Description

[Technical Field]

[0001] The present disclosure relates to a notification transmitting / receiving device, a notification system, a fire extinguisher stand, a notification transmitting device, and a notification receiving device. [Background technology]

[0002] When a fire breaks out in a building, it is important to carry out initial firefighting activities quickly and continuously using multiple fire extinguishers. In particular, in large facilities that contain many combustible materials, such as warehouses and laboratories, such initial firefighting activities have a significant impact on the extent of the damage caused by the fire.

[0003] On the other hand, fire extinguishers are generally stored in fire extinguisher stands as disclosed in Patent Document 1 and placed at predetermined intervals, but few people know the locations of the fire extinguisher stands.Therefore, as disclosed in Patent Document 2, a disaster prevention display device is known that receives disaster prevention information such as a fire signal and displays a map of the monitored object, such as a building floor plan showing symbols of disaster prevention terminal devices, on the screen of the display device, making it easy to determine the locations of fire extinguishers in the event of a fire.

[0005] If the fire extinguisher is covered in a fire extinguisher stand as in Patent Document 1, it may be difficult to see it in an emergency such as a fire. Also, with a disaster prevention display device as in Patent Document 2, it is necessary to move to the location of the display screen, move from there to the location of the fire extinguisher, and then move to the location of the fire, which may increase the travel distance. As such, the technologies in Patent Documents 1 and 2 have the problem that they do not necessarily lead to rapid and continuous initial firefighting activities.

[0008] In order to achieve the above-mentioned objective, in the alarm system of the present disclosure, the alarm transmission / reception device is attached to each of multiple fire extinguisher stands, and the transmission and reception of the instruction information is performed between the alarm transmission / reception devices.

[0009] In order to achieve the above-mentioned object, the fire extinguisher stand according to the present disclosure is equipped with the above-mentioned alarm transmitting and receiving device.

[0014] 1. First embodiment 1 is a schematic perspective view showing an example of an alarm system 1 according to a first embodiment of the present disclosure. The alarm system 1 includes a plurality of alarm transmission / reception devices 10. The alarm transmission / reception devices 10 are devices attached to fire extinguisher stands 3 for arranging fire extinguishers 5, and are devices for notifying the presence of the fire extinguishers 5 installed in the fire extinguisher stands 3. The alarm transmission / reception devices 10 are attached to each of the plurality of fire extinguisher stands 3 included in the alarm system 1. Furthermore, the alarm transmission / reception devices 10 of this embodiment are independent from the fire extinguisher stands 3, and are so-called retrofit devices that can be freely attached and detached.

[0015] In the notification system 1, one or more other notification transmitting / receiving devices 10 exist within the wireless communication range of each notification transmitting / receiving device 10. The wireless communication range of a notification transmitting / receiving device 10 is specifically a range in which short-distance wireless communication is possible, for example, a range with a radius of about 20 m to 40 m.

[0016] Each notification transmitting / receiving device 10 is capable of wireless communication with other notification transmitting / receiving devices 10 within the wireless communication range using P2P technology, and instruction information corresponding to a notification instruction is transmitted and received between notification transmitting / receiving devices 10. Note that, below, instruction information corresponding to a notification instruction may be simply referred to as "instruction information."

[0017] Furthermore, each notification transmitting / receiving device 10 can detect that a fire extinguisher 5 has been removed from the corresponding fire extinguisher stand 3. Furthermore, when a fire extinguisher 5 is removed from the corresponding fire extinguisher stand 3, each notification transmitting / receiving device 10 transmits instruction information to other notification transmitting / receiving devices 10 within the wireless communication range. The fire extinguisher stand 3 is a structural stand with two side panels connected in an L-shape at a rectangular bottom and erected upright.

[0018] 1, in the alarm system 1, when the first fire extinguisher 5a is removed from the first fire extinguisher stand 3a, the first alarm transmission / reception device 10a transmits instruction information to other alarm transmission / reception devices (the second alarm transmission / reception device 10b and the third alarm transmission / reception device 10c) within the wireless communication range of the first alarm transmission / reception device 10a. Then, the second alarm transmission / reception device 10b and the third alarm transmission / reception device 10c, which have received the instruction information, issue alarms using sound or light, respectively. Furthermore, when the second fire extinguisher 5b is removed from the second fire extinguisher stand 3b or the third fire extinguisher 5c is removed from the third fire extinguisher stand 3c, instruction information is transmitted from there to other alarm transmission / reception devices (not shown) within the wireless communication range of the second alarm transmission / reception device 10b or the third alarm transmission / reception device 10c, thus creating a chain of alarms.

