Description

[0001] The invention relates to an arrangement and method for the commissioning of fire alarm systems.

[0002] When installing a fire alarm system, the physical devices (e.g., fire detectors) must be matched with their digital counterparts. This is typically done by specially trained service technicians who use floor plans to assign fire detectors to rooms or groups of fire detectors.

[0003] There are various methods by which fire detectors can be assigned to a digital model today, e.g. via the wiring sequence of the detectors, via the serial number of the detectors, or via programming the detectors according to a plan.

[0004] German patent application DE 10 2018 204 370 A1 discloses a method and a system for authorizing the communication (e.g., data connection) of a network node (e.g., IoT device) of a communication network (e.g., IP network). Authorization for communication by the network node occurs only if the geographical position of the network node and the position of a defined (certified) mobile communication device (e.g., smartphone) substantially coincide.

[0005] US patent application US 2016 / 0205721A1 discloses a positioning system for installing devices on a campus or in buildings, whereby a mobile device can be assigned a position indicator. A building information model is used as a reference for determining the position. A location name for an installed device can be derived from the building information model, since the mobile device is located at the position of the installed device during the device's placement.

[0006] German patent application DE 10 2018 113 461 A1 discloses a tool for setting up and maintaining detectors (e.g., alarms) for hazard warning systems.

[0007] German patent application DE 10 2017 217 760 A1 discloses a method and an arrangement for commissioning and / or maintaining a control unit for field devices in building automation. A communication link is established between the control unit and a user's mobile communication device. The mobile communication device is configured to query an identification code, current configuration data, and current data points of the control unit via this communication link. A data point represents the state of a parameter of a field device. The mobile communication device is further configured to communicate with a central location via another communication link, where a BIM model of the corresponding building is stored.The identification code is used to correlate the current data of the control device with the data of the control device stored in the BIM model. Based on the current configuration data, the current data points, and the data of the control device stored in the BIM model, the mobile communication device is configured to provide the user with specific instructions.

[0008] European patent EP 3 594 919 B1 discloses a system and a method for assigning device addresses in an alarm system, such as a fire alarm system, with interactive address assignment for commissioning.

[0009] European patent application EP 3 206 174 A1 discloses a method and an arrangement for commissioning a building automation system for a building, wherein a device installed or to be installed in the building comprises an identification code with device-specific data, wherein the identification code is captured by a user's mobile communication terminal, wherein a building plan for the building is displayed on a screen of the mobile communication terminal, wherein, by means of user input on the mobile communication terminal, the installed or to be installed device is assigned to a location on the building plan and / or to other installed or to be installed devices on the building plan, wherein the assignment is stored in the building automation system.

[0010] All known methods have in common that a trained service technician must manually assign a detector to a representation of that detector in a model. This is error-prone and time-consuming.

[0011] It is therefore the object of the present invention to provide an arrangement and method for the commissioning of fire alarm systems in which the assignment of physical detectors to a model is carried out automatically.

[0012] The task is solved by an order for the commissioning of a fire alarm system, comprising: a central server set up to store a building plan and / or a building information model (BIM) for a building; a control unit which can be connected via a detector line to a plurality of connected detectors (e.g. hazard detectors and / or fire detectors), wherein the control unit can be connected to the central server via a suitable initial communication link, where the control unit is configured to obtain a unique identification (e.g. a unique identification number or a unique identification identifier) ​​of one of the detectors via the detector line when it is installed, the control unit is further configured to send the received identification of the respective installed detector via the first communication link to the central server for storage in the digital building model (BIM); where the central server is set up to determine the installation location of the detector upon receiving the detector's identification and to store this location accordingly in the building information model (BIM) and / or in the building plan, the control unit (SG) is a test device which is set up to ensure operation of the detector line (ML) with a sufficient range of functions for commissioning the detectors (M1 - M3).

[0013] It is advantageous for the building information model (BIM) or building plan to be stored in a suitable notation (e.g., IFC, Industry Foundation Class; OMT, Object Modelling Technique) and saved in a suitable digital format. The control unit can, for example, be a test device that ensures the operation of a detector line with a sufficient range of functions for commissioning the detectors. The control unit can also provide the power supply required for the installation.

