Description
[0001] Method and arrangement for the visual inspection of fire detectors. The invention relates to a method and arrangement for the inspection of fire detectors. The invention further relates to a fire detector and a mobile communication terminal configured to carry out the method for the inspection of fire detectors. US 2007 / 0186618 A1 discloses a device for testing smoke and CO detectors mounted at an elevated location above a floor surface. The test device comprises a test chamber configured to fit over the detector to provide an enclosed delivery system during testing of the detector. The test device further comprises a holder connected in a resiliently cooperating relationship to the test chamber to receive and release test substances when the test chamber slides downwards to the bottom of the holder and when it is pressed against a wall or ceiling. The test device further comprisesa handle attached to one end of a telescopic rod, which is pivotally mounted on the test chamber to press the test chamber against a wall or ceiling above the detector to be tested. An identification reader or receiver / PDA attached to the telescopic rod is used to communicate with the test device, to identify the detector via an attached barcode, and to transmit the test results to a central location after the detector has been tested. Fire detectors must be visually inspected once or several times a year in accordance with applicable local guidelines ("local code of practice"). For this purpose, a trained person walks through the building and examines each installed fire detector. This involves a visual inspection to determine whether the fire detector still appears to be functional (e.g., not damaged, not heavily soiled, not covered, etc.), whether there are any structural defects in its immediate vicinity, and whether there are anyChanges have occurred (which could impede or delay smoke entry into the fire detector), or whether the room use still matches the fire detector's configured parameter set. Each inspected fire detector is checked off a list (paper or electronic checklist) either continuously or at the end of the inspection. However, this does not allow for verification of whether the inspector (e.g., service technician) found the fire detector, whether they looked at the correct fire detector, and / or whether they actually inspected it. There are also proposals to equip fire detectors with NFC, Wi-Fi, and Bluetooth beacons. Upon completion of an inspection, the fire detector transmits an ID (a unique identifying signal), which is received by an app on the inspector's smartphone. Bluetooth beacons require energy and, as an additional component of a fire detector, incur additional costs. Such proposed systems, however, are still expensive.and / or unreliable. The object of the present invention is to provide a cost-effective and easy-to-implement method for inspecting fire detectors. The object is achieved by a method for inspecting fire detectors, (VS1) wherein a fire detector to be inspected is provided with an individual first visual coding and / or wherein a label attached in the immediate vicinity of a fire detector to be inspected is provided with an individual second visual coding; (VS2) wherein a server is provided which provides configuration data and / or maintenance data of the fire detector to be inspected; (VS3) wherein a user's mobile communication terminal is configured to access the configuration data and / or maintenance data of the respective fire detector to be inspected via a suitable communication connection to the server and to communicate with the server, wherein themobile communication terminal is further configured to read the first visual coding of the fire detector to be inspected and / or the second visual coding in the direct vicinity of the fire detector to be inspected, wherein the individual first and / or second visual coding is uniquely assigned to a respective fire detector, and wherein the individual first and / or second visual coding comprises a detector ID; (V4) wherein the mobile communication terminal, such as a smartphone, a tablet or a mobile phone, is further configured to send the detector ID to the server via the communication connection; (V5) wherein the operating state and / or the maintenance state of the fire detector to be inspected is determined based on the individual first and / or second visual coding, the configuration data and / or the maintenance data of the fire detector to be inspected. In particular, the mobile communication terminal is configured toTo read the visual coding of the fire detector to be inspected, the user manually aligns an integrated (main) camera of the mobile communication device or smartphone during the inspection to the individual visual coding on the fire detector to be inspected and / or to a label with an individual visual coding attached in the direct vicinity of a fire detector being inspected. Currently available mobile communication devices, in particular smartphones, are capable of optically capturing and evaluating a barcode or a matrix code, such as a QR code, at a distance of up to 5 meters. "Direct proximity" refers to a distance of a label from an assigned fire detector in a range of 1 cm to 25 cm, in particular in a range of 5 cm to 15 cm. The method enables, among other things, a simple inspection and also a simpleVerification of the performance of an inspection of fire detectors or other hazard detectors. The process can be automated based on existing infrastructure. The individual visual coding is uniquely assigned to a fire detector. The visual coding can, for example, be attached to the outside of the fire detector housing. However, the visual coding can also be attached next to the fire detector. For example, a label attached in the immediate vicinity of the fire detector (e.g., detector identification number) can be provided with the individual visual coding assigned to the fire detector. The visual coding can, for example, be a QR code, a bar code, an alphanumeric identification code of the fire detector, or another form of machine-readable coding. The visual coding could also be a URL. The visual coding could also be a NaviLens code, such as aA colored QR code that can be read and evaluated using a corresponding app on a mobile communications device (e.g., a smartphone). The visual coding can also be designed so that it is invisible to the human eye. Such a design would not affect the optical design of the fire detector. The visual coding can be in the NIR (near infrared) or NUV (near UV) wavelength range, i.e., wavelength ranges that border the optical spectrum of the human eye. The visual coding can also be created using so-called IR ink; see Japanese patent application JP2002146254A. Furthermore, the applicant refers to the MIT publication "InfraredTags: Embedding Invisible AR Markers and Barcodes Using Low-Cost, Infrared-Based 3D Printing and Imaging Tools”, MD Dogan et al., ACM ISBN 978-1-4503-9157-3 / 22 / 04, https: / / doi.org / 10.1145 / 3491102.3501951. Maintenance data includes, for example, information aboutMaintenance work carried out (when was which maintenance carried out by whom? Chronological list of the maintenance and inspections carried out; results of functional tests; when were the batteries or rechargeable battery replaced; length of the maintenance intervals), reported alarms, reported false alarms. Configuration data includes, for example, the parameter settings for the fire detector, set sensitivity parameters for fire detection. The server has access to the maintenance data and the configuration data of the respective fire detectors and is set up to provide this data via suitable communication means (e.g. radio connection) for the mobile communication device or for an app on the mobile communication device. The