[0019] 2 is a block diagram showing an example of the electrical configuration of the notification transmitting / receiving device 10 of the first embodiment. The notification transmitting / receiving device 10 includes a control unit 12, a detection unit 18, a communication unit 20, a notification unit 26, a power supply circuit 32, a self-power generation unit 34, an energy harvesting unit 36, and a power storage unit 38.

[0020] The control unit 12 is electrically connected to each of the detection unit 18, communication unit 20, notification unit 26, and power supply circuit 32 via a circuit such as a bus. In addition, the power supply circuit 32 is electrically connected to each of the self-power generation unit 34, energy harvesting unit 36, power storage unit 38, and commercial power supply 40 via a circuit such as a bus.

[0021] In the notification transmission / reception device 10, the control unit 12, detection unit 18, communication unit 20, and notification unit 26 belong to a functional system 31, and the power supply circuit 32, self-power generation unit 34, environmental power generation unit 36, and storage unit 38 belong to a power supply system 39.

[0022] The control unit 12 is a computer. The control unit 12 includes a CPU (Central Processing Unit) 14 and a storage unit 16 that can be directly accessed by the CPU 14. The storage unit 16 includes, for example, a volatile memory (volatile storage device) and a nonvolatile memory (nonvolatile storage device).

[0023] The storage unit 16 stores programs and data for implementing various operations and various processes of the notification transmitting / receiving device 10. The storage unit 16 may also store various pieces of information received from the outside as data.

[0024] The detection unit 18 detects the removal of the fire extinguisher 5 from the fire extinguisher stand 3. Specifically, the detection unit 18 is a weight sensor. The detection unit 18 is provided at the location of the fire extinguisher stand 3 where the fire extinguisher 5 is installed, and detects the removal of the fire extinguisher 5 from the fire extinguisher stand 3 by detecting a weight equal to or less than a threshold corresponding to the weight of the fire extinguisher 5. In other words, the detection unit 18 detects that the fire extinguisher 5 has been removed from the fire extinguisher stand 3 when the weight equivalent to the fire extinguisher 5 is no longer detected.

[0025] The threshold value corresponding to the weight of the fire extinguisher 5 is, for example, a weight that is less than the weight of the fire extinguisher 5. Furthermore, if another item is additionally attached to the fire extinguisher 5, the threshold value corresponding to the weight of the fire extinguisher 5 is, for example, a weight that is less than the total weight of the fire extinguisher 5 and the weight of the item attached to the fire extinguisher 5.

[0026] The communication unit 20 performs short-range wireless communication with the outside. Specifically, the communication unit 20 performs short-range wireless communication with another notification transmitting / receiving device 10. The communication unit 20 performs communication in accordance with, for example, the international standard ISO / IEC14543-3-10. Note that the communication method used by the communication unit 20 is not limited to this, and for example, wireless LAN, Bluetooth (registered trademark), infrared, etc. may also be used. The communication unit 20 includes a transmission unit 22 and a reception unit 24.

[0027] The transmitter 22 includes a communication module, a communication circuit for wirelessly transmitting information, or the like. When the fire extinguisher 5 is removed from the fire extinguisher stand 3, the transmitter 22 transmits instruction information to the outside under the control of the control unit 12. Specifically, when the detection unit 18 detects that the fire extinguisher 5 has been removed from the fire extinguisher stand 3, the transmitter 22 transmits instruction information to the outside under the control of the control unit 12.

[0028] The receiving unit 24 includes a communication module, a communication circuit for receiving information wirelessly, or the like, similar to the transmitting unit 22. The receiving unit 24 receives instruction information transmitted from the outside under the control of the control unit 12.

[0029] The notification unit 26 notifies the presence of the fire extinguisher 5 installed in the fire extinguisher stand 3. Specifically, the notification unit 26 visually and audibly notifies people in the vicinity of the presence of the fire extinguisher 5. To this end, the notification unit 26 includes a light-emitting unit 28 and a sound-emitting unit 30.

