[0004] The present disclosure aims to significantly improve the efficiency of the pick-up work and significantly reduce the time required for the pick-up work.

[0005] A support information providing method according to one aspect of the present disclosure is a support information providing method in a construction site support system that is connected to a terminal device via a network and stores construction floor plans for each specified floor of the same building, including building material symbols, and includes the steps of: identifying the total number of specific building material symbols included in the construction floor plans corresponding to all floors included in the specified floors; identifying the number of the specific building material symbols included on the construction floor plan corresponding to each one of the specified floors; inputting an instruction from the terminal device to select one of the specified floors; and, if the one floor indicates a first floor from the terminal device, displaying the total number and a first number of the specific building material symbols included on the construction floor plan corresponding to the first floor on the terminal device; and, in response to an instruction to move from the display of the first floor to the display of a second floor among the specified floors, switching to displaying the total number and the second number of the specific building material symbols included on the construction floor plan corresponding to the second floor.

[0009] (Knowledge that formed the basis of the invention) Conventionally, workers would visually check and pick out the building material symbols representing the target equipment, such as automatic fire alarms and wiring devices, from the construction floor plan, tally up the building material symbols for each piece of target equipment, and then create an estimate.

[0010] Construction floor plans contain a huge number of building material symbols, and depending on the type of construction equipment, the number of building material symbols can exceed 100. In addition, the size of each building material symbol is small, so the work of workers manually selecting each building material symbol one by one is extremely inefficient and takes a considerable amount of time. As a result, the man-hours required to create estimates are increasing.

[0011] Under these circumstances, there is a need to reduce the time required for the pick-up work.

[0012] Patent Document 1 also discloses a business that calculates electrical work costs by extracting (picking out) the names and quantities of electrical appliances from architectural design drawings provided by a customer and accumulating these. Patent Document 1 also suffers from the problem that the work of calculating electrical work costs, such as the extraction of electrical appliance symbols and text, must be done essentially manually, resulting in extremely inefficient work. Patent Document 1 discloses a technology for extracting symbols similar to multiple symbols defined in a legend from the actual design drawings in image data by shifting a rectangular dot pattern of multiple symbols by one dot in a specified rectangular area and comparing it with the design drawing to calculate a correlation coefficient. Symbols whose correlation coefficient function calculated for each symbol exceeds a predetermined threshold and whose neighboring symbols do not exceed the predetermined threshold are extracted as correct. However, Patent Document 1 only extracts electrical appliance symbols and text, and further improvement is needed.

[0013] Here, by informing the total number of specific building material symbols included in the construction floor plan corresponding to all floors included in the specified floor, and the number of specific building material symbols included in the construction floor plan corresponding to one floor included in the specified floor, it is ultimately sufficient to know the total number, but at the confirmation stage it is convenient to know the number of specific building material symbols for each floor.

[0014] According to this aspect, when a first floor among the specified floors is displayed and the total number and the first number of specific building material symbols included on the construction floor plan corresponding to the first floor are displayed, if an instruction is given to move from the display of the first floor to the display of the second floor among the specified floors, the display automatically switches to the display of the total number and the second number of specific building material symbols included on the construction floor plan corresponding to the second floor.

[0015] At this time, no special instruction is given to switch between the first number and the second number. That is, the operation of moving from the display of the first floor to the display of the second floor also serves as an instruction to switch between the first number and the second number.

[0016] This makes it possible, through simple operations, to check which floor the mistake occurred in picking out the building material symbols on, even if there is an error in the total number, since there is a high probability that the number of specific building material symbols on each floor is the same if the construction floor plan is the same, thereby making it possible to efficiently check the picking out of building material symbols.

[0017] Furthermore, if a specific building material symbol is zero on a certain floor, it can be easily determined that there is a high possibility that something that should have been identified has not been identified.

[0018] As a result, the efficiency of the picking up work can be improved significantly, and the time required for the picking up work can be significantly reduced.

