More specifically, the CPU 12 acquires various door shape patterns stored in the door DB 140 described in Figure 5, and extracts the door area shown in the architectural plan by pattern matching as described in Figure 7. Next, the facility drawing creation device 10 extracts a room area (step S6). More specifically, the CPU 12 extracts a closed area that includes the door area and has a predetermined area or more as a room area as described in Figure 8. Next, the facility drawing creation device 10 places an object indicating an entrance and exit facility (step S8). More specifically, the CPU 12 places an object SC representing the entrance/exit facility on the architectural floor plan in correspondence with the door area provided in the extracted room area, as described in FIG. 9. Next, the facility drawing creation device 10 outputs an object representing the placed entrance/exit facility (step S10). More specifically, the CPU 12 displays the placed object SC on the architectural floor plan on the display device 20. Then, the facility drawing creation device 10 ends the process (END).

According to the equipment drawing creation device 10 according to the first embodiment, there is no need to manually place objects indicating entrance and exit equipment. The equipment drawing creation device 10 extracts door areas and places objects indicating entrance and exit equipment in room areas that include the extracted door areas, so that it is possible to automatically place them on an architectural floor plan in a simple manner. This allows the operator to easily create equipment drawings.

As an example, a case will be described in which the facility drawing creation device 10 is connected to a server 2 and acquires architectural plan data from the server 2, but the device that acquires the architectural plan data is not limited to the server 2. For example, a configuration may be adopted in which a scanner is provided instead of the server 2. The scanner may optically scan an architectural plan printed on a paper medium and acquire architectural plan data that is an image. The facility drawing creation device 10 may acquire architectural plan data that is an image of the architectural plan from the scanner.

(First Modification of First Embodiment)
In the first modification of the first embodiment, a case will be described in which an object indicating an entrance/exit facility is arranged in accordance with the type of the extracted door area. As described in FIG. 5, there are a plurality of types of door shape patterns depending on the purpose. For a certain door shape, it is desirable to arrange the entrance/exit facility in accordance with the structure of the door shape. For example, in the case of a single swinging door, only one side of the door moves to open and close. The operation of opening and closing the door is easier if the entrance/exit facility such as a card reader is arranged in a location close to the side where the door moves. In other words, the position on the left or right side where the entrance/exit facility such as a card reader is arranged when facing the door may be determined in accordance with the type of the door area.

The entrance/exit equipment placement unit 33 places an object representing the entrance/exit equipment on the architectural floor plan in accordance with the type of the extracted door area. More specifically, if the extracted door area is a single-leaf door, the entrance/exit equipment placement unit 33 places the object of the entrance/exit equipment so that it is on the right side when facing the door. If the extracted door area is a parent-child door, the entrance/exit equipment placement unit 33 places the object of the entrance/exit equipment on the side closer to the parent side. For other door areas, it is also possible to set the placement position of the entrance/exit equipment in advance in accordance with the type of door area.

The equipment drawing creation device 10 according to the first modified example of the first embodiment extracts door areas and places objects indicating entrance and exit equipment in appropriate positions for the type of extracted door area, making it possible to automatically place them on the architectural floor plan in a simple manner. This allows the operator to easily create equipment drawings.

(Modification 2 of the First Embodiment)
In a second modification of the first embodiment, a case will be described in which objects indicating entrance and exit facilities are arranged by estimating traffic lines.

11 is a diagram for explaining the estimation of a flow line in an architectural plan according to the second modification of the first embodiment. Referring to FIG. 11, the facility drawing creation device 10 estimates a flow line based on an extracted door area on the architectural plan. More specifically, the flow line estimation unit 37 identifies a room area serving as an entrance on the architectural plan based on the facility part DB 146. The flow line estimation unit 37 judges whether or not a staircase, an elevator, an escalator, or the like is provided in the room area. When the flow line estimation unit 37 judges that a staircase, an elevator, an escalator, or the like is provided in the room area, it identifies the room area as a room area serving as an entrance. As an example, the flow line estimation unit 37 identifies a room area RA in which a staircase and an elevator are provided as a room area serving as an entrance to other floors of the building. The flow line estimation unit 37 estimates a flow line starting from the identified room area serving as an entrance.

The traffic flow estimation unit 37 estimates a traffic flow path from room area RA to room area RB via door area DA, from room area RB to room area RC via door area DB, from room area RC to room area RE via door area DD, from room area RE to room area RD via door area DE, from room area RD to room area DB via door area DC, and from room area DB to room area RA via door area DA.

The traffic flow estimation unit 37 estimates a traffic flow path from room area RA to room area RB via door area DA, from room area RB to room area RD via door area DC, from room area RD to room area RE via door area DE, from room area RE to room area RC via door area DD, from room area RC to room area DB via door area DB, and from room area DB to room area RA via door area DA.

The entrance/exit facility placement unit 33 places objects representing entrance/exit facilities based on the traffic flow paths estimated by the traffic flow estimation unit 37.

Figure 12 is a diagram illustrating a specific process flow for arranging entrance/exit facilities according to the second variation of the first embodiment. Referring to Figure 12, the equipment drawing creation device 10 identifies a room area that will serve as an entrance/exit (step S20). More specifically, the CPU 12 determines whether or not stairs, an elevator, an escalator, or the like is provided in the room area. If the CPU 12 determines that stairs, an elevator, an escalator, or the like is provided in the room area, it identifies the room area as a room area that will serve as an entrance/exit.

