Definitions
- the present invention relates to the technical field regarding the management of a lighting plant, with particular reference to management by radio-frequency networks.
- loads are preferably connected with one another in series, so as to define a so-called load mesh.
- Electric loads can be connected in series with the aid of corresponding coupling transformers having the corresponding primary coil in series, in this case, to the same load mesh.
- electric cables can be replaced by optical fibres which, however, imply high costs and problems relating to the connection reliability in case of water and dirt.
- a further solution consists in using waves conveyed onto the load mesh cables; however, this is very difficult to implement due to the presence of the coupling transformer inductance.
- An object of the present invention is to propose a system for managing a lighting plant, wherein the local circuitry is managed by radio-frequency networks, which should ensure a high reliability and allow optimum operation of the same both as regards the activation and/or deactivation of each load, and as regards the ON/OFF operating status and integrity check.
- Another object of the present invention is to minimise electric circuitry of the control network managing said lighting plant, allowing at the same time easy extensions of the same system without affecting its functionality and versatility.
- a further object of the invention is to propose a technical solution of simple design, relatively little cost, capable of controlling the characteristic parameters of the loads and of integrating with pre-existing management and control systems, allowing a considerable extension of the same.
- reference A is used to denote the area on which a lighting plant extends, essentially consisting of a plurality of n groups of m loads each (L11, ..., Llm), ..., (Ln1, ..., Lnm) determining respective elementary areas A1, ..., An on which the same groups of loads are properly distributed ( Figure 1).
- Such lighting plant basically consisting of lamps, for example connected in series to define forced current circuits, is powered and managed by an earth control network, of type known in the field, capable of feeding each load Lji.
- Such control network allows activating and/or deactivating at any time each load (Lj1, ..., Ljm) of the generic j- th group using control members (not shown) of known type, as well as checking their ON/OFF operating status and optionally testing their circuit integrity by proper tests.
- each load Lji comprises a relevant circuit group (not shown for clarity) provided with the local circuitry, of known type, needed to enable and/or disable the same, to check the above operating status and the circuit integrity of the same.
- each load Lji can interact through radio-frequencies both with the co-ordination control unit W and, optionally, with a support control unit Wj provided in the proximity of the area Aj to which the same load Lji belongs.
- each load Lji is capable of communicating by means of radio signals its ON/OFF status and its circuit integrity to the co-ordination W and support Wj control units, obtained using its circuit group.
- each load Lji for example embedded in the layer of insulating resin of the same load Lji
- such microprocessor device manages and controls the above circuit group, associated to each load Lji, comprising the local circuitry that enables and/or disables it, and checks the operating status and the circuit integrity of the same.
- the proposed managing system is particularly useful in public lighting plants and the systems for lighting the airports, where the areas A are very large and the maintenance service must be rapid and preferably limited to indispensable interventions.
- a particularly appreciated and useful advantage results from the possibility to manage a lighting plant which can be extended and/or modernized without interrupting the service or changing in any way the working and versatility thereof.
- the proposed system for managing a lighting plant by radio-frequency networks ensures a high reliability and allows optimum operation of the same both as regards the activation and/or deactivation of each load and as regards the ON/OFF operating status and integrity check.
