Definitions

  • the present invention relates to an integrated system for the diagnosis and handling of fluorescent lamps.
  • Central boards are currently known for the handling of a series of lighting lamps according to a standard communication protocol ("DALI" protocol), which allows the local and/or centralized diagnosis of lamps, and there are still specific central boards for the supervision and diagnosis of emergency lighting lamps.
  • DIALI standard communication protocol
  • the designing of the new system derives from the intention of providing an innovative mixed emergency lighting system, with illuminating appliances (ballasts), which share the same communication bus with the emergency devices and are subject to the same central control board, also for the purpose of facilitating installation and maintenance operations.
  • an objective of the present invention is therefore to provide an integrated system for the diagnosis and handling of fluorescent lamps, which allows a single product to be used, suitable for effecting a local and/or centralized diagnosis of lighting lamps and emergency lamps.
  • Another objective of the present invention is to provide an integrated system for the diagnosis and handling of fluorescent lamps which facilitates the installation and maintenance operations of the lighting and/or emergency plants.
  • a further objective of the invention is to indicate an integrated system for the diagnosis and handling of fluorescent lamps, which is particularly reliable and is easy and economical to produce, without the use of complex or costly technologies, and which allows a precise, rapid and economical installation of lighting and/or emergency plants.
  • the mixed emergency lighting system advantageously uses lighting appliances (ballasts) which share the same communication bus with the emergency devices and are subject to the same central control body, with the additional purpose of facilitating installation and maintenance operations.
  • the lamps used in the system provide an intelligent handling of their functioning, both in an autonomous and centralized manner.
  • the devices forming the system are both electrically and mechanically easy to install and set up, thanks to self-programming functions, contained in the central board, simplified for the installer and oriented towards the type, and above all use, of plant which is created (such as scholastic, hospital, office, projection room installations, etc.).
  • 1 indicates a communication interface towards which a series of inlet commands are directed, connected, by means of a serial line 2, to a diagnosis and supervision board 3 which is, in turn, connected, by means of a serial connection, to a first series of lighting lamps, indicated with 4, to a second series of emergency lamps 5 and to one or more intelligent pushbuttons 6.
  • the board 3 allows the whole lighting and emergency plant to be handled and, in particular, set up, without the necessity of using a Personal Computer, but only using a keyboard and display, assembled on the board 3.
  • the board 3 also provides an intuitive and descriptive user interface, which remains enclosed with the plant also after its installation; a more sophisticated instrument than the board 3 is not necessary for the full configuration of the plant.
  • the integrated system thus provides for the handling of a mixed lighting and emergency plant, wherein each device 4, 5, 6 can be remote controlled by the same board 3.
  • the board 3 englobes the functions of two boards: one for controlling the lighting lamps and one for controlling the emergency lamps.
  • each lighting lamp 4 or emergency lamp 5 is created as an autonomous device, with automatisms which allow it to periodically effect automatic tests and provide visual information of their results.
  • the same appliance can also be incorporated into a centralized plant, wherein the central unit takes over its control, substituting its automatisms (test temporizations) with those of the unit; analogously, if the lamp is abandoned by the central unit (due to the removal of the central unit itself, or in any case as a result of a prolonged interruption of the communication) and it consequently no longer receives remote-controlled orders, it will continue its own activity autonomously, without any problems or reductions in its functionality and therefore effecting the periodical tests for which it has been set up.
  • the central unit takes over its control, substituting its automatisms (test temporizations) with those of the unit; analogously, if the lamp is abandoned by the central unit (due to the removal of the central unit itself, or in any case as a result of a prolonged interruption of the communication) and it consequently no longer receives remote-controlled orders, it will continue its own activity autonomously, without any problems or reductions in its functionality and therefore effecting the periodical tests for which it has been set up.
  • the lamps 4, 5 effect their own operations in a totally autonomous manner, and the central unit 3 sends its own orders by writing the data directly in the memory of the lamps themselves: in this way, the lamp 4, 5 does not have to waste time in decoding the orders, or verifying its own state prior to the orders themselves (in order to effect them or not), but must simply continuously realign its functioning with the state imposed by the data contained in its memory.
