Definitions

  • the invention relates to a device for controlling and managing lamp functioning state, comprising a microprocessor unit and a waveguide transmission system.
  • the present invention adopts the above technology as well as other parameters (which will be better explained hereinbelow) in order to obviate the above-described drawbacks in the pior art and provide a control and management device for lamp circuits, which integrates all of the circuitry relative to the control functions of the lamps, in which the said circuitry is entirely microprocessoried both centrally and peripherally with the aim of lowering realization costs and rendering the management of the system more precise, more direct and easier to operate.
  • the three squares evidenced by broken lines refer to the following: 1 denotes the part of the block diagram relating to the circuitry of the waveguide device transmitter; 2 the part of the diagram relating to the waveguide transreceiver interface; and 3 a block diagram relating to the device receiver.
  • the transmitter circuitry 1, 2 denotes the waveguide transreceiver interface, more completely illustrated in square 2, while 3 (also represented in an independent square) denotes a single-chip microprocessor managing the transmitter unit.
  • the microprocessor is provided with an EEPROM permanent memory 4 memorizing transmitter parameters and code.
  • the permanent memory 4 memorizes the identifying number of the transmitter, assigning it a code of from 1 to 128, as well as the transmitter functional parameters, that is, the various timings, the threshold values of the phase displacement angle, the number of lamps, and so on.
  • the transmitter can be identified through its code, the lamp it is associated to (with its various parameters) can also be identified.
  • the parameters can be modified to adapt the transmitter to the various kinds of lamps and diverse transmitter application conditions.
  • the voltage zero is read by a sensor block 5 constituted by a logic gate comparator which compares the actual voltage with zero voltage and further checks that the voltage does not fall below a certain minimum value.
  • a circuit block 6 effects a circuit check of the current zero, verifying when that occurs and also ensuring that the current does not fall below a predetermined minimum threshold and cause the microprocessor 3 to signal a halt to the lamp supply circuit.
  • Said circuit block 6 is constituted by a logic gate comparator which compares the current value with a zero value.
  • Block 7 denotes an electronic switch consisting of a piloted transistor serving to control the on/off operations of the lamp, which the device of the invention is connected to through connection 7a.
  • the waveguide transceiver interface 2 With regard to the waveguide transceiver interface 2, it can be seen how the 220 volt supply is used through a network connection circuit 9 constituted by a circuit section consisting of transistors and a coil.
  • Downstream of the network connection circuit 9 is a corresponding transmitter-receiver circuit 10, constituted by a circuit filter 11.
  • a tone-decoding circuit 12 Downstream of the transmitter-receiver circuit 10 is situated a tone-decoding circuit 12, which by means of a PLL circuit intercepts a signal of a certain frequency in the envisaged period and takes on the assigned value.
  • the uncoded signal leaving the decoder 12 is then sent, through line 10a, to the local microprocessor 13 of the microprocessor 3 set on the lamp which is to be checked.
  • Figure 2 shows the different possible functioning conditions of a lamp 19, subdivided into 2a, 2b, 2c and 2d according to the state of the lamp.
  • FIG. 2a shows normal functioning situation, wherein the lamp is supplied through clamps 21a and 21b; a rephasing condensor 20 being provided, as well as a traditional-type reactor 17 and an ignition device for fluorescent lamps, denoted by 18.
  • the lamps described and illustrated are mercury or sodium vapour lamps 19.
  • the difference between the two types of lamp consists in the fact that for sodium vapour lamps no ignition system is present.
  • 2c illustrates a classic situation in which the lamp 19 is in short circuit, as the clamps 19a and 19b are directly connected one to another.
  • 2d illustrates a lamp 19, switched off due to a defective ignition 18.
  • the device uses the waveguide system; that is, a system in which a signal is transmitted in frequency by a transmitter, travelling on a normal electrical line, and which is received by a receiver when the network is enabled, and hooked up to the functioning frequency decided on during its design.
  • the waveguide system that is, a system in which a signal is transmitted in frequency by a transmitter, travelling on a normal electrical line, and which is received by a receiver when the network is enabled, and hooked up to the functioning frequency decided on during its design.
  • the waveguide system that is, a system in which a signal is transmitted in frequency by a transmitter, travelling on a normal electrical line, and which is received by a receiver when the network is enabled, and hooked up to the functioning frequency decided on during its design.
  • a frequency signal on the grid electric supply, which in Italy is of 50Hz.
  • the receiver couples into the network, hooks the signal, decodes and interprets it.
  • the device using the waveguide system, can not only check the lamps, but also manage them singly, as it reads the phase angle between voltage and current.
  • phase angle between the current and voltage is independent of the type and power of the lamp and thus cannot place constraints or limitations and is not therefore influenced by a variation in the supply voltage, while it is very characteristic of the state of the lamp.
  • This phase angle is determined by measuring the time interval between the passage through zero of the voltage, that is the negative-positive transition, and the current passage through zero, that is the always-negative-positive transition.
  • the period corresponds to about 20ms, equivalent to 360 degrees.
  • phase angle In relation to situation 2a, in normal lamp conditions the phase angle must oscillate between 20 degrees and 25 degrees.
  • the angle to be read In relation to situation 2b, where the rephasing condensor 20 is broken, the angle to be read must oscillate between 50 degrees and 75 degrees.
  • the sensing is done by means of comparators 5 and 6, which send the signal to the processor 3 which processes the corresponding situation in order to determine the angle range and to see what situation the lamp 19 is in, according to the memory.
  • each transmitter 1 is identifiable by a code going from 1 to 128, and a specific easily-interpretable communication protocol is proevided between the central unit, which can be situated at distance from the lamp series line and the single processors 3 and 13 present on each lamp-post.
  • the protocol is such that the first byte identifies the transmitter while the second byte serves to command the switch 7 to turn the lamp on or off, or group of lamps, in the case of transmitters controlling more than one lamp.
  • the first byte identifies the transmitter 1 code and the second byte indicates the lamp situation.
  • the maximum possible number of lamps is 128, that being the maximum number of transmitters installable. As each transmitter controls more than one lamp, more than 128 lamps can be controlled and managed.
  • the remote central unit calls the single transmitters, which, having received the signal on its receiver 2, send their own identification code and the state of their own lamp back. It is possible then to activate or deactivate each lamp centrally, simply by using the on/off switch 7.
  • the 112 KHz transmitter is present in the transceiver 2 circuit interface of the transmitter 10 and is commanded by the microcontroller, which is in effect the on/off switch 1 and 2.
  • the filter 11 frequency-filters such signals and decode them through a tone-decoding operation performed by the decoding circuit 12.
  • the microprocessor 3 and the microprocessor 13 permit of interfacing between the various modules 1, 2 and 3, actuate the decoding of the received waveguide signals, being provided with resident firmware, and participate, together with the comparators 5 and 6, in verifying that the lamp supply voltage is present and is not below a predetermined value, in order to gurantee and optimal management of the communication and modulation of the waveguide transmission carrier.
  • the voltage-current phase angle signal of each lamp is sent, and according to the measurement of the angle, a lamp state situation is established and an actuation command is transmitted.
