Description

[Technical field]

[0001] The present invention relates to a progress management system, a processing device, a program, and a progress management method. [Background technology]

[0002] In recent years, technological developments for managing the progress of construction work have been actively conducted in order to improve the work efficiency of construction work. For example, if the location and operation status of construction machinery used in construction work can be confirmed in real time, the progress of construction work can be managed. Here, for outdoor construction work, the location of outdoor construction machinery can be obtained by GPS (Global Positioning System) or GNSS (Global Navigation Satellite System). In addition, the operation status of outdoor construction machinery can be obtained by a camera that captures the outdoor work site. However, since radio waves from satellites do not reach inside tunnels, the location of construction machinery inside tunnels cannot be obtained by GNSS or the like. In addition, in a closed environment such as inside a tunnel, even if many cameras are installed, the shooting range of the cameras is limited, so it is difficult to reliably obtain the operation status of indoor construction machinery.

[0003] Patent Document 1 discloses a tunnel construction process recording device that can quickly record the tunnel construction process at any time without relying on manual work. The invention in Patent Document 1 acquires electricity usage information such as the ON / OFF status of electricity usage and the amount of electricity from a power source such as a distribution board that supplies power to multiple machines, and determines the corresponding tunnel construction process by analyzing the acquired electricity usage information. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6942553 Summary of the Invention [Problem to be solved by the invention]

[0005] The invention of Patent Document 1 relates to the ON / OFF state of a machine's power supply to the work the machine is performing, and determines the operating status of the construction machine inside the tunnel. However, for example, even if the machine is powered on, there are cases where the machine is not performing construction work, so it cannot be said that the operating status of the construction machine can be managed accurately. In addition, there is a limit to determining the operating status only by the ON / OFF state of the power supply. For this reason, there is a problem that it is not possible to improve the work efficiency of tunnel construction.

[0006] From this perspective, an object of the present invention is to propose a progress management system, a processing device, a program, and a progress management method that improve the work efficiency of construction work. [Means for solving the problem]

[0007] The present invention, which solves the above problem, is a progress management system comprising a transmitter attached to a work machine, a receiver that receives radio waves from the transmitter, and a processing device that is communicatively connected to the receiver, the processing device comprising an analysis unit that analyzes the radio waves received by the receiver, and a judgment unit that judges the current work content based on the analysis results of the analysis unit and cycle information that indicates the work procedures for construction work. The present invention also relates to a processing device that is communicatively connected to a receiver that receives radio waves from a transmitter attached to a work machine, and that is equipped with an analysis unit that analyzes the radio waves received by the receiver, and a judgment unit that judges the current work content based on the analysis results of the analysis unit and cycle information that indicates the work procedures of a construction work. The present invention is also a program for causing a computer of a processing device, which is communicatively connected to a receiver that receives radio waves from a transmitter attached to a work machine, to function as an analysis unit that analyzes the radio waves received by the receiver, and a judgment unit that judges the current work content based on the analysis results of the analysis unit and cycle information that indicates the work procedures of construction work. The present invention also provides a progress management method comprising: a receiving step in which a receiver receives radio waves from a transmitter attached to a work machine; an analysis step in which a processing device communicatively connected to the receiver analyzes the radio waves received by the receiver; and a determination step in which the processing device determines the current work content based on the analysis results of the analysis step and cycle information indicating the work procedures of the construction work. According to this configuration, for example, by including the ID of the work machine in the radio waves transmitted from the transmitter, when the receiver analyzes the received radio waves, the working work machine can be determined as the analysis result. Also, since the role of each work machine is roughly determined, once the work machine can be determined, the current work content can be determined by checking it against a predetermined work procedure. Therefore, the progress of the construction work can be managed, and the work efficiency of the construction work can be improved by appropriately controlling the work machine according to the progress.

[0008] In addition, if the radio waves received by the receiver are from a transmitter attached to a work machine that performs multiple types of work, it is preferable that the judgment unit judges the current work content based on the judged previous work content. According to this configuration, the current work content can be uniquely identified. For example, for a breaker that performs hit-taking and scraping in tunnel construction, if it is determined that the scraping, which is performed before the hit-taking, was performed in the previous stage, the current work content can be determined as hit-taking. Also, if it is determined that the secondary spraying, which is performed before the scraping, was performed in the previous stage, the current work content can be determined as scraping.

[0009] It is also preferable that the cycle information has a priority set for each work content, and when the receiver receives radio waves from each of multiple types of transmitters attached to each of multiple types of work machines, the determination unit determines that the work content with the highest priority among the multiple types of work content determined based on the analysis result and the cycle information is the current work content. According to this configuration, the current work content can be uniquely identified. For example, if an explosives carrier is transporting explosives while a rock drill is drilling a hole, it is not possible to immediately determine whether the current work content is drilling or explosives loading. However, if the priority of drilling is set higher than the priority of explosives loading in the cycle information, the current work content can be determined to be drilling.

[0010] It is preferable that the processing device further includes a display control unit that causes a display device to display a task time for each task content based on a determination result by the determination unit. According to this configuration, by continuing to judge the current task content, the task time for each task content can be made apparent, and therefore the progress of each task content can be easily managed. It is also preferable that the display control unit causes the display device to display the divided working time into actual working time and non-actual working time. According to this configuration, the contribution of the work machine can be made apparent, and the progress of each work item can be easily managed. Effect of the Invention

[0011] According to the present invention, the work efficiency of construction work can be improved. [Brief description of the drawings]

[0013] Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings. Each drawing is merely a schematic illustration to allow a sufficient understanding of the present invention. Therefore, the present invention is not limited to the illustrated examples. In each drawing, common or similar components are denoted by the same reference numerals, and duplicated explanations thereof will be omitted.

[0014] [composition] Fig. 1 is a functional configuration diagram of a progress management system of this embodiment. The progress management system is a system for managing the progress of construction work inside a tunnel. The progress management system comprises a processing device 1, a display device 2, multiple types of beacons 3, multiple receivers 4, and a camera 5. The processing device 1 is a computer that performs processing for monitoring a work machine 6 used in the construction work of a tunnel. The display device 2 is a device that displays the processing results of the processing device 1. The display device 2 can also function as a console for the processing device 1.

[0015] The processing device 1, the display device 2, the beacon 3, the receiver 4, and the camera 5 are connected to each other via a network so as to be able to communicate wirelessly or with a wire. The network may be, for example, the Internet, but is not limited thereto. For example, communication via the network may be realized by implementing relay devices (not shown) such as a router, mesh, or bridge.

[0016] The processing device 1 includes hardware such as an input unit, an output unit, a control unit, and a storage unit. For example, if the control unit is configured with a CPU (Central Processing Unit), information processing by a computer including the control unit is realized by program execution processing by the CPU. Also, the storage unit included in the computer stores various programs for realizing the functions of the computer according to instructions from the CPU. This realizes collaboration between software and hardware. The programs can be provided by recording them on a recording medium or via a network.

