[0001] The present invention relates to an information management device, an information management program, and an information management system. [Background technology]

[0002] In order to manage the construction status of pile holes made by an excavator, an administrator acquires construction data from the pile driver and uploads the construction data and a report created based on the construction data to a server, thereby inspecting the quality of the construction (see, for example, Patent Document 1). There is also a method in which an SD card with wireless communication function is used to upload the construction data recorded on the SD card to a server via a repeater (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6315440 [Patent Document 2] JP 2018-145713 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Documents 1 and 2, the construction data is acquired once by an administrator, who then creates a form based on the construction data, so there is a possibility that the construction data and the form may be tampered with. An object of the present invention is to improve user convenience and prevent data tampering. [Means for solving the problem]

[0005] (1) According to one aspect of the present invention, an information management device mounted on a pile driver includes an acquisition unit, a creation unit, and a communication unit. The acquisition unit acquires construction data of the pile driver. The creation unit generates a form from the construction data. The communication unit wirelessly transmits the form. According to the above configuration (1), the report is wirelessly transmitted from the information management device to the manager terminal, so that the user does not have to extract the construction data from the information management device and create the report, improving the user's convenience. In addition, since the report is created by the information management device, the manager does not have to create the report based on the construction data, and data tampering can be suppressed.

[0006] (2) In some embodiments, in (1), The information management device further includes a reception unit that receives an instruction to select the construction data to be entered in the form from a manager terminal capable of wireless communication. The generation unit creates the form using the construction data selected in response to the selection instruction received by the reception unit. According to the above configuration (2), the construction manager can select from the construction data different construction data depending on the construction method used or different construction data that needs to be submitted for each construction site, so that the manager can create the report he or she desires.

[0007] (3) In some embodiments, in the above configuration (1), The information management device further includes a reception unit that receives an instruction to create the form from a wireless communication-enabled administrator terminal. The generation unit generates the form in response to the instruction to create the form received by the reception unit. According to the above configuration (3), the manager can create the form at a desired timing.

[0008] (4) In some embodiments, in the above configuration (1), The information management device further includes a reception unit and a conversion unit. The reception unit receives a request to confirm a construction status of the pile driver from an administrator terminal capable of wireless communication. The conversion unit converts the construction data in response to the confirmation request received by the reception unit. The communication unit wirelessly transmits the converted construction data to the administrator terminal. According to the above configuration (4), the manager can wirelessly receive construction data, for example, graphed by conversion processing, from the communication unit of the information management device. This allows the manager to grasp the progress of construction even when working in a location away from the information management device, thereby enabling efficient construction management.

[0009] (5) In some embodiments, in any one of the above configurations (1) to (4), The information management device further includes a connection control unit that distinguishes between a management application that the administrator terminal can log in to and a management application that a terminal other than the administrator terminal that is capable of wireless communication can log in to, and establishes a wireless connection. According to the above configuration (5), since it is possible to log in to the management device from a terminal other than the administrator, it is possible to prevent data tampering after construction is completed by a person other than the administrator checking the data during construction.

[0010] (6) In some embodiments, in any one of the above configurations (1) to (5), the communication unit transmits the document to a terminal other than the administrator in response to an instruction from an administrator terminal capable of wireless communication. According to the above configuration (6), it is possible to improve convenience for the user.

[0011] (7) In some embodiments, in any one of the above configurations (1) to (6), the communication unit notifies at least one of an administrator terminal capable of wireless communication and a terminal other than the administrator terminal when a specific event related to construction occurs. According to the above configuration (7), the administrator or the viewer only needs to check the administrator terminal or the viewer terminal when a specific event occurs, thereby realizing efficient management.

[0012] (8) In one embodiment of the present invention, an information management program running on a computer mounted on a pile driver causes the computer to function as an acquisition means for acquiring construction data of the pile driver, a creation means for creating a report from the construction data, and a communication means for wirelessly transmitting the report. According to the above configuration (8), it is possible to improve user convenience and prevent data tampering.