[0014] To determine the installation location of each detector, it is advantageous for it to have a GPS or indoor GPS function. When the detector is inserted into its base, its installation location is also transmitted to the control unit. The communication links can be, for example, suitable radio and / or IP connections. When a detector is installed in the detector line or in a detector base located within the line, a connection can be established, triggering the transmission of the identification data to the control unit.

[0015] A first advantageous embodiment of the invention lies in the fact that the installation location of the detector is determined based on the respective identification and building plans and / or configuration data of the fire alarm system stored on the server. The installation location of a detector can be determined using existing configuration and planning data that is already stored on the server or to which the server has access.

[0016] A further advantageous embodiment of the invention is that the arrangement further comprises: a mobile communication device (e.g. tablet computer or smartphone) that can be connected to the central server via a suitable second communication connection (e.g. radio; WLAN); The mobile communication device is configured to determine its current location (Pos) using an indoor positioning system and / or its own internal sensors, and is further configured to transmit this location (Pos) to the central server. The indoor positioning system can determine the location based on, for example, iBeacons, BLE (Bluetooth Low Energy), and / or WLAN. Mobile communication devices are widely used and can be upgraded with suitable hardware and / or software, for example, by installing appropriate apps. Positioning functionality can also be implemented using internal sensors and components of the mobile communication device, such as a gyroscope, magnetic field analysis, and occasional recalibration via GPS or comparison with BIM data.

[0017] A further advantageous embodiment of the invention lies in the fact that the central server is configured to assign the specific location to the installation location of the detector based on a temporal coincidence between the received identification of the installed detector and the location of a user's (e.g., commissioning technician's) mobile communication device. If the central server receives the identification and the location simultaneously or quasi-simultaneously (e.g., within a time span of 1 to 10 seconds, particularly 1 to 5 seconds), a reliable and valid assignment of the identification and location of a detector is possible. Advantageously, this assignment occurs automatically, i.e., without user intervention. Advantageously, the user's mobile communication device is registered with the server. Multiple mobile communication devices belonging to the user can also be registered with the server.This also applies to the mobile communication devices of other users. Registration with the server can be done, for example, by providing IP addresses and / or mobile phone numbers, and / or through special certificate-based mechanisms or verifications.

[0018] A further advantageous embodiment of the invention lies in the fact that the mobile communication device is configured to transmit its current location at defined time intervals (e.g., 2 sec, 5 sec, 10 sec, 15 sec, 30 sec). The shorter the time intervals, the more accurate the determination of the location for an installed detector.

[0019] A further advantageous embodiment of the invention lies in the fact that the central server is configured to request the current location of the mobile communication device upon receiving the identification. This can be done by an automatic request (e.g., by a corresponding command or signal) from the server to the mobile communication device. The request from the server can also be sent to the user of the mobile communication device via a message, for example, via a messenger service. Advantageously, such messages, commands, or signals are automatically generated by the server when it receives an identification. Advantageously, the message includes the corresponding identification of the reporting device.The user can compare the received identification with the identification of the installed detector, and if there is a match, send the current location to the server via the mobile communication device.

[0020] A further advantageous embodiment of the invention lies in the fact that each detector is configured, upon installation, to recognize a user's (e.g., commissioning engineer's) mobile communication device via short-range communication (e.g., Bluetooth, RFID, NFC), to read the current location of the mobile communication device, and to send this information, along with the detector's identification, to the control unit for forwarding to the central server. In this embodiment, no communication link between the mobile communication device and the server is required.

[0021] A further advantageous embodiment of the invention lies in the fact that the control unit is configured to perform the functionality of a fire alarm control panel. This allows the full functionality of a fire alarm control panel for the detector line to be tested using the control unit.

[0022] A further advantageous embodiment of the invention lies in the fact that the control unit is a fire alarm control panel that can be connected to the central server via a suitable third communication link (e.g., a suitable radio link). This allows the fire alarm control panel to be installed and tested together with the detectors.

