The pile driver 11 equipped with the construction management device 41 formed in this way removes the auger 28 from the leader 15 and divides the leader 15 in order to make the mass and length dimension suitable for transportation, for example, Upper reader 24 may be separated from intermediate reader 23 and shipped separately. At this time, the second relay device 47 is in a state in which the second upper communication line 45c is removed from each of the upper communication ports 46b and 47a, that is, in a state in which the network connection between the first relay device 46 and the second relay device 47 is released. Then, it is detached from the leader 15 together with the auger 28 and loaded on the carrier of the transport truck together with the auger 28 for transportation. In addition, the first relay device 46 is operated in a state in which the first upper communication line 45b is removed from each of the upper communication ports 49c and 46a, that is, in a state in which the network connection between the switching hub 49 and the first relay device 46 is released. By releasing the connection between the second member 23b and the upper first member 24a, the intermediate leader 23 is removed together with the upper leader 24, and together with the upper leader 24, it is loaded on the bed of a transport truck and transported.

The removed first higher-order communication line 45b and second higher-order communication line 45c can be carried in a storage case. It can also be transported by fixing it to the upper revolving body 13 using a binding band or the like in a ring-shaped bundle.

After assembling various parts such as the reader 15 and the auger 28 on site, the first upper communication line 45b is connected to each higher communication port 49c, 46a, and the second higher communication line 45c is connected to each higher communication port 46b, 47a. By connecting, the network that was temporarily disconnected during transportation is restored, and the power supply of the construction management device 41 can be activated.

When the construction management device 41 is powered on, the control device 43 executes the construction management program, and a login screen is displayed on the display 44 . Here, construction data can be acquired by logging into the system using the worker ID and setting construction conditions according to the purpose from the menu screen. Further, each relay device 46 to 48 starts transmission of a signal from the detection means 42 to the control device 43, and determines whether or not an alarm should be issued based on the state of the network connection, the detection means 42, etc. device monitoring mode.

As described above, since the wiring work of the device communication line 50 is omitted when the reader 15 and the auger 28 are disassembled and assembled, troubles caused by the wiring work of the device communication line 50 can be prevented. Vibration during disassembly and assembly of 15 may cause the detection means 42 , for example, the depth sensor 54 to malfunction. In such a case, the device monitoring unit 46c of the first relay device 46 outputs a signal indicating that the depth sensor 54 is in a failure state. Causes a message to be displayed for failure conditions. As a result, the faulty depth sensor 54 is removed and replaced with a new one, and the cause of the problem is investigated separately. Also, the signal from the device monitoring unit 46c is treated as log data in which the serial number and revision that can identify the depth sensor 54, error content, and failure occurrence time are associated with each other.

Next, processing for recording construction data and log data in the control device 43 will be specifically described with reference to FIG. First, for example, along with construction of the ready-made pile construction method, a signal from the detection means 42 is taken into the control device 43 via the input/output section 43g, as shown in FIG. 3(A). Then, construction data is created by executing the construction management program by arithmetic processing of the CPU, and displayed on the display 44 in a predetermined format. As a result, it is possible to objectively obtain knowledge about the construction status such as the construction position and construction depth of piles and the operator's operation history, that is, the input history of information related to construction. On the other hand, the data processing unit 43a transfers the construction data to the USB memory 52 in a predetermined format. Here, the control device 43 acquires a backup of the construction data by recording the construction data in the internal storage device 43f as the construction data is transferred by the data processing unit 43a. Also, as shown in FIG. 3B, construction data can be backed up in an external storage device 43h, which is an external recording medium, instead of the internal storage device 43f. In this case, the external storage device 43h and the data processing unit 43a are connected for communication. Further, log data is recorded in the internal storage device 43f or the external storage device 43h together with the recording of construction data by the data processing unit 43a. The USB memory 52 recording the construction data is brought into the management office by the field worker, and the data is transferred to a user terminal (not shown) such as a computer so that the construction data can be saved and managed.

By the way, when a question arises in the construction data or when a problem arises in the substance of the construction during or after the construction, it is necessary to verify the construction. Therefore, regarding the construction status, for example, when there is a doubt about the construction depth at a certain pile construction position, the site manager activates the power supply of the construction management device 41, and from the login screen displayed on the display 44, the manager Login to the system by ID. The administrator ID is identification information set to identify a person who is given access authority or editing authority to data recorded in the internal storage device 43f or the external storage device 43h. It is distinguished from the worker ID that is not used. If the determination unit 43b checks the administrator ID and the input ID and determines that they match, it causes the display 44 to display a menu screen for the administrator.