[0017] The beacon 3 is a transmitter that is attached to the work machine 6 and transmits radio waves for wireless communication. The beacon 3 in this embodiment may be an acceleration type beacon 3a attached to the work machine 6 or a power supply type beacon 3b attached to the work machine 6, but is not limited to these.

[0018] The acceleration-type beacon 3a detects vibrations that occur when the work machine 6 operates to perform a specified task, and emits radio waves when the detection of the vibrations is used as a trigger. For example, the beacon 3a is preferably affixed to a specified location on the work machine 6. The beacon 3a is equipped with an acceleration sensor, and emits radio waves when acceleration equal to or greater than a predetermined threshold is detected.

[0019] The power-supply type beacon 3b detects power supply when the power supply of the working machine 6 is turned on, and transmits radio waves when the detection of power supply is used as a trigger. The power-supply type beacon 3b detects no power supply when the power supply of the working machine 6 is turned off, and stops transmitting radio waves when the detection of no power supply is used as a trigger. For example, it is preferable that the beacon 3b is inserted into a power supply port provided in the working machine 6 to directly detect power supply. Alternatively, the beacon 3b may be inserted into a socket of a power supply control box that supplies power to the working machine 6 to indirectly detect power supply. Note that when the beacons 3a and 3b are not differentiated, or when other types of beacons are also included, they will be described as beacon 3.

[0020] The receiver 4 is a device that receives radio waves from the beacon 3. Each of the multiple receivers 4 is arranged at a predetermined interval in the direction from the tunnel face to the tunnel mouth, and can be attached to the inner wall of the tunnel, for example. The receiver 4 can convert the radio waves received from the beacon 3 into data of a predetermined protocol, and transmit the converted data to the processing device 1 via a network. The data received by the processing device 1 includes, but is not limited to, information about the radio waves received by the receiver 4 and an ID that identifies the receiver 4 that received the radio waves. In addition, the information about the radio waves is, for example, an ID that identifies the beacon 3 that transmitted the radio waves, but is not limited to this.

[0021] The camera 5 is an imaging device that captures images of the work machine 6 working inside the tunnel. The camera 5 is disposed inside the tunnel, and is preferably disposed in a position and orientation that allows it to capture an image of the tunnel face.

[0022] The working machines 6 are, for example, face drilling machines (drill jumbos) used in mountain tunnel construction, explosives transport vehicles, power supply dollies, wheel loaders, breakers, concrete sprayers, mortar pumps, dump trucks, truck mixers, backhoes, etc. By monitoring these working machines 6 used in tunnel construction work, the progress of tunnel construction work (including mountain tunnel construction) can be managed in detail, and the work efficiency of tunnel construction work can be further improved.

[0023] (Software configuration of processing device 1) The processing device 1 includes an analysis unit 11, a determination unit 12, and a display control unit 13. The processing device 1 also stores a transmitter DB 21, a receiver DB 22, an operation information DB 23, related information 24, and cycle information 25. "DB" is an abbreviation for database.

[0024] The analysis unit 11 can analyze the radio waves received from the beacon 3 by processing the data received from the receiver 4. When the beacon 3 is an acceleration type beacon 3a, the radio waves transmitted by the beacon 3a are radio waves caused by the vibration of the work machine 6. For example, the radio waves transmitted by the beacon 3a may be radio waves having a waveform that follows the waveform of the acceleration of the work machine 6. Alternatively, the radio waves may have a predetermined waveform (e.g., a sine wave) and the frequency may change in response to the vibration (acceleration). Alternatively, the radio waves may show a constant waveform (frequency and amplitude are constants) when the acceleration (vibration) exceeds a predetermined value.

[0025] The analysis of the radio waves by the analysis unit 11 may be, for example, an analysis that the work machine 6 is operating because the beacon 3 is transmitting radio waves. The analysis unit 11 may perform a Fourier transform to analyze the characteristics of the frequency contained in the radio waves. The analysis unit 11 may obtain the strength (amplitude) of the radio waves received by the receiver 4, and identify the position of the work machine 6 or the operating state of the monitored object based on the obtained strength. The analysis unit 11 may also identify the ID of the beacon 3 that transmitted the radio waves, thereby identifying the ID of the work machine 6 to which the beacon 3 is attached.

[0026] The determination unit 12 determines the current work content based on the analysis results of the analysis unit 11 and cycle information 25 indicating the work procedure of the construction work. The display control unit 13 causes the display device 2 to display the task time for each task based on the determination result of the determination unit 12.

[0027] The transmitter DB 21 stores transmitter information, which is information related to the beacon 3, for each beacon 3. The transmitter information includes, for example, but is not limited to, an ID for identifying the target beacon 3, a type of the beacon 3 (acceleration type, power supply type, etc.), and an ID for identifying the work machine 6 to which the beacon 3 is attached. The radio waves transmitted from the beacon 3 include the ID for identifying the beacon 3.

[0028] The analysis unit 11 can refer to the transmitter DB 21 and identify an ID for identifying the work machine 6 to which the beacon 3 is attached from the radio waves received by the receiver 4. The radio waves transmitted from the beacon 3 may include an ID for identifying the work machine 6 to which the beacon 3 is attached. The processing device 1 can refer to a predetermined database (not shown) using the ID for identifying the work machine 6 and identify the type of work machine 6 (e.g., dump truck, hydraulic excavator, jumbo) and the work content that the work machine 6 can perform (e.g., driving rock bolts in the case of a jumbo).

[0029] The receiver DB22 stores receiver information, which is information related to the receiver 4, for each receiver 4. The receiver information includes, but is not limited to, for example, an ID for identifying the target receiver 4, the position of the receiver 4, and a threshold value for the strength of the radio waves received by the receiver 4. The position of the receiver 4 can be specified, for example, as well-known map information. The threshold value for the strength of the radio waves is a value that can be used for analysis by the analysis unit 11, and can be set by an operator of the processing device 1. For example, radio waves with a strength below the threshold can be cut off as noise. Furthermore, when the receiver 4 receives radio waves with a strength above the threshold, the analysis unit 11 can identify the receiver 4 and the beacon 3 that transmitted the radio waves, and analyze the radio waves. Multiple threshold values ​​can be set.

[0030] The operation information DB 23 stores operation information of the work machine 6 for each work machine 6. The operation information of the work machine 6 is information generated as an analysis result by the analysis unit 11. The operation information of the work machine 6 includes, for example, but is not limited to, the operation status of the work machine 6, an ID for identifying the receiver 4 that received radio waves from the beacon 3 attached to the work machine 6, an ID for identifying the work machine 6, the ID of the beacon 3 attached to the work machine 6, and the time of radio wave reception.

[0031] The operation state of the working machine 6 is information indicating whether the working machine 6 is operating (working) or not. Furthermore, if the beacon 3 is an acceleration type beacon 3a, the operation information of the working machine 6 can include the work content, work time, work start time, and work end time of the working machine 6. Furthermore, if the beacon 3 is a power supply type beacon 3b, the operation information of the working machine 6 can include the power supply time, power supply start time, and power supply end time of the working machine 6. The information in the transmitter DB 21, the receiver DB 22, and the operation information DB 23 are associated with each other.

