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 nacessary. 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
2~8~5 to all these devices is the fact that each individual consumer is operatad 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 operatiny 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.

This object is achieved according to the inven-tion 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 transfer-ring 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 correspon-ding to a memory location number, the current state of 2~8~

DESCRIPTION OF THE PREFERR~D EMBO~IMENTS
Fig. 1 shows the basic design of an infrared remote-controlled operation system for electrical con-sumers. Various consumers, here light fixtures 13, audio unit 14 and window blinds 15 for example, are controlled by control devices 12 by means of an operating device 11 which is designed in the form of a hand-held transmitter.
Said consumers can be switched on and off, or controlled if re~uired, dependin~ on the function range of the control devices 12.
Fig. 2 shows the schematic block circuit diagram of a control device 12. The signals transmitted by the transmitter are received by means of a receiver 16 and are supplied to an evaluation unit 17. Said evaluation unit 17 evaluates the signals S1 supplied to it and drives a control unit 18 accordingly. An electrical consumer is connected to said control unit 18. For light 2 ~ 4 ~
fixtures, for example, said control unit 18 is designed in such a way that it can vary the light intensity of the light fixture by controlling the current. Corresponding control signals come from the evaluation unit 17 in this case.
The receiver 16 comprises a receive diode Dl which converts infrared sigr,als into current, and a preamplifier 20 which conditions the weak current signals received in such a way that they can be processed further by a downstream microprocessor or ASIC 21 of the evalu-ation unit.
The transmission of commands between the trans mitter (operating device ll) and the receivers 16 of the control devices 12 is based on individual infrared command telegrams, in which the information is diqitally encoded. Each telegram contains at least one address field with address bits and one data Pield with data bits.
The evaluatiorl unit 17 (Fig. 2) contains, for example, two coding switches 22 to determine a device address A (3 least signiicant bits) and a group address G (3 most significant bits). The microprocessor or ASIC
21 reads in said addresses (G, A) when a command telegram is received and compares the address field with the address set at the receiver 16. If the addresses match, the command is stored or further processing.
A pl~rality of control devices 12 can be addressed with an operating device ll by means of the address coding of the command telegrams.
.
20880A~
Specific special commands are preferably trans-mitted as special addresses in the address field of a telegram, it being possible for all the control devices to receive and execute said special commands together.
In order to store a current state of the control unit 18 and hence of the consumer, for example the light fixture, the evaluation unit 17 contains a memory 23 (RAM
or EEPROM).
The memory 23 permits the storage of states for driving the control unit 18. The microprocessor or ASIC
is notified via m MODE inputs 24 which type of control unit 18 is to be driven, whereupon it then calls up the corresponding program in the program memory 25 (ROM). It is thus possible to generate a plurality of different control slgnals S2 for various control units (for example generalized phase control, relay, etc.) with a single microprocessor or ASIC, to be precise depending on the MODE inputs.
The memory 23 contains a state register 26 which stores the current state oE the control device, that is to say the actuation values for driving the control un:it (Fig. 3).
The current state of the control device 12 can be stored, activated, deleted or temporarily deactivated in the evaluation unit 17 of the control device 12 by correspondinq commands or scenario commands of the operating device. The microprocessor or ASIC 21 transfers the current state from the state register 26 into a state table 27 of the memory 23 by means of a store command.
~8~
Said state can be called up again by means of a re-trieve command, in which case the microprocessor or ASIC 21 transfers the desired state from the state table into the state register and uses it as the current state value for driving the control unit.
The state table 27 is preferably designed with sufficient capacity for storing a plurality of states.
The use of a separate converter 2~, as illus-trated diagrammatically in Fig. 4, proves to be particu-larly advantageous. Said converter is positioned at the most suitable location in the room and has as its task the amplification and forwarding of the signals emitted by the operating device 11.
The control devices 12a and 12b, for example, are driven by the operating device 11, in which cas~ the converter 28 simultaneously receives the commands and is able to retransmit them amplified after a short time (approx. 1 ms). The control devices are designed in such a way that any duplicated reception of a command is correctly interpreted.
