   The present invention relates to a device arrangement design support apparatus, a device arrangement design support method, and a program.

  Development of technology to support equipment layout design in the plant is underway. For example, Patent Document 1 discloses a device placement system that generates an optimal device placement plan that satisfies the constraints on the device layout. This device placement system sets a placement reference point on the placement space based on pre-registered constraints such as the physical conditions of the device, the relative positional relationship of the devices, and the shape of the placement space. The device is arranged vertically and horizontally based on the point to search for the optimum arrangement position.

  However, the apparatus arrangement system disclosed in Patent Document 1 is based on the premise that an apparatus is installed on a floor surface that is one of defining surfaces that define an arrangement space or a plane parallel to the floor surface. Therefore, for example, when the placement reference point is close to the wall surface of the placement space and the device cannot be placed on the floor surface or a plane parallel to the floor surface due to physical interference with the wall surface, the placement reference point is the wall surface. The device is placed on a floor surface that does not interfere with the wall surface or a plane parallel to the floor surface. As described above, the device arrangement system disclosed in Patent Document 1 is arranged on the floor surface or a plane parallel to the floor surface even if the device can be attached to the wall surface or the ceiling surface. It is difficult to design the layout of the equipment used.

  The present invention has been made in view of the circumstances as described above, and effectively utilizes an arrangement space and can appropriately support the arrangement design of an apparatus, an apparatus arrangement design support apparatus, an apparatus arrangement design support method, and The purpose is to provide a program.

The registration means includes arrangement space information including arrangement constraint conditions that are restrictions on arrangement of equipment in the arrangement space, information indicating a demarcation plane that demarcates the arrangement space, and installation conditions of the apparatus for each of the demarcation planes. Register device information. The device arrangement design means searches for an arrangement position satisfying the arrangement constraint condition and the installation condition, and designs the arrangement of the equipment in the arrangement space. The output means outputs a design result by the device arrangement design means.

  According to the present invention, the device arrangement design support device includes arrangement space information including information indicating a restriction surface that is a restriction condition for placing a device in the arrangement space and a demarcation surface that demarcates the arrangement space. The device information including the device installation conditions for each is registered, the placement constraints satisfying the placement constraint conditions and the installation conditions are searched, the device placement in the placement space is designed, and the design result is output. For this reason, according to this invention, arrangement | positioning space can be utilized effectively and arrangement | positioning design of an apparatus can be supported appropriately.

  Hereinafter, a device arrangement design support apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the device arrangement design support apparatus 100 according to the embodiment of the present invention includes a control unit 110, a storage unit 120, an input unit 130, and an output unit 140. Each of these components is electrically connected to each other via a bus line BL.

  The control unit 110 includes, for example, a computer having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like, and the CPU reads various operation programs stored in the ROM and stores them on the RAM. By executing the above, each component of the device arrangement design support apparatus 100 is controlled. The control unit 110 functionally includes an input / output data control unit 111 and a device arrangement design unit 112.

  The input / output data control unit 111 controls data input by the input unit 130 described later and data output by the output unit 140. For example, the input / output data control unit 111 stores the arrangement space information and the device information input by the input unit 130 by a user operation in the arrangement space information DB 121 and the device information DB 122 of the storage unit 120, and updates / registers each information. To do. At this time, the input / output data control unit 111 appropriately converts the configuration space information, the shape data included in the device information, the coordinate data, and the like into a three-dimensional CAD data format and stores the data. In addition, the input / output data control unit 111 controls the output unit 140 to output a CAD image based on the three-dimensional CAD data included in the arrangement space information, device information, arrangement design information, and the like. The input / output data control unit 111 functions as a registration unit together with the storage unit 120 described later.

  The device arrangement design unit 112 searches for the optimum arrangement position of the devices arranged in the arrangement space based on the arrangement space information and device information registered in advance by the user, and outputs the search result as arrangement design information. The arrangement design information includes at least coordinate data of the arrangement position in the arrangement space coordinate system. When searching for the optimum arrangement position, the device arrangement design unit 112 sequentially searches for an arrangement position that satisfies the arrangement constraint condition included in the arrangement space information and the installation condition included in the apparatus information.

