Description

The present invention relates to a ground evaluation information prediction system, a ground evaluation information prediction method, and a computer program.

Traditionally, when constructing a structure on a piece of land, an issue is whether the ground on that piece of land is strong enough to withstand the weight of the structure, etc. For this reason, an evaluation of the ground on that piece of land is carried out (for example, Patent Document 1). If the result of the ground evaluation shows that the ground is not strong enough, work to strengthen the ground is carried out before the structure is constructed.

FIG. 2 is a schematic block diagram showing a specific example of the functional configuration of the terminal device 10. The terminal device 10 is configured using information devices such as a smartphone, a tablet, a personal computer, or a dedicated device. The terminal device 10 includes a communication unit 11, an input unit 12, an output unit 13, a storage unit 14, and a control unit 15.

The communication unit 11 is a communication device. The communication unit 11 may be configured as, for example, a network interface. The communication unit 11 communicates data with other devices via the network 70 in accordance with the control of the control unit 15. The communication unit 11 may be a device that performs wireless communication or a device that performs wired communication.

The input unit 12 is configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), buttons, and a touch panel. The input unit 12 is operated by the user when inputting the user's instructions to the terminal device 10. The input unit 12 may be an interface for connecting the input device to the terminal device 10. In this case, the input unit 12 inputs an input signal generated in the input device in response to the user's input to the terminal device 10. The input unit 12 may be configured using a microphone and a voice recognition device. In this case, the input unit 12 acquires an acoustic signal generated by the user's speech, performs voice recognition on the words spoken by the user, and inputs character string information of the recognition result to the terminal device 10. The voice recognition process may be executed by the control unit 15. The input unit 12 may be configured in any way as long as it is configured to input the user's instructions to the terminal device 10.

The output unit 13 outputs information in a form that can be recognized by the user. The output unit 13 may be, for example, an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The output unit 13 may be an interface for connecting the image display device to the terminal device 10. In this case, the output unit 13 generates a video signal for displaying image data and outputs the video signal to the image display device connected to the output unit 13. The output unit 13 may be a device for outputting sound such as a speaker. The output unit 13 may be an interface for connecting an audio output device such as a speaker or a headphone to the terminal device 10. In this case, the output unit 13 generates an audio signal for reproducing audio data and outputs the audio signal to the audio output device connected to the output unit 13. The output unit 13 may be configured as a touch panel integrated with the input unit 12.

The storage unit 14 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 14 stores data used by the control unit 15. The storage unit 14 stores data required when the control unit 15 performs processing.

The control unit 15 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). The control unit 15 functions by the processor executing a program. All or part of the functions of the control unit 15 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as flexible disks, optical magnetic disks, ROMs, CD-ROMs, and semiconductor storage devices (e.g., SSDs: Solid State Drives), and storage devices such as hard disks and semiconductor storage devices built into computer systems. The above program may be transmitted via a telecommunications line.

The control unit 15 may execute, for example, an application installed in its own device (terminal device 10). A specific example of such an application is an application provided to the terminal device 10 as a dedicated application for the ground evaluation information prediction system 100. Another specific example of such an application is a web browser application. Such an application may be installed in the terminal device 10 in advance, or may be downloaded each time the ground evaluation information prediction process is executed. For example, when implemented as a web browser application, the terminal device 10 may download and execute the application from a device specified by the web server (for example, the web server itself or another server) in response to the terminal device 10 connecting to a specific web server. The control unit 15 operates according to the program of the application being executed.

For example, when information transmitted from the ground evaluation information prediction device 30 is received by the communication unit 11 via the network 70, the control unit 15 generates screen data based on the received information and causes the output unit 13 to display the screen data. Such screen data includes images and characters indicating the information transmitted from the ground evaluation information prediction device 30. For example, when information transmitted from the ground evaluation information prediction device 30 is received by the communication unit 11 via the network 70, the control unit 15 generates voice data based on the received information and causes the output unit 13 to output the voice data.

Figure 3 is a schematic block diagram showing a specific example of the functional configuration of the learning device 20. The learning device 20 is configured using an information processing device such as a personal computer or a server device. The learning device 20 includes a communication unit 21, a storage unit 22, and a control unit 23.

