Furthermore, among the components in the following embodiments, components not recited in independent claims will be described as optional components.

[0013] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0014] (Embodiment) First, the construction management system of the present disclosure will be described using Fig. 1. Fig. 1 is a schematic diagram of a construction management system 2 according to the present embodiment. The construction management system 2 shown in Fig. 1 is a system for a building 1 equipped with equipment 11 that requires predetermined tightening by fastening parts, and is a system comprising a terminal device 3, a tool 4, and a management device 6. Fig. 1 is a schematic diagram showing a scene in which a worker uses the construction management system 2 to tighten a fastening part (e.g., a screw) to an electric wire fastening part (e.g., a terminal block in a distribution board) provided in the equipment 11.

[0015] First, the worker reads the two-dimensional code 12 assigned to the equipment 11 to be tightened using the terminal device 3. The terminal device 3 transmits the information read from the two-dimensional code 12 to the tool 4. The tool 4 tightens the fastening part to the equipment 11 based on the received information. The tool 4 transmits information obtained from the actual tightening work to the management device 6 via the network 5. The management device 6 manages the received information. According to this construction management system 2, the construction results are automatically recorded.

[0016] [Configuration] The configuration of the construction management system 2 according to the embodiment will be described below. Fig. 2 is a block diagram showing the functional configuration of the construction management system 2 according to the embodiment. The present disclosure is configured by a building 1 and a construction management system 2.

[0017] The building 1 is a structure equipped with facilities 11, and may be, for example, a factory building or a general residence. The building 1 may also have multiple facilities 11.

[0018] The equipment 11 is equipment that requires a predetermined tightening by a fastening part, such as an electric wire fastening part that is an electrical connection part provided in a distribution board. Specifically, the equipment 11 is a terminal block provided in the distribution board. The fastening part is, for example, a screw, a bolt, a nut, or the like.

[0019] Each piece of equipment 11 has a two-dimensional code 12 assigned to it. For example, as shown in Fig. 1 , a sticker on which the two-dimensional code 12 is printed is attached to the equipment 11. The two-dimensional code 12 is, for example, a QR code (registered trademark).

[0020] Returning to the explanation in Fig. 2, work information for the equipment 11 is embedded in the two-dimensional code 12. The work information is information that includes at least set tightening torque information and identification information of the equipment 11. The set tightening torque information is information that indicates the amount of torque that is applied to the fastening part and is required for a predetermined tightening of the equipment 11. The identification information is information that includes an identification number assigned to the equipment 11 (distribution board).

[0021] The construction management system 2 is a system for a building 1 equipped with equipment 11 that requires predetermined tightening by fastening parts.

[0022] The construction management system 2 includes a terminal device 3 , a tool 4 , and a management device 6 .

[0023] The terminal device 3 is a device used by a worker who uses the tool 4, and is, for example, an information terminal such as a smartphone or a tablet.

[0024] The terminal device 3 includes a reading unit 31 , a control unit 32 , and a transmission unit 33 .

[0025] The reading unit 31 is a camera or the like that reads the two-dimensional code 12 .

[0026] The control unit 32 acquires the work information embedded in the two-dimensional code 12 read by the reading unit 31. The control unit 32 is realized by, for example, a microcomputer or a processor. The functions of the control unit 32 are realized, for example, by the microcomputer or processor constituting the control unit 32 executing a computer program stored in memory.

[0027] The transmitter 33 is a communication circuit for the terminal device 3 to communicate with the tool 4. The transmitter 33 transmits the work information acquired by the control unit 32 to the tool 4. The transmitter 33 may be a communication circuit for communicating through a wide area communication network such as the Internet, or may be a communication circuit for communicating through a local communication network. The transmitter 33 may perform wired communication or wireless communication. There are no particular limitations on the standard of communication performed by the transmitter 33.

[0028] The tool 4 is a tool for tightening fastening components to the equipment 11, and is, for example, an impact driver. The tool 4 will be described with reference to Fig. 3. Fig. 3 is an external view of the tool 4.

[0029] 3 , the tool 4 includes a body 40. The body 40 includes a trunk portion 41, a grip portion 42, and an attachment portion 43.

[0030] The body 41 is formed in a cylindrical shape. The grip 42 protrudes in one direction from a part of the circumferential surface of the body 41. The attachment 43 is formed in a flat rectangular parallelepiped shape. The body 41 and the attachment 43 are connected by the grip 42.

[0031] The body portion 41 accommodates at least some of the components of the fastening portion 46 shown in Fig. 2. An output shaft 461, which is a component of the fastening portion 46, protrudes from one axial end face of the body portion 41.