[0032] The related information 24 is information that associates the work content performed in tunnel construction with one type of work machine 6 that performs the work content. When a specific work machine 6 is operating, the determination unit 12 can determine that the work content associated with the related information 24 is the current work content. There are cases where multiple types of work machines 6 are operating for the same work content. In this case, the analysis unit 11 can generate multiple types of operation information for the operating work machines 6, and the determination unit 12 can determine that the work content associated with the work machine 6 indicated by the generated operation information is the current work content by referring to the related information 24. It is preferable that the work machine 6 registered in the related information 24 is the work machine 6 that is always operating when the associated work content is being performed.

[0033] In this embodiment, the association between the work content (left side) and the work implement 6 (right side) registered in the association information 24 is as follows, but the association is not limited to this. Drilling...Jumbo Drill Explosives...Explosives transport car Blasting...Power supply trolley Dislodgement...Wheel loader Hitting...Breaker Primary spraying...spraying machine Shoring construction··Spraying machine Secondary spraying...spraying machine Cleaning · Breaker Rock bolts · Mortar pumps

[0034] Cycle information 25 is information showing the work procedure of tunnel construction. One cycle of tunnel construction proceeds, for example, as follows: drilling → charging → blasting → excavation → hit collection → primary spraying → shoring construction → secondary spraying → scraping → rock bolting (sometimes written as "RB"), and the cycle is repeated. These work contents can be selected or changed in order as appropriate, taking into consideration various circumstances such as the location of the tunnel construction and the nature of the ground. The related information 24 and the cycle information 25 can be input in advance to the processing device 1, and the contents can be changed as appropriate (for example, secondary spraying is not performed).

[0035] Fig. 2 is an example of an input screen for cycle information. For example, the display control unit 13 of the processing device 1 can cause the display device 2 to display the screen of Fig. 2. A user of the display device 2 can set cycle information 25 via the screen of Fig. 2. The screen of Fig. 2 can provide columns for "task content", "priority", "color", "area", "starting point", "previous task conditions", and "duration".

[0036] In the "Work content" column, the work content to be performed in the tunnel construction is registered, and the name of the work content is displayed. The work procedure shown in the cycle information 25 corresponds to the registration order of the work content registered in the "Work content" column. In the "priority" column, the priority set for each work content is registered and the priority value is displayed. When the receiver 4 receives radio waves from each of the multiple types of beacons 3 attached to each of the multiple types of work machines 6, the determination unit 12 can determine that the work content with the highest priority among the multiple types of work contents determined based on the analysis result of the analysis unit 11 and the cycle information 25 is the current work content.

[0037] In the "Color" column, the color to be used to display the work content on the display device 2 is registered, and a sample color is displayed. For convenience of illustration, in this embodiment, differences in color are displayed by differences in hatching. The "Area" column registers the location where the work is performed, and displays the name of the location. For example, since hole drilling is performed at the tunnel face, if "Hole Drilling" is registered in the "Work" column, "Face" is registered in the "Area" column. The location registered in the "Area" column can be selected from options in a pull-down menu. For example, the options can provide information indicating the location of the receiver 4 placed inside the tunnel. "Face" represents information indicating the location of the receiver 4a closest to the tunnel face.

[0038] In the "Starting point" field, the work content that is the starting point of one cycle indicated by the cycle information 25 is registered and displayed. The work content registered in the "Starting point" field can be selected by enabling one of the radio buttons prepared for each work content. As shown in Fig. 2, if blasting is selected as the starting point, the work in one cycle of tunnel construction can be blasting → excavation → hit collection → primary spraying → erection of shoring → secondary spraying → scraping → rock bolting → drilling → charging.

[0039] In the "Previous Work Conditions" field, if there is a setting from the user of the display device 2, the previous work content of the target work content is registered and the name of the previous work content is displayed. If the radio wave received by the receiver 4 is a radio wave from a beacon 3 attached to a work machine 6 that performs multiple types of work, the determination unit 12 can determine the current work content based on the determined previous work content.

[0040] The previous work conditions serve to narrow down the current work contents, which can be estimated from a number of types, by the operation of a specific work machine 6. The work contents registered in the "previous work conditions" field can be selected from options in a pull-down menu. For example, the options can include work contents registered in the cycle information 25.

[0041] The "Duration" column registers and displays the time allocated to the target work content whose previous work content is registered in the "Previous Work Conditions" column as the duration. The duration plays the role of the expected completion time of the target work content. If the receiver 4 receives radio waves from the beacon 3 of the work machine 6 associated with the target work content in the related information 24 after the determined previous work content, the determination unit 12 determines that the current work content is the target work content.

[0042] In this case, if radio wave reception by receiver 4 ends before the end of the duration, the work time for the target work content will be the time from the end of the previous work content to the end of radio wave reception by receiver 4. Conversely, if radio wave reception by receiver 4 ends after the end of the duration, the work time for the target work content will be the time from the end of the previous work content to the end of the duration.

[0043] The work content to be registered in the "Duration" field can be selected from options in a pull-down menu. For example, the options can be prepared in units of one hour. As shown in FIG. 2, in the case where "Drilling" is registered in the "Previous Work Condition" field and "2 hours" is registered in the "Duration" field for the work content of "Loading", if the determination unit 12 determines that some work content has been performed within two hours since the end of drilling, the determination unit 12 can determine that some work content is loading, and determine that loading is continuing as the current work content.

[0044] (Details of work content judgment) The determination of the work content by the determination unit 12 will be described in detail for each work content. [Work: Drilling] In determining whether or not a hole is to be drilled, for example, a rock drill equipped in a drill jumbo can be used. The rock drill equipped with an acceleration type beacon 3a performs hole drilling (blasting hole drilling) on ​​the face. The beacon 3a then detects the vibration of the rock drill and transmits radio waves. The transmitted radio waves include the ID of the rock drill beacon 3a. When the receiver 4a receives the radio waves from the rock drill beacon 3a, it transmits data including the ID of the rock drill beacon 3a to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the rock drill beacon 3a. The determination unit 12 of the processing device 1 can determine that the current work content is hole drilling based on the analysis result of the analysis unit 11 and the cycle information 25.

[0045] The water pump equipped on the drill jumbo may also be used to determine the hole drilling. The water pump sprays water on the face to promote rock drilling and suppress dust generated during hole drilling. For work reasons, the water pump is turned off except when drilling. A powered beacon 3b is then attached to the water pump to prepare for hole drilling (blasting hole drilling). When the water pump is turned on, the beacon 3b transmits radio waves upon detecting power supply. The transmitted radio waves contain the ID of the water pump's beacon 3b.

[0046] When the receiver 4a receives radio waves from the water pump beacon 3b, it transmits data including the ID of the water pump beacon 3b to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the water pump beacon 3b. Based on the analysis result of the analysis unit 11 and the cycle information 25, the determination unit 12 of the processing device 1 can determine that the current work content (preparation for) is hole drilling.

