Abstract

The invention provides a remote upgrade method based on broadband carriers. The method comprises the specific steps that S1, a concentrator acquires an upgrade file of a remote device; S2, the concentrator selects an upgrade mode according to a configuration file; S3, the concentrator starts an upgrade process to perform remote upgrade; S4, remote broadband carrier modules judge whether the remote upgrade is specific to themselves or other devices connected with themselves according to a received starting frame; S5, after the concentrator starts the upgrade process, the upgrade file is transmitted segment by segment according to 512 bytes per segment; S6, the remote broadband carrier modules judge whether the received upgrade file is complete after receiving an ending frame; S7, the concentrator regularly queries file receiving records of all the remote broadband carrier modules and retransmits failed data packages till success; and S8, the remote carrier modules judge a file device type code after receiving the correct upgrade file.

Description

technical field [0001] The invention relates to the technical field of low-voltage power carrier communication, in particular to a remote upgrade method based on a broadband carrier. Background technique [0002] At present, the country is vigorously promoting the construction of smart grids, and low-voltage power line carrier communication has been widely used in centralized meter reading systems. With the construction of the smart grid, the scale of the acquisition system becomes larger and larger, and the subsequent maintenance workload of the system is also increasing, and the maintenance cost is also increasing. Since the acquisition equipment does not support remote upgrades, maintenance personnel can only search for equipment to perform local upgrades, resulting in low work efficiency. At the same time, equipment without remote upgrades is difficult to meet the new business needs of the State Grid Corporation of China, thus limiting the expansion of collection servic...
