Description

Method and system for upgrading PCS firmware through collector Technical Field The invention relates to the technical field of firmware upgrading, in particular to a method and a system for upgrading PCS firmware through a collector. Background Photovoltaic inverters (PCS) contain an embedded software system, which often requires software upgrades for maintenance or for adding new functionality. Generally, an upgrade process of an inverter upgrade includes steps of starting the upgrade, downloading firmware, message interaction during the upgrade, error processing, data verification, ending the upgrade, and the like. The PCS upgrading method mainly comprises the steps of on-site upgrading, downloading and upgrading new versions through a physical upgrading interface connected with the PCS, wherein the method requires maintenance personnel to go to the equipment site, is high in cost and high in maintenance personnel requirement, and the PCS is remotely upgraded through a collector connected with the PCS, but the method has high requirements on the collector, because PCS in the market is various, even PCS of the same manufacturer has various kinds, upgrading processes, communication protocols and the like are different, the collector is required to develop different firmware for each PCS, the development period is long, the versions are multiple, maintenance and after-sale service are difficult, and if the plurality of PCS upgrades are required to be supported simultaneously, the firmware codes of the collector are inevitably increased, so that the later function is increased or the increase of the new PCS upgrading function is even impossible. Disclosure of Invention In view of the above-mentioned shortcomings in the current firmware upgrading technology field, the invention provides a method and a system for upgrading PCS firmware through a collector, which can rapidly develop a PCS firmware upgrading program under the condition of not updating the collector firmware, and complete the remote upgrading of PCS together through the cooperation of the collector and a PCS cloud upgrading service platform, thereby reducing a large number of development periods and collector firmware codes and enabling maintenance and after-sale service to be simpler. In order to achieve the above purpose, the embodiment of the present invention adopts the following technical scheme: The method for upgrading PCS firmware through the collector comprises a PCS cloud upgrade service platform and the collector connected with the PCS cloud upgrade service platform, wherein the PCS cloud upgrade service platform comprises a PCS firmware management module, and the collector comprises an upgrade program interpreter and a firmware upgrade control module and further comprises the following steps: s1, acquiring an upgrade protocol document of a PCS, and writing an upgrade program on a PCS cloud upgrade service platform according to the upgrade protocol document; s2, uploading PCS firmware to a PCS cloud upgrade service platform through a PCS firmware management module, and designating an upgrade program to be used; S3, sending an upgrade command to the collector through the PCS cloud upgrade service platform; S4, downloading PCS firmware and an upgrade program to a local storage space of the collector through a firmware upgrade control module, and running the upgrade program through an upgrade program interpreter by an upgrade command; S5, finishing the updating of PCS firmware, and exiting the updating flow by the collector.
