Abstract

The invention discloses an electric power data acquisition method based on a power line carrier technology in the technical field of electric power data acquisition. The method comprises the steps ofinstalling a collector on an electricity consumer terminal; obtaining the power data, carrying out spread spectrum processing on the acquired power data, using a modulator embedded with a sub-channeladaptive selection algorithm to modulate the data, and transmitting the data to a coupling unit, using the coupling unit with impedance to couple the power data to a power line, transmitting the powerdata to a concentrator through the power line and a repeater, using the concentrator to send the power data to a main unit through a GPRS transmission unit; using the main unit to demodulate the power data; and classifying and storing the demodulated power data in a big data background through the main unit and a data processing unit. According to the invention, a frequency band adaptive scheme is adopted, the anti-interference capability is improved, the anti-interference capability of an existing modulation mode is improved by combining a spread spectrum technology and an OFDM modulation mode, and the reliability of the electric power data acquisition is improved.

Description

technical field [0001] The invention relates to the technical field of power data acquisition, in particular to a power data acquisition method based on power line carrier technology. Background technique [0002] In the power line carrier meter reading system, the collector is a control device used in the power system, and its position is between the electric meter and the concentrator, that is: electric meter-collector-concentrator. The collector has three main functions: collecting meter data (such as peak, trough, and flat data at different time periods), saving, uploading data through the power carrier response to the concentrator's command, or transmitting commands to the meter (such as the meter can cut off the user's electrical function). At present, residential buildings are generally installed with centralized meters, that is, the meters of each household are neatly installed side by side. For this kind of centralized meter installation, a collector can be used t...
