[0011] Hereinafter, a method for proposing installation and an installation proposal system of a fire omen detection system according to an embodiment will be described in detail with reference to the drawings. However, each of the drawings described in the following embodiments is a schematic diagram, and the respective ratios of the sizes and thicknesses of the respective components do not necessarily reflect the actual dimensional ratios. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications can be made according to the design and the like as long as the effects of the present disclosure can be achieved.

[0012] (Embodiment) (1) Outline The installation proposal system 1 (see FIG. 1) is a system for proposing the arrangement of the sensors 3 of the fire omen detection system 100 (see FIG. 2).

[0013] Here, the fire omen detection system 100 is a system for detecting a fire in a space to be monitored 10 (see FIGS. 4 and 5) and a fire omen in the space to be monitored 10. The space to be monitored 10 corresponds to the space of the present disclosure. Here, the fire omen refers to a state that has not reached a state called a fire, such as an overheating phenomenon by tracking, but has a high possibility of developing into a fire.

[0014] The space to be monitored 10 is, for example, a space partitioned as one section in an office, a store, an office, a factory, a warehouse, a building, a school, a welfare facility, a hospital, or the like.

[0015] (2) Configuration (2.1) Configuration of Fire Omen Detection System Prior to the description of the installation proposal system 1, the configuration of the fire omen detection system 100 will be described.

[0016] As shown in FIG. 2, the fire omen detection system 100 includes a management server 2 and a plurality (two in FIG. 1) of sensors 3.

[0017] Each of the plurality of sensors 3 detects a fire and a fire omen in the monitored space 10. More specifically, the sensor 3 detects heat or smoke caused by a fire in the monitored space 10. Further, the sensor 3 detects smoke or gas caused by a fire omen in the monitored space 10.

[0018] Each of the plurality of sensors 3 includes, for example, a detection unit 31 and a communication unit 32.

[0019] The detection unit 31 is, for example, an optical smoke sensor. Further, the detection unit 31 is, for example, a heat sensor. Further, the detection unit 31 may be, for example, a gas sensor.

[0020] The communication unit 32 transmits the detection result of the detection unit 31 to the management server 2 via the network NT1. For example, when the detection unit 31 detects a fire, the communication unit 32 transmits a signal indicating the fire detection. The communication unit 32 has an interface for connecting to the network NT1 and has, for example, a wireless interface corresponding to Bluetooth, Bluetooth LE, etc. Further, the communication unit 32 may have, for example, a wired interface corresponding to Ethernet or the like.

[0021] Further, the plurality of sensors 3 may further include, for example, a notification unit. For example, when the detection unit 31 detects a fire, the notification unit performs notification using sound, light, or both sound and light.

[0022] The management server 2 receives information from each of the plurality of sensors 3 and detects a fire in the monitored space 10. When the management server 2 receives a signal based on fire omen detection or fire detection from any one of the plurality of sensors 3, it notifies that a fire omen has been detected or a fire has occurred in the monitored space 10.

[0023] The management server 2 includes, for example, a determination unit 21 and a communication unit 22.

[0024] Based on the detection results from the plurality of sensors 3, the determination unit 21 determines whether there is a fire omen and whether a fire has occurred in the monitoring target space 10. For example, when the determination unit 21 is notified of the detection of a fire omen from any one of the plurality of sensors 3, it determines that a fire omen has occurred in the monitoring target space 10. Also, for example, when the determination unit 21 is notified of the detection of a fire from any one of the plurality of sensors 3, it determines that a fire has occurred in the monitoring target space 10.

[0025] The communication unit 22 receives a signal indicating that a fire omen or a fire has been detected from the plurality of sensors 3 via the network NT1. The communication unit 22 has an interface for connecting to the network NT1, and for example, has a wireless interface corresponding to Bluetooth, Bluetooth LE, etc. Also, the communication unit 22 may have a wired interface corresponding to, for example, Ethernet.

[0026] Note that the management server 2 may have a notification unit. When the determination unit 21 determines that a fire omen or a fire has occurred in the monitoring target space 10, the notification unit performs notification using sound, light, or both sound and light. The notification unit changes the notification mode, for example, when a fire omen occurs in the monitoring target space 10 and when a fire occurs in the monitoring target space 10. Note that the notification unit may cause an information terminal or the like to perform notification indicating that a fire omen or a fire has occurred in the monitoring target space 10 via the communication unit 22.

[0027] The management server 2 includes a computer system. Note that the management server 2 may be, for example, a fire receiver.

[0028] (2.2) Configuration of the Installation Proposal System As shown in FIG. 1, the installation proposal system 1 includes an information acquisition unit 11, an air flow prediction unit 12, and a sensor placement proposal unit 13.

[0029] The information acquisition unit 11 acquires information on the monitoring target space 10 that is necessary for the simulation of the airflow within the monitoring target space 10.

[0030] The information on the monitoring target space 10 includes, for example, the shape or layout of the monitoring target space 10. Also, the information on the monitoring target space 10 may include either the shape or the layout of the monitoring target space 10. Thereby, it becomes possible to more accurately predict the airflow in the monitoring target space 10.