[0047] [Work: Loading] For example, an explosives carrier that carries explosives can be used to determine whether explosives are loaded. The explosives carrier, to which an acceleration-type beacon 3a is attached, moves to the face. The beacon 3a then detects the vibration of the explosives carrier and transmits radio waves. The transmitted radio waves include the ID of the beacon 3a of the explosives carrier. When the receiver 4a receives radio waves from the beacon 3a of the explosives carrier, it transmits data including the ID of the beacon 3a of the explosives carrier to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the beacon 3a of the explosives carrier. The determination unit 12 of the processing device 1 can determine that the current work content is explosives loading based on the analysis result of the analysis unit 11 and the cycle information 25.

[0048] Here, explosives cannot be loaded before drilling is completed, but explosives are transported even during drilling. Therefore, the receiver 4a simultaneously receives radio waves from the beacon 3a of the drill jumbo's rock drill machine and the beacon 3a of the explosives carrier, and the judgment unit 12 can judge the current work content as either drilling or explosives loading. It is not appropriate to judge the current work content as explosives loading by monitoring only the explosives carrier.

[0049] Therefore, the analysis unit 11 analyzes the radio waves from the beacon 3a of the explosives carrier to obtain the face entry / exit information of the explosives carrier. The face entry / exit information is information indicating the time from the arrival time at the face to the departure time from the face. The arrival time corresponds to the start time of reception of the radio waves at the receiver 4a. The departure time corresponds to the end time of reception of the radio waves at the receiver 4a. The end time of drilling, that is, the end time of reception of the radio waves from the beacon 3a of the drill jumbo rock drilling machine at the receiver 4a, is included in the time indicated by the face entry / exit information of the explosives carrier. Therefore, when the radio waves are received from the beacon 3a of the explosives carrier after the end time of drilling, the determination unit 12 can determine that the work content after the end time of drilling is charging. Also, the determination unit 12 can determine that the work content during the time from the arrival time of the explosives carrier at the face to the end time of drilling is drilling.

[0050] The determination by the determination unit 12 is based on the fact that "hole drilling" is set as the work content preceding "charge loading" in the cycle information 25 (see "hole drilling" set in the "previous work condition" field of "charge loading" in the example screen of FIG. 2). In other words, when the determination unit 12 determines that the work is a preceding work of hole drilling, it determines that the work is a charge loading.

[0051] [Work: Blasting] During blasting, large vibrations occur inside the tunnel. Therefore, a method of judging that blasting has occurred can be considered by installing an acceleration sensor inside the tunnel and determining that blasting has occurred if the acceleration sensor detects acceleration after the charging work. However, this judgment method is not optimal because there is a possibility of false detection due to flying stones caused by blasting touching the acceleration sensor. Therefore, for example, a power supply cart that follows the face and supplies power to the blasting operating device can be used to judge blasting.

[0052] A power supply cart equipped with an acceleration type beacon 3a moves to the face during blasting. The beacon 3a then detects the vibration of the power supply cart and transmits radio waves. The transmitted radio waves include the ID of the beacon 3a of the power supply cart. When the receiver 4a receives the radio waves from the beacon 3a of the power supply cart, it transmits data including the ID of the beacon 3a of the power supply cart to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the beacon 3a of the power supply cart. The judgment unit 12 of the processing device 1 can judge the current work content to be blasting based on the analysis result of the analysis unit 11 and the cycle information 25.

[0053] The determination by the determination unit 12 is based on the fact that "charge loading" is set as the work content prior to "blasting" in the cycle information 25 (see "charge loading" set in the "previous work conditions" field of "charge loading" in the example screen of FIG. 2). In other words, when the determination unit 12 determines that the work is charge loading in the prior stage, it determines that the work is blasting.

[0054] [Work: Pulling out] For example, a wheel loader can be used to determine whether or not the mine is being removed. The wheel loader, which is equipped with an acceleration-type beacon 3a, performs removal at the face of the mine. The beacon 3a then detects the vibration of the wheel loader and transmits radio waves. The transmitted radio waves include the ID of the beacon 3a of the wheel loader.

[0055] When the receiver 4a receives radio waves from the beacon 3a of the wheel loader, it transmits data including the ID of the beacon 3a of the wheel loader to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the beacon 3a of the wheel loader. The determination unit 12 of the processing device 1 can determine that the current work content is a shifting operation based on the analysis result of the analysis unit 11 and the cycle information 25.

[0056] [Work content: Winning] A breaker, for example, can be used to determine whether a breaker has been hit. A breaker equipped with an acceleration-type beacon 3a performs hit detection at the face. The beacon 3a then detects the vibration of the breaker and transmits radio waves. The transmitted radio waves include the ID of the breaker beacon 3a. When the receiver 4a receives the radio waves from the breaker beacon 3a, it transmits data including the ID of the breaker beacon 3a to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the breaker beacon 3a.

[0057] Here, the breaker is a general-purpose machine and is used for various purposes. In this embodiment, the breaker is used not only for hitting but also for scraping. Therefore, even if the analysis unit 11 analyzes the radio waves from the breaker beacon 3a, the determination unit 12 cannot determine whether the current work content is hitting or scraping.

[0058] Therefore, the previous work conditions in the cycle information 25 are used. In the example screen of Fig. 2, "shifting" is set in the "previous work conditions" column for "hit pick". Therefore, when the determination unit 12 of the processing device 1 determines that the previous stage is shifting, it can determine that the current work content is hit pick based on the analysis result of the analysis unit 11 and the cycle information 25.

[0059] [Work: Primary spraying] In determining the primary spraying, for example, a concrete pump provided in the sprayer can be used. Primary spraying is performed at the face using a concrete pump equipped with an acceleration type beacon 3a. The beacon 3a then detects vibrations of the concrete pump and transmits radio waves. The transmitted radio waves include the ID of the concrete pump beacon 3a. When the receiver 4a receives the radio waves from the concrete pump beacon 3a, it transmits data including the ID of the concrete pump beacon 3a to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the concrete pump beacon 3a.

[0060] Here, the concrete pump is used not only for primary spraying but also for secondary spraying. Therefore, even if the analysis unit 11 analyzes the radio waves from the beacon 3a of the concrete pump, the judgment unit 12 cannot judge whether the current work content is primary spraying or secondary spraying. Therefore, the previous work conditions of the cycle information 25 are used. In the example screen of FIG. 2, "sludge-out" is set in the "previous work conditions" column for "primary spraying". Therefore, when the judgment unit 12 of the processing device 1 judges that the current work content is sludge-out in the previous stage, it can judge that the current work content is primary spraying based on the analysis result of the analysis unit 11 and the cycle information 25.

[0061] In addition, in the judgment of the first spraying, "hit taking" may be set in the "previous work conditions" column, but "scraping" is preferable. Depending on the crushing situation due to blasting, the on-site decision may be made to omit hit taking. In this case, since radio waves are not transmitted from the beacon 3a of the breaker that performs the hit taking, the judgment unit 12 cannot judge the hit taking, which may lead to an error in the judgment of the "first spraying". Therefore, since the scuffing is performed reliably, by setting "scraping" in the "previous work conditions" column of "first spraying", it is possible to deal with the situation where hit taking is omitted.

