Description

Embodiments of the present invention relate to a ground investigation data transfer system and a ground improvement construction data transfer system.

Ground investigation involves measuring the penetration resistance of the ground in situ using a ground investigation device such as a Swedish sounding tester, measuring its hardness, softness, compactness, and composition of soil layers to estimate the bearing capacity of the soil. It is. The foundation of the building is selected according to the results of this ground investigation. For example, if it is determined that the ground is soft, a cement-based solidifying agent is made into a slurry state and mechanically mixed and stirred while being injected into the target ground, solidifying the soil into columns and strengthening the ground. Ground improvement work is being carried out. In order to construct buildings that are safe and secure in the future, the reliability of ground survey results is of paramount importance, and falsification of ground survey data should be strictly prohibited.

The ground investigation data generated by the ground investigation machine is once collected at a data center (server device) via a USB memory or internet line, and distributed to a PC as appropriate, and a ground investigation report is generated for each surveyed property. is created and submitted to the client. In the flow of this data, data falsification can occur at various stages, such as the data generation stage in the ground surveying machine, the uploading stage from the ground surveying machine to the server device, and the stage of creating the ground survey report.

As ground surveying equipment becomes fully automated, the possibility that data will be tampered with at the data generation stage is decreasing. The stage of creating a ground investigation report is where editing and processing of the ground investigation data is required, so data falsification is most likely to occur, but the original data is stored in the data center, and this original It is possible to easily verify whether or not data has been tampered with by checking the consistency with the data, and it is relatively easy to identify the tamperer, so realistically the possibility of data tampering at this stage is low. low.

On the other hand, before uploading the ground survey data generated by the ground survey machine to the server device, we check the ground survey data and basically avoid any non-responsible causes such as misalignment of survey points, malfunction of the ground survey machine, data loss, etc. Mobile information processing terminals such as laptops and smartphones are often brought to the investigation site because they can determine on the spot whether the investigation needs to be redone. In this case, the ground survey data will be uploaded to the server device via the mobile information processing terminal. The mobile information processing terminal has functions that allow copying of ground survey data, as well as data editing and processing, so the possibility of data being tampered with on this mobile information processing terminal is comparatively high. It can be said that it is highly accurate.

However, since data tampering on mobile information processing terminals is done at the survey site, and the tampered ground survey data is stored as original data on the server device, there is a high probability that the tampering will be discovered. Currently, there is no such thing, and there is no way to verify it.

Similar problems can occur at the stage of uploading various construction data such as torque, cement milk injection amount, cumulative rotation speed, press-in pressure, excavation depth, excavation speed, and excavation load to the server device.

The purpose is to suppress data tampering when uploading soil survey data files and construction data files generated by soil survey machines and soil improvement construction machines to a server device.

The ground investigation data transfer system according to this embodiment transfers a ground investigation data file generated by an external ground investigation machine to an external server device. The ground survey data transfer system consists of a wireless communication module installed in a ground survey machine, a mobile information processing system that is connected to the wireless communication module based on short-range wireless communication standards, and connected to a server device via an Internet line. It is equipped with a terminal. The wireless communication module has an input section that inputs the ground survey data file from the ground survey machine, an internal storage section that stores the input ground survey data file as the input ground survey data file, and an input section that stores the input ground survey data file from among the stored ground survey data files. A list of unincorporated ground investigation data files from which investigation data files have been excluded and which have not been imported is sent to the mobile information processing terminal, and the ground investigation data is stored in response to a transmission request from the mobile information processing terminal. and a wireless communication module transmitting section that transmits unincorporated ground survey data files among the files to the mobile information processing terminal. The mobile information processing terminal includes an operation section operated by an operator, a receiving section that receives the unimported list and the ground survey data file from the wireless communication module , and a display section that displays the received unimported list. Regarding the ground survey data file selected to be imported from the wireless communication module only on the unimported list displayed via the operation unit so that the imported ground survey data file cannot be imported again. It has a first transmitter that transmits a transmission request to the wireless communication module, and a second transmitter that transmits the ground survey data file received from the wireless communication module to the server device.

Hereinafter, a ground survey data transfer system according to this embodiment will be described with reference to the drawings.

As shown in FIG. 1, the ground investigation data transfer system according to the present embodiment is a system that transfers ground investigation data generated by an external ground investigation machine 1 to an external server device 7. A wireless communication module 3 installed in a control device (control box) 13 is connected to the wireless communication module 3 under a short-range wireless communication standard such as Bluetooth (registered trademark), and is connected to a server device 7 via an Internet line 10. The mobile information processing terminal 5 is connected to the mobile information processing terminal 5.