[0030] The light-emitting unit 28 uses light to alert the user to the presence of the fire extinguisher 5. The light-emitting unit 28 is, for example, a general-purpose light source such as an LED (Light Emitting Diode) lamp. From the viewpoint of visibility, the light-emitting unit 28 may be controlled to flash, for example. Furthermore, if the light-emitting unit 28 is equipped with multiple light sources, the light sources may be controlled to turn on and off in sequence, tracing a specific trajectory or character. Furthermore, the color of the light emitted by the light-emitting unit 28 is preferably a color (e.g., red or yellow) that can be distinguished from the surrounding light and indicates an emergency.

[0031] The sound output unit 30 outputs a sound to alert the user to the presence of the fire extinguisher 5. The sound output unit 30 is, for example, a general-purpose buzzer, a general-purpose speaker, or an electrically controllable bell. The sound output may be a buzzer sound or a voice announcement such as "There is a fire extinguisher" or "There is a fire."

[0032] When the receiving unit 24 receives instruction information transmitted from the outside, the alarm unit 26, under the control of the control unit 12, alerts the presence of the fire extinguisher 5. Specifically, when the receiving unit 24 receives instruction information transmitted from the outside, the alarm unit 26 alerts the presence of the fire extinguisher 5 until the fire extinguisher 5 is removed from the fire extinguisher stand 3. In other words, when the receiving unit 24 receives instruction information transmitted from the outside, the alarm unit 26 alerts the presence of the fire extinguisher 5 until the detection unit 18 detects that the fire extinguisher 5 has been removed from the fire extinguisher stand 3.

[0033] The notification transmitting / receiving device 10 triggers the start of notification when instruction information is received, and triggers the end of notification when the corresponding fire extinguisher 5 is removed. Note that the end of notification is not limited to this, and may be limited to a predetermined time, or may be possible to manually terminate the notification by providing an operating unit such as a button.

[0034] For these reasons, in the notification transmission / reception device 10, the control unit 12 and the transmission unit 22 correspond to a function of transmitting instruction information to the outside and linking with the outside (external linking function), and the control unit 12, the receiving unit 24, and the notification unit 26 correspond to a function of issuing a notification when instruction information transmitted from the outside is received (notification function).

[0035] The power supply circuit 32 receives power from at least one of the self-power generation unit 34, the environmental power generation unit 36, the power storage unit 38, and the commercial power source 40, and converts the power as appropriate to supply power to each component of the functional system 31 as appropriate.

[0036] The self-power generating unit 34 is a component that converts specific movements such as switching into electrical energy, and generates electricity from the movement (movement, displacement) of the fire extinguisher 5 when the fire extinguisher 5 is removed from the fire extinguisher stand 3.

[0037] For example, the self-power generating unit 34 is a self-power generating push-button switch that is provided at the bottom of the fire extinguisher stand 3, and when the fire extinguisher 5 is installed, the fire extinguisher 5 is placed on the push-button switch, which is in a pressed state, and when the fire extinguisher 5 is removed, the push-button switch returns to its original position, generating electricity.

[0038] The power generation by the self-power generation unit 34 is usually instantaneous, and the timing at which the power generation by the self-power generation unit 34 occurs can be said to be the timing at which the fire extinguisher 5 is removed from the fire extinguisher stand 3, and it is possible for the self-power generation unit 34 to essentially play the same role as the detection unit 18. On the other hand, the self-power generation unit 34 can also play the role of a power source.

[0039] The self-power generation unit 34 generates power in accordance with, for example, the international standard ISO / IEC 14543-3-10. The self-power generation unit 34 includes, for example, a piezoelectric element or an electromagnetic induction power generation element, and is provided at a location of the fire extinguisher stand 3 that comes into contact with the fire extinguisher 5 or in the vicinity of that location.

[0040] Furthermore, if the fire extinguisher stand 3 includes a member for locking or supporting the fire extinguisher 5, the self-power generating unit 34 is provided on such a member. A specific example of a member for locking or supporting the fire extinguisher 5 is a leaf spring that holds the side of the fire extinguisher 5.

[0041] Since the timing at which the self-power generating unit 34 generates electricity is also the timing at which the fire extinguisher 5 is removed from the fire extinguisher stand 3, it is preferable that the electricity obtained by the power generation by the self-power generating unit 34 be used when transmitting instruction information to the outside.

[0042] Furthermore, when the fire extinguisher 5 is removed from the fire extinguisher stand 3 and power is generated by the self-generating unit 34, power including the power obtained by the power generation by the self-generating unit 34 is supplied to the functional system 31, and the transmitting unit 22 uses the power including the power obtained by the power generation by the self-generating unit 34 to transmit instruction information to the outside.

