Description

[Technical Field]

[0001] The present disclosure relates to a display system that aggregates and displays information about disaster prevention equipment installed within a fire monitoring area. [Background technology]

[0002] Relatively large facilities may have fire alarms and display systems installed as disaster prevention equipment. The display systems aggregate and display information about the disaster prevention equipment installed within the facility, and can remotely control the equipment as needed.

[0003] The following display system has been disclosed as such (see, for example, Patent Document 1). The display system according to Patent Document 1 receives location information of fire detectors installed in various locations within a facility. The display system then displays a plan view map showing the floors of the facility, and displays the fire detectors in the correct positions on the plan view map based on the received location information. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-118828 Summary of the Invention [Problem to be solved by the invention]

[0005] If a fire breaks out within a facility, even if personnel from the disaster prevention center head to the scene of the fire, it is likely that they will find it difficult to visually confirm the surrounding situation due to the effects of smoke.

[0006] Therefore, when a fire is reported by the fire receiver, personnel at the disaster prevention center use the display system to check the location of disaster prevention equipment, and remotely control the equipment to report the fire, guide evacuations, and carry out firefighting activities.

[0007] Meanwhile, in order to perform remote control using conventional display systems, including the display system described in Patent Document 1, personnel at the disaster prevention center refer to the displayed contents of a floor plan map. However, simply looking at the floor plan map may not always make it easy to immediately understand the installation locations of disaster prevention equipment or understand the behavior of the disaster prevention equipment when it is in use.

[0008] The present disclosure has been made to solve the above-mentioned problems, and provides a display system that allows information on each disaster prevention equipment located within a fire monitoring area to be easily understood visually from a remote location. [Means for solving the problem]

[0009] The display system of the present disclosure is a display system equipped with a display unit that consolidates and displays information necessary to perform centralized control of a fire monitoring area in which multiple disaster prevention equipment is located, and the display unit is capable of displaying the state in which each disaster prevention equipment is located within the fire monitoring area as a three-dimensional image. [Effects of the Invention]

[0010] According to the present disclosure, a display system can be obtained that allows information about each piece of disaster prevention equipment located within a fire monitoring area to be easily understood visually from a remote location. [Brief explanation of the drawings]

[0012] Preferred embodiments of the display system of the present disclosure will be described below with reference to the drawings. The display system according to the first embodiment of the present disclosure has a technical feature in that it displays information indicating the floors of a facility as a planar map, and also has the function of, by operating an icon, further displaying a three-dimensional image of the inside of the facility as viewed from the position of the icon.

[0013] In addition, in the present disclosure, the displayed three-dimensional image can be created based on BIM (Building Information Modeling) data.

[0014] Embodiment 1 Fig. 1 is a diagram showing a fire receiver and a display system according to the first embodiment of the present disclosure. The fire receiver 1 and the display system 2 shown in Fig. 1 are installed in a disaster prevention center room in a facility that is a fire monitoring area.

[0015] The fire receiver 1 is a management device that remotely controls and manages disaster prevention equipment installed in various locations within a facility. Here, disaster prevention equipment refers to equipment that is activated to notify of a fire outbreak and to limit damage in the event of a disaster, and includes, for example, fire alarm equipment, fire doors, smoke exhaust equipment, emergency broadcast equipment, local sound equipment, and fire extinguishing equipment. When the fire receiver 1 receives a fire occurrence signal from a fire detector, it activates each piece of disaster prevention equipment.

[0016] The display system 2 is a control panel that aggregates and displays information about disaster prevention equipment within the facility. The display system 2 also receives operations from personnel at the disaster prevention center within the facility and transmits commands according to the content of the operations to each piece of disaster prevention equipment via the fire control receiver 1.

[0017] This allows personnel at the facility's disaster prevention center to check alarm operations of sensors and other devices and control disaster prevention equipment.

[0018] 1 shows a configuration in which one fire receiver 1 and one display system 2 are provided, but the configuration may also be such that display systems 2 are provided at various locations within the facility and multiple display systems 2 are connected to one fire receiver 1. Alternatively, the configuration may also be such that fire receivers 1 are provided at various locations within the facility and one or multiple display systems 2 are connected to one another.