The ground investigation machine 1 includes, for example, a Swedish sounding automatic penetration tester body (ground investigation machine body) 11, which measures penetration resistance in order to investigate the hardness and softness of the soil, compaction, soil quality, and soil layer structure in situ. It is composed of a control device 13 that controls the machine body 11. The ground surveying machine main body 11 includes a rod, a stand that supports the rod perpendicularly to the ground, a weight for applying a load of 50 kg, 75 kg, 100 kg, etc. to the rod, a rotation mechanism that drives the rod to rotate around an axis, and detects penetration depth. It consists of sensors, etc. The load WSW and half-rotation speed Na required for the rod to penetrate are measured as penetration resistance along with the depth. The control device 13 controls the ground investigation machine main body 11 and generates ground investigation data representing the correspondence between depth and penetration resistance based on the sensor output. The wireless communication module 3 is directly connected by wire to the serial port of the control device 13, and sequentially inputs the ground survey data through this serial interface.

The mobile information processing terminal 5, which is typically a laptop computer, smartphone, or tablet terminal, receives ground investigation data from the control device 13 of the ground investigation machine 1 via the wireless communication module 3, and transmits the received ground investigation data to the ground investigation device. It is transmitted to the server device 7 as an investigation data file. The server device 7 receives ground survey data files from a plurality of mobile information processing terminals 5, centrally stores them, and distributes the ground survey data files in accordance with a request from an external information processing terminal 9 such as a personal computer. The information processing terminal 9 creates a ground investigation report for each property to be investigated. The ground investigation report is provided to a client terminal (not shown).

The ground investigation data transfer system according to the present embodiment is a system that is placed between the ground investigation machine 1 and the server device 7 and relays the ground investigation data, and the mobile information processing terminal 5 independently intervenes between them. Instead, the functions of the wireless communication module 3 and the mobile information processing terminal 5 are differentiated and complement each other to realize relay processing.Also, as will be described in detail later, by setting functional constraints, there is no chance of data tampering. In addition, the date and time of transmission/reception (intake) of the ground survey data file between the wireless communication module 3 and the mobile information processing terminal 5 (intake date and time) and from the mobile information processing terminal 5 to the server. By recording the date and time of transmission (transfer, upload) of ground survey data to the device 7 (transfer date and time), the purpose is to psychologically reduce the desire to falsify data.

Here, "taking in" means that the mobile information processing terminal 5 requests the wireless communication module 3 to receive the ground survey data file. Further, "transfer" means that the mobile information processing terminal 5 transmits the ground survey data taken in from the wireless communication module 3 to the server device 7 as a ground survey data file.

As shown in FIG. 2, the wireless communication module 3 is not equipped with a display device such as a liquid crystal display or an input device such as a keyboard or a mouse, and communicates with the control unit 31 via the control/data bus 32 the file creation unit 33, A storage unit (internal module storage unit) 34, a table management unit 35, an unimported list creation unit 36, a data input unit 37 functioning as a serial interface, and a short-range wireless communication unit 38 such as Bluetooth (registered trademark) are connected. Become.

The file creation section 33 creates a ground investigation data file having a predetermined data structure based on the ground investigation data inputted from the data input section 37, for example, using measurement points as units. The ground survey data file contains attribute information such as file identification number, location information of the measurement point (GPS positioning information), measurement date and time, and ID of the person in charge of the measurement survey, in the data body in which penetration resistance values are associated with depths. It will be attached. The storage unit 34 records ground survey data files, management tables to be described later, and the like. As shown in Figure 5, the management table includes the "survey property name" item, the "data file identification number" item that identifies the ground investigation data file, and the "unread" item that distinguishes whether the ground investigation data file has been imported or not. "Imported/Imported flag" item, "Import date and time" item that represents the date and time when the ground survey data file was imported into the mobile information processing terminal 5, and "Import date and time" item that represents the date and time when the soil survey data file was transferred (updated) to the server device 7. It consists of the “transfer date and time (update date and time)” item.

