Description

Instrumentation design support device

The present specification supports instrumentation design for determining a configuration necessary for automatic control of the instrumentation equipment based on a basic instrumentation diagram including an instrumentation part and a connection line connected to the instrumentation part. An instrumentation design support device is disclosed.

Facilities such as buildings and plants are equipped with various facilities. For example, facilities related to air conditioning, water supply / drainage, electricity, and lighting are provided in buildings. In addition, production facilities and management facilities are provided in the plant. When designing a facility such as a building or a plant, it is necessary to determine the arrangement of these various facilities.

Furthermore, when such facility design is performed, instrumentation design is performed in which the state of various facilities provided in the facility is measured and a configuration for automatically controlling the facility is determined according to the measurement result. In the instrumentation design, control items to be executed are usually determined for each equipment (instrumentation equipment) that is subject to automatic control, and further, parts (instrumentation parts) necessary to implement the control items are selected. In the instrumentation design, a diagram showing the connection relationship between the selected instrumentation component and the instrumentation facility, that is, a so-called instrumentation diagram is generated. Based on the generated instrumentation diagram, installation and maintenance of instrumentation parts are performed.

However, in the past, in order to perform such instrumentation design, the designer had to have abundant experience and knowledge. Further, even a designer who has sufficient experience and knowledge has been troublesome to perform instrumentation design for a plurality of facilities.

In order to automatically generate the management point data, in Patent Document 1, a case database storing instrumentation diagram data and management point data regarding a plurality of past cases is provided, and a similar past selected by searching the case database. Instrumentation diagram data and management point data of the case are acquired, and management point data of the current case is generated based on the data of the similar past case.

Patent Document 2 discloses a technique for creating a list of device data from P & ID data. P & ID data is data indicating 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 this P & ID data, and a list of plant data included in the P & ID data is created based on the extracted information. .

Such technology can reduce the burden of facility design to some extent. However, both

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

This 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 equipments installed in the facility. Such instrumentation design includes, for example, instrumentation design for air conditioning equipment in buildings, instrumentation design for water supply / drainage equipment in buildings, and instrumentation design for various production facilities and management facilities in industrial plants. 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 technology disclosed in this specification is not limited to building air conditioning equipment, and may be applied to instrumentation design support related to other equipment.

The instrumentation design support apparatus 10 is physically constructed by one or more computers that are driven according to a specific program. That is, as shown in FIG. 1, the instrumentation design support apparatus 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 / F 20”). These are connected by a bus 22.

CPU 12 performs various calculations. Specifically, the CPU 12 reads a design support program stored in the storage device 14 according to instructions from the operator, and performs various calculations necessary for design support. 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 diagram generation process, a parts list 70 generation process, and the like, which will be described later. 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 an operation instruction and data input from an operator, and is configured by combining, for example, one or more of a keyboard, a mouse, a touch panel, a microphone, a scanner that reads drawings printed on paper, a camera, 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. Although not shown in FIG. 1, the instrumentation design support apparatus 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 and the superimposed diagram generated by the instrumentation design support apparatus 10 may be sent to another information terminal via the communication I / F 20.

In FIG. 1, the instrumentation design support apparatus 10 is illustrated as a single computer, but the instrumentation design support apparatus 10 may be configured by a plurality of computers that can communicate with each other. Therefore, for example, the instrumentation design support apparatus 10 may be composed of a main computer and a tablet terminal that can communicate with the main computer and is used by an operator at the work site. The various DBs can communicate with the main computer and may be stored in another computer that functions as a data server.

FIG. 2 is a functional block diagram of the instrumentation design support apparatus 10. The instrumentation design support apparatus 10 adds the first block B1 for generating the basic instrumentation diagram 52 from the plan view 48 and the instrumentation parts necessary for automatic control of the 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 blocks referenced in the first to third blocks B3. And 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 function of the fourth block B4 is realized exclusively by the storage device 14.

Here, a plan view is a duct layout and piping connecting instrumentation equipment and instrumentation equipment in the plan layout diagram of the facility (in this example, building) (hereinafter referred to as “connection line” if the duct and piping are not distinguished). It is a facility diagram that draws Equipment diagrams (plan views) include electrical equipment diagrams depicting electrical facilities, water supply / drainage facility diagrams depicting water supply / drainage facilities, air conditioning facility diagrams depicting air conditioning facilities, etc. In order to design, the air-conditioning equipment diagram is handled as a plan view.

