In addition, the device 10 may be in the form of cloud computing or edge computing, for example, in which at least one of the aforementioned parts is on a server and the other aforementioned parts are on a terminal.

[0015] Figure 2 illustrates a block diagram of the hardware configuration of the device 10. The device 10 includes, for example, a central processing unit (CPU, GPU, etc.) 101, memory 102, bus 103, storage device 104, input device 105, output device 106, communication device 107, etc. Each part of the device 10 is interconnected via the bus 103 through its respective interface (I / F).

[0022] Next, an example of a state determination method according to this disclosure will be described below with reference to Figure 3. The state determination method of this embodiment is carried out as follows, for example, using the device 10 shown in Figure 1 or Figure 2. Note that the state determination method of this embodiment is not limited to the use of the device 10 shown in Figure 1 or Figure 2.

[0023] The acquisition unit 11 acquires vibration detection information and radio wave detection information from the tunnel construction machinery (S11, acquisition process). The vibration detection information is information relating to the detection of vibrations in the machinery by the machinery. The radio wave detection information is information relating to the detection of directional radio waves transmitted from the transmitting device by the machinery.

[0024] The operation determination unit 12 determines whether or not the machine is operating based on the vibration detection information (S12, operation determination step).

[0025] The area determination unit 13 determines the area where the machine is located based on the radio wave detection information (S13, area determination step).

[0026] The state determination unit 14 determines the state of the machine based on the determination result by the operation determination unit 12 and the determination result by the area determination unit 13 (S14, state determination step).

[0027] The output unit 15 outputs the determination result from the state determination unit 14 as state determination information (S15, output step).

[0028] The tunnel construction machinery is, for example, machinery used in tunnel construction. The types of tunnels include, for example, mountain tunnels, urban tunnels, and underwater tunnels. The machinery includes, for example, construction machinery. The construction machinery includes, for example, drill jumbos, breakers, free-section excavators (e.g., boom headers®), dump trucks, wheel loaders, and concrete sprayers. The machinery includes, for example, vibration detection means and radio wave detection means. The machinery may also include, for example, a detection information output device described later.

[0029] The vibration of the machine may be detected, for example, by vibration detection means provided in the machine. The vibration detection means is, for example, a detection means capable of detecting vibrations to be detected. Examples of the vibration detection means include acceleration detection means. The vibration detection means may be provided in the machine in a detachable state, in a fixed state, or built into the machine. The position in which the vibration detection means is provided may be, for example, a position in the machine where the vibration can be detected. The position in which the vibration detection means is provided may be, for example, a different position from the aforementioned radio wave detection means, or the same position as the aforementioned radio wave detection means. The number of vibration detection means may be, for example, one or two or more per machine. The machine may be equipped with, for example, a detection information output device including the vibration detection means, or the vibration detection means and the detection information output device may be provided separately. The detection information output device may, for example, include the aforementioned radio wave detection means in addition to the vibration detection means if the machine is equipped with a detection information output device that includes the vibration detection means, and examples of such detection information output devices include IET10MO (SJI Co., Ltd.).

[0030] The vibration detection means may, for example, output information regarding the detection of vibration to the detection information output device when the vibration detection means detects vibration, and the detection information output device may, for example, acquire the outputted information regarding the detection of vibration from the vibration detection means. The detection information output device may, for example, generate vibration detection information based on the vibration detection by the vibration detection means and output the generated vibration detection information to the state determination device according to this disclosure. Alternatively, the detection information output device may, for example, output the information regarding the detection of vibration itself as vibration detection information to the state determination device according to this disclosure. The acquisition unit 11 may, for example, acquire the vibration detection information from a detection information output device provided by a tunnel construction machine. The detection information output device may, for example, output the vibration detection information to the state determination device according to this disclosure via a wired or wireless communication network. Examples of the communication network include Low Power Wide Area (LPWA). Examples of LPWA include Sigfox®.

[0031] As described above, the vibration detection information is, for example, information relating to the detection of vibrations in the machine by the machine. The vibration detection information includes, for example, vibration detection presence / absence information relating to whether or not the vibration was detected by the vibration detection means, vibration degree information relating to the degree of vibration detected by the vibration detection means, and vibration detection time information relating to the time when the vibration detection means detected the vibration. The vibration degree information includes, for example, information relating to the degree of acceleration, information relating to the degree of velocity, and information relating to the degree of displacement. The acquisition unit 11 may acquire the vibration detection information in real-time processing format or in batch processing format.

[0032] The vibration detection information may include, for example, other information. This other information may include, for example, information that can identify the machine, information that can identify the vibration detection means, and information that can identify the detection information output device. The state determination device according to this disclosure may, for example, identify the machine that is the source of the vibration detection information based on at least one of these identifiable pieces of information. In this case, the state determination device according to this disclosure may perform the identification based on, for example, a database that associates at least one of these identifiable pieces of information with each of the machines.

[0033] The operation determination unit 12 may determine, for example, that the machine is operating if the vibration detection information satisfies predetermined conditions. The predetermined conditions for the vibration detection information may be, for example, whether or not the vibration is detected by the vibration detection means. In this case, the operation determination unit 12 may determine that the machine is operating if, for example, the vibration detection means detects the vibration. On the other hand, the operation determination unit 12 may determine that the machine is not operating if, for example, the vibration detection means does not detect the vibration. If the vibration detection information includes information on whether or not the vibration is detected, the operation determination unit 12 may determine whether or not the vibration detection means has detected the vibration based on the information on whether or not the vibration is detected. Note that the operation of the machine can be rephrased as, for example, the operation of the engine provided by the machine. The determination of whether or not the machine is operating can be rephrased as, for example, the determination of whether or not the engine provided by the machine is operating.

[0034] Furthermore, the predetermined conditions for the vibration detection information may be, for example, the degree of vibration detected by the vibration detection means. In this case, the operation determination unit 12 may determine that the machine is operating if, for example, the degree of vibration detected by the vibration detection means is equal to or greater than a predetermined threshold, or if the degree of vibration detected by the vibration detection means exceeds a predetermined threshold. On the other hand, the operation determination unit 12 may determine that the machine is not operating if, for example, the degree of vibration detected by the vibration detection means is less than or equal to a predetermined threshold, or if the degree of vibration detected by the vibration detection means is less than a predetermined threshold. Thus, if the vibration detection information includes the degree of vibration detection information, the operation determination unit 12 may perform a determination process based on the degree of vibration detected by the vibration detection means and a predetermined threshold. The predetermined threshold may be set appropriately, for example, according to the operating environment of the vibration detection means.