Next, after confirming that an empty USB memory 52 in which data is not recorded is attached to the USB interface 43e, a copy of construction data and log data is transferred to the USB memory 52 by pressing the touch panel. As a result, the site manager brings the USB memory 52 recording the construction data and log data to the management office and transfers the data via the USB interface provided in the user terminal so that the construction status can be verified. Become. Log data, by its nature, holds various information about the operation and devices of the pile driver 11. Therefore, it is stored in a database (not shown) on the network, and information can be registered and updated. done. As a result, a system is constructed in which various types of information can be inquired in a form suitable for the purpose by inquiring from the user terminal. An example of such a system is a query system that can query information regarding maintenance (repair, replacement, etc.) of the detection means 42 .

The management office compares the construction data in question with the construction data prepared for verification to confirm the identity of the construction data. If these data are the same, the knowledge about the construction situation that has already been obtained will be considered while referring to the log data. Specifically, the change in the signal of the depth sensor 54 during the construction period is read from the log data, and it is confirmed whether the waveform shown in the graph is normal. Here, if it is found that the measured value by the depth sensor 54 has an error in comparison with the actual object, the cause of the error will be investigated. As a result of detailed verification, if the depth sensor 54 is to be replaced with a new one, for example, log in to the inquiry system from the user terminal, grasp the serial number and revision of the substitute part on the inquiry screen, and check the delivery date. Preparations necessary for arranging parts, such as confirmation, are made.

In this manner, the data processing unit 43a of the control device 43 transfers the construction data to the USB memory 52, and simultaneously records the construction data in the internal storage device 43f or the external storage device 43h to obtain a backup. Therefore, it is possible to avoid a situation in which the use of construction data is hindered with a simple configuration. In addition, since the internal storage device 43f or the external storage device 43h records temporal changes in the signal from the detection means 42 as log data, even if there is doubt about the construction status, the construction data and the log data can be , it is possible to quickly and accurately investigate the cause and improve the reliability of construction. Furthermore, if, for example, an administrator ID is set in order to identify the user, unauthorized access by a third party can be prevented and information security can be strengthened. In addition, since the log data is stored in the database, it becomes possible to easily acquire information regarding maintenance of the detection means 42, and the maintenance and management of the construction management device 41 can be ensured.

In addition, since the construction management apparatus 41 is provided with a device monitoring mode, which is an operation mode for monitoring the state of the network including the detecting means 42, it is possible to easily identify the location and cause of the failure. Furthermore, since the state of the construction management device 41 is monitored based on the identification information and diagnostic information of the detection means 42 by IO-Link communication, the disconnection and restoration of the network connection are repeated each time the pile driver 11 moves to the site. However, construction can be carried out in a stable state.

This is performed by alternately repeating a process of pushing the excavation bucket and the bottom-enlarged bucket 79 into the ground while rotating and a process of lifting the excavation bucket and the bottom-enlarged bucket 79 to discharge the excavated earth and sand.

Next, the construction management device of the present invention applied to the earth drill 71 will be described with reference to FIGS. 2 to 4. FIG. As shown in the block diagram of FIG. 2, this construction management device is configured in common with the construction management device 41 of the pile driver 11. In the control device 43, a construction management program for executing the earth drilling method is executed. be. Also, in order to correspond to the form of the earth drill 71, the mounting positions of the detection means 42 and the relay devices 46 to 48 are different from the mounting positions of the pile driver 11, but the principle of operation by the control device 43 is the same. , and the processing for recording the construction data and log data can also be performed with similar control, as shown in FIG.

4, the first relay device 46 is attached to the side surface of the lower boom 72c, specifically, the base end of the front frame 76, and the second relay device 47 is attached to the Kelly drive 78, as shown in FIG. , the third relay device 48 is screwed into the equipment chamber 20 of the upper rotating body 13 via a mounting seat.

As an example of the detection means 42, the second relay device 47 is connected to a device communication port 47c via a rotation sensor communication line 50c with a rotation sensor 56 that measures the number of rotations of the Kelly bar 75. FIG. The rotation sensor 56 detects the gear teeth of the output mechanism 85 with a proximity sensor and counts the pulse signals. A signal detected by the rotation sensor 56 is transmitted to the control device 43 via the second relay device 47, the first relay device 46, and the switching hub 49, and the cumulative number of revolutions and the rotational speed are calculated based on the cumulative count. .

