Definitions
- the invention relates to a method for automatically testing a fire alarm system, in particular a method for automatically testing a central unit comprised by the fire alarm system.
- a fire alarm system comprises in a manner known per se at least one fire alarm and at least one device (central unit) functioning as a central unit in the fire alarm system.
- These devices are connected to a bus line, sometimes also referred to below as a transmission line, and at least communicatively connected by means of the bus line.
- the central unit is hereinafter referred to as the control center (fire alarm center) for short.
- the head office is sometimes also referred to as a panel.
- the bus line is used to transmit data and / or energy to the fire detectors connected to the bus line.
- the fire alarms connected to the bus line, the bus line itself and at least one control center connected to the bus line together form a fire alarm system or a fire alarm system.
- the control center has so far been manually switched to a test mode. Subsequently, at least individual fire alarms included in the fire alarm system are triggered manually and an operator checks a display that is received at the control center and shown there, resulting in each case on the basis of such triggering. In some states it is for one Such a test requires the manual triggering of all fire alarms included in the respective fire alarm system.
- An object of the invention is accordingly to provide a method for automatically carrying out such a test.
- the fire alarm system comprises a control center as devices, fire detectors connected to the control center via a transmission line and the transmission line, the following is provided:
- Each fire detector sends a message to the control center in the event of a so-called triggering and based on the triggering.
- the fire alarm system can be triggered due to an alarm situation (fire and / or smoke).
- the triggering is a fire triggering.
- the triggered fire detector sends a message to the control center based on the triggering.
- the automatic test triggering of a fire detector by the control center takes place when the control center sends a stimulus to the fire detector.
- a stimulus is thus the event that is generated and output in the control center in order to trigger a test alarm on a fire detector.
- such a stimulus is a field bus telegram.
- a message received by the control center and pending there is processed by the control center and triggers a response from the control center to the message.
- a predefined or predefinable number of fire detectors is triggered.
- the fire alarm system is tested in two process sections, namely first in a process section referred to as the recording mode and at a later point in time in a process section referred to as the test mode.
- At least one resulting reaction from the control center, in particular in the control center, is stored for each triggered fire alarm.
- the fire alarm test can be triggered manually or automatically. Differences associated therewith are described below in the context of a discussion of advantageous embodiments of the method.
- a message is sent to the control panel for each fire detector triggered during recording mode.
- a message is sent to the control center in that the control center receives a message from a fire detector or by generating a message in the control center.
- the control center does not differentiate between a message received from a remote detector or an internally generated message and processes every message that is sent to it in the same way.
- the processing of the message by the control center leads to a reaction from the control center to the message.
- a reaction is, for example, the output of a text and / or the activation of at least one output, the latter for example to activate an alarm device connected to the control center.
- the text output as a reaction can include a local text, such as "HEM 308 Liftlobby”, “427 WC Men”, “Copy room”, “New building photo-wood GG false ceiling » or a zone number, such as 41011/1 or 203/2.
- the period of time between the application of a stimulus and the reception of a reaction by the control center is usually in a range from 100 ms to 10 seconds, typically in the range from a few 100 ms to a few seconds.
- the reaction stored in the recording mode and the reaction resulting in the test mode are compared.
- the control center issues an error message if no match or insufficient match is found during the comparison.
- an error message is generated and output by the control center if no match or insufficient match is found during the comparison.
- the error message can be output directly to the control center and / or to a control center connected to the control center in terms of data or signals.
- the comparison is used to check whether the control center is still reacting in the same way at the point in time at which the test mode expires as it did at the point in time at which the recording mode was executed.
- the comparison can be used, for example, to check the function of the control center after a firmware update. A previously necessary corresponding test by an operator of the fire alarm system is no longer required and errors that can never be ruled out in such a test by an operator are now avoided.
- an actual activation of outputs is blocked during the execution of the method proposed here, that is to say in the recording mode and in the test mode.
- the reactions reaction recorded during the recording mode; reaction resulting during the test mode
- these inter- nen states are the contents of memory cells on the basis of which outputs are activated during normal operation.
- the method can also be developed by means of individual or several method features that relate to method steps carried out by a corresponding device, and the device can also be developed by means for carrying out method steps carried out within the scope of the method.
