Definitions
- the invention relates to a method and a device for controlling and monitoring an emergency or safety lighting system having at least one lamp connected to a central station and a monitoring and control module associated with the lamp.
- the object of the invention is to transmit such a status, which in particular corresponds to an inadmissible luminaire parameter, also to the central station.
- the periodic transmission of test and / or test queries and corresponding test and / or test responses between the central station and a monitoring and control module of the luminaire carried out, but also a substantially continuous monitoring of the luminaire with respect to at least one Luminaire parameters and generating a corresponding luminaire status, at least in the case of an impermissible luminaire parameter.
- the corresponding luminaire status is buffered.
- the status of the lights is then reported during the periodic transmission of the test and / or test responses from the monitoring and control module to the central station.
- the invention it is therefore possible to transmit a luminaire status which in particular corresponds to an impermissible luminaire parameter and which has been determined during continuous monitoring of the luminaire during the usual periodic tests in the corresponding time window to the central station.
- Such a luminaire status can correspond to different fault conditions of the luminaire, for example light bulbs not used, bulbs not functional, since at least one filament is broken, exceeding a limit value of the luminous flux or the like.
- the transmission of the corresponding test and / or test requests during a supply from the safety power supply is generally carried out.
- a safety power supply is a DC supply, although an AC supply can also be used as a safety power supply.
- the appropriate test and / or test queries are communicated to this backup power supply after switching from the utility power supply, this switching occurring for the duration of the corresponding test.
- corresponding data signals are modulated on the live conductors or the corresponding voltages or currents are changed to encode the data in a corresponding manner in amplitude, frequency or the like and possibly also by interruption in the current or voltage curve.
- the monitoring of the corresponding luminaire parameter can be carried out continuously during the luminaire operation, in particular in the case of mains power supply. This means that, except for the period of the corresponding test and operation by means of safety power supply, the corresponding luminaire parameter is continuously monitored throughout the operation of the luminaire. Of course, this monitoring can also be done during the test period.
- each individual luminaire can be specifically addressed and queried via an address assigned to it.
- a control signal is transmitted and / or switched off from the central station to the luminaire or also periodically Luminaire status updated.
- This also applies for example to a corresponding individual switchability of each luminaire via an address or the like.
- a switch-off information for the luminaire is transmitted by the central station.
- Each of these switching information then leads to a corresponding switch-off of the lamp, which is updated by this switch-off information or switching off a corresponding light status in the buffer. If the periodic or functional endurance test is to be carried out, not only is a corresponding test and / or test response transmitted from the luminaire to the central station, but also the updated luminaire status.
- a corresponding impermissible luminaire parameter and thus the corresponding luminaire status for example, it is possible to determine this via a current consumption of the luminaire and in particular of a ballast associated with the luminaire.
- the corresponding determination can be made in particular by the ballast upstream or integrated in the ballast monitoring and control module. It is also possible, in particular in the case of an electronic ballast, for the corresponding impermissible luminaire parameter to be determined from digital information of the luminaire or of the electronic ballast assigned to the luminaire.
- An impermissible luminaire parameter which is to be monitored in particular with fluorescent lamps, concerns the so-called end-of-life (EOL) phenomenon.
- EOL end-of-life
- damage has occurred due to local overheating of the lamp cap or lamp socket in the luminaire.
- Such damage can be caused by a variety of sources of error, but one possible process is the EOL phenomenon, which occurs in exceptional cases at the end of life of the lamp.
- One explanation for this EOL phenomenon is that the emitter material of the cathode is partially depleted or loses its emissivity for other reasons, making it difficult to emit electrons. This leads to an increased voltage drop at the cathode. Frequent cold starts can accelerate the loss of the active emitter.
- an EOL shutdown is required. This shutdown usually requires that, when the light source is active, its operating parameter for detecting the EOL phenomenon is continuously monitored and the light is switched off if corresponding shutdown criteria are met. It is obvious that the EOL phenomenon is not in a particular Time window occurs in which, for example, the corresponding test and / or test queries are transmitted from the central station to the light. Instead, the EOL phenomenon may also occur shortly after such transmission or at some point between two consecutive tests. In order nevertheless to transmit a luminaire status corresponding to the end-of-life phenomenon in the context of such a function or duration test, the corresponding luminaire status is temporarily stored and is only transmitted together with the test and / or test responses.
