Patent ID: 8682618

Claim:
A data transmission system for remote logging, the system comprising: a measurement sensor, comprising an electronic circuit with a non-synchronized internal clock and a memory for storing at least one value measured at a first time (t 1 ) of the internal clock, and a transmitter configured to transmit, at a second time (t 2 ) of the internal clock, the value or values measured at the first time (t 1 ), and a receiver synchronized to a reference time base for gathering the transmitted measured values, wherein: the sensor comprises an electronic circuit configured to establish the time difference Δt=(t 2 −t 1 ) between the times of transmission (t 2 ) and of measurement (t 1 ) according to the internal clock of the sensor, and the transmitter being further configured to transmit, with the value or values measured at the first time (t 1 ), this time difference Δt, and the receiver comprises a circuit configured to subtract from the time of reception (T 0 ), according to the reference time base, the time difference (Δt) transmitted by the transmitter in order to give the difference (T 0 −Δt) between the time of reception (T 0 ), according to the reference time base, and the time difference (Δt) between the transmission and the measurement as a time stamp to the transmitted measurements.
