Circuit arrangement for controlling jammers
(Addition to P 21 44 816.8)

The invention relates to a circuit arrangement for controlling disturbances by at least two command generators, one of which comprises a central point and the other a single control point, wherein the mutually interlocked control signals for opposite adjustment movements to separate Memory are given that control an actuator, and a control signal from the central office for one adjustment direction clears the memory for the other adjustment direction

and controls the actuator for an adjustment direction, according to patent ... (P 21 44 816.8).

Control, for example, the up and down movement of external venetian blinds and roller blinds should on the one hand be effected centrally for an entire building or part of a building. On the other hand, there is the desire to be able to adjust such store individually. The central control point is touching here one or more sensors, such as sun, wind, humidity and noise monitors. In Depending on the received values, the central control station sends control signals to the various Servomotors delivered, whereby these motors depending on the received control signals cause the blind to move up or down. In addition, each servomotor should be individual be actuated, for example, to set the lighting conditions differently in different rooms to be able to. For this purpose, a single control point is provided, with which, for example, the and downward movement can be controlled by hand. The central control signals are the signals superordinate to the individual control point.

A circuit arrangement of this type is described in German Offenlegungsschrift No. 2,144,816. The aim of the present invention is to further develop and improve the known embodiment.

There it is felt to be disadvantageous that control lines and power lines are galvanic are not separated from each other. The control line must therefore also be declared as a power line and executed accordingly. This brings with it a considerable increase in the cost of the installation themselves.

In addition, not all control options are used in the known embodiment. Change If, for example, the position of the sun or light conditions change, then up to all corrections are made by the central unit only possible because the disturbances are moved up or down. A finer and often more advantageous one The type of correction, however, consists in rocking the blind slats.

The object of the present invention is therefore to eliminate the disadvantages outlined.

This is achieved according to the invention in that the control electrodes of the switching elements of blocking oscillators which are controlled by the amplified, automatically or manually effected control signals to be triggered.

In addition, a comparative light value measuring device is provided which, when the value exceeds or falls below a

409884/0219

6438/22 / UO / sr - 4-4 July 1973

Setpoint light area emits signals to rock the blind slats and only then a command to the control center to trigger a blind movement when the target light value is reached by rocking the Blind slats is not reached.

The invention is explained below using an exemplary embodiment:

The circuit arrangement shown in the figure is a blind control with a Blind drive motor 8, which in one direction of rotation an upward movement and in the other direction of rotation causes the blind slats to move downwards. From a central command point inputs 1 and 3 output control signals A and B. Signal A at input 1 should move upwards and the signal B at input 3 cause a downward movement.

The signal A reaches the blocking oscillator 24 via an amplifier 4 as an amplified signal A ^1. This is an LC generator which oscillates only when a signal is applied to the terminal 25. The generated signals are decoupled via the pulse transmitter 26 and fed to the control electrode 6 of the triac 7. It has proven to be useful to provide feedback for the blocking oscillator by means of an additional winding on the pulse transfer.

409884/0219

6438/22 / UO / sr - 5-4 July 1973

If the blocking oscillator 24 vibrates and a signal is sent to the control electrode 6 as a result, it is the triac 7 conductive.

When a signal B occurs, it is amplified in the amplifier 5 and triggers ^{the blocking oscillator 27 as signal B 1} , the decoupled signal of which reaches the control electrode 20 of a further triac 21. This becomes conductive as a result, so that the motor 8 is now connected to the supply terminal 22 via the triac 21. The motor is a single-phase capacitor motor which now rotates in the opposite direction when fed via the triac 21. The motor 8 is connected to the neutral conductor via terminal 23.

If an upward movement is to be effected by hand, the button 9 is pressed until the switch 11 closes. As a result, a signal a reaches the memory 13, which then emits a continuous signal a ^f via the blocking oscillator 24 to the control electrode 6 of the triac 7. The motor 8 is thus energized via the triac 7. When the upper blind end position is reached, the limit switch 15 is actuated, a signal d being tapped from the motor at the same time. This signal d reaches a reset stage 17 which ^{emits a reset signal d 1} to the memory 13. This erases the memory 13 so that the signal a 'disappears.

