Summary of the Invention

Problems to be Solved by the Invention

[0004] In the technique of Patent Document 1, data observed, measured, and analyzed at the site is shared using the management system. At that time, it has been time-consuming to perform format unification and adjustment so that the shared parties can easily recognize it. Further, when the user manually performs information search, extraction of necessary information, information processing, and information output, there has been a workload.

[Modes for carrying out the invention]

[0008] Hereinafter, an embodiment of an information management system, an information management method, and an information management program will be described with reference to Figures 1 to 8. In this embodiment, the information management system CS1 will be described as being used for managing information related to tunnel construction. As shown in Figure 1, this embodiment uses user devices 10 and management devices 20 that are interconnected via a network.

[0009] (Description of hardware configuration) Figure 2 illustrates the hardware configuration of the information processing device H10, which constitutes the user device 10 and the management device 20. The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is just one example, and it can also be implemented with other hardware.

[0010] Communication device H11 is an interface that establishes a communication path with other devices and performs data transmission and reception, such as a network interface or a wireless interface.

[0011] The input device H12 is a device that accepts input of various types of information, such as a mouse or keyboard. The display device H13 is a display that shows various types of information. The storage device H14 is a storage device that stores data and various programs for executing various functions of the user device 10 and the management device 20. Examples of storage devices H14 include ROM, RAM, and hard disks.

[0012] The processor H15 controls the various processes in the user device 10 and the management device 20 using programs and data stored in the memory device H14. Examples of processor H15 include CPUs and MPUs. This processor H15 loads programs stored in ROM or the like into RAM and executes various processes for each operation.

[0013] Processor H15 is not limited to performing software processing for all the processes it executes. For example, processor H15 may include a dedicated hardware circuit (e.g., an application-specific integrated circuit: ASIC) that performs hardware processing for at least a part of the processes it executes.

[0014] (System Configuration) Next, each function of the information management system will be described using FIG. 1. The user device 10 is a computer terminal used by a person in charge of tunnel construction (user).

[0015] The management device 20 is a computer system that supports the management of tunnel construction. This management device 20 includes a control unit 21, a user information storage unit 22, a term information storage unit 23, and a management information storage unit 24.

[0016] The control unit 21 supports the process management at the construction site of the construction work. For this purpose, the control unit 21 functions as a registration unit 211, a search unit 212, and an output unit 213 that execute a registration step, a search step, an output step, etc. by executing an information management program.

[0017] The registration unit 211 executes a process of registering information related to tunnel construction. The search unit 212 executes a process of searching for information in the management information storage unit 24 using the information acquired from the user device 10. The output unit 213 executes a process of generating target information using the search result and outputting it to the user device 10.

[0018] As shown in FIG. 3, user management information 220 is recorded in the user information storage unit 22. This user management information 220 is recorded when user registration is performed. Information regarding the user ID, attributes, and terminal ID is recorded in the user management information 220.

[0019] The user ID is an identifier for identifying each user. The site ID is an identifier used to identify the construction site that this user is involved with. Attributes are information about this user, such as their name, affiliation, and job title. The terminal ID is information used to identify the user device 10 that this user is using.

[0020] As shown in Figure 4, the term information storage unit 23 stores classification information 231 and display management information 232 for terms used by the user, serving as a term dictionary. This classification information 231 and display management information 232 are recorded when terms used at construction sites are registered.

[0021] Classification information 231 records information about stages, major categories, subcategories, and terms. The stages represent on-site status information indicating the progress of construction. Examples include design, excavation, lining, and others.

[0022] The major categories record information related to the tasks performed within each stage. For example, in the "Design" stage, this includes core boring information, reference point information, initial design, seismic exploration, etc. In the "Excavation" stage, this includes face observation, underground measurements, groundwater seepage information, forward exploration, etc.

[0023] Sub-items record information about the items used in the main items. The terminology refers to search terms used in sub-items. This also includes terms that express these sub-items using other words. This terminology is then used as a keyword for searching, and information is extracted from the management information storage unit 24. For example, under the stage "During excavation" and the major item "Face observation," there is a sub-item "Face photograph." In addition to "Face photograph," the term "Face image" is also recorded.

[0024] Display management information 232 records instruction words and information regarding the display method. Instructional words are terms that indicate how something should be displayed. The display method corresponds to the instruction word. The output unit 213 performs processing and editing of the information extracted from the management information storage unit 24 according to this display method. For example, in the case of "Display tunnel faces from A to C", the output unit 213 displays the tunnel face images numbered A to C in order, corresponding to the instruction word "Display tunnel faces". Also, in the case of "Display the amount of settlement at the top of tunnels from A to C", the output unit 213 generates a graph in which the amount of settlement at the top of tunnels numbered A to C are arranged in order, corresponding to the instruction word "amount of settlement at the top of tunnels".