[0019] A support information providing method of technology 1 according to one aspect of the present disclosure is a support information providing method in a construction site support system that is connected to a terminal device via a network and stores construction floor plans for each predetermined floor of the same building, the support information providing method including: identifying a total number of specific building material symbols included in the construction floor plans corresponding to all floors included in the predetermined floors; identifying the number of the specific building material symbols included on the construction floor plan corresponding to each one of the predetermined floors; inputting an instruction from the terminal device to select one of the predetermined floors; when the one floor indicates a first floor from the terminal device, displaying the total number and a first number of the specific building material symbols included on the construction floor plan corresponding to the first floor; and switching to displaying the total number and a second number of the specific building material symbols included on the construction floor plan corresponding to the second floor in response to an instruction to move from the display of the first floor to the display of a second floor among the predetermined floors.

[0020] This method of providing support information can simultaneously present the user with the number of specific building material symbols included in the construction floor plan, both for each floor and for the entire building, thereby enabling the user to easily check for errors in the work of identifying building material symbols, thereby significantly improving the efficiency of the work and significantly reducing the time required for the work.

[0021] Furthermore, Technology 2 is the support information providing method of Technology 1, in which the specific building material symbol indicates an automatic fire alarm.

[0022] According to this method of providing support information, when a user is extracting building material symbols indicating automatic fire alarms from a construction floor plan, the extraction process can be made much more efficient and the time required for the extraction process can be significantly reduced.

[0023] Furthermore, Technology 3 is the support information providing method of Technology 1 or 2, in which the specific building material symbol indicates a wiring device.

[0024] According to this method of providing support information, when a user is working to extract building material symbols indicating wiring devices from a construction floor plan, the extraction process can be made significantly more efficient and the time required for the extraction process can be significantly reduced.

[0025] Furthermore, Technology 4 is a support information providing method according to any one of Technology 1 to Technology 3, wherein the construction site support system includes a database that stores position information of the specific building material symbols included in the construction floor plan of each floor included in the same building in correspondence with position coordinate information on the construction floor plan of each floor.

[0026] This method of providing support information can present the user with the number of specific building material symbols contained in a construction floor plan by storing the location information of the building material symbols in a database in association with the position coordinate information on the floor plan.

[0027] A construction site support system of Technology 5 according to one aspect of the present disclosure is a construction site support system that is connected to a terminal device via a network and stores construction floor plans for each predetermined floor of the same building, including building material symbols, and that identifies the total number of specific building material symbols included in the construction floor plans corresponding to all floors included in the predetermined floors, identifies the number of the specific building material symbols included on the construction floor plan corresponding to each one of the predetermined floors, and inputs an instruction to select one of the predetermined floors from the terminal device, and when the one floor indicates a first floor from the terminal device, causes the terminal device to display the total number and a first number of the specific building material symbols included on the construction floor plan corresponding to the first floor, and switches to displaying the total number and a second number of the specific building material symbols included on the construction floor plan corresponding to the second floor in response to an instruction to move from the display of the first floor to the display of a second floor among the predetermined floors.

[0028] Such a construction site support system can simultaneously display the number of specific building material symbols included in the construction floor plan to the user, both for each floor and for the entire building, thereby significantly reducing the time required for the user to pick up the symbols.

[0029] A terminal device of Technology 6 according to one aspect of the present disclosure is a terminal device in a construction site support system of Technology 5, which, when a first floor among the predetermined floors is specified, acquires the total number and a first number of the specific building material symbols included on a construction floor plan corresponding to the first floor from the construction site support system, displays the total number and the first number of the specific building material symbols on a display, and, in response to an instruction to move from the display of the first floor to the display of a second floor among the predetermined floors, acquires the total number and a second number of the specific building material symbols included on a construction floor plan corresponding to the second floor from the construction site support system, and switches to displaying the total number and the second number of the specific building material symbols.

[0030] With such a terminal device, users can simultaneously check the number of specific building material symbols contained in a construction floor plan, both for each floor and for the entire building, thereby significantly reducing the time required for the extraction process.

[0031] (Embodiments) A support information providing method, construction site support system, and terminal device according to the present embodiments will be described in detail below with reference to Figures 1 to 10. Note that the numerical values, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components that are not recited in independent claims will be described as optional components that make up preferred embodiments.

[0032] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0033] [Configuration] First, a description will be given of the configuration of a construction site support system 10 according to an embodiment. Fig. 1 is a block diagram showing the functional configuration of a construction site support system 10 according to an embodiment.

