Abstract

The invention discloses a variable spray control system based on an AT89C52 single-chip microcomputer and belongs to the technical field of variable spray control. The variable spray control system ismainly formed by a pesticide box, a pump, a flow sensor, a pressure sensor, an electric control valve, a sprayer, a speed transmitter, a processor, a key module and an LED, and is characterized in that the pesticide box is connected with the pump, the flow meter is connected with the pump, the pressure sensor is connected with the flow meter, the electric control valve is arranged downstream of the flow sensor and upstream of the spray, the speed transmitter and the key module are connected with the LCD and the processor, and the processor controls the flow sensor, the pressure sensor and theelectric control valve. The variable spray control system has the advantages of good instantaneity and high reliability, the traditional application method can be changed greatly, and the applicationaccuracy is improved.

Description

technical field [0001] The invention relates to a variable spray control system based on an AT89C52 single-chip microcomputer, and belongs to the technical field of variable spray control. Background technique [0002] The large-scale input of agricultural chemicals has caused damage to the environment. The significance of precision agriculture lies in improving the application rate, saving resources, maintaining ecological balance and protecting the environment, and promoting the sustainable development of agriculture. However, my country's pesticide application technology is in the backward state of the world, and can no longer meet the requirements of the development of precision agriculture in the 21st century. In order to improve the level of pesticide application in our country and meet the requirements of precise pesticide application. The invention develops a variable spray control system based on the AT89C52 single-chip microcomputer. Contents of the invention ...