[0035] The transmitting device is a device that emits directional radio waves. The transmitting device may be positioned as a reference to divide an area in tunnel construction into two areas. That is, the area in tunnel construction may be divided, for example, with the transmitting device as a reference, into an area in a direction along the direction of the radio waves and an area in a direction opposite to the direction of the radio waves. The purpose of the divided areas may be set appropriately, for example, according to the tunnel construction. Examples of the purposes of the divided areas include a work area for carrying out work and a non-work area where no work is carried out. The transmitting device may be positioned as a reference to divide an area in tunnel construction into a work area and a non-work area. The area in tunnel construction may be divided, for example, with the transmitting device as a reference, into a work area in a direction along the direction of the radio waves and a non-work area in a direction opposite to the direction of the radio waves.

[0036] The transmitting device may be, for example, a device that emits radio waves detectable by the radio wave detection means within the tunnel. The transmitting device may be, for example, a beacon. The beacon may be, for example, a Bluetooth Low Energy (BLE) beacon. The transmitting device may be positioned, for example, opposite the work area. The transmitting device may be positioned, for example, opposite the tunnel face area, opposite the tunnel entrance area, etc. The tunnel face area may be, for example, an area corresponding to the excavation surface of the tunnel. The tunnel entrance area may be, for example, an area corresponding to the entrance of the tunnel. The position of the transmitting device may be changed as appropriate, for example, depending on the effective range of the radio waves. The transmitting device may be positioned, for example, outside the tunnel or inside the tunnel. The transmitting device may be positioned, for example, on the ground inside the tunnel, on the wall inside the tunnel, or on the ceiling inside the tunnel. The number of transmitting devices may be, for example, one or two or more. The transmitting device may emit the radio waves at predetermined intervals or at any arbitrary timing.

[0037] The radio waves are, for example, directional radio waves. The directionality of the radio waves may be, for example, directionality toward the work area. The directionality of the radio waves may be, for example, directionality toward the tunnel face area, directionality toward the tunnel entrance area, etc. The standard for the radio waves may be, for example, Bluetooth®. The format of the Bluetooth may be, for example, Bluetooth Low Energy (BLE). The radio waves may include, for example, information that can identify the transmitting device.

[0038] The radio waves may be detected, for example, by radio wave detection means provided in the machine. The radio wave detection means may be appropriately selected from known detection means, for example, depending on the type of radio wave to be detected. The radio wave detection means may be, for example, a detection means capable of detecting Bluetooth if the radio wave standard is Bluetooth. The radio wave detection means may be, for example, provided in the machine in a detachable state, provided in a fixed state, or provided in the machine in a built-in state. The position in which the radio wave detection means is provided may be, for example, a position in the machine where the radio waves can be detected. The position in which the radio wave detection means is provided may be, for example, a different position from the vibration detection means, or the same position as the vibration detection means. The number of radio wave detection means may be, for example, one or two or more per machine. The machine may, for example, be equipped with a detection information output device including the radio wave detection means, or it may be equipped with the radio wave detection means and the detection information output device separately. The detection information output device may, for example, include the vibration detection means in addition to the radio wave detection means if the machine is equipped with a detection information output device that includes the radio wave detection means, and an example of such a detection information output device is the IET10MO.

[0039] The radio wave detection means may, for example, output information relating to the detection of radio waves to the detection information output device when the radio wave detection means detects radio waves, and the detection information output device may, for example, acquire the outputted information relating to the detection of radio waves from the radio wave detection means. The detection information output device may, for example, generate radio wave detection information based on the detection of radio waves by the radio wave detection means and output the generated radio wave detection information to the state determination device according to this disclosure. The detection information output device may also, for example, output the information relating to the detection of radio waves itself as radio wave detection information to the state determination device according to this disclosure. The acquisition unit 11 may, for example, acquire the radio wave detection information from a detection information output device provided by a tunnel construction machine. The detection information output device may, for example, output the radio wave detection information to the state determination device according to this disclosure via a wired or wireless communication network. Examples of the communication network include LPWA. Examples of LPWA include Sigfox.

[0040] As described above, the radio wave detection information is information relating to the detection by the machine of directional radio waves transmitted from the transmitting device. Examples of the radio wave detection information include radio wave detection presence / absence information relating to whether or not the radio waves were detected by the radio wave detection means, radio wave intensity information relating to the intensity of the radio waves detected by the radio wave detection means, and radio wave detection time information relating to the time when the radio wave detection means detected the radio waves. Examples of the radio wave intensity information include information relating to the received signal strength (RSSI). The acquisition unit 11 may acquire the radio wave detection information in real-time processing format or in batch processing format.

[0041] The radio wave detection information may include, for example, other information. This other information may include, for example, information that can identify the transmitting device, information that can identify the machine, information that can identify the radio wave detection means, and information that can identify the detection information output device. The state determination device according to this disclosure may, for example, identify the machine that is the source of the radio wave detection information based on at least one of these identifiable pieces of information. In this case, the state determination device according to this disclosure may perform the identification based on, for example, a database that associates at least one of these identifiable pieces of information with each of the machines.

[0042] The area determination unit 13 may, for example, determine that the machine is located in the work area if the radio wave detection information satisfies predetermined conditions. The predetermined conditions for the radio wave detection information may, for example, be whether or not the radio waves are detected by the radio wave detection means. In this case, the area determination unit 13 may, for example, determine that the machine is located in the work area if the radio wave detection means detects the radio waves. On the other hand, the area determination unit 13 may, for example, determine that the machine is not located in the work area if the radio wave detection means does not detect the radio waves. The area determination unit 13 may, for example, determine that the machine is located in a non-work area if the radio wave detection means does not detect the radio waves. If the radio wave detection information includes radio wave detection presence / absence information, the area determination unit 13 may, for example, determine whether or not the radio wave detection means detected the radio waves based on the radio wave detection presence / absence information.

