Cloud based irrigation district water-saving irrigation decision-making support system

Abstract

The invention discloses a cloud based irrigation district water-saving irrigation decision-making support system. The system comprises a cloud server, wireless data transmission modules, single chip microcomputers, sensors and a gate, and the cloud server comprises a database and a webpage. Decision-making steps of the system include: setting up the database, carrying out multi-point measurement of paddy field moisture and water level of a district to be measured, and storing average data in the database; automatically capturing data of an official weather forecast website, storing the data in the database, and using temperature data for estimating water requirement of crops; according to measured data and a corresponding water balance model, computing to judge whether irrigation is needed or not, and if so, determining irrigation amount and irrigation time; and enabling the webpage to be capable of serving as a data display terminal and a lower computer control terminal. The irrigation district water-saving irrigation decision support system is set up on the basis of the cloud server, data is transmitted through a mobile network, and accordingly data transmission range can be enlarged, and irrigation district informatization management level is improved.

Description

technical field [0001] The invention relates to the field of farmland water conservancy engineering, in particular to a cloud-based water-saving irrigation decision support system for irrigation areas. Background technique [0002] With the development of the economy, the competition of industrial water, urban water, environmental water and agricultural water is becoming increasingly severe, resulting in the shortage of agricultural water. On average, agriculture in developing countries accounts for 70 percent of total water use. Agricultural water use in developed countries accounts for an average of 50 percent of total water use. The amount of water resources in my country is relatively small, and the distribution of time and space and the combination of water and soil resources are not balanced, so that the contradiction of water shortage is prominent, which is the main factor restricting the development of my country's agriculture. [0003] In addition, most of the irr...