The communication unit 21 is a communication device. The communication unit 21 may be configured as, for example, a network interface. The communication unit 21 communicates data with other devices via the network 70 in accordance with the control of the control unit 23. The communication unit 21 may be a device that performs wireless communication or a device that performs wired communication.

The memory unit 22 is configured using a memory device such as a magnetic hard disk device or a semiconductor memory device. The memory unit 22 stores data used by the control unit 23. The memory unit 22 may function, for example, as a ground evaluation teacher data memory unit 221, a preprocessed teacher data memory unit 222, and a trained model memory unit 223.

The ground evaluation teacher data storage unit 221 stores teacher data used in the learning process executed by the learning device 20. The teacher data stored in the ground evaluation teacher data storage unit 221 includes evaluation target information, which is an explanatory variable, and ground evaluation information, which is an objective variable. Specific examples of evaluation target information will be explained in more detail. Evaluation target information includes, for example, at least one of location information, construction progress information, and floor information. Specific examples of each type of information will be explained below.

The location information may be, for example, information (e.g., a character string) indicating the address of the land to be evaluated. The location information may be expressed using latitude and longitude.

The development progress information may be a numerical value indicating the time (e.g., the number of years) that has passed since development was carried out on the land to be evaluated. The development progress information may be information indicating which of a plurality of categories that directly or indirectly indicate the period of time that has passed since development was carried out on the land to be evaluated belongs to. Such categories may be defined using, for example, three categories: "less than one year", "reconstruction", and "other". "Less than one year" indicates that less than one year has passed since development was carried out in the past. "Reconstruction" indicates that a structure was built on the land in the past. In other words, "reconstruction" indicates that development has been carried out on the land in the past. "Other" indicates that it is unknown whether a structure was built on the land in the past or whether development has been carried out. "Other" may include the fact that it is clear that no development has been carried out on the land in the past.

The building information may be information indicating the weight of the building planned to be constructed on the land being evaluated, or information indicating the floors and structure of the building.

As described above, the ground evaluation information may include either or both of the ground countermeasure information and the evaluation-related information. The ground countermeasure information may be, for example, information indicating whether or not countermeasures are necessary for the ground being evaluated. The ground countermeasure information may be, for example, information indicating which of the two categories, "spread foundation" or "requires countermeasures," the ground belongs to, or may be a numerical value indicating the possibility of belonging to each category. "Spread foundation" indicates that no prior ground countermeasures are necessary for construction planned on the land. "Requires countermeasures" indicates that prior ground countermeasures are necessary for construction planned on the land.

Other specific examples of ground countermeasure information may include information showing the cost of countermeasures on the ground being evaluated, or information showing the time required to implement countermeasures on the ground being evaluated.

Other examples of ground countermeasure information may include information indicating the content of countermeasures required for the ground being evaluated. Specific examples of such information include information indicating the type of construction method used as the countermeasure and information indicating the depth of the bearing layer. As the type of construction method, for example, the values of "columnar improvement system", "prefabricated pile (bearing pile)", "prefabricated pile (friction pile)", "cast-in-place pile", "wooden pile", "crushed stone pile" and "other" may be used. The bearing layer depth indicates the depth of the piles driven into the ground as a ground countermeasure.

Specific examples of evaluation-related information may include values indicating the depth of ground investigation and the strength of the ground. The depth of ground investigation is information indicating the depth to which investigation would be required if an actual investigation were conducted on the ground being evaluated. A specific example of such an investigation is the SWS (screw weight penetration test).

The preprocessed teacher data storage unit 222 stores preprocessed teacher data. The preprocessed teacher data is teacher data including information obtained by performing preprocessing on the soil evaluation teacher data. For example, the preprocessed teacher data may be data in which some or all of the values included in the soil evaluation teacher data have been replaced with other values by preprocessing. For example, the preprocessed teacher data may be data to which information obtained by preprocessing using some or all of the values included in the soil evaluation teacher data has been added. The preprocessed teacher data may include one or more of topography information and soil information obtained by preprocessing using, for example, position information. Both the topography information and the soil information are used as explanatory variables.