- the execution of the test mode after a firmware update can in principle be triggered manually, for example by an operator of the fire alarm system and by actuating a control element provided for this purpose. Additionally or alternatively it can be provided that the execution of the test mode is triggered automatically after a firmware update.
- a signal is triggered - in a manner known per se - for example from a software functionality monitoring the firmware update, which signal is evaluated for the automatic start of the test mode.
- a message sent to the control center and the response of the control center resulting in each case to the message are stored (both at the control center).
- the control panel is saved for each fire detector triggered during the recording mode with the cherten message is applied, ie the stored message is generated in the control center (loaded into a corresponding memory area), that is, whether it would have been received by an external alarm. This sends this message to the control center.
- the application of the message leads to processing of the message by the control center and a reaction by the control center to the message.
- control center processes the same message during the test mode as during the recording mode.
- comparing the respective resulting reactions (resultant and saved reaction during recording mode; resultant reaction during test mode)
- it is checked whether the control panel is still behaving in test mode as it did before during recording mode.
- each fire alarm triggered during the recording mode is automatically triggered in the test mode, namely by the control center.
- no stored messages are used during the test mode, but are generated again by the automatic triggering of the fire alarms.
- Each automatically triggered fire alarm sends a message to the control center when it is triggered. This means that the control center receives this message
- the message leads to the processing of the message by the control center as well as to a reaction of the control center to the message.
- the reaction resulting during the test mode is finally compared with the reaction recorded during the recording mode.
- reaction resulting and stored during the recording mode reaction resulting during the test mode
- reaction resulting during the test mode it is checked whether the center
- the control panel still behaves in the test mode as it did before during the recording mode. Due to the fact that the fire detector is also triggered in test mode, the test also includes the function of the fire detector and the transmission line.
- the comparison there of the reactions stored in the context of the recording mode with the reactions resulting in the test mode also includes a comparison of the reaction times recorded during the recording mode with the reaction times resulting during the test mode.
- the response time is the time between the sending of a message to the control center and the reaction of the control center to the message. In the event of a discrepancy or a discrepancy between the response times that exceeds a specified or specifiable threshold, an error message is issued.
- the recording mode and / or the test mode are carried out repeatedly according to a predefined or predefinable time schedule and / or after an event in the fire alarm system. This recurring execution is only possible for the recording mode as well as only for the test mode and for the recording mode on the one hand and for the test mode on the other hand. If only the recording mode is carried out repeatedly, this ensures that when the test mode is carried out (then for the first time), the most current data is available for the comparison made in the test mode. If only the test mode is carried out repeatedly, the comparison made within the scope of the test mode is carried out several times and any changes in the fire alarm system that occurred between two times of execution of the test mode can thus also be detected. If the recording mode and the test mode are carried out repeatedly, the advantages outlined above are combined. For the one taking place within the scope of the test mode In comparison, the data recorded in the context of the most recently executed recording mode are then used in each case.
- the method proposed here is preferably implemented in the form of a computer program for automatic execution.
- the computer program is an implementation of the objective method for operating a fire alarm system and for carrying out tests in the fire alarm system.
- the invention is thus on the one hand a computer program with program code instructions executable by a computer and on the other hand a storage medium with such a Compu terprogramm, so a computer program product with program code means, and finally also a device in de ren memory as a means for performing the method and its Refinements such a computer program is loaded or loadable.
- the invention is also a device which is intended and set up to carry out the method.
- the control center of the fire alarm system or a control center from a group of several control centers of the fire alarm system come into consideration as such a device.
- the respective device in particular the control center, comprises a processing unit in the form of or in the form of a microprocessor and a memory in which an implementation of the method in software is stored or in a manner known per se in order to carry out the method proposed here an implementation is stored or imprinted in software and firmware.
- the control center When the control center is in operation, it carries out the procedure, for example in which the recording mode is carried out when the system is started up for the first time and the test mode is carried out when the firmware is updated.
- FIG. 1 shows a fire alarm system with several fire alarms and a fire alarm center (control center),
- FIG. 2 shows the transmission of a message from a fire alarm to the control center in the event of the fire alarm being triggered, as well as an automatic triggering of a fire alarm by sending a stimulus to the fire alarm and the message sent on the basis of the stimulus,
- FIG. 3 shows a data structure (fire alarm list) that can be used in the context of the method proposed here,
- FIG. 5 shows a flowchart relating to a test mode carried out within the framework of the method proposed here
- FIG. 6 shows a schematically simplified representation of a computer program as an implementation of the method proposed here.