[0043] The term "electricity including power obtained by power generation by the self-power generation unit 34" means that when there is a power shortage, power supplied from other power sources (environmental power generation unit 36, power storage unit 38, commercial power supply 40) is also used in addition to the power obtained by power generation by the self-power generation unit 34. In other words, the term "electricity including power obtained by power generation by the self-power generation unit 34" also means that when there is sufficient power, only the power obtained by power generation by the self-power generation unit 34 is used.

[0044] The energy harvesting unit 36 ​​generates power from the surrounding environment of the location where the fire extinguisher stand 3 is placed. Therefore, the energy harvesting unit 36 ​​can also serve as a power source. The energy harvesting unit 36 ​​can generate power for a certain period of time or continuously, depending on the surrounding environment.

[0045] In this embodiment, the energy harvesting unit 36 ​​is, for example, a component that converts vibration energy into electrical energy, and generates power from vibrations in the vicinity of where the fire extinguisher stand 3 is located. In this case, the energy harvesting unit 36 ​​is made up of, for example, a piezoelectric element or an electromagnetic induction power generating element, and comes into contact with the floor of the building to receive the vibrations.

[0046] Furthermore, the energy harvesting unit 36 ​​may be, for example, a component that converts light energy into electrical energy and generates power using the ambient light around the location where the fire extinguisher stand 3 is located. In this case, the energy harvesting unit 36 ​​is made up of, for example, a perovskite solar cell or the like.

[0047] Furthermore, the energy harvesting unit 36 ​​may be, for example, a component that converts sound energy into electrical energy and generates power from sounds around the location where the fire extinguisher stand 3 is placed. In this case, the energy harvesting unit 36 ​​may be, for example, a sound power generating element.

[0048] The power obtained by the power generation of the environmental power generation unit 36 ​​is supplied as needed to each component of the functional system 31. The power obtained by the power generation of the environmental power generation unit 36 ​​can also be temporarily stored in the power storage unit 38 and then supplied as needed to each component of the functional system 31.

[0049] The power storage unit 38 is a secondary battery that stores and supplies power as needed, and therefore can also function as a power source.

[0050] The power storage unit 38 is supplied with, for example, at least a portion of the power obtained by power generation by the environmental power generation unit 36 ​​(so-called charging), as appropriate. Also, for example, the power storage unit 38 is supplied with, for example, at least a portion of the power supplied from a commercial power source 40, as appropriate. Furthermore, the power storage unit 38 can be attached to and detached from the notification transmission / reception device 10, and can also be charged externally to store power. Furthermore, the power stored in the power storage unit 38 is supplied to each component of the functional system 31 as appropriate.

[0051] When a fire extinguisher 5 is taken out of a fire extinguisher stand 3, such an alarm transmission / reception device 10 transmits instruction information to another alarm transmission / reception device 10. Furthermore, when the alarm transmission / reception device 10 receives instruction information transmitted from another alarm transmission / reception device 10, it notifies the presence of the fire extinguisher 5. In other words, by cooperating with each other, the alarm transmission / reception devices 10 notify the presence of a fire extinguisher 5 near the fire extinguisher stand 3 from which the fire extinguisher 5 was taken out.

[0052] 3 is a flowchart showing an example of processing by the control unit 12 of the notification transmitting / receiving device 10 of the first embodiment. The flowchart shown in FIG. 3 starts, for example, when the notification transmitting / receiving device 10 is started or when the fire extinguisher 5 is installed in the fire extinguisher stand 3.

[0053] In step S1, the control unit 12 determines whether or not instruction information has been received from the outside. If the determination in step S1 is "NO," that is, if instruction information has not been received from the outside, the control unit 12 proceeds from step S1 to step S6. On the other hand, if the determination in step S1 is "YES," that is, if instruction information has been received from the outside, the control unit 12 proceeds to step S2.

[0054] In step S2, the control unit 12 starts notifying the presence of the fire extinguisher 5 using the notification unit 26. Specifically, the control unit 12 starts notifying the presence of the fire extinguisher 5 using the light-emitting unit 28 and the sound-emitting unit 30. After starting to notify the presence of the fire extinguisher 5 in step S2, the control unit 12 proceeds to step S3.

[0055] In step S3, the control unit 12 determines whether or not it has detected the removal of the fire extinguisher 5. Specifically, the control unit 12 determines whether or not the detection unit 18 has detected the removal of the fire extinguisher 5 from the fire extinguisher stand 3.