[0023] A further advantageous embodiment of the invention lies in the fact that the central server is implemented as a cloud server. This allows the central server to be easily scaled, for example, with regard to the number of connected fire alarm control panels or connected detector lines. A cloud server can provide its services, for example, as SaaS (Software as a Service) or as PaaS (Platform as a Service). The data connection to the cloud server can be established via suitable communication links (e.g., WLAN, radio).

[0024] A further advantageous embodiment of the invention lies in the fact that the installation of a detector in the detector line is effected by an electrical connection and / or a data connection between the detector and the detector line. By means of appropriate electronic components and / or measurements of electrical parameters on the detector line, it can be easily determined whether an electrical connection and / or a data connection has been established between the detector and the detector line.

[0025] A further advantageous embodiment of the invention lies in the fact that the detector line is adequately supplied with electricity for data communication during commissioning. The detector line is supplied with a suitable line voltage. Advantageously, the applied line voltage is within a range that allows for safe wiring work on the detector line. If the applied line voltage is, for example, essentially 30 volts (e.g., in the range of 30 ± 4 V), wiring work on the detector line can be carried out safely.

[0026] The task is further solved by a procedure for commissioning a fire alarm system, comprising: where, after a detector has been installed in a detector line, this detector sends a unique identification (e.g. a unique identifier) ​​to a control unit of the detector line, in particular to a fire alarm control panel of the detector line; wherein the control unit sends the received identification of the respective installed detector via a suitable communication link to a central server for storage in a digital building model and / or a digital building plan, wherein the control unit is a test device which is set up to ensure operation of the detector line with a sufficient range of functions for commissioning the detectors; The central server, upon receiving the identification, determines the detector's installation location based on this identification and stores it in the building information model and / or the building plan. Ideally, the building information model (BIM) or the building plan is stored in a suitable notation (e.g., IFC, Industry Foundation Class; OMT, Object Modelling Technique) and saved in a suitable digital format. The control unit can be, for example, a test device or a fire alarm control panel. The control unit ensures the operation of the detector line with a sufficient range of functions for commissioning the detectors. The control unit can also provide the necessary power supply for installation. Ideally, each detector has GPS or indoor GPS for determining its installation location.Advantageously, when each detector is inserted into its base, the installation location is transmitted to the control unit. The communication links can be, for example, suitable radio and / or IP connections. When a detector is installed in the detector line or in a detector base located in the detector line, a contact can be established, triggering the transmission of the identification data to the control unit.

[0027] A further advantageous embodiment of the invention lies in the fact that the determination of the detector's installation location is based on the respective identification and building plans and / or configuration data of the fire alarm system stored on the server. The installation location of a detector can be determined using existing configuration and planning data that is already stored on the server or to which the server has access.

[0028] A further advantageous embodiment of the invention lies in the fact that a mobile communication device determines its current location via an indoor positioning system (IPS) and transmits it to the central server. The central server then determines the installation location of the detector based on a temporal coincidence between the received identification of the installed detector and the location of a user's mobile communication device. If the central server (e.g., a cloud server) receives the identification and the location simultaneously or quasi-simultaneously (e.g., within a time span of 1 to 10 seconds, particularly 1 to 5 seconds), a reliable and valid assignment of the identification and location of a detector is possible. Advantageously, this assignment occurs automatically, i.e., without user intervention. Advantageously, the user's mobile communication device is registered with the server.Multiple mobile communication devices belonging to the user can be registered with the server. This also applies to the mobile communication devices of other users. Registration with the server can be achieved, for example, by providing IP addresses and / or mobile phone numbers, and / or through certificates or other suitable credentials. The indoor positioning system can determine the respective position based on, for example, iBeacons, BLE (Bluetooth Low Energy), and / or WLAN. The indoor positioning system can also be implemented using internal sensors and components of the mobile communication device, such as a gyroscope, magnetic field analysis, and occasional recalibration via GPS or comparison with BIM data.