[0034] The construction site support system 10 is a system that can extract the number and positions of building material symbols for each building material symbol based on the design drawings of a building and information indicating the type of building material symbol included in the design drawings. Furthermore, the construction site support system 10 is a system that can simultaneously present to the user the number of extracted building material symbols included in one drawing and the number included in a drawing of the entire building. Here, the design drawings of a building are floor plans for construction, and are created, for example, using a CAD (Computer Aided Design) system. Extracting design drawings involves recording the types and quantities of components required for construction and included in the design drawings. The construction site support system 10 includes a terminal device 20 and a server 30.

[0035] The terminal device 20 is, for example, an information terminal device such as a smartphone, tablet terminal, or personal computer used by a user. The user of the terminal device 20 is, for example, a building contractor. The user can use the terminal device 20 to check the type, position, and number of building material symbols included in the design drawings of the building. Specifically, the terminal device 20 includes a communication unit 21, an information processing unit 22, a memory unit 23, an operation reception unit 24, and a display unit 25.

[0036] The communication unit 21 is a communication circuit (i.e., a communication module) that enables the terminal device 20 to communicate with the server 30 via the public network 50. The communication performed by the communication unit 21 is, for example, wireless communication. There are no particular limitations on the communication standard of the communication performed by the communication unit 21.

[0037] The information processing unit 22 performs information processing and the like to present the building material symbol extraction results to the user. The information processing unit 22 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the information processing unit 22 are realized, for example, by the microcomputer or processor constituting the information processing unit 22 executing a computer program stored in the storage unit 23. Specifically, the information processing unit 22 includes an acquisition unit 221 and a control unit 222.

[0038] The acquisition unit 221 acquires the results of picking out the building material symbols included in the design drawings picked up by the server 30 .

[0039] The control unit 222 executes information processing and the like for presenting the results of picking out the building material symbols acquired by the acquisition unit 221 to the user.

[0040] The storage unit 23 is a storage device that stores various data and computer programs executed by the information processing unit 22. The computer programs stored in the storage unit 23 include a dedicated application program for presenting the building material symbol extraction results to the user. The storage unit 23 is realized, for example, by a semiconductor memory.

[0041] The operation reception unit 24 receives user operations and is realized by, for example, a mouse, a keyboard, or a touch panel.

[0042] The display unit 25 displays an image and is realized by a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel.

[0043] The server 30 is a device that performs information processing to extract the positions and numbers of building material symbols included in the design drawings of a building, and is realized by, for example, a computer. Specifically, the server 30 includes a communication unit 31, an information processing unit 32, and a storage unit 33.

[0044] The communication unit 31 is a communication circuit (i.e., a communication module) that enables the server 30 to communicate with the terminal device 20 via the public network 50. The communication performed by the communication unit 31 is, for example, wireless communication. There are no particular limitations on the communication standard of the communication performed by the communication unit 31.

[0045] The information processing unit 32 performs information processing to extract building material symbols included in the design drawings and count the number of them. The information processing unit 32 is realized, for example, by a microcomputer, but may also be realized by a processor. The functions of the information processing unit 32 are realized, for example, by the microcomputer or processor constituting the information processing unit 32 executing a computer program stored in the storage unit 33. Specifically, the information processing unit 32 includes an acquisition unit 321, a detection unit 322, a calculation unit 323, and an output unit 324.

[0046] The acquisition unit 321 acquires the drawing information 41, page number information, and the like from the terminal device 20.

[0047] The detection unit 322 extracts building material symbols included in the design drawings based on the drawing information 41 .

[0048] The calculation unit 323 calculates the number of building material symbols based on the positions of the building material symbols picked up by the detection unit 322.

[0049] The output unit 324 transmits the results of the building material symbol extraction obtained by the detection unit 322 and the calculation unit 323 to the terminal device 20.

[0050] The storage unit 33 is a storage device that stores the drawing information 41 acquired by the acquisition unit 321, the picking result information of the building material symbol picking executed by the detection unit 322, the computer program executed by the information processing unit 32, etc. The storage unit 33 may also store building material symbol information 43. The computer programs stored in the storage unit 33 include a dedicated application program that causes the information processing unit 32 to present the positions and numbers of building material symbols included in the design drawing. The storage unit 33 is realized, for example, by a semiconductor memory.

