Description

The invention relates to the regulation of film studios, television studios and theaters. A device for controlling lighting is known, for example a commercially available Light-type controller for theaters and television studios, which contains potentiometers and a follower drive associated with a manual controller and programming part 1. Potentiometers and the mechanical part of the follower drive are extremely non-. are reliable in operation, and the programming part of the device is made on digital elements, it requires the presence of voltage converters in the code for recording information and a code in voltage for reproducing it. The closest technical solution to the proposed is a device for automatic dimming, which contains an individual controller, the outputs of which are connected to the inputs of reversible counters installed in control channels, performed on digital elements. Such a construction has made the device easier and more reliable in operation 2. However, the known device does not provide a smooth transition from one light program to another, for example, necessary in theaters. It does not solve the issue of group regulation, which is of paramount importance for television studios. In addition, this device is built on the principle of passport control, which makes it structurally complex. The purpose of the proposal is to expand the field of application of the proposed device. The goal is achieved by introducing program, control channel and control circuit switches and in each control channel serially connected common and group controllers, and the number of control circuits sequentially connected by the number of control circuits control signals are aggregators, and the inputs of the control signal generation units are connected respectively to the outputs of the group controller, the reversible counter and the switch control circuits, the second outputs of the control syn forma formation blocks are connected to the input of the reversible counter, to the Third input of which the output of the control channel switch is connected, and the outputs of the program switch are connected to the outputs of the dead, new regulators, and also because The controls contain a g-code converter, the input of which is “e & the elements of AND are connected to the first block of the unit, and the outputs of the keys are connected through the second output of the block, the second inputs of the AND elements are connected to the third input of the block, the output of the converter is the code-voltage connected to the first inputs of the group elements I, the second inputs Which are connected to the first input of the block, and the third inputs are connected to the memory elements of the groups, and the group elements AND are connected to the inputs of the OR element, the output of the fluorine is connected to the first output of the control signal generating unit.

The Operator Lighting Control Unit (Fig. 1) contains, for each control channel, a five-bit, reversible counter 1 (1), which receives permission for counting pulses from the 2-channel control switch and from the individual controller 3. Reversible counter outputs 1 (1 the bottom is connected to 40 4 (4 formations of the control signal of all adjustable chains. On the other hand, blocks 4 (4 are manually controlled by common controller 5 (5 and group p. b).

At any given time, the signals from the reversible counter 1 (l) can only flow into one control signal generating unit, which is achieved thanks to the pledged vosnov building of the device to the principle of selective control; namely, using the control switches 7. 4 (4) control signal NIN-signal is registered-serialized and converted to a level, control voltage, determined by the state of the reversible counter l {ljt output voltage of blocks 4 (4) for each adjustable sum circuit are simulated, and the output voltages of the capacitors 60 are 8, the output voltages of the control device. To implement a smooth automatic transition from one light program to another, the device is turned off from 5

common controller 5 (5 and connects to the switch 9 programs.

The operator lighting control unit in studios operates in two main modes: installation: light, i.e. preparation of light programs; reproduction of previously prepared light programs.

The operation of the device is as follows.

After supplying power to the device, it is necessary to select a control channel (1 or II, on which a given light program will be installed. This is done by pressing one of the buttons of control channel selector 2. General regulator 5 (5} of the selected channel to enter from zero to 100%. Then, one of the group regulators 6 (6} of the selected channel is put into operation) and the set light level is set sequentially for each adjustable circuit. To do this, the sequence number of the circuit is pressed by pressing the corresponding buttons. The flasks are hundreds, tens and control switch units 7.

The output signal of the control switch 7 (Fig. 2) permits the transfer of information from the reversible counter l (lj to block 4 (4) of generating the control signal of the selected circuit, since the outputs of the reversible counter l (iO are connected by its inputs / gs of the 10 keys of the ll converter (llj code to the voltage through the elements And, to the second inputs of which the signal comes from the output of the switch 7 control circuits, and the third inputs are connected to the buttons Addition 12 and Subtraction 13 of the individual controller 3. Therefore, when you press the button 12 (or 13) reversible counter start stumbles pulses keys 10 (w) of the selected circuit follows the reversible counter 1 (1), and the output transducer 11 (ll) code voltage stepwise vary the voltage in the direction of increasing (or decreasing).

Claims (2)

The output signal from the converter d of the code to the voltage goes to the first inputs of six (by the number of adjustment groups) group elements 14 And the selected control channel (Fig. 3). The second inputs of the group elements I receive a signal from the corresponding group controller 15 (15 group regulators b (b). On the third inputs, the signal proceeds as follows: each group has its own button 16 and the memory cell is a trigger -17 with two elements 18 and 19 and at the input. The excited state of the trigger 17 determines the connection of the circuit to the group. The trigger 17 is energized (i.e. it is in one state if two signals appear at the input of its element 18 And the signal from the button 16 o selected group and si The number of the selected circuit from the control switch 7 is selected. Selecting the circuit number with the group button 16 turned off triggers trigger 17 to zero status, disconnecting this circuit from groups. Thus, the output of group elements 14 (14 And a signal appears at the input three signals match the signal from the converter output to voltage 11 (11), the signal from the corresponding group controller and the signal from the excited voltage trigger from the output of the group elements 14 (l4j AND through the OR element, the circuit 20 enters the input of the adder S Since Currently voltage of the second channel output voltage is equal to zero, the output voltage of the selected circuit is determined only by the level of the signal outputs of the first channel. If the light program must be a combination of the same lighting devices installed individually on other levels of supply voltage, then such a light program must be selected on the second control channel. If for the shooting of a film several light programs are necessary, and such a volume of information cannot simultaneously be placed in the control device, then a light score is composed of the light programs in the necessary sequence and recorded in a special journal. The operation of the control device in the playback mode of the previously prepared light programs proceeds as follows. After the supply voltage is applied, the control channel is selected to record information about the first program. Common controller 5 (SJ and the corresponding group controller 15 (you can not set to 100% so as not to light the lights in the studio. In accordance with the recorded program, the numbers of the circuits connected to the selected group are selected and the output signal level is set each circuit. Next, the next adjustment group is selected and the output levels of the circuits connected to this group are set. In this way, the successive light programs are restored according to the light part; all groups and both control channels. If it is necessary to make a smooth transition from one light program to another, then this operation can be done either manually by shifting the common controller 5 of the first channel from the 100% position to zero, while the common controller slider 5 the second channel is transferred from zero to the lOOS position or automatically using program switch 9, for which pressing the button 21 (21) the Automatic group controllers b and (b) push the buttons from the common controllers 5- and (5) and connect to switch programs 9. Co. where nebodimost: in the first light pictures disappear in their place, the subsequent light is recorded, the program in the dark without disturbing the actual light in the studio. If there is a large amount of memory in the form of random-access memory of RAM or long-term storage of DZR or IR memory; 1) Ormaci is transferred from RAM or DZU to the lOfl keys of the iflj counter.