[0043] Furthermore, the predetermined conditions for the radio wave detection information may be, for example, the intensity of the radio waves detected by the radio wave detection means. In this case, the area determination unit 13 may determine, for example, that the machine is located in the work area if the intensity of the radio waves detected by the radio wave detection means is equal to or greater than a predetermined threshold, or if the intensity of the radio waves detected by the radio wave detection means exceeds a predetermined threshold. On the other hand, the area determination unit 13 may determine, for example, that the machine is not located in the work area if the intensity of the radio waves detected by the radio wave detection means is less than or equal to a predetermined threshold, or if the intensity of the radio waves detected by the radio wave detection means is less than a predetermined threshold. The area determination unit 13 may also determine, for example, that the machine is located in a non-work area if the intensity of the radio waves detected by the radio wave detection means is less than or equal to a predetermined threshold, or if the intensity of the radio waves detected by the radio wave detection means is less than a predetermined threshold. Thus, if the radio wave detection information includes the intensity of the radio wave detection, the area determination unit 13 may, for example, perform a determination process based on the intensity of the radio waves detected by the radio wave detection means and a predetermined threshold. The predetermined threshold may be set appropriately, for example, depending on the operating environment of the radio wave detection means.

[0044] The area determination unit 13 may, for example, execute area determination processing based on the radio wave detection information only when the operation determination unit 12 determines that the machine is in operation. Specifically, the area determination unit 13 may, for example, determine the area where the machine is located based on the radio wave detection information when the operation determination unit 12 determines that the machine is in operation. On the other hand, the area determination unit 13 does not have to execute area determination processing based on the radio wave detection information when the operation determination unit 12 determines that the machine is not in operation. In this case, the state determination unit 14 may, for example, determine the state of the machine based only on the determination result by the operation determination unit 12. Specifically, the state determination unit 14 may, for example, determine that the machine is in a non-working state when the operation determination unit 12 determines that the machine is not in operation and the area determination processing is not executed by the area determination unit 13. Furthermore, the state determination unit 14 may determine that the machine is in a stopped state if, for example, the operation determination unit 12 determines that the machine is not operating, and the area determination process is not executed by the area determination unit 13.

[0045] The state determination unit 14 may determine, for example, that the machine is in a working state if the determination result by the operation determination unit 12 satisfies predetermined conditions and the determination result by the area determination unit 13 satisfies predetermined conditions. The predetermined conditions for the determination result by the operation determination unit 12 may be, for example, whether or not the machine is in operation. The predetermined conditions for the determination result by the area determination unit 13 may be, for example, whether or not the machine is located in a work area.

[0046] The state determination unit 14 determines, for example, that the machine is in operation if the operation determination unit 12 determines that the machine is operating and the area determination unit 13 determines that the machine is located in the work area (S14A-1, state determination step).

[0047] On the other hand, the state determination unit 14 determines that the machine is in a non-working state if, for example, the operation determination unit 12 determines that the machine is in operation and the area determination unit 13 determines that the machine is not located in the work area (S14A-2, state determination step). The state determination unit 14 may also determine that the machine is in a standby state if, for example, the operation determination unit 12 determines that the machine is in operation and the area determination unit 13 determines that the machine is not located in the work area.

[0048] Furthermore, the state determination unit 14 may determine that the machine is in a non-operating state if, for example, the operation determination unit 12 determines that the machine is not operating and the area determination unit 13 determines that the machine is located in the work area (S14B-1, state determination step). In addition, the state determination unit 14 may determine that the machine is in a stopped state if, for example, the operation determination unit 12 determines that the machine is not operating and the area determination unit 13 determines that the machine is located in the work area.

[0049] On the other hand, the state determination unit 14 may determine that the machine is in a non-working state if, for example, the operation determination unit 12 determines that the machine is not in operation and the area determination unit 13 determines that the machine is not located in the work area (S14B-2, state determination step). The state determination unit 14 may also determine that the machine is in a stopped state if, for example, the operation determination unit 12 determines that the machine is not in operation and the area determination unit 13 determines that the machine is not located in the work area.

[0050] The aforementioned working state is, for example, the state in which the machine is performing work. The aforementioned work is, for example, work performed using the machine in tunnel construction. Examples of such work include excavation work, excavation work, concrete spraying work, support structure installation work, rock bolt installation work, forepoling or forepiling work, etc. The aforementioned non-working state is, for example, the state in which the machine is not performing the aforementioned work. The aforementioned non-working state includes, for example, at least one of the standby state and the stopped state. The standby state is, for example, the state in which the machine is on standby for the aforementioned work. The stopped state is, for example, the state in which the machine has stopped after being released from the aforementioned work.

[0051] The output unit 15 may, for example, output the state determination information to a work management support device described later. The output unit 15 may, for example, output the state determination information to an output device 106 provided by the state determination device according to this disclosure, or to another output device provided by a device other than the state determination device according to this disclosure. The output unit 15 may, for example, output the state determination information to a memory 102 or storage device 104 provided by the state determination device according to this disclosure, or to another memory or storage device provided by a device other than the state determination device according to this disclosure. In this case, the output unit 15 may, for example, store the outputted state determination information in the memory or storage device of these devices.

[0052] Based on the above, the status determination device according to this disclosure acquires vibration detection information and radio wave detection information from tunnel construction machinery using an acquisition unit, determines whether or not the machinery is operating based on the vibration detection information using an operation determination unit, determines the area in which the machinery is located based on the radio wave detection information using an area determination unit, determines the status of the machinery based on the determination result from the operation determination unit and the determination result from the area determination unit using a status determination unit, and outputs the determination result from the status determination unit as status determination information using an output unit. For this reason, according to this disclosure, the status of tunnel construction machinery can be determined more accurately.