[0032] The grip portion 42 is a portion that an operator grips when using the tool 4 to tighten a fastening part. The grip portion 42 is also provided with a trigger switch 421 that allows the operator to operate the tool 4. The trigger switch 421 is a switch that controls the on / off operation of the tightening portion 46. The trigger switch 421 has an initial position and an on position, and the tightening portion 46 operates when the operator pushes or pulls the trigger switch 421 to the on position. The trigger switch 421 can also adjust the rotation speed of the tightening portion 46 depending on the amount of retraction (amount of operation).

[0033] A removable battery 431 is attached to the mounting portion 43 on one side opposite to the side connected to the grip portion 42. The battery 431 is realized by, for example, a lithium ion battery, and supplies power to each component of the tool 4 shown in FIG.

[0034] Returning to the explanation of FIG. 2 , the tool 4 includes a receiving unit 44 , a control unit 45 , a tightening unit 46 , and a transmitting unit 47 .

[0035] The receiving unit 44 is a communication circuit for the tool 4 to communicate with the terminal device 3. The receiving unit 44 receives work information transmitted by the transmitting unit 33 of the terminal device 3. The receiving unit 44 may be a communication circuit for communicating through a wide area communication network such as the Internet, or may be a communication circuit for communicating through a local communication network. The standard of communication performed by the receiving unit 44 is not particularly limited.

[0036] The control unit 45 controls the operation of the tightening unit 46 (i.e., the tightening operation) based on the work information received by the receiving unit 44. Specifically, the control unit 45 controls the operation of the motor 462, the impact mechanism 463, and other components of the tightening unit 46 so that the torque amount included in the tightening set torque information is applied to the fastening part.

[0037] The control unit 45 also has a torque estimation function that estimates the amount of torque applied to the fastening part. For example, the control unit 45 estimates the amount of torque applied to the fastening part based on the rotation speed and rotation time of the motor 462. When the estimated torque amount (fastening torque) reaches the torque amount (set torque) included in the set fastening torque information, the control unit 45 stops the operation of the motor 462, the impact mechanism 463, and other components of the fastening unit 46.

[0038] The control unit 45 also determines whether the tightening of the fastening parts is normal or abnormal (i.e., whether there is a tightening defect) based on the rotation angle of the hammer of the impact mechanism 463, which will be described later. Normal tightening of the fastening parts means, for example, that the bolt or the like is tightened along the direction of the screw hole. Abnormal tightening of the fastening parts means, for example, that the bolt or the like is tightened obliquely relative to the screw hole (galling).

[0039] The control unit 45 also generates, as transmission information, torque information obtained when the tool 4 is used based on the work information for the equipment 11 and the work information received by the receiving unit 44. In other words, the transmission information is information in which the torque information and the work information are linked. The torque information includes the amount of torque estimated by the control unit 45 and the determination result of whether or not there is a tightening defect. The torque information may also include tool information indicating the identification number of the tool 4, or may also include worker information indicating the worker who used the tool 4.

[0040] The control unit 45 also includes an acquisition unit 451. The acquisition unit 451 acquires information (motor information) about the motor 462, such as the rotation speed and rotation time of the motor 462, from an encoder or the like, which is a component of the tightening unit 46. The control unit 45 estimates the amount of torque applied to the fastening part based on the information about the motor 462 acquired by the acquisition unit 451. The acquisition unit 451 also acquires motor information, such as the rotation angle of the hammer of the impact mechanism 463, from an encoder or the like, which is a component of the tightening unit 46. The control unit 45 determines whether or not there is a tightening defect based on the rotation angle of the hammer acquired by the acquisition unit 451.

[0041] The control unit 45 is realized by, for example, a microcomputer or a processor, etc. The functions of the control unit 45 are realized, for example, by the microcomputer or processor constituting the control unit 45 executing a computer program stored in a memory, etc.

[0042] The tightening unit 46 has an output shaft 461, a motor 462, an impact mechanism 463, a reduction mechanism (not shown), a drive shaft (not shown), a socket (not shown), an encoder (not shown), etc. The tightening unit 46 rotates and drives the socket (i.e., the tool tip) using power from the motor 462 to tighten the fastening component.