- FIG. 1 shows a fire alarm system 10 in a highly simplified schematic manner. This comprises, in a manner known per se, a plurality of fire alarms 12, at least one control center 14 and a transmission line 16 Devices (fire alarm 12, control center 14) are - in a manner also known per se - connected to the transmission line 16.
- the transmission line 16 is, for example, but not necessary, a ring line.
- the schematically simplified representation in FIG. 1 is also to be understood expressly only as an example with regard to the number of devices shown.
- Real fire alarm systems 10 include significantly more than the fire alarms 12 shown, for example twenty fire alarms 12, fifty fire alarms 12, one hundred fire alarms 12 or more, and / or exactly one control center 14 or more than one control center 14.
- the fire alarms 12 shown should in principle represent any number of fire alarms 12. Incidentally, the number of fire alarms 12 included in the fire alarm system 10 does not matter at all.
- the method proposed here is suitable for a fire alarm system 10 with a few fire alarms 12, for example a fire alarm system 10 with up to ten fire alarms 12, and for fire alarm systems 10 with up to one hundred fire alarms 12 and more.
- the number of control panels 14 included in the fire alarm system 10 is also irrelevant.
- the method proposed here is carried out by a device functioning as a control center 14 in the fire alarm system 10. Exactly one control center 14 comprised by the fire alarm system 10 is therefore sufficient.
- a fire alarm 12 When a fire alarm 12 is triggered, it sends a telegram (a data frame) to the control center 14 via the transmission line 16 and in a manner known per se, which is referred to as message 20 to distinguish it from other telegrams.
- message 20 This is shown in the presen- tation in FIG. 2 in a likewise greatly simplified schematic manner for a single fire alarm 12 as the origin of the message 20 and the control center 14 as the recipient of the message 20.
- reaction 22 a reaction 22 resulting from the processing (reaction of the control center 14 to the received message 20).
- a reaction 22 is shown only schematically greatly simplified.
- a reaction 22 comprises - also fundamentally
- At least one individual fire alarm 12 has so far been triggered manually. These then each send a message 20 to the control center 14 and the receipt of such a message 20 triggers the processing of the message 20 there and the response 22 to the message 20.
- An operator checks the reaction 22 of the control center 14, in particular the operator checks whether the reaction 22 matches the triggered fire alarm 12, for example whether a text that matches the triggered fire alarm 12 is displayed and / or whether it is for the triggered fire alarm 12 provided outputs (at least one output) are activated.
- the test includes - at least in special embodiments - a basically known automatic triggering of at least individual fire alarms 12.
- An automatic triggering causes a state on the part of the triggered fire alarm 12 as in the case of an alarm situation, for example as in the case of heavy smoke - and / or exposure to heat.
- Such an automatic triggering is initiated by the control center 14.
- the control center 14 sends a telegram called stimulus 24 to distinguish it from the message 20 via the transmission line 16.
- the stimulus 24 is received and processed by at least one fire detector 12 and upon receipt of the stimulus 24 the relevant fire detector 12 sends the message 20 already described above to the control center 14.
- This message 20 is also processed by the control center 14 and leads to a Response 22 of the control center 14 to the message 20.
- the stimulus 24 sent via the transmission line 16 for such an automatic triggering is also shown.
- the method proposed for the automated test comprises two modes or method sections, namely a recording mode 100 (FIG. 4) and a test mode 200 (FIG. 5).
- the recording mode 100 necessarily precedes the test mode 200 within the scope of the method. Accordingly, the recording mode 100 is also explained here first:
- predetermined or predeterminable fire alarms 12 of the fire alarm system 10 are triggered, namely triggered manually or automatically in the recording mode 100 and automatically triggered in the test mode 200 at least in a special embodiment of the method. If the fire alarm 12 is triggered automatically, this is done as described above. If the fire alarm 12 is triggered manually, this is done with means known in principle directly at the respective fire alarm 12, for example by means of a detector tester and / or by means of test gas.
- the manually triggered fire alarms 12 are the above-mentioned predetermined or specifiable fire alarms 12.
- the operator performing the manual triggering triggers for example, all of the fire alarms 12 included in the fire alarm system 10 or only individual fire alarms 12 .
