Therefore, the user can determine whether the use plan of the crane is appropriate by using the calculation result, and can efficiently create the construction plan.

  A first embodiment will be described with reference to FIGS. FIG. 1 shows the overall configuration of the construction plan support apparatus 1. The construction plan support apparatus 1 can be composed of, for example, one or a plurality of computers. Here, the case where it comprises from one computer is demonstrated.

  [System configuration]

  The construction plan support device 1 is a device for supporting the planning of a crane arrangement plan, and is configured using a computer such as a personal computer, for example. The construction plan support device 1 includes, for example, a microprocessor (CPU: Central Processing Unit) 10, a storage device 11, a memory 12, an input device 13, an output device 14, and a communication device 15. ˜15 are connected by a bus 16. The construction plan support apparatus 1 is communicably connected to the plant 3D model database 2, the building process database 3, and the crane specification database 4 via the communication device 15 and the communication network 15.

  The storage device 11 is configured as a nonvolatile storage device having a relatively large storage capacity such as a hard disk drive or a flash memory device, for example, and an information management unit 110 and a crane work area model generation unit 111 as described later. The computer program for realizing the crane load mapping unit 112, the carry-in period calculation unit 113, the crane usage time calculation unit 114, the calculation result storage unit 115, and the information presentation screen generation unit 116 is stored. In FIG. 1, the operating system and device drivers are not shown.

  The memory 12 is, for example, a RAM (Random Access Memory) or a ROM (Read Only Memory). The memory 12 is used for the microprocessor 10 and provides a work area for the microprocessor 10.

  The input device 13 is a device for a user to input information to the construction plan support device 1, and includes, for example, a pointing device such as a keyboard, a touch panel, and a mouse, a line-of-sight detection device, a voice instruction device, and a motion detection device. Can be configured. The output device 14 is a device for outputting information from the construction plan support device 1, and can be configured to include, for example, a display, a printer, a voice synthesizer, and the like. For example, an external device such as a mobile phone or a personal digital assistant may be connected to the construction plan support device 1 so that information can be input and output.

  The communication device 15 is connected to the databases 2 to 4 through the communication network CN, and is a device for communicating with these databases 2 to 4. Each database 2-4 may be provided in the construction plan support apparatus 1, or only necessary data among the data of each database 2-4 may be copied into the construction plan support apparatus 1 and used. . Alternatively, data required by the construction plan support apparatus 1 may be manually input to the construction plan support apparatus 1 by the user via the input device 13. Alternatively, the data required by the construction plan support apparatus 1 may be stored in a storage medium, and the storage medium may be connected to the construction plan support apparatus 1 to read the data.

  The information management unit 110 has a function of reading data from each database 2 to 4 and writing data to each database 2 to 4. The information management unit 110 realizes a “three-dimensional model data management unit” by connecting to the plant 3D model database 2. The information management unit 110 realizes a “building process data management unit” by connecting to the building process database 3. The information management unit 110 constitutes a “crane specification data management unit” by connecting to the crane specification database 4.

  The crane work area model generation unit 111 has a function of generating a 3D model of the work area for each crane 5 (see FIG. 6) arranged at the construction site. The processing of the crane work area model generation unit 111 will be described later with reference to FIG.

  The crane load mapping unit 112 has a function of determining and associating a load target (building structure, equipment) to be loaded by each crane. The crane carry-in mapping unit 112 corresponds to a “crane carry-in handling unit”.

  The carry-in period calculation unit 113 is a function for calculating a period during which a carry-in object associated with each crane is to be carried. For example, large equipment and piping spools need to be carried in before assembling the ceiling of the place where the installation is planned, and therefore the carry-in time is calculated.

  The crane usage time calculation unit 114 is a function that calculates the amount of crane usage (crane usage) used to carry in the object to be carried in as the crane usage time. The crane usage time calculation unit 114 corresponds to a “crane usage amount calculation unit”.

  The calculation result storage unit 115 stores the results calculated by the functions 111 to 114. The information presentation screen generation unit 116 corresponds to an “information providing unit” and has a function of generating a screen to be provided to the user via the output device 14.

