Abstract

The invention discloses a data processing mechanism of a photovoltaic power station data collector in an off-grid state, and relates to the technical field of electric power data collection. The invention mainly includes the following steps: system initialization; collecting inverter data and maintaining communication with the platform; data storage and transmission. The present invention stores data information when the network is disconnected, adds time information to each frame of data; sets a data upload time period when historical data is uploaded, selects the state network platform server to upload historical data when it is idle, and reduces the burden on the platform; sets the number of data uploads, and the sending is successfully stopped Send, send failed, try to send multiple times, prevent historical data from being wrongly sent, missed, and multi-sent, and improve the problem of continuous and chaotic uploading of historical data of the data collector caused by network interruption, so that the data of the power station is more perfect, and the failure is realized. traceable.

Description

technical field [0001] The invention belongs to the technical field of electric power data collection, and in particular relates to a data processing mechanism for a data collector of a photovoltaic power station in an off-grid state. Background technique [0002] The data collector is a special hardware device used for national power station information monitoring and monitoring. After the data collector is connected, it can conduct panoramic monitoring of photovoltaic projects in the region from the dimensions of power station installation, power generation, operation and maintenance, etc., remotely and real-time control the health distribution status of the power station, power generation efficiency, etc., and realize real-time tracking and management of the power station. [0003] When the collector is running normally, the network interruption causes the data loss of the power station: 1. The cloud platform server of the photovoltaic monitoring center is unstable, resul...