[0013] (9) An information management system according to one embodiment of the present invention includes an administrator terminal and an information management device mounted on a pile driver. The information management device includes an acquisition unit and a connection control unit. The acquisition unit acquires construction data of the pile driver. The connection control unit establishes a wireless connection with the administrator terminal in response to a request from the administrator terminal. The administrator terminal transmits an instruction to create a form to the wirelessly connected information management device. The information management device further includes a creation unit and a communication unit. The creation unit creates a form from the construction data in response to the instruction to create the form from the administrator terminal. The communication unit wirelessly transmits the form to the administrator terminal. According to the above configuration (9), it is possible to improve user convenience and prevent data tampering.

[0014] (10) In some embodiments, in the above configuration (9), The information management system includes a viewer terminal capable of only viewing the construction data and the form. The connection control unit establishes a wireless connection with the viewer terminal in response to a request from the viewer terminal. According to the above configuration (10), it is possible to improve user convenience and prevent data tampering. Effect of the Invention

[0015] According to the present invention, it is possible to improve user convenience and prevent data tampering. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an information management device, an information management program, and an information management system according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following embodiments, parts with the same numbers perform the same operations, and will not be described repeatedly.

[0018] The information management system according to this embodiment will be described with reference to the conceptual diagram of FIG. 1 includes three pile drivers 1A, 1B, and 1C, an administrator terminal 3, and a viewer terminal 4. Each of the pile drivers 1A to 1C is equipped with a main box 2 including an information management device 20 and a wireless communication device 25.

[0019] For ease of explanation, the pile drivers are illustrated with different alphabetical characters, but when no special distinction is required, they will be referred to as "pile driver 1." In addition, although the example in FIG. 1 shows three pile drivers, the number of pile drivers may be two or less, or four or more. Similarly, multiple administrator terminals 3 and multiple viewer terminals 4 may be present.

[0020] The pile driver 1 has a drilling rod that can move up and down, and drills a pile hole while rotating the drilling rod. Note that the structure of the pile driver 1 is similar to that of a general pile driver, so a detailed description thereof will be omitted.

[0021] The main box 2 mounted on the pile driver 1 includes an information management device 20 implemented by a computing device such as a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit), and a wireless communication device 25 having wireless communication capabilities. The main box 2 acquires construction data obtained while the pile driver 1 is performing construction, such as the excavation depth and the motor current value, and generates a ledger based on the construction data. The main box 2 is capable of wirelessly transmitting and receiving data via the wireless communication device 25.

[0022] The manager terminal 3 is, for example, a terminal such as a smartphone, a feature phone, a tablet PC, or a notebook PC. By wirelessly connecting to the pile driver 1, a request to view the construction data and an instruction to create a form are transmitted. The manager terminal 3 uses a browser function of the mobile terminal to display the construction data and forms acquired from the pile driver 1 on the screen of the manager terminal. Note that the manager terminal 3 is assumed to be a portable mobile terminal, but is not limited to this, and may be a desktop PC installed in a station or the like.

[0023] The viewer terminal 4 is a mobile terminal or a desktop PC similar to the administrator terminal 3. However, the functions of the viewer terminal 4 with respect to the information management device 20 are limited. For example, unlike the administrator terminal 3, the viewer terminal 4 cannot send a report creation instruction to the pile driver 1, and can only view construction data and reports.

[0024] Next, an example of the pile driver 1 according to this embodiment will be described with reference to Fig. 2. Fig. 2 shows the external appearance of the pile driver 1, and illustrates the main box 2 and sensors connected to the main box 2. An operation box 11, a display box 12, an auger control panel 13, a depth detector 14, and a flow rate detector 15 are each connected to the main box 2 by cables.

[0025] The operation box 11 is a control device for an administrator to give control instructions regarding construction, such as operations such as enlarging or reducing the head, air bleeding, starting measurement of construction data, and managing data such as calculations. Note that if the above-mentioned control instructions can be given to the pile driver 1 from the wirelessly connected administrator terminal 3, the operation box 11 does not need to be provided. The display box 12 has the same control function as the operation box 11, and is a control device for the operator of the pile driver 1. In addition, since the operations on the operation box 11 are also displayed on the display box 12, the operator can recognize the operations of the administrator on the screen by checking the display box 12.

[0026] The auger control panel 13 is a control device that controls the current value of the auger motor, switching of the rotation speed (high speed or low speed, etc.), detection of the rotation direction (forward rotation or reverse rotation), etc. Information regarding the current value, rotation speed, and rotation direction detected by the auger control panel 13 is transmitted to the main box 2. The depth detector 14 detects the excavation depth. The detected excavation depth is transmitted to the main box 2. The flow rate detector 15 detects the milk flow rate. The detected milk flow rate is transmitted to the main box 2.

