FIG. 1 shows an assembly procedure display system 1 according to the present embodiment. The assembly procedure display system 1 is a system that displays an assembly procedure of a construction machine. The construction machine to be displayed in the assembly procedure is composed of parts (members) assembled at a construction site, and is, for example, a Wagen. Assembly of parts may also include installation of parts at a construction site. A user who is a worker at a construction site (or a person involved in the work such as a work commander) assembles a construction machine with reference to this display. A display example in the assembly procedure display system 1 is shown in FIG. As shown in FIG. 2, the display by the assembly procedure display system 1 is a three-dimensional display in which the parts to be assembled are displayed three-dimensionally.

As shown in FIG. 1, the assembly procedure display system 1 includes a terminal 10 and a reader 20. The terminal 10 is a device that displays an assembly procedure, and is used by a user who is a worker at a construction site. The terminal 10 is a computer including hardware such as a CPU (Central Processing Unit), a memory, and a communication module. Specifically, the terminal 10 is a PC (personal computer), a tablet terminal, or the like. The terminal 10 has a function normally possessed by a PC, a tablet terminal, or the like. In the present embodiment, the terminal 10 includes a display device that displays a display or the like.

Each function of the terminal 10 according to the present embodiment, which will be described later, is realized by operating the above-mentioned components by a program or the like. For example, each function according to the present embodiment is realized by reading and executing data in which the functions related to the present embodiment (including information used by the functions) are stored by an application that can use the data. NS. The above data can be, for example, an assembly work procedure manual, and a conventional PDF (Portable Document Format) (3D-PDF) file can be used. For added security, the above data may be password protected. The above application can use a conventional PDF viewer.

The reader 20 is a detection means provided at the construction site, which is the assembly site, detects the carry-in of the parts of the construction machine to the construction site, and outputs the carry-in parts information indicating the parts brought into the construction site to the terminal 10. It is a device. Specifically, the reader 20 is a reader that reads information from an RF tag of RFID (Radio Frequency IDentification). As the reader 20, a conventional RFID reader can be used. The reader 20 is installed, for example, at a construction site at a gate through which a vehicle such as a truck or trailer for carrying parts passes. An RF tag that stores information that identifies the component is attached to each component. When the vehicle passes through the place where the reader 20 is installed, the reader 20 reads the information from the RFID tag attached to the parts loaded on the vehicle to bring the parts of the construction machine to the construction site. Detect. The reader 20 has a communication function so that information can be transmitted to the terminal 10. When the reader 20 reads the information from the RFID tag, the reader 20 transmits the read information to the terminal 10 via a communication network such as a LAN (local area network). The information read by the reader 20 may be once transferred to the server and transmitted from the server to the terminal 10.

Subsequently, the function of the terminal 10 according to the present embodiment will be described. As shown in FIG. 1, the terminal 10 includes a storage unit 11, a carry-in component information input unit 12, and a display unit 13.

The storage unit 11 is a storage means for storing three-dimensional information for three-dimensionally displaying each part of a construction machine. The three-dimensional information includes information that enables the user to visually grasp the assembly procedure, for example, the three-dimensional shape of the part, the relative position of the part when assembling the construction machine, and the order when the part is assembled. Is done. That is, the three-dimensional information includes information indicating where and how each component is attached. The storage unit 11 stores the three-dimensional information of each component in association with the information for identifying the component. As a result, the three-dimensional information of each component can be identified on the terminal 10 as to which component information.

Further, the storage unit 11 stores the three-dimensional information of each component in association with the assembly step. One step (process) of assembly corresponds to the assembly of a series of parts group units divided so that they can be rationally assembled. In the case of wagen assembly, rail assembly, mainframe assembly, and the like correspond to one step.

The three-dimensional information is generated in advance by the assembly procedure display system 1, input to the terminal 10, and stored in the storage unit 11. The three-dimensional information is generated in advance by the administrator of the assembly procedure display system 1 by using the three-dimensional information of the parts generated by the conventional CAD software used in CIM (Construction Information Modeling / Management).

