低压电力集抄上行通信信号盲区解决方案研究
Research on eliminating uplink communications blind area in low-voltage meter reading system
摘要
Abstract
The power information collection equipments which would be installed in mobile signal blind area , where the GPRS/CDMA communication modules are off-line, in such a situation, the communication will fail.In order to resolve this problem , after analyzing the advantages and disadvantages of the existing solutions , this paper introduces a new solution which is based on wideband carrier communication technology , called broadband carrier wireless signal repeater .This repeater is composed by a master node , a slave node and data conversion unit .The master node always locates at good signal areas , while the slave node is installed in the data concentrator , and they can communication with each other through the broadband carrier .Experiments show that broadband carrier wireless signal repeater has a good performance on real-time communication and reliability , which can meet the demand of intelligent electricity con-sumption and electricity information acquisition system .关键词
