Abstract

The invention discloses a protective automatic irrigation control system based on a voltage compensation circuit, which is characterized in that: a control chip U3, a diode D2, a detection probe Q1, a detection probe Q2, and a P The resistor R2 between the electrodes is composed of. The present invention adopts the A6210 integrated chip as the control chip, and combines the logic gate to control the water pump. Compared with the traditional control system using mechanical switches to control, the present invention has a lower error rate and can control the work of the water pump more accurately. The invention can compensate the voltage drop caused by wires or resistance, so that the working voltage of the invention is more stable.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a protection type automatic irrigation control system based on a voltage compensation circuit. Background technique [0002] The application of modern agricultural technology has brought huge economic, social and ecological benefits to the society. With the development of society, people's awareness of water saving has gradually increased. In order to achieve the purpose of water saving, people usually use automatic irrigation control systems to control water pumps to irrigate crops to improve irrigation water efficiency. However, there are still some problems in agricultural irrigation at present, that is, the control precision of the automatic irrigation control system adopted is low, and the work of the water pump cannot be accurately controlled, which cannot meet people's requirements. Contents of the invention [0003] The purpose of the present invention is to solve the ...
