[embodiment]
In order to solve the lower problem of electric network information treatment effeciency, a kind of processing method of electric network data more efficiently and device have been proposed.
As shown in Figure 1, it is the electric network data process method step flow chart of an embodiment, comprises the steps:
Step S01: the ammeter data that reads a plurality of intelligent electric meters through serial ports.
This step is checked meter exactly, copies the ammeter data of getting a plurality of intelligent electric meters, as obtains 4,8,16 even more.
Step S02: a plurality of ammeter datas are packaged into Ethernet data, and add corresponding identification information with it for each ammeter data.
Promptly be that the serial data with the transmission of RS485 protocol communication is changed into the data format that meets Ethernet (Internet) host-host protocol, present embodiment is that a plurality of ammeter datas are encapsulated in two layers of Ethernet message.Said identification information is that this ammeter data of expression is the data of which intelligent electric meter, and it can be a sequence number of distinguishing the different intelligent ammeter.In the present embodiment, this identification information is added in a field of each ammeter data.