[0051] The drawing information 41 is information used in the construction of a building. The drawing information 41 includes design drawings and legend symbol information.

[0052] A design drawing is a floor plan used in the construction of a building. Design drawings are created, for example, using a CAD system. FIG. 2 is a schematic diagram of a design drawing 41a according to an embodiment. As shown in FIG. 2, the design drawing 41a is a floor plan showing the floor plan of a building, the types of building material symbols 60 in the building, and the locations of construction equipment corresponding to the building material symbols 60. Locations where the same building material symbol 60 is drawn indicate that the same construction equipment will be placed. In FIG. 2, building material symbols 60a to 60f are building material symbols indicating automatic fire alarms. Note that a design drawing has multiple pages, and FIG. 2 shows one page of the design drawing. In a design drawing, for example, one floor of a building is illustrated on one page. In other words, multiple pages show the floor plan of each floor of the building and the location of construction equipment.

[0053] Legend symbol information is information indicating the type of building material symbol 60 included in the design drawing. FIG. 3 is a diagram showing legend symbol information 41b in the design drawing according to the embodiment. As shown in FIG. 3, legend symbol information 41b is a list of the types of building material symbols 60 included in the design drawing shown in FIG. 2. In FIG. 3, building material symbols 60a to 60f are building material symbols indicating automatic fire alarms. For example, building material symbol 60c, which has a square with the letter "S" inside and a rectangle with its width in the longitudinal direction adjacent to the upper side of the square and "Ex" written in the lower right corner, is a building material symbol representing the wiring device for an automatic fire alarm with a "photoelectric spot-type detector, type 3, non-accumulating head" and a "quick-connect detector base with confirmation light (without connector)." Therefore, in the design drawing 41a, the location where building material symbol 60c is drawn indicates that a set of automatic fire alarms, which are ``photoelectric spot type detector, three-type head, non-accumulation type,'' and wiring equipment for an automatic fire alarm, which is ``quick-connect detector base with confirmation light (no connector),'' will be installed.

[0054] In addition, the legend symbol information 41b may include some types of building material symbols 60 included in the design drawing 41a, or may include types of building material symbols 60 that are not included in the design drawing.

[0055] The picking result information is information indicating the picking results of the number and positions of building material symbols 60 included in the design drawings by the server 30. The picking result information includes marker position information and marker shape information. The picking result information is detected by the detection unit 322 and then stored in the memory unit 33. Fig. 4 is a diagram showing picking result information 42 in the construction site support system 10 according to the embodiment. (a) of Fig. 4 is a diagram showing marker position information in the construction site support system 10 according to the embodiment. (b) of Fig. 4 is a diagram showing marker shape information in the construction site support system 10 according to the embodiment.

[0056] As shown in (a) of FIG. 4, the marker position information is information in which a "marker number," a "drawing number," and the coordinates of the marker are associated with the marker attached to the extracted building material symbol. The "marker number" is a number assigned to each marker. Each marker is assigned a unique number. The "drawing number" is the page number of the design drawing containing the marker. Generally, one page of a design drawing depicts the floor plan of one floor. In other words, markers with the same "drawing number" are markers attached to building material symbols on the same floor. "x," "y," "w," and "h" are information indicating the coordinates of the marker. "x" is the x-coordinate of the center point of the marker on the design drawing, "y" is the y-coordinate of the center point of the marker on the design drawing, "w" is the width of the marker's circumscribing rectangle in the x-axis direction, and "h" is the width of the marker's circumscribing rectangle in the y-axis direction. Note that the way in which the marker coordinates are expressed is merely an example and is not limited here. For example, a marker with a "marker number" of "1" is included in the design drawing of the page with a "page number" of "002," and the coordinates of the center point of the marker are "(80, 66)," and the size is "10" wide and "10" high.

[0057] As shown in (b) of FIG. 4, the marker shape information is information in which a "marker number" and a "marker shape" are associated with a marker attached to the picked-up building material symbol 60. The "marker shape" indicates the shape of the marker corresponding to the picked-up building material symbol 60. For example, the "marker shape" of a marker with a "marker number" of "1" is "□". If the "marker shapes" of multiple markers are the same, this indicates that the construction site support system 10 has picked out the building material symbols 60 as being the same.