[0029] Mobile communication devices are widespread and can be upgraded with suitable hardware or software, e.g. by installing suitable apps.

[0030] The invention and advantageous embodiments of the present invention are explained with reference to the following figure. This figure shows: Fig. 1. An exemplary representation of exemplary arrangements for the commissioning of a fire alarm system, Fig. 2. A first exemplary flowchart for a procedure for commissioning a fire alarm system, Fig. 3 a second exemplary flowchart for a procedure for commissioning a fire alarm system, and Fig. 4 a third exemplary flowchart for a procedure for commissioning a fire alarm system.

[0031] Fig. Figure 1 shows an exemplary arrangement for the commissioning of a fire alarm system. The exemplary arrangement according to Fig. Figure 1 shows a fire alarm control panel (BZ) with a detector line (ML). The detector line (ML) includes example detectors (M1-M3). These detectors can be of different types, such as fire detectors, gas detectors, and temperature sensors. Detectors M1-M3 can also be combined detectors (for detecting different hazards). The detectors M1-M3 are typically connected to the detector line (ML) electrically and / or via data connections using detector bases. The detector line (ML) can have a bus, ring, or star topology.

[0032] The exemplary detector line ML also includes an optional control unit SG, which is electrically and / or data-wise connected to the detector line ML via a suitable connection mechanism VM (e.g., bus coupling mechanism). The control unit SG can be used, for example, for commissioning the detector line ML and / or for testing purposes. Advantageously, the control unit SG has the functionality of a fire alarm control panel (BZ). The control unit SG can also be a fire alarm control panel (BZ). Advantageously, the detector line ML is configured for supplying power to detectors M1-M3 and for bidirectional data communication between detectors M1-M3 and / or between detectors M1-M3 and the control unit SG and / or the fire alarm control panel (BZ). For example, after successful installation in the detector line ML, a detector M1-M3 can transmit its respective unique identification ID (e.g.,Send the identification number (identification identifier) ​​on the detector line ML to the control unit SG and / or the fire alarm control panel BZ.

[0033] The exemplary representation according to Fig. Figure 1 shows a central server S. This central server S can, for example, be part of a building management system. The central server S ideally has access to storage media, such as a database (DB), where, among other things, a building information model (BIM) and / or a digital building plan (GP) and / or configuration data (KD) of the fire alarm control panel (BZ) are stored in a suitable notation. The building information model (BIM) can, for example, be stored in IFC (Industry Foundation Class) notation. However, the building information model (BIM) can also be stored in a suitable object modeling notation (e.g., OMT). The same applies to a digital building plan (GP).

[0034] The central server S can, for example, be implemented as a cloud server, with suitable hardware and software components, as well as suitable communication mechanisms.

[0035] In the exemplary representation according to Fig. 1. The central server S is connected to the control unit SG via the communication link KV1 (e.g. radio link) and to the fire alarm control panel BZ via the communication link KV3 (e.g. radio link).

[0036] A user B (e.g., commissioning engineer, installer) can insert a detector M1-M3 into the corresponding detector socket of the detector line ML using a suitable installation device IG (e.g., detector picker, test picker). Successful installation of a detector M1-M3 can be confirmed by appropriate contact (electrical and / or data connection). The detector line ML is supplied with a suitable voltage for installation and commissioning.

[0037] The installation device IG is advantageously equipped with suitable communication mechanisms (e.g. NFC, Bluetooth, WLAN) for data communication with detectors M1 - M3 and / or for data communication with a mobile communication device MG (e.g. smartphone, tablet computer) of the user.

[0038] The mobile communication device MG is advantageously connected to the central server S via a suitable communication link KV2. Communication links KV1 - KV3 are preferably bidirectional.

[0039] The location of the mobile communication device (MG) can be determined or provided for the respective mobile communication device (MG) via a suitable indoor positioning system (IPS) and / or via internal sensors (including barometer, accelerometer, gyroscope, magnetometer).