[0025] As shown in Figure 5, the management information storage unit 24 records various types of information related to the tunnel construction. These types of information include, for example, ground data 24a, tunnel data 24b, and measurement quality data 24c. Ground data 24a contains information about the current topography and geology of the site where the tunnel will be constructed. Ground data 24a includes topographic file 241 and geological file 242. This ground data 24a includes the site ID and data related to topography and geology. Location information is associated with each topographic feature and geological feature in this ground data 24a. By using the location information of ground data 24a, a 3D model of topography and geology (ground model) can be generated.

[0026] Site ID data is an identifier used to identify a construction site. The terrain file 241 records a 3D model of the ground surface. This terrain data can be obtained from sources such as elevation data from the Geospatial Information Authority of Japan or actual measurement data (point cloud data) from a 3D scanner.

[0027] Geological file 242 contains a three-dimensional model of the boundary surface of the geological layers. This geological data is geological information measured using methods such as boring, and records the information from the geological survey data described in the design documents.

[0028] Tunnel data 24b contains tunnel design information. This tunnel data 24b includes the tunnel design file 243 and the construction progress file 244. Tunnel design file 243 contains data related to the site ID, tunnel alignment, tunnel cross-sectional shape, tunnel members, and construction plan. Tunnel data 24b associates location information with the tunnel shape. By using the tunnel alignment and tunnel cross-sectional shape from tunnel data 24b, a 3D model of the tunnel (tunnel design model) can be generated.

[0029] Site ID data is an identifier used to identify a construction site. Tunnel alignment data records the coordinates of the planned tunnel layout (start point to end point) in three-dimensional space.

[0030] The tunnel cross-section shape data records the cross-sectional view of the tunnel. By using this tunnel cross-section shape data, the cross-sectional shape at each location along the planned route can be identified. The tunnel member data records the tunnel members (objects) used in tunnel construction relative to the planned line (coordinates). The construction plan data records the planned schedule for tunnel construction.

[0031] Construction progress file 244 records the site ID, construction location, and actual schedule (construction start date and construction end date).

[0032] The measurement quality data 24c includes the site ID, measurement location, and various measurement information during construction. The measurement quality data 24c records measurement files 245, cross-section measurement files 246, face observation image files 247, and face forward exploration result files 248, etc., associated with the site ID, measurement date and time, and measurement location (for example, coordinates of the planned line). By using the measurement location in this measurement quality data 24c, the three-dimensional arrangement of the measurement results in a virtual space can be identified.

[0033] Site ID data is an identifier used to identify a construction site. Measurement file 245 records data related to measurement results taken during daily construction management. Examples include internal displacement measurements, rock bolt axial force measurements, support structure stress measurements, sprayed concrete stress measurements, and underground displacement measurements.

[0034] The cross-sectional measurement file 246 records data related to the measurement results of the tunnel cross-section measured during construction. This cross-sectional measurement data includes observation results other than face observation, such as displacement, stress, axial force measurement, face condition, condition of the uncut surface, compressive strength, weathering state, proportion of fractured areas at the face, frequency of cracks, crack condition, groundwater seepage, etc.

[0035] The tunnel face observation image file 247 records images of the tunnel face cross-section taken during construction. These tunnel face observation images can be incorporated into the integrated model and displayed according to the measurement location. The face-forward exploration results file 248 records data related to the exploration results performed in front of the tunnel face during construction. In this embodiment, non-core drilling exploration, borehole observation, all-core boring, and underground seismic exploration are used as face-forward exploration methods.

[0036] Furthermore, by placing the ground model, tunnel design model, and measurement result model in the same 3D virtual space, it is possible to generate an integrated model that combines multiple pieces of information. (Information management processing) Figures 6 to 8 will be used to explain the information management process.

[0037] (Information registration process) First, we will explain the information registration process using Figure 6. Here, the control unit 21 of the management device 20 performs the information acquisition process (step S11). Specifically, the registration unit 211 of the control unit 21 acquires the file input to the user device 10.

[0038] Next, the control unit 21 of the management device 20 performs site and location identification processing (step S12). Specifically, the registration unit 211 of the control unit 21 uses the user information storage unit 22 to identify the site ID to be handled by the user using the user device 10. In this case, the terminal ID of the user device 10 can be used, or the user ID of the user who logged into the user device 10 can be used. Furthermore, the registration unit 211 obtains the location of the user device 10.

[0039] Next, the control unit 21 of the management device 20 performs the information registration process (step S13). Specifically, the registration unit 211 of the control unit 21 records the acquired file in the management information storage unit 24. In this case, the registration unit 211 associates location information with the file and records it in the management information storage unit 24. For example, if the acquired file contains location information, this location information is used. If the acquired file does not contain location information, the location of the user device 10 is used as the location information.