- the operator triggers them for example, on the basis of the fire alarms belonging to a certain group (local, type or the like), on the basis of his experience or on the basis of a list available to him.
- the predetermined or predeterminable fire alarms 12 are here, for example, all of the fire alarm system 10 comprised fire alarms 12.
- the information about all fire alarms 12 comprised by the fire alarm system 10 is available to the control center 14 in the form of the configuration of the fire alarm system 10 and corresponding configuration data.
- the predefined or predeterminable fire detectors 12 are a group of fire detectors 12, namely a subset of the fire detectors 12 comprised as a whole by the fire detection system 10.
- This subset - or possibly also several different subsets - can or can be fixed (predefined ) and, for example, include all fire alarms 12 of a certain type or the fire alarms 12 comprised by the or a subset of each are selected (predefinable) by a person, for example an operator of the respective fire alarm system 10.
- FIG. 3 shows, in a schematically simplified form, a data structure, referred to below as fire alarm list 30, with a plurality of fire alarm data records 32, namely one fire alarm data record 32 for each fire alarm 12.
- the fire alarm list is created 30 due to the manual triggering of the fire alarms 12.
- the fire alarm list 30 is already the basis for the automatic triggering and results from the configuration data mentioned above.
- the type of fire alarm list 30 and the scope of a fire alarm data record 32 depend on a particular implementation of the method proposed here. The rest of the description refers, for example, to exactly one implementation option and the details explained are to be regarded as entirely optional in this respect.
- the fire alarm list 30 is implemented in the form of a list (data structure) and each fire alarm data record 32 comprises a fire alarm identifier 34, an optional flag 35, and a message section 36 and a reaction section 37.
- the fire alarm identification 34 is or comprises an address (bus address) or the like that uniquely identifies the fire alarm 12 on the transmission line 16.
- a position within the fire alarm list 30 is designated by means of a data item each referencing exactly one fire alarm data record 32, for example by means of a so-called pointer 38.
- the fire alarm list 30 is in the embodiment described the basis for a basically optional automatic activation of the fire alarms 12 in the recording mode 100 or an automatic activation of the fire alarm 12 in the recording mode 100 and in the context of the test mode 200. If the Fire alarm data sets 32 comprised by fire alarm list 30 each comprise a flag 35, it can be selected / specified by means of flag 35 whether or not the relevant fire alarm 12 is triggered as part of the automatic triggering. If the fire alarms 12 are to be triggered automatically and if all the fire alarms 12 included in the fire alarm system 10 are automatically triggered, a flag 35 (or an evaluation of such a flag 35) is unnecessary.
- One possible embodiment of the recording mode 100 is shown in the illustration in FIG. 4 in the form of a flow chart.
- the checked condition is of course not yet met and a branch is made to the corresponding sequence area (branch with the marking “(-)”, where “(-)” stands for the unfulfilled condition).
- the triggering 130 of a fire detector 12 takes place (either manually or automatically).
- a fire alarm data record 32 is created in the fire alarm list 30, ie due to the triggering 130, the control center 14 receives a message 20 from the triggered fire alarm 12 and based on the message 20, a new one, initially empty or initialized with start values Fire detector data record 32 generated.
- a corresponding date for example the bus address
- a corresponding date for example the bus address
- this takes place on the basis of a fire alarm data record 32 that already exists in the fire alarm list 30 (based on the configuration data), namely by sending a stimulus 24 to or for the fire alarm 12 identified in the respective fire alarm data record 32 by means of the fire alarm recognition 34 there.
- the triggered fire alarm 12 responds with a message 20 transmitted via the transmission line 16, which is received and processed by the control center 14.
- the message 20, optionally the message 20 and a time value for receiving the message 20, is or are recorded (at the control center 14). This takes place in the recording mode 100 within the framework of a message recording 140.
- the processing of the message 20 by the control center 14 triggers a reaction 22 to the message 20 after a certain time (control center reaction 150).
- the reaction 22, optionally the reaction 22 together with a time value for triggering the reaction 22 by the control center 14, is or are recorded (at the control center 14). This further recording takes place in the recording mode 100 in the context of a reaction recording 160.
- the algorithm then returns to the test 120 already mentioned at the beginning.