[0040] Since the Global Positioning System (GPS) does not function indoors, other positioning technologies are used for indoor positioning (IPS). The most well-known are Wi-Fi and beacons. Indoor positioning with beacons (e.g., iBeacon (Apple) or Eddystone (Google)) offers significant advantages for projects that require high accuracy and involve mobile electronic devices. Beacons (e.g., based on BLE, Bluetooth Low Energy) are typically transmitters in client-based methods or procedures.

[0041] Special techniques for indoor positioning are needed wherever GPS doesn't work, primarily inside buildings. As mentioned above, the most common methods are Wi-Fi and Bluetooth beacons. Additionally, or optionally, the various sensors of the smartphone (including barometer, accelerometer, gyroscope, and magnetometer) are usually used, which can further improve the accuracy of the positioning.

[0042] Since the infrastructure for an indoor positioning system is typically not available at the time a fire alarm control panel is commissioned, the functionality and / or sensors of a mobile communication device (e.g., a smartphone) can be advantageously used for position determination. This position can be repeatedly compared with a GPS-based starting value and the building plans (e.g., when GPS reception is available at a window, or when climbing stairs or passing through a door).

[0043] The present invention is advantageously applicable even without an indoor positioning system (IPS). Advantageously, the detectors themselves include mechanisms for determining their respective position.

[0044] However, there are basically two different techniques for indoor positioning: device-based (client-side) positioning and infrastructure-based (server-side) positioning.

[0045] Client-side positioning is usually implemented using beacons or WLAN access points. These devices regularly transmit signals. The end device analyzes the signal characteristics and compares them to a reference database.

[0046] This requires an app to which messages can also be sent (return channel). The position is determined directly on the device, offering the user maximum data privacy. This method is typically used for classic indoor navigation via smartphone app.

[0047] Infrastructure-based (server-side) positioning reverses the process described above. A Wi-Fi-enabled device / tag or a Bluetooth beacon emits signals (MAC address) that are detected by specific hardware and forwarded to a server. In the backend, the collected measurement data is compared, interpolated, and displayed in other systems. This method has the advantage that even devices without an app can be detected and analyzed. With server-side installations, asset tracking, trajectory analysis, and security solutions can be implemented.

[0048] Bluetooth technology itself is not new. However, only recently have the energy-saving Bluetooth variant BLE (Bluetooth Low Energy) opened up expanded application possibilities. Bluetooth beacons are relatively inexpensive (approximately three to 30 euros), can be powered for up to two years with a button cell battery or over ten years with larger batteries, and have a range of up to 30 meters.

[0049] A first exemplary arrangement for the commissioning of a fire alarm system includes: a central server S, set up to store a building plan GP and / or a building information model BIM for a building; a control unit SG which can be connected to a detector line ML with a plurality of detectors M1 - M3 connected to it via data technology, where the control unit SG can be connected to the central server S via a suitable first communication link KV1, where the control unit SG is configured to obtain a unique identification ID of a detector M1 - M3 via the detector line ML when a detector M1 - M3 is installed, where the control unit SG is further configured to send the received identification ID of the respective installed detector M1 - M3 via the first communication link KV1 to the central server S for storage in a digital building model BIM; where the central server S is set up to determine the installation location of the detector M1 - M3 upon receiving the identification ID of the detector M1 - M3 and to store it accordingly in the building information model BIM and / or in a building plan GP.

[0050] Advantageously, detectors M1 to M3 and / or their respective bases each have a GPS or indoor GPS module to determine the installation location of the detector. When the detector is inserted into the base, this module transmits the installation location to the central server S. The transmission of the installation location and / or the unique identification ID from each detector M1-M3 to the central server S can occur directly (e.g., via a direct radio connection between the detector and the server) and / or indirectly (e.g., via the control unit SG, the fire alarm control panel BZ, and / or the mobile communication device MG).

[0051] The installation location of each detector M1 - M3 is advantageously determined based on the respective identification ID and on the building plans GP and / or configuration data KD of the fire alarm system stored in the server S.

