Single-chip microcomputer control based automatic irrigation system

Abstract

The invention discloses a single-chip microcomputer control based automatic irrigation system. The system comprises a soil temperature and humidity detection unit, a water source detection unit, an early warning unit, an ARM single-chip microcomputer and a wireless communication module. The soil temperature and humidity detection unit is used for detecting soil temperature and humidity in real time, and the water source detection unit is used for detecting irrigation water pH value, chlorine content and irrigation water level value in real time. By the ARM single-chip microcomputer for controlling the automatic irrigation system, water resource utilization effects are effectively improved; when soil humidity does not meet set requirements, an electromagnetic valve is automatically startedto realize spray irrigation, and effective irrigation can be realized by adjustment of water pump flow rate, pressure and water spraying direction. By a solar storage battery for power supply, power saving, simple structure, reasonable design, convenience and quickness in operation and high intelligent level are realized, energy saving is realized while temperature and humidity integrated regulation is realized as well, and great utilization effects and convenience in popularization and utilization are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an automatic irrigation system controlled by a single-chip microcomputer. Background technique [0002] With the development of the times and the advancement of science and technology, agriculture, as the most important part of basic necessities of life, is gradually developing towards intelligence, electrification, and automation. Vigorously developing agriculture has become the top priority in the competition of national power in the 21st century. However, with the rapid increase of industrial and urban water consumption, the proportion of rice agricultural water consumption in the country's total water consumption has dropped from about 80% in the 1970s to about 70% at present, and there is still a downward trend, and the contradiction between supply and demand of agricultural water is increasing. However, on the one hand, rice agriculture is short of water, and...

However, with the rapid increase of industrial and urban water consumption, the proportion of rice agricultural water consumption in the country's total water consumption has dropped from about 80% in the 1970s to about 70% at present, and there is still a downward trend, and the contradiction between supply and demand of agricultural water is increasing. However, on the one hand, rice agriculture is short of water, and on the other hand, the phenomenon of water waste in rice agriculture is widespread. The current effective utilization rate of water in rice agriculture in my country is only 30%-40%, which means that more than half of the water is used for transportation and irrigation. Wasted in the process and cannot be utilized by rice crops