Also, instrumentation equipment is equipment whose positional relationship with the space layout is important, and is a target of instrumentation design. In this example, in order to perform instrumentation design for air conditioning equipment, air handling units (hereinafter referred to as “AHU”), air conditioning equipment such as packaging air conditioners, cooling towers, and boilers are instrumentation equipment. Such instrumentation equipment is drawn on a plan view because the positional relationship with the space layout is important.

The basic instrumentation diagram is a diagram showing the connection relationship between instrumentation equipment and connection lines. In this example, this basic instrumentation diagram is automatically generated from a plan view. In the basic instrumentation diagram, the instrumentation equipment is drawn by being divided into a plurality of components as necessary. For example, the AHU is drawn as a single element in the plan view, but in the basic instrumentation diagram, the AHU is divided into a plurality of elements such as an air filter, a cold / hot water coil, a humidifier, and a fan constituting the AHU. And rendered. This is to make it easy to understand the connection relationship between an instrumentation part (described later) and each element.

The additional instrumentation diagram is a drawing in which one or more instrumentation parts necessary for automatic control of instrumentation equipment are added to the basic instrumentation diagram, and shows the connection relationship between the instrumentation equipment and one or more instrumentation parts. It is a drawing. Here, as described above, the instrument part is a device necessary for automatically controlling the instrumentation equipment, and the positional relationship with the space layout is not important, and the connection relation with the instrumentation equipment is exclusively used. It is an important device. Instrumentation parts include, for example, a programmable controller (hereinafter referred to as “PLC”) that processes signals necessary for control, sensors that detect various physical quantities, actuators that drive each part, valves that open and close flow paths, Relays that connect / cut off signals are included. In the additional instrumentation diagram, the connection relationship between these instrumentation components and instrumentation equipment is drawn in a diagrammatic manner.

Next, the functional block diagram shown in FIG. 2 will be described with specific examples. The drawing reading unit 24 reads a plan view 48 of the target facility, and converts the plan view 48 into a data format that can be referred to by the subsequent facility extraction unit 26 and the like. 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. 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, the data format. Perform the conversion. Then, the drawing reading unit 24 outputs the plan view data in a desired data format to the line extraction unit 28, the facility extraction unit 26, and the superimposed diagram generation unit 38. Here, it is assumed that only the plan view 48 is input to the instrumentation design support apparatus 10, but various design conditions (for example, an air conditioning method and a duct size) may be input together with the plan view 48.

FIG. 3 is an image diagram of the plan view 48. As shown in FIG. 3, the plan view 48 includes a figure showing a plane layout, a figure showing instrumentation (including letters), and a figure (including letters) showing ducts and pipes connected to the instrumentation equipment. ) And are included. Note that the plan view 48 shown in FIG. 3 is greatly simplified compared to the normal plan view 48 for ease of explanation. 3 is also different from the graphic used in the actual plan view 48. In FIG.

The facility extraction unit 26 extracts instrumentation facilities from the plan view 48. In this extraction, the facility extraction unit 26 refers to the symbol DB 42. In the plan view 48, the symbol DB 42 stores a graphic indicating instrumentation equipment (hereinafter referred to as “equipment symbol”) and a graphic indicating connection lines (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 enclosed in a rectangle. Further, in the plan view 48, the return air duct is represented as a line with the letters “RA”. In the symbol DB 42, a graphic (equipment symbol) indicating an instrumentation facility and a graphic (line symbol) indicating a connection line in the plan view 48 are stored in association with identification information of the corresponding instrumentation facility and connection line. Yes.

The facility extraction unit 26 extracts a figure that matches the facility symbol from the input plan view 48 using a technique such as image matching. This extraction may be performed for all the facility symbols stored in the symbol DB 42, or may be performed only for the group of facility symbols designated in advance 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 can 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. By setting it as this structure, the calculation amount of the instrumentation design support apparatus 10 can be reduced. If a figure that matches 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. The data is output to the connection interpretation unit 30.

