Abstract
Description
[Technical Field]
[0001] The present invention relates to a portable anomaly detector. [Background technology]
[0002] Conventionally, portable anomaly detectors that can be used by users personally include portable fire detectors that detect fires that occur in monitored spaces (see, for example, Patent Document 1) and portable carbon monoxide detectors that detect carbon monoxide that occurs in monitored spaces (see, for example, Patent Document 2).
[0003] The main uses of portable abnormality detectors are, in the case of fire detectors, for example, to detect fires in guest rooms at hotels and other accommodations, and in the case of carbon monoxide detectors, for example, to detect carbon monoxide generated by stoves and other fire-generating appliances when users use them in their own rooms or inside tents at campsites. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 62-263455 [Patent Document 2] Microfilm of Utility Model Application No. 53-139114 (Utility Model Application No. 55-55752) Summary of the Invention [Problem to be solved by the invention]
[0005] Portable anomaly detectors are small, portable cases that contain a detection unit that detects abnormalities such as fires and carbon monoxide emissions, an alarm unit that issues an alarm, and a battery to power the detection and alarm units.They can be installed anywhere by the user, which is an advantage over fixed detectors that are permanently installed in a fixed location.
[0006] However, the installation location is not necessarily optimal for the user in terms of both detection and alarm. For example, from the viewpoint of detection, it is preferable to install the device in a location away from the user (for example, when detecting fires, it is preferable to install the device in a high place such as near the ceiling), while from the viewpoint of alarm, it may be preferable to install the device near the user (for example, when the alarm is set by vibration, it is preferable to install the device close enough to the user that the vibration is noticeable).
[0007] SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a portable anomaly detector that can be installed in a location that is suitable for both detection and alarm. [Means for solving the problem]
[0008] This invention is a portable anomaly detector comprising: an anomaly detection unit, a detection device unit having a case in which the anomaly detection unit is housed, and which emits a detection signal indicating an abnormality when the anomaly detection unit detects an abnormality occurring in the monitored space; an alarm unit, a case in which the alarm unit is housed, separate from the case of the detection device unit, and which issues an alarm of an abnormality from the alarm unit when it receives the detection signal of an abnormality transmitted from the detection device unit; wherein the detection device unit does not include an alarm unit that issues an alarm of an abnormality, and the alarm device unit does not include an anomaly detection unit that detects an abnormality occurring in the monitored space.
[0009] In the portable anomaly detector of the present invention, signals may be sent and received between the detection device unit and the alarm device unit wirelessly or via a wired connection. The detection device unit may include a fire detection unit and / or a carbon monoxide detection unit as the anomaly detection unit, and may be configured to emit a fire and / or carbon monoxide detection signal when the fire detection unit and / or carbon monoxide detection unit detects a fire and / or carbon monoxide generation in the monitored space. The alarm device unit may be configured to issue a fire and / or carbon monoxide generation alarm from the alarm unit when it receives a fire and / or carbon monoxide generation detection signal from the detection device unit. The alarm device unit may also include a sound generation unit and / or a vibration generation unit as the alarm unit, and may be configured to issue an alarm by sound and / or vibration from the sound generation unit and / or vibration generation unit.
[0010] The portable abnormality detector of the present invention may be configured to include one or more of the detection device sections and one or more of the alarm device sections.
[0011] Furthermore, in the portable anomaly detector of the present invention, the alarm device unit may further include an operating unit, and by operating the operating unit, an operating signal may be sent to the detection device unit, thereby enabling operation of the detection device unit. The detection device unit may further include an operating unit, and by operating the operating unit, an operating signal may be sent to the alarm device unit, thereby enabling operation of the alarm device unit. A portable information terminal may be used as the alarm device unit. The alarm device unit may further include a fan that draws air from the outside of the case to the inside. The alarm device unit may further include rectifying means that regulates the flow of air drawn by the fan. The case of the alarm device unit may be provided with a hanging portion, and an air inlet hole that introduces air from the outside to the inside may be provided in a portion that faces downward when hung by the hanging portion. [Effects of the Invention]
[0012] In this invention, the detection device unit and the alarm device unit are housed in separate cases, so the user can install the detection device unit and the alarm device unit in any desired location, and can install the detection device unit in a location that is suitable for detection, and the alarm device unit in a location that is suitable for alarm.