[0052] The first exemplary arrangement also advantageously includes: a mobile communication terminal MG, which can be connected to the central server S via a suitable second communication connection KV2; wherein the mobile communication terminal MG is set up to determine its respective location position Pos via an indoor positioning system IPS and send it to the central server S.

[0053] Advantageously, the central server S is set up based on the temporal coincidence of the received identification ID of the installed detector M1 - M3 and the location Pos of the mobile communication device MG of a user B, which assigns the specific location Pos to the installation location of the detector M1 - M3.

[0054] The mobile communication device (MG) is advantageously configured to send its current location (Pos) at defined time intervals (e.g., 5 sec, 10 sec, 15 sec, 30 sec). The current location (Pos) is then transmitted to the server (S).

[0055] It is advantageous to set up the central server S to request the current location position Pos of the mobile communication device MG upon receiving the identification ID.

[0056] It is advantageous for each detector M1 - M3 to be set up to recognize a user's mobile communication device MG (e.g. commissioning engineer) via short-range communication (e.g. Bluetooth, RFID, NFC) during its installation, to read the location position Pos of the recognized mobile communication device MG and to send it together with the identification ID of the detector M1 - M3 to the control unit SG for forwarding to the central server S.

[0057] It is advantageous to configure the control unit SG to perform the functionality of a fire alarm control panel BZ.

[0058] The control unit SG is advantageously a fire alarm control panel BZ, which can be connected to the central server S via a suitable third communication link KV3.

[0059] A second exemplary arrangement for the commissioning of a fire alarm control panel (BZ) with a detector line (ML) with a plurality of connected detectors (M1-M3) comprises: a central server S, set up to store a digital building plan GP and / or a building information model BIM for a building; a mobile communication terminal MG, which can be connected to the central server S via a suitable second communication connection KV2; wherein the mobile communication terminal MG is set up to determine its respective location position Pos via an indoor positioning system IPS and send it to the central server S; an installation device IG for inserting detectors M1 - M3 into the detector line ML, wherein the installation device IG is configured to read the respective identification ID of a detector M1 - M3 after insertion and to transmit it to the mobile communication terminal MG (e.g. WLAN, NFC, Bluetooth); where the mobile communication device MG is further configured to send the received identification ID of the respective installed detector M1 - M3 together with the location position Pos of the mobile communication device MG via the second communication connection KV2 to the central server S for storage in a digital building model BIM and / or in a building plan GP.

[0060] A further advantageous embodiment of the present invention lies in a fire alarm control panel (BZ) with a detector line (ML) with a plurality of detectors (M1-M3) connected thereto, in particular fire detectors. where the fire alarm control panel (BZ) can be connected to a central server (S) via a suitable third communication link (KV3). where the fire alarm control panel (BZ) is set up to receive a unique identification ID of a detector M1 - M3 via the detector line ML when a detector M1 - M3 is installed, where the fire alarm control panel (BZ) is set up to send the received identification ID of the installed detector M1 - M3 via the third communication link (KV3) to the central server (S) for storage in a digital building model (BIM) and / or a digital building plan (GP).

[0061] The fire alarm control panel (BZ) is advantageously configured to automatically synchronize information about installed detectors (M1-M3) with the digital building model (BIM) and / or the digital building plan (GP) of the central server (S). This ensures that the fire alarm control panel and the central server always access synchronized and consistent data (especially configuration data). Synchronization can be scheduled, for example, at defined times or intervals. It can also be event-driven (e.g., upon configuration changes).

[0062] It is advantageous for the central server S to be implemented as a cloud server with appropriate hardware and software components and suitable communication interfaces and communication means for the arrangements described above.

[0063] For the arrangements described above, it is advantageous to install a detector M1 - M3 in the detector line ML by means of an electrical connection and / or a data connection between detector M1 - M3 and detector line ML.

[0064] For the arrangements described above, it is advantageous that the detector line ML is adequately supplied with electricity for data communication during commissioning.

