3. How Dose smart irrigation system 工作
The types of smart irrigation system
Bus-controlled irrigation
A bus-controlled irrigation system means that the entire irrigation system is controlled by a bus control as a measurement and control terminal. In the bus-controlled irrigation system, every measurement and control terminal is also relatively independent, and can independently collect, integrate and judge the water demand information of the gardens, as well as the basic irrigation operations. The water demand information of vegetation is firstly gathered by every measurement and control terminal, 然後訊息將傳輸至中央電腦監控系統, 對其進行分析處理，產生園林灌溉參數，用於自動啟動和調整灌溉系統進行灌溉. 更重要的是, 該系統包含一個專家系統. 可以邀請相關專業人士，結合系統儲存的資料和植被的實際生長情況，對園林灌溉進行個人化指導，達到更科學的效果。, 直觀高效以及更直觀的灌溉. 與無線遙控器相比, 總線控制覆蓋範圍更廣，整體投資成本更低. 所以, 應用價值極高.
無線遙控灌溉
The wireless remote control irrigation system stands for a system that supports irrigation using the remote terminal units as an information relay station. Specifically speaking, the remote terminal is in charge of gathering information on vegetation fertilizers and water requirements. Then the information will be transferred to the central control system through GSM, the Global System for Mobile Communication. After the analysis of the collected information, a series of automatic irrigation operations will be finished through remote operation. The most vital feature of this kind of irrigation system is the integration of advanced technologies and modern traits, taking full advantage of the GSM network 科技. It not only covers a simple structure and few transmission lines but also has a low price in post-maintenance as well as a relatively low overall investment in the system. 因此, it can be widely popularized.
Irrigation using solar power
Using solar power as the initiated energy source, solar power irrigation stands for the utilization of water resources such as streams and groundwater for landscape irrigation. The solar power irrigation system is mainly comprised of a rain detector and a solar panel. The function of the rain detector is to detect rainy weather. If any rainy days are detected, then the system will be automatically shut off. The major role the solar panel plays lies in absorbing solar energy and then converting it into electrical pump power, which provides power for the electric pumps to extract water. The solar power irrigation system extracts water and then transfers it to the storage tank for preservation. Then it will be irrigated by sprinklers in the uphill direction. The irrigation system is mainly applicable for irrigation in remote areas as well as those regions without access to running water.
4. 智慧灌溉系統要多少錢?
The traditional irrigation water utilization rate remains extremely low, only ranging from 30% 到 40%. 然而, the micro irrigation utilization rate is able to register more than 90% and the water utilization rate has increased by 2.3 次. 事實上, in agricultural planting, the irrigation demand for each mu of land irrigation requires 20 tons. Each ton of water is charged at $0.5 and then the cost per mu of land is 60 yuan. If 4 times a year is needed for irrigation, then the annual cost is $60. 然而, if intelligent micro irrigation is utilized, the annual cost of around 136 yuan for each mu can be saved. Assuming that your planting area is 50 acres, then you are able to save $1000 per year.
Are you surprised when you do the calculation? The intelligent irrigation system also has a great benefit, which represents that a soil moisture sensor is installed in the field, which is able to achieve real-time monitoring of the soil moisture of agricultural planting by using the smart control functions. If the soil moisture being monitored is below the standard values, the system will automatically open up the irrigation system to water the agricultural planting. When the soil moisture that is monitored comes up to the standard values, the system will correspondingly shut down the irrigation system. 只有在調整好土壤濕度標準值後，灌溉系統才會實現自動化灌溉。.
事實上, 合理灌溉不僅可以提高每年灌溉利用率、節省灌溉成本，而且透過灌溉系統的自動化控制，可以實現更合理的農業種植灌溉。, 及時有效地對農作物進行灌溉，確保農作物生長，提升農作物品質. 現在, 智慧灌溉系統不僅可以實現灌溉自動化，還可以實現施肥控制自動化. 實現手機的對接, 您將在手機上了解土壤濕度和土壤養分的即時情況. 更重要的是, you can direct the irrigation system and fertilization system on the cell phone, which greatly boosts planting efficiency.

7. 智慧灌溉用的是什麼設備?
