Arrangement for position control of mechanical ¹ construction elements

The invention relates to an arrangement for controlling '_' / _ niftchanisGher. Kanstrnlctiansr and structural elements, such as numeric. ■ rollers: .Type n wheels, ..-, Tjfp en stange η and the like ,? in-i a pre-determined position from a controllable location. A wide variety of methods are known for this purpose, including the so-called analog voltage or current compensation technology. controlling construction ^ - or .Bauelemente assigned a single size of the so-called Meßspammng. By comparing these measurement voltages from the controlling St-e] Ie and from the controlled BaTie, the corresponding voltages are tapped, for example, from S-pnnnungsteil.lern or tap changers, with known technical methods, the agreement or disagreement to control their position eiiifadh.

With each change of the position of the controlling device must downstream, be tracked automatically to be controlled construction elements or components in the changed position, which is by means of uniform electrical Jtnpulse and elektromeclianischer force transducer ,, such as stroke or Örehmagnete and the like ", causes in this method .

With the increasing number of hot such Po.-:: 1 iorisstcuerc inr i gtungen required measuring and control lines it is desired: «rh t, to limit this number as much as possible »

It is therefore the task of the invention to create an anorr 'ü'isi'; for I'o. «i t. i om. «- to create controls of the type mentioned, which with a; · οι-ΐ · ΐ; '- the number of lines gets by.

This object is achieved in accordance with the fact that> the measuring line, the "voltage comparison" between the s t piiormlc'i Location and the construction wire to be controlled serves, at the same time as Lber1: rn;: an ;; the scarf timpul so for dns device to be controlled used v.-i rd, i / o Ii ei the static MoC function Maintain this line during the impulse transmission remain.

This is expediently in such a way that, the voltage divider of the controlling body is connected at its one end directly to one of Spanmmgsversorgungsanschlüsse, while its other end via a normally closed, of egg tu r: ¹ pulse to be controlled switching element at the other voltage. «- supply connection, whereby the switching element: if the positions in the controlling '! ^ erät and dori sr u controlling construction or building Lenient in front of the pulse generator with a fixed predetermined frequency and thus the constant output position measuring voltage is converted into a pulse train with a constant amplitude corresponding to the selected position, which in the controlled devices according to Voltage and power conversion is used for switching the construction or components into the newly specified position.

As the pulses of the analog Positionsiiießspannung with of '■ ■' position to position different Aiiiplittide in · the overall <· <controlled devices --for the stepping of the controlling to-Konstfuktionseleraente used herds -kanh should -Will described in detail below.

The just described pulse train of the analogue position slack must be brought to a necessary power and uniform voltage level in the controlled devices. . For this purpose, the individual impulses in one of the measuring line branched line via a matching amplifier 9 a monostable flip-flop 10 controlled at separate times. This flip-flop has a 0 / L characteristic and consequently only responds to the rising edges of the individual pulses. The switching off of the flip-flop element 10 takes place via its separate timing, i.e. the duration of the output pulses 11 of the flip-flop is independent of the duration of the input pulses.

Appropriately 'the flip-flop is set so that the time sequence the output pulse o is the same as the time sequence of the input pulses. With the monostable flip-flop, only the pulse time, i.e. the duty cycle of the output pulses, can be varied. Their frequency is clear due to the frequency of the pulse generator given in the controlling device. The amplitude of the Alis gangs impulses is on the other hand constant and independent of the amplitude of the pulses on the measuring line 8.

The output pulses 11 of the flip-flop 10 are adapted in a power amplifier 12 to the given voltage and power requirements of the electromechanical transducers, such as lifting or rotary magnets, used for positioning the construction or components. The power pulses 13 generated are fed from the amplifier 12 to the individual electromechanical converters. Fig. Shows the pulse diagram at the output of the flip-flop or the power amplifier. In Fig. 3, U. ς denotes the device-Vers agungs voltage, U ₁ is the output voltage at the flip-flop, U is the voltage of the power switching pulses.

Heim corresponds to the following closing of the switching element 5, the analog position measuring voltage 8 of the position setting of the voltage divider? and at the output 13 of the amplifier 12 there is a switching pulse which advances the corresponding construction elements of the controlled devices t by one position via an already mentioned selective circuit known per se, if this has detected a non-correspondence with the previous analog output position secondary voltage. Via this selective circuit, so many impulses are passed on to the controlled construction elements until they have reached the position of the controlling component and thus the Üedingixng of the voltage adjustment is fulfilled.

The arrangement can also be made so that the scarf timpul se, which are transmitted via the line 8, to, ;; J α i oh fulfill a measuring task, i.e. that based on the voltage comparison carried out during each pulse, the number of the controlling body to send out pulses is determined.
