Description

The present specification supports instrumentation design that determines the configuration required for automatic control of the instrumentation equipment based on a basic instrumentation diagram including an instrumentation component and a connection line connected to the instrumentation component. Disclose the instrumentation design support device.

Various facilities are provided in facilities such as buildings and plants. For example, buildings are equipped with equipment related to air conditioning, water supply and drainage, electricity, and lighting. In addition, the plant is equipped with production equipment and management equipment. When designing facilities such as buildings and plants, it is necessary to determine the layout of these various types of equipment.

Furthermore, when designing such a facility, instrumentation design is also performed to measure the state of various facilities installed in the facility and determine the configuration for automatically controlling the facilities according to the measurement results. In instrumentation design, usually, the control item to be implemented is determined for each equipment (instrumentation equipment) subject to automatic control, and the parts (instrumentation parts) necessary for implementing this control item are selected. Further, in the instrumentation design, a diagram showing the connection relationship between the selected instrumentation parts and the instrumentation equipment, that is, a so-called instrumentation diagram is generated. Based on this generated instrumentation diagram, instrumentation parts are installed and maintained.

However, conventionally, in order to perform such instrumentation design, the designer has required abundant experience and knowledge. Moreover, even a designer with sufficient experience and knowledge has trouble designing instrumentation for a plurality of facilities.

Japanese Unexamined Patent Publication No. 2008-192009 Japanese Unexamined Patent Publication No. 11-338903

Here, many techniques for reducing the burden on the designer in such facility design have been conventionally proposed. For example, Patent Document 1 discloses a control point data automatic generation device that automatically generates control point data. The control point data is data input to the central monitoring control device that is responsible for automatic control of the control equipment. In order to automatically generate this control point data, Patent Document 1 provides a case database for storing instrumentation diagram data and control point data related to a plurality of past cases, and searches and selects a similar past case database. Acquire the instrumentation diagram data and control point data of the matter, and generate the control point data of the current matter based on the data of this similar past matter.

Further, Patent Document 2 discloses a technique for creating a list of device data from P & ID data. The P & ID data is data showing a system diagram of plant equipment and instrumentation, and is created by CAD. In Patent Document 2, predetermined graphic information, character string information, and line segment information are extracted from the P & ID data, and a list of equipment data for a plant inherent in the P & ID data is created based on the extracted information. ..

According to such a technique, the burden of facility design can be reduced to some extent. However, both Patent Documents 1 and 2 assume that the instrumentation diagram and the P & ID data itself are created by the designer. However, in order to create an instrumentation drawing, in particular, to select and determine the necessary instrumentation parts, sufficient experience and a lot of labor are required, and the burden on the designer is heavy. With the prior art, the burden of creating such an instrumentation diagram could not be reduced, and as a result, the burden on the designer in the instrumentation design could not be sufficiently reduced.

FIG. 1 is a block diagram showing a physical configuration of the instrumentation design support device 10. Further, FIG. 2 is a functional block diagram of the instrumentation design support device 10.

The instrumentation design support device 10 is a device for supporting instrumentation design in various facilities. Here, the instrumentation design means a design for measuring and controlling the state of various facilities installed in the facility. Such instrumentation design includes, for example, instrumentation design related to air conditioning equipment in a building, instrumentation design related to water supply and drainage equipment in a building, and instrumentation design related to various production equipment and management equipment in an industrial plant. In the following, a support device that supports instrumentation design for air conditioning equipment in a building will be described as an example. However, the technique disclosed in this specification is not limited to building air-conditioning equipment, and may be applied to instrumentation design support for other equipment.

The instrumentation design support device 10 is physically constructed by one or more computers driven according to a specific program. That is, as shown in FIG. 1, the instrumentation design support device 10 includes a CPU 12, a storage device 14, an input device 16, an output device 18, and a communication interface (hereinafter referred to as “communication I / F20”). These are connected by a bus 22.

The CPU 12 performs various operations. Specifically, the CPU 12 reads the design support program stored in the storage device 14 in accordance with the instruction from the operator, and performs various calculations necessary for the design support. The specific contents of the processing by the CPU 12 will be described later.

