For large-scale greenhouse facilities, if labor is used to regulate environmental conditions in the greenhouse, a large amount of manpower and time is required, and there are inevitable manual errors. With the innovation of agricultural science and technology, the popularization and application of Internet of Things technology, greenhouse machinery and equipment in the greenhouse also followed the transformation and upgrading.
In the greenhouse environment, a single-station greenhouse can use IoT technology to become a measurement control area for wireless sensor networks, using different sensor nodes and nodes with simple actuators, such as fans, low-voltage motors, valves, etc. The organization, which constitutes a wireless network, measures the substrate humidity, composition, pH, temperature, and air humidity, air pressure, light intensity, carbon dioxide concentration, etc., and then automatically adjusts the greenhouse environment, controls irrigation and fertilization operations through model analysis to obtain plant growth. The best conditions.
For the agricultural parks with greenhouses, the Internet of Things can also realize automatic information detection and control. With wireless sensor nodes, each wireless sensor node can monitor various environmental parameters. By receiving data from the wireless sensor aggregation node for storage, display and data management, all base test point information can be acquired, managed and analyzed, and displayed to users in various greenhouses in an intuitive chart and curve. At the same time, according to the needs of planting plants, various sound and light alarm information and SMS alarm information are provided to realize greenhouse intensive and networked remote management.
In addition, IoT technology can be applied to different stages of greenhouse production. In the greenhouse ready to put into production stage, by arranging various sensors in the greenhouse, such as temperature sensor and humidity sensor, the internal environment information of the greenhouse can be analyzed in real time, so as to better select the suitable varieties; in the production stage, the employees can use the objects. Networking technology collects various types of information such as temperature and humidity in the greenhouse to achieve fine management. For example, the time when the sunshade net is opened and closed can be sensed according to the temperature and illumination of the greenhouse. The heating system startup time can be collected according to the collection. The temperature information can be adjusted, etc.; after the product is harvested, the information collected by the Internet of Things can also be used to analyze the performance and environmental factors of plants at different stages, and feed back to the next round of production, thereby achieving more precise management and obtaining Better quality products.
The application of IoT technology in greenhouses can achieve the purpose of improving product quality, regulating growth cycle and improving economic efficiency, especially for efficient and accurate greenhouse management. For large-scale greenhouse facilities, if labor is used to regulate environmental conditions in the greenhouse, a large amount of manpower and time is required, and there are inevitable manual errors. If IoT technology is applied, it can be done in the shortest time with a click of the mouse, and it is very rigorous. This is also an important reason why the industry is optimistic about the application of the Internet of Things in modern agriculture.
With the popularization and application of Internet of Things technology, ordinary users can receive various real-time collected accurate sensor data through a computer or mobile phone at any time, and can also observe the overall situation of the greenhouse by remotely monitoring the video wireless sensor in the greenhouse. After the product is shipped out, the circulation process can be retrieved at any time by the corresponding barcode. The industry generally believes that the IoT agricultural intelligent monitoring system will be more widely used in facility agriculture.
Faced with the current situation of large-scale outflow of rural labor, the State promulgated Document No. 1 to promote innovative agricultural production and management systems, develop family farms, planting large households, and new farmers' cooperative organizations, and support leading enterprises to form large-scale enterprise groups through mergers, reorganizations, acquisitions, and holdings. . Establish a demonstration base for agricultural industrialization and promote the development of leading enterprise clusters. Promote the establishment of a close-knit interest linkage mechanism between leading enterprises and farmers, and adopt the methods of guaranteed purchases, share dividends, and profit returns to allow farmers to share more processing sales revenue. Encourage and guide urban industrial and commercial capital to the rural development of a breeding industry suitable for enterprise management. Increase support for agricultural industrialization funds, support leading enterprises to build raw material bases, save energy and reduce emissions, and cultivate brands.
It is not difficult to see that the formation and development of family farms, large agricultural growers, and farmer cooperative organizations will accelerate the promotion and application of this advanced technology of intelligent greenhouses in agriculture. Because these new agricultural economies are well-funded, skilled, and talented, they have the ability to use the new technology of smart greenhouses (wireless sensors) to increase the unit output value of land and maximize the benefits of family farms.
