Internet+-based photovoltaic agricultural greenhouse control system

Abstract

The invention relates to an internet+-based photovoltaic agricultural greenhouse control system comprising a photovoltaic generating subsystem, an agricultural automatic subsystem, and a remote intelligent control subsystem. The photovoltaic generating subsystem carries out energy conversion and conveys the electric energy that is obtained by photovoltaic generating to the agricultural automatic subsystem, charges a storage battery, and sells the excess electric energy to a power grid company. The remote intelligent control subsystem is capable of monitoring information of the photovoltaic generating subsystem and information in a photovoltaic agricultural greenhouse in real time and makes an optimal solution scheme based on the corresponding information. The remote intelligent control subsystem and the agricultural automatic subsystem carry out regulation and control on environmental parameter information inside an agricultural greenhouse by a network access device. According to the invention, on the basis of cross-border fusion of the digital information technology, the internet technology, and the photovoltaic technology, the system has great theoretical research and social practical values.

Description

technical field [0001] The invention belongs to a control system, in particular to a photovoltaic agricultural greenhouse control system based on "Internet +". Background technique [0002] Energy issues are currently ranked first among the world's top 10 core issues. The massive exploitation and consumption of fossil energy such as coal, oil, and natural gas has brought great damage to the earth's environment. Clean energy such as solar energy will be used as the main energy source in the future for human use. Solar photovoltaic power generation technology has been clearly listed as the focus of my country's "13th Five-Year Plan" scientific and technological development. At present, in terms of industrial scale alone, my country's two major industries, solar thermal utilization and photovoltaic power generation technology, have ranked first in the world. Encouraged by relevant national favorable policies, my country's distributed solar photovoltaic power generation has sh...
