Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the technologies described in Patent Documents 1 and 2 have the following problems when considering the management of daily work progress, and did not sufficiently reduce the burden on workers. In Patent Document 1, a vibratory roller moving around an embankment construction site transmits positional information. However, since the vibratory roller moves around the embankment construction site in addition to performing compaction, it is conceivable that positional information unnecessary for managing the completed work may also be transmitted. Therefore, organizing the data when managing the completed work becomes troublesome. Furthermore, compaction work using a vibratory roller includes both vibration-assisted and vibration-free operations, but it is not possible to accurately determine the number of vibration-assisted and vibration-free compaction operations. Furthermore, Patent Document 2 requires a special process for taking photographs and measurements using aircraft or unmanned aerial vehicles, and in order to improve the accuracy of the measurements, other work must be temporarily suspended. As a result, the work process is prolonged by the amount of time that work is interrupted for the sake of measurement. From this perspective, the present invention provides a construction progress management system, a construction progress management method, and a location acquisition system that can reduce the burden required to manage construction progress compared to conventional methods. [Means for solving the problem]

[0006] The construction progress management system according to the present invention is a construction progress management system for managing the construction progress in earthworks. This construction progress management system comprises a vibration detection means for detecting vibrations of a vibratory roller, a position detection means for detecting the position of the vibratory roller, and a construction progress management device that creates construction progress information based on the vibration information detected by the vibration detection means and the position information detected by the position detection means. The construction progress management device creates the construction progress information using position information acquired during the time period in which the vibration force generated during compaction work is detected by the vibration detection means. In the construction progress management system according to the present invention, the vibration state of a vibratory roller can be determined and its position information can be acquired. Here, in general, earthwork involves transporting soil with dump trucks, spreading the soil with bulldozers, and finally compacting it with a vibratory roller to finish the job. Therefore, if the position information of the vibratory roller is known, it can be said that the construction progress has been measured. In addition, although the vibratory roller moves around the construction site in addition to compaction, it moves in a vibrating state only when compaction is being performed. Therefore, by associating the presence or absence of vibration of the vibratory roller with its position information, position information that is unnecessary for construction progress management can be eliminated. In other words, it is possible to acquire position information only for compaction when vibration is present during compaction work. As a result, it becomes possible to automate daily construction progress management without requiring any special work procedures.

[0007] The vibration detection means is a transmitter attached to the vibratory roller. For example, the transmitter is equipped with an acceleration sensor and emits radio waves when it detects the vibration force generated during compaction work. The construction management device creates the construction information using location information acquired during the time when the transmitter is emitting radio waves. This method makes it easy to obtain positional information of the vibrating roller while it is in a vibrating state.

[0008] The device includes a receiver that receives radio waves emitted by the transmitter. For example, the receiver is attached to a vibratory roller to which the transmitter is mounted. The construction management device creates the construction information using location information acquired during the time period when the receiver receives radio waves with a radio wave intensity of a predetermined value or higher. Since the distance between the transmitter and receiver attached to a single vibratory roller remains constant, the signal strength of the radio waves received by the receiver is always above a predetermined value. Therefore, even when multiple vibratory rollers are working at a work site, it is difficult to confuse the radio waves emitted by transmitters attached to other vibratory rollers with the radio waves emitted by the transmitter attached to one's own vibratory roller. Consequently, it is possible to accurately manage the work progress even when multiple vibratory rollers are working at a work site.

[0009] The completed work information may be a representation of the completed area as a surface shape, obtained by adding the width information of the vibratory roller to the travel trajectory of the vibratory roller. In this case, the completed work management device displays image data that reflects the completed area in the design information of the earthwork on its display unit. This method makes it possible to grasp the progress of the earthworks at a glance.

