Problems solved by technology
However, although the module using HPLC communication technology has excellent performance, it has the disadvantages of high cost and high power consumption due to the use of broadband carrier communication between the meters in each meter box, as well as between the meter and the concentrator.
The high cost leads to slow promotion, and the high power consumption is not conducive to energy saving

The invention relates to an electricity consumption information acquisition system, which comprises a concentrator and two or more than two meter boxes; each meter box comprises two or more than two electric meter units; the electric meter units in each meter box are communicated through wireless transmission, each electric meter unit in each meter box comprises a main electric meter unit, and themain electric meter unit in each meter box is in broadband carrier communication with the concentrator through a power line. Wireless communication and an actual power consumption information acquisition scene are combined, data acquisition is carried out on a short-distance electric meter in a meter box through a wireless communication technology, a wireless signal is converted into a broadbandcarrier signal throughthe main electric meter unit, and the broadband carrier signal is transmitted to a far-end concentrator through a broadband carrier communication technology. Only one main electric meter unit needs to be used for broadband carrier communication in each meter box, and other electric meter units can realize data information acquisition by adopting a wireless communication technology, so that the cost and the power consumption are greatly reduced.
Description
technical field [0001] The present application relates to the technical field of electric power grids, in particular to a power consumption information collection system. Background technique [0002] The State Grid promotes a strong smart grid strategy. As an important part of the smart grid, the power consumption information collection system must realize "full coverage, full collection, and full cost control" for power users. Power Line Carrier (PLC, or Power Line Carrier) is a communication method that transmits voice or data through power lines. The biggest feature of this communication method is that no additional network is required, and only existing power lines are needed to transmit signals through carrier waves. way for high-speed transmission. [0003] At present, broadband power line carrier communication technology (HPLC communication technology) is gradually promoted in various regions, using power lines as the transmission medium, and using broadband carrier...