[0053] Tunnel construction machinery can be in various states, such as working or standby, under operating conditions. Specifically, tunnel construction machinery may be operating because it is actually performing work, or it may be operating while idling and on standby. Therefore, it may not have been possible to determine whether tunnel construction machinery is in a working state or not based solely on its operating state. Furthermore, it may not have been possible to determine whether tunnel construction machinery is in a working state or standby state based solely on its operating state. In contrast, according to this disclosure, under operating conditions, it is possible to determine whether tunnel construction machinery is in a working state or not based on the area in which it is located. Furthermore, according to this disclosure, under operating conditions, it is possible to determine whether tunnel construction machinery is in a working state or standby state based on the area in which it is located. Therefore, according to this disclosure, the state of tunnel construction machinery can be determined more accurately.

[0054] Furthermore, this disclosure determines, for example, the status of tunnel construction machinery based on area determination results and operation determination results. Therefore, according to this disclosure, for example, the status of tunnel construction machinery can be determined more accurately compared to determination based solely on operation determination results. Also, according to this disclosure, for example, the start and end of work of tunnel construction machinery can be determined more accurately compared to determination based solely on operation determination results.

[0058] [Embodiment 3] An example of the state determination system of the present disclosure will be described with reference to Figure 4. As shown in Figure 4, the state determination system 100 of the present disclosure includes a transmitting device 40, a detection information output device 50, and a state determination device 10.

The hardware configuration of the state determination device 10 is such that, in the hardware configuration of the state determination device 10 in Figure 2, the central processing unit 201 includes a configuration similar to that of the state determination device 10 in Figure 4.

[0062] An example of processing using the state determination method of this disclosure will be explained with reference to Figure 5. Figure 5 is a flowchart showing an example of each step of the state determination method of this disclosure. The state determination method of this disclosure (hereinafter also referred to as "the method of this disclosure") can be implemented, for example, using the state determination device 10 shown in Figure 1 or the hardware configuration shown in Figure 2 in which the central processing unit 101 includes the state determination device 10 instead of the state determination device 10. Figure 5 shows an example of processing using the method utilizing the transmitter 40 (S41). Figure 5 shows an example of processing using the method utilizing the detection information output device 50 (S51-S54). Figure 5 shows an example of processing using the method utilizing the state determination device 10 (S11A and S12-S15). Note that the method of this disclosure is not limited to, for example, the method utilizing the device 10. The state determination system of this disclosure can, for example, utilize the descriptions of the method and the device of this disclosure.

[0063] The transmitting unit 41 of the transmitting device 40 transmits, for example, radio waves that have directionality toward the tunnel face area (S41, transmission process). The transmitting device is, for example, a device positioned opposite the tunnel face area in tunnel construction.

[0064] The vibration detection means 51 provided in the detection information output device 50 detects vibrations of the machine, for example (S51, vibration detection step).

[0065] The radio wave detection means 52 provided in the detection information output device 50 detects the radio waves, for example (S52, radio wave detection step).

[0066] The detection information generation unit 53 of the detection information output device 50 generates vibration detection information based on the detection of vibration, and generates radio wave detection information based on the detection of radio waves (S53, detection information generation step). The vibration detection information is, for example, information relating to the detection of vibration of the machine by the vibration detection means. The radio wave detection information is, for example, information relating to the detection of radio waves by the radio wave detection means.

[0067] The detection information output unit 54 of the detection information output device 50 outputs, for example, the vibration detection information and the radio wave detection information to the state determination device 10 (S54, detection information output step).

In this case, the operation determination unit 12, area determination unit 13, state determination unit 14, and output unit 15 of the state determination device 10 may perform, for example, operation determination processing, area determination processing, state determination processing, and output processing based on the vibration detection information and the radio wave detection information (S12~S15). Each of the above processes can be described by referring to, for example, the description in Embodiment 1.

[0070] The state determination program of this disclosure (hereinafter also referred to as the program of this disclosure) is a program that is implemented by, for example, replacing each "step" in the method of this disclosure with a "procedure". Specifically, the program of this disclosure includes a transmission procedure provided by a transmission device which transmits radio waves having directionality toward the working face area, a vibration detection means provided by a detection information output device which detects vibrations of the machine, a radio wave detection means provided by a detection information output device which detects the radio waves, a generation procedure provided by a detection information output device which generates vibration detection information based on the detection of vibrations and generates radio wave detection information based on the detection of radio waves, a detection information output procedure provided by a detection information output device which outputs the vibration detection information and the radio wave detection information to a state determination device, and an acquisition procedure provided by a state determination device which acquires the vibration detection information and the radio wave detection information from the detection information output device. The program of this disclosure can be implemented, for example, using a transmission device 40, a detection information output device 50, and a state determination device 10 included in the state determination system 100 shown in Figure 4. Furthermore, the program of this disclosure can be implemented using, for example, the state determination device 10 shown in Figure 4 or the hardware configuration shown in Figure 2. However, the program of this disclosure is not limited to, for example, a program utilizing the device 10. The program of this disclosure can, for example, utilize the descriptions of the method and apparatus of this disclosure.

[0071] As described above, according to the state determination system of this disclosure, the transmitting unit of the transmitting device transmits radio waves having directionality toward the tunnel face area, the vibration detection means of the detection information output device detects vibrations of the machine, the radio wave detection means of the detection information output device detects the radio waves, the detection information generation unit of the detection information output device generates vibration detection information based on the detection of vibrations and generates radio wave detection information based on the detection of radio waves, the detection information output unit of the detection information output device outputs the vibration detection information and the radio wave detection information to the state determination device, and the acquisition unit of the state determination device can acquire the vibration detection information and the radio wave detection information from the detection information output device. For this reason, according to this disclosure, the state of machinery for tunnel construction can be determined more accurately.

[0072] [Embodiment 4] An example of how the status determination system described in this disclosure can be used is explained below with reference to Figure 6. However, this disclosure is not limited to the following explanation.