[0031] Further, the information on the monitoring target space 10 includes, for example, information regarding the air inlets and outlets of the monitoring target space 10. The information on the monitoring target space 10 includes, for example, information on the air intake of the air conditioner, the air exhaust of the air conditioner, and the ventilation openings. Thereby, it becomes possible to predict the airflow in the monitoring target space 10 taking into account the influence of the airflow entering and leaving the monitoring target space 10.

[0032] The airflow prediction unit 12 predicts the airflow in the monitoring target space 10 based on the information on the monitoring target space 10 acquired by the information acquisition unit 11. More specifically, the airflow prediction unit 12 predicts the airflow in the monitoring target space 10 using computer simulation. The simulation is performed, for example, using the structural grid-based general-purpose three-dimensional thermal fluid analysis system STREAM (manufactured by Software Cradle Co., Ltd.).

[0033] The sensor placement proposal unit 13 proposes the placement of the sensor 3 for detecting a fire based on the airflow in the monitoring target space 10 predicted by the airflow prediction unit 12. The sensor placement proposal unit 13 proposes placing the sensor 3 at a position along the flow of the airflow in the monitoring target space 10 based on the airflow in the monitoring target space 10. The sensor placement proposal unit 13 proposes, for example, installing the sensor 3 at a position near the wall surface or the ceiling surface in the monitoring target space 10 and where the airflow is flowing without diffusion.

[0034] The sensor placement proposal unit 13 has, for example, a display unit and displays on the display unit an image obtained by mapping positions in the monitoring target space 10 that are candidates for the position of the sensor 3. Further, the sensor placement proposal unit 13 outputs, for example, information indicating positions in the monitoring target space 10 that are candidates for the position of the sensor 3. The information indicating positions that are candidates for the position of the sensor 3 is, for example, three-dimensional coordinates with a position within the monitoring target space 10 as the origin.

[0035] The setting proposal system 1 includes a computer system. The computer system mainly consists of a processor and a memory as hardware. By the processor executing a program recorded in the memory of the computer system, the function as the management server 2 in the present disclosure is realized. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunication line, or may be provided by being recorded on a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive readable by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). Here, integrated circuits such as the IC or LSI mentioned here have different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, for an FPGA (Field-Programmable Gate Array) programmed after the manufacture of the LSI, or a logic device capable of reconfiguring the bonding relationship inside the LSI or reconfiguring the circuit section inside the LSI, it can also be adopted as a processor. The one or more electronic circuits may be integrated on one chip, or may be provided dispersedly on a plurality of chips. The plurality of chips may be integrated in one device, or may be provided dispersedly in a plurality of devices. The computer system mentioned here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0036] Moreover, it is not an essential configuration for the installation proposal system 1 that a plurality of functions in the installation proposal system 1 are integrated in one housing, and the components of the installation proposal system 1 may be provided in a distributed manner in a plurality of housings. Further, at least some functions of the installation proposal system 1, for example, some functions of the airflow prediction unit 12 may be realized by a cloud (cloud computing) or the like.

[0037] Conversely, in the embodiment, at least some functions of the installation proposal system 1 that are distributed among a plurality of components may be integrated in one housing.

[0038] (3) Operation FIG. 3 is a flowchart showing the operation of the installation proposal system 1 according to the embodiment.

[0039] The information acquisition unit 11 of the installation proposal system 1 acquires information on the monitoring target space 10 (information acquisition step S1).

[0040] The information on the monitoring target space 10 includes, for example, the shape or layout of the monitoring target space 10. Also, the information on the monitoring target space 10 includes, for example, both the shape and layout of the monitoring target space 10. For example, the information on the monitoring target space 10 shown in FIG. 4 includes information indicating that the shape of the monitoring target space 10 is a rectangular parallelepiped and the lengths of each of the three sides. Also, the information on the monitoring target space 10 shown in FIG. 4 includes, for example, the position and size of a desk, which is furniture, as the layout of the monitoring target space 10. Also, for example, the information on the monitoring target space 10 shown in FIG. 5 includes, for example, the planar shape and size of the room and the height as the shape of the monitoring target space 10. Also, the information on the monitoring target space 10 shown in FIG. 5 includes, for example, the positions and sizes of a desk and a chair, which are furniture, as the layout of the monitoring target space 10.

[0041] In addition, the information on the monitored space 10 includes, for example, information regarding the air inlets and outlets of the monitored space 10. The information on the monitored space 10 includes, for example, information on the air intake of the air conditioner, the air exhaust of the air conditioner, and the ventilation openings. For example, the information on the monitored space 10 shown in FIG. 4 includes information on the air supply and exhaust openings 41 and the air intake 42 of the air conditioner. Further, for example, the information on the monitored space 10 shown in FIG. 5 includes information on the blow-through structure 43 that serves as a ventilation hole. In addition, the information regarding the air inlets and outlets of the monitored space 10 is not limited to the above examples, and any information related to openings such as windows and doors where air flow can occur is acceptable.