[0013] Therefore, according to the present invention, it is possible to provide a portable anomaly detector that can be installed in a location that is suitable for both detection and alarm. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0015] Below, with reference to the drawings, an example of an embodiment of a portable abnormality detector of this invention will be described, taking as an example a case in which the detection device unit includes a fire detection unit and a carbon monoxide detection unit as an abnormality detection unit, and the alarm device unit includes a speaker (an example of a sound generating unit) and a vibration generating unit as an alarm unit.
[0016] [Entire detector] The portable anomaly detector 1 is composed of a detection device unit 2 and an alarm device unit 3 (see FIG. 1). The detection device unit 2 includes an anomaly detection unit 21 (including a smoke detection unit 21A (an example of a fire detection unit) and a carbon monoxide detection unit 21B) that detects anomalies occurring in the monitored space, a control unit 22, a wireless communication unit 23, a battery 24, and a portable case 25 that houses the anomaly detection unit 21, the control unit 22, the wireless communication unit 23, and the battery 24 (see FIG. 1). The alarm device unit 3 includes an alarm unit 31 (including a speaker 31A (an example of a sound generation unit) and a vibration generation unit 31B) that issues an alarm when an abnormality occurs, a control unit 32, a wireless communication unit 33, a battery 34, and a portable case 35 that is physically separate from the case 25 of the detection device unit 2 and that houses the alarm unit 31, the control unit 32, the wireless communication unit 33, and the battery 34 (see FIG. 1).
[0017] The detection device unit 2 and the alarm device unit 3 are configured such that the former does not have an alarm unit, while the latter does not have an abnormality detection unit, but they cooperate by sending and receiving signals via wireless communication between each other's wireless communication units 23 and 33, and when the detection device unit 2 detects an abnormality, the alarm device unit 3 issues an alarm.
[0018] In the portable anomaly detector 1, the detection device unit 2 and the alarm device unit 3 are housed in separate cases. This allows the user to install the detection device unit 2 and the alarm device unit 3 in any desired location, allowing the user to install the detection device unit 2 in a location that is suitable for detection, and the alarm device unit 3 in a location that is suitable for alarming.
[0019] [Each device part] Detection device section Target of detection More specifically, the detection device section 2 includes a smoke detection section 21A (an example of a fire detection section) for detecting fires and a carbon monoxide detection section 21B as components that constitute the abnormality detection section 21. The smoke detection section 21A detects smoke to detect fires, and the carbon monoxide detection section 21B detects carbon monoxide. In other words, the abnormality detection section 21 detects fires and carbon monoxide that occur in the space to be protected.
[0020] The abnormality to be detected by the abnormality detection unit 21 may be either fire or carbon monoxide, or may detect other abnormalities instead of or in addition to fire and carbon monoxide, and a corresponding detection unit may be provided. Furthermore, for fire detection, another detection unit such as a heat detection unit may be provided instead of or in addition to the smoke detection unit 21A.
[0021] ·Device configuration The alarm device unit 2 is box-shaped and is configured to house, in a small case 25 that can be easily carried by the user, the abnormality detection unit 21, which includes a smoke detection unit 21A and a carbon monoxide detection unit 21B, a control unit 22, a wireless communication unit 23, and a battery 24 that serves as the power source for driving them (see Figure 2; however, the control unit 22 and wireless communication unit 23 are not shown).
[0022] Smoke detection unit The smoke detector 21A has a function of detecting the concentration of smoke and outputting a detection signal. The smoke detector 21A may be, for example, a photoelectric type detector including a light-emitting element 21Aa and a light-receiving element 21Ab, in which the light-emitting element 21Aa's light is reflected diffusely by smoke particles and detected by the light-receiving element 21Ab (see FIG. 2). The smoke detector 21A further includes a light-shielding wall 21Ac (see FIG. 2). The light-shielding wall 21Ac has a function of preventing the light emitted from the light-emitting element 21Aa from directly entering the light-receiving element 21Ab.