  [data structure]

  A configuration example of the databases 2 to 4 will be described with reference to FIGS. First, the configuration of the plant 3D model database 2 will be described with reference to FIG. 2, followed by the configuration of the building process database 3 with reference to FIG. 3, and finally the configuration of the crane specification database 4 with reference to FIG. explain. Each of the databases 2 to 4 may include items other than the illustrated items. Moreover, you may comprise each database 2-4 by making a some database cooperate.

  [Plant 3D model database]

  As shown in FIG. 2, a record is registered in the plant 3D model database 2 for each individual part constituting the plant as “building”. Of the parts that make up the plant, those that are carried in using a crane correspond to “objects to be carried in”. Each record stores, for example, project ID 20, part ID 21, shape information 22, coordinate information 23, structure type 24, attribute 25, and the like. The record may include information other than these. ID is an abbreviation for IDentification.

  The project ID 20 is information for identifying a project for constructing a plant, and is, for example, a character string representing a plant name. The component ID 21 is information for uniquely identifying each component, and is composed of, for example, a character string. The shape information 22 is information indicating the shape of the part, and examples of the shape include a straight pipe, an elbow, and a rectangular parallelepiped.

  The coordinate information 23 is information indicating the spatial position of the part in the plant construction work area. For example, if the shape is a straight pipe or an elbow, the shape can be defined by the center coordinates of the circle forming the two end faces (for example, the top face and the bottom face) and the radius thereof. If the shape is a rectangular parallelepiped, it can be defined by the information of the 12 line segments. Information of each line segment can be defined by the coordinates of two points at both ends thereof.

  The structure type 24 is information indicating the type of structure represented by the 3D CAD component. The parts as the objects to be carried in include “building structure” and “equipment”. Here, the “equipment” may be described including piping. “Building structures” include, for example, housings such as foundations, floors, ceilings, and walls. “Equipment” includes, for example, a control panel, an air conditioner, an air conditioning duct, a large display device, an electric cable tray, and piping.

  The attribute 25 is product information given to each object in 3DCAD. For example, in the case of equipment or piping, the system name and construction drawing number are set as attribute values. The system name is a unit grouped by function during plant operation. For example, in the case of a frame, “floor”, “wall”, “floor” and the like are set as attribute values.

  [Building process database]

  As shown in FIG. 3, a plurality of records are registered in the building process database 3 in units of individual schematic processes included in the schematic construction process plan. In each record, for example, project ID 30, work process ID 31, structure type 32, work name 33, work start date 34, work completion date 35, attribute 1_36, and attribute 2_37 are stored.

  The project ID 30 is information for identifying a plant construction project to which the building process belongs. For example, information (name or the like) for identifying a plant is set. This makes it possible to distinguish between past construction projects and current construction projects.

  The work process ID 31 is an identifier that is assigned to uniquely identify each work process constituting the process table. The structure type 32 is information indicating the type of structure handled in the work process specified by the work process ID. The work name 32 is information for identifying a work described in a process chart or the like. For example, a character string such as “1F-wall construction” or “1F-ceiling construction” is set.

  The work start date 34 is a date when the work of the work process starts. The work completion date 35 is a date for completing the work of the work process. The date is set as “2013/02/01” (year / month / day), for example. The attribute 1_36 and the attribute 2_37 are information for associating each work process with the work target part. For example, the name of the work floor of each work and whether the work target frame is a floor or a wall. A character string to be distinguished is set.

  [Crane specification database]

  As shown in FIG. 4, records for each crane are registered in the crane specification database 4. Each record stores, for example, a project ID 40, a crane name 41, coordinates 42, a boom length 43, a lifting load 44, a work radius 45, and an operator skill level 46.

  The project ID 40 is information for identifying a plant construction project. The crane name 41 is information for identifying a crane used in the project. The coordinates 42 are information for specifying the installation location of the crane at the work site. The boom length 43 indicates the length of the boom 54 (see FIG. 6) of the crane. The working radius 45 is a radius when the workable area of the crane is defined as a circle.

  The operator skill level 46 is information indicating the skill level of the operator who operates the crane. When a plurality of operators operate the same crane by turns, the skill level of each operator is set. Hereinafter, details of processing contents of the functions 111 to 114 illustrated in FIG. 1 will be described.