The table management unit 35 is responsible for updating the management table, and mainly manages each ground survey data file by distinguishing whether it has been imported into the mobile information processing terminal 5 or not. Specifically, the table management unit 35 receives the receipt confirmation (import confirmation) of the ground survey data file from the mobile information processing terminal 5, and changes the "unimported/imported flag" item and "imported flag" in the management table. Update the "Import date and time" item as needed. The table management unit 35 updates the "transfer date and time" item of the management table at any time upon receipt of the transfer log of the ground survey data file to the server device 7 from the mobile information processing terminal 5.

The unimported list creation section 36, triggered by the input of the command for importing the ground investigation data file on the mobile information processing terminal 5, queries the management table and collects the plurality of ground investigation data stored in the storage section 34. The unimported ground survey data files are identified among the files, and an unimported list consisting of attribute information such as the survey property name, identification number, and measurement date and time regarding the identified unimported ground survey data files is created.

Under the control of the control unit 31, the short-range wireless communication unit 38 transmits the unimported list created by the unimported list creation unit 36 to the mobile information processing terminal 5, and also sends the unimported list created by the unimported list creation unit 36 to the mobile information processing terminal In the step, the ground survey data file selected on the unimported list is transmitted to the mobile information processing terminal 5.

As shown in FIG. 3, the mobile information processing terminal 5 is connected to the control unit 51 via a control/data bus 52 in a storage unit (internal storage ) 53, a display section 54 such as a liquid crystal panel, a display control section 55 that generates a display screen and supplies it to the display section 54, an operation section 56 such as a touch panel for tapping the command buttons displayed on the display section 54, and data. A processing section 57, a short-range wireless communication section 58 such as Bluetooth (registered trademark), and a mobile wireless communication section 59 are connected. The data processing unit 57 develops the ground investigation data in the ground investigation data file into a text format or processes it into a columnar diagram or the like. The data processing unit 57 does not have processing functions related to changing, overwriting, or copying the contents of the ground survey data file. At the same time, the display control unit 55 generates a plurality of types of display screens related to the process of importing and uploading the ground survey data file under the control of the control unit 51, but these display screens include information on how to change, overwrite, and copy the contents. Such command buttons are not displayed.

Under the control of the control unit 51 , the short-range wireless communication unit 58 transmits to the wireless communication module 3 a notification that a capture command has been input via the operation unit 56 , and also sends a notification to the wireless communication module 3 that a capture command has been input via the operation unit 56 . Functions as a transmitting unit (first transmitting unit) that transmits identification information regarding the ground survey data file to be imported selected on the list to the wireless communication module 3, and also receives an unimported list from the wireless communication module 3. It also functions as a receiving unit that receives from the wireless communication module 3 the ground survey data file to be imported selected on the unimported list. Under the control of the control unit 51, the mobile radio communication unit 59 collectively transmits (transfers) all the ground survey data files received from the wireless communication module 3 and stored in the storage unit 53 to the server device 7. ) functions as a transmitter (second transmitter).

FIG. 4 shows the flow of the ground survey data import process and transfer process (upload process) according to this embodiment. When a ground investigation is performed using the ground investigation device 1 (step S1), ground investigation data (sometimes simply referred to as investigation data) is generated at any time (step S2). As shown in Figure 18, the ground survey data includes attributes such as the measurement number, measurement date and time, and measurement position, as well as the load WSW and half-rotation speed Na necessary for the rod to penetrate, as well as the depth as well as the penetration resistance. Contains the data body. In addition, when the rod penetrates only by the load, it is written as "scuttling". Also, when the penetration speed is relatively slow, it is written as "osoi", and when it is relatively fast, it is written as "hayai".

The ground investigation data generated by the processor of the control device 13 of the ground investigation machine 1 is transmitted to and stored in the internal storage unit via an internal transmission path in a serial format such as Serial ATA. In parallel with this operation, the data is input in serial form to the data input section 37 of the wireless communication module 3 via a transmission line branched from the internal transmission line, a serial port, and a serial cable. The input ground survey data is edited into a ground survey data file for each measurement position by the file creation unit 33 (step S3), and is stored in the storage unit 34 (step S4). The ground survey data file consists of a data body in which a plurality of penetration resistances are associated with depths, and attribute information such as measurement number, measurement position, measurement date and time is attached. That is, all the ground investigation data generated by the control device 13 of the ground investigation machine 1 is input to the wireless communication module 3 and stored as a ground investigation data file.

