Greenhouse automatic sprinkler irrigation system

Irrigation is a technical measure for supplementing the water required by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. The principle of irrigation is that the amount, frequency and time of irrigation should be determined according to the characteristics of plant water demand, growth stage, climate and soil conditions, and irrigation should be timely, appropriate and rational.

Improper irrigation will not only lead to low yield, but also may cause crop physiological diseases such as leggy, premature senescence, deformed fruit and root diseases caused by retting. Water is inseparable from each stage in the process of crop growth and development. Scientific water management is an important technology to obtain high-yield and high-quality crops.

With the rapid development of the country's economy and the strong support of national policies, the scale of agricultural production has been continuously improved, and the variety of agricultural products cultivated in greenhouses has become more and more large. The previous traditional artificial irrigation was particularly limited, with low efficiency and high labor costs. Irrigation relies on feeling, experience, and no reasonable data basis.

The rapid development of the Internet and the continuous innovation of science and technology make it possible for agricultural greenhouses to realize automation and informatization of production (Internet of Things). The Internet of Things realizes the connection between things and things by means of information technology, improves the automation management level of different industries, and reduces human intervention, thereby greatly improving efficiency and reducing the instability caused by labor. Relying on the Internet of Things technology, many R&D companies have developed an intelligent control system and applied it to greenhouse planting (smart greenhouse system). There are existing ones in the market, such as Shenzhen Aoyuexin Internet of Things, Guangxi Huiyun Internet of Things, etc.

The automatic sprinkler irrigation system of the greenhouse is a subsystem of the intelligent greenhouse system. In the system, the sensor equipment is used for real-time monitoring, the data is collected, and the system analyzes the data to determine the soil humidity, air humidity, etc., and automatically start the sprinkler irrigation equipment. When the system monitors that the water required by the crops has reached the most reasonable state, the sprinkler irrigation equipment will automatically turn off again.