[0043] The speed reduction mechanism of the tightening unit 46 transmits the rotational force of the rotary shaft of the motor 462 to the drive shaft. The speed reduction mechanism is, for example, a planetary gear mechanism, and converts the rotational speed and torque of the rotary shaft of the motor 462 into the rotational speed and torque required for the tightening operation. The output shaft 461 receives the rotation of the drive shaft and transmits it to the socket. The output shaft 461 rotates around a rotation axis along its protruding direction. In other words, the tightening unit 46 drives the output shaft 461 to rotate the output shaft 461 around the rotation axis.

[0044] A cylindrical socket for rotating a fastening part (e.g., a bolt or a nut) is removably attached to the output shaft 461. The socket rotates together with the output shaft 461 about the rotation axis. The size of the socket attached to the output shaft 461 is appropriately selected by the operator according to the size of the fastening part. With this configuration, when the tightening unit 46 operates, the output shaft 461 rotates, and the socket rotates together with the output shaft 461. At this time, if the socket is fitted with the fastening part, the fastening part rotates together with the socket, and the tool 4 tightens the fastening part.

[0045] Also, a socket anvil can be attached to the output shaft 461 instead of the socket. In such a case, a bit (for example, a driver bit or a drill bit) can be attached to the tool 4 via the socket anvil.

[0046] The impact mechanism 463 is driven by the power of the motor 462. The impact mechanism 463 includes, for example, a hammer rotatably supported by the drive shaft, and an anvil (striking portion) provided at the rear end of the output shaft 461. The hammer strikes the anvil in response to the rotation of the drive shaft.

[0047] When the tightening torque exceeds a predetermined level (for example, when the tightening torque reaches 80% of the set torque), the impact mechanism 463 applies an impact in the rotational direction to the output shaft 461. This enables the tool 4 to apply a larger tightening torque to the fastening part.

[0048] In the present embodiment, it is not essential that the impact mechanism 463 and the socket be included in the components of the fastening portion 46. The impact mechanism 463 and the socket do not necessarily have to be included in the components of the fastening portion 46.

[0049] The transmitting unit 47 is a communication circuit for the tool 4 to communicate with the outside (the management device 6 in FIG. 2 ). The transmitting unit 47 transmits the transmission information generated by the control unit 45 to the management device 6. The transmitting unit 47 transmits the transmission information to the management device 6 via the network 5.

[0050] The network 5 is, for example, a wide area communication network such as the Internet.

[0051] The management device 6 is a server device that manages the transmission information transmitted by the transmission unit 47. The management device 6 includes a receiving unit 61, a storage unit 62, a display unit 63, and a control unit 64.

[0052] The receiving unit 61 is a communication circuit for the management device 6 to communicate with the tool 4. The receiving unit 61 receives transmission information transmitted by the transmitting unit 47 of the tool 4. The receiving unit 61 receives the transmission information from the tool 4 via the network 5.

[0053] The storage unit 62 is a storage device that stores transmission information, computer programs executed by the control unit 64, etc. The storage unit 62 is realized by, for example, a memory.

[0054] The display unit 63 displays the construction results and the like output by the determination unit 642, which will be described later. The display unit 63 is realized by, for example, a liquid crystal display or the like.

[0055] The control unit 64 controls the entire management device 6. The control unit 64 is realized by, for example, a microcomputer or a processor. The functions of the control unit 64 are realized, for example, by the microcomputer or processor constituting the control unit 64 executing a computer program stored in the storage unit 62.

[0056] The control unit 64 includes a time acquisition unit 641 and a determination unit 642 .

[0057] The time acquisition unit 641 acquires a work time indicating the time when the fastening part was tightened by the tool 4. For example, the time acquisition unit 641 acquires, as the work time, the time when the receiving unit 61 acquired the transmission information. The time acquisition unit 641 associates the acquired work time with the transmission information.

[0058] The determination unit 642 determines whether the predetermined tightening has been accurately performed by the tool 4 based on the set tightening torque information and torque information included in the transmission information received by the receiving unit 61. The determination unit 642 determines, for example, whether the tightening torque estimated by the control unit 45 of the tool 4 reaches the set torque included in the set tightening torque information, or whether the fastening part has been tightened in the correct direction. The determination unit 642 outputs a construction result that summarizes the above-mentioned determination results.

[0059] The tool 4 may have the reading unit 31. In this case, the worker uses the tool 4 to read the two-dimensional code 12 assigned to the equipment 11.

[0060] Furthermore, the tool 4 may have a time acquisition unit 641. In this case, the time acquisition unit 641 of the tool 4 acquires the work time indicating the time when the fastening part was tightened, and the control unit 45 of the tool 4 generates transmission information in which the torque information, the identification information, and the work time are linked.