Further, the storage unit 11 stores information (attribute information) related to parts other than the three-dimensional information for three-dimensional display. The information is, for example, information indicating a part name, material, dimension, quantity, weight, etc., and is stored in the table shown in FIG. This information is also associated with the information for identifying the member, and the information of which part can be identified by the terminal 10.

Further, the storage unit 11 further stores incidental information associated with the assembly other than the three-dimensional information for each assembly step. For example, the storage unit 11 stores safety equipment information, personnel allocation information, trouble case information, and the like as incidental information. The safety equipment information is information indicating equipment necessary for assembly and safety equipment (for example, curing of openings, handrails, etc.). The personnel allocation information is information indicating the movement (posture) of a person at the time of assembly and the arrangement position of the personnel. The trouble case information is information indicating a trouble case. The accompanying information may be text information or information displayed together with the three-dimensional information of the parts (for example, information visually indicating the staffing position).

The carry-in part information input unit 12 is a carry-in part information input means for inputting carry-in part information indicating the parts brought into the construction site. The carry-in part information input unit 12 receives and inputs the information for identifying the part transmitted from the reader 20 as the carry-in part information. After inputting the information, the carry-in part information input unit 12 outputs the information to the display unit 13.

The display unit 13 is a display means that uses the three-dimensional information stored by the storage unit 11 to perform a three-dimensional display indicating a parts assembly procedure for each step of assembling a construction machine. The display unit 13 displays a three-dimensional moving image as the three-dimensional display. Further, the display unit 13 displays according to the carry-in part information input by the carry-in part information input unit 12. In addition, the display unit 13 displays the incidental information stored by the storage unit 11 together with the three-dimensional display. Specifically, the display unit 13 displays as follows.

The display unit 13 inputs a display trigger after the assembly step is specified. The display trigger is, for example, an operation on the terminal 10 of the user. The operation is for designating the assembly step and displaying the display. The display unit 13 reads out the three-dimensional information of the parts related to the specified assembly step from the storage unit 11 and puts it in a preset area (for example, the area 100 shown in FIG. 2) in the display area displayed by the display device. Performs a three-dimensional display. The three-dimensional display is an image of observing the place where the parts are assembled from the set viewpoint position and the direction of the line of sight. The three-dimensional display shows the assembly procedure of the parts in sequence. For example, the three-dimensional display is a display of a three-dimensional moving image that shows the movement of assembling parts. The three-dimensional display does not necessarily have to be a moving image. For example, the display may be such that the assembly procedure can be grasped by switching the three-dimensional display according to the operation of the user on the terminal 10.

In addition, the display unit 13 can change the position of the viewpoint and the direction of the line of sight according to the user's operation on the terminal 10. Further, the display unit 13 may be able to enlarge or reduce the image, rewind the moving image, or the like according to the operation or the like of the user on the terminal 10. Further, the cross section of a portion having a complicated structure and difficult to understand may be freely cut or enlarged to be shown.

The display unit 13 inputs information for specifying a component as the import component information from the import component information input unit 12. When the information is input, the display unit 13 displays the part indicated by the information in the above three-dimensional display so that the other parts can be distinguished from each other. For example, as shown in FIG. 2, the color of the component (hexagon bolt in the example of FIG. 2) 101 indicated by the information is displayed by changing the color of the other component. Specifically, if the display color of a normal part is gray, the display is changed to red. The display unit 13 may perform a three-dimensional display of the part about the step in which the part is used for assembly, using the input of the information for identifying the part from the carry-in part information input unit 12 as a trigger. That is, the display trigger may be used as an input of information for identifying a component.

The display unit 13 reads information other than the three-dimensional information such as the name, material, and dimensions of the parts displayed in three dimensions from the storage unit 11, and together with the three-dimensional display, is an area where the three-dimensional display is performed. It is displayed in another preset area (for example, the area 110 shown in FIG. 2). Alternatively, the display unit 13 may superimpose and display the information on the area where the three-dimensional display is performed. The display may be performed on, for example, a part specified by the information input from the carry-in part information input unit 12, or a part designated by a user's operation on the three-dimensional display.

