Abstract
Description
[Technical Field]
[0001] The present invention relates to a spot-type fire detector. [Background technology]
[0002] A spot-type fire detector is a type of fire detector that detects fires at a single location (spot) where the detector is installed.Some detectors work in conjunction with other devices to form automatic fire alarm systems, while others form residential fire alarms that can also sound an alarm on their own.
[0003] Among these types of spot-type fire detectors, there are some that are provided with a storage unit capable of storing various types of information (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Patent Publication No. 2021-89671 Summary of the Invention [Problem to be solved by the invention]
[0005] The technology disclosed in the above-mentioned Patent Document 1 proposes storing model information and test history information of a smoke detector (fire detector) in a memory unit, and displaying this information on the display unit of the tester during testing.
[0006] Conventional spot-type fire detectors have not been equipped with a display unit for the information stored in the memory unit, so the only way to display the information stored in the memory unit is to display it on the display unit of an external device such as a tester, as in the technology disclosed in Patent Document 1.
[0007] SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a spot-type fire detector that is capable of displaying information stored in a memory unit. [Means for solving the problem]
[0008] This invention is a spot-type fire detector comprising a memory unit and a screen display unit, wherein the screen display unit is capable of displaying at least one of the following information stored in the memory unit: type information of the fire detector, individual identification information, operating status information, operating mode information, fault information, alarm history information, inspection history information, usage period information, and replacement information.
[0009] The present invention also provides a spot-type fire detector that includes a memory unit and a screen display unit, and the screen display unit is capable of displaying the type information of the fire detector stored in the memory unit, making it possible to omit the attachment of a sticker that displays the type information of the fire detector.
[0010] The present invention also provides a spot-type fire detector that includes a memory unit and a screen display unit, and that is capable of displaying fire determination mode information for a combined fire detector that is stored in the memory unit.
[0011] In this invention, the screen display unit may be capable of displaying information using a QR code (registered trademark). The screen display unit may be provided exposed on the surface of the sensor body or the mounting base. A film for displaying information may be attached to the screen of the screen display unit, and the information displayed by the film may be visible when the screen of the screen display unit is turned off, but may be invisible when the screen of the screen display unit is turned on. [Effects of the Invention]
[0012] In this invention, the sensor itself is provided with a screen display unit capable of displaying information stored in the memory unit.
[0013] Therefore, according to the present invention, it is possible to provide a spot-type fire detector that is capable of displaying information stored in the storage unit. [Brief explanation of the drawings]

[0015] Below, an embodiment of the spot-type fire detector of this invention will be described with reference to the drawings, taking as an example a case where the spot-type fire detector is used to form an automatic fire alarm system together with other devices and to form a smoke detector that detects smoke and fires.
[0016] The spot-type fire detector of the present invention can be applied not only to components constituting automatic fire alarm systems, but also to components constituting, for example, residential fire alarms that can issue an alarm on their own, etc. Furthermore, in terms of the type of fire detection method, the spot-type fire detector can be applied not only to components constituting smoke detectors, but also to components constituting heat detectors that detect fires by detecting heat, flame detectors that detect fires by detecting flames, and composite detectors (such as those that detect heat and smoke) that detect fires by detecting multiple types of physical quantities caused by fires.
[0017] [Basic configuration] The fire detector 1 has a case-shaped detector body 2, and is mounted in an exposed state via an exposed mounting base 6 on the installation surface, such as the ceiling T, of a fire-protected object such as a building (see Figure 1(b)). It is installed in the fire-protected object together with a receiver and a local sound device, and together with these devices, it constitutes an automatic fire alarm system, and further constitutes a spot-type fire detector that detects fires in a single local area (spot) at the installation location.
[0018] In addition, the fire detector 1 is provided with a smoke detector 3 for detecting fires inside the detector body 2, and the smoke detector 3 detects smoke introduced through the smoke inlet 3a (insect screen not shown) to detect a fire (see Figures 1(a) and (b)), thereby constituting a smoke detector.
[0019] [Screen display] The fire detector 1 is provided with a storage unit (not shown) capable of storing various types of information, and also with a screen display unit 4 capable of displaying the information stored in the storage unit.
[0020] [Display content] ·Various information The information that can be displayed on the screen display unit 4 can be information about the detector itself, and specifically, for example, type information (such as type by detection method or type by sensitivity), individual identification information (address information), operating status information (such as monitoring state or fire detection state), operating mode information (such as current operating mode when the operating mode is variable), fault information (such as the results of automatic testing, details of any faults discovered), alarm history information (such as past fire detection history), inspection history information (such as the date of past inspection), usage period information (such as the period from installation to the present), replacement information (such as recommended replacement time), etc.
