodiment, the management system 1A performs the pass / fail judgment that was performed by the worker M in the management method according to the first embodiment. And the result of a quality judgment is alert | reported by lamp | ramp 22,23,24 (process S12).

  The worker M confirms the state of the lamps 22 and 23 (step S13). In step S13, when it is informed that the lamps 22 and 23 are outside the allowable range (S13: NO), the operation state of the surface compaction device 100 is adjusted (step S8). On the other hand, when the lamps 22 and 23 are informed that they are within the allowable range (S13: YES), the process proceeds to the next step S14. In step S14, the state of the lamp 24 is confirmed. When the lamp 24 notifies that the compacting operation has not been completed (step S14: NO), the steps S3 to S13 are repeated again. On the other hand, when the lamp 24 notifies that the compacting operation has been completed (step S14: YES), the compacting operation is terminated.

Further, the speed data comparison unit 19 determines whether the speed data is good or not, and the operator M can know the result by the lamp 23. Further, whether or not the frequency data is good is determined by the frequency data comparison unit 21, and the operator M can know the result by the lamp 24. Therefore, the worker M does not need to judge whether each data is acceptable. Therefore, since the variation in the quality determination of each data by the worker M is eliminated, the variation in the concrete quality can be further reduced.
