Description

The invention ilpe.UvieTuM is a device for lighting studios of telecentres and theater scenes.

Reliable theatrical light controllers with McIlite amplifiers, which have been widely used in Western Europe and in the Soviet Cijjose, despite significant advantages | C (: before transformer regulators of common types) have a common drawback with them: the entire control equipment is stationary. As a result, the control ciieTOM can be carried out only from one, predetermined, unchanged place, which meets many of the requirements of short-lasting control and considerably complicates There is no process for adjusting light, especially in telecommunication studios of telecentres.Another disadvantage of modern devices is the need for painstaking adjustment during the initial installation of light, performed by moving individual control knobs, which also makes it difficult to operate the knobs.

Known theatrical adjustments with front (niimi pools, directors' controls) are designed to improve the control of light during rehearsals. However, such bulky and expensive devices with heavy cable connections and very limited control functions have not been widely used.

The proposed invention aims to provide the possibility of direct sight of the objects of stage lighting with the greatest speed of action and ease of operation of the entire installation.

It is based on a well-known device for controlling the lighting of television studios and theater scenes, which contains magnetic amplifiers, the outputs of which include lighting devices, and the control windings are potentiometric sensors with a tracking drive mounted on a stationary zero-controller and associated with the drivers potentiometers located on the mobile remote control. The proposed device is characterized in that the mobile remote control is small in size and is used to carry out all the necessary operations, but with manual control and automatic software light control.

The possibility of wide use of the mobile zero is achieved by using a relay system to selectively influence a small number of setpoint potentiometers on the non-potentiometric output-voltage sensor 1P1 of any magnetic amplifier. The relay system is controlled by means of a digital keyboard installed on the small-sized mobile control panel on which the control unit is located. FIG. 1 and 2 are the circuit diagrams of the device with an indication of the communication circuits with magnetic amplifiers, and the equipment of the automatic programming device; in fig; 3 - front view of the control panel movement panel; in fig. 4 — complete set of main devices with cable connection between them. The described lighting control device in the present embodiment has been developed for use in a film production studio of a television center and is designed for 150 controllable circuits by the number of main magnetic amplifiers (MUs) used to power the studio lighting fixtures. On each of the 150 main MUs, the output voltage is regulated by means of a stationary remote controller, on which the potentiometric sensors with the following drive are installed, which are connected to the control winding circuits of the MU. As shown in the circuit diagram of the device, the switching contacts of the 01R-75R passport relays are inserted into the circuits of all w and w, their PS-A and PS-B potentiometers and polarized RP-A, RP-B relays of the controller. When switched on, each of these relays switches its pair of followers, their PS-A and PS-B potentiometers, from the circuits of the programming device to a single, common to the whole device pair of potentiometers PZ-A and PZ-B, located on the mobile remote control. Such switching allows, using one pair of setpoint potentiometers and the follow-up drive of the controller, to provide the possibility of remotely moving the sliders of each control potentiometer PU-A and PU-B to the desired position and, thereby, alternately adjust the voltage of all main MUs, to which the lighting devices are connected. Since the number of C / R-75R passport relays corresponding to the number of pairs of controlled circuits is quite large (in this case 75 relays), the relay was turned on according to the electoral principle using the control keys and JE-9E microswitches (units) and 1Д-9Д (ten) and auxiliary relays ORE, ORD n. Paszort and auxiliary relays are included in the relay relay kit. The microswitches are interlocked with the keyboard’s falling keys (Fig. 3) located on the mobile remote control. connected through the switches П-А П-В on the stationary remote controller. Two control potentiometers YAL / LG-2, located on the mobile remote control bullet, regulate the output voltage of the group MUs. Included: the operation and regulation of the speed of the follow-up drive of the console-regulator was carried out by a submersible drive potentiometer, which changed the operating voltage of the MU, feeding the electric drive motor ED. Button D is normally open (the closing circuit of the MU control activates the drive. The potentiometer PP and KHOI ka are located on the mobile remote control pool. Transferring the device from the manual perj circuits to the automatic programming circuit is one-time disconnecting all the selective relay relays System Management of programming operations: EXECUTE using one of the three buttons: Rec (record), Set (set), General show (general cut), locked with the key shortcut keys, which Positioned on a mobile remote control unit.The control of the execution of one-step automatic programming. The availability of apr power supply of the remote control is carried out using the signal lamps JJ3, LU and Ls (Fig. 1). On the mobile remote control all command and control equipment and signal equipment of the device are placed. Combine in blocks. In the block / under the inscriptions "Group regulation and" Drive j ac the PG-1 potentiometers - group MU and PG-2 - MU drive of the stationary remote controller are installed. In block 2, “Individual regulation,” are located the setting potentiometers and PZ-B OBP.1; it has a pair of controlled circuits. The position of the slider knobs of the potentiometers is marked on the scales along which they move. The divisions of the scales roughly correspond to the percent of the regulated voltage. In block 3, there are three bits of a keyboard with a digital set, the keys of which are used to control automatic programming and for a selective set of controlled circuits. The nine upper keys of each digit (units of li tenths) of the keyboard drop one by one with a mutual return. The bottom key, (without zapadapi) returns to any one of the bit's dead key. Under the keyboard keys, a block of IE-9E microswitches and (Fig. 1) without interlock is mounted, with which, by pressing the keyboard, a circuit breaker (or disconnection) is made in the corresponding circuits of the electric circuit of the device.