[0073] First, the status determination device acquires vibration detection information and radio wave detection information from each construction machine, for example. Specifically, the drill jumbo, which is a construction machine, is, for example, performing excavation work in the tunnel face area of ​​a tunnel construction project. The drill jumbo is, for example, in a state where its body is vibrating because it is operating for excavation work. On the other hand, the dump truck, which is a construction machine, is, for example, waiting in the tunnel entrance area for excavation work to remove the excavated material. The dump truck is, for example, idling for excavation work to remove the excavated material, so its body is vibrating. The area in the tunnel construction project is divided into, for example, a work area where work is performed and a non-work area where no work is performed. The BLE beacon is positioned, for example, as a criterion for dividing the area in the tunnel construction project into the work area and the non-work area. The BLE beacon is positioned, for example, facing the tunnel face area. The drill jumbo and the dump truck are each equipped with, for example, an IET10MO as a detection information output device including vibration detection means and radio wave detection means. Under these conditions, the BLE beacon transmits, for example, radio waves that are directional toward the drill face area. The IET10MO on the drill jumbo can detect the radio waves by the radio wave detection means because, for example, the drill jumbo is positioned in a direction aligned with the directionality of the radio waves. On the other hand, the IET10MO on the dump truck cannot detect the radio waves by the radio wave detection means because, for example, the dump truck is positioned in a direction contrary to the directionality of the radio waves. In contrast, the IET10MO on each construction machine can detect the vibrations of each construction machine by the vibration detection means, for example, because the drill jumbo and the dump truck are in a state of vibration. The IET10MO on each construction machine generates vibration detection information based on the detection of vibrations and generates radio wave detection information based on the detection of radio waves. The IET10MO on each construction machine outputs the vibration detection information and the radio wave detection information to a state determination device, for example.The state determination device acquires, for example, the vibration detection information and the radio wave detection information from the IET10MO.

[0074] Next, the status determination device outputs status determination information based, for example, on the vibration detection information and the radio wave detection information. Specifically, the user uses the status determination device to ascertain the status of each construction machine performing tunnel construction work, for example, in an office outside the tunnel. The status determination device determines, for example, whether each construction machine is in operation based on the vibration detection information. Each construction machine is determined to be in operation because, for example, the vibration has been detected by the vibration detection means. After it is determined that each construction machine is in operation, the status determination device determines, for example, the area in which each construction machine is located based on the radio wave detection information. The drill jumbo is determined to be located in the work area because, for example, the radio waves have been detected by the radio wave detection means. On the other hand, the dump truck is determined not to be located in the work area because, for example, the radio waves have not been detected by the radio wave detection means. The status determination device determines the status of each construction machine based on the respective determination results. The drill jumbo is determined to be in working condition, for example, because it is determined that the drill jumbo is operational and that it is located in the work area. On the other hand, the dump truck is determined to be in standby condition, for example, because it is determined that the dump truck is operational and that the drill jumbo is not located in the work area. In this way, the state determination device can determine, for example, whether the state of each construction machine is in working condition or standby condition, under the condition that each construction machine is operational. The state determination device outputs the determination result for the state of each construction machine as state determination information to its display unit. The user can understand the state of each construction machine in tunnel construction by, for example, viewing the state determination information output to the display unit.

[0075] According to this disclosure, the condition of tunnel construction machinery can be determined more accurately. Furthermore, according to this disclosure, the effects described in Embodiments 1-3, for example, can be achieved.

[0076] [Embodiment 5] Figure 7 is a block diagram showing an example of the configuration of the work management support device according to this disclosure (hereinafter also referred to as "the device 20A"). As shown in Figure 7, the device 20A includes a state determination information acquisition unit 21, a work information generation unit 22, and a status analysis unit 23. In addition, although not shown, the device 20A may also include, for example, an input unit, an information acquisition unit, other output units, an analysis result output unit, a display unit, and / or a storage unit.

[0077] The device 20A may be, for example, a single device including the aforementioned parts, or it may be a device in which the aforementioned parts can be connected via a communication network. Furthermore, the device 20A can be connected to an external device described later via the communication network. The communication network is not particularly limited and can use a known network, for example, it may be wired or wireless. Examples of the communication network include the Internet, WWW (World Wide Web), telephone lines, LAN (Local Area Network), SAN (Storage Area Network), DTN (Delay Tolerant Networking), LPWA (Low Power Wide Area), L5G (Local 5G), etc. Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), Local 5G, LPWA, etc. The wireless communication may be in the form of direct communication between devices (Ad Hoc communication), infrastructure communication, indirect communication via an access point, etc. The device 20A may be incorporated into a system server, for example. Furthermore, the device 20A may be, for example, a personal computer (PC, e.g., desktop or notebook), smartphone, tablet terminal, etc., on which the program of this disclosure is installed. In addition, the device 20A may be in a form such as cloud computing or edge computing, where, for example, at least one of the aforementioned parts is on a server and the other aforementioned parts are on a terminal.

[0078] Figure 8 shows an example block diagram of the hardware configuration of the device 20A. The device 20A includes, for example, a central processing unit (CPU, GPU, etc.) 201, memory 202, bus 203, storage device 204, input device 205, output device 206, communication device 207, etc. Each part of the device 20A is interconnected via the bus 203 through its respective interface (I / F).

[0079] The central processing unit 201 operates in cooperation with other components via controllers (system controller, I / O controller, etc.) and is responsible for the overall control of the device 20A. In the device 20A, the central processing unit 201 executes, for example, the program disclosed herein or other programs, and also reads and writes various types of information. Specifically, for example, the central processing unit 201 functions as a state determination information acquisition unit 21, a work information generation unit 22, and a status analysis unit 23. If the device 20A includes the aforementioned other output units, the central processing unit 201 may function as one of those other output units. The device 20A may also include other arithmetic units such as a CPU, GPU (Graphics Processing Unit), APU (Accelerated Processing Unit), or a combination of a CPU and these.

[0080] Bus 203 can also be connected to external devices, for example. Examples of such external devices include a user terminal, an external storage device (such as an external database), a printer, an external input device, an external display device, and an external imaging device. The device 20A can be connected to an external network (the aforementioned communication network) via a communication device 207 connected to bus 203, and can also be connected to other devices via the external network.

[0081] Memory 202 may be, for example, main memory. When the central processing unit 201 performs processing, memory 202 reads various operational programs, such as the program of this disclosure, stored in the storage device 204 (described later), and the central processing unit 201 receives data from memory 202 and executes the program. The main memory may be, for example, RAM (random access memory). Alternatively, memory 202 may be, for example, ROM (read-only memory).

