Summary of the Invention

Problems to be Solved by the Invention

[0005] It should be noted that there are some tags like <x

[0004] , <x , * in the original text which seem to be incorrect or incomplete tags. I have translated them as they are while highlighting the potential issues. If these are actual errors in the original, they may need to be corrected for a more accurate translation and understanding of the text.In recent years, incidents have occurred in facilities where vulnerable individuals gather, such as kindergartens, daycare centers, and child welfare facilities, as well as nursing homes, elderly care facilities, and facilities for people with disabilities. When such incidents occur, it is extremely difficult for a limited number of adults and able-bodied individuals to confront the intruder while simultaneously escaping the vulnerable individuals from the facility.

[0006] On the other hand, conventional fire-fighting systems for crime prevention are connected to the public water supply and receive water from that supply to perform the fire-fighting. Because the water supplied from the public water supply is relatively low pressure and low flow rate, conventional fire-fighting systems for crime prevention may have insufficient water pressure and flow rate in relatively large facilities like the one described above.

[0007] Therefore, the present invention aims to provide a security water discharge system capable of supplying a larger volume and higher pressure of water. [Means for solving the problem]

[0008] Honpatsu Akira A security water discharge system to be installed in a facility equipped with an open-type sprinkler system, comprising a water discharge means and a communication means, wherein the water discharge means is connected to a water source via a water supply means, and the water supply means and the water source are shared with the open-type sprinkler system, the communication means has at least a receiving function and is provided to communicate directly or indirectly with a water discharge signal transmitting device, the security water discharge system is connected to a two-way valve, the water discharge signal transmitting device has a fire alarm transmitting means, the water discharge means starts discharging water at an intruder when the two-way valve is opened when the two-way valve is opened and the fire alarm transmitting means is operated, and water can also be discharged from the open-type sprinkler system to the intruder. 。

[0009] Furthermore, inventionIt is possible to provide the water discharge means for each section of the facility, provide the two-way valve for each water discharge means, and switch the opening of the two-way valve to discharge water from the water discharge means in accordance with the movement of the intruder. [Effects of the Invention]

[0010] The present invention provides a security water discharge system that can supply a larger volume and higher pressure of water because the water source and water supply means connected to the security water discharge system are shared with the fire extinguishing system. [Brief explanation of the drawing]

[0011] [Figure 1] This is a simplified system diagram of the security water discharge system and fire extinguishing system in the first embodiment of the present invention. [Figure 2] This is a simplified system diagram of the crime prevention water discharge system and fire extinguishing system in the second embodiment of the present invention. [Figure 3] This figure shows a modified example of the second embodiment of the present invention. [Figure 4] This figure shows a remote control device according to an embodiment of the present invention, where (a) is a front view of one example and (b) is a perspective view of another example. [Figure 5] This is a schematic diagram showing an example of an evacuation guidance device used in conjunction with embodiments of the present invention. [Modes for carrying out the invention]

[0012] A first embodiment of the present invention will be described with reference to Figures 1 and 4. First, the configuration of the crime prevention water discharge system 1 (hereinafter abbreviated as water discharge system 1) of this embodiment will be described. The water discharge system 1 is installed, for example, in kindergartens, nursery schools, child welfare facilities, nursing care facilities, facilities for the elderly and disabled, and other facilities (hereinafter referred to as "facilities"). (Note that the above are examples of facilities in which the water discharge system 1 is installed, and the facilities in which it is installed are not particularly limited.)

[0013] The water discharge equipment 1 is installed in the facility where the fire extinguishing equipment 2 is provided, and is activatable by a remote control device 3, which is an example of a water discharge signal transmitting device. The water discharge equipment 1 comprises a water discharge means 10 and a communication means 11 (hereinafter referred to as the equipment-side communication means 11 to clarify its distinction from the equipment-side communication means 21 described later). In this embodiment, the water discharge equipment 1 further comprises an intruder identification means 12 and a control panel 13.

[0014] In this embodiment, the fire extinguishing system 2 is a closed-type sprinkler system 2A, equipped with a water source 20 and a water supply means 21 such as a pump, and at its end is a sprinkler pipe 23 equipped with a closed-type sprinkler head 22A as a sprinkler head 22. A vertical pipe 25 is connected to the secondary side of the water supply means 21, and the vertical pipe 25 is connected to the sprinkler pipe 23, maintaining a predetermined pressure (such as the shut-off pressure of the water supply means 21) inside the pipe. Furthermore, a two-way valve 24 (normally closed) is provided on a pipe 14 branched from the vertical pipe 25, and a water discharge system 1 is connected to the secondary side of the two-way valve 24. In other words, the water discharge system 1 and the fire extinguishing system 2 share the water source 20 and the water supply means 21. Note that the water discharge means 10 and the closed-type sprinkler head 22A do not necessarily need to be installed in the same compartment.