[0027] Although not shown, the sensor values ​​acquired by the main box 2 may include the pile tip depth, the hydraulic oil flow rate, and the resistivity value of the milk.

[0028] Next, details of the main box 2 according to this embodiment will be described with reference to the block diagram of FIG. The main box 2 according to this embodiment includes an information management device 20 and a wireless communication device 25. The information management device 20 includes a processing circuit 21, a storage unit 22, and a communication interface 23, which are connected to each other via a bus.

[0029] The processing circuit 21 is realized by any one or a combination of a CPU, a GPU, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc. The processing circuit 21 includes a data acquisition unit 211, an instruction reception unit 212, a data conversion unit 213, a form creation unit 214, a connection control unit 215, and a wireless communication unit 216.

[0030] The data acquisition unit 211 acquires construction data indicating the construction status of the pile driver 1. The instruction receiving unit 212 receives a request to confirm the construction status of the pile driver 1 from the manager terminal 3 and the browser terminal 4. The instruction receiving unit 212 receives an instruction from the manager terminal 3 to select construction data to be entered in a form and an instruction to create the form.

[0031] The data conversion unit 213 converts the construction data from the start of the construction data acquisition to the time of receiving the confirmation request into data that can be provided to the administrator or the viewer, for example by graphing the data in a visually easy-to-read form. Specifically, for example, the data conversion unit 213 calculates the acquired raw construction data to convert it into numerical values, and creates a graph from the numerical values. Note that the conversion of the construction data is not limited to graphing, and any method of converting and providing the construction data may be used as long as the raw construction data does not exist on the administrator terminal 3 or the viewer terminal 4 side to prevent tampering. The form creation unit 214 creates a form from the construction data. That is, the form creation unit 214 creates a form with a graph by using the construction data that has been graphed.

[0032] The connection control unit 215 controls wireless connections with the administrator terminal 3 and the viewer terminal 4. If authentication by the connection control unit 215 is successful, a connection with the administrator terminal 3 or the viewer terminal 4 is established. The wireless communication unit 216 transmits the converted construction data and the created form from the wireless communication device 25 via the communication interface 23 to each terminal.

[0033] The storage unit 22 is composed of a hard disk drive (HDD), a solid state drive (SSD), etc., and acquires construction data. The construction data is assumed to include data such as a construction location, excavation date and time, excavator model information, time series data of instantaneous current value and integral current value of a motor, time series data of excavation depth, time series data of excavation speed, time series data of water supply amount, and time series data of milk flow rate, but is not limited to these, and may include data that can be acquired by the pile driver 1 and is necessary for creating a ledger.

[0034] The communication interface 23 is an interface conforming to a predetermined communication standard for wirelessly transmitting and receiving data between the information management device 20 and the administrator terminal 3 or the viewer terminal 4. As the communication standard, a wireless LAN (Local Area Network) conforming to Wi-Fi (registered trademark) is assumed, but a wireless network such as Bluetooth (registered trademark) may also be used.

[0035] The wireless communication device 25 is, for example, a wireless LAN router, a wireless LAN access point, or a Bluetooth module. The wireless communication device 25 forms a communication area to which the administrator terminal 3 or the viewer terminal 4 can be connected.

[0036] Next, a first operation example of the information management system according to this embodiment will be described with reference to the sequence diagram of FIG.

[0037] FIG. 4 is a sequence diagram relating to data transmission and reception between the manager terminal 3, the pile driver 1 including the information management device 20 in the main box 2, and the viewer terminal 4 from the start of construction to the creation of a form.

[0038] In the sequence diagrams of Figures 4 to 6, although in reality a wireless connection is made with a wireless communication device (assumed to be a Wi-Fi access point via wireless LAN here) connected to the main box 2, for convenience of explanation, it is expressed as "wirelessly connecting with the pile driver 1." Also, although data is controlled by each unit (each function) of the information management device 20 included in the main box 2, for convenience of explanation, it is expressed as each unit in the pile driver 1 executing processing.