  The device arrangement design unit 112 uses, for example, a genetic algorithm which is a kind of optimization algorithm. By using a genetic algorithm, a plurality of device placement plans that are candidate solutions are generated, and a new device placement plan is generated from the existing device placement plan by operations such as crossover and mutation. Based on the above, the device arrangement plan is selected, and the generation change is repeated to search for the optimum device arrangement plan. It should be noted that various algorithms other than the genetic algorithm can be used as a method for searching for the optimum arrangement position of the device. The device arrangement design unit 112 functions as a device arrangement design unit.

Examples of the arrangement constraint conditions in the arrangement space include the following items.
(A) Does not interfere with building structures and equipment in the arrangement space (b) Does not interfere with each other (c) Shortens the piping path connecting the devices (d) Increases the distance between the devices

  The above (c) is a condition provided from the viewpoint of economy, and (d) is a condition provided from the viewpoint of equipment maintenance management. As described above, the placement constraint condition may include a condition having a trade-off relationship.

Moreover, the following items are mentioned as an installation condition of an apparatus, for example.
(E) Restriction of installation direction and installation angle of equipment (f) Restriction of definition surface to be installed (g) Restriction of relative position with other equipment (h) Restriction of introduction cost and operation cost

  The storage unit 120 includes a nonvolatile storage device that can rewrite storage contents such as an HDD (Hard Disk Drive), an SSD (Solid State Dive), and the like. For example, the control unit 110 executes each process based on an operation program. Various data to be read and referred to at this time are stored.

  The storage unit 120 includes a plurality of databases that store various data. Hereinafter, the database may be referred to as “DB” (Data Base). The storage unit 120 includes, for example, a placement space information DB 121 that stores placement space information related to a partitioned placement space in a building, a device information DB 122 that stores device information related to devices, and a placement design information DB 123.

  The arrangement space information DB 121 stores the arrangement space information, for example, in the form of an arrangement space information table shown in FIG. In the arrangement space information table, data of each item of “space ID”, “space size”, and “placement prohibited space” is associated. The “space ID” is identification information set in advance in the arrangement space in the building. The “space size” is a dimension of the arrangement space, and the numeric values of the width W, the depth D, and the height H are stored in the arrangement space information table. The “arrangement prohibition space” is a space in which new arrangement of devices in the arrangement space is restricted, such as a space where devices are already arranged, a space occupied by building structures such as pillars and partition walls. In the placement space information table, a vertex coordinate data group is stored for each placement prohibited space as data indicating “placement prohibited space”, and a space surrounded by connecting a plurality of vertex coordinates with a straight line is defined as a placement prohibited space. Defined.

  The device information DB 122 stores device information, for example, in the format of a device information table shown in FIG. The device information table correlates data of each item of “device ID”, “shape”, “outside size”, “weight”, “installation condition”, “performance specification”, “introduction cost”, and “operation cost”. It has been. The “device ID” is device identification information, and the “shape” is an external shape of the device. “Outer size” is the outer size of the device, and the device information table stores numerical values of width W, depth D, and height H. The “installation condition” is a condition for placing the device in the placement space, and is set in consideration of efficiency of wiring connection with other devices, operation convenience, and the like. For example, in the device information table, as the installation condition of the device ID “X001”, “landscape: impossible, wall / ceiling: impossible, proximity to device X007”, etc. are set. However, it is recommended that it be installed close to the device X007. The “performance specification” stores performance data based on various performance evaluation indexes. The “introduction cost” and “operation cost” are expenses required for introducing and operating the device. In general, among devices having equivalent performance, a device having a small outer size, that is, a device that is reduced in size tends to be expensive.

  The layout design information DB 123 stores the layout design information, for example, in the form of a layout design information table shown in FIG. In the layout design information table, data of each item of “space ID”, “arranged device ID”, “installation direction”, “installation surface”, and “arrangement position” is associated. The “placed device ID” is identification information set in advance for a device placed in the placement space. “Installation direction” and “installation surface” indicate in what orientation and on which definition surface the devices arranged in the arrangement space are installed. Note that the installation surface and the installation direction of the device are determined so as to satisfy the installation conditions included in the device information. In addition, the “installation direction” includes an installation angle indicating an angle at which the device is installed on the installation surface, in addition to whether the device is vertically or horizontally. “Arrangement position” indicates the position of the device arranged in the arrangement space. The “arrangement position” is represented, for example, by a coordinate value in a three-dimensional orthogonal coordinate system set with reference to a demarcation plane on which the device is installed. Note that the “arrangement position” may be represented in a unified manner using coordinate values in a three-dimensional orthogonal coordinate system set with reference to one specified plane of the arrangement space. Further, the coordinate value indicating the arrangement position in the arrangement space may be a coordinate value of each vertex of the device, or may be a coordinate value of a plurality of representative points of the device.

