Agricultural multifunctional variable controller

Abstract

The invention discloses an agricultural multifunctional variable controller. The controller comprises a central processing unit, and a serial data interface circuit, an analog quantity signal interface circuit, a digital quantity signal interface circuit, a liquid crystal screen interface circuit, a touch screen interface circuit, an alarm circuit, an audio interface circuit, a watchdog circuit and a variable execution mechanism driving circuit which are connected with the central processing unit, wherein the liquid crystal screen interface circuit is connected with the liquid crystal display screen; the touch screen interface circuit is connected with a touch screen; both the alarm circuit and the audio interface circuit are connected with a speaker; and the watchdog circuit is connected with a data memory. The controller has three operation types, namely variable fertilization, variable spray and variable irrigation, and three operating modes, namely GPS positioning automatic control, dead reckoning automatic control and manual input control. The controller has the advantages of low cost and suitability for various farming link operations.

Description

technical field [0001] The invention belongs to the field of agricultural intelligent equipment, and relates to a variable controller, specifically an agricultural multifunctional variable controller that can realize variable fertilization, variable spraying and variable irrigation operations with corresponding work tools, sensors and variable actuators. controller. Background technique [0002] Fertilization, spraying and irrigation are indispensable farming links in the process of crop growth, which directly affect the yield and quality of agricultural products. Improper farming practices will not only increase the production cost of agricultural products, but also destroy the ecological balance of the surrounding environment. With the advancement of science and technology and the improvement of human living standards, how to reasonably use the soil characteristics of the cultivated land and the production resources around the land to increase or maintain the output of ag...