[0040] (Information output processing) Next, we will explain the information output process for the target information using Figures 7 and 8. First, Figure 7 will be used to explain the overview of the information output process for the target information. Here, when outputting the target information, the user's voice is acquired from the user device 10. In this case, the site to which the user using the user device 10 is involved is identified. Then, the management information storage unit 24 identifies the stage (construction progress) of this site. Keywords (search terms) are acquired by speech recognition of the person in charge's voice. These keywords include search words and instruction words. Then, files containing items corresponding to the search words are extracted from the site, user, and stage. Furthermore, the display method of the extracted files is determined using the instruction words, and the target information is output.

[0041] Figure 8 will be used to explain the details of the information output process. Here, the control unit 21 of the management device 20 performs the voice acquisition process (step S21). Specifically, when a user requests the output of target information, voice is input to the sound collection device (microphone) of the user device 10. In this case, the search unit 212 of the control unit 21 acquires the voice spoken by the person in charge from the user device 10.

[0042] Next, the control unit 21 of the management device 20 performs site identification processing (step S22). Specifically, the search unit 212 of the control unit 21 identifies the user of the user device 10. In this case, the user ID or terminal ID obtained from the user device 10 can be used. Then, the search unit 212 identifies the site that this user is in charge of using the user management information 220 in the user information storage unit 22.

[0043] Next, the control unit 21 of the management device 20 performs a stage identification process (step S23). Specifically, the search unit 212 of the control unit 21 identifies the progress status of the site using the construction progress status file 244 in the management information storage unit 24, and identifies the stage corresponding to the progress status.

[0044] Next, the control unit 21 of the management device 20 performs speech recognition processing (step S24). Specifically, the search unit 212 of the control unit 21 obtains the spoken text by performing speech recognition of the utterance.

[0045] Next, the control unit 21 of the management device 20 performs keyword identification processing (step S25). Specifically, the search unit 212 of the control unit 21 obtains keywords (nouns and verbs) by morphological analysis of the spoken text.

[0046] Next, the control unit 21 of the management device 20 performs a prediction process for target information using a term dictionary (step S26). Specifically, the search unit 212 of the control unit 21 identifies the search word (term) recorded in the classification information 231 of the term information storage unit 23 and the instruction word recorded in the display management information 232 based on the acquired keyword. Furthermore, the search unit 212 identifies the location information based on the acquired keyword. This allows the unit to predict the target information desired by the person in charge, according to the keywords included in the utterance.

[0047] Next, the control unit 21 of the management device 20 executes the process of acquiring the target information (step S27). Specifically, the output unit 213 of the control unit 21 extracts a file containing items corresponding to the search words (terms) of the classification information 231 from the management information storage unit 24. In this case, at a construction site, a file filtered by site ID and location is acquired. If the keywords do not include location-related keywords, the entire site is assumed to be represented.

[0048] For example, if the keyword does not include location information but does include keywords related to "work face images," all work face images for this site are retrieved from the management information storage unit 24 as target information. Furthermore, depending on the instruction word, if information processing is necessary to obtain the target information, calculation processing is performed using the information obtained from the management information storage unit 24.

[0049] For example, in the case of "settlement of the top surface from A (location) to B (location)," the keywords obtained are "A (location) to B (location)," "top surface," and "settlement." Next, measurement quality data 24c corresponding to A (location) to B (location) is obtained from the management information storage unit 24. Then, in the measurement file 245, the amount of settlement of the top surface is obtained in the order from A (location) to B (location), and a graph with the settlement amounts arranged in order is created as the target information.

[0050] Next, the control unit 21 of the management device 20 performs the output processing of the target information (step S28). Specifically, the output unit 213 of the control unit 21 outputs the target information to the user device 10.

[0051] According to this embodiment, the following effects can be obtained. (1) In this embodiment, the control unit 21 of the management device 20 performs information acquisition processing (step S11) and information registration processing (step S13). This allows users to efficiently share information without having to organize the data.

[0052] (2) In this embodiment, the control unit 21 of the management device 20 performs site and location identification processing (step S12). This makes it possible to register information corresponding to the location of the construction site.

[0053] (3) In this embodiment, the control unit 21 of the management device 20 performs voice acquisition processing (step S21), stage identification processing (step S23), and keyword identification processing (step S25). This makes it possible to efficiently acquire the target information.

[0054] (4) In this embodiment, the control unit 21 of the management device 20 performs a stage identification process (step S23). This makes it possible to obtain information according to the progress of the construction work. (5) In this embodiment, the control unit 21 of the management device 20 performs prediction processing of target information using a term dictionary (step S26). This makes it possible to obtain target information corresponding to the search word from the management information storage unit 24, which stores a variety of information. For example, even if there are variations in language notation at a construction site due to the customs of construction workers, the term dictionary can be used to address these variations in language notation. Furthermore, here, the desired location information is identified. For example, in tunnel construction, most site information is associated with one-dimensional coordinates along the tunnel's alignment, so the desired information corresponding to the location information can be obtained.