[0082] The storage device 204 is also called an auxiliary storage device, for example, in relation to the main memory (primary memory). As described above, the storage device 204 stores an operating program including the program of this disclosure. The storage device 204 may be, for example, a combination of a recording medium and a drive for reading from and writing to the recording medium. The recording medium is not particularly limited and may be internal or external, for example, an HD (hard disk), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, memory card, etc. The storage device 204 may be, for example, a hard disk drive (HDD) in which the recording medium and the drive are integrated, or a solid state drive (SSD). If the device 20A includes the storage unit, for example, the storage device 204 functions as the storage unit. The storage unit can store, for example, state determination information, plan information, work information, analysis result information, work type information, and work performance information, etc., which will be described later.

[0083] In this device 20A, the memory 202 and storage device 204 can also store various types of information, such as log information, information obtained from an external database (not shown) or external devices, information generated by this device 20A, and information used by this device 20A when executing processing. In this case, the memory 202 and storage device 204 may store, for example, the aforementioned planning information. At least some of the information may be stored on an external server other than the memory 202 and storage device 204, or it may be stored in a distributed manner across multiple terminals using blockchain technology or the like.

[0084] The device 20A further includes, for example, an input device 205 and an output device 206. The input device 205 may include, for example, a pointing device such as a touch panel, trackpad, or mouse; a keyboard; imaging means such as a camera or scanner; a card reader such as an IC card reader or magnetic card reader; an audio input means such as a microphone; and so on. The output device 206 may include, for example, a display device such as an LED display or liquid crystal display; an audio output device such as a speaker; a printer; and so on. In this embodiment 5, the input device 205 and the output device 206 are configured separately, but the input device 205 and the output device 206 may be configured as an integrated unit, such as a touch panel display.

[0085] Next, an example of the work management support method according to this disclosure will be described below with reference to Figure 9. The work management support method of this embodiment is implemented, for example, using the device 20A shown in Figure 7 or Figure 8, as follows. Note that the work management support method of this embodiment is not limited to the use of the device 20A shown in Figure 7 or Figure 8.

[0086] First, the state determination information acquisition unit 21 acquires the state determination information from, for example, a state determination device (S21, state determination information acquisition step). The state determination device may be, for example, the state determination device described in any of the embodiments 1 to 4.

[0087] The work information generation unit 22 generates work information based on the status determination information, for example (S22, work information generation step). The work information includes, for example, information regarding the work performance of machinery used in tunnel construction.

[0088] The work information generation unit 22 may generate the work information by, for example, setting at least one of the machine's start time, stop time, and work time as the machine's work record. Specifically, the work information generation unit 22 may, for example, determine that the machine is operating if the state determination information indicates that the machine is in a working state. In this determination, the work information generation unit 22 may, for example, set the time corresponding to the transition when the machine transitions from a non-working state to a working state as the machine's start time. The work information generation unit 22 may also, for example, determine that the machine is stopped if the state determination information indicates that the machine is in a non-working state. In this determination, the work information generation unit 22 may, for example, set the time corresponding to the transition when the machine transitions from a working state to a non-working state as the machine's stop time. The work information generation unit 22 may also, for example, set the time from the machine's start time to the machine's stop time as the machine's work time. The aforementioned work information may, for example, be information associated with information that can identify the machine.

[0089] The situation analysis unit 23 analyzes the status of the tunnel construction based on, for example, the planning information and the work information for the corresponding work unit, and generates analysis result information (S23, situation analysis process).

[0090] Tunnel construction is managed by dividing it into work units called cycle times, for example, to track the progress of the work. Therefore, a construction plan is created for each of these work units. The construction plan specifies the details of the work, for example, assigning a support number and specifying excavation 150 minutes, spoil removal 120 minutes, primary shotcrete 15 minutes, support installation 15 minutes, secondary shotcrete 60 minutes, rock bolting 15 minutes, and filled fore boring 15 minutes. Therefore, the planning information includes, for example, information regarding the construction plan for each work unit of the tunnel construction. Furthermore, the planning information includes, for example, a detailed breakdown as described above. Note that the above examples are just examples, and the content of the planning information is not limited to these. Also, since tunnel construction involves repeating similar tasks, the work procedures may be standardized depending on the work content. Therefore, the work content in the construction plan is standardized according to the type of work, for example. In other words, the type of work defines the type of work content according to the content of the work for each of the work units. As a result, the planning information is planned, for example, by specifying a support pattern (type of work). The work information includes, for example, information on the work performance of machinery used in tunnel construction. In tunnel construction, for example, specific machinery is used. Therefore, the work status can be understood, for example, by understanding the work status of the machinery. The situation analysis unit 23 analyzes the work status by, for example, comparing the work information related to the construction plan, which is defined in detail as described above, with the work status of the machinery used in the construction.

[0091] The aforementioned planning information is, for example, information stored in a database for managing the progress of construction work. For example, the status analysis unit 23 refers to the information in the database and uses it to analyze the status of construction work. The method of using the planning information is not limited to this, and for example, information stored in the storage unit of the device 20A may also be used. Furthermore, the method of use may be any method that can be used to analyze the status in the device 20A, such as inputting information into the device or importing from an external device. For example, the information acquisition unit of the device 20A may acquire the planning information. The information acquisition unit may acquire the planning information by, for example, inputting the planning information via the input unit of the device. Also, as mentioned above, construction plans may be categorized according to the content of each work unit. For example, the information acquisition unit may acquire the planning information by having a construction supervisor select and register a work type such as a support pattern according to the content of the work unit. Therefore, even when the information acquisition unit of the device 20A acquires the plan information, the method of acquisition is not limited and can be any method. Furthermore, the construction plan may need to be changed depending on working conditions such as the size of the cross section and the type of rock, and the work results of past construction projects. The information related to changes in the construction plan is included in the information on the construction plan for each work unit, and is included in the plan information. Therefore, when the information acquisition unit acquires information to revise the construction plan, for example, it acquires it as plan information. In this case, the method of acquisition can be any method that can be used for analyzing the situation in the device 20A, as described above.