[0056] If the determination in step S3 is "NO", that is, if the removal of the fire extinguisher 5 has not been detected, the control unit 12 repeats the determination in step S3. On the other hand, if the determination in step S3 is "YES", that is, if the removal of the fire extinguisher 5 has been detected, the control unit 12 proceeds to the process in step S4.

[0057] In step S4, the control unit 12 ends the notification of the presence of the fire extinguisher 5. Furthermore, when the notification of the presence of the fire extinguisher 5 ends in step S4, the control unit 12 advances the process to step S5.

[0058] In step S5, the control unit 12 transmits the instruction information to the outside. Specifically, the control unit 12 transmits the instruction information to the outside using the transmission unit 22. After transmitting the instruction information to the outside in step S5, the control unit 12 ends the flow shown in Fig. 3. Note that the flow shown in Fig. 3 can be interrupted as necessary.

[0059] On the other hand, if instruction information is received from the outside and the determination in step S1 is "NO", in step S6, the control unit 12 determines whether or not removal of the fire extinguisher 5 has been detected, similarly to step S3.

[0060] If the determination in step S6 is "NO", that is, if the removal of the fire extinguisher 5 has not been detected, the control unit 12 returns the process to step S1. On the other hand, if the determination in step S6 is "YES", that is, if the removal of the fire extinguisher 5 has been detected, the control unit 12 proceeds to the process in step S5 described above, transmits instruction information to the outside, and then ends the flow.

[0061] The flow chart shown in FIG. 3 is an example, and the order of the steps can be changed as desired as long as the same effect can be obtained.

[0062] According to this type of notification transmitting / receiving device 10, when a fire extinguisher 5 is removed from a fire extinguisher stand 3, instruction information is transmitted to other notification transmitting / receiving devices 10. Furthermore, when a notification transmitting / receiving device 10 receives instruction information transmitted from another notification transmitting / receiving device 10, it can notify the presence of the fire extinguisher 5. In other words, the notification transmitting / receiving devices 10 can cooperate with each other to notify the presence of a fire extinguisher 5 near the fire extinguisher stand 3 from which the fire extinguisher 5 was removed. This allows a person performing firefighting activities to easily locate nearby fire extinguishers by simply removing one fire extinguisher, thereby enabling the rapid use of multiple fire extinguishers in succession. Furthermore, since the notification transmitting / receiving device 10 is attached to the fire extinguisher stand 3, the person performing firefighting activities is not forced to make unnecessary movements. Therefore, the notification transmitting / receiving device 10 of this embodiment makes it easy to carry out rapid and continuous firefighting activities. In particular, since large facilities such as warehouses and laboratory buildings contain a large amount of combustible materials, if the fire cannot be extinguished by initial firefighting activities, the extent of damage may be large. The notification transmitting / receiving device 10 of this embodiment makes it possible to easily carry out rapid and continuous initial firefighting activities. Therefore, when the notification transmitting / receiving device 10 of this embodiment is used in a large facility, it is possible to avoid large-scale fire damage. In other words, the notification transmitting / receiving device 10 of this embodiment is particularly effective for large facilities.

[0063] Furthermore, according to the alarm transmitting / receiving device 10, the detection unit 18 can reliably detect that the fire extinguisher 5 has been removed from the fire extinguisher stand 3. Furthermore, when a weight sensor is used as the detection unit 18, the fire extinguisher 5 is placed on the detection unit 18, and therefore the detection unit 18 does not interfere with the lateral or upward movement of the fire extinguisher 5. Therefore, when the detection unit 18 is a weight sensor, it can reliably detect the removal of the fire extinguisher 5 without interfering with the removal of the fire extinguisher 5 from the fire extinguisher stand 3.

[0064] Furthermore, according to the alert transmitting / receiving device 10, when the fire extinguisher 5 is removed from the fire extinguisher stand 3 and power is generated by the self-power generating unit 34, instruction information can be transmitted to the outside using power including the power obtained by power generation by the self-power generating unit 34. Therefore, according to the alert transmitting / receiving device 10 having the self-power generating unit 34, instruction information can be transmitted to the outside even if other power generating units (environmental power generating unit 36, power storage unit 38, commercial power source 40) are not included or are not functioning.