When newly storing the ground survey data file in the storage unit 34, the management table is updated by the table management unit 35 (step S5). As shown in Figure 5, the management table includes a "survey property name" item, a "data file identification number" item that identifies the ground investigation data file, and an "unimported" item that distinguishes whether the ground investigation data file has been imported or not. /Imported Flag” item, “Import Date and Time” item that represents the date and time when the ground survey data file was imported into the mobile information processing terminal 5, and “Import Date and Time” item that represents the date and time that the soil survey data file was transferred (updated) to the server device 7. It consists of ``transfer date and time (update date and time)'' items. When adding information regarding a new ground investigation data file to the management table, the investigation property name item and data file identification number item are extracted from the attribute information of the ground investigation data file and newly written to the management table. In the example of FIG. 5, the identification numbers a1 to a8 of eight ground survey data files having the same survey property but different measurement positions and the respective survey property names are newly added. Initially, the uncaptured/captured flag is set to a value "0" representing a non-captured state, and the capture date and time and the transfer date and time (update date and time) are left blank.

In order to execute the process of importing and transferring the ground survey data file from the wireless communication module 3 to the mobile information processing terminal 5, the importing and transmitting program is started in the mobile information processing terminal 5. FIG. 6 shows an example of the initial screen. The initial screen generated by the display control unit 55 displays bibliographic information such as the survey number and survey name, as well as a ground survey data file labeled "Survey import" from the wireless communication module 3 to the mobile information processing terminal 5. An import process command button for the surveyor to input an instruction to execute the import process, and a process for transferring the ground survey data file from the mobile information processing terminal 5 to the server device 7 labeled "transfer (upload)". A survey import command button is included for the survey person to input execution instructions. The number of imported files, the number of imported files that have been transferred to the server device 7, and the number of untransferred files that have not yet been transferred are also written on the investigation import command button. In addition, when the mobile information processing terminal 5 is equipped with a photographing means, it includes a photographing command button labeled "Photograph" for the investigator to input an instruction to execute the photographing process, and a "Checklist" command button is included. It includes a checklist command button for displaying a check sheet for the surveyor to check the surrounding conditions and site conditions of the measurement position marked with "," and for the surveyor to input an instruction to execute the check.

When the import processing command button on the initial screen is tapped via the operation unit 56 and the import processing command is thereby input (step S11), information indicating that the import processing command has been input is transmitted via short-range wireless communication. It is transmitted to the wireless communication module 3 via the communication unit 58. In the wireless communication module 3, upon receiving information indicating that a capture processing command has been input, the table management section 35 queries the management table in the storage section 34 under the control of the control section 31, and the management table of the storage section 34 is checked. The identification number of the ground survey data file is specified (step S12). An unimported list (a list of unimported ground survey data files) containing the identification number and measurement date and time of each identified unimported ground survey data file is generated by the unimported list creation unit from the management table. 36 (step S13). As a specific example, an unimported list is created regarding eight ground survey data files identified by identification numbers a1 to a8. The created unimported list is transmitted to the mobile information processing terminal 5 via the short-range wireless communication unit 38 (step S14).

As illustrated in FIG. 7, the unimported list received by the mobile information processing terminal 5 is displayed on its display unit 54 as a list of unimported data files (step S15). As illustrated in FIG. 8, the person in charge of the investigation operates the operation unit 56 to select one or more pieces of ground to be imported from the wireless communication module 3 to the mobile information processing terminal 5 from the displayed unimported list. A survey data file is selected (step S16). In the example of FIG. 8, three ground survey data files identified by identification numbers a5, a6, and a7 are selected as objects to be imported. When the "import" command button on the screen is tapped, a command to import the selected ground survey data file from the wireless communication module 3 to the mobile information processing terminal 5 is input. Identification numbers a5, a6, and a7 identifying the ground survey data files to be imported are transmitted from the mobile information processing terminal 5 to the wireless communication module 3 together with a transmission request.

When the wireless communication module 3 receives the identification numbers a5, a6, and a7 together with the file transmission request, the wireless communication module 3 responds to the three grounds specified by the identification numbers a5, a6, and a7 under the control of the control unit 31. The survey data file is read from the storage unit 34 and transmitted to the mobile information processing terminal 5 via the short-range wireless communication unit 38 (step S17). The control unit 51 of the mobile information processing terminal 5 stores these received ground survey data files (a5, a6, a7) in the storage unit 53, and also stores the identification numbers a5, a6, a7 of the received ground survey data files. and the date and time of their import together with a confirmation of receipt. Upon completion of the import, a list of imported data files is displayed on the display unit 54 as illustrated in FIG.