The line extraction unit 28 extracts connection lines (ducts and pipes) from the plan view 48 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 facility extraction unit 26 further extracts a line connected to the line symbol. If all the line symbols and the lines connected to the line symbols can be extracted, the facility extraction unit 26 uses the connection interpretation unit to identify the connection line identification information corresponding to the line symbol and the drawing position of the line connected to the line symbol in the plan view 48. Output to 30.

Note that this connection line extraction may also be performed for all line symbols stored in the symbol DB 42, or may be performed only for a group of line symbols designated in advance by the operator. Moreover, 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 connection lines extracted from the plan view 48 are displayed in a special form (for example, highlight display, different color display, marker addition, etc.). May be. If there is an error in the extraction result, the operator may be able to correct it manually.

The connection interpretation unit 30 interprets the connection relationship between the instrumentation equipment drawn in the plan view 48 and the connection line based on the information input from the equipment extraction unit 26 and the line extraction unit 28. For example, when the end of a line indicating one return air duct reaches an equipment symbol indicating AHU, the connection interpretation unit 30 interprets that the return air duct is connected to the AHU. Such interpretation results are 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 in the connection interpretation unit 30. As described above, the basic instrumentation diagram is a diagram in which instrumentation equipment and connection lines connected to the instrumentation facility are represented in a diagrammatic manner. FIG. 4 is a diagram showing an example of the basic instrumentation diagram 52. Here, as is apparent from FIG. 4, in the basic instrumentation diagram 52, the instrumentation equipment is represented by a graphic suitable for the instrumentation diagram. That is, even in the same instrumentation facility, the figure used in the plan view 48 may be different from the figure used in the instrumentation drawing. For example, in the plan view 48, the AHU uses a figure in which the characters “AHU” are enclosed by a square, and is drawn as a single element. On the other hand, in the instrumentation diagram, the AHU is drawn by being divided into four elements (the air filter 54, the cold / hot water coil 56, the humidifier 58, and the fan 60) constituting the AHU. In the symbol DB 42, equipment symbols used in the instrumentation diagram are also recorded. 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 in the connection interpretation unit 30.

Note that the basic instrumentation diagram 52 is created for each predetermined unit. For example, a heat source facility (boiler, refrigerator, cooling tower) is normally 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 a 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 performs instrumentation design based on the plurality of generated basic instrumentation diagrams 52. The second block B2 of the instrumentation design support apparatus 10 supports this instrumentation design. Specifically, the operator selects a basic instrumentation diagram 52 corresponding to an instrumentation facility to be instrumented from among the plurality of generated basic instrumentation diagrams 52. The control item presentation unit 34 specifies control item candidates corresponding to the instrumentation equipment (basic instrumentation diagram 52) selected by the operator, and presents it to the operator. Control items are items for automatic control of instrumentation equipment. For example, control items corresponding to AHU include return air temperature control for maintaining the return air temperature at a predetermined value and return air temperature for maintaining the return air humidity at a predetermined value. There are air humidity control, warming up control for prohibiting humidification during warming up control, and the like.

When specifying control item candidates, the control item presentation unit 34 refers to the control item DB 44. In the control item DB 44, each instrumentation facility, a control item applicable to the instrumentation facility, and an instrument part necessary for realizing the control item are stored in association with each other. FIG. 5 is an image diagram illustrating an example of the control item DB 44. As shown in FIG. 5, the control item DB 44 includes a control item (second column from the left in FIG. 5) and a facility element (third column from the left in FIG. 5) that is a prerequisite for executing the control item. Are stored in association with each other. For example, the return air temperature control can be performed only with equipment having a return air duct (RA) and a cold / hot water coil 56 (CHC) for adjusting 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 the prerequisite elements. Similarly, the return air humidity control can be executed only by a facility having a return air duct (RA) and a humidifier 58 for adjusting the humidity of the return air duct. Accordingly, the return air humidity control is associated with the return air duct (RA) and the humidifier 58 as prerequisite elements. In addition, although each control item and the component of instrumentation equipment are matched here, you may memorize | store and associate a control item and instrumentation equipment itself. For example, “AHU” may be recorded in association with the return air temperature control and the return air humidity control as the prerequisite elements. In any case, in the control item DB 44, when one instrumentation facility is selected, the control items are stored in a format that can identify control items applicable to the instrumentation facility.