  [Crane work area model generation unit 111]

  FIG. 5 is a flowchart showing processing executed by the crane work area model generation unit 111. The crane work area model generation unit 111 acquires the name, work radius, and coordinates of the crane to be processed from the crane specification database 4 (S10). Instead of reading the crane name or the like from the database 4, the user may input it manually.

  The crane work area model generation unit 111 generates a cylindrical work area model having a work radius as the center with the crane coordinates as the center, and stores the crane work area model (S11). A specific value may be set in advance for the height of the cylindrical shape, or a value designated by the user with the input device 2 may be read.

  The crane work area model generation unit 111 determines whether work area models have been generated for all cranes to be processed (S12). If there is an unprocessed crane (S12: NO), that is, if there is a crane that has not created a crane work area model, the process returns to step S11.

  FIG. 6 is an explanatory diagram showing the result of executing the above-described crane work area model generation process as a top view. In the example of FIG. 6, a plurality of cranes 5 are arranged in the construction area 60 of the building 6 (see FIG. 9) and its periphery. A turning center 50 of the crane 5 is shown as an installation position of the crane. If the sign of each crane is expressed as 5 (1) -5 (6), the sign of the installation position (turning center) of each crane 5 (1) -5 (6) is 50 (1) -50 (6). Become.

  The crane work area WZ of each crane 5 is defined as a columnar object having a center at the crane installation position 50 and a work radius WD. The height of the cylinder can be determined as appropriate. For example, the height of the cylinder can be determined based on the boom length included in the specification information 4 of the crane 5 and the boom angle at the time of work. In FIG. 6, almost all of the construction area 60 is covered with at least one of the work areas WZ <b> 1 to WZ <b> 6 of each crane 5. In addition, the crane arrangement | positioning shown in FIG. 6 is an example, and 2 or more and less than 6 cranes may be arrange | positioned, or 7 or more cranes may be arrange | positioned.

  A configuration example of the crane 5 will be described. The crane 5 includes, for example, a lower traveling body 51, an upper turning body 52, a cab 53, a boom 54, a wire 55, and a hook 56. The lower traveling body 51 travels by a traveling mechanism such as a crawler or a wheel. The upper turning body 52 is provided on the lower traveling body 51 so as to be turnable, and rotates according to a driving force of a hydraulic motor or the like. A rotation center of the upper swing body 52 is shown as a swing center 50.

  An operator gets in the cab 53 and operates an operation lever (not shown). The boom 54 is rotatably provided in front of the upper swing body 52, and a hook 56 is attached to the tip of the boom 54 via a wire 55. A building structure and equipment are detachably attached to the hook 56. The operator turns the upper swing body 52 in a desired direction, rotates the boom 54 to a desired angle, and moves the hook 56 up and down via the wire 55. Thereby, the operator can carry in the import object, such as a building structure and an apparatus, to the predetermined place of the predetermined height by the crane 5.

  FIG. 7 shows the relationship between the crane work area WZ and the object 7 to be loaded. Which crane 7 is to be assigned to which delivery object 7 will be described later with reference to FIG. Here, the relationship between the crane work area WZ and the carry-in object 7 will be briefly described. Note that there is no direct relationship between the numbers in parentheses in FIG. 6 and the numbers in parentheses in FIG. The same applies to other figures, and the numbers in parentheses are used for explanation in the figures. In FIG. 7, although the crane does not appear directly, the crane having the turning center 50 (1) is called the crane 5 (1), and the crane having the other turning center 50 (2) is called the crane 5 (2).

  Since a certain carry-in object 7 (1) is located only in the work area WZ1 of a certain crane 5 (1), the carry-in object 7 (1) is carried into the building 6 only by the crane 5 (1). I can't do it. Similarly, since the other object 7 (2) is located only in the work area WZ2 of the other crane 5 (2), the object 7 (2) is constructed only by the other crane 5 (2). It cannot be carried into the item 6.

