Abstract

The invention discloses a dual-mode communication system based on power line carrier and wireless communication. The main processor of the concentrator, the first local communication unit and the remote communication unit, the electric meter includes the main processor of the electric meter and the second local communication unit; the main processor of the concentrator communicates with the first local communication unit and the remote communication unit respectively connected through a serial port; the main processor of the electric meter is connected with the second local communication unit through a serial port. From the point of view of the overall design of the system structure, the invention realizes that the power line carrier communication unit in the dual-mode communication module is fixed as the mother board, and the wireless communication unit is flexible and replaceable as the sub-board, thereby shortening the research and development period and production cost of different broadband dual-mode modules.

Description

technical field [0001] The invention relates to the technical field of short-distance communication, in particular to a dual-mode communication system based on power line carrier and wireless communication. Background technique [0002] Regardless of the power consumption information collection system of the State Grid power user or the low-voltage centralized meter reading system of the Southern Power Grid, the last mile communication technology mainly adopts the power line carrier communication technology. With the continuous expansion of the power grid company's business, many new in-depth application functions have been expanded on the basis of the original system functions, such as: high-frequency acquisition, asset management, phase identification, phase sequence identification, household change relationship identification, power outage event reporting, Multi-table set copying, etc. In particular, the reporting function of power outage events can realize that when the...