[0058] The construction site support system 10 performs picking of building material symbols 60 based on the drawing information 41 and outputs picking result information 42. FIG. 5 is a diagram showing picking legend symbol information 70 in the construction site support system according to an embodiment. As shown in FIG. 5, the picking legend symbol information 70 is information indicating the shape of the marker 61 associated with each building material symbol 60 included in the legend symbol information 41b. In other words, the picking legend symbol information 70 indicates the correspondence between the building material symbols 60 and the shapes of the markers 61. For example, the "marker shape" of the marker 61a associated with the building material symbol 60a indicating "Do not handle" is a "pentagon." Furthermore, for example, the "marker shape" of the marker 61c associated with the building material symbol 60c indicating the automatic fire alarm "Photoelectric spot type detector, type 3, non-accumulating head" and the automatic fire alarm wiring device "Quick-connect detector base with check light (without connector)" is a "star-shaped octagon."

[0059] As shown in Figure 6, the picked-out design drawing 71 is a drawing showing how the building material symbols 60a to 60f included in the design drawing 41a shown in Figure 2 have been picked out by the construction site support system 10 and markers 61a to 61f corresponding to the building material symbols 60a to 60f have been added.

[0060] The building material symbol information 43 is information that includes information that associates the building material symbol 60 with the price of the construction equipment indicated by the building material symbol 60. At this time, by referring to the building material symbol information 43 and adding it up with the type and number of building material symbols 60 indicated by the picking result information 42, it is possible to calculate the total cost of purchasing the construction equipment indicated by the building material symbol 60 included in the building. The building material symbol information 43 may also include information that associates the building material symbol 60 with the product number of the construction equipment indicated by the building material symbol 60. At this time, by referring to the building material symbol information 43, it is possible to present detailed information that indicates the characteristics and performance of the construction equipment indicated by the building material symbol 60.

[0061] [Operation] Next, a description will be given of the operation of the construction site support system 10 according to the embodiment. The construction site support system 10 can simultaneously display, for a specific building material symbol included in a blueprint of a building, the number of symbols included in one page of the blueprint and the number of symbols included in the entire blueprint.

[0062] The operation of such a construction site support system 10 will be described. FIG. 7 is a sequence diagram showing the operation of the construction site support system 10 according to the embodiment. FIG. 8 is a flowchart showing the operation of the construction site support system 10 according to the embodiment, that is, a flowchart corresponding to the sequence diagram of FIG. 7. (a) of FIG. 8 is a flowchart showing the operation of the terminal device 20 in the construction site support system 10 according to the embodiment, that is, the operation of the terminal device 20 in the sequence diagram of FIG. 7. (b) of FIG. 8 is a flowchart showing the operation of the server 30 in the construction site support system 10 according to the embodiment, that is, the operation of the server 30 in the sequence diagram of FIG. 7. Note that in FIGS. 7, 8(a) and 8(b), similar steps are given the same reference numerals, and redundant explanations will not be given.

[0063] First, the acquisition unit 221 of the terminal device 20 acquires the user's building material symbol pick-up command accepted by the operation acceptance unit 24 (S101). Next, the control unit 222 of the terminal device 20 transmits the acquired building material symbol pick-up command to the server 30 via the communication unit 21, the public network 50, and the communication unit 31 (S102).

[0064] The building material symbol picking command is a command for executing picking up of building material symbols 60 included in design drawings of a building. The building material symbol picking command includes drawing information 41. Note that the server 30 may store the design drawings in advance in the storage unit 33, and in this case, the building material symbol picking command does not need to include the design drawings.

[0065] Next, the detection unit 322 of the server 30 executes picking up of the building material symbol 60 based on the acquired building material symbol picking up command (S103). The detection unit 322 determines the shapes of markers 61a to 61f corresponding to the building material symbols 60a to 60f as shown in Fig. 5 based on the design drawing 41a shown in Fig. 2 and the legend symbol information 41b shown in Fig. 3, and attaches a marker 61 of a shape corresponding to the building material symbol 60 included in the design drawing as shown in Fig. 6. The picking up result is stored in the storage unit 33 as picking up result information 42.

