A METHOD FOR DETECTING AN OPEN CIRCUIT SUCH AS PUBLIC LIGHTING SYSTEM

摘要

A method for detecting an interrupted circuit, with the circuit being of the type including a plurality of electric loads connected to an electric line (L) and powered by a supply and control apparatus (1), each electric load including a using element and an auxiliary device, arranged in parallel, includes: the transmission, on the electric line, of at least one first control signal (S(i,i+1)) from a first auxiliary device (Di), connected to a corresponding first load (Ci), belonging to a plurality of electric loads, to a second auxiliary device (D i+1), connected to a corresponding second electric load (C i+l), adjacent to the first load (C1), belonging to the plurality of electric loads; the receiving of the first control signal (S(i,i+l)), transmitted by the first auxiliary device (Di), by the second auxiliary device (D i+1); the transmission of a first error signal (Err (i+1,(i))) to the supply and control apparatus (1), by the second auxiliary device (D i+1), which indicates the lack of the first control signal (S(i,i+l)) directed to the second device (D i+1).