[0010] The construction progress management method according to the present invention is a construction progress management method for managing the construction progress in earthworks. This construction progress management method comprises a detection step for detecting the vibration and position of a vibratory roller, and a construction progress management step for creating construction progress information based on the vibration information and position information detected in the detection step. In the construction progress management step, the construction progress information is created using position information acquired during the time period in which the vibration force generated during compaction work is detected. In the construction progress management method according to the present invention, the vibration state of the vibratory roller can be determined and its position information can be acquired. Knowing the position information of the vibratory roller is equivalent to measuring the construction progress. Furthermore, although the vibratory roller moves around the construction site in addition to compaction, it only moves while vibrating when compaction is being performed. Therefore, by associating the presence or absence of vibration of the vibratory roller with its position information, position information unnecessary for construction progress management can be eliminated. In other words, only position information for vibration during compaction work can be acquired. As a result, daily construction progress management can be performed automatically without requiring any special work procedures.

[0011] The position acquisition system according to the present invention is a position acquisition system that acquires position information of a vibratory roller. This position acquisition system comprises a vibration detection means for detecting vibrations of the vibratory roller, a position detection means for detecting the position of the vibratory roller, and a control device. The control device outputs position information acquired during the time period in which the vibration force generated during compaction work is detected by the vibration detection means. In the position acquisition system according to the present invention, position information can be acquired by determining whether the vibrating roller is vibrating. Knowing the position information of the vibrating roller is equivalent to measuring the completed work. Furthermore, although the vibrating roller moves around the construction site in addition to compaction, it moves in a vibrating state only when compaction is being performed. Therefore, by associating the presence or absence of vibration of the vibrating roller with its position information, position information unnecessary for managing the completed work can be eliminated. In other words, it is possible to acquire position information only for compaction work in which vibration occurs. As a result, by using the position information obtained from the position acquisition system, it becomes possible to automatically manage the completed work on a daily basis without requiring any special work processes.

[Modes for carrying out the invention]

[0014] Hereinafter, embodiments for implementing the present invention will be described in detail with reference to the drawings as appropriate. Each drawing only schematically shows the present invention to such an extent that it can be fully understood. Therefore, the present invention is not limited only to the illustrated examples. In each drawing, common components and similar components are denoted by the same reference numerals, and redundant descriptions thereof are omitted.

[0015] ≪Configuration of the formed shape management system according to the embodiment≫ Referring to FIGS. 1 to 3, the configuration of the formed shape management system 100 according to the embodiment will be described. FIG. 1 is a conceptual diagram of the formed shape management system 100. FIG. 2 is a system configuration diagram of the formed shape management system 100. FIG. 3 is a schematic side view of the vibrating roller 1. The formed shape management system 100 is a system for managing the daily formed shapes in geotechnical work. In this embodiment, the embankment work is assumed as the geotechnical work for explanation.

[0016] As shown in FIG. 1, the formed shape management system 100 includes one or more vibrating rollers 1, a cloud system 2, and a formed shape management device 3. The vibrating roller 1 and the formed shape management device 3 can transmit and receive data to and from the cloud system 2. The vibrating roller 1 compresses the ground while traveling on the construction site. The vibrating roller 1 has a vibration function and can compress the ground with the roller vibrating. The cloud system 2 is a system that acquires and holds information related to the construction of geotechnical work. In the cloud system 2, for example, the position information of the vibrating roller 1 is stored.

[0017] The formed shape management device 3 is a device for managing the daily formed shapes in geotechnical work. The formed shape management device 3 creates formed shape information related to the formed shape, for example, using the position information of the vibrating roller 1 stored in the cloud system 2. The formed shape information is, for example, a representation of the constructed area where the compaction work has been completed in a planar shape. The configuration of the construction progress management system 100 is not limited to that shown herein. For example, the construction progress management device 3 may have some or all of the functions of the cloud system 2 (that is, the construction progress management system 100 may consist of one or more vibratory rollers 1 and the construction progress management device 3).

