The invention relates to telemetry and can be used to collect information with automatic decoding of measurement results.

The purpose of the invention is to expand the field of application by providing reception of different polarity signals.

The drawing schematically depicts the present device. My device.

The device comprises a playback unit 1, a selective filter 2, a detector 3, a recording unit 4, And 5 elements, a synchronization block 6, an adder 7, a multiplication unit 8, a memory block 9, an additional And 10 element and a BAN 11 element.

The device works as follows.

The signal from block 1 at the first output is successively fed to the selective filter 2, detector 3 and block 4, which respectively select, record and record the calibration signal determined (oh frequency and amityta).

The code information from block 1 via the second outputs, the number of which is determined by the number of code bits carrying information, goes to the first inputs of the And 5 elements. To the second inputs of the elements and to the first inputs of the elements 10 and 11, pulses are received from block 6 TaKTOBiiie which it is advisable to set equal to the frequency of the digital words telemetry frame. Block 6 is a conventional pulse generator. At the same time, the value of each digit of the current digital word is read, summed B from the adder with the corresponding weight of the digit. From the additional output of unit 1 to the second inputs of elements 10 and 11, a signal is received that carries information about the sign of the telemetry parameter in the digital word. For example, the negative value of the parameter in the digital word corresponds to the code “1 in the symbol-m digit de positive — respectively, the code“ O. Thus, at the output of the adder, the absolute numerical value of the digital word N of significant bits is obtained, which in block 8 is converted into physical

This is the value of the parameter Y and is recorded in block 4 with the appropriate sign. The value of Y is determined by the formula

Y L-K-N,.

where K is the price of the least significant parameter value in physical terms. The values of K for various codes are stored in the memory of block 9; L is the value of the sign bit determined from the condition: (1 - if the value of the parameter Y in the digital word is positive; -1 - if the value of the parameter Y in the digital word is negative. From the output of block 8, the encoded absolute value of the measured value arrives at the second input of block 4, to the third and fourth input of which from elements 10 and 11, depending on the value of the sign bit of the digital word currently being recorded, the signal that determines the positive (from element 10) or negative (from the element11) the field for recording the values of the measured parameters Y in physical quantities in block 4.

In this way, in the proposed device, the telemetry code is cleared of a two-pole measurable value into engineering units, which excludes the manual labor associated with deciphering the measurement results from the processing process.