The storage device 14 stores various data (including programs), and is configured by combining one or more semiconductor memories such as RAM and ROM, a hard disk drive, a solid state drive, and the like. The storage device 14 stores an instrumentation design support program for causing the CPU 12 to execute an instrumentation drawing generation process, a component list 70 generation process, and the like, which will be described later. Further, the storage device 14 also stores data constituting a control item database 44 (hereinafter, “database” is abbreviated as “DB”), a symbol DB 42, and a component DB 46, which will be described later.

The input device 16 receives operation instructions and data input from an operator, and is configured by combining one or more keyboards, mice, touch panels, microphones, scanners for reading drawings printed out on paper, cameras, and the like. .. The output device 18 outputs various information to the operator, and is configured by combining one or more displays, speakers, and the like, for example. Further, although not shown in FIG. 1, the instrumentation design support device 10 may include a printer that prints and outputs necessary information on paper. The communication I / F 20 exchanges data with other information terminals. The additional instrumentation diagram or superimposed diagram generated by the instrumentation design support device 10 may be sent to another information terminal via the communication I / F20.

Although the instrumentation design support device 10 is shown as one computer in FIG. 1, the instrumentation design support device 10 may be composed of a plurality of computers capable of communicating with each other. Therefore, for example, the instrumentation design support device 10 may be composed of a main computer and a tablet terminal capable of communicating with the main computer and used by an operator at a work site. Further, various DBs can communicate with the main computer and may be stored in another computer functioning as a data server.

FIG. 2 is a functional block diagram of the instrumentation design support device 10. The instrumentation design support device 10 adds a first block B1 that generates a basic instrumentation diagram 52 from a plan view 48 and instrumentation parts necessary for automatic control of instrumentation equipment to the basic instrumentation diagram 52. The second block B2 for generating the instrumentation diagram 64, the third block B3 for generating further information using the additional instrumentation diagram 64 and the plan view 48, and the three referred to in the first to third blocks B3. It is roughly classified into a fourth block B4 having two DBs. The functions of the first to third blocks B1 to B3 are realized exclusively by the CPU 12, and the functions of the fourth block B4 are realized exclusively by the storage device 14.

Here, the plan view is a duct and piping for connecting the instrumentation equipment and the instrumentation equipment (hereinafter, “connection line” when the duct and the piping are not distinguished) in the plan layout view of the facility (building in this example). It is an equipment diagram that draws (called). The equipment diagram (plan view) includes an electrical equipment diagram depicting electrical equipment, a water supply / drainage equipment diagram depicting water supply / drainage equipment, an air conditioning equipment diagram depicting air conditioning equipment, etc., but in this example, instrumentation related to air conditioning equipment For the design, treat the air conditioner diagram as a plan view.

Further, the instrumentation equipment is a device whose positional relationship with the spatial layout is important, and is a device that is a target of instrumentation design. In this example, in order to design the instrumentation of the air conditioner, the air conditioner such as an air handling unit (hereinafter referred to as "AHU"), a packaging air conditioner, a cooling tower, and a boiler is the instrumentation equipment. Such instrumentation equipment is drawn on a plan view because the positional relationship with the spatial layout is important.

The basic instrumentation diagram is a diagram showing the connection relationship between the instrumentation equipment and the connection line. In this example, this basic instrumentation drawing is automatically generated from the plan view. In the basic instrumentation drawing, the instrumentation equipment is divided into a plurality of components and drawn as needed. For example, the AHU is drawn as a single element in the plan view, but in the basic instrumentation drawing, the AHU is divided into a plurality of elements such as an air filter, a hot / cold water coil, a humidifier, and a fan that make up the AHU. Is drawn. This is to make it easy to understand the connection relationship between the instrumentation parts and each element, which will be described later.

The additional instrumentation drawing is a drawing in which one or more instrumentation parts necessary for automatic control of the instrumentation equipment are added to the basic instrumentation drawing, and shows the connection relationship between the instrumentation equipment and one or more instrumentation parts. It is a drawing. Here, as described above, the instrumentation parts are the equipment necessary for automatically controlling the instrumentation equipment, and the positional relationship with the spatial layout is not important, and the connection relationship with the instrumentation equipment is exclusively. It is an important device. Instrumentation components include, for example, programmable controllers (hereinafter referred to as "PLCs") that process signals required for control, sensors that detect various physical quantities, actuators that drive each part, valves that open and close the flow path, and electricity. Includes relays that connect / disconnect signals. In the additional instrumentation diagram, the connection relationship between these instrumentation parts and the instrumentation equipment is drawn graphically.

