Abstract

The invention discloses a signal amplification type automatic irrigation control system based on a voltage compensation circuit. The signal amplification type automatic irrigation control system is characterized by mainly consisting of a control chip U3, a diode D2, a detecting probe Q1, a detecting probe Q2, a resistor R2, a resistor R1 and the like, wherein the resistor R2 is connected in series between the detecting probe Q1 and a P pole of the diode D2; the resistor R1 is connected in series between the detecting probe Q1 and a VIN tube pin of the control chip U3. The signal amplification type automatic irrigation control system has the advantages that a current signal output from the control chip can be subjected to amplification processing, so that the control chip well recognizes the signal and outputs an accurate control signal, and the control precision of the control system on a water pump is greatly improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a signal amplification 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...