The topographical information is information that indicates the topography of the land to be evaluated. The topographical information may be, for example, information that indicates the magnitude of the slope. Specific examples of such information include the maximum slope angle and the minimum slope angle. The topographical information may be, for example, information that indicates the altitude. The topographical information may be information within a predetermined range centered on the land to be evaluated. For example, information within a 20 meter radius or information within a 50 meter radius centered on the land to be evaluated may be used.

The soil information is information that indicates the soil of the land to be evaluated. The soil information may be, for example, information that indicates the type of soil. The soil information may be, for example, a value that indicates the possibility that the soil contains humus, or may be information that indicates the degree of humus contained in the soil.

The trained model memory unit 223 stores trained models obtained by a learning process using the teacher data stored in the ground evaluation teacher data memory unit 221 and the preprocessed teacher data stored in the preprocessed teacher data memory unit 222.

The control unit 23 is configured using a processor such as a CPU and a memory. The control unit 23 functions as an information control unit 231, a pre-processing control unit 232, and a learning control unit 233 by the processor executing a program. All or part of the functions of the control unit 23 may be realized using hardware such as an ASIC, a PLD, or an FPGA. The above program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as flexible disks, optical magnetic disks, ROMs, CD-ROMs, and semiconductor storage devices (e.g., SSDs), and storage devices such as hard disks and semiconductor storage devices built into a computer system. The above program may be transmitted via a telecommunications line.

The information control unit 231 controls the input and output of information. For example, the information control unit 231 acquires ground evaluation teacher data from other devices (information processing devices or storage media) and records it in the ground evaluation teacher data storage unit 221. For example, the information control unit 231 transmits the learned model stored in the learned model storage unit 223 to other devices (for example, the ground evaluation information prediction device 30).

The preprocessing control unit 232 generates preprocessed teacher data by performing a predetermined preprocessing on the ground evaluation teacher data. The preprocessing control unit 232 may acquire latitude and longitude values based on information indicating an address, for example. The preprocessing control unit 232 may acquire information indicating an address based on latitude and longitude, for example. The preprocessing control unit 232 may acquire topographical information based on positional information, for example. In this case, the storage unit 22 may associate the positional information with the topographical information and store it in advance. The preprocessing control unit 232 may acquire topographical information corresponding to the positional information based on the information stored in the storage unit 22. The preprocessing control unit 232 may acquire topographical information corresponding to the positional information from another information processing device that associates the positional information with the topographical information and stores it in advance. The preprocessing control unit 232 may acquire soil information based on positional information, for example. In this case, the storage unit 22 may associate the positional information with the soil information and store it in advance. The preprocessing control unit 232 may acquire soil information corresponding to the positional information based on the information stored in the storage unit 22. The pre-processing control unit 232 may obtain soil information corresponding to the location information from another information processing device that previously stores the location information in association with the soil information.

The learning control unit 233 executes a learning process using the preprocessed teacher data stored in the preprocessed teacher data storage unit 222. As a specific example of such a learning process, for example, supervised learning for classification such as a support vector machine, a random forest, or a neural network may be used. The learning control unit 233 generates a learned model for outputting a target variable (for example, ground countermeasure information) based on any one or more pieces of information (for example, location information) of the input explanatory variables, for example, by performing supervised learning. The learning control unit 233 records the generated learned model in the learned model storage unit 223. The learned model obtained by the learning control unit 233 may be transmitted to the ground evaluation information prediction device 30 and recorded in the ground evaluation information prediction model storage unit 321 of the ground evaluation information prediction device 30. Such a learned model can obtain a target variable (for example, ground countermeasure information) as an output by providing any one or more pieces of information (for example, location information) of the explanatory variables as an input.

Figure 4 is a flowchart showing a specific example of processing of the learning device 20. First, the information control unit 231 acquires soil evaluation teacher data (step S101). The soil evaluation teacher data may be input by, for example, a user (administrator) of the learning device 20, may be acquired by communication from another information device, or may be acquired from a recording medium connected to the learning device 20. The preprocessing control unit 232 performs a predetermined preprocessing on the soil evaluation teacher data (step S102). The learning control unit 233 executes a learning process using the preprocessed teacher data, and records the learned model in the learned model storage unit 223 (step S103).