[0039] In step S401, the administrator terminal 3 requests a wireless connection with the pile driver 1. Specifically, the administrator terminal 3 selects an SSID (Service Set Identifier) ​​set by the pile driver 1 to which the administrator terminal 3 wishes to wirelessly connect, and inputs a password. The SSID is an identifier that uniquely identifies a Wi-Fi access point set by the wireless communication device 25 stored in the main box 2.

[0040] In step S402, the connection control unit 215 in the pile driver 1 authenticates the connection request from the administrator terminal 3. It is assumed here that the password entered from the administrator terminal 3 is correct and authentication is successful. As a result, the connection control unit 215 establishes a wireless connection between the administrator terminal 3 and the main box 2 of the pile driver 1. After that, the administrator terminal 3 can access an administrator URL (Uniform Resource Locator) to open a management application screen that allows the administrator to give instructions to the information management device and view construction data. On the management screen, the administrator can perform various processes such as viewing construction data and creating graphs by giving instructions such as pressing or touching a button. It is assumed that the management application screen present in the administrator URL is written in HTML (Hyper Text Markup Language) and is in a format that can be operated without depending on specific software and applications if a browser function is available.

[0041] In step S403, the manager terminal 3 transmits a recording start instruction to the pile driver 1. In step S404, the instruction receiving unit 212 in the pile driver 1 receives a recording start instruction from the manager terminal 3, and the data acquiring unit 211 acquires multiple types of construction data from various sensors of the pile driver 1. Specifically, for example, current data including an instantaneous current value and an integral current value is acquired from the auger control panel 13, excavation depth data is acquired from the depth detector 14, and milk flow rate data is acquired from the flow rate detector 15 as multiple types of construction data.

[0042] In step S405, the viewer terminal 4 requests a wireless connection with the pile driver 1. The viewer terminal 4 selects the SSID set by the pile driver 1 to which the viewer terminal 4 wishes to wirelessly connect, and inputs the password. In step S406, the connection control unit 215 in the pile driver 1 authenticates the connection request from the viewer terminal 4. Here, since it is assumed that the password entered from the viewer terminal 4 is correct, the authentication is successful and the connection control unit 215 establishes a wireless connection between the viewer terminal 4 and the pile driver 1. Note that in the viewer terminal 4, in order to limit operations on the information management device 20, the viewer is made to access a viewer URL that is different from the administrator URL. When accessed via the viewer URL, the management application may be restricted so that, for example, only the function of viewing the construction data can be executed and instructions to generate reports or to start and end the recording of the construction data cannot be issued.

[0043] In order to restrict operations between the administrator and the viewer, an authentication means may be provided that requires login to operate the management application. Alternatively, if the connection control unit 215 can obtain information (such as a MAC address) that can identify the wirelessly connected terminal, a table that associates the MAC address with the type of terminal (administrator terminal 3 or viewer terminal 4) may be prepared in advance on the information management device 20 side, and the management application may be switched according to the type of the wirelessly connected terminal by referring to the table.

[0044] In step S407, the manager terminal 3 and the viewer terminal 4 transmit a request to the pile driver 1 to check the construction status. In step S408, when the instruction receiving unit 212 in the pile driver 1 receives a request to confirm the construction status from the manager terminal 3 and the viewer terminal 4, the data conversion unit 213 converts the construction data from the time when recording started to the time when the confirmation request was received. The wireless communication unit 216 in the pile driver 1 transmits the converted construction data to the manager terminal 3 and the viewer terminal 4, respectively. This allows the manager terminal 3 and the viewer terminal 4 to wirelessly receive the converted construction data, and allows the progress of the construction to be grasped in real time even when working in a place away from the information management device 20, thereby enabling efficient construction management. The administrator terminal 3 and the viewer terminal 4 may graph the received construction data such as current value, flow rate, and depth, and display the graph together with the data from the boring survey such as N value stored on the terminal side. The data from the boring survey such as N value may be stored in each terminal, and displayed on the terminal side together with the construction data. The data from the boring survey may be input and stored in advance on the information management device 20 side, and the information management device 20 may select the construction data and the corresponding data from the boring survey in response to an instruction from each terminal, and transmit the data to each terminal. This allows the construction data and the data from the boring survey to be displayed together on the terminal side.

