Agricultural irrigation device based on chaotic signal control

Abstract

The invention relates to an agricultural irrigation device based on chaotic signal control. The agricultural irrigation device comprises a power supply module, a control module, a driving module, a monitoring module and a plurality of nozzles, wherein the power supply module is connected with the control module, the driving module and the monitoring module through a circuit; the control module is in communication connection with the driving module, the monitoring module and the nozzle; the control module comprises a single-chip microcomputer, the single-chip microcomputer is used for bearing a control program, and the control program adopts a chaos model and can generate PWM waves with chaos characteristics; the driving module comprises a driving device and a variable-frequency water pump, the driving device receives the PWM wave signals generated by the single-chip microcomputer, converts the PWM wave signals into voltage and current signals and outputs the voltage and current signals to the variable-frequency water pump, and therefore, different working pressures are provided for the variable-frequency water pump; and the monitoring module monitors the temperature and the humidity in an irrigation range which can be covered by the nozzle in real time, and feeds back the temperature and the humidity to the control module, and the single-chip microcomputer processes and analyzes feedback signals so as to control automatic opening and closing of the nozzle.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, that is, electronic control equipment, and in particular relates to an agricultural irrigation device controlled based on chaotic signals. Background technique [0002] my country is a large agricultural country, and the water used for agricultural irrigation reaches hundreds of millions of cubic meters every year. However, due to the limitation of field irrigation technology, the amount of water that can be absorbed by crops is not much, resulting in a waste of water resources. In recent years, those skilled in the art have developed water-saving irrigation methods such as drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, and under-film irrigation. The sprinkler irrigation technology uses water pumps and pipeline systems or utilizes the drop of natural water sources to spray water with a certain pressure. In the air, it is an irrigation method that disperses into...

[0002] my country is a large agricultural country, and the water used for agricultural irrigation reaches hundreds of millions of cubic meters every year. However, due to the limitation of field irrigation technology, the amount of water that can be absorbed by crops is not much, resulting in a waste of water resources.

In recent years, those skilled in the art have developed water-saving irrigation methods such as drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, and under-film irrigation. The sprinkler irrigation technology uses water pumps and pipeline systems or utilizes the drop of natural water sources to spray water with a certain pressure. In the air, it is an irrigation method that disperses into small water droplets or forms a mist that falls on the plants and the ground. However, most sprinkler irrigation systems spray with a specified lift and angle. Although this improves the utilization rate of water resources, there are still artificial settings. The problem of spraying range and uneven spraying, it is impossible to flexibly adjust the spraying range according to the real-time needs of crops