[0065] Furthermore, the notification transmission / reception device 10 can appropriately supply the power obtained by power generation by the energy harvesting unit 36 ​​to each component of the functional system 31. Therefore, the notification transmission / reception device 10 having the energy harvesting unit 36 ​​does not need to be connected to a commercial power source 40 (so-called cordless), does not need to charge the power storage unit 38, and can operate independently.

[0066] In particular, if the energy harvesting unit 36 ​​generates power from vibrations around the location where the fire extinguisher stand is placed, steady power generation can be easily achieved in a location with a lot of foot traffic. Also, in particular, if the energy harvesting unit 36 ​​generates power from light around the location where the fire extinguisher stand is placed, steady power generation can be easily achieved in a location where there is lighting or good sunlight.

[0067] Furthermore, the notification transmission / reception device 10 can store power in the power storage unit 38. Therefore, the notification transmission / reception device 10 having the power storage unit 38 can stably supply power appropriately to each component of the functional system 31 while power is stored in the power storage unit 38. This also makes it possible for the notification transmission / reception device 10 to temporarily operate even when the supply of power from the commercial power source 40 or the like is stopped. Furthermore, by storing the power generated by the energy harvester 36 in the power storage unit 38, power can be supplied to each component of the functional system 31 even during periods when it is difficult for the energy harvester 36 to generate power, and the notification transmission / reception device 10 can operate independently.

[0068] Furthermore, according to the notification transmitting / receiving device 10, the light emitting unit 28 can make the presence of the fire extinguisher 5 known by light. Therefore, according to the notification transmitting / receiving device 10, the presence of the fire extinguisher 5 can be made known, for example, regardless of the volume of noise around the fire extinguisher stand 3. Furthermore, even if the area around the fire extinguisher stand 3 is dark or difficult to see due to nighttime or smoke from a fire, the presence of the fire extinguisher 5 can be made known.

[0069] Furthermore, the notification transmitting / receiving device 10 can make the user aware of the presence of the fire extinguisher 5 by sound using the sound generating unit 30. Therefore, the notification transmitting / receiving device 10 can make the user aware of the presence of the fire extinguisher 5 even in an environment where the fire extinguisher 5 cannot be directly seen due to an obstacle or the like.

[0070] Furthermore, according to the notification transmitting / receiving device 10, the notification unit 26 notifies the presence of the fire extinguisher 5 until the fire extinguisher 5 is removed from the fire extinguisher stand 3. Therefore, according to the notification transmitting / receiving device 10, it is possible to prevent the notification from continuing even after the fire extinguisher 5 is removed from the fire extinguisher stand 3.

[0071] 2. Second embodiment The second embodiment is the same as the first embodiment except for a partial change in the configuration of the notification transmitting / receiving device 10. Therefore, in the description of the second embodiment, the description that overlaps with the first embodiment may be omitted.

[0072] As described above, the timing at which the self-generating unit 34 generates electricity can be said to be the timing at which the fire extinguisher 5 is removed from the fire extinguisher stand 3, and the self-generating unit 34 can essentially play the same role as the detection unit 18.

[0073] Therefore, in the notification transmitting / receiving device 10 of the second embodiment, when power is generated by the self-power generating unit 34, the transmitting unit 22 transmits instruction information to the outside under the control of the control unit 12. For this reason, the detection unit 18 is omitted in the notification transmitting / receiving device 10 of the second embodiment.

[0074] Fig. 4 is a flow diagram showing an example of the processing of the control unit 12 of the notification transmission / reception device 10 of the second embodiment. The flow diagram shown in Fig. 4 starts, for example, when the notification transmission / reception device 10 is started up or the fire extinguisher 5 is installed in the fire extinguisher stand 3. Basically, the processing flow is the same as that of the notification transmission / reception device 10 of the first embodiment, with steps S3 and S6 being replaced by steps S7 and S8 in the notification transmission / reception device 10 of the second embodiment.

[0075] Specifically, when notification of the presence of the fire extinguisher 5 starts in step S2, the control unit 12 proceeds from step S2 to step S7. In step S7, the control unit 12 determines whether or not power generation by the self-power generation unit 34 has been performed.

[0076] If the determination in step S7 is "NO", that is, if power generation by the self-power generation unit 34 is not being performed, the control unit 12 repeats the determination in step S7. On the other hand, if the determination in step S7 is "YES", that is, if power generation by the self-power generation unit 34 is being performed, the control unit 12 proceeds to step S4.

