Irrigation requirement computation system and method under climatic variation background

Abstract

The invention discloses an irrigation requirement computation system and an irrigation requirement computation method under a climatic variation background. A historical data input module inputs collected climate parameters and crop information into a data forecasting module; the data forecasting module forecasts future climate parameters and crop information according to historical climate parameters and crop information; a sensor state control module selects a wireless sensor needing to be awakened and wireless sensor awakening time according to the forecasted future climate parameters and crop information, and collects the corresponding climate parameters and crop information in real time while the wireless sensor is awakened; and an irrigation strategy generation and execution module generates an irrigation strategy, and irrigates crops in time. The irrigation requirement computation system provided by the invention, irrigation water of the crops can be effectively managed while the wireless sensor has minimal network energy consumption; the computation method not only depends on the climate parameters and crop parameters, but also comprehensively considers economic efficiency of the crops and economy bearing capacity of farmers, so that utilization efficiency of water resources can be improved, and climatic variations can be effectively tackled; and meanwhile, consumption of network resources is greatly reduced by a dormant state of the wireless sensor, and a device life is improved.

Description

technical field [0001] The invention relates to the field of water resource development and utilization, in particular to an irrigation water demand calculation system and a method thereof. Background technique [0002] Climate change and its impact are one of the major environmental issues facing the world today, and have attracted widespread attention from all walks of life. Over the past 100 years, the global surface temperature has increased by 0.56-0.92°C. The Intergovernmental Panel on Climate Change (IPCC) pointed out that global warming will cause billions of people on the earth to face water and food shortages, and the frequency of natural disasters such as floods, droughts, and typhoons will increase. At the same time, due to the double impact of human activities, some new features have emerged in the natural water cycle. [0003] Farmland irrigation is the basic guarantee for food production. At present, agricultural irrigation water has accounted for 70% of my...
