Outdoor photovoltaic data acquisition device

Abstract

The invention discloses an outdoor photovoltaic data acquisition device, and belongs to the technical field of photovoltaic data acquisition. A photovoltaic assembly is in electrical output connectionwith a photovoltaic power generation equipment data acquisition unit for performing data acquisition on photovoltaic power generation equipment, a solar radiation acquisition module for performing data acquisition on solar radiation intensity, and an inverter data acquisition unit for performing data acquisition on an inverter. A data transmission communication unit is in electrical output connection with a central processing unit for processing acquired data and a data calibration module for calibrating the acquired data; the central processing unit is in electrical output connection with analarm, a power module and a distribution module for performing category distribution on the acquired data. The number of data acquisition ways is large, parameter data acquisition is comprehensive, automatic classified induction and arrangement can be achieved, and when parameter data acquisition is abnormal, an alarm can be automatically given out, and a power switch can be automatically cut off.

Description

technical field [0001] The invention relates to the technical field of photovoltaic data acquisition, in particular to an outdoor photovoltaic data acquisition device. Background technique [0002] Solar energy is a renewable and clean energy source. With the emphasis on clean energy at home and abroad and favorable factors such as energy structure adjustment, it is becoming more and more popular. At the same time, it is necessary to collect data from photovoltaic modules for effective monitoring. Usually, photovoltaic data The collector is a solution to meet these needs. However, the photovoltaic data collector products currently on the domestic market collect data from a single source, mainly collecting inverter data, and do not involve the data collection and processing of photovoltaic modules and their equipment. The monitoring also does not provide a quick shutdown function when the collected data is not within the safe range. The collected data needs to be classified a...

[0002] Solar energy is a renewable and clean energy source. With the emphasis on clean energy at home and abroad and favorable factors such as energy structure adjustment, it is becoming more and more popular. At the same time, it is necessary to collect data from photovoltaic modules for effective monitoring. Usually, photovoltaic data The collector is a solution to meet these needs. However, the photovoltaic data collector products currently on the domestic market collect data from a single source, mainly collecting inverter data, and do not involve the data collection and processing of photovoltaic modules and their equipment. The monitoring also does not provide a quick shutdown function when the collected data is not within the safe range. The collected data needs to be classified and stored, which is convenient for the collection of data and has strong centralization. Therefore, we propose a method for outdoor photovoltaic data acquisition device
