Claims

The output of the pulse generator 1 is connected via a voltage converter 2 to the input of a multichannel sensor displacement 3, the outputs of which are connected via series-connected delay elements 4, inverters 5, elements AND 6, element OR 7, differentiating unit 8 are connected to the input of reading unit 9, from the elements of And, the outputs of which are connected to the input of the bits of the counter pulse 1O. Other inputs of elements And 6 are connected to the outputs of the channels of the multichannel displacement sensor 3. The counting input of the pulse counter 1O is connected to the output of the pulse generator 1, and the reset input of the pulse counter 10 through the reset element 11 is connected to the output of the differentiating unit 8. The outputs of the reader 9 connected to a recording device. The operation of the device is as follows. Pulse generator 1 generates pulses of a stable frequency AND (see Fig. 2) The power supply voltage converter compresses the supply voltage of the multichannel displacement sensor 3. The sensor channel number can be any. The operation is illustrated by the example of a three-channel sensor. The output of the multichannel sensor Potentials are displaced by 1 or O depending on the spatial phase, i.e. the position of the sensor signal windings relative to the moving rotor winding in the case of using multiphase inductosin as a lot channel sensor displacement. For the operation of the proposed device, the sensing elements and elements specifying the displacement should be displaced so that the sequence of pulses at the output of the multichannel displacement sensor are mutually displaced by the value T (ii) (where T is the pitch P L is the the channel number is a multiple of the number of channels P. When the rotor rotates the multichannel displacement transducer 3 at a certain speed W, the output of the three-channel displacement transducer is pulses I, AND, AND (see FIG. 2) shifted to a value proportional to - / 3. At the output of the delay elements, the pulses are delayed by the amount of Toi which is necessary to form short pulses. Inverter delayed pulses And, as shown in FIG. 2 for the first channel, receive signals of the type AND, which, when operating a logical multiplication with signals AND arriving at the other input of element 6, form short pulses AND, Summing these pulses on the element OR 7, we have a sequence of pulses AND AND,. And And - and - Of. and oos5 In differentiating unit 8, pulses I-are emitted, on the leading edge of short pulses, at the moment of which the code of pulse counter 1O is taken from reading unit 9. The pulse counter 10 is filled at times between successive counter drops to zero, which is carried out using the reset delay element 11. As the pulses on the reset delay element come from the differential unit 8 with the pulse frequency of the multi-channel displacement sensor 3, which is proportional to the speed of movement the moving part of the multichannel displacement sensor 3, then the pulse counter 10 is filled during the time interval between pulses AND (see FIG. 2), inversely proportional to speed of movement, and its reverse code, removable at the moment of time corresponding pulses Ip in the recording unit 12, proportional to the movement speed.