[0023] Carbon monoxide detector Carbon monoxide detector 21B has a function of detecting the concentration of carbon monoxide and outputting a detection signal. Carbon monoxide detector 21B may be of a semiconductor type, an electrochemical type, or the like.
[0024] ·Smoke introduction hole Case 25 is provided with smoke introduction holes 25a for introducing smoke from the outside of case 25 to the inside (see FIG. 2). In the illustrated example, smoke introduction holes 25a are provided on part of the circumferential surface of case 25, but they may be provided on the entire circumferential surface, or on the upper or lower surface instead of or in addition to the circumferential surface.
[0025] Wireless Communication Unit The wireless communication unit 23 has a function of performing wireless communication with the wireless communication unit 33 of the alarm device unit 3. Specifically, for example, it has a function of transmitting detection signals of fire occurrence and carbon monoxide generation to the wireless communication unit 33 of the alarm device unit 3.
[0026] Control unit The control unit 22 has a function of performing various controls and processes on the smoke detection unit 21A, the carbon monoxide detection unit 21B, the wireless communication unit 23, and the like.
[0027] ···Storage part Although not shown, the control unit 22 includes a memory unit that stores a smoke concentration threshold (e.g., 10%) for a fire alarm level and a carbon monoxide concentration threshold (e.g., 50 ppm) for a carbon monoxide alarm level.
[0028] Judgment process Control unit 22 has a function of determining whether the concentration of smoke detected by smoke detection unit 21A has reached the alarm level for a fire, and also has a function of determining whether the concentration of carbon monoxide detected by carbon monoxide detection unit 21B has reached the alarm level for carbon monoxide generation. That is, control unit 22 compares the detection signals output from smoke detection unit 21A and carbon monoxide detection unit 21B with the respective concentration thresholds stored in the memory unit, and determines whether the alarm levels for a fire and carbon monoxide generation have been reached.
[0029] Outgoing call control When the control unit 22 determines that the fire alarm level has been reached, it controls the wireless communication unit 23 to transmit a fire detection signal, and when it determines that the carbon monoxide generation alarm level has been reached, it controls the wireless communication unit 23 to transmit a carbon monoxide generation detection signal.
[0030] The detection signal transmitted from the wireless communication unit 23 may be a uniform signal common to both fire occurrence and carbon monoxide generation.
[0031] ·Alarm device section Alarm mode The alarm device unit 3 includes a speaker 31A (an example of a voice generating unit) and a vibration generating unit 31B as components that make up the alarm unit 31. The speaker 31A has a function of notifying the user of the occurrence of an abnormality by emitting a beep alarm sound or a voice message, and the vibration generating unit 31B has a function of notifying the user of the occurrence of an abnormality by emitting vibrations. Note that instead of the speaker 31A, a buzzer (an example of a voice generating unit) may be provided, and the user may be notified of the occurrence of an abnormality by emitting only a beep alarm sound.
[0032] ·Device configuration The alarm device unit 3 is box-shaped and is configured by housing the alarm unit 31, which consists of a speaker 31A and a vibration generating unit 31B, a control unit 32, a wireless communication unit 33, and a battery 34 that serves as the power source for driving them, in a small case 35 that is easily portable by the user (see Figure 3; however, the control unit 32 and wireless communication unit 33 are not shown).
[0033] Speaker The speaker 31A can be of various types that convert an electrical signal into sound and output audio.
[0034] Vibration generating part As the vibration generating section 31B, for example, a vibration motor or the like can be used.
[0035] Wireless Communication Unit The wireless communication unit 33 has a function of performing wireless communication with the wireless communication unit 23 of the detection device unit 2. Specifically, for example, it has a function of receiving detection signals of fire occurrence and carbon monoxide generation transmitted from the wireless communication unit 23 of the detection device unit 2.
[0036] Control unit The control unit 32 has a function of performing various controls and processes for the speaker 31A, the vibration generating unit 31B, the wireless communication unit 33, and the like (including the return operation unit 36 described later).
[0037] Alarm control When the wireless communication unit 33 receives a detection signal transmitted from the wireless communication unit 23 of the detection device unit 2, the control unit 32 controls the speaker 31A and the vibration generating unit 31B to emit an alarm corresponding to the detection signal. In other words, when a detection signal indicating a fire is received, the control unit 32 controls the speaker 31A to emit an alarm sound or a voice message corresponding to the fire, and also controls the vibration generating unit 31B to emit vibrations.