When the wireless communication module 3 receives the identification numbers a5, a6, and a7 together with confirmation of receipt of the files, the management table is updated by the table management unit 35 under the control of the control unit 31 in response to the identification numbers a5, a6, and a7 (step S19). ). As illustrated in the middle part of FIG. 5, the unimported/imported flags for the three ground survey data files with identification numbers a5, a6, and a7 are rewritten to flag “1” indicating that they have been imported, and The delivery date and time will be listed.

The person in charge of the investigation returns to the initial screen shown in FIG. 10 by tapping the "return" command on the captured data file list screen shown in FIG. 9. On this initial screen, next to the survey import command button, there is a message indicating that the number of imported files is 3, that the number of imported files that have been transferred to the server device 7 is 0, and that no files have been transferred yet. It is displayed that the number of untransferred files is 3.

When the investigator taps the command button labeled "Transfer (Upload)" on the initial screen of FIG. 10 via the operation unit 56, a file transfer instruction is input (step S21). When a file transfer instruction is input, all untransferred ground survey data files (a5, a6, a7) are read from the storage unit 53 under the control of the control unit 51, and the mobile radio communication unit 59 is read out. The information is transmitted (transferred) all at once to the server device 7 via the server (step S22). When the transfer is completed, a list of imported data files with the status of these three ground survey data files (a5, a6, a7) updated to "transferred" is displayed, as illustrated in FIG. 11. When the "return" command button in FIG. 11 is tapped, the screen returns to the initial screen illustrated in FIG. 12. This initial screen shows that the number of imported files is 3, the number of imported files that have been transferred to the server device 7 is 3, and the number of untransferred files that have not been transferred yet is 0. This will be displayed.

Upon completion of the transfer, a transfer confirmation is transmitted from the mobile information processing terminal 5 to the wireless communication module 3 along with the identification numbers a5, a6, a7 of the ground survey data file and their transfer date and time. In the wireless communication module 3, in response to receiving the transfer confirmation, the management table is updated by the table management unit 35 under the control of the control unit 31 (step S23). As illustrated in the lower part of FIG. 5, the transfer dates and times regarding the three ground survey data files with identification numbers a5, a6, and a7 are listed.

Here, after importing the three ground survey data files with identification numbers a5, a6, and a7 from the wireless communication module 3 to the mobile information processing terminal 5, a further import processing command is sent to the mobile information processing terminal 5 by the person in charge of the survey. When input via the operation unit 56 of , a7) are excluded, and a list of five unimported ground survey data files with identification numbers a1 to a4 and a8 is transmitted. According to the unimported list, the display unit 54 of the mobile information processing terminal 5 displays only the identification numbers a1 to a4, a8 and the measurement date and time regarding the five unimported ground survey data files, as shown in FIG. will be listed.

Therefore, the range of selection of files to be imported by the person in charge of investigation is limited to only the listed data files that have not yet been imported. In other words, in the ground investigation data transfer system according to this embodiment, it is not possible to import the already imported ground investigation data file into the mobile information processing terminal 5 again.In other words, the ground investigation data file cannot be imported at once. Limited.

FIG. 14 shows, for example, the import data file displayed on the display unit 54 when the ground survey data file with identification number a8 is selected, its import is instructed, and the import of the ground survey data file (a8) is completed. Shows a list of data files. In this list, the ground survey data file (a8) is added to the list in FIG. 7, and its status is "not transferred". The status of the other imported ground survey data files (a5 to a7) is “transferred”, that is, the status has been uploaded to the server device 7. When the display screen of FIG. 14 returns to the initial screen, as shown in FIG. is "3", and the number of untransferred files that have not yet been transferred is "1".

When the command button labeled "Transfer (Upload)" on this initial screen is tapped and a file transfer instruction is input, the untransferred ground survey data file (a8) is read from the storage unit 53, It is transmitted (transferred) to the server device 7 via the mobile wireless communication unit 59. When the transfer is completed, as illustrated in FIG. 16, the number of transferred files including this ground survey data file (a8) is updated to "4" and the number of untransferred files is updated to "0".

Note that the data processing unit 57 of the mobile radio communication unit 59 is equipped only with the function of executing processing related to display on the ground investigation data file, and it is equipped only with the function of executing processing related to display on the ground investigation data file, and the data processing unit 57 is equipped with only the function of executing display-related processing on the ground investigation data file, and the data processing unit 57 is equipped with only the function of executing processing related to display on the ground investigation data file, and the data processing unit 57 is equipped with only the function of executing processing related to display on the ground investigation data file, and the data processing unit 57 is equipped with only the function of executing processing related to display on the ground investigation data file. , overwrite it, and copy it further. For example, the data processing unit 57 generates a histogram from the ground survey data file and displays it as illustrated in FIG. Display as shown.