[0062] [Work: Construction of shoring] In determining whether or not support work is installed, for example, a man gauge equipped in a spraying machine can be used. A magnetic beacon is used as the beacon 3 to be attached to the displaced portion of the man gauge. A magnet is also attached to the non-displaced portion of the man gauge. The man gauge to which the magnet and magnetic beacon are attached is used to install support work. Then, as the man gauge expands and contracts, the magnetic beacon detects the presence or absence of a magnet and transmits radio waves. The transmitted radio waves contain the ID of the magnetic beacon of the man gauge.

[0063] When the receiver 4a receives radio waves from the magnetic beacon of the man gauge, it transmits data including the ID of the magnetic beacon of the man gauge to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the magnetic beacon of the man gauge. The determination unit 12 of the processing device 1 can determine that the current work content is shoring construction based on the analysis result of the analysis unit 11 and the cycle information 25.

[0064] In addition, a method of detecting the extension or contraction of the man gauge may be a method of using a distance sensor that can emit radio waves according to the detected distance. The distance sensor is placed at a position where it can detect the distance between the base and tip of the man gauge. The distance sensor can emit radio waves when the man gauge extends by a predetermined amount or more. The emitted radio waves include the ID of the distance sensor. When the receiver 4a receives the radio waves from the distance sensor, it transmits data including the ID of the distance sensor to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs the analysis result including the ID of the distance sensor. The judgment unit 12 of the processing device 1 can judge that the current work content is shoring construction based on the analysis result of the analysis unit 11 and the cycle information 25.

[0065] [Work: Secondary spraying] In determining whether or not to perform secondary spraying, for example, a concrete pump provided in the sprayer can be used. Secondary spraying is performed at the face using a concrete pump equipped with an acceleration-type beacon 3a. The beacon 3a then detects vibrations of the concrete pump and transmits radio waves. The transmitted radio waves include the ID of the concrete pump beacon 3a. When the receiver 4a receives the radio waves from the concrete pump beacon 3a, it transmits data including the ID of the concrete pump beacon 3a to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the concrete pump beacon 3a.

[0066] Here, the concrete pump is used not only for secondary spraying but also for primary spraying. Therefore, even if the analysis unit 11 analyzes the radio waves from the beacon 3a of the concrete pump, the determination unit 12 cannot determine whether the current work content is secondary spraying or primary spraying.

[0067] Therefore, the previous work conditions in the cycle information 25 are used. In the example screen of Fig. 2, "shoring construction" is set in the "previous work conditions" column for "secondary spraying". Therefore, when the determination unit 12 of the processing device 1 determines that the work is to "shoring construction" in the previous stage, it can determine that the current work content is "secondary spraying" based on the analysis result of the analysis unit 11 and the cycle information 25.

[0068] [Work: Scraping] For example, a breaker can be used to determine whether or not cutting is performed. A breaker equipped with an acceleration type beacon 3a performs cutting at the face. The beacon 3a then detects the vibration of the breaker and transmits radio waves. The transmitted radio waves include the ID of the breaker beacon 3a. When the receiver 4a receives the radio waves from the breaker beacon 3a, it transmits data including the ID of the breaker beacon 3a to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs the analysis result including the ID of the breaker beacon 3a.

[0069] Here, the breaker is a general-purpose machine and is used for various purposes. In this embodiment, the breaker is used not only for scraping but also for hit-taking. Therefore, even if the analysis unit 11 analyzes the radio waves from the breaker beacon 3a, the determination unit 12 cannot determine whether the current work content is scraping or hit-taking.

[0070] Therefore, the previous work conditions in the cycle information 25 are used. In the example screen of Fig. 2, "secondary spraying" is set in the "previous work conditions" column for "scraping". Therefore, when the judgment unit 12 of the processing device 1 judges that the previous work is secondary spraying, it can judge that the current work content is scrubbing based on the analysis result of the analysis unit 11 and the cycle information 25.

[0071] [Work content:RB] In determining the RB, for example, a mortar pump equipped in a drill jumbo can be used. Mortar is injected into the RB drilling hole using a mortar pump equipped with an acceleration type beacon 3a. The beacon 3a then detects the vibration of the mortar pump and transmits radio waves. The transmitted radio waves include the ID of the mortar pump's beacon 3a.

[0072] When the receiver 4a receives radio waves from the mortar pump beacon 3a, it transmits data including the ID of the mortar pump beacon 3a to the processing device 1. The analysis unit 11 of the processing device 1 analyzes the data from the receiver 4a and outputs an analysis result including the ID of the mortar pump beacon 3a. The determination unit 12 of the processing device 1 can determine that the current work content is RB based on the analysis result of the analysis unit 11 and the cycle information 25.

[0073] (Visualization of work progress) The display control unit 13 of the processing device 1 can display the progress of work inside the tunnel on the display device 2 based on the determination result of the determination unit 12. This makes it possible to easily check the work progress of the work machine 6, and efficiently manage the work progress.

[0074] FIG. 3 is an example of a progress time chart screen. Face work carried out inside a tunnel progresses by repeating the work procedure shown in the cycle information 25. For example, if the time required to complete one cycle is 7.7 hours and the daily operating hours are 21.5 hours, approximately 2.79 cycles can be completed in one day. Also, if the face advances 1 m in one cycle, the face advances approximately 2.79 m in one day. The progress time chart in FIG. 3 visualizes the operating status of the working machine 6 participating in the face work on a daily basis.

[0075] The progress time chart in FIG. 3 has a "display name" column (left side) and a time chart column (right side). The "display name" column lists the names of the work machines 6 used on a specific work day (for example, the day before yesterday (2023 / 05 / 22)). However, the "cycle" listed at the top of the "display name" column does not indicate the name of the work machine, but rather indicates a collection of various work contents listed at the top of the time chart column.

[0076] The various work contents written in the top row of the time chart column are the work contents at each time point shown as the judgment result of the judgment unit 12, and are displayed in bands according to the colors registered in the "Color" column of the screen example in Fig. 2. Note that the list in the "Display Name" column is written for each beacon 3 attached to the work machine 6, not for each work machine 6.

[0077] As shown in Figure 3, the "Display Name" column contains the following items: "Jumbo", "Jumbo (additional)", "Rock Drill Left (60)", "Rock Drill Medium (60)", "Rock Drill Right (60)", "Spraying Machine", "Spraying Machine (additional)", "Building Detection (Right)", "Building Detection (Left)", "Tramiki [1]", "Tramiki [2]", "Wheel Loader", "0.7t Breaker", "3t Breaker", "0.7m 3 "BH(CAT)", "30tDT[1]", "30tDT[2]", "30tDT[3]", "Mortar Pump", "Mortar Cart", "Explosive Loading Device", "1t Explosive Transport Vehicle", "Explosive Loading Vehicle", "Explosive Charge Detection", and "Blasting Bi-electrode (100)". However, the descriptions in the "Display Name" column in FIG. 3 are examples, and the work machines 6 described in the "Display Name" column are not limited to these.