maintenance data and configuration data of the fire detectors can, for example, be stored in a building information model (BIM) in a suitable database. The maintenance data and the configuration data of the fire detectors can, for example,via a building automation system (BAS) and / or a facility management system for the server or for the database. This can be done, for example, by entries in a corresponding management station. The maintenance data and the configuration data of the fire detectors can, however, also be made available to the server or for the database via a fire alarm control panel (panel) to which the fire detectors are connected. A first advantageous embodiment of the invention is that the determination of the operating status includes, in particular, a review of the performance of maintenance inspections. This makes it possible to check very quickly with a query whether the maintenance inspections scheduled for the respective fire detector have been carried out. Verification of performed maintenance inspections is thus possible. A further advantageous embodiment of the invention is that the determination of theThe operating status is determined on the server, in particular a cloud server. This can be done, for example, by an analysis or evaluation unit implemented in the server. The server is equipped with the appropriate processor, memory, and communication resources. Implementing the analysis or evaluation unit in a cloud server enables easy scaling or expansion of the analysis or evaluation unit according to new requirements. Optionally, the operating status can be determined on the mobile communication device (e.g., smartphone, tablet computer) using a dedicated app. The app can be downloaded to the mobile communication device. A further advantageous embodiment of the invention is that the server and / or the app of the mobile communication device are configured to generate a report, in particular a compliance report, on maintenance inspections performed on a fire detector.This makes it very easy to comply with national regulations or applicable local guidelines ("local code of practice") regarding the inspection of fire detectors, and to demonstrate compliance with them. A further advantageous embodiment of the invention lies in a fire detector configured to carry out the method according to the invention. Fire detectors configured to operate the method according to the invention allow, among other things, the verification and / or documentation of a completed inspection to be carried out efficiently and safely. A further advantageous embodiment of the invention lies in a mobile communications terminal configured to carry out the method according to the invention. Mobile communications terminals (e.g., smartphones) usually have suitable onboard resources or can be upgraded with a corresponding app to carry out the method according to the invention. The problem is further solvedby an arrangement comprising: a detector line with fire detectors, wherein the fire detectors are each provided with an individual first visual coding and / or wherein a label with an individual second visual coding is attached to the fire detectors in the immediate vicinity, in particular for unambiguous assignment to the respective, directly adjacent fire detector; a server that provides configuration data and / or maintenance data of the respective fire detectors; a mobile communication terminal of a user that is configured to access the configuration data and / or the maintenance data of a respective fire detector via a suitable communication connection to the server and to communicate with the server, wherein the mobile communication terminal is further configured to display the respective first visual coding of respective fire detectors and / or the respective second visual coding in the immediate vicinity of theThe individual first and / or second visual coding can be read by the respective fire detectors to be inspected; whereby, based on the respective individual first and / or second visual coding, the configuration data, and / or the maintenance data of a respective fire detector, the operating status and / or maintenance status of this respective fire detector can be determined by suitable evaluation means. The infrastructure for implementing or retrofitting the arrangement is usually already present in today's buildings or building automation systems. The individual first and / or second visual coding can easily be uniquely assigned to a fire detector. The first visual coding can, for example, be affixed to the outside of the fire detector housing. The second visual coding can also be affixed next to the fire detector, typically as a detector identification on a corresponding label. Preferably, either the fire detectors of a detector line are provided with a first visual codingor the labels attached in the immediate vicinity of the fire detectors to be inspected are provided with an individual second visual coding. In particular, a first or a second visual coding on the respective fire detector or in the immediate vicinity thereof can be uniquely assigned to the respective fire detector. A further advantageous embodiment of the invention is that the individual first and / or second visual coding is attached to the outside of the housing of the fire detector. The second visual coding can, for example, be attached to the label in addition to a visible detector identification. A further advantageous embodiment of the invention is that the individual first and / or second visual coding has a wavelength range of NIR (Near Infrared) or NUV (Near UV). The individual first visual coding is uniquely assigned to a fire detector. The visual coding can, for example, be on theThe outside of the fire detector's housing must be attached. The outside of the housing of the fire detector to be inspected is opposite the mounting side. The second visual code can also be attached next to the fire detector. For example, a label (e.g., detector identification number) attached in the immediate vicinity of the fire detector can be provided with the individual second visual code assigned to the fire detector. The first and / or second visual code can be, for example, a QR code, a bar code, an alphanumeric identification code of the fire detector, or another form of machine-readable code. The first and / or second visual code could also be a URL. The first and / or second visual code could also be a NaviLens code, such as a colored QR code that can be read and evaluated using a corresponding app on a mobile communications device (e.g., smartphone).The advantage is that the first visual coding is visibly attached when the fire detector is mounted, i.e., visible from the outside. Optionally, the first and / or second visual coding can also be designed in such a way that it is not visible to the human eye, but is nevertheless readable using appropriate optics. Such a design would not affect the optical design of the fire detector or the label with the detector identification. The first visual coding can be in the NIR (Near Infrared) or NUV (Near UV) wavelength range, i.e., wavelength ranges that border on the optical spectrum of the human eye. The first and / or second visual coding can also be created using a so-called IR ink, see Japanese patent application JP2002146254A. The first coding can, for example, be applied on a transparent sticker or on a sticker in the same housing color as the fire detector (e.g., white) with such a UV orThe second code can be printed with IR ink, which is then affixed to the visible exterior of the fire detector. The second code can also be printed, for example, on a transparent sticker or on a sticker in the same color as the label (such as red) using such UV or IR ink, which is then affixed to the label outside the detector identification plate.