[0042] Next, the air flow prediction unit 12 of the installation proposal system 1 predicts the air flow in the monitored space 10 based on the information on the monitored space 10 acquired by the information acquisition unit 11 (air flow prediction step S2). More specifically, the air flow prediction unit 12 predicts the air flow in the monitored space 10 by computer simulation based on the information on the monitored space 10. In FIG. 4, the air flow in the plane 101 of the monitored space 10 is indicated by arrows. In the monitored space 10 shown in FIG. 4, a fast air flow occurs in the region 111 near the air supply and exhaust openings 41 of the air conditioner, and an even faster air flow occurs in the two adjacent regions 112. Also, in the monitored space 10 shown in FIG. 4, a region with a fast air flow also occurs in the region 113 away from the air intake 42. In FIG. 5, the air flow in the ceiling portion of the monitored space 10 is indicated by arrows. In the monitored space 10 shown in FIG. 5, an air flow toward the blow-through structure 43 and an air flow entering from the blow-through structure 43 occur.

[0043] Next, based on the airflow in the monitoring target space 10 predicted by the airflow prediction unit, the sensor placement proposal unit 13 of the installation proposal system 1 proposes the placement of the sensor 3 for detecting a fire (sensor placement proposal step S3). The sensor placement proposal unit 13 proposes to place the sensor 3 at a position along the flow of the airflow in the monitoring target space 10 based on the airflow in the monitoring target space 10. For example, the sensor placement proposal unit 13 proposes to install the sensor 3 at a position where the airflow concentrates in the monitoring target space 10. For example, in the monitoring target space 10 shown in FIG. 4, it is proposed to install the sensor 3 near the air supply and exhaust ports 41 of the air conditioner, or at a position where the airflow concentrating towards the air supply and exhaust ports 41 or the intake port 42 of the air conditioner. Further, for example, in the monitoring target space 10 shown in FIG. 5, it is proposed to install the sensor 3 within the region 10a where the airflow flowing stably towards the wall and the blow-through structure 43 is located near the wall.

[0044] (4) Effects The installation proposal method of the fire omen detection system 100 according to the embodiment is executed by one or more processors and includes an information acquisition step S1, an airflow prediction step S2, and a sensor placement proposal step S3. In the information acquisition step S1, information on the monitoring target space 10 that is the installation target of the fire omen detection system 100 is acquired. In the airflow prediction step S2, the airflow in the monitoring target space 10 is predicted based on the information on the monitoring target space 10. In the sensor placement proposal step S3, based on the airflow predicted in the airflow prediction step S2, the placement of the sensor 3 for detecting a fire or a fire omen is proposed. Thereby, since it becomes possible to place the sensor 3 at a position where the concentration of smoke, gas, etc. is sufficiently high due to the airflow in the monitoring target space 10, it becomes possible to improve the detection accuracy of the fire omen detection system 100.

[0045] Also, in the installation proposal method of the fire omen detection system 100 according to the embodiment, the airflow prediction step S2 is executed using computer simulation. Thereby, it becomes possible to predict the airflow in the monitoring target space 10 with high accuracy. Therefore, it becomes possible to place the sensor 3 at a more appropriate position.

[0046] In addition, in the method for proposing the installation of the fire omen detection system 100 according to the embodiment, the information on the monitoring target space 10 includes at least one of the shape and layout of the monitoring target space 10. Thereby, it becomes possible to more accurately predict the airflow in the monitoring target space 10.

[0047] In addition, in the method for proposing the installation of the fire omen detection system 100 according to the embodiment, the information on the monitoring target space 10 includes information related to at least one of the intake port, exhaust port of the air conditioner installed in the monitoring target space 10, and the ventilation port installed in the monitoring target space 10. Thereby, by using the inflow and outflow of air into the monitoring target space 10 for prediction, it becomes possible to more accurately predict the airflow in the monitoring target space 10.

[0048] In addition, in the method for proposing the installation of the fire omen detection system 100 according to the embodiment, in the sensor placement proposal step S3, the placement of the sensor 3 is proposed at the position where the airflow predicted by the airflow prediction step S2 converges. Thereby, when gases, smoke, etc. generated by a fire or a fire omen in the monitoring target space 10 reach the sensor 3, the concentration is less likely to decrease. Therefore, the fire omen detection system 100 can detect fire omens and fires with higher accuracy.

The information acquisition unit 11 acquires information on the monitoring target space 10 which is the installation target of the fire omen detection system 100. The airflow prediction unit 12 predicts the airflow in the monitoring target space 10 based on the information on the monitoring target space 10. The sensor placement proposal unit 13 proposes the placement of the sensor 3 for detecting a fire or a fire omen. Thereby, since it becomes possible to place the sensor 3 at a position where the concentration of smoke, gas, etc. is sufficiently high due to the airflow in the monitoring target space 10, it becomes possible to improve the detection accuracy of the fire omen detection system 100.