  • Action Register containing 8 bits which determine the future functioning of the device: by modifying one of these bits, the lamp immediately triggers the realignment operations of its own functioning without any sign as to by who or when said bit was modified; during normal functioning, these bits are modified by the lamps itself, for example upon reaching a certain meter count.
  • the control and supervision board 3 can also communicate with the lamps 4, 5 in an emergency, by feeding the serial bus 7 for the communication, thanks to its own accumulators; by driving the bus 7 only during the brief period of the communication, a considerable energy saving is obtained which maximizes its autonomy.
  • the control board 3 can also handle lighting and emergency plants with a rescue group; in this case, when there is central power supply, each lamp 4, 5 is handled with simple lighting, whereas, when there is no central power supply to the rescue group, the control board 3 detects this and brings all the lamps 4, 5 to the respective emergency light (pre-set by the installer), and they are maintained in this state until the expiry of the respective icos.
  • the lamps 4, 5 regulated for maximum autonomy remain switched on until the charge of the rescue group becomes exhausted.
  • the whole plant is therefore fed until the charge of the rescue group has been exhausted so that the lamps 4, 5 can in any case be manually controlled by switching them on and off or modifying their light.
  • figure 2 shows a block scheme of the hardware present in the diagnosis and supervision board 3, which comprises an AC/DC 8 switching feeder, a feeder 9, a battery 10, a battery-charger 11, a booster 12, a microprocessor 13, suitable for exchanging data and commands with the user inlet/outlet interface 14, with a count meter or timer 15 and with a serial line 16, of the RS485 type, which forms the connection to the communication bus 17 of the various control and supervision boards 3, or to the serial line 2 connecting with the communication interface 1.
  • the diagnosis and supervision board 3 which comprises an AC/DC 8 switching feeder, a feeder 9, a battery 10, a battery-charger 11, a booster 12, a microprocessor 13, suitable for exchanging data and commands with the user inlet/outlet interface 14, with a count meter or timer 15 and with a serial line 16, of the RS485 type, which forms the connection to the communication bus 17 of the various control and supervision boards 3, or to the serial line 2 connecting with the communication interface 1.
  • a receiver/transmitter interface 18 of the control board 3 is connected to the communication bus 7 of the lamps 4, 5.
  • control and supervision board 3 is illustrated in the equivalent electronic circuits according to figures 13-17.
  • control board 3 suitable for running a lighting plant with a standard DALI communication protocol also in the absence of central power supply, as it is autonomously fed by a series of rechargeable accumulators 10, consists of a central power supply AL step, the battery-charger 11, the series of rechargeable accumulators 10, the DC/DC booster 12, a control organ CC, which comprises the microprocessor 13 and which handles the functioning of the whole equipment, and a transmitter/receiver step 18 for communication with the serial bus 7 of the plant of lamps 4, 5.
  • figures 14 and 15 enclosed respectively illustrate the energy circulation and control logic of the control board 3.
  • the AL feeder supplies energy to the control organ CC, the battery-charger 11 and transmission/reception block 18; the transmission/reception block 18 is constantly tuned in to the plant bus 7, and the control logic or organ CC, comprising the microprocessor 13, activates its supervision.
  • the battery-charger block 11 regulates the necessary current for recharging the battery accumulators 10, under the control/command of the control organ CC, until a full charge is reached; from this moment, the battery-charger 11 supplies the battery accumulators 10 with the charge maintenance current.
  • the DC/DC booster 12 is switched off, as the feeding AL already supplies a sufficient voltage to the transmission/reception block 18, which polarizes the plant bus 7 (figure 16).
  • the internal feeding is taken from the battery 10 and a precise sensor positioned in the feeder AL communicates to the control organ CC in real time, the presence or absence of the external supply (figure 15).
  • control organ CC turns on the booster 12 exploiting the energy of the battery 10 and continues the handling of the plant bus 7, by controlling the transmission/reception block 18, as in the presence of the central power supply (figure 17).