Next, the functional block diagram shown in FIG. 2 will be described with reference to specific examples. The drawing reading unit 24 reads the plan view 48 of the target facility, and converts the plan view 48 into a data format that can be referred to by the facility extraction unit 26 or the like in the subsequent stage. For example, when the plan view 48 is input in a form printed on paper, the drawing reading unit 24 includes a scanner or a camera that reads the plan view 48 of the paper and converts it into digital data. Further, the plan view 48 may be input in the form of digital data such as image data or CAD data. In this case, the drawing reading unit 24 reads the input digital data and, if necessary, a data format. Is converted. Then, the drawing reading unit 24 outputs the plan view data in a desired data format to the line extraction unit 28, the equipment extraction unit 26, and the superimposed figure generation unit 38. Although it is assumed that only the plan view 48 is input to the instrumentation design support device 10 here, various design conditions (for example, air conditioning method, duct size, etc.) may be input together with the plan view 48.

FIG. 3 is an image of the plan view 48. As shown in FIG. 3, in the plan view 48, a figure showing the plane layout, a figure showing the instrumentation equipment (including characters), and a figure showing the ducts and pipes connected to the instrumentation equipment (including characters). ) And is included. The plan view 48 shown in FIG. 3 is significantly simplified as compared with the normal plan view 48 in order to facilitate the explanation. Further, the figure showing the equipment in FIG. 3 is also different from the figure used in the actual plan view 48.

The equipment extraction unit 26 extracts instrumentation equipment from the plan view 48. In this extraction, the equipment extraction unit 26 refers to the symbol DB 42. In the plan view 48, the symbol DB 42 stores a figure indicating instrumentation equipment (hereinafter referred to as “equipment symbol”) and a figure indicating a connection line (hereinafter referred to as “line symbol”). For example, in this example, in the plan view 48, the AHU is represented as a figure in which the characters "AHU" are surrounded by a quadrangle. Further, in the plan view 48, the return air duct is represented as a line with the letters “RA”. In the symbol DB 42, the graphic (equipment symbol) indicating the instrumentation equipment and the graphic (line symbol) indicating the connection line in the plan view 48 are stored in association with the identification information of the corresponding instrumentation equipment and the connection line. There is.

The equipment extraction unit 26 extracts a figure matching the equipment symbol from the input plan view 48 by using a technique such as image matching. This extraction may be performed for all the equipment symbols stored in the symbol DB 42, or may be performed only for the equipment symbols of the group previously designated by the operator. For example, in the air conditioning design of a building, the air conditioning system is determined at a relatively early stage, and the air conditioning equipment that may be used by the air conditioning system is limited to some extent. Therefore, when the operator inputs the air conditioning method as one of the design conditions, only the air conditioning equipment that can be used in the air conditioning method may be limited to the extraction target. With such a configuration, the amount of calculation of the instrumentation design support device 10 can be reduced. If a figure matching the equipment symbol is found in the plan view 48, the equipment extraction unit 26 obtains the identification information of the instrumentation equipment corresponding to the equipment symbol and the drawing position of the figure in the plan view 48. Output to the connection interpretation unit 30.

The line extraction unit 28 extracts connection lines (ducts and pipes) from the plan view 48 by using a technique such as image matching. In this extraction, the line extraction unit 28 refers to the symbol DB 42. If a figure matching the line symbol is found in the plan view 48, the equipment extraction unit 26 further extracts the line connected to the line symbol. Then, if all the line symbols and the lines connected to them can be extracted, the equipment extraction unit 26 connects the identification information of the connection line corresponding to the line symbol and the drawing position of the lines connected to the line symbol in the plan view 48. Output to 30.

The extraction of the connection line may be performed for all the line symbols stored in the symbol DB 42, or may be performed only for the line symbols of the group specified in advance by the operator. Further, at the time of this equipment extraction and line extraction, the result of this extraction may be displayed on a display so that the operator can confirm the quality of the extraction result. For example, the plan view 48 is displayed on the display, and only the instrumentation equipment and the connection line extracted from the plan view 48 are displayed in a special form (for example, highlight display, different color display, marker addition, etc.). You may. Then, if there is an error in the extraction result, the operator may manually correct it.

