[Technical field]

[0001] The present invention relates to a construction management system, a construction management method, and a construction management program for managing construction work using lifting equipment such as a crane. [Background technology]

[0002] An information management system for managing the progress of construction work is under consideration (see, for example, Patent Document 1). The control unit of the management server described in this document records the acquired identification information and performance status of parts in a part information storage unit. Then, when search conditions related to the period, performance status, and part of the structure to be searched are acquired from a user terminal, identification information of parts that correspond to the search conditions in the BIM information storage unit and have performance statuses that correspond to the search conditions in the part information storage unit is identified. The progress of the construction work is then calculated using quantities related to the structure's configuration contained in the BIM information of the parts.

[0003] A construction management system for supporting lifting work is also under consideration (see, for example, Patent Document 2). The control unit of the lifting support system described in this document acquires information on the hanging position of the load from the drive control unit, and acquires three-dimensional measurement information including the shape of the load from the position measurement device. Then, the size of the load at the position corresponding to the hanging position information is identified in the three-dimensional measurement information. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2022-189152 A [Patent Document 2] JP 2022-110436 A Summary of the Invention [Problem to be solved by the invention]

[0005] As described in Patent Document 1, progress management of construction work can be performed according to the usage record of parts. However, if it takes time to identify parts at the construction site, efficient progress management cannot be realized. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of a construction management system, a construction management method, and a construction management program will be described with reference to Figures 1 to 11. In this embodiment, the construction management system will be described as being used when a lifting device (tower crane) is used at a construction site of a building B1.

[0010] 1, this embodiment uses a control unit 10, a support server 20, and a management terminal 30, which are interconnected via a network. The control unit 10 is provided on a crane C1 serving as a first lifting device. As shown in Fig. 2, a rotating frame C11 is placed on a mast C10 of the crane C1, and a driver's seat C12 is provided on the rotating frame C11. When lifting work is performed by an operator, the operator uses the driver's seat C12 of the crane C1 to perform the rotation of the rotating frame C11, the raising and lowering (tilt angle) of the jib C13 (boom), and the raising and lowering of the hook C15 by reeling out the wire C14. Then, a load C16 suspended from the hook C15 is transported. Note that the operator can also perform the operation by remote control or automatic driving.

[0011] (Hardware configuration description) 3, the hardware configuration of the information processing device H10 constituting the control unit 10, the support server 20, and the management terminal 30 will be described. The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is an example, and it is also possible to realize it using other hardware.

[0012] The communication device H11 is an interface that establishes a communication route with other devices and transmits and receives data, and is, for example, a network interface or a wireless interface.

[0013] The input device H12 is a device that accepts input of various information, such as a mouse, a keyboard, etc. The display device H13 is a display or the like that displays various information. The storage device H14 is a storage device that stores data and various programs for executing various functions of the control unit 10, the support server 20, and the management terminal 30. Examples of the storage device H14 include a ROM, a RAM, and a hard disk.

[0014] The processor H15 uses programs and data stored in the storage device H14 to control each process in the control unit 10, the support server 20, and the management terminal 30. Examples of the processor H15 include a CPU and an MPU. The processor H15 expands programs stored in a ROM or the like into a RAM and executes various processes for each process.

[0015] The processor H15 is not limited to a processor that performs software processing for all the processes it executes. For example, the processor H15 may include a dedicated hardware circuit (e.g., an application specific integrated circuit (ASIC)) that performs hardware processing for at least a part of the processes it executes. That is, the processor H15 may be configured as follows:

[0016] [1] One or more processors that operate according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes; or [3] Circuits that include combinations of these The processor includes a CPU and memory, such as RAM and ROM, that stores program codes or instructions configured to cause the CPU to execute processes. Memory, i.e., computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0017] (System Configuration) Next, using Figure 1, we will explain each function of the construction management system. The control unit 10 provided on the crane C1 includes a position measuring device 12, an imaging device 13, and a drive control unit .

[0018] The position measuring device 12 is installed near the hook C15. This position measuring device 12 can obtain information regarding latitude, longitude, and altitude by using a Global Navigation Satellite System (GNSS). This makes it possible to identify the position of the hook C15 and the position of the suspended load C16.

[0019] The imaging device 13 is provided at the tip of the jib C13 of the crane C1 and takes video of the lower hook C15 and the suspended load C16. The imaging device may also be disposed at a position where it can overlook the entire site or the entire crane C1.

[0020] The drive control unit 14 performs drive control in response to the operator's instructions for the rotation operation of the rotating frame C11, the raising and lowering operation of the jib C13, and the up and down operation of the hook C15. Then, the control unit 10 transmits the position information from the position measurement device 12 , the video from the imaging device 13 , and the drive information from the drive control unit 14 to the support server 20 .