  Returning to FIG. 1, the input unit 130 includes input devices such as a keyboard, a mouse, a touch panel, and operation buttons, and receives various user operations. The input unit 130 receives, for example, input of arrangement space information and device information by the user.

  The output unit 140 includes a display device such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), and an organic EL (Electro-Luminescence) display, and an output device such as a printing device. The contents of the information are presented to the user by displaying images and printing them out. Thus, the input unit 130 and the output unit 140 are interfaces for exchanging information between the layout design support apparatus 100 and the user. The output unit 140 functions as an output unit.

  Next, a device arrangement design process executed by the device arrangement design support apparatus 100 will be described with reference to the flowchart shown in FIG. The device arrangement design process is a process of searching for an optimum arrangement position of the device in the arrangement space and outputting a search result.

  The control unit 110 starts the device arrangement design process in response to the activation of the software for performing the arrangement design installed in the device arrangement design support apparatus 100. When the device arrangement design process is started, the control unit 110 first determines whether or not an arrangement space for designing the arrangement of devices has been selected (step S101). The control unit 110 determines whether or not the input unit 130 has received an arrangement space selection operation by the user. When it is determined that the arrangement space is not selected (step S101: NO), the control unit 110 repeats the process of step S101 and waits until the arrangement space is selected.

  On the other hand, when it is determined that the arrangement space has been selected (step S101: YES), the control unit 110 arranges the arrangement space information stored in the arrangement space information DB 121 of the storage unit 120 and the arrangement design information stored in the arrangement design information DB 123. (Step S102), and the output unit 140 is controlled to display a three-dimensional CAD image depicting the arrangement state of the selected arrangement space on the CAD space (step S103).

  Here, with reference to FIG. 6, an example of a pseudo arrangement space obtained by modeling an actual arrangement space will be described. The pseudo arrangement space PS shown in FIG. 6 has a substantially cubic shape, and is defined by six surfaces: a floor surface SD, a ceiling surface SU, a front wall surface SF, a rear wall surface SB, a right wall surface SR, and a left wall surface SL. The pseudo arrangement space PS is modeled based on the arrangement space information stored in the arrangement space information DB 121 of the storage unit 120 and displayed as a three-dimensional CAD image. For example, when the device is placed on the floor surface SD, the placement position of the device placed in the pseudo placement space PS is represented by a coordinate value in an XYZ orthogonal coordinate system set based on the floor surface SD. Is installed on the right wall surface SR, it is represented by a coordinate value in the UVW orthogonal coordinate system set on the basis of the right wall surface SR.

  FIG. 7 shows a state in which a plurality of devices are arranged in the pseudo arrangement space PS. In the pseudo arrangement space PS shown in FIG. 7, the devices A1, A2, and A3 are arranged based on the arrangement design information stored in the arrangement design information DB 123 of the storage unit 120.

  Subsequently, the control unit 110 determines whether or not a device to be newly placed has been selected (step S104). The control unit 110 determines whether or not the input unit 130 has received a device selection operation by the user. When it is determined that no device is selected (step S104: NO), the control unit 110 repeats the process of step S104 and waits until a device is selected.

  On the other hand, when it determines with the apparatus having been selected (step S104: YES), the control part 110 performs an optimization process (step S105). The optimization process is a process for searching for an optimal arrangement position of the device in the arrangement space. In the optimization process, for example, a genetic algorithm is used. At the end of the optimization process, the control unit 110 outputs the search result as layout design information.

  In the pseudo arrangement space PS shown in FIG. 7, there is a device B1 selected by the user as a device to be arranged in step S104. In the optimization process, the optimal arrangement position of the device B1 is searched by a genetic algorithm. Here, in the process of optimizing the arrangement position by the genetic algorithm, it is assumed that a device arrangement plan to be installed on the right wall surface SR is generated as a candidate for the arrangement position of the apparatus B1.