[0038] The alarm sound or voice message emitted by speaker 31A and the vibration emitted by vibration generating unit 31B may be the same for both fire and carbon monoxide generation.
[0039] Reset operation unit The alarm device section 3 further includes a reset operation section 36 that resets the alarm device section 3 from a state in which the detection device section 2 detects a fire or carbon monoxide and the alarm device section 3 issues an alarm to a state in which the alarm section 3 is constantly monitoring.
[0040] The reset operation unit 36 has a function of stopping the alarm from the speaker 31A and the vibration generating unit 31B when operated to reset, and also has a function of causing the wireless communication unit 33 to transmit a reset signal to the wireless communication unit 23 of the detection device unit 2. In other words, it has a function of resetting the alarm device unit 3 itself to the state during regular monitoring, and also has a function of resetting the detection device unit 2 to the state during regular monitoring.
[0041] Instead of or in addition to the reset operation unit 36 of the alarm device unit 3, the detection device unit 2 may be provided with a reset operation unit that resets the detection device unit 2 from a state in which the detection device unit 2 detects a fire or carbon monoxide and the alarm device unit 3 issues an alarm to a state in which it is under constant monitoring.
[0042] Furthermore, the reset operation unit 36 of the alarm device unit 3 and the reset operation unit provided in the alarm device unit 2 may be configured to perform an operation different from the reset operation.
[0043] [Battery type] The batteries 24 and 34 can be either primary or secondary batteries.
[0044] Here, the detection device unit 2 does not have an alarm unit such as a speaker, and the alarm device unit 3 does not have a detection unit such as a smoke detector. In both devices, power consumption can be reduced accordingly. Therefore, a battery with a small capacity can be used, such as a small, thin battery such as a button battery.
[0045] The illustrated example shows a case where button batteries are used as the batteries 24, 34 (see FIGS. 2 and 3). By using such small, thin batteries, the cases 25, 35 can be made smaller and thinner accordingly.
[0046] [Wireless communication method] Various wireless communication methods such as Wi-fi (registered trademark) and Bluetooth (registered trademark) can be used as the method of wireless communication between the wireless communication units 23, 33 of the detection device unit 2 and the alarm device unit 3. Since the detection device unit 2 and the alarm device unit 3 are installed at a relatively short distance, such as in the same room, it is sufficient that at least short-range wireless communication is possible.
[0047] [Number and combination of each device] The number of detection device units 2 and alarm device units 3 may be one or more. Alternatively, one of them may be one and the other may be more than one. Furthermore, when there are more than one detection device units 2, they may include one that is equipped with only the smoke detection unit 21A and one that is equipped with only the carbon monoxide detection unit 21B, and when there are more than one alarm device units 3, they may include one that is equipped with only the speaker 31A and one that is equipped with only the vibration generation unit 31B.
[0048] [Usage example] As an example of how the portable anomaly detector 1 can be used to detect fires, it can be used in guest rooms of hotels and other lodging facilities (as a backup in addition to the fire detectors installed in the guest rooms). Also, when it is used to detect carbon monoxide, it can be used when using a stove or other fire device indoors at home or in a camping tent. In either case, the user can install the detection device unit 2 in a location suitable for detecting smoke and carbon monoxide, and can install the alarm device unit 3 in a location suitable for alarms (the user can also wear it on themselves).
[0049] [How to use] For example, when using portable anomaly detector 1 to detect carbon monoxide in a camping tent, the user installs detector unit 2 in a location suitable for detecting carbon monoxide in the tent at a campsite, and alarm unit 3 in a location suitable for noticing the alarm, or wears one on the user's person. Then, the user turns on the power switches of both units 2 and 3 to activate monitoring. When carbon monoxide is generated by using a stove or other fire source in the tent and its concentration reaches the alarm level, detector unit 2 detects the carbon monoxide concentration at the alarm level using carbon monoxide detector unit 21B and, based on the judgment of control unit 22, outputs a carbon monoxide detection signal from wireless communication unit 23. Alarm unit 3 receives the carbon monoxide detection signal output from the wireless communication unit of detector unit 2 using its own wireless communication unit 33. Based on the received signal, alarm unit 3 issues a carbon monoxide detection alarm from speaker 31A and vibration generator 31B. The user immediately notices the alarm and can take necessary measures, such as ventilating the room.