[0061] Furthermore, the management device 6 may transmit the construction result determined by the determination unit 642 to another terminal device. For example, the management device 6 may transmit the construction result to the terminal device 3 carried by the worker. This makes it easier for the worker to check the construction result.

[0062] [Operation of the Construction Management System] The flow in which a worker tightens a fastening component using a tool 4 and the construction results are automatically recorded will be described with reference to Fig. 4. Fig. 4 is a sequence diagram showing the operation of the construction management system 2 according to the embodiment.

[0063] First, under the operation of a worker, the reading unit 31 of the terminal device 3 reads the two-dimensional code 12, and the control unit 32 of the terminal device 3 acquires the work information embedded in the two-dimensional code 12 (step S1).

[0064] The transmitter 33 of the terminal device 3 transmits the work information acquired by the controller 32 in step S1 to the tool 4 (step S2). The receiver 44 of the tool 4 receives the work information.

[0065] The tool 4 performs the tightening operation (i.e., the operation of the tightening unit 46) under the operation of the worker based on the work information received by the receiving unit 44 (step S3).

[0066] The transmitting unit 47 of the tool 4 transmits the transmission information generated by the control unit 45 of the tool 4 to the management device 6 (step S4). The receiving unit 61 of the management device 6 receives the transmission information.

[0067] The determination unit 642 of the management device 6 performs a determination process (i.e., determines whether the predetermined tightening has been accurately performed by the tool 4) based on the transmission information received by the receiving unit 61 (step S5). The determination unit 642 outputs a construction result that summarizes the results of the determination made in step S5.

[0068] The control unit 64 of the management device 6 displays the construction results output by the determination unit 642 on the display unit 63 (step S6).

[0069] Note that the transmission of the work information from the terminal device 3 to the tool 4 in step S2 may be performed, for example, via the management device 6. In such a case, the management device 6 can centrally manage the work information, which is information related to the equipment 11. Furthermore, when a user or the like modifies the work information on the management device 6, the tool 4 can acquire the work information reflecting the modification or the like.

[0070] Furthermore, the transmission of the transmission information from the tool 4 to the management device 6 in step S4 may be performed, for example, via the terminal device 3. In such a case, the terminal device 3 temporarily stores the transmission information. This allows the transmission information to be temporarily stored even when the radio wave conditions of the Internet line are poor inside the building 1 where the equipment 11 is installed and the terminal device 3 is unable to transmit the transmission information to the management device 6. Furthermore, when the radio wave conditions of the Internet line improve as a result of the worker moving outside the building 1 together with the terminal device 3, the terminal device 3 can retransmit the transmission information to the management device 6.

[0071] Next, among the steps shown in FIG. 4, steps S3, S5, and S6 will be described in detail with reference to FIGS.

[0072] FIG. 5 is a flowchart showing the detailed operation of step S3 shown in FIG.

[0073] The control unit 45 controls the tightening operation based on the work information received by the receiving unit 44 (step S11).

[0074] The acquisition unit 451 acquires motor information and the rotation angle of the hammer from an encoder that is a component of the tightening unit 46 (step S12).

[0075] The control unit 45 estimates the tightening torque, which indicates the amount of torque applied to the fastening component, based on the motor information acquired by the acquisition unit 451 in step S12 (step S13).

[0076] The control unit 45 determines whether or not there is a tightening defect in the fastening part based on the rotation angle of the hammer acquired by the acquisition unit 451 in step S12 (step S14).

[0077] The control unit 45 generates torque information including the tightening torque estimated in step S13 and the result of the tightening failure judged in step S14, and the work information received by the receiving unit 44 as transmission information (step S15).

[0078] The control unit 45 may execute step S14 before step S13, or may execute steps S13 and S14 simultaneously.

[0079] FIG. 6 is a flowchart showing the detailed operation of step S5 shown in FIG.

[0080] The determination unit 642 determines whether or not the predetermined tightening has been accurately performed by the tool 4 based on the tightening torque setting information and torque information included in the transmission information received by the receiving unit 61 (step S21).

[0081] The determination unit 642 outputs the construction results that are a summary of the determination results of step S21, and stores them in the storage unit 62 (step S22).

[0082] FIG. 7 is a diagram showing an example of the construction result displayed on the display unit 63 in step S6 shown in FIG.

[0083] As shown in FIG. 7 , the construction results include the tools used, the calibration date of the tools used, the worker, the work time, the identification number, the set torque, the specified torque range, the tightening torque, and tightening defects (in other words, the tightening state), but may also include other information regarding the tightening of fastening parts.

[0084] In the column of tool used, the identification number of the tool 4 is displayed.

