Description

This disclosure relates to a design support device for disaster prevention equipment that displays the state in which disaster prevention equipment is installed in a fire-prevention facility as a 3D layout diagram.

Automatic fire alarm systems are disaster prevention equipment that are equipped with receivers, transmitters, repeaters, audio devices, sensors, etc., and protect people inside buildings and other facilities that are subject to fire prevention measures from fires (see, for example, Non-Patent Document 1).

In an automatic fire alarm system, a detector detects heat or smoke and sends a fire signal to a receiver. The receiver that receives the fire signal issues an alarm and activates an audio device depending on the location of the fire, informing people in the fire-prevention facility that a fire has occurred.

In recent years, there have been many news reports of fires at castles, public facilities, factories, multi-use buildings, etc. Therefore, for example, when formulating a business continuity plan, it is important for the person in charge or manager of the fire-prevention facility (i.e., the user of the disaster prevention equipment) to accurately understand whether the current disaster prevention equipment is appropriate, whether there are any areas that need improvement, and what kind of disaster prevention equipment should be installed in a new fire-prevention facility.

On the other hand, from the standpoint of manufacturers of disaster prevention equipment, such as automatic fire alarm systems, it is important to propose to existing and new users disaster prevention equipment that is suitable for the facilities that each user needs to protect against fires.

For manufacturers, being able to visually and accurately grasp the layout of fire prevention equipment suited to each user's fire-prevention target facility will not only improve design efficiency but also serve as a useful sales tool.

In addition, customers can visually check the layout, allowing them to gain a deeper understanding of the disaster prevention equipment proposed by the manufacturer.

In other words, if disaster prevention equipment customized for each customer could be visually inspected at the desired location in the fire-prevention facility, it could be used as a sales tool for manufacturers and provide useful information for both users and manufacturers.

The present disclosure has been made to solve the above problems, and aims to provide a design support device for disaster prevention equipment that can provide the user with visual information on disaster prevention equipment suited to the facility to be protected against fire for each desired location.

The design support device for disaster prevention equipment according to the present disclosure includes a model creation unit that creates a 3D model corresponding to a fire-prevention facility, a layout drawing creation unit that creates a 3D layout drawing in which disaster prevention equipment to be installed in the fire-prevention facility is added to the 3D model, and a display control unit that displays the 3D layout drawing based on an operational input that specifies the line of sight and cross section.

According to the present disclosure, it is possible to obtain a design support device for disaster prevention equipment that can provide information that allows the user to visually grasp disaster prevention equipment suitable for the facility to be protected against fire for each desired location.

FIG. 1 is a first explanatory diagram of a 3D model and a 3D layout drawing obtained using a design support device for disaster prevention equipment according to a first embodiment of the present disclosure. FIG. 2 is a second explanatory diagram of a 3D model and a 3D layout drawing obtained using the design support device for disaster prevention equipment according to the first embodiment of the present disclosure. FIG. FIG. 1 is an explanatory diagram illustrating a method of utilizing a design support device for disaster prevention equipment in a first embodiment of the present disclosure.

Hereinafter, preferred embodiments of the design support device for disaster prevention equipment of the present disclosure will be described with reference to the drawings.
The design support device for disaster prevention equipment disclosed herein has a technical feature of providing information on disaster prevention equipment suitable for different fire prevention facilities for each customer in the form of a 3D layout drawing when viewed from a desired line of sight and a desired cross section based on operational input.

Embodiment 1.
1 is a functional block diagram of a design support device for disaster prevention equipment according to a first embodiment of the present disclosure. A design support device 10 for disaster prevention equipment according to the first embodiment is configured to include a model creation unit 11, a layout drawing creation unit 12, a display control unit 13, and a display unit 14.

The design support device 10 for disaster prevention equipment according to the first embodiment has the configuration shown in FIG. 1 and can provide information on the arrangement of disaster prevention equipment configured to suit the fire-prevention target facilities of each user in the form of a 3D layout diagram.

In particular, the disaster prevention equipment design support device 10 can display a 3D layout diagram of a desired cross section viewed from a desired line of sight based on operational input. Here, the functions of each component shown in FIG. 1 will be described in detail.

The model creation unit 11 has a function for creating 3D models corresponding to individual fire prevention facilities for each customer. Traditionally, drawings related to automatic fire alarm systems were created and managed as floor plans. However, with the spread of 3D CAD, there are increasing opportunities to create 3D drawings rather than floor plans from the design stage. Therefore, the designer of the automatic fire alarm system uses the model creation unit 11 to create 3D models corresponding to individual fire prevention facilities for each customer.

When creating a 3D model, the 3D model data created by a building design company or construction company may be used as is, or it may be used after processing or data conversion. This also falls under the category of creating a 3D model.

The layout drawing creation unit 12 has a function of creating a 3D layout drawing by adding disaster prevention equipment to be installed in the fire prevention facility to the 3D model created by the model creation unit 11. The designer of the automatic fire alarm system uses the layout drawing creation unit 12 to place disaster prevention equipment such as fire detectors on the 3D model created by the model creation unit 11, and creates an individual 3D layout drawing for each client.