  • the bus 7 can be kept continuously active for the whole time allowed by the capacity of the battery accumulators 10 or, a more intelligent solution, the communication can be activated only for the sending of messages to the plant on the part of the control body 3, so as to exploit to the utmost the charge stored in the accumulators, as it is used only and when strictly necessary.
  • FIG 3 shows a block scheme of the hardware of each lamp 4, 5, which comprises a transformer 20 of the central power voltage, a battery-charger 21, a battery 22, an oscillator 23, a central power sensor 24, a battery sensor 25, a feeder 26, a control microprocessor 27, a sensor of the fluorescent tube 31 of each lamp 4, 5 and a series of communication interfaces 29, 30 with the user and with the connection bus 7 of the lamps 4, 5.
  • the oscillator 23 allows the tube 31 to be turned on at various light levels (and, consequently, supply absorption), in relation to the frequency and duty-cycle of a digital PWM signal.
  • the circuit which generates this signal contains the various combinations necessary for obtaining the desired light power in relation to the voltage supplied by the feeding 33 (which can be the battery 22 or other means).
  • FIGS 4-12 illustrate in more detail the high frequency electronic piloting circuit of the fluorescent tube 31 of each lamp 4, 5.
  • the circuit comprises the two-coil voltage raiser transformer 32, a power switch Q1 and the relative pilot circuit DR, a series condenser C1, which supplies the electric current to the tube 31, a preheating condenser C2, which supplies the preheating current to a cathode of the tube 31, the tube current sensor 28, and a control element CL, comprising the microprocessor 27, which controls the commutation of the power switch device Q1 in relation to the current indicated on the tube 31 by the sensor 28; the whole equipment is fed by the DC feeder 33 (figure 4).
  • the circuit must activate the preheating of the cathodes RC without lighting up the tube 31, which occurs after exceeding a certain voltage between its cathodes.
  • the circuit is piloted by the controller CL, by means of a periodical rectangular signal, with the following procedure:
  • the general effect is to send current to the cathode RC both during the T ON(1) period and also during the T OFF(1) period without causing a premature lighting of the fluorescent tube 31, and thus keeping the mesh comprising the tube 31 itself, negligible, as considered above.
  • the preheating phase lasts for a reasonably sufficient time for preheating the cathode RC, considering as optimum preheating, a value which reaches the cathode RC resistance, approximately quadruple with respect to the value measured before heating.
  • the controller CL modifies the frequency and duty-cycle of the periodical rectangular signal which commands the driver DR, in order to provoke the lighting of the tube 31.
  • T ON and T OFF times are lengthened and, in this phase, we will call them T ON(2) and T OFF(2) .
  • T ON(2) is much greater than T ON(1) , we can say that the quantity of energy which is stored in the magnetic nucleus of the transformer 32 is much higher than the first phase (preheating).
  • the lighting of the tube 31 consists in a substantial lowering of its impedance series, which makes the mesh to which the tube 31 itself belongs, no longer negligible; this mesh has not been considered so far due to the negligible current it received, but with the lowering of the impedance of the tube 31 this current becomes significant for the analysis of the circuit.
  • the tube 31 maintains lighting even if the voltage at its cathodes drops below its nominal lighting voltage; we can therefore assert that, also during T ON(2) , the current can circulate through the tube 31; it should be remembered that in the preheating phase, the voltage during T ON(1) was not sufficient for lighting it, but now the tube 31 has already been lit thanks to the overvoltage of T OFF(2) .
  • the primary current which relates to the primary circuit T1p, is functionally composed of two parts: one part is destined for the magnetization of the nucleus of the transformer 32, whereas the other part is brought back to the secondary circuit with the classical transfer procedure of transformers.
  • the storage current has an increasing linear trend during the whole of T ON(2) , whereas the component transferred to the secondary circuit has an exponentially decreasing trend according to the time constant between the condenser series C1 and the lit tube 31; this constant is dimensionally several times the duration of T ON(2) (figure 9).
  • the energy stored in the previous T ON(2) is responsible for a primary and a secondary overvoltage, which generate two currents: the primary current flows in the preheating circuit completely recharging C2 up to the feeding voltage of the feeder 33, whereas the secondary current flows through C1 (tending to recharge it) and the tube 31.
