The automatic irrigation system is a system used in agriculture, horticulture and landscape. It can automatically adjust the amount and time of irrigation water according to the water needs of plants and environmental conditions, increase crop yields, improve the ecological environment, and save water resources. The working principle and technical parameters of the automatic irrigation system will be analyzed below.
Working principle
1. Sensor detection: Automatic irrigation systems are usually equipped with multiple sensors, such as soil moisture sensors, light sensors, temperature sensors, etc., to monitor environmental conditions and plant water needs.
2. Data analysis: The data collected by the sensor will be transmitted to the controller. The controller will analyze and process the data to determine the water needs of the plants and decide whether to irrigate.
3. Control execution: The controller controls the execution of valves, pumping stations and other equipment based on the analysis results, and starts or stops the supply of irrigation water to ensure the water needs of plants.
4. Timing control: The automatic irrigation system also has a timing control function, which can set different irrigation times and water volumes according to different plant growth stages, and perform scheduled or interval irrigation.
Analysis of technical parameters
1. Soil moisture sensor: Soil moisture sensor is used to measure the moisture content of soil, usually using resistive or capacitive sensors. Technical parameters include measurement range, error range, response time, etc.
2. Light sensor: The light sensor is used to measure the light intensity and determine the light conditions of the environment where the plant is located. Technical parameters usually include measurement range, linearity, response time, etc.
3. Temperature sensor: The temperature sensor is used to measure the temperature of the environment and determine the temperature conditions of the plant. Technical parameters include measurement range, accuracy, response time, etc.
4. Controller: The controller is the core component of the automatic irrigation system and is responsible for data analysis, judgment, decision-making and control execution. Technical parameters include input and output interface types, processing speed, storage capacity, etc.
5. Valve and pump station: Valve and pump station are the execution components of the automatic irrigation system and are responsible for controlling the supply of irrigation water. Technical parameters include flow rate, working pressure, opening and closing time, etc.
6. Water supply system: The water supply system includes water sources, water pipelines, sprinklers, etc. Technical parameters include water supply capacity, pipe diameter, sprinkler irrigation range, etc.
7. Power supply system: The power supply system includes the power supply and power grid to provide stable power supply for the automatic irrigation system. Technical parameters include voltage, frequency, power, etc.
8. Control strategies and algorithms: Automatic irrigation systems use different control strategies and algorithms to regulate irrigation water volume and time. Common ones include threshold judgment, feedback control, fuzzy control, neural network control, etc.
Summary: The automatic irrigation system detects the water demand of the environment and plants through sensors, and controls valves and pump stations through controller analysis and decision-making to achieve automatic irrigation, increase crop yields, improve the ecological environment, and save water resources. Its technical parameters mainly include the measurement range, error range, response time of the sensor, the processing speed and storage capacity of the controller, the flow rate and working pressure of the valve and pump station, etc.
