Method of measurement of the values of at least one entry evolving in the time of repetitive manner, with monitoring thresholds a variable levels

摘要

The invention relates to a method of measurement of the values of at least one entry evolving in the time of repetitive manner, during successive periods, with monitoring thresholds a variable levels / p & & p & this process consists in converting, for each measurement period, an analog signal representative of the evolution of the values of this entry,] the values of c and to record these values]. The method also consists in recording] the reference values obtained by sampling the analog, during the measurement periods for which the values of the entry of desired evolve. It compares the values] a has a measurement with the values of reference], for trigger an alarm or a control value, 1984, when at least one measurement c exceeds the corresponding value of reference, a predetermined or calculated by a function program. / p & & p & application in particular to the monitoring of debits of water courses.