[0021] The support server 20 is a computer system that supports construction progress management by using information acquired from the control unit 10. The support server 20 includes a control unit 21, a BIM information storage unit 22, and a lifting information storage unit 24.

[0022] The control unit 21 performs processes (including an information acquisition stage, a judgment stage, a management stage, etc.) described below. The control unit 21 functions as an information acquisition unit 211, a judgment unit 212, a management unit 213, etc., by executing a program for each process.

[0023] The information acquisition unit 211 acquires various pieces of information from the control unit 10. In this embodiment, position information and a video of the area below the tip of the jib C13 are acquired from the control unit 10. The position information makes it possible to identify the position of the load C16. In addition, the video makes it possible to confirm the load C16. The information acquisition unit 211 acquires from the control unit 10 operation information such as hoisting operation information of the jib C13, rotation operation information of the rotating frame C11, and the load of the wire C14 due to the suspended load C16.

[0024] The determination unit 212 determines whether the load C16 is lifted or placed. The management unit 213 executes a process for managing the progress of construction work.

[0025] 4, BIM data 220 created in BIM (Building Information Modeling) is recorded in the BIM information storage unit 22 as a design information storage unit. This BIM data 220 is recorded when a structure to be constructed at a construction site is designed using a three-dimensional CAD. The BIM data 220 as three-dimensional model information includes project information, element models, attribute information, arrangement information, and progress information.

[0026] The project information includes information on the construction site ID of building B1, the name of the project, the longitude and latitude, the direction of the construction site, etc. The element model is information regarding a three-dimensional model (BIM object) of each architectural element (component) used in the construction of building B1.

[0027] The attribute information is the attribute information of this element model. This attribute information includes information related to specifications (element ID, element type, standard, dimensions, area, volume, weight, material, etc.). The placement information includes information about the coordinates at which each element model is placed. The latitude and longitude can be specified by these coordinates.

[0028] Furthermore, in the placement information, the coordinates are associated with the planned date on which each element model is to be installed. The progress information is recorded as the actual date when the components of this element model were installed.

[0029] 5, lifting management data 240 relating to the lifting work using the crane C1 is recorded in the lifting information storage unit 24. This lifting management data 240 is recorded when various information is acquired from the management terminal 30. The lifting management data 240 includes information relating to the site ID, crane ID, work ID, lifting member identifier, movement trajectory, and video.

[0030] The site ID is information regarding an identifier for identifying the site where lifting work is performed by the crane C1. The crane ID is information regarding an identifier for identifying the crane C1 used in each lifting operation.

[0031] The job ID is an identifier for identifying the lifting job performed using this crane C1. The lifted member identifier is an identifier for identifying the member transported by this lifting work. In this embodiment, the element ID recorded in the BIM information storage unit 22 is used.

[0032] The movement trajectory is information about the trajectory of the position of the hook C15 from the start of lifting to the end of lifting. This trajectory is composed of date, time, and coordinates. The video is a video captured using the imaging device 13.

[0033] The management terminal 30 is a computer terminal used by a manager of the construction site. The manager uses the management terminal 30 to manage the progress of the construction work.

[0034] (Construction management processing) Next, the procedure of the construction management method using lifting work will be described with reference to Figs. First, as shown in Fig. 6, the control unit 21 of the support server 20 executes a process of acquiring transport information (step S101). Specifically, the information acquisition unit 211 of the control unit 21 acquires operation information of the crane C1. Then, the determination unit 212 determines that transport has started when it detects that the load C16 has been suspended from the crane C1. This suspension of the load C16 is detected by an increase in the load on the wire C14, etc. In this case, the determination unit 212 assigns a task ID to the lifting task.

[0035] Next, the control unit 21 of the support server 20 executes a hook position identification process (step S102). Specifically, the information acquisition unit 211 of the control unit 21 sequentially acquires position information of the hook C15 from the position measurement device 12. Furthermore, the information acquisition unit 211 acquires a video of the suspended load from the imaging device 13. In this case, the information acquisition unit 211 records the position (movement trajectory) of the hook C15 and the video in the lifting information storage unit 24 in the lifting management data 240 in which the work ID is recorded.

[0036] Next, the control unit 21 of the support server 20 executes an installation determination process (step S103). Specifically, the determination unit 212 of the control unit 21 determines whether the load C16 has landed (installed) at a predetermined position. In this case, the determination unit 212 detects whether the load C16 has been installed based on a reduction in the load applied to the wire C14. If the load C16 has not been installed, the hook position identification process (step S102) continues.