[0078] “Jumbo” indicates a power-supply type beacon 3 b attached to a drill jumbo, which is a work machine 6 registered in the related information 24 . “Jumbo (Canada)” indicates an acceleration type beacon 3 a attached to a drill jumbo, which is a work machine 6 registered in the related information 24 . “Rack Drill Left (60)”, “Rack Drill Middle (60)”, and “Rack Drill Right (60)” respectively indicate acceleration type beacons 3a attached to the left beam, center beam, and right beam of a rock drill equipped on a drill jumbo, which is a work machine 6 registered in the related information 24.

[0079] The "spraying machine" indicates a power-supplying beacon 3b attached to a spraying machine, which is a work machine 6 registered in the related information 24. “Spraying machine (addition)” indicates an acceleration-type beacon 3 a attached to a spraying machine, which is a work machine 6 registered in the related information 24 . “Installation detection (right)” and “Installation detection (left)” respectively indicate the magnetic beacons attached to the right man gauge and the left man gauge equipped on a spray machine as a work machine 6 registered in the related information 24.

[0080] "Truck mixer [1]" and "Truck mixer [2]" respectively indicate acceleration type beacons 3a attached to the truck mixer. In this embodiment, the truck mixer is not registered in the related information 24, so it is not used for the judgment of the judgment unit 12.

[0081] “Wheel loader” indicates an acceleration-type beacon 3 a attached to a wheel loader, which is a work machine 6 registered in the related information 24 . “0.7 t breaker” indicates an acceleration type beacon 3 a attached to a breaker serving as a work machine 6 registered in the related information 24 . “3t breaker” indicates an acceleration type beacon 3 a attached to a breaker serving as a work machine 6 registered in the related information 24 .

[0082] "0.7m 3 "BH(CAT)" indicates an acceleration type beacon 3a attached to a backhoe. In this embodiment, the backhoe is not registered in the related information 24, and therefore is not used in the determination by the determination unit 12. "30tDT[1]", "30tDT[2]" and "30tDT[3]" each indicate an acceleration type beacon 3a attached to a dump truck. In this embodiment, the dump truck is not registered in the related information 24, and therefore is not used in the determination by the determination unit 12.

[0083] "Mortar pump" indicates an acceleration type beacon 3a attached to a mortar pump equipped on a drill jumbo, which is registered in the related information 24. "Mortar cart" refers to the acceleration type beacon 3a attached to the mortar cart on which the mortar pump equipped in the drill jumbo is placed. In this embodiment, the mortar cart is not registered in the related information 24, and therefore is not used in the judgment of the judgment unit 12.

[0084] The "explosive loading device" refers to the acceleration type beacon 3a attached to an automatic explosive loading device arranged on the explosive beam equipped on the drill jumbo. In this embodiment, the explosive loading device is not registered in the related information 24, and therefore is not used for the judgment of the judgment unit 12. "1 ton explosives transport vehicle" is one type of explosives transport vehicle as the work machine 6 registered in the related information 24, and indicates the acceleration type beacon 3a attached to the explosives transport vehicle. The "explosive loading vehicle" is one type of explosive transport vehicle that serves as the work machine 6 registered in the related information 24, and indicates the acceleration type beacon 3a attached to the explosive transport vehicle.

[0085] "Charge detection" indicates a magnet beacon attached to the charge beam gauge of the drill jumbo. The charge beam gauge is not registered in the related information 24, so it is not used in the judgment of the judgment unit 12. “Blasting beacon ( 100 )” indicates an acceleration type beacon 3 a attached to a power supply cart serving as a work machine 6 registered in the related information 24 .

[0086] The time chart column shows the operating time period of the corresponding working machine 6 on a specific work day. More specifically, the operating time period during which the beacon 3 attached to the corresponding working machine 6 or its parts was activated by power supply or vibration detection and emitted radio waves is displayed in a band. The operating time period (operating time period) is obtained from the operation information generated by the analysis unit 11. The operating time period (operating time period) can be divided into a first operating time period indicating the time period during which work was performed at the tunnel face, and a second operating time period indicating the time period during which work was performed inside the tunnel shaft a predetermined distance away from the tunnel face.

[0087] In Fig. 3, the first operating time period is illustrated in dark grey, and the second operating time period is illustrated in light grey. The first operating time period can be determined based on operation information generated by the analysis unit 11 analyzing radio waves received by the receiver 4a closest to the face. The second operating time period can be determined based on operation information generated by the analysis unit 11 analyzing radio waves received by one or more receivers 4 other than receiver 4a (4b, etc.) that are located near the face.

[0088] When generating operation information of the work machine 6, the analysis unit 11 can identify the working time of the work content of the work machine 6 based on the transmission period of radio waves from the beacon 3 (the operation time of the beacon), that is, the reception period of radio waves by the receiver 4. In addition, as shown in Fig. 3, the display device 2 displays the operation information for each work machine 6, thereby making it possible to visualize the work status at the site.

[0089] The displayed operation information is not only the ON / OFF status of the power supply of the work machine 6, etc., but also indicates the work content specific to the work machine 6 corresponding to the vibration generated by the work machine 6. Therefore, the display device 2 can display the details of the work content performed by the work machine 6. It can also display the start time, end time, and working time for each work content. Therefore, the progress of construction work can be managed, and the work efficiency of the construction work can be improved.

[0090] In addition, by using a simple and inexpensive device such as a beacon 3 as a transmitter, it is possible to reduce the introduction cost of a system for managing the progress of construction work. Also, by comparing the progress with the display of the construction plan, it is possible to clearly indicate the difference from the construction plan, and to highlight delayed work, work that workers are weak at, and work that they are good at.

[0091] The dashed line in the time chart column of Fig. 3 shows the operation time of the sprayer. In particular, band 71 in the dashed line is the operation time of power-feeding beacon 3b attached to the sprayer, and shows, for example, the time when 400V power was supplied to the sprayer. Bands 72 and 73 in the dashed line are the operation time of acceleration-type beacon 3a attached to a concrete pump (not shown), which is a part of the sprayer.

[0092] The left end of band 71 is the activation start time of power supply type beacon 3b, indicating the start time of power supply to the sprayer. The left end of band 72 is the activation start time of acceleration type beacon 3a, indicating the start time of spraying work by the concrete pump. By comparing bands 71 ​​and 72, when the sprayer starts spraying work, it can be seen that the concrete pump was operated after the power of the sprayer was turned on.

[0093] Conventionally, the start time of spraying work inside a tunnel, which is difficult to monitor remotely, has been set as the start time of power supply to the spraying machine (corresponding to the left end of band 71). However, the start time of the actual spraying work is the start time of spraying work by the concrete pump, and in this embodiment, this can be clearly indicated as the left end of band 72. In other words, the progress management system of this embodiment can visualize the start time of the actual spraying work.

