Beschreibung
Zusammenfassung:	A safe and remote wireless meter reading and charging system comprises smart meters, data collectors, coordinators and a management system, wherein each coordinator creates a wireless network with an independent network identity, the corresponding data collectors join the network, each smart meter selects one group of key and encryption algorithm (A) randomly from a key and encryption algorithm matching table, first encryption is performed on power utilization information, a power utilization information frame is generated, the corresponding data collector performs second encryption on the power utilization information frame to generate a new power utilization information frame and sends the power utilization information frame to the corresponding coordinator, and the power utilization information frame is resent if the corresponding data collector receives a resending request frame and analyzes that the network address of the data collector is contained in the frame; the management system monitors a time slo
