The establishment of agricultural automation 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 improving crop yield, the rationality of irrigation cannot be further improved due to the excessive variability of manual operation. The automatic control irrigation is to control all kinds of control valves in the field by collecting and analyzing various factors such as soil, crops, and weather, and then sending relevant information commands from the operating system to reduce the irrational factors of manual analysis and decision-making. Impact on agricultural irrigation. And it is more convenient and efficient than manual operation.
Agricultural automation irrigation system consists of wireless intelligent gateway, drip irrigation intelligent controller, wireless collector, solar panel, various sensors (soil moisture sensor, temperature, humidity, wind speed, wind direction, rainfall, light, leaf humidity, tree diameter sensor, Soil conductivity sensor), control solenoid valve, video camera, high-definition hard disk video recorder, etc., as well as cloud server software, mobile APP software.
The function of agricultural automation irrigation system:
1. Data acquisition 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 turn-stop function: The control system automatically starts sprinkler irrigation according to the dry and wet conditions 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 will stop rotating immediately, the irrigation process will be stopped, and the fault indicator will flash and alarm, and it will automatically resume operation after the overload is eliminated.
5. Automatic stop in rainy days: The switch value of the humidity sensor is used as the input signal of a programmable controller to realize the function of controlling related programs.
6. Power-saving function: The timing controller is normally timed when the power is off, so it is used as the power control of the programmable controller.
7. Emergency stop function: When an emergency occurs, press the emergency stop button, the motor will stop running immediately, the valve will be closed, and the sprinkler will stop irrigating.
8. Fault automatic 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 immediately stops running, the solenoid valve is closed, and the fault alarm light Flashes with a warning sound.
Agricultural automation irrigation advantages:
1. Realize remote transparent wireless transmission of data, realize remote monitoring of farmland irrigation, and reduce labor intensity;
2. In the case of unattended operation, automatic remote command can be carried out according to the needs of crop growth, and the needs of the whole growth period can be designed, and the water can be directly provided to the crops in proportion. Using 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, anywhere.
The importance of agricultural automation irrigation system:
The application of agricultural automation irrigation system has changed the randomness and blindness of human manipulation and operation to a certain extent. It can not only improve the utilization rate of resources, alleviate the contradiction of increasingly tight water resources, but also increase the yield of crops and reduce the cost of agricultural products.