[0094] Moreover, the right end of band 71 is the end time of operation of power-feeding beacon 3b, indicating the end time of power supply to the sprayer. The right end of band 73 is the end time of operation of acceleration-type beacon 3a, indicating the end time of spraying work by the concrete pump. By comparing bands 71 ​​and 73, it can be seen that when the sprayer ends its spraying work, the concrete pump is stopped and then the power to the sprayer is turned off.

[0095] Conventionally, the end time of spraying work inside a tunnel, which is difficult to monitor remotely, has been set as the end time of power supply to the spraying machine (corresponding to the right end of band 71). However, the end time of the actual spraying work is the end time of the spraying work by the concrete pump, and in this embodiment, this can be clearly indicated as the right end of band 73. In other words, the progress management system of this embodiment can visualize the end time of the actual spraying work.

[0096] Moreover, the time from the right end of band 72 to the left end of band 73 is the time when spraying work by the concrete pump is not being performed. This time corresponds to the operating time period of "construction detection (right)" and "construction detection (left)", that is, the time when the shoring is being constructed. By comparing bands 71, 72, and 73, it is clear that the power supply to the sprayer is continuing even when spraying work is not being performed.

[0097] Conventionally, spraying work inside a tunnel, which is difficult to monitor remotely, was determined to be ongoing if power supply was continuing. On the other hand, in this embodiment, the end time of the primary spraying can be clearly indicated as the right end of band 72, and the start time of the secondary spraying can be clearly indicated as the left end of band 73. In other words, the progress management system of this embodiment can visualize the time of shoring construction when spraying work is not actually being performed.

[0098] According to the above description, based on the radio waves from the acceleration type beacon 3a, the working time, start time, and end time of the work performed by the work machine 6 can be determined, and based on the radio waves from the power supply type beacon 3b, the power supply time, start time, and end time when the work machine 6 is powered on to perform work can be determined.

[0099] By comparing the work time, work start time, and work end time with the power supply time, power supply start time, and power supply end time, it is possible to visualize the preparation period from when the power is turned on until the work is started (for example, the difference between the left end of band 71 and the left end of band 72), the cleanup period from when the work is finished until the power is turned off (for example, the difference between the right end of band 71 and the right end of band 73), and the interruption period during which the work (for example, spraying work) was interrupted while the power was left on for some reason (for example, shoring construction, construction trouble) (for example, the difference between the right end of band 72 and the left end of band 73). Therefore, by visualizing the time during which the work machine 6 actually performed work as actual work time and visualizing the preparation period, cleanup period, interruption time, etc. during which work was not performed as non-actual work time, it is possible to improve work progress management.

[0100] The determination unit 12 can continuously determine the current work content throughout the tunnel construction period. As a result, the display device 2 can display a colored band indicating the operating time period for each determined work content at the top of the time chart column in Fig. 3. For convenience of illustration, one cycle of work content is displayed in Fig. 3, but the display device 2 can display a colored band indicating the operating time period for each work content determined by the determination unit 12 for the work content performed in one day (approximately 2.79 cycles). Therefore, for example, the determination unit 12 can calculate the total operating time for one day for each work content. The display control unit 13 provides a display column for the total operating time in the display device 2, and can display the total operating time for one day for each work content.

[0101] (Playback of work content) The camera 5 shown in Fig. 1 photographs the work machine 6 and transmits the photographed image data to the processing device 1. The display device 2, under the control of the display control unit 13 of the processing device 1, can play back and display the work content of the work machine 6 based on the image photographed by the camera 5. This makes it possible to visualize the actual work situation with detailed work content and operation information including the work time displayed in a video. Therefore, the use of the video can improve work progress management.

[0102] The display device 2 can also display an image of the work content to be played back together with the progress time chart of Fig. 3. When the operator of the display device 2 designates a specific date and time, the display device 2 can indicate the designated date and time (for example, with a vertical line) on the progress time chart of Fig. 3 and can also display the work content at the designated date and time on the screen. The display device 2 can also display the playback starting from the designated date and time.

[0103] [process] The progress management process by the progress management system of this embodiment will be described. Fig. 4 is a flowchart of the progress management process. The flowchart in Fig. 4 starts when the analysis unit 11 of the processing device 1 receives data from the receiver 4a closest to the face.

[0104] First, the analysis unit 11 processes the data received from the receiver 4a and analyzes the radio waves received by the receiver 4a (step A1). Next, the analysis unit 11 identifies the beacon 3 that transmitted the radio waves (step A3). The beacon 3 can be identified by acquiring the ID of the beacon 3 contained in the radio waves and referring to the transmitter DB 21. Once the analysis unit 11 identifies the beacon 3, it can identify the work machine 6 to which the beacon 3 was attached by referring to the transmitter DB 21, etc.

[0105] Next, the analysis unit 11 refers to the operation information 16DB and generates or updates the operation information of the identified work machine 6 (step A3). Next, the determination unit 12 executes a work content determination process described below (step A4). Next, the display control unit 13 causes the display device 2 to display a progress time chart (see FIG. 7) based on the generated or updated operation information and the result of the work content determination process (step A5). Thereafter, the progress management process ends.

[0106] (Work content determination process) 5 to 7 are flowcharts of the work content determination process. As shown in Fig. 5, first, the determination unit 12 determines whether or not the radio wave received by the receiver 4a includes the ID of the beacon 3a of the explosives transport vehicle (step B1). If it does (Yes in step B1), the determination unit 12 determines whether or not the radio wave received by the receiver 4a includes the ID of the beacon 3a of the rock drill machine equipped in the drill jumbo or the ID of the beacon 3b of the water pump equipped in the drill jumbo (step B2).

[0107] If it is included (Yes in step B2), the judgment unit 12 regards it as the transportation of explosives during drilling, and provisionally judges that the current work content is drilling (step B2). On the other hand, if it is not included (No in step B2), the judgment unit 12 refers to the "explosives loading" entry in the cycle information 25 and judges whether it is within the duration after the end of drilling (step B5).

[0108] If it is within the duration (Yes in step B5), the determination unit 12 regards it as transportation of explosives after drilling and provisionally determines that the current work content is explosives loading (step B6). On the other hand, if it is not within the duration (No in step B5), the determination unit 12 maintains the previous determination result and determines that the current work content is the determined work content (step B7).

[0109] If the ID of the beacon 3a of the explosives transport vehicle is not included (No in step B1), the determination unit 12 determines whether the radio waves received by the receiver 4a include the ID of the beacon 3a of the rock drill machine equipped in the drill jumbo, or the ID of the beacon 3b of the water pump equipped in the drill jumbo (step B4). If they are included (Yes in step B4), the determination unit 12 determines that the current work content is hole drilling before the explosives are transported, and provisionally determines that the current work content is hole drilling (step B2). On the other hand, if they are not included (No in step B4), the work content determination process ends.