[0019] FIG. 2 is a block diagram showing an example of the configuration of the display system 2 shown in FIG.

[0020] The display system 2 includes a display unit 20, an operation unit 21, and a control unit 25.

[0021] The display unit 20 is a high-resolution display that can display characters, symbols, figures, etc. using a GUI (Graphical User Interface), thereby enabling the display unit 20 to provide a large amount of information to disaster prevention center personnel.

[0022] The operation unit 21 is a pointing device such as a mouse or a trackball, or a touch panel arranged on the display surface of the display unit 20. In addition, the operation unit 21 also includes a keyboard that is used during maintenance.

[0023] The control unit 25 includes a calculation processing unit 22, a storage unit 23, and a communication unit 24.

[0024] The arithmetic processing unit 22 includes a central processing unit and a main memory device, and executes software stored in the memory unit 23 .

[0025] The storage unit 23 includes an auxiliary storage device and stores software that is calculated and executed by the calculation processing unit 22 .

[0026] The storage unit 23 also stores a plurality of three-dimensional images 30. The three-dimensional images 30 are image data that represent various locations within the facility in three dimensions, and image data derived from BIM data can be used. Specific examples of the three-dimensional images 30 will be described later.

[0027] The communication unit 24 transmits and receives data to and from the fire control panel 1 via a disaster prevention LAN (Local Area Network).

[0028] FIG. 3 is a planar map displayed by the display system shown in FIG.

[0029] The display system 2 displays a floor selection screen 210 and a plan map 220 on the display unit 20.

[0030] When a disaster prevention center staff member selects a desired floor from the floor selection screen 210, the display system 2 causes the display unit 20 to display a plan view map 220 of the selected floor.

[0031] 3, the display system 2 displays a planar map 220 on which icons 251 to 257 corresponding to a plurality of icons 250 are arranged. Each of the plurality of icons 250 can be pressed, and its position on the planar map 220 indicates the position of a viewpoint that displays a three-dimensional image 30, as will be described later.

[0032] The positions and number of the multiple icons 250 are determined in advance based on the intentions of a person with administrative authority, such as the facility owner, general manager, disaster prevention manager, etc. It is also possible to add or delete icons later.

[0033] Fig. 4 shows a display screen when one of the icons 250 shown in Fig. 3 is selected. Fig. 4 also shows an example in which icon 253 located in room 221 is selected.

[0034] When a disaster prevention center staff member selects one of the icons 251 to 257, the display system 2 displays the three-dimensional image 30 and the direction indicator bar 401. In the example of Fig. 4, a three-dimensional image 301, which is one of the three-dimensional images 30, is displayed.

[0035] As mentioned above, the 3D image 30 can be image data derived from BIM data. Here, BIM data is data that digitizes a structure using a 3D model, and is data that is shared among contractors in each process of the structure's construction planning, design, and construction. BIM data is also used for maintenance management, change management, and configuration management after completion, and whenever design changes or modifications occur to a structure after completion, the BIM data is also updated each time.

[0036] BIM data also includes information about the disaster prevention equipment installed inside the facility, specifically the product number, manufacturer, price, shape, dimensions, installation location, etc. Furthermore, if the shape of the disaster prevention equipment changes due to use or malfunction, the BIM data also includes information about the shape of the disaster prevention equipment before and after the change.

[0037] Drawing tools are also available that create and draw three-dimensional diagrams of structures from such BIM data. System developers use these drawing tools to create three-dimensional images 30 derived from the BIM data.

[0038] Here, a method for creating a three-dimensional image 30 derived from BIM data in the first embodiment will be described.

[0039] First, the system developer prepares BIM data for the facility for which the system is to be created. This facility is the actual facility that will be the target of disaster prevention measures.

[0040] The system developer first sets a viewpoint that serves as a reference position when creating the three-dimensional image 30. This viewpoint is, for example, the position of each of the icons 251 to 257 shown in FIG.

[0041] The system developer then captures a three-dimensional image of the building's interior one by one while rotating the line of sight 360 degrees around the viewpoint position, thereby creating still images of the interior of the building as seen from each direction, with the viewpoint as the reference position.