[0045] In step S409, the manager terminal 3 transmits an instruction to create the form to the pile driver 1. This enables the manager to create the form at a desired timing. In step S410, when the instruction receiving unit 212 in the pile driver 1 receives an instruction to create a form from the manager terminal 3, the form creating unit 214 in the pile driver 1 creates a form.

[0046] When sending an instruction to create a form, the manager terminal 3 may send an instruction to select construction data to specify which of multiple types of construction data is to be used to create the form. When the instruction receiving unit 212 in the pile driver 1 receives an instruction to select construction data from the manager terminal 3, the instruction receiving unit 212 creates a form using the construction data selected based on the selection instruction. Specifically, when the selection instruction is an instruction to use construction data of an integral current value and an excavation depth, a form including the integral current value and the excavation depth may be generated. In addition, it may be possible to input predetermined information such as the title of the form, the site name, the address, the construction machine, and the design value from the manager terminal 3. The form creation unit 214 in the pile driver 1 reflects the information input from the manager terminal 3 when creating the form. This allows the manager to select from the construction data different construction data depending on the construction method or construction data that needs to be submitted differently for each construction site, so that the manager can create the form he or she desires.

[0047] In step S411, the wireless communication unit 216 in the pile driver 1 transmits the created form to the manager terminal 3. Note that the wireless communication unit 216 in the pile driver 1 may also transmit the form to other manager terminals 3 and the viewer terminal 4 when the manager terminal 3 issues an instruction to create a form. The other terminals to which the form is to be transmitted may be, for example, a terminal specified by the manager terminal 3 when issuing an instruction to create a form, or may be a terminal set by default. In step S412, the manager terminal 3 transmits a recording end instruction to the information management device 20. In the pile driver 1, the instruction receiving unit 212 receives the recording end instruction and ends recording of the construction data.

[0048] As shown in Fig. 4, the main box 2 of the pile driver 1 acquires the construction data measured by the pile driver 1, and the report is created in the main box 2, rather than the manager terminal 3 and the viewer terminal 4 creating the report. Each terminal receives the report directly from the main box 2. Therefore, unlike the case where the construction data is stored in a server such as a cloud or the manager terminal 3 and the report is created, it is possible to reduce the possibility of tampering with the construction data and the report. In addition, since the manager terminal 3 does not acquire the original data of the construction data, it is also possible to reduce the possibility of tampering with the construction data itself.

[0049] The administrator terminal 3 and the viewer terminal 4 may have a function of making the scene in which the construction data and the form are displayed into a print screen or a portable document format (PDF). The function may be executable on the management application accessed by a URL as one of the functions of the application, or the permission may be set so that the print screen function or the PDF conversion function of the terminal can be executed on the screen of the management application.

[0050] 4, the operations of the manager terminal 3 and the viewer terminal 4 are described as steps, but the instructions from the manager terminal 3 and the viewer terminal 4 do not necessarily have to be processed in the order of the step numbers. That is, if there is an instruction from the manager terminal 3 or the viewer terminal 4, the information management device 20 may operate independently in response to the instruction. The manager terminal 3 and the viewer terminal 4 can receive the construction data and the report at any time, such as during excavation, when excavation is completed, or while milk is being poured. Furthermore, the form creation unit 214 of the information management device 20 may automatically create a form as soon as the construction is completed. In this way, since it is possible to log in to the information management device 20 from a terminal other than the administrator terminal 3, such as the viewer terminal 4, it is possible to prevent data tampering after the construction is completed by a person other than the administrator checking the data during the construction.

[0051] Next, a second operation example of the information management system according to this embodiment will be described with reference to the sequence diagram of FIG. The second operation example shown in Fig. 5 is a sequence diagram regarding data transmission and reception between the administrator terminal 3 and multiple pile drivers (pile driver 1A and pile driver 1B) from the start of construction to the creation of reports. If there are multiple pile drivers 1, each is set with its own SSID, and the screen displayed on the administrator terminal 3 displays one SSID from the multiple SSIDs so that it can be selected. Therefore, the user of the administrator terminal 3 simply selects the SSID of the pile driver 1 he or she wishes to connect to and enters the password.