  Another carry-in object 7 (3) is located in a region where the work area WZ1 of the crane 5 (1) and the work area WZ2 of the crane 5 (2) overlap. Therefore, the carry-in object 7 (3) can be carried in either the crane 5 (1) or the crane 5 (2). The carry-in object 7 (3) is composed of a plurality of objects 70 (1) and 70 (2). Therefore, logically, one object 70 (1) constituting the carry-in object 7 (3) is carried in by one crane 5 (1), and the other object constituting the carry-in object 7 (3). It is also possible to make a plan to carry the object 70 (2) with the other crane 5 (2). However, in actuality, since the object 7 (3) to be brought in is physically a group of objects, it is not carried separately by the object unit, and any crane 5 as a whole of the object 7 (3) to be brought in. It carries in to building 6. At the stage of logically calculating the amount of material to be carried in, assignment can be made for each object, and in the final assignment (carrying material mapping), adjustment can be made so that an excessive load is not applied to a specific crane.

  [Crane carry-in mapping unit 112]

  FIG. 8 is a flowchart showing the processing executed by the crane carry-in mapping unit 112. The crane carry-in object mapping unit 112 calculates a carry-in object (equipment or building structure) that can be carried into each crane. It is determined by interference check etc. which crane's work area each loaded object is included in.

  The relationship between each object to be carried in and the work radius of the crane has been described with reference to FIGS. 6 and 7, but will be further described with reference to FIG. FIG. 9 schematically shows a longitudinal section of the building 6. Generally, the building 6 is provided with walls on each of four surrounding surfaces. For convenience of explanation, FIG. 9 illustrates one wall 62 on each side.

  Walls 62 (1) and 62 (2) are vertically provided on both sides of the floor 61 (1) on the first floor. A ceiling (or floor on the second floor) 61 (2) on the first floor is provided at the upper end of the walls 62 (1) and 62 (2) on the first floor. The walls 62 (3) and 62 (4) are provided on both sides of the floor 61 (2) on the second floor. A ceiling (or floor on the third floor) 61 (3) on the second floor is provided at the upper end of the walls 62 (3) and 62 (4) on the second floor. Walls 62 (5) and 62 (6) are provided on both sides of the floor 61 (3) on the third floor. Similarly, for the building 6, the floor (or ceiling) and the wall as the building structure are constructed alternately.

  And according to construction of the building 6, apparatus 7 (1) -7 (3) is carried in and attached to the predetermined position of a predetermined floor. In the example of FIG. 9, the device 7 (1) is placed on the floor 61 (1) on the first floor, the device 7 (2) is placed on the floor 61 (2) on the second floor, and the device 7 (2) is placed on the floor 61 (3) on the third floor. 3) are installed respectively.

  Here, the range in which the boom 54 of the crane 5 shown in FIG. 9 reaches is the work area WZ of the crane 5. Since the devices 7 (1) and 7 (3) are located in the work area WZ of the crane 5, a plan for carrying in with the crane 5 can be made. Since the equipment 7 (2) on the second floor is out of the work area WZ of the crane 5, it is carried in by another crane not shown.

  Returning to FIG. The crane carry-in mapping unit 112 selects any one of the crane work area WZ models created by the crane work area model generation unit 111 as a crane work area model to be processed (S20).

  The crane load mapping unit 112 checks for interference between the crane work area model selected in step S20 and the plant 3D model (S21). For the interference check, a function of general 3DCAD may be used, or an axis parallel bounding box that is generally used as a simple interference check method may be used.

  As shown in FIG. 10, the axis parallel bounding box 71 is the smallest rectangular parallelepiped covering the 3D object 70, and each side is parallel to one of the X axis, the Y axis, and the Z axis. By using this feature, interference can be easily checked as shown in FIG.

  For example, as shown in FIG. 11A, two axis parallel bounding boxes 71 (1) and 71 (2) physically interfere with each other. In FIG. 11, the axis parallel bounding box 71 (1) is shown as BOX1, and the axis parallel bounding box 71 (2) is shown as BOX2.

  In order to detect interference between the axis parallel bounding boxes, as shown in FIGS. 11B and 11C, the magnitudes of the end point coordinates of the two axis parallel bounding boxes are compared on the XY plane and the XZ plane. .

  Here, the X-axis end coordinates of one axis parallel bounding box 71 (1) are X11 and X12, and the X-axis end coordinates of the other axis parallel bounding box 71 (2) are X21 and X22. The Y-axis end coordinates of one axis parallel bounding box 71 (1) are Y11 and Y12, and the Y-axis end coordinates of the other axis parallel bounding box 71 (2) are Y21 and Y22. The Z-axis end coordinates of one axis parallel bounding box 71 (1) are Z11, Z12, and the Z-axis end coordinates of the other axis parallel bounding box 71 (2) are Z21, Z22.