[0092] Furthermore, the work information includes, for example, the start time, stop time, and work duration of the machine based on the status determination information. The work information used by the status analysis unit for analysis is, for example, information stored in a database for managing the progress of construction work. The method of using the work information is, for example, the same as in the case of the planning information, and any method that can be used for analyzing the situation in the device 20A is acceptable. Therefore, for example, the information acquisition unit may acquire the work information. The method of acquisition may be, for example, input of information via the input unit of the device 20A, or acquisition of information from an external device, and any method is acceptable. In order to compare the planning information and the work information, for example, information regarding the work unit to which the work information corresponds is required. Therefore, for example, the construction manager checks the work information and registers performance confirmation information, which is the result of checking the work results. The performance confirmation information includes, for example, information regarding the work unit to which the machine's work is related. Specifically, for example, when a day's work is completed, or at the time of a supervisor change, the supervisor registers information related to the work unit that was performed up to that point, such as the support structure number. This makes it possible to identify which work unit the work information corresponds to, and the planning information and the work information become comparable. The acquisition of the work information is not limited to the examples given above. The setting of the work unit may be, for example, automatically assigned to the work information based on the time assigned to the work unit. Thus, the setting of the work unit may be any method that allows for the identification of the work unit corresponding to the work information. Furthermore, the performance confirmation information is not limited to information related to the work unit, for example, but may also include information related to work conditions such as cross-sections and rock types confirmed based on the work results. And, similar to the case of the work information, the information acquisition unit may acquire the performance confirmation information. Furthermore, the method of acquisition may be any method, such as inputting information via the input unit of this device 20A, or acquiring information from an external terminal.

[0093] The situation analysis unit 23, for example, as described above, analyzes the status of the tunnel construction based on the plan information and work information for the corresponding work unit. The situation analysis unit 23 then generates analysis result information as a result of the analysis. The analysis result information compares the plan information with the corresponding work information. For example, the content may be information that displays the plan content and work results side by side. For example, the display may be a bar chart to make it easy to visually grasp the start time and end time. The analysis result information may also display, for example, the discrepancy in the start time, the discrepancy in the time required for the work, etc. The analysis result information may also display, for example, any omissions in the work. Thus, the analysis result information may have any content and format as long as it allows for an understanding of the situation of the actual work compared to the plan.

[0094] For example, the analysis result output unit of the device 20A may output the analysis result information generated by the situation analysis unit 23. The method of outputting the analysis result information is, for example, displaying it on a monitor provided to the construction manager. The output method is not limited to this, and may be any method, such as outputting to a mobile terminal, outputting to an external terminal, or outputting to a dedicated database.

[0095] The following diagrams, from Figure 10 to Figure 12, illustrate a specific example of the work management support method using the device 20A. Note that the following description is just one example of a specific flow; as mentioned above, the device 20A and the work management support method in this embodiment are not limited to the following description, and the work management support method in this embodiment is not limited to the use of the device 20A.

[0096] Figure 10 shows an example of planning information. The construction manager registers the planning information, for example, from the registration screen, which is the input unit of this device 20A. Figure 10(A) shows the screen displaying the registered planning information. When registering the planning information, the construction manager enters, for example, the support structure number and selects a support structure pattern according to the work content. In Figure 10(A), the planning information is registered so that the work of the support structure number, which is the work unit of the construction plan, is performed sequentially, rather than as a plan on an hourly basis. In other words, for example, it is registered so that as soon as the work of support structure number No. 1 is completed, the work of support structure number No. 2 will be performed. In Figure 10(B), for example, the work content and scheduled work time for support structure pattern A are displayed as specific work from 7:00 AM to 12:00 PM, along with the work name and scheduled required time, and the scheduled work time is displayed in a bar chart. The time at which the work will be performed is displayed in a bar chart. In Figure 10(A), for example, when the support structure number is selected as support pattern A, the contents of Figure 10(B) are reflected, and the period is set from 7:00 AM to 12:00 PM on April 1, 2023. Based on the registration by the construction manager, the information acquisition unit of this device 20A acquires, for example, the plan information described above. This plan information is used, for example, for analysis by the situation analysis unit 23.

[0097] Figure 11 shows an example of work information. The information acquisition unit of this device 20A acquires, for example, the start time and stop time of each machine based on the status determination information. Figure 11 is a performance confirmation screen that displays the acquired information as a bar chart. For example, the construction manager completed work No. 1 at 11:55 AM on April 1, 2023, and registered the completion in the double-circled section of the performance confirmation screen in Figure 11. In Figure 11, the section shown in the black bar chart represents the performance information related to No. 1. This performance information is acquired, for example, by the information acquisition unit of this device 20A. This performance information is then used, for example, for analysis by the status analysis unit 23.

[0098] Figure 12 shows an example of analysis results information. The bar chart in the upper part of Figure 12, where the work date, start, end, and work time are blank, displays the planned information. The lower part, where the work date and other information are entered, represents actual information, for example. In this way, by displaying planned information and actual information side by side, the discrepancy between the construction plan and the actual results can be visually grasped, and the construction manager can easily understand the status of the construction.

[0099] According to this disclosure, the status of machinery used for tunnel construction can be determined more accurately. Furthermore, the work management support device of this embodiment can visually display the status of tunnel construction based on, for example, planned information and actual information for the corresponding work unit. For this reason, the work management support device of this embodiment is useful, for example, for work management by construction managers.

[0100] [Embodiment 6] Embodiment 6 is another example of the work management support device according to the present disclosure.

[0101] This document describes another example of the work management support device related to this disclosure (hereinafter also referred to as "Device 20B"). The configuration (situation analysis unit 23) and hardware configuration of Device 20B are the same as those of Device 20A described in Embodiment 5, so the descriptions in Figures 7 and 8 can be used with reference. Although not shown in Figure 7, Device 20B may include, for example, an input unit, an information acquisition unit, other output units, an analysis result output unit, a display unit and / or a storage unit, as well as a work performance output unit.

[0102] Next, with reference to Figure 13, another example of the work management support method according to this disclosure will be described below. The work management support method of this embodiment is implemented, for example, using the aforementioned device 20B, as follows. Note that the work management support method of this embodiment is not limited to the use of the aforementioned device 20B.

[0103] First, the device 20B executes steps S21 to S22, for example, in the same manner as steps S21 to S22 in Embodiment 5.