Each control item is also associated with component information which is information of one or more instrumentation components necessary for realizing the control item. The component information includes at least instrumentation component identification information (fourth column from the left in FIG. 5) and mechanical and electrical connection states of the instrumentation component (the fifth and sixth columns from the left in FIG. 5). ) And. For example, the return air temperature control is control for maintaining the return air temperature at a desired target temperature. When this return air temperature control is performed, a thermostat (TED) for measuring the return air temperature, an electromagnetic two-way valve (MV1) for controlling the flow rate of cold water sent from the cold / hot water coil 56 to the cold water header, and measurement of the thermostat. The PLC 66 that controls the driving of the electromagnetic two-way valve according to the result is required. Therefore, the control item DB 44 records the PLC 66, the electromagnetic two-way valve (MV1), and the thermostat (TED) in association with the item “return air temperature control”. The control item DB 44 also records the mechanical and electrical connection relationships of the instrument parts. For example, in the case of a thermostat used for return air temperature control, 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 PLC 66. Is recorded in the control item DB 44. As shown in FIG. 5, in the control item DB 44, an explanatory text (first column from the right in FIG. 5) indicating the contents may be further recorded in association with each control item.

The control item presentation unit 34 refers to the control item DB 44 and presents control item candidates corresponding to the instrumentation equipment selected by the operator. FIG. 6 is a diagram illustrating an example of a display screen displayed on the display when the control item candidates are presented. In the example of FIG. 6, the display screen includes a main window Wm in which an instrumentation diagram is displayed, and a sub-window Ws in which a 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. Note that the display order of the candidates may be appropriately sorted according to the adoption frequency or the like. That is, the past number of times of adoption of each control item may be recorded in the control item DB 44, and a control item having a larger number of times of adoption may be displayed at the top. Further, such control item candidates may be narrowed down by a keyword desired by the operator and the type of control parameter (for example, temperature, humidity, etc.). For example, when the operator designates “temperature” as the control parameter, only the control items having “temperature” as the control parameter may be displayed as candidates.

If the control item is selected by the operator, the additional instrumentation diagram generation unit 36 specifies an instrumentation part corresponding to the 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 DB 44 and specifies an instrumentation part 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 instrument parts corresponding to “001 return air temperature control”.

If the instrumentation part can be specified, the additional instrumentation diagram generation unit 36 then adds the instrumentation part to the basic instrumentation diagram 52. At this time, the additional instrumentation diagram generation unit 36 refers to the control item DB 44, identifies the connection relationship of each instrumentation component, and adds each instrumentation component in a form in which this connection state can be recognized. FIG. 7 is a diagram illustrating an example of the main window Wm when “001 return air temperature control” is selected as the control item for the instrumentation equipment of the AHU. In the example of FIG. 7, the main window Wm includes a PLC, a thermostat (TED), and an electromagnetic two-way valve (MV1) necessary for return air temperature control, in addition to a plurality of components constituting the instrumentation equipment AHU. It is drawn as a diagram. In accordance with the control item DB 44, the thermostat is mechanically arranged in the return air duct (RA) and electrically connected to the analog input (Ai) of the PLC. The electromagnetic two-way valve is mechanically disposed on the coolant headline CHR and electrically connected to the analog output (Ao) of the PLC. Furthermore, the name and description of the currently selected control item are displayed in the upper right of the diagram.

In this state, when the operator further selects another control item, an instrument part corresponding to the other control item is further added to the additional instrumentation diagram 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, instrumentation parts necessary for return air humidity control, that is, a fume stat (HD) and a relay (R) are additionally drawn in the additional instrumentation diagram 64. Note that the return air humidity control also requires a PLC, but since the PLC is also used in the return air temperature control, one PLC is shared by the return air temperature control and the return air humidity control. The fume stat is mechanically arranged on the return air duct (RA) according to the connection state recorded in the control item DB 44, and electrically connected to the digital input (Di) of the PLC. 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 control items in this way. Then, if all desired control items are selected and 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 superimposed diagram generation unit 38 generates a superimposed diagram 68 in which the additional instrumentation diagram 64 is superimposed on the read plan view 48. FIG. 10 is a diagram illustrating an example of the superimposed diagram 68. As shown in FIG. 10, it is desirable that the additional instrumentation diagram 64 is superimposed on the position of the instrumentation facility in the plan view 48. Note that, as is apparent from FIG. 10, the additional instrumentation diagram 64 is generally much larger than the symbol of the instrumentation facility described in the plan view 48. Therefore, in the superimposed diagram 68, some information described in the plan view 48 is hidden behind the additional instrumentation diagram 64 and cannot be seen. In addition, at the design / construction site, it may be desired to refer only to information related to specific control items.