According to a preferred embodiment (Fig. 5), the operating device 11 comprises a keypad 29 with 4 Xeys Tl, T2, T3, T4, a microprocessor or ASIC 30, an address presetting means 31 and a transmitter stage.
When any of the keys (Tl, ... T4) is pressed, thQ
output signal S3 of the keypad 29 is read in by the microprocessor or ASIC 30 and indicates which key on the keypad was pressed. The microprocessor or ASIC 30 gener-ates a signal S4 thsrefrom, which selects, by means of a 8 2 ~ s logic circuit 32 of the address presetting means 31, a device address set on the operating device with the aid of coding switches A1, A2, A3, A4.
Each key of the keypad is assigned to exactly one of said device addresses. The selected device address A5 determines the 3 least significant bits of the address field in the telegram, and is read in by the micropro-cessor or ASIC 30. At the same time a group address set with a coding switch Gl is read in by the microprocessor or ASIC 30 and determines the 3 most significant address bits of the telegram.
The microprocessor or ASIC 30 generates a control signal S5. The control signal S5 contains address bits (A5, Gl) and data bits, which correspond to the length of the key depression for example. The control signal S5 controls a current source 33 connected in series with a transmit diode ~2. The diode D2 generates a light signal in the infrared range in accordance with the current.
According to a preferred embodiment, the scenario commands are triggered by the converter 28. All the control devices 12 situated within the receiving range of the converter 28 can receive said scenario co~nands regardless of the address (G, A, Fig. 2) set on the control device. The totality of all the actuation values which can be stored with a scenarlo command in the accessible control devices is termed a scenario; this may be a lighting mood, for example, if all the control devices 12 contain control units 18 for controlling luminaires.
- 9 -~
A total of five commands can be executed: store scenario (spontaneously or selectively), retrieve scen-ario, delete scenario, delete all scenarios.
The converter 28 contains (Fig. 6) a receiving part, a microprocessor or ASIC 34, a keypad 35 and a transmitting part.
The receiving part compri~es a receive diode D3 which converts the infrared signals into current, and a preamplifier 36 which conditions the weak current signals received in such a way that they can be processed further by the downstream microprocessor or ASIC 34. The trans-mitting part comprises a current source :~7 which is connected in series with at least one transmit diode D4 and which is controlled by control signals S6 of the microprocessor or ASIC 34.
The keypad 35 contains three keys, a MEMO key TM, a SELECT key TS and a DELETE key TD, which can be read by the microprocessor or ASIC 34.
A memory 38 (RAM or EEPROM) of the converter 28 contains a scenario table 39 (Figure 7) with n memory locations (n = 16 for example), with corresponding memo:ry location numbers (1, 2, 3, ... n).
The state tables 27 of the control devices (Fig. 3) also contain n memory locations with correspon-ding memory location numbers 1, 2, 3. ... n.
The system permits the storage of set states of all the control devices within the receiving range of the converter 28. n scenarios can be stored in any number of control devices.
2~8~
Once the control devices 12 have been set as desired with the operating device 11, the MEMO key TM is pressed on the converter ~8. As a result, the micropro-cessor or ASIC 3~ of the converter 28 is prepared to interpret the address field of the next telegram received from the operating device 11 as a scenario command. A key is now pressed on the operating device with which the relevant scenario is to be called up in Euture. The various memory locations of the scenario table 39 are searched through for the corresponding telegram address in the converter 28. If the address is fvund, the corre-sponding memory location number is read out by the microprocessor or ASIC 34. If the address i9 not found, the first free memory location in the scenario table 39 is sought, the address is stored and the corresponding memory location number is read out.
If the scenario table 39 is full, this is indi-cated to the user by a flashing warning message. In order for it to be possible to program a naw scenario in this case, an existing scenario must first be deleted~ A store command with the memory location number read out is then sent by the converter 28 to all control devices as the scenario number. According to Figure 3, the current state ~actuation value for the control unit) is entered in the state table in the control device under the corresponding memory location number, the existing actuation value being thereby overwritten.