[0015] Furthermore, in this embodiment, the fire extinguishing system 2 is configured such that when the closed-type sprinkler head 22A is activated, the water supply means 21 is activated to detect the activation and start discharging water from the closed-type sprinkler head 22A. At this time, a water flow detection device 26 is provided on the secondary side of the branch of the vertical pipe 25 from the pipe 14 to detect that the sprinkler system has been activated and to transmit a water flow detection signal to the control panel 13 (which also serves as a fire alarm receiver), which will be described later. Upon receiving the water flow detection signal from the water flow detection device 26, the control panel 13 sounds a bell (not shown) or the like to alert the surrounding area to a fire alarm.

[0016] In addition, since the flowing water detection device 26 has a check valve structure that opens only when water flows from the water supply means 21 in the direction of the closed sprinkler head 22A, even when the two-way valve 24 is opened to discharge water from the water discharge facility 1, the secondary side pressure of the flowing water detection device 26 maintains the monitoring pressure of the closed sprinkler facility 2A. Note that the form of the closed sprinkler fire extinguishing facility 2A is not limited to dry type, wet type, pre-action type, etc., but the piping connection method and operation control between the water discharge facility 1 and the fire extinguishing facility 2 are carried out according to the form of the fire extinguishing facility 2.

[0017] In this embodiment, the water supply means 21 includes a pressure detection device (not shown) that monitors the pressure in the vertical pipe 25, and starts up when the pressure in the vertical pipe 25 falls below a predetermined value, and supplies water from the water source 20.

[0018] The water discharge means 10 is, for example, an open type water discharge gun, which is provided to discharge water to an intruder and repel the intruder. The water discharge means 10 is connected to the water source 20 via the water supply means 21, and water is supplied from the water source 20 to discharge water. In this embodiment, as will be described later, the water discharge means 10 is movable in order to enable water discharge toward a person determined to be an intruder by the intruder identification means 12, and its angle and direction can be freely changed, and it is attached at an appropriate position such as the ceiling, floor, or wall of the facility.

[0019] In addition, in this embodiment, the water discharge means 10 can be used for initial fire extinguishing. As will be described later, when a fire signal is transmitted from the remote operation device 3, the water discharge means 10 can discharge water in the direction where a fire source detection means described later detects a flame such as a small fire.

[0020] The two-way valve 24 is connected to the control panel 13, and when it receives an open signal based on a water discharge signal from the remote operation device 3 from the control panel 13, it communicates the primary side with the pipe 14. In this embodiment, when the control panel 13 receives an open signal based on a fire signal from the remote operation device 3 described later, it also communicates the primary side with the pipe 14.

[0021] The equipment-side communication means 11 has at least a receiving function and is configured to communicate directly or indirectly with the water discharge signal transmitting device. In this embodiment, the equipment-side communication means 11 is installed in various locations within the facility and is configured to communicate directly with the remote control device 3 via wireless communication. Furthermore, the equipment-side communication means 11 is connected to the control panel 13, and the control panel 13 is configured to receive the water discharge signal and / or fire signal described below from the remote control device 3 via the equipment-side communication means 11.

[0022] The control panel 13 is provided to control the water discharge equipment 1, and when it receives the water discharge signal described below from the remote control device 3 via the communication means 11, it transmits an activation signal to the water supply means 21 and an opening signal based on the water discharge signal to the two-way valve 24. In this embodiment, when the control panel 13 receives the fire signal described below from the remote control device 3, it transmits an activation signal to the water supply means 21 and an opening signal based on the fire signal to the two-way valve 24.

[0023] Furthermore, in this embodiment, the control panel 13 also serves as a fire alarm receiver for the fire alarm system and is connected to a sprinkler system including the fire extinguishing system 2, a fire alarm system (not shown), and an emergency broadcasting system 4. When it receives a fire signal, a water flow detection signal, or a water discharge signal, it sends an alarm signal to the emergency broadcasting system 4, which notifies the facility that a fire or incident has occurred inside and / or outside the facility.