[0065] For the configurations described above, it is advantageous to equip the detector line ML with one or more wireless detectors M1-M3. It is also advantageous to configure the detector line ML for the data connection of one or more wireless detectors. Wireless detectors can communicate with each other and / or with the fire alarm control panel (BZ) and / or with a control unit (SG) via appropriate radio links. For communication with a mobile communication device (MG) and / or an installation device (IG) (e.g., detector picker), wireless detectors can have a suitable near-field communication mechanism (e.g., Bluetooth, NFC).

[0066] Fig. Figure 2 shows a first exemplary flowchart for a procedure for commissioning a fire alarm system, comprising: (VS1) wherein, after installation of a detector in a detector line, this detector sends a unique identification (ID) to a control device of the detector line, in particular to a fire alarm control panel of the detector line; (VS2) wherein the control unit sends the received identification (ID) of the respective installed detector via a suitable communication link to the central server for storage in a digital building model (BIM) and / or a digital building plan; (VS3) where, after receiving the identification, the central server determines the installation location of the detector based on the received identification and stores it in the building information model (BIM) and / or in the building plan.

[0067] The installation location of the detector is advantageously determined based on the respective identification and building plans and / or configuration data of the fire alarm system stored on the server.

[0068] Advantageously, a mobile communication device determines its location via an indoor positioning system and sends this to the central server, whereby the central server determines the installation location of the detector based on the temporal coincidence of the received identification of the installed detector and the location of a user's mobile communication device.

[0069] Fig. Figure 3 shows a second exemplary flowchart for the commissioning of a fire alarm system, comprising: (VS1') wherein, after installation of a detector in a detector line, this detector sends a unique identification to a user's mobile communication device; (VS2') wherein the mobile communication terminal sends the received identification of the respective installed detector together with its current location via a suitable second communication link to a central server for storage in a digital building model (BIM) and / or a digital building plan; (VS3') where, after receiving the identification and location, the central server determines the installation location of the detector and stores it in the building information model (BIM) and / or in the building plan.

[0070] Advantageously, after successful installation of a detector, this detector sends its unique identification to an installation device (e.g. test picker, test picker) for inserting the detectors; the installation device forwards the identification to the user's mobile communication device (e.g. via Bluetooth, NFC, WLAN); the user's mobile communication device sends the identification of the respective detector and the current location of the mobile communication device to the central server.

[0071] Fig. Figure 4 shows a third exemplary flowchart for a procedure for commissioning a fire alarm system, comprising: (VS1'') wherein, after successful installation of a detector in a detector line, this detector sends a unique identification to an installation device for inserting the detectors (M1 - M3); (VS2'') wherein the installation device sends the unique identifier to a user's mobile communication device; (VS3'') wherein the mobile communication terminal sends the received identification (ID) of the respective installed detector together with its current location via a suitable second communication link to a central server for storage in a digital building model (BIM) and / or a building plan; (VS4'') where, after receiving the identification and location, the central server determines the installation location of the detector and stores it in a digital building information model (BIM) and / or in a digital building plan.

[0072] It is advantageous to determine the respective location of the mobile communication device using an Indoor Positioning System (IPS).

[0073] The procedures according to Fig. 2 to 4 can be implemented using commercially available components (HW, SW) that are already available for building automation.

[0074] The central server S is advantageous for the in the Fig. The methods described in sections 2 to 4 are implemented as a cloud server with corresponding hardware and software components, as well as suitable communication interfaces and means. The central server S can, for example, be part of a building management system. The central server S advantageously has access to storage media, such as a database (DB), where, among other things, a building information model (BIM) and / or a digital building plan (GP) and / or configuration data (KD) of the fire alarm control panel (BZ) are stored in a suitable notation. The building information model (BIM) can, for example, be stored in IFC (Industry Foundation Class) notation. However, the building information model (BIM) can also be stored in a suitable object modeling notation (e.g., OMT). The same applies to a digital building plan (GP).

[0075] It is advantageous for those in the Fig. The procedures described in sections 2 to 4 involve the installation of a detector M1 - M3 into the detector line ML by means of an electrical connection and / or a data connection between detector M1 - M3 and detector line ML.