[0042] The system developer stores the still images viewed in each direction in the storage unit 23 in association with the corresponding icons 251 to 257.

[0043] If disaster prevention equipment is installed inside the target facility, the BIM data also contains numerical data about the equipment, allowing system developers to include in still images disaster prevention equipment that matches the actual installation location, shape, dimensions, and status before and after activation.

[0044] FIG. 5 is an enlarged view showing the three-dimensional image 301 and the direction indicator bar 401 shown in FIG.

[0045] The direction indicator bar 401 is an object that indicates, with a thick line, the direction in which the currently displayed three-dimensional image 30 is viewed. The direction indicator bar 401 is provided so as to be rotatable, and when the direction indicator bar 401 is rotated, the three-dimensional image 30 is displayed in the viewing direction corresponding to this rotation.

[0046] The examples of FIGS. 4 and 5 illustrate the state of the room 221 when viewed from the position of the icon 253 in a downward direction on the paper.

[0047] Furthermore, because the three-dimensional image 301 is an image derived from BIM data, it is an image that virtually simulates the situation that can be seen at the actual site, including the disaster prevention equipment, as shown in Figure 5. Therefore, by viewing the three-dimensional image 301, disaster prevention center personnel can understand that two smoke detectors S1 have been installed as disaster prevention equipment when they look downward on the page from the position of the icon 253 in the room 221.

[0048] Fig. 6 shows the display screen when the direction indicator bar 401 is operated to point in the opposite direction from the state shown in Fig. 4. Fig. 7 is an enlarged view showing the three-dimensional image 30 and the direction indicator bar 401 shown in Fig. 6.

[0049] 6 and 7, the direction indicator bar 401 is operated so as to be oriented 180° in the opposite direction from the state shown in Figures 4 and 5. Therefore, the three-dimensional image 302 displayed on the display unit 20 is a three-dimensional image of the room 221 when viewed from the position of the icon 253 in the upward direction on the paper.

[0050] By visually viewing the three-dimensional image 302, disaster prevention center personnel can understand that, when they look upward on the paper from the position of the icon 253 in the room 221, in addition to the above, two smoke detectors S1 and one smoke exhaust vent S2 have also been installed as disaster prevention equipment.

[0051] For example, if a fire breaks out in room 221, disaster prevention center personnel can understand the locations and number of disaster prevention equipment in the vicinity of the fire from three-dimensional images 301 and 302, as shown in Figures 4 to 7. In this way, disaster prevention center personnel can visually understand information about disaster prevention equipment in the facility through display unit 20 of display system 2.

[0052] Fig. 8 is a flowchart showing an example of the operation of the display system 2 shown in Fig. 2. It should be noted that the flowchart in Fig. 8 is executed repeatedly.

[0053] In step S101, control unit 25 of display system 2 determines whether or not one of icons 250 arranged on planar map 220 has been selected. If one icon 250 has been selected, control unit 25 advances the process to step S102.

[0054] On the other hand, if none of the arranged icons 250 is selected, the control unit 25 ends the processing of the flowchart in Fig. 8. Note that, since the flowchart in Fig. 8 is executed repeatedly, the determination processing of step S101 is repeated until an icon 250 is selected.

[0055] In step S102, the control unit 25 causes the display unit 20 to display the three-dimensional image 30 corresponding to the selected icon 250.

[0056] In step S103, the control unit 25 determines whether or not the direction indicator bar 401 has been operated. If the direction indicator bar 401 has not been operated, the control unit 25 proceeds to step S105. On the other hand, if the direction indicator bar 401 has been operated, the control unit 25 proceeds to step S104.

[0057] In step S104, the control unit 25 acquires from the storage unit 23 the three-dimensional image 30 corresponding to the viewing direction indicated by the direction indicator bar 401, and causes the display unit 20 to display it.

[0058] In step S105, the control unit 25 determines whether or not a predetermined ending operation has been performed. If the predetermined ending operation has been performed, the control unit 25 ends the processing of the flowchart in Fig. 8. In this case, since the flowchart in Fig. 8 is repeatedly executed, the control unit 25 executes the determination processing of step S101 again.