The earth drill 71 equipped with the construction management device 41 formed in this way is assembled with the Kelly drive 78, Kelly bar 75 and wide bottom bucket 79 at the front part of the base machine 14 in order to make the mass and length dimension suitable for transportation. In some cases, the boom 72 is divided into a plurality of parts and transported separately. At this time, the second relay device 47 is in a state in which the second upper communication line 45c is removed from each of the upper communication ports 46b and 47a, that is, in a state in which the network connection between the first relay device 46 and the second relay device 47 is released. , it is removed together with the Kelly drive 78 from the front frame 76 and the holding cylinder 77, and loaded on the bed of a transport truck together with the Kelly drive 78 for transportation. Also, the first relay device 46, in a state in which the first upper communication line 45b is removed from each of the upper communication ports 49c, 46a, that is, in a state in which the network connection between the switching hub 49 and the first relay device 46 is released, By disconnecting the boom 72a, the intermediate boom 72b, and the lower boom 72c from each other and disconnecting the connection between the upper rotating body 13 and the lower boom 72c, the lower boom 72c is removed from the upper rotating body 13 integrally with the lower boom. Together with 72c, it is loaded on the platform of a transport truck and transported.

After assembling various parts such as the boom 72 and Kelly drive 78 at the site, the first upper communication line 45b is connected to each higher communication port 49c, 46a, and the second higher communication line 45c is connected to each higher communication port 46b, 47a. By connecting to , the network that was once disconnected during transportation is restored, and the power supply of the construction management device 41 can be activated.

When the construction management device 41 is powered on, the control device 43 executes the construction management program, and a login screen is displayed on the display 44 . Here, construction data can be acquired by logging into the system using the worker ID and setting construction conditions according to the purpose from the menu screen. Further, each relay device 46 to 48 starts transmission of a signal from the detection means 42 to the control device 43, and determines whether or not an alarm should be issued based on the state of the network connection, the detection means 42, etc. device monitoring mode.

As described above, since the wiring work of the device communication line 50 is omitted when disassembling and assembling the boom 72 and the Kelly drive 78, troubles caused by the wiring work of the device communication line 50 are prevented. Vibration during disassembly and assembly of the Kelly drive 78 may cause the detection means 42 , for example, the rotation sensor 56 to malfunction. In such a case, the device monitoring unit 47b of the second relay device 47 outputs a signal indicating that the rotation sensor 56 is in a failure state. Causes a message to be displayed for failure conditions. As a result, the malfunctioning rotation sensor 56 is removed and replaced with a new one, and the cause of the malfunction is investigated separately. Further, the signal from the device monitoring unit 47b is treated as log data in which the serial number and revision that can identify the rotation sensor 56, the content of the error, and the time of occurrence of the failure are associated with each other.

By applying the present invention to the earth drill 71 in this manner, the same effects as in the case of applying the present invention to the above-described pile driver 11 can be obtained. Above all, construction can be carried out in a stable state even when the network connection is repeatedly disconnected and restored every time the machine moves to the site, which is characteristic of these construction machines.

In addition, it is possible to acquire construction data in various construction methods, not limited to the ready-made pile construction method, the cast-in-place pile construction method, the ground improvement construction method, or the earth drill construction method. Furthermore, although a USB memory has been described as an example of a portable recording medium used for exchanging data, any recording medium having a data holding function such as a memory card can be applied, and the type of recorded data can be an image. It may be data. Also, as the ID for identifying the user, various IDs can be set according to the authority. In particular, except for the ID assigned to the administrator, it is possible to deter fraudulent acts such as falsification and falsification of data by a third party by not giving editing authority including deletion of data.

Also, at the construction site, the number and installation positions of the relay devices are arbitrary as long as they can be safely connected to the network without interfering with the operation of the aircraft and the attachment and detachment of various components. Furthermore, various detection means can be applied according to the purpose of construction management. The application torque is calculated based on the current detected by this current sensor. Also, although PROFINET is used as an industrial Ethernet for the network, it is not limited to this, and for example, EtherCAT (registered trademark) can be used. Furthermore, it is possible to configure a network in combination with CAN communication or the like.
