Apparatus, system and method for upgrading firmware of energy metering device

摘要

An apparatus, system, and method for upgrading firmware of an energy metering device are provided. A method for upgrading firmware of an energy metering device which receives firmware from a server via a network and upgrade firmware includes: transmitting a size of a firmware segment to the server, initializing firmware upgrade, receiving a firmware segment from the server, and controlling the energy metering device to operate with received firmware in response to a request for activating firmware from the server. The server communicates with the energy metering device by using an object model obtained by object-modeling the size of a firmware segment, the firmware segment download, and the activation request.

1. An apparatus configured to upgrade firmware of an energy metering device in a system including a server, the apparatus comprising:
a communication unit configured to communicate with the server over a network, using firmware upgrade information including a plurality of object oriented data models, wherein each of the plurality of object oriented data models are classified by a corresponding logical identifier which is determined by a function according to the upgrade firmware to be implemented by the energy metering device such that the plurality of object oriented data models, which are associated with the same function according to the upgrade firmware, have the same logical identifier, at least one storage unit; and a controller configured to:
receive a first object oriented data model, a first object of the first object oriented data model representing asking the size of firmware segment the energy metering device is able to receive at a time from the server and a second object of the first object oriented data model representing the logical identifier,send a second object oriented data model, a first object of the second object oriented data model representing the asked size of the firmware segment and the second object of the second object oriented data model representing the logical identifier,receive at least one firmware segment to the energy metering device based on the asked size of the firmware segment,receive a third object oriented data model, a first object of the third object oriented data model representing the server's order to start firmware upgrade and a second object of the third object oriented data model representing the logical identifier,send a fourth object oriented data model, a first object of the fourth object oriented data model representing a status of starting the firmware upgrade in response to the received server's order and a second object of the fourth object oriented data model representing the logical identifier,send a fifth object oriented data model, a first object of the fifth object oriented data model representing a status of the firmware upgrade in progress, a second object and a second date item of the fifth object oriented data model representing the logical identifier,send a sixth object oriented data model, a first object of the sixth object oriented data model indicating completion of the firmware upgrade and a second object of the sixth object oriented data model representing the logical identifier, andoperate the upgraded firmware when the server transmits a seventh object oriented model, a first object of the seventh object oriented data model representing the server's order to activate the upgraded firmware and a second object of the seventh object oriented data model representing the logical identifier.