The connection interpretation unit 30 interprets the connection relationship between the instrumentation equipment and the connection line drawn in the plan view 48 based on the information input from the equipment extraction unit 26 and the line extraction unit 28. For example, when the end of the line indicating one return air duct reaches the equipment symbol indicating AHU, the connection interpretation unit 30 interprets that the return air duct is connected to the AHU. Such an interpretation result is output to the basic instrumentation diagram generation unit 32.

The basic instrumentation diagram generation unit 32 generates a basic instrumentation diagram based on the interpretation result of the connection interpretation unit 30. As described above, the basic instrumentation diagram is a diagrammatic representation of the instrumentation equipment and the connection lines connected to it. FIG. 4 is a diagram showing an example of the basic instrumentation diagram 52. Here, as is clear from FIG. 4, in the basic instrumentation diagram 52, the instrumentation equipment is represented by a figure suitable for the instrumentation diagram. That is, even in the same instrumentation equipment, the figure used in the plan view 48 and the figure used in the instrumentation drawing may be different. For example, in the plan view 48, the AHU uses a figure in which the characters “AHU” are surrounded by a square, and is drawn as a single element. On the other hand, in the instrumentation drawing, the AHU is divided into four elements (air filter 54, cold / hot water coil 56, humidifier 58, fan 60) constituting the AHU and drawn. The equipment symbol used in the instrumentation drawing is also recorded in the symbol DB 42. The basic instrumentation diagram generation unit 32 refers to the symbol DB 42 and generates a basic instrumentation diagram 52 according to the interpretation result of the connection interpretation unit 30.

The basic instrumentation diagram 52 is created for each predetermined unit. For example, normally, a heat source facility (boiler, refrigerator, cooling tower) is connected to the AHU, but the AHU and the heat source facility are created as separate basic instrumentation diagrams 52. If the basic instrumentation diagram 52 can be created for each of the plurality of instrumentation facilities installed in the building, the processing of the basic instrumentation diagram generation unit 32 is completed.

If the basic instrumentation diagram 52 can be generated, the operator designs the instrumentation based on the plurality of generated basic instrumentation diagrams 52. The second block B2 of the instrumentation design support device 10 supports this instrumentation design. Specifically, the operator selects the basic instrumentation diagram 52 corresponding to the instrumentation equipment for which the instrumentation design is to be performed from the plurality of generated basic instrumentation diagrams 52. The control item presentation unit 34 identifies candidates for control items corresponding to the instrumentation equipment (basic instrumentation diagram 52) selected by the operator and presents them to the operator. The control item is an item for automatic control of instrumentation equipment. For example, control items corresponding to AHU include return air temperature control for keeping the return air temperature at a predetermined value and return for keeping the return air humidity at a predetermined value. There are air-humidity control, warm-up control that prohibits humidification during warm-up control, and the like.

When specifying the control item candidate, the control item presentation unit 34 refers to the control item DB 44. In the control item DB 44, each instrumentation equipment, control items applicable to the instrumentation equipment, and instrumentation parts necessary for realizing the control items are associated and stored. FIG. 5 is an image diagram showing an example of the control item DB 44. As shown in FIG. 5, the control item DB44 includes a control item (second column from the left in FIG. 5) and equipment elements (third column from the left in FIG. 5) that are prerequisites for executing the control item. And are associated and memorized. For example, the return air temperature control can only be performed by equipment having a return air duct (RA) and a cold / hot water coil 56 (CHC) for controlling the temperature of the return air duct. Therefore, the return air temperature control is associated with the return air duct (RA) and the cold / hot water coil 56 (CHC) as its preconditions. Similarly, the return air humidity control can only be performed by equipment having a return air duct (RA) and a humidifier 58 for adjusting the humidity of the return air duct. Therefore, the return air humidity control is associated with the return air duct (RA) and the humidifier 58 as its preconditions. Although each control item is associated with the component of the instrumentation equipment here, the control item and the instrumentation equipment itself may be associated and stored. For example, the return air temperature control and the return air humidity control may be recorded in association with "AHU" as a prerequisite element thereof. In any case, in the control item DB 44, when one instrumentation equipment is selected, the control items are stored in a format that can specify the control items applicable to the instrumentation equipment.

