An Automatic Meter Reading System Based on Integrated Carrier and Power Frequency Technology
摘要
Abstract
Low- voltage power line carrier channel attenuation, interference and random dynamicity make the carrier communication can not satisfy automatic meter reading system whole collection and coverage construction requirements.TWACS also transmits signal by power line, and uses the 50Hz power frequency signal as its carrier frequency, which is not conflictive with the 3 ～ 500kHz carrier communication frequency range. Based on the long transmission distance,high communication reliability and low cost of TWACS, this paper realizes a mixing network composed of carrier and power frequency communication without any additional equipment. Then the system implementation of concentrator and acquisition terminal is discussed, aiming at the given networking scheme. The field test proved that the system effectively solves the carrier communication blind spot problem, with high reading success rate and good communication effect.关键词