  • this circuit preheats a single cathode, the cathode RC.
  • the tube current sensor 28 consists of two diodes, D1 and D2, a current reading resistance R SHUNT having a negligible value with respect to the equivalent impedance of the lit tube 31, a resistance R1 and a measuring condenser/filter C3 (figure 10).
  • the current sensor 28 is structured for only "reading" the current flowing in the tube during T ON ; it reproduces on the condenser C3 a voltage proportional to the average value of the current which flowed during T ON relating to the whole period.
  • the current flows through the diode D1 and contributes with a null value to the average value measured.
  • the average current of T ON is proportional according to the coil ratio to the current supplied by the feeder 33 and consequently, if the duration of T ON and the value indicated at the primary circuit of the inductance of the transformer 32 are known, and by measuring the feeding voltage of the feeder 33, it is possible to calculate with very good approximation the current supplied by the feeder responsible for the energy stored in the magnetic nucleus during T ON .
  • the presence of the diode D1 guarantees a reduced power dissipation.
  • the circuit driver for the switch Q1 consists of a condenser series C4, a resistance series R2, a protection diode D3 and a switching off resistance R3 (figure 11).
  • a MOSFET transistor was considered as Q1 in order to maintain a high performance; analogously, it is possible to use a BJT transistor, but in this case it is necessary to amplify in the current, the command signal sent by the controller CL, to be able to guarantee adequate currents on the collector of the transistor.
  • this block is to transmit switch-on and switch-off commands to the switch Q1; in particular, the condenser series C4 prevents a continuous high level coming from the controller CL from keeping the transistor running for excessive times which could cause its destruction.
  • the time constant between the condenser C4 and the sum of R2 and R3 is, in fact, in any case lower than the time sufficient for the transistor to become damaged.
  • the resistances R2, R3 and the condenser C4 take to the MOSFET gate Q1 the necessary part of voltage for effecting its activation, whereas the resistance R3 has the function of discharging the MOSFET gate Q1 if the command coming from the controller CL remains fixed at a high level.
  • the diode D3 protects the transistor gate from inverse voltage, coming from the shunt C4 and is also responsible for the rapid discharging of the voltage memorized on the condenser series C4 within the time T OFF , (figure 12 shows a complete piloting circuit scheme).
  • the control logic CL must itself control the switch Q1 and its function is to regulate the power requested at the outlet of the fluorescent tube, regardless of the feeding voltage of the feeder 33 available, and variation in the characteristics of the tube 31 as a result of its aging or temperature variation.
  • This potentiality can be exploited in order to keep the luminosity at the outlet constant, or to effect controlled variations in the luminosity over a certain period of time.
  • the control logic CL does in fact contain an algorithm which processes the information available; this information is:
  • the algorithm gives, as a result, the length of the subsequent T ON and T OFF , which characterize the rectangular command sent to the pilot circuit DR, and from there to the switch Q1.
  • the handling of the light in real time allows the trend of the light emitted in relation to the time to be established, to help, for example, the pupil of the human eye to adapt itself to the change in luminosity.
  • a circuit with this potentiality can immediately provide a luminosity comparable with that of the lighting prior to a black-out, gradually decreasing it as the eye becomes accustomed to the less intense luminosity (also maximizing the autonomy of the accumulators).
  • a further advantageous characteristic of the system is due to the fact that it has a functioning of the Rest-Mode type, i.e. that it automatically adjusts itself to the implementation of the emergency which has just been fed.
  • This automatic lighting up does not take place during maintenance: with the circuit without feeding, in fact, when the operator has to substitute the battery, when connecting the new battery, the device is not automatically lit up, preventing dangerous currents or voltages from circulating in areas accessible to the maintenance operator.
  • the system effects the tube 31 test of each lamp 4, 5 during its lighting from the central power supply and provides an immediate error signaling upon breakage of the tube 31, also in a normal electric power supply lighting.