- the sequence described above (triggering 130 of a fire detector 12; receiving a message 20 from the respective released fire alarm 12; Generation of a response 22 to the receipt of the message 20 by the control center 14) is repeated.
- the fire alarms 12 are triggered manually 130, the next fire alarm 12 arises based on the operator's actions.
- the next fire alarm 12 results on the basis of the fire alarm list 30.
- the test 120 takes place on the basis of the fire alarm list 30. If the fire alarms 12 are triggered manually 130, the test 120 takes place on the basis of the configuration data (if all the fire alarms 12 included in the fire alarm system 10 have been triggered manually the condition evaluated in the context of the test 120 is met) or on the basis of an evaluation of an operation at the control center 14 (if the control action is used to signal to the control center 14 that no further fire alarms 12 are triggered manually, this is in the context of the test 120 evaluated condition fulfilled.
- test 120 leads to the result “all fire detectors 12 tested” or “all designated fire detectors 12 tested” (branch with the marking “(+)”, where “(+)” stands for the fulfilled condition), all are optionally Messages 20 received in the context of the recording mode 100 and the respective resulting reactions 22 are stored in pairs. At least the resulting reactions 22 are saves. In the embodiment shown, this storage 170 takes place at the end of the recording mode 100 and thus the recording mode 100 is ended ("E").
- successive storage while the recording mode 100 is running can also be considered. Then, for each message record 140 and each reaction record 160, the respective message 20 and the respective resulting reaction 22 (or the message 20 and a time value for receiving the message 20, in particular an absolute or relative reception time, as well as the reaction 22 and a time value to generate the reaction 22, in particular an absolute or relative reaction time) is stored immediately. This complete storage of all data is also optional. At least in the case of successive storage, the respective reaction 22 is stored for each reaction recording 160.
- the fire alarm list is used as the location for this saving (either saving 170 at the end of recording mode 100 or saving during recording mode 100 and as part of message recording 140 and reaction recording 160 or saving during recording mode 100 and as part of reaction recording 160) 30 into consideration, namely the message section 36 (for the received message 20, provided this is stored) and the reaction section 37 (for the resulting reaction 22) of the fire alarm data record 32 representing the respective fire alarm 12 there.
- reaction times are each stored in the form of reaction time data (reaction time date) in the reaction section 37, for example.
- the capture Such reaction times are achieved, for example, by starting a counter at the time of receipt and stopping the counter at the time of the reaction.
- the reaction time date comprises either a directly recorded reaction time or the basis for determining the reaction time, namely a time of receipt and a time of reaction in each case.
- the procedural section referred to here as recording mode 100 is carried out once, for example in connection with the commissioning of the fire alarm system 10, or repeatedly.
- an execution comes after an event in the fire alarm system 10, for example an exchange of at least one fire alarm 12 and a correspondingly resulting change in the configuration of the fire alarm system 10, or generally an execution after each change in the configuration of the fire alarm system 10 Consideration.
- a recurring execution according to a predefined or predefinable time schedule comes into consideration for a repeated execution.
- the recording mode 100 is repeated because of a configuration change, only those fire alarm data sets 32 that are affected by the configuration change are updated.
- test mode 200 (FIG. 5) is based on an at least one previous execution of the recording mode 100, because in the context of the test mode 200 previously recorded data in the recording mode 100 are used.
- test mode 200 is shown in the illustration in FIG. 5 - analogously to the corresponding illustration of the recording mode 100 in FIG. 4 - in the form of a flow chart.
- test mode 200 the fire alarm lists 30 and 30 that were created or used in the context of the recording mode 100 are used uses the data stored there. Also in test mode 200 - very similar to recording mode 100 - after the start ("S"), following an initialization 210, a test 220 (initial test 220) is carried out to determine whether all fire detectors 12 have been tested. This test 220 is carried out on the basis of the fire detectors derliste 30.
- a pointer 38 (due to the initialization 210) initially points to the first fire alarm data record 32 of the fire alarm list 30 and is pushed in the course of the test mode 200 based on the currently designated fire alarm data record 32 to the next fire alarm data record 32 of the fire alarm list 30
- Test 220 as to whether all fire alarms 12 have been tested can thus be carried out, for example and in a manner known per se, using the position of the pointer 38.
