It is noted that the edge computing server 140 may also be selected before the rfid patch 130 uploads the data to the edge computing server 140.
Illustratively, the rfid patch 130 further includes a server selection module, which is capable of determining a corresponding edge computing server 140 of the substation according to the positioning data uploaded by the environment monitoring device 110.