[0059] If the predetermined ending operation is not performed in step S105, the control unit 25 returns the process to step S103. That is, the process of determining whether the direction indication bar 401 has been operated is repeatedly performed until the predetermined ending operation is performed.

[0060] In the first embodiment, the three-dimensional image 30 is created in advance from the BIM data, and the created three-dimensional image 30 is stored in the storage unit 23 of the display system 2. However, the storage unit 23 of the display system 2 may store the BIM data itself, or the BIM data may be downloaded from a specific site and used as is. In this case, the control unit 25 creates a three-dimensional image each time the specified image is created by operating the icon 250 and the direction indicator bar 401.

[0061] In such an implementation, the above-mentioned drawing tool that generates three-dimensional images from BIM data must be incorporated into the display system 2.

[0062] Furthermore, by storing the BIM data itself in the storage unit 23 or by downloading and using the BIM data as is, the control unit 25 can generate a three-dimensional image that allows visual identification of the operating state or failure state of the disaster prevention equipment and display it on the display unit 20. Furthermore, the control unit 25 can repeatedly generate and display the state of the disaster prevention equipment before and after operation and the state before and after failure each time it receives a predetermined operation from disaster prevention center personnel.

[0063] This allows the display system 2 to display the states of each disaster prevention equipment before and after activation and before and after failure in a manner that allows comparison.

[0064] Incidentally, even in a mode in which three-dimensional images are created in advance from BIM data and the three-dimensional images are stored, the display system 2 can display the state of each disaster prevention equipment before and after activation and the state before and after failure. That is, in addition to the normal state of each disaster prevention equipment, multiple patterns of three-dimensional images, including an activated state or a failed state, are created in advance and stored in the display system 2. In this way, the display system 2 can display the state of each disaster prevention equipment before and after activation and the state before and after failure based on the generated images.

[0065] In the first embodiment, the three-dimensional image 30 is displayed by operating the icons 251 to 257. However, when a fire occurrence signal is received from a fire detector, the three-dimensional image 30 corresponding to the fire detector may be automatically displayed.

[0066] The above-described display system 2 has the following features and can achieve the following effects.

[0067] The display system 2 is a display system equipped with a display unit 20 that aggregates and displays information necessary for centralized control of a fire monitoring area where multiple disaster prevention equipment is located. The display unit 20 can display a three-dimensional image 30 showing the arrangement of each disaster prevention device within the fire monitoring area.

[0068] Therefore, it is possible to obtain a display system 2 that allows easy visual understanding from a remote location of information about each piece of disaster prevention equipment located within a fire monitoring area.

[0069] Furthermore, the three-dimensional image 30 is derived from BIM data. Therefore, the display system 2 can embed information about disaster prevention facilities in the three-dimensional image 30, allowing for more detailed information to be displayed. Furthermore, if the three-dimensional image 30 is updated periodically or updated three-dimensional images 30 are downloaded each time, it is possible to display information that is closer to the current situation.

[0070] This makes it possible to check the appropriate installation positions of sensors and sprinkler heads using the three-dimensional image 30 when there are additions, renovations, changes to partitions, or changes to the placement or replacement of fixtures, etc.

[0071] Furthermore, when displaying the three-dimensional image 30, the display unit 20 visually indicates whether the disaster prevention equipment included in the three-dimensional image 30 is in an operational state or not, and whether it is in a faulty state or not. In the case of equipment whose state is clearly different between its normal state and when it is in operation, the difference in state may be expressed by an image, but it is not necessarily required to show the difference in actual state.

[0072] For example, by displaying an activated smoke detector S1 in a different color than normal, it is possible to know which smoke detector S1 in the room 211 is activated. Furthermore, by displaying a faulty smoke detector S1 in a different color from the above or by making it flash, it is possible to confirm the location of the faulty smoke detector S1 before going to the site.

[0073] Furthermore, if the position and size of fixtures and other items installed in room 211 are reflected in the BIM data, the condition of room 211 can be displayed in more detail, and replacement work can be planned at the disaster prevention center.

[0074] Therefore, the display system 2 can display the status of each disaster prevention equipment before and after activation and the status before and after a malfunction. Therefore, the display system 2 can be used not only when a fire occurs, but also during inspections and when responding to malfunctions. [Explanation of symbols]
