Single-chip microcomputer based intelligent irrigation device and operation mode thereof

Abstract

The invention discloses a single-chip microcomputer based intelligent irrigation device and an operation mode thereof and belongs to the technical field of intelligent irrigation. The operation mode includes that the given value of humidity suitable for planting plants is input to a single-chip microcomputer, a humidity sensor measures the soil layer and inputs the humidity measurement value to the single-chip microcomputer, the measurement value and the given value are compared through the single-chip microcomputer, and if a deviation appears, a deviation signal is processed through the single-chip microcomputer which outputs a control signal to a contactor; if the measurement value is greater than the given value, that is, the humidity is too high and continuous irrigation is not needed,the signal-chip microcomputer outputs a single to disconnect the contactor, and a controlled mechanism, namely a circuit of a centrifugal pump, is cut off to stop the centrifugal pump and water supply irrigation; if the measurement value is less than the given value, that is, the soil humidity is low and irrigation spraying is needed, the single-chip microcomputer outputs a single to close the contactor, the circuit of the centrifugal pump is connected, the centrifugal pump can start to run to spray water from rocker arm sprinkles on a drain pipe for irrigation, and intelligent irrigation isrealized through the single-chip microcomputer.

Description

technical field

[0001] The invention belongs to the technical field of intelligent irrigation, and in particular relates to an intelligent irrigation device based on a single-chip microcomputer and its operating mode. Background technique

[0002] my country is one of the 13 most water-deficient countries in the world. The per capita is only 2100 cubic meters, which is only 28% of the world's average level. In terms of stages and levels, throttling is the primary way. Agriculture accounts for about 62% of the country's total water consumption, and some areas as high as 90%. Agriculture is my country's largest water user. Therefore, vigorously developing agricultural intelligent and efficient water-saving irrigation has naturally become an inevitable choice for my country to alleviate the contradiction between water supply and demand.

[0003] Single-chip microcomputer, also known as single-chip microcontroller, is not a chip that completes a certain logic function, but integ...
