DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a remote-controlled operation system for electrical consumers which has an operating device with a transmitter and at least one control device with a receiver, to which the electrical consumers are connected, the control device having an evaluation unit which evaluates signals received from the transmitter and a control unit for the consumer to be connected.
PRIOR ART
A wide variety of control means or operating means exist in particular for household electrical consumers such as light fixtures, audio equipment, light protection systems such as sun blinds and the like. The majority of such electrical consumers are customarily operated by means of switches situated directly in the power leads, that is to say are switched on and off, and are also controlled if necessary. Frequently audio equipment such as television sets and HiFi units, in particular, is customarily operated by means of remote controllers, in which case the devices are usually provided with a constant power supply via the power supply network. Remote-controlled switches for light fixtures are also already in use in a few cases. Common to all these devices is the fact that each individual consumer is operated using its own operating means, that is to say, for example, when there are a large number of devices in a room, a plurality of transmitting devices are required and are present for operating the individual consumers.
The object of the present invention is then the capability of remote-controlled operation of a plurality of electrical consumers by means of a control system and at the same time the ability to store preset states of the various consumers and call them up again simply when required.
SUMMARY OF THE INVENTION
This object is achieved according to the invention in that the evaluation unit contains storage means for storing at least one state of the control unit, which is driven according to the evaluation of the evaluation unit.
The storage means preferably contains a state register and a state table, the evaluation unit transferring the current state of the control unit used for controlling the control unit from the state register into the state table when a store command is received.
In accordance with a preferred embodiment, the state table contains a plurality of memory locations with corresponding memory location numbers, and a store command is transmitted with a scenario number corresponding to a memory location number, the current state of the control unit being transferred into the corresponding memory location of the state table.
When a retrieve command with a corresponding scenario number is received, the state of the corresponding memory location of the state table is transferred into the state register.
The operation system preferably contains means for the selective storage of a scenario in selected control devices.
A further embodiment of the invention is one wherein it contains a separate converter which retransmits the control signals received from the operating device and processes commands received from the operating device and retransmits them as scenario commands.
The converter preferably contains, connected to an evaluation unit, a receiving part, memory, keypad and transmitting part, and the transmission between the operating device, the converter and the control devices is based on individual telegrams with an address field and a data field. The depression of a key on the keypad prepares the evaluation unit of the converter to interpret the address field of the next telegram received from the operating device as a special command and to retransmit it as a scenario command.