[0018] As shown in Figure 2, the vibratory roller 1 includes a vibration detection means 4 for detecting vibrations of the vibratory roller 1 and a position detection means 5 for detecting the position of the vibratory roller 1. The vibration information detected by the vibration detection means 4 and the position information detected by the position detection means 5 are transmitted to the cloud system 2 and used for managing the completed work by the completed work management device 3. In this embodiment, the vibration detection means 4 is assumed to be an acceleration-type beacon (referred to as "acceleration beacon 31"), and the position detection means 5 is assumed to be a positioning signal receiving device 32. The acceleration beacon 31 is equipped with an acceleration sensor and is a transmitter that emits radio waves when an acceleration above a predetermined threshold is detected. The signal receiving device 32 is, for example, a radio wave receiving device used in GPS (Global Positioning System). The vibratory roller 1 may also be capable of automatic driving, in which case the vibratory roller 1 will travel around the construction site without an operator riding on it.

[0019] As shown in Figure 3, the vibratory roller 1 comprises a vehicle body 10 and a driving mechanism 20 located at the bottom of the vehicle body 10. The vehicle body 10 is the main body of the vibratory roller 1. The vehicle body 10 comprises a driver's seat 11 and a driving means (e.g., an engine or motor) not shown. The driving mechanism 20 comprises an articulating mechanism 21, rollers 22 as front wheels, and tires 23 as rear wheels.

[0020] The articulated mechanism 21 is a mechanism for rotating the vibratory roller 1 and is installed at the bottom of the vehicle body 10. The articulated mechanism 21 includes a front wheel holder 21a that rotatably holds the roller 22, a rear wheel holder 21b that rotatably holds the tire 23, and a center pin 21c that connects the front wheel holder 21a and the rear wheel holder 21b. A steering cylinder (not shown) is interposed between the front wheel holder 21a and the rear wheel holder 21b. When a control command to correct the direction of travel is received from a control unit (not shown), the steering cylinder extends and retracts according to the steering angle. When the steering cylinder extends and retracts, the front wheel holder 21a and the rear wheel holder 21b bend around the center pin 21c, and the direction of the roller 22 and the tire 23 changes accordingly.

[0021] The roller 22 is equipped with a vibration generator 22b that generates vibrational force used for compaction work, and compacts the ground by rotating while vibrating. The roller 22 is connected to the front wheel holder 21a via a vibration damping device 22a. By providing the vibration damping device 22a between the roller 22 and the front wheel holder 21a, vibrations from the roller 22 are not transmitted to the vehicle body 10. An acceleration beacon 31 is installed on the roller 22. The acceleration beacon 31 is preferably installed in a position where it can easily detect the vibrational force generated by the vibration generator 22b, and is fixed directly to the vibration generator 22b using fixing means such as string, adhesive tape, or magnet.

[0022] The acceleration beacon 31 detects vibrations generated by the vibration generator 22b of the roller 22 and transmits radio waves upon detection of vibrations. The acceleration beacon 31 transmits radio waves, for example, when it detects an acceleration above a predetermined threshold. The threshold here should be such that it can distinguish between when the vibration generator 22b is generating vibrations and when it is not. As a result, the radio waves transmitted by the acceleration beacon 31 in this embodiment itself become vibration information indicating that vibrations are being generated in the roller 22. Alternatively, the acceleration beacon 31 (vibration detection means 4) may transmit radio waves regardless of the presence or absence of vibrations, and may indicate the presence or absence of vibrations by changing the content of the transmitted signal.

[0023] As shown in Figure 2, the vibratory roller 1 is equipped with a beacon radio wave receiver 33 that receives radio waves (vibration information) transmitted by an acceleration beacon 31, which is a transmitter. In other words, the vibratory roller 1 is equipped with an acceleration beacon 31, which is a transmitter, and a beacon radio wave receiver 33, which is a receiver. The beacon radio wave receiver 33 is wired to a control device 34 and is installed, for example, inside the cockpit 11. The beacon radio wave receiver 33 can convert the radio waves (vibration information) received from the acceleration beacon 31 into data of a predetermined protocol and transmit the converted data to the control device 34.