[0050] [Example of change] ·Insect net In the detection device section 2, an insect screen 25c can be provided at the portion of the case 25 where the smoke introduction hole 25a is provided to prevent insects from entering inside.
[0051] Intake fan In the alarm device unit 2, an intake fan 26 may be provided inside the case 25 to draw outside air into the case 25 through the smoke inlet hole 25a, and the smoke detection unit 21A may be positioned between the smoke inlet hole 25a and the intake fan 26 (see Figure 4).
[0052] A sirocco fan that exhausts air in a direction perpendicular to the direction of intake air can be used as intake fan 26 (see FIG. 4). Case 25 can be provided with exhaust holes 25b that exhaust air drawn in by intake fan 26 to the outside (see FIG. 4), and the exhaust path between intake fan 26 and exhaust holes 25b inside case 25 can be arranged to avoid other built-in components such as carbon monoxide detector 21B and battery 24 (see FIG. 4).
[0053] The case 25 may also be provided with an insect screen 25c at the exhaust hole 25b to prevent insects from entering inside (see FIG. 4).
[0054] ·Rectification part In addition, a rectifying section 27 that regulates the flow of smoke from the smoke inlet hole 25a to the smoke detection section 21A can be provided inside the case 25 between the smoke inlet hole 25a and the smoke detection section 21A (see Figure 4).
[0055] Hanging part The detection device unit 2 may be provided with a hanging part so that it can be installed by hanging. The hanging part may be provided on the case 25. As the hanging part, a hanging tool that allows for easy and secure hanging, such as a carabiner 28 (a hanging tool having a ring-shaped hanging part with an opening and closing part) can be used (see FIG. 4).
[0056] Furthermore, when the hanging portion is provided on the case 25, it can be provided in a position such that when the case 25 is hung by the hanging portion, the smoke introduction hole 25a provided on the case 25 faces downward (see Figure 4).
[0057] Although not shown, the alarm device unit 3 may also be provided with a hanging part on the case 35 similar to that of the detection device unit 2. In this way, the user can use the hanging part to hang and install the alarm device unit 3, and can also use the hanging part to attach the alarm device unit 3 to their own body.
[0058] Stand The alarm device unit 3 can be provided with a stand 35a so that the case 35 can be placed vertically or at an angle (see FIG. 5(a)). The stand 35a can be made foldable as in the illustrated example (see FIG. 5(b)). If it is made foldable, it can be folded down toward the case 35 body when not in use, and the stand 35a can be prevented from getting in the way when carrying it around (see FIG. 5(b)).
[0059] ·Charging terminal The detection device unit 2 and the alarm device unit 3 can use secondary batteries as the batteries 24, 34, and the cases 25, 35 can be provided with input terminals 25d, 35d for receiving power during charging (see Figure 6).
[0060] As a charging mode, power may be supplied directly from an external power source to input terminals 25d, 35d via a charging cable or connector, but power may also be supplied via either the detection device unit 2 or the alarm device unit 3, and an output terminal for power supply for this purpose may be provided in either device unit or both device units. The power supply output terminal 35e provided on the case 35 of the alarm device unit 3 is one example, and can be used when supplying power via the alarm device unit 3 (see Figure 6). A commercial power source or a battery can be used as the external power source.
[0061] The above describes an embodiment of the portable anomaly detector of the present invention with reference to the drawings, but the present invention is not limited to the above embodiment, and modifications to the configuration are possible within the scope of the gist of the invention.
[0062] Use of mobile information devices For example, instead of the alarm device unit 3, a general-purpose portable information terminal such as a smartphone or a tablet PC may be used.
[0063] Wired communication Although wireless communication is performed by the wireless communication units 23 and 33 provided in the detection device unit 2 and the alarm device unit 3, wired communication may also be used. For example, wired communication may be performed by connecting the input terminals 25d and 35d via a cable or connector. [Explanation of symbols]