- test and / or test queries can be transmitted to a test and / or test queries, test and / or test responses and / or luminaire status, in particular by coding current or voltage pulses.
- This can be done, for example, the appropriate connection of the safety power supply, wherein in the given time window and also in dependence on each lamp one or more current pulses are generated on the supply line connection. These are then evaluated accordingly by the central station.
- the corresponding procedure can be carried out with DC safety power supply as well as with AC safety power supply.
- circuit switching or converter assemblies are used, which are used for communication with the connected lights and for current measurement in AC or DC operation and also query the light status.
- An apparatus has, for carrying out the corresponding method, an emergency lighting system having a central station and at least one luminaire connected to the same via at least one supply line connection, wherein the luminaire is assigned a monitoring and control module and wherein the device has a buffer for storing a luminaire status and between monitoring and control module and central station, if necessary, test and / or test queries and at least test and / or test answers are transferable.
- the monitoring and control module can be assigned in particular a ballast or electronic ballast of the lamp. The assignment may be that the monitoring and control module upstream of the ballast or integrated in this.
- the device may comprise a mains power supply and a safety power supply, wherein the safety power supply is formed for example by a central battery system or group battery system.
- the safety power supply is an AC power supply.
- this may have the temporary storage, so that for each lamp in the associated monitoring and control module, the corresponding lighting status is temporarily stored.
- the monitoring and control module may have a switching device. This can be designed for example as a relay, semiconductor switch or the like.
- the buffer may be a non-volatile memory.
- the monitoring and storage module may have a control and data processing device, for example in the form of a microprocessor.
- a be formed digital transmission device In order to be able to ensure transmission of the data to the monitoring and control module especially in an electronic ballast and digital data, between this and the other light, in particular the ballast, a be formed digital transmission device. This may possibly also be wireless.
- the monitoring and control module can have a data transmission device for coding / decoding and for receiving / transmitting data.
- the monitoring and control module can have a measuring device for measuring a current consumption of the luminaire or of the ballast.
- a measuring device may comprise a voltmeter, a shunt resistor and the control and data processing device of the monitoring and control module.
- the luminaire status can relate in particular to the EOL phenomenon, so that the luminaire is associated with a luminaire parameter detection device, in particular for detecting this EOL phenomenon and for switching off the luminaire.
- a luminaire parameter detecting means may perform, for example, an asymmetric pulse test, an asymmetrical power test, an open-loop test, or the like to detect the EOL phenomenon.
- the lamp of the luminaire can usually be a fluorescent lamp of T4, T5, T8 type or the like.
- a luminaire status and in particular the EOL phenomenon can be detected and logged during AC and / or DC operation, even if, for example, the corresponding EOL switch-off occurs at an undefined time in operation which does not occur in the time window of FIG Periodic test to be performed periodically during which the luminaire is supplied from the safety power supply.
- the emergency or safety lighting system according to the invention safer, since not only results of the prescribed tests and tests are taken into account, but at least another functional status of the corresponding lamp, see, for example, EOL phenomenon and EOL shutdown.
- FIG. 1 is a schematic diagram of an emergency or safety lighting system 1 shown. This comprises at least one central station 3 and a plurality thereof with at least one supply line connection 8 connected thereto lights 2. These are usually connected in parallel with corresponding lines of the supply line connection 8.
- the central station is connected to a mains power supply 5, not shown in FIG. 1 be supplied by the corresponding lights 2 in the control mode.
- the central station 3 may have a display device 17, for example in the form of a screen or the like, on which both data, states or the like of the central station 3 and each individual lamp 2 can be displayed. Furthermore, the central station may have keys, function displays, a connection for a data line connection 7, for example in the form of a data bus or the like. There is also the possibility of arranging a memory card reader or similar device.
- a safety power supply 6 is present, which is for example a central battery or group battery system.
- the safety power supply can also be an AC power supply.
- Each of the lights 2 has a fluorescent lamp (not shown) as a light source and a corresponding ballast 10.
- the ballast may be a magnetic or electronic ballast depending on the nature of the safety power supply.
- the electronic ballast is used in principle as a controlled DC or AC power source for the light source.
- the ballast influences the luminous flux due to frequency, waveform or amplitude. It serves to preheat the two lamp filaments, to ignite the lamp, to operate the lamp in a corresponding temperature interval, to switch off in the event of a fault and the like. At the end of the lamp life is usually a so-called end-of-life shutdown.