Therefore, in the superimposition diagram 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 a single plan view 48, display / non-display may be selected for each additional instrumentation diagram 64 (each instrumentation facility). . 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 diagram 68 is displayed, and a sub window Ws on which the view control screen is displayed. On the view control screen (subwindow Ws), the layer configuration of the superimposed diagram 68 relating to one building is hierarchically displayed, and display / non-display of each layer can be selected.

More specifically, in the example of FIG. 11, on the view control screen (subwindow Ws), an icon A1 indicating “floor” is arranged in the first layer, and an icon A2 indicating “instrumentation equipment” is displayed in the second layer. Are arranged, and an icon A3 indicating "control item" is arranged in the third layer. When one icon A1 indicating “floor” is selected, a plan view 48 corresponding to the floor is displayed in the main window Wm, and an “instrumentation” icon A2 hanging from the floor is expanded and displayed in the sub-window Ws. The By clicking on the “instrumentation equipment” icon A <b> 2 displayed in an expanded manner, 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 facility is displayed superimposed on the plan view 48 in the main window Wm, and the instrumentation facility is displayed in the sub window Ws. A hanging “control item” icon A3 is expanded and displayed. By clicking the icon “A3” of the “control item” displayed in an expanded manner, display / non-display of the instrumentation part corresponding to the control item is switched. In the main window Wm, only instrument parts used in the control item selected for display are displayed in the additional instrumentation diagram 64.

Next, the parts list generation unit 40 generates a list of instrument parts based on the generated additional instrumentation diagram 64. At this time, the component list generation unit 40 refers to the component DB 46 and identifies a specific product of the instrument component. That is, there are a plurality of products with different specifications even for the same instrumentation part. For example, the electromagnetic two-way valve includes a plurality of products having different specifications such as a valve size. Here, the valve size is determined according to the area of the duct / pipe to be attached. In other words, the duct / pipe size is a selection condition for selecting a specific product of the electromagnetic two-way valve.

In the parts DB 46, values of such selection conditions for product selection and corresponding products are recorded in association with each other. FIG. 12 is a diagram illustrating an example of the component DB 46. As shown in FIG. 12, the parts DB 46 includes a selection table 47 for each type of instrumentation part, and each selection table 47 includes product identification information (for example, a model number) and values of selection conditions (for example, Are recorded in association with each other. It should be noted that the selection table 47 may further include information necessary for creating an estimate or purchase order, such as the price or manufacturer of each product.

The parts list generation unit 40 refers to the parts DB 46 and selects an instrument part product that meets the selection conditions. A specific value of the selection condition (for example, the value of the duct size to be used) may be input to the design support apparatus in advance as one of the design conditions, or at the timing of parts list generation. An operator may input it.

The format of the generated parts list 70 can be appropriately changed according to an instruction from the operator. For example, all instrument parts used in one building may be combined into one part list 70, or the instrument parts used for each floor or for each instrumentation facility are generated as separate parts lists 70. May be. Further, the information included in the parts list 70 may include the general name of the instrumentation part to be used, the number, the product name (or product model number), the unit price, and the like. Further, the parts list 70 may be appropriately narrowed down or sorted according to an instruction from the operator. FIG. 13 is a diagram illustrating 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 apparatus 10 having the above configuration will be described with reference to FIGS. FIG. 14 is a flowchart showing the flow of generating the basic instrumentation diagram 52 from the plan view 48, that is, the processing flow 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 process flow in the second block B2 of FIG.

