Product Overview:

    Acquisition unit Ⅱ( carrier wireless dual-mode), a power line narrowband carrier and micropower wireless dual-mode communication acquisition unit, is independently developed in accordance with the State Grid Enterprise Standard Q/GDW-2013. The narrow-band carrier of power line and CN470MHz/EU868MHz/AS923MHz micropower wireless are used as communication medium to communicate with the remote concentrator, and RS485 is used to communicate with the electric meter, so as to realize the centralized meter reading by the concentrator to the local electric meter,and solve the weak transmission problem in blind area.It has the advantages of long communication distance, strong anti-interference ability and easy to use.