Further, each control item is also associated with component information which is information on one or more instrumentation components necessary for realizing the control item. The component information includes at least the identification information of the instrumentation component (fourth column from the left in FIG. 5) and the mechanical and electrical connection state of the instrumentation component (fifth and sixth columns from the left in FIG. 5). ) And, including. For example, the return air temperature control is a control for keeping the return air temperature at a desired target temperature. When performing this return air temperature control, a thermostat (TED) that measures the return air temperature, an electromagnetic two-way valve (MV1) that controls the flow rate of cold water sent from the cold / hot water coil 56 to the cold water header, and a thermostat are measured. A PLC66 that controls the drive of the electromagnetic two-way valve according to the result is required. Therefore, in the control item DB44, the PLC66, the electromagnetic two-way valve (MV1), and the thermostat (TED) are recorded in association with the item "return air temperature control". Further, the control item DB 44 also records the mechanical and electrical connection relationships of the instrumentation parts. For example, in the case of a thermostat used for controlling the return air temperature, as shown in FIG. 5, it is mechanically installed in the return air duct (RA) and electrically connected to the analog input (Ai) of the PLC66. Information indicating that is recorded in the control item DB 44. As shown in FIG. 5, in the control item DB 44, each control item may be further associated with an explanatory text (first column from the right in FIG. 5) indicating the content thereof and recorded.

The control item presentation unit 34 refers to the control item DB 44 and presents candidates for control items corresponding to the instrumentation equipment selected by the operator. FIG. 6 is a diagram showing an example of a display screen displayed on the display when a candidate for a control item is presented. In the example of FIG. 6, the display screen includes a main window Wm on which the instrumentation diagram is displayed and a sub-window Ws on which the control item candidate list 62 is displayed. In the sub-window Ws, a list of control items that can be selected by the instrumentation equipment displayed in the main window Wm, that is, a candidate list 62 is displayed. The display order of the candidates may be appropriately sorted according to the frequency of adoption and the like. That is, the control item DB 44 may record the number of times each control item has been adopted in the past, and the control item having a larger number of times of adoption may be displayed at a higher level. Further, the candidates for such control items may be narrowed down by the keywords desired by the operator and the types of control parameters (for example, temperature, humidity, etc.). For example, when the operator specifies "temperature" as a control parameter, only control items having "temperature" as a control parameter may be displayed as candidates.

When a control item is selected by the operator, the additional instrumentation diagram generation unit 36 identifies the instrumentation component corresponding to this control item with reference to the control item DB 44, and adds it to the basic instrumentation diagram 52. For example, when "001 return air temperature control" is selected by the operator, the additional instrumentation diagram generation unit 36 refers to the control item DB44 and identifies the instrumentation component corresponding to this control item. In the example of FIG. 5, the thermostat (TED), the electromagnetic two-way valve (MV1), and the PLC are specified as instrumentation parts corresponding to "001 return air temperature control".

If the instrumentation parts can be identified, the additional instrumentation drawing generation unit 36 subsequently adds the instrumentation parts to the basic instrumentation drawing 52. At this time, the additional instrumentation diagram generation unit 36 identifies the connection relationship of each instrumentation component with reference to the control item DB 44, and adds each instrumentation component in a form in which the connection state can be recognized. FIG. 7 is a diagram showing an example of the main window Wm when "001 return air temperature control" is selected as the control item for the AHU instrumentation equipment. In the example of FIG. 7, in the main window Wm, in addition to a plurality of components constituting the instrumentation facility AHU, a PLC, a thermostat (TED), and an electromagnetic two-way valve (MV1) necessary for controlling the return air temperature are provided. It is drawn graphically. Further, according to the control item DB44, the thermostat is mechanically arranged in the return air duct (RA) and electrically connected to the analog input (Ai) of the PLC. Further, the electromagnetic two-way valve is mechanically arranged in the cooling water headline CHR and electrically connected to the analog output (Ao) of the PLC. In addition, the name and description of the currently selected control item is displayed in the upper right corner of this diagram.