Figure 5 is a schematic block diagram showing a specific example of the functional configuration of the ground evaluation information prediction device 30. The ground evaluation information prediction device 30 is configured using an information processing device such as a personal computer or a server device. The ground evaluation information prediction device 30 includes a communication unit 31, a memory unit 32, and a control unit 33.

The communication unit 31 is a communication device. The communication unit 31 may be configured as, for example, a network interface. The communication unit 31 communicates data with other devices via the network 70 in accordance with the control of the control unit 33. The communication unit 31 may be a device that performs wireless communication or a device that performs wired communication.

The storage unit 32 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 32 stores data used by the control unit 33. The storage unit 32 may function as, for example, a ground evaluation information prediction model storage unit 321.

The ground evaluation information prediction model storage unit 321 stores a ground evaluation information prediction model used by the ground evaluation information prediction unit 333 when performing ground evaluation information prediction processing. The ground evaluation information prediction model may be configured using information of a learned model that has been generated in advance by a learning process, for example. Such a learning process may be executed, for example, by another device (for example, the learning device 20), or may be executed by the device itself (the ground evaluation information prediction device 30). The ground evaluation information prediction model does not necessarily have to be generated by a learning process. The ground evaluation information prediction model may be configured, for example, using a lookup table that associates evaluation target information with ground evaluation information, or may be configured in another manner.

The control unit 33 is configured using a processor such as a CPU and a memory. The control unit 33 functions as an information control unit 331, a pre-processing control unit 332, and a ground evaluation information prediction unit 333 by the processor executing a program. All or part of the functions of the control unit 33 may be realized using hardware such as an ASIC, a PLD, or an FPGA. The above program may be recorded on a computer-readable recording medium. Examples of computer-readable recording media include portable media such as flexible disks, optical magnetic disks, ROMs, CD-ROMs, and semiconductor storage devices (e.g., SSDs), and storage devices such as hard disks and semiconductor storage devices built into a computer system. The above program may be transmitted via a telecommunications line.

The information control unit 331 acquires evaluation target information from other devices such as the terminal device 10. The information control unit 331 transmits information indicating the prediction results obtained by the ground evaluation information prediction unit 333 (e.g., ground countermeasure information) to other devices such as the terminal device 10. Such exchange of information between the information control unit 331 and other devices may be performed, for example, by communication using the communication unit 31.

The preprocessing control unit 332 acquires preprocessed information by performing a predetermined preprocessing on the evaluation target information acquired by the information control unit 331. The preprocessing performed by the preprocessing control unit 332 is similar to the preprocessing performed when generating a trained model used by the ground evaluation information prediction unit 333. In other words, the processing performed by the preprocessing control unit 332 on the evaluation target information is the same as the processing performed by the preprocessing control unit 232 on the ground evaluation teacher data. The preprocessing control unit 332 acquires preprocessed information by performing such preprocessing. For example, the preprocessing control unit 332 may acquire one or more of topographical information and soil information by performing preprocessing using position information.

The ground evaluation information prediction unit 333 performs a ground evaluation information prediction process using the ground evaluation information prediction model stored in the ground evaluation information prediction model storage unit 321 and the preprocessed information. The ground evaluation information prediction process predicts ground evaluation information. In this embodiment, the ground evaluation information prediction unit 333 predicts either or both of the ground countermeasure information and the evaluation-related information. The ground evaluation information prediction unit 333 outputs prediction results regarding at least either or both of the ground countermeasure information and the evaluation-related information.

Figure 6 is a flowchart showing a specific example of processing of the ground evaluation information prediction device 30. First, the information control unit 331 acquires evaluation target information from the terminal device 10 (step S201). The preprocessing control unit 332 acquires preprocessed information by performing preprocessing on the evaluation target information (step S202). The ground evaluation information prediction unit 333 performs ground evaluation information prediction processing using at least the preprocessed information (step S203). The ground evaluation information prediction unit 333 transmits information indicating the prediction result to the terminal device 10 (step S204).

