"Raient Cloud Irrigation" is an automatic control technology based on modern agriculture and water-saving irrigation. It uses "big data, cloud computing, Internet of Things, and intelligent perception" technology to uniformly regulate crop water use and fertilization, and achieve precise crop timing and quantitative irrigation. At the same time, supplemented by soil moisture monitoring and meteorological information monitoring, it has realized the four major effects of water saving, fertilizer saving, energy saving and time saving. Compared with traditional irrigation, automatic irrigation saves more than 25% of water and more than 16% of fertilizer. The automatic switch valve is not limited by time and manpower, and can avoid the high evaporation period of daytime water for nighttime irrigation, and can complete the automatic switching of the rotation irrigation group within minutes, which greatly shortens the irrigation time and saves labor costs. The annual labor saving per mu is about 20 people.
The system can help producers easily realize automatic integrated water and fertilizer management, farmland moisture monitoring, farmland meteorological monitoring, and remote video monitoring. The system consists of cloud software system, WeChat client, mobile APP, on-site host, node controller, and data sensing acquisition terminal. It realizes intelligent control by organically combining with the water supply and fertilizer supply system. It can realize intelligent monitoring and control of water supply time, fertilization concentration and water supply in irrigation. The transmitter (soil moisture transmitter, flow transmitter, etc.) will monitor the irrigation status in real time. When the soil moisture in the irrigation area reaches the preset lower limit, the solenoid valve can be opened automatically. After the liquid level reaches the preset irrigation quota, the solenoid valve system can be automatically closed. The solenoid valve of the entire irrigation area can be scheduled to work in turn according to the time period, and the irrigation and moisture collection can be manually controlled. The entire system can coordinate work to implement rotation irrigation, fully improve irrigation water efficiency, save water and electricity, reduce labor intensity, and reduce labor input costs.
