Intelligent charging pile networking system adopting broadband power carriers

Abstract

The invention provides an intelligent charging pile networking system adopting broadband power carriers, and relates to the technical field of communication of charging piles with video advertisement functions. The intelligent charging pile networking system comprises a distribution box and multiple groups of charging piles, the distribution box comprises a power distribution control unit and a main carrier module, the power distribution control unit and a power supply end of a main carrier module are separately connected to a power line, and a signal end of the power distribution control unit is connected to the power line through the main carrier module; the main carrier module of the electric carrier high speed communication technology is installed in the distribution box and is connected to all slave devices in the charging pile groups by power lines, the communication is realized by the power lines, and no additional wiring is required; and the main carrier module works as a connecting link between the preceding and the following in the whole network: uploading the information of a slave carrier module to the main carrier module through the power line so as to realize the communication between the main and slave carrier modules.

Description

technical field [0001] The invention relates to the networking technology of charging piles, in particular to the field of communication technology of charging piles with video advertising functions. Background technique [0002] There are currently five charging pile networking solutions: GPRS DTU, RS485, CAN, Ethernet, and WIFI. Using GPRS DTU to network charging piles generally has disadvantages such as unstable communication signals, low transmission rate, poor anti-interference ability, and high cumulative traffic costs; using RS485 and CAN to network charging piles, although the equipment cost is low, but needs Laying dedicated communication cables, half-duplex transmission mode, with the increase of the number of nodes and transmission distance, the communication rate drops rapidly, and the total cost is relatively high; using Ethernet to network charging piles, the cost of integrated wiring is high, and the workload Large, each pile group needs at least one multi-po...