6438/22 / UO / sr - 6-4 July 1973

If a downward movement is desired, the button 10 is actuated until the contact 12 is closed. As a result, a signal b reaches the memory 14, which then emits a continuous signal b ¹ via the blocking oscillator 27 to the control electrode 20, so that the triac 21 now becomes conductive. As a result, the motor 8 is now energized via the triac 21 and rotates downwards in the opposite direction. When the lower blind end position is reached, the limit switch 16 is actuated and a signal e is picked up by the motor and fed to the reset stage 17. The reset signal e ¹ causes the memory 14 to be erased, so that the memory ^{signal b 1} disappears.

The reset signals d and e are in the reset stage 17, for example by a not shown Transformer, galvanically isolated from the control signals.

The priority control signal A for the upward movement is the amplifier 4 of a reset stage 18, which emits a reset signal f to the memory 14. For example, if one occurs Signal A (upward) of the memory 14 is acted upon by a signal b (downward), then the memory 14 cleared by the signal f, so that the triac 21 blocks and the triac 7 by the signal A alone becomes conductive.

The same applies in a corresponding manner to the priority signal B. This priority signal B reaches a reset stage 19 which sends a reset signal g to memory 13. A central downward signal B thus makes a manual upward signal given simultaneously or in advance a ineffective.

Each button 9 or 10 has a first and a second switching level. The tasks of the second switching levels 11 and 12 have already been described above. The switching level 11 corresponds to the command "up" and the switching level 12 to the command ^M down ". When the first switching level 18 of the button 9 is actuated, a short-term signal a ^{w is sent} to the amplifier 4 and is transmitted from there as an amplified signal a"'via the Blocking oscillator 24 passed to control electrode 6. In this way, the blind slats can be finely rocked in an upward direction.

If the first switching level 19 of the pushbutton 10 is actuated, a control signal b ″ reaches the amplifier 5 and is passed as an amplified signal b ^MI via the blocking oscillator 27 to the control electrode 20. This causes the triac 21 to conduct for a short time, causing the blind slats to teeter in the downward direction leads.

The signal a "reaches the reset stage at the same time 18 and causes a reset signal f for the

409884/0219

6438/22 / UO / sr - 8 - 4 July 1973

Memory 14. Became memory 14 by a signal b is applied, then by actuating the first switching level 18, the adjustment movement in the downward direction being stopped.

In a preferred embodiment, the signals a ″ and b ″ can also be automatic as well as manually to be triggered. For this purpose, a comparison light value measuring device 28 is provided, which is used to ensure compliance a certain, predetermined brightness value is responsible. When crossing an upper or falling below a lower limit value, it emits corresponding signals a "or b", whereby a corresponding rocking of the blind slats and an adaptation of the lighting conditions to the Setpoint occurs. Only when the desired brightness value can no longer be set by rocking it in is, a command 29 for upward or downward movement is passed on to the control center.

If the memory was .13 by an upward signal a is applied, then the memory 13 can upon actuation the first switching level 19 of the button 10 are deleted because the signal b "the reset stages 19 is applied, which in turn emits a reset signal g to the memory 13.

The control signals a, b, a "and b" are from a Impulse line tapped from the control center. To the-

For this purpose, square-wave pulses C arrive at terminal 2. Terminal 2 is in turn connected with Kontaktenil, 12, 18 and 19. When you press the first switching level 18 or 19, only a few get there Pulses to the associated triac 7 or 21, which is controlled in a pulsed manner. Through this control the motor 8 also receives only brief voltage surges. These voltage surges are based on the phase control principle so low that the slats are adjusted slowly and evenly. Here is cut at the zero crossing, so that there is practically no need for interference suppression.

If an upward or downward movement of the slats is caused by the motor 8, then the duration of the signals A, B, a ^f and b ^{1 is} limited to about 3 to 4 minutes. This duration is greater than the adjustment time between the upper and lower blind end position.