[0037] On the other hand, if it is determined that the load C16 has been installed, the control unit 21 of the support server 20 executes a process for identifying a lifting member (step S104). Specifically, the determination unit 212 of the control unit 21 identifies the installation position (latitude, longitude, altitude) of the load C16 based on the position information acquired from the position measurement device 12. Next, the determination unit 212 extracts BIM data 220 corresponding to the installation position from the BIM information storage unit 22. Then, the determination unit 212 identifies the member of the extracted BIM data 220 as the lifting member.

[0038] Next, the control unit 21 of the support server 20 executes a process of reflecting the progress information (step S105). Specifically, the management unit 213 of the control unit 21 updates the progress information (installed) of the BIM data 220. Furthermore, the management unit 213 records the element ID of the identified member in the lifting management data 240 of the lifting information storage unit 24.

[0039] When the manager wants to check the progress of the construction work, he uses the management terminal 30. A management screen is output to the display device H13 of this management terminal 30. Then, the manager selects the desired information on the management screen. In this embodiment, the manager can select "Check the trajectory," "Construction plan," "Construction progress," etc.

[0040] Next, the control unit 21 of the support server 20 executes an output request acquisition process (step S106). Specifically, the management unit 213 of the control unit 21 acquires the output request from the management terminal 30. In "trajectory confirmation", the desired work ID and work time range are specified. In "construction plan" and "construction progress status", the desired request date is specified.

[0041] Next, the control unit 21 of the support server 20 executes an output process of the requested information (step S107). Specifically, the management unit 213 of the control unit 21 outputs a display screen corresponding to the output request to the display device H13 of the management terminal 30 using the three-dimensional model recorded in the BIM information storage unit 22.

[0042] When an output request for "Confirm trajectory" is acquired, the management unit 213 acquires the lifting management data 240 for the work ID and work time range of the output request from the lifting information storage unit 24. Then, the management unit 213 generates and outputs a display screen showing the movement trajectory recorded in the lifting management data 240. Furthermore, the management unit 213 identifies from the BIM information storage unit 22 whether or not the actual date is recorded in the element model used for building B1.

[0043] 7, the management unit 213 outputs a display screen 400 showing a trajectory 410 for a predetermined period of time. On this display screen 400, a constructed model 411 and an unconstructed model 412 are displayed depending on whether or not the actual date is recorded.

[0044] When an output request for the "construction plan" is acquired, the management unit 213 acquires element models used for the building B1 from the BIM information storage unit 22. A display screen that can identify element models for which a scheduled date is set before the requested date is generated and output.

[0045] As shown in FIG. 8, for example, when a requested date (nth day) is acquired, the management unit 213 outputs a display screen 500. On the display screen 500, a surface model 50a indicates components that have been constructed, and a frame model 50b indicates components that are scheduled to not be constructed on the requested date (nth day). Here, the surface model means a model in which the surface of a component is filled with a specified color. Also, the frame model means a model in which the surface of a component is colorless. Note that the present invention is not limited to a surface model and a frame model, and it is sufficient if it is possible to distinguish between constructed and unconstructed.

[0046] 9, when the requested date (n+i day) is acquired, the management unit 213 outputs a display screen 510. On the display screen 510, the surface model 50a shows the constructed members, and the frame model 50b shows the members that are scheduled to be constructed on the requested date (n+i day).

[0047] In addition, when a "construction progress request" is acquired, the element models for the planned dates and actual dates before the requested date are identified in the BIM information storage unit 22. When an output request for "construction progress status" is acquired, the management unit 213 identifies element models in which actual dates are recorded in the BIM data 220 recorded in the BIM information storage unit 22. Furthermore, the management unit 213 identifies element models whose planned dates are earlier than the requested date. Then, the management unit 213 calculates the difference between the actual dates and the planned dates for each element model. In this case, the management unit 213 changes the color scheme of the surface model depending on the difference.

[0048] In this case, as shown in Fig. 10, when the required date (n days) is acquired, the management unit 213 outputs a display screen 520. For the required date (n days), the surface model 52a indicates "more than 5 days ahead of schedule", and the surface model 52b indicates "less than 5 days ahead of schedule". Furthermore, the surface model 52c indicates "as planned", the surface model 52d indicates "less than 5 days late", and the surface model 52e indicates "more than 5 days late". Furthermore, the frame model 52f indicates components that have not yet been constructed. 11, when the requested date (n+i day) is acquired, a display screen 530 is output. In the display screen 530, the unconstructed members have disappeared.

[0049] (Operation of the embodiment) Since the installation positions of components are registered in the BIM information storage unit 22, if the installation positions can be identified by lifting work, the components can be identified.

[0050] (Effects of the embodiment) According to this embodiment, the following effects can be obtained. (1) In this embodiment, the control unit 21 of the support server 20 executes a process of acquiring transport information (step S101). This makes it possible to identify the start of a lifting operation. (2) In this embodiment, the control unit 21 of the support server 20 executes a hook position identification process (step S102), thereby making it possible to identify the position of the load C16.

