Increasing the number of channels (and sensors) when using known devices (systems) leads to complication of all equipment (specifically, when using these telemechanics devices) must be equal to the number of functional transducers of the transmitter, the number of differentiating chains, the number of output drivers, which greatly complicates the design of the entire apparatus). ,

The aim of the invention is to increase the informativeness of the telemechanical system.

FIG. 1 depicts a telemechanical system; Fig. 3 shows voltage diagrams explaining the operation of the transmitter; Fig. 4 shows voltage pulses in the communication line.

The telemechanical system (Fig. 1) on the transmitting side contains a gene & 1 sinusoidal voltage transmitter, transmitters 2-2 liters, each of which contains sensors 3 and 4, functional transducer 5 differentiating unit 6, output driver 7 pulses, link 8 , on the receiving side, containing signal selectors 9, functional converters 10, additional AND signal selectors, polarity reversal units 12 Functional converter 5 contains first and second diodes 13 and 14, resistors. 15 and 16, the third and second inputs 17 and 18 of the converter 5 with the output 19, the second terminal of the resistor 16 is the first input 2 of the converter 5. The health and synphonization of the ground M and the transmitter are connected to the jog voltage of the alternating voltage rahfeaepitele (obvedeshugo figure 1 1 fever by a line with dots on the right). The distribution receiver’s receiver strut includes a selector 11, two blocks 12 half-rounds and selectors 9. Selectors 11 that are designed for waving rectangular impulses from half-wavelength sinusoidal voltage can be easily implemented using oranzistornyh keys, relays, as well as one-half wavelengths straighteners. In this case, one selector 11 is a negative pulse selector (i.e., this selector responds only to negative negative half-waves with sinusoidal voltage and feeds negative rectangular pulses at its output. The other selector 11 triggers positive pulses (i.e., it responds Only positive half-waves of sinusoidal voltage form positive rectangular pulses at their output.) Blocks 12 polarity reversals, intended for normal polarity of pulses, can easily & Each of the selectors 9 is connected in the form of a logical element of a conjunction (two-input) with two inputs (i.e., this element performs a logical operation. At the same time, the selectors 9 (conjunctors) of the primary) and from the top and of the channels positive, impulses (i.e., they respond only to positive impulses at their inputs), and selectors 9 of the third and fourth channels have negative impulses, i.e., they respond only to negative impulses at their inputs. The proposed system works cl & blowing way. Transmitters.2 -22 differ from each other only in that their formers 7 form signals of different polarity, i.e. one in the form of positive impulses, and the other in the form of positive pulses. Consider their work on the U) transmitter operation 2. A sinusoidal voltage with amplitude VQ (curve 21 in FIG. 3) from the sinusoidal voltage generator 1 is fed to the second input of the functional converter 5. A useful signal from the sensor 3 is supplied to the third input of the functional converter 5. A useful signal is supplied to the input of the functional converter 5. the signal from sensor 4. Functional u in the imaging body 5 works as a two-way dio; The {limiter with two variables, ypOBHsiMH, in which the fields and signals of sensors 3 and 4 determine the level of the restrictions. A crawl after a two-sided diode limiter — a functional transducer 5; the base has a curvature 22 (FIG. 3), where T is the period of the sinusitis generator voltage; &Apos; is the duration (i.e., time) for which the voltage at the output of the functional pre-phaseer varies in a sine wave between 0 and the voltage value V2. For example, $ 1 1: the output from the function of functionalizer 5 is transferred to block 6 (in a vice RC circuit or differentiating amplifier). After that, the voltage has the form of pulses 23 (Fig. 3), the duration is determined by the values 2jj and r and depends on the levels limitation The bipolar pulses 23 are fed to the input of the output driver 7 (full in the form of a key or a relay), which re-enters only positive pulses are 23. From the output of the output shaper 7, rectangular 24, whose durations are determined by durations 2 and L (useful signals), are sent to the receiver via a communication line. Separately, the lengths L and i cannot be greater than the value of jj (a quarter of the period of the sinusoidal voltage of the generator). Thus, the time channel (one) in the communication line (kai transmitter output) is equal to the duration / 4 (i.e. a quarter of the sinusoidal voltage period). Pe1: retrieval of information over the communication line is carried out using the time of pulse 1 modulation (2 is the signal of the first canal {L, .- signal of the second channel). The transmitter 22 (second) works in much the same way as the first one, but its special feature is that the output driver 7 of the pulses of the transmitter 2 responds only to negative pulses from the output of the differentiating unit 6, resulting in negative signals from the output of the second transmitter impulses 5 (Fig. 4) with durations of 6 and 14 (i.e., signals of the third and fourth channels). The communication lines (Fig. 4) transmit signals on four time channels (signals and and r from transmitter 2 ,,, (signals LI and t / i from transmitter l., L, L, L and signals from transmitter 2:. . -, at the same time, the duration of each time channel is equal to a quarter of the period T. The signal going through the four time channels is transmitted over the communication line from the transmitter to the receiver (to the receiver distributor). The receiver distributor of the proposed system separates (distributes) signals of different time channels along the corresponding spatial channels (receiver chains. С synchronization and synchronization of the transmitter and the receiver are carried out with the help of this distributor. With a positive half-wave of sinusoidal voltage, a signal of a positive half-wave (in the form of simultaneous rectangular pulses) appears at the first inputs of the input separators 9 of the second and fourth channels, at the first inputs there are no other selectors 9 of the signal, since it is not passed by the first selector 11, which reacts only to negative voltage half-waves. In the case of a positive half-wave from the mt RI of the connection, there are 5 g signals only 12 and d (Fig. 3 and 4), which are selected with the corresponding selectors 9 of the second and fourth channels. In the case of a negative half-wave voltage of the generator, its signals in the form of rectangular pulses are allocated at the first inputs of the first and third selectors 9, the second inputs of which in this case. – G.,. - signals c and i from the communication line are in effect, as a result of the first and the third nrrOTJT R HLN.CHGPiT YARO TATPIKYT AND TOBTII selectors 9 select signals t, respectively, from their outputs (and from the selector 9 outputs rectangular constant pulses the amplitudes of the constant period of the Tis varying outputs (t are fed to the corresponding converters 10, the outputs of which generate sinusoidal voltages of doubled frequency, the amplitudes of which are the output signals of the system. In the proposed telemechanical system, if its simplicity is The four channels are achieved, i.e., the possibility of telemechanical transmission of signals from four sensors, which increases its information content.
