Intelligent irrigation systems and agricultural sensors
Background:
Many countries in the world are facing the problem of water shortage. Drinking water and irrigation water are very important to us. Irrigating both fields and gardens requires a lot of water. This process inevitably leads to waste of water resources. Therefore, intelligent irrigation systems are becoming more and more important. It consists of advanced sensors and controls to minimize wasted water.
Smart irrigation technology has been proven to reduce water waste by 20-40% compared to traditional irrigation technology. It can scientifically determine whether to water plants and how much to water them based on current regional weather data and soil moisture conditions. Flexible adjustment of irrigation time and irrigation position. Reduce water waste and improve irrigation efficiency while maintaining plant health and quality.
Intelligent irrigation system composition
Because the intelligent irrigation system has powerful functions and can realize automatic water-saving irrigation, its composition is relatively complex. Generally, it is composed of monitoring part, control part, transmission part and terminal platform. The different parts work together to form a unit. The following is the component of each part:
Monitor the part
Various sensors are the monitoring units of intelligent irrigation. The main sensors are soil moisture sensor, wind speed sensor, evaporation sensor, leaf moisture sensor, rain and snow sensor and data collector.
The control part
Various control valves are the basis of automatic irrigation. Valves that support remote switching include butterfly valve, pulse valve, ball valve, etc. Different valves and water pipes can be selected according to different irrigation areas.
The transmission part
The monitored data signal and command signal are transmitted at the terminal and the control terminal respectively. If LORA wireless transport is used, then the transport part is the LORA gateway and the data concentrator. If you’re using home wifi, the transmission part is the router and the monitor host.
The terminal platform
The terminal platform is generally a software system for data collation and analysis. It can analyze data, store data, and issue control commands. The platform software supports mobile phones and computers.
Various sensors transmit soil moisture and meteorological data wirelessly to the platform, which analyzes and studies the data. It analyzes the amount of water and area to irrigate and sends wireless commands to control valves at each point. The controller controls the opening or closing of the water valve. Provide proper irrigation. As outdoor temperatures rise or rainfall changes, smart irrigation systems take into account site-specific variables, such as soil type and sprinkler rate. Adjust watering time constantly.
Irrigation and fertilization machine-irrigation equipment
Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. The integration of water and fertilizer is to use the pressure system (or the natural drop of the terrain) to mix the soluble solid or liquid fertilizer according to the soil nutrient content and the fertilizer requirement law and characteristics of the crop type, and the fertilizer solution and the irrigation water are mixed together through the controllable pipeline System water supply and fertilizer supply. After the water and fertilizer are melted, spray irrigation is formed through pipes, spray guns or nozzles, which are evenly, regularly, and quantitatively sprayed on the growth area of crops, so that the soil in the main growth area always maintains looseness and suitable moisture content. According to the characteristics of fertilizer requirements of different crops, soil environment and nutrient content conditions, and the law of fertilizer requirements, the requirements of different growth periods are designed, and water and nutrients are fixed and quantified, and directly provided to crops in proportion. Water and fertilizer integrated machine (fertilizer equipment) is the product of water and fertilizer integration technology.
Advantages of intelligent irrigation system
1.It saves manpower. Compared with traditional irrigation, intelligent irrigation is an automatic method. Irrigators do not need to walk around irrigating fields with nozzles. There is also no need to open or close the water valve manually. A mobile phone or a computer can do the whole irrigation job. No more worrying about garden plants wilting from lack of water while traveling. You can safely play anywhere.
2.Save water. The purpose of smart irrigation is to save water, and it replaces the previous flood irrigation. It uses less water to meet the growth needs of plants. Intelligent irrigation systems can collect soil moisture data and effectively control irrigation water use. It is also equipped with a recycling system to save water.
3.Remote management. You do not have to be present in the irrigated area to perform monitoring data analysis and irrigation work using a mobile phone or computer. Just turn on your phone at the right time and observe how the plant is growing. One person can manage multiple cloud platforms at the same time and irrigate thousands of acres of farmland, greatly saving labor costs.
4.Fine irrigation. Adjust the irrigation mode in time according to the real-time data measured by the sensor. Water the plants regularly and quantitatively according to their growth. Irrigate the whole garden evenly so that each flower grows healthily.
5.Intelligent control. Timing irrigation, remote irrigation, circulation irrigation, three irrigation methods flexible switch, the head modification immediately effective.For more information about irrigation equipment, please consult JXCT.