  In this case, since Y11 <Y22 <Y12 and Z21 <Z11 <Z22 are established, it can be seen that an interference region exists between the two axis-parallel boundary boxes 71 (1) and 71 (2).

  Instead of the above-described interference check, whether or not the distance between the coordinates of the crane and the center coordinate of the object 70 of each object 7 is equal to or less than the working radius WD may be used as a criterion for examining the presence or absence of interference. Good.

  Returning to FIG. The crane carry-in mapping unit 112 confirms the presence or absence of interference based on the result of the interference check in step S21 (S22). When it is determined that there is interference (S22: YES), the calculation result storage unit 115 sets the combination of the object IDs of the objects that interfere with each other (the object in the crane work area WZ and the object 7 to be loaded in the plant 3D model). (S23).

  Then, the crane carry-in mapping unit 112 determines whether or not all crane work area models have been inspected for interference (S24). When there is a crane work area model that has not been checked for the presence or absence of interference (S24: YES), the crane load mapping unit 112 determines that there is an unprocessed crane work model that has not executed steps S20 to S22. If so, the process returns to step S20.

  [Carry-in period calculator 113]

  FIG. 12 is a flowchart showing processing executed by the carry-in period calculation unit 113. The carry-in period calculation unit 113 calculates when each carry-in object 7 is carried in. In a large-scale plant, equipment and piping are large, and it may be difficult to carry in from the carry-in entrance after the building construction. In this case, before constructing the ceiling of each floor, there is a case where the crane 5 is used to hang a large carrying object 7 from above. In this case, since the positional relationship between each import object 7 and the ceiling is important, the import period calculation unit 113 calculates the positional relationship between the import object and the ceiling.

  The carry-in period calculation unit 113 determines, for each 3D object of the carry-in object 7 included in the plant 3D model, a 3D object on the ceiling that is directly above the object (FIG. 9 objects 61 (1) to 61 (3). Reference: hereinafter referred to as the ceiling object 61).

  Whether or not a ceiling object exists immediately above the object to be carried in can be calculated by comparing the XYZ coordinates of the axis parallel bounding box of the 3D object, as described in the crane carry-in object mapping unit 112. .

  Specifically, the axis parallel bounding boxes of the ceiling object and the import target object interfere with each other on the XY plane, and the Z coordinate of the upper end of the axis parallel bounding box of the import target object is the axis of the ceiling object. The closest object below the Z coordinate at the lower end of the parallel bounding box is the ceiling object directly above the object to be carried in.

  By extracting the ceiling object directly above the import object, it is possible to determine which import object needs to be carried in before each ceiling is built. In other words, it becomes possible to derive the completion date of delivery of each delivery object. As the determination result, the carry-in period calculation unit 113 stores the combination of the object ID of the carry-in target object and the object ID of the ceiling object in the calculation result storage unit 115.

  The carry-in period calculation unit 113 calculates the connection relationship between the ceiling and wall objects among the 3D objects of the chassis, and stores them in the calculation result storage unit 105 (S31). This is to determine the start date of the carry-in process. As described above, the work for carrying in the object to be carried in is necessary after the construction of the wall and before the construction of the ceiling. Therefore, the order relationship between the wall work process and the ceiling work process is important. If the work process of the wall building and the work process of the ceiling building are not connected in the preceding and succeeding relationship as in the network process, the connection relationship is calculated using the arrangement relationship of the 3D objects.

  For the calculation of the connection relationship, the axis parallel bounding box can be used as described in step S30. However, depending on how to create a ceiling object (floor object), there are two patterns of determination methods as shown in FIG.

  In the first pattern, as shown in FIG. 13A, the ceiling object 61 (1) is placed on the wall objects 62 (1) and 62 (2). In the second pattern, as shown in FIG. 13B, the ceiling object 61 (2) is connected to the upper side of the wall objects 62 (3) and 62 (4).

  In the case of the first pattern, interference on the X and Y coordinates and the Z coordinate with respect to the axis parallel bounding box of the wall objects 62 (1) and 62 (2) and the axis parallel bounding box of the ceiling object 61 (1). Judgment of contact on the top. When the end point coordinates match or when the difference between the end point coordinates is small, it can be determined that they are in contact.