Wireless Collection Terminal
The wireless collection terminal refers to the equipment that is utilized to gather the environmental parameters of the irrigated area. LORA collectors which can be applied for soil temperature and moisture, 濕度, wind level and direction, liquid level, degree of sunlight, voltage, pressure or flooding, are equipped with batteries with low power consumption operation.
Wireless valve controller
The controller supports the remote turn-on and turn-off of valves, which contains various types of butterfly valves, pulse valves, or ball valves. A suitable pipe diameter such as DN15-DN250 can be selected on the basis of the actual application scenarios.
Smart gateways
The smart gateways can be applicable for data transmission of collection terminals. Working with start-stop valve controllers, the gateways can access up to 250 nodes, with automatic address configuration and mutual logical control between the nodes.
The wireless collection terminal detects and transmits the soil temperature and moisture data to the controller, which enters the control terminal and processes the signals sent by the wireless collection terminal (e.g. conversion, filtering, amplification) and then convert them. When the measured moisture is lower than the pre-setting value, the wireless valve controller is turned on and then irrigation starts. 同樣地, when the moisture is at the set value, the valve controller automatically turns off the irrigation. With the coordination of the smart irrigation system, intelligent control of irrigation can be fulfilled, thus effectively boosting automated production efficiency, reducing labor and management costs as well as significantly boosting efficiency.
8. 智慧灌溉應用案例
Dripping Irrigation
Dripping irrigation means that water and nutrients required for crop growth are delivered directly to the soil surface or the soil near the roots of the crop at a small flow rate in an even and accurate manner through the low-pressure pipeline system equipped with a special irrigator based on the crop’s requirement for water. Dripping irrigation can be mixed with fertilization and utilize the fertilizer applicator to apply soluble fertilizers with water to the root zones of the crops in order to timely replenish the water and nutrients that are necessary for the crops, thus enhancing crop yields. The main equipment includes a dripping pipe of irrigation, dripping head, filter, fertilizer application devices, pipe connection props, and control and measurement devices. The strengths contain that dripping irrigation saves water by 33%, conserving 33% more water than sprinkler irrigation and 81.6% more water than border irrigation. Compared with flood irrigation, dripping irrigation can enhance crop yields by 30%. 更重要的是, the dripping irrigation features water-saving, energy-saving, and labor-saving. 也, the soil is not easy to plate and weed growth is inhibited, as well as fertilization and watering can be finished at one time using the irrigation system.
This drawback is prone to blockage, which results in salt accumulation and root growth limitation.
Spraying Irrigation
Spraying is one way of irrigation in which pressurized water is sprayed into the air through a pipe with a nozzle, forming droplets and sprinkling them onto the farmland. This irrigation area not only saves around 40% more water than traditional ground irrigation but also has the strengths of soil, water and fertilizer conservation as well as labor-saving and the improvement of the microclimate of farmland.
同時, the use of mobile pointer-type water-saving sprinkler irrigation and water-saving equipment can better boost the utilization of water resources.
Micro Spraying
Micro-sprinkler is a low-pressure pipe system that sprays a small amount of water to the soil surface. There are two types of micro-sprinkler systems: fixed and mobile sprinklers. It is a water-saving irrigation technology between sprinklers and dripping irrigation, which requires less water pressure, high atomization, uniform spraying and less water. 更重要的是, water droplets are not as easy to be clogged as drip irrigation, but less water is discharged.
Under-Membrane Irrigation
Under-membrane irrigation is a technique of dripping irrigation which is under the membrane for irrigation. This technique features simple equipment, easy installation, easy use, and water and labor-saving, and not easy to be slabbed for the sol. Common gravel concrete pipes and plastic pipes are used as percolation pipes with certain pore space in the pipe wall to let water seep into the soil. Compared with ground irrigation, it consumes less water. 然而, it is slow down growth because of high cost, easily clogged and difficult maintenance.
Infiltration
Infiltration is one kind of porous tube or microporous pipe with small holes buried below the ground surface to let irrigation penetrate into the soil in a slow and even way as well as make the soil wet by the action of capillary force. The technique has the traits of water saving, energy saving, easily mid-tillage, soil structure protection, as well as weeds, diseases and insect prevention.
