The invention relates to the field of telemetry and can find irieny in the systems for transmitting and processing telemetry information.

Devices for monitoring telemetric information are known, comprising an amplifier-limiter, a subtraction unit, a threshold element with an analyzer, a differential filter, and detectors 1.

Devices for monitoring telemetric information are known, comprising an analyzer, a control and synchronization unit, detectors, a calibration channel selection unit, a switch and an operation unit 2.

Pastor also devices for monitoring telemetric information, containing filters, detector-analyzers, processing unit 3.

The closest to the technical essence of this invention is a device for controlling telemetric information, containing a receiver, one output of which is through a delay element, another output through successively connected reference pulse recovery unit and a gate driver, and switches to the inputs of the comparison unit, the output of the comparison unit through the generator I-mtgulsov errors

connected to the first input of the analyzer, which is connected to the processing unit and the information: And) 1 4.

This device has a number of significant flaws, which are as follows. Firstly, for reI11; In order to change the algorithm and processing unit, it is required to carry out a statistical analysis of a series of errors that occur

does not allow operatively controlling the accuracy of telemetry information, and, consequently, conduct its processing by a sampling algorithm in real time. Secondly, in radio telemetry systems with modulation of VIM-PM (time imimi моду modulation iroi modulation), the iolio telemetry signal also includes a marker signal, which synchronizes both synchronous and normal operation.

I pass on it to her and to the equipment. Distortion of a marker of a telemetric signal, as a rule, leads to loss of information. Within a given switching cycle, this must be taken into account in the process of controlling the accuracy of the telemetry information that is needed.

Gsl 113 of the acquisition consists in the higher efficiency of monitoring the received telemetric information.

This is achieved by the fact that an error isolating unit, an artificial marker driver, a phasing unit and a marker extraction unit, whose input is connected to the third output and receiver, are connected to the device, the output is connected to the first inputs of the phasing unit and the allocation unit. the second inputs of the analyzer and the phasing unit, the output of the phasing unit and the output of the recovery unit of the reference pulses are connected respectively to the first and second inputs of the artificial marker, the output of which is Connected to the second input of the error highlighting block.

The drawing shows a functional diagram of the proposed device, where 1 is a receiver, 2 is a block for restoring reference pulses, 3 is a delay element, 4 is a gate driver, their pulses, 5 is a block compared, 6 is an error pulse generator,

7 - analyzer, 8 - information processing unit, 9 - marker extraction unit, K) - phasing unit, 11 - artificial marker driver, 12 - error extraction unit.

The device works as follows.

The recovery unit 2 generates the recovered reference pulses from the addition of a receiver 1 of the iolithic telemetric signal. The generator 6 compares the received reference Iampuls and the recovered reference pulses in the block 5 compares the error pulses that go to the analyzer 7 to successively check a series of outgoing error pulses and generate control signals to change the algorithm in the processing unit

8information.

The recovered supporting pulses are used by the shaper 11 to form artificial markers phased by a phasing unit with full telemetry signal markers extracted from the receiver 1 signal with the marker selection marker 9. The received and generated markers are iodized to the error extractor 12 to isolate errors such as "false marker and" skip marker. The first type of error corresponds to the case of the allocation of a false marker in the second telemetry signal. A “miss token miss” error corresponds to the case of suppressing a true loop marker in the communication channel by noise. Both in the nerve and in the second cases, decoding of the received and left telemetry signal will be incorrectly wrong, which must be taken into account when processing the telemetry information in this cycle of measurements.

The values obtained for the error selection block 12 using the "false marker" and "skip marker" values are used by the analyzer 7 for the received telemetry signal in the switching cycle so that

Subsequently, when processing telemetry in the processing unit 8, take into account errors when decoding the telemetry signal or attract the recipient of information to them. This allows operatively, at the rate of arrival of telemetry information, to monitor the reliability of the recorded and processed information by identifying the structures of telemetry signals with distorted loop markers.

At the same time, the device, by involving in the assessment of the authenticity of telemetry information, the pulses of the cycle marker, which are part of the polio telemetry signal, makes it possible to increase the volume of the sampling of pulses, according to which the analyzer evaluates the validity of the received information. This increases the accuracy of the control. Thus, by a slight complication of the known

The devices can additionally solve a number of important tasks to increase the efficiency and accuracy of monitoring the reliability of the received telemetric information.
