Abstract:
1. An electric meter (EM) network system, comprising: a back-end server; a concentrator communicatively connected to the back-end server; a first EM node electrically connected to a power supply loop, being configured to store a first layer number and a total layer number, wherein when the power supply loop recovers from a power disconnect condition to a power supplying condition, the first EM node obtains a first waiting time according to a first difference value between the first layer number and the total layer number and broadcasts a first route message after the first waiting time; and a second EM node electrically connected to the power supply loop, being configured to store a second layer number and the total layer number, wherein when the power supply loop recovers from the power disconnect condition to the power supplying condition, the second EM node obtains a second waiting time according to a second difference value between the second layer number and the total layer number and broadcasts a second route message after the second waiting time; wherein the first waiting time is longer than the second waiting time, the first EM node receives the second route message from the second EM node and broadcasts the second route message after the first waiting time, and the concentrator receives the first route message and the second route message from the first EM node.
