DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a control system for several appliances in distributed arrangement, in particular lighting fittings in one or more rooms, and a method for setting such a control system into operation.
The present invention relates to an improvement of the known system and method.
2. Description of the Related Art
From EP 0 433 527 there is known a method of setting into operation a control system for several appliances in distributed arrangement, in particular light fittings in one or more rooms, which appliances contain a stored original address and, after their installation has taken place without regard to the original address, are to be controllable from at least one command generator via a common control line, having the following steps: original addresses and stores these original addresses; with the command that the associated appliance should deliver an externally detectable identification signal, the one appliance, command generator an operational address associated with this appliance, which takes into account a particular grouping and/or arrangement of the appliances after the installation of the system, its original address, and there is transferred to the appliance, for storage, the entered operational address, transferred to all appliances.
The main advantage of the known control system, and of the method of setting into operation such a control system, is that the appliances--although they can be installed without consideration being given to their original addresses--can, after the setting into operation of the system, be selected in an aimed manner via their operational addresses taking into consideration various selection criteria.
However, the known system and the method for setting the system into operation have the disadvantage, in particular in the case of large buildings with many appliances, that an appliance which has identified itself--e.g. a light fitting that has been controlled to be brighter--must be sought over the whole building and there is no indication where the search should be begun, since the selection of the appliances by the command generator via their original addresses in accordance with step b) of the known method occurs practically randomly.
SUMMARY OF THE INVENTION
A object of the present invention is to improve the control system and the method for setting the control system into operation to the effect that the above-described disadvantage is avoided and the bringing into operation is simplified and takes less time.
This object is achieved in accordance with the invention by means of an identification detector connected with a command generator so that, by means of the identification detector the identification of selected appliances can be determined, and by means of which the command generator is caused, upon identification of the selected appliance, to write into a memory of the appliance, its operational address and to preset the address in the command generator.
According to a further feature of the invention, there is provided an externally accessible receiver, such as a light sensor, by means of which a command can be given to transmit the original address to the command generator. In respond to such command, the command generator transmits a preset operational address to the selected appliance for writing into the memory of the appliance. Alternatively, the operational address can be directly delivered to the selected appliance for writing into the memory of the appliance by an external transmitter.
According to another aspect of the invention there is provided a novel method for setting into operation a control system for several appliances in distributed arrangement. This novel method involves first, the step of causing a command generator to instruct all appliances to transmit their original addresses to be stored in the command generator. Then, one appliance is selected and an operational address associated with the selected appliance is preset in the command generator. Different or