[0104] Next, the situation analysis unit 23 in the device 20B analyzes the status of the tunnel construction based on the planning information and work information for the corresponding work unit, for example, as in Embodiment 5, and generates analysis result information (S23a, situation analysis step). Furthermore, the situation analysis unit 23 generates work performance information for each work unit over a certain period of time, for example, based on the work information (S23b, situation analysis step). Note that the steps of generating the analysis result information (S23a) and generating the work performance information (S23b) are not limited to the order shown in Figure 13, for example, and the order of the steps may be reversed or performed simultaneously. The work performance information includes, for example, information regarding the work performance of the machinery corresponding to the work unit, such as the start time, stop time, and work time of the machinery. As in the case of the device 20A in Embodiment 5, the situation analysis unit 23 can generate work performance information, for example, based on the work information, including the start time, stop time, and work time of the machinery used in the tunnel construction. Furthermore, the situation analysis unit 23 can, for example, statistically organize the past history of the work performance information to generate work performance history for a certain period as work performance information. The work performance information can, for example, display seven days' worth of history in a single table. The certain period is not limited to, for example, seven days, and can be set arbitrarily. The period can be, for example, one day, or it can be set immediately after the completion of the work, or it can be set arbitrarily. In addition, the work performance information can be displayed in any way, such as a bar chart, a display of the total working time for the machine, or a display of work performance for each machine.

[0105] In this embodiment, the work performance output unit of the device 20B may, for example, output the work performance information generated by the situation analysis unit 23. The method of output is the same as, for example, the output of analysis result information by the device 20A in Embodiment 5, so the explanation therein can be used.

[0106] The following example of the specific processing of the work management support method using the device 20B is shown using Figure 14. Note that the following description is just one example of a specific flow, and as mentioned above, the device 20B and the work management support method of this embodiment are not limited to the following description, and the work management support method of this embodiment is not limited to the use of the device 20B.

[0107] First, the acquisition of work information is the same as in the case of the device 20A in Embodiment 5 described above. An example of the performance information acquired by the device 20B is the same as in Figure 11 described above. The situation analysis unit 23 can generate work performance information based on the performance information. Figure 14 is an example of work performance information. Figure 14(A) is a bar graph showing the total work time for each machine by day and by work unit. Also, on the right side of Figure 14(A), the average work time for 7 days is displayed. Also, in Figure 14(A), the breakdown for each machine is displayed within the bar graph. Figure 14(B) is, for example, a section of Figure 14(A) showing the breaker. In this way, the device 20B can create information in a format that allows for statistical confirmation of work performance and is easy to visually confirm.

[0108] According to this disclosure, the condition of machinery used for tunnel construction can be determined more accurately. Furthermore, the work management support device of this embodiment can, for example, statistically summarize work performance over a certain period. This allows work managers to grasp, for example, trends in work conditions, and can be used for more appropriate work management.

[0109] [Embodiment 7] Embodiment 7 is yet another example of the work management support device of the present disclosure.

[0110] The work management support device related to this disclosure (hereinafter also referred to as "the device 20C") will be described with reference to Figure 15. Figure 15 is a block diagram showing an example of the configuration of the device 20C. As shown in Figure 15, the device 20C includes, for example, a warning information output unit 24 in addition to the configuration of the device 20A described in Embodiment 5. In the device 20C, the configuration, including the hardware configuration, is the same as that of the device 20A in Embodiment 5, except for the inclusion of, for example, the warning information output unit 24, and the explanations of Figures 7 and 8 can be referred to.

[0111] Next, another example of the work management support method relating to this disclosure will be described based on the flowchart in Figure 16. The work management support method of this embodiment is implemented as follows, for example, using the device 20C shown in Figure 15. Note that the work management support method of this embodiment is not limited to the use of the device 20C shown in Figure 15.

[0112] First, the apparatus 20C of this embodiment executes S21 to S22, for example, in the same manner as S21 to S22 of Embodiment 5.

[0113] Next, the status analysis unit 23 of the device 20C in this embodiment analyzes the status of tunnel construction based on the planning information and work information in the corresponding work unit, similar to the case of Embodiment 5, and generates analysis result information (S23c, status analysis step). Furthermore, the status analysis unit 23 generates warning information in at least one of the following cases: for example, when the working time of the machine within the work unit is outside the range defined in the work type information, and when the work order of the machine within the work unit differs from the order defined in the work type information (S23d, status analysis step). The work type information includes, for example, information that defines the work content categorized according to the content of construction for each work unit. In this way, for example, a warning can be issued if the work deviates from the standard based on the work type. The warning, for example, when the working time of the machine within the work unit is outside the range defined in the work type information, displays a message indicating that the work is behind schedule or ahead of schedule. Furthermore, the aforementioned warning may indicate, for example, that the work may not be completed if the order of operations of the machines within the work unit differs from the order specified in the work type information. The content of the warning is not limited to this and may be set arbitrarily.

[0114] Next, the warning information output unit 24 outputs the warning information, for example (S24, warning information output step). The method of output is, for example, display on a monitor, but it may also be an audible notification, and the method is not limited to any other method.

[0115] As a modification of this embodiment, the status analysis unit 23 of the device 20C of this embodiment may, for example, generate an alternative work type warning information indicating that the work in the work unit may have been performed based on the alternative work type if the working time of the machine within the work unit is outside the range defined in the work type information and within the range defined in other work types. In this case, the status analysis unit 23 can generate the alternative work type warning information by, for example, comparing it with other work types. When alternative work type warning information is generated, the warning information output unit 24 outputs the alternative work type warning information, for example.

[0116] According to this disclosure, the status of machinery used for tunnel construction can be determined more accurately. Furthermore, the work management support device of this embodiment can, for example, issue necessary warnings if the work deviates from a standard work type. Therefore, the work management support device of this embodiment is useful, for example, for proper work management.

Specifically, the program of this embodiment is a program that causes a computer to execute, for example, a procedure for acquiring status determination information, a procedure for generating work information, and a procedure for analyzing the situation.

[0119] Furthermore, the program of this embodiment can also be described as a program that causes a computer to function, for example, as a procedure for acquiring state determination information, a procedure for generating work information, and a procedure for analyzing the situation.