[0024] The intruder identification means 12 is equipped with artificial intelligence and is provided to identify intruders who have entered the facility. In this embodiment, the intruder identification means 12 is provided as a facial recognition device and compares the faces of people captured by surveillance cameras 15 installed in various locations of the facility with the faces of facility staff, residents, and legitimate guests that have been registered in advance, and determines that any person who does not match is an intruder. It should be noted that existing surveillance cameras 15 in the facility can also be used.

[0025] Furthermore, the intruder identification means 12 is not limited to a facial recognition device, but can be selected as appropriate. It may also identify weapons such as knives and recognize anyone possessing such weapons as an intruder, or it may be possible to have facility staff, residents, or legitimate guests wear devices that transmit identifiers, and identify anyone not wearing such devices as an intruder. Alternatively, the artificial intelligence may analyze the actions of each person within the facility and identify anyone whose actions are deemed suspicious by the artificial intelligence as an intruder.

[0026] Furthermore, in this embodiment, the intruder identification means 12 is configured to also function as a fire source detection means. Specifically, when a fire signal is transmitted from the remote control device 3, the artificial intelligence analyzes the image displayed on the surveillance camera 15 to detect flames that are not large enough to activate the closed-type sprinkler head 22A, thus also functioning as a flame detection means. It is also possible to provide a fire source detection means separately from the intruder identification means 12.

[0027] The aforementioned water discharge signal transmitting device is provided to transmit a water discharge signal to the equipment-side communication means 11, and in this embodiment, the remote control device 3 plays this role. The remote control device 3 is portable and comprises a portable main unit 30 and transmitting means and communication means 31 (hereinafter referred to as equipment-side communication means 31 to clearly distinguish it from the equipment-side communication means 11) provided on the main unit 30.

[0028] Furthermore, in this embodiment, the remote control device 3 includes a fire alarm alarm 32 and a security alarm 33 as its transmission means. The remote control device 3 also includes a gas detection means (not shown).

[0029] The main body 30 also serves as the exterior of the remote control device 3. In this embodiment, a light-emitting means usable as an emergency light or the like is provided at one end or on one side of the main body. This light-emitting means is provided, for example, as an LED light 34. By making the shape of the light from the LED light 34 a star or other shape that attracts the attention of young children, it becomes possible to make it easier to guide young children to safety in the event of an incident such as a fire.

[0030] Furthermore, the main body 30 is provided with a hole 35 through which a carabiner, chain, or string can be attached to facilitate carrying the remote control device 3. The shape of the main body 30 can be selected as appropriate, but for example, a smartphone type (30A) or a stick type (30B) that is easy to hold in the hand can be selected.

[0031] The equipment-side communication means 31 has at least a transmission function and is provided to communicate directly or indirectly with the equipment-side communication means 11 of the water discharge equipment 1 via wireless communication. The wireless communication standard can be appropriately selected as long as stable communication is possible, and wireless LAN, Bluetooth®, various mobile communication systems, optical wireless communication, and others can be used.

[0032] The fire alarm signaling means 32 is provided so that when the fire alarm signaling means 32 is operated, the water discharge equipment 1 can be used for firefighting purposes via the equipment-side communication means 31. At this time, the water discharge means 10 of the water discharge equipment 1 discharges water to the fire source detected by the fire source detection means, which is also part of the intruder identification device 12. In this embodiment, the fire alarm signaling means 32 is provided as a remote fire extinguishing button located on the main body 30.

[0033] The security transmission means 33 is configured to transmit a water discharge signal to the water discharge equipment 1 via the equipment-side communication means 31 when the security transmission means 33 is operated. In this embodiment, the security transmission means 33 is provided as a security buzzer located in the main unit 30.

[0034] Furthermore, the security transmission means 33 can also be equipped with a locking mechanism 36. For example, in facilities with young children, it is expected that teachers and childcare workers who have frequent direct contact with the children will wear the remote control device 3. The locking mechanism 36 acts as a child lock, preventing young children from tampering with the remote control device 3 and causing it to malfunction.

[0035] Furthermore, the shape of the transmission means can be selected as appropriate, for example, from a button type, slide type, pull cord type, etc. In this embodiment, the fire transmission means 32 is a button type, and the crime prevention transmission means 33 is a button type (33A) or slide type (33B).