  In the case of the second pattern, the contact on the X coordinate and the Y coordinate and the interference on the Z coordinate are checked with respect to the axis parallel bounding box of the wall object and the axis parallel bounding box of the ceiling object. As the calculation result, the combination of the object ID of the wall object and the object ID of the ceiling object is stored in the calculation result storage unit 115.

  Returning to FIG. The carry-in period calculation unit 113 reads the work start date and work completion date of each ceiling and wall from the building process database 3 (S32). Then, the carry-in period calculation unit 113 can carry in each carry-in object using the relationship between the carry-in object object and the ceiling object, the connection relation between the wall object and the ceiling object, the work start date, and the work completion date. The period is calculated (S33). The period during which the object to be loaded can be loaded may be referred to as a loading period.

  As shown in FIG. 14A, consider a state in which the object 7 to be brought in is surrounded by a frame object such as a wall 62 (1), a wall 61 (2), and a ceiling 61 (2). In this case, after the construction of the wall 62 (1) and the wall 62 (2) is completed and before the construction of the ceiling 61 (2) is started, it is necessary to carry in the import object 7. Therefore, the period during which the object 7 can be carried in can be created as the period from the construction completion date of the wall 62 (2) to the construction start date of the ceiling 61 (2), as shown in FIG. 14 (b). it can. The loading period may be defined by designating the start time and the end time as described above. Instead, for example, the loading object 7 is loaded after a certain period from the construction completion date of the wall 62 (2). It may be defined as starting or completing the loading of the loading object 7 by a predetermined period before the construction start date of the ceiling 61 (2).

  In step S <b> 33 of FIG. 12, the carry-in period calculation unit 113 calculates the carry-in start date and the carry-in completion date for all the carry-in objects, and stores the results in the calculation result storage unit 115.

  [Crane usage time calculation unit 114]

  FIG. 7 is a flowchart of processing executed by the crane usage time calculation unit 114. The crane usage time calculation unit 114 calculates the amount of the object to be carried in with respect to the object to be carried in (S40) because the object to be carried in such as a building structure or equipment is not necessarily generated in the unit of carrying in. .

  A case where one device is carried in by one carrying-in operation will be described. In general, since one device is composed of a plurality of (N) objects, N objects are loaded in one loading operation. Therefore, it is considered that the amount of carry-in corresponding to one object constituting the device is less than 1 (for example, 1 / N), or one of N objects is set as the carry-in amount 1 and the other ( N-1) It is necessary to calculate the amount of carry-in with the amount of carry-in of objects as zero.

  Similarly, in the case of pipes, they are welded in units called pipe spools at the manufacturing plant, transported to the construction site, and carried in. When the piping object is generated in a unit smaller than the piping spool, one piping spool is constituted by a plurality of piping objects, and the amount of carry-in corresponding to one piping object is less than 1. For example, when one piping spool is constituted by five piping objects, the amount of carry-in corresponding to one piping object is 1/5 = 0.2. If there is a correspondence between the piping objects and the piping spools, the amount of incoming material may be set to 1 / N for each of the N piping objects constituting each piping spool. On the other hand, if the design is not sufficiently advanced at the early stage of the project and there is no correspondence between the piping object and the piping spool, the average spool length is defined based on the past project results, etc. The amount of incoming goods can be calculated by dividing the length of the object by the average spool length.

  The crane usage time calculation unit 114 reads the carry-in start date and the carry-in completion date for each carry-in object object calculated by the carry-in period calculation unit 113 from the calculation result storage unit 115 (S41), and per unit time for each carry-in object object. Is calculated (S42).

  For example, a case will be described in which a certain pipe object has a carry-in amount of 1.5, a carry-in start date is April 1, a carry-in completion date is April 5, and a carry-in date is five days. Divide 1.5 by 5 days if the unit time is a day. It will be calculated to carry 0.3 bottles per day. The crane usage time calculation unit 114 stores the calculation result in the calculation result storage unit 115.

