Referring to fig. 4, a schematic flow chart illustrating steps of another data processing method according to an embodiment of the present application is shown, which may specifically include the following steps:
s401, a main control unit receives power data collected by a distribution network automation feeder terminal and sends the power data to a digital signal processing unit;
the method can be applied to the RDSS communication terminal shown in fig. 3, and the communication terminal can include a big dipper RDSS antenna unit, an RDSS radio frequency signal combining unit, an RDSS radio frequency signal processing unit, an RDSS digital signal processing unit, a main control unit, a big dipper RDSS logic processing unit, a power supply unit, and the like.