[0055] (6) In this embodiment, the control unit 21 of the management device 20 performs the process of acquiring the target information (step S27). This makes it possible to acquire the target information that has been edited or processed according to the instruction word.

[0056] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically. In the above embodiment, the control unit 21 of the management device 20 performs the information registration process (step S13). In this case, the user ID of the registrant and the location information of the user device 10 may be recorded in the management information storage unit 24, associated with a file. Alternatively, the information type may be associated with a file and recorded in the management information storage unit 24. In this case, the registration unit 211 of the control unit 21 recognizes the pattern of the file contents acquired from the user device 10 to identify the information type.

[0057] In the above embodiment, the information management system CS1 was described as being used for managing information related to tunnel construction. However, the information to be managed is not limited to information related to tunnel construction. It can be used when search terms or target information change depending on the situation at the site. In the above embodiment, the management information storage unit 24 records ground data 24a, tunnel data 24b, measurement quality data 24c, etc. The information recorded in the management information storage unit 24 is not limited to these.

[0058] In the above embodiment, the term information storage unit 23 stores classification information 231 and display management information 232 for terms used by the user. Here, the terms in the classification information 231 and the display management information 232 may be recorded for each user. In this case, the classification information 231 and display management information 232 corresponding to the user ID of the user device 10 are used in the information type prediction processing (step S26). This makes it possible to customize the target information for each user. The terms in the classification information 231 and the display management information 232 may also be recorded for each site. In this case, the classification information 231 and display management information 232 corresponding to the site ID are used in the information type prediction processing (step S26). This makes it possible to customize the target information for each user and each site.

[0059] In the above embodiment, the control unit 21 of the management device 20 performs a stage identification process (step S23). Here, the progress status of the site is identified using the construction progress status file 244 in the management information storage unit 24, and the stage corresponding to the progress status is identified. The method of identifying the stage is not limited to this. For example, in the sound acquisition process (step S21), ambient sounds contained in the sound acquired from the user device 10 may be used. Since the ambient sounds differ depending on the stage, each stage is identified by pattern recognition of the ambient sounds. In the above embodiment, the control unit 21 of the management device 20 executes voice acquisition processing (step S21), site identification processing (step S22) to keyword identification processing (step S25). The entity executing these processes is not limited to the management device 20. For example, some or all of the processes may be performed by the user device 10. Alternatively, the user device 10 may execute the target information acquisition processing (step S27). In this case, a term information storage unit 23 is provided in each user device 10.

[0060] In the above embodiment, the term information storage unit 23 stores classification information 231 and display management information 232 for terms used by the user. The management device 20 may also perform a dictionary creation process to register terms in the term information storage unit 23. In the above embodiment, the control unit 21 of the management device 20 performs the process of acquiring target information (step S27). Here, the location of the target information is identified using keywords included in the utterance. The method of identifying the location of the target information is not limited to this; for example, the current location identification means of the user device 10 may be used to identify the location, and the location of the target information may be identified in accordance with this location. In this case, range setting information that defines the range in which the target information is to be acquired according to the location can be used.

[0061] The dictionary creation process will be explained using Figure 9. First, the control unit 21 of the management device 20 executes the voice acquisition process (step S31) to the keyword identification process (step S35), similar to steps S21 to S25.

[0062] Next, the control unit 21 of the management device 20 executes the process of acquiring the target information created by the user (step S36). Specifically, the user uses the user device 10 to search for the desired file in the management information storage unit 24. Then, using the user device 10, the user creates the target information using the items contained in the file extracted from the management information storage unit 24. In this case, the registration unit 211 of the control unit 21 identifies the items contained in the extracted file from the user device 10.

[0063] Next, the control unit 21 of the management device 20 performs the process of generating teacher information (step S36). Specifically, the learning unit of the control unit 21 generates a combination (teacher information) of the keywords identified in the keyword identification process (step S35) and the items contained in the extracted file, and records it in the teacher information storage unit.

[0064] If a predetermined amount or more of teacher information is recorded, the control unit 21 of the management device 20 executes a learning process (step S37). Specifically, the learning unit of the control unit 21 learns the correspondence between items contained in the file and keywords contained in the utterances. For example, the learning unit calculates the frequency of occurrence of combinations of mutually related items and keywords and identifies combinations that occur frequently.

[0065] Next, the control unit 21 of the management device 20 executes the term dictionary registration process (step S38). Specifically, the learning unit of the control unit 21 records the learned keywords as terms, associating them with the stages, major categories, and subcategories of the classification information 231.

[0066] This allows for the efficient creation of the term information storage unit 23. Furthermore, the user device 10 may specify an editing and processing procedure for creating the target information and record it as an instruction word in the display management information 232.