[0052] First, a wireless connection is established between the manager terminal 3 and the pile driver 1A (steps S401 and S402). After that, the manager terminal 3 transmits an instruction to the pile driver 1A to start recording construction data, and the data acquisition unit 211 in the pile driver 1A starts acquiring construction data from various sensors (steps S403 and S404).

[0053] Next, the administrator terminal 3 requests a wireless connection with the pile driver 1B (step S401). Specifically, the administrator terminal 3 selects the SSID set by the pile driver 1B to which the administrator terminal 3 wishes to wirelessly connect, and inputs a password.

[0054] In step S501, when the administrator terminal 3 transmits a connection request to a pile driver 1B other than the currently connected pile driver 1A, the wireless connection between the administrator terminal 3 and the pile driver 1A is disconnected. The wireless connection can be disconnected by any common method, for example, the administrator terminal 3 transmits a signal (Deauthentication) to the pile driver 1A requesting that the wireless connection be disconnected, and the connection control unit 215 in the pile driver 1A disconnects the connection.

[0055] In the pile driver 1B, the connection control unit 215 authenticates the connection request from the administrator terminal 3. In this case, the authentication is successful, and the connection control unit 215 establishes a wireless connection between the administrator terminal 3 and the pile driver 1B (step S402). After that, the administrator terminal 3 transmits a recording start instruction to the pile driver 1B, and the data acquisition unit 211 in the pile driver 1B starts acquiring the construction data (steps S403 and S404).

[0056] The manager terminal 3 again requests a wireless connection with the pile driver 1A (step S401). Because the manager terminal 3 has sent a connection request to another pile driver 1A, the connection control unit 215 in the pile driver 1B releases the wireless connection with the manager terminal 3 (step S501). After that, a wireless connection is established between the manager terminal 3 and the pile driver 1A (step S402).

[0057] When the construction of the piles is completed, the manager terminal 3 transmits an instruction to the pile driver 1A to create a form, and receives the form created by the pile driver 1A (steps S409 to S411). After that, the manager terminal 3 transmits an instruction to end recording to the pile driver 1A (step S412).

[0058] The manager terminal 3 also causes the pile driver 1B to execute the same form creation process (steps S409 to S412).

[0059] Although not shown in FIG. 5, the manager terminal 3 can also transmit a request to check the construction status to the pile driver 1 connected wirelessly, and acquire construction data during construction.

[0060] In this way, the manager terminal 3 can acquire construction data and reports acquired by multiple pile drivers 1 even from a location far from the pile drivers 1, such as a station, by switching the wireless connection destination for multiple pile drivers 1, and data can be collected efficiently. Therefore, since the manager does not need to go to the pile driver 1 and acquire the construction data from the main box via USB (Universal Serial Bus), this leads to a reduction in the time required for construction management such as creating reports.

[0061] Next, a third operation example of the information management system including the information management device 20 according to this embodiment will be described with reference to the sequence diagram of FIG. FIG. 6 is a sequence diagram regarding data transmission and reception between a plurality of manager terminals 3 (manager terminal 3A and manager terminal 3B) and the pile driver 1 from the start of construction to the creation of a document.

[0062] Here, first, the manager terminal 3A establishes a wireless connection with the pile driver 1, and the pile driver 1 starts acquiring construction data in response to an instruction from the manager terminal 3A to start recording the construction data (steps S401 to S404).

[0063] Next, the manager terminal 3B establishes a wireless connection with the pile driver 1 (steps S401 and S402). The wireless communication device 25 of the pile driver 1 can simultaneously connect multiple terminals like a general wireless LAN router, so multiple manager terminals 3 and multiple viewer terminals 4 (not shown) may be connected simultaneously within the range allowed by the wireless communication device 25.

[0064] Next, the manager terminal 3A and the manager terminal 3B transmit a request to confirm the construction status (step S407).

[0065] In the pile driver 1, the data conversion unit 213 converts the construction data acquired up to the time when the request to check the construction status was received. In the pile driver 1, the wireless communication unit 216 transmits the converted construction data to the manager terminal 3A and the manager terminal 3B (step S408).

[0066] The manager terminal 3A transmits an instruction to create a form, and the form creation unit 214 in the pile driver 1 creates a form based on the construction data and transmits it to the manager terminal 3A (steps S409 to S411).