Next, the equipment drawing creation device 10 places an object indicating an entrance/exit facility in a door area provided in the room area closer to the room area serving as the entrance/exit (step S22). More specifically, the CPU 12 places an object indicating an entrance/exit facility in the room area closer to the door area, starting from the room area serving as the entrance/exit. The CPU 12 places an object indicating an entrance/exit facility in the room area RA in correspondence with the door area DA. The CPU 12 places an object indicating an entrance/exit facility in the room area RB in correspondence with the door areas DB and DC. The CPU 12 places an object indicating an entrance/exit facility in the room area RC in correspondence with the door area DD. The CPU 12 places an object indicating an entrance/exit facility in the room area RD in correspondence with the door area DE. The equipment drawing creation device 10 then ends the process (return).

The facility diagram creation device 10 places objects representing entrance and exit facilities based on estimated traffic flow routes, making it possible to easily place highly convenient entrance and exit facilities that match the traffic flow routes.

(Embodiment 2)
In the second embodiment, the setting of security information for entrance/exit facilities will be described.

The adjacent room table generation unit 42 generates an adjacent room table based on the extracted room area and the extracted door area.

Figure 13 is a diagram illustrating an adjacent room table according to embodiment 2. Referring to Figure 13, door area DA is adjacent to room areas RA and RB. Door area DB is adjacent to room areas RB and RC. Door area DC is adjacent to room areas RB and RD. Door area DD is adjacent to room areas RC and RE. Door area DE is adjacent to room areas RD and RD. The adjacent room table makes it possible to grasp the relationship between each room area and the door area.

The security setting unit 38 according to the second embodiment sets security information for the entrance/exit facilities provided in each room area based on the generated adjacent room table. The security setting unit 38 identifies the room area that serves as an entrance/exit on the architectural floor plan. More specifically, the security setting unit 38 determines whether or not stairs, elevators, escalators, etc. are provided in the room area. If stairs, elevators, escalators, etc. are provided in the room area, the security setting unit 38 identifies the room area as a room area that serves as an entrance/exit.

The security setting unit 38 increases the security level for the entry/exit equipment to be set according to the number of door areas up to the room area that serves as the entrance/exit. As an example, the security setting unit 38 identifies the room area RA that serves as the entrance/exit.

FIG. 14 is a diagram for explaining the setting of security information according to the second embodiment. Referring to FIG. 14, the security setting unit 38 sets the security level of the entrance/exit equipment of the door area DA provided between the room area RA and the adjacent room area RB to SR0. The security setting unit 38 sets the security level of the entrance/exit equipment of the door area DB provided between the room area RB and the adjacent room area RC to SR1 by increasing it by one according to the number of door areas from the reference room area. The security setting unit 38 sets the security level of the entrance/exit equipment of the door area DC provided between the room area RB and the adjacent room area RD to SR1 by increasing it by one according to the number of door areas from the reference room area. The security setting unit 38 sets the security level of the entrance/exit equipment of the door area DD provided between the room area RC and the adjacent room area RE to SR2 by increasing it by one according to the number of door areas from the reference room area. The security setting unit 38 increases the security level of the entrance/exit equipment of the door area DE provided between the room area RD and the adjacent room area RE by one according to the number of door areas from the reference room area, and sets it to SR2.

The facility drawing creation device 10 can set the security level for entrance and exit facilities in a simple manner using this setting method.

(Embodiment 3)
In the third embodiment, the creation of a system diagram of entrance/exit facilities will be described. Fig. 15 is a diagram for explaining the creation of a system diagram of entrance/exit facilities according to the third embodiment. Referring to Fig. 15, a system diagram of entrance/exit facilities on a plurality of floors is shown. As an example, a system diagram of entrance/exit facilities on the second floor and the first floor is shown. The entrance/exit facilities described in Fig. 9 are assumed to be on the second floor.

The facility drawing creation device 10 creates a system diagram of the entrance/exit facilities based on the number of objects representing the entrance/exit facilities placed by the entrance/exit facilities placement unit 33. The placement information of the entrance/exit facilities placed by the entrance/exit facilities placement unit 33 on each floor is stored in the HDD 14.

The system diagram creation unit 36 obtains the number of entrance/exit equipment arranged on each floor from the HDD 14. The system diagram creation unit 36 creates a system diagram based on the arrangement information of the entrance/exit equipment stored in the HDD 14.

The system diagram creation unit 36 acquires placement information for objects SC0 to SC4, which represent entrance and exit facilities, on the second floor.

The system diagram creation unit 36 creates a system diagram that connects the objects SC0 to SC4, which represent the entrance and exit facilities, together with the controller installed on the second floor.

The system diagram creation unit 36 creates a similar system diagram based on the number of entrance/exit facilities located on the first floor in a similar manner.

The facility diagram creation device 10 identifies the number of entry/exit facilities by the placement of objects that represent the facilities, and can easily create a system diagram based on the identified number.

Each entrance/exit facility includes an electric lock KY and a card reader CR. Therefore, the facility drawing creation device 10 may display an electric lock KY0 and a card reader CR0 in association with an object SC0 representing the entrance/exit facility.

The operator can easily understand the configuration of the entry/exit equipment that is placed using this method through the system diagram. In addition, the equipment drawing creation device 10 can easily manage each entry/exit equipment by assigning an identification number to each placed entry/exit equipment.
