Monitoring data collecting terminal of photovoltaic power station and monitoring data system

Abstract

The invention discloses a monitoring data collecting terminal of a photovoltaic power station and a monitoring data system. The monitoring data collecting terminal comprises a data collecting module, a storage module, a data processing module, a remote communication module and a power module. The data collecting module is used for collecting working parameters of the photovoltaic power station every preset time, and the data processing module is used for conducting classified and graded storage on the data collected by the data collecting module, conducting filtering on the normal data and sending a message notice if abnormal data exist. The remote communication module sends the message notice to a remote control device. Thus, the requirement for monitoring the data of the power station remotely of a user is guaranteed, and the effect that the photovoltaic power station runs safely and stably on the unattended condition is realized; operation data of the photovoltaic power station and weather information of the photovoltaic power station are sent to the remote control device so that a user can comprehensively know and timely grasp the operation situations of all links of the photovoltaic power station, and safe operation of the photovoltaic power station can be guaranteed.

Description

technical field [0001] The invention relates to a monitoring technology of a photovoltaic power station, in particular to a monitoring data collection terminal and a monitoring data system of a photovoltaic power station. Background technique [0002] The data collection and monitoring of traditional photovoltaic power plants are mainly provided by inverter manufacturers with related equipment to monitor some parameters of photovoltaic power plant operation, but these methods are difficult, or even cannot directly control the operating status of the inverter, and cannot obtain photovoltaic The information of other equipment in the power station and the control of these equipment are likely to form "isolated island" systems, which cannot form a unified data collection and monitoring. [0003] With the development of photovoltaic power generation, more and more independent and grid-connected photovoltaic power plants are put into operation. Most of these power stations are bu...