[0024] The beacon radio wave receiver 33 has a function to measure radio wave intensity (RSSI) and can measure the radio wave intensity transmitted by the acceleration beacon 31. For example, when the beacon radio wave receiver 33 detects a radio wave intensity above a predetermined threshold, it transmits vibration information to the control device 34. In this embodiment, when focusing on one vibratory roller 1, the distance between the acceleration beacon 31, which is the transmitter, and the beacon radio wave receiver 33, which is the receiver, remains constant, so the radio wave intensity of the radio waves received by the beacon radio wave receiver 33 is always above a predetermined value. Therefore, even if multiple vibratory rollers 1 are working at the work site, it is difficult to confuse the radio waves transmitted by acceleration beacons 31 attached to other vibratory rollers 1 with the radio waves transmitted by the acceleration beacon 31 attached to one's own vibratory roller 1. Note that the acceleration beacon 31 may be managed by ID (identification information), in which case the beacon radio wave receiver 33 receives radio waves containing, for example, the ID (identification information). This method also makes it possible to identify the source of the radio waves.

[0025] The signal receiving device 32 shown in Figure 2 is a device that receives radio waves transmitted from a positioning satellite (not shown). The positioning satellite is a satellite used in the Global Navigation Satellite System (GNSS) and periodically transmits its own position information (orbital position information) and time information. Positioning satellites may be, for example, GPS (Global Positioning System) satellites, GLONASS (Global Navigation Satellite System) satellites, Galileo satellites, or quasi-zenith satellites. The signal receiving device 32 is wired to the control device 34 and is installed, for example, inside the cockpit 11. The signal receiving device 32 receives orbital position information and time information from the positioning satellite via its antenna and calculates its own position using the received orbital position information and time information. The method of calculating the position is not particularly limited, but it is preferable to use, for example, RTK (Real Time Kinematic), which can obtain highly accurate position information. The signal receiving device 32 then transmits the calculated position information to the control device 34. Alternatively, instead of positioning satellites, a total station or SLAM (Simultaneous Localization And Mapping) can be used to determine the position of the vibrating roller 1. In other words, various techniques can be used to determine the position of the vibrating roller 1.

[0026] The control device 34 is wired to the signal receiving device 32, the beacon radio wave receiving device 33, and the internet communication device 35. The control device 34 receives vibration information detected by the acceleration beacon 31 from the beacon radio wave receiving device 33, and also receives location information calculated from the signal receiving device 32. The control device 34 transmits the received vibration information and location information to the cloud system 2 via the internet communication device 35. The control device 34 may transmit the vibration information and location information in real time, or it may transmit information for a specific time period all at once. The control device 34 transmits the vibration information and location information to the cloud system 2 in association with each other. The method of associating the vibration information and location information is not particularly limited. In this embodiment, the control device 34 transmits only the location information acquired during the time period when the acceleration beacon 31 is emitting radio waves to the cloud system 2. As a result, the location information transmitted from the vibrating roller 1 in this embodiment is itself information in which vibration information is associated with location information. Furthermore, if the acceleration beacon 31 (vibration detection means 4) transmits radio waves regardless of whether or not there is vibration, the control device 34 associates the vibration information with the location information, for example, using the time. The control device 34 then transmits the vibration information and location information, which have been associated using the time, to the cloud system 2.

[0027] The acceleration beacon 31 (vibration detection means 4), signal receiving device 32 (position detection means 5), beacon radio wave receiving device 33, and control device 34 are collectively referred to as the "position acquisition system 200". The position acquisition system 200 outputs position information acquired during the time period when the vibration force generated during compaction work is detected by the vibration detection means 4. The position acquisition system 200 is preferably configured to be retrofitted to a general-purpose vibratory roller sold on the market.