Figs. 3 and 7 shows the storage of two scenarios by way of example. The already stored first scenario with 2 0 ~
scenaxio number 1 corresponds to the telegram address GlA1 which is activated by key Tl of an operating device with group address G1 (Fig. 5). The address GlA1 is stored in the memory location number l of the scenario table 39 and the corresponding state Z1 is stored in the memory location number 1 of the state table 27 of a control device. To store a scenario corresponding to a state Z2, said state is first set using the control device 11. The key TM is then pressed followed by the key T3 of the operating device. The operating device sends a telegram with the address GlA3. Said acldress is inter-preted by the converter as a scenario command and the address GlA3 is sought in the scenario table 39. Since only scenario 1 is stored in the scenario table, all other memory locations 2, 3, ... n are empty.
The address GlA3 is stored in the next empty memory location and the corresponding memory location number (2) is sent as scenario number 2 with a storP
command by the converter 28. All the control devices 12 within the receiving range receive said store command with scenario number 2. The current state Z2 of the state register 26 is transferred into the memory location number 2 of the state table 27.
A scenario is called up by pressing the ]cey assigned to the scenario on the operating device. The microprocessor or ASIC 34 of the converter 28 searches in the scenario table ~ig. 7) for the address from the address field of the telegram transmitted by the operat-ing device. If the address is found, a scenario retrieve command with corrasponding scenario number is sent to the control devicas, otherwise the received telegram is retransmitted after amplification. The scenario retrieve command is handled as follows in the control device:
If the state value stored under the scenario number is not found to be empty (not defined), the state value is transferred into the state register 26 as current state value for driving the control unit.
If, for example, the scenario 1 is to be called up, then for example the key Tl of the operating device 11 is pressed. The microprocessor or ASIC 34 of the converter 28 finds the corresponding addrass GlAl in the memory location 1 of the scenario table 39 and sends a retrieve command with the scenario number 1. In the control device, the microprocessor or ASIC 17 detects the retrieve command and transfers the state value Zl, which is stored in the memory location 1 of the state table 27, into the state register 26.
With this method only the assignment between the key on the operating device (with set address) and the scenario is evident to the user, the system selects the corresponding scenario numbers independently.
The system preferably permits a selective pro-gramming of a scenario. In this case a scenario is consciously programmed and individual control devices can be consciously declared as not belonging to the scenario.
No entry is made under the corresponding scenario number for these control devices in the state table.
In order not to use a separate store and retrieve ~8~
_ 13 -command for each control device, a reset signal which mark~ all the axisting control devices as not affected i8 preferably ~ransmitted before a state is stored.
A reset signal is sent by the converter 28 by pressing the S~LECT key TS of the converter 28. Each control device that receives said reset signal will detect it and mark itself as not affected. A control device marked as not affected will ignore the next store command. If the state value stored in the state register 26 of the control device is now altered, by means of any control signal sent specifically to it rom the operating device, then, in addition to the execution of the corre-sponding action, said control device is marked a~ active.
If a control device marked as active now receives a store command, then the current state is transferred into the sta~e table. In this way all the control device~ who~e Ytate was altered in some way or other since reception of the reset signal are incorporated in the scenario.
Once all the desired control devices have been set to the correspondin~ state, the MEMO key TM must be pressed on the converter. The further procedure is the same as in the scenario storage described above, except that the state value is stored only at the active control device~. The SELECT mode is reset at the same tLme.
It is thus possible to set, for example, a room atmosphere individually by means of the installed light fixtures and to store this state. Said state can then be re-established at any time simply by pressing a key. It is particularly advantageous here that the consumers not 2 ~
belonging to the scanario are not influenced thereby. If table ~7 is used to store a plurality of states, then, for example, several u~ers can store their inclividual settings and call them up again at any time under the corresponding scenario number.
This selective programming is used especially in situations where consumers are to be excluded from a scenaxio, for example if a radio is to be switched on and off by means of a control device irrespective of the desired lighting scenario.
A scenario assigned to a ksy of the operating device can be deleted by pressing the DELETE key TD on the converter, whereupon ths converter is prepared to use the address of the next telegram as the address ~or the scenario to be deleted. The key assigned to the scenario must then be pressed on the operatiny device. In the converter 28, the scenario number corresponding to the address is sought in the scenario table 39, and if it is found, the address entry is set to empty (not defined), then a scenario delete command with this scenario number is sent to all control devices. The actuation value is set there in the state table 27 to empty (not defined) under the corresponding scenario number.