[0067] Similarly, the manager terminal 3B transmits an instruction to create a form, and the form creation unit 214 in the pile driver 1 creates a form based on the construction data and transmits it to the manager terminal 3B (steps S409 to S411).

[0068] The manager terminal 3A transmits an instruction to end recording of the construction data to the pile driver 1 (step S412).

[0069] As shown in Figure 6, instructions to start and end construction may be set only for a specific manager terminal 3, or instructions to start and end construction may be set for all manager terminals 3 connected to the pile driver 1.

[0070] Although the case where one pile driver 1 constructs one pile has been described in FIG. 4 to FIG. 6, one pile driver 1 may construct multiple piles in succession. For example, when the pile driver 1 completes the construction of one pile, the construction data of the pile is stored in the storage unit 22, so that even if the pile driver 1 is constructing another pile, the manager terminal 3 can wirelessly connect to the pile driver 1 and obtain the construction data of the already constructed pile from the storage unit 22. Therefore, if there is an instruction to create a form from the manager terminal 3, the form creation unit 214 can create a form from the construction data. Therefore, the manager can create forms for multiple piles at once without having to send an instruction to create a form every time the construction of one pile is completed, and therefore construction can be managed efficiently.

[0071] The manager terminal 3 or the viewer terminal 4 may notify the construction status by voice, buzzer or other alarm, push notification, etc., when a specific event occurs, such as reaching the support layer, completion of excavation, completion of filling with milk or the like, and completion of construction. This allows the manager or viewer to check the manager terminal 3 or the viewer terminal 4 when a specific event occurs without having to constantly worry about the construction status, thereby achieving efficient management.

[0072] Furthermore, the construction data and reports acquired by the manager terminal 3 or the viewer terminal 4 shown in Figures 4 to 6 may be transmitted from the terminal to a cloud server of a management company or the like via a mobile communication network such as 4G or 5G.

[0073] Next, an example of a form created by the pile driver 1 will be described with reference to Figs. The document 70 shown in Figure 7 indicates bibliographic information 71 such as the name of the construction site, the construction date, and the pile number, a columnar diagram 72 showing information on the stratum according to depth, an integrated current value 73 up to the current excavation depth, an N value 74 extracted from the columnar diagram and input in advance, excavation shape information 75 showing the partial shape of the excavation that has been completed from the start of excavation to the present, and excavation plan shape information 76 showing the final shape to be excavated.

[0074] 7, the report 80 shown in Fig. 8 shows time series data of instantaneous current value 82 according to depth 81 and time series data of drilling water 83. By referring to the time series data shown in Fig. 8, the manager having the manager terminal 3 and the viewer having the viewer terminal 4 can determine at what stage drilling water, etc. is being injected in chronological order.

[0075] According to the embodiment described above, the pile driver creates a form for each pile driver in the main box using an information management device included in the main box. The manager terminal or the viewer communicates with the main box equipped with a wireless communication device such as Wi-Fi to wirelessly receive the construction data and the form directly from the pile driver without going through a server such as a cloud. In this way, by wirelessly communicating between the information management device and the manager terminal, the manager can start recording construction data and manage the data without approaching the pile driver or other heavy machinery on which the management device is mounted. This improves safety in on-site management and makes construction management more efficient.

[0076] In addition, multiple administrators and viewers who know the SSID and password can view the construction data and reports at any time, and since the data from the pile driver 1 is under the supervision of multiple people, the possibility of tampering with the numbers and graphs in the construction data and reports is reduced. The reports created by the information management device in the main box are created in report format, so the reports can be received from the pile driver and submitted as reports as is, reducing the burden on administrators. Furthermore, because the report is wirelessly transmitted from the information management device to the manager's terminal, the user does not need to extract the construction data from the information management device and create the report, improving user convenience. Also, because the report is created by the information management device, the manager does not need to create the report based on the construction data, and data tampering can be suppressed.

[0077] The instructions shown in the processing procedures shown in the above-mentioned embodiments can be executed based on a program, which is software. A general-purpose computer system can store this program in a recording medium in advance and obtain the same effect as that of the above-mentioned identification device by reading the stored program. Furthermore, the recording medium in this embodiment is not limited to a medium independent of a computer or an embedded system, but also includes a recording medium in which a program transmitted via a LAN, the Internet, or the like is downloaded and stored or temporarily stored.