[0028] As shown in Figure 2, the cloud system 2 comprises a storage unit 2a and an information organization unit 2b. The information organization unit 2b stores vibration information and location information in association with each other in the storage unit 2a. In this embodiment, since only location information acquired during the time when the acceleration beacon 31 is transmitting radio waves is acquired, the information organization unit 2b stores all location information received from the vibrating roller 1 in the storage unit 2a. The location information of the vibrating roller 1 stored in the storage unit 2a is associated with the passage of time, and the travel trajectory of the vibrating roller 1 can be determined by tracing the location information based on the passage of time. If the association between vibration information and location information is made by time, it is preferable for the information organization unit 2b to store the location information in the storage unit 2a in a manner that allows for the distinction between location information during the time when the roller 22 is generating vibrations and location information during other time periods.

[0029] The construction progress management device 3 shown in Figure 2 is a device for managing construction progress and is operated, for example, by the construction manager. The construction progress management device 3 may be a PC (Personal Computer), a portable terminal (for example, a mobile terminal or smartphone), etc. As shown in Figure 2, the construction progress management device 3 comprises a construction progress information creation unit 3a and a construction progress display processing unit 3b. The construction progress information creation unit 3a and the construction progress display processing unit 3b are realized, for example, by a CPU (Central Processing Unit) executing a construction progress management application program stored in ROM (Read Only Memory), etc.

[0030] The construction progress information creation unit 3a acquires location information obtained during the time period when the acceleration beacon 31 is transmitting radio waves, and creates construction progress information related to the construction progress. In this embodiment, the construction progress information creation unit 3a acquires the location information of the vibratory roller 1 via the cloud system 2, but the location information may also be acquired directly from the vibratory roller 1. The construction progress information is, for example, a representation of the completed area where compaction work has been completed as a surface shape. The construction progress information creation unit 3a creates a completed area K where compaction work has been completed, as shown in Figure 4, for example, by adding the width information of the vibratory roller 1 to the travel trajectory of the vibratory roller 1. Figure 4 is an image of the completed area K as construction progress information.

[0031] Furthermore, the construction progress information creation unit 3a may create progress management information that reflects the completed construction area K in the earthwork design information. An image of the progress management information is shown in Figure 5. The progress management information 9 shown in Figure 5 reflects the completed construction area K in the design information J. The design information J shown in Figure 5 has a three-layer structure: the lowest layer, the middle layer, and the uppermost layer, and the embankment is constructed in order from the bottom layer. Figure 5 shows the state where construction has been completed up to the middle layer. In other words, the completed construction area K1, where compaction work has been completed, is reflected on the top surface of the lowest layer. The completed construction area K2a, where compaction work was completed on "7 / 1", the completed construction area K2b, where compaction work was completed on "7 / 2", and the completed construction area K2c, where compaction work was completed on "7 / 3", are reflected on the top surface of the middle layer. Some areas of the middle layer (the area to the right of completed construction area K2c) have not been constructed yet, so the completed construction area K is not reflected there, and the completed construction area K will be reflected after construction is completed. Similarly, the top surface of the uppermost layer does not reflect the completed area K because no construction has been carried out there; the completed area K will be reflected after construction is completed. Note that progress management information 9 is an example of completed work information because it includes the completed area K.

[0032] The progress display processing unit 3b shown in Figure 2 has the function of displaying progress information. The progress display processing unit 3b may display the progress information on its own display unit (not shown), or it may transmit the progress information to another device (not shown) and have it displayed on the display unit of that other device. For example, the progress display processing unit 3b displays the progress management information 9 shown in Figure 5 on its display unit. This makes it possible to grasp the progress of earthwork at a glance.

[0033] ≪Operation of the construction progress management system according to this embodiment≫ Referring to Figure 6 (and Figures 1 to 3 as appropriate), the operation of the construction progress management system 100 according to the embodiment (construction progress management method) will be described. Figure 6 is an example of a flowchart showing the steps of the construction progress management method in the construction progress management system 100 according to the embodiment.