[0051] (3) In this embodiment, the control unit 21 of the support server 20 executes an installation determination process (step S103), which makes it possible to identify the installation position of the load C16. (4) In this embodiment, the control unit 21 of the support server 20 executes a process for identifying a lifting member (step S104). This makes it possible to identify the lifting member according to the installation position of the suspended load C16.

[0052] (5) In this embodiment, the control unit 21 of the supporting server 20 executes a process of reflecting the progress information (step S105). This allows the progress status to be promptly registered according to the lifting work situation.

[0053] (6) In this embodiment, the control unit 21 of the support server 20 executes an output request acquisition process (step S106) and a request information output process (step S107), thereby making it possible to grasp the progress of the construction work.

[0054] (7) In this embodiment, the control unit 21 of the support server 20 outputs information regarding "trajectory confirmation," "construction plan," and "construction progress." "Trajectory confirmation" allows visual confirmation of the movement of the hook C15 during transportation. "Construction plan" allows visual confirmation of the construction method of the building B1. "Construction progress" allows visual confirmation of any discrepancies between the construction plan and the actual results.

[0055] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. In the above embodiment, a tower crane is assumed as the lifting device, but the lifting device is not limited to a tower crane. Also, in the above embodiment, one crane is assumed, but the present invention may be applied to multiple or more cranes.

[0056] In the above embodiment, the position measuring device 12 and the imaging device 13 are used, but as long as the state of the suspended load C16 can be observed, the present invention is not limited to these. For example, a three-dimensional measuring device may be used. This three-dimensional measuring device is provided at the tip of the jib C13 of the crane C1 to acquire a three-dimensional image of the surrounding area below. The three-dimensional measuring device may also be provided near the driver's seat C12 of the rotating frame C11 to acquire a three-dimensional image of the surrounding area below the jib C13. The three-dimensional measuring device detects the positional relationship between the suspended load C16 and the surrounding area using, for example, laser light. For this three-dimensional measuring device, for example, LiDAR (Light Detection and Ranging) technology that acquires three-dimensional point cloud information as three-dimensional detection information can be used. Here, for example, laser light installed at two different positions is used as the LiDAR. Then, the scan plane formed by scanning each laser light one-dimensionally is rotated 360 degrees in the normal direction.

[0057] In the above embodiment, the control unit 21 of the support server 20 outputs information related to "trajectory confirmation," "construction plan," and "construction progress status." The information to be output is not limited to these. For example, the operating rate of the crane C1 may be calculated. In this case, the elapsed time from the start to the end of the lifting work is used.

[0058] In the above embodiment, the control unit 21 of the support server 20 executes a process for acquiring transport information (step S101). The hanging of the load C16 is detected by an increase in the load of the load C16, etc. The detection of the hanging is not limited to this. For example, the presence of the load C16 and the slinging work (attachment) may be detected by image recognition using a video.

[0059] In the above embodiment, the control unit 21 of the support server 20 executes a hook position identification process (step S102). Specifically, the information acquisition unit 211 of the control unit 21 acquires position information of the hook C15 from the position measurement device 12. The identification method is not limited to this. For example, the position of the hook C15 and the position of the suspended load C16 may be identified according to the rotation operation of the rotating frame C11 and the raising and lowering (tilt angle) operation information of the jib C13 (boom) acquired from the drive control unit 14, and the payout amount of the wire C14.

[0060] The control unit 21 of the support server 20 also executes an installation determination process (step S103). In this case, the determination unit 212 detects whether the load C16 has been installed based on a reduction in the load applied to the wire C14. In this case, the suspension of the load C16 based on a video, the slinging work (removal), and the like may also be detected by image recognition. Furthermore, the weight may be obtained from the attribute information of the element model recorded in the BIM information storage unit 22, and the load and weight at the time of lifting may be compared to confirm the components identified at the installation position. In addition, the photographed image may be used to identify the installation orientation of the object to be lifted, and the identified member may be confirmed at the installation position.

[0061] In the above embodiment, the control unit 21 of the support server 20 executes a process for identifying the lifting member (step S104). Here, the installation position (latitude, longitude, altitude) of the suspended load C16 is used. The method for identifying the lifting member is not limited to this. For example, the lifting member may be identified using the payout amount of the wire C14, the longitude, and the latitude. Also, at the time of installation, the BIM information storage unit 22 may be used to identify the constructed member by longitude and latitude, and the member directly above this constructed member may be identified as the lifting member.

[0062] Next, the technical ideas that can be understood from the above-described embodiment and other examples will be described below. (a) The construction management system according to claim 1, characterized in that the control unit acquires latitude and longitude information of the suspended load from the lifting device and identifies the position of the object to be lifted using the latitude and longitude information.