In this state, when the operator additionally selects another control item, the instrumentation parts corresponding to the other control item are further added to the additional instrumentation drawing 64. For example, when the operator additionally selects "002 return air humidity control" as a control item, the main window Wm is in the state shown in FIG. In the example of FIG. 8, the instrumentation parts required for the return air humidity control, that is, the fume stat (HD) and the relay (R) are additionally drawn on the additional instrumentation diagram 64. In addition, PLC is also required for return air humidity control, but since PLC is also used for return air temperature control, one PLC is shared by return air temperature control and return air humidity control. The fume stat is mechanically arranged on the return air duct (RA) and electrically connected to the digital input (Di) of the PLC according to the connection state recorded in the control item DB44. Further, the relay is mechanically connected to the humidifier 58 and electrically connected to the digital output (Do) of the PLC.

The operator repeats the process of selecting the control item in this way. Then, if all the desired control items are selected and the instrumentation parts corresponding to these control items can be added to the instrumentation diagram, the additional instrumentation diagram 64 is completed. FIG. 9 is a diagram showing an example of the completed additional instrumentation diagram 64.

The superimposition diagram generation unit 38 generates a superimposition diagram 68 in which the additional instrumentation diagram 64 is superimposed on the read plan view 48. FIG. 10 is a diagram showing an example of superimposed FIG. 68. As shown in FIG. 10, it is desirable that the additional instrumentation diagram 64 is superimposed on the plan view 48 at the position where the instrumentation equipment is arranged. As is clear from FIG. 10, in general, the additional instrumentation diagram 64 is much larger than the symbol of the instrumentation equipment shown in the plan view 48. Therefore, in the superimposed view 68, a part of the information shown in the plan view 48 is hidden behind the additional instrumentation drawing 64 and cannot be seen. In addition, at the design / construction site, it may be desired to refer only to information on a specific control item.

Therefore, in the superimposed view 68, the additional instrumentation diagram 64 may be divided into one or more layers and superimposed on the plan view 48 so that only the layer selected by the operator is displayed. For example, when a plurality of additional instrumentation diagrams 64 are superimposed on one plan view 48, display / non-display may be selected for each additional instrumentation diagram 64 (for each instrumentation facility). .. Further, when a plurality of control items are associated with one additional instrumentation diagram 64, display / non-display may be selected for each control item.

FIG. 11 is a diagram showing an example of a display screen displayed on the display in this case. As shown in FIG. 11, the display screen includes a main window Wm on which the superimposed FIG. 68 is displayed and a sub-window Ws on which the view control screen is displayed. On the view control screen (sub-window Ws), the layer configuration of the superimposed FIG. 68 relating to one building is displayed hierarchically, and the display / non-display of each layer can be selected.

More specifically, in the example of FIG. 11, on the view control screen (sub-window Ws), icons A1 indicating "floor number" are arranged on the first layer, and icons A2 indicating "instrumentation equipment" are arranged on the second layer. Are lined up, and icons A3 indicating "control items" are lined up on the third layer. When one icon A1 indicating the "floor" is selected, the plan view 48 corresponding to the floor is displayed in the main window Wm, and the icon A2 of the "instrumentation equipment" hanging from the floor is expanded and displayed in the sub window Ws. To. By clicking the icon A2 of the expanded and displayed "instrumentation equipment", the display / non-display of the additional instrumentation diagram 64 corresponding to the instrumentation equipment is switched. When the display of the additional instrumentation diagram 64 is instructed, the additional instrumentation diagram 64 corresponding to the instrumentation equipment is displayed superimposed on the plan view 48 in the main window Wm, and is displayed on the instrumentation equipment in the sub window Ws. The hanging "control item" icon A3 is expanded and displayed. By clicking the expanded and displayed "control item" icon A3, the display / non-display of the instrumentation parts corresponding to the control item is switched. In the main window Wm, only the instrumentation parts used in the control items selected for display are displayed in the additional instrumentation diagram 64.

