Agricultural automatic irrigation system


      The establishment of agricultural automatic irrigation system can improve the water-saving level of agricultural irrigation. Although the original water-saving irrigation system has an obvious effect on reducing crop irrigation and increasing crop yield, the variability of manual operation is too large, so that the rationality of irrigation cannot be further improved. The automatic control of irrigation is to control various control valves in the field through the collection and analysis of various factors such as soil, crops, weather, etc., and then the operating system sends relevant information instructions to control various control valves in the field, so as to reduce the unreasonable factors of manual analysis and decision-making. Impact on agricultural irrigation. And it is more convenient and efficient than manual operation.


      The agricultural automatic irrigation system consists of a wireless smart gateway, a drip irrigation smart controller, a wireless collector, solar panels, various sensors (soil moisture sensor, temperature, humidity, wind speed, wind direction, rainfall, light, leaf humidity, tree diameter sensors, Soil conductivity sensor), control solenoid valve, video camera, high-definition hard disk video recorder, etc., cloud server software, mobile phone APP software.

Functions of agricultural automatic irrigation system:
1. Data collection function: it can receive the analog quantity collected by the soil moisture sensor.
2. With the functions of timing control and cycle control, users can flexibly choose control methods according to their needs.
3. Automatic rotation and stop function: The control system automatically starts sprinkler irrigation according to the dry humidity of the soil, and controls the motor to rotate at the required speed.
4. Motor overload protection function: When the motor is overloaded, the motor immediately stops rotating, the irrigation process is stopped, and the fault indicator flashes to alarm, and it automatically resumes operation after the overload is eliminated.
5. Automatic stop in rainy and cloudy days: Use the switch value of the humidity sensor as the input signal of a programmable controller to realize the function of controlling related programs.
6. Power-saving function: The timing controller will normally time when the power is off, so it is used as the power control of the programmable controller.
7. Emergency stop function: When an emergency accident occurs, press the emergency stop button, the motor will immediately stop running, the valve will be closed, and the sprinkler will stop irrigation.
8. Automatic fault detection function: When the irrigation system fails, such as water pipe rupture (water pressure is zero), sensor failure, motor failure, inverter failure, solenoid valve failure, etc., the water pump will immediately stop running, the solenoid valve will be closed, and the fault warning light will be displayed. Flashing and accompanied by a warning sound.

Advantages of agricultural automatic irrigation:
1. Realize remote transparent wireless transmission of data, realize remote monitoring of farmland irrigation, and reduce labor intensity;
2. In the case of unattended, automatic remote command can be designed according to the growth requirements of the crops during the whole life cycle, and the water will be directly provided to the crops at a fixed time and proportionally. The use of this system can greatly improve the efficiency of irrigation water utilization.
3. Through advanced Internet of Things technology, users can remotely monitor and receive early warnings through computers or mobile phones anytime and anywhere.


The importance of agricultural automatic irrigation system:
The application of agricultural automatic irrigation system has changed the human manipulation, randomness and blindness of operation to a certain extent. It can not only improve resource utilization and alleviate the contradiction of increasingly tense water resources, but also increase the output of crops and reduce the cost of agricultural products.