  The crane usage time calculation unit 114 calculates the crane usage time per unit time from the amount of the incoming goods per unit time for each object to be carried in (S43). It can be calculated by defining the crane usage time per piece of equipment in advance. The crane usage time calculation unit 114 stores the calculation result of the crane usage time per unit time in the calculation result storage unit 115. In addition, when there is no crane usage time per physical quantity, step S43 does not need to be performed. In that case, the final output result is not a value obtained by piled up the usage time for each crane but a value obtained by piled up the amount of carry-in for each crane.

  The crane usage time calculation unit 114 calculates the usage time in each unit time zone for each crane (S44). For the calculation in step S44, the calculation result in step S43 and the calculation result in the crane load mapping unit 112 are used.

  For example, as shown in a table T10 in FIG. 14A, the crane start time per unit time (here, day), the import start date of the import object A is April 2 and the import completion date is April 4. Is 0.3 hours / day, and the crane that can be carried in is Crane A. Similarly, the carry-in object B has a carry-in start date of April 3, a carry-in completion date of April 5, a crane usage time per unit time of 1.0 hour / day, Assume that it is crane A.

  Then, as shown in the table T11 of FIG. 14B, the pile value of the crane usage time is updated. First, the table T11 (1) of the first step shows a pile of crane usage hours in the initial state, and the usage hours are zero in all time zones of all cranes.

  The second step table T11 (2) represents a state in which the crane usage time of the object A is added. Specifically, the crane usage time per unit time (0.3 hours / day) for each day from the import start date (April 2) to the completion date (April 4) of object A Is added.

  The table T11 (3) of the third step represents a state in which the crane usage time of the object B is added as in the second step. The crane usage time for April 3 and April 4 is 1.3 hours / day, which is 0.3 hours / day for object A and 1.0 hours / day for object B. In this way, the crane usage time is added to all the objects to be carried in.

  However, when a single object to be carried can be carried by a plurality of (N) cranes, the crane usage time may be equally distributed (1 / N) to each crane. Or the method of selecting any one crane and adding use time can be considered. In the latter case, a crane closest to the object A may be selected, or a crane having the least usage time may be selected within the loading period of the object A in the temporary crane usage time pile at the time of calculation. . Any method may be adopted.

  Although not shown in FIG. 17, as described above, the crane usage time display unit GA11, the bird's eye view display unit GA12, and the top view display unit GA12 display the same crane name associated with the same crane. ing. And each crane of each display part GA11-GA12 has cooperated through the crane name, and if a user selects a desired crane in any display part, the crane name same as the selected crane name will be matched. Information about the crane in question is highlighted on all other displays. The highlighting method may be, for example, highlight display or blinking display.

  FIG. 18 is an example of a carry-in quantity display unit G20 for displaying a quantity of equipment to be carried by each crane, a device list, and the like. This screen G20 includes, for example, a crane name, a logical quantity, a physical quantity, a 3D object list, and an actual equipment list.

  The crane name is information for identifying each crane 5 by the construction plan support apparatus 1. The logical quantity is the number of 3D objects assigned to the crane. The physical quantity is the number of equipment actually carried in by the crane. Since an actual device is formed from a plurality of 3D objects, the actual physical quantity is smaller than the logical quantity.

  The 3D object list is a list of 3D objects assigned to the crane. The actual equipment list is a list of equipment assigned to the crane. The equipment here includes piping. It can display similarly about a building structure. The logical quantity and the 3D object list can be omitted. The screen shown in FIG. 18 may be displayed as a part of the screen G10 shown in FIG. 17 or a screen G20 described later in FIG. 19, or may be displayed as a separate screen.

  By operating the animation control button B21, the user can control the playback state of the animation such as playback, stop, and reverse playback. When playback is started, the time in the animation elapses, and the display form of the crane 3D model display unit GA22 changes according to the crane usage time in each unit time zone.

  For example, the display color of the crane 3D model is defined in advance such as red when the crane usage time per unit time is 120 hours or more, yellow when it is 60 hours or more and less than 120 hours, blue when it is less than 60 hours, etc. The crane 3D model is colored according to the amount of use time in a certain unit time zone (month).

  According to the present embodiment configured as described above, it is possible to calculate the amount of use for using each crane 5 to carry in the carry-in object 7. Therefore, it is possible to support the creation of an appropriate construction plan by suppressing the creation of an unreasonable plan in which each crane 5 is excessively used.