In the ground evaluation information prediction system 100 configured in this manner, it is possible to predict ground evaluation information in a shorter time by using evaluation target information. Specifically, it is as follows. In the ground evaluation information prediction system 100, a learning process is performed using multiple preprocessed teacher data generated using multiple pieces of evaluation target information, and a learned model is obtained. Then, in the ground evaluation information prediction system 100, new evaluation target information to be predicted is obtained, and preprocessing is performed based on this to obtain ground evaluation information. The preprocessed information is correlated with the ground evaluation information.

For example, the need for and content of ground measures often correlate with the strength of the ground. For example, measures may be necessary if the ground is relatively weak, and may not be necessary if the ground is relatively strong. The content of the measures required also changes depending on the weakness of the ground. The strength of the ground also changes depending on the location of the land. Therefore, it is believed that a high correlation will occur between location information and ground measure information depending on such characteristics. It is also believed that a high correlation will occur between the topography or soil of the land and the strength of the ground. Therefore, it is believed that a high correlation will occur between soil information or topography information and ground measure information depending on such characteristics.

For example, the need for ground countermeasures and the details of those countermeasures often correlate with past development work on that ground. For example, if ground has been developed recently, there is a high possibility that countermeasures will not be necessary, and if ground has not been developed, there is a high possibility that countermeasures will be necessary. Also, even if ground development has been carried out in the past, the more time that has passed, the more likely it is that countermeasures will be necessary. Therefore, it is thought that a high correlation will arise between construction progress information and ground countermeasure information depending on these characteristics.

For example, the need for and content of ground measures often correlate with the weight of the building to be constructed on that land. For example, a lighter building is more likely to not require measures, while a heavier building is more likely to require measures. The weight of a building may be expressed as the required bearing capacity of the ground. The more stories a building has, the heavier it is. For this reason, it is believed that a high correlation will arise between building information and ground measure information depending on such characteristics.

These correlations are common not only to ground countermeasure information, but also to evaluation-related information. In other words, where ground requires more costly ground countermeasures, there is a high possibility that the investigation will also be more costly. For example, where ground requires deeper driving of piles, the investigation will also need to be conducted deeper. Due to these characteristics, it is thought that there will be a high correlation between location information, construction progress information, building information, and evaluation-related information.

The ground evaluation information prediction device 30 may receive a prediction processing request from an information processing device other than the terminal device 10. FIG. 10 is a diagram showing a modified example of the ground evaluation information prediction system 100. In the ground evaluation information prediction system 100 shown in FIG. 10, the ground evaluation information prediction device 30 communicates with the information providing device 19. The information providing device 19 receives input information (including, for example, evaluation target information) from the terminal device 10, and provides output information corresponding to the input information to the terminal device 10. In the process of generating output information from the input information, the information providing device 19 acquires ground evaluation information from the ground evaluation information prediction device 30. Specifically, this is as follows.

For example, when the information providing device 19 receives evaluation target information from the terminal device 10, it transmits the received evaluation target information to the ground evaluation information prediction device 30. The ground evaluation information prediction device 30 predicts ground evaluation information based on the received evaluation target information and transmits the prediction result to the information providing device 19. When the information providing device 19 receives the ground evaluation information, it generates provided information based on the received ground evaluation information. For example, the information providing device 19 may provide the terminal device 10 with candidate companies that can carry out the ground countermeasures based on the ground countermeasures information included in the ground evaluation information. The information providing device 19 transmits the generated provided information to the terminal device 10.

The application running on the terminal device 10 may not be intended to predict ground evaluation information itself, but may be an application that provides a user with information obtained by performing processing using the results of the ground evaluation information prediction. Such an application may be, for example, an application that performs processing using an API (Application Programming Interface) provided by the ground evaluation information prediction device 30. In this case, the output unit 13 may output other information obtained by processing using the ground evaluation information, instead of information indicating the information itself (ground evaluation information) obtained from the ground evaluation information prediction device 30.

The above describes an embodiment of the present invention in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and includes designs that do not deviate from the gist of the present invention.
