Large-scale water-saving irrigation network with solar photovoltaic driving and GPRS wireless communication monitoring

Abstract

The invention relates to a large-scale water-saving irrigation network with solar photovoltaic driving and GPRS wireless communication monitoring, which comprises a pre-stage water taking system and a basic irrigation unit. The pre-stage water taking system utilizes the electricity generated by a solar cell to pump water from a water source through a main water pump controlled by a wireless online pre-stage measuring and controlling module, and the water is distributed to local water reservoirs through pipelines by a main dividing valve; and the basic irrigation unit also utilizes the electricity generated by the solar cell, drives unit water pumps to pump water from the local water reservoirs through wireless online unit measuring and controlling modules and carries out drip irrigation or sprinkler irrigation through a dividing valve and local pipelines. A computer administration center carries out real-time monitoring on soil moisture, water levels in the water reservoirs and irrigation amount of an irrigation unit block through a wireless network to realize all-weather and full-automatic intelligent management of the irrigation network. The invention effectively improves the feasibility of large-scale water-saving irrigation in water-deficient regions without electricity, saves water by over 80 percent compared with the traditional irrigation mode, and saves farmland occupied by the traditional irrigation channel by about 3-5 percent.

Description

technical field [0001] The invention relates to the application of solar photovoltaic cells and an electric water lifting device, in particular to a water-saving irrigation network for intelligent measurement and control by means of GPRS wireless communication. Background technique [0002] Most of the existing agricultural irrigation methods use electricity or diesel power to pump water from the water source, and perform full-cover infiltration irrigation on the soil where agricultural and forestry crops grow through the irrigation canal network. This traditional irrigation method makes most of the water directly evaporate or infiltrate into the ground through the soil surface, and only a small part is absorbed by agricultural and forestry crops, resulting in a huge waste of water resources. For water-scarce areas, hilly and sandy soils, this traditional irrigation method cannot be implemented at all due to the constraints of available resources and economics. In addition,...