  FIG. 8 is a cross-sectional view taken along a plane PL parallel to the front wall surface SF of the pseudo arrangement space PS in FIG. As shown in FIG. 8, the cross section PSS of the pseudo arrangement space PS is divided into meshes, the mesh corresponding to the cross section of the device A1 is set as the device cross sectional area AA1, and the mesh corresponding to the cross section of the device A2 is set as the device cross sectional area AA2. It is hatched with a diagonal line in the downward direction. The mesh corresponding to the cross section of the device B1 arranged in the pseudo arrangement space PS is hatched with a diagonal line in the upward direction as the device cross-sectional area BB1. Furthermore, the upper two meshes of the cross section PSS are a placement prohibition area PA, which is a region where placement of devices is restricted, and is set based on the placement prohibition space included in the placement space information. Note that the size of the mesh is preferably equal to or smaller than the size of the device having the minimum external size registered in the device information DB 122.

  Here, the device cross-sectional area AA2 and the device cross-sectional area BB1 partially interfere with each other, and there is an interference area AB hatched with diagonal lines in two directions. For this reason, since the device B1 does not satisfy the placement constraint condition, this device placement plan is deceived in the genetic algorithm.

  On the other hand, when the device B1 is rotated, for example, 90 degrees in the direction around the W axis shown in FIG. 6, as shown in FIG. 9, the device cross-sectional area AA2 and the device cross-sectional area BB1X do not overlap, and the device B1 Can be installed on the right wall SR without interfering with the device A2.

  In consideration of the external size, performance specification data, introduction cost, and operation cost included in the device information, the device B1 is replaced with a device B2 having the same performance and having a smaller external size than the device B1. Even when it is arranged in the arrangement space, there is a possibility that it can be installed on the right wall surface SR without interfering with the device A2. The device B2 corresponds to a second device that is replaced with the device B1 that was originally planned to be placed. In this case, the user may change the device to be arranged in the arrangement space from the device B1 to the device B2, and execute the device arrangement design process.

  Returning to the description of the flowchart of the device arrangement design process shown in FIG. 5, after executing the optimization process in step S105, the arrangement state of the arrangement space in which the apparatus selected in step S104 is arranged based on the arrangement design information. A three-dimensional CAD image drawn on the CAD space is displayed (step S106). Thereby, the user can confirm the arrangement state of the devices in the arrangement space on the three-dimensional space, and can edit the three-dimensional CAD data as appropriate.

  After executing the process of step S106, the control unit 110 ends the device arrangement design process.

  As described above, the device arrangement design support apparatus 100 according to the present embodiment has the arrangement constraint condition that is a restriction condition for arranging the device in the arrangement space, the floor surface SD that defines the arrangement space, and the ceiling surface. Register arrangement space information including information representing demarcated surfaces such as SU, front wall surface SF, rear wall surface SB, right wall surface SR, and left wall surface SL, and device information including device installation conditions for each of the demarcation surfaces. The optimal arrangement position of the equipment satisfying the installation constraint condition included in the information and the installation condition included in the equipment information is searched, and the search result is output as the layout design information. Thereby, according to the device arrangement design support apparatus 100, the arrangement space can be effectively used, and the arrangement design of the device can be appropriately supported.

  The device arrangement design support apparatus 100 optimizes the arrangement position of the device in the arrangement space using an optimization algorithm such as a genetic algorithm. The device arrangement design support apparatus 100 is a second device that can be replaced with a device from the viewpoint of performance when the device to be arranged in the arrangement space interferes with the arranged device, and has a smaller outer size than the device. Can be arranged in the arrangement space, and the devices arranged in the arrangement space can also be arranged by rotating in three axial directions orthogonal to each other.

  In addition, the device arrangement design support apparatus 100 can arrange other devices that can replace the device arranged in the arrangement space in the arrangement space in consideration of the introduction cost, the operation cost, and the like.

  As shown in FIG. 8, the device arrangement design unit 112 estimates the cost required for replacing the device B1 that interferes with the device A2 with another replaceable device from the introduction cost and the operation cost included in the device information. It may be calculated and output as an evaluation value. The user can adjust the balance between the external size of the device and the cost by adopting the evaluation value as an evaluation index in the genetic algorithm.

  In the above embodiment, the operation program executed by the CPU included in the control unit 110 is stored in advance in the ROM. However, the present invention is not limited to this, and an apparatus according to the above-described embodiment is implemented by mounting an operation program for executing the above-described various processes on an existing general-purpose computer, framework, workstation, or the like. You may make it function as an apparatus equivalent to the arrangement | positioning design support apparatus 100. FIG.