[0085] The calibration date of the tool in use field displays the date on which the tool 4 was calibrated.

[0086] The worker column displays information about the worker who performed the tightening operation, and may display, for example, the name of the worker or an identification number assigned to each worker.

[0087] The work time column displays the work time (i.e., the time when the work started) acquired by the time acquisition unit 641.

[0088] In the identification number column, identification information of the equipment 11 is displayed.

[0089] The set torque column displays the amount of torque applied to the fastening part required for the specified tightening of the equipment 11 .

[0090] The specified torque range column displays the range of torque amount used when the determining unit 642 determines whether the set torque has been reached.

[0091] The tightening torque column displays the amount of torque that the tool 4 estimates has applied to the fastened part.

[0092] The tightening failure column displays whether or not there is a tightening failure as determined by the tool 4.

[0093] For example, looking at the column for the work time of 11:00, the tightening torque is 5.0, which is within the specified torque range (4.8 to 5.2), so it can be seen that the operation of the tightening unit 46 stopped after the tightening torque reached the set torque. Also, since there is no tightening failure, it can be seen that the fastening part was tightened in the correct direction. From these, it can be seen that the fastening part was tightened accurately.

[0094] Furthermore, looking at the column for the work time of 11:05, the tightening torque is 3.5, which is outside the specified torque range (4.8 to 5.2), and so it can be seen that the operation of the tightening unit 46 stopped before the tightening torque reached the set torque. The fact that the tightening torque did not reach the set torque indicates that the operator returned the trigger switch 421 from the on position to the initial position, stopping the operation of the tightening unit 46, before the control unit 45 stopped the operation of the tightening unit 46. This shows that the fastening part in question was not tightened correctly. Furthermore, since there was no tightening failure, it can be seen that the fastening part was tightened in the correct direction.

[0095] Furthermore, looking at the column for the work time 11:13, the tightening torque was 5.0, which is within the specified torque range (4.8 to 5.2), so it can be seen that the operation of the tightening unit 46 stopped after the tightening torque reached the set torque. Also, since there was a tightening defect, it can be seen that the fastening part was tightened in the incorrect direction. From these, it can be seen that the fastening part in question was not tightened correctly.

[0096] 7 is an example, and the management device 6 may display the construction result in a predetermined format in cooperation with an existing application. Also, a column may be provided showing the overall judgment result by the management device 6 as to whether or not the fastening parts have been tightened correctly.

[0097] Furthermore, the worker or the like may customize the display so as to display only part of the data of the construction results shown in Fig. 7. For example, the management device 6 may display data excluding the tools used.

[0098] Furthermore, if there is any equipment 11 that has not been tightened, the construction result corresponding to that equipment 11 may be displayed as blank. For example, all the columns other than the identification number column shown in FIG. 7 may be displayed as blank.

[0099] As explained above, the construction management system 2 can reduce the burden on workers because construction results can be automatically compiled without the workers using the system having to transcribe the results.

[0100] In addition, the construction management system 2 can support workers, etc. by allowing them to check the construction results and confirm whether the fastening parts have been tightened correctly or whether any fastening parts have been forgotten to be tightened.

[0101] [Effects, etc.] Hereinafter, examples of inventions obtained from the disclosure of this specification will be given, and effects, etc. obtained from the inventions will be described.

[0102] Invention 1 is a construction management system 2 for a building 1 equipped with equipment 11 that requires a specified tightening by fastening parts, and includes a tool 4 that tightens the fastening parts to the equipment 11, and a transmission unit 47 that transmits torque information and work information when the tool 4 is used based on work information for the equipment 11 as transmission information to the outside, the torque information and work information including at least tightening setting torque information indicating the amount of torque required for the specified tightening to be applied to the fastening parts and identification information for the equipment 11.

[0103] Since the construction management system 2 transmits the transmission information to an external device, it is not necessary for the worker to transcribe the torque information and work information. As a result, the construction management system 2 can reduce the burden on the worker.

[0104] Invention 2 is a construction management system 2 of Invention 1, in which work information is embedded in a two-dimensional code 12, and the transmitting unit 47 transmits transmission information to the outside based on the work information embedded in the read two-dimensional code 12.

As a result, the construction management system 2 can reduce the burden on workers.

[0106] Invention 3 is the construction management system 2 of Invention 2, in which the two-dimensional code is a QR code (registered trademark).

[0107] This construction management system 2 transmits information to the outside based on the work information embedded in the read QR code (registered trademark), eliminating the need for workers to transcribe the work information.
