Abstract

Предложено устройство для высокочастотной мультиплексированной передачи данных по линии электропередач для кабельного телевидения, телефона, Интернет, системы безопасности и других систем управления, передаваемых по линиям электропередач среднего и низкого напряжения и непосредственно через трансформаторы. Устройство включает передатчик, приемник, модем (14), мультиплексор и множество устройств связи (28), в каждом из двух или больше местоположениях вдоль электрической линии (18). Устройства связи имеют емкостные цепи, последовательно включенные с трансформатором (22) с воздушным сердечником или диэлектрическим сердечником. Емкостные цепи включены в цепи резонанса с трансформатором (22) на заданной частоте. Устройство связи (28) устраняет шумы и согласовано с характеристическим полным сопротивлением линии на заданной частоте, что линеаризует передачу данных по линии и позволяет обеспечить высокоскоростную передачу данных и голосового сигнала на большие расстояния. Множество модуляторов и демодуляторов используют для получения множества несущих модулированных частот.Отчет о международном поиске был опубликован 2004.04.08.