[0110] The determination unit 12 also determines whether the ID of the beacon 3a of the power supply cart is included (step B8). If it is included (Yes in step B8), the determination unit 12 refers to the "blasting" entry in the cycle information 25 and determines whether it is within the duration after the end of the charging (step B9). If it is within the duration (Yes in step B9), the determination unit 12 provisionally determines that the current work content is blasting (step B10). On the other hand, if it is not within the duration (No in step B9), the determination unit 12 maintains the previous determination result and determines that the current work content is the determined work content (step B7). On the other hand, if the ID of the beacon 3a of the power supply cart is not included (No in step B8), the work content determination process ends.

[0111] 6, the determination unit 12 determines whether the ID of the beacon 3a of the wheel loader is included (step B11). If it is included (Yes in step B11), the determination unit 12 provisionally determines that the current work content is shifting (step B12). On the other hand, if it is not included (No in step B11), the work content determination process ends.

[0112] The determination unit 12 also determines whether the ID of the breaker beacon 3a is included (step B13). If it is included (Yes in step B13), the determination unit 12 refers to the "hit taking" entry in the cycle information 25 and determines whether it is within the duration after the end of the shifting out (step B14). If it is within the duration (Yes in step B14), the determination unit 12 provisionally determines that the current work content is hit taking (step B15). On the other hand, if it is not within the duration (No in step B14), the determination unit 12 refers to the "scraping" entry in the cycle information 25 and determines whether it is within the duration after the end of the secondary spraying (step B16).

[0113] If it is within the duration (Yes in step B16), the judgment unit 12 provisionally judges that the current work content is scraping (step B17). On the other hand, if it is not within the duration (No in step B16), the judgment unit 12 maintains the previous judgment result and judges that the current work content is the judged work content (step B7). On the other hand, if the ID of the breaker beacon 3a is not included (No in step B13), the work content judgment process ends.

[0114] The determination unit 12 also determines whether the radio wave received by the receiver 4a includes the ID of the beacon 3a of the concrete pump equipped in the sprayer (step B18). If it does (Yes in step B18), the determination unit 12 refers to the entry for "primary spraying" in the cycle information 25 and determines whether it is within the duration after the end of the lump-out (step B19).

[0115] If it is within the duration (Yes in step B19), the judgment unit 12 provisionally judges that the current work content is primary spraying (step B20). On the other hand, if it is not within the duration (No in step B19), the judgment unit 12 refers to the "secondary spraying" entry in the cycle information 25 and judges whether it is within the duration after the end of the shoring construction (step B21).

[0116] If it is within the duration (Yes in step B21), the determination unit 12 provisionally determines that the current work content is secondary spraying (step B22). On the other hand, if it is not within the duration (No in step B21), the determination unit 12 maintains the previous determination result and determines that the current work content is the determined work content (step B7). On the other hand, if the ID of the concrete pump beacon 3a is not included (No in step B18), the work content determination process ends.

[0117] 7, the determination unit 12 determines whether or not the radio waves received by the receiver 4a include the ID of the magnetic beacon of the man gauge equipped in the spraying machine (step B23). If it does (Yes in step B23), the determination unit 12 provisionally determines that the current work content is shoring construction (step B24). On the other hand, if it does not (No in step B23), the work content determination process ends.

[0118] The determination unit 12 also determines whether the ID of the beacon 3a of the mortar pump equipped in the drill jumbo is included (step B25). If it is included (Yes in step B25), the determination unit 12 provisionally determines that the current work content is RB (step B26). On the other hand, if it is not included (No in step B25), the work content determination process ends.

[0119] Next, the judgment unit 12 makes a final judgment based on the priority order set in the cycle information 25 for at least one of the work contents provisionally judged in steps B3, B6, B10, B12, B15, B17, B22, B24, and B26 and the work contents maintained in step B7 (step B27). One current work content is determined by the final judgment. The display control unit 13 can display the determined work content in a band at the top of the "Time Chart" column of the progress time chart (FIG. 3).

[0120] [effect] According to this embodiment, when the analysis unit 11 analyzes the radio waves received by the receiver 4, the operating work machine 6 can be determined as the analysis result. Furthermore, the determination unit 12 can determine the current work content by referring to the cycle information 25. Therefore, the progress of the construction work can be managed, and the work efficiency of the construction work can be improved by appropriately controlling the work machine 6 according to the progress.

[0121] Furthermore, by setting the previous work conditions and the priority order in the cycle information 25, the current work content can be uniquely identified. Furthermore, by the determination unit 12 continuing to determine the current task content, the display control unit 13 can visualize the task time for each task content, thereby making it easy to manage the progress of each task content. Furthermore, the display control unit 13 can display the work time divided into actual work time and non-actual work time, thereby making it possible to clearly show the contribution of the work machine 6. This makes it possible to easily manage the progress of each work content.

[0122] [others] (a): The progress management process of this embodiment is capable of determining the content of ongoing work in real time and displaying it on the screen. However, for example, the determination unit 12 can obtain operation information for a predetermined period of the past from the operation information DB 23 and determine the work content at each point in time based on the obtained operation information. Furthermore, the display control unit 13 can display the determination result of the determination unit 12 on the screen. (b) The work content may be determined by analyzing radio waves from an acceleration-type beacon 3a attached to the work machine 6 and analyzing the intensity and waveform of the vibration of the work machine 6 to determine the operating status of the work machine 6. For example, if a wheel loader performing littering is idling, vibrations different from those when littering can be detected, making it possible to determine in detail whether the work content is littering or not.

[0123] (c): Examples of applications of work progress management using beacons include mapping of equipment and materials, water level detection (submersion detection) of monitored objects, electrical machinery operation management, door opening / closing management (including construction machinery doors, toilet doors, etc.), seating management (including construction machinery seats, chairs in waiting areas, etc.), and remaining material management (including cement bags on pallets, etc.). (d) The visualization of work progress using a progress time chart according to this embodiment can also be applied to construction work other than tunnel construction. (e) The determination unit 12 can obtain the operating time of the work machine 6, and can therefore calculate the amount of CO2 emissions from the work machine 6 based on the fuel efficiency of the work machine 6 (known).

[0124] (f): In this embodiment, the charge is judged based on the movement of the explosives transport vehicle. However, for example, if the drill jumbo is equipped with an explosives loading arm, an automatic explosives loading device arranged on the explosives loading arm may be used. An acceleration type beacon 3a is attached to the explosives loading device, and the charge can be judged based on the analysis result of the radio wave from the beacon 3a. (g): In this embodiment, the blasting was judged based on the operating status of the power supply dolly. However, for example, a blasting operation device to which power is supplied by the power supply dolly may be used. At least one of an acceleration type beacon 3a and a power supply type beacon 3b may be attached to the blasting operation device, and the blasting can be judged based on the analysis results of the radio waves from the beacons 3a and 3b.

[0125] (h): It is also possible to realize a technology that appropriately combines the various technologies described in this embodiment. (i): The software described in this embodiment can be realized as hardware, and the hardware can be realized as software. (j) In addition, the components of the present invention can be modified as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