When generating the basic instrumentation diagram 52, a plan view 48 in which instrumentation equipment is drawn in the space 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 plan view 48 is printed out on paper, the operator converts the plan view 48 into electronic data using a scanner or a camera. When the plan view 48 is electronic data (for example, CAD data or image data) stored in the storage unit of the instrumentation design support device 10, the operator operates the input device 16 such as a mouse or a keyboard, 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. Also, the value of parameter n is initialized to n = 1 (S12). In this state, the equipment extraction unit 26 and the line extraction unit 28 extract instrumentation equipment and connection lines (ducts or pipes) from the nth plan view 48 while referring 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 a basic instrumentation diagram 52 based on the interpretation result (S20). That is, the instrumentation facility is converted into a figure suitable for the instrumentation diagram (for example, one instrumentation facility is converted into a plurality of elements), and a drawing in which a connection duct is connected to each instrumentation diagram is generated. Since this basic instrumentation diagram 52 is generated for each instrumentation facility as a rule, if k instrumentation facilities are included in one plan view 48, one plan view 48 to k. Basic instrumentation diagrams 52 are generated.

If the basic instrumentation diagram 52 can be generated based on the nth plan view 48, it is then determined whether the parameter n has reached the number N of plan views 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, if n <N, the parameter n is incremented (S24) and then steps S14 to S20 are repeated.

Note that the generation procedure of the basic instrumentation diagram 52 described here is an example, and may be appropriately changed as necessary. For example, after the generation of the basic instrumentation diagram 52, there may be a pass / fail judgment process or a correction process by the operator for the generated basic instrumentation diagram 52. The basic instrumentation diagram 52 need not be generated for all the N plan views 48, and the basic instrumentation diagram 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 an instrumentation facility to be instrumented (S26). If the instrumentation facility is selected by the operator, the control item presenting unit 34 refers to the control item DB 44 and presents the control item candidate applicable to the selected instrumentation facility to the operator (S28). The process waits until a control item is selected by the operator (Yes in S30) or an end instruction is given (Yes in S36). When the control item is selected by the operator, the additional instrumentation diagram generation unit 36 refers to the control item DB 44 and specifies an instrumentation component necessary for the selected control item (S32). And the specified instrumentation part is added to the basic instrumentation figure 52, and the additional instrumentation figure 64 is produced | generated (S34). The steps S28 to S34 are repeated until an end instruction is issued from the operator.

If there is a termination instruction from the operator (Yes in S36), the generation of the additional instrumentation diagram 64 relating to the current instrumentation equipment is terminated. 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 instrumentation facilities (Yes in S40), all the processes are ended.

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

As is clear from the above description, according to the technology disclosed in this specification, applicable control item candidates are presented for each instrumentation facility. Therefore, even if the operator's experience and knowledge are scarce, it is possible to appropriately select control items suitable for instrumentation equipment. Further, according to the technique disclosed in this specification, an instrument part corresponding to a control item selected by an operator is automatically identified and added to the instrument drawing. Therefore, it is not necessary for the operator to specify a part or to consider the connection relation of the part, and the burden on the operator can be greatly reduced. In addition, even if the operator's experience and knowledge are scarce, it is possible to arrange appropriate instrumentation components in an appropriate connection relationship. That is, according to the technique disclosed in this specification, the instrumentation design can be performed more easily.

Further, according to the technique disclosed in this specification, the basic instrumentation diagram 52 is automatically generated from the plan view 48. As a result, the labor required for generating the basic instrumentation diagram 52 can be greatly reduced. Furthermore, according to the technique of this specification, the superimposition figure 68 which combined the top view 48 and the additional instrumentation figure 64 is produced | generated. For this reason, since the space 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 this specification, a list of instrument parts can be automatically generated. For this reason, it is possible to further reduce the troubles such as quotations, purchase orders, and parts management.

The configuration described so far is an example, and the instrumentation design support apparatus 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. As long as the additional instrumentation diagram generation unit 36 that specifies and adds an instrumentation part corresponding to the control item selected by is included, other configurations may be appropriately changed. Therefore, the basic instrumentation diagram 52 and the instrumentation design support apparatus 10 may be generated by completely different apparatuses. Further, the instrumentation design support apparatus 10 may not have a function of generating the parts list 70 and the superimposed diagram 68. In the description so far, only the device that supports the instrumentation design of the building air conditioning equipment has been described as an example. However, the instrumentation design support device may support the instrumentation design of other facilities.