- the message generation 230 can include the automatic triggering of a fire alarm 12, namely the automatic triggering of that fire alarm 12 in accordance with the fire alarm data record 32 identified by the pointer 38.
- the automatically triggered fire alarm 12 then generates and sends the message 20 and the message 20 goes to the control center 14 on (the control center 14 receives the message 20), is processed there and triggers the respective reaction 22.
- the message generation 230 is also possible without triggering a fire alarm 12.
- the message stored in the recording mode 100 is then used as the message generation 230 20 (message section 36 of the respective fire alarm data set 32) in a kind of un This is generated in the manner that this is processed at the control center 14 like a message 20 sent out by a triggered fire alarm 12 (the control center 14 receives the message 20), so that a respective reaction 22 is also triggered to such a message 20.
- a reaction 22 of the center 14 results.
- This is then (reaction test 250) in relation is checked for the (reaction recording 160) reaction 22 recorded as part of the recording mode 100. It is therefore checked whether the reaction 22 recorded during the recording mode 100 (reaction section 37 of the respective fire alarm data record 32) corresponds or at least sufficiently corresponds to the reaction 22 resulting during the test mode 200.
- the reaction test 250 can also include a test of the respective messages 20, namely a comparison of the records recorded during the recording mode 100 for the triggering of the fire alarm 12 there Message 20 (message section 36 of the respective fire alarm data record 32) with the message 20 resulting from the triggering of fire alarm 12 there again during test mode 200. Such a test is also carried out for correspondence or at least sufficient agreement.
- the method branches to the initial test 220 (branch with the marking “(+)”). For this fire detector 12, the test is thus successfully completed If, however, no match or insufficient match was found in this reaction test 250, an error message 260 is issued (via the branch with the marking “(-)”) included display unit or assigned to the control center 14, and / or a log, for example in a memory included by the control center 14 and / or a memory connected to the control center 14 communicatively.
- the display and / or the log includes, for example, the respective fire alarm 12, the fire alarm identification 34 from the fire alarm list 30 and / or the reaction 22 recorded in the course of the recording mode 100 (from the reaction section 37 from the fire alarm list 30) and the reaction 22 resulting in the test mode 200 or parts of the recorded and resulting reaction Reaction 22.
- the method branches to the initial test 220.
- reaction times are also checked as part of the reaction test 250, namely by comparing those during the Recording mode 100 recorded reaction times and the resulting reaction times during test mode 200.
- an error message 260 is also issued.
- a counter can be started and stopped again with the triggering of the reaction 22 (reaction generation 240).
- the resulting tough The reading corresponds to the period of time required for the comparison.
- FIG. 6 finally shows, in a schematically simplified form, a computer program 300 as an example of an implementation of the method proposed here.
- the computer program 300 is loaded into a memory (not shown) of a device functioning as a control center 14 in a fire alarm system 10. This includes, in a manner known per se, a processing unit in the form of or in the form of a microprocessor (not shown) and the computer program 300 is executed by means of the processing unit when the control center 14 is operated.
- the computer program 300 comprises program code instructions with an implementation of the recording mode 100 as well as program code instructions with an implementation of the test mode 200.
- the recording mode 100 and the test mode 200 are started automatically by means of an activation routine 310 comprised by the computer program 300.
- the recording mode 100 is started, for example, on the basis of an operating action that can be detected by the activation routine 310.
- Such an operator action on the device for example pressing a button, is performed, for example, by an operator of the fire alarm system 10, for example when the start-up of the fire alarm system 10 is completed Firmware of the respective device (i.e. the center 14) has been updated (firmware update).
- the activation routine 310 automatically detects the completion of such an update or the activation routine 310 receives a corresponding signal in connection with the completion of such an update.
- the test mode 200 is optionally called up according to a schedule at predefined or predefinable times or can be started by an operator action - if the recording mode 100 has previously been executed at least once.
- the activation routine 310 checks corresponding call criteria, for example call times and / or call conditions.
- a method for automatically testing a fire alarm system 10 is specified.
- fire alarms 12 are triggered one after the other and the reactions 22 (recording mode reactions) of the control center 14 resulting from the triggering 130 are stored.
- the resulting reactions 22 (test mode reactions) during the test mode 200 are compared with the reactions 22 stored during the recording mode 100. In the event of discrepancies or insufficient agreement, an error message 260 is issued.