[0036] The gas detection means is a sensor that detects gases generated by fire, such as carbon monoxide or carbon dioxide, and preferably has directionality. In this embodiment, the light-emitting means is linked to the gas detection means, and when the gas detection means detects the gas, or when the remote control device 3 is pointed in the direction from which the gas was detected, the color and pattern of the light emitted by the light-emitting means changes to indicate that the concentration of the gas ahead is increasing. It is also possible to provide differences in the color and pattern of the light emitted by the light-emitting means depending on the concentration of the gas.

[0037] Next, the operation process of the water discharge equipment 1 of this embodiment will be described. (1) When the locking means 36 is released and the security transmitting means 33 of the remote control device 3 is operated, the water discharge signal is transmitted to the equipment-side communication means 11 via the device-side communication means 31.

[0038] (2) The water discharge signal is then transmitted from the equipment-side communication means 11 to the control panel 13. The control panel 13 then transmits an open signal to the two-way valve 24 corresponding to the location of the intruder identified by the intruder identification means 12.

[0039] (3) As a result, the water source 20 and the water discharge means 10 are connected, and the pressure in the vertical pipe 25 decreases. When the pressure in the vertical pipe 25 falls below the set value of the pressure detection device of the water supply means 21, the water discharge means 21 is activated. In parallel with this, the intruder identification means 12 directs the water discharge means 10 towards the identified intruder and begins to discharge water.

[0040] Therefore, in the water discharge equipment 1 of this embodiment, the water source 20 and the water supply means 21 are shared with the fire extinguishing equipment 2, making it possible to supply the large-capacity and high-pressure water of the fire extinguishing equipment 2 to the water discharge equipment 1.

[0041] Furthermore, the following are secondary effects of this embodiment. (i) Since the intruder identification means 12 is provided, it is possible to target the intruder with the water discharge means 10, thereby increasing the effectiveness of the water discharge equipment 1 in repelling the intruder.

[0042] (ii) Conventional fire-spraying systems for crime prevention are intended for use when the facility is unoccupied or at night when it is quiet, and they spray water when a suspicious person is detected by a sensor. However, they are not effective for crime prevention during the daytime when the facility is active. With the fire-spraying system 1 of this embodiment, the fire-spraying system 1 can be activated by the remote control device 3, so it can be used for crime prevention during such times.

[0043] (iii) For example, if gasoline or the like is spilled, water can be sprayed at the intruder to wet the source of the fire, such as a lighter, thus preventing arson. Furthermore, as in this embodiment, by branching the closed sprinkler head 22A side and the water discharge means 10 side, water can be discharged simultaneously from both the closed sprinkler head 22A and the water discharge means 10, so even if a fire occurs, a quick response is possible.

[0044] A second embodiment of the present invention will be described with reference to Figures 2 and 4. The difference between this embodiment and the first embodiment is that the fire extinguishing system 2 is an open-type sprinkler system 2B. The components indicated by the same reference numerals as in the first embodiment are the same as in that embodiment, so their description will be omitted.

[0045] In this embodiment, the fire extinguishing system 2 is provided as an open-type sprinkler system 2B, and the open-type sprinkler system 2B is provided in a manner that can be controlled by a remote control device 3.

[0046] In the sprinkler piping 23, an open-type sprinkler head 22B is provided as the sprinkler head 22, instead of the closed-type sprinkler head 22A. In addition, a three-way valve 27 is provided at the branching point of the vertical pipe 25 and pipe 14. Under normal circumstances, it connects the water supply means 21 to the fire extinguishing equipment 2, and is configured to switch to connect the water supply means 21 to pipe 14 when water is being discharged from the water discharge means 10.

[0047] In this embodiment, the control panel 13 is configured to transmit a start signal to the water supply means 21, and the water supply means 21 is activated upon receiving the start signal.

[0048] The operation process of the water discharge equipment 1 in this embodiment is as follows: (1) When the locking means 36 is released and the security transmitting means 33 of the remote control device 3 is operated, a water discharge signal is transmitted via the device-side communication means 31.

[0049] (2) When the equipment-side communication means 11 receives the water discharge signal, the control panel 13 switches the three-way valve 27 to the piping 14 side and sends an activation signal to the water supply means 21, and the transmitting means 21 transmits water from the water source 20.

[0050] (3) The water discharge means 10 discharges water at the intruder according to the intruder identification means 12.

[0051] Furthermore, the operation process of the open-type sprinkler system 2B of this embodiment is as follows. (1) When the fire alarm transmission means 32 of the remote control device 3 is operated, a fire signal is transmitted via the device-side communication means 31.