  • the microprocessor 27 of each lamp 4, 5 enters materially and closely the functioning of the various sections and is not limited to controlling their functioning, so that the lighting lamp and emergency lamp entirely depend on it.
  • the microprocessor 27 is therefore an integral part of the feedback rings of the various regulators and, in particular, with respect to the functions of the battery-chargers 21 and oscillator 23, said functioning can be attributed to various complex algorithms which provide, in relation to the sensors available, double frequency/duty-cycle information which is sent to the final transistors.
  • each lamp 4, 5 has a fixed identification number; if this number is even, the appliance (when it is not remote-controlled by the control board 3) establishes its own count meters for effecting the periodical tests at the moment established by the user (by means of a synchronization procedure), whereas if it is an odd number, it establishes them for effecting the tests with a week's delay.
  • the arrangement can also be inverted by means of a remote-control element (control board 3 or remote-control); this remote-controlled set up is not definitive, as each lamp 4, 5, in the absence of further orders, returns, after a certain period of time, to the original set up, as regulations prohibit having a plant totally synchronized on the same time schedules.
  • a remote-control element control board 3 or remote-control
  • each appliance which has reached the minimum battery maintains its own count meters active for a further 24 hours, so as not to lose the synchronization with the other appliances of the plant.
  • Each device is set up to zero (synchronize) its own count meters in relation to a certain absence and return sequence of the power supply. It is therefore possible to establish when the following automatic tests should be effected by manually applying with the energy switch, a definite switch-on and switch-off sequence: the system guides the operator for effecting this sequence (whose temporization is fundamental) by the precise flashing of its own LED signaling diode.
  • the operator can effect the synchronization of the whole plant without the necessity of adopting a remote-control device or any other remote-controlled unit.
  • the system can also guarantee autonomy with greater light in the first minutes of an emergency, which is much higher than the minimum required by law, subsequently terminating the autonomy until the exhaustion of the charge of the accumulators and supplying the minimum luminosity guaranteed.
  • the system uses the same electric communication bus described in the standard DALI specifications; the communication protocol used is therefore put in communication with proprietary frames which should in no case be confused with the official DALI frames.
  • this consists of 17 bits (commands) or 9 bits (responses), transmitted with a Manchester coding, i.e. each bit consists of two inverted half-bits, which acquire the meaning together (two half-bits 01 mean a 1 logic, two half-bits 10 mean a 0 logic); this datum frame is followed by two stop bits which do not have inversion between the first and second half-bit, and are at a high logic level (basically they are four half-bits at 1).
  • DALI frames consist of from 19 to 11 bits, codified as described and each frame which does not have a datum bit with the Manchester inversion or does not have the two stop bits fixed at 1, is discarded.
  • the communication protocol frames used in the system according to the invention have two stop bits fixed at zero (four half-bits at 0): this coding can in no way cause confusion between these frames or parts thereof and correct DALI frames.
  • the frames of the system according to the invention which are longer than the DALI frames have (for the DALI receivers) Manchester inverted stop bits, whereas the frames which are shorter than the DALI frames have (for the DALI receivers) at least one Manchester non-inverted datum bit; in both cases, the DALI receivers reject the frames of the present invention.
  • a receiver after discarding the first part of the frame, a receiver can start receiving the final part of the same transmission as a second transmission, but for the same reasons described above, this will also be discarded.
  • a situation of this kind leads to a definite communication failure as, even if the timings are more or less superimposed, there will be conflict at the moment in which the two entities transmit a different bit from each other and, in the best of cases, the response will be discarded (and therefore lost).
  • the system according to the invention also effects a verification of the state of the bus 7 during the response, before the transmission of each half-bit, with particular attention to those at 1 (which correspond to the free state of the bus).
  • the system allows a more efficient dispute of the communication bus 7, thus reducing cases of discarded responses due to conflicts between various transmitting lamps, as the first lamp which realizes that it is under dispute will withdraw without "fouling" the datum transmitted by the other lamp.
  • This method forms an extra safety means for effecting certain commands which relate to delicate parts of the functioning of a lamp, or in which it is important for only one entity to be active.