[0077] If the determination in step S1 is "NO," that is, if no instruction information has been received from the outside, the control unit 12 proceeds from step S1 to step S8. In step S8, the control unit 12 determines whether power generation has been performed by the self-power generation unit 34.

[0078] If the determination in step S8 is "NO", that is, if power generation by the self-power generation unit 34 is not being performed, the control unit 12 returns the process from step S8 to step S1. On the other hand, if the determination in step S8 is "YES", that is, if power generation by the self-power generation unit 34 is being performed, the control unit 12 proceeds the process from step S8 to step S5.

[0079] The flow chart shown in FIG. 4 is an example, and the order of the steps can be changed as desired as long as the same effect is obtained.

[0080] According to the notification transmitting / receiving device 10 of the second embodiment, the self-power generating unit 34 alone can determine the timing when the fire extinguisher 5 is removed from the fire extinguisher stand 3. Therefore, according to the notification transmitting / receiving device 10 of the second embodiment, the self-power generating unit 34 functions as both a power source and a detector, so that the notification transmitting / receiving device 10 can be realized with a simple configuration using a small number of parts.

[0081] 3. Fire extinguisher stand equipped with an alarm transmitter / receiver 5 is a perspective view showing an example of the configuration of a fire extinguisher stand 50 equipped with the notification transmitting / receiving device 10. In describing the fire extinguisher stand 50, descriptions that overlap with those of the notification transmitting / receiving device 10 described above may be omitted.

[0082] The fire extinguisher stand 50 is a fire extinguisher stand that is integrally equipped with the alarm transmitting / receiving device 10. Therefore, the fire extinguisher stand 50 has an external linkage function, an alarm function, etc. Note that the control unit 12 and the like are not shown in FIG.

[0083] 5, the alarm transmitting / receiving device 10 has a plurality of light emitting units 28 provided on the side surfaces of the side panels of a fire extinguisher stand 50, and a sound generating unit 30 provided at the top of the side panels. The fire extinguisher stand 50 also has a detection unit 18, a self-power generating unit 34, and an energy-power generating unit 36 ​​provided at its bottom.

[0084] In this way, the fire extinguisher stand 50 that is integrally provided with the alarm transmitting / receiving device 10 can have a large range for the light emitting unit 28 and the sound generating unit 30, thereby realizing more reliable alarms.

[0085] 4. Notification transmitting device The notification transmitting / receiving device 10 in the above embodiment has an integrated function of transmitting instruction information in response to the removal of the fire extinguisher 5 and a function of receiving the instruction information and issuing an alert, but these functions may be separated into a notification transmitting device 60 and a notification receiving device 70. First, an embodiment of the notification transmitting device 60 will be described.

[0086] 6 is a block diagram showing an example of the electrical configuration of the notification transmitting device 60. In describing the notification transmitting device 60, components that overlap with those of the notification transmitting / receiving device 10 are given the same reference numerals, and overlapping descriptions may be omitted.

[0087] The notification transmitting device 60 is a device attached to the fire extinguisher stand 3 on which the fire extinguisher 5 is placed, and mainly includes components corresponding to the external linking function of the notification transmitting / receiving device 10.

[0088] The notification transmitting device 60 includes a control unit 12, a transmission unit 22, a power supply circuit 32, and a self-power generating unit 34. The control unit 12 is electrically connected to the transmission unit 22 and the power supply circuit 32 via a circuit such as a bus. The power supply circuit 32 is also electrically connected to the self-power generating unit 34 via a circuit such as a bus.

[0089] In the notification transmission device 60, the control unit 12 and the transmission unit 22 belong to the functional system 31, and the power supply circuit 32 and the self-power generation unit 34 belong to the power supply system 39. Note that the connection between the notification transmission device 60 and the commercial power supply 40 is omitted. Also, the energy harvesting unit 36 ​​and the power storage unit 38 are omitted from the power supply system 39 of the notification transmission device 60. Therefore, the notification transmission device 60 is temporarily started up by the power obtained by power generation by the self-power generation unit 34.

[0090] When the fire extinguisher 5 is removed from the fire extinguisher stand 3, the notification transmitting device 60 is temporarily activated by the power generated by the self-power generating unit 34, and uses that power to transmit instruction information to the outside.

[0091] In other words, in the alarm transmitting device 60, when the fire extinguisher 5 is removed from the fire extinguisher stand 3 and power is generated by the self-power generating unit 34, the transmitting unit 22 uses the power obtained by the power generation by the self-power generating unit 34 to transmit instruction information to the outside.

