Abstract (en)
Procedure for detecting breakdowns in street lighting typified because it consists of detectors, an emitter and the lighting lines themselves, connecting a detector to each light, as each detector consists of sensors capable of controlling the principal parameters of the line, each detector possessing an identification code that can be programmed, because the emitter is compatible with the information contained in the detectors during the functioning of the lights, making it available from a unit of connection and the whole being designed in such a way that, for example, with a Master/Slave system of questions and replies the emitter emits questions according to the codification of directions which the detectors decodify, being the detector the direction of which coincides with that transmitted which responds for the state of the lighting under its charge.