The display control unit 13 has a function of converting the 3D layout drawing created by the layout drawing creation unit 12 into data that can be displayed by software with functions suitable for 3D display, such as 3D viewer software, based on an operational input that specifies the line of sight and cross section, and displaying the data on the display unit 14.

Therefore, a user of the disaster prevention equipment design support device 10 can set a desired line of sight and a desired cross section as an operational input to the display control unit 13, and be provided with information on a 3D layout diagram when the desired cross section is viewed from the desired line of sight.

This type of input can be done not only by the designer, but also by a salesperson or a customer. In other words, after the designer creates an individual 3D layout drawing for each customer, any user who wants to receive information on the 3D layout drawing when viewed from a desired line of sight and a desired cross section can input the operation.

The display control unit 13 can also perform print output to form a cross-sectional model corresponding to the 3D layout drawing using an externally connected three-dimensional printer 20 based on the line of sight and the cross-section set based on the operational input.

In other words, as an optional function, a 3D printer 20 can be used to create a 3D model for each floor or for a specific fire compartment. The created 3D model can then be used for design reviews, presentations to clients, etc.

Figure 2 is a first explanatory diagram of a 3D model and a 3D layout diagram obtained using the design support device 10 for disaster prevention equipment according to the first embodiment of the present disclosure. Figure 2 illustrates two diagrams, Figure 2 (A) and Figure 2 (B), for a case in which the fire prevention facility 100 is a three-story, approximately rectangular parallelepiped structure.

Figure 2 (A) shows a state in which a desired line of sight D1 and a desired cross section X-X' have been set as operational input for the fire prevention facility 100. Figure 2 (B) shows a 3D layout diagram of the desired cross section X-X' as viewed from the desired line of sight D1 based on such operational input.

In the 3D layout diagram in FIG. 2(B), the three-story fire-prevention facility 100 is sliced along the desired cross section X-X' and shown as a 3D display seen from the desired line of sight D1. By utilizing the model creation unit 11 and the layout diagram creation unit 12, the designer can install disaster prevention equipment in the desired positions for each fire compartment 110 within the fire-prevention facility 100 and create a 3D layout diagram.

Furthermore, by visually viewing such a 3D layout diagram, not only designers but also salesmen and customers can easily recognize where the disaster prevention equipment 200 is installed for each fire compartment 110.

Figure 3 is a second explanatory diagram of a 3D model and a 3D layout diagram obtained using the design support device 10 for disaster prevention equipment according to the first embodiment of the present disclosure. Figure 3 illustrates two diagrams, Figure 3(A) and Figure 3(B), in which a line of sight and a cross section different from those in Figure 2(A) are set for the fire prevention facility 100 shown in Figure 2(A) above.

Figure 3 (A) shows a state in which a desired line of sight D2 and a desired cross section Y-Y' have been set as operational input for the fire prevention facility 100. Figure 3 (B) shows a 3D layout diagram of the desired cross section Y-Y' as viewed from the desired line of sight D2 based on such operational input.

In the 3D layout diagram in FIG. 3(B), the three-story fire-prevention facility 100 is sliced along the desired cross section Y-Y' and shown as a 3D display seen from the desired line of sight D2. By utilizing the model creation unit 11 and the layout diagram creation unit 12, the designer can install disaster prevention equipment in the desired positions for each fire compartment 110 in the fire-prevention facility 100, as in FIG. 2 above, and create a 3D layout diagram.

Furthermore, by visually viewing such a 3D layout diagram, not only designers but also salesmen and customers can easily recognize where the disaster prevention equipment 200 is installed for each fire compartment 110.

2 and 3, the display control unit 13 displays the 3D layout diagram using 3D viewer software, and can freely rotate and enlarge the 3D layout diagram to allow a desired area to be viewed from a desired direction. Furthermore, by utilizing the layout diagram creation unit 12, the installation position of the disaster prevention equipment 200 can be changed as necessary.

Therefore, users of the disaster prevention equipment design support device 10 can receive information that allows them to visually grasp the disaster prevention equipment 200 that is suitable for the fire prevention facility 100 for each desired fire compartment 110, as shown in Figures 2 and 3.

The layout drawing creation unit 12 has an optional function of specifying the number, installation location, and type of disaster prevention equipment 200 to be installed for each fire compartment 110 based on preset design parameters for the 3D model created corresponding to the fire-protected facility 100.

Specific examples of design parameters include the following:
Parameter 1: Whether the fire compartment 110 is a fire-resistant structure or not. Parameter 2: Whether the fire compartment 110 has an opening or not. Parameter 3: Floor area of the fire compartment 110. Parameter 4: Ceiling height of the fire compartment 110.

The layout drawing creation unit 12 prestores design rules for identifying the number, installation location, and type of disaster prevention equipment 200 to be installed for each fire compartment 110. Therefore, by having such an optional function, the layout drawing creation unit 12 can provide recommended information regarding the number, installation location, and type of disaster prevention equipment 200 to be installed for each fire compartment 110 by utilizing the design rules based on at least one of these design parameters.