[0066] When the picking up of the building material symbols is completed, the output unit 324 transmits the picking up results to the terminal device 20 via the communication unit 31, the public network 50, and the communication unit 21 (S104). The picking up results are, specifically, information indicating the shape of the marker 61 and information indicating the coordinates of the marker 61.

[0067] The acquisition unit 221 of the terminal device 20 acquires the user's page number input operation accepted by the operation acceptance unit 24 (S105). The page number input operation is an operation for inputting the page number of the design drawing for which the user wishes to check the results of the building material symbol extraction. For example, when the user wishes to check the design drawing for the first floor, the user inputs the page number of the corresponding design drawing using the operation acceptance unit 24.

[0068] The control unit 222 of the terminal device 20 transmits the acquired page number information to the server 30 via the communication unit 21, the public network 50, and the communication unit 31 (S106).

[0069] The calculation unit 323 of the server 30 counts the number of markers 61a-61f on the specified page and the number of markers 61a-61f on the entire design drawing based on the page number information acquired by the acquisition unit 321 (S107). The calculation unit 323 identifies the "marker numbers" of the markers 61 included on the specified page by referencing the "page number" of the marker position information shown in FIG. 4A stored in the storage unit 33. Next, the calculation unit 323 calculates the number of "marker shapes" corresponding to the identified "marker numbers" by referencing the marker shape information shown in FIG. 4B stored in the storage unit 33. This calculates the number of each "marker shape" included on the specified page. At the same time, the calculation unit 323 calculates the number of each "marker shape" on the entire design drawing by referencing the marker shape information shown in FIG. 4B.

[0070] When the calculation unit 323 of the server 30 calculates the number of markers, the output unit 324 transmits the calculated count result to the terminal device 20 via the communication unit 31, the public network 50, and the communication unit 21 (S108).

[0071] The control unit 222 of the terminal device 20 displays the markers 61 on the display unit 25 by superimposing them on the building material symbols 60 included in the design drawings stored in the memory unit 23 based on the information and marker position information acquired by the acquisition unit 221 in step S104 and the count result acquired in step S108, and also displays the pick-up legend symbol information 70 and the count result of the markers 61 together (S109). FIG. 9 is a diagram showing an example of a screen display related to the operation of the construction site support system 10 according to the embodiment. As shown in FIG. 9, the display unit 25 displays the pick-up legend symbol information 70 and the pick-up design drawings 71. Furthermore, the pick-up legend symbol information 70 also displays the number of markers 61 corresponding to each "marker shape." For example, the number of markers is displayed as a fraction, with the numerator 62 indicating the number of markers 61 on the displayed drawing and the denominator 63 indicating the number of markers 61 on the entire design drawing. For example, the "marker shape" of the marker 61c associated with the building material symbol 60c representing the automatic fire alarm "Photoelectric Spot Type Detector, Type 3, Head, Non-Storage Type" and the automatic fire alarm wiring device "Quick-Connect Detector Base with Check Light (without Connector)" is a "star-shaped octagon." Since there are five markers 61c on the page shown in Figure 9 and 19 on the design drawing for the entire building, the numerator 62 of the fraction displayed below the marker 61c is 5 and the denominator 63 is 19. "5 / 19" is displayed below the marker 61c. This allows the user to simultaneously check the number of building material symbols 60 included in the design drawing 41a, both for each floor and for the entire building. This significantly reduces the time required for the extraction process.

[0072] Next, it is determined whether or not a change instruction has been issued by the user (S115). The change instruction is, for example, an instruction by the user to change the page number of the design drawing displayed on the display unit 25. The change instruction may also be, for example, an instruction by the user to move the marker 61 in order to check the building material symbol 60 to which the marker 61 is attached. The change instruction may also be, for example, an instruction by the user to add or delete a marker 61 in order to correct an error in the picking performed by the detection unit 322, or an instruction to change the "marker shape" of the marker 61.

[0073] Next, if there is a change instruction from the user (Yes in S115 of FIG. 8 ), the acquisition unit 221 of the terminal device 20 acquires the change instruction from the user via the operation acceptance unit 24 (S110). When the acquisition unit 221 acquires the change instruction from the user, the information processing unit 22 transmits the change instruction to the server 30 via the communication unit 21, the public network 50, and the communication unit 31 (S111).