[0052] (2) When the equipment-side communication means 11 receives the fire signal, the control panel 13 sets the three-way valve 27 to the fire extinguishing equipment side (no switching required under normal operation), sends an activation signal to the water supply means 21, and the transmitting means 21 sends water from the water source 20, which is then discharged from the open sprinkler heads 22B of the open sprinkler system 2B.

[0053] Therefore, the same effects as in the first embodiment can be achieved in this embodiment as well. Furthermore, for example, by setting the system to start water discharge from the fire extinguishing equipment when the fire signal from the remote control device 3 is matched with the fire detection signal from the fire detector in the same area, even if the fire transmission means of the remote control device 3 is accidentally operated, water discharge during non-fire situations can be prevented if the fire detector is not activated.

[0054] Although the present invention has been described based on the above embodiments, the present invention is not limited to the above embodiments and can be modified as appropriate without changing the essence of the invention.

[0055] (A) In the above embodiment, the receiver of the fire alarm system (not shown) is used in conjunction with the control panel 13 of the water discharge system 1, but it is also possible to provide the control panel 13 independently.

[0056] (B) The remote control device 3 may be installed as a fixed facility rather than being portable. In this case, it may be able to communicate with the facility-side communication means 11 via a wired connection instead of wirelessly. Also, if it is a fixed facility, one or more units may be installed in each section or room.

[0057] (C) In the above embodiment, the water discharge means 10 is provided as a water cannon, but the water discharge means 10 is not limited to a water cannon and can be selected as appropriate. For example, multiple fixed nozzles may be provided in each room, or an open-type sprinkler may be installed on the ceiling.

[0058] (D) By providing a two-way valve 24 for each water discharge means 10 provided for each section such as a room or corridor, when the intruder moves, it is possible to switch which two-way valve 24 is opened, thereby discharging water from the most suitable water discharge means 10.

[0059] (E) The transmission means of the remote control device 3 can be linked to broadcasting equipment (not shown) or communication equipment (not shown) installed in the facility, and when the transmission means is operated, the broadcasting equipment or communication equipment can be activated to notify the surrounding area of ​​the facility that an abnormality has occurred at the facility, or to automatically notify agencies such as the police or fire department.

[0060] (F) The remote control device 3 may also be provided with a means to cancel the transmission means (not shown). In this case, the cancellation means may be linked with the emergency broadcasting equipment 4 or the broadcasting equipment and communication equipment of the facility to notify that it was a false alarm or that the incident has been resolved.

[0061] (G) In the second embodiment described above, instead of providing the three-way valve 27, a two-way valve 24 similar to that in the first embodiment and a two-way valve 28 provided on the vertical piping 25 side after the branch of the vertical piping 25 from the piping 14 may be provided (see Figure 3). In this case, the control will be such that the two-way valves 24 and 28 that communicate with the equipment to discharge water are selected and opened.

[0062] In this way, the system is set to start water discharge from the fire extinguishing equipment when the fire signal from the remote control device 3 and the fire detection signal from the fire detector in the same section are matched. Furthermore, if the fire alarm signaling device of the remote control device 3 is operated with the two-way valve 24 open for an intruder, water can be discharged from the fire extinguishing equipment even if the fire detector is not activated. This allows the water to be used to target the intruder while also being discharged from the entire room, further intimidating the intruder.

[0063] (H) In the above embodiment, initial fire suppression is possible by the water discharge means 10, but it is also possible to dedicate the water discharge means 10 solely to spraying water on intruders.

[0064] (I) In the above embodiment, the water discharge equipment 1 is activated manually, but it is also possible to activate it automatically. In this case, the water discharge signal transmitting device can be linked to, for example, the intruder identification means 12, so that when the artificial intelligence identifies an intruder, the water discharge means 10 automatically discharges water.

[0065] (J) The transmission means of the remote control device 3 can be linked to the evacuation guidance device 5 (see Figure 5), so that when the transmission means is operated, the evacuation guidance device 5 is activated. The communication between the remote control device 3 and the evacuation guidance device 5 can be the same as the communication between the remote control device 3 and the security water discharge equipment 1.

[0066] The evacuation guidance device 5 is installed in the evacuation area R and has an acoustic means 50 and / or an image display means 51. The acoustic means 50 plays entertainment sounds, such as music or sounds that can attract the attention of infants, to guide them to the evacuation area R, and the image display means 51 displays images that can attract the attention of infants, to keep them at the evacuation area.