According to a preferred embodiment, all scen-arios can be deleted simultaneously by pressing the DELETE key TD of the converter longex than a specified time, for example 5 s.
All the entries in the scenario table 39 are then set to empty and a special command is sent to the control 2 ~ 4 ~
devices to delete all scenarios. All the memory locations in the state table are set to empty therein.
All scenario commands, that is to say store commands, retrieve commands, delete commands and reset signals, are preerably transEerred as special addresses into the address field of a telegram. Each control device then reacts to the reception of said scenario command, in which case the necessary scenario number is t~en trans-mitted in the data field of the telegram if necessary.
The following addresses may correspond to the following scenario commands by way of example:
Store command : 111 l~O
Retrieve command : 111 lO1 Delete command : 111 100 Reset signal : 111 011
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 inven-tion 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 transfer-ring 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 correspon-ding to a memory location number, the current state of 2~8~
the control unit being transferred into the corresponding memory location o~ the state table.
When a retrieve command with a corresponding scenario number is received, the state of the correspon-ding memory location of the state tab].e is transerred into the state register.
The operation system preferably contains means for the selective stora~e of a scenario in selected control devices.
A further embodiment of the invention is one wherein it contains a separate converter which retrans-mits the control signals received from the operating device and processes commands received from the operating device and retransmits them as scenario commands.

A memory 38 (RAM or EEPROM) of the converter 28 contains a scenario table 39 (Figure 7) with n memory locations (n = 16 for example), with corresponding memo:ry location numbers (1, 2, 3, ... n).
The state tables 27 of the control devices (Fig. 3) also contain n memory locations with correspon-ding memory location numbers 1, 2, 3. ... n.
The system permits the storage of set states of all the control devices within the receiving range of the converter 28. n scenarios can be stored in any number of control devices.
2~8~
Once the control devices 12 have been set as desired with the operating device 11, the MEMO key TM is pressed on the converter ~8. As a result, the micropro-cessor or ASIC 3~ of the converter 28 is prepared to interpret the address field of the next telegram received from the operating device 11 as a scenario command. A key is now pressed on the operating device with which the relevant scenario is to be called up in Euture. The various memory locations of the scenario table 39 are searched through for the corresponding telegram address in the converter 28. If the address is fvund, the corre-sponding memory location number is read out by the microprocessor or ASIC 34. If the address i9 not found, the first free memory location in the scenario table 39 is sought, the address is stored and the corresponding memory location number is read out.
If the scenario table 39 is full, this is indi-cated to the user by a flashing warning message. In order for it to be possible to program a naw scenario in this case, an existing scenario must first be deleted~ A store command with the memory location number read out is then sent by the converter 28 to all control devices as the scenario number. According to Figure 3, the current state ~actuation value for the control unit) is entered in the state table in the control device under the corresponding memory location number, the existing actuation value being thereby overwritten.
Figs. 3 and 7 shows the storage of two scenarios by way of example. The already stored first scenario with 2 0 ~
scenaxio number 1 corresponds to the telegram address GlA1 which is activated by key Tl of an operating device with group address G1 (Fig. 5). The address GlA1 is stored in the memory location number l of the scenario table 39 and the corresponding state Z1 is stored in the memory location number 1 of the state table 27 of a control device. To store a scenario corresponding to a state Z2, said state is first set using the control device 11. The key TM is then pressed followed by the key T3 of the operating device. The operating device sends a telegram with the address GlA3. Said acldress is inter-preted by the converter as a scenario command and the address GlA3 is sought in the scenario table 39. Since only scenario 1 is stored in the scenario table, all other memory locations 2, 3, ... n are empty.
The address GlA3 is stored in the next empty memory location and the corresponding memory location number (2) is sent as scenario number 2 with a storP
command by the converter 28. All the control devices 12 within the receiving range receive said store command with scenario number 2. The current state Z2 of the state register 26 is transferred into the memory location number 2 of the state table 27.