In addition, designers at disaster prevention equipment manufacturers can reduce the amount of equipment design work by utilizing this function, which can automatically identify the number, installation location, and type of disaster prevention equipment 200 to be installed.

The applicant of this application has also filed prior applications (Patent Application Nos. 2023-059692 and 2023-059693) for an invention relating to a fire simulation system that can provide fire simulation results based on a simulation model that is suited to the user's fire-protected facility.

The design support device for disaster prevention equipment according to the first embodiment can obtain fire simulation results corresponding to a 3D layout drawing of disaster prevention equipment suited to the user's fire-protected facilities by utilizing the fire simulation function disclosed in the prior application. As a result, optimal disaster prevention equipment that takes into account the fire simulation results can be provided for each of the user's fire-protected facilities.

As an example of a specific configuration for applying the fire simulation function disclosed in the prior application to the design support device for disaster prevention equipment of the present disclosure, it is possible to provide the layout drawing creation unit 12 and the display control unit 13 with the following additional functions:

In order to execute the fire simulation function, the layout drawing creation unit 12 needs a simulation model construction function having the following additional functions.
- A function to obtain the simulation conditions necessary to perform a fire simulation of a facility subject to fire protection.
A function for creating a 3D layout drawing so as to construct a simulation model that can provide multiple display data for visually checking the fire simulation results based on the simulation conditions.

Furthermore, in order to execute the fire simulation function, the display control unit 13 needs a fire simulation execution function having the following additional functions.
A function to perform a fire simulation using a 3D layout drawing, thereby calculating at least one of the time progression of the fire spread situation and the time progression of the evacuation situation as the fire simulation result, and generate multiple display data based on the calculation results.
A function of displaying on the display unit 14 display data selected in response to an operational input from among a plurality of display data generated as a result of the fire simulation.

In particular, by utilizing the results of fire simulations that take into account firefighting operations using sprinkler systems and fire extinguishers, the system can provide users with optimal disaster prevention equipment for each of their fire-prevention facilities.

In recent years, it has become possible to visually experience 3D models in a virtual space by wearing goggles for viewing. In contrast, the design support device for disaster prevention equipment according to the first embodiment does not require goggles or the like, and allows users to easily check the layout of disaster prevention equipment in three dimensions on a screen.

Furthermore, by utilizing the fire simulation function described above, it is possible to experience evacuation drills that assume a fire has broken out while visually viewing the 3D display, making it possible to carry out effective evacuation drills.

Next, a method of utilizing the design support device 10 for disaster prevention equipment according to the first embodiment will be described. FIG. 4 is an explanatory diagram of a method of utilizing the design support device 10 for disaster prevention equipment according to the first embodiment of the present disclosure.

A designer belonging to the design department 1 at a manufacturer of disaster prevention equipment can create 3D layout drawings by utilizing a disaster prevention equipment design support device 10. The 3D layout drawings created by the designers can be stored in a server 2, allowing the information to be shared by the sales department 3, customers 4, receivers and control panels 5, and the construction and CS department 6.

In other words, the layout diagram creation unit 12 stores the created 3D layout diagram in the server 2, allowing other devices with functions equivalent to those of the display control unit 13 to access the server 2 and display the 3D layout diagram read from the server 2 using 3D viewer software.

The sales department 3 can download the 3D layout drawings stored in the server 2 and use a 3D viewer to check the 3D model of the disaster prevention equipment customized for each customer, enabling them to make sales proposals in a three-dimensional, easy-to-understand way when visiting customers.

Furthermore, when the fire simulation function is used, the sales department 3 can make sales proposals for appropriate disaster prevention equipment customized for each customer, assuming that a fire occurs in various locations.

By accessing the server 2, the customer 4 can obtain 3D display information on the disaster prevention equipment installed in the fire prevention facility 100 as necessary. In addition, by further utilizing the fire simulation function, evacuation drills can be conducted assuming a fire has broken out. In particular, a more realistic evacuation drill can be realized by assuming a situation in which the fire gradually spreads and smoke fills the area.

For example, when the receiver/control panel 5 receives a fire signal from a fire detector, which is a type of disaster prevention device, it can use the 3D layout diagram stored in the server 2 to display the location where the fire detector issued an alarm as a 3D model.

When constructing or maintaining an automatic fire alarm system, the construction/CS department 6 can use the 3D layout diagram displayed on the receiver/control panel 5 to easily check, as 3D visual information, which fire detectors are sounding during inspection and which fire detectors have already been inspected.

The 3D model layout drawing can also be expanded into a 2D floor plan. For example, it can be expanded into a floor plan on a floor-by-floor basis for use in inspections, etc.

As described above, according to the first embodiment, a layout of disaster prevention equipment suited to the user's fire-prevention target facility can be provided as a 3D layout diagram. Furthermore, by storing the 3D layout diagram created by the designer in the server, the 3D layout diagram can be effectively used when and where necessary.
