The research of eliminating uplink communications blind area in Low-voltage Meter Reading System
The power information collection equipments which would be installed in mobile signal blind area, where the GPRS 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 base on wideband carrier communication technology, called broadband carrier wireless signal repeater. This repeater is composed by a master node and a slave node. The master node always locate at good signal areas, while the slave node is installed in the data concentrator, they can communication with each other through the broadband carrier. SExperiments show that broadband carrier wireless signal repeater has a good performance on communication and reliability, which can meet the demand of intelligent electricity consumption and electricity information acquisition system.