- the luminous means may be associated with a luminaire parameter detection device 16 for monitoring a corresponding parameter. This monitors, for example, the temperature of a coil and interrupts the power supply to the corresponding end-of-life shutdown.
- the luminaire 2 usually contains the corresponding ballast 10 or this is arranged at least in the vicinity of the luminaire 2. It is also possible that several bulbs are operated by a ballast.
- each lamp 2 is assigned a monitoring and control module 4, wherein this upstream of the corresponding ballast or integrated in the ballast.
- a monitoring and control module 4 At the two left in FIG. 1 arranged lights are preceded by a corresponding and in the two right in FIG. 1 arranged lights a corresponding integration of the monitoring and control module 4 relative to the ballast 10th
- the corresponding monitoring and control module 4 also has a nonvolatile buffer 9, which serves to store a corresponding luminaire status, resulting from continuous monitoring of the luminaire, at least during mains operation by mains power supply.
- the corresponding monitoring can also take place when supplied by the safety power supply 6.
- FIG. 1 a separate data line connection 7 is shown, by means of the test and / or test queries and corresponding responses between central station 3 and each monitoring control module 4 are interchangeable.
- the corresponding communication can also take place directly via the supply line connection 8, in which, for example, a coding takes place by means of one or more current pulses, a lack of a current pulse or a plurality of current pulses or the like.
- each lamp can be directly accessible, for example, via its assigned monitoring and control module 4, if the lamp is assigned a unique address. This allows, for example, a single switchability of the lights.
- the corresponding data connection between the central station and the luminaire is bidirectional, whereby a unidirectional communication is also conceivable. This can take place, for example, in that at certain given times each luminaire transmits corresponding data to the central station on its own without an initialization of the data request from the central station having to take place.
- the latter has a data transmission device 14. This is in FIG. 1 for simplification only shown with one light.
- the data transmission device 14 can also serve correspondingly for communication by means of the data line connection 7.
- corresponding information can also be available digitally and exchanged between the electronic ballast and the monitoring and control module 4 by means of the digital transmission connection 13.
- the digital transmission connection 13 can optionally serve to transmit a corresponding luminaire parameter, which defines a corresponding luminaire status.
- FIG. 2 an embodiment of a monitoring and control module 4 is enlarged and shown in detail.
- the corresponding power supply of lamp or ballast is carried out by the monitoring and control module 4, wherein the power supply is switched on and off, see switching device 11.
- switching device 11 may be in the form of a relay, a semiconductor switch or the like. If, for example, a switch-off information is transmitted from the central station to the luminaire, this is detected in the control and data processing device 12 of the associated monitoring and control module 4 and converted into a corresponding switching command, by means of which the switching device 11 is set to the switch-off state.
- the corresponding switch-off information is used in an embodiment of the invention in addition to initiate a query by means of the monitoring and control module 4 to determine whether a power consumption or a corresponding digital information of the ballast signals a fault status of the lamp.
- This fault or luminaire status is then stored in the nonvolatile memory 9 of the monitoring and control module 4.
- the corresponding current consumption of the ballast can be detected, for example, by means of the measuring device 15 of the monitoring and control module 4.
- the measuring device 15 includes, for example, a voltage measuring device or a threshold value switch 19 and a shunt resistor 20.
- the nonvolatile memory is integrated in the control and data processing device 12.
- a logical linkage of the luminaire status with corresponding test and / or test responses continues to be carried out in order to transmit a positive message to the central station in both cases in the event of no error. If there is an error, that is, at least in the luminaire status or the test and / or test responses, the error is signaled to the central station.
- the central station may continue to have circuit switching or converter assemblies that enable the corresponding power supply from the backup power supply, with the appropriate functional or operational endurance tests occurring after the backup power supply is applied.
- the corresponding luminaire status is only interrogated during operation by the safety power supply 6, while, however, it is continuously detected during operation by the mains power supply 5. As a result, costs can be avoided, which would otherwise also result in interrogation of the luminaire status during operation with mains power supply.
- the system is simpler, since the transmission of the light status preferably takes place only during the corresponding functional or durability test during operation by the safety power supply.
- the luminaire status is continuously monitored. An update of the luminaire status occurs at least upon transmission of each switch-off information to the luminaire and / or periodically, see the above statements.
- Such updated luminaire status is correspondingly stored in the nonvolatile memory and linked to a corresponding test response during the periodic or functional duration test to be performed on a regular basis.