[0021] Any one of these pieces of information may be displayed on the screen display unit 4, or a plurality of pieces of information may be displayed.
[0022] Type information Here, conventionally, a type indication sticker is attached to a fire detector at the time of manufacture to indicate the type of fire detector (types based on differences in detection method, types based on differences in sensitivity, etc.) In recent years, fire detectors have become increasingly smaller, making it difficult to attach the sticker.
[0023] If the screen display unit 4 is capable of displaying type information indicating the type of the sensor itself, it is possible to omit the attachment of a type display sticker. In other words, the work step of attaching the sticker during manufacturing can be omitted.
[0024] Judgment mode information When the screen display unit 4 is capable of displaying operation mode information, the operation mode information can be, for example, fire determination mode information when the fire detector 1 is a combined detector. Specifically, for example, when the fire detector 1 is a combined heat and smoke detector, the operation mode information can be the current determination mode out of a mode that determines a fire by detecting both heat and smoke, a mode that determines a fire by detecting either heat or smoke, a mode that determines a fire by detecting heat only, or a mode that determines a fire by detecting smoke only.
[0025] [Display mode] Information can be displayed on the screen display unit 4 in various ways, such as text and graphics.
[0026] [QR Code (registered trademark)] The display of information on the screen display unit 4 can be performed using a QR code (registered trademark). For example, among the information that can be displayed on the screen display unit 4, unchanging information such as detector type information can be converted into a QR code (registered trademark) and stored in the storage unit, so that it can be displayed on the screen display unit 4 as a QR code (registered trademark).
[0027] [Display device] Various display devices such as a liquid crystal display can be used as the screen display unit 4. The screen shape may be rectangular (see FIGS. 1(a) and (b)), or may be other shapes such as circular (see FIG. 2).
[0028] [Touch panel] The screen display unit 4 may be a touch panel type and may be operable by touch. In this case, for example, touching the touch panel may enable turning on and off the screen of the screen display unit 4 or changing the information displayed on the screen display unit 4.
[0029] [Placement] Front part of the detector body The screen display unit 4 may be provided so as to be exposed on the surface of the sensor main body 2. Specifically, for example, it may be provided so as to be exposed on the surface of the front portion 2a of the sensor main body 2 that faces the monitored space when installed. In this case, it may be provided so as to be exposed on the surface of a peripheral portion 2ab outside a central portion 2aa (the portion in which the smoke detection unit 3 is located) that protrudes forward of the front portion 2a (see FIGS. 1(a) and 1(b)), or it may be provided so as to be exposed on the surface of the central portion 2aa (see FIG. 2).
[0030] -Side part of the sensor body or mounting base If the sensor main body 2 is attached to the installation surface in an exposed type manner, the screen display unit 4 may be exposed on the surface of the side portion 2b of the sensor main body 2 or the side portion 6b of the exposed type mounting base 6, although this is not shown in the figure.
[0031] Front part of the mounting base When the fire detector 1 is mounted to an installation surface such as a ceiling T in a recessed state via a recessed mounting base 7, the fire detector 1 is mounted to the installation surface such as a ceiling T in a partially recessed state (see FIG. 3). In this case, if the recessed mounting base 7 has a front surface 7a that faces the monitored space when installed, similar to the front surface 2a of the detector main body 2, the screen display unit 4 may be provided exposed on the surface of the front surface 7a (see FIG. 3).
[0032] [Information display film] The screen display unit 4 may have attached thereon an information display film 5 that displays unchanging information about the fire detector 1, such as detector type information. In this case, the information displayed by the information display film 5 may be visible when the screen of the screen display unit 4 is turned off (see FIG. 4(a)), and may be invisible when the screen is turned on (see FIG. 4(b)). For example, the information may be printed on the information display film 5 using a printing technique that achieves this.
[0033] By attaching such an information display film 5, it is possible to display unchanging information such as the type of detector on the screen even when the screen display unit 4 is in the off state, and when the screen display unit 4 is in the screen lit state, it is possible to display other information stored in the memory unit on the screen.
[0034] [Configuration change example] The above describes an embodiment of the spot-type fire 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.
[0035] For example, instead of constituting a smoke detector, the spot-type fire detector 1 may be a heat detector that detects a fire by detecting heat, a flame detector that detects a fire by detecting flame, or a composite detector (such as one that detects heat and smoke) that detects a fire by detecting multiple types of physical quantities caused by a fire. Also, instead of constituting an automatic fire alarm system together with other devices, it may be a residential fire alarm on its own. [Explanation of symbols]
