ELECTRIC METER NETWORK SYSTEM, ELECTRIC METER NODE AND BROADCASTING METHOD THEREOF |
USA
|
Abstract
An electric meter (EM) network system, an EM node and a broadcasting method thereof are provided. The EM node, which is electrically connected to a power supply loop, stores a layer number and a total layer number. When the power supply loop recovers from a power disconnect condition to a power supplying condition, the EM node obtains a waiting time according to a difference value between the layer number and the total layer number, and broadcasts a route message after the waiting time.

ADVANCED METERING INFRASTRUCTURE NETWORK SYSTEM AND MESSAGE BROADCASTING METHOD |
USA
|
Abstract
An advanced metering infrastructure (AMI) server, an AMI network node, an AMI network system and a message broadcasting method thereof are provided. The AMI server generates a broadcasting key from a broadcasting message through a hash function, encrypts the broadcasting message into an encrypted broadcasting message via the broadcasting key, encrypts the broadcasting key into an encrypted key via a symmetric key, and transmits the encrypted broadcasting message and the encrypted key to the AMI network node. The AMI network node decrypts the encrypted key into the broadcasting key via the symmetric key, decrypts the encrypted broadcasting message into the broadcasting message via the broadcasting key, and processes the broadcasting message after determining that the broadcasting message corresponds to the broadcasting key through the hash function.