Further, the display unit 13 reads out the accompanying information related to the displayed assembly step from the storage unit 11 and displays it together with the three-dimensional display. For example, if the accompanying information is text information, the display is displayed in a preset area different from the area where the three-dimensional display is performed. Further, if the accompanying information is information to be displayed together with the three-dimensional information of the part (for example, information visually indicating the arrangement position of personnel), it is displayed in the area where the three-dimensional display of the part is performed. The above is the function of the terminal 10 according to the present embodiment.

Subsequently, the process executed by the assembly procedure display system 1 according to the present embodiment will be described with reference to the flowchart of FIG. In this process, first, in the terminal 10, the display unit 13 inputs a trigger for displaying the user's operation on the terminal 10 (S01). Subsequently, the display unit 13 reads out the three-dimensional information stored by the storage unit 11, and performs a three-dimensional display indicating the assembly procedure of the parts (S02). At this time, information other than the three-dimensional information such as the name, material, and dimensions of the parts, and incidental information related to the displayed assembly step are also displayed.

Here, when the parts are brought into the construction site by a truck, a trailer, or the like, the reader 20 reads the information from the RFID tags of the parts and transmits the information to the terminal 10. At the terminal 10, information for identifying the imported parts is received and input by the imported parts information input unit 12 (S03). Subsequently, the display unit 13 changes the color of the carried-in part specified by the information and displays it (S04). For example, the part is displayed in red instead of the usual gray display as described above.

A worker who performs assembly work at a construction site performs assembly work with reference to the above display on the terminal 10. When the assembly is completed for each step, it is confirmed whether each assembly is performed reliably by checking the assembly accuracy by image measurement, laser survey, etc., and checking the tension of the tightening bolt, and when the step is completed, the next step is started. Will be done. The above is the process executed by the assembly procedure display system 1 according to the present embodiment.

As described above, according to the present embodiment, at a construction site or the like, a worker can refer to a three-dimensional display showing an assembly procedure of a construction machine and grasp how to assemble the parts. Since the display according to the present embodiment is a three-dimensional display, the worker can immediately collate with the actual product and can intuitively grasp the assembly procedure of the parts. That is, the present embodiment "visualizes" the assembly. Therefore, according to the present embodiment, the worker can easily and surely assemble the construction machine at the construction site. This improves the safety and productivity of the actual assembly work.

Further, the member brought into the construction site as in the present embodiment may be displayed separately from other members. By performing such a display, the worker can easily grasp which part should be brought into the construction site and assembled. According to this configuration, it is possible to easily grasp which parts have been brought into the construction site and how to assemble each of the brought-in parts. In the present embodiment, the color of the parts is changed, but if the other parts can be distinguished, they may be displayed by another method.

Further, like the reader 20 of the present embodiment, the assembly procedure display system 1 may be provided with a detection means for detecting the delivery of parts. According to this configuration, it is possible to easily and surely detect the delivery of parts to the construction site. As a result, it is possible to easily and surely display the carried-in member. However, in the assembly procedure display system 1, even if the assembly procedure display system 1 does not have a configuration related to display of the carried-in member (that is, a configuration related to the carry-in part information input unit 12 of the reader 20 and the terminal 10). good.

Further, it may be displayed as a moving image as in the present embodiment. According to this configuration, the worker can grasp the assembly procedure of the parts more intuitively, and can grasp the assembly procedure more easily and appropriately.

Further, as in the present embodiment, the accompanying information may also be displayed. According to this configuration, at each assembly step, the worker can grasp various information associated with the assembly, such as information on safety and information on personnel required for the assembly. As a result, the staffing at the time of assembly and points to be noted regarding dangerous work are clarified for each assembly step, and the safety and productivity of the actual assembly work are further improved.
