Abstract

The invention discloses a signal amplification type automatic irrigation control system based on a protective circuit. The signal amplification type automatic irrigation control system is characterized in that the system is mainly composed of a control chip U3, a diode D2, a detection probe Q1, a detection probe Q2, a resistor R2,the protective circuit, a resistor R1 and the like, wherein the resistor R2 is connected between the detection probe Q1 and a P pole of the diode D2 in series, the protective circuit is connected with a VIN pin of the control chip U3, and the resistor R1 is connected between the detection probe Q1 and the protective circuit in series. By the adoption of the signal amplification type automatic irrigation control system, a current signal output to the control chip can be amplified and thus can be well recognized by the control chip, and a precise control signal is output, so that the accuracy of control over a water pump can be improved greatly.

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 protection 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 defec...