[0034] The signal receiving device 32 (position detection means 5) of the vibrating roller 1 calculates position information using the received positioning signal and transmits this position information to the control device 34 (step S1). The acceleration beacon 31 (vibration detection means 4) of the vibrating roller 1 determines whether the vibration acceleration detected by the acceleration sensor is above a threshold (step S2). The acceleration beacon 31 does not transmit radio waves (vibration information) if the vibration acceleration is not above the threshold (step S3). In this case, the control device 34 will only acquire position information (it will not acquire vibration information at the time it acquires position information). Therefore, the control device 34 determines that it does not need to record the position information and does not transmit the position information acquired from the signal receiving device 32 to the cloud system 2 (step S7).

[0035] If the vibration acceleration is above the threshold in step S2 (Yes in step S2), the acceleration beacon 31 (vibration detection means 4) transmits radio waves (vibration information), and the beacon radio wave receiver 33 receives the radio waves (vibration information) (step S4). The beacon radio wave receiver 33 determines whether the RSSI of the received radio waves (vibration information) is above the threshold (step S5), and if the RSSI of the radio waves (vibration information) is not above the threshold, it determines that the radio waves were not transmitted from the acceleration beacon 31 (vibration detection means 4) of the aircraft (step S6). In this case, the beacon radio wave receiver 33 does not transmit vibration information to the control device 34, and the control device 34 only acquires location information (it does not acquire vibration information at the time it acquires location information). Therefore, the control device 34 determines that it does not need to record location information and does not transmit the location information acquired from the signal receiver 32 to the cloud system 2 (step S7).

[0036] If the RSSI is above the threshold in step S5 (Yes in step S5), the beacon radio wave receiver 33 transmits electro-vibration information to the control device 34, and the control device 34 acquires location information and vibration information (vibration information is acquired at the same time as location information). Therefore, the control device 34 determines to record the location information and transmits the location information acquired from the signal receiver 32 to the cloud system 2 (step S8). The processes in steps S1 to S8 are executed repeatedly. As a result, the control device 34 transmits only the location information acquired during the time when the acceleration beacon 31 is transmitting radio waves to the cloud system 2. The location information transmitted from the vibrating roller 1 is itself information in which vibration information is associated with the location information.

[0037] The information organization unit 2b of the cloud system 2 stores the location information received from the vibratory roller 1 in the storage unit 2a. The construction progress information creation unit 3a of the construction progress management device 3 obtains location information acquired from the cloud system 2 during the time when the acceleration beacon 31 is transmitting radio waves, and creates construction progress information related to the construction progress. The construction progress display processing unit 3b displays the construction progress information created by the construction progress information creation unit 3a on the display unit.

[0038] As described above, the construction progress management system 100 according to the embodiment can determine the vibration state of the vibratory roller 1 and acquire position information. Here, in general, earthwork involves transporting soil with dump trucks, spreading the soil with bulldozers, and finally compacting it with a vibratory roller to finish the job. Therefore, knowing the position information of the vibratory roller is equivalent to measuring the construction progress. In addition, although the vibratory roller moves around the construction site in addition to compaction, it moves in a vibrating state only when compaction is being performed. Therefore, by associating the presence or absence of vibration of the vibratory roller with position information, it is possible to eliminate position information that is unnecessary for construction progress management. As a result, it becomes possible to automate daily construction progress management without requiring any special work processes. Furthermore, the acceleration beacon 31 can be added later and is easy to install. Therefore, as in this embodiment, by using the acceleration beacon 31 as the vibration detection means 4, it is possible to easily obtain positional information of the vibrating roller 1 when it is vibrating.

[0039] While embodiments of the present invention have been described so far, the present invention is not limited thereto and can be implemented without changing the spirit of the claims. For example, in this embodiment, an acceleration beacon 31 was assumed as the vibration detection means 4. However, the vibration detection means 4 is not limited to an acceleration beacon 31; for example, vibration information may be detected from a button that turns the vibration generator 22b ON / OFF or from its signal.
