Application of Electronic Devices in Intelligent Irrigation System
Speaking of smart irrigation, it is natural to think that it corresponds to the traditional irrigation method. Related research shows that compared with traditional irrigation systems, the cost of smart agricultural irrigation systems is about the same, but the water saving can reach 16% to 30%. A large amount of water resources was wasted due to irrigation in many countries. Take the United States as an example. About ten years ago, the United States wasted 852 billion liters of water resources every year. If the installation of intelligent agricultural irrigation systems can effectively control the water flow and achieve energy saving Water purpose. In addition, in China, agricultural water consumption accounts for about 80% of the total water consumption. Due to the generally low efficiency of agricultural irrigation, the water utilization rate is only 45%, while countries with high water resource utilization rates have reached 70% to 80%. Therefore, solving the problem of agricultural irrigation water is very important to alleviate the shortage of water resources. The intelligent irrigation system came into being under this background.
Intelligent irrigation is called intelligence because it uses a variety of high-tech such as sensor technology, automatic control technology, computer technology, and wireless communication technology. It is worth mentioning that the detection of power consumption is also an important part. The electronic components that need to be used may include power monitoring smart sensors and current transformers. Of course, the power consumption detection of the entire system needs to be measured by smart meters.
When it comes to automatic control systems, various automatic switches will inevitably be used to complete the execution of the control results. The switches here include relays, circuit breakers, and solenoid valves. In detail, relays are divided into latching relays and power relays. Magnetic latching relays or motor latching relays are more suitable for switching on and off the branch of the circuit; high-power relays are suitable for the branch of the motor for water delivery. Turn on or off; the circuit breaker is suitable for switching control on the main circuit of the circuit; the solenoid valve is used to control whether the sprinkler is sprayed or not. Since the scale of smart irrigation is generally not small, and the safety is not negligible when manual operation is required, it is generally recommended to install a leakage current detection and alarm system, and the indispensable component of the entire electricity safety system is the leakage current sensor. It can set the adjustment function for the AC and DC leakage current alarm value, and with the computer digital information processing technology, it is easy to achieve leakage protection.
So far, this issue of the popularization of the application of electronic devices in the intelligent agricultural irrigation system has come to an end. In short, the irrigation system has a profound impact on the use of water resources. It not only relieves the tension of water resources to a certain extent, but also increases crops. Production, and reduce the cost of agricultural products.Follow us to learn more about electricity.
