Description

The device relates to the field of information transmission and can be used in adaptive multichannel digital telemetric systems as an encoder.

Devices are known for processing and transmitting information in the multichannel digital telemetry systems, in which an increase in the message transmission rate is achieved by using special code combinations defining the number of identical information code blocks containing a synchronizer, a memory block, a signal analyzer, coding blocks. measuring information

Known devices are not high enough speed.

The aim of the invention is to increase the speed of information transmission without extending the signal spectrum, i.e., improving the speed of the device.

To do this, enter the E. Chemeit IE, Element I device, the coding block of the channel marker marker and the delay element whose input is connected to the output of the encoding measuring information bit, the output of the delay element and the output of the Sigia.Yyv node of the target. than the RT, the output of which is connected to the second entrance of the b. yuka buffer | ZoG | memory whose BTOpoii output is NOT connected to the third input of the correlation moment pairs analysis unit, the second output of which is connected to the third input of the channel address coding block and connected to the OR element via the coding block of the marker. The drawing shows a functional diagram of the device for processing and transmitting information. It contains synchronizer 1, channel switch 2, measurement information coding unit 3, signal analyzer 4, multichannel memory block 5, AND 6 element, delay element 7, buffer memory block 8, correlation moments analysis block 9, coding block 10 channel addresses, NOT element 11, channel group marker coding unit 12, element OR 13, time encoding unit 14. The operation of the device is as follows. The signals of the synchronizer 1 control the operation of the switch 2 channels, by means of which the signals of all L channels are input to the input of the measurement information coding unit 3. The coding unit 3, in accordance with the amplitude of the input signal, generates a code combination in the form of a parallel double code. Code combinations are provided to the inputs of the signal analyzer 4 and the multi-channel memory unit 5. From the output of block 5, a code combination is simultaneously removed, displaying the value of the source channel of the given channel at the point of reference preceding the one under consideration and spaced by a time equal to the duration of the sampling (iridation) TO period. Analyzer 4 compares the i-th and (i-1) -th sample values, expressed as code combinations. If the absolute value of the difference between the two values exceeds the quantization step but the level, then the output of the analyzer 4 but is the control signal, the opening element AND 6, and the current code combination does not arrive at the input of block 3. After the termination of the analysis of the (-i) and (/ - 1) -th channel samples from the output of synchronizer 1, the block 9 for analyzing pairs of correlation moments receives a signal to allow the output of the comparison of code combinations of signals between the combinations of channel pairs L. At each sampling period Possible direct code combinations of the 1st channel are compared with all combinations of the remaining channels. With the presence of the given code combination of the 1st channel in any other channel numbers from block 9, signals for encoding the addresses of the channels to which this code combination belongs are sequentially output to the channel address coding block 10. After wrapping up 6403 5 10 15 20 25 30 35 40 45 50 55 50 65 compares the informational direct code combination of the 1st channel with all subsequent channels, from the other output of block 8 through the element NOT 11 to the input of block 9 is inverted the same combination, where The detection of subsequent channel iomers, through which the information code combines coincide with the inverse information combination of channel 1, is occurring. In the presence of such coincidences, block 10 receives signals for the formation of codes for the number of channels, available1, their information codes that coincide with the reverse code of the 1st channel. In addition, the signal of the first match in the specified channel group enters the block 12 to form a marker of a group of channels having information code combinations that match the reverse code of the 1st channel. The presence of the marker code between the soil of the channel addresses on the receiving side allows information copying the code combination belonging to the corresponding channels. Upon completion of the formation of the address code of the last channel included in this group, from the output of block 10, the block 8 of the buffer memory receives a read signal of the direct information code combination of the 1st channel, which, following the address codes of the channels separated by a marker, and corresponding to this direct and inverse combination, through the element OR 13 nostunat to the output device. In the absence of information code combinations, which coincide with the inverse code combination of the 1st channel, the code of the marker and the second group of codes of addresses of the channels are not received at the output of the device. And in the absence of a direct code combination in the remaining channels, in block 10, the channel address is encoded, a signal is generated to form the address code of only the 1st channel, and the measuring code combination is mixed into the address code by the above method. Then, the analysis of the code combination of the 2nd channel (if it was used in block 8 of the buffer memory, i.e., it is meaningful and did not match the forward or inverse code combination of the 1st channel) with the code pattern combinations of the remaining L-2 channels, and so on. At the beginning of each telemetry frame from time encoding unit 14, a current time code combination is supplied to the device output. As can be seen from the operation of the proposed device, the duration of telemetry frames can be reduced and, therefore, the transmission rate of messages is increased by excluding from the frame the information code combination belonging to the next channel (channel group) and the previous channel (group channels).