[0074] When the acquisition unit 321 acquires the change instruction from the user, the calculation unit 323 counts the number of markers 61 included in the specified page and the number of markers 61 in the entire design drawing (S112) based on the change instruction acquired by the acquisition unit 321. For example, if the change instruction from the user is an instruction to change the "page number" from "001" to "002," the calculation unit 323 counts the number of markers 61 associated with the "page number" of "002."

[0075] When the calculation unit 323 of the server 30 calculates the number of markers 61, the output unit 324 transmits the calculated count result to the terminal device 20 via the communication unit 31, the public network 50, and the communication unit 21 (S113).

[0076] The control unit 222 of the terminal device 20 displays the pick-up legend symbol information 70 and the pick-up design drawing 71 on the display unit 25 based on the marker shape information and marker position information acquired by the acquisition unit 221 in step S104 and the counting results acquired in step S113, and displays the counting results of markers 61a to 61f together with the pick-up legend symbol information 70 (S114).

[0077] FIG. 10 is a diagram showing another example of a screen display relating to an example of the operation of the construction site support system 10 according to the embodiment. Compared to the design drawing of the page shown in FIG. 9 , the design drawing of the page shown in FIG. 10 has one additional building material symbol 60b with "AD" written inside a rectangle. The building material symbol 60b is a building material symbol indicating an "address adapter," and the "marker shape" of the associated marker 61b is a "clover." Three markers 61b are added to the design drawing shown in FIG. 10 , and eight are added to the entire design drawing. Therefore, the numerator 62 of the fraction displayed below the marker 61b is 3, and the denominator 63 is 8. Here, two markers 61b are added to the design drawing shown in FIG. 9 , so the numerator 62 of the fraction displayed below the marker 61b in FIG. 9 is 2, and the denominator 63 is 8.

[0078] 10 has five markers 61c and the entire building design drawing has 19 markers 61c, so the numerator 62 of the fraction displayed below the markers 61c is 5 and the denominator 63 is 19. In other words, "5 / 19" is displayed below the markers 61c in both FIG. 9 and FIG. 10. It can be seen that the detection unit 322 has picked out that the page displayed in FIG. 9 and the page displayed in FIG. 10 of the design drawing 41a contain the same number of building material symbols 60c. In general, the number of specific building material symbols on each floor of a building is often the same, so the user can predict that there is a high probability that the picking out of the building material symbols 60c was performed correctly.

[0079] Thereafter, the acquisition unit 221 of the terminal device 20 repeats the procedures of steps S111 to S114 each time it acquires a change instruction from the user via the operation acceptance unit 24 until there are no more change instructions from the user (No in S115 of FIG. 8).

[0080] At least one of the storage unit 23 of the terminal device 20 and the storage unit 33 of the server 30 may store the building material symbol information 43. In this case, the construction cost can be calculated by adding up the number of markers 61 and the price of the corresponding construction equipment.

[0081] The server 30 does not have to transmit the picking results to the terminal device 20 in step S104. In this case, when the server 30 transmits the count results to the terminal device 20 in steps S108 and S113, the server 30 may also transmit the picking results for the design drawings of the "page numbers" to be displayed on the display unit 25. This allows the control unit 222 of the terminal device 20 to display, on the display unit 25, markers superimposed on the design drawings stored in the memory unit 23 based on the picking results and count results acquired by the acquisition unit 221, and to display the legend symbol information together with the count results of the markers.

[0082] In this embodiment, the calculation unit 323 of the server 30 counts the number of markers (S107 and S112), but the information processing unit 22 of the terminal device 20 may also count the number of markers based on the result of the picking up obtained in step S104. In this case, the terminal device 20 can execute all steps from step S105 onwards.

[0083] By this operation, the construction site support system 10 can simultaneously display the number of specific building material symbols included in a building design drawing, both the number of symbols included in one page of the drawing and the number of symbols included in the entire drawing, allowing the user to greatly improve the efficiency of the picking work with simple operations and significantly reduce the time required for the picking work.