[0092] In addition, when the alarm transmitting device 60 is connected to a commercial power source 40 or is equipped with an environmental power generation unit 36 ​​or the like, and each component of the functional system 31 receives a continuous supply of power, the alarm transmitting device 60 uses power including the power obtained by power generation by the self-power generation unit 34, as described above, to transmit instruction information to the outside.

[0093] Furthermore, when each component of the functional system 31 receives a continuous power supply, the functional system 31 may further include a detection unit 18, or may include the detection unit 18 instead of the self-power generation unit 34. Furthermore, when the alarm transmitting device 60 includes the detection unit 18, the alarm transmitting device 60 can transmit instruction information to the outside by detecting the removal of the fire extinguisher 5 from the fire extinguisher stand 3 with the detection unit 18.

[0094] 5. Notification receiving device 7 is a block diagram showing an example of the electrical configuration of the notification receiving device 70. In describing the notification receiving device 70, components that overlap with those of the notification transmitting / receiving device 10 are given the same reference numerals, and overlapping descriptions may be omitted.

[0095] The notification receiving device 70 is a device attached to the fire extinguisher stand 3 on which the fire extinguisher 5 is placed, and is mainly equipped with components corresponding to the notification function of the notification transmitting / receiving device 10.

[0096] The notification receiving device 70 includes a control unit 12, a detection unit 18, a reception unit 24, a notification unit 26, a power supply circuit 32, an energy harvesting unit 36, and a power storage unit 38. The control unit 12 is electrically connected to each of the detection unit 18, the reception unit 24, the notification unit 26, and the power supply circuit 32 via a circuit such as a bus. The power supply circuit 32 is also electrically connected to the energy harvesting unit 36 ​​and the power storage unit 38 via a circuit such as a bus.

[0097] In the notification receiving device 70, the control unit 12, the detection unit 18, the reception unit 24, and the notification unit 26 belong to a functional system 31, and the power supply circuit 32, the energy harvesting unit 36, and the power storage unit 38 belong to a power supply system 39.

[0098] When the receiving unit 24 of the alarm receiving device 70 receives instruction information transmitted from the outside, the alarm unit 26 notifies the presence of the fire extinguisher 5. Specifically, when the receiving unit 24 receives instruction information transmitted from the outside, the alarm receiving device 70 continues to notify the presence of the fire extinguisher 5 until the detection unit 18 detects that the fire extinguisher 5 has been removed from the fire extinguisher stand 3.

[0099] Furthermore, in the notification receiving device 70, during a period when the energy harvesting unit 36 ​​is able to generate power, a portion of the power obtained by the power generation is supplied to the power storage unit 38, and during a period when it is difficult for the energy harvesting unit 36 ​​to generate power, the power stored in the power storage unit 38 is supplied appropriately to each component of the functional system 31. The notification receiving device 70 may be connected to a commercial power source 40.

[0100] Furthermore, the notification receiving device 70 may include a self-power generation unit 34 instead of the detection unit 18. In this case, when instruction information transmitted from the outside is received by the receiving unit 24, the notification receiving device 70 notifies the presence of the fire extinguisher 5 until power generation is performed by the self-power generation unit 34.

[0101] When the notification transmitting device 60 and the notification receiving device 70 are attached to different fire extinguisher stands 3, instruction information is transmitted and received between these devices. In other words, instruction information is not transmitted and received between the notification transmitting device 60 and the notification receiving device 70 attached to the same fire extinguisher stand 3.

[0102] 6. Variations The specific configurations of the respective embodiments are merely examples, and aspects of the present invention are not limited to the configurations shown in the respective embodiments.

[0103] For example, as long as the notification transmitting / receiving device 10 in the above embodiment can perform the above-described functions, there may be at least one power source for supplying power to the functional system 31. In this case, there is an advantage that the number of parts can be reduced and a simpler configuration can be achieved.

[0104] Furthermore, the type of detection unit 18 is not particularly limited as long as it can detect the removal of a fire extinguisher 5 from the fire extinguisher stand 3. The detection unit 18 may be, for example, a distance sensor that measures the distance to the fire extinguisher 5. Alternatively, it may be, for example, a photoelectric sensor that includes a light-emitting unit and a light-receiving unit and detects the presence or absence of the fire extinguisher 5 based on the presence or absence of received light.