[0076] It is advantageous for those in the Fig. The procedures described in sections 2 to 4 ensure that the detector line ML is adequately supplied with electricity for data communication during commissioning.

[0077] Advantageously points for the in the Fig.The procedures described in sections 2 to 4 define the detector line ML as using exemplary hazard detectors M1-M3. Hazard detectors M1-M3 can be of different types, such as fire detectors, gas detectors, or temperature sensors. Hazard detectors M1-M3 can also be combined detectors (for detecting different hazards). Hazard detectors M1-M3 are typically connected electrically and / or via data connections to detector line ML using detector bases. Detector line ML can, for example, have a bus, ring, or star topology.

[0078] The mobile communication device used in the methods described above can be, for example, a smartphone or a tablet computer. The methods described above preferably use suitable radio connections and / or near-field communication methods (e.g., NFC, Bluetooth).

[0079] The indoor positioning system described above is advantageously a commercially available system. For example, the indoor positioning system can determine the position based on iBeacons, BLE (Bluetooth Low Energy), and / or WLAN. The indoor positioning system can also be implemented using internal sensors and components of the mobile communication device, such as a gyroscope, magnetic field analysis, and occasional recalibration via GPS or comparison with BIM data.

[0080] Mobile communication devices are widespread and can be upgraded with suitable hardware or software, e.g. by installing suitable apps.

[0081] The proposed invention is based, among other things, on the following assumptions and options: 1. The installer carries a mobile device connected to a central server, which uses an indoor positioning system to know its current position and transmits this position to the server at regular intervals, or can be requested by the server to transmit its position. 2. The detector line is already connected to a device that operates the line as a complete fire alarm control panel during installation. This device may explicitly be the fire alarm control panel itself, which would eliminate the need for a further installation step. However, this is not strictly necessary. This device is also connected to the central server. When a new detector is installed, it sends an ID, which uniquely identifies the detector, to the device, which then forwards this ID to the central server. 3. When the server receives notification that a new detector has been installed, it requests the installer's location. Using a) building plans and / or fire alarm system configuration data stored on the server, b) the installer's location, and c) the received detector ID, the server can, based on the temporal coincidence of the detector installation and the installer's location, assign the detector ID to the building plans and / or the fire alarm system configuration.

[0082] The described method thus allows the assignment of physical devices to their digital counterparts and / or to locations in building plans to be carried out fully automatically and without manual intervention. This eliminates the need for a specially trained service technician to manually identify and assign the detectors.

[0083] The following optional variants are possible, for example: A. The detector communicates with the installer's mobile device (e.g., via RFID tag in the detector and NFC) and thus establishes a link between the location and the detector's identification. A permanent connection to a central server, or even the existence of a central server itself, is not required in this case. B. A special device is used to install the detectors, which reads the ID of the detector and communicates with the installer's mobile device, thus establishing an association between detector ID and position.

[0084] The present invention offers, among other things, the following advantages / features: - A fault-prone, time-consuming and expensive workflow (also known as "detector localization") can be completely eliminated. - Pairing the detectors requires no special knowledge and can be done by the installer. - The installer's work progress can be tracked, which allows for more precise planning. Because the server contains information about the building and the fire alarm system configuration, and because the server is connected to the detector line and the installer's mobile device, it is easy to provide the installer with immediate feedback after installing a new detector, indicating whether the installation was successful and according to plan, or if there are any discrepancies (electrical problems on the line, inconsistencies between the installation and the plans / configuration data). This significantly simplifies troubleshooting, as errors are detected as soon as they occur. - Central server or cloud application on which floor plans and / or configuration data of the fire alarm system are stored and which communicates with the device according to a. and the mobile device according to and establishes an assignment of the detector or its ID to a location in the floor plan and / or the configuration of the fire alarm system based on the temporal coincidence of the message from the device that a new detector has been installed and the position according to the mobile device. - Savings on a complex, potentially difficult and error-prone work process (costs). - Improved predictability for the commissioning of a fire alarm system.