Next, the parts list generation unit 40 generates a list of instrumentation parts based on the generated additional instrumentation drawing 64. At this time, the parts list generation unit 40 specifies a specific product of the instrumentation parts with reference to the parts DB 46. That is, there are a plurality of products having different specifications even if they are the same instrumentation parts. For example, there are a plurality of electromagnetic two-way valves having different specifications such as valve size. Here, the valve size is determined according to the area of the duct / piping to be attached. In other words, the duct / piping size can be said to be a selection condition for selecting a specific product of the electromagnetic two-way valve.

In the component DB 46, the values of the selection conditions for such product selection and the corresponding products are recorded in association with each other. FIG. 12 is a diagram showing an example of the component DB 46. As shown in FIG. 12, the component DB 46 includes a selection table 47 for each type of instrumentation component, and each selection table 47 includes product identification information (for example, model number) and values for selection conditions (for example). (Duct size value) and are recorded in association with each other. The selection table 47 may further include information necessary for preparing a quotation or a purchase order, such as the price and manufacturer of each product.

The parts list generation unit 40 selects a product of instrumentation parts that matches the selection conditions with reference to the parts DB 46. The specific value of the selection condition (for example, the value of the duct size to be used) may be input to the design support device in advance as one of the design conditions, or at the timing of generating the parts list. It may be input by the operator.

The format of the generated parts list 70 can be changed as appropriate according to the instruction from the operator. For example, all the instrumentation parts used in one building may be put together in one parts list 70, or the instrumentation parts used for each floor or each instrumentation equipment may be generated as separate parts list 70. You may. Further, the information included in the parts list 70 may include the number, product name (or product model number), unit price, etc., in addition to the general name of the instrumentation parts to be used. Further, the parts list 70 may be appropriately narrowed down or sorted according to the operator's instruction. FIG. 13 is a diagram showing an example of the parts list 70. In the example of FIG. 13, the parts list 70 displays a list of general names, model numbers, unit prices, and numbers of instrumentation parts.

Next, the flow of instrumentation design using the instrumentation design support device 10 having the above configuration will be described with reference to FIGS. 14 and 15. FIG. 14 is a flowchart showing a flow of generating the basic instrumentation diagram 52 from the plan view 48, that is, a flow of processing in the first block B1 of FIG. FIG. 15 is a flowchart showing a flow of generating the additional instrumentation diagram 64 based on the basic instrumentation diagram 52, that is, a flow of processing in the second block B2 of FIG.

When the basic instrumentation diagram 52 is generated, the plan view 48 in which the instrumentation equipment is drawn in the spatial layout is generated in advance. When there are N plan views 48 related to one building, the operator inputs the N plan views 48 to the instrumentation design support device 10 via the input device 16. For example, when the floor plan 48 is printed out on paper, the operator uses a scanner or a camera to convert the floor plan 48 into electronic data. Further, when the plan view 48 is electronic data (for example, CAD data, image data, etc.) stored in the storage unit of the instrument design support device 10, the operator operates an input device 16 such as a mouse or a keyboard to operate the input device 16. Select the file name of the electronic data.

The drawing reading unit 24 reads the N plan views 48 (S10). The read N plan views 48 are sent to the equipment extraction unit 26 and the line extraction unit 28. Further, the value of the parameter n is initialized to n = 1 (S12). In this state, the equipment extraction unit 26 and the line extraction unit 28 extract the instrumentation equipment and the connection line (duct or pipe) from the nth plan view 48 with reference to the symbol DB 42 (S14, S16). The extraction result is sent to the connection interpretation unit 30. The connection interpretation unit 30 interprets the connection relationship between the instrumentation equipment and the connection line based on the extraction result (S18), and sends the interpretation result to the basic instrumentation diagram generation unit 32. The basic instrumentation diagram generation unit 32 generates the basic instrumentation diagram 52 based on the interpretation result (S20). That is, the instrumentation equipment is converted into a figure suitable for the instrumentation drawing (for example, one instrumentation equipment is converted into a plurality of elements), and a drawing in which a connection duct is connected to each instrumentation drawing is generated. As a general rule, this basic instrumentation diagram 52 is generated for each instrumentation facility. Therefore, when k instrumentation facilities are included in one plan view 48, one plan view 48 to k A number of basic instrumentation diagrams 52 are generated.

