METHOD FOR TRANSMITTING TELEMETRIC INFORMATION Russian patent published in 2021 - IPC G08C19/28 

FIELD: data transmission.

SUBSTANCE: invention relates to data transmission systems and can be used in telemetry systems with cyclic polling of the controlled parameters. The method consists in the fact that the signals are collected on the transmitting side from the measuring sensors including sensors of rapidly changing parameters (RCP), converted to binary, synchronisation of the formed measurement words represented by an N=2n-bit binary code, is ensured, and a multiplex digital group signal is formed from said measurement words, subject to transmission via communication channels, and the resulting sequence of the transmitted binary symbols is received on the receiving side. The code structures formed at the first stage of encoding measurement words or messages are represented on the transmitting side as remainder images of b_1j(mod m₁) and b_3j(mod m₃), obtained as a result of operations equivalent to dividing the discrete values X_j thereof selected for transmission at times t_j=jΔT, wherein ΔT is the time sampling interval defined in accordance with the V. A. Kotelnikov sampling theorem, by the established comparison modules m₁=2ⁿ-1 and m₃=2ⁿ+1. The obtained results of additional encoding of the initial values of X _j by the remainder images b _1j(mod m₁) and b _3j(mod m₃) are combined into new code words so that the capacity thereof and the telemetric frame structure remain the same. In order for the conditions of reception and collection of telemetry information (TMI) to remain unchanged, the transmitted telemetry frames with the established external structure S_ext are restored while receiving the TMI, wherein additionally encoded new measurement words as applied to the RCP data are isolated from said structure, distorted during transmission by ε_1j and ε_3j interference, followed by interference-resistant recovery thereof providing a reduction in the intensity of the interference influence and therefore an increase in the indicators of accuracy of reception of TMI.

EFFECT: ensured interference-resistant encoding of rapidly changing parameters (RCP).