As described above, the ground investigation data transfer system according to the present embodiment is interposed between the ground investigation machine 1 and the server device 7, and is divided into the wireless communication module 3 and the mobile information processing terminal 5. , a wireless communication module 3 is installed in the ground surveying machine 1, and this wireless communication module 3 stores all the ground survey data files generated by the ground surveying machine 1, while the mobile information processing terminal 5 is equipped with a wireless communication module 3. Information regarding unimported ground survey data files (unimported list) is provided from the module 3, and a ground research data file to be imported from the wireless communication module 3 to the mobile information processing terminal 5 is selected only on the unimported list. be able to. The mobile information processing terminal 5 cannot re-import a ground survey data file that has already been imported. In other words, the ground survey data file can be loaded into the mobile information processing terminal 5 only once. Therefore, by forcibly falsifying the data by using some means to make the ground survey data file of one measurement position belong to another measurement position, the ground survey data file of one measurement position is used as the ground survey data file of another measurement position. Even if the surveyor neglects to perform ground survey work at another measurement location, it is not possible to re-import the soil survey data file at a certain measurement location, so if the soil investigation data file at a certain measurement location exists. Therefore, the data cannot be transferred to the server device 7. As a result, it is necessary to re-implement the ground investigation work at a certain measurement position. Therefore, such falsification of the measurement position is suppressed. Additionally, data falsification involves the use of some means to forcibly rewrite the main body of the data in the ground survey data file in order to unfairly contract ground improvement from the client or to show the client that ground improvement is unnecessary. It is not impossible to imagine that. Since the ground survey data file can only be loaded into the mobile information processing terminal 5 once, there is a non-zero possibility that the ground survey data file will be lost when the data itself is rewritten or overwritten. In that case, the ground survey data file cannot be re-imported, so a resurvey is required. Therefore, it is possible to reduce the desire of the investigator to falsify data, and as a result, falsification of the data itself can be suppressed.

Furthermore, since the wireless communication module 3 is not equipped with an operation section or a display section, it is impossible for the person in charge of the survey to check the ground survey data file using the wireless communication module 3, or to tamper with the data. The storage unit 34 of the wireless communication module 3 stores the original ground survey data input from the ground survey device 1 simply converted into a file. Therefore, a work manager or the like can extract the original ground survey data file from the storage unit 34 of the wireless communication module 3 under special authority and check it with the ground survey data file transferred to and stored in the server device 7. This makes it easy to verify whether data has been tampered with. Therefore, it is possible to reduce the desire of the investigator to falsify data, and as a result, falsification of the data itself can be suppressed.

Furthermore, the storage unit 34 of the wireless communication module 3 stores the transmission date and time (intake date and time) of the ground survey data file from the wireless communication module 3 to the mobile information processing terminal 5, and also the transmission date and time of the ground survey data file from the mobile information processing terminal 5 to the server device 7. Since the date and time of uploading the ground survey data (transfer date and time) is recorded, the surveyor cannot change the import date and time and the transfer date and time. The possibility of data falsification can be suspected relatively easily due to an excessively long time interval, etc., and therefore the investigator's desire to falsify data can be reduced.

Note that although the ground investigation data transfer system has been described above, this embodiment can also be applied to a ground improvement construction data transfer system. In this case, "ground investigation machine" will be read as "soil improvement construction machine", "ground investigation machine body" will be read as "soil improvement construction machine body", and "ground survey data" will be read as "construction data". , "measurement position" will be read as "work position", and "person in charge of investigation" will be read as "person in charge of ground improvement construction". Common ground improvement methods include columnar improvement and steel pipe pile construction. Various sensors installed on the ground improvement construction machine generate various construction data such as torque, cement milk injection amount, cumulative rotation speed, press-in pressure, excavation depth, excavation speed, and excavation load. These construction data are stored in the data center (server device) in the same way as the ground survey data. The construction data generated by the soil improvement construction machine is transferred to the server device via the soil improvement construction data transfer system. The procedure for transferring data to the server device via is the same, and the configuration of the soil improvement construction data transfer system is also the same as that of the ground investigation data transfer system described above.