A scenario is called up by pressing the ]cey assigned to the scenario on the operating device. The microprocessor or ASIC 34 of the converter 28 searches in the scenario table ~ig. 7) for the address from the address field of the telegram transmitted by the operat-ing device. If the address is found, a scenario retrieve command with corrasponding scenario number is sent to the control devicas, otherwise the received telegram is retransmitted after amplification. The scenario retrieve command is handled as follows in the control device:
If the state value stored under the scenario number is not found to be empty (not defined), the state value is transferred into the state register 26 as current state value for driving the control unit.
If, for example, the scenario 1 is to be called up, then for example the key Tl of the operating device 11 is pressed. The microprocessor or ASIC 34 of the converter 28 finds the corresponding addrass GlAl in the memory location 1 of the scenario table 39 and sends a retrieve command with the scenario number 1. In the control device, the microprocessor or ASIC 17 detects the retrieve command and transfers the state value Zl, which is stored in the memory location 1 of the state table 27, into the state register 26.
With this method only the assignment between the key on the operating device (with set address) and the scenario is evident to the user, the system selects the corresponding scenario numbers independently.
The system preferably permits a selective pro-gramming of a scenario. In this case a scenario is consciously programmed and individual control devices can be consciously declared as not belonging to the scenario.
No entry is made under the corresponding scenario number for these control devices in the state table.
In order not to use a separate store and retrieve ~8~
_ 13 -command for each control device, a reset signal which mark~ all the axisting control devices as not affected i8 preferably ~ransmitted before a state is stored.
A reset signal is sent by the converter 28 by pressing the S~LECT key TS of the converter 28. Each control device that receives said reset signal will detect it and mark itself as not affected. A control device marked as not affected will ignore the next store command. If the state value stored in the state register 26 of the control device is now altered, by means of any control signal sent specifically to it rom the operating device, then, in addition to the execution of the corre-sponding action, said control device is marked a~ active.
If a control device marked as active now receives a store command, then the current state is transferred into the sta~e table. In this way all the control device~ who~e Ytate was altered in some way or other since reception of the reset signal are incorporated in the scenario.
Once all the desired control devices have been set to the correspondin~ state, the MEMO key TM must be pressed on the converter. The further procedure is the same as in the scenario storage described above, except that the state value is stored only at the active control device~. The SELECT mode is reset at the same tLme.
It is thus possible to set, for example, a room atmosphere individually by means of the installed light fixtures and to store this state. Said state can then be re-established at any time simply by pressing a key. It is particularly advantageous here that the consumers not 2 ~
belonging to the scanario are not influenced thereby. If table ~7 is used to store a plurality of states, then, for example, several u~ers can store their inclividual settings and call them up again at any time under the corresponding scenario number.
This selective programming is used especially in situations where consumers are to be excluded from a scenaxio, for example if a radio is to be switched on and off by means of a control device irrespective of the desired lighting scenario.
A scenario assigned to a ksy of the operating device can be deleted by pressing the DELETE key TD on the converter, whereupon ths converter is prepared to use the address of the next telegram as the address ~or the scenario to be deleted. The key assigned to the scenario must then be pressed on the operatiny device. In the converter 28, the scenario number corresponding to the address is sought in the scenario table 39, and if it is found, the address entry is set to empty (not defined), then a scenario delete command with this scenario number is sent to all control devices. The actuation value is set there in the state table 27 to empty (not defined) under the corresponding scenario number.
According to a preferred embodiment, all scen-arios can be deleted simultaneously by pressing the DELETE key TD of the converter longex than a specified time, for example 5 s.
All the entries in the scenario table 39 are then set to empty and a special command is sent to the control 2 ~ 4 ~
devices to delete all scenarios. All the memory locations in the state table are set to empty therein.
All scenario commands, that is to say store commands, retrieve commands, delete commands and reset signals, are preerably transEerred as special addresses into the address field of a telegram. Each control device then reacts to the reception of said scenario command, in which case the necessary scenario number is t~en trans-mitted in the data field of the telegram if necessary.
The following addresses may correspond to the following scenario commands by way of example:
Store command : 111 l~O
Retrieve command : 111 lO1 Delete command : 111 100 Reset signal : 111 011
