DEVICES, SYSTEMS AND METHODS FOR UPGRADING FIRMWARE IN INTELLIGENT ELECTRONIC DEVICES

摘要

The present disclosure is directed to devices, systems and methods for upgrading firmware in intelligent electronic devices (IEDs). The present disclosure provides for checking a remote server for updates for one or more firmware packages installed on an IED and determines if an update is available for the one or more firmware packages installed on the IED. If an update for one or more packages is available, the update is downloaded and installed on the IED. The update of the package may be automatic or initiated by a user.

主权项

1. An intelligent electronic device (IED) comprising:
at least one sensor configured to measure at least one parameter of an electrical distribution system and output at least one analog signal indicative of the measured at least one parameter; at least one analog-to-digital converter configured to receive the output signal and convert the output signal to a digital signal; at least one processor configured to receive the digital signal and calculate the least one power parameter of the electrical distribution system; at least one memory including a first package list including packages currently installed on the IED; and at least one communication interface coupled to a network, wherein the at least one processor is configured to update the packages installed on the IED by:
sending a request via the at least one communication interface to a server coupled to the network, the request requesting a second package list stored on the server including available updates for packages stored on the IED,receiving the second package list from the server via the at least one communication interface;comparing the first package list to the second package list;determining if there is a newer version of at least one package installed on the IED that is available for download from the server based on the comparison of the first package list to the second package list;downloading the newer version of the at least one package from server via the at least one communication interface if it is determined by the at least one processor that there is a newer version of the at least one package available; andupdating the at least one package to the newer version of the at least one package.
