The invention discloses a public
community charging
pile data
concentrator with a dual-network complementary function and an application method of the data
concentrator. The data
concentrator comprises a main control board, an LED (light-emitting
diode) display screen, an uplink communication module, a downlink communication module, a storage module, an intelligent electric meter, a keyboard, an entry and exit
processing module, an LED indication lamp and an equipment maintenance port, wherein the
LED display screen, the uplink communication module, the downlink communication module, the storage module, the intelligent electric meter, the keyboard, the entry and exit
processing module, the LED indication lamp and the equipment maintenance port are respectively connected with the main control board. The data concentrator communicates with charging piles in a
community by a micro-power
wireless module, so that the communication fee of each charging
pile is saved, the communication cost of a whole
electric vehicle operation network is reduced, communication links capable of directly accessing into a background of an
electric vehicle operation
management system are reduced, and the running speed of the background of the
system is increased.
