Abstract

Perfeccionamientos en sistemas de lectura de puntos de conexión, que permiten la vigilancia del estado de los puntos y la señalización de su cambio de estado, que comprenden exploradores cíclicos electrónicos que permiten la identificación y la detección de un cambio de estado de los puntos explorados, caracterizados porque los exploradores son independientes y comprenden medios de detección de estado y de marcado de una señal de pilotaje que indica el mantenimiento de la detección de un cambio de estado durante al menos un ciclo de exploración, y porque el sistema comprende una unidad de control que incluye medios de observación cíclica de los exploradores.