If the basic instrumentation drawing 52 can be generated based on the nth plan view 48, it is subsequently determined whether or not the parameter n has reached the number N of the plan view 48 (S22). As a result of the determination, when n = N, the generation of the basic instrumentation diagram 52 is completed. On the other hand, when n <N, the parameter n is incremented (S24), and then steps S14 to S20 are repeated.

The procedure for generating the basic instrumentation diagram 52 described here is an example, and may be changed as appropriate as necessary. For example, after the generation of the basic instrumentation diagram 52, the operator may perform a pass / fail judgment process or a correction process on the generated basic instrumentation diagram 52. Further, it is not necessary to generate the basic instrumentation drawing 52 for all N plan views 48, and the basic instrumentation drawing 52 may be generated only for the plan view 48 desired by the operator.

Next, the flow of generating the additional instrumentation diagram 64 from the basic instrumentation diagram 52 will be described with reference to FIG. If the basic instrumentation diagram 52 can be generated, the operator selects the instrumentation equipment to be instrumented and designed (S26). When the instrumentation equipment is selected by the operator, the control item presentation unit 34 refers to the control item DB 44 and presents the operator a candidate for the control item applicable to the selected instrumentation equipment (S28). Then, the process waits until the operator selects the control item (Yes in S30) or the end instruction (Yes in S36). When the control item is selected by the operator, the additional instrumentation diagram generation unit 36 refers to the control item DB44 and identifies the instrumentation parts required for the selected control item (S32). Then, the specified instrumentation component is added to the basic instrumentation diagram 52 to generate the additional instrumentation diagram 64 (S34). Then, steps S28 to S34 are repeated until the operator gives an end instruction.

If there is an end instruction (Yes in S36) from the operator, the generation of the additional instrumentation diagram 64 relating to the current instrumentation equipment is completed. Then, if the next instrumentation equipment is selected, steps S28 to S34 are repeated again. On the other hand, if the additional instrumentation diagram 64 can be generated for all the instrumentation equipment (Yes in S40), all the processes are completed.

The generated additional instrumentation diagram 64 is stored in the storage unit together with the information indicating which instrumentation equipment in the plan view 48 corresponds to. Then, the stored additional instrumentation diagram 64 is used for generating the superimposed diagram 68 and the component list 70.

As is clear from the above description, according to the technique disclosed herein, candidates for applicable control items are presented for each instrumentation facility. Therefore, even if the operator has little experience or knowledge, the control items suitable for the instrumentation equipment can be appropriately selected. Further, according to the technique disclosed in the present specification, the instrumentation parts corresponding to the control items selected by the operator are automatically identified and added to the instrumentation drawing. Therefore, the operator does not need to specify a part or consider the connection relationship of the part, and the burden on the operator can be significantly reduced. Moreover, even if the operator has little experience or knowledge, appropriate instrumentation parts can be arranged in an appropriate connection relationship. That is, according to the technique disclosed in the present specification, the instrumentation design can be performed more easily.

Further, according to the technique disclosed in the present specification, the basic instrumentation drawing 52 is automatically generated from the plan view 48. As a result, the labor required to generate the basic instrumentation diagram 52 can be significantly reduced. Further, according to the technique of the present specification, a superposed view 68 in which the plan view 48 and the additional instrumentation drawing 64 are combined is generated. Therefore, since the spatial layout and the contents of the instrumentation design can be grasped at the same time, the installation work and maintenance of the instrumentation parts can be performed more easily. Further, according to the technique of the present specification, a list of instrumentation parts can be automatically generated. Therefore, the labor of quotation, purchase order, parts management, etc. can be further reduced.

The configuration described so far is an example, and the instrumentation design support device 10 includes at least a control item DB 44, a control item presentation unit 34 that presents control item candidates with reference to the control item DB 44, and an operator. Other configurations may be appropriately modified as long as it includes an additional instrumentation diagram generation unit 36 that identifies and adds instrumentation parts corresponding to the control items selected by. Therefore, the basic instrumentation diagram 52 and the instrumentation design support device 10 may be generated by completely different devices. Further, the instrumentation design support device 10 does not have to have a function of generating the parts list 70 and the superimposed view 68. Further, in the above description, only the device that supports the instrumentation design of the building air conditioner has been described as an example, but the instrumentation design support device may support the instrumentation design of other equipment.
