Data acquisition method based on photovoltaic collector

Abstract

The invention discloses a data acquisition method based on a photovoltaic collector, which relates to the technical field of photovoltaic collectors, and comprises the following steps: a photovoltaic input end is connected with a port of an input equipment end in the photovoltaic collector and transmits information data to a memory, and the memory is in communication connection with a port of an output equipment end; and the information data in the memory is transmitted to the photovoltaic inverter through the encryption circuit to realize the collection of photovoltaic data. According to the scheme, electrical signals generated by externally serially connected photovoltaic panels enter the input equipment end through the photovoltaic input end to be transmitted, data are stored by the storage in the data transmission process, programs can only be executed in sequence, flexibility is lacked, and some short tasks can only be processed in real time by using an interrupt function; the method solves the problem that data redundancy is caused in the processing process due to the fact that the method is extremely inconvenient to use in complex data processing, is simple and practical, and integrates and distributes a traditional framework information structure.

Description

technical field [0001] The invention relates to the technical field of photovoltaic collectors, in particular to a data collection method based on photovoltaic collectors. Background technique [0002] Energy is an important material basis for human survival and an important impetus for social and economic development. However, with the advancement of industrialization and the rapid increase of world population, the shortage of conventional energy and environmental pollution have become increasingly apparent, which have been unable to meet the needs of human society. Sustainable development and the need to improve the quality of life, for this reason, from the long-term goal of human development, the development of green renewable energy is an inevitable trend. [0003] With the development of science and technology, the solar energy industry is developing more and more rapidly, and its application scope is becoming wider and wider. Therefore, the equipment status and data c...

[0004] After retrieval, Chinese patent CN111667676A discloses a data collection method based on a photovoltaic collector. The patent discloses that the photovoltaic collector includes an MCU for data processing. The MCU is an important processing module of the collector and is responsible for processing various implementation logics of the software, such as The implementation logic of the data collection and uploading of the photovoltaic inverter shows that the MCU is an important part of the solution. However, there are some problems in the use process. Only a single-task mechanism can be used, and the program can only be executed sequentially. Flexibility, can only use the interrupt function to process some shorter tasks in real time, it is extremely inconvenient to use in more complex data processing, resulting in data redundancy in the process of processing, in addition, in the process of outdoor use, affected by the wind speed of the environment Due to the influence of wind speed, the collector shakes. Due to the redundancy of data, the processing speed slows down, resulting in excessive load performance between points, and the loosening of the wired connection of each point affected by the wind speed, resulting in the operation of photovoltaics. The instability of the harvester is aggravated to generate vibration potential energy
