Background
China is a big agricultural country from ancient times, the past irrigation modes are single, and the irrigation modes are basically developed by artificial irrigation until modern agricultural facilities. But the effect is not obvious, and only so many convenient crop irrigation modes can be provided for people. For example, irrigation, drip irrigation, flood irrigation, drip irrigation, etc., but the water utilization rate is not high, such as a dropper, the water utilization rate is only 40%. The low water utilization rate is the biggest problem of all irrigation methods, and although some technologies are applied, the utilization rate of water resources is improved, but the problems are not solved fundamentally. Such as how large water is used, how much water is used, how long water is used, etc. in the underground drip irrigation process, these problems are artificially difficult to control.

The concept of developing an automatic irrigation system for farmlands is an important water saving, and the core of the system is to control and effectively utilize water resources. In order to improve irrigation efficiency, reduce labor cost and save water resources, the development of automatic irrigation technology has become a necessary trend. The development of the concept of the farmland automatic irrigation system is an important means for controlling and effectively utilizing water resources, the farmland irrigation accuracy and effectiveness can be improved, scientific and effective management of the irrigation operation process is facilitated, farmers can judge whether the farmland irrigation is suitable or not according to self experience for many years, the labor amount can be reduced well, more importantly, the farmland irrigation system can accurately, regularly and quantitatively supply water to crops in time, the yield and the quality of the crops can be improved, water and energy can be saved, and the labor cost can be reduced.
Although China has a set of self automatic irrigation system, the system is still in a primary development stage, all aspects of the system are not perfect, most of the irrigation systems are still in a manual operation stage, and even if some automatic irrigation control systems are adopted in individual places, the automatic irrigation control systems are imported from foreign countries or small-scale local control systems. The autonomous irrigation control system independently developed in China is far from mature and lacks key technology. The Taixing city of Jiangsu province finds that the local conditions are very suitable for a remote automatic control system of water-saving irrigation, and the remote automatic control system is applied for the first time, so that the effect is very good. The Chinese irrigation automatic control system has a large gap relative to developed countries, and the technology is lagged behind and not widely applied.

when the soil humidity is high, the resistance value between two electrodes of the humidity sensor is low, the V1 is in a conducting state, the V2 and the V3 are in a stopping state, the emitter of the V3 does not output 12V Voltage (VDD), the multivibrator does not work, the thyristor VT is not conducted, and the electromagnetic valve or the water pumping motor does not work; when the soil is relatively dry, the resistance between the two electrodes of the humidity sensor is increased, so that V1 is cut off, V2 and V3 are conducted, the IC is electrified to work, the multivibrator starts to work in an oscillating mode, a high level is output from a pin 3 of the IC, V4 and VT are conducted, VL is lightened, and the electromagnetic valve or the motor is electrified to work.
After the IC is powered on, the output voltage of the emitter of the V3 charges a capacitor C2 through resistors R5-R7, so that the voltages of the pins 6 and 2 of the IC are gradually increased. When the voltage at the two ends of the C2 rises to 2/3VDD, a trigger in the IC overturns, the 3 feet of the trigger change from high level to low level, so that V4 and VT are cut off, the electromagnetic valve or the motor is powered off, and spraying or sprinkling irrigation is stopped. At the moment, a discharge circuit in the IC works, C2 discharges through a pin 7 of the IC, when the voltages of a pin 2 and a pin 6 of the IC are reduced to 1/3VDD, a trigger in the IC is inverted again, a pin 3 outputs high level again, V4 and VT are conducted, and the electromagnetic valve or the motor is electrified to work again. The intermittent operation is carried out in such a way, until the soil humidity reaches the requirement, V1 is conducted, V2 and V3 are cut off, and the multivibrator and the control execution circuit stop working.
Adjusting the resistance of resistor R7 or changing the capacitance of capacitor C2 changes the operating frequency of the multivibrator, thereby adjusting the spray and power down pause times.
S2 is a manual switch, after S2 is switched on, the electromagnetic valve or the motor is electrified to work without being controlled by the automatic sprinkling control circuit.